LOCOMOTIV SPECIFICATION forming part of Letters Application filed January 19, 1897.

To all whom it petty concern:

Be it known that 1, WILLIAM A. RANDow, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Locomotive- Cab Seats; 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 appertains to make and use panying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in locomotive-cab-chair seats; and the objects of my invention are, first, to provide a locomotive-cab chair the seat of which is springcushioned; second, to provide a cabchair having a folding seat; third, to provide a cabchair having a folding arm -rest. I attain these objects by the mechanism illustrated and described in the accompanying drawings and specification, in which Figure 1 represents a vertical cross-section of my improved cab-chair, showing the chair in a folded position; Fig. 2, a side elevation of the same attached to the side of a cab and showing the chair in an open position; Fig. 3, a front elevation; Fig. 4,'two fragments in perspective of a pivotal joint of the arm-rest and one of its supports; Fig. 5, a fragment in perspective of the seat-supporting mechanism, and Fig. 6 a fragment in perspective of the lower wall-support and lower end of the chair.

Similarletters and figures of reference refer to similar parts throughout the several views.

Referring to Fig. 1, A designates the seat, and B the arm-rest.

O is a thin metal plate which I secure to the side of the cab by screws the side outlines of the cab being designated by the dotted lines D. To this plate I secure in a vertical position two yoke-shaped strips E and F, at a short distance apart, by rivets G. The ends of these strips are bent at right angles away from the plate. Extending across the under side of the top part of these strips is a strip H, which is held up against them by the top of the springs I and J, which bear against the under side of it. lhese springs rest on the piece comprise a rigid frame.

E-CAB SEAT.

Patent NO. 582,799, dated May 18, 1897.

Serial No. 619,798. (No model.)

quently this cross-strip is free to move down and compress the springs independent of the vertical strips and of the plate. The ends of this cross-strip are bent down and are riveted with the top ends of the cross-braces M and N to the side standards 0 and P, the bottom ends of which are riveted to the lower ends of the cross-braces M and N. Consequently the standards, the cross-braces, and the cross- On the lower end of the standards I place staples Q, which fit loosely, and secure them to a plate R, which is also secured to the side of the cab by screws S. To the turned-down ends U of the cross-piece H, I secure an angle-plate V, one to each vertical end, by screws W, (see Fig. 4,) and to these angle-plates I rivet vertical strips X, and to the tops of these strips I secure by rivets hinge-pieces Y, which are provided with a T-slot Z or eye, in which fits a T-shaped pin 1, which is formed on the end of the straps 2. These strips are secured to a strip of wood B, which forms an arm-rest. The form of the pins 1 is such that they must be inserted in the eyes before they are secured to the arm-rest, and when the arm-rest is swung down in a position of use the straps rest on the top of the vertical strips X and hold it at right angles to the vertical strips X, as shown in Fig. 2.

In the tops of the standards 0 and P, I formslots 4:, and in these slots I pivot to slide freely up and down angled levers 5 and 6, which support the strip of wood A,which forms the seat, the seat being secured to them by rivets 8. In the lower edge of these angled levers I form a slot 9 in which I pivot one end of a forked lever 10, the opposite end of which is pivoted to the lower end of the standards and the cross-braces,the ends of these cross-braces being carried under and bent up on the opposite side of the standards to form a shoe. The forked lever 10 is formed of the pieces 11 and 12, the piece 11 being riveted to the piece 12 near its lower end. The plate R is secured to the side of the cab in a position to stand about two or three inches above the floor-line D. All of the mechanism of the chair except these plates and the vertical strips E and F are supported by the springs, and when the seat is not in use it is folded up, as shown in Fig. 1, which is accomplished by moving the rear end of the seat or its angled levers up in the slots in the standards and moving the forked levers 10 in toward the standards until they stand parallel with them. The arm-rest may also be moved into a vertical position. hen the seat is to be used, it is swung out, as shown in Fig. 2, by moving the angled seat-levers down in the slots in the standards and the levers 10 out to the ends of the slots in the lower edges of the angled levers. The arm-rest is also swung down to a position of use, and when the seat is occupied the entire weight of the occupant is carried by the springs, which makes a resilient cushion at all times independent of the jolting of the locomotive. The seat is preferably situated in the cab relative to the eab-window to allow the arm-rest to swing down over the window-sill, which is designated by the dotted line 13. IVhen the window is open, by this arrangement the seat occupies but very little space along the side of the cab, and it provides for the engineer and fireman a comfortable spring-cushioned seat and arm-rest of simple and durable construction. Both the seat and arm-rest may be upholstered, if desired.

I do not wish to be limited to the exact construction shown and described, as many changes might be made without departing from the spirit of my invention.

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

1. In a locomotive-cab seat the combination of the side standards the main supportingplate and foot plates, verticallyarranged yoke-shaped strips secured to said main plate, eompression-springs secured to said vertical yoke-shaped strips and secured against displacement therefrom, a cross-strip arranged to rest freely on the top of said springs and adapted to be held resiliently against the U11- der side of the top of the vertical yoke-shaped strips by said springs, with a seat pivotally secured to said cross-piece and adapted to swing downward and upward into vertical and horizontal positions and an arm-rest adapted to be supported by said cross-piece and springs, and adapted to pivotally swing into vertical and horizontal positions, substantially as described.

2. The combination with the supportingplates of the springs, the cross-strip resting thereon, the cross-braces and the oppositelydisposed standards secured to said cross-stri p and having slots in their top ends, angled 1evers pivoted to move in said slots and supporting a seat, slots in said angled levers and levers pivoted at one end in said slots to move therein and pivoted at their opposite ends to the bottom of the said standards and crossbraces, substantially as described.

3. The combination of the supportingplates, the springs the cross-piece resting on said springs, the standards, the seat-supporting angled levers, the seat, the lovers extending from said seatsupporting levers to the bot-tom of said standards, the cross-braces and the vertical strips secured to said crosspiece, a hinge-eye secured to the top of said vertical strips and an arm-rest having a hinge pin and strap pivoted to said hinge-eye and adapted to swing from a horizontal to a vertical position, substantially as described.

In testimony whereof I aifix my signature in presence of two witnesses.

WILLIAM A. RANDOW.
