Abstract: An axle coupler comprises driver teeth to engage teeth of a corresponding driver; a central aperture having a central axis and a circumference; and the central aperture including axle teeth circumferentially surrounding the central axis; each axle tooth having a first dimensional direction parallel to the central axis; each axle tooth having a second dimensional direction orthogonal to the first dimensional direction; a recess formed in each axle tooth to form a first axle tooth portion and a second axle tooth portion.

Abstract: A bowling overshoe includes an upper formed from a stretchable sheet material and two outsole portions attached independently of each other.

Abstract: A link for facilitating the joining of two rods while compensating for manufacturing irregularities in rod length and other manufacturing and assembly tolerances to produce a rigid assembly of proper length including a clip base for receiving an end of each rod and a sleeve to lock the assembly. The clip has an opening on one end for receiving a first rod and a threaded opening and longitudinal recess at the opposite end for receiving a threaded end of the second rod. The second rod may be pushed transversely to its axis into the recess and opening at any point along the opening to rigidly link the two rods together while compensating for manufacturing and assembly tolerance variations. The sleeve is telescopingly locked over the recess to secure the second rod in the clip.

Abstract: A self-locking retainer, actuated by pushing a piece to be retained into the retainer, includes opposed molded parts hinged together, one pair of parts, on opposite sides of a hinged portion, movable together to form a base and a retention plug with integral locking dogs, and a second pair of parts mounted on the base of the first pair formed as hinged jaws with opposed recesses to clamp a piece to be retained. Detent means on the jaws and the base of the first pair of parts interlock to hold the jaws together when pushed together by a part to be retained.

Abstract: A quick connect fitting in which tubing can be inserted into a pre-assembled fitting where it will become sealed and locked against pull-out. A main fitting body has an open-ended recess in which is located a movable piston to seal against the body and an inserted tube. The piston wedges over a conical extension on a sealing gland retained by a screw-on cap. The sealing gland has rearward, circumferentially spaced fingers radially movable. An axially shiftable ring, in one position, allows the fingers to expand to receive the tube, and, when shifted to a second position, moves the finger to engage the extension surface of the tube to lock against withdrawal.

Abstract: A quick connect fitting for tubing which can be inserted into a pre-assembled fitting where it will become sealed and locked against pull-out. A main fitting body has an open-ended recess in which is located a movable piston to seal against the body and an inserted tube. The piston wedges over a conical extension on a sealing gland retained by a snap-on cap, the gland and the cap having complemental spherical surfaces to allow swivel movement of the tube without disturbing the seal in the tube. A locking ring retainer grabs the tube annularly and bears against the piston to resist pull-out.

Abstract: This invention provides a rotary floor cleaner having means for detachably securing the drive mechanism to the base of the unit, said means including wedge blocks against which the drive mechanism may be wedged and a rotatable cam for incrementally forcing the drive mechanism into wedging engagement between the wedge blocks and the cam.

Abstract: To augment the spin and lift imparted to a bowling ball as it leaves the hand of the bowler, there are mounted in the finger holes inserts having inwardly protuberant ridges at the rims thereof. The tips of the fingers are hooked around these ridges when the ball is gripped, and continue to be at least partially hooked therearound during release of the ball, so that there is sufficient force imparted to the ball during release to create improved spin and lift. There is provided on the inner ends of the inserts walls having central holes therethrough, for purposes of aiding insertion of the inserts, relieving air pressure, and permitting inspection at any time.

Abstract: The improved cleaning tool disclosed herein is particularly designed for cleaning walls and ceilings. The tool includes a novel block assembly that is mounted on an end of a wand adapted to be held and manipulated by the person doing the cleaning and that includes one surface adapted to be disposed adjacent to the wall or ceiling to be cleaned during the cleaning operation. Two continous rows of channel bristles are mounted on the one surface of the block assembly and extend across the one surface, in a direction transverse to the normal, back and forth path of motion of the block assembly while in usage. The block assembly includes a plurality of nozzles that are designed to wet the rows of channel bristles with cleaning fluid so that the cleaning fluid will flow to the distal ends of the bristles and then be applied, as a thin film, to the wall or ceiling to be cleaned. Vacuum suction slots are disposed between the rows of channel bristles.

Abstract: A device for supporting and stabilizing a cylindrical, open-topped container as the container is tipped to discharge its contents into a receptacle. The device includes a pivot member connected by spaced arms to a brace member, legs extending downward from the arms, and an elastic fastening member. The legs hook about a lip on the container, and in cooperation with the fastening member, which loops about a projection on the container, hold the brace member against a side of the container. The pivot member may then rest on the edge of the receptacle to provide a stable pivotal axis for tipping the container.

Abstract: An improved tool is disclosed for cleaning hard surface floors. The tool includes a scrubbing block which is pivotally mounted on the lower end of a handle that may be manipulated by a person standing by the tool. A housing is mounted about the scrubbing block and is connected with the scrubbing block by leaf springs so as to permit the housing to "float" with respect to the scrubbing block. The housing includes a bottom surface and curved, generally transverse, front and rear channels that are disposed adjacent to the front and rear of the housing, that are open to the floor, and that are connected with a vacuum conduit. Squeegee blades are disposed in the channels and are carried therein by support members pivotally mounted on the housing. The support members include a plurality of depending feet which support the housing so that its bottom surface is above the floor to be cleaned.
