Abstract: A cutting blade (58) is secured to the lower end of a flexible drive shaft (18). Drive shaft (18) extends from the blade (58) upwardly through a tubular handle (12).The upper end of the drive shaft (18) is connected to the output of a drive motor (14). The cutting blade (58) is within a housing (10) having a bottom opening (64) and three lower side openings (72, 74, 76). A cutting blade (58) includes a pair of section vanes (104) which when the cutting blade 58) is rotating serve to pull air into the housing (10) through the lower sidewall openings (72, 74, 76). The moving air picks up the cuttings and moves them rearwardly into a cuttings bag (92) which is connected to and supported from a rear portion of the housing (10).

Abstract: A hairdressing scissor assembly includes at least two pair of scissors each having a first scissor element and a second scissor element pivoted to the first scissor element. Each of the first scissor element and the second scissor element includes a handle. A first engaging element is formed on a first side of a first connecting member and releasably engaged with a side of one of the handles of one of the pairs of scissors. A second engaging element is formed on a second side of the first connecting member and releasably engaged with the other side of one of said handles of the other pair of scissors. The first connecting member can be replaced by a second connecting member having a thickness different from that of the first connecting member, thereby allowing a change in a spacing between the pairs of scissors.

Abstract: A saw chain for a chain saw including alternating center and side link pairs with certain of said side links being cutting links and certain of said center links preceding said cutting links having guard portions to inhibit kick back. Said guard portions including a forward and rearward guard portion, the rearward guard portion in overlapping relation with a depth guide of the cutting link. A relief spacing between the guard portions facilitates chip carriage and the guard portions cooperatively form a ramp to guide wood being cut over and onto the depth gauge for controlling the depth of cut taken by the cutting link.

Abstract: A table saw having a rotation structure includes a work table, a suspension rod, a swing seat, a rotation seat, a push lever, two torsion springs, and a threaded rod. When the threaded rod is rotated, the push lever is displaced horizontally to push the rotation seat to rotate, so that the circular blade is moved upward, thereby adjusting the cutting height of the circular blade. Thus, the push lever is urged by the elastic force of the two torsion springs, so that the push lever is closely and rigidly combined with the threaded rod, thereby eliminating the clearance between the push lever and the threaded rod, so that the cutting height of the circular, blade is adjusted exactly and precisely, thereby enhancing the cutting efficiency of the table saw.

Abstract: A powered dispenser for dispensing individual paper towel segments from a continuous roll of paper provided with spaced lines of tearing comprises a housing, a support for the roll of paper, a feed mechanism, and a control device. The control device senses the presence of a user to activate the feed mechanism, controls the amount of material which is dispensed from the housing for any one cycle, and prevents further dispensing of the paper until the previous segment is separated from the roll. The control device detects the leading edge of the paper to initiate monitoring of the length of paper to be dispensed to prevent any cumulative error in dispensing the segments.

Abstract: A cutting tool (10) adapted to produce chamfers along the edges of drywall panels. The tool (10,110,210) comprises a housing having a channel (18) defined by a base wall (13) and substantially parallel first and second sidewalls (15,17) that are substantially perpendicular to the base wall (13). A primary cutting blade (30) extends from the first sidewall (15) at an angle across the channel (18) toward the second sidewall (17). The primary blade (30) is configured to cut through an edge of a panel placed in the channel (18) as the cutting tool (10,110,210) is caused to move along the edge of the panel, thereby creating a chamfered edge on the panel. A second cutting blade (32) also extends from the first sidewall (15) and is positioned adjacent the primary blade (30) to create a perforation in the edge of the panel prior to the panel encountering the primary blade (30).

The cutter assembly has a blade movable to perform a severing operation wherein the blade cuts through the stock materials discharged from the processing assembly in a direction generally transverse to the feeding direction to sever a final product including the processed master and stock materials from a remainder of the supply of stock materials. The cutter assembly is removable from the frame for placement on a support surface to perform other cutting operations including a trimming operation wherein the blade is moved in the feeding direction.

Abstract: The present invention relates to a novel helical drum shear which is operable to cut a strip of material which moving at a first velocity. The cut is formed along a substantially straight line at a specific angle. The specific angle may be at an angle perpendicular to the feed direction thereby producing a squared cut. The helical drum shear comprises a means for cutting the material wherein the cutting means moves at a second velocity which is at a predetermined angle from the first velocity. The apparatus further comprises a means for moving the cutting means at a third velocity such that the combination of the second velocity and the third velocity is equivalent to the first velocity and the material is helically sheared along a substantially straight line oblique to the first velocity.

Abstract: A powered dispenser for dispensing individual paper towel segments from a continuous roll of paper provided with spaced lines of tearing comprises a housing, a support for the roll of paper, a feed mechanism, and a control device. The control device senses the presence of a user to activate the feed mechanism, controls the amount of material which is dispensed from the housing for any one cycle, and prevents further dispensing of the paper until the previous segment is separated from the roll. The control device detects the leading edge of the paper to initiate monitoring of the length of paper to be dispensed to prevent any cumulative error in dispensing the segments.
