' Specification of Letters Patent.

Patented May 23, 1916.

Application filed January 24, 1913. Serial naveasss.

To all whom it may concern Be it known that I, RIoPIARD B. MARSH,

a citizen of the United States, residing at Philadelphia, in the county of Philadelphla and State of Pennsylvania, have invented certain new and useful Improvements in Car-Seats, of which the following is a speciseat-cushion in reversing the facing direction of the seat.

The object of the invention is to provide a cushion-moving vmechanism of this character which, while being simple in construction, possessing great strength and being capable of manufacture at low cost, will occupy but little space and, particularly,

will extend downwardly from the seatcushion'but a small amount.

In the construction of seats for use in railway cars, it is desirable that the maXimum space be provided belowthe seatcushion, and this is particularly true with respect to the space at the end of acar-seat adjacent to the wall of the car, for it is common to utilize this space for the steam pipes which run lengthwise of the car and form part of the heating system of the car. In many forms of car-seats as heretofore made, the space under the seat-cushion at the wall end of the seat has not beenas great as has been desired because of the space required for the mechanism by which the seat-cushion is moved when the back is reversed. In accordance with the present invention, the seat-moving mechanism is so constructed and arranged that it does notencroach upon the space under the seatcushion and below the supporting structure Referring to these drawings, the car-seat is shown as consisting of a back-cushion 4 and a seat-cushion 5, these being mounted upon a suitable supporting structure including a pedestal 6, a seat-end 7 and two connecting rails 8. In the present instance the pedestal 6 is shown as constructed of sheetmetal, and the Seat-end 7 is shown as integral with one of the parts of the pedestal. The back-cushions is mounted upon backsupporting arms 9, each of which is adapted to travel upon an arc-shaped rail 10 which is secured to the inner side of the seat-end 7. In this way the back-cushion may be moved from one edge of the seat-cushion to the other to reverse the facing direction of the seat. The back-supporting arm 9 has a slot 11 therein which receives a pin on one end of a lever 12 which is secured to a rock-shaft 13, mounted in bearings formed in the seat-ends. When the back-cushion is moved from one position to the other, the shaft 13 is rocked in its bearings by means of the levers 12. This rock-shaft serves to connect the mechanisms at the two ends of the seat so as to insure synchronous movement of the parts at both ends and, furthermore, the movement of the rock-shaft is utilized to cause the shifting of the seat-cushion.

A support 1 1 is provided between two connecting rails 8, this support being in the form of a sheet-metal strip having its ends bolted or riveted tothe rails 8. This support forms a track upon which a member of the seat-moving mechanism is adapted to be reciprocated. This member is here shown as a block 15 which rests upon the strip 14: and is provided with headed studs 16 extending through a slot 17 in the strip 14. The block 15 is provided with a vertically-disposed way or groove '18 in one side thereof which is adapted to receive a stud or projection 19 formed on the end of a crank arm 20 which is secured to the rock-shaft 13. Thus, when the rock-shaft is rocked in its bearings, the crank arm 20 will causethe block 15 to be moved in a straight line upon the surface of the strip 14.

The block 15 has a lever 21 pivotally mounted thereon, the lever 21 being on the side of the block opposite the crank arm 20. At one end this lever 21 is provided with a stud 22 which enters a vertically-disposed slot 23 in a rocker 2 1. This rocker is supported upon the connecting rails 8 and forms 1 the support for theseat-cushion 5, the rocker being provided with pins 25 which enter cp'emngs in the frame oftheseat-cushion.

lhe lever 21 is provide'dlwitha slot in'the" end thereof opposite that on which the pin cushion is moved from one edge to the other of the seat-cusl1ion,.the T rock-shaft 13 "is" rocked in'its bearingsand as a result of this I rocking movement the block 15 is moved in a; straight lineovje'r the surface ofthe support 1 4; This'movement'ofthe block 15 causes a shiftingof'the pivot of'the lever 21. At the same time that this shifting ofthe pivot of the lever 21 takes place, that lever is caused to turn about its pivot, for one end of the lever' is in 'coa ction with the rock-7' shaft'13. The opposite end of the lever 21, that is. the end'which is connected to the" rocker 21, is therefore given a movement resulting in part I'romthe lateral shifting of the pivot of lever 21, and in part from the movement of the lever about its pivot. In this way the requisite-amount of movement of the rocker 24 is obtained even though the lever 21 is quite short. By reference to the 'for 'movement of the back-cushion.

drawings, and particularly to Fig. 2, it will be seen tha't'the mechanism for effecting the shifting of the'seat-cushion as the back- Cushion is reversed is very compactly arranged. As here shown, none of the parts of this seat-moving mechanism extends below'the plane of the lower edges of the connecting rails. As a result of this all of the space below the connecting rails is available for other uses, and particularly for the steam pipes employed in heatingthe car.

i It is 'to beunderstood that various modificationsmay be made in the construction hereinlillustratedand described, without departing from the invention, and that all such modifications I aimrto include within the terms of the appended claims." Particularly, I wish it understood that the invention is, not limited with respect to the type of mechanism by which the back-cushion is supported and by which provisionis made The mechanism herein shown for this purpose is chosen merelyv to illustrate a mechanism which will serve this purpose and which may be employed in connection with myimproved seat-moving mechanism. a
