GEORGE W. HAYES, OF GOSHEN, INDIANA.
BACK- REST.
SPECFCATION forming part of Letters Patent N o. 371,062, dated October 4, 1887.
Serial No. 238,256.
(No model.)
To all whom t may concern:
Beit known that I, GEORGE W. HAYES, a citizen of the United States, and a resident of Goshen, in the county of Elkhart and State of Indiana7 have invented certain new and useful lmprovementsin Back-Rests; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon,whie.h form a part of this specification.
Figure 1 of the drawings is a representation of this invention and is atop view. Fig. 2 is a side view. Fig. 3 is an elevation of a lathe with the rest in position, and Fig. 4 is a section of the same.
The invention relates to improvements in back-rests; and it consists in the construction and novel combination of parts, as hereinafter set forth.
The back-rest commonly used by turners is made with a fork, and either scorches or mars the piece of work being turned.
The object of the invention is to avoid the above, and at the same time perfectly support a long piece when being turned, so as to effectually prevent all swaying and trembling and cause the piece to turn true.
Referring to the drawings, A A designate the lathe-centers, and-B a piece of work being turned between them.
O is a standard rising from the lathe-bench or other propersupportasuitable height, and D is a Y-shaped bar having the shank E, provided with the longitudinal slot e, and the two equal arms F and F', standing at opposite angles from the shank, and provided, respect ively, with the longitudinal slotsf and f.
G is a set-screw having a large milled head, g, or other suitable handle, by means of lwhich the shank E can be secured upon the upper end of the standard at any desired point.
H and H are rods provided with the shoulders 7L, passing through the slots ff', respectively,and having the anti-friction rollers I and I', journaled on their extended portions on one side, and being provided on the end of said portions with collars to retain said rollers. Theopposite ends of the rods are threaded and engaged by the thumbnuts K and K', respectively, by means of which the rods and rollers can be set at any desired points of the slots f andf. Thus the bar D can be set farther in or ont at any angle, to suit different distances from the standard O or different heights, by means of the slotted shank and set-screw G, and the anti-i`riction disks can be set neareror farther apart by means of the rods and thumbscrews to suit different thicknesses of work. The anti-friction rollers, moreover, prevent the work from being marred, scorched, or burned.
Having described myinventiomwhatl claim 1s` In a back-rest, the combination, with the slotted bar supported by the standard C, and the set-screw to secure the bar to the standard, of the rigid diverging arms, the threaded rods passing through slots in said arms, the thumbscrew engaging the threaded ends of said rods, and the anti-friction rollers on the opposite ends of the same, substantially as specified.
In testimony whereof I aiiix my signature in presence of two witnesses.
GEORGE W. HAYES.
