SPECIFECOATION forming part of Letters Patent No. 654,352, dated July 24, 1906. Application filedMay e, 1899. Serial No. 715,803. on, model.)

To all whom it may concern:

Be it known that I,WILLIAM M. NoRoRoss, a citizen of the United States, residing at the cityand county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Oar-Seats, of which the following is a full, clear, and exact description, reference being hadto the ac c'ompanying drawings, forming a part of this specification.

Thisinvention relates to car-seats,and more especially to that class wherein the seat and back sections are so relatively arranged and connected that the latter may be shifted or swung from side to side of the former as oocasion may require and the seat-section at the same time be inclined and forwardly projected in respect to the position of the back.

The invention is in the nature of animprovement on the car-seat set out in my Letters Patent of the United States No. 610,719, datedSeptember 13, 1898, to which reference may be had, my object herein being to afford provisions whereby the said seat maybe con verted into a reclining-chair at the will of the occupant irrespective of the direction the seat may be facing. To that end I combine in a novel and effective manner with the carseat certain leg (or foot) rest sections, which are so mounted and organized with relation to the back that the positions of the sections will be automatically controlled thereby. Thus when the back occupies its usual inclined position relative to the seat (regardless of the direction the seat may be facing) the said rest-sections will be closed or retracted. When the back is further tilted or inclined, the forward section will be projected and elevated to afford the occupant of the seat a convenient leg or foot rest, the elevation of which will be determined by the angle or inclination of the back, and when the back is shifted to the opposite side of the seat and likewise inclined the positions of the rest-sections will be reversed. In thisway a reversible reclining-seat is provided.

Accordingly my invention comprises novel features of construction and organization of parts, which will be hereinafter particularly described and claimed, it being understood that I do not confine myself to the precise mechanism herein shown and described, as

the same may be considerably modified with out departing from the fair spirit of the invention.

In the annexed drawings, Figure 1 is a 1011 gitudinal vertical section, partly in elevation, of a carseat embodying my improvement, the leg-rests being shown in retracted position. Fig. 1 is adetail of a portion of one of. the frame members. Fig. 2 is a view similar to Fig. 1, illustrating the parts in the relative positions they occupy when one of the leg" rests is projected. Fig. 2 is a detail of one of the leg-rest sections and adj uncts. Fig. 3 is a horizontal section as on the line y y of Fig. 2.

1-1 are suitable end frames on which are formed or seen red the

transverse members

2, and 3 are the usual rockers that sustain the seat-section 4. These rockers comprise slides with oppositely beveled or inclined portions 5, that bear upon the fixed socket casings or supports 6 on the frame, whereby when the rockers are slid to and fro they, together with the seat-section, are correspondingly projected and tilted. The rockers are actuated by and during the adjustment of the back-section 7. This section is provided at each end with a depending arm 8, which lies adjacent to the inner side of the frame member and is provided with two studs or projections 9 10, located at points equidistant from the median line of the back and arm. The arm is pivotally' connected at a fixed point thereon below the back-section, as at 11, to the upper end of a lever 12, that is fulcrumed on the frame member, so that as said lever is swung to and fro the back will be bodily lifted and carried thereby from side to side of the seat. The lower arms of the levers on the respective frames are connected by a rod 13, which insures their concerted movement. This rod engages slots or sockets 13 in the respective rockers, and thus during the shifting of the back from side to side reciprocates the rock ers to effect the requisite adjustment and in- I clination of the seat-section.-

On the inner side of each of the frame mem-- bers are two reverse-cams 14 14, With which the studs or projections on the proximate arm are adapted, alternately, to coact as the back is swung from side to side, and thereby positively guide and steady the back in its adjustment, the lower edge of the back being bodily elevated by the lever sufficiently to clear the arched cushion of the seat. The lower extremities of the cams communicate with guideways 15, which extend toward and adjacent to the casings 6 6, respectively, and constitute, in effect, continuations of the respective cams fora purpose below explained. The lower or inner walls of the cams are foreshortened to afford an extended open space or gap on each side of the median line of the seat for the passage below the cams of the rearward stud on the lever as the back is tilted in its traverse. The upper walls of the cams meet about the median line of the seat.- frame, or substantially so, to the end that just before the escape of the rearward stud from the lower wall of the cam with which it is engaged the forward stud will coact with the upper wall of the opposite cam, and thus insure a stable support for the back as it is wun ac oss the' nt r f he t- Adjacent to and parallel with each of the frame members is a bridge-bar 17, that is rigidly aiiixed to the socket-casings or elsewhere on "the end frame. This bar is provided with expanded end portions 18, which afford suitably-located supports for bell-crank levers 19 19, respectively. A corresponding lever and connections therefor are disposed at each end of each of the bridge-bars, as shown, and therefore a description of one lever, with'its connections, will suffice. The longer arm of the leveris pivotally connected with the lower end of a bar 20, on the upper or free end of which is supported one end of a rod 21, that extends parallel with one side of the seat. Th fi rod Connects the two bars 20 at the respective ends of the seat and insures their movement as a unit. On the rod is pivotally supported a section 22, which constitutes a leg-rest, This rest is sustained yieldingly inplace by a torsional spring 23, which, encircling the rod, is secured to the leg-rest and to one Of he end bars. When the rest is projected, (as below described,) the spring maintains the same in horizontal position, or n arly so- Each of the bars 20 is connected with the adjacent end of the bridge-bar by a link 2t, whereby when the crank-lever is properly actuated the leg-rest will be swung downwardly adjacent to the side of the seat or be projected forwardly thereof in position to receive the legs of the occupant.

The lever is actuated through the medium of an inclined push-bar 2 5, the lower end of which is pivotally connected with the shorter arm of the lever, while the upper end extends toward the opposite side of the seat and I is provided with a laterally-disposed stud or projection 26, that is fitted to one of the gnideways 15 in the adjacent frame member.

' There are two leg-rests, one at each side of the seat, These rests are correspondingly supported and operated, the push-bars therefor crossing each other below the seat-section and being connected with the opposite guideways in the frame members. The positions of the leg rests in respect to the seat are controlled by the adjustment or inclination of the back. Normally they occupy the closed or retracted positions represented in Fig. 1, wherein, as will be observed, they, together with the bars and links, occupy a vertical position, and the upper ends of the push-bars are at the respective junctions of the cams and guideways. In this view the seatis shown as facing toward the left, the back being in what may be termed its normal inclined position "-that is, the right-hand stud or projection on the arm 8 is at the bottom of the proximate cam. This stud or projection thus bears against the opposing end of the pushbar which is connected with the forward leg= rest, the vertical position of the latter and its bar and link serving as a temporary lock to prevent, under ordinary conditions, the further rearward inclination of the back. If, however, this leg-rest be sharply pulled out} ward sufficiently to throw the bar and link out of parallelism and rearward pressure be thereupon exerted against the back, the righthand stud or projection on the arm 8 will en: ter the right-hand gnideway, an bearing against the opposed projection on the push: bar, will advance the latter in a manner to project and elevate the forward leg=rest, as seen in Fig. 2. Thus it will be seen'that the occupant of the seat may be leaning back more or less, and at the same time regulating his weight on the legrest, determine the de: gree of inclination of the seat-back and the elevation of the leg-rest. If the back-sece tion be swung to the opposite side of the seat, the left-hand stud on the arm will enter the adjacent guideway and act upon the opposs ing push-bar to project the then-forward legre'st into operative position, the previouslyprojected leg-rest assuming, by gravity, its closed or normal position upon the removal of the opposing stud from the pushebar during the adjustment of the back, I

It will be understood that when the back in its traverse occupies the central or vertical ICC position both studs bear against the upper walls of the respective cams and that as the movement is continued the advancing stud continues in engagement with the upper wall of the cam, while the rearward stud sWiQgs downward below the same, thereby elfectin' g the gradual inclination of the back and per; mitting the engagement of the advancing stud with the guideway at the end of the cam, also, that as the back is swung from side to side the studs coact with the two oppositely-disposed cams in alternate succession.

I claim- 1, In a car-seat, the combination, with the frame and the back, of a depending arm on said back, a lever pivoted to said frame and having a fixed pivotal connection with the arm, a cam connection between said frame and arm, whereby as the back is swung upon the lever from side to side of the seat the back is guided and adjusted in respect to the seat by said pivotal and cam connections, and means whereby the back and its arm when swung to either side of the seat may be tilted rearwardly upon the lever independently of the cam connection.
