'To all whom itniay co'ncemi Be it known that LWILLIAM E.-Wi1 m, a

citizen of'the United States of America, re-

siding at Toledo in the county of Lucas and have invented certain new and. useful Improvements in Car-Door the following is a speci-,.

State ;of Ohio,

Locks, of which fieation.

My invention relates to new and useful im rovements in car door locking means, an .more paiticularly 'to looks that are adapted to support and retain the doors of a hoppercar in their closed position.

One of the ob'ects of the present invention-is to provi e'a locking devioethat is 1y simple in'constr'uction, readily assembl and readiiy secured to the car doors.

As is well known to those skilled in the art, the hoppers in a car are angularly disosed with relation to the car floor and the oors are swung from a point at the top of v 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 are a latch and dog, the late being secured to the lower end of the oor and at the side thereof. Although onl one hook and one'lock are shown in the rawings, it will of course, be understoodthat a similar hook and the cooperating latch will be supplied for the other side of the hopper and door so that the door will be sustained and locked from its opposite outer corners. With these and otherobjects in view, the

- invention consists in certain new and novel arrangements and'combinations of the ock secured to thea-bottom of'the "door. x

will be hereinafter morefully descri d and Fig. 3 isan elevational looking at right les to the .plane. of 'the .door, showcheap to manufacture and easilyouter side of the plane below that of the outer edge of the Inge arts as now to the drawings showing a' cor 'tion until the dog 14 is swung rearwardl Referring now to the several figures, a

a hopper is own together with an outer flange 2 on a hopper door 3.

The hi pgint of the door 3 is not shown, but it understood that it is at a point near the tap of'the hopper. Securely riveted to'the 51 e of the hopper is'a casting 4 having its lower end formed in the shape of the hook 5 which extends beyond the outer edge of the hopper plate and beyond the flange 2 of the door 3. This hook 5 has the. supporting 6 formed thereon in parallel relation l die wit the outer free edge of the hopper side plate 1 and theplane of the door 3.

'Securely riveted to the bottom" of the the triangular bracket plate "7 provided with the inte a1 bosses or posts 8, 9 and 10 fragmentary portion 1 of the side plate of which exten beyond the o posite sides of i rest on the bottomof t e door 3 and throu h which the rivets 12 are passedso that t e plate 7 will extend in a 2. The ortions ofthe bosses 8 and 10 which exten from the opposite side of the plate 7 form pivotal bearings extending normal to the lane ofthedoor for the rece tion of a pivotal latch 13 and a dog 14 a apted toswrn parallel tosaid door. The lower boss 9 it t 19 side of the plate and the upper boss 8 have a strap riveted-to them' to retainthe dog. 14 and hold the latch 13 ed as at 11 for from lateral movement, while the downward movement of the latch 13 will be limited by the boss 9 as may be clearly seen in Fig. 3. The location 0 the casting 4 with relation to the plate 7 is such that when the door is clcped and the latch 13 is in its locked position, asshown =in the j'difl'erent figures, said latch will rest on the ledge cannot be lifted or removed from this posiwhich may be done by striking the outwar ly extending lug- 16 of the dog with-a hammer or other instrument. g V The casting 4'as well as the plate 7 and latch 13 may be sli htly cored or ribbed as 60f the hook and I ios shownin the severe figures to provide 813- flcient strength' for these members, ae'these 1o door 3 and directly behind the flange 2--is locking devices,as a whole, must be relatively I strong, since the doors and the load are comparat vely heavy. g

The shape of the lower outeredge of the hook 5 is such that it will raise the latch asthe door is swun to its closed position so that the latch wil drop into place on the ledge when the door is in its final or closed SOSltiOIl. In other words, the latch will re in place on the closing of'the door and wil there be further securely held in place by the jamming of the dog into position.

When the do or cam 14 is forced to locked position t e resulting wedging action ofthis arti'between the latch 13 and the bracket upon which the dog is pivotally mounted communicates, an upward thrust to said bracket and to the door upon which the latter is secured, thereby causing the door 3 to be supported and maintained against 'saging and shifting on its hinges endwise of t e door. The fixed hooks 5 which are se- I p door may be provided with the outwardly cured .to the opposite sides of theho per overlap the side edges of the door an co- 0 erate therewith to'prevent any substantial sidewise movement of the door when the latter is in closed position. .It will heappreciated that the disadvantages incident to shifting movements of the doors when the car is in service are substantiallyeliminated in a structure embodying my invention.

' From theforegoing it will be seen that the extending flange 2 which will strengthen the door and also shelter the bosses or posts on the plate 7 from injury, while at the same time the flange does not ofier any obstruc tion to the locking device as these bosses are of suflicient length tohold the lock be yond the lower edge of the flange.

It will also'beseen that I have provided alock which is extremely simple, that will dro into-place when the door is closed and "understood that the device -might well be on t e other hand cannot become accidental-. 1y disenga ed inuse.

Althoug I have shownthe locking device in conjunction with ahopper door, it willbe used with drop bottomdoors on cars of other" so ty es ila ny slight changes may be made with- I out inanyway departing froin'the spirit and scope ofthe invention.
