tir-frein rrrrnnr sie CLARENCE L. THOMPSON, OF PORT VJASI-IINGTON, N EVT YORK, ASSIG'NOR TO HALEI ANID` KILBURN COMPANY, OF DELAWARE.

To all whom t may concern: Y

Be it known that I, CLARENCE L. THOMP- soN, a citizen of the United States, residing at Port lvashington, in the county of Nassau and State of New York, have invented certain new and useful Improvements. in Car-Seats, of which the following is a specification.

My invention relates to railway car-seats of the reversible-back type, and comprises a structure having numerous points of novelty and advantage in comparison with the existing types of car-seat. Briefly, it may be stated that my improved construction is adapted to be formed entirely of steel, as to its metallic parts, the structure therefor being much lighter and stronger than seats of malleable or cast viron construction. providing 'maximum cushion length for theA over-all length of the seat, the construction being such as to permit the seat-cushion to extend a greater distance toward the aisle and wall plates thanV has been possible with other mechanisms in the past, while at the same time the spaces between the ends of the seat-cushion and the adjacent aisle and wall plates, in which the striker-arms usually move, and in w-hich there was always the danger of al passengers clothing being zanght, are done away with. All the mechanism for moving the seat as the back is reversed is located beneath the seat in exceedingly compact 1 form, al novel type of rocker and i'ecker-opcrating mechanism being provided, which results in various advantages which will be pointed Vout hereinafter. The rockers, it may be stated, ai'e operated preferably by means of an eccentric or cam mechanism and what may be'termed a i collapsing lever7 from the backstandards,

Y resulting in a short forward-and-back oscillation of the rocker over the cross-rails onwhieh the rocker is supported, the necessary reversal of the seating inclination of the seat being. accomplished wiah a short forwardand-back movement of the seat, insufficient to cause lthe seat-cushion to project beyond the ends of the aisleand wall plates, in which projected positions the seat-cushion is in the It also accomplishes the purpose `of PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF CAR-SEAT.

wayA Vof a passenger entering the seat.' The' arrangement of seat-operating mechanisml doesaway with' the necessity for slotting the back-supporting standards, whereby the latter may be strongly and economicallyfmade.;

In my preferred construction, the' cross-rails of the seat are made of tubular section and secured to the wall and aisleplates by slipping the ends of thetubes over' short stubs or ferrules onthe lwall vand aisle plates, the rails being held in place by means of cotterpins or the like. By this means, the' construction is made muchmore economical',

strong and light than in previous constructions, vvhile 'the danger of loosening bolts etc. is obviated.

The objects of my invention are" the provision of the improved Vconstructional vfeatures above briefly referred to and others jliereinafter more fully described, which are combined to form my improved devices.

In orderl that a clearer understanding of I my invention may be had, attention is hereby directed to the accompanying drawings, forming part ofV this application and illus'- trating certain embodiments of my invention. InA these' drawings,l Figure l repre-v sents anend elevation of a seat embodying my invention; Fig. 2 is a front elevation of the same; Figs. 3 and 4L are verticalsectxons taken on lines 8 3 and 4.-4- ofV Fig. 2, re- Y spectively; F ig. 5 is a partial plan view of the seat-operating mechanism, certain parts being shown in horizontal section; Fig. tl is' a vertical section taken on line 0 6 of Fig.

5; and Fig. 7 is an enlargedhorizontal section, showing the connection between a tubular cross-rail and rock-shaft and one of the end-plates.

Referring to the drawings, the cross-rails y aisle-plate.

which it is seen that short ferrules or stubshafts 5 are secured to the walland aisleplates and the tubular rails 1 slipped over the same, the cross-rails and stubs being secured together' by any simple suitable means, such as the cotter-pins 6. Each short stub or ferrule 5 may be secured to the adjacent plate in any suitable manner, as by securing the same to a flanged collar which is suitably secured to the wallor By the provision of tubular rails, 1 gain both in cheapness and strenf in comparison with the solid rails of anginar section commonly used, while the use o' the ferrules or stub-shafts with Cotter-pins provides connection with the walland aisle-plates of a. simple and efficient charac' ter, which insures the proper alinement of the cross-rails without any difliculty, while at the same time the use of bolts, which are apt to work loose, is done away with. riihc tubular rails Vform bearing surfaces for the rockers, as will be hereinafter described.

The seat-cushion 8 is mounted upon

theV rockers

9, 9, which latter bear upon the tubular rails 1, 1, as stated. rlhe back-cushion 10 is carried by a pair of standards 11, 11, which standards carry rollers, 12, at their lower ends, on the outer sides of the same, these rollers being mounted in the channeltracks 13. Tracks 18 are the usual curved channel-tracks formed on the inner faces of the aisleand wall-plates, rollers 12 traveling through the same, in theusual manner, when the back is reversed.

tandards 11 are secured, as by screws 14C, to the ends of the back-cushion, and are each formed with an offset portion 15 to enable the standard to clear the end of the seatcushion. The standard is bent inwardly underneath the seat, as shown at 1.6, from which point it extends downwardly to its lower end, which is provided with the rollers referred tO.

' A pivot-pin for operating the rocker mechanism extends a considerable distance lengthwise of the seat from the inner face of each standard, the seat-cushion considerably over-hanging the rocker-operating mechanism at both ends. The desired position of the pivot-pin referred to is prefer-V ably arranged by me, by securing a strap 17,

bent in box section, to the inner face of the standard, pivot-pin 18 extending inwardly, lengthwise of the seat, from the web or inner face 19 of the boX structure 17 referred to. The mechanism for operating the seat is entirely below the same, as stated, and by the arrangement ileseribed l am enabled to prolong the seat S into close proximity to thc standards lland the aisleand wall-plates, practically no space being left between the endsof the seat and the aisleand wallplates, except that necessary for the move- Vversed from theV position shown in Fi -ln'ans 22, '22,' being provided at the outer ends of guides-21, 21, these horns being inwai-diy directed lengthwise ofthe rocher. lVhen the standards and the back-cushion are inY their right-hand,position, referring to Fig. 3, the seat-cushion is supported with its left end elevated slightly, the right-hand rail 1 being under the iight-hand or upper edge of flange 20, with horn 22 below the same, while the left-hand rail 1 is at the right o; lower end of the flange 20, which rests upon the same. Villien the position of the baclris reversed, the rockers are moved over the rails 1, into the reverse position, with the left-hand rail 1, referring to Fig. 3, above the horn corresponding thereto, the seat-cushion being then inclined in thev opposite direction and moved sidewise a short distance corresponding to the opposite positions of rails 1 with respect to guides 21.

Y rlhe roclrers are preferably operated by cam or eccentric movements, as stated. 1n the drawings, each rocker is provided, at a position intermediate the cross-rails 1, 1, with a ring 23, mounted for rotation between the upper semi-circular flange Zei formed on the rocker, and a curved bearing strap 25 pivoted at 26 to the rocher and adapted to be secured at its opposite end at 27 to the rocker to form the lower bearing therefor. The tubular rockor eccentricshaft QS is secured eccentrically within the outer' annulus n3 of each eccentric. The ends of tubular shaft 28 are rotatably supported on stub-shafts or ferrules 28", on the end-plates, similar to stub-shafts 5 to which cross-rails 1 are secured. lli-lever 29 is secured to tubular shaft QS, adjacent each end of the same, each lever-member Q9 being formed with a longitudinally slotted guideway 30 therein in which `the male levermeniber 31 is adapted to slide. Sliding member 31 is provided with a lengthwise slot 3Q, in which the pivot-pin 1S of standard 11 is adapted to move. The sideportions of member 29 are slotted, as shown at 232%, in, alincinent with slot S2, to accommodate pivot-pin 1S when member 31 is telescopcd within member 29. YWhen the back is and it t the drawings, tubular rock-sha1 and eccentric 23 are oscillated, lever-niembei' 31 sliding doiv-n into. lever-member 29 as the standard .passesover thefcenter, and being drawn out again as the standard approaches the opposite side ofthe seat, the inclination of the seat being reversed as ,described.

In the movement described of the collapsing levers 29-31, the latter travel in slots 34 inthe frame ofthe seat-cushion, these slots conveniently being spaced between'the usual transverse slots of the cushion-frame. The spacing of the collapsing levers in line with these spaces-or slots is conveniently ai'` ranged by having the pivot-pins 18 extend inwardly a considerable distance from the standards l1, as described. The box-section base 17 for pin 18 provides a strong structure for this purpose. By the arrangement described the usual striker-arm having a pivot-pin mounted in a slot in standard 11 is eliminated, whereby the lengthof the seat is increased, as'stated. Also by the elimination of the slots in the standards 11, the latter can be made stronger and be manufactured more cheaply and efficiently.

It is obvious that my invention is not strictly limited to the exact details of construction described, my invention being apprehended to be as broad as is indicated by the accompanying claims'. The various constructional features and movements described coact to produce the desired advantageous results referred to, but various of the portions of my invention described may be used without the others, in'the form described, with advantageous results.

Having now described my invention, what I claim as new therein and desire to secure by Letters Patent is y 1. In a car-seat, the combination of a pair of cross-rails and supports for the same, a reversible back, supporting standards therefor, a seat, rockers supporting said seat and mounted for oscillatory movement on said rails, said rockers each having a circular opening therethrough with a semi-circular lupper flange, a curved bearing strap pivoted at one end to the rocker and adapted to be secured to the rocker at its opposite end to form the lower bearing for said opening, said rockers having curved lower bearing surfaces contacting said rails, a rock-shaft parallel to said rails, extending eccentrically through the openings in said rockers, rings secured on said shaft mounted for rotation within said openings, between said upperV thereof, rockers supporting the saine, a backsupporti-ng standard, movable past said seat cushion, and connections between said standard and rockers for operating the ,latter as the lback is, reversed, comprising a lever mounted in a vertical plane, beneath said cushion, connected to operate said rockers and connected to said standard by a pin and slotjconiliection, the pin of which extends under said seat-cushion, said lever being movable in said `slot in the seat-cushion frame, substantially as set forth.
