Patented Jan. 27, 1931 PATENT OFFICE UNITED STATES BYERS w. KAZDEL, or BALTIMORE, MARYLAND GAR-noon ARRANGEMENT Application filed January 26,1923. 'Serial No; 615,154.

This invention relates to railway cars and has among its objects to provide improvements in door securing and supporting mechanisms. Another object is to provide adoor supporting mechanism wherein the door supporting members will exert a wedging action upon thedoor. Another object is to provide a door supporting mechanism adapted to prevent shifting of the door withinthe plane thereof, when closed. Other more detailed objects will appear as the description is set forth. The invention consists of the construction, combination and arrangement of parts as will be herein described and Referringto the accompanying drawings which show embodiments of the invention, Figure l is a fragmentary side elevational view of a portion-of a car having applied 29 thereto a door mechanism constructed in ac- :cordance with the principles of the present invention. Figure 2 is a transverse vertical sectional View substantially on the line A-A of Figure 1. Figure 3 is a perspective view of one :of the door-supporting mechanisms.

Figure4is an enlarged view of the eccentric 7 having a modifiedform of door-supporting arms. Figure 7 is a fragmentary plan viewv showing a portion of a door and sling for another modified arrangement of door arm. Figure 8 is a fragmentary side elevational view of a car to which is applied a modified form of the invention. Figure 9 is .a perspective view of one of the door-supporting mechanisms used in the form of the invention shown in Figure 8.

The invention is particularly adapted for use with cars of the type having a door swinging upon hinge pintles arranged lon- 'gitudinally of the car. .When cars With such doors are subjected to a heavy end impacts there is a tendency for the doors to slip or jump lengthwise of the car. The clearance side to constitute arms 10' or supporting the .door from the side Wall of the car.

-5 for "securing the brackets 13 to the car. atathe hinges permits some slippage of this character and the free edge of the door may also have additional or magnified movement relative .to adjacent portions of the car because of the yield of parts. The same action is present, although to a lesser degree, when the doors are hinged crosswise ofthe car. The embodiments shown in the drawi-ngsare in general of cars of the type having the longitudinally arranged-hinge pintles.

Referring to the embodiment shown in Figures 1 to 5, the car is provided with-a side plate 1 having a bottom flange angle 2 secured thereto by means of rivets 3. The car floor 4 is secured to the inwardly extending I legof the angle iron 2 by means of rivets 5.

A discharge openingis provided in the floor of the car and this is normally closed by means "of a door 6 which may be hinged in .anyconveninent manner to the car structure.

The door is provided on its'under face with stifiening 'members 7 which aresecured in place by means of rivets 8. Each stiffening m'ember is of channel section having bottom re-entrant flanges 9. Preferably'two of these stiffening members are applied to each door and they are spaced somewhat from each other to better stay and support the door. The ends of the stiffening members extend outwardl beneath the car The lower outer corners of the arms 10 are inclinedo'r beveled as shown at 11 to permit of some wed'ging of the door to fully close the same.

The free edge of the door is supported from the car side by means of a pair of slings 12 which are pivotally attached to brackets 13 carried by the car. These slings are arranged to swing outwardly from the face of the ear to release the door, or inwardly to supportingly engage the underfaces of the arms 10. The brackets 13 may be attached to the car side by means of rivets 14, some of the flange angle rivets 3 also being utilized for this purpose. The brackets 13 may also have portions which underlie the inturned flange of the'angle2 so as to utilize some of the rivets Each bracket 13 is supplied-with a suitable boss 15 having a longitudinally arranged opening therein. for the accommodation of the upper end of the sling 12.

Each bracket has pivoted upon it a locking cam is adapted for rotation about a pivot axis 17 which extends transversely of the car or normal to the axis of swing of the sling 12. \Vhen the slings 12 are in supporting engagement with the arms 19 the cams 16 are rotated to hold the slings in engaged relationship with the door arms and also to wedge the slings against the arms. These cams are arranged to be rotated from opposite directions into engagement with the two slings of a door and they thereby shift the slings longitudinally of the car and wedge one side of each sling tightly against its door arm. When the parts are so wedged from opposite directions, the door and the entire mechanism will be securely locked to the side of the car, thus preventing shifting of the door or accidental release of any of the mechanism. It will be understood that any impact which tends to shift any of the parts at one end of the door to-' ward release position will at the same time more tightly wedge the engaged members at the other end of the door since the door supporting mechanisms are wedged against the door in opposite directions. The cams 16 are provided with flanges 18 which overlie portions of the slings to restrain the latter against swinging away from the car when the cams have been rotated into locked position. Each cam, therefore, performsa double function; namely, it prevents disengagement of the sling 12 from its door arm and also wedges the sling 12 endwise against the door arm to stay the door against movement within the plane of its closed position. One wall of the bracket 13 is preferably extended slightly below the bottom line of the car to form a pivot support for the cam 16 and this extended portion of the bracket may also serve as a limit stop for the door arm so that by no chane can movement of the door occur beyond the limits set by the shoulders 19 of these brackets.

In the modification shown in Figure 6 the ends of the stiffening members 7 which comprise the door arms are shown as formed with oppositely arranged bevels 20. lVhen the slings 12 are swung into engagement with the door arms 10 having the bevels 20 the latter will wedge the slings in opposite directions in a manner similar to that efiected by the use of the eccentric cams 16 employed in the embodiment. In the embodiment of the invention first described shown in Figure 7 the projecting ends 10 of the arms are shown as beveled from both sides so as more readily to permit the engagement of the slings therewith. The door plate in this construction is provided with notches 21 into which the two limbs of a sling may be forced in order to provide a positive interlock between the door and the sling.

The embodiment of the invention illustrated in Figures 8 and 9 is similar to that of Figures 1 to 5, except that instead of the cocentric cam a pivoted keeper 22 is provided for the sling 12. As shown in dotted lines in Figure 9, when these keepers are in an upright position the slings may be swung out to release the door. \Vhen the slings are swung into supporting engagement with the arms 10, the keepers 22 are rotated so as to overlie the arms of the slings. Each keeper is provided with a hooked end 23, said hook portions being respectively adapted to engage opposite edges of the door to hold the latter against slippage. The arrangement of these hooked ends is such that rotation of the keepers into locked position will effect a wedging action upon the door.

I have thus described several embodiments of my invention. Other embodiments are contemplated within the scope of the appended claims, without departing from the spirit thereof.
