Original application filed January 12, 1922, Serial No. 528,654.. Divided and this application lel November lo, 1922.

To all whomz't may concer/n:

Be it known that WILLiAM E. `W1Nn, a citizen of the United States of America,residing at Toledo, in the county-of Lucas and State of Ohio, has inventedcertain new and useful Improvements in Door Arrangements for Railway Cars, of which the following is specification.

My invention 'relates to new and useful improvements in door arrangements for railway cars and more especially to the doors and locking means lof hopper cars, and the present application is a division of my previous application, filed January 12', 1922, for door arrangements for railway cars, bearing Serial No. 528,654.

The principal object of the invention is to provide a railway car having sloping sides and a sloping chute opening with a door` supporting mechanism attached to the sloping side of the car and arranged to occupy a minimum space, the mechanism being so connected to the car and Vso associated with the'door as to minimize the chance of its becoming inoperative.

Still another object of the invention is to provide a hopper door, as above described, and to provide pivotal hooks on the sides of the hopper which will fall by gravity into engagement with ledges formed on the door, the hooks being held tightly in position by dogs pivotally mounted to the rear of the hooks.

With rthese and other objects in view, the invention consists in certain novel arrangements and combination of arts as will be hereinafter more fully descri ed and pointed out in the claims.

Referring now to the drawings showing a' preferred embodiment of my invention,

Fig. l is a view in side elevation showing va fragmentary ortion of a ho per, the edge of one door an a pivotal hoo locking the door in its closed position,

Fig. 2 is an end view of the same,

Fig. 4 is a fragmentary diagrammatic view of a hopper, the dotted lines showing the sets of doors in their open position, and

Fi 5 is a diagrammatic view of two hopper oors and the stiiiening member extend- 1n across the same.

sloping chute l2. On the flared side of the y hopper is securely riveted a housing 2 in which is mounted a pivotal hook 3, its jaw extending downwardly. In this housing is pivotally mounted the dog 4: having the lug 5 formed at the rear thereof;

As will be noticed in Figs. 4 and 5, each hopper is provided with two sets of' doors which are shown in open position bythe dotted lines in Fig. 4. In Fig. 5 'thereis showndiagrammatically a centerl sill 6 and it will be seen that one door 7 of the set is to one side of the center sill while the other door 8 is on the other side of the center sill. .As the doors are identical, only one set will be described. These doors 7 and 8 will be hinged as at 9, while a transverse stiening member 10 is securely riveted to the two doors 7 and 8 and extends outwardly beyond the far side of each door as at 1l.

Secured by rivets or otherwise to the outer ends l1 of the stiiiening member l0 are the reinforcing angle irons 13, the Vupper legs of which are designed to be engaged and held by the jaws of the aforesaid hooks 3, it bejunction with the chute 12. The door open` ing, which is defined by the extreme edges of the said sloping side and the sloping chute, lies in an inclined plane extending 'across the car and sloping from a. point near the rail upwardly toward the transverse center line of the car. The door` such as 7 is arranged to lie against or parallel with the plane of the door opening. The car of the type illustrated is regularly7 provided with two of such hoppers and openings therefor arranged sidel b v side across the car,one at either side of the center sill construction 6. The door-stiii'ening member 10 extends across the car and connects the doors 7 and 8, and its ends extend outwardly beyond the sloping hopper sides l. The doorsecuring members, such as the hooks 3, toi

'inerme gether with the brackets 2 therefor, lie against and parallel withr the hopper side, so that these hooks engage the ends of the door-stilening member at acute anglesV therewith. The means for 'holding such doors'in closed positions has generall been located at the center of the car instea of at 'the sides of the car, and where the Same have been located a't the sides of the car it has generally been the practice to cause the hooks to swing at right angles with the plane of the door into engagement with the ends of the door stiil'ener.

This requires olf-set brackets upon which to pivot the hooks, andthe use of this type ot' bracket has not been wholly successful because of the remoteness of the pivot point of the hook from the sidesheet of the hopper, which tends to permit a looseness and some separating or' parts, frequently resulting either in imperfect operation or in inability" to hold the doors completely closed. This is especially true where the cars are sub jected to heating, such as may result from a load of freshly pulled coke, or hot ashes` the clearance ybetween the hook construction and the third rail and also between the projecting ends of the door-'stiffening members and the third rail is increased.

l The operation of the doors is exceedingly simple. Preferably one man will stand on each side -of the car; Agrasping the angles 13, which it is to be remembered are connected by a stifening member 10, the men swing the doors upwardly against. the hopper.

When these doors have reached their closed position, the pivotal hooks will drop by gravity, each engaging the upper leg of one of the angles 13, thus securely holding the doors in their closed position, after which the 'dogs 4 will be jammed against the rear of the hooks, thereby making it impossible for the door to accidentally open.

To open the doors, of course, the operation isv reversed. The lugs 5 on the dogs provide surfaces which may be hit with a. hammer to release the dogs, after which the hooks may be forced upwardly and the doors swung to their open position.

From the foregoing it will be seen that I have Vprovided an arrangement whereby two hopper doors may be moved in unison and will always be rigidly held in :gltheir spaced relation, the means for 'accomplishing this function also forming ledges which are engaged by locking devices secured to the hop-per in planes extending obliquely to the plane of the door.` The entire con# struction is one which is., relatively cheap, easily. applicablelto hopper ycars and eX- tiemely etlicient. Many slight changes might be made without in any way departing from the spirit and scope of the invention.

Having thu sy described my invention, what I claim as new and desir@l to secure by Let ters Patent isz* i l. A railway car having asloping side, y

member aliixed tothe door and having a pory l tion lying in a plane normal thereto, and a door securing means affixed to the car side, the same lying in a plane .parallelwith the slope of the car side and at an acute angle with the plane of the securing member eooperable therewith carried by the door.

2. ln a car provided with a hopper having a downwardly sloping bottom Wall and a side wall sloping inwardly from the vertical and forming with said bottom wall one of the corners of the discharge opening, and Aa pivoted door to close said opening; the combination with a member rigid with and projecting from one edge of the door across the edge of said side wall; of a latch pivotally mounted on said side wall to swing in a plane .parallel thereto, said latch being extended beyond the edge of said side wall and adapted to cooperate with-said proeeting member from the door; and means also mounted on said side wall adjacent thepivotal mounting of the la'tch, cooperable with said latch to loclr the latter in operative position.

3. In a car provided with a hopper having a downwardly sloping bottom wall and a side wall sloping inwardly from the vertical and forming with said bottom wall one of the corners of the discharge opening, and a pivoted door to close said opening; the combination with a member projecting from one edge of the door across the edge of said side wall, of door supporting means carried -by said sloping side walland adapted to releasably engage the said member projecting from the door, said door supporting means being inclined to the direction of the load imposed upon said door by the contents of -the car, whereby said door supporting means transmits to said slopin wall a force opposing outward bulging of said' wall. j

4. In a car provided -with a hopper having a downwardly sloping bottom wall and a side-Wallsloplng inwardly from the vertical in a downward direction and. Jforming with said bottom wall one of the corners ofthe discharge openingof the hopper, and a' swingingdoor for closin said opening; the l combination with a mem er carried by and projecting from one edge of the door across the edge of said side wall, of a latch member mounted on said side wall in a plane sloping inwardly from the vertical in a downward direction, said latch member being extended beyond the edge of said side wall and being adapted to cooperate with said member projecting from said door to supsidel port said dooragainst an opening movement.

5. In a car having a discharge opening and a swinging) door for-closing said opening, said door eing adapted to swing open under the inuence of gravity; the `combination with a door supporting member carried b the door and projecting beyond an edge tiiereof, of a door supporting member carried by the car body and adapted to cooperate with said member projecting from said door tosupport said `door against opening movement, one of said door supporting members being pivoted to swing in a plane forming an oblique angle with the plane of said door and sloping inwardly from the vertical in a downward direction.
