UNITED STATES WILLIAM E. WINE, 0F TOLEDO, OHIO.

CAR-DOOR LOCK.

Application filed January 10, 1922. Serial No. 528,245.

To all whom it may concern:

Be it known that I, 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 Locks, of whichthe following is a specification.

My invention relates to new and usefu improvements in car door locking means, and more particularly to locks that are adapted to support-and retain the doors of a hopper car in their closed position.

One of the objects of the present invention is to provide. a locking device that is exceedingly simple in construction, readily assembled, cheap tomanutacture and easily and readily secured tothe car doors.

As is well known to those skilled in the art, the hoppers in a car are angularly disposed with relation to the car floor and the doors are swung'from a point at the top of the sides of the hopper.

The present invention contemplates a hook secured to the outside of the hopper while the lock comprises a body plate on which is a latch and dog, the plate to. be secured to the lower end of the door and at the side thereof. Although only one hook and one look is shown in the drawings, it will, of course, be understood that a similar hook and latch will be supplied for the other side of the hopper and door so that the door will be retained and locked from its opposite outer corners.

With these and other. objects in view, the invention consists in certain new and novel arrangements 7 and combinations of parts as will behereinafter more fully described and pointed out in the claims.

Referring now t the drawings showing a preferred form of my invention:

Fig. 1 is a fragmentary view of the side of a hopper showing the hook fastened thereon, the lock secured to the hopper door, a fragmentary portion of the door being shown andin its closed position.

Fig. 2 is a sectional view taken on line 2 2 of Fig. 1 lookinginthe direction of the arrow, and

Fig. 3 is a bottom plan View of the lock secured to the bottom of the door.

Referring now to the several figures, a;

fragmentary portion 1 of the side plate of a hopper is shown together with an outer flange 2 on a hopper door 3. The hinge point of the door 3 is not shown, butfit will be understood that it is at a point near the top of the hopper. Securely rivet- Securely riveted to the bottom of the door.

3 and directly behind the flange 2 is the triangular bracket plate 7 which is provided with the integral bosses or posts 8, 9, and

'10 which bosses all extend beyond the 0pposite sides of the plates and are each drilled as at 11 for the reception of rivets 12.

The portions otthe. bosses 8, 9 and 10 on the side of the plate form legs which rest on the bottom of the door 3 through which the, rivets 12 are passed so that the plate 7 will extend in a plane below that of the outer edge of the flange '2. Theportion of the bosses 8 and 10which extend from the opposite side of the plate 7 form bearings for the reception of a pivotal latch 13 and a dog 14-, the lower boss 9 at this side of the plate and the upper boss 8 having a strap 15 riveted to them to retain the dog 14. and hold the latch .13 from lateral movement, while the downward movement of the'latch 13 will be limited by by the boss 9 as may be clearly seen in Fig. 3. I

The location of the. casting 4L with relation to the plate 7 is such that when the door is closed and the latch" 13 is in its locked position as shown in the different figures, it will rest on the ledge 6 of the hook and cannot be lifted or removed from this position until the dog 14 is swung rearwardly, whichmay be done by striking the outwardly extending lug 16 of the door with a hammer or other instrument.

The casting 4. as well as the plate and latch 13 may be slightly cored or'ribbed as shown in the several figures to provide sufficient strength for these members, as these locking devices, as a whole, must be relatively strong as the doors and the load are comparatively heavy ones.

. h sh p o t e erouter edg o th hook 5 is such that it will raise the latch as the door is swung to its closed position so that the latch will drop into place on the ledge when the door is in its final or closed position. In other words, the latch will drop in place on the closing f the door and will there be further securely held in place by the jamming of the dog into position.

From the foregoing it will be seenthat the door may be provided with the outwardly extending flange 2 which will strengthen the door'and also shelter the bosses or posts on ithe plate 7 from injury, while at the same time, the flange does not otter any obstruction to the locking device as these bosses are of sufficient length to hold the look beyond the lower edge of the flange.

It will also be seen that l; have provided a lock which is extremely simple, that will dropinto place when the .door is .closed and on the other hand cannot become accidentally disengaged in. use.

Although I have shown the locking device in conjunction with a hopper door, it will be understood that the device might well be used with drop. bottom doors on cars of other types.

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

What I claimas new and desire to secure by Letters Patent is:

l. A car. door locking device comprising a body plate, having post-s formed thereon, said posts extending beyond the opposite Sides of said plate, and said posts being drilled, a latch pivotally secured to one of said posts, a dog pivotally secured toanother of said posts, and the lowermost post forming a lower limit of movement for said latch. r

2. A car door locking device comprising a body plate. threeposts arranged about and extending transversely on each side of said body plate, the portions of the posts on one side of the plate forming legs, adapted to be secured to a door, a dog pivotally secured to one poston the opposite side of said plate and a :latch pivotally secured beneath saiddog to another of said posts, the lowermost poston this side of the plate forming a limit for the downward movementof said latch. I

,3. In combination with a hopper and doo having an outwardly extending flange there- ,on, a hook secured to theside of the hopper, a body plate secured to the bottom of the door, integral legs formed onone side of idplate, and oppositely disposed bosses a strap connected with the lowermost boss and the boss forming a pivotal point for said dog, and said latch co-operating with said hook when the latch is in its lower position to retain the door in its locked and closed position.

4. In combination with a hopper and door, a hook secured to theside of said .hopper, a body plate, posts extending through said body plate and the portion of said posts on one side of {the plate forming legs to be secured to the door, and the portions of the posts on the opposite side of the plate rorming espectively pivotal posts and a stop, a latch secured to one pivotal post anda dog mounted on the other of said pivotal posts,.a strap connecting the pivotal post of the dog and the stop tov retain the dog and latch member on said posts, said latch member resting on said hook and held against movement when the door is in ,its closed position and said dogforming. an auxiliary locking means for said latch.

of its edges, a plate secured to the Outer face of the door near the said flanged edge thereof, a locking bar pivoted upon the plate, :the same overlying thesaid flange and extending beyond the edge of the door, a stationary hook secured to the car. side and arranged for cooperation with'the said looking bar and a dog pivotally associated with the said lockingbar and arranged to retain the same in engagement with the said hook. I
