Application filed. August 10, 1915. Serial No. 44,674.

To all whom it may concern:

Be it known that I, RICHARD l3. MARSH,

a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Car-Seats, of which the following is a specification.

My invention relates to improvements in 19 railway car seats of the type in which the back is movable across the seat and operates through suitable connections to rock the latter, when the back is reversed, to reverse the seating inclination of the seat-cushion.

My improvements have to do chiefly with the connections between the back and seatcushions, improved results being attained by novel combinations and arrangements of elements. The back-supporting standards carry rollers which are mounted on channel tracks, which latter, however, are not secured directly to the wall and aisle end plates, but are supported directly upon the cross rails, underneath the respective ends of the seat-cushion. Also, the channel tracks referred to do not face inwardly, as they do in usual practice when secured to the inner faces of the end plates, but face outwardly. The result of this is that the back-supporting standards pass closely adjacent to the ends of the seat-cushion with their rollers extending inwardly, beneath the seat-cushion into the channel tracks, the levers by which the seat-supporting rockers are operated from the movements of the standards being located on the outer sides of the standards instead of on the inner sides as formerly. The result of the altered positioning of the elements referred to is that to the seat-cushion is given a maximum length in relation to the overall length of the seat,

the construction permitting the seat-cushion to extend a greater distance toward the wall and aisle plates than has been possible with 4a mechanisms previously used. All mechanism is removed from the aisle and wall plates except the bearings for the rock-shaft by which the rockers are operated. Also, since practically no space remains between 50 the ends of the seat-cushion and the respective end plates, except that necessary for the movements of the standards, the danger of a passengers clothing or the like, catching in the spaces referred to is greatly de- 55 creased.

In my preferred construction, tubular cross rails are employed, to which the channel tracks are secured by means of small brackets, preferably drop forgings, mounted on the cross rails. Preferably, each rocker is supported by a steel bracket riveted to the adjacent channel track. The channel track at the aisle end may be positioned substantially above the pedestal which supports that end of the cross rails; by this construction the various strains on the rocker and standard are transmitted directly through the channel track, forged bracket, cross rails and pedestal, so that there is practically a straight line connection between the back and the floor of the car. Therefore e'xtreme strains on the cross rails, such as are produced when the pressure on the back is transmitted to the aisle plate and thence laterally along the connecting rails to the pedestal, are eliminated. Another improved result of my construction consists in the fact that parts thereof may be made as a complete unit in the shop, via, the track, the bracket on the track to which the rocker is pivoted, the rocker itself, and the two brackets by which the track is secured to the cross rails. These various elements are combined in one unit, before shipping, the construction thus permitting improved shipping conditions and a simple and economical as sembly of the complete seat.

Other objects of my invention are the provision of improved portions of the mechanism, such as the rocker movement.

In order that a clearer understanding of my invention may be had, attention is hereby directed to the accompanying drawings forming part of this application and illus trating certain embodiments of my invention.

In the drawings, Figure 1 represents an end elevation of a seat, provided with my invention, Fig. 2 is a front elevation of the same, Fig. 3 is a vertical section taken on line 33 of Fig. 2, to an enlarged scale, Fig. 41 is a top plan view of the mechanism shown in Fig. 3, Fig. 5 is a longitudinal vertical section taken on line 5-5 of Fig. 3, Fig. 6 is an end elevation of a seat having a somewhat diiferent rocker movement, Fig. 7 is a front elevation of the same, Fig. 8 is a cross-section on line 88 of Fig. 7, Fig. 9 is a top plan view corresponding to Fig. 8,

and Fig. 10 is a longitudinal vertical section on line 1010 of Fig. 6.

Referring first to Figs. 1 to 5 of the drawings, the cross rails 1, 1, preferably tubular in cross-section, are illustrated in the drawings as supported at their inner ends by the wall plate 2 and adjacent to their outer ends by the pedestal 3, it being obvious that a similar pedestal might be employed at the wall end of the seat if desired. The seatcushion 4L is supported by

rockers

5, 5, and back cushion 6 is supported by

standards

7, 7 carrying

rollers

8, 8 extending from the inner faces of the standards, and resting upon the lower flanges of the curved channel tracks 9, 9. An aisle end plate 10, similar to the wall end plate 2, is carried by the outer ends of the tubular cross rails 1, 1. As stated, aisle end plate 10 does not support any of the mechanism, except the rockshaft hereinafter referred to, and accordingly can be made quite light, being a mere cover plate. Each channel track 9 is mounted with its top and bottom flanges faced outwardly, that is the track at the aisle end faces the aisle and the track at the wall end faces the wall, the tracks being located beneath or partly beneath the respective ends of the seat-cushion 4. Each channel track 9 is supported by a pair of

brackets

11, 11 from the cross rails l, 1, these brackets preferably being drop forgings, each having a vertical Web portion riveted or otherwise secured to the vertical web 9 of the channel track. Each bracket is provided with a horizontally curved bearing portion 11 which rests upon a cross rail 1, these hearing portions 11 being secured to the cross rails by means of bolts 12.

Preferably, each rocker 5 is supported by a pressed steel bracket 13, which is provided with a central portion 13 of channel shape riveted to the web 9 of the channel track, as shown at 14. Bracket 13 is provided with an upwardly extending portion 13 above the channel shaped portion 13 and an upwardly extending portion 5 of the rocker is pivoted thereto by a pin 15, the

portions

5 and 13 of the rocker and bracket extending upwardly in aspace or slot in the frame of the. seat-cushion, this space suitably being a space between the cross slats of the seat-cushion frame. By this means a pivotal point is provided for the rocker at a considerable distance above the bottom edge of the seat cushion.

The rocker is preferably operated by eccentric means. As illustrated, rock-shaft 16 is rotatably supported in the bearings formed on the two end plates and a pair of eccentrics 17 17 are secured thereon. Each eccentric is rotatably mounted within the jaws 5 of its rocker. A lever 18 has a boss 18 secured to rock-shaft 16, lever 18 having at its upper end a pin 19 adapted to play in the slot 20 of standard 7. It is evident that the rockers and seat-cushion are held in position by the engagement of eccentric 17 in the rocker and the connection therefrom to the standard when the back is in one of its positions of rest, and that the eccentrics, and accordingly the rockers, will be rocked when the back is reversed, the 1 eccentrics moving around the rock-shaft to reverse the seating inclination of the seat.

It may be noted that levers 18 are positioned on the outer sides of the standards within the flanges, such as 10, of the end plates, the pins 19 therefor extending inwardly from the levers into the slots in the standards, as also the rollers 8 extend inwardly from the standards into the channel tracks, the word inwardly being understood as signifying the direction from either end of the seat lengthwise thereof, toward the central portion of the seat-cushion, and the word outwardly the reverse. By the arrangement described, the seat-cushion is permitted to extend outwardly some distance beyond the back-cushion into close proximity to the standards 7 which move closely adjacent to the end plates, it being understood that the standards are outwardly offset in the usual manner to permit the same to clear the ends of the seat cushion. Each channel track 9, together with its supporting brackets 11, the rocker supporting bracket 13, together with its rocker 5, may be assembled together in the manufacturing establishment as a unitary construction as stated.

The construction illustrated in Figs. 6 to 10 inclusive differs from that already explained chiefly in the use of a different form of rocker. Each rocker 5 is arranged to have its bearing on the tubular rails l, 1, the lower surfaces of each rocker being formed with a compound curve comprising lower bearing portions 5 and upper bearing portions 5. The eccentrics 17 are secured upon rock-shaft 16, within the jaws of the rockers, and connected by levers 18 with the standards 7, in the same manner as described in connection with the first species of my invention. When the back is in one end position, the rockers rest, with surfaces 5"" at one end and surfaces 5 atthe other end contacting the cross rails, the rockers sliding to the reversed position when the eccentrics are operated by the reversal of the back.

It is obvious that my invention is not limited strictly to the exact details of construction described herein, but is as broad as is indicated in the appended claims.
