The same part is designated by the same reference sign wherever it occurs throughout the several views. l

l will first describe the construction,

function and mode of operation of my improved coal-mining ap aratus, particular reference being had to tig. 1, wherein reference sign A designates the framework, upon which is mounted a supplemental frame as twell as several, other .operative parts of the apparatus, as will more fully electric motor, or it may be arranged as shown in the drawing and as will be more fully explained hereinafter.

A gear E, preferably a worm, is shown in Fig. l arranged to be driven bythe motor C, the worm E being mounted loosely on the armature shaft C of the motor. The gear E meshes with and `drives a gear F, preferably a Worm wheel, mounted on a shaft G which is arranged to extend transversely across the machine and which carries suitable gears at the outer ends thereof. These latter gears are preferably sprocket ears engaging the sprocket chains 200, as s own in Fig. 3. These sprocket chains are geared-to the traction wh'eels B, B, so that when the shaft G is rotated the entiremining machine may be moved in-one direction or theother. y

It Ishould be understood that I prefer to connect the sprocket gear;g driving mechanism between each of-the 1outer` ends `o f--,the

This clutch JK, which is shown in sectional elevag, tio-n in Fig. 1 and in plan in dotted lines in Fig. 3, may be controlled by asuitable operating lever, as shown at K in Figs. 9 and l1. Y, The lever K may be pivoted to a pedestal 218 mounted on the main frame A,

0 as shown in Fig. 9.` lBy suitably actuating or Areversing the motor C, the traction wheels may be driven in the desired direction to advance the mining machine from one part of the mine to another, or to adir. vance the mining machine to its work or to withdraw the mining machine therefrom, or to move the mining machine slowly forwardV during the mining and loading operation. VThe speed of the motor, if the motor is a series-wound electric motor, may be automatically regulated according to the load,

. the machine advancing slowly when meeting with considerable resistance, and being moved faster when the load on the motor is 72'5 reduced.' By suitablynoperating the clutch K the driving gearing for the traction wheels may be thrown into or out of action at will.

lt should be understood that by means of 3o the'traction wheels, the entire mining ma- .chine ma' v be moved to the point where the eutters,`. ereinafter described, are placed readiness to break down coal from the mine wall, and that Ithe machine may be fed vforward as tast as the coal is 4broken down and removed. However, since thetraction .wheels form a yielding means for advancing the machine, slipping ci the traction wheels may ,occur on the mine floor when the tendk0 ency is to overtan the capacity of the cutters by their encountering particularly hard material. Where the material can be easily cut, the traction wheel driving' mechanism alone may be'suiiicient to resist any backward slipping of the mining machine. When i" coal very diiiicult to out is reached, it may ner a pair of screw rods M, M, as shown in 3, each being provided in its near end With a pivotal connection to a pair of bracing arms N, N, in toggle joint fashion, each ivotallyl connected' arm being in turn loosely to an anchor s oe O, as shown in Fig. 1. The members of each pair of shoes 0 may, if desired, be suitably serrated on their engaging surfaces, and respectively arranged to engage the walls of the room or the door and roof, as clearly shown in Fig. 1.

o 'andere "jywm this construction and arrangement, it will be seen that when an endwise pressure is, exerted upon the screw rods M in a direction op, osite the forward path of the machine, t e toggle arms N will beput under stress to, force the. anchor shoes 0 away 'from each other and into engagement with' the door and roof or the walls of the mine chamber, thereby securing and firmly' anchoring the entire machine against rearward movement. 1f the pressure is continued to be exerted longitudinally of the screw rods, the entire minin machine is advanced or ted forward slow y, away from the position oi the anchor shoes and in a direction to advance .the forward limit of operation of the coal-cutting mechanism. 1n practice, when the anchor shoes are arranged to engage the floor and roof of the mine chamber, 1 prefer to employ two or more screw rods, and hence also two or more pair of toggle rods M and shoes O, for the reason that by suitably` arranging one'pair of these anchoring and feeding devices on one side of the machine, and another pair on the opposite side, as clearly indicated in Fig. 3, l im enabled to straighten the machine in case its course departs from a straight line. Therefore, control ofthe forward movement and the direction of the path of travel may be easily accomplished by throwing one or the other set of anchoring and feeding devices into or out of action, as occasion may require.

l will now describe a suitable and efficient construction and arranagement for exerting the/pressure above mentioned longitudinally upon the screw rods M, whereby the machineis first anchored and then fed forward to advance the forward limit of operation of the cutters. Inthe particular forml shown, I provide a gear P on the shaft C of the motor C, as shown in Fig. 1. The gear P meshes with the gear L, which in turn meshes with the gear L', and the latter meshes with the gear Q. This train of gearing is shown in Figs. 1 and 3. A shaft S is suitably mounted on the upper part of the main frame of the mining machine,to eX- tend transversely across the same, as shown in Fig. 3. The transverse shaft S carries a gear T, which meshes with a suitable gear U, preferably a worm, mounted on the shaft R. An internally threaded nut or sleeve 14 is mounted in a suitable bearing connected to the main frame A, so that said nut will engage a screw-threaded rod M. It should be understood that there is one of these internally threaded nuts or sleeves 1li on each of the screw rods M, M. By rotating said nuts 0r sleeves 14 in one direction or the other, the desired pressure is exerted upon the screw rods in one direction or the other to effect an anchoring of the machine and the feeding thereof, or to effect a release of rotation of either' the gears 18 or the immerse d, one screw rod. The nut 14 carries or has formed integrally therewith two gears 15 and 1.6, as shown in Fig. 1. Upon a suitatfly and convenient-ly mounted shaft 17, its wn :in 3, are loosely mounted .ars` 18 and 19, the gear 19 being of rely large diameter with respect to the gear The gear 19 meshes directly with the 16 of nut lll, as shown in ijs. Il. and 3, while gear 18, which is of relatively small diameter, engages and drives the gear 15 through an intermediate idler gear 20. From this construction, it will bo seen that when the gear 19 is idle and gear 18 is acting, the sleeve 14C Will be slowly rotated, in one direction, namely, in the direction to elft'ect a longitudinal pressi on the screw rod il/I, to cause the anchor :ai ice to grip the roof and door or side Walls oit the room and to effect a. :leedine of the machine forward. If the gear 18 is idle "d the in: 19 acting, the sleeve 111 is m re rapidly rotated in the opposite direc tion, and an endwisemovemcnt of the screw rod in the opposite direction is eilen-ted,

thereby releasing the anchor shoes O.

.tiny suitable and welltznown form of cluich S21, as shown in l? ig. 1, may be cm ploycd to throw either gear 18 or gear 19 into or out of action at will. i worin gear mounted on shaft 17, as shown in Fig. 3, arranged to engage a `vvorm on the transverse shaft S. By means ol a suitable and conveniently arranged clutch Q4, as shown in Fig.' 3, the mechanism for actuating the anchoring and feeding means on one side of the mac line may be thrown into or out of action at will. The clutch E24; may be omitted, if desired, however, and the rod ri made' continuous, so that Whenever the motor C is operated. motion will be trans mitted from the shaft l to the worin gearingr ll; T, and thence to the-transverse shaft" S and. the worms at the ends thereof. In this manner, 'whenever the motor C operates, the transverse shaft S and the short shaft 1'? are continuously rotated. The clutches 2l, when in central position, will not ell'cct gears 19. It is therefore obvious that the ineclianisin for actuating the anchoring and t'ccding means at the sides o1 the machine may loe vthrovv'n into or out ot action at will. independcntl)7 of each other, by means ot' the clutches 21. It is also obvious that it thc clutch 21 at one side of the machine is left in central position, and the clutch 2l on the othei side ot 'the machine is thrown in, so as to actuate tbl gear 18, the machine at that side will be moved 'forwardl slowly while being braced by the anchoring shoes O on both sides of the machine. In this way the forward movement or direction of travel of the entire mining machine may be easily controlled. The loose pivotal connection between the toggle links N and the slices O will, of course, permit gradual turning of the mining machine while being advanced,

and while the bracing toggle mechanism remains in operalive osiliion. While I have shown the screw rof s M, in Fir'. 1, as being supliorted on the main frame )y means of` the bearings 14, which may be of any desired length, additional supports extending from the rear portion of the main frame in the form of brackets may be provided if desired. Such brackets may be rigidly con nected to the main trame and extend rearwardly therefrom, with bearings at their upper ends encircling the screw rods Mg M, particularly where the threads of suoli screw rods are squared or rectangular in longitudinal cross section. .From the foregoing description, it will bc seen that when the niachinc has been advanced to the limit ot' the ieed screws M, the said screws may be moved quickly in the opposite direction to advance the anchoring shoes to a point closer to the machine, by reversing the clutches 21. .In this manner, a fresh grip of the anchoring slices is secured, ,after which the feeding action may be repeated. Any suitable and Well-known provision may lie made, it desired, for preventing the-up per toggle links N from falling below a limited distance "when the screw rods M are moved forwardly and the shoes O-,released from the roof of the mino chamber.

Upon the front end of the framework of the main iframe A, I mount a frame or platform 25, to .be held by the main frame substantially parallel to the floor of the mine, slightly above the saine or partly resting thereon. The platform 25 is therefore mounted in such relation that it will occupy a horizontal plane, or a plane substantially parallel to the fioor'o the mine, so as to readily enter a floor kurt or horizontal 'kerf cut alA the base oi' a mine wall by another machine. The frame or platform, 25 may be detachably connected to the lower front end ot' the main traine, as indicated at 5209. in Figs. `l and 3. I prefer to rigidly attach the middle section onl'voi theplatform Q5 to the main `frame A, by means permitting the entire platform to be detached from the main lianie. I prefer to construct the platlorm Q5 of three sections, 11, i2 tachably bolted together as shown at 441, 44', in Fig. 2-5. In order to withdraw the entire mining machine trom the mine wall. it may lic desirable ci' necessary, in somo instances, to remove the sections 4l and t3 of thepletfoi-1n and fold them onto the section 142,95,

as to facilitate the transportiition of the ma chine from place to place.

n asmuch as thv and 43, de,

latforin is nearly as wide as the mine chamer, such folding of the platform will avoid undue friction against the walls of the mine. The shortening of the `width of the front portion of the mining machine facilitates the withdrawal thereof at considerably greater speed than when the side sections L11, 13, together with the side plates attached thereto, are left in position.

In the present embodiment of the inven-` tion, the means for breaking down coal from the mine wall is combined with the means. for Yremoving the broken down coal. An under kerf and side kerfs are first produced by another machine, and then the mining machine herein disclosed is `brought into a position with the platform 25, extending into the under kerf. The cutters 101 are then operated to break down the body of coal above the under korf, after `which the scoop 58 is operated to take up the material and deliver it onto the carrier 88, shown more clearly in Fig. 1. It is desirable to first snub oif the lower corner of the wall of,

the undercut coal, because in som'e instances the weight of the coal above will thenhave opportunity to break down the coal onto the platform, after which it may be broken up hy the cutters, if necessary, and then loaded into mine cars. The work of loading the coal into the mine cars may be carried on intermittently with respect to the breaking down operation.

The breaking down apparatus comprises a supplemental frame 57, which is pivoted at 56 to the main frame, and is supported at its forward end on the roller bearings 81. It will thus be seen that the supplemental frame 57 is pivotally mounted on the main frame for lateral movement thereon. rlhe forward portion of the supplemental frame 57 carries the mechanism for controlling the reciprocating movements of the cutters and the tilting or rocking thereof in vertical planes; In order to effect the reciprocating movement of the cutters 101 mounted on the support 58, the shaft 70, shown in Fig. 1, must be rotated, because it carries the gears 71, as shown in Fig. 10.. These gears 71 mesh with the rack bars 68, 68, mounted to slide in the guides 69, which are rigidly attached at the sides lof the trough 87.

The means for controlling the Vreciprocation of the cutters 101 comprise a bevel gear 78, at one end of the shaft 70, supported by an extension from the supplemental frame, as shown in Fig. 3. The bevel gear 78 meshes with two additional bevel gears and 76, between which is mounted a clutch( 77 on a shaft 74. operated by means of a lever 222', as shown in Fig. 3, or by means of a rearwardly eX- tending lever 222, as shown in Fig. 9. l/Vhen the clutch T7 is thrown in one direction, the

The clutch 77 may be" support for the cutters 101 will be moved forwardly, and when the clutch 77 is moved in the 4opposite direction the cutters 101 will be retracted.

The'source of power for operating the cutters t6 tilt them vertically and toy move them laterally7 and to reciprocate them, comprises the electric motor C, which, whenever it operates, continuously rotates they gear L and consequently also the hollow shaft 61, through the universal joint 60 and the sliding connection 62. Preferably, this sliding connection comprises a rod, square in cross section, iitting into a corresponding opening in the hollow shaft 61. 'On the hollow Fig. 3. lThe A'hollow shaft 61 is suitably mounted in bearings connected to the supplemental frame, will be free to rotate but will be kept from sliding either vway in such bearings longitudinally. The gear 7 2 being in mesh with motion is transmitted to the latter whenever the electric motor C is operated. The bevel gears 75 and 76, being mounted loosely on the shaft 74, will not rotate until the clutch 77 is thrown in one direction or the other.

ln order to control the rocking or tilting of the .support 58 for the cutters 101, the said support is pivoted at 59, 59, to the outer ends of the rack bars 68, as shown in Fig. 3. These pivotal connections may comprise piutles or gudgeons fixed to the support 58 and extending into Vbearings at the outer ends of the rack bar 68. To one of these pintles with two beyel 63. Between the bevel gears 64 and 65 is from the rack bar 68 at that side, and cannot be moved longitudinally. The shaft 6 3 which is preferably square ingress-section and fits into a corresponding opening" in the forward end of the hollow shaft 61. rlhis sliding connection between the rod 63 and the hollow shaft 61 permits' the control of the tilting of the support 58 to be retained, whatever the forward position of the cutters may be, within the limits of the operation of the mining machine. ever the hollow shaft 61 is rotatI d, motion is transmitted to the rods 63 and 63, and

shaft 61 is mounted a gear 72, as shown in' so that` said hollow shaft the gear 73, which is iXed to the shaft`74c,

mounted a clutch 66, which may be operated the short lever 211', shown in) shaft 63 is mounted in bearings extending.

is fastened a bevel gear 67, which meshescw gears 64 and 65 on the shaft whenever the clutch 66 is thrown in, the gear 67 will be actuated to tilt the support 58 on its pivots 59, 59.

The apparatus for controlling the lateral movements of the cutters 101 comprises bevel gears 84 and 85, loosely mounted on the shaft 74. A clutch 86 is also mounted on the shaft 74 between the gears 84 and 85. Meshing with the gears 84 and 85 is a horizontal bevel gear 83, which is connected to the upper end of a short vertical shaft mounted in bearings connected to the supplemental frame 57, as shown in Fig. 9. At the lower end of the shaft carrying the bevel gear 83 is a spur gear 83;, which meshes with the arcuate rack 82. This ar-v cuate rack is mounted on the main frame at 82', 82', as shown in Figs. 3 and 4. The clutch 86 may be operated by means of a short lever 220', shown in Fig. 3, or by means of a long lever 220, as shown in Fig. 9. The lever 220 is connected to a shaft 219 mounted in vertical bearings attached to the supplemental trame. W hen theclutch 86 is thrown in one direction, the spur gear i3 travels on the arcuate rack 82 to move the support 58 and the cutters 101 thereon laterally in a corresponding direction, and when the clutch 86 is thrown to the opposite side the support 58 and the cutters 101 vill be moved laterally in the opposite diyection.

Preferably the support 58 for the cutters i01 is in the form of a scoop, so that after sulicient material is broken down for rcmoval this scoop may be so o erated as to take u a load and move it bac rwardly, and then oliimp lit onto the carrier 88. In the supplemental frame 57, a trough or way 87 is mounted as shown in Fig. 1. This trough upwardly inclined from the forward end thereof toward the rear, and its forward end is so arranged with respect to the scoop as to receive the coal therefrom when the scoop is tilted backwardly a sufficient distance. The forward end of the trough or chute 87 is preferably provided 'with an. in-

-clined cross piece 212, as shown in Fig. 1,

to direct the material from the scoop onto the belt conveyer 0r carrier 88, which delivers the material into a mine car, as shown in Fig. 1. As illustrative of the idea, I have shown an endless belt, band or carrier 88 arranged upon rollers shown mounted on the shafts 89 and 90, respectively arranged at the upper and lower ends of the chute or trough 87.

The apparatus for controlling the op ratioi of the carrier 88 comprises a gear 92 fixed to the shaft 90, as shown in Fig. 9. The gear 92 meshes with another gear 91. above thc same. The gear 91 is fixed to a shaft 93, to which is also fixed the bevel gear 94, as shown in Fig. 3. The bevel gear 94 meshes with the bevel gear 95 which is mounted loosel on the shaft 74. A clutch 96 on the sha t 74 may be operated by a short lever 224', shown in Fig. 3, or by moans of a long lever 224, as shown in Figs. 9 and 11. The long lever 224, when operated, turns a. vertical shaft 223 which is mounted invertical bearings attached to the sup lemental frame. When the clutch 96 is t irown into engagement with the gear 95, the latter is rotated and transmits motion to the gears 911 and 91, the latter then transmitting motion to the gear 92 and the shaft 90. So long as the clutch 96 remains in oper ating position, the belt conveyer 88 will continue to operate, provided the motor is o e1'- ating to continuously rotate the hollow s aft 6l and the gears 72, 73 and the shaft 74.

The cutters 101 may be adjusted to different locations on the support 58. For this purpose, holes 301 may be provided in the cutters 101, and holes 302 in the support 58, for receiving bolts 300, as shown in Fig. 3. When the support 58 is in the form of a scoop, I prefer to mount the cutters on the bottom of the scoop, as shown in Figs. l, 2 and 3, so that the forward ends of the cutters will project only a sort distance beyond the forward edge of the scoop. When the cutters are thus adjusted, they will interfere but little, it at all, with the scooping operation, 4because as shown in Fig. 2, when the scoop is moved over the platform its forward edge will occupy a position near the upper surface thereof, and therefore be capable of scooping up all the coal in its forward path of movement. When, how ever, the cutters are to be used mainly for breaking down the material, or when it is desired to first break down the material and then readj ust the cutters before the scooping operation is performed, the cutters may be adjusted to such a position as shown in Fig. 6. The cuttersare here shown snubbin oil' the lower corner of the wall of the un ercut coal, thereby changing the hori zontal kerf into a V-shape. Such a V-shape ker facilitates the subsequent breaking down of the coal, and in some instances af fol-ds the upper body of coal an opportunity to break down of its own weight. This Snubbing operation is accomplished auto matieally by power-actuated mechanism under the control of manually-operated levers, as hereinbcfore explained. Whenever desired, the snubbing cutters 101 may be unbolted and easily removed, or moved to a new position. The snubbing requires the ex` penditurc of only a small amount of power, which can readily and easily be applied through the reciprocating mechanism.

Obviously, when the cuttersl 101 arc in snubbing position, as shown in Fig. 6, the support for said cutters may be advanced and retracted by power-operated means, and the operation repeated as often as desired,

'from the position shown in Fi vancement of the entire mining up into pieces y scoop and conveyer to` handle.

and 4atufvarious angles, by moving the sup-l plemen'tal frame laterally in either direction g. 3. It is therefore evident vthat the cutters 101 are in reality reciprocating tools for breaking down the material above an undercut vor lower kerf in a mine wall. if desired, the reciprocation or the cutters 1.01 in -various angular' directions may be carried on for breaking "down all the material above the 'undercut up to the root of the mine chamber,

so las to leave sucient clearance for 'the tidmachine or ,of a'lxerf-cutting mining mac ine into the mine wall. rl`he snubhing cutters are capable of this o eration, particularly when thesimpport 58 t ereior is made of sucient lengt and the cutters are adjusted in their extreme forward' positions, Vas shown in Fig. 6. lt should also be understood that the reciprocating tools 101 may in some instances be used to break up material broken down in large blocks. Therefore, in such cases where the coal is dislod ed by its own weight, the reciprocating too may be used to break it Within the capacity ci the In some instances, the platform 25 may be left entirely detached, and the bottom of the kerf usedas a platform for the scoop.

'in such event if the cutters dig into the coal Hoor when t e scooping 'operation is `performed, the cutters 101 may be adjusted to their ineective positions, as shown in -Fig 11, and the' bottom of the scoop 'made horizontal.

inasmuch as the reciprocating tools iOlf partake of the vertical turning movements of the support 58, and the lateral movements ot the supplemental conveyer it will lbeset-in that lthe cutting tools ma be adusted to various angles 1n vertical p anes un towerious angular positions laterally, so as to cornmand the entire cross-sectionalvarjea of the room and .provide suiicient clearance lfor the continued advancement of' the mining machine disclosed herein, or of another mining machine used for the purpose of roducing additional and deeper kers in t e mine wall. This is obvious rom ari ins ection of Figs. l and 6, from which it wil be seen that the slicing od of the underside of the body of coal above the. under cut may be continued up to the roof of the mine chamber. lt should also be observed that the carrier, 'by moving with the supplemental fra me, always remains in alinement with the scoop or in the same vertical plane there` with, no matter what the lateral position of the scoop may be. Furthermore, since the pivot 56 is near the rear end of the sup plezncntal conveyer, the carrier will continue to deliver the coal to the mine car for all lateral positions of the scoop, and the scoop need not be brought back to central operating the severa as above dcribed, "andi such" fornaci-fot meten for muy rmliieel renewal rte'yr electriomotor'C for f 1 .of the machine to fuse'f-it becomesI a matter [of convenienceto supply the o eratinigxeurrent thereto in a manner-that w' l permit of the advancement of the machine farther and 'farther into the hed of' coches the latter is broken down within the limits of "the kerirs produced by another machne 'As anillustrative form o'operative means accomplishing this def red object, l have shown suitable electric conductor D leading from' the motor C to 'a reelv 102 where this conductor malies suitable slidingv electricalv connection with the inner end of a Hexible connector 103,. in.

When the mining machine is transported to another part ot' the mine, the conductor 103 will be taken up in accordance with the retracting of the machine, Even when the mining machine advances slowly forward during the breaking down operation, `the reel mechanism pays out the conductor 103 in accordanuzc with such n'iovement. However, it may he desirable=to move the machine forward intermittently. The mechanism shown is such that when the scoop and conveyor are opor ated, the shaft R is also rotated.

By means ol this arrangement, the reel may be operated to take up slack in the conductor 103 cvcn when the mining machine is not lieingr moved over the mine tloor. The lever 215, as shown in Fig. 11, may be located in a couvcnient position for actuation hy a .single operator standing on `the truck platform.

In the practical operation o'f mining, it is important t0 form rooms or chambers parallel with each other and a distance apart about equal to the width of the rooms.y thus leaving intervening' Walls or pillars ot coal of substantially the same thickness as the Width of a room, as supports for the coal above. After the particular portion of the mine beinf'worked has been exhausted, it is desirab e to mine the coal *forminor the pillars. In such cases, it is necessary to undercut only the pillars, as the side cuts have already been made. This undercutting,r may be performed by a se aratc machine, but the breaking down of t e coal, and removing the same, may be done by means "of the machine disclosed herein, particuarly when side plates 120, 120 are bolted lor otherwise secured tothe platform 25, as

shown in Fig. 3; The side plates 120 may, in some instances, be detachably cannected to the main frame, out ll prefer to detachably connect them to the platform 25, so that when the sections 4l and 43 are de* tachcd, the sido plates l2() may he removed at the same time.

However, it' an additional korf is produced in vertical position, both 'side plates could be retained in position. When. the mining.,r machine herein disclosed is being' used to break down a pillar, the side plates act as collectors or Acuiden to pre-- vent the material as hroltcu down from spreading od the platform ln the saule Wa when the maehincv is uned as a long wall mining machine, the outside side plate maintains the material on the platform within the field of operation ot the scoop.
