CORNER STRUCTURE FOR CARS.

Specication of Letters Patent.

Patented Nov. 3, 1908.

Application tiled May 1, 1908. Serial No. 430,321.

To all whom it may concern.'

Be it known that I, SAMUEL M. CUnwEN, a citizen of the United States, residing in Haverford, Pennsylvania, have invented certain Improvements in Corner Structures for Cars, of which the following is a specification.

My invention relates particularly to that class of passenger cars in which the corner posts are made so as to provide for the reception of a sliding door to extend over the platform.

In passenger cars, especially of the surburban or trolley type, the platform is a step below the loor of the interior of the car and if a sliding door is used it must either eX- tend on a level with the floor of the interior of the car or the transverse end beams of the car must be cut away for the reception of the door, so as to bring the lower portion of the door on a line with the platform. It has been impossible to construct a car according to the method last described.

The object of my invention is to provide a foot structure for the proper support of the end posts of the car, so that the channel for the reception of the sliding door can eX- tend to a point on a line with the platform of the car without weakening the car at the corner. This object I attain in the following manner, reference being had to the accompanying drawing, in Which:-

Figure 1, is an elevation of one lower corner of a car showing the platform and illustrating my invention; Fig. 2, is a sectional View on the line 2 2, Fig. 1; Fig. 3, is a perspective view of the corner' structure; and Figs. 4, 5 and 6, are detail views of the corner structure.

A is the body of the car having a floor a.

B is the platform havin a fioor b.

C is the end beam of t e car which must be securely fastened to the frame of the car and to the vertical corner posts D, D. These corner posts are spaced a sufficient distance apart to form a channel d for the reception of a sliding door which is to inclose the platform or a portion of the platform; the lower portion of the door being on a line with the platform.

In order to properly support the posts D, D and to stifen the corner so that it willl be as strong as a solid corner, I providea foot structure E made as clearly shown in the drawing, having two vertical members c and e. In the member e is a socket e for the reception of the lower end of the post D and in the member e is a socket c3 for the lower end of the post D. The members e, e are spaced apart, forming a channel d being a continuation of the channel d for the reception of the sliding door. The base E of the foot structure is on a level with the floor Z of the platform B so that a door arranged to slide in this channel can be projected to entirely close the platform. This is of particular advantage when the only door of the car is the door that incloses the platform; the door in the end partitions separating the platform from the body of the car being dispensed with.

The lower end of the socket e3 receives the end of the transverse beam C, as clearly illustrated in Fig. 1, as the corner post D extends to the base of the structure; while the post D rests upon the beam C. The structure E has reinforcing flanges i, i which act also as guides for the door and has stiifening brackets i on its under side to reinforce the base plate and has a rear stifening member i2 to give strength to the entire structure. Thus it will be seen that I can make a car 'structure in which I am enabled to provide a channel for a sliding door at the corner of the car without weakening the car structure.

While I have shown a articular form of corner structure E, it will e understood thatthis structure may be modified considerably, depending upon the ty e of car to which the improvement is ap lie In the present instance the corner osts D, D are of wood and the sockets are arge to receive the corner posts, but if corner osts of iron are used, then the sockets will e of such a size as to receive them. The reinforcing anges may be made of different shapes.

I claim 1. The combination in a car, of two corner posts, and a structure having two vertically projecting members spaced apart to form a continuation of the channel betweenn the posts and adapted to receive the ends of the osts.

2. The combination in a car in whic the floor of the body of the car is above the iloor of the platform, of a corner structure situated at the corner of the car and adapted to receive the end of the transverse bea-m and the corner post, and having a channel formed therein extending bclow the floor of the oar body.

3. The combination in a car, of a transverse beam at the end ofthe ear body, a plat form at the upper surface of the car bottom, two corner posts spaced apart to form a channel, and a structure having sockets to receive the corner posts and the beam, and hav ing a channel forming a continuation of the channel between the posts and extending below the floor of the body of the car.

4. The combination in a car, of a transverse beam at the end of the car body, two corner posts spaced apart to form a channel, a structure secured to the car body at the corner and having a channel forming a continuation of the channel between the posts and extending to the platform of the car.

5. The combination of a car in which the floor of the body of the car is above the plat form, a cross beam at the end of the car, two corner posts, a structure having two sockets, one socket receiving the outer side corner post, the other socket receiving the end of the transverse beam and the lower end of the inner corner post, said structure being channeled to a point about on a line with the floor of the platform.

6. The combination in a oar in which the floor of the body portion is above the oor of the lat'form, of a transverse beam at the end of t e car body, two corner posts, one supported a given distance from the other so as to form a channel for the reception of a door, a corner structure made in one piece and having sockets for the reception of the corner posts and. the beam, said sockets being spaced apart so as to form a channel, said channel extending to the floor of the platform.

7. As a new article of manufacture, a corner structure for the corner of a car made in a sii'lgle piece and having two vertical members, a socket in each member, said members being spaced apart to form a channel.

8. As a new article of manufacture, a corner post for cars made to form two members spaced a given distance apart, and a base plate uniting the two members, each member having a socket for the reception of a post andbraced to stiifen the structure.

9. As a new article of manufacture, a corner structure for railway cars having two vertical members spaced a given distance apart to form a channel, one member having a socket for the reception of the outside corner post, the other member having a'socket for the reception of the end beam and the inside corner post, a base plate at the lower end of the structure, and two flanges projecting from the inner side of each section so as to increase the bearing surface of the section for the guidance of a door.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
