C'AR-DOOR-LOCKINGDEVICE.

Application filed March 17, 1922. Serial-No. 544,416.

My invention relates to new anduseful improvements in supporting and locking devices for freight car doors, and has for its object to provide an advantageous construction involving the combination of a plurality of hooks pivotally mounted on the side of the car body, a shaft ext-ending longitudinally of the car body provided at predeter mined intervals. with members adapted to cooperate with the hooks, the car doors being equipped with arms or brackets adapted to be engaged by the respective hooks to thereby support the doors iii-closed position, and 'tliemcmberson the shaft which cooperate with the hooks being capable of forcing said hooks into or out of engagement with the brackets carried by the doors when the longitudinally extended shaft is shifted in the proper direction to effect the result desired.

Another object of the invention is to .provide a supporting and locking device for the drop doors of a freight car permitting the latter to drop successively andallowingany of the doors to be closed and supportedin any order desired.

Still another object of the invention 1s to provide means for readily lockingaga nst longitudinal movement and quickly releas ing a lrmgituoinally extending shaft which is slidably mounted in brackets secured to the carside sill and is furnished with means for succ vely actuating pivoted hooks employed for supporting drop doo rsof car.

A still further object of the invention 15 to provide a locking device which may be i-cv ly attached. to freight cars having drop bottom doors, which is comparatively cheap to manufacture, is easily assembled, and is ethic-lent in scrvic i-arv feature of the invention conproi'iding for thedrop doors of a freight car supper W and lockingdevices comprising a plurality of hooks pivotally mounted on t e side of adapted su'i'ig into ment with suitable brackets secured to the door and extending beyond the free edge of the latter, in combination with a longi tudinallv extending shaft provided with means for successively rotating the hooks so the car body and supporting engage as to'relea'se the doors one after another, means also being provided whereby the several hooks are locked in door supporting position through the intermediacy of means operating to lock said shaft.

A further feature of the invention consists in providing a door locking mechanism capable of supporting and locking in supported position all the drop doors on one side of a freight car, the said locking mecha nism comp ising a plurality of brackets rigidly secured to the side sill of the car and adapted to'form pivotal supports for a plurality of door supporting hooks as well as to afford bearings for the support of a horizontally extending shaft upon which are mounted a plurality of pairs of fingers corresponding in number to the door supporting hooks, the said lingers being adapted to actuate the hooks so as to cause the "latter to engage with or be disengaged from angleirons or brackets secured to the car doors and being so related that the hooks may be successively released, thereby enabling the doors to be released with a less application of force than would be necessary to release all the doors at one time. i

Other objects of the invention and other features of construction residing particular details of elements and combinations of parts will be hereinafter more fully described and pointed out in the claims.

Fig. 7.

Figures 8, 9 and 10 are detail views of one of the fingers secured to the operating shaft.

The locking device is shown as applied to the doors on one side of the car, but it 1s to be understood thata similar arrangement is to be employed on the other side.

The freight car 1 which has been chosen for the purpose-of illustrating the invention is furnished with drop bottom doors 2 which are hinged along theirrear edges (see Fig.4) to suitable brackets 3 riveted to the center sill 4. Each of these doors is provided with suitable armsflor brackets which may conveniently consist of angle irons 5 attached to thebottomofflthe door and extending outwardly beyond the freeedge of the door upon which they are mounted. The carvillustrated in the drawings is of the type having a hopper 6, the

' which are respectively provided with bosses 11 forming pivotal vsupports for door supporting hooks 12. Eachof the brackets 10 is preferably also fashioned with a downwardly extending arm 13 in the lower end of which a bearing 14; is provided. 1 Suitably supported in the bearings '14 is, a shaft 15 which preferably extends longitudinally of the car throughout the full length of the latter. and which may advantageously be tion. I V i 'lhejaw or supporting ledge of each-of either squareor rectangular incross sec- 5 the pivotedhooks 12 is adapted to extend .undenand engage the upper or horizontal leg of the corresponding angle iron 5 car ried by the adjacent'door, the doors being arms 5, and also to enable said hooks to be swung into supporting relation to the angle" irons 5 and maintained in su chp osition, the shaft 15- is provided'with a plurality of fingers 16. These fingers, which are preferably'in the ,formof clamps embracing the shaft, are arranged in pairs, each hook be:

' are fingers 16 is formed in two pieces which'are held by a bolt 17 Thefingers are formed withrectangular or square portions 18 and with arentrallv disposed round opening 19,

while the shaft 15 is notchedat predetermined intervals so as to provide round bearing portions 20 over whichthe two' halves of the fingers 16 are clamped. The square portions 18 of the fingers by receiving and conare rigidly mounted on the shaft in a simple manner. Y

- The notches 20 in the shaft 15 are so positioned that eachofthe hooks 12 intervenes between the neighboring pair of the fingers 16, one of said fingers for each hook being adapted to contact the hook with which it is associated when the latter-is in supportlng engagementwith the angle iron door arm5. By this means theseveral hooks M revented from swinging to released pos tion when the shaft 15 is locked against shift ng As is shown in the portions A and B of Fig. 2, each door is preferably sustained V in closed position by two hooks. While the several fingers 16 which are located to the rear of the hooks (considerin the right hand end as the front of the car l are all designed to simultaneouslyengag e the respective hooks when thelatter are in locked osition, the'fingers 16 which are in front 0 thehooks are progress vely spaced in pairs, so

that the fingers in front of the hooks asso-- ciated with one doorare nearer tosaid hooks than are the corresponding fingers located in front of thehooks ofthe nextdoor. The i lost mot-ion connections between the shaft 15 and the hooks 1 2 which result from, this progressive spacing "of the fingers enables the doorsto be released successively Thus, a movement of the shaft 15 to the left will cause the fingers 16in front of the hooks associated with the portion B ofthe car to contact their hooks and force them from' engagement wltlrth'e door arm angleirons 5 before the fingers 16 in frontofthe hooks of the portion A'ofthe car force their hooks from supporting engagement'with the angle,

irons 5 of the adjacent door 2. In other words,the fingers 16 located to the front of thefhooksare' progressively spaced in pairs througout the lengthof the shaft 15,'so, that a movementof the shaft in a rearward direction will successively actuate the hooks and 1 issimultaneously. This V on. car is adapted to stand in front of and enwithout the necessity of manipulating the shaft 15, is possible because of the spaced relation of "the fingers 16 between which the hooks intervene. When it is desired to lock the doors after they have been swung upwardly and supported in closed position by the hooks 12, the shaft '15 is simply pulled forwardly so that the fingers 16 to the rear of the respective hooks force and hold all of the vsaid hooks in locking engagement with the corresponding door arm angle irons carried by the doors I As well shoi'v'n in Figs. 5, 6 and 7, means are provided forshifting the shaft 15 longitudinally and for locking it in its forward position corresponding to the locked positions of thedoor supporting hooks 12. y The means for actuating theshaft and -for locking it are preferably formed by providing the shaftnear its "end with a notch 21 for receiving a two-piece handle 22 clamped thereon. in such manner as to be capable o'f rotating slightly with respect to theshaft but without capability of longitudinal movement there- A catch 23 formed on the end -oftl e gage the handle when the shaft 15 is in its outermost position corresponding to the locked position of the hooks 12, while located above the catch 23 is a pivoted dog or cam 24 adapted to be rotated into engagement with the said handle to prevent the latter from becoming accidentally I released from its retaining catch 23. VVl-ien the doors are to be unlocked the dog 24 will be swung to the position shown in Fig. 7 and the operat: ing handle 22 will be swung-upwardly a distance sufficient to clear the catch The shaft 15 may be thereafter caused to execute a rearward longitudinal movement enabling the fingers 16 which are in front of the door supporting hooks to successively disengage said hooks from the angle iron door arms 5 of the doors, thusreleasingsaid doors one after the other. lVhcn the hooks have been disengaged from their respective door arms 5, the rod 15 will be moved midway between its extremities of travel so that the handle 22- will rest on the catch lug 23, thus bringing the hook actuating fingers 16 to a posh tion permitting the hooks to be swung as desired in either direction and thereby enabling the doors to be closed in any order desired.

It will be perceived that my invention provides means for releasing one or more of the doors by operationswhich are easily performed and that the locking of the doors is likewise easily accomplished,

Many sligh'tchanges may be nade without in any way 'departing from the spirit and scipe of the invention, and I do not wish to be in an way limited to the 'form of car shown, as the invention may be equally applied to many other forms of cars having drop bottom or similar doors. 1 Having thus described my invention, what I claim as new and desire to secure by Let ters Patent is:
