EXCAVATING AND LOADING APPARATUS.
Original application filed July 25, 1917,
To all whom it may concern:
Be itknown that I, JAooB M. LONDON, a citizen of the United States, and resident of Tunnelton, in the county of Indiana and State of Pennsylvania, have invented a new and useful Improvement in Excavating and Loading Apparatus; and I do hereby declare the following to be a full, clear, and exact description thereof.
This invention relates to excavating and loading apparatus and more particularly to that type used in mines for removing dislodged coal and has for its primary object the arrangement of the parts in such a manner that gravity may be relied on to cause the greatest bulk of the material to fall in a position to be readily conveyed to the rear of themachine.
Another object of the invention 1s to provide continuous operating feeders for moving the material to a point where it w1l1 be gathered by a system of conveyers, relylng on independent drive means for movln the feeders into ooal.
A further object of the invention is the manner of mounting the feeders and 'drive mechanism therefor 50 that the feeders may be arranged at difi'erent angles with rela tion to the pile of coal.
Beside the above my invention. is distin-[ guished in the manner of driving and su porting the feeders so that the same may e quickly thrown to an operative or an moperative position and when in the latter position the feeders will not interfere with the following the travel of the apparatus into and about the mine.
With these and other objects in view the ..Specification of Letters Patent.

Patented Jan. 6, 1920.
Serial No. 182,658. Divided and this application filed March 7, .1918. Serial No. 220,925.
Figs. 6 and 7 are detail views of the saddle arrangement connecting the device to the coal cutter.
Fig. 8 is a front elevation showing in dot and dash lines an inoperative position of the feeders.
Figs. 9 and 10 are detail views of the turn} table. V
Fig. 11 is a detailed sectional view of the drive mechanism for the feeders. v y improved form of coal loading apparatus is connected to a frame C at a point directly below the coal cutting mechanism fA which may be constructed as illustrated in my copending application, Serial No. 182,658; filed July 25, 1917, of which this application is a division, but it will be understood that the subject matter of thi application is not limited to use with the device described in my co-pending application, but maybe used with other machines if desired. A y
The frame C is mounted upon a suitable form of wheel supported turn table B in such a manner that when acting in combination with other mechanism, hereinafter described, a pile of coal may be acted upon at various angles and the same moved toward the rear of the apparatus.
A carriage 1 including a bearing 2, pivotally connected to M01001: 3 slidably mount- .ed upon the frame 0, is automatically moved in a manner now to be described. Fixed to the carriage 1 is an electric motor or other suitable power device 4:, the armature shaft 5 of which has one end as sociated with a pair of worms 6 and 7, the former driving the conveying, means to be described later, and the latter c 6 erating with the gear 8 fixed upon the sha 9 that has also fixed thereon sheave wheels 10"and 11 around which pass chains-'12 directed around idlcrs 13 an'd'connected to the block 3. From this arrangement it will be seen that when the clutch 14c, arran ed in the shaft 9, is operated, movement wi lbe transmitted through the chains 12 to the block 3 and as a result the carriage l and the convey'mg means, to be described later, will be toward or away from the pile of coal The remaining end of the armature shaft 5 has a gear connection 15 with a pair of parallel shafts 16 and 17 each supporting a eveled gear 18. Associated with each of the beveled gears 18 is a coal feeder 19 consisting of an upper rake device 20 and a lower rake device 21 of different capacities, the upper having the larger capacity. Each rake device consists of a plurality of teeth or scrapers 22 carried on an endless belt or chain 23 driven in any suitable manner by the shaft 24 that receives its motion through a beveled gear 25 rigidly secured thereto and engaging the beveled gear 18.
The frame 26 of each of the feeders is provided with a bearing 27 supported for rotation upon one of the heretofore mentioned parallel shafts so as to swing vertically in an arc of a circle, as shown in dot and dash lines in Fig. 8. For the purpose of swinging the feeders to this position a cable 28 is provided for each feeder having one end connected directly to the feeders and trained around suitable idlers 29 and then passed over a drum 30 that has a clutch connection with the shaft 9; thus it will be seen that the machine may be readily moved into and about in a mine and quickly arranged in an operative position.
At this point I wish to call attention to the fact that by use of this swinging connection of the feeders by the cable 28, the wheel supported turn table .B, and the pivoted connection between the carriage 1 and the frame C, the feeders may be arranged in a plurality of positions so as to insure the proper cooperation of the feeders with the dislodged pile of coal.
This manner of acting upon a pile of coal by the feeders causes the major portion of. the coal to fall as the feeders only excavate a certain amount of coal from under the pile of coal and gravity is relied on for the major portion of the pile togravitate vupon the conveying means hereinafter described.
Arranged directly over the feeders are shields 31 for preventing the falling of the coal from interfering with the drive mechanism of the feeders. Working directly under the feeders is a scoop 32 that is carried by the front end of the conveyer 33 and at this point I wish to call attention to the fact that the operation of the feeders and the location of the shields and of the scoop are such that the coal will be 'brought and fall between the two sets of feeders and be caught by the conveyer 33 which has its end located at this point. p
Conveyers 33 and 34 are pivotally supported at 35 u on the carriage 1 and are adapted to'receive and convey the dislodged coal-tojthe rear'ofxthe machine The con veyers 33 and .34 have a drive connection 36 With the worm 6; Forthe purpose of illustration I have shown a system of con veyers JD, mounted one truck 42 and arranged in the rear of the conveyer 34 for continuing the travel of the material. .The truck 42 is connected to the truck 43 by any suitable means as chain 44.
If found advantageous in practice .the turn table .]3 may be mechanically operated by the worm shaft 37 that en ages the rack bar 38 secured to one of the dis s of the turn table, and this worm shaft 37 is driven in any suitable manner as shown diagrammatically at 39, in Fig. 1 of the drawings.
To facilitate the travel of device about a minev thetruck 43 may be provided with a motor 45 suitably geared thereto. Motor shaft 46 carries the sprocket 47 for driving the worm shaft 37 by means of the chain 48 operatingthe sprocket 49 which has a clutch connection 50 with the worm shaft 37. a
In Figs. 6 and 7 there is shown the saddle arrangement 51 which connects the frame C to the coal cutter A. This arrangement permits the rocking adjustment of the 7 coal cutter upon the frame CL Bolts 40 Y are provided for securing the coal cutter in cooperation with one another andtogether' constitute a particularly effective machine for the purpose in view, certain of these features maybe applied in other relations and I therefore desire to cover the combinations present in the several parts of my machine whether employed in .the general organization shown or elsewhere.
It isfurther understood that the structural' embodiment of the invention as a whole and its various features as shown are merely illustrative and not restrictive since I am well aware that many of the details of construction can be widely varied without departing from the principle of'the invention. ,I therefore do not desire to be limited in this construction or in any other except as set forth in the appended claims.
I claim-- 1. In a coal loading apparatus, a carriage mounted for vertical and horizontal movements, and coal feeders swingingly connected to the carriage and each including an upper and a lower rake device of different riage mounted for-"vertical and horizontal movements, coal feeders swingingly connected to the carriage, each. including an upper and a lower rake device of difierent capacities, and means for swinging the feeders to an operative or inoperative position.
31in aeoal loading apparatuaa carriage mounted for vertical and horizontal movements, coal feeders swingingly connected to' the carriage, each including an upper and a lower rake device of different capacities, means for swinging the feeders to an operative or inoperative position, and means for changing the active positions of the feeders;
