CAR-DOOR LOCKING AND SUPPORTING DEVICE Application filed April 18, 1922. Serial No. 554,948.

To all whom it may concern:

Be it known that WILLIAM E. WINE, a citizen of the United States of America, residing at Toledo, in the county of Lucas and State of Ohio, has invented certain new and useful Improvements in Car-Door Locking and Supporting Devicesnof which the following is a specification.

My invention relates to new and useful improvements in car door locking devices and especially to a locking device, and particularly adaptable for use on Burnett hoppers for box and stock cars. 7

As is well known to those skilled in the art, this type of car has hoppers, the doors of which are hinged at their bottom and open by swinging outwardly and downwardly.

One of the objects of the present inven tion is to provide a locking device wherein the doors may be lifted to a partly and nearly closed position where they will be temporarily supported, and from which point they will then be forced to a tightly closed position; after which the mechanisms will be locked so that the doors will be finally held in a tightly closed and locked position.

Still another object of the present invention is to provide a car door supporting and locking device comprising brackets in each of which there is pivotally mounted a hook, one bracket to be secured to one side of the hopper while a second bracket is secured to the other side of the hopper, also secured to the bottom of the door is a rod having eccentrically mounted or offset pins, which are designed to be engaged by the hooks pivoted to the. sides of the hopper to thus support the door first in a temporary and then in a final position.

Still another object of the invention is to provide each of the pins atthe ends of the rods with a slight detent and to also provide the jaw of each hook with a slight projection to fit within the detents when the rod is swung to its final or locked position.

iVith 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 preferred embodiment of the invention,

Fig. 1 is a detailed side elevation of the device in relation to the hopper showing the door fully closed, the hook in locked position, and parts of the car frame in section.

Fig. 2 is a similar View but with the door in a partly or nearly closed position, the

hook in its unlocked position ready to have the eccentric tion.

Fig. 3 is a bottom plan View of a hopper and door showing the device and the rod in locked position in full lines, the rod and other parts in their released position being shown in dotted lines.'

Fig. 4 is a diagrammatic transverse sectional view through a car showing the locking device as applied thereto.

Fig. 5 is a detail of an eccentric pin and its bearing, a fragmentary portion of the rod, some of the parts being in section, and

Fig. 6 is a detailed view of an eccentric pin in transverse section showing the end portion of the hook in dotted lines.

Referring now to the drawings more in detail, there is shown diagrammatically, in Fig. 4, a section of a Burnett hopper car having the side frames 1, the side sills 2, the bottom. 3, the center sill 4, the hoppers 5 and the hopper doors 6; these doors being pivotally mounted as at 7 the bottom flange of the door fitting around the flange of the hopper sheet as is customaryin this design of car.

As the arrangement of the locking devices on each hopper is identical, a description of the one will sufiice.

Referring now more particularly to Figs. 3 and 4, there will be seen located on each side of the hopper a bracket 8 which is seecurely riveted or otherwise fastened thereto, and 1n which there is pivotally mounted a hook 9 having the projection 10 at the outer end of its jaw.

Securely fastened to the bottom of the door and at the opposite sides thereof are the bearings 11 in each of which is mounted a hub or spool 12 which in turn is provided on its outer face with an eccentrically located pin 13 having the enlarged head 14 on the end thereof. which pin is further provided with a slight cut out portion or detent 15 which is to be engaged by the projection 10 on the jaw of its co-operating hook when the door is in its closed and locked position, as will be shortly more fully described.

The purpose of this projection on the hook and the detent in the eccentrically pins turned into locking posimounted pin is that there will be an interlocking or a more tightly locking relation than would otherwise be the case as may be readily seen and understood from the drawings.

Extending completely across the bottom of the door 6 is the rod 16 having the offset portion 17 and the outwardly disposed ends 18 which are squared to fit within the opening 19 formed in each of the spools 12.

Also secured to the bottom of the door 6 are the two plates 20 which are provided with the bolts 21 which have the headed ends 22 to pass over the rod 16 when they are in their locked position, while also mounted on each of the plates 20 is the dog 23 which will engage the headed end 22 of bolt 21 after the same is shot to thereby prevent any movement of the rod 16 when in its operated position.

The operation of the device is exceedingly simple. Supposing the doors were in their open position they would be just raised by hand to a partly closed and supported position, the rod 16 being in theposition as shown in the dotted lines in Fig. 3, the hooks engaging the pins 13 as also clearly shown in Fig. 2. The rod 16 will be firmly grasped by the operator and swung downwardly to the position shown in full lines in Fig. 3 or Fig. l, and, due to the eccentric mounting of the pins l3 which will be engaged by the hook 9, the door will be forced to a tightly closed position, the projection 10 then resting within the detents 15 as illustrated in Figs. 1 and (5. After the door has been tightly closed the bolts 21 will be shot and the dogs will swing to their final position.

To open the doors, the operation just mentioned is simply reversed.

From this it will be seen that I have provlded amechanism wherein the doors may be first easily lifted and then supported in av temporary position, from which point where relative greater strength is necessary due to the fact that the doors often become warped in service, the doors by the leverage obtained may be easily forced to their closed position where they may be then locked against any accidental opening.

It will also be seen that I have provided a locking device which may be easily operated and at the same time there is an interlocking feature which will also tend to prevent any accidental disengagement. slippage. etc.

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

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
