CAB-D 0 0E AERANGEEEENT.

Application filed September To all whom it concern:

Be it known that T, WILLIAM F. CREMEAN, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Car-Door Arrangements, of which the following is a specification.

This invention relates to a door arrange ment for railway cars or the like and has among its objects to provide an improved arrangement of door-supporting mechanism. Another object is to provide a door-supporting mechanism wherein the door may be supported in partly closed or in fully closed position. Another object is to provide a doorsupporting mechanism having a plurality of door-supporting hooks, one arranged to support the door in one position and another to support the door in another position. A further object is to provide a pair of door supporting hooks arranged to swing in parallel planes and hinge upon a common pivot point, one of the hoolzs being longer than the other. A still further object is to provide a door-supporting mechanism employing a plurality of door-supporting members, one of said members being provided with a fulcrum pin adapted to accommodate a doorprying lever. A still further object is to provide a pair of correlated door-supporting hooks so arranged that one hook may be actuated independently in one direction and the other hook actuated independently in the opposite direction. Vifith these and other objects in view, the invention consists of the formation, combination and arrangement of parts, as will be herein described, and particularly pointed out in the ap pended claims.

In the accompanying drawings, which show a preferred form of the invention, Figure 1 is a fragmentary side elevational view of the side of a car, showing the lower or hopper portion thereof and in connection therewith, a door arrangement constructed in accordance with the principles of the present invention. This figure shows but half of the ordinary hopper, such as is provided for cars of the type depicted, but it will be understood th t duplicate portion of such a hopper is or aarily provided. Figure 2 is a transverse vertical sectional view through the lower portion of the hopper, taken on the line 2-2 of Figure 1. Figure 3 is a transverse horizontal section 2, 1922. Serial No. 585,845.

through the door-supporting hooks, taken on the line 33 of Figure 1. Figure 4 is an oblique sectional view taken through the pivot point of the door hooks on the line 4 l of Figure 1. Figure 5 is a fragmentary side elevational View, showing a modified form of the outermost hook, this view being similar to Figure 1.

Referring to these drawings, a fragment of the side of the car is indicated at 1, and the lowermost portion of the chute plate is indicated at 2. The lowermost edge of the side 1 may be formed along an inclined line as at 3 to define the plane of the hopper discharge opening. A reinforcing angle l may be secured to the lower edge of the side plate 1, as by means of rivets 5. This angle has an inturned leg 6 against the lower face of which the door 7 may seat when closed. Some clearance is shown in the drawings between the top or inner face of the door 7 and the lower face of the leg 6 of the angle, but such clearance is necessary in order that too great nicety is not required in the workmanship. A transverse stilfening angle 8 may extend across the car at the lowermost edge of the chute plate 2, and to this may be secured the body hinges 9. Cooperating with the body hinges 9 are door hinges 10, which are secured as by means of rivets 11 to the under face of the door. The hinge pintle is indicated at 12.

The door 7 may be of any type and is indicated in the drawings as being formed of a steel plate having marginal flanges 13 and 14 along the hinged edge and along the free edge of the door respectively.

Extending transversely of the car across and secured to the under face of the door 7 is a door stiffening member or door beam 15, this being formed in the present embodiment of a channel iron which is shown as secured to the door'plate by means of rivets 16. This channel may extend slightly beyond the outermost edge of the door and preferably has secured to its outer end a reinforcing angle iron 17. This angle iron as shown is riveted through one of its legs to the web of the door beam by means of rivets 18 while the other leg of the angle is riveted to the door plate by means of a rivet 37. The angle iron 17 is provided to locally stiffen and reinforce the door and the door beam, and also to provide a seat beneath which door-supporting members may extend and with which said members may supportingly engage. The door is arranged to be held in either partly closed or in fully closed position. a pair of door hooks 19 and 20 are provided, these being pivoted to the car body at a common pivot point 21. A bracket 22 which overlies the pivot ends of these hooks has cast thereon an integral spool 23 upon which the hooks are positioned, the eyes of the hooks being of a suitable size to operate upon the periphery of the spool 23. A rivet 24 is shown as passing through the spool 23 and the car side 1, thereby holding the bracket 22 against the car side and holding the hooks in position upon the spool 23. A cam 25 may also be pivoted between the bracket 22 and the car side to hold the hooks in engaged relationship with the door. A similar spool construction may be employed for this purpose a rivet 26 passing through this spool and through the car side. An additional rivet 27 may be employed to affix the bracket to the car side.

The hooks 19 and 20 are arranged to swing in parallel planes and it will be noted that the hook 19 is longer than the hook 20, or in other words that the supporting ledge 28 thereof is at a lower elevation than the supporting ledge 29 of the hook 20. By this means, the door may be supported in a partly closed or a fully closed position, depending upon whether the hook seat formed by the horizontal leg of the angle 17 is positioned upon the ledge of the hook 19 or upon the ledge of the hook 20.

The hook 19 is preferably located outside of the hook 20, not only in order that the bending moment in the. door beam and in the angle 17 may be reduced as a result of the shortening of the leverage, but also that the outermost hook may be accessible for the preliminary support of the door, it being the practice to lift such doors to the preliminary position by hand. This arrange ment of the hooks also permits of advantageously forming upon the outer face of the hook 19 a fulcrum such as the boss 30. Upon this fulcrum may be positioned a detachable lever 31 whose innermost end may be inserted beneath the horizontal leg of the angle 17 thereby enabling the door to be conveniently and effectively pried from a partly closed to a fully closed position. In the embodiment shown in Figure 5, the boss 30 is at a lower elevation than in the embodiment shown in Figure 1, so that the innermost end of the lever 31 may be positioned beneath the lower flange of the channel 15 in forcing the door shut.

By the provision of the two hooks with supporting ledges at different levels, the lever 31 may be fulcrumed upon one of the hooks and the door pried up, the other hook being thus left free to swing into supporting To this end,-

position beneath the door. In a previous on a hook having two ledges, one of which is adaptedto support the door in a partly closed and the other in a fully closed position. In this early arrangement, it is often diflicult to swing the hook when the lever is bearing down upon 'it. The present arrangement overcomes this difficulty.

Itis desirable in many instancesthat both hooks should be withdrawn from engagement with the door at the same time, and it is particularly desirable that when the hook 19 is swung back the hook 20 should also be swung back-with it, but it is also desirable that the hook 19 should be capable of being swung forward without hindrance from the hook 20. To this end, an interior locking arrangement is provided between the two hooks. This is formed by means of the lug 32, which is cast upon the inner face of the hook 19 and so disposed that it will engage a flange of the hook 20 when the hook 19 is driven back'as by means of blows directed against the boss 30. It will thus be seen that when the outermosthook is driven back, the innermost hook will also be driven back, but there is sufficient clearance between the lug 32 and the contactin flan e of the hook 20, as at 33, so that be ore t e lug 32 engages this flange,'the hook 19 will have been moved back some slight distance. This is desirable in order that the leg of the angle 17 forming the seat for the hooks shall not strike the ledge of the hook 19 when the loaded door is released from fully supported position upon the ledge of the hook 20. When being closed, the doors will first be swung upwardly sufiiciently to permit the hook 19 to be driven into position beneath the line of swing of the horizontal leg of the angle 17 after which they are forced to fully closed position and the hook 20 is driven into supporting position beneath this leg of the angle. The cam 25 will hold both hooks in such positions. Each hook may advantageously be formed with a web 3 1 and a marginal flange 35, and it is preferable that the web should in each 'in stance be along one side of the hook and that the flange should outstand from the web toward the outer face ofthe car. This is not only desirable, in order to provide for the interior locking features heretofore described, but it also lends itself Well to the manufacture of these hooks and provides shoulders in all directions against which operating implements may be applied.

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

What is claimed is:

1. In a car door arrangement, the combiembodiment I have shown a fulcrum formed nation with a drop door hinged to the car body, of a pair of hooks pivoted to the car body and arranged to swing in parallel planes into supporting engagement with the door, one of said hooks being of greater length than the other and being arranged to support the door in a position different from that which said door occupies when supported by the other hook.
