5 bottom doors hinged on a horizontal line or lines transverse to the length or course of travel of the car. I

In such cars heretofore manufactured, provlslon is made for holding the door or doors in the closed position and for releasing the' doors to allow them to turn downward on their hinges to permit discharging the lading by gravity.

Among such means a latch mechanism has been used for engaging therear endof the door, if there was only one door, and to engage the rear end of the rear door when a plurality of doors were made a part of the car.

The object of this invention is to provide a stronger and more effective mechanism for engaging the rear end of such a door when that door has been raised approximately into a the horizontal, closed position manufactured, reference is here made to-Letters Patent of theUnite'd' States,No. 1,512,- 059, granted to Hugh WV. Sanford, Oct. 21, 1924, for railways. In that patent,'an arm 39 extends rearward from the rear edge of the door and is engaged by hooks on downwarddirected arms which are supported to be moved pendulum-fashion transversely tothe length of the car.

In this application, my improvement is shown applied to such a car having only one adjacent the line,-44;

As an example of such a car heretofore 1 Fig. 6 is a longitudinalupright section on fhfe line, 6-6, of Fig. 4:, looking towardthe e t; r

Fig.- 7 is a detail plan of the oscillating arm, shown in Fig.5; i

Fig. Sis a longitudinal, upright detail section illustrating the support for the forward end of the door; 1 Fig. 9 is a rear view of the structure shown y W l Fig. 1 0 is a cross section on the line, 1010, ofFig.7. Referring to said drawings, A, A are track rails, resting on cross ties, Al. B, B are ordinary car wheels applied to the ends of the axles, C, G, which extend transversely across the body of the car. D, D are side walls. E, E are end' walls of the car.

G is a shaft extending across the ca-rbo'dy horizontally and parallel to the innerflface of the forward end sill of thecar and having its ends resting in the side walls, D, 'D. I

H is the'bottomdoor. This extends-beneath the axles, C, C and fills the space 'between the side walls. The forward end of thedoorextends to the shaft, G, and is se cured thereto by hinge straps, H1, surrounding said shaft and riveted to the bottom of the door. At each side edge, said door has an upward-directed flange, H2, which serves tostiffen the door and to allow the door to extend below the lower edges of the side walls. The flanges, H2, extend only near enoughto the walls, D, to allow free up and down movement of the door. The body of the door is low relative tothe height of its up-curved ends. v A

The drawings show a bar or plate, H4, applied to the lower face of'the door, along the rear edge of the door, and secured to the.

D, of each of said walls is upright, and has a lower outward-directed flange, D2.

At therear end of the door a bearing, I, is placed against the outer face of the adjacent part, D, of each'side wall and near the flange, D2, and secured to said wall by bolts or rivets, I1. Each side wall is apertured opposite the bore of the adjacent bearing. A bearing bushing, I2, extends through the hearing, I, and the adjacent part of the wall, D, and has at the inner face of said wall an annular flange, I3, resting against said inner face- The interior of said bushing is poly onal in cross section (the drawings show it square). in the hearing, I. 1

A rock-shaft, J, of polygonal (square) cross section adapting the shaft to engage said bushings extends from one bearing, I, to the other and into the bearing bushings. At the right hand side of the car, said shaft extends through the bearing, I, and supports a hub, J1, said hub surrounding said shaft and fitting the four sides of said shaft and fixed thereon by keying or similar means. On said hub is an arm, J 2, reaching obliquely outward away from the car and forward. 7

(Figs. 1, 4, 5 and 7). The outer face of said arm is channeled and receives a bar, J3, rigidly secured to said arm by bolts or rivets, J4. The outer end of the bar, J3, is bent horizontally away from the car to form an arm,

J5, which is to be engaged by a stationary cam along the track, as will be described furtheron.

At each hearing, I, a washer, J6, surrounds the bearing bushing beside'the hearing, I. At the outer face of the washer, a cotter, J7, extends through the bushing and the shaft, J. Thus each bushing is held against endwise movement toward the car, while the flange, I3, on the bushing holds the bushing against movement away from the car. By extending the cotter through the shaft, the shaft is held against endwise movement in the bushing, I3, and the bearing, I. Because the shaft is four-sided and the bushingsare fitted to the shaft, the shaft can not rock independently of the bushings. l/Vhen the shaft rocks, the bushings rock with the shaft, the bushings rocking in the bearings, I.

The common axis of the bearings, I, and the shaft, J, is in a horizontal plane which is lower than the wearing plate, H4, on the door, H, and said axis is far enough rearward in said plane to make space between the shaft, J, and the wearing plate, H4, for a hub, L1, and a cam-form lateral extension, L, resting on said shaft, said hub surrounding and being fitted to the faces of said shaft, J, for seating said hub immovably on the shaft.

One such extension isshown placed near Between these extensions other hubs, L1 and Said bushings are free to turn plate, L6.

lel to the adjacent face of said plate, H4,

when the door rests on said extension. each side of the face, LS, the face of the ex tension has a rounded or curved part, L4,

to meet the faces, L5, which extend tothe hub, L1. A wearing plate, L6, of approximately uniform thickness is seated over the faces,'L3 and L4, and a partofthe forward face, L5, of theextension.

When the door is, in the closed position, the plate, H4, rests on the part, L3, of the To release the door, the shaft, J, is turned contra-clockwise as viewed in Figs. 1 and 5 and clockwise,as shown in Fig. 6, to turn the extension rearward to allow a clear downward path for the end of the door. I

Flattening'the extension face is for the purpose of bringing the support of the wearing plate, H4, nearer the axis of the shaft than is the adjacent forward part of the extension. This difference in the facing of the extension prevents the extension from turning rearward without lifting the door and the load of coal or other material supported by the door. Thus provision. is made for automatically keeping the extension in engaged position until it is desired to release the door by forcibly rocking the shaft, J. In practice, I have found that flattening'the face, L3,- of the extension to a depth of oneeighth of an inch is sufficientto make the desired degree of engagement with the door to keep the cam from turning excepting through turning strain applied to the shaft, J.

An angle bar, E1, is applied to, the rear part of the lower face of the wall, E, close to the position of the rear end of the door when the door is closed. One flange of said bar is placed flatwise against the wall, E, and isriveted to said wall; The other flange of said bar extends rearward and downward from the upper part ofthe other flange. Thus the bar is applied to the end wallas a means of stiffening the lower edge of said wall. At the same time sufficient sheltered space is left under and behind said wall to receive the extension or extensions, L, when the door is to be released. It will be noted that when the door is closed and the car body isfilled with coal or other material,

coal from resting on the extensions.- This extension-receiving recess or chamberis to be kept in mind when studying the operation of this mechanism. It is to be understood that, when stiffening the end wall is not desired, the angle bar, E1, may beomitted. But, in such case, the adjacent part of the wall, IE, will afford a sheltered space for the extensions, L. I

At the tipple or other place for discharge, a stationary lifting cam, M, is seated on cross ties, A1, beside the track, inthe path of the outer end of the horizontal arm, J5, of the bar, J 3, so that during forward movement of the car, the arm, J 5, will meet said lifting cam and ride upward on said cam, whereby the rock-shaft, J, is given a partial turn contra-clockwise, as viewed in Fig. 5, whereby the extension, L, is turned rearward out of engagement with the end of the door, H, and into the cam recess-or chamber above described.

wall, D1, (Figs. 1 and 5) in position to allow the arm, J5, of the bar, J3, to reach outward through said stirrup into position to meet the lifting cam, M. The stirrup extends downward into position to arrest the downward movement of the arm, J 5, when the extension, L, is in its operating position. The rear, upright part of the stirrup is in position to limit upward movement of the arm, J 5, the purpose being to prevent said arm from rising much more than is needed to release the lifting cam, M.

The weight of the arm, J5, and the bar, J3, and the hub arm, J2, is intended to be sufficient to cause downward turningwhen the arm, J5, is free from the lifting cam, M. That freeing is to be so timed as to occur after the rear end of the door has moved downward beyond the extensions, L, and the hubs, L1.

After the material has been discharged from the car and the door. has become free to be again lifted into the closed position, that lifting may be accomplished manually or by any suitable means located along the track, as, for example, a cam rail located between the track rails as disclosed in Letters Patent of the United States, No. 1,268,390, granted to Hugh W. Sanford, June 4, 1918. While the rear end of the door is being pushed upward it will bear against the face of the plate, L6, on the extensions, L3, and turn said extensions backward until the end of the door has passed said extensions. Thereupon the weight of the arm, J5, and the bar, J3, and the hub arm, J2, causes movement of said membersdownward until the arm, J 5, engages the lower part of the stirrup, E2, that movement causing the rocking of the shaft, J, far enough to bring the extensions, L, into operating position against the lower face of the wearing plate, H4, on the applied as shown in Fig. 4. c h

It has already been stated, that heretoforefi ibearingspand havingan upward extension 'doorf Thus the'door is again in the locked receiving the hub, J 1, the arm, J2, and bar,

J3, for rocking the shaft, J. It is to benoted that this shaft is adapted to be reversed to make it project from the left hand hearing, I, and there receive the C hub, J1, the arm, J2, and bar, J3. .Forthis no change need to be made in the shaft orbar. The washers,iJ6, and the cotters, J 7.,are to'be in a similar car, a hook arm, supportedpendulun1-fashion above the rear end of the door, brought its hook into engagement with an arm extending rearward on the rear edge of the door. In that structure the arm is 21 suspension or hanger member on which the i rear door is hung or suspended. A stirrup, E2, is suspended from the body In my improved form, each extension, L2, extends upward from the shaft, J, and serves as a prop for supporting the end of the door; and saidprop is turned rearward to disengage it from the door, whereby the'door is made free to fall by gravity.

For further contrast with prior art, and to emphasize the nature of the structural combination which I have formed, attention is invited to the fact that the hook arm supported pendulum-fashion, could not be subs'tituted for the rockable prop structure forming a part of my improvement. The slanting end wall, E, placed rearward of the rear end of the door precludes placing the pendulumform hook to serve for engaging the door. To give the car more capacity, it is desirable to slant each end wall as much as will permit sliding of the coal when the door is down for discharge of the coal.

In the foregoing description, I have stated that 'a plurality of hubs and extensions may be placed to engage the door. When that is done, the rockshaft and the hubs and extensions constitute a rocking member making extended engagement with the rear part of the door.

While my drawings show only one bottom door, it is to be understood that my invention is applicable when there are several bottom doors. In a car of large capacity, a plu rality of doors are ordinarily desirable. V
