1.1. DUOMLOCKIING DECF'.

Application filed January 1u, wat. Serial No. 8,e.

To all whom it may concern:

Be it known that l, WILLIAM'. E. WINE, a citizen of the 'United States of America, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Car-Door- Lookin Devices, of which the following is a speci cation. f

My invention relates to new .and useful improvements in car door'locking devices and especially to a locking device that is designed to be used on cars having drop bottom doors.

One of the objects of the present invention is to provide a locking devicewhich is eX- tremely simple in operation, readily assembled and relatively cheap to manufacture.

Another object of the invention 1s to provide a locking device comprising a pivotal hook designed to be fastened to the oar body for supporting the door, .the hook preferably engaging a ledge provided on the door. rlt`he ledge may conveniently be an angle iron secured to the bottom of the door, but any other suitable lform of means extending beyond the door may be used. To securely hold the hook in supporting engagement with the door l preferably employ a pivoted arm one end of which is capable of being swung into engagement with the hook. The arm is adapted to be held in its locking position by a dog or cam which is so mounted that it will contact with they arm adiacentJ its pivot and thereby prevent the rotation of said arm until the dog is released.

Still another object of the invention is to provide a locking device of very compact form and preferably furnished with a sheath or housing for the hook which will protect and hold the same against transverse movements.

With these and other objects in view, the invention consists in certain new and novel arrangements and combination of parts as will hereinafter be more fully described and pointed out in the claims.

Referring now to the drawings showing a referred embodiment of the invention,

diig. 1'is a sectional view taken on line 11 of Fig. 2, showing the locking device and a fragmentary portion of acar door and car body.

Fig. 2 is a side elevation showing the locking device, a fragmentary ortion of the car and door, and the dotted ines showing the arm and dog swung totheir unlocked position.

Referring now in detail to the invention, the numeral 1 designates a fragmentary poi'- tion of a car body to which is pivotally coilnected a diop door 2. An angle iron 3 is secured to the door 2 and extends be ond the free edge of the latter to adord a edge adapted to be engaged by the hook of the locking device now to be described.

This locking device may advantageousl comprise a bracket or base 4 provided wit a plate forming a housing 5 within which a hook 6 is pivotally supported by means of the bolt 7. rl[`he lower end of the housin or plate 5 is adaptedto form a stop to limit the swing of the locking device, hereinafter to be described, which holds the hook in locked position. rihe lower portion 8 of the housing is flared to allow for the swinging movement of the hook. The plate 5 is also preferably formed integral with the bracket 4 and may be strengthened by a rib 9 or by a plurality thereof if found necessaryor desrod. vLocated to the'reai of the hook 6 is an arm 10 which, at a point intermediate its ends, is pivotally connected to .said bracket 4 as at 11, so that lever arms of diderent lengths'are provided on opposite sides of said pivot. Above the arm 10 and preferably pivotally connected to said bracket in any suitable manner, is a cam or dog 12 which, when rotated in a counter-clockwise direction, willengage the shorter lever arm of the member 10 and rotate the latter in a clockwise direction until itslonger arm is brought into engagement with the lower portion or edge of the housing 5. :in this position the end of the longer arm of the member 10 will en age the rear face of the hook 6 and secure y hold the latter in Vengagement with the supporting ledge 3 of the door, as clearly shown in Fig. 2.

A strap 13 may be and preferably is provided for guiding the arm 10 and the dog 12 and to securely maintain the same against lateral movement on the bracket 4c. rlhe said bracket is preferably connected to the side of the car body by a plurality of rivets, and a plate 14 may, if desired, be placed on the inside of the car to prevent the bracket from tearing away, the said rivets being extended through said plate 14, as shown. Sonie of said rivets may be utilized as bearings for the arm 10 and the dog 12, if desired.

lll@

The hook and bracket, as well as the arm maintaining the opposite end' of said arm and dog, may be cored for lightness, if de- I have shown onl one locking device, and one side of a door, ut it is to be understood that a similar locking device will be applied to the other side of the door so that both corners will be rigidly supported and'locked in position.

From the foregoing it will be seen that I have rovided a locking device which will securely hold the door in its closed and locked position until the dog is released by hand so as to permit the longer lever arm of the member 10 to swing downwardly by gravity to released position., The locking device which is exceedingly simple in construction, easily assembled, readily and quickl operable and relatively cheap to manu acture. y

Many .slight changes might be made without in any way departing from the spirit and scope of the invention.

Havin thus described my invention, what I c aim as new and kdesire to secure by Letters Patent is:

1. A door locking device comprising a base,a hook pivotally mounted on said base, an arm pivotally mounted on said base, and positioned to the rear of the hook and ary ranged to swin-g by gravity normally away from said hook, said arm contacting and holding said hook in its foremost position when said arm is in alocking osition and means for retaining said arm 1n its locked position.

2. A locking device for doors comprisin a base, a hook pivotally mounted on sai base, a pivotally mounted arm positioned to the rear of the hook and adapted' to hold said hook in its foremost position' when said arm is swung against said hook, and means contacting with the outer end of said arm' Adisengagement of said hook and door when said arm is in locking osition. A

4. A locking device or doors comprlslng a bracket, a flared housing integral with said bracket, a hook pivotal mounted in the upper end of said housing, an arm pivotally mounted intermediate of its ends on said bracket and to the rear of said hook, said arm retaining said hook in its locked position when the end oflsa'id arm adjacent said hook is in its upper position, and means for against pivotal movement to thereby hold the arm in its locking position.

5. In combination with a freight car, a door, a ledge on said door extending beyond the side thereof, a bracket secured above said ledge, a hook in said bracket engaging with said ledge on said door when the door is in its closed position, an arm pivoted to the bracket to the rear of said hook, and contacting with said hook when said arm is swungr to a locking position, and means pivoted above said arm and adapted to engage therewith to hold said arm against rotation.

G. A locking device for doors comprising a bracket, a housing on said bracket, a hook pivotally mounted in the upper end of said housing, and an arm pivotally mounted behind said hook and contacting therewith when swung into a locked position, tho said ann being adapted also to Contact a portion of said housing, the latter forming a stop or limit for the upward movement of said arm.
