CAR-DOOR LOCK.

Application led December 19, 1924. Serial No. 756,917.

The invention relates to hopper car door securing devices and has particular reference to securing or locking` means well adapted for use in connection with the doors of a twin or other hopper car.

The object of the invention, generally stated, isrto provide means on the car body for preventing undesired rotation oi" a shaft carried by the door, the shaft forming part ot a door locking mechanism.

.Another object of the invention is the provision of a door locking mechanism including a hook carried by the car body cooper'- ating` with eccentric means carried by the door, the eccentric means being rotatable toy move the door from partly to fully closed position, the mechanism further including locking means for the eccentric n'ieans whereby unintentional or casual rotation will be positively prevented.

A further object of the invention is to provide a hopper door locking mechanism including a rockable or rotatable eccentric member or element carried by the door and cooperating with a pivoted hook carried by the car body, the eccentric member acting to retain the door in partly or fully closed osition and to move the door from partly into fully closed position and being provided with` an actuating member with which co operates retaining means on the car body whereby undesired rotation will be prevented, the actuating means for the eccentric member cooperating with the hook for lock.- ing or holding the latter likewise against movement. i

Still another object ot the invention is to provide inl combination with a pivoted. hook member and a projecting door arm or spreader, of means carried by said hook and spreader for cooperating with a pry-bar whereby the door may be forced from partially closed to 'fully closed position.

And still another object of the invention is to provide in combination with a flanged spreader bar,` of a bracket member secured thereto, said bracket member carrying lock cooperating means and being adapted to reinforce the-spreader or door arm against distortion.V i

To these and other ends the invention comprises the various elements `and combinations of elements to be hereinafter described and set Yforth in the appended claims.`

In the drawings:

Figure l is a. side elevation of a hopperl car door equipped with my locking device, the door being` in fully closed position and all of the operative parts being` in intere locked relation.

Figure 2 is a section on the line 22 of Figure l, showing a plan View oit the locking device.

igure 3 is a section on substantially the line 3-3 of Figure 2, showing the door in partly closed position with the locking` features released or in inoperative position.

Figure t is a detail view of the eccentric member.

Throughout the specification and draw ings like parts are designated by like reference characters.

Referring more particularly to the `drawings, the numeral l designates a. car hopper which is normally closed by a suitably hingedly mounted door 2 capable of swinging downwardly into open position. Se'- cured to and extendingtransversely of the door 2 is a spreader ordoor arm 3 which may conveniently be formed as a. Z-bar and which projects beyond the side of the4 door vfor cooperation with retaining means to be described. It should be stated at this point that the mechanism is intended to be applied at each side of the hopper, though .it is shown at only one side inasmuch as the other is a mere duplication.

Carried by the door arm or spreader S is a bracket designa-ted generally by the numeral` 4, which bracket includes portions 5 and 6 extending at an angle to each other and riveted or otherwise secured, as at 7 and 8, to the outstanding flange and door engaging.v flange respectively of the Z-bar spreader. The bracket 4 is shown as having a plurality of web portions 9, l0 and l1 so as to forma support or bearing for a shaft l2 formed with a crank, eccentric or cam portion 13. The shaft might be a single one, extending throughout the length of the spreader or entirely across the hoppery or a separate short shaft may be provided at` fact that in actua-l' use the strain upon ythe` shaft is such that it is maintainedalways at one end of the slots. Thisfshaft is of course intended to be restrained from longitudinal movement by any desired means whatsoever and at one end it carries a lever 15 here represented as of substantially L- shape, though naturally there is no li1nitation in this respect. The lever may be integral with the shaft or suitably secured thereto, removably or otherwise.

Suitably mounted upon the side of the car hopper l is a bracket structure indicated generally at 16, within which is pivoted, at 17, a hook 18 located in such position as to extend between the `webs l() and 11 of the bracket structure f1 and to engage the crank or eccentric port-ion 13 of the shaft. Swinging movement ot' this hook in one direction is limited owing to the provision of an extension 19 thereon engageable with a lstop 20 forming a part oit the bracket structure 16. The other end of the hook is formed with an extension 21 having an opening 22 therein Afor a purpose to be described. This hook constitutes the means cooperating with the shaft 12 for holding the door in its closed position. On one side ol" the hook 18 is a small lug or shell 18a located in such positionas to be engaged bythe lever 15 when the door is in its fully closed position, as indicated in Figure 1.`

In order that the hook 18 and lever 15, and consequently the shaft 12, may be held against undesired movement, I may provide holding means including a latch 23 pivoted at 24- within the bracket structure 16 and having ashouldered end 25 engageablewith an extension 26 on the lever 15.` It is intended that the latch 23 be held in its locked position with respect to the lever 15 bymeans of a locking cam 27 pivoted at 28 within the bracket.

In the operation, it will be seen that when the door is closed and locked, the hook 18 is in engagement with the crank or eccentric portion 13 of the shaft 12 and the lever 15 is in engagement with the latch 23 which is in turn held in its operative position by the locking cam 27. When it is desired to open the door, it is first necessary to swing back the locking cam 27 so that the latch 211 may be swung in the direction of the arrow out of obstructing relation to the extension 26 on the lever 15. The lever is then swung away from the hopper, of course out of en gagement with the shelf or lug 18a on the hook, permitting the hook to be lifted out of engagement with the shaft12, thus releasing the door.- After the door is opened', the hook 18 is retained in the same position, shown inFigures 1 and 3, owing to the engagement of the extension 19 withthe stop 20, sothat the inclined surface 29 at its free end will be in "position to be engaged by the shaft 12 upon subsequent closing of the door,

the hook being consequently lifted until the shaft passes from under the inclined surface and engages the ledge 30. It is a sim le matter to move the door, by hand, into t is partly closed position. At such a time `it will be observed that the hook 18 rests against the portion 5 of the bracket and that the heel of` the i lever rests againstthe spreader 3.

To edect full closing of the door, the lever 15 may be grasped and swung toward the hopper from the position shown in Figure 3, whereupon the crank or eccentric 13 will come into engagement with the ldge 30 of the hook and consequently :torce the door to its seat. In some instances it may be difficult, owing to the distortion of the door, to effect closure thereof by this means, and under these circumstances use may be made of a. pry-bar indicated at 31, which pry-bar may conveniently be inserted through the opening 22 and through a guide eye or the like 32 secured to the spreader. When the outer end of the prybar is thus swung downwardly the door will be 'forced to its seat. If this means be employed fory completely closing the door it is intended that the lever 15 be then swung over to bring the crank 13 in engagement with the hook ledge and to bring the lever into such position that the latch 23 may be engaged therewith and locked by means of the cam 27. Wfith the` parts in fullylocked position, thercain 2T will hold thelatch 23 m place, the latch 23 will positively prevent outward swinging movement of the lever 15, and the engagement of the lever with the locking shelf 18a willfpositively prevent movement of the hook 18 in one direction, movement in the other direction being prevented by the engagement of the extension 19 with the stop 20. As a consequence all of the parts are effectively and adequately interlocked and unintentional or accidental dislocation or derangeinent al solutely prevented.

While I have shown `and described the preferred embodiment of the invention including certainmechanical details and a speciiic` arrangement, it should be understood that this disclosure is for illustrative purposes only inasmuch asithe right is reserved to make all such changes in the form, construction and arrangement of parts as will widen the field of utility and adaptability of the invention provided such variationsl andmodifcations constitute no departure from the spirit of the invention or the scope of the claims hereunto appended. y
