Application filed May 19. 1905. Serial No. 261,180.

To all whom it may concern.-

Be it known that we, EDWARD G. BUDD and States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and' useful Imlow-ing is a specification.

The object of the present invention is to provide a car-seat structure of the walkover type possessing great strength and durability, the moving parts thereof, including theback and for shifting the seat-cushion, being characterized by positive mechanical coaction.

A further object of the invention is to provide means whereby the back reversing and guiding mechanism may be relieved of a large portion of the weight of the back, such.

supports forming part of the stationary seat structure.

In carrying out the invention we employ a walk-over seat-back mounted (detachably or tend downward for coaction with sto s carried by the seat-frame. Coacting wit these back-supporting arms at each side are twolevers pivoted centrally of the seat-frame and at their other ends pivotally connected with one of such back-arms, the latter pivotal points being in the longitudinal center of such back-arm. At the points of pivotal connection of said levers and the seat-frame we employ positively-coacting mechanism between such levers, whereby the movement of reversal of the seat-back is made smooth and continuous, lost motion is avoided, and ease of operation in changing the seat from This mechanism. will be pointed out in detail hereinafter.

The invention is illustrated in the accompanying drawings, in which Figure 1. is a side elevation of a car-seat embodyingour invention, showing, however, one of the end frame-plates removed to exas seat and back cushions, supporting-frame,

&c. Fig. 7 is a section on the line 7 7, Fig. 6 and Fig. 8 is 'an enlarged perspective view illustrating the coacting mechanism intermediate of the ends of the levers shown inFig. 6.

Referring first to Figsfl to 5, inclusive, it will be seen that the structure here'illustrated includes a supporting frame or pedestal A and sills or rails- 1. extending between and connecting the same, said sills or rails supporting rockers B, carrying seat-cushion C. It is contemplated that the seat sup orting and reversing mechanism at each en of the seat shall be the same in construction, although, as is well understood in this art, this may not be observed in practice as, for instance, the mechanism at the aisle end ofthe structure may be that hereinafter-described, that at the wall'end of the car being of such a character as not t-o interfere with theoperation or sacrifice the advantages of the mechanismat such aisle end. We shall therefore describe in detail only the mechanism at one end of the seat structure. Supported in any suitableimannerupon the seat support or pedestal'iAis an inner end plate D, the side edges cl whereof .are flanged outwardly at an angle to the body portion thereof, as clearly shown in Fig. 3. E E designate stops, here shown as cor-uprising straps or bearing-pieces of right-angular cross-section, the lower webs e whereof are riveted or otherwise secured to the plate D and then per webs e whereof form shelves to repeive tlie back-su porting arm hereinafter described. Rivete secured uponthe webs e are buffers, which may be of wood or of several thicknesses of leather, as desired. These bufi'ers receive the impact of one of the back-supporting armswhen the latter assumes operative position iii either of the facing directions of the seat.

pose the back supporting and-reversing mechanism. Fig. 2 is a(-,entralcrosssection. Fig. 3 is a plan view on the line 3 3, Fig. I, illustrating the back supporting and guidingi F designates the walk-over seat-back, here 1 shown as provided with a socket f, with which engages thefback-supporting arm f, havin the foot f 2 coacting with one or the other of l I v l or otherwise the steps above described. G H designate, respectively, the u men and lower backguiding levers, the iormer of which is pivoted at one end g to the l')ackarm f" and at its other end upona stud g, extending through and journaled in the inner end plate D. The backuiding lever H is pivoted at one end h to t e back-armj" and at its other end is supported upon a collar h, keyed or otherwise secured to. said lever H and extending through the inner end plate D, where it is secured, by key or other means, to the tie-rod 1, extending between and connecting the movement at one end of the seat with that at the other in order to synchrol'iize the operation of such movements. As clearly shown in Fig. 3, the .lower' enlarged ends olf the levers (irH lie in the same vertical plane.- Each of said levers, however, is provided with a" shoulder (marked g g", respectivel v,) whereby such levers intermediattot' the shoulders and the pivotal points 1 h are se )arated from each other -by a substantial tlistance, enabling them to clear each other in their movement from one position to the other and in addition to permit the pivotal point of the lever (.i to be on one side of the back-arm f and the pivotal point It upon the. other, as illustrated in Fig. 1. L designates a check-block secured by screws 1 to a stud 1. extending through the inner end plate l and provided outside the same with enlarged head 1", said check-block being thus supported on said inner end plate in such manner as to permit the same to oscillate under the inlluei'ice ol' the levers (r ll, as presently eX- plained. Said chcck-block is provided with oppositely-arranged semicircular cut-away portions 5 1;, and on either side of the cutaway portion with substantially straight portions If and on either side of the. eut away portion 1" with substantially straight portions Z If. The lever G is provided with wings g on either side of its pivotal point g, and carried by each of these wings and between such wings and the inner end plate l) is a stud g" 9 sired configuration, but we prel'cr to make them in the lorm of round pins cut away at their sideedges in parallel planes, as illustrated in Fig.5. The lever ll is also provided with wings h h", and these wings also are provided with studs in 11., which may, if desired, be similar to the studs g g. The studs g g and the studs h If coact with the oscillating check-block 11 in such manner as that by means of such check-block the back-guiding levers G H shall at all times be mechanically:

interrelated, whereby the movement of the back from one to the other lacing direction of the :at' is made uniform and continuous and lost. motion avoided. 'lhis positivemechani ul interrelation will readily be understood from Fig. 5 of the drawings. illustrating the seat parts in the position shown in Fig. 2.

'lhese studs may he of any dc-.

l I l Here the stud g of the lever G and the stud h of the lever H. are in coaction with the sen'iicircular cutaway )ortions l l, respectively, of the .checklock L. In the movement of the back from the Fig. 2 position to the Fig. 1 position the stud g rides up the curved side of the cut-away ortion Z until it escapes therefrom. At tie moment of such escape the stud g comes into coaction with the substantially straight portion Z on the other side ol the cut-away portion 1 of the check-block. During the movemei'it as thus far traced the action of the stud 71 ol the lever 11 is substantially the same as that of the stud q of the lever G, and the action oi" the stud it of the lever H is substantially the same as that of the stud g ol' the lever (i. It now the movement be continued, so that the back-arm f and the levers (r and [I shall lie in truly vertical and pa rallel planes, t he stedsg g ofthelever Gwill both coact with the substantially straight portions! at the upper edge of the checkblock ll, and the studs It it? will coact with the similar portions 1 t atthe loweredge of the check-block l1 and the turned on its pivot. The movement being continued so as to bring the back to the Fig. 1 position, the stud g rides along the substantiall straight portion to the right, and the stud escapes from the substantially straight. portion at the other side of the check-block and enters the cut-away portion 1, remaining in contact with the edge of such cut-away portion. This action is true also of the studs 1:" if of the lever H. It will thus be seen that the lower ends of the levers G H are, as above stated, at all times in positive mechanical coat-tion, with the advantageous resultabove referred to.-

The plate I) has been herein referred to as the inner end plate, for the reason that we prefer to employ two parallel end plates at each end of the seat and in the present disclosure have illustrated, therefore, the outer end plate 1). provided, like the inner plate I), with angularly-llangcd edges d. coacting with the llanged edges d of the inner plate l) and secured thereto, preferably bv means of bolts or screws d Also we prefer to employ tubular struts d, secured upon the inner lace oi the outer end plate. I) and extending between said plate l) and the inner end plate I). Extending through said struts (Z and through the plates l) D are bolts (1, which, together with. the edge bolts bind the two end sections (comprising the plates l) D) lirmly and rigidly together, said bolts preventing the. movmncnt of such plates away from each other and the struts (1 preventing movement thereof toward each other. li as in the con.-.truction now being described, a. seat-cushion ol the shifting type be employed, the movement ol' this. coextensively with that of the back, may be accomplished by means of a lever M, keyed or m'entof the back .Ltransmits corresponding movement to the seat-cushionby way ofthe lever H, tie-rod I, lever M, and rocker B.

- In Figs. 6,7, and 8 we have illustrated a modification of the, construction abo've de- -scribed,'this involving the use. of mechanism serving the same purposeof positively correlating the leversttGfjH in. said figures) not only in} their ultimate oositions, but also durand the stud H with the slot n.

peazthe imene ing their; n10 venie nt om-one of such positionsto the .other. The intermediate checkblock here takes circular form as shown at N, and isprovidedwith the slots n n and the raised portion a, the edges of the latter being cut away at n n it, and n to form what we term dwells forcoaction with the round ends ofthel evers Said checkblock ispiv-otaLl-v. as shown at rn main (circular) ortion thereofunder-ly h H evers fir/{Hf andgthe dw sate n lying in the same plane as s i ,llds of said levers. The lever G is prov' 'led with a stud G beyond the point atwhich saidlever is pivot.

ally-secured to the end plate andlying be tween said lever and said end plate. The lever H is provided with a similar stud H intermediate of the two pivotal points of said leverand between said lever and said end plates. The stud G coacts with the slot n As clearly shown in Fig. 6, a portion of the rounded end of each of thelevers G H is in coaction with one of the dwells upon the raised portion 11/. As the back is moved. to the left this coaction continues until the studs G H enter their coacting slots in the check-block N, when said check-block is rotated upon its pivot a". As the movement is continued and the studs G H ride out of their coacting slots the curved edge of each of the levers on the opposite side comes into coaction with one of the dwells upon the raised portion n, thus maintaining the lower ends of said levers G H in positive mechanical coaction at all times, including, as above stated, not only the ultimate positions of the back, but also during the movement of said back intermediate of such positions.
