MACHINE FOR UNLOADING CARS.

SPECIFICATION forming part of Letters Patent No. 366,033, dated July 5, 1887.

Application filed February 16, 1887. Serial No. 227,795. (No model.)

To aZ Z zuhom it may concern:

Be it known that I, JOHN SOULLY, of South Amboy, in the county of Middlesex and State of New Jersey, have invented a new and Im-,

. load from the ends of the car to the trap (lolated usually in the center of the car) is considerable, andhas hitherto been done entirely by hand. I Y

The object ofmy invention is to do this work by machinery; and to this end my invention consists, principally, of amachine constructed to operate horizontally-movable blades or shovels arranged to be carried back and forth from the ends to the center of the car for shifting the coal or other material with which the car may be loaded to the discharge-opening.

The invention also consists of the combined mechanism of the unloading-machine, whereby the shovels may be raised and lowered and moved to different positions in the car, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, formingapart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my new and improved unloading-machine. Fig. 2 is a front elevation of the same. Fig. 3 is a side elevation, showing a portion of a car to be unloaded. Fig. 4 is a sectional elevation taken on the line 00 w of Fig. 1, and-Fig. 5 is adetailed sectional plan view on the line y y of Fig. 3.

A B C represent three strong uprights rising from the base D.

In suitable bearings secured to the upper ends of the uprights A B is the power-shaft E, to which motion is imparted by any suitable motor, and this shaft is geared by the beveled gear-wheel F to the beveled gear H, which is secured to the sleeve I, (see Fig. 1,) placed loosely upon the long horizontal shaft J, and held from endwise movement between the two uprights A O. The horizontal shaft J is connected to the sleeve by a feather, a, so that the said shaft may move freely endwise through the sleeve I, but will always revolve with the said sleeve when the machine is in operation.

K K represent two heavy plates or beams held toopposite sides of the uprights A G by cleats b b, secured to the said uprights,which form Ways, which while they hold the beams firmly in horizontal position at the same time permit them to be moved freely longitudinally for carrying the shovels L to different lateral positions in the car Y. The endwise movement of the beams K is, by preference, accomplished by the shaft M, journaled in the up right 0 and revolved by the hand crank-shaft M and chain and pulleys M M the shaft M being connected to the beams by small pinions c, secured thereon, engaging with racks, (1. formed upon or secured to the lower edges of the beams. The outer ends of the beams K are connected together by the headplate or frame N, constructed to form a horizontal channel, N, (see Fig. 5,) to receive the arms 0 and hold them in horizontal position at right angles to the beams K.

In the center of the channel N is journaled the short vertical shaft 1?, which is revolved by the shaft J by the two beveled gear-wheels P, (see Fig. 2,) and upon the short vertical shaft P, withinthe channel N and between the arms 0, is secured the gear-wheel Q, (see Fig. 5,) which meshes with the racks f f, formed or secured to the adjacent surfaces of the arms 0, so that the revolution of the shaft P and gear'wheel Q will move the arms 0 simultaneously in opposite directions .for earlying the shovels Lto and from each other. The end of the shaft J to which the beveled gear P is secured is held in the bearing J, attached to the head-block or frame N, so that the longitudinal movement of the beams K moves the shaft J longitudinally and always keeps the gear-wheels I P in gear with each other. The shovels L are heavy plates of metal, equal in length to about one-third the width of a common railway coal-car, and are attached to the outer ends of the arms 0 by the heavy upright bars It, held loosely in passages s,

formed in the plates S S at the outer ends of v the arms 0, as shown clearly in Fig. 2, sothat the shovels may be raised and lowered by means of the ropes T and Windlass T, or other- IOO wise, for lifting them from the bottom of the carand dropping them into the load. The said Windlass T is located upon the base D, and the ropes T pass from the Windlass-drum up over the pulley g 9', attached to the beams K, thence around the pulleys g g, journaled upon the head block or frame N, thence over the pulleys g journaled between the plates S S at the outerends of the arms 0, and thence down the bars R, to which they are attached at or near the shovels. The Windlass is revolved from the main power-shaft E by the belt U passing over the pulley on the shaft V, which is connected to the shaft of the windlass-drum by the two gear-wheels V V The gear-wheel V maybe moved upon the shaft V by the lever V for throwing the Windlass in and out of gear, and when thrown out of gear the Windlass may be held from revolving by a brake, W, so that the descent of the shovels may be under the instant control of the operator.

In operation, the shovels being elevated to the position shown in dotted lines and the beams K and shov'els drawn toward the upright A as far as required, and a loaded car in position, the crank M will be revolved to move beams K and shovels L out over theoar. Then the lever V will be moved to ungear the Windlass T the operator in the meantime pressing the brake to hold the windlass from revolving. The shovels being now in position over the car, the operator will release the brake, whereupon the shovels will drop of their own weight down into the load in the car and at the ends of the car. The powershaft E will now be put in motion in the proper direction, which will revolve shafts J and P, which will move the arms 0 longitudinallyin opposite directions and draw the shovels toward each other to the center of the car, moving a large portion of the load with them to the discharge-trap. WVhen the shovels have thus reached the center of the car, the Windlass will be put in gear and the shovels elevated by winding up the ropes T. Then the main shaft E will be reversed in its revo- ]ution,which will reverse the shafts J Pand move the arms 0 and shovels L outward to the ends of the car. At this time the crank M will, be revolved to move the beams K a short distance farther outward toward the longitudinal center of the car, and then the Windlass will be again released to permit the shovels to drop, and then they will be drawn toward the discharge-opening, as before, and this operation will be repeated until the car is unloaded.

Instead of forming the shovels L of solid plates of iron, they may be made with tines or forks, as shown in dotted lines in Fig. 3.

Having thus fully described my invention, I claim as new and desire vto secure by Letters Patent 7 .1. A machine for unloading cars, constructed substantially as herein shown and described, and comprising main supporting-beams K, holding-arms O, in combination with shovels L and bars R, held at the ends of the arms, and means, substantially as described, for moving the arms longitudinally for moving the shovels back and forth, substantially as and for the purposes set forth.

2. The beams K, carrying the horizontal arms 0 at the outer ends, and the arms Oand the shovel-bars R, in combination with means, substantially as described, for moving the arms 0 horizontally, and means for moving the shovel-bars Vertically, substantially as de'- scribed.

3. The beams K, carrying arms 0 at the outer ends, and the arms 0- and the shovelbars It, in combination with means, substantially as described, for moving the beams longitudinally, means for moving the arms 0 longitudinally at right angles to the beams K, and means, substantially as described, for moving the shovel-bars Rvertically, as and for the purposes set forth. i

4. The beams K, provided at their outer ends with the hollow frame N, the shaft P, journaled in said hollow frame, and the gearwheels P Q, in combination with the arms 0, carrying the shovel-bars and provided with racks, and the shaft J, geared to the shaft P, substantially as described.

5. The beams K, held in ways at the sides of the main uprights, and the shaft J, connected at its outer end to the beams K, in combination with means for moving the beams and shaft J longitudinally and means for revolving the said shaft, substantially as described.

6. The shovel-bars R, held in passages at the ends of the sliding arms 0, in combination with thewindlass T and the ropes T, passed from the Windlass over suitable pulleys and attached to the arms R, for raising the same, substantially as described.

7. The beams K, held in ways at the sides of the uprights and provided with racks, in combination with the shaft M and crankshaft M, connected to the shaft M, and pinion a, secured upon the shaft M,'to engage with the racks on the beams for moving them longi tudinally, substantially as described. 7

8. The shaft J, journaled at its outer end in a bearing attached to the head-frame N of the beams K, and passed through the sleeve I, to which it is connected with a feather, in combination with means for revolving the sleeve and means for moving beams K, horizontally, substantially as described.
