MIN ING- APPARATUS.

Applicaton 1ed`Apri1v17, 1916, Serial N'o. 91,565. i Renewed November 22, 1920. Serial No. 425,888.

To a-ZZ w/"zom t may concern Be it known. that I, EDMUND C. MORGAN, a` citizen of the United States, residing in New York, inthe county of New York and State of New Yorlghave invented certain new and useful` Improvements in Mining Apparatus, of which the following is a specification.

Thisv invention. relates .to apparatus for mining coal and similar material, and has for its object the provisionof apparatus of this character which shally be more economical` andv efficient in. construct-ioni and operation. The invention is exemplified in the combination -and arrangement of. parts shown in the accompanying drawings and described. int-,he following specification, and it is more particularly pointed. out in. the appended claims. V

Referring more particularly to the drawings, the numeral 15 designates a vein. of coal tobe minedyl-G andr17v are entries driven through the vein of. coal spaced from.

one another and extendingpthrough the vein any distance whichv may be found desirable or convenient. A pillar ofV coal 15 left between the entries l16 and 17` is removed by a series of cuts taken. across the face ofthe vein transversely to the direction of the entries 16 and 17. The machine'for severing the coal from the pillar is made up\of two sections, the front section 18 being designed to sever the coal from the face of. the vein while the rear section 19; defiects the coal from the position in. which it is left by the section 18, breaks it into pieces and deposits 4it upon a conveyor 20 which extends along the face of the vein being worked, and when it receives the coal from the machine transports it to one of theentries 16 where it is receivedby a second conveyor. section 21, which` in turn carries Ait to a car or. other transporting device by means of which it is still further transferred. to the mine shaft.

The construction of the mining machine proper will best be understood by. reference to. Figs.. 3 to 9 inclusive. The forwardV or severing section 18 of the machine, is provided with abase 22 arranged to be drawn along the lioor ofa mine chamber. Extending upwardly from` the base plate 22 isa guard wall or plate 23 which is curved, horizontally, and partially encloses the oper.- ating mechanism. for the cutting apparatus. The forward. edge of the plate` 23,. as shown in Figs. 3V and'y 7, is provided with a thickened upright portion 24 having guideways 25 at one. side thereof. A bar l 26 is arranged to slide vertically inA theyguideways 25 and' is held` in place by a platef27. secured, to,the member 24by cap screws 28.. The bar 2G.has a. pair ofl lugs 29 and k30 secured thereto and projecting above and below the ends off the member 24 respectively. The lugs 29. and 30 are provided with screws 31 andf32by means ofwhicli Ithe bar 26,1nay be adjusted. vertically relative to the upright memberl 24. The upper and` lower ends of the bar 2G are-pro- -vided with curved guides 33 and 34 respectively, about which a cutter chain 35 is directed. 4Horizontal arms 36 and 37 extend from the upperandflower ends of the bar 26 respectively and are provided at their. forward edges with guideways for the chain 35. The bars 36 and 37 are curved at their outer ends and unite with a vertical cutter bar 38 which connects the outer ends of the horizontal liars and forms a continuation of the front edge of the inclined ibase plate 77 is a scoop or scraper 80 arranged to pick up any-.lose particles of material which may be lying on the floor of the mine in the path of movementof the inclined section 77. The

defiect'or or coal plow section 19 is connected'with tlie :cutter 18 by the cable 71 which is secured to the section 19 at 81, as shown in Fig. '3. j

The backward and vinward curvature of the portion 82 (Fig. 3) ofthe deii-ector plate 76, permits the top portion of the severed section 70 of the material being mined, to tip backwardly as the lower portion of the Asect-ion is moved outwardly by the deflector plate. In thisway the detached portions of the core section of material are gradually tipped over on their sides as they are `moved away from the face of the vein onto the conveyor 20. l

The construction of the conveyor will best be understood'from Figs. 1, 2, 10, 11 and 12. As shown in Figs. 1 and l2, the section 20 of the conveyor is positioned along the face of a mine vein and is spaced a suflicient distance from the vein to permit the cutter section 18 of the mining machine to move between the vein and the conveyor with 'the cutter frame extending into the face of the vein to form a kerf for severing the material from the vein. The cutter section is guided along the conveyor frame on the guide fiange 79`which` cooperates with an overhanging flange 83 (FigfG) which is secured to the router edge of the' base plate 22 of the cutter section 18 and corresponds t0 the flange 78 'on the de'iie'ctor or plow section 19. The'conveyorA properis made upl of a bed plate 85 (Fig.12) on whichthe lower run 86 of an endless belt conveyor is arranged to travel. The upper run 87 of the conveyor is guided by flanges 88 projecting inwardly from the walls of the conveyor bed plate 85. The forward end of the conveyor is provided with an upwardly inclined section 90 and a base plate 91 which extends beneath the upwardlv inclined portion 90 is secured tothe base plate 85 at the point where the section 90 begins its upward inclination. Mounted on the base plate 85 adjacent the forward end of the inclined `section 90, is the section 21 of the conveyor which receives the material from the section 20 and discharges it into a car or other transporting device. The section 21 is carried by a circular track 92 spaced upwardly from'the base plate 91 and secured to the base plate by lag screws 93. The bed plate 941- of the conveyorv section 21 has a plurality of downwardly projecting supporting posts 95 connected toits lower surface.V The posts 95 are provided with notches 96 which cooper; ate with the track section 92 andysupport the conveyor section 21 in a manner to permit rotation ofthe section 21 in a horizontal direction to-provide for adjusting the position of the forward 'end of the'section 21. This will permit the section 21 to discharge onto cars on either one of a pair of tracks that may be placed in the entry 16.

The conveyors aredriven by a motor 97 mounted on the plate 91 and geared to drive a pair of shafts 98 and 99 journalled in pedestals 100V secured to the plate 91. The shaft 98 carries a drum 101 which may be clutched thereto by a clutch 102. The shaft 99 carries a pair of drums 103 and 104 which may be clutched to this shaft by clutches 105 and 106 respectively. The end of the shaft 98 opposite the drum 101 carries a bevelled pinion 107 which meshes with an idler gear 108 mounted to rotate on a pedestal 109 projecting upwardly from the plate 91. The idler 108 meshes with a. pinion 110 secured to a shaft 111 rotatably mounted in bearings 112 carried on the under face of the bed plate 94. The shaft 111 carries a sprocket wheel 113 at its outer end which drives a chain 114 meshing with a sprocket wheel 115 on a shaft 116 arranged to drive the endless belt 117 of the conveyor section 21. Be-

cause of the idler' gear 108, it is clear that the conveyor belt 117 may be driven through the mechanism described regardless of the angular position of the conveyor section 21 relative to the conveyor section 20.

The drum 101 has a cable 118 arranged to be wound thereon which is guided around i pulleys 119 and 120 into the entry 16 where it is carried forwardly along` the entry to any desired' position and-has its end iixedly secured in any suitable manner. The drum 103 carries a cable'121 which passes. around pulleys 122 and 123 to a position in the entry 17 corresponding to the position of the cable 118 in the entry 16.' It will be apparent that when the cables 118 and 121 are wound on their respective drums the conveyor will be drawn inwardly toward the face of the mine vein. The position of the conveyor is thus adjusted after each cut made by the mining machine. It will be seen that the direction pulleys 120 and 123 are each provided with a pair of oppositely disposed guide pulleys so that` the cables 118 and 121 may be guided in either direction from the ends of the conveyor, thus making it possible to move the conveyor in either direction in the mine chamber.

The drum 104- is provided with a cable 125 which passes over a pair of guide pulleys 126 at the lefthand end of the conveyor section 20, as viewed in Figs. 1 and 10, and thence backwardly past the deflector section 19 to the cutter section 18 where the end of the cable is secured to the cutter section. Then the cable 125 wound on the drum 104; the cutter section 18 will be drawn backwardly until it engages the deliector section 19, aft-cr which both sections will' be drawn Yio baekwardly together until they reach a position adjacentV the end of the conveyor section 20. After Vthey have been brought tov this position, the conveyor may be moved by the cables 118 and 121, to a new cutting position, the conveyor section 2O carrying with lit the mining machine and also the discharge section 21 of the conveyor. It should be Vnoted that during this movement of thel conveyor into position for a new cut, the seci tionsV 18 and 19 of the mining machine are ginning its cnt. If the parts of the machine were rigidly secured relative to one another,V

with Vthe detlector plateV 72 sutliciently removed Yfrom the cutter topermit the plate to easily transfer `the severedmaterial after it has broken from its forward end by gravity,

' l.or to provide sutiicientfleverage for the plate itself to break comparatively hard material from the mine wall, a. Y much wider entry would Vbe necessary to Ypermit the machine to be moved into position to start a cut than is required bythe piesent construction.

Since the severed material is deflectedonto the conveyor by the forward movement of the machine, it is apparent that some of the material will be left in the position in which it is first placed when severed from the mine vein at the time when thefmachine has completed its movement across the face of the vein and finished the disconnection of a section. In order to care for this residual material, an abutment 130 is secured to the base member 91 'ofthe conveyor and is rigidly held in position in alinement with the section of material being severed and at the end of the path of movement of the loop core cutter. Y The abutment 130 is made of proper size to pass through the loop formed by the cutter chain and vwhen the machine reaches the end of a cut its forward movement is Ycontinued a suflicient amount to force the material through the loop and ontothe base plate 75of the deflector section 19.' If it is found necessary, the drum 61 may be rotated Vto draw the deflectoi section 19 toward the cutter section j18 in order Vto bring all of the severed material onto'the plate 75. When this has been done, the Amachine may be Vmoved backwardlyto its initial position and willfcar'ry with it the severed material that has not been discharged ontothe conveyor A ABy the mechanism .as coal, founduinV approximatelyV horizontal V20.` This .material will be forced from the vdeflectorV section as soon as the next cut has been started.V

described, material vsuch veins or layers, may be mined with a minimum degree of expense and danger. The entries` 16 and 17 may be made very narrow so that they will require no timbering. The v Vthe conveyor section 2t) moves forwardly, the

roof of the mine being allowed to fall in the rear of the operation. In this way all of the coal is removed and no tiinbering is left in the mine, and the operation is carried on rapidly and at a minimum expense.
