CAR-DOOR BRACKET.

7 Specification of Letters Patent. Application filed April 28, 1908. Serial N 0. 429,734.

Patented Dec. 29, 1908.

To all whom it may concern:

Be it known that I, JAMES L. MALLORY, a citizen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Door Brackets, of which the following is a specification.

My invention relates to door brackets for freight cars and has for one of its principal objects to provide a bracket which shall serve not only to guide and retain the lower edge of the door, but also as a stop or abutment for the door.

In the construction of box freight cars having sliding doors on the outside of the cars, it has been customary to provide a strip of wood against which the forward edge of the door abuts when the door is closed. It has been found that this strip is easily mutilated and loosened or knocked off by the door striking against it.

It is one of the objects of my invention to provide the retaining device, or bracket used toretain and guide the lower edge ofthe door, with a stop or abutment arranged so as to receive the shock of the door when it is closed, and so as to do away with the necessity of such strip, or prevent orminimize the shock of the door against it when it is used. Brackets of this sort may be located at the forward lower corner of the door and also in a position to engage the rear corner of the door when the same is opened, the position of the abutments being reversed in the two brackets.-

The invention has for a further object to provide a cardoor bracket with means for forcing the lower part of the door inwardly toward the car so as to make the closure more secure.

My invention has for further objects such new and improved constructions and arrangements in freight car doors and retaining brackets for the same as will be described in the following specification and set forth in the claims appended thereto. 7

The invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of a portion of a freight car and door; Fig. 2 is a sectional plan view of the same parts; Fig. 3 is a plan View of one of the brackets; Fig. 4 is a section on the line 44 of Fig. 3; Fig. 5 is a plan view of another bracket with the abutextent.

ment arranged oppositely to that of the bracket of Fig. 3 Fig. 6 is a front elevation of the bracket of Fig. 5; and Fig. 7 is a side elevation of the same.

Like characters of reference indicate like parts in the several figures of the drawings.

Referring, first, to the general views of Figs. 1 and 2, A represents a portion of the under frame-of a railroad box car, B the sidingof the car, C, C the door posts, C the strip on the post C against or into proximity to which the door closes, E a car sill, F the flooring, and G the sliding door which may be of any preferred construction and is hung on the outside of the car.

H represents a bracket attached to the sill of the car at the forward edge of the door when the latter is closed, J a bracket at the rear corner of the door, and K a third bracket arranged so as to receive the rear corner of the door when the door is opened to its widest The constructions of brackets H and K, which form the subject-matter of this application, areshown in detail in the remaining figures.

Referring tov Figs. 3 and 4, the bracket H is shown consisting of an attaching plate 8 having the unprotected bolt or screw holes 9, one of which is shown in Fig. 4, and a bolt or screw hole for an attaching bolt or lag 10 which is protected by means of the upstanding ribs 11 in the manner shown in Patent No. 894,002, July 21, 1908, to Edward A. Hill. The bracket is provided with an upstanding lip 12 which is preferably oblique to the door so as to force the door inwardly as it is being closed. At the forward side of the bracket is aflange 13 which forms a sto or abutment for the edge of the door. The 001' itself is, preferably, though, perhaps, not necessarily, provided with an angular metal shoe 14 which extends around the forward lower corner of the door. is rounded so as to have a the lip 12.

The bracket K is in all respects like the bracket H, except that its abutment or stop 13 is placed on the opposite side of the bracket and its door-retaining lip 12 is slanted in the opposite direction.

It will be seen fromFigs. 1 and 2 that when the door is opened to its widest extent, the lower rear corner of the door will be received in the bracket K and firmly held between wedge action on The corner of this shoe abutment 13 and the lip 12. This corner of the door may be provided with an angular shoe or wedge 14 The bracket J, through which the door must, of course, slide, may be any desired type of bracket. 1 have shown in the drawings a bracket at this place made in accordance with the patent of Edward A. Hill above referred to.

I wish it to be understood that I do not limit myself to the particular forms, devices and constructions herein shown and described, as obvious modifications might be devised without departure from my invention.

I have shown the improved constructions of this application as improvements upon the type of bracket commonly called safety or burglar-proof brackets, which form of retaining device is characterized by the protection of the attaching screw or lag against removal when the door is closed.

My invention might be utilized in connection with other car door brackets of different type. For example, it is not essential that the bracket K should be of the safety type, or of the particular safety type shown.

I claim:

1. The combination with a car having a door supported to slide on the outside of the car, of a door-retaining bracket for the lower edge of the door consisting of an attaching plate, a retaining and guiding lip which extends from the plate under and around the lower edge of the door, and an upstanding and outwardly projecting abutment for the vertical edge of the door.

2. [he combination with a car having a door supported to slide on the outside of the car and a strip 011 the outside of the car into proximity with which the door is closed, of a door-retaining bracket for the lower edge of the door consisting of an attaching plate, a retaining and guiding lip extending. from the plate under and around the lower edge of the door, and an upstanding and outwardly projecting abutment for the vertical edge of the door to prevent the door from striking against said strip.

3. The combination with a car and a sliding door on the outside of the car, of a retaining device for the lower edge of the door, comprising a door-retaining lip and an abutnent for a vertical edge of the door, a shoe on said door, said shoe and lip constructed so as to have wedge action one upon the other.

t. The combination with a car and a sliding door on the outside of the car, of a retaining device for the lower edge of the door, comprising a door-retaining lip oblique to the door and an abutment for a vert' ml edge of the door, and an angular shoe on the corner of said door which comes against the lip and abutment.

5. The combination with a car and a sliding door on the outside of the car, of a retaining device at the forward corner of said door when closed, comprising a door-retaining lip and an abutment for one vertical edge of the door; a retaining device through which said door slides in being opened and closed; and a retaining device to receive the rear corner of said door when opened, said device comprising a door-retaining lip and an alnitmeut for the other vertical edge of the door.
