' Door. Lock.

- Application filed Marclr17, 1921. Serial No. 452,929.

To all whom it may concern Be it known that I, WILLIAM E. VIINE, a citizen of the United States, residing at Toledo, inthe county of Lucas and State of Ohio, have invented certain new and useful Improvements in Door Locks, of which the.

following is a specification. i

This invention relates to door locking devices for railway cars or the like and has for its primary object to provide a simple and reliable means for holding the doors in closed position. Theinvention consists of the formation, combination and, arrangement of parts as will be herein described and claimed. 1 v i I a In the drawings which show a preferred embodiment of the invention, Figure 1 is sectional view through the securingdevice, .tlllS view being taken approximately onthe line 4-4 ofFigure 2. Figure 5 is a horizontal 86013101181 vlew taken along the irregular line 5-5 of Figure 2 and showing portions of the doorsin plan view.

Referring to these drawings, the side of the car is designated 6 with a reinforcing angle iron 29 along its lower edge. The car is shown as'equipped with a pair of doors 7 and 8, these being hinged along their remote edgesto the car floor at 9 and 10 re spectively. The doors have each a stiffen- 1ng angle iron 11 extending along their ad- 13.661113 edges in a (llI'GQtlOIl' parallel to the door l11nges, and the ends of these angle.

irons extend outside of the plane of the car side to form. seats for. the door, securing hooks 12, one of which is supplied for each side of each door. The angle irons are each other and with their. horizontal legs extending. away froin each other or toward .the door hinges. Inengaging the angle irons the hooks l2 swing toward each other beneath the horizontal legs ofthe angle irons, or toward the free edges of their respective doors;

In order to prevent the hooks from swinging laterally beyond the ends of the angle irons, each of the latter is provided with a brace casting 13 which encloses the end of the angle iron and forms a stop for the hook.

.These castings at the same time form ties or braces for the open ends of the angle irons, so as to prevent bending of the flat legs from the load. These braces aresecured to the angle irons by means of the rivets 1a. The hooks 12 are pivoted to the car side at15 and overlying them is a plate shaped bracket 16 through which the pivot rivets 17 are passed. This bracket 16 has bosses 80 on its inner face through which the rivets 17 pass and the hooks 12 swing upon these bosses. The bracket may thus be securely riveted tothe car side and the hooks be free to swing in the pocket formed by the bosses between the bracket and the car side, the bosses being of slightly greater length than the thickness of the hooks. Rivets 18 are also used to secure the bracket 16 to the car side and these pass through I "similar bosses or spacers 19. As all of these bosses are castintegral with the bracket 16 it will be evident that all of the rivets 17 and 18, as well as a later described rivet 28, serve to support the door-hook load. The bosses 19 are also so located as to form hook stops to prevent the hooks swinging inward into positions where the doors would not latch themselves when swung shut. The

.edgesof the castings 13 contact the beveled approach portions 20 of the hooks and cause the latter to retreat when the doors are lifted up.

In order to prevent the hooks from becomingaccidentally disengaged, a hook lock 21 is supplied. This lock has its upper end formedas a spacing block 22 arranged to be dropped into a position between the upper extensions 23 of the hooks. As these eX- tensions lie beyond. the pivot points of the hooks it will be evident that they approach.

each other when the hooks are swung out of engagement with the angle irons. When the lock 21 is dropped so that the block portion 22 seats between these hook extensions it will be seen that neither hook can be swung for disengagement without driving the other hook into further engagement with its angle iron. v As the limits set in the construction will not permit the total disengage ment of one hook before the other hook strikes a stop follows that'neither hook can bedisengaged without the removal of the block portion 22 from its position between the hooks.

In order to prevent the total removal and possible loss of the lock 21 a portion thereof immediately beneath the block portion 22 is made of reduced width to allow enough hook movement for disengagement and beneath this there is provided a portion with a vertically elongated slot which loosely fits upon a retaining bossQT formed upon the bracket 16. The slot of'suflicient length to allow the lock 21 to be raised the required amount to allow the withorawal of the hook from beneath the angles 11. The boss 27 "thus prevents the complete removal of the lock 21. A rivet 28 passes through the boss 27 in the same manner described for the ets 15 and 18. The hook i ck 21 may be temporarily retained in its raised position, during the operations of relea ing or closing the doors, by following a practice employed in similar operations in railroad service; namely, by inserting a wedge such as a nail or a small chip of wood between the inner face ofv the top of theblock 21 and the adjacent outer face of the car side 6.

The operation of the mechanism will be understood from the foregoing description so that those acquainted with this art may have a knowledge of'the construction and use of the device. I y

This has been described a preferred embodiment of the invention. Other embodiments are contemplated, within the scope of the appended claimspwithout leparting 'from the spirit thereof.
