UNITE STATES PATENT OF ICE.
WILLIAM HESSMAN, OF RICHMOND, INDIANA.
" CASTER.
ISPECIFICATION forming part of Letters Patent No. 250,811, dated December 13, 1881,
- Application filed September 1,1881. (Model) To all whom it may concern.-
Be it known that I, WILLIAM HESSMAN, of Richmond, in the county of WVayne, and in the State ofIndiana, have invented certain new and useful ImprovementsinFurnitureGasters; and I do hereby declare that the-followin g is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.
This invention relates to casters which .are especially designed for furniture and for other purposes; and the nature of my invention and improvemeutconsists in the combination, with the saddle, which is allowed to swivel about a vertical stem or post on the attaching-plate, and which is free to oscillate, of a gimbalbearing, a square not on said post, a washer therefor, and a central retaining-screw, all being constructed and arranged as will be fully understood from the following description.
In the annexed drawings, Figure l is an elevation of the improved caster. Fig. 2 is a bottom view. Fig. 3 is a side view. Fig. 4 is a Similar letters of reference indicate correspondin g parts.
The letter A designates the attaching-plate of the caster, which is ofcircular form and constructed with a central stem or hub, to, through which is tapped a hole to receive a screw, b. On the lower end of the post or hub a a pris niatic nut, c, is formed, adapted to receive on it a washer, B, which is held in its place on the nut by means of the screw b.
O designates a gimbal-ring, the trunnions cl d of which are diametrically opposite each other, as shown in Fig. 2, and are rounded transversely, so as to oscillate freely in their bearings e e in a saddle, E. This ring 0 is slightly tapered upward and rounded on top, as shown in Fig. 4..
The saddle E has a circular opening through its horizontal portion, in which is loosely applied the gimbal-ring O, which is allowed to rock freely on its trunnion-bearings, and also to swivel freely about the post or hub a, which passes through it, and is provided with the washer B and the retaining-screw b.
The saddle E is formed with three standards, 9 g g, through which passes a riveted pin, on
At the upper termination of the central standard a recess is formed, in which an anti-friction roller, h, is applied, which is free to turn about a piutle, i, driven into the saddle and clinched at both ends.
At It a portionof the saddle E is turned up, and affords a bearing for the attaching-plate A, diametrically opposite the point of hearing afforded by the said anti-friction roller 11.
Vhen the plate A is detached from the other parts of the caster it can be readily secured to the leg of an article of furniture, after which the saddle is applied against said plate, the gimhal-ring is dropped on the post or hub a, and the trunnions of this ring adjusted in their recesses in the saddle. The washer is then applied on its nut on said post or hub, and the whole connected together by means of the center screw, 1).
It will be observed that the out 0 and its washer prevent any liability of the center screw from becoming loose.
The gimbal-ring 0 allows the saddle to oscillate freely, and also to turn about the center post, a, of the attaching-plate A.
I am aware that Letters Patent No. 210,328, dated April 19, 1881, shows a caster having an attaching-plate formed with a post, a saddle having front and rear bearings, forming a species of gimbal, and therefore I do not broadly claim such a combination.
Having described my invention, I claim-- In a caster, the attaching-plate constructed with a prismatic nut on its post a, the saddle provided with a central opening, wheels, and recesses e e, the giinbal-riug 0, provided with trunnions, the washer fitted on said nut, and the central attaching-screw, all combined and arranged substantially as shown and described. In testimony whereof I alfix my signature, in presence of two witnesses, this 17th day of August, 1881. WILLIAM HESSMAN. Witnesses:
JOHN S. LYLE, JAMES B. HUGHES.
v which the wheels G are allowed to turn freely.
