Application filed March is, 19217. serial: no. 453,325.

in Car Seats, of which the following. is a speciiication.

My invention relates to railway car sea-tsv and my object is to provide a seatv whichf willbe.V light oft weight, by which maximum 1 cushion-space will bel secured for a gimenv over-all length and l in which a minimum number o'fp arts will be used. afin. additional object is to provide a construction' in whichf a minimum of space'at the ends of the seats is taken npwith mechanism or frame-work..

A further object of this invention is v to provide a seat which'fmay' be manufactured and assembled inexpensively and easilyandat the same time i'sverydu-rable and efficient in operation.

@ther objects will be in part obvious in part pointedout hereinafter: A

My invention relates particularly toA the typev of seat such` asis disclosed inthe ap,- plieation of George. l/V.. Dryer, carv seat, Serial` Number' 8525342, filed January 19,122.05 although many' features of my invention may readily beyemployed withl other types of seats.

The type of seat above referred. to comprises twor pairs of supports,.pivoted on op:- posite sidesof the construction, each. pair supporting a member adapted toV beA posi'- tioned` either as a seat on as back. @ne `of these members isv pivoted at the front and the' other' at the back of the construction, and connections areprovided between the two membersy such that when one rests inseating position the other will ezotendnp wardly;T from' its pivot in the correct-position to serve as a back. When it isdesired tore.-

an d

verse the seatingtdirection of the seat the member which is serving-*as a backmay be swung' downwardly about its. pivot into po.- sition to serve as a sea-ttthe other member rising at the same time from itsseating vposition into position to serveas a back at the opposite side of the .construct1on.. The connection between'the seat and back members comprises a pair of links, onerat eachend ofthe construction, which links are pivotal-ly connected at their endsto the end surfaces of the seat and back membersatpoints above the pivotal connections. between said members and their supports. The function of these links is to canse a memberin seating position to swing upwa fd into backposition whenv the other member swings doWIlwar-d1 from back position into sea-tino` positiont and arfurther function to prevent either'l member from swinging rearwardly beyond its correct back position or forwardly therefrom when the seat is occupied.

lt has been found that by fashioning these links in a shape resemblingsomewhat an l elongated crescent instead of in the shape of a compound cur-ve, asV has heretofore been the custom7 not only will asmaller space be re,- Cpiired at the ends of the seat for the movement of theselinks and thereb7 considerable additional space at the ends ofV the seat is conserve@ but the ends of the linksmay be. connected with the seat and back members at points further from their points of pivotal support,V and by the increased leverage thus obtained the seat' and back members may be more easily shifted from one posi-l tion. to the .other when desiredT and these members 'are more positively held .against undesired. movement when in extreme position.

Moreover, `in accordance withA invention l provide vnovel andi improved means for mountingthe seat and back members on the construction by providing channel irons secured to each end of jthe back andV seat members, and. improved( means for mounting these channel irons on the supports as well as improved connections between the links and these channel irons.. Asa result a very efficient construction is obtained and one which is inexpensive to manufacture', comprises a minimum of parts and one which may` be easily assembled yor taken apart for: the replacement of parts. Also the parts arey not apt to work loose.

In order that a clearer understa-ndingy of my invention may be had, attention is hereby directed to the accompanying drawings forming a part of this application and illustrating one embodiment of my invention. In the drawings Fig. l represents an end elevation of a construction .embodying my invention; Fig. 2 is a front elevation of a part of one side of the construction; Figs. 3 and 4 are sections taken respectively on the lines 3`3 and 4-4 of Fig. 1.

Referring to the drawings, a suitable support, such as a pedestal 1, is provided and two angular members 2 are mounted on the support, one at each end of the seat. Seat and

back members

3 and 4, respectively, which may be substantially duplicatesof each other, are each adapted to serve either as seat or backcushions and are pivotally supported on members 2, one on each side of the seat. Extending along each end of these

members

8 and 4 1 provide a supporting standard comprising a channel iron 5 adapt-` ed to receive substantially the entire end of the member between its flanges 6, and having its web perforated so that it may be atl tached to the back or seat member as by means of screws 7. At their lower ends these back-supporting members 8 are pivotally supported on the seat-ends 2 so as to permit the seat or back member supported thereby l to be easily swung about this pivot and-at the same time be positively supported on the end plates 2. As shown in Fig. 4 the particular means for pivoting these standards to the end vplates 2 may comprise a lug or ear 8 on the lower end of the standard 5 and a' perforation 9 therein, an annular ring 10 positioned through perforation 9 and having an annular flange 11 resting against the inner side of the standard 5, a bushing 12 within member 10, having an annular liange 13 over-lapping flange 11 as shown, andcontaining a threaded perforation 14 adapted to receive a screw 15 threaded therein through an opening 16 in the end plate 2 with the head of the screw bearing against said plate 2. The assembling of these parts will provide a bearing for the channel iron 5, as shown, and it is readily apparent that byA assembling the parts as above described the screw 13 will not be rotated when the supporting standard 5 is swung on its pivot to effect the reversing of the seat. With this construction the parts are not apt to work loose and fall apart and a very yefficient and suitable pivotal connection is provided for the back and seat members.

The link members connecting the back and seat members comprise a link at each end of the seat, as at 17, extending between the two back and seat members, and each link is pivoted at one end to one of the standards 5 and at its opposite end to the opposite standard of the other member. As shown, the links 17 comprise a straight, horizontal, central portion and upwardly extending portions 1S at each end. The ends of these links are perforated as at 19 where they are pivotally connected to the respective standards 5 well above the points at which the standards are pivotally connected to the end plates 2. Referring to Fig. 3 it is seen that a perforation 20 is supplied in the channel iron 5 above its point of support on end plate 2, and in this perforation 1 seat an annular ring 21 having a liange 22. 1n this annular ring 1 position a bushing 23 having links 17 and willnot be apt to become dis lodged during the operation of the seat.

The links 17 are of such length-and the points of their

pivotal connectionto members

3 and 4 are so chosen that when member 3 rests in seating position, member 4 is in the correct position to act as a back-cushion, and when member 4 `rests in-seating position member 3 will be in correct position to act as a back-cushion at the opposite side of the structure, this position being indicated in dot and dash lines at the left of Figure 1. A. rubber pad 28 or other suitable support may be provided for the

members

3 and 4 to rest'upon, when in seating position.

By forming the links with a longitudinallyextending, horizontal, central por-V tion upturned atv the ends, the links are adaptedto be conned to a minimum space during the reversing movements of the seat.y The upturned ends permity connection of the links to the back and seat members well above the points at which these members are connected to the seat ends 2, and the increased leverage thus obtained will render it4 easier to effect a reversal of the seat in response to pressure applied Vto the member then positioned as a back.

The intermediate positions of members 3; and 4 on the reversal of the direction of the seat` are indicated in dotted lines in Fiiirel. Y p ith the construction illustrated, the vertical movement of links 17 is very slight and these links may be readily maintained completely masked by the seat ends 2. The construction described makes an extremely light structure possible with a very slight space requirement for mechanism at each end of the seat; requires a minimum of parts; and the construction of the pivotal connections is such that the connections are not apt to work loose and theparts are not apt to become loosened or displaced.

The Aparticular form of seat and backcushion -to be used is not material for the present'invention and istherefore not illuscushion.

Members

3 and 4 may be, for eX- ample, of Wooden slat construction, double paneled or they may be otherwise formed and shaped With suitable upholstery, if desired.

What I claim is:

l. In a car seat, thecombination of supports, a pair of similar seat and back members pivotally secured to said supports at opposite sides thereof and a horizontally disposed link having a straight, central portion .and an upwardly extending portion at each end, pivotally connected at its respective ends to said seat and back members substantially above the connection between said .members and said supports.

2. ln a car seat, the combination of supports, a pair of similar members pivotally secured to said sup-ports at opposite sides thereof and each adapted to be positioned as a seat when the other is positioned as a back, and means for causing the movement of one member from seat to back position automatically in consequence of the movement of the other from back to seat position due to pressure applied to either member,

said means comprising va link vhaving a straight, horizontally-extending, central portion and an upturned portion at each end and pivotally connected at its ends to said similar members.

3. In a device of the character described, in combination, two members and means for pivotally connecting said members together, said means comprising a perforation in one of said members, an annular ring positioned in said perforation and having an annular flange overlapping the periphery thereof, a bushing seated Within said ring and having an annular flange overlapping one end thereof, a threaded perforation in said bushing, a perforation in said other member registering with the perforation in said bushing and a screw having a head over lapping said other member and a shank eX- tending through said perforation in said member and engaging the threads of said bushing.

This specification signed and witnessed this 11th day of March, 1921.
