Application filed November 16, 1927. Serial No. 233,540.

This invention relates to devices for opening, closing and fastening sliding doors, and while capable of general use, is illustrated herein as applied to the door of a box car.

- 'One of thepurposes of this invention is to provide a device of the character indicated which will be strong and durable, economical to manufacture, easy to apply, which cannot be broken, removed or tampered with and which consequently will be burglar proof.

' Another purpose is to provide a device which will provide Considerable leverage, thereby enabling the operator to force the door into a closed position, and also to initiate its opening movement in case the door should he struck or jammed by lading piled against itsinner face.

A further object is to provide a device of this character by which the door may be 2 fastened-and sealed in a fully closed or partially open'position, as may be desirable, for purpose of ventilation or he like,

A Still further object is to provide means :for, preventing the hasp fromcoming into contact with and'breaking the seal.

Qther objects and advantages of this invention should be readily appreciated as the same becomes better understood by reference .flQ fbhB followingdescription when considered 1 insconnection with the. accompanying drawiig. 1 is a fragmentary side elevation of a carequipped with my invention;

Fig. 2 is a horizontal sectional view on the line 2+2 of Fig.1; and

Fig. 3 is a fragmentary side elevation of a car equipped with a'modified form of this invention.

Fig. 4 is asection taken at the line 4:4= of Fig. 3, v

-Fig. 5 is an enlarged section taken at the line 55 of Fig. 3.

Referring now to the drawings more in detail, reference character 4 designates a stopping post or jamb against whicha car doorfi is adapted to-close,

'erably provided onits forward edge with a rginfQrClIlg bar 6 to'prote'ct this edge against to, injury and is also provided with a horizon- The door is pref- This plate 9 is provided with an outwardly projecting hasp. receiver or keeper 13 and a vertical extension 14 as best shown in Fig. 3. 1

The hasp receiver 13 is provided on its upper face with a groove 15 adapted to receive the edge of a hasp 16 at the upper side of one of a pair of apertures 17 and 18 provided in said hasp and adapted to receive said receiverg g therethrough. The apertures 17 and 18 are spaced longitudinally in the hasp 16, the latter being pivoted as will be hereinafter explained to the door jamb whereby the door may be fastened in closed position with the-3:0 receiver 13 in the aperture 17 or in partially closed position with the receiver in the aperture 18.

The hasp 16 is provided with a handle portion 19 at one end and is pivotally attached at its other end to a bolt 21 or other fastening means securedto the door jamb. In this case the bolt 21 extends through the door jamb. In this case the bolt 21 extends through the door post 4 and is secured by a nut on the inside. A plate 22 is secured on the outer surface of the door jamb at the base of the bolt 21 and a plate-36 is secured to the first plate and provided'with a portion which is spaced outwardly therefrom the bolt 21 ex-' tending through said portion. The hasp 16 is carried on the bolt 21 between the plate 22 7 and the outwardly spaced portion of the plate 36. The inner side of the plate 36 is adapted to engage the hasp 16 whenever the same commences to swing and'thus maintains the latter in a vertical position and prevents swinging thereof in a longitudinal plane.

, By'thus preventing swinging of the hasp 16 the danger of the same being caught between 05 the edge of the door and the jamb is prevented.

When the door is in fully closed position with the receiver 13 extending through the aperture 17 in the hasp or in partially closed hasp in the groove 15 of the receiver.

position with the receiver 13 extending through the aperture 18 in the hasp, a hasp retainer and seal protector in the form of an L shaped member 24 rotatively carried by a pin 25 mounted in the upper 'end of the extension it may be rotated from the dotted line position shown in Fig. 1 to the full line position to prevent lifting of the hasp sufficiently to disengage it from the groove of the receiver and to prevent it from coming into contact with and breaking the seal as will be hereinafter explained. The member 24. is enabled to prevent lifting of the hasp when in the operative position shown in Figs. 1 and 3 by means of an outwardly projecting portion 26 which upon a selected rotative position of said member extends over the hasp 16 above the receiver 13 to'retain said When in this position a vertical aperture 27 in the vertical aperture 28in the receiver 13 exteriorly of the groove 15. The usual car seal 29 may-then be threaded through the apertures 27 and 28 so that the member 24 cannot be rotated to permit removal of the hasp to thereby open the carwithout breaking said seal. It will be noted that when the hasp is in fastened position it overlies the ends of a number of the bolts 12 so as to preclude their removal and the removal of the fastener without breaking the seal. The upper portion of the member 24' is made larger than the apertures 17 and 18 so that even i should the pin 25 be removed it would be impossible to draw said member through either i one of said apertures and gain access to the car without breaking the seal.

'The hasp 16 is designed not only to perform the function of fastening the car but to also perform the function of a door opening and door closing device thus doing away with the necessity of additional mechanism to accomplish this purpose. With this end in view the hasp 16 is shaped on its upper edge with an offset convex cam surface 31 adapted to engage an outwardly projecting stud or knob 32 carried by the plate 9 near the forward. edge of the door as shown in the construction line position 33 in Fig. 1 for forcing the door open. The lower edge of the hasp 16 opposite the surface 31 is shaped to provide a concave cam surface 34 adapted to engage the knob 32 as shown in the dotted line position 35 in Fig. 1 for closing the door. The force exerted on the handle 19 of the hasp in the construction line position 33 in Fig. 1 to open the door will, of course, be exerted in a counter-clockwise direction and vice versa, the force exerted in the dotted line position 35 to close the door will be in a clockwise direction.

The hasp affords considerable leverage which is highly desirable for opening and closing the door and this leverage is further .32. By means of this mechanism the door may be forced into an open or closed position against considerable resistance.

In the modification a U-bolt 39 is used in place of the straight bolt 21 and the plate 36 is eliminated. I

A retaining plate 38 is secured on the outer surface of. the door jamb at the base of the bolt 21 and is provided with a hole or recess into which the short leg 37 of the U-bolt fits, so as to prevent rotation of the bolt and render it impossible for a pilfer'er to unscrew the bolt and release the door. The hole or recess for the short leg is so positioned on the plate 38 with respect to the base of the U-bolt that the latter is disposed on an angle so that when the hasp is cast off from the receiver or is otherwise made without departing from the principles of this invention and I therefore do not wish to be limited to the details shown or described. V

I claim:
