i My invention relates to improvements in materlal-handllng apparatus and is adapted particularly for handling loosem'aterial in piles such as coal and thelike.

More specifically my invention is adapted for loading coal which has been shot down in the mine, it being particularly adaptable for automatically transferring this shot coal from the mine-bottom to the mine car;

F orthe purpose of disclosingmy invention I have illustrated one embodiment thereof in the accompanying drawings in which:

F ig. 1 is a plan view. of the apparatus as a whole; 4

Fig. {l is afront elevation of the same, and v front and rear edges thereof channelmem-' Fig. 5 is an end elevation thereof; 7

In the. embodiment of the invention illustrated ,I provide digging and pickup cylinders 6 which are preferablyfof small diameter andadapted to dig in'under the coal andcause thesame to be movedand to drop on a conveyor 7 This conveyor in turn delivers the coal to a second elevating conveyor 8 which is arranged to deliver the coal to the mine car or wherever desired. apparatus is mounted on a bed frame 9 which forms a skid on which the apparatus is moved and on whichthe driving mechanism of the apparatus isimounted.

The advancing mechanism of the handling apparatus 'comprisesa pair of power-driven drums 10 and ll-which drumsare driven by an electric motor 12 having a worm gear drive connection 13 with the shaft 14, in turn having a worm gear drive connection 15 with the shaft 16. The two drums 10 and 11 are arranged to be connected with the shaft 16 through the medium of operating clutches 17 and 18. These clutches are controlled by operating handles 19 and 20-accessible fromthe operators seat 21 mounted on the base 9. The speed of the motor 12 is controlled by a controller 22 operated by a handle 23 like wiseaccessible from the drivers seat; A cable.

2e is Wound on the drum 10 and after passing over the idler 25 and the pulley 26 the free end thereof,isattachedtoa dead man well Thein advance-of the-loading apparatus. A similar cable 27 is wound on the drum 11 and is attached to a dead man at the rear of the apparatus. By this arrangement the appaawhole may be advanced or retracted in a rightline' direction. By operating one drum and releasingthe other drum entirely the apparatus maybe skewed in either direction.

theapparatus as The bed frame 9 is extended-laterally and on this lateral extension is-mounted at the here 28. Similar members 29 extend between these channels 28 to provide suitable bracing means. This forms a support for the rollers over which the conveyor 7 is adapted to pass and also provides means for supporting the forwardly projecting arms 30 which are arranged at suitable intervals at the front edge of the bed frame andprovide bearing supportsfor the digging and pickup cylinder shaft 31. I r

. ihe digging and pickup cylinder preferae bly comprises a plurality of sections,,each

of which has a hub portion 32 keyed onwthe shaft 31 and a plurality ofradial arms 33,' which arms are adapted toreceive cutter bits'.34:held,.in position by set-screws 35.

These bits .34.co1nprise digging or cutting fingers and are sufficiently sharpened for this tion in the direction of rotation of the pick up cylinder as indicated in Figure 5, the-direction of rotation of the cylinder being in.- dicated by the arrow.

The shaft 31 has a bevel gear connection 36 purpose. They also have a generalinclinalwith 'a'transverse'shaft 37' likewise having a bevel gear connection 38 with a longitudinal spud shaft '39. lYIounted on thebase 9 is a large horizontally disposed bevel .wheel Ohaving a bevel gear'connection 41 with a shaft l2fioperated 'from'th-e shaft 14 through flthe clutch mechanism 43. This clutch mechanism is controlled by an operating lever 44 accessible from the drivers seat. The bevel gear etO comprises a main driving gear for the conveyors and the pickup cylinders; The shaft 39 has a bevel gear connection 45 with this bevel gear 4:0 whereby the pickup cylinders are operated therefrom and the chain drives 46 and d7 for the sections of the convcyor 8 are operated from a shaft 48 having a bevel gear connection 49 with this bevel gear 40. The conveyor 7 is operated by a chain drive 50 taking its power from the shaft 37 so that the various conveyor sections as well as the pickup cylinders are driven in unison when the power is applied to the main drive bevel gear 40. Any form of conveyor desirabie may be used. I have illustrated typically a conveyor comprising sprocket chains 51 arranged to pass over end sprockets and having arranged between them conveyor cross members or vanes 53 which as they are advanced will engage the material dropped on the platform 54 of the conveyor and move the material along. The upper :dges of members 53 are approximately on level with the upper sides of the pick-up cylinders G, the shaft 31 of which lies in a horizontal plane between the lower runs of the conveyor 7 as best seen in Fig. 5 and the vanes .53 are equally spaced, thereby providing a :-:eries of receiving and conveying compart ments for the material delivery by the cylln- 'ders. At the edge of the conveyor opposite the diggingrand pickup cylinders there is provided an inclined back wall 55 extend-V ing well above the level of the cylinders which prevents the material from falling 0d the conveyor 7 Similar side walls 56 and 57 are provided at the side of the conveyor 8 :o confine the material in the path of the conveyor.

In operation the digging pickup cylinders 6 are advanced toward the pile of loose coal, the cylinders being arranged close to the ground and as the cylinders rotate the bits 34 cut into the mass of the coal, causing the pickup cylinders to dig in under the coal whereby the coal will be caused to fall on the conveyor 7 both by this digging in of the cylinder and also the tendency of the bits to throw the coal rearwardly and on the conveyor as they are advanced. The coal is transferred by the conveyors 7 and 8 to the mine car or to any place desired.

I have described the apparatus as being particularly applicable for the handling of coal and in the claims have described it as a coal handling apparatus. It will be understood however that this is typical of the material to be handled and that the apparatus is equally applicable to handling other loose material having the same characteristics of coal, such for instance as gravel, dirt and the like. I

WVhile I have in this application specifical ly described one embodiment which the invention may assume in practice, it will. be understood that this embodiment of the same is shown for purposes of illustration and the invention may be modified and embodied in various other forms without departing from its spirit or the scope of theuappen'dedl claims.
