LATCH FOR DUMP CAR DOORS Filed Sept. 8, 1930 2 Sheets-Shoot 2 I [kl/67%; WZZZCHZ 111056612,

- opening of the door.

tion by means of nuts 18, on the outer ends of the pivots as clearly shown in Figure 2. Mounted on the pivot pin 15 is the latching dog 19, which is preferably constructed in the manner shown in the drawings. From an inspection of the drawings, it will be observed that the latching dog is provided with an L shaped slot 20, in which the pivot pin 15 is positioned for effecting the pivotal mounting of the latch. Forwardly thereof, at the outer end, the latching dog is provided with a shoulder 21 of a construction adapted to overlie and engage the angle bar 12 of the door.

The latching dog is further provided with a handle receiving socket 22, preferably of the character shown in the drawings whereby the movement thereof may be controlled by the handle 23. On the pivot pin 16, a cam shaped locking lug 23, is provided for pivotal movement and of a construction adapt-ing it'for engagement of the upper edge of the latching dog for locking the latter against accidental displacement when the door is latched in closed position. This feature is clearly shown in Figure 2. It will be observed, however, that the locking lug is free to be moved in a clockwise direction to a position of release whereby the latching dog is free to be swung upwardly as is necessary in manipulatin the latch for a partial or, complete The locking lug 23, is provided with an outwardly projecting boss 24, adapted for engagement with the strap 17, for confining the arcuate movement of the lockinglug to the effective operating movement.

\Vith the above understanding of the construction of the latch, it will be observed, as shown in Figure 2, that the latching dog may be positioned with the upwardly extending portion of the slot in engagement with the pivot pin 15, whereby the door engaging shoulder is brought to a position for engagement with the anglebar 12, for maintaining the door in completely closed position. the latching dog so positioned, the locking lug may then be moved to the full line position in Figure 2, whei-eb the door is securely held closed without lia ility of accidental dis- 1 placement or release.

Now in the event it is desired to open the door to a partial degree, this may be accomplished by first inserting the handle 23, in the socket 22, subsequently removing the locking lug to the dotted line position shown in Figure 2, so as to permit free movement of the latching dog, after which the handle is lifted in a manner to cause the latching dog to swing around the point of contact with the angle iron of the door as a pivot, and to thereby move the pivot pin 15, out of the After such movement is effected, the weight of the lading on the door is free to force the With door to the partial open position and extend sufiicient to move the latch to bring the pivot pin 15, in engagement with the extreme right hand end of the slot. When the pin reaches the end of the slot, theopening movement of the door is arrested and the door is held against further movement by the engagement of the'shoulder with the angle iron.

If it should be desired to completely open the door, after the door has already been partially opened, as shown in Figure 3, it is merely necessary to move the handle downwardly in a manner to swing the latch bodily in a clock-wise direction around the pivot pin 15, which will result in adisengagement between the shoulder and angle iron, and a full release of the door.

On the other hand, if it is desired to open the door to the full released position originally from the completely closed position, it is merely necessary, after the locking lug is removed, to thrust the handle downwardly whereupon the latch will be caused to swing in a clock-wise direction on the pivot pin 15 in the upwardly extending end of the slot whereby it will disengage the shoulder 21, from the angle iron of the door. When the disengagement isonce effected the weight of the lading will cause the door to swing to the free open position.

/ It is of course understood that the handle 23, is readily removable from the socket whereby it Wlll not be necessary to maintain the extended awkward part as a permanent attachment of the car. When the manipula 1 various objects specified therefor; It will also be. appreciated that the invention isapplicable to other forms of doors where completev closing'and opening, and a partial opening is desired, although it is recognized that the features thereof are particularly adapted to doors of hopper cars as herein illustrated.

I claim:

1. A latching device of the character described comprising a pivot, a latching dog, having a door engaging portion, and-an angular slot therethrough, said pivot being positioned through said slot for mounting said latching dog and forming a pivot therefor in either end of said angular slot, and means for manipulating said latching dog in either clockwiseor counter clockwise directions.

2. A latching device of the character de scribed comprising a pivot, a latching dog,

havin a'door en a in ortion and an an nupwardly extending portion of the slot. g g g g lar slot therethrough, said pivot being posilatching dog and forming a pivot therefor in either end of said angular slot, and a handle receiving socket on said latching dog.-

- 3. A latching device of the characters described comprising a pivot, a latching dog, having a door engaging portion and an L- shaped slot in sliding and pivotal engagement with said pivot, one end of said slot being further removed from the door than the other end thereof for operative positions of said latching dog, one arm of said slot extendingv in the direction substantially tangential to the pivotal movement of the'door at the point of engagement of the latching dog therewith.
