3 Claims, 3 Drawing Figures l LOCK ARRANGEMENT FOR BOX CAR DOORS BACKGROUND OF THE INVENTION 1. Field of the Invention This invention pertains to the field of railroad cars having one or more-sliding doors, as, for instance, with railroad box cars and, in particular, deals with locking devices for holding relatively sliding doors together and releasing same as, for instance,- seen by US. Pat. No. 3,596,959 which is hereby incorporated herein by reference,
2. Description of the Prior Art The prior art teaches the use of locking devices for relatively slidable doors of railroad box cars such as US. Pat. No. 2,788,995 but does not disclose a type of lock device to apply locking forces against a door hasp-to insure positive wedging locking action of the two doors together in locked positiomThis is what the invention accomplishes.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. lis a partial view of the railroad car doors held in the locked position by the locked condition of the locking device;
FIG. 2 is sectional view taken along line 2--2 of FIG.
FIG. 3 is a partial view of the railroad car doors wherein the locking device is shown in the partially disengaged position attendant to opening of the doors.
SUMMARY OF THE INVENTION This invention relates to locking devices for relatively sliding doors of railroad box cars. The invention is for the wedge locking of the doors together by means of a diagonally double locking pin wedgingly holding the car door hasp in locked relation entailing the use of a wedge locking pin and hasp stowed .within a keeper mounted on one of the-doors. The keeper is also provided with a seat for supporting the locking pin in the unlocked position to permit removal of the hasp and its wedging cam from the keeper. The keeper and hasp are provided with further lock means and also seal means for the two locked-together doors. The invention, therefore, provides for diagonally extending double locking surfaces on the hasp and pin for securely holding of the hasp within the hasp keeper.
These and other objects will become more apparent from reference to the following description, appended claims and attached drawings.
DESCRIPTION OF THE PREFERRED EMBODIMENT construction to be utilizable for the double doors of a box car as well as for the single door of a box car. As seen from the drawings, the double doors of the box car comprise a first door 2 and a second door 4, these doors being mounted for sliding movement upon the side of the car. The door 2 is provided with a panel 6 and the door 4 is provided with a panel 8. The door 2 is also provided with a seal structure 10 which intermeshes with the seal arrangement 12 of the door 4.
The locking device 14 of the instant invention comprises a hasp or hinge member 16 which is held adjacent the seal structure 10 of the door 2 by the fixed pin 18 which is provided with a head or enlarged part 20 on a shaft part 22 and the head 20 is spaced a sufficient distance away from the mount surface 24 (see FIG. 2) to permit laterally inwardly and outwardly movement of the hasp so as to disengage the same from its keeper 26. The end 28 of the hasp 16 is provided with an elongated slot 34) which allows for longitudinal movement in a generally horizontal plane-of the hasp relative to the shaft 22 to permit disengagement of the hasp from the keeper 26 when the wedge locking pin 32 is removed from the keeper 26. The hasp member is further provided with an elongated shank portion 34 and a cam or free end portion 36 which is provided with a downwardly and diagonally extending to the right beveled edge portion 38 which in the locked position of the wedge pin and hasp cam engages complemental downwardly and diagonally extending to the right beveled edge 40 of the wedge locking pin 32 as viewed in FIGS. 1 and 3. The hasp cam bevel edge portion 38 is on the inner right back side of the hasp cam 36 adjacent the shank portion 34 and the wedge pin bevel edge portion 40 is on the upper widened part 4.2 of the locking pin 32 intermediate its upper retainer abutment or stop 44 and, its lower thinner shank portion 46 at the bottom of which is located bottom retainer abutment or stop 48.
Just inwardly of the cam portion 36 of the hasp l6 and depending therefrom is located a further locking and sealing portion 50 provided with a seal opening 52 and a lock receiving opening 54 which cooperate with the common or single seal receiving and lock receiving opening 56 on the lower lug portion 58 of the keeper 26. A sealing wire may be passed through the sealing opening 52 and the elongated hole 56 and a lock loop portion of a lock (not shown) may extend through the hasp lock opening 54 and the elongated hole 56 on the keeper for respectively sealing and locking of the hasp to the keeper in the locked position of the hasp. The keeper arrangement 26 that is mounted on the door 4 just inwardly and adjacent the seal arrangement 12 includes a backing plate or bracket member 60 and a front or-outer keeper bracket member 61 to define a wedge pin and hasp cam receiving portion or chamber 62; The front bracket 61 includes upper and lower horizontally extending bracket portions 64 and 66 defining an aperture or hasp cam entry opening 68. The top and bottom of the plates 60 and 61 define openings for extending of the wedge pin through the chamber 62 and the keeper further defines an end hasp cam receiving pocket 70 as defined by the backing plate 60 and the L-shaped or bent bracket portion 72 of the keeper 26. The lower end of the bracket 60 is provided with an L- shaped wedge pin seat member 74 to support the lower end of the shank portion 46 of the wedge pin 32 as seen in FIG. 3.
The locking pin 32 is trapped in the keeper 26 because of the upper and lower abutments 44 and 48 engaging the upper and lower edges of bracket portions 64 and 66 of keeper 26. The locking pin as positioned in FIG. 3 permits the hasp member 16 to be moved into opening 68, chamber 62 and then into the pocket 70 to permit the locking pin 32 to be driven down into a wedged locking position by a hammer as shown in FIG. 1 where the bevel edges 38 and 40 are very tightly wedged against one another to prevent accidental movement of the locking pin. The vertically extending bevel edge 76 on the shank portion 46 initially allows guiding of the locking pin into the locking position when the hasp cam 36 is in the pocket 70. The wedge pin 32 may be dislodged to an unlocked position as shown in FIG. 3 by an upward force directed by an instrument such as a hammer on one of its abutments 44 or 48 on its underside. The advantage of this novel arrangement is that it provides for easy access to the locking wedge pin for opening or closing with a hammer and, further, the locking cam of hasp 16 36 and the bevel edges 38 and 40 of both hasp l6 and pin 32 prevent accidental opening of the lock and the wedging action permits the door to be fully closed when locked. The loose fit of the hasp by its connection to the door permits easy movement of the hasp to the right and left and inwardly and outwardly as well as upward or downward movement about its pivot.
The foregoing description and drawings merely explain and illustrate the invention and the invention is not limited thereto, except insofar as the appended claims are so limited, as those skilled in the art who have the disclosure before them will be able to make modifications and variations therein without departing from the scope of the invention.
