JACOB M. LONDON, OF TUNNELTON, PENNSYLVANIA, ASSIGNOR, BY DIRECT AND MESNE ASSIGNMENTS, OF ONEFOURTH TO GEORGE M. CRAWFORD AND ONE-HALF TO EMIL M. REFIOR, BOTH OF vITTSBURGH, PENNSYLVANIA. l

vTo all whom t may concern:

Be it known that I, JACOB M. LONDON, a citizen of the United States, residing at Tunnelton, in the county of Indiana and State of Pennsylvania, have invented certain new and useful Improvements in Coal A object of the invention is the-novel manner of mounting t'he cutting mechanism for movement so that a cut may be made of a width equal to the width of the mineand of any depth necessary. f

Another object of the invention is the use of means for supporting the cutters at dif- I ferent heights so as to accommodate varying width of the vein of coal.

Besides the above my invention is distinguishedv in the construction of the mount'- ing for the cutters so that the cutters ma)Y be quickly adjusted to a plurality of different positions and vibration thereof prevented. y

lVith these and other objects in view the invention will be 'better understood from the following detailed description taken in-connection with the accompanying drawings wherein v v Figure l is a side elevation of the machine. Fig. 2 is a top plan view thereof.

Fig. 3 is a rear elevation of the machine.

Fig. 4 is an enlarged sectional view through the coal conveying mechanism.

mechanism for the necessary movements, the latter having a turn table connection D with a truck E movable on suitably arranged rails F in the mine.

The coal cutting mechanism consists of a f platform 1, mounted for rocking movement upon the frame by means of a saddle 2, that forms a` connection between the platform and the frame (l.M In-this particular instance the saddle as shown in Figs. 5 and 6 consists of arcuate shaped ribs 3 carried by the frame and platform and having interlocking engagement with each other as indicated at From this arrangement it will be seen that with very Vlittle exertion the platform may be rocked to a position whereby the upper surface o f the platform maybe arranged at an angle extending in any direction.

After the platform has been moved to the proper position it is held in this position by bolts 5 that have a swinging connection with the frame' l andclamp to the platform by tightening the nuts thereof.

Mounted within the platform is a guide (3 with which cooperates the roller 7 on a guide pin 8 that is 1n turnrigidlv connected to the coal cutting carriage 9. The purpose of this latter construction is to form a pivotal as well as a slidable connection between the carriageQ and the platform, for a purpose hereinafter described.

Also mounted within the platform 1, is' a toothed track 10 of a configuration identical with that of the cut that is made by the coal cutting mechanism and at this point I wish to call attention to the fact that this track 10 may be of any other suitable outline depending entirely upon the shape of the cut to be made.

A gear 11 that has a slidable connection with the cutter drive mechanism to be described later engages the trackv 10 and is held against dislocation therefrom by a of the gear 11. From this arrangement it will be seen that the movement of the carriage 9 along the platform 1, is confined to thel Outline of the cut made by the cutting mechanism and in such a manner that thev number of parts ynecessary is reduced and .wear minimized.

.'The carriage 9 consists of an upper part or section 13 and a lower section V14 that slides upon the platform l. vThese parts are connected and mounted for adjustment relative to each other by means of the screws 15, shown in this particular instance as four in number, one at each corner. of the carriage .and each having screw threaded engagement with one part and non-threaded engagement with the other part.

At this point I wish to call attention to the fact thatalthough screws 15 are shown because of the power that can be accomplished thereby other suitable devices may be used for separating the parts for giving adjustments to the cutting mechanism now to be described. v

This cutting mechanism consists of a ba 16 extending horizontally from the carnage withone end rigidly connected to the section 13. Mounted within the fixed end of the bar is a sprocket wheel 17 cooperating with the sprocket wheel 18at the free end of the bar for giving 'the proper movement to the chain 19 to'wliich, is secured at suitably spaced intervals the cutters 20.

Mounted Within the carriage is an electric motor 21 having drive connection 22 with the sprocket 17 and this drive mechanism may includea clutch 23 for reasons Well known. This'drive mechanism includes a .pair oli gears 24 and 25 coperating with a gear 26 slidably mounted on the shaft of' thegear 11 whereby the latter may be driven at two di'erent speeds for a purposehereinafter described.,

To complete the coal cutting mechanism I connect the screws 15 in pairs by means' Y of chains 28 passing over .sheave 'wheels 27 one of .which is fxedly mountedon each of' the screws 15. If found necessary in practice this shaft may be formed in sections connected together by friction clutches as illustrated. at 32 for obvious reasons. l

From the foregoing description it will, be seen that by constructing and associating the parts as described the coal cutters 20 and .bar 16 may be arranged at a multiplicity of angles and elevations; that is to say by adjusting the parts 13 and 14 relative to each other for raising and lowering 'the cutting mechanism or rocking the platform, 1, upon the saddle 2, and rigidly securing the same in'veither ci its tour inclined positions by bolts 5, y

A very important feature oit my coal cutting apparatus is'that one source of power -is capable otxsimultaneously feeding the carriage in the proper direction and `operating the cutting mechanism and in such a manner thatthecvutting apparatus may be quickly .removed from -the y,iframe C by simply removing vthe pin 8' and raising the cuttingapparatus as a unitvertically. The

advantage of driving the gear 11 at two speedsisnow obviens as during the cutting remota feed the same to the rear of: the machine.

This apparatus consists of a carriage 33 including a bearing 34 pivotally connected to a block 35 slidably mounted upon the frame 1 and automatically moved 'in a manner to be described later.

Fixed to the carriage 33 is an electric motor or othersuitable prime mover 36, the armature shaft 37 of which' has one end associated with a `pair of Worms 33 and 39 .the former driving the conveying means to be described later, and the latter cooperating with a gear 40 lixed upon a shaft 41 that also has .fixed thereon sheave wheels 42 and 43 around which pass chains 44 directed around idlers 45 and connected-to the block 35. From this arrangement it will be yseen that when the clutch 46 arranged on the shaft 41 is operated, movement will be transmitted through the chains 44 toI the block 35 andas a'result the carriage 33`and the conveying means now to be described thereon will be moved toward and away from the pile of coal depending entirely upon the direction of rotation of the-motor.'v

Theremainingend of the armature shaft has a gear connection 47 with a pair of parallel shafts 48 and 49 .each supportingl a bevel gear 50. Associated with each of the beveled gears 50 is a coal'feeder 51 consisting of an upper rake device 52 and a lower rake device 53,the upper havingthe larger capacity. lEach rake device consists of a plurality of teeth or Scrapers 54 lcarried on an endless belt or chain 55 driven in any suitable manner by Ithe shaft56 that receives its motion through a beveled gear 5f? rigidly secured thereto vand engaging the beveled( .gear 50.'.

i The frame 58 of each of the feeders is priivided with a bearing 59 supported for rotation upon one of the heretofore mentioned parallel 'shafts sofas to swing vertically in the arc of a circle as shown in dotted lines in ligg9. For the purpose of swinging the l feeders to this dotted position, a cable 60 is provided lor each feeder having one end connected directlyl to the feeder and trained around suitable idlers 62 and then passed around a drum 63 thatl hasa clutch connec` tion with the .shaft 4l; thus-it will be vseen that the machine may be readilymoved into and out of a mineand quickly arranged |in 'an operative position. c

4 At this point llwish'to'call/attention to iro the vfact that by the use of this swinging connection of the feeders, the cable 60, and the lpivotal connection lbetween thecarriage 33 and the frame l, the feeders' may be 'arranged in a plurality of positions so asto insure the proper coperating ofthe feeders and the lowermost particles of a dislodged pile of coal. a

.This 'manner of acting upon the pile of coal b*T the feeders causes the major portion of the pile vof coal to fall by gravity 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 to gravitate' upon the conveying means now tofbe described.

Arranged directly over the feeders is a shield 64 for preventing the falling -coal from interfering with the operation ofthe feeders. Working directly under4 the' feeders is a scoop 65 that is carried by the frontend of a series of conveyers, two of which, 66 and `67 are pivotally supported atfS'upon 'the carriage 33. The remaining conveyers 68a, 69, and 70 are pivotally connected to' each other as indicated at 7l andfmounted upon a.v second truck 72 also traveling on the rails F. This truck 72 is connected to E by the chain 73 and the conveyersSa, 69 and 70 may be associated with or removed from the conveving means carried bv the carriage33. l l

The conveyers of this'portable conveying l apparatus are adapted to be operated by an electric motor 74 while an adjusting device 75 is provided to raise and lower the conveyer for regulating the feed of coal therefrom into a coal car in the rear. The

conveyers 66 and 67 have a drive lconnection 76 with the worm 38.

If found advantageous in practice the turn table D may be mechanically operated by a worm shaft 77 that engages the rack bar 7 8' secured to one of the disks of the turn table, and -this worm shaft 77 is' driven in any suitable manner as shown diagrammatically at 79. 'v

To complete the invention I arrange at suitable points jacks 80 pivotally connected to the frame and adjustably engaging the wall of the mine.

It isV to be understood that while all of the several features of my improved coal cutting and loading apparatus have special' coperation with one another and 'together constitute a particularly effective machine for-the purpose in view certain of these features may be 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 is further to be understood that the structural embodiment of the invention as awhole and its various features as shown is merely illustrative and not Vrestrictive since I am well aware that many of the detailsof construction can be widely varied without departing from the spirit 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.
