' DISCHARGEDOOR-OPERATING MECHANISM.

Application filed December 24, 1915.

To all whom it may concern Be it known that I. GEORGE W. RISTINE, J12, a citizen of the United States, residing at No. 1716 East Fifty-fifth street, Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Discharge-Door-Operating Mechanism. of which the following is a specification.

This invention relates to railway dump cars, including that type known as a general service car, some types of which are illustrated and described in United States Letters Patent No. 791.348, granted to C. A. Lindstrom and John F. Streib, in which the bottom is partly or substantially conmosed of a plurality of discharge doors which are hinged along one edge, and which at their free edges are supported by the operating shafts which have heretofore been supported in stationary bearing members secured to the transverse members of the under-frame. and an object of the invention is to provide means for supporting the operating shafts independently of the trans verse members of the underframe, which means will take the place of or be auxiliary to the ordinary bearing members secured to the transverse members of the underframe.

Another object of the invention is to pro vide movable means for supporting a bodily movable discharge door operating shaft from the side wall of a car.

A further object of the inventionis to provide a discharge door operating mechanism, for railway dump cars, having a movable member adapted to be moved by the door operating shaft into or out of supporting position relative to said shaft.

With the above and other objects in view, the invention resides in the construction, arrangements and combinations of parts hereinafter described and claimed.

Referring now to the drawings in which like reference characters refer to like parts. Figure 1 is a plan view of a car embodying the invention, Fig. 2 is a side elevational view of the same, a portion of one of the side stakes being broken away to more clearly show a portion of the door operating mechanism; Fig. 3 is an enlarged cross sectional view taken on the line 3-3 of Fig. 1: F 4 is an enlarged detail side elevational view of a portion of the car. the side stake being om t d to m e y u trate the levee- Specification of Letters Patent.

tion; Fig. 5 is a sectional view taken on the line 55 of Fig. 4, the side stake being shown, and Fig. 6 is a sectional view taken on the line 66 of Fig. 4, portions of the side walls being removed to more clearly illustrate the invention. The description being confined. to that portion of the car which is illustrated, it will be understood that the opposite end of the car is in all respects similar to that which is shown.

Referring now in detail to the drawings, 1 indicates the center sill, 2 the end sill, 3 the bolster. and 4 and 5 the intermediate tra ns\-*erse members of the underframe, all of which may be of any desired construction and suitably connected.

6 indicates the car body which comprises end walls 7 and side walls 8. all of which are suitably connected. The side walls 8 are each preferably provided with a vertical upper portion 9. a downwardly and inwardly sloping intermediate portion 10, and a hori- Zontal lower portion 11, such horizontal portion preferably resting on and being secured to the end portions of the transverse members of the underframe. To stiffen the body of the car the side walls, at intervals throughout their length, are provided with stakes 12.

The lower edge portions of the side walls, as indicated at 13, and the upper edge por tions of the center sill and transverse members of the underframe define discharge openings in the car bottom, which openings are closed by doors 14 and 15. which are preferably hinged along their edge portions to bracket members suitably connected with the center sill 1.

To operate the discharge doors 14 and 15 and for the purpose of supporting such doors in their closed positions, shafts 16 are provided. In the embodiment of the invention as shown in the drawings. each of these shafts is rotatably and slidably mounted in slots formed in the members 17 which are preferably secured to the bolster and transverse members, and are also mounted in a -movable member 18 which is hereinafter To each of these,

more fully described. shafts is preferably secured a plurality of spirally grooved drums 19, to each of which a chain 20 is connected, the other end of the chain being connected to the free edge of one of the doors. preferably through the medium of a member 21 which is connected with a serrated shoe portion 22 which isadapted to engage with a serrated roller 23 ltl secured on the operating shaft, which roller may be integral with the spirally grooved drum 19.

Intermediate the transverse members 4 and 5 of the underframe a bracket member 24 is provided having a top portion which is preferably secured to the horizontal portion 11 of the side wall and having a side portion secured to one of the side stakes 12. This member is preferably provided with spaced vertical ribs 25 which are preferably integral with the top and side portions and are provided with notches 26 open at one end adapted to receive the shaft 16. These ribs 25 support the shaft 16 directly when such shaft is in the notches 26. Between the ribs 25, rollers 27 and 28 are mounted on pins 29 and 30, which pins are held against longitudinal .movement by cotters or other suitable means. The member 18 is movably mounted on the roller 28, and at its end portion 31 is preferably provided with a notch 32 in which the shaft 16 is rotatably mounted. It will be understood that if desired the notch 32 may be modified and the end portion of the member 18 formed in any other suitable manner to provide a bearing for the operating shaft. When the operating shaft is in the position as shown in the left hand portion of Fig. 3, and Figs. 4, 5 and 6, the upper surface of the end portion 33 of the member 18 will contact with the roller 27 and will thus support and prevent any down ward movement of the shaft 16.

Assuming the doors to be in closed position and it is desired to open them, the op erator by the use of lever 34 rotates the operating shaft 16 in the direction as indi. cated by the arrows in the left hand portion of Fig. 3 and Fig. 5, which causes the serrated roller 23 to engage with the serrated shoe member 22 on the doors 14 and 15, thus causing the shaft to move in a horizontal direction from its door supporting position, as shown in the right hand portion of Fig. 3 and in dotted lines in Fig. 5. It will be noted that the movable member travels horizontally with the shaft until the shaft drops within the notches 26 formed in the vertical web portions 25 of the member 24, at which time the movable member is subjected to a tilting movement, allowing such member to assume a position as shown in dot and dash lines in Fig. 5 of the drawings, and indi cated by the reference character A. To prevent further movement of the movable men"- ber 18 around the roller 28, a stop 35 is provided, such stop being preferably integral with the vertical web members 25.

When it is desired to close the discharge doors the operator rotates the shaft 16 in the direction as indicated by the arrow in the right hand half of Fig. 3 of the drawings until the chains 20 winding on the drums 19 have raised the doors to a position above the shaft at which time the continued rotation of the shaft and the wind-' ing of the chains thereon cause the shaft to move bodily a sufficient distance for the rollers 23 to engage with the shoes 22 of the member 21 to effect the final closing movement of the doors. As the shaft moves toward and under the doors the member 18 will be drawn by the shaft from its nonsupporting position as shown in dot and dash lines and. indicated by the reference character A in Fig. 5 to its supporting position as shown in full lines in this figure.

To stiffen the side wall 8 above the bracket 24, triangular members 36 are preferably provided which are secured to the stake l2 and to the sloping and horizontal portions 1.0 and 11 respectively of the side wall.

It will be 'iuulcrstood that if desired the men'ibers 18 which have been described as bcing secured to the transverse members of the underframe may be dispensed with and the movable member and bracket may be substituted at intervals throughout the length of the operating shaft for the support of such shaft.

In the drawings, the door 15 has been shown about twice the length of the doors 14, but it will be understood that if desired the door 15 may be of a length great enough to extend between the bolsters, or if desired all the doors may be made of equal length, or in other words, all the doors may be of substantially the same length as the doors 14.

I do not wish to be limited to the exact construction and arrangement of the parts of the door operating mechanism as described in the specifications, for it will be apparent to those skilled in the art to which this invention appertains that many changes may be made without departing from the spirit and scope of the invention, as set forth in the appended claims.
