AISLE END FOR CAR-SEATS.

Application filed April 12, 1913. Serial No. 760,657.

ToaZZ whom it may concern:

Be it known that T, EDWARD COPELAND LANG, a citizen of the United States, and resident of Melrose, in the county of Middlesex and State of Massachusetts, have in vented certain new and'useful improvements in AisleEnds for Car-Seats, of which the following is a. specification.

This invention has relation to railway car seats.

The object of the invention is an improved end structure for such seats so as to secure a lighter and stronger con struction than heretofore, and to provide improved means for securing the aisle end of the seat to the body thereof.

Because of its toughness and durability and its comparative lightness, it is desirable to construct the aisle end of the seat of sheet metal, but, because of its relative thinness, the attachment of the end. of the seat has presented several difficult problems, inasmuch as the seat end is frequently subjected to sudden strains and is compelled to sustain a portion of the shock due to shifting of the back of the seat and to the strains caused by the pressure of a passenger against the back.

According to my invention, the aisle end of the seat is formed of sheet metal, and the end plate of the seat is formed of similar material. These two parts or elements are formed, or provided with relatively large interlocking members which accurately fit one within the other and which also stiffen and strengthen said parts or elements. Preferably the inner wall of the seat end is formed with a concavo-convex protuberant member by suitable dies, and the end plate, which is rigidly secured to the seat rails, is provided with a marginal flange so that it may he slipped over and accurately embrace such protuberant member. Fasten-- ing means are provided for securely attaching the end plate and the seat end in their interlocked relation.

Referring to the drawings,-Figure 1 represents a. perspective view of the aisle end of the seat. Fig. 2 represents a. vertical transverse section through the seat, the cushion and the rockers therefor, the back and the back-supporting arms being illustrated in dotted lines, and the seat rail being Specification of Letters Patent.

Fig. 5 represents asection on the line 55" of F 1g. 4.

It will be understood that the seat, so far as its major construction 18 concerned, may

be like those now manufactured and will be provided with the usual seat rails 10, 10, which are supported at one end by a pedestal indicated in dotted lines at 11.

- 12 indicates the end plate and 18 indicates the seat end. The seat end is, as stated, preferably constructed of drawn sheet metal and is hollow, as indicated in Figs. 3, at and 5. It is provided with the outer wall let and the inner wall 15, said walls being so stamped as to provide uprights 16, 16, to receive on their upper ends the arm which is preferably constructed with a drawn metal lower portion 18 and a wooden portion 19 suitably secured together.

The drawn metal portion 18 is attached rigidly by welding or otherwise to the upper ends of the standards 16. The inner wall .15 is formed with an integral, exteriorly projecting protuberant member 20, in the shape of a segment of a circle and having a flat face a and a marginal wall Z). The upper portion of the wall is illustrated as arcuate and the lower portion is straight, as shown in Fig. 1. The formation of the inner wall of the seat end with the protuberant member 20 has the effect of stiffening it and rendering it less liable to bend under strains. The end plate 12 is substantially segmental and approximates in outline the member 20. It consists of a flat sheet metal plate having a marginal flange 21 projecting outwardly therefrom which will accurately fit over and embrace the member 20 so that said flange 21 will engage the wall I) of the member 20. The edge of the flange 21 engages the face of the wall 15. The end plate and the seat end, after they have been interlocked, are secured together by any suitable fastening means. Preferably the end plate is formed with depressions 22, the bottom walls of which bear against the front wall a of the member 20, as shown in Fig. 4. Bolts or rivets 23 are passed through apertures in said depressions and through the Walls of the seat end, and the heads or nuts thereon as, rare.

lie in the depressions 22 so as to be countersunk below the face of the end plate. One ,;or moreadd tional screws 24 may be passed throughthe endplate into the seat end to assist in rigidly securing the seat end and the end plate firmly together. To prevent the collapsing of the hollow seat end, sleeves 25 are employed to receive the bolts or rivets .23, as shown in Figs. 3 and t. The overlappingcurved portions ofthe flange 21 and the protuberance constitute a guide for cooperating with end portions of the back or its supporting arms. In order that the end plate may be utilized to afford stops to, limit the movement of the back, it will be seen from Fig. 2 that at its ends the end plate and the marginal flange thereof project laterally away from the segmental member -20 and'are curved to provide stops 26, 27,

for the end portions of the back.

I, do not herein'claim broadly a seat end and an end plate formed with interlocking members, as that is claimed broadly in my co-pending application, which shows and describes a seat end wall fixture, the present invention relating specifically to the aisle end portion of the seat.

Having thus explained the nature of my said inventionand described a way of constructing and using the same, although withoutattempting to setforth all of the forms Copies of this patent may be obtained for in which it may be made or all of the modes of its use, what I claim is 1. A car seat comprising an aisle end plate to which the rails are secured, said plate being approximately segmental and having an outwardly projecting continuous marginal flange, the upper curved portion of which constitutes a back guide, a hollow aisle end having a complemental segmental protuber- A,

ance on 1ts inner wall extending into and embraced by the said marginal flange, said marginal flange being extended away from the protuberance at the ends thereof and forming a stop for limiting the movement of the seat back.

2. A car seat comprising rails, an end plate secured thereto, a hollow sheet metal aisle end provided with an arm, and having an inner wall and an outer wall, said end plate and said inner wall being formed one with a segmental protuberance and the other with a segmental flange to fit over and embrace the said protuberance, and fastenings for securing said wall and said end plate 5 together.

In testimony whereof I have afiixed my signature, in presence of two witnesses.
