Although the door may hopper, the member secured to the door be'made of cast metal it is preferably formed being of greater rigidity than the member from a Single sheet of metal having a main engageable with the'hopper. body portion hand a plurality of inwardly Other and more specific features of the extending marginal flanges 7. It may'ad- 5O invention residing in advantageous forms, vantagepusly be hinged to the car by two hinge straps 8 secured to the outer face of the door and formed to receive a pin 9 mounted in lugs 10 formed integrally with the upper portion of the door frame.

A plurality of flexible strips 11 are arranged on the door in overlapping relation to its inner face and adjacent its free edges. Each strip preferably extends continuously along the edge of the door to which it is adjacent and the adjoining ends of the strips are preferably mitred as at 12. In the principal form of the invention shown in Figures 1 to 4 inclusive, of the drawings each of the strips 11 is in the form of a flexible metallic plate and has a portion 13 rigidly secured to the inner faceof the door by rivets 14. Extending inwardly from this portion of the strip is a plate portion 15 which is disposed at an acute angle to the inner face of the door and terminates in a portion 16 extending toward the door in spaced relation .to the adjacent flange 7 ofthe latter. The portions 16 of the stripsare so disposed that when the door is moved to closed position they will be engaged and thereby deflected by the portions of the hopper bounding the lading discharge opening, such as the flanges 4 of the door frame, so that they will intimately and positively contact with the latter when the door is closed.

By arranging the portions 15 of the strips so that they extend inwardly from the door at an acute angle thereto it will be appreciated that they will be subjected to the pressure of the lading within the car. This pressure acting on the portions 15 tends at all times to maintain the portions 16 of the strips in sealing engagement with the hop per. It will thus be appreciated that effective means is provided forming a seal between adjacent portions of the hopper and door to prevent the escape of fine lading not-- withstanding that the doors do not accurately fit the hoppers due to either improper mounting or deformation of the doors.

The form of the invention illustrated in Figure 5 issimilarto that shown in Figures 1 to 4, inclusive, but the sealing strips instead of being formed of-a single piece of metal are formed with two longitudinally extending members 17 and 18. The member 17 is formed of sheet metal and has portions 19 and20 respectively corresponding to portions 13 and 15 of the strips 11 shown in the principal form. of the invention. The por tion 19 is secured to the door by rivets 21 while the portion 20 extends inwardly from the door at an acute angle thereto.

The member 18 is of greater flexibility than the member 17 and is preferably formed from non-metallic material such as rubber belting and the like. It is preferably preformed by any suitable means such as a die or the llke so as to have angularly disposed portions 22 and 23. The portion 22 is it is not necessary to pre-form it before being secured to the member 17 but in this event such material will of its own accord assume the shape shown in Figure 5 of the drawings when the door is moved to closed position. v

The strip shown in Figure 5 being of the same configuration as the strips shown in Figures 1 to 1, inclusive, will function in precisely the same manner as those strips, that is, the pressure of the la-ding acting or the strip will tend to force the portion 23 thereof into more intimate engagement with adjacent portions of the hopper. By providing the strip shown in Figure 5 with the member 18 which is of greater flexibility than the member 17 it will yield more readily than the member 17 and thereby more easily conform to the surfaces of the hopper which it is adapted to engage.

In Figures 6 to 8, inclusive, the invention is shown as applied to the door of a hopper of a different construction from that illustrated in Figures heretofore described. In this form the hopper instead of being provided with a door frame is formed with a Z- shaped reinforcing member 25 ha ring a portion 26 disposed in a plane substantially parallel with that of the closed door forming a seat therefor. The door for closing the lading discharge of a hopper of thi type is preferably formed with outwardly projecting marginal flanges 27 which are adapted to be disposed closely adjacent to similar flanges 28 on the hopper reinforcing member. I

To provide eflicient sealing means for this type of door and hopper the strips are provided with portions 29 secured by riVets -K to the door, and portions 31 extending at acute angles to the inner face of the door which terminate in inwardly and laterally extending portions 32, the extremities of which are adapted to be interposed between the inner face of the door and the door seat portions 26 of the reinforcing member 25. The portions 31 of the strips being arranged so as to be subjected to the pressure of the lading within the car will tend to force or crowd the portions 32 of the strip into the space between the door and door seat portions and thereby form an effective seal against-the escape of fine lading.

In Figures 9 and 10 sealing strips of the character illustrated in Figure 5 are shown as applied to the type of door and hopper shown in Figures 6 to 8, inclusive. These strips are provided with two longitudinally extending members 33 and 34 respectively, the member 33 being of greater rigidity than the member 34 and being secured to the door. The member 34 is secured by rivets 35 to the member 33 and being of a configuration similar to portions 32 of the members 31 has a portion adapted to be interposed between the door and door seat portions of the hopper. As the member 33 has a portion inclined with respect to the door it will be appreciated that this strip will function in precisely the same manner as that shown in Figures 6 to 8, inclusive.

From the foregoing it will be-perceived that I have provided simple and efficient means for effectively sealing the lading discharge opening of railway hopper carsof various types for preventing the accidental escape of finely divided lading.
