WILLIAM E. WINE, OF TOLEDO, OHIO.

RAILWAY CAR.

Application filed June 23, 1921. Serial No. 479,728.

To all whom it may concern:

Be it known that I, WILLIAM E. WINE, a citizen of the United States, residing at T- ledo, in the county of Lucas and State of 6 Ohio, have invented certain new and useful Improvements in Railway Cars, of which the following is a specification.

This invention relates to railway cars, and has among its objects to provide an improved arrangement of drop door mechanism for the same. Another object is to provide a simple method of supporting the doors from the car structure and of positively locking them in closed positions.

With these general objects in view, the invention consists of the formation, combination and arrangement of parts as will be herein described and particularly claimed.

In the accompanying drawings, which show a preferred embodiment of'the invention v Figure 1 isa diagrammatic view showing in side elevation a portion of a railway car having drop doors arranged for the use of the present mechanism.

Figure 2 is an enlarged fragmentary vlew of the side of a car showing one of the drop doors with the locking mechanism associated therewith.

Figure 3 is a transverse vertical section taken through a portion of the car and through one of the drop'doors.

Referring to these drawings, the side of the car which is shown as constructed of horizontally arranged side lanking, is denoted by the numeral 1. nmediately beneath the side planking is a metal side sill 2, which is formed of a structural steel channel with the back of the same substantially on line with the inside face of the side planking, the web being vertical and the horizontal flanges located beneath the bottom edge of the side planking and outstanding away from the center of the car. The car may have a center sill constructed of the customary plate and channel type, as designated by'the numeral 3, on top of which may be arranged a portion of the floor planking 4.

construction are door hinges, such as 5, and

to these are swingingly attached one or more Secured as by riveting to the center sill' side of the car and are arranged to swing about an axis parallel with the center sill of the car, or in other ,words, to swing transversely of the car, thereby providing for the discharge of the lading to a point alongside of the track.

The door in the present construction is formed of door planks 7 supported upon battens I .8. A reinforcing hinge strap 9, passes beneath the planking and extends inward to the pivoted edge of the door Where it is formed in 100 fashion as at 10 to provide the door portion of the hinge. At the outer or free edge of the door this reinforcing member extends slightly outside of the lines of the car side and is there formed in 1001p fashion, as at 11, to provide an accessib e extension or hand hold for lifting the door, and also to provide a locking face for the engagement of the door supporting hooks when the door is in closed position. 76 This location of the locking hook also makes it easy to release the doors. It will be understood that a plurality of these hinge members, preferably two, are furnished for each door, and they are arranged-in spaced rela-, so tionship with each other so as to. properly support the door and to provide a reasonable hinge spacing. One of the brackets 5 should be provided upon the center sill for each of the door hinge members 9.

a gravity actuated door hook member, such as 12, is pivoted upon the side sill 2 for each of the members 9. These are arranged to swing longitudinally of the car, or at right angles to the swing of the door, about pivot points 13 and just outside of and alon the edge of the lower flange of the channe 2. These hooks, as well as their brackets now to be described, are positioned so that the books will face in the opposite directions; that is, the hooks when forced to their supporting position will swing towards the members 9 and away from each other. The positioning of these hooks to swing in the opposite irections is important and the benefits derived will be described more in detail as the specification proceeds. A bracket, such as 14, is provided for each hook 12. The said bracket preferably includes an inner plate member having projections which extend back into the cavity of the channel so as to space the outer face of the said plate in, substantial alinement 'with the outer edge of the lower flange of the "said channel. The brackets 14: are no riveted to the web of the channel 2 in order to simplify .the problem of removal for re-,

this cam, which is eccentric in shape, is rotated about its pivot 16 in one direction it allows the hook 12 to be driven out of posi-' tion beneath the portion 11 of the hinge member 9. When the hook is in position beneath the projection 11 for supporting the door, the cam 15 may be rotated in the proper direction to engage the back of the hook and hold it in position. The looped ends 11 of the members 9 serve to limit or arrest b direct contact therewith the movement 0 each hook in one direction. Thus when each hook is locked by the rotation of the cam 15 pivotal movement in one direction is prevented by the engagement of the hook wlth the hinge extension or arm 11, and pivotal movement of the hook in the opposite direction is prevented by its lockin' cam.

retaining late 17, corresponding in outline to the p ate of the bracket 14, may be applied over the hook 12 and cam .15 of each racket, the rivets coincident with the pivot points 13 and 16, as well as an additional rivet 18, passing through this plate and through the plate of the bracket 14 and the channel 2, thereby economically tying all of these parts together and producing a compact arran ment and one especially suited to roug' service. The door is thus supported at both edges upon corresponding members, namely, the hinge members 9, so that the forces are largely restricted and concentrated in these members. The looped ends 11 ofthe members 9 are arranged to sli htly overreach the free edge of the door an there constitute, as hereinbefore stated, both handholds and hook-enga g arms for cooperation with the swingmg hooks 12. It will be noted that the free ed e of the door falls approximatel on line wit the outer edge of the flange o the channel 2, and the looped ends or extensions 11 extend out beyond the lines of the door ed es and outside of the lines of the channefs. By extending the free edge of the door to and under the side 'sill 2 I obtain the maximum door opening, and in addition it will be seen that the door is supported not upon the floor of the car but u n the longi tudinal framework thereof, at is, at o posite ends upon the center and side sil the hinged edge of the door being. supported upon the center sill and the swinging edge upon the side sill. This construction relieves the floor proper from load and all vi bration which would otherwise result from the support of the doors thereu n.

bers 12 which are applied to the car side so as to swing in o posite directions. By thus arrangi the hooks and particularly in a constructlon in which the plane of movement of the hooks is parallel with the longitudinal axis of the car the effect of end shocks to which cars are subjected in service are neutralized. Among the advantages which flow from this. construction may be -mentioned the following: first, any and shock which tends by the inertia of either the hook or the door or by the hook lock or mm to release one ofthe hooks, will automatically, by reason of the other hook facing in the opposite-direction, tend to tighten this oppositely arranged or companion hook,

thus ensuring; at all times that at least one of the'two ooks by which each door is fastened will be in engagement with the door arm 11. Second, by reasonof the hooks facing in opposite directions all parts of the door and door mechanism will be tightly looked a ainst vibration when the hooks are driven ome from opposite directions. Third, the door'wili be held in its normal position with respect tothe door opening in the car floor and the weave of the car side with respect to the center sill will be prevented. Fourth, when the hooks are forced "to locked position and maintained in this position by means of the came 15, it will be seen that each door will be held against slippage either from hinge clearance or other relative movement between the door and the car body which might occur from shocks or impacts incident to service.

The invention just described is particu-- I larly a pilicable to old cars of the wooden type, alt ough it may be simple ed to advantage in man of t e most m cm forms of cars. The oors as constructed and arranged are of a very simple character and the mechanism for supporting them is economical in first cost and positive in operation. It is not contemplated to sup ly any winding mechanism-for liftin the oors as it has been found from; experience that this can be readily done by hand, so thatmany of the disadvantages incident to door operating devices are avoided the present construction.

being disposed in opposite directions with. V respect to each other and beim arranged to cooperatebetween the door an the car body in such manner thatone of mes-1- rs will arrest the door slippage longiincome tudinally of the car, in one direction and the other against such slippage in the opposite direction.
