ALBERT STAPLEY, or BELLEVILLE, ONTARIO, CANADA.

LOOK FOR CAR DOORS.

Application filed March 20, 1924. Serial No. 700,626.

To all whom it may concern:

Be it known that I, ALBERT STAPLES, a subject of the King of Great Britain, and a resident of the city of Belleville, in the county of Hastings, in the Province of On tario, Canada, have invented certain new and useful Improvements in Looks for Car Doors, of which the following is the spoclfication.

My invention relates to improvements in looks for car doors, and the object of the invention is to devise a simple form of lock adaptable for securing the sliding door of a box car and which at the same time will serve as a support for the lading card, and it consists essentially of the arrangement and construction of parts as hereafter more particularly explained.

Fig. 1 is a perspective view of my lock applied to a portion of a car door.

Fig. 2 is a plan view of the parts shown in Fig. 1.

In the drawings like characters of reference indicate corresponding parts in each figure.

1 indicates a portion of a car, and 2 a portion of a car body.

3 is a notched plate secured to the wall of the car 1 by any suitable means, the notch 4 thereof being directed outward.

5 is an orifice also formed in the plate 3 between the notch 4 and the wall of the car, thereby forming an intervening bar portion 6 between the notch 4 and the orifice 5.

7 is a bar which is secured to the car door and provided with a tapered or pointed end 8. When the lock is in the normal locking position the bar 7 extends through the orifice 5 of the plate 8.

9 is a bar portion provided in its inner face with a recess 10 forming with the outer face of the bar 7 an orifice for a purpose which will hereinafter appear.

11 is a recess formed in the inner end of the bar portion 9.

12 is a locking member provided with a tongue 13, having an inclined inner face 14 opposing the outer face of the bar 7.

15 is a recess formed in the inner face of the locking member 12 and extending transversely thereof.

16 is an orifice extending through the locking member 12 opposite a portion of the recess 15.

17 is a tongue preferably having an inclined outer edge 18. The tongue 17 is so;

cured to the bar 7 and extends through the orifice 16 when the parts are in the locking position. The end of the locking piece 12 is inclined inwardly'in curved form as in dicated at 19.

20 is a notched recess formed in the inner face of the locking piece 12 in proximity to its free end into which the bar portion 6 of the plate 3 fits when the parts are in the locking position.

21 is an orifice formed in the tongue 18.

22 is a tapered pin adapted to wedge into the orifice 21, and provided with a perforation 23 through which a sealing wire 24 extends.

25 is the seal by which the ends of the wire are secured.

26 is a card holder provided at its-lower end with a depending tongue 27 extending into the recess 10 of the bar 9 as clearly indicated in Fig. 2.

28 is a spring clip by which the card is held against the outer face of the card holder 26.

When it is desired to open the car door, all that 1t is necessary to do is to remove the sealing wire 24, drive out the pin 22, then swing the locking member 12 so that the notch 20 thereof is carried out of engagement with the bar portion 6. The car door may then be slid to its open position.

When it is desired to lock the door, all that it is necessary to do is to slide the door to the closed position, the bar 7 passing through the orifice 5, and the curved end 19 of the locking piece. 12 engaging the bar portion 6 so as to swing the outer end of such member outward and permitting the outwardly swung portion of the locking member to pass through the recess 4 of the plate 3 so that the notch 20 is carried into an engaging position with the bar portion 6.

The tapered face 14 of the tongue 13 permits the locking piece 12 to swing outward to enable such locking piece to engage the bar portion 6, as above described.

When the locking piece 12 is brought to the engaging position, it is manually forced inward against the bar 7 and the pin 22 driven into the orifice 21 and the sealing Wire 24 inserted through the perforation 23 of such pin and secured by the seal 25.

What I claim as my invention is:

1. In a box car door lock, the combination with the wall portion adjacent to the car door opening and the sliding door, of a plate carried by, the Wall portion and extending outward therefrom and having an orifice therein, a bar secured to the door and projecting beyond the edge thereof having a tapered end adapted to enter and pass through the orifice of the plate, a locking member pivotally carried by the door to bear against the outer face of the bar and having an undercut outer end edge and a recess in proximity to its end edge adapted to engage the outer edge of the plate, and means for sealing the locking member to the bar When the parts are in the engaged position.

2. In a box car door lock, the combination With the Wall portion of the car adjacent to the door opening and the sliding door, of a plate extending outwardly from the car Wall and having an orifice therein, a stationary bar member and a movable bar member carried by the door forming at their outer ends an intervening substantially V-shaped notch into which that portion of the plate between the plate orifice and its outer edge is adapted to enter when the door is slid to its closed position, and means for sealing the movable member When in its locking pocess, a locking member provided with a tongue extending into the recess permitting the tongue to swing outward, an orifice termed in the locking member intermediately of its length, a tongue extending from the stationary bar through the orifice of the looking member, means extending through the tongue for sealing the locking member in its closed position, and means at the outer end of the locking member adapted to :uitonnuzieally 5 engage the outer edge of the plate when the door is slid to its closed position.

ALBERT STLAPLEY.
