A dual wheel caster body construction wherein the caster body frame is fabricated from a pair of sheet metal stampings nested together at an integral swivel stem socket and secured together in the area of confronting plate portions with an axle bearing through the plate portions for an axle carrying supporting wheels on opposite sides of the plate portions and a wheel cover also fabricated from a sheet metal stamping supported on and secured to the body frame stampings.

Dual wheel caster body structure

This invention relates to a socket for mounting casters and which preferably is of integral construction, made from a flat blank and formed to provide an upstanding tubular socket of opposed semi-circular sections, tapered adjacent their upper portion and partially overlapping at the top end of the tube, with spurs projecting outwardly thereof intermediate the height of the tube and having a bottom flange including upstanding teeth having wedge shaped top edges.

Socket for caster mounting

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.

Bushing and grease retainer for casters

The present invention relates to a new and improved apparatus for the high speed and continuous forming of parts requiring a protective plastic coating to be deposited over a portion of such parts.
