(Cl. S-308) n 7 Claims. 1

My invention relates to door mechanisms of railway cars and more particularly to door supporting mechanisms for railway gondola cars.

The principal object of the invention is to provide means for taking up wear in the door supporting mechanism so that the door may be maintained tightly closed irrespective of the time the mechanism has been in use.

A primary feature of the invention consists in pivotally mounting a door supporting hook upon an eccentric which is secured to the car body so as to be normally stationary but which can be rotated against the frictional forces securing it to the car body to raise the ledge of the door supporting hook and thereby take up wear, either in the hook itself or in the arm of the door which it engages.

Another feature of the invention consists in pivotally mounting a door supporting hook upon an eccentric which is secured to the car so as to be normally stationary and which has portions overlapping a cover plate of the door supporting hook, the eccentric being rotatable against the frictional forces securing it to the car by the application of external force to raise the ledge of the pivoted hook and thereby take up wear which may occur in the mechanism.

A still further feature of the invention consists in pivotally mounting a door supporting hook upon an eccentric which is secured to the car body and has at its outer end a lug overlapping the outer face of the cover plate of the door supporting hook, the eccentric being normally held in an immovable position but being rotatable against frictional forces securing it to the car body by the application of external forces and the lug of the eccentric being adapted to cooperate with spaced stops on the cover plate for limiting rotation of the eccentric member.

A still further feature of the invention consists in providing the door supporting mechanism with a cover plate which overlies the door supporting hook and is bulged outwardly and extends downwardly to form a support for a door prying lever, the support being formed so as to permit maximum angling in a horizontal direction of a door prying lever.

Other and more specific features of the invention, residing in advantageous forms, combinations and relations of parts, will hereinafter appear and be pointed out in the claims.

Referring more particularly to the drawings, i indicates the side sheets of a railway gondola car which are secured at their lower ends to a side sill 2 having an upstanding flange 3 and a substantially horizontal inwardly extending flange li. The inner edge of the horizontal flange d donnes one of the edges of a lading discharge opening which is normally closed by a door 5.

The door may advantageously be formed with marginal flanges 6 beneath which a reinforcing member l extends, the inner end of the member being usually provided with means, not shown, for hingedly connecting the door to the car body adjacent the center sill of the car, also not shown, whereby the hinge axis of the door is substantially parallel with the longitudinal axis of the car. In the present embodiment of the invention, this member is shown as being of substantially z-shape having a web 8 and oppositely projecting upper and lower flanges 9 and I0, respectively. The upper flange 9 of the member may be kconveniently secured to the marginal flange at the free edge of the door by an angle shaped member having a substantially horizontal flange I l riveted to the upper flange and an upstanding flange i2 riveted to the marginal flange 6. Rigidly secured to the outer end of the reinforcing member 'l and forming an extension thereof is an arm I3 adapted to be engaged by a hook I4 pivotally mounted on the car. The arm may be conveniently of modified channel shape having an upper ilange i5 rigidly secured to the reinforcing member 'i which, as it passes beyond the end of the reinforcing member, inclines upwardly and forms a flange I6 adapted to be engaged on its under side by a ledge ll of the hook I4. The arm is also provided with a web portion i8 which is likewise riveted to the web 8 of the reinforcing member and its lower edge is formed with a relatively narrow rigidifying flange I9.

Hook lli is pivotally mounted on an eccentric portion 2li of a member 2l which is rigidly se- 3 cured to the side of the car by a rivet 22 which passes through an opening 23 in the member. Intermediate its ends, the member 2l is provided with a portion 2li concentric with the opening 23 which is disposed within an opening 25 of substantially the same diameter in the upper portion of a cover plate 26 which overlies the hook.

The cover plate, which is preferably a unitary casting, has its main body portion offset from the side of the car to receive the hook but at one end it is flanged inwardly, as indicated at 2l, to provide an ear or plate portion 28 to engage the side wall of the car and be riveted thereto. At its other end, the bracket is integrally formed with an inwardly projecting boss 29 whose inner face engages the side of the car and which is apertured to receive a suitable attaching rivet 38.

Overlapping the outer face of the cover plate bounding the opening through which the member 2| extends is a circular flange 3i which may be conveniently formed integrally with member 2 l t will thus be perceived that, when the rivet 22 is driven, the eccentric member 2i by reason of the flange 3l thereof overlapping the outer face of the cover plate serves to secure the cover plate intermediate its ends to the car body.

Although being riveted to the car body, the eccentric member may nevertheless be rotated upon the application of suiflcient force to overcome the frictional forces set up by the rivet. For this purpose, the outer end of the member may be squared, as indicated at 32, to receive a wrench which will enable the application oi a suicient force to the member to rotate it against the frictional forces.

The flange 3l on the eccentric member is provided with a lug 33 adapted to respectively cooperate with abutments or stops 3Q for limiting rotation of the member 2l and thereby prevent the eccentric portion 2B from assuming a position in which the conventional hook locking cam 35 may not cooperatively engage the hook to maintain it in closed position, it being apparent that the cam is rotatably mounted upon the boss 29.

When the door supporting assembly is first applied to the car, the member 2l is adjusted so that the eccentric portion 25 will be about in the position, as indicated in Figure 1l., with the lug 33 in engagement with the lower one of the two stops 34. Thus after the mechanism has been in use for some time and parts thereof have worn to such an extent that the door is not supported in tightly closed position, as shown in Figure 2, member 2| may be rotated in an anti-clockwise direction by a wrench or other suitable mechanical advantage producing means, not shown, engaging the squared end 32 and thus rotate it against the frictional forces incident to the rivet 22 to cause the eccentric portion to assume a position wherein the pivotal axis of the hook lll has been elevated suiiiciently to take up all wear. It is to be particularly noted that member 2l is normally held against rotation by the rivet 22 but that it can nevertheless be rotated by the application of sufficient force to shift the pivotal axis of the hook to compensate for wear of the parts.

Cover plate 23 is bulged outwardly, as indicated at 35, and, as it extends downwardly, it preferably becomes increasingly narrow in width. rThe inner face of the main body portion of the cover plate may, if desired, be rigidiiied by a plurality of flanges 3l.

At its lower end, the cover plate is formed with an outwardly extending projection 38 to afford a support for a lever 39 for prying the door to fully closed position. The upper surface of the projection 38 is convexly curved, as indicated at 40 and, as the adjacent portion of the cover plate is bulged or curved outwardly, the pry bar or lever supported on the projection may angle a su'fcient distance in a more or less horizontal plane to enable it to engage the door closely adjacent the hook of the door supporting assembly.

Eccentrically operated means have heretofore been devised for shifting the pivotal axis of the door supporting hook a suflicient amount to move the door from partially closed to fully closed position. However, it will be apparent that the eccentric in the present construction is not employed for any such purpose, the door supporting hook being of the conventional form having two ledges, one for supporting the door in partially closed position and the other for supporting it in fully closed position. It is by means of the pry bar 3d that the door is raised from partially closed position in engagement with the initial ledge on the hoo. to a position of complete closure where it may be supported by the main ledge of the hook engaging the door arm.

Various modications can, of course, be made in the specic embodiment of the invention here illustrated and described without departing from the spirit and scope of the invention as deiined in the appended claims.
