SPECIFICATION forming part of Letters Patent No. 640,201, dated January 2, 1900.

Application filed May 19,1899. Serial No. 717,525. (No modelh To all whom it may concern:

Be it known that I, FREDERIQW. HUNTER, a citizenof the United States, residing at Oranford, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Seats, (Case E,) of which the following is a specification.

The invention is especially applicable to seats for railway and similar vehicles, and will be described herein in that connection. Its object is to produce a seat consisting of but few parts, which shall be simple and durable in construction, inexpensive of manufacture, and which shall be easily and readily adjustable.

The invention concerns more particularly that type of seats occupying a fixed position,

and in which-the seat-cushion and seat-back are adjusted or rearranged accordingly as the seat is designed to face one way or the other.

It further concerns that class of seats of the type mentioned in which mechanism is provided intermediate of the back and seat cushion, whereby the movement of the former produces a corresponding movement of the latter. In seats of this class the seat-cushion is adapted for lateral adjustment in order that in one or the other position of these seat elements each will bear to the other the proper relation.

In carrying out my invention I employ a frame and a movable cushion supported thereby. I also employ a seat-back provided with downwardly-extended supporting-arms pivoted at their lower ends to the floor or the lower portion of the frame. Intermediate of said supporting-arms and of' said movable cushion I employ mechanism for shifting the latter upon the movement of the former. In the present instance this mechanism consists of a pivoted lever at each end of the seat. The lower end of each of these levers is connected, directly or indirectly, with the backsupporting arms, while the upper end of each coacts through suitable gearing with the under side of the cushion. This coaction is secured in the present instance by forming the upper ends of the pivoted levers into toothed segments, and these are arranged to cooper- The upper ends of the members A A are preferably flanged inwardly at ato form a groove in which operates the flanged supportin g member?) of the cushion or cushion-frame B. 'Said cushion has transverse movement upon the seat-frame.

O designates the seat-back. This is mounted upon downwardly-extended supportingarms D, here shown as pivoted at their lower ends to the ends of the rod 01, forming part of the frame and extending through the members A A.

E designates the foot-rest. This is here shown as consisting of a rod or pipe extend ing between and connected at its ends to the supportingarms D. It operates through elongated slots a, formed in the member's'A A of the frame.

F F designate the seat-shifting levers. Each of these is pivoted at f to the frame. The lower end of each lever is provided with an elongated slot f, through which extends the foot-rest E. Thenpper end of each lever F is segmental in form and provided with the toothed periphery f This periphery is concentric with the pivot f, and the teeth thereon engage with the teeth formed in the tracks f secured to the under side of the cushion or cushion-frame B.

In Fig. 1 the seat is illustrated in one of its two positions. To reverse it, it is only necessary to move the back 0 to the right, there-' by of course moving the foot-rest E in the same direction. This movement of the footrest carries the lower end of the seat-shifting levers F to the right and their upper ends to the left, whereby through the gearing described the seat is shifted laterally to the left.

Having now described my invention, what I claim is 1. In a seat, the combination with a frame and movable cushion, of a seat-back, pivoted supporting-arms therefor, and pivoted levers, the lower ends of which are connected to and operate with said arms, their upper ends being provided with gearing coacting with corresponding gearing secured to said cushion or cushion-frame, substantially as described.

2. In a seat, the combination with a frame and movable cushion, of a seat-back, pivoted supporting-arms therefor, a foot-rest extendin g between and connecting said pivoted arms, pivoted cushion-shifting levers having slotted lower ends engaging with said foot-rest, and toothed upper ends engaging with correspondingly-toothed tracks on the under side of said seat, substantially as described.

3. In a seat, the combination with a frame and movable cushion, of a seat-back, pivoted supporting-arms therefor, a foot-rest extending between and connecting said arms and operating through slots in said frame, and pivoted cushion-shiftin g levers provided at their lower ends with slots through which said footrest extends, and at their upper ends with segmental gears adapted to coact with tracks upon the underside of said cushion, substantially as described.

This specification signed and witnessed this 10th day of May, 1899.

FREDERIO WV. HUNTER.
