HUGH W. SANFORD, OF KNOXVILLE, TENNESSEE RAILWAY CAR Application filed April 19,

This invention relates to cars for hauling minerals, such as coal at mines, and similar material; and the invention relates particularly to such cars in which provision is made for emptying the car by discharging the material downward through the bottom of the car by displacement of the bottom.

Such cars have heretofore been made with a bottom consisting of a'plurality of doors opening and closing automatically and each havin one end hinged to the car body on an axial ine which is horizontal and transverse to the length of the car and the Group of doors being associated with releasalile means for holding them in the elevated or closed position.

The object of this invention is to so construct such cars as to give them more capacity for holding material relative toa given width 2o of track gage and to/afford more space in the bottom opening for the discharge of the material. There are many mines in which the track gage is narrow relative to the quantity of material it is desirable to haul in a car of the length which is feasible in view of the curves in the track. Furthermore, because frequently the material is in large pieces or lumps and the danger of those pieces lodging in the discharge opening and stopping the 3o discharge from the car, it is desirable to make the discharge opening larger than heretofore relative to a given track gage, even if such enlarging is no more than a few inches. For even such a small increase in size of the discharge opening will serve to allow the passing of many large pieces which would otherwise become lodged and stop the discharge.

With these objects in view, I have produced such a car in which, among other features, there is the leading feature of axles separated far from each other and entirely out of the range of the discharge opening, track wheels, axles extending through said wheels and having their outer ends supporting the car body. Thus a combination is made in which there is a wide separation of the side sills or similar members which form parts of the door structure at the sides of the car body and the space to be occupied by a plurality of automatic hinged bottom doors 192s. serial No. 271,269.

is made wider than could be the case if the body supports were at the inner sides of the wheels; and said space is made longer by reason of the larger distance between the axles.

In the accompanying drawings,

Fig. 1 is a side elevation of the rear half of a car embodying my improvement;

Fig. 1a is a side elevation of the forward half of the same car;

Fig. 2 is a front end view looking at the car from the right as shown by Fig. la;

Fig. 3 is a rear end View looking at the car from the left as shown by Fig. 1;

Figs. 4 and 4a together form a horizontal section on the line, 4 4, of Figs. 1, and 1a, Fig. 4 showing the left hand part and Fig. 4a the right hand part of the machine;

Figs. 5 and 5a. show an upright section on the line, 5 5, of Figs. 2, 3, 4 and 4a, looking in the direction of the arrows, Fig. 5 showing the rear part and Fig. 5a showing the forward part of the machine;

Fig. 6 is an upright section on the line, 6 6, of Fig. 1a, looking toward the left;

Fig. 7 is a horizontal section on the line, 7 7, of Fig. 6;

Fig. 8 is an upright section on the line, 8 8, of Fig. 6, looking in the direction of the arrows;

Fig. 9 is a horizontal upright section on the left hand part of the line, 9 9, of Fig. 4;

Fig. 10 is an upright, transverse detail section on the line, 10 10, of Fig. 1, looking toward the left;

Fig. 11 is an upright, transverse section across a side edge of one of the doors.

Referring to the drawings, it is to be noted that the right hand end of the car, as shown in Figs. 1a, 4a, a'nd 5a, is the forward end of the car.

A, A, are the track wheels. A1 are axles supported by the wheels. The axles extend through the wheels and their outer ends are in the form of journals, A2, resting in axle boxes, A3, which are guided for up and down movement in pedestals, as willbe described further on.

At each side of the car body is a metal side sill, B. In the form shown in the drawand extends inward to and then downward.Y

in a plane which is upright and parallel to the sill plate, B1, and far enough from the plate, B1,'to make room for the Wheels, A. The plates, B4, extend downward below the axles and are notched to make room for the axles.

The upper edge of each lower body side plate, B4, meets the upper body side plate, B5, and is suitably secured thereto. That plate is shown as being upright and extending to the height of the ear body. Adjacent each axle end, two angle bars, B6, extend over and are secured to the outer face of the wall, B5, and a part of the slanting portion of the lower body side plate, B4, tothe slanting flange, B3, of the sill plate, B1, and then downward in an upright position far enough from the sill plate to make room for the pedestal, A4. The upper end of the pedestal, A4, bears against the lower face of the adjacent side sill and thus supports said sill. The pedestal is secured to the angle bars B6, and to the sill plate, Bl, and the lower flange of the side sill, B, by means of rivets or bolts. The axle box, A3, surrounds the journal, A2, and extends horizontally through the pedestal, the pedestal having upright faces forming guide ways permitting up andv down movement of the axle box. (Figs. l, la, 6 7 and 8). Between the axle box, A3, and the upper horizontal part of the pedestal, A4, is a spring, A5, which serves as a cushion between the axle box and the pedestal. The wheels and axles constitute supports for the body. Thus we have under each end of the body a wheel and axle support.

The ends of the side sill, B, project beyond the end edges of the sill plates, B1. Between those ends is the horizontal end structure, C, consisting of the rectangular frame formed by the side sill and those structures. Each end structure has an outer metal channel, C1, and an inner metal channel, C2, the outer channel extending horizontally from one side sill to the other and having each end bearing against the inner face of the adjacent side sill at the end; of the sill, while the channel member, C2, similarly meets the inner faces of the side sills farther toward the body of the car. The drawings show it near the adjacent upright edge of the channel late, B1. The ends of the channel mem er, C2, are secured to the side rails by upright corner angle members, C3,

which have their flanges resting against the back face of the channel member, C2, and suitably secured thereto as by means of rivets, the other flange resting against the inner face of the side sill and secured thereto in the same manner. The drawings (Figs. 4 and 4a) show that flange of the corner angle member filling the space between the channel member, C2, and the adjacent edge of the side sill plate, Bl. A top plate. C4, extends from one 'side sill to the other' and from one channel plate to the other and rests on the upper flanges of the side sills and the upper flanges of the channel members and is secured to said flanges by rivets. A similar lower plate, C5, is applied in the same manner to the lower flanges of the side sills and the angle members. On the middle longitudinal line of the frame consisting of the vside sills andthe end structures, a coupling member, C7, extends through the channel member, G1, and the channel member, C2. Said coupling member is shown as being formed of two pieces of strap metal lying upon each other until they reach through the rear channel, C2, Where they are spread to bear against the inner face of the channel member, C2. The outer end of the member, C7, is apertured to receive any other coupling member', for example, a clevis which supports a link or similar member connected withanother car, as is already well known and need not be here illustrated and described in detail. Filling bodies, C6, oc cupy the spaces between the plates, C4 and C5, and the channel members, Cl and C2, and the coupling member, C7, and are secured to the coupling members and the plates, C4 and C5, by bolts or rivets.

At the front end of each side sill, B, a metal strap, C8, is laid against the outer face of the upright web of the sill and secured thereto by rivets. Each such strap extends horizontally forward away from the end of the sill and obliquely toward the extended middle longitudinal line of the ear. To each such end is attached a clevis, C9, to which a chain or any similar coupling device may be attached for connection with the adjacent end of another car. At the rear end of the car other straps, C8, are similarly applied, but left straight. Thus three coupling devices are applied to each end of the car.

In approximately the upright, transverse plane extending across the car perpendicularly to the length of the car and through an angle bar, B6, at each side of the car, an upright reinforcing metal strap, B8, is applied to the outer face of each body side plate, B4, and suitably riveted thereto. These straps, B8, extend from or near the lower edge of the plates, B4, upward to or nearly to the sill plates, B1.

From the upper edge of each upper body side plate, B5, a body end plate, B9, extends tending over the adjacent axle, A1, and along the lower body plates, B4, and a short distance across the axle.- The lateral edges of these body end plates are secured to the body plates, B4 and B5, in any suitable manner. Near the lower edge of each bod end plate, B9, a reinforcing channel mem er, B10, is applied horizontally against the outer face of the end plate and suitably secured thereto as by means of rivets. The forward body end plate, B9, bears against and is riveted to a metal stra B11, which vrests on and is riveted or bo ted to the upper part of the adjacent end structures, C.

The rear end plate extends farther away from the rear axle, A1, than is the case with the forward end plate relative to the forward axle. Thus additional space is afforded between the rear axle and the rear end structure for the latch mechanism which serves to hold the, rear door as will now be described.

The releasable bottom of the car consists of a rear door, D, and a forward door, E. These two doors together extend across the space between the lower edges of the body side plates, B4, and the lower edges of the body end plates, B9.

Each door is bent or curved downward between its ends, whereby the depth of the car is extended. The forward end of the rear door is hinged to a transverse shaft, D1, which has each endextending through the adjacent body plate, B4, and a bearing, D2, secured to said plate. A nut, D3, is threaded to the outer end of the shaft and engages the adjacent end of the bearing, D2. The inner end of the bearing is engaged by an annular shoulder, D4, formed on the shaft (Fig. 10). At or near each side edge of the door, D, an angle bar, D5, is applied to the under face of the door, one flange of said bar being laid :iatwise against the lower face of the door and riveted to the door and the other flange being directed downward. This angle bar extends nearly to the shaft, D1. The body of the door extends above and across the shaft, D1, and is curved to be concentric with said shaft. (Figs. 1, 4, 5 and 9.)

Any desired number of upper hinge members, D6, (Fig. 9) extend across the shaft, D1, below the door body and have their forward ends bent to lie iatwise against the lower face of the door. These ends are riv-l eted to the door. Where these members cross the shaft, D1, they are curved downward to partially surround the shaft. Above the shaft, a spacingv sleeve, D7, is placed between the member, D6, and the lower face of the door. A rivet.` D8, extends through the spacing member, D6, and said spacing sleeve and the adjacent part of the door and bind said members to each other.

Below each member, D6, a hinge member,

D9, extends across the lower face of the shaft,

D1, and is curved to bear against said face and has each end bent to bear atwise against the hinge member, D6. Those ends are se- 'glred to the member, D6, by means of r1vets,

The rear end of this door, D, is normall held in the upper position by means of latc mechanism which will now be described.

At the rear end of the door a rod, D11, extends horizontally from one upright flange of the angle bar, D5, to the corresponding flange on the other angle bar, D5, and is supported by said lian es. The ends of said rod are seated in said anges. Thus said rod is permanently xed to the door.

` Above and a little forward of the rear axle, A1, a latch shaft, F, extends from one side sill to the other and through each side sill. On each end of the axle is a retaining sleeve, F1. An arm, F2, surrounds the left hand end of said shaft and is fixed thereto and extends rearward and obliquely downward (Figs. 1, 3, 4 and 5). This arm is to be arranged to be lifted by a stationary cam placed adjacent the dumping or discharging station as shown and described in my Letters Patent of the United States, No. 1,268,390, dated June 4, 1918. When said arm meets such a cam, the arm is lifted, whereby the latch shaft, F, is rocked or partially turned. On said latch shaft, F, are fixed two latch arms, F3, which are directed downward behind the latch rod, D11, and near each end of said rod. On the lower end of each arm, F3, is a forward-directed hook, F4, which is adapted to reach under and normally support the latch rod, D11, when the door is in its upper or closed position. On the forward lower part of the hook is a slanting face, F5, against which the latch rod, D11, presses to push the hook rearward when the door moves upward into the closed position.

Each arm, F3, extends upward and rearward from the shaft, F. On the upper end of said arm is a clevis, F6, to which is coupled the forward end of a coiled tension spring, F7, the rear end of which is coupled to a tension bolt,

F8, which extends through a bracket, F9,

F3, and the hooks, F4, in the forward position for maintaining the support of the latch rod, 'l D11, whereby the door is held in the closed position. at the side of the track and is raised, as above indicated, the arm,

are forced rearward, whereby the latch rod: D11, is released from the hooks and the door F3, is tilted againstvthe d strain of the springs, F7, and the hooks, F4

When the arm, F2, meets the cam ,125

is made free to turn downward in response to -the action of the ,weight of the door and the material resting thereon.

Immediately at the rear of the forward axle, A1, is the forward door shaft, E1. This shaft is horizontal and perpendicular to the length of the car and extends through the adjacent lower body side plates, B4, and through the adjacent reinforcing metal straps, B8. The forward edge of the forward door, E, is hinged to said shaft in any desired manner. The drawings show four metal straps, E2, folded around the shaft and upon each other and laid atwise against the lower face of the door and secured thereto by means of rivets. The rear end of this door normally rests on the curved forward part of the rear door, D. But the forward door does not extend rearward beyond an upright plane which passes at the front of the rear door shaft, D1. Thus the rear end of the door, E, may pass downward in front of the shaft, D1, when the rear door, D, turns downward to bring its forward edge out of engagement with the rear edge of the forward door. Thus the forward door, E, becomes free to turn downward immediately upon the partial downward movement of the rear door, D, after the hooks, F41, have been released from the latch rod, D11.

While the drawings show two arms, F3, with hooks, F4, at the rear of the rear door, it is to be understood that one arm, F3, with a hook, F4, placed at`the middle of the rear edge of the rear door would be operative. But by duplicating these arms, F3, and making the engagement with the door at its rear corners, the door can be held with less strain on said arms and the latch rod, D11.

On every side edge of the two doors there is a rising wall, G, which is to lean outward and bear closely against the inner face of the adjacent low-er body side plate, B4, to aid in retaining the material and to reduce outward lateral pressure on the plate, B4. The drawings show the upper edge of the walls, G, having a fold, G1, for stiffening said walls. The drawings show these walls attached by means of an angle bar, G2, having one flange resting on and riveted to the door and having the other flange rising and resting iatwise against and riveted to the walls, G.

For the purpose of this improvement, the axlemay rotate or be held stationary, the wheels turning on the axles. Even if the axles are made to turn in the axle boxes, A3, one or both wheels on each axle may he made loose, as is now done for ears used on tracks having short curves, the purpose being to allow the wheels to roll independently of each other while traversing curves.

By placing the door hinges high and making the distance between the hinges and the opposite edges of the doors short enough, the doors, when released, may turn down into the upright position without going between the track rails. Thus the opening for the doors may be made wider than the space between the track rails, the releasing and the closing of the doors being performed automatically during the travel of the car on the rail track.
