BACK-REST.

SPECIFICATION formingpart of Letters Patent No. 271,944, dated February 6 1883. Application filed August 17, 1882. (No model.)

' To all whom z'tmoty concern.-

Be it known that I, ALBERT W. STREEPER, of Fairbury, in the county of Livingston and State of Illinois, have invented certain new and useful Improvements in Back-Rests; and I' do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to an improvement in back-rests, and is adapted more particularly for use on shoe-makers benches, seats for sul kyplows, and other agricultural implements, the object of the same being to provide an attachment whereby a person can either sit upright or in a reclining position, and have a firm support for the hack throughout its entire length; and with these ends in view my invention consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying draWings Figure 1 is a side view of my improvement, and Fig. 2 is a rear view of the same.

A represents a shoe-makers bench, plow, or

similar seat, and B the back-rest, pivotally secured thereto in such a manner as to automaticall y adjust itself to the changes of position of the user.

0 is an angle-iron, the arm a of which is rigidly secured to the under side of the seat A by the screws b, while the vertical arm, a, which is situated atright angles to the arm a, is rigidly secured to the leaf 0 of the hinge D by welding, riveting, screws, or. in any other suitable manner. The other leaf, 0, of the hinge D is secured tothe back-rest B. by screws, and is as long as the back-rest is wide, which serves to strengthen the parts and prevent the said rest from warping. Instead of making this leaf 0 the length described, a wooden cleat can be. secured to the back of the rest, and a hinge of the ordinary construction be employed, which will answer the necessary purposes.

The hingeD is so situated on the back-rest that a portion of the users back rests above the hinge and a portion below it, When the user sits erect the rest B also follows his movement and assumes a vertical position, and when he leans backward or reclines the rest is caused to assume aninclined position. The

.amount of inclination of the restB is, how ever, limited by the headed stud E, which latter is rigidly secured to the back-rest B. The shank of the said stud passes through a perforation in the leaf 0 of the hinge D, and through a registering-perforation in the arm a of the angle-iron C, while the head d, which is larger than the said openings or perforations, rests on the outside of the arm a. This construction allows the upper end of the backrest B to be tilted backward until the head at of the stud abuts against the arm a, which inclination is sufficient for the purposes in view.

My invention is. simple in construction, is of few parts, can be manufactured at a small initial cost, and can be readily attached to any sort of a seat without the aid of skilled labor.

It is evident that slight changes in the construction and relative arrangement of the different parts might be resorted to without departing from the spirit of my invention, and hence I would have it understood that I do not limit myself to the exact construction shown and described, but consider myself at liberty to make such changes and alterations as come within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

V 1. The combination, with the seat-bottom A, having the angle-iron secured thereto, of the back-rest B, hinge D, one leaf of which is secured to the back-rest between its upper and lower ends, and the other leaf is secured to the upright portion of the angle-iron, sub stantially as set forth.

2. The combination, with the seat-bottom A, having the angle-iron secured thereto, of the back-rest B, hinge D, secured to the back-rest and angle-iron, andthe stop (1, located below i the hinge and extending through the angleiron, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two'subscribin g witnesses.
