CAR-SEAT.

SPECIFICATION forming part of Letters Patent No. 580,576, dated April 13, 1897. Application filed September 30, 1896- Serial No. 607,385. (No model.)

To all whom it may concern:

Be it known that I, HENRY S. HALE, of the city and county of Philadelphia and State of Pennsylvania, have invented an Improvement in Car-Seats, of which the following is a specification.

My invention relates to car-seats; and it consists of the improvements which are hereinafter described and claimed and which are shown in the accompanying drawings.

A part of my improvement relates to the employment of a shifting footrest, which, when the seat is reversed by the shifting of the back from one side to the other, is shifted so as to assume a position at the rear of the seat to support the feet of the passenger in the next seat in the rear. The foot-rest shifts or rocks entirely from one side to the other, and the advantage of this construction is that the front portion of the seat below the cushion is always open and unobstructed, thus affording ample space for placing bags and packages which cannot now be stored under the seat owing to the presence of the footrests. Another advantage of this construction is that the space under the seat is left open, so that the floor may be easily swept and cleaned.

Another part of my invention relates to the shifting seat-cushion, and embraces improvements whereby the seat-cushion during the commencement of its shifting movement is bodily lowered. The advantage of this construction is that the shifting seat-back may be brought close to the surface of the seatcushion when in either extreme position, so that the objectionable space or opening in the rear of the seat is avoided. Heretofore it has been necessary to elevate the lower edge of the seat-back above the surface of the cushion in order to enable the seat-back to clear the seat-cushion as it swings over it, and this resulted in the formation of a space or opening between the back and cushion, through which small articles were liable to slip, to the annoyance and inconvenience of the passengers. By the employment of suitable camguides between the main frame and seatcushion [effect the lowering of the cushion as it is shifted, thus enabling the back to clear itwithout the necessity of raising the edge of the back and forming the opening or space.

'vention.

My invention also embraces other improvements and combination of parts, which are hereinafter described and claimed.

Figure 1 is a longitudinal vertical sectional View of a railway-car seat embodying my in- Fig. 2 is a transverse vertical sec= tional view of the same on the line 00 m of Fig. 1. Fig. 3 is a transverse vertical sectional view similar to Fig. 2, showing the seat-back, foot-rest, and cushion in intermediate or halfshifted positions. Fig. 4 is a vertical sectional view on the line y g of Fig. 3. Fig. 5 is an enlarged front view of part of the shifting mechanism, and Fig. 6 is an end view of the same.

A is the main seat-frame.

B is the shifting seat-back.

O is the seat-cnshi-on.

D are the shifting side arms which carry the seat-back. As shown, these side arms D consist of metal castings provided on their lower ends with segmental racks D, which engage pinions E on a longitudinal shaft E, journaled in the main seat-frame. As the seat-back is shifted from one side to the other the segmental racks D travel on the teeth of the pinions E, which they rotate. The side arms D are provided with curved guides d, which engage curved tongues d on the side frames A, and thus serve to guide the side arms and hold them steady.

Lugs 19 b on the side arms strike stops b b on the extremities of theseat-frame, and thus limit the movement of the side arms and seatback in either direction.

The seat-cushion C is carried by a shifting frame F, provided with cam-faces which rest and move 011 guides H H, carried'by the main frames A. The frame F is provided with angular racks I, which engage pinions J on the shaft E, so that when the seat-back is shifted and the shaft E is rotated by the action of segments D on the pinions E the pinion J will.

act upon the racks I and shift the frame F and cushion C. The cam-faces G of the frame F moving on the bars H II will at the same time thatthe frame is shifted tilt it, as indicated in dotted lines in Fig. 2.

So far as the car-seat has been described it is shown in my application for Letters Patent,

Serial No. 552,796, filed June 14, 1895, and

has been shown and described for the purseat-back is shifted.

pose of explaining my improvements, which I shall now describe particularly.

The Shifting Foot-Rest.

K is a longitudinalbar constituting the footrest located under the seat adjacent to the floor and carried by rocking armsL L, journaled on studs 1 or otherwise in the main frame. Carried by the arms L L are upwardlyextending toothed segments M M, engaging the pinions on the shaft E. I haveshown the segments M engaging the pinions J J, which are sufficiently elongated to receive both the segments M and the racks I of the frame of the seat-cushion. The segments M are shown arranged between the pinions E and the racks I, so that the construction may be compact and the segments shall not interfere in any way with the shifting of the frame F.

Thesegments M and arms L are so disposed with relation to the other operative parts that they will occupy an extreme position when the seat-back is in either extreme position,

with the bar K thrown toward the back of the seat, as .in Fig. 2. The foot-rest is then in position tosupport the feet of the persons sitting in the next seat in the rear, while the entire space below the front of the seat is open and unobstructed. \Vhen the seat-back is shifted from the right to the left in Fig. 2, the rotation of the shaft E through the segments D and pinions IE will rock the segments M and cause the arms L and back to swing to the other extreme position on the left, which is then the back of the seat.

As the movements of the bar K are controlled by the rotation of the shaft E, and as that shaft can only rotate when the seat-back is shifted, the bar K will be held locked in either extreme position by the seat-back and side arms D and'can only be moved when the I The weight of the seatback and side arms will offer sufficient resistance to prevent the movement of the bar K and the shifting of the seat-back by the pressure of the foot.

NVhile I have shown the shifting foot-rest combined with the shifting side arms D, which operate the shaft E through the racks D and pinions E, I do not mean to limit my invention to this combination. So far as the shifting foot-rest is concerned it may be employed with other forms of shifting or reversing devicesand my invention comprehends,broadly, the combination of a shifting foot-rest adapted to move bodily from one side of the seat to the other with a shifting part, (either seatback or seatcushion,) by the shifting of which the foot-rest is moved through any suitable connecting mechanism.

The Devices for Shifting the Seat Cushion.

tween the back and cushion, through which 7 articles may slip. As the seat-back must occupy a substantially upright position and in shifting is moved for a short distance only, the are described by the lower edge of the seat-back has so little curvature that the lower edge will not clear the surface of the cushion if it is in contact with the seat-cushion in either extreme position.

To enable the seat-back to clear the cushion, it has heretofore been customary to elevate it above the cushion, thus forming the objectionable opening in the back of the seat. To avoid this defect and to enable the edge of the seat back and cushion to be close together in either extreme position, I employ means to lower the seat-cushion while the seat-back is being shifted over it and to elevate itagain when the seat-back is shifted. These movements are imparted to the seat-cushion by means of the cams which it carries-and which move over the guides H. These cams are shown upon the frames F, which carry the seat-cushion and incline upwardly, as at g g, at each end and then downwardly, as at g g, the inclines g g acting :on the guide H on one side and the inclines g g on the guide on the other side. These inclines are so arranged that when theseat is in the extreme position, as shown in Fig. '2, the high portion of the cam g on one side will be resting on one guide II and the high portion of the cam g on the other side will be resting-on the other guide. This will obviously elevate the seat at both back and front, and as the inclines g g are longer than the inclines g g the seat will be thrown intothe tilted position shown. As the seat is shifted toward the right the incline gtrave'ls upon the guide II, and as that incline tapers upwardly the rear of the seat will :be lowered. At the same time the incline g 'travels upon the other guide II and lowers the seatat the outer end also, and these movements continue until .the seat-cushion is in the intermediate position, (shown in Fig. 3,) at which time the lowest portions of the inclines g 'g .'are resting on the supports H, and consequently the seat-cushion is in its lowest position, so that the seat-back may pass freely over it. As the shifting of the seat -cushion continues the cams g g move upon the guides II II andelevate the seat-cushion into exactly the opposite position of that shown in Fig. .2, with the opposite edge of the seat-cushion close to the lower edge of the seat back. So far as this part of my invention is concerned it is obvious that the particular form of devices used for shifting the seat-back and moving thecushion on the guides II H is not material, and any suitable'mechanism may be used for that purpose instead of the particular devices shown, as this part of my invention is equally adapted to any carseat employing a shifting seatcushion.

For the purpose of guiding and steadying the seat cushion in its movements the side with lugs to, between which and shoulder h on the cross bars H the cam frames F are guided in their movements on the guides H.

As the seat back, cushion, and foot-rest move together it is necessary that the proper positions of these parts with reference to one another should be insured. Otherwise they will not occupy the proper relative positions when the car-seat is in use. If the parts are assembled in the proper relative positions, they will necessarily maintain those positions, and to insure the assembling of the parts in proper relation to one another I form each of the racks D, M, and I with an enlarged cent-ral tooth or recess (Z m, and 2', adapted to engage correspondingly-enlarged teeth or recesses e and j in the pinions E and J. These teeth and recesses are so disposed that when the arms D are in the central position (shown in Fig. 3) the teeth d will engage the recesses e and the teeth j of the pinions J will engage the central recesses m andz'in racks I and segments M, so that the seat cushion O and footrest K will occupy a central position corresponding with that of the arms D and back B.

The working parts may thus be easily as sembled together without the possibility of any part being out of proper position with re lation to any other part.

To support the arms D upon the frame when in either extreme position,I provide them with lugs f, adapted to engage lugs on the ends of the side frames.

The various detailsof construction which have been shown for purposes of illustration may be varied without departing from the invention.

\Vhat I claim as new, and desire to secure by Letters Patent, is-
