Application med November 3, 1910, Serial No. 590,445.

To all whom t may concern Be it known that'L EDMUND C. MoRcAN. a citizen of the United States, residing at Morgan Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Mining-Machines, of which the folio ingr is a specification.

This invention relates to mining machines particularly adapted, though not necessarily limited in its use, for what is known as lon Wall Work, and one of thix object o f the invention is to provide an endless vut ting :apparatus for cutting thc coal and which cutting apparatus also forms a conveyer for conveying away the detached pieces of coal to be discharged from thc machine at a convenient point.

A further object is to provide an improved mining machine of this character in which there is employed an endless cutting apparatus embodying .detachable bits or tools and which apparatus encompasses the driving mechanism so that the bits or tools may be readily ren'iovcd and rcplared from thc rear of the machine, thereby permitting the construction of a compact machine of thisl character.

A further object is to provide an improved machine of this character which will protrude ver \Y little outside of the path ol' the cutting. so thnjt the tracks for the cars will he arranged in close profiimit)I to the .face of the coal and inside of thi` props and so thatl the tracks may be readily niowd over `toward the face or wall of the coal as the cutting or mining progresses.

A further object is to provide improved means for supporting and guiding the cut tcr chains from the lower or under side thereof thereby leaving the upper side 'rec` to form ay conveyer for the mined or de ta'clied pieces of coal.

further 4object is to provide an improved endlcss `cutter comprising pivotally connected links and cutting toolsV secured thereto, the cutting `edge of'which tools is arramgcd substantially on aline with the joint or pivot of the cutting links in the rear of the tool, `thereby overcoming the tendency of the tools to gougel A further Objectis to provide an improved machine of this character which will be simple, durable and cheap m constructiona'nd effective and efficient in `eration. To the attainment of these ends and the shaft which meshes 4turn meshes with a Worin' gear 17.

accomplishn'irnt of other new and useful objects as will appear, the invention consists in the features of novelty in the construe-- tion, combination and several matters'hercinafter more fully described end claimed and shown in thc accompanying drawings illustrating an embodiment of the Figure l is a proved machine of this character consti-nrt ed in accordance with thc principles ol' llos invention.

Referring more particularly to thc draw ings and in the present exemplitic-.ition nl' thc in vcntion. the numeral 10 designates the main supporting frame., the hase of which is adapted to slide along the lioor of a drift or galli-rv. and mounted upon the frame l() is a motor 11 by means of which the machine may he advanced. This motor 11 is provided with a shaft 12 mounted in suitable journals and E gear 13 is secured to the with a companion gear .l-l on an uprightshaft 15.'\\hich latter is rotatahlvv mounted in suitable. journalsf A worm wheel 16 is secured to rotation therewith and this Worm wheel in Th(l worm gear 17 is secured to a shaft 18 for ro tation therewith, (see particularly- Figs. l and 4) and the .haft is journaled in suitahle bearings 19. Mounted upon the main frame l0 is a su port 2O which is prefer-ably elevated some distance above the base of tlu m'ain frame and is provided in each oi' its outer faces with a groove 2l, in which grooves are mounted Slides, one of the slides bein supportV nchor arms 23 are pivotally coninvention, and in which-- top plafn view of an im f1 the shaft 1.3 for.

arrangement of the f* online ti 45,

u mounted on euch side of the nected by -By alternately a `in this manner it will be apparenttbat when one extremity to one of the slides 22 on one side of the supp/ort 2O and snmlar anchor arms 2l are pivotally connected by one extremity to the other of the slides 22 and one pair of these anchor arms 1s preferably arranged in advance of 'the other. The arms are of such a lengththat their `free extremities will engage the roof and the {ioor of the ldrift or allery and are of a combined length sligh ly greater than the height of the drift or gallery. Each of the arms 23 is provided with a proJecting ear or lug 25 which lattern-are connected by means of a bolt 26 passin loosely therethrough and an elastic mem er 27 such as a coil spring or the like, is' arranged between the ears or lugs 25 ai'id tend normally to separate the latter so as to force the respective extremities .of the anchor arms 23 into en agement with the floor and roof of the drift or gallery. A similar connection is provided between the arms 24. These pairs of anchor arms are arranged at the rear of the machine and are adapted to advance the machine and for this 'urpose the slides y22 are each connected wit4 a crank arm 28 on the shaft 18, as shown more clearly in Figs. 1 and 4, so that when the shaft 18 is rotated in the manner already set forth the crank arms 28 will alternately move `the slides 22 in their guideways 21 in the suppf-rt 20 in opposite directions. When'the slides are moved in their guides ina direc# tion away from the machine, thef'point of pivotal connection of the respective pairs of arms will be forced in a direction to cause the arms to grip the floor and roof of the drift or gallery, and when in this position, a further movement of the slide in the same direction will force'the machine forwardly. When' the slides 22 are moved in the guides in a direction toward the machine, the respective pairs of anchor arms will be advanced with respect to the machine so as to secure a new (grip onthe floor and wall.

rancing the pairs of arms one Apair ofarms is being ,adya-nced` the other pair will act to advance the machine. Supported by the base of the machine and rotatably mounted on upright axes 29, 30,- at the forward end of the machine are sprockets 31, 32, which are preferably arranged in line with each other. An idle pulley 33 is rotatably mounted u-pon an upright axis 34y at the rear of the machine and preferably in line with `the axis 30. An upright shaftp is also varranged at the rear o the, machine and in line with the axis 34 of thepulley 33, and a sprocket 36 is secured to the shaftl 35 for rotation therewith.

AV cutter comprising an endless belt 37, preferabl. inthe form of a chain constructedof lin which links are pivotally connected, is provided and this endless iexible member surrounds the'

sprockets

31, 32, 36 and the idler 33. The cutting tools 38 are removably secured to the endless member 37 in any suitable. manner but preferably the endless member is provided with sockets 39, which project beyond the outer side of the endless member and into which sockets one extremity of the tools or cutters project, and the latter are held in position and against accidental displacement in any suitable manner, preferably by means of fastening screws or bolts 40. The endless member 37 encompasses the motor 11 and the operating gears and mechanisms of the cutter as well as the operating mechanism of the remaining portion of the machine so that the cutters ortools 38 may be readily removed from the rear of the machine, thereby enabling the machine to be constructed compactly so that it will operate in the very contracted space in which it is intended to work.

The cutters or tools 38 are arranged at different inclinations so that their cutting edges when in engagement with the wall or the coal to be cut will operate in different horizontal planes, as shown more clearly in Fig. 8, and the cutting edges of the tools are arranged substantially on a line With the joint just in the rear of the tool, and which Joint forms the pointof pivotal connection of the links of the cutting belt, so that all tendency ofthe edge of. the tool or cutter to gouge the work will be obviated.

The portion of the ba sc of `the main frame 10 which extends under the portion ofthe chain or belt 37 extending across the front of the machine forms it guide 4-0 shown more clearly in Figs. 7 and Sand supports the endless member from its lower face. The remaining portion of the endless member 37 rests upon the upper face of` the base of the main supporting frame 10, so that the endless member is supported entirely from its lower face while the upper face is exposed and is free to engage the detached pieces of 'l coal to form a conveyer for the coal for carrying 1t to any desired pomt at which 1t is to be discharged from the machine, in

a manner to be hereinafterl set forth. The

sprocket 3G and the idler 33 are preferably elevated with respect to the' sprockets 31, 32,

so that when the pieces of coal are.being cnveyed by the endless member 37 they will be slightly elevated.

In order to facilitate the conveying of the pieces of coal by th'e endless member 37 as they fall upon the base 10 of the machine,

the upper face of which latter acts as a platform, the endless member 37 is provided with a plurality oflaterally projecting fingers or extensions 41 which are preferably arranged adjacent the sockets 39 of the tools and extend from the side of the endlSS' conveyer opposite to the side on ywhich the' tools 38 are arranged, and these fingers or pmjeetions 4] project over and preferably rest upon the face of the base l0.

otion is imparted to the endless mem-- ber 37, a'nd to advance the cutters 55o, from the motor 1l, and thismay he accomplished in any desired o1' suitable manner but prel' erably by means of an endless fiexible momber 4.2 preferably in the form of a chain or belt, which passes over the sprocket 43 on the shaft l5 and a sprocket :1t on the shaft 35 to which the sprocket 'JU is secured (sen particularly Figs. 1 and 34). 'lhese sprout:n cts 48, 44, are arranged at an elevation above the endless mel'nber 37,115 shown morcclcarly in Figs. Q, 3 and 4, and secured to and pro jeeting from the endless member 4:13 are arms or fingers 45, any number of which may be rovided, and these arms or lingers 45 nre a apted to engnge the detnclied pieces 41' of the coal as it is brought into proximity to the: arms to movc the pieces ol coal oil' of the platform formed by the upper faire of the hase of the machine, the pieces of ooal being fed into positions to be. engaged by these arms or lfingers 45 by the endless member 37 of the cutters.

In order/to tighten the endless member 37, the axle 34 of the idler 33 is mounted on an adjustable bearing 47 (see particularly Fig. l), which latter is adjustahly held in position with `respect to the base of the machine by a bolt and slot connection 48, 49. An adnistirngr screw." 5() is provided which passes through :rfixed support 5l sind has engagement with the end of the bearing 47 so that by adjusting the screw 50 the bearine 4T and the idler33 will be correspondin ly adjusted.

As the out pieces 46 of the coal are ejected by the, endless conveyer 37, they may be ooirveyed to the cars 52, which run upon the tracks 53 arranged in close proximity to the face 54 ofthe wallv of the coal by a suitable eonveyer which receives the coal when it is thus cjetced. his conveyor pref* erably comprises an'endless chain or belt 55 mounted u on an upwardly inclined snpport 5P andl pa rticularly Fig. 3) an .onfjf ,the sprockets. the sprocket 58, is

immer! tothe shaft $5 on which the sprocket 36 lisisecilred, and

the upwardly inclinedr snppo for pivotal movement "th @peet to the main'supporting fg connection A59. 'Ilnia3ndy provided with .laterifyiglgrJ-ectmg arms or nights 60.111101 an uptight wall or partition 6l is provided on the. support 56, which cooperates lwith thenri 'or fingers 60 to vprevent the pieces:l of coal' 62 being conveyed by the conveyor 55, from falling,r a way from the side Inii-the V1support adjacent the cnrs o2 land also serves as n, means whereby theI pieces of coalrwill be directed into the ears.` The endless conveyer 55 is preferably above arranged below the reor portion of the endless member o7 so that the pieces of' 'oal llo when circled from the pluti'orln formed Irv the far-c of the hase ol the machine, will i'all :into position on tho support 5U to br 7; ronwrrd away by the ronwyrr .35.

The cuttersy 5H are adapted lo out an under kerl' (35i in the wall adjacent the front ol' (he machine and as the machine is advanced7 the forward ond thereof will he projected 75 into this hrri' ,so that the pieces ol' roal which :ire broken down l ih(- rrfiprofnting lool or pick (o he hereinafter described, will l'all info a position to be conveyed by the cndless member 57.

An upright cutter preferably in the forni of an endless chain or belt (it provided with cutting tools UF for cutting an upright korf (5G (shown more. clearly in Fig. l). This endless member (il passes over sprockets U7, a, (38. arranged at the l'ront of the machine, and to one side thereof'` and which spmolrots rotate about horizontal axes (i9, T0. A si'irorhet 7l is also provided in rear of the sprockets (57, G8, over which the endless no. member o4 passes and this sprocket 71 is preferably arranged in a horizontal plane between the horizontal planes of the shafts (i9 and 7U of the sprockets (37, 68, and rotates about a horizontal axis 72. tools are nemovably secured to the endless' member (L by heinff inserted into sockets 73 on the member (i4 and are held against displacement by fastening bolts 74.

The Sprockets (i7, (lo, are spaced from each 10o are preferother to any desired extent but ably arranged so that the foremost run of the endless member (i-l will travel in a plane the plane oft'ravcl of the cutters 38 and also so that the iipright run :it the front 105 ol" the machine will be so arranged that thel cutters carried thereby will travel in an npright plane substantially in line with the upright plane of the cuttings,r edges of the cutters 38 as they travel across the front of 11o the machine. The sprockets 67, 68, nrealso proferublyspnced from each other a sulficient distance so that some of the cutters 65 will extend to the roof of the drift or gallery. Motion is imparted to the upright 115 cutters G5 from the sprocket 71, the shaft 72 oiv which latter receives its motion from the motor ]1 thro-ugh the medium 75 on the shaft 15, which gear meshes with a geur 76 on the shaft '72.

The tension of the endless member 64 may be varied in any suitable manner and for this purpose the sprocket 67 is preferably supported by a member 77 (see Figs. 2 and (i) which is pivotally connected tothe su -12' port 78 of thesprocket A6& by means o n pivotal connection 78". The support 78 is provided'with an ear or projection 79 and an adjusting bolt or screw 80 is pivotally con- .und passes loosely 130 nected to the member-77 The cutting tighten the endless chain. The endless upright cutter thus formed is adapted to` be moved about its point of pivotal support 72 so as to raise or lower the forward end of,

the cutter in any suitable manner but prefer`` ably in a manner whichwill now be de; scribed.

The support 78 is held in position by means of a projection 82 which extends into a slot 83 in an arm 34 which arm is loosely mounted upon the shaft 72. .The slot 83 in the arm 84 is of a length somewhat greater than the length of the projection 82 and an adjusting bolt or screw 85 is provided which projects through the end of the arm S4 and engages the projection 82 so that when the screw 85 is adjusted in one direction, the projection 82 will be moved in the slot 83 to tighten the endless member 64, and when rotated in the opposite direction it will be moved away fromthe projection 82 tb permit the latter to be moved in the slot 83 to loosen the endless member 64. As has been before stated this upright cutter is adapted to be moved about its point of pivotal support 72 by'rotating the arm Bl about the shaft 72 to raise and lower the forward end of the cutter, and in order to secure the cutter at any point of its adjustment, there is provided an arm 36 which is connected with the arm 84 and this arm 86 is provided with a substantially upright slot 87 through which slot a pin or fastening bolt 88 projects. and this pin or fastening bolt is supported by a fixed arm 89 (see also Fig. 6). It will be manifest that by loosening the fastening bolt S8, the arm 86 may be raised orlowered and with it the arm 84, which in turn `will raise and lower the-forward end of the support 7S to the desired extent. When the proper adjustment has been obtained. these parts may be secured in their adjusted positions by tightening the bolt 88.

'In order to hold the machine in position and against lateral displacement, an arm 90 (see Fig. 1) is provided on the main `supporting frame, whicharm is spaced from the side of the `machine opposite to that on which the cutters 65 are arranged and termi,

nates adjacent the face 54 of the wall.. An adjustable screw 91 may be provided on the arm 90 for engaging the face of the Wall.l It will thus be` seen that both of the cutters and the conveying mechanism receive their motion from a single source of powermounted upon vthe `machine ,and this power also serves asf a means ,.for advancingthe machine in thedrift or 'gallery. The under kerf 63 and the u right kerf 66 are simultaneously cut an the machine is so constructed that the source of power and all of the operating mechanism will be encompassed by the endless member supporting the cutters 38 so that none of the operating mechanism will project beyond the sides of the frame thereby permitting the'machine to not only be compactly, constructed but enablin it to be operated successfully and readily Within the constricted space necessary for it to operate.

When the

kerfs

63, 66, have been cut in the wall of the coal, the wall maybe broken down by breaking pieces therefrom and any suitable tool or pick capable of such o eration may be employed. A suitable an eilicient tool of this character will now be described.

Pivotally mounted upon a suitable support 91 (see particularly Figs. 4 and 5) is a tubular framel 92 having a handle 93 by means of which it maybe manually adjusted about its point of pivotalsupport. A reciprocating tool 94: preferably in the form of a pick is provided, one end of which prof jects into the tubnlar frame 92 and this end of the pick is provided with a lateral `projection 95 which extends through a slot 96 insupport 91 and a crank arm 100 is secured` to the shaft 99. This crank arm is preferably provided with an anti-friction roller 101 which is adapted to en age the projection 95 on the tool 94:, whc projection extends through the slot 96 in the frame 92. It will thus be manifest that when the shaft.

99 is rotated, the anti-friction roller 101`on the crank arm 10G. will engage Athe projection 95 on the tool 94 during a portion of the rotation of the crank 100 and will draw the end of the tool 94 into the casing 92, and compress the elastic member 97. When they anti-friction roller 101 1passes out of enf gagement withV the projection 95 on the tool 94, the tension created on the elastic member 97 will, force the operating end of the V tool or pick94 into engagement with the` wall of the coal above the kerf 63 which will brealg down a portion of the wall, as shown 1n Fig. 4. The front or .gb eratin end of the tool 94 may be adjuste rat wil by the' operator grasping the handlev 93 and moving thetool `about its point of pivotal support,

,as will be understood.

Moennig imparted to the Sima 99 fram the motor 11 through the medium of a. gear 102 un the shaft .15 which gear lmeshes with the gear 103 on the shaft 99. With this improved construction it Will be apparent that the entire mechanism protrudes very liti le outside of the path of the cutting ol' Hic tools, thus permitting the track 53 on which the cars 52 run to be close to the face '54 of the wall of the coal and also inside of the props so that the tracks may be moved readily toward the face or wall of the coal as the mining pro resses.

In order to witIidi-aw the machine from the cli-ift or gallery, a drum 104 is provided Figs. 1 and 2) which drum is rotatably supported by .means of an axle 105 journaled in a suitable frame 106 arranged at the rear oil the machine and a cable 107A is wound around the drum, the free end of which is adapted to be anchored to a suitable fixed` support outside of the machine 'I' his drllni .101 is rotated to Wind the cable thereon b means of a Worm wheel 108 connected Wit the drum, which worm wheel meshes vi'ithiil worm gear 109 on a shaftf journaled in' suitable bearings. A gear 111 is secured to the shaft 110 and this gear in turn meshes` with the ge'ar 112 secured to the shaft 72 and for rotation therewith. `A clutch hav# ing an .operating arm or lever 113 may be provided, if desired, for disconnecting the"Y drum 104 from its driving mechanism.
