    Abstract: A cart wheel structure having a pair of wheels rotatably mounted to opposite ends of an axle rod. The axle rod is mounted to a base portion of a cart by a pair of fabricated brackets having an upstanding swivel post adapted to be received in swivel cavities provided on the cart base portion. The swivel cavities are adapted to receive the swivel post of conventional swivel caster whereby the cart may be provided with caster and non-caster wheels as desired. The cooperation between the axle rod and brackets provides an accurate maintained disposition of the wheels carried on the opposite distal ends of the axle rod.

    Abstract: A support leg (14) is attached to a ceiling structure (10) by means of a threaded stud (12) which mates with a threaded opening (18) in an insert (16) which is swage connected to the upper end of the support leg (14). A flat bar (20) is attached to the lower end of the support leg (14) so that it extends horizontally and makes a "T" with the support leg (14). An expansion clamp assembly (22) is carried by the bar (20). This assembly (22) is plugged into the tubular lower end portion (24) of the support leg (14). The uppermost part of the assembly (22) is a T-nut (48). The head (50) of the nut (48) includes a plurality of struck out barbs (76) having points (74) which penetrate into and grip the inner sidewall of the socket (24) when the assembly (22) is inserted into the socket (22). This secures the nut (48) against rotation. Following insertion, the member (20) is rotated, relative to the support leg (14), causing a relative endwise movement of a threaded rod (30), carried by the member (20), into the nut (48). This movement causes a cam surface (40) on a cam member (36) to be moved against wings (58) on one or more lock washers (54), in a direction deflecting the wings (58) outwardly. This deflection moves the edges of the wings (58) into a tight displacing engagement with the inner wall of the socket (24). Rotation of member (20) is continued until the member (20) is securely fastened to the support leg (14).

    Abstract: A locking device for locking the trailing wheels of a wheeled carriage, particularly of a perambulator, in the straight running position, the trailing wheels being mounted for pivotal movement about an upright axis extending perpendicular to their axis of rotation without intersecting it, wherein a support member carrying the axis of rotation of the trailing wheel is connected to a vertically extending sleeve mounted for rotation about its vertical axis in a concentrically surrounding cylindrical recess in the wheeled carriage, and wherein a resiliently deformable plug extends through the sleeve from above, the plug having a disk-shaped enlarged head portion engaging the rim of the upper end face of the recess and being in positive locking engagement with the sleeve so that the plug is non-rotatably connected therewith, the locking device including a substantially vertically extending engagement surface formed on the disk-shaped head portion for positive locking engagement with a locking member pivotally mounted on the wheeled carriage in the locking position thereof.

    Abstract: A dual wheel caster assembly consisting of an arcuate central horn carrying an axle with projections on either side of the horn that rotatably receive wheels. The axle has recesses that receive annular projections on the wheels for the purpose of retaining the wheels in position.A vertical opening in the horn receives a vertical pintle having a portion projecting upwardly from the horn adapted to be received in an associated piece of furniture. This pintle has two spaced thrust surfaces, a lower one adapted to directly engage the plastic horn and the other one adapted to engage a one piece plastic bearing.The two thrust surfaces are spaced such that the lower thrust surface initially carries most of the load until a certain amount of wear causes the load to be distributed between the two thrust surfaces from the associated piece of furniture.
