Abstract: A method and apparatus is described for applying unvulcanized gumstrips in precise overlapping relation on the marginal edges of an unvulcanized tire reinforcement belt or breaker to enhance the adhesion between the reinforcement belt or breaker and surrounding components of a finished, vulcanized tire.
Abstract: An internal combustion engine is described as having a unique angular relationship between the longitudinal axis of each piston cylinder, the center axis of any associated intake ports through which fluid enters the cylinder, and the longitudinal axis of any associated intake passageway for channeling fluid to the communicating intake port, to induce the fluid entering the cylinder to swirl about an axis which is angularly disposed to the longitudinal axis of the cylinder, rather than conventionally swirling about the longitudinal axis of the cylinder. The initial velocity of swirl is then accelerated by the principle of conservation of angular momentum to a more rapid and robust velocity during the compression stroke, thereby allowing the use of a much leaner fuel to air mixture.
Abstract: A bow beam, as well as a method of making the beam for the roof of truck trailer, is described as being initially extruded in a U-shape with a flat web which is heavier than a pair of legs which extend from the web. The extruded beam is then placed in a press where the free ends of the legs are bent to form a bow in the topside of the beam in spaced relation from the flat bottom web. Thus, the strength of the beam is optimized with a minimal amount of material.
Abstract: A method for making elastomeric cushion pads which can be used in off-the-road vehicles and in the draft gears of railroad cars. The method includes solidifying a molten mass of the elastomer under a pressure of at least 1000 psi to form an elongated slug of the elastomer which is then cut into a plurality of unfinished cushion pads which are then individually momentarily compressed to remove any permanent set or deformation of the pads which occurs when an uncompressed pad is initially compressed.
Abstract: A continuous, elongated hinge is described as having a hinge pin which is comprised of two solid pivot pins which are oppositely disposed and axially spaced from each other. The more closely spaced distal ends of the pivot pins have a pair of parti-cylindrical lugs with a slot between them. A flat spring extends between the pivot pins and is received in the slots between the lugs. A hollow sleeve extends between the pivot pins and surrounds the spring and lugs to provide a smooth, continuous outer cylindrical surface for the hinge pin.
Abstract: A clamping device for holding adjacent framing members of a metal picture frame together in mitered relation, is described as having an L-shaped steel plate comprised of two outstanding legs. Each leg is provided with a rotatable lever with a special cam that is designed to contact the framing members to cause frictional engagement between the legs and adjacent members when the members are in mitered relation.
Abstract: A clamping device is described as being a flat plate with depending flanges or arms which extend, firstly, from opposing marginal edges of the plate in a direction normal to the plane of the plate and, secondly, towards each other in a plane parallel to the plane of the plate and, lastly, terminate at free distal ends which converge towards each other in the direction of an opening in the plate, which opening threadably receives a screw which, when rotated into contact with the distal ends, causes expanded movement of the plate and arms into compressive relation with adjacent walls of a channel in which the device is employed as a fastening mechanism.
Abstract: An adapter for detachably mounting a drill bit on an extension, is described as having a button-type catch with outwardly diverging flanges, and a separate, split ring of spring steel for exerting a spring biasing force against the button catch. The button catch is seated in a recess which is formed in the split ring. In another embodiment of the invention, the split ring is provided with a protruding finger for initially holding the button catch, so that it can be easily inserted within the bore of the drill bit extension, prior to the final positioning of the adapter within the bore.
Abstract: A fishing lure is described as having a generally U-shaped body with a curved keel and flared front end to maintain the body in an upright position as the lure moves in the water and keep the lure from rotating as it moves.
Abstract: A safety cover for a duplex electrical outlet is described as having (i) an inner plate which is secured to the outlet, and (ii) an outer plate which is detachably hinged to the inner plate so that electrical plugs with metal prongs can be easily inserted into the outlets and removed therefrom as the outer plate is rotated from the inner plate. Further, the outer plate is completely removable from the inner plate as a safety feature so that tripping over an electrical cord, extending from the safety cover, is practically impossible because of this quick release feature of the safety cover. The inner and outer plates are uniquely hinged together by a hinge that is secured to one of the plates while being releasably joined to the other of the plates. The outer plate is designed to accommodate a conventional electrical plug. Further, the outer plate is provided with a special slot through which an electrical cord, attached to the plug, passes exteriorly of the cover.
Abstract: A unique fishing tackle box is described as having a number of separate housings which are adjacent the front of the box and in which spools of fishing leader line are mounted for rotating freely about their own axes which are, generally, in alignment and extend longitudinally of the box in parallel relation to the front of the box. The loose free ends of leader line from the spools, extend exteriorly of the box through a row of openings in the front of the box. Means are provided exteriorly of the box for cutting leader line as it is pulled from the openings.The tackle box is also provided with a flexible measuring tape that is mounted within the top cover of the box and is extensible therefrom, such that the top cover acts as an abutment from which a fish is measured using the measuring tape.The tackle box includes a special pivot pin on which a spool of fishing line is mounted for rotating freely as line is unreeled therefrom onto the reel of a fishing rod.
Abstract: A game that uses a gameboard which has a flat, smooth playing surface over which flat discs are slidable. A bumper rail borders the playing surface and causes discs to carom or ricochet back onto the playing surface. A plurality of pockets are disposed in the playing surface adjacent the bumper rail. The pockets are recessed into the playing surface, so that a disc will fall, by gravity, into the pockets. The pockets are made escape-proof by undercutting the bumper rail adjacent the pockets to extend the pockets under a part of the bumper rail. Thus, a part of the bumper rail overhangs each of the pockets and acts to prevent a disc from hitting the bumper rail and rebounding back over the pockets. The underside of the overhanging portions of the bumper rail, or the backsides thereof which the discs strike, may be sloped to deflect the discs downwardly into the pockets. The playing surface can be made to slightly overhang each of the pockets to help prevent the escapement of discs from the pockets.
Abstract: A device is described for holding a paint brush or roller in wet storage in the sealed chamber of a container. The chamber is designed to hold a paint dissolving solvent which creates an atmosphere in which a paint ladened brush or roller remains soft and pliable until it can be thoroughly cleaned, or until it is reused. The device includes an open top container which is provided with a cover for sealing the chamber, within the container, from the ambient atmosphere. The cover, in turn, is provided with a relatively small opening from which a number of slits, cut through the cover, extend in radial directions. The slits form a plurality of flexible, pie-shaped segments which coact with the opening to readily adapt to receiving various size handles of the paint brush or roller.
Abstract: A wall mounted liquid dispenser is described as having a vertically disposed tank in which liquid is stored, and a horizontally disposed valve assembly which is in juxtaposed position below the tank and controls the flow, by gravity, of liquid from the tank. The assembly has a vertical passageway which is aligned with the outlet opening of the tank through which liquid exits the tank. A valve stem and attached valve are reciprocable in a multi-diameter bore which is disposed longitudinally of the assembly. The valve is frusto-conically shaped and moves with the stem into and out of transverse blocking relation with the passageway. The end of the valve stem farthest from the valve, protrudes from the assembly and is pivotally attached to a lever which, when rotated in a direction away from the passageway, acts to move the valve out of blocking relation with the passageway, so that liquid is free to flow, by gravity, from the dispenser.
Abstract: A golf practicing device is described as being a golf ball which is tethered to a casting-type fishing reel which is attached to a portable bracket which, in turn, is detachably mounted adjacent the handgrip on the shaft of a golf club, such as a chipping iron or putter. A pair of eyelets are provided on the bracket opposite and, in line, with the fishing reel to guide the line from the reel as it pays out from the reel upon stroking or hitting the ball with the club head. Thus, after putting or hitting the ball, the player only need rewind the reel to return the ball for another practice shot.
Abstract: A paint brush is described as having a handle which is composed of two sections which are normally joined together in end-to-end relation, but which can be interchangeably used with a number of differently sized ferrules that contain fibers. The ferrules are each provided with a special adapter to which a single handle can be detachably mounted.
Abstract: A rotary hearth pyrolyzer is described as having a conically tapered roll for uniformly spreading waste material that is charged onto the hearth for pyrolyzation. The taper of the spreader roll is such that the linear speed at any point measured longitudinally of the roll corresponds to the speed of the rotary hearth at a point on the hearth opposite the point on the spreader roll. An angularly disposed scraper blade is positioned slightly downstream of the spreader roll, relative to the movement of the rotary hearth, and has a pair of marginal edges, one of which engages the spreader roll to remove waste material sticking thereto and the other of which edges terminates in spaced relation from the hearth to evenly spread or distribute waste material onto the hearth.
Abstract: A thermal energy savings hot water heater is described as having a steel storage tank around which is spirally wrapped, a plurality of separate groups of copper coils that are formed of hollow copper tubing that has a rectangular cross-section for optimum surface contact or confrontation with the storage tank. A separate refrigeration system is connected to each group of copper coils, so that refrigerant vapor, from the compressors, is circulated through the coils for heating water within the tank instead of circulating the vapor to the condensers where the heating energy of the refrigerant is wasted into the ambient atmosphere.
Abstract: A rotary railroad car coupler assembly is described as having a unique carrier which is designed for limited angling or tilting in the vertically elongated chamber of the striker, as the coupler rotates. The projecting lugs of the carrier which interlockingly engage the stops in the chamber of the striker, have sloping sides which diverge from the sidewalls of the chamber in a direction away from the coupler, rather than being parallel to the sidewalls as are the sides of the lugs of AAR Standard carriers. This improvement eliminates chattering that is normally occasioned when AAR Standard carriers are used in connection with a rotary railroad car coupler assembly and helps to prevent undue stress of the striker caused when the carrier becomes momentarily frozen or bound up in the striker as the coupler rotates.
Abstract: A flotation nozzle is described as having an enclosed chamber with unique fluid emitting orifices which are angularly oriented to produce a desired, directional flow of fluid. One such orifice is a dimple-shaped cavity which extends inwardly of the chamber and has a circular opening in the downstream portion of the dimple, relative to the flow of fluid in the chamber. The opening is tilted so that the direction in which the fluid flows from the opening substantially coincides with the resultant velocity vector of the velocity vectors due to static and dynamic fluid pressures at the orifice.
