UNITED STATES WILLIAM E. WINE, OF TOLEDO, OHIO.

CAB-DOOR. DEVICE.

Application filed November 16, 1923. Serial No. 675,098.

7 '0 all whom it may concem:

Be it known that I, WILLIAM E. WINE, a citizen of the United States, residin at Toledo, in the county of Lucas and gtate of Ohio, have invented certain new and useful Improvements in Car-Door Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to railway cars and more particularly to an improved hopper construction and door arrangement therefor, together with improved means for supporting the doors whereby the weight thereof will be sustained by the car sills.

An important object of my invention, generally stated, consists in providing in combination with an inclined hopper structure having a door hinged thereto, of upright load sustaining hooks adapted to maintain said door in a substantially horizontal plane, said hooks being so arranged as to be easily accessible to an operator having occasion to open or close the door.

With the above and other objects in view, the invention consists in the combination and arrangement of the several parts to be hereinafter more fully described, the novel features whereof will be pointed out in the appended claims.

In the drawings chosen to illustrate the single embodiment of the invention:

Figure 1 is a fragmentary side elevation of the hopper construction of a railway car.

Fi re 2 is a cross section on the line 22 of Figure 1.

Throughout the drawings like parts are designated by corresponding reference characters.

Referrin more particularly to the drawings, a typical hopper car is shown as provided with a side sill 1 to the inner side of which is secured a pair of metal strap membersorbails2which may preferably be held in position by transversely arranged bolts 3. These bails are inclined downwardly and inwardly with respect to the side wall of the car and constitute supports for the hop er which includes an outer inclined wall which may be formed of planking 4 overlying and secured to the bails 2 by suitable fastening means such, for instance, as bolts 5. The hopper further includes other lanking 6 which extends transversely of t car and which is so arranged as to define downwardly converging hopper end walls. The discharge opening in the hopper is defined by the edge 7 of the inclined side wall formed by the planks 4. This construction provides a hopper in which the side and end wall converge downwardly and inwardly and thus provide a discharge opening located inwardly of the side walls of the car and near the center of the track. Such hopper construction is desirable where bins are located between the rails of the track and is particularly advantageous in that the material, when discharged from the car into such bins, will not pile over the rails and interfere with the movement of the car along the track.

To close the discharge opening in the bottom of the hopper I preferably provide a pair of doors 8 extending transversely of the car and hinged at their remote edges to the lower ends of the end hopper walls defined by the planking 6. The hinge structure for each door may include a leaf 9 suitably secured, as by bolts 10 or the like, to the underside of the door and are pivoted by a pintle 11 to a leaf 12 which is also suitably secured to the adjacent bail or strap member 2 preferably by means of rivets 13. When in normal or closed position the doors are substantially horizontally arranged with their adjacent edges close together so as to form a substantial closure for the ho per discharge opening. Secured upon t e underside of each door and preferably in spaced relation to the free edge thereof, is a stiffening bar, arm or spreader 14 held by bolts 15 or the like. This arm extends outwardly to a considerable distance beyond the lower edge of the hopper side wall so as to form a door supporting member which will lie within easy reach of an operator standing alongside the car. These arms may be formed of any commercial rolled section.

The construction of ihopper, while possessing many advantages, as pointed out above, renders the application of door securing hooks of the usual type exceedingly difficult since the angularitv of the hopper side wall is so great that hooks connected thereto will be out of reach of the operator unless the operator should go between the trucks of the car and in such position the danger to him is exceedingly great. Moreover, by placing the hooks on this exceedingly sharp angle the friction generated between the hooks and the hook brackets is sufficient to prevent the free 311(1111- tended operation of the hooks by gravlty. Attention is also called to the fact that if the hooks were applied to the inclined side hopper wall the angularity of the hooks with respect to the door arm or spreader would be so great as to prevent adequate bearing between the hook face and the door arm when the hook was in locked position. To overcome these numerous difficulties I provide a metal apron plate 16, the upper portion 17 thereof being adapted to he against the outer face of the hopper end wall and the lower portion 18 being deflected at an angle to said upper portionand preferably being arranged in a substantially vertical plane. The upper portion of the apron plate is preferably secured to the adjacent planking 4; by bolts 19 and is of such length that its end portions 20 overlie and are connected to the bails 2 by rivets 21. Secured upon the outer face of the vertical portion 18 of the apron plate are brackets 22 within which are pivoted, as at 23, door supporting hooks 24 of a well known type having a plurality of ledges 25 adapted to selectively engage beneath the stiffening bars or arm 14: for holding the doors in closed or slightly open position depending upon which ledge of the hook is in engagement with the hook engaging portion of the door arm or spreader member. Pivoted locking pawls 26 of any suitable type may also be provided formaintaining the hooks in their door locking position. The project ing outer ends of the stiffening arms or spreader members 14 are preferably pro-' vided with alined holes 27v so that a pry bar or lever may be inserted in either opening to force the companion door to closed position; By providing an apron plate bridging and secured to the bails 2 it is evident that I have effected a bracing action which tends to insure rigidity of the hopper construction, and by utilizing the apron plate which is rigidly connected not only to the hopper wall but to the bails 2, the weight of the doors and the load supported thereon is in turn sustained by the hooks and the load upon the hooks is transmitted to the side sills of the car. The vertical disposition of the supporting hooks.

and their arrangement outwardly of the side edges of the discharge opening and the side edges of the doors makes them accessible to an operator without placing such person in danger.

Having now described my invention, what I claim as new and desire to secure by Letters-Patent, is:
