CAR-DOOR MECHANISM.

Application filed April 10, 1922. Serial No. 551,131.

To all whom it may concern:

Be it known that I, BYERs W. KADEL, a citizen of the United States, residing at Baltimore in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Car-Door Mechanisms, of which the following is "a' and thereafter the supporting mechanism be forcibly moved into final supporting position. Another object is to provide, with a door, a swinging door hook having a lever aperture therein, which aperture may serve not only as a lever fulcrum for forcing the door shut, but may also serve as a reaction point for the lever in forcibly swinging the hook into or out of engagement with the door.

With these and other objects in view, the invention consists of the formation, combination and arrangement of parts as will be herein described and particularly claimed.

In the accompanying drawings, which show a preferred form of the invention, Figure 1 is a fragmentary side elevational view, showing a portion of a car body equipped with a door mechanism embodying the principles of the present invention. Fig

ure 2 is a transverse vertical section of the same, this view being'taken approximately on the line 2-2 of Figure 1.

Referring now to these drawings, the side of the car is indicated by the numeral 1, and.

a fragment of the floor of the car is shown at 2. Hinged in the floor of the car by means of co-operating body and door hinges 3 and 4- is a door 5, the hinge pintle being indicated at 6. The door in the present embodiment is shown as swinging transversely of the car. There is also shown a fragment of a similar door 6, which may be arranged with the door 5 to constitute a pair of drop doors. Extending along the free edges of these doors are angle iron stiffening members 7 and 8 respectively. The ends of these stiffening members extend beyond the edges of the doors where they are utilized, as at 22, to form a door supporting arm for cooperation with a swinging door supporting member, such as the hook 9. One of the hooks 9 is provided for each door, and these are pivoted to the car body by means of the pintles 10. A bracket 12 overlies the outer faces of the upper portions of the hooks, and the pintle 10 extends throu h this bracket and through the car side 1. gotter pins, such as 11, may be utilized to prevent the loss of the pintles 10. Additional rivets, such as .13, may also be utilized to secure the bracket 12 to the car side. Cams 14 of the customary type may also be supplied to hold the hooks in engagement with the doors.

The door supporting hooks 9 are each provided with a preliminary supporting ledge 15, and a final supporting ledge 16. It-is contemplated that the doors shall be lifted by hand to positions upon the preliminary ledge 15. The door to the left in Figure 1 is shown inthis preliminary position. Each hook is provided with an aperture 17 which is arranged substantially at right angles to the plane of swing of the hook. Each door is also provided with a lever seat 18 which may be riveted to the .door as by means of rivets 19. These lever seats may be formed of a short length of angle iron with the down-standing leg thereof notched out as at 20. The removable lever 21; may be inserted through the aperture l7 and the inner end of this lever positioned upon the lever seat. The inner end of the lever should preferably lie within the cut out opening 20 of the lever seats so as to avoid slippage of the lever.

With the door in the partly closed position shown to the left in Figure 1, the lever 21 is inserted through the apertures 17 and the end of the lever is positioned within the cut 20 as desired. By now bearing down upon the outer end of the lever 21, it will be noted that the lever will fulcrum upon the hook 9 and the inner end of the lever will react upwardly upon the lever seat 18, thus forcing the door completely shut. With the outer end of the lever held down, and the door thus held shut, the outer end of the lever may be I The same operation'may be followed when it is desired to release the door from the fully closed position to the preliminary position, which is sometimes desirable in cases where the contents of the car must be thawed out in cold climates.

It will be, seen that I have provided, in a very simple manner, a door mechanism which can be readily operated without expensive apparatus, for completely closin or partially opening the doors, and furt ermore, that all these operations can be done without danger of injury to the operator. The device is simple and is not liable to get out of order. Furthermore, the weight of the car is greatly reduced by the simplicity of the mechanism and the cost is also exceedingly low.

Having thus described an embodiment of my invention, what is claimed is:

1. In a door mechanism for railway cars, the combination with a swinging door of movable means operatively associated between the car body and the door for supporting the door in partly closed or in fully closed position, a lever seat formed upon the door, and an aperture formed in one of the door supporting members, the same being arranged to receive and form a fulcrum for a removable door-closing lever.

2. In a door mechanism for railway cars, the combination with a swinging door of a hook pivoted upon the car body and adapted to supportingly engage the door, a lever seat formed upon the door adjacent the hook, the said hook being provided with an aper ture so arranged with respect to the lever seat on the door that a door-closing lever may be inserted there-through for cooperation between the said hook and the said lever seat to force the door shut and also to forcibly swing the hook.

3. In a door mechanism for railway cars, the combination with a swinging door of a hook pivoted upon the car body and adapted to supportingly engage the door, a lever seat affixed to the door, an aperture formed in the door hook with the axis thereof at right angles to the plane of swing of the hook, said aperture being adapted to accommodate a removable lever, enterable therethrough and engageable at its inner end with the lever seat, the said lever seat being arranged to hold the inner end of the lever against movement relative to the door in a door-closing direction, and also in the directions of the vswing of the hook.

In testimony whereof I affix my signature.

BYERS WV. KADEL.
