WALK-OVER CAR-SEAT.

SPECIFICATION forming part of Letters Patent No. 784,426, dated March '7, 1905.

Application filed September 9, 1903. Serial No. 172,432.

To (all whom it may concern: 2

Be it known that 1, CHARLES K. PIokLns, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in alk-Over Car-Seats, of which the following is a specification.

Heretofore seats of this type have been made with. a plurality of links at each end of the seat by means of which the back has been brought over the seat-cushion to reverse the seat.

The object of my invention is to simplify this construction by utilizing only one link at each end of the seat and also to provide mechanism which cooperates with said links to shift the seat-cushion in unison with the back. My invention accomplishes this and other objects.

For a more particular description of certain embodiments of my invention reference is to be had to the accompanying drawings, forming a part hereof, in which* Figure 1 is an end elevation of a seat provided with my improvement, the end plate being removed to show the mechanism. Fig. 2 is a front elevation of the same, a part being shown in sections. Fig. 3 is a plan view of the end of the seat next the stanchion. Fig. 4 shows a part of the mechanism in perspective. Figs. 5 and 6 show in perspective a slightly-modified structure. Fig. 7 shows one form of seat-support. Fig. 8 discloses one face of an end plate used in the structure illustrated in Fig. 4. Figs. 9 and 10 show a further modification, and Figs. 11, 12, 13, and 14 show certain details connected with the same. Figs. and 16 show another modification. Fig. 17 shows a shaft-connecting mechanism.

Throughout the various views similar reference characters designate similar parts.

lVhile my improvement may be utilized in many forms of car-seats, I will show and describe a form which is particularly adapted to convertible cars with a central aisle and transverse seats. In this structure one end of the seat is supported by a panel 1 and the other end by any suitable legs 2, and the panel and legs are united by foot-rests 3 and tubular cross-bars 4, which extend from sockets 5 in the panel 1 through adjustable sockets 6 at the upper extremity of the legs 2, and these cross-bars 4 may be clamped in place by these sockets by cap-screws 7. The said cross-bars 4 do not terminate at the sockets 6, but extend beyond them to the inner end of the seat, where their ends rest in sockets 8 on the end plate 9, and to this plate they are fixed. The plate 9 may be given any suitable shape, although it is preferably made, as shown,\vith seats 10 on its upper edge and sockets l1 and 12, which are centrally located between the sockets 8 and on the same side of the plate. The other side of this plate 9 is provided with a strengthening-flange 13 and may be given any suitable ornamentation. Instead of the seats 10 (shown in Figs. 5 and 6) stops 14 and 15 may be employed, as shown in Fig. 4, as either obtains substantially the same results.

Parallel shafts 16 and 17 are journaled in the sockets 11 and 12 and also in similarlydisposed sockets 18 and 19 in the panel 1, so that said shafts may revolve freely. These sockets 1S and 19 are 'n'eferably formed in a flanged angle-plate which has a lower vertical web 20, in which the cross-bars 4 are fixed in sockets 5, and an upper horizontal Web 22, which is provided with a recess 23, through which stanchion 24 passes. A lug 25 on the outer part 26 of the panel 1 supports a part of the web 22. The web 20 is fixed to the part 26 by cap-screws 27 or other suitable means.

The rotary shafts 16 and 17 are each provided with cranks 28 with crank-pins 29, which engage a connecting-link 30, so that the shafts 16 and 17 will always turn together and in unison. These shafts are also provided with eccentrics 30 and 31 adjacent to 32 are each provided with two openings 33 and 34, the former being on the eccentric 30 and closely fitting the same, while the latter is elongated enough to permit the eccentric 31 to turn freely therein. The upper surfaces of the brackets 32 are adapted to receive and support a cushion 35, so that this cushion Will always be properly inclined with regard to the back 36.

At each end of the back 36 are plates 37 and 38, with oppositely-disposed projections 39 and 40, which are provided with pins 41, which are engaged by links 42, which are fixed to the shafts 16 and 17, respectively, adjacent to the plate 9 and vertical web 20. The links 42 are vertically disposed-that is, they swing in a vertical plane, a structure which is altogether different from one in which they swing in a horizontal plane, asis apparent. In themodification shown in Figs. 5 and 6 the plates 37 and 38 are provided with additional projections 43, which are adapted to rest in the seats to limit the movement or swing of the back 36. The same result is accomplished by the stops 14 and 15, which the links 42 rest against at the limits of their movement. These links are preferably flanged and provided with recesses 44 to enable them to clear the shafts 16 and 17. The back 36 is also provided with a hand-strap 45, which is secured to a staple 46, secured at its upper and inner edge, as is apparent from Fig. 2.

As the walk-over back is somedistance from the stanchion 24, a guard is advisable, so I provide two links '47 and 48, the latter of which issmaller and is pivoted to the stanchion 24 at 49 and at its other end is pivoted to the .link 47 at 50. This link 47 may be given any suitable form and is pivoted to the back 36 at 51. Another form of guard is shown in Fig. 15, in which the'link 48 is dispensed with. The link 47 is made longer than the link 47 and provided with an enlongated slot 47 through which a pin 52 protrudes to secure the link 47 to the stanchion 24 with a sliding and pivotal connection. The other end of the link 47 is secured to the back 36 by a pivotal connection. The seat may be provided with either of these guards, or they may be omitted entirely, as desired.

From the foregoing the operation of this embodiment of my invention will be readily understood. Assuming the parts to be in the position indicated in Fig. 1, the seat is reversed by swinging the back 36 on the links 42, which will be caused to move in unison and rock the shafts 16 and 17, with their eccentrics and 31, and shift the brackets 32 and seat 35, as described above, until the movement of the links is terminated by the stops 14 and 15 or by the contact of the projections 43 with the seats 10. The guard swings on its pivots or its pivot and slide, as is apparent.

It is not necessary that the cushion be supported on the brackets 32, as these may be replaced by rockers 53, which rest on the crossbars 4. These rockers 53 each comprise two vertical webs 54, unitedby curbed and horizontally-disposed webs 55 and 56, and the web 55 is extended to form rests 57 with lugs 58 for the cushion, andv these rests 57 are united with the Web 56 by earns 59. The web 56 is also provided with depending lugs or guides 60. The opening between the webs 54, 55, and 56 is sufficiently large to allow the shafts 16 and 17 to pass freely therethrough and not interfere with the movement of the rockers 53, and the cranks 28, which are fixed to said shafts, are so disposed that their connectinglinks 30 will each have a lug 3O engaging the guides 60 and cause the said rockers to slide on their cams 59 on the bars 4 and tilt and shift the cushion 35 in unison with the back 36 when the seat is reversed.

A simpler construction with a fixed seatcushion is shown in Figs. 15 and 16, in which the cushion 35 is fixed to the seat-panel and legs 2, and the rotary shafts 16 and 17 are mounted in hangers 61, which are fixed to the under surface of the cushion 35, and stops 62 for the links 42 are also secured to the cushion, as the plates 9 and rails 4 are not used in this structure.

It is obvious that my improved mechanism for shifting the back may be used either with or without the seat-shifting mechanism or the guard, as described above, and on seats extending either entirely or partially across the car. It may also be used when the outer ends of the seats are between the stanchions or on any other structure when walk-over seats are applicable. For these reasons I do not regard my invention as restricted to the embodiments herein described, but regard it as applicable to all structures which come within the terms of the annexed claims.
