To all whom itmay concern:

Be it known that I, WILLIAM E. WINE, a citizen of the United States, residing at T0- ledo, in the county of Lucas and State of Ohio, have invented certain new'and useful Improvements in Car Doors, of which the following is a specification.

This invention relates to a door for railway cars or the like, and has among its objects to provide an improved form of door which will be relatively strong and economical of construction. Another object is to provide a door having formed therein a stiffening arrangement, and also a door having sealing means formed therein. Other objects are to provide a door of economical construction and improved arrangement of hinges and of door supporting members.

With such objects in view, the invention consists'of the formation, combination and arrangement of parts as will be herein described and particularly as pointed out in the appended claims.

In the accompanying drawings, which show a preferred form of the invention, Figure 1 is a vertical longitudinal section through the hopper portion of a car of the ordinary twin hopper type, having applied thereto a door constructed in accordance with the principles of the present invention. It will be understood that the door is applicable to any type of car and may be formed in a variety of styles. The twin hopper type of car. as selected, is convenient for a showing of the invention. Figure 2 is a view of the outermost face of the door, as-shown in Figure 1, this view showing the door hinges and door-supporting beam secured thereto. In doors of the type selected for showing in the present embodiment, it will be understood that a pair of doors is usually supplied and these are connected by means of the door spreader. In the present drawings, but one door is shown and the door spreader is shown as broken. but it will be understood that in such an embodiment a similar door is provided for the hopper at the opposite side of the car and the door spreader will serve in the usual manner to connectthe doors. I

Referring to these drawings, the hopper side of the car is indicated at 1, and at 2 is indicated the hopper floor plate or chute plate. A transverse connecting plate is indicated at 3, and to this is shown a body hinge 4, which is secured to the car body as by means of the rivet 5. Such construction is well known in the art.

The door 6 is adapted to close the opening of the chute, this opening being defined by the margins of the side plates, such 1, and the floor plate, such 'as 2, also by the lowermost extremity of the cross plate, such as 3. Formed entirely around the margins of the door and slightly removed from the edges of the door, there is a continuous corrugation 7. This corrugation is adapted to stiffen the door plate, and also to form a sealing means. The general plane of the door plate is disposed against the face of the hopper discharge opening, and the corrugation 7 extends inwardly of this opening, so that iteffectively seals the opening by constituting an inturned flange for the entire periphery of the opening. The flat portions 8 of the door plate, which lie outside of the lines of the corrugation 7, preferably lie in the same plane as that of the general plane of the door plate, and these edges constitute flanges which abut directly against the edges of the plates, which define the hopper discharge opening. Y

Thedoor spreader 9 may be of the customary type formed ofa channel member and this, with a door constructed with the principles of the present invention, may extend continuously across the outer face of the door without interruption as is the case where corrugations are formed outwardly of the doorplate, or where marginal flanges are outstanding from the door plate. The door spreader is secured to the door as by means of rivets 10, and. it will be noted that some of these rivets are disposed at either side of those portions of the corrugation 7 over which the door spreader passes. This attaches the flanged portions 8 of the door to the central portion of the door plate and forms a reinforcement across the corrugation. This is of special importance near the outer edges of the door, as the door is often held in closed position by door-supporting means such as the hook 11, which is arranged to engage a suitable member on the door, or on the door spreader nearthe outer edge of the door. The hook 11' in the present embodiment'is shown as pivoted to the hopper side 1 at 12, and may be swung about the pivot 12 into or out of engagement with the angle iron 13, which is secured to the door spreader for this purpose. Rivets 1a and 15 may also extend through the one leg of this angle iron and through th'edoor plate, the rivet 14; being located outside of the corrugation 7, and the rivet 15 inside of the corrugation 7, thus constituting an additional tie across the corrugation in this vicinity. The other leg of the angle 13 may be secured to the web of the channel spreader 9 by means of rivets 16. The doorhinges 17 are shown as attached to the outer face of the door and these extend from the top of the, door down to the vicinity of the door spreader 9. They may be secured to the door by means of rivets l8, and it will also be noted that one of the rivet-s, 18 for each of the hinges lies above the corrugation 7, and others thereof lie belowthis corrugation, thereby forminga tie across the corrugation to transmit the vertical forces. The rivet 15. which passes through the angle iron 13 and through the door plate, may also pass througl' the lowermost end of one of the door hinges, thus securing all the parts to gether.

Doors constructed in accordance with the principles of this invention will in general conform to the shape of the discharge-opening and the corrugation will extend around I the periphery of the door plate following the line of the discharge opening, as shown in the present embodiment. The corrugated portion of the plate will in general fall inside of the plane of the discharge opening, as, heretofore explained. The door may be formed of a single sheet of metal and the usual appurtenances, such as the hinges and the door spreader, may be applied thereto in a manner to provide such stiifeners as are peripherical corrugations.

' I'have thus described an embodiment of my invention. Other embodiments are contemplated within the scope of the appended 1 claims without departing from the spirit thereof.

What is claimed is: 1. A. door forthe discharge opening of a railway car, the same being formed of a plate of'metal conforming in general shape to the outline of the discharge opening, a corrugation formed around the periphery of the door plate, the same following the lines of the discharge opening, the general plane of the door plate "being arranged when closed, to coincide substantially with the face of the discharge opening, the cor-rugated portion of the same extending inside ofr-the plane defining the face of the dis- '-charge opening in a manner to constitute therewith a sealing means.

'2. A door for the discharge opening of a railway car, the same embodying a plate of sheet metal arranged to lie, in closed position, in the plane defining the'face of the 'discharge opening, a peripheral corrugation formed around the plate, the same substantially defining the inner edges of the discharge opening and extending inwardly of the face of thedischarge opening and of the general plane of the door plate and arranged to provide, in conjiinction with the walls of the discharge opening, a sealing means.
