To all 'whom l may eoocerrfz.:
it known Ethat l, EDWARD G. Brum, e citizen. et 'the United State, residing et Pliiledelpliis, ir: 'the county of Fhiladelphie. and State ol" Pennsylvania., have invested certain new and uselul lmproveroeiits in Cor- Seats, of which the following is sy specilieetion. A
This imfentioo. concerns cer-seats end ses reference, more particularly, to the medien ism for supporting' the seet-lmel the proper ongle of inclination permitting reversal tliei'eoi' from one edge oi the cushion to the otlier sud lor simulteueouslyv shifting tl'ie seet-erisliion to reise its forward edge stove .its rearward edge.
The obviect ol" the invention is to so improve the meeli emisor for supporting the parts and reversing tl'ie facing direction of csr-seats ol the Walkover type es 'ro pro vide e. compact meclrsuisrii which possesses maximum strength, wliicli is so constructed that Compsrativeljv smell force is require-d to reverse the seat, and by which the beek is held positively' against an im xroper moverrient throughout the reversal thereof and in the desired relation in its l'inel positions.
My improvements ere of particular utility in ireproor' seats in wliieli all the' parts are mede ol irietel except 'for tlie coverings of the cushions.
l lieve illustrated the preferred embodiment of my invention in the, eooiripenyirig dra-wings, in which Figure l is sri elevation of the aisle-end of 'the seat, Fig. 2 is en enlarged transverse seotiorr of e portion of the end of the seat es shown in Fig. l', Fig. 3 is en elevation of the operating' mechanism et the eislefend of the seirt es seen from the inner side, end Fig. 4 .is a top View one of the rockers for the seetcushion.
The drawings illus rete only the mechanism for the aisle-end of the seet but tliet at the ull-'end nie-'y be substantially vthe seme es that slxowii, tl'rougli preferably, it is supported ori the well ol the csr instead of the 'Hooi'.
R' the sont is supported ou in, metzrllio cricket consisting; ol two substantially similer ports, esi-cli lowing o liodjV l und e leg 2, the adjeoent of tlie former being secured to` retirer sud the erids oi the letter being secured 'to tlie vliloor. At its upper end, this Ierrlug to the d1mvings,.tlie`aisle-end of cricket is provided with integra-l sriges on which are secured the ends or two com-lectin rails S. To the ende of these mils ere liolt e' end connectors or sockets Il toiwhieli is 'seeured s remeplete 5. This plete formed to provide e eem surface oft peculiar oorifformation for supporting and guiding e beeksupperting erm es lie 'eine-iter described; this preferably done by cutting e, slot in the, plete the ro 'or portion, @,Fof Wh'loli is formed ori an are of large radius sud et the erids of the portion 6 site dormWsrdlyF-exteudirrg end portions 7 oud At the lower edge olf the portion. of the slot md et equal distantes from tlie ends 7 sind S are two rounded eut- :r 'portions 9 endl G. ivotel'ly mounted upon the inner side ol plate ere one or more rollers Whose upper surfaces ere sulistenti'sy ilusli. 'with the lower edge of the slot in tlie plate; in the drawings, ,l have shown two suoli, rollers 1l mounted between and Close to the offsets 9 and 1G of the slot.
The slot iu plate 5 is adapted to receive and guide two rollers l2 and 13 pivotally moi-mted on alle lower erid of e beck-supporting erm le which moves backend fortl'i. adjacent to the plete 5. This erm extends upward and is seeured at its upper end to the beekousllioir 27 of the seat, a socket-plete l5 being secured over 'the upper end ol" erm lll. The lower end of arnoY lll is of eonsidereble width and the roll l2 and 13 thereon are et e distance apart equal tothe distance be tween either end of the slot in plete 5 :md the oifset 9 or l() adjacent thereto.
ln the plete 5 is e central opening termin a bearing for the end of e. rod 16 and seoure on this rod is s lever 1'2". The end of this lever extends up adjacent to erro 14l arid is provided with o, pin .1.8 Wlilcli extends through en elongated slot in erm lll. This piu hes en enlarged head to prevent the pin rom slipping through the slot, this heed lieiiig flattened on opposite sides to permit of readily assembling end disassemblirlg the parts.' Below the rod i6, lever 17 is bent iu 'Wordly of the seet and its lower end is provided with e segmental gear 19. This gear meshes with e rack ZO on the rocker 21 for the sent-cushion 22. Rooker 2l is mounted to slide beek and forth in rooker-runslormed in the sockets or end ooriiiectors Il and on its lower edge. lies oem surfaces Wliioli serve to alter the angular relation o?? the rocker es it mores lu the welter-runs. 0n its upper to enter holes in the 1.3 lying in the cutaway portion 10.
edge, the rocker has dowelpins 24 adapted under side of the seatcushion trarne to support the cushion and move it as the rockers are moved.
In Fig, 4, a top view of the rocker 21 is shown, om which it will be seen that the teeth of the rack 20 are separately formed and project from the side ofthe rocker vso that dust cannot settle in and partially ll the spaces between them and prevent smooth working of the parts.
A cover-plate 25 of metal is secured in any suitable manner on the outer side of plate 5 over the slot therein and serves to hold the parts of the plate against relative movement under the strains to which they are subjected. A seat-end 26 is secured to plate 5 to conceal the operating mechanism and extends upward above the plane of the seatcushion, its upper edge supporting an armrest. This seat-end is preferably formed of sheet-metal and is of attractive design.
The operation of the seat as thus constructed will now be described.
-In the position of the parts shown in Figs'. 1 and 3, the back 27 is supported by the rollers 12 and 13 on the back-supporting arm 14 bearing on the cam surface formed by the lower edge of the slot in plate 5, the roller 12 lying -at the bottom of the down- Wardlyeturned end portion 8 and the roller The back is held at the proper inclination with relation to the vertical as the roller 13 is above the roller 12. In reversing the facing direction of the seat, force is applied to the back in the horizontal direction. At the beginning of the movement of the back, the rollers 12 and 13-ride up on the lower in clined edges of the end 8 and the oilset 10, respectively, of the slot in plate 5, these edges being arranged to diverge somewhat in the upward direction, and the back is raised slightly and turned angularly to appreach the vertical more closely. When rollers 12 and 13 are in the substantially ilat portion 6 of the slot, the movement ol the back is practically a horizontal one so that very little force is required to move it, this being further decreased by the anti-friction roller or rollers 11 which are engaged by the lower edge of arm 14 and, to a large extent,- take the weight ol' the back oiil rollers 12 and 13. As the back moves along, the coaction of pin 18 with the slot in arm 14 turns lever 17 and the rod 1G to which it is secured, the pin 18 moving to the upper end of the slot and back again to the lower end during the reversal of the back. W hen roller 12 is directly over the o'll'set l() in the slot in'plate 5, there is no downward movement of the back such as would carry the reller into the offset since the-roller 11 adjacent to the oli'- set is in engagement with the bottom of arm 14 and supports the latter. vSimilarly the roller 13 is prevented from moving into oil"- set 9 by the roller 11 adjacent to that offset. l/Vhile the rollers are moving across the portion 6 of the slot, which is, curved on an arc of large radius, the angular relation of the back with reference to the vertical is changed slightly and when roller 13 reaches the end of the portion 6 it moves downto the end ofthe downwardly-turned portion 7 g at the same time, roller 12 moves down to the end of the offset 9 and the back is in its final position.
It will be seen that the sides of the olisets 9 and 10 adjacent to the ends of plate 5 are curved over to form projections indicated at 28, Fig. 3, under which the roller on arm 14 will lie when it is at the bottom of the oliset and the back is in its final position. 'lhe coaction of pin 18 with the slot in arm 14 precludes such movement of the back as will cause roller 12 to lodge on top of the projection 28,' as above stated, pin 18 moves to the top and thenl down again to the bottom of the slot during the reversal of the back and it reaches the lower end as thev roller l2 ap` preaches a position over projection 28, thus down into oil'set .0, and while doing this, pin
. of gear 1Q and rack 2() causes i 18 moves away from the bottom ol 'in arm 1-1 a very slight distance. But when roller 12 is in its final position at the bottom of slot 9, the )rejection 28 extends so far around the roller as to preclude any movement thereol" under the weight ol' lhe occupant of the seat against the bark. 'lhe other roller 13 rests in the bottom of the end portion 7 and therefore the bach is lirmlyr held in its operative position. 'llhe coaction novement ol roc ters 2l and the seat-cushion carried thereby as the backis moved, in a direction opposite to the direction of movement oli the back and the cam surfaces 22% on the rockers' operate to raise the [forward edge of the seat above its rearward edge.- Rod 1l (i to which the levers 17 at both ends ot' the seat are secured serves to synchronize the movements at'hoth ends of the seat.
.lt will be seen that the mechanism ol'` the seat as tlms constructi-*d is verycompactly|` arranged and that on account ol the. shape ol theI slot in plate 5 with the major portion tl'lereol" `curved on an arc ol long radius, the plate can be of com )aratively small width. This shaping ol`- thel slot gives the `further advantage that the back is raised'vertically 'only a small yextent in reversing, andtherefore a small amount ol' vtorce is required to reverse the seat.
llaving now describedV my invention, what I claim new therein and desire tosecure by Letters Patent is as lollows:
1. ln a reversible car-seat, the combination, of a frame, a movable back, a backsupporting arm, a cam. surface on said frame precluding further movement in this direction.
