DOORS.

Application filed February 27, 19%. fierial fl l'atwfiw.

' have shown the device used in connection with a hopper type of car.

One of the objects of the present invention is to provide a locking device which may be quickly and readily attached to a hopper and door and which will be rela tively easy to operate when it is desired to both open and shut the door.

Still another object of the present invention is to provide a device consisting primarily of a hook; which ma be secured to the hopper door; a plate w ichcooperates with thehook, which plate is to be. securedto the side of the hopper, the plate having formed thereon a lug which is en aged by the hook when the door is in its 0 osed po-' sition; and a handle which is secured to the hookand passes beneath the plate secured to the side of the hopper. A handle attached to-a hook is of great advantage as it will savethe trouble of having an operator climb under the car to reach the locking device.

Still another object of the invention is to provide a locking evice for car doors where-' in a hook is used which is provided with a relatively long handle so that the hook may be easily engaged with or disengaged from a In which is formed on a plate so cured to t e side of the hopper.

Still another object of the invention is to provide a .car door locking device consisting of but few parts and wherein after the door is once looked it will be held from accidental opening, it being necessary to first release a dog by striking the same with a hammer, or bar or other instrument.

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

Referring now to the drawings showing a referred embodiment of the inventionig. l is a side elevation from beneath the car showing a fragmentary portion of a hopper, a hopper door, and the improved locking device secured'to the hopper and hopper door, the dotted lines showing the locking device disengaged and the hopper door 'swun'g to its open position.

Fig. 2 is a fragmentary end elevation.

Fig. 3 is a sectional view taken on line 3--3 of 1, and

Fig. 4; 1s a diagrammatic cross sectional view of a car, partly in elevation, showing the hoppers and the relative-location of the locking devices.

At the outset, it may be mentioned, that the device as here shown, is attached to what is known as a Barnett hopper car.

Referring now to the drawings and to Fig. 1 in particular, there is shown a portionol the outer. side sheet 1 of a hopper, the bottom chute 2 and the hopper door 3 which is hinged as at 4:, to a wall of the hopper. Secured to a side 5 of the hopper door 3 is a plate 6 having the downwardly formed extension 7 to which is pivoted a hook 8v at the point 9, the hook being in aninverted position to that of the ordinary normal position of a hook. This hook 8 has the jaw 10 which forms the ledge 11 which ledge engages a lug or rib on a plate secured to the hopper (shortly to be described) when-the door is in its locked position.

. Formed on the bottom edge of the hook is the outstanding extension 12 which has the ribbed sides 13 to partly encase one end of a handle 14L which is riveted as at 15 to the extension 12, the handle having the bent portion 16 at its outermost end.

Secured to the side of the hopper and at the lower corner is the triangular plate 17 which is provided with three integral bosses 18 through which are passed rivets 19 to secure the plate to the side of the hopper,

the bosses spacing the plate 17 away from the side sheet 1 of the hopper so that the handle 14: may pass between the plate 17 and the side of the hopper, the handle 14 being riveted to the hook 8 and bent at its outer end after the same has been passed beneath the plate 17.

Formed on the under side of this plate 17 is the elongated lug or rib 20 which is adapted to be engaged by the ledge 11 of the book 8 when the door is in its closed position. Mounted on one of the bosses 18 is the dog 21 which, when swung to its closed position, as shown in Fig. 1, engages the rear edge of the hook 8, tightly holding the same in engagement with t e ug or rib 20. This dog 21- is provided with the pro-- by the hook 8 and at the same time is always beneath the plate 17 so that it will always be held fromv'accidental loss or disengagement.

By providing a locking device of this character having the relative long handle 14, the looking or latching of the door in its closed position is much more easily accomplished than when'just a hook is used as, of course, a greater'leverage'is obtained, and the handle extends outwardly nearly to the side of the car and may be operated without crawling under the car.

In most instances of the application of this device, a similar arrangement will be used on the opposite side of the hopper door and hopper so that the door will be supported and locked at both of its free ends.

From the vforegoing it will be seen that it is a relatively easy matter to lock or unlock the hopper door and when once held in its supported position the door cannot become accidentally opened as the do firmly holds the hook in engagement with t e rib formed on the plate 17.

It Wlll be understood, also, that many slight changes might be made or relative transposition of the parts, 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 LettersPatent is 1. In combination with a hopper car having a drop door, a hook pivotally mounted on the door, a bracket mounted on the side of the car hopper and having means thereon to cooperate wlth said hook to hold the door in a closed position, a handle extending from said hook and. passing beneath -said bracket and of such length that a portion of the handle remains beneath the bracket throughout the travelling of the door.

2. In combination with a hopper car having a drop door, a hook pivotally mounted near its one end on the door, a bracket mounted on the side of the car hopper, and

spaced slightly therefrom, a. lug on said bracket to cooperate with the hook to hold the door in a closed position, a handle securedto the lower end of said hook and said handle passing between the side of the hopper and the bracket, and the said handle being bent at its outer end so as to prevent its removal from beneath said bracket.

3. In combination with a hopper car hav; ing a drop door, a hook pivotally mounted on the door, a bracket mounted on the side of the car he per and spaced from the said side, and said bracket provided with a lug to cooperate with said hook to hold the door in closed position and locking means for holding the hook in engagement with the lug on said bracket, a handle secured to the lower end of said hook and passing beneath said bracket, the handle being of such length that it remains beneath the bracket during the travel of said door and the outer end of said handle being bent to prevent any accidental disengagement of the handle from the bracket.

4. In combination with a hopper car having a drop door, a hook pivotally mounted on the said door, said hook having an extension formed on its lower end and a handle secured to said extension, a bracket secured to the sideof the car hopper and spaced slightly therefrom, said handle extending beneath said bracket and of such length that it remains beneath said bracket throughout the travel of the door, the end of said handle being bent at an angle to the remainder thereof, said bracket being provided with a rib to be engaged by said hook when the door is in its closed position and means for locking the hook in engagement with said rib.

5. In combination with a hopper car having a drop door, a hook pivotally mounted on said door, said hook havin an extension formed on its lower end and a handle secured to said extension, and said handle extending from the side of the car inwardly, a bracket secured to the side of the car hopper and spaced slightly therefrom, said handle extending-beneath said bracket and of such length that it remains beneath said bracket throughout the travel of the door, the end of said handle being bent at an angle to the remainder thereof, said bracket being provided with a rib to be engaged by said hook when the door is in its closed position and means for locking the hook in engagement with said rib.

In testimony whereof I affix my signature.

WILLIAM E. WINE.
