BACKGROUND

[0003] 1. Field of Invention

[0004] This invention relates to street sweeping brooms brushes, specifically brooms brushes mounted to vehicles for sweeping roadways, parking lots and any surface requiring the utilization of a rotary or push pull type broom brush, vehicular mounted.

[0005] 2. Description of Prior Art

[0006] Research of sweeping requirements for street sweeping indicated a need for a broom brush that would be overtly more aggressive, easier to mount and dismount, be fully recyclable, while providing increased sweep life and sweep capability.

[0007] The aggressiveness of industry standard brooms brushes are lacking in their ability to remove compacted dirt, heavy debris, and weeds in an efficient and expedient manner. Industry standard brooms are manufactured utilizing a carbon steel spring wire of small dimensional size, which inhibits industry standard brooms to perform in an aggressive manner.

[0008] Industry standard brooms have their wire set at 20 degrees pitch in the wire segment mounting backer. This pitch angle is insufficient for improved sweep capability and broom brush life.

[0009] Mounting and dismounting of brooms brushes on sweeping vehicles is a time consuming as well as hazardous operation for the person performing such mounting and dismounting. Industry standard brooms have their fastening nuts either imbedded in a plastic segment mounting back or loose fit on the under side of a wood mounting back. This creates problem issues for removal of mounting fasteners when corrosion is prevalent. Person that would be required to remove corroded fasteners would need to utilize a cutting torch to remove the corroded fasteners. Therefore, a need for a broom brush that would be easier, faster and safer to mount and dismount on the vehicle was observed. The quantity of mounting fasteners, type of fastening system utilized is insufficient to warrant easier, faster and safer mounting and dismounting of broom brush on machines.

[0010] Additionally, recyclability of industry standard brooms could only be accomplished by extensively reworking used brooms brushes by separating the carbon steel wire from the plastic segment or wood segment wire mounting backing.

OBJECTS AND ADVANTAGES

[0011] Accordingly, besides the objects and advantages of industry standard brooms brushes described above, several objects and advantages of the present invention are:

[0012] a) to provide a broom brush that utilizes a single piece mounting back for brush wire and mounting of broom to machine, rather than multi segmented mounting backs as utilized by industry standard brooms brushes;

[0013] b) to provide a broom brush with a mounting fastening system that is easier, faster and safer for mounting and dismounting of brooms brushes, by utilizing less fasteners per broom assembly;

[0014] c) to provide a broom brush where fasteners protrude up through broom mounting plate on the machine, with fastening nuts on top of broom mounting plate, which alleviates fastening system corrosion problems that would require the use a cutting torch or other mechanical means to remove corroded fasteners;

[0015] d) to provide a broom brush with an increase in wire pitch angle from 20 degrees to 30/35 degrees as set in the broom brush mounting back;

[0016] e) to provide a broom brush that will increase the usage life over industry standard brooms;

[0017] f) to provide a broom brush that is more aggressive than industry standard brooms by utilizing wire rope (cable) as a component replacing industry standard brush wire as necessitated by sweeping application requirements;

[0018] g) to provide a broom brush which is recyclable with no rework requirements as would be necessitated of industry standard plastic segment or plywood segment brooms brushes;

[0019] h) to provide a broom brush to better clean the environment;

SUMMARY

[0020] It is a principle object of the present invention to provide a broom brush to the sweeping industry that is overtly more aggressive than the industry standard broom brush utilized, while increasing the usable sweep life, sweep capability and ease of mounting and dismounting.

DETAILED DESCRIPTION

[0060] Description—FIGS. 1A and 1B—Preferred Embodiment

[0061] A preferred embodiment of the improved sweeping broom brush is illustrated in FIG. 1A (top view) and FIG. 1B (side view) single piece broom brush mounting flange. Single piece broom brush mounting flange 1 is formed from steel of dimensional thickness as required by broom brush application requirements; or an injection molded plastic.

[0062] Outer diameter brush pack mounting flange 2 is formed at an angle. Degree of angle is based upon applicable broom size application requirements. Outer brush pack mounting flange 2 is of a width necessary to accommodate required brush pack assemblies FIGS. 2A 7, 2C 7, 3D 20, 6A 28, 6B 28 to be affixed to the outer brush pack mounting flange 2 or inserted through openings in plastic back.

[0063] Broom brush mounting fastener holes 3 are positioned as required by broom brush mounting application into the single piece broom brush mounting flange 1 (FIG. 1A). Mounting fastener size, radius of mounting holes and quantity of mounting holes is mandated by specific sweeping vehicle mounting application.

[0064] Center clearance opening 4 is sized to accommodate required clearance for broom brush mounting plate drive motor attachment protrusions on sweeping vehicle.

[0065] It is well known in the art as to how to produce such single piece broom brush mounting flange.

[0066] FIGS. 2A, 2B, 2C, 2D, 2E, 3A, 3B, 3C, 3D, 4A, 4B, 4C, 5A, 5B, 5C, 5D, 6A and 6B—Additional Embodiments

[0067] Additional embodiments are shown in FIGS. 2A, 2B, 2C, 2D, and 2E; in each case the wire rope (cable) brush pack assembly 7 dual strand is assembled by inserting wire rope (cable) 6 into tube collar 5, to a specified overall length as required by broom brush application requirements. Assembled components 5 and 6 are then placed into a crimping die, so as to crimp collar 5 to wire rope (cable) 6 at the end of tube collar 5 that wire the rope (cable) 6 is inserted into. Therefore completing wire rope (cable) brush pack assembly 7. Prior to assembly of wire rope (cable) brush pack assembly 7, wire rope (cable) brush pack 7 may require an alternative mechanical fastening flange 8 (FIG. 2B) mated to tube collar 5 prior to final assembly of wire rope (cable) brush pack assembly 7. Alternative mechanical fastening flange 8 is affixed to tube collar 5 by either welding, soldering or brazing. Alternative mechanical fastening flange 8 has a center opening 9 (FIG. 2B) sized to accept a mechanical fastener of a size specified by broom brush application requirements.

[0068] When wire rope (cable) brush pack assembly 7 is assembled and crimped 10 it is sheathed 11 with either a PVC, Vinyl, Lead Free Solder or other material that would be deemed appropriate as a sheathing for a specific application, to maintain the integrity of the wire rope (cable) 6 when the wire rope (cable) 6 is in contact with the surface being swept.

[0069] FIGS. 2D and 2E, show single strand wire rope (cable) brush pack assemblies 12 and 13. Single strand wire rope (cable) brush pack assemblies 12 and 13 are assembled by inserting a single strand of wire rope (cable) 6 into tube collar 14 or tube collar 15, to a specified overall length as required by broom brush application requirements. Single strand wire rope (cable) brush pack assembly 12 and 13 are crimped 17. Crimping is accomplished by placement of sub assembled single strand brush pack assemblies into a crimping die so as to secure wire rope (cable) 6 into tube collar 14 or tube collar 15. After wire rope (cable) brush pack assemblies 12 and 13 are crimped, they are sheathed 11 with either PVC, Vinyl, Lead Free Solder or other material that would be deemed for a specific application. Sheathing 11 is applied to maintain the integrity of the wire rope (cable) 6 when the wire rope (cable) 6 is in contact with the surface being swept.

[0070] FIGS. 2D and 2E, show single strand wire rope (cable) brush pack assemblies 12 and 13 manufactured with two different types of tube collars 14 and 15. To manufacture a single strand wire rope (cable) tube collar 14, tube collar is placed into a forming die that forms one end of tube collar 14 to create a flange of dimensional size required by specific application requirements integral to tube collar. Tube collar 15 is made by affixing washer 16 to tube collar 15, by either welding, soldering or brazing washer 16 to one end of tube collar 15. Washer 16 is so centered on tube collar 15.

[0071] FIGS. 2A, 2C, 2D and 2E, show multi strand and single strand wire rope (cable) 6 brush pack assemblies with sheathing 11 applied. For application of the PVC sheathing a brush pack assembly 7, 12 or 13 is washed to remove any grease or oils, then is placed into an oven and heated to 400 degrees F. When brush pack assembly 7, 12 or 13 is at required temperature, they are removed from the oven and dipped into the liquid PVC with wire rope (cable) 6 ends downward. Brush pack assemblies 7, 12 or 13 are dipped to a depth that would allow the liquid PVC to sheath the entire brush pack assembly up to and including crimp 10 and 17 on tube collar 5, 14 or 15. Suspension time in the liquid PVC is mandated by the mill thickness required. Brush pack assemblies 7, 12 or 13 are then removed from the liquid PVC and placed back into a 400 degree F. oven for final cure. Final cure dwell time is mandated by type of PVC used.

[0072] Application of sheathing 11 with a Vinyl material is accomplished in the following manner: A select dimensional size vinyl tube is warmed to a temperature that allows the vinyl tube to become flexible. The vinyl tube is then slid over the wire rope (cable) 6 up to tube collar 5, 14 and 15. Vinyl tube is allowed to extend past end of wire rope (cable) 6.

[0073] Application of sheathing 11 with a Lead Free Solder is accomplished in the following manner: Brush pack assemblies 7, 12 and 13 are washed to remove any oil and grease. Brush pack assemblies 7, 12 and 13 are heated to temperature required for type of fluxing agent and Lead Free Solder utilized. Brush pack assemblies 7, 12 and 13 are then dipped into a liquid fluxing agent with wire rope (cable) 6 ends down up to and including crimp 10 and 17 on tube collar 5, 14 and 15. Brush pack assemblies 7, 12 and 13 are then immediately dipped into a molten bath of Lead Free Solder with wire rope (cable) 6 ends down for a prescribed dwell time as mandated by type of Lead Free Solder utilized. Brush pack assemblies 7, 12 or 13 are dipped to a depth that would allow molten Lead Free Solder to sheath the entire brush pack assembly up to and including crimp 10 and 17 on tube collar 5, 14 and 15.

[0074] FIGS. 3A, 3B, 3C and 3D, show carbon steel wire brush pack assembly manufactured by inserting longitudinally a specified quantity, length of and dimensional cross section of carbon steel brush wire as a bundle 19, equidistantly centered in collar 18. Subassembly 3A is then placed into a forming die which flattens tube collar 18 and allows carbon steel brush wire bundle 19 to flatten out to a specified width filling tube collar 18 to each interior side of tube collar 18. Tube collar 18 and carbon steel brush wire 19 as an assembly FIG. 3B is then placed into a second forming die which changes assembly FIG. 3B from a longitudinal assembly to a “U” shaped assembly FIG. 3C. Thereby formiing the completed carbon steel wire brush pack 20 FIG. 3C (side view) and 20 FIG. 3D (front view).

[0075] FIGS. 4A, 4B and 4C show method of affixing brush pack assemblies 7, 20 and 28, to single piece metal broom brush mounting flange 1, to outer brush pack mounting flange 2. Single piece broom brush mounting flange 1 is placed onto an indexing fixture so brush pack assembly wire rope (cable) 7, carbon steel wire brush pack assembly 20, and Polypropylene wire brush pack assembly 28 can be affixed to outer brush pack mounting flange 2. Indexing fixture will equidistantly space prior mentioned brush pack assemblies on the outer brush pack mounting flange 2. When single piece metal broom brush mounting flange is set onto the indexing fixture and the first indexing point has been established, brush pack assembly 7 or 20 or 28 is selected to be affixed at the first indexing point. Brush pack 7 or 28 is positioned on the outer brush pack mounting flange 2, so tube collar 5 is centered equidistant from the inner and outer edge of the outer diameter brush pack mounting flange 2. Brush pack assembly 7 or 28 is then welded 23 to the outer diameter brush mounting flange 2 on the inner and outer bias of tube collar 5.

[0076] Brush pack assembly 20 (FIG. 4B) is located on the outer brush pack mounting flange 2 at the prescribed index point mandated by the indexing fixture. Brush pack assembly 20 is positioned with the downward end of the brush pack assembly offset below the downward edge of the outer brush pack mounting flange 2. Brush pack assembly 20 is then welded 23 to the outer brush pack mounting flange 2 on the inside and outside end of tube collar 18 of brush pack assembly 20.

[0077] FIG. 4D show single strand wire rope (cable) brush pack assembly 12 or 13 affixed into an injection molded plastic or wood broom mounting back 21. Injection molded plastic broom mounting back 21 would be manufactured with openings to accept single strand wire rope (cable) brush pack assembly 12 or 13 and carbon steel brush wire 19 (FIG. 3A) less tube collar 18 (FIG. 3A). A bundle of carbon steel brush wire 19 (FIG. 3A) is folded in half and inserted through openings in injection molded plastic or wood mounting back. Openings in either type back could alternate to accept either type of single strand wire rope (cable) brush pack assembly 12 or 13 and carbon steel brush wire 19 (FIG. 3A) less tube collar 18 (FIG. 3A) alternating around the diameter of mounting back 21. Injection molded plastic or wood broom mounting back 21 could additionally be designed to have all openings accept a single strand wire rope (cable) brush pack assembly 12 or 13. Top of the openings in either type broom mounting back to accept a single strand wire rope (cable) brush pack assembly 12 or 13, would be recessed 22 for proper clearance for mounting to sweeping vehicle broom brush mounting plate. When broom brush assembly is mounted to sweeping vehicle broom brush mounting plate, recessed opening would allow for entrapment and securing of single strand wire rope (cable) brush pack assembly 12 or 13 into mounting back. Mounting of single strand wire rope (cable) brush pack assembly 12 or 13 in this manner alleviates any possibility of loss of wire rope (cable) brush pack assemblies 12 or 13 when broom brush assembly is mounted and used.

[0078] FIGS. 5A, 5B, 5C and 5D show a spacer that is used in conjunction with a single piece broom mounting flange 1 (FIGS. 1A and 1B), when single piece broom mounting flange 1 (FIGS. 1A and 1B) is manufactured utilizing cold rolled steel. Spacer 24 (FIGS. 5A (side view) and 5B (end view)) would be machined from a UHMW material, Nylon or other thermoplastic material conducive to application of broom brush mounting to sweeping vehicle. Spacer 24 would have a center opening sized to fit a specified fastener size as required by specified broom brush application requirements. Spacer 26 (FIGS. 5C (side view) and 5D (end view)) would be manufactured from tube material of metal of a gauge and length specified by application of broom brush mounting requirements. Length of spacer 24 and 26 would be mandated by specified broom brush application requirements.

[0079] FIGS. 6A, 6B and 6C show a Polypropylene wire brush pack assembly 28 (FIGS. 6A (side view) and 6B (front view)). Polypropylene brush pack assembly is manufactured by inserting longitudinally, a specified quantity, size and length of Polypropylene wire 27 into one end of tube collar 5 to form a subassembly FIG. 6A. Overall length of brush pack sub assembly is adjusted to a specified length as per broom brush application requirements. Brush pack sub assembly is then placed into a crimping die that applies a crimp 10 onto tube collar 5 which secures Polypropylene wire 27 into tube collar 5. Crimping operation 10 is performed at the end of tube collar 5 where Polypropylene wire is inserted into tube collar 5. This operation forms a completed Polypropylene wire brush pack assembly FIG. 6B (front view) and FIG. 6C (side view)). Prior to assembly of Polypropylene wire brush pack assembly 28, Polypropylene wire brush pack assembly may require an alternative mechanical fastening flange 8 (FIG. 2B) mated to tube collar 5 prior to final assembly of Polypropylene wire brush pack assembly 28. Alternative mechanical fastening flange 8 is affixed to tube collar 5 by either welding, soldering or brazing. Alternative mechanical fastening flange 8 has a center opening 9 (FIG. 2B) of a size to accept a mechanical fastener of a size specified by broom brush application requirements.

[0080] FIG. 7A shows an assembled broom brush 29 utilizing carbon steel wire and wire rope (cable).

[0081] Advantages

[0082] From the description above, a number of advantages of my improved street sweeping broom brush become evident:

[0083] (a) The utilization of a single piece metal broom brush mounting flange allows for an increase in the degrees of pitch of the wire in the mounting flange as compared to industry standard brooms, to allow for a longer sweep life and improved sweep capability of the broom brush.

[0084] (b) The design of the improved broom brush allows for a larger broom brush diameter where the wire ends meet the surface being swept, allowing the sweeping machine to work farther off of curbing, therefore better protecting debris pickup equipment.

[0085] (c) By utilizing a single piece broom brush mounting flange, the quantity of fasteners and design of the fastening system required for mounting the broom brush assembly to the sweeping vehicle, are improved as to the method of mounting and dismounting the broom brush assembly to the sweeping vehicle.

[0086] (d) Utilizing a single piece broom brush mounting flange, manufactured of metal or plastic material, allows for the affixing of brush pack assemblies including brush pack assemblies using wire rope (cable) that improves the sweep aggressiveness of the broom brush assembly for difficult sweeping environments.

[0087] (e) Utilizing a single piece broom brush mounting flange, manufactured of metal allows for varying the configuration of a broom brush with varying brush pack quantities and types to tailor a broom brush to specific sweeping requirements.

[0088] (f) Utilizing wire rope (cable) as a substitute for and in conjunction with standard brush wire increases dramatically the available sweep life of the broom brush when compared to the sweep life of the industry standard broom brush.

[0089] (g) Utilizing wire rope (cable) as a substitute for and in conjunction with standard brush wire increases the ability of the broom brush to improve the sweep capability of a broom brush in sweeping compacted debris and weeds in curbing and on roadways.

[0090] (h) Configuring the various types of brush packs to the broom brush assembly allows for a wide range of broom brush usage that would be required for various types of sweeping encountered in the sweeping industry.

[0091] (i) Tailoring the configuration of brush pack types to either a specific sweeping application or a broad range of sweeping applications allows versatility not available with industry standard brooms brushes.

[0092] (j) The improved broom brush assembly will substantially reduce sweeping costs and improve sweep capability as well as sweeping speeds.

[0093] (k) The improved broom brush allows for recyclability with the single piece metal broom brush mounting back, when brush packs 7, 12, 13, and 20 are utilized, with no rework requirements for placement into a metals recycling waste stream.

[0094] Operation

[0095] The manner of using the improved broom brush assembly is the same as industry standard brooms brushes available. With the exception of the improved mounting and dismounting feature. Sweeping vehicle broom brush mounting plate is extended outwardly from the vehicle and lowered to a position just above the broom brush assembly. Sweeping vehicle broom brush mounting plate when extended will have a noticeable forward down angle. Sweeping vehicle broom brush mounting plate is rotated so that a mounting plate fastener hole is facing forward. Broom brush assembly is positioned so that one mounting fastener (bolt) is directly underneath and aligned with the mounting plate fastener hole in the vehicle broom brush mounting plate that is facing forward. Broom brush assembly is then raised upward so mounting fastener (bolt) protrudes upward through vehicle broom brush mounting plate fastener hole. When threaded end of mounting fastener (bolt) is protruding upwardly through vehicle broom brush mounting plate, a fastening nut is started on mounting fastener (bolt). At the rearward facing side of the vehicle broom brush mounting plate, the broom brush assembly is raised so that a mounting fastener (bolt) is aligned with a rearward facing broom brush mounting plate fastener hole. Once alignment is achieved mounting fastener (bolt) is allowed to protrude upwardly through vehicle broom brush mounting plate. Fastening nut is then started on mounting fastener (bolt). Additional mounting fasteners (bolts) in the broom brush assembly will now be protruding upwardly through vehicle broom brush mounting plate and remaining fastening nuts are started on threaded end of remaining broom brush mounting fasteners (bolts). Fastening nuts are then tightened to finish mounting procedure. When broom brush assembly is mounted to vehicle broom brush mounting plate, complete assembly is moved to the transport position on sweeping vehicle.

[0096] Removal of broom brush assembly is achieved by removing all fastening nuts allowing the broom brush assembly to fall away from the vehicle broom brush mounting plate. With broom brush assembly fastening nuts on top of vehicle broom brush mounting plate, corrosion problems normally associated with industry standard broom brush fastening system are alleviated.

[0097] After broom brush assembly has been mounted to vehicle broom brush mounting plate, sweeping vehicle is moved to the sweeping environment for sweeping. Broom brush is extended into the sweeping position required. Broom brush rotational speed as well as vehicle speed is adjusted for optimum sweeping capability, in relation to the sweeping environment broom brush is to be used.

[0098] Broom brush assembly configuration of brush packs will mandate broom brush rotational speed and vehicle speed for the environment being swept.

CONCLUSION, RAMIFICATIONS, AND SCOPE

[0099] Accordingly, the reader will see that the improved broom brush will improve the mounting and dismounting, increase the sweeping capability, available sweeping time and aggressiveness required for difficult sweeping environments. Furthermore, the improved broom brush has the additional advantages in that:

[0100] It permits a larger diameter broom brush than industry standard brooms brushes where wire ends meet the surface being swept which allows the sweeping vehicle to work farther away from curbing and obstacles;

[0101] It permits the broom brush to be configured in a manner conducive to various sweeping application requirements;

[0102] it permits ease of recyclability where no rework is required to place the spent broom into a recycling waste stream, whereas plastic back or wood back brooms brushes would require rework;

[0103] it permits an operator or mechanic to mount and or dismount the improved broom brush in a safer, easier and more expedient manner, due to the accessibility of mounting fasteners;

[0104] it allows the sweeping vehicle to move at a greater speed while sweeping difficult environments where industry standard brooms brushes require a slower sweeping speed to achieve the same quality of sweeping as the improved broom brush;

[0105] it provides an improved sweeping characteristic for cleaning of the environment;

[0106] it provides a longer sweep usage life of the broom brush due to the increase in pitch of the brush wire as compared to industry standard brooms brushes;

[0107] Although the description above contains many specifics, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. For example, a broom brush assembly can be made in a drum type broom brush. Mounting of brush pack assemblies can be accomplished with the aid of a mechanical fastener, degree of pitch can be altered for specific requirements, brush pack assemblies can be manufactured with many differing materials depending upon a specific sweeping requirement, plastic or wood segment broom brush mounting backs can be reworked or designed to accept single strand wire rope (cable) brush pack assemblies, etc.

[0108] Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
