June 24, 1930. w. E. WINE CAR noon MECHANISM Filed May 21, 1928 Patented June 24, 1930 PATENT GFFECE WILLIAM E. WINE, OF TOLEDO, OHIO CAR-DOOR MECHANISM Application filed May 21, 1928. Serial No. 279,480.

My invention relates to railway car door mechamsm for retaming in closed position a hinged door which is adapted to swing to open position under the influence of gravity. The principal object of the invention is to provide, in combination with suitable door mechanism, simple and efficient means for sustaining the door in a position for clampening the discharge of lading, such as ballast and the like, from the car.

A primary feature of the invention resides in providing the door mechanism with a member carried by the cover plate overlying the outer face of the hook, the member being 1 arranged to engage a portion of the door, when the latter is released from the hook, to arrest opening movement of the door and to sustain it in a position for dampening the discharge of lading from the car.

Another feature of the invention consists in providing the car door supporting mechanism with a member formed so as to be connected to the fulcrum extension of the cover plate which overlies the hook, the opposite end of the member being cooperable with an apertured portion of the door arm to arrest opening movement of the door, when the latter has been released from the hook, so as to sustain the door in a position for clampsuing the discharge of lading from the car.

Another feature of the invention resides in fashioning a member so that it may be removably connected to portions of the car door mechanism to sustain the door in a position for dampening the discharge of lading from the car.

Other and' more specific features of the invention residing in advantageous forms and relations of parts will hereinafter appear and be pointed out in the claims.

In the drawings illustrating preferred embodiments of the invention:

Figure 1 is a fragmentary view of a car hopper and its coacting door illustrating the invention applied thereto, the door being shown in fully closed position.

Figure 2 is a view of corresponding parts of the car construction, the door being shown in a position for dampening the discharge of lading from the car.

Figure 3 is a sectional view taken on line 33, Figure 1. v Figure at is a slightly modified form of the invention, the door being maintained in a position similar to that shown in Figure 2, the adjacent parts of the hopper being omitted.

While the drawings illustrate a single hopper and the adjacent edge of a coacting door, it is to be understood that the construction is preferably duplicated on the opposite side of the car and that the door illustrated is but i one of the door sections which are disposed 011 opposite sides of the car center sill and which are connected by a spreader or stiffening member, so as to swing as one.

In the drawings, 1 indicates the side sheet of the hopper and 2 the bottom or slope sheet thereof, the outer edges of these sheets form ing the lading discharge opening. A metal door 3 is preferably employed for closing the discharge opening of the hopper, the door being hingedly connected to the car body in a manner (not shown) such that it will swing to open position under the influence of gravity; The door spreader or stiffening member,

indicated at 4, is formed with a plurality of flanges 5 and 6, respectively, the flange 5 being secured to the outer face of the door by rivets 7, while the flange 6 projects outwardly therefrom. The end of the spreader which projects outwardly of the side edge of the door constitutes an arm, the procumbent flange of which is cooperable with the portion of the door mechanism carried by the car body to support the door in closed position.

Pivotally mounted upon the'side sheet 1 of the hopper is a hook member 8 having a plurality of

ledges

9 and 10 which are respectively engageable with the outer end of flange 5 of the door arm to support the door in partially closed and in fully closed position.

Overlying the outer face of the hook is a cover plate 11 fashioned with a plurality of inwardly projecting bosses 12, 13 and 14, re spectively, which are apertured to receive attaching rivets 15. Washers or "ferrules 16 as a pivotal support forthe hook 8 while the boss 12 affords a'pivotal support for a rotatable cam 18 employed for locking the hook in door supporting position to prevent accidental opening movement of the door.

Projecting outwardly from tne cover plate 11 is an apertured extension 19 which primarily serves as a fulcrum for a removable bar or lever (not shown) utilized for obtaining a mechanical advantage to force the door from a position of partial closure to a position of final closure. The extension 19 may be suitably reinforced by a rigi'difying web 20. Operatively interposed between the door and the hopper is a member 21 which serves to sustain the door in an intermediate open position, so that the discharge of lading such as ballast and the like from the car, may be dampened. This member 21 extends through the aperture formed in the cover plate extension 19 and through the aperture 22 formed in the outwardly projecting flange 6 of the door arm. The ends of the member 21 are oppositely bent to form hook-

shaped portions

23 and 2 respectively, the hooked end 23 serving to supportingly connect it to the cover plate 11. When the door is in fully closed position the member 21 loosely depends through aperture 22 of the door arm as is clearly shown in Figure 1. After the hook 8 has been rotated from engagement with flange 5 of the door arm, the door swings toward open position under the influence of gravity moving the member 21 outwardly until its hooked end 24 engages a portion of the door arm bounding the aperture 22 thereofas illustrated in Figure 2. Thus, further opening movement of the door is prevented and it is sustainedin a position such that the flow of lading from the car is dampened.

The member 21 is constructed so that it may be employed without necessitating any substantial modification of'the type of door mechanism illustrated in the drawings, and it is also designed so that it may be readily detached from the mechanism when it is desired to permit the door to swing entirely open rather than support it in an intermediate open position. j

Upon referring to Figure 1, removal of member 21 is accomplished by raising it vertically upward until the lower outer end of the hooked portion 23 passes above the adj a cent portion of the cover plate extension 19. The hooked end 23 may then be moved inwardly toward the hopper permitting the ends thereof are so proportioned and ar-' ranged. with respect to the associated parts of the door mechanism, that accidental displacement thereof is practically impossible.

In the modified form of the, invention illustrated in Figure 4, the device enabling dampening of the discharge of lading con sists of a U-shaped member 25, the opposite ends of which are secured to the hook 8 by a pivot rivet 26. Connected to i the U-shaped member 25', by a plurality of links 27, is a headed member 28 preferably of T-shape. hen the door is in closed posi tion the device depends loosely within the aperture of the door arm in a manner similar to that of the member illustrated in the other figures of the drawings. Upon release of the door from its supporting hook, it swings toward open position under the influence of gravity, being arrested? in its opening movement by the upper surface of the member'28 engaging'with the lower surface of portions of the door arm adjacent its aperture. The proportions of the member 28 are such that it may be disconnected from the door arm so as to permit the door to swing from closed position to fully open position. This disconnection maybe accomplished, when the door is in fully closed position, by rotating the member 28,through ninety degrees and then moving it vertically upward.

From the foregoing it will be appreciated that a most etficient yet simple and rugged means has been devised enabling the doors of railway cars to be maintained or supported in positions for dampening the discharge or flow of ballast and the like from railway care. As ballast is distributed along the right of way While the car is being moved thereover, it will be seen'that, by employing the device disclosed, the ballast may be deposited over a much greaterarea than would be the case when the, door is permitted to assume an entirely open position.
