4 Claims.

My invention relates to improvements in operating and locking means for sliding car doors and. the like.

An object of my invention is to provide co- 5 operating members on a sliding door and car structure such as willpermit of the operation of a sliding door by meansoi a horizontally disposed removable bar in a manner as to permit of great leverage'being exerted for initiating the opening movement of the'door or for prying the door to fully closed position. I

Another object of myinvention is to so modify the usual securing hasp employed in connection with car doors so as to cooperate with a removable bar and fixed abutment on the car structure to move the door.

A more specificobject of my invention is to combine in one mechanism the usual door hasp with a door starter and opener in such a manner as to dispose the prying "portions in alignment with the hasp and sealing'means; In house cars and the like having a sliding door it is usual to provide a hasp on the door in combination with keeper means on the car structure for retaining the door in closed position and it is alsothe practice to provide independent of the said hasp a door starter and opener for moving the door to either open or closed position. The hasp and door starter are usually separated from each other vertically and, due to the intervening'space, it is oftentimes difiicult to bring the hasp into engagement with the keeper, and I overcome such difiiculty by making provision for prying the doors at a location in alignment with the hasp.

The combining of the sealing and operating means in one'mechanism also is conducive to a reduction in weight and makes for economy. I

For further comprehension of my invention reference is made to the accompanying drawings,

wherein: v

Fig. 1 is a side elevational View of. a part of car side and door having my improvements applied thereto; I

Fig. 2 is a sectional plan View on an enlarged scale of a portion of Fig. ltaken on a line 2-'2 of said Fig. 1; and I I Fig. 3 illustrates on an enlarged scale a vertical elevational View of the hasp and mounting therefor, as illustrated in Fig. 2. g Y

My improvements are shown as applied to a box or house car having a sliding door mounted on' anti-friction rollers adjacent the bottom of the door.

In the drawings it indicates the body of the car including side walls H, side sills l2, front door post ,l3,.said door posts being provided adjacent the front marginal edge of the door with a sealing member M. The door A is shown as including a main body plate 55 and provided at the lower part thereof with roller brackets it having 5 rollers ll. mounted upon a track IS, the latter being supported at the bottom of the door opening. The door A adjacent its front margin is provided with a front marginal reinforcing member I9 preferably formed of Z-shape having web 10 26 extending transversely of the door. The respective'fianges indicated at 2i and 22 are respectivelydisposed in'the inner, and outer plane of the door. The inner flange 25 is adapted to extend within and register with ,the sealing memher 14, and the outer flange 22 is disposed in overlying relation with and secured to the body plate I5 of/the door.

My improved construction includes a bracket B disposed onthe car structure beyond the front edge of the door, and a hasp-like member C pivotally mounted on the door on a bracket D. The hasp member extends into cooperating relation with the bracket D and is locked relatively'thereto by a sliding retainer member E. The bracket member B is provided with a base portion 23 riveted or otherwise secured to the car structure. In the case of double doors being employed it will be understood that suchmember B would be mounted on one of the doors instead of on the carstructure. Outstandingfrom the base portion 23 is a body portion 24 which is formed at its outer end with upper and lowerelongated vertical extending

portions

25 and 25 respectively.

The said portionsare spaced from each other vertically an appreciable distance to provide a recess 27 intermediate said projections, and said portions-25-and 26 have a'vertically extending T-shape slot-28 formed therein. The body portion 24 is spaced lengthwise an appreciable distance from the outer, edge of the door, and intermediate the said body portion and door there is disposed an integral bracket portion 29 which extends lengthwise of the car in alignment with the recess 21; said bracket portion 29 is provided with two pockets 30-30, said pockets being spaced from each other in the direction of movement of the door and-preferably disposed in the same horizontal plane. Rearwardly' 'of the 'pockets there is an integral bracket portion 3| adapted to brace the said portion 29 relatively of the portion 24.

The hasp-like member C is of an elongated form and is pivotally mounted at one end on a pivot 32, the latter being carried by the bracket D.

The hasp is adapted to be extended lengthwise of the door into overlying relation with respect to the pockets 3!], and the end 33 of the hasp opposite to the pivot is shaped to fit within the recess 21 of bracket B; said portion 33 is formed with a T-shaped vertical slot 34 corresponding in shape to the shape of slot 28. and 34 are adapted when the parts are in operative relation to register in order to have the retaining member E extended through the slots of both members, the said retainer being likewise formed of corresponding shape.

Intermediate its pivotal mounting and the end 33, the member C is formed with two openings 3535, said openings being located in substantially the same horizontal plane as the pockets 39. The openings 35 are flared in opposite directions as indicated at 36 and the opening through which the pivot 32 extends is likewise flared as indicated at 3?, the latter being for the purpose of providing a loose connection to allow the member C to have lateral movement and swing outwardly as well as in a plane parallel to the plane of movement of the door. The bracket member D is provided with a base portion 38 riveted or otherwise secured to the door structure, and outstanding from said base portion are walls 39 and 48 which cooperate with an outer wall 4| to form a housing in which the pivotal end of member B is extended and confined, said respective walls 39 and M providing a support for the pin 32.

That portion of the retainer E which is slidably mounted in the member B is provided with a slotted opening. 42 through which a rivet 43 extends to maintain the parts in assembled relation. The lower portion of the retainer is provided with an opening 44 adapted to register with 2. correspondingly formed opening on the member B, for the accommodation of a car seal.

The operation of the device is as follows:

Assuming the hasp to be in operative locked position as indicated in Fig. 2, to open the door the operator first efiects disengagement between the retainer E and the hasp Band the latter is then swung outwardly to the position indicated by conventional dotted lines. A removable bar F is then inserted through one of the openings 35 and into one of the pockets 30, the extreme end of the bar being confined by the pocket 30 to provide a fulcrum for the bar. Pressure is then exerted on the opposite end of the bar in a direction to open the door. During the turning movement of the bar the loose pivotal mounting of the hasp allows a certain amount of lateral movement of the hasp, and the flared openings 36 in turn compensate for relative movement between the hasp and bar brought about by the movement of the door. Should an extended movement of the door be desired, the end of the bar is moved into the next successive pocket.

The closing of the door is a'reverse operation to the above described. The operator engages one of the pockets with the end of the bar and if further movement is desired the end of the bar is transferred to the adjacent pocket and closure of the door effected. With the door in open position, the hasp swings downwardly in a plane parallel to the plane of the door and assumes the position as indicated by the dotted lines in Fig. 1, in which position it is out of the path of the discharge opening. 7

The respective slots 28' I claim:

1. In a railway car, the combination with adjacent door members, one of which is slidably mounted relatively to the other; of a keeper carried by one of said members, a hasp carried by the other of said members; said hasp when in operative relation extending beyond the edge of the door for cooperation with the keeper for retaining the door in closed position; and cooperating abutment means on the hasp and keeper adapted to receive an end of a removable bar for moving the door by a movement of the bar, said respective abutment means being disposed in alignment and in overlying relation to each other to permit of operation with the bar in a substantially horizontal plane.
