WALL END FOR GAE-SEATS.

Specification of Letters Patent.

Patented Jan. 25, i916.

Application filed April 12, 1913. Serial No. 760,656. i

To all whom it may concern:

Be it known that I, EDWARD COPELAND LANG, a citizen of the United States, and a resident of Melrose, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Wall Ends for Car-Seats, of which the following is aspecification.

This invention has relation to seats for cars are built but is installed by the railroad company or car builder after the car has been completed. It is desirable, however, that during the construction of the car it should be provided, so far as possible, with those parts or fixtures which are to be permanently attached to the car structure,'so as to make it possible thereafter easily to equip the car with the seats. Such cars are, according to modern methods, preferably made of structural and sheet steel, although the construction of wooden cars has not entirely ceased.

The object of the present invention is to provide an end fixture which forms a part of the seat and yet which may be located and fixed to the car during the construction thereof, so as to properly locate and receive the remainder of the seat when the car is being furnished.

Another object of the invention is to provide a fixture of the character mentioned which may be constructed of sheet metal, and thus enable a tough durable fixture to be produced at relatively small cost and with greater accuracy than is possible Where castings are employed. The wall fixture sustains a portion of the weight of the seat and of the passengers, and it must be so constructed as to withstand relatively heavy strains, due to the weight mentioned, and also to the shocks resulting from shifting the back whether it be of the walk-over or turn-over type. Hence, in carrying out my invention, I employ what 1 term a wall fixture, which, as stated, is made of sheet metal stamping and which is supplied to the car builder and secured permanently to the side wall of the car during the construction of the latter. It may, however, be attached to the car wall when the seats are installed, as for instance in the case of wood sided cars. To this wall fixture is subsequently attached or secured the seat end plate which forms a part of the actual seatstructure and which fits accurately upon and is secured to the wall fixture.

On the accompanying drawings, Figure 1 represents in front elevation the wall fixture of the end seat plate, the seat'rails being shown in section and a portion of the seat being illustrated in dotted lines. Fig. 2 represents a section on the line 2-2 of Fig. 1. Fig. 3 represents the wall fixture.

Fig. 4 represents a section through the wall fixture on the line lt of Fig. 3. Fig. 5 illustrates another form of wall plate embodying the invention in which slightly different means for securing the seat end plate thereto are employed. Fig. 6 represents an end elevation of the same. Fig. 7 represents a longitudinal section therethrough on the line 7-7 of Fig. 5. It will be understood that the seat, considered as a whole,

will be provided with the usual standard or,

pedestal for supporting the aisle end thereof and with the other parts or elements with which such seats are usually provided, including the usual seat rails which are indicated at 10, 10, upon which the cushioncarrying rockers are mounted as indicated in dotted lines in Fig. 1.

The wall fixture, which constitutes the fixed end of the seat, is shown'in Fig. 3 and is indicated as a whole by the numeral 11.

It is made of sheet metal, such as sheet steel, and it has at its margina flat, laterally projecting flange 12. By means of suitable dies, the plate may be formed with a dish-like concavo-convex portion orprotuberance 13, which may be substantially oblong in frontelevation and which projects outwardly or forwardly from the base flange 12. From the face of the convex portion 13 thereis also pressed a concavow upper wall, and which protuberance forms,

as will be described, a male member for interlocking with the end plate on the seat.

"While for some reasons, due to the construction of the car, it is desirable to form the fixture with the protuberance 13, yet' it will be understood. that this feature is not necessary as the protuberance 14 may alonebeused'and its sidewalls may be connected by bendsf directly with the lateral base flange 12. The object. to be accomplished is the provision of an element on forms of railway seats and provides a conr the fixture which. may-interlock with the 1 end plate, and it isevident that the particular shape of the interlocking members may be. varied as circumstances require.

i 'The' base flange of the wall fixture is providedwith aperturesfsuch as indicated at 1.5,'through which rivets or other fastenings may be. passed to attach the fixture to the wall of the car. In Fig. 2, the wall of the .car is indicated at lG'and is represented as being made of'matched boards, in which case screws will preferably be used to secure'the' wall fixture in place,- If the wall Of' the car, however, were made of sheet steel, the end fixture would preferably be i riveted directly thereto.

Tothe wall end of the seat, there is secured as a permanent component thereof an end plate'which is indicated at 17. This plate is bolted, riveted .orotherwise secured by suitable brackets to the seat rails 10, 10.

It is provided with an'out-turned flange 18 which in end view is approximately seg- 40 mental so that it will accurately fit the protuberanceor interlocking member 14: of the wall fixture.

Then the wall fixture is in place, it presents a convex interlocking member, whereas the end plate itself provides a concave interlocking member which will slip over" and embrace, as it were, the convex member. The plate 17 and its wall or flange 18 which forms the seat back guide are preferably so formed as to afford stops or rests for the back of the seat; that is to say, it may be provided with portions 19, 19, projecting away from theends of the member 14 and suit-ably curved to afford stops as 'indicated at 20, 21, for. theback or the elements which support the back.

In order that when the seat is installed in.

the carthe end plate may be detachably secured'to the wall fixture, fastening means must be provided. Such means may take the form illustrated in Figs. 1 to4, or the form indicated in Figs. 5 to 7. That is to i say, the end plate may be'secured by screws to the wall fixture, in which event the latter i'is provided with-metallic bars or strips 22 placed' within the. member 14 and secured therein by rivets or other fastenings 23, so that screws 24 may be passed directly through the end plate and through apertures in the wall fixture into the bars or strips 22 which are tapped to receive them; or else, if desired, the fixture may be pro- .vided with key-hole slots 25, as shown in Figs. 5 and 7, through the enlarged portions of which bolts and nuts may be passed, after which the bolts may be dropped into the narrower portions of the slots and the nuts tightened. Other fastenings means than those shown could be used if desired.

. The construction which I have described, it will be seen, is applicable for a variety of venient means for accurately locating and tinuous bearing for the end plate of the seat,

interlocking therewith so as to prevent lost motion and accurately locate to the seat in its desired position. The formation of the end fixture with the concavo-convex protuberance or member stiifens the plate and greatly increases its rigidity. This rigidity is increased in the form shown in Fig. 3 by the employment of the bars or strips 22.

It is not essential that the base flange should extend entirely around the wall fix-' ture, although it may do so as shown in Fig. 5. In Fig. 4, the base flange is omitted along the upper edge of the wall fixture, since in some cars, there is in the wall a flange projecting inwardly therefrom which makes such omission necessary.

WVhile the seat end as herein shown is adapted to be rigidly and permanently affixed to the car, yet, broadly considered, the

invention includes a construction in which such end may be formed or provided with an arm and located at the aisle end of the Having thus explained the nature of my 1 said invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, what I claim is:

1. Means for attaching the end of a seat comprising a wall fixture adapted to be afiixed to the wall of a car, and consisting of a sheet metal plate formed with a base flange and with a concavo-convex protuberant member segmental in face View, a concave sheet metal end plate secured to said seat and adapted to fit over said protuberant member, fasteners for securing said base flange to the car wall, and fasteners for detachably securing said end plate to said wall fixture.

2. A car seat having rails, an end consisting of a sheet metal plate provided with a protuberance, and end plate attached to said rails and having a marginal flange to inclose and fit over said protuberance, and means for fastening said end and said end plate together, the overlapping upper portions of said flange and protuberance forming a guide for the car seat back.

3. A car seat comprising rails, a sheet metal end plate attached thereto and having a marginal flange, a wall fixture adapted to be permanently attached to the car wall and consisting of a sheet metal plate formed with a base flange and a protuberant member to extend into and interlock with said end plate, fasteners for attaching said base flange to the car Wall, and independent means for detachably fastening said end plate and said wall fixture together.

4. A car seat comprising rails, a segmental sheet metal end plate attached thereto and having a marginal flange, a wall fixture adapted to be permanently attached to the car wall and consisting of a sheet metal plate formed with a base flange and a segmental protuberant member to extend into and interlock with said end plate, and means for detachably fastening said end plate and said wall fixture together, said marginal flange of said end plate being extended laterally beyond said protuberant member and being formed to provide stops for limiting the movement of the back of the seat.

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