Abstract: A furniture swivel of the thrust bearing type is taught herein having a top plate and bottom plate made entirely of an internally-lubricated polymer. A central top hole surface projects upwardly and integrally from the top plate, and a central top annular surface projects upwardly and integrally from the same plate wherein two flat, raised annular surfaces are integrally defined on the top inside surface of the top plate made of the polymer. The bottom plate is substantially similar to the top plate made entirely of the polymer and has a raised central bottom hole surface in face-to-face relation with the central top hole surface and a raised bottom annular surface in face-to-face relation with the top annular surface, wherein load support and low-friction rotation is maintained without overlain metal components.

Abstract: A simple, inexpensive rocker construction for a rocking chair comprising a pair of vertically-spaced, horizontally-disposed plates, the upper of which is adapted for securement to the undersurface of the seat of a rocking chair, and the lower of which is adapted to have swivel connection with a disc to which the supporting legs are attached. A pair of tubular posts are disposed vertically between the plates to provide a sweeping rocking action for the chair. Sturdy coil springs are connected between the plates to hold the latter assembled with the posts and to urge the chair to a normal position it would occupy if no one were sitting in the chair.

Abstract: The piercing unit of the present invention is a low-cost device having relatively few parts. The unit comprises a C-frame of cast iron. A hole is drilled from the top of the unit, through the top leg and part way into the lower leg. The bottom of the hole forms a seat for the lower end of the die sleeve. A punch holder slide is machined from tool steel for close-tolerance fit within the hole in the top leg. The slide has an opening extending inwardly from its lower end to receive the punch, and a threaded opening extending inwardly from its upper end to receive a stripper bolt. The punch holder slide abuts a shoulder adjacent to the inner end of the stripper bolt, and thus is backed up in its punching stroke. The punch abuts the threaded inner end of the stripper bolt and is thereby backed up in its punching stroke. Dog point set screws hold the punch assembled with the punch holder slide as the punch is being stripped from the steel it has just pierced.

Abstract: A rocker fixture for attachment to the bottom of a chair seat to provide a swivel and rocking action. The fixture comprises an upright post having its lower end received in swivel manner in the usual center socket carried by the legs of the chair. The upper end of the post is secured to a head bracket which has pivot connection with the legs of a channel, the latter being secured to a plate which is attached to the under-side of the chair seat. A bell crank lever is also pivotally connected between the legs of the channel and has one arm slidably engageable with an extension of the head bracket, and the other arm is acted upon by a spring-controlled member to urge said one arm to engagement with said bracket extension. The rocking action of the fixture works on a counter-balance principle so that weight shifting is required to tilt both to a backward position and forward from such position.
