To aZZ whom z't may concern.- y

Be it known that I, EUGENE MOREAU, a citizen of the Republic of France, residing at Ihiladelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Mining- Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to machines for linining coal, andmore particularly to those which have revolving angers to penetrate the coal, and also to cut horizontal or vertical channels in the same, to separate it and extract it in portions from'the surrounding mass.

The object of my invention is to improve the construction of machines of this kind, lessen their weight, and diminish the coefficient-of friction, protect the mechanism fromV injury, and facilitate their operation.

With these objects inview my invention consists, essentially, in a horizontal guide mounted on a standard tov support theoperative parts of the machine and guide them in boring or channeling; furthermore, inthe combination, with the driving mechanism, of automatic mechanism for causing the auger toV progress in its work in. boring or to channel horizontally or vertically', furthermore, in an improved construction of the auger-driving mechanism; furthermore, in aco'nstruction of the bearing of the auger-supporting part which will greatly diminish the friction .and wear of such bearing; furthermore,l in an iml proved and more compact assemblage of the different elements of the machine and their inolosure in a box or housing to protect them from injury by dust or blows; furthermore, in

a construetionof theauger itself whereby its removal or attachmentmay be facilitated; furthermore, in a construction of the auger whereby the knives may be attached to the helices in a manner best adapted to simplify the manufacture of these knives, and, finally, in certain novel details of construction. l

In the'accompanyingdrawings, which forni a part of this specification, and in which-like. letters of reference 4indicate corresponding parts,

.ing spindle.

Figure 1 is a perspective view of a ma-A chine embodying my invention, showing th horizontal guides mounted upon a standardin f a manner to be horizontally and vertically movable, and supportingfthe operative parts vof themachine,(shown housed,) and showing the shaft and clutch ofthe automatic auger-directing mechanism with the warp chain or cable, the auger portionbeing retracted. Fig. 2 is a side elevation) with `portionsin section, showing the horizontal guides' on the standard', thev auger portion being extended, and showingthe construction of the driving mechanisrn and a portion of the .automatic augerdirecting mechanism for causing progression or lateral or vertical cut of the auger, showandthe fixed spindle with itstapering projection, the auger-bearing sleeve, and the auger proper, and showing the means for lengthening or shortening the standard. Fig. 3 is apian View of the machine, showingthe Ymachine making a lateral cut, and in dotted Vlines the position of the machine afterhavin'g cut a horif- 'p l zontal channel to the left of the starting-'point'. Fig. 4 is a longitudinal vertical sectionlof the auger portion of the machine, `displaying in detail its construction, showing at the center the revolving spindle; showing,also,the outer bearing of the fixed spindle, with a part of the body and the tapering portion of the iixed spindle and the means for die in place; showing, also, the auger-bearing sleeve and the means for fixing this to and causing it to turn with the revolving spindle and for retaining it and the fixing means in place, as well as the means for keeping the fixing and retaining `,means in place and for ing the revolving auger-spindle and its bearing g holding this spinpreventingescape of oil,=and also showing the i auger proper and the means for attachingjthis to the auger-bearing sleeve.

B represents a standard consisting ofa xied portion, b, having a claw on the outer end, a fixed screw-nut, b', at its other end, and an intermediate sleeve, b2, provided with collars or clamp-rings b3, and of a movable portion or screw, b4, having a claw on its outer end and bearing a hand-wheel, b5, by which it can be turned in the nut to lengthen or shorten the Standard. The screw-nut b is preferably split and provided with a,bolt by means of which sufficient pressure may be exerted upon the screw to hold it in place when desired.

The horizontal guide Ais slung or swung to the standard by means of arms C, which are attached to the top and bottom plates a2 at c c', and are pivoted to the standard upon its sleeve by a bolt passing through a boss, C2, integral with the upper collar or clamp-ring lof' the sleeve. A heelpiece, a3, on the under plate a2 rests against the lower part of the sleeve b2. The sleeve can vbe secured at any height on the standard by means of the clamprings b3. It will be obvious that by the attachment of the guide tuo the standard this can be swung laterally on the standard orbe raised vertically on the same.

Between the sides of the horizontal guide is the operating mechanism of the machine, and this is contained in a box or housing which serves to protect it from injury by dust or by blows. D designates this box or housing, and it is composed, preferably, of two castings held together by bolts. The box is retained in the guide A by longitudinal flanges d at its upperand `lower margins, which are planed to work smoothly upon the edges of the sides a 0f the horizontal guide. A tightening or locking device, d d', of any suitable construction, holds the hox and the operating mechanism firmly in position at any desired point on the guide. The upper part of the box is provided with a removable cover to enable examination of the internal parts of t-he machine and facilitate their lubrication.

As before remarked, the box contains the operating mechanism of the machine, and this consists of two groups-one, E, for driving the auger, and one, F, for guiding it--causing it to progress longitudinally or penetrate, or to cut horizontally or vertically-that is to say, laterally or up and down.

Referring to the driving group, e designates a inain shaft, having crank-wheels e fixed at each end and passing through bosses e2, bored out to receive it and located immediately under the cover. Vithin the box and fixed upon the shaft e is a bevetwheel, e3, which engages with another bevelwheel, et, fixed upon the upper end of a counter-shaft, e5, to the lower end of which is fixed another bevel-Wheel, e, which meshes with a further bevel-wheel, e7, fixed upon a shaft or revolving spindle, g, belonging to the auger portion G of the machine.

Referring to the guiding group, on the spindle g is a worm, f, which engages the teeth of a gear-wheel, f, which gear-wheel is the first of a train ending at the shaftf. This shaft carries a chain or cable gear, f3, connected with it by means 0f a friction-clutch,f, operated by a hand-wheel, f5. A'warp chain or cable, f, runs at one end through the chain gear, and is secured at the other end either at the upper and outer extremity of the guide A, as shown in Fig. 1, or at any other place convenient for the desired movement of'the auger.

It will be clear that as the crank-wheels e are turned rotary motion will be imparted through the intermediate gear to the spindle g, and that this in turn will give motion to the shaft f2 through the intermediate gear, causing this, when the warp-chain is properly held, to wind and pull upon it.

The revolving spindle g is held at its rear end, where it is also provided with thrust-col` lars in bearings bored out to receive it in a bracket, g', at the rear of the box, and at its front end is held in a stationary spindle, g2, which is fitted to and runs through the forward part of the box and through a bracket, g3, a nut, g4, holding it firmly in position. A4 part of the stationary spindle g2 projects considerably beyond the front end of the box, and this part has the shape of an elongated cone in order to serve as a bearing for a tapering sleeve, g5, which revolves upon it. This tapering sleeve g5 is fastened to the spindleg by means ofa key, 06, which fits into a slot cnt through the end of each. To hold the key in place and thus keep the sleeve fixed to the spindle, a nut, gl, is screwed on the end of the spindle g against the key, and to prevent the assembled nut, sleeve, shaft, and key from coming apart, and also to form a tight joint, so that oil fed to the inner part of the tapering sleeve g5, as hereinafter described, cannot escape, but will be led from the tapering sleeve g5 upon the revolving spindleg through a spiral groove, g8, a cap, g, is screwed upon the end of the tapering sleeve.

The auger proper is designated by the letter G. It is so turned on its interior as to tit the outside of the tapering sleeve, and is held in place upon this sleeve by means of a hinged bolt, gl". The auger has regular helices g, and to these helices are riveted the knives y.

In a tapering auger the angle of the helix with the axis varies from end to end, provided the thread of the screw remains constant. Therefore a form of knife suitable for the rear end of the auger could not be of the proper shape for the outer end if the helices were of a uniform pattern throughout its whole length.

In order to use only one standard knife, the difference in the angle of the helix at each point where a knife or cutter is attached must be corrected by shaping the helix at that point according to the variation. To this end a boss, g, is provided at each point where a knife or cutter is to be riveted, and the face of each IOC) helices at the point of fastening of each knife as follows: The standard B is first or cutter permits the use 0f only one pattern of these knives or cutters, and thus greatly simplifies the manufacture of these knives or cutters.

` The auger portion of the machine is properly supplied with oil at the circular space g14 between the rear end of the tapering sleeve and.

the stationary spindle, and the oil is fed forward by the movement of the sleeve on the stationary spindle between it and the supporting-spindle along a spiral groove, g8, into the cap, whence it passes .back ward along the revolving spindle.

The operation of my coal-cutting machine is placed in position at the proper distance from a bank of coal, as shown in Figs. 2.and 3, and the warp chain or cable f6, which engages the vchain gear f5, is fastened at the end of the guide A say on a ring there. Thebox D is left/free to move upon the horizontal guide by release of the tightening or leases the pressure of retaining device, holding the box Dinfplace. The friction-clutch fL is made to act by means of the hand-wheel f5, and then the operator turns the crank or cranks'e. As'the` auger rotates, the chain chain or cable f, thus forcing the mechanism and the auger forward and causing the auger to penetrate the bank, the dbris resulting from the penetration being fed out by the action of the helices. After the auger has been allowed Ito bore nearly its entire length theY motion'oi' the'crank e is stopped, and the box is fixed in position by means of the tightening or locking device d. The warp chain or cable is then detached from the end of the horizontal guide, i's`"passed around a pulley on the box, and is attached to any suitable point adjacent to the machine, either to a wall of the bank or to a post.7 If the crank be now again set in motion, the movement of the machine will be one of rotation uponV the axis of the standard B, the-drawing upon the warp-chain i 5 5 f by means of the chain gear fal'effecting this result. Y

It is evident that by simply attaching the chain to a point on the side of the coal-cutter opposite to 'that at which it has just been attached the movement of the machine may be reversed; hence the movement of translation of the machine is always toward the point to which the fixed end of the Warp-chain is secured. l

If it be desired to cut'avertical channel, the

. warp-chain should be fastened to the roof above the outer end of the horizontal guide,

locking device d', which re-V ofthe clampor other forml gear pulls upon the warp and the auger would then rise, describing a vertical circular channel having the axis of the boss c2 for acenter..

It isV clear that with the warp-chain and chain gear theauger can be made to bore the coal, and also to channel it vertically or laterally, simply `by guiding'the saidwarp-cliain and attaching its fixed end according to thev work to loe done. l

It will be apparent that the chain feed will be equally effective should' the machine be placed upon a guiding device other than the horizontal guide A and the standard B, and I with either of these particular parts.

All the gearing which is lused to transmit the .motion of the cranks to the auger and also to the warp-chain being entirely inclosed, the dust of the coal cannot enter the bearings and interfere with the lubrication; and, furthermore, by being so incl'osed the mechanism is perfectly protected from vblowsy and other causes of injury.

Having thus fully described my invention,

87o do not therefore limit myself to its connection Y what I claim as new, and desire to secure by 1.
