Abstract: A tubular metal chair leg is formed by a die to provide on its end an integral socket for the direct reception of the pintle of a caster or shank of a glide. The construction enables the use of identical casters and glides on tubular as well as cast legs. The necessity for stocking two sizes of glides for tubular and cast legs plus inserts for casters for tubular legs is eliminated.

Abstract: A swivable caster includes plastic wheel means rotatably mounted on a plastic stem at the lower end thereof. Near its upper end the stem is provided with an annular groove having a nylon split ring disposed therein and having its peripheral portion disposed outside of the groove. This peripheral portion engages a downwardly facing shoulder that extends inward from the internal wall forming a socket that receives the stem. Engagement of the split ring with the shoulder limits insertion of the stem into the socket. During this insertion the split ring is compressed radially so that it acts as a friction means to hold the stem in the socket and also provides a bearing for swiveling of the stem.

Abstract: This invention relates to a pivot bushing for casters and in which the stem for associating the caster with an article it is to support, is mounted. The bushing preferably is non-metallic and fits into the caster stem mount with a close fit for at least a portion of its depth with a clearance fit in the lower area where the stem must pass beyond an annular shoulder in the bushing for retention. The bushing has a fully closed lower end for retaining grease used to lubricate the stem for rotation in the bushing. The upper end of the bushing includes an integral cap-like enclosure, or shroud, which overlies the top end of the tube for mounting the bushing and stem in a caster and which lends a finished appearance in this area. A vertical exterior bead on one side of the bushing serves to engage a seam in the mounting tube to position the bushing properly relative to the caster.

Abstract: A wheel mount adapted to be used on the bottom side of a suitcase to permit wheeling the latter. The mount is formed so as to minimize the likelihood of damage to the mount and to the wheel which it supports. The mount is elongated in a longitudinal direction and its sidewalls are slantingly disposed relative to the wheel in order to minimize damage when struck by another object. One form of the invention is made from a block of plastic or the like and other forms are made of formed sheet metal.
