ERNEST THOMAS KELL, OF BENTON, ILLINOIS.

COMBINED SHOVELING Application filed .Tune 5;

To all whom t may concern.' Y

Be it known that I, ERNEST T. KELL, a citizenrof the United States, and a resident of Benton, in the county of Franklin and' State of Illinois, have invented a new and useful Improvement in Combined Shoveling vand Loading Devices, of 4which the following is a full, clear, and exact description. My invention relates to improvements 1n combined shoveliiig and loading devices, and

it consistsV in the combinations, constructions, and arrangements herein described and claimed. l

An object of my invention is to provide a combined shoveling` and .loading device which will convey the coal, which has alredy been dynamited, to a mine car or the li e. Y

1922. seriai No. 566,096.

a frame 1 on which is 'mounted'a power source 2, and a second power'source 3. The motor 2 is connected by nism 4 anda chain 4C with a4 caterpillar a reversing mecha-v truck 5. From this construction it will be observed that the frame 1 may bemoved vforwardly `o r backwardly Vby merely actuat# rear of the device is supported bywheels 7.

A bucket carrying i roller chains 8 and buckets 9 is disposed in the front of the frame 1 (see Figures 1 and 3). The chains 8 are disposed around sprockets 9 and 10, and pivotally support the buckets 9 therebetween. The sprocket 10 isr secured to a shaft 11 which in turn is driven by a belt connection 12 from the motor 3. As shown in Figure 1, the motor ing a lever 6 so as to operatively engageV the motor 2 with the endless tread 5. rIhe means comprisingv 3 is preferably of the electric type, although it may be of any other type desired. As heretofore stated, the buckets 9 are pivotally carried by the chains 8 by means of trunnions 13 which extend transversely from the buckets 9 at the vertices thereof. The

buckets in reality form triangular-shaped conveyors. As clearly shown in Figure 4c,

- the front edge Vof the bucket 9 is serrated as at 14C so as to more readily scoop up fthe coal which has already been blasted; YThe side 15 of the bucket has laterallygeXtending ears.16 which are adapted to engage with the lugs '1P/these lugsbeing parts of the chain 8. Y

Guide vmembers 18 are carried by the frame 1 and support the buckets and 'chains during a portion of their trip. A second Vpair of guide members 19 are disposed-between the sprockets 9 and 10 andare adapted to support the ears 16 after the buckets have been emptied. It will be notedfro'm Figure .3 that thevbuckets moving toward the end of the frame 1 have their laterally extending projections 2O caught in grooves 21, whereby. the front end of thebucket is f kept do-wn and forcedv into engagement wit-h the pile of coal as the back portion is swung up and around the sprocket 9. As soon as the sprocket 9 starts to carry the bucket 9 toward the guideways 18, theprojections 2O have been pushed forwardly so as to clear the guideways 21, and the lugs 17 have engaged with the ears 16 of the bucket so as to lift the bucket into the position shown in Figure 3 of the drawings. The Weight of the coal which was formerly carried by the ggg side 22 of the bucket is now carried by the side 15, this weight in turn being supported by the guideways 18. A further movement of the bucket carries it over the sprocket 10, the lugs 17 tipping the bucket so as to empty the coal therefrom onto a conveyor belt 23. A shield 2A prevents the coal from entering the compartment which contains the motors 2 and 3. It will also be apparent that the bucket which has just previously been dumped, forms a shield for the coal which is being dumped by the succeeding bucket, thereby preventing the coal from spilling over the end of the conveyor 23. The conveyor 23 carries the coal to any loading point, such as a coal car or a coal pile (not shown). rlhe conveyor 23 forms no part of my invention, except in so far as it cooperates with the parts hereinbefore described. The conveyor is actuated by any means, such as by a motor (not shown). IThe buckets in rounding the sprocket 1() have their vears 16 engaged by the guideways 19 so as to swing the bucket into the desired position. As the bucket moves on, the side 22 engages with the floor 2A of the frame 1, this floor being adapted to guide the projections 2O of the bucket into the gu'ideways 21. 1n case the fioor of the coal pile, which is being carried away by means of the bucket 9, is below the floor 24 of the frame 1, the end o-f the door 211 may be lowered. rlhis construction is clearly shown in Fig. 5 of the drawing.

A plate 25 is pivotally secured at 2,6 to

the frame 1 and is adapted to form a contiguous wall with the floor 24. The frame 25 has upwardly extending lugs 2 7 through which bolts 28 are disposed, these bolts being slidably mounted in slots 29 in the sides of the frame 1. lt is obvious from this construction that the bolts 28 may be loosened so as to permit the plate 25 to drop into the dotted line position shown in Figure 5, whereupon the buckets 9 will scoop the coal from a lower plane.

In case the coal which has been dynamited is not loose enough so as to readily fall into the buckets 9, means for breaking up the coal is actuated. ln fact this means is preferably kept in operation during the operation of the buckets 9. As clearly shown in Fig. 2, the shaft 30 which supports the sprockets 9 also supports sprockets 31. rlhese sprockets are mounted on the inside of the frame 1 and adjacent to the walls of the frame. Sprockets 3A and 35 are carried by the sides of the frame 1 and are substantially in ver tical alinement with respect to each other. A roller chain 36 is mounted on the sprockets 31, 311, anc 35, this roller chain carrying picks 37. The chains 36 are so disposed that the picks 37 will project beyond the end of the frame 1 when the picks are passing between the sprockets 34 and 35. As shown in Figure 2, the picks 37 are removably secured to the chains by means of set screws 38. lf the coal is not filling the buckets 9 to the desired capacity, the frame 1 may be moved towards the piley of coal by means of the engine 2 and the caterpillar trucks 5 so as to cause the picks 37 to gouge into the pile of coal and to break up the pile into smaller pieces, whereupon the coal will readily fill the buckets and be carried away by the conveyor 23.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. As heretofore stated, when it is desired to remove a pile of coa-l which has previously been dynamited, the tractor is moved towards the desired pile by means of the motor 2. As soon as the tractor has reached the pile, the bucket conveying mechanism may be actuated, and the coal breaking mechanism also actuated, whereby the coal from the pile will be carried to the conveyor 23 and from thence to the desired location. The buckets 9 are held in a horizontal position while they are being filled and are also moved toward the pile of coal while they are being filled in the manner herebefore described. lt is obvious that as fast as the buckets carry away the coal which is disposed adjacent to the forward end of the machine, the machine may be moved towards the pile, whereby the buckets will again carry away the coal deposited adjacent to the end of the machine.

The device consists of relatively few parts l and is durable and eficient for the purpose intended.
