Application filed December 27, 1913.

Q of the door sheets fit and to which said To all whom it may concern:

Be it" known that I, WALTER P. MURPHY,

;a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Doors, of which the following is a'specification.

In the drawings: Figure 1 is a front elevation of a car door embodying my invention applied to a car, the car being broken away. Fig. 2 is a vertical sectional view on the line 22, Fig. 1. Fig. 3 is an end view of the door detached. Fig. dis a top plan view of the door, partly broken away. Fig.

5 is an enlarged detail sectional view on the line 5-5, Fig. 1, looking in the direction of the arrow. Fig. 6 is an enlarged detail perspective view of one of the side marginal binding members. Fig. 7 is an enlarged detail sectional view of the joint between the corrugated sheets,

The object of my invention is to provide 4 a simple, cheap, but substantial car door of such construction that it can be easily and quickly repaired and with this and other objects in view my invention consistsv of the parts and. combination of parts as will be hereinafter pointed out.

The cardoor is made up of a plurality of corrugated sheets, 1, the adjacent marginal edges of which overlap and are interlocked as more clearly shown in Fig. 7 and.

. are secured together on eachside of a full corrugation by rugation the joints between the sheets serve to reinforce the structure. It is of course obvious that I may spot weld'the sheets instead of riveting.

3 are side marginal binders for the door which is made of angle iron, one leg of which is straight agalnst which the side marginal edges of the sheets 1 abut, whereby the ends of the corrugations are closed, the edge of this leg fitting snugly against the side of the car when in the closed position thus making a weather-proof joint therebetween. The other leg of the binder bars 3 is corrugated over which the corrugations Specification of Letters Patent.

sheets are riveted by means of the rivets- 4:- The rivets are passed through the crown of the corrugation.

5 are. gusset plates riveted to the door sheets at the top corners of the door to which suitable door hangers 6 are riveted so as to distribute theweight of the'door over a larger area of the sheet than would be possible if the hanger was fastened vto the sheet direct. The gusset plates also serve to stiffen the door. 7

At the bottom of the door I secure gusset plates 7,-the lower portion of each of which depends below the lower edge of the door proper as at 8 and engages the door guides 9 and serves to hold the door against the side of the car so asto form joint therebetween when the door is in its closed position. The rivets 10 securing the gusset plates to the door sheets pass through the crown of a corrugation. j

11 is the car sill, 12 the car floor, and 13 is a bolt securing the door guide to the car.

What I claim is 1. A metal car door comprising a plurality of corrugated sheets the adjacent marginal edges of which overlap wherebya corrugation of one sheet interlocks with a corrugation of the next adjacent sheet, means securin the adjacent sheets together through-the sides of the overlapped corrusecured to the sides of the doors, each angle bar having one leg corrugated to fit the corrugations of the sheets of the door.
