DUOR MECHANISM FOR RAILWAY CARS.

To all whom it m tag concern Be it known that I, /VILLIAM Winn, a citizen of the Unite, States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Door Mechanism for Rallway Cars; and I do hereby declare the tollowing to he 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 a door mechanism for railway cars or the like, and has for its principal object to provide an improved construction whereby hinged car doors may be closed and held in such position. Another object of the invention is to provide an improved arrangement of door supporting members by which accidental disengagement or the parts is prevented. With these and other objects in view the invention consists in the construction, combination and arrangement of parts hereinafter described In the accompanying drawings which show a preferred form of the invention,

Figure 1 is a iragmentary side elevational view of a portion of a car embodying door" mechanism involving the invention.

Figure 91 is a detail end elevation of the construction shown in Fig. 1.

Figure 3 is a sectional view on the line 3-3, Fig. 1, a removable prying lever for forcing the door to closed position being indicated in dotted lines.

Figure 42 is a diagrammatic view showing the general arrangement of the doors.

Figure 5 is a view diagrammatically illustrating the relation of the door mechanism to a car of the twin hopper type.

The car chosen for illustrating the invention is of the twin'hopper type wherein, as shown for example in Wine Patent No. 1,431,506, dated Oct. 10, 1922, two doors arranged transversely of the car are .spaced apart slightly and held in such spaced relationship by means of a door spreader which forms a stiffening beam. for supporting the doors. The ear includes a hopper end sheet 1 which is disposed in an inclined plane so that the width or the car at the hopper is less as a point near the rail than at a point further up from the rail. Attached to the hopper end. sheet is a sloping floor sheet 2, the hopper discharge opening being defined in. part by the edges of the end sheet andv the floor sheet 2. Two of these hoppers are provided at each end of the car and they are arranged on opposite sides of the center sill. A door 3 is provided. for each hopper W discharge opening, said doors being hinged to the ear body-at points near the uppermost edges of the discharge openings. This construction is well known in the art.

The edge of the hopper end sheet 1 delining the discharge opening is outwardly offset at 4 to form a shoulder 5 against which the door 3 may seat when closed. The door is similarly provided with an outstanding marginal flange 6 which-borders the outer edge of the door and forms with the outermost edge 7 of the offset portion of the side sheet 1 a pair of parailel sealing flanges preventing escape of lading from the hopper. A stifi'ening angle iron 8 may he secured along the lowest edge of the sloping floor sheet 2 in the customary manner.

The door spreader 9 is shown. as formed of a steel plate having aflange 10 lying against the outer face or" the door and se cured thereto by means of rivets 11. The web 12 of the door spreader projects outwardly or is outstanding from the plane of the door and its outermost edge is defined by an upstanding marginal flange 13. The door spreader is preferably located near the free edge of the door and extends directly across the car horizontally from a point slightly outside of one hopper end sheet 1 test point slightly outside of the correspond ing hopper sheet on the opposite side of the car. The door spreader is thus of slightly greater length than the adjacent width of the car and its general line of direction is parallel to the free edges of the doors.

The door may be held in closed positioii by means ofthe door supporting hooks 14, one of which is pivotally attached to each hopper end sheet 1. These hooks are preferably provided with preliminary supporting ledges, such as 15, and with final supporting ledges 16, which by engaging the door supporting arms constituted by the projecting ends of the door spreader enable the door to he maintained either in partly closed position or in fully closed position. -Eaeh hook is is spaced away from the general plane of the adjacent hopper end sheet 1 a sufficient distance to permit it to swingfreely alohg the outer face '2 of the offset portion of the side sheet.

Pivot brackets for the hooks are mounted cent hop er end sheet.

' spreader 9 bracket tion 18 ent device may purpose of holding the hook 14 in engaged ation with the door arm when the door 18 closed. The

bracket members

17 and 18 is connected by the rivets securing them to the car. The inner portion 17 of the thereof and terminates when mounted on the car a short distance behind the offset portion 4 of the hop er end sheet. The outer plate portion 18 of the bracket is of greater size and is arranged to extend outwardly over the oifset portion 4 to a point near the outermost edge of the side of thehopper end sheet 1. A space or way is thereby formed between the inner face of the portion 18 of the bracket and the outer face of the portion 7 of the adja- The hook 14 operor way and at the alinement transversel ivot. By this arrangement the hoo near its point of engagement with the door spreader 9, the bracket serving to support the hook in one direction and the edge 7 of the hopper end sheet supporting it from the op ositc side. swings in an inclined plane preferably agreeing with the incline of the hopper end sheet. It engages beneath a locking'face or extension 20 of the door contacting flange of the door spreader to hold the door closed. A flange 21, which is formed along. the outermost edge of the spreader, lies subltes free y in this space some time is held in of its is gui stantially normal to theplane of the lock-- mg face so that should any weaving of the car occur tending to slip the end of the spreader ofi the hook such slippage will be arrested by contact of this end flange 21 against the side of the hook.

At 22 is indicated a clearance line such as defines the equipment limits of many railroads. In order that no part of the pres extend beyond this line when the car settles and the springs go solid or when the car is operated on a curved, track, the outer ends of the door referably terminate on lines approximate y parallel with the respective lanes of the adjacent door hooks 14. The owermost corner of this spreader may go back still f rther along theincliued line to keep it we 1 within the clearance limits. 7

An aperture 23 is provided in the outer end of the hook so t at a removable door is of less extent than the outer por- The hook 14=- d prying lever 24 may be entered therethrough and brought into engagemei with the door for forcing the latter from a. partly closed to a fully closed position.
