To all whom t may concern:

Be it known that I, EDWARD S. MCKINLAY, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Mining Machines, of which the following is a specification, reference being had therein to the. accompanying drawings. f .4 -v V Figure 1 is a plan viewof my machine', showing the manner f attackingvv the coal. Fig. 2 is a section on linec, Fig. 1. Fig. 3 is a section on line y y, Fig. 1. Figli-is a section on line fr', Fig. 8. Fig. 5 is a longitudinal section o f vone of the drill-cylinders, enlarged.

rier; Fig?? is a'orossfsectionthrough the out Fig. 8 is an enlarged view of the carrier feeding cylinder with its adjacent parts. Fig. 9 -is a view looking in the direction of the arrow in Fig. S. Fig. 101is a section on linea2 m2, Fig. 8,. Fig, 11 shows part of the carriage-feeding mechanism. Figs. 12, 13, 14, 15, 16, and 17 show details of the saine. Figs. 18, 19, and 2O show a modiied form of the chain-driving devices.

A 'A represent the side parts of a frame adapted to be made stationary temporarily and to support the movable and operative parts of the apparatus. As showmthese tubes and the framework of which they constitute a part can be extended from time to time by connecting sections endwise one after the other, in the manner described and shown in an earlier application, Serial No. 279,696, filed by me July 11, 1888.

B B2 are cross-bars having eyes or short sleeves'B l', adapted to iit the tubes A and to be secured thereto by set-screws I).

B3 B3 are standards for supporting .the

frame, they resting on pedestals Z1 and being threaded and provided with cranks or han dles at h2 for rotating them in the threaded ears 134011 the eyes or sleeve B. On the frame so provided a movable carriage is mounted, having a plate C, with eyes or supporting sleeve C surrounding side parts A A.

o c are antifriction-rollers in chambers formed in the sleeve or eyepieces O and restf ing on side parts A A.

. From carriage C is supported the revolving table or wheel D, supported on a pivot D. .It has peripheral worm-teeth engaging with worm D5, rotated by bevel-gear D and hand-- wheel D4.

From table or Wheel Dy is supported the driving-cylinder E, which pushes the cutters inward and draws them out. The piston E projects toward the material to be cut. On

.oit is supported a frame or cutter-carrier G, to

which the drills or several cutting mecham isms Il Il are secured. These drills are of a class now well known, the cutting action of each being effected by exceedingly-rapid reciprocation of a hammer Il', driven by airpressure against a drill-holder H2, the cutter being shown at 7a. Air is fed to and eX- hausted from the ends of the cylinder alter- 4nately. Y A Y nThe frame or'carrer Gr is shown as made of two plates g g, bolted together and provided with air-ducts g2 g3. The duet g2 is connected to the feed sides of the pistons through ports, as at g5, and the exhaust-ports are turned toward the cutters, so as to assist in throwing out the cuttings. The carrier-plates g g may be cast with longitudinal grooves in their inner faces to form the air-ducts g2 g3, and the lateral ducts at g5 g6 may be formed by drilling. The air passes to the duct g2 through a pipe l, here intended to be a flexible hose,I there being a valve at l' to regulate the admission of the air at the end z' of duct g2.. The duct g3 receives air from pipe J through valve JU rllhe air so admitted can be used to assist in Ycleaning the cuttings when suclr cleaning is necessary, and at other times this duct can be closed by the valve J. The valves I and .l I may be dispensed with, and the valve at j' ji used instead thereof. y

K is a reservoir or pipe connected by a hose K with a stationary feed-pipe arranged at some suitable place near where the cutting is to be performed. The reservoir or pipe K and couplin g for the connection of the various valves .and pipes or hose which are to'carry the air in the several directions are provided with valves, (shown at j j' jij) together with the aforesaid pipes I J L L. 'Through pipe L passes the air to cylinder E, there being a 'pipe at M, extending to the ports m m' and communicating with the pipe L through av valve L2. Valve L2 has a handle m2, which is adapted to be thrown alternately in opposite directions by parts carried by the piston E'.

E2 is a cross-head onpiston-rod E.

Bar N has projections n2 as in the path of handle m2 of valve L2, and said projections alternately admit the air through the opposite In this way the parts carried by the piston can be caused to automatically eect the advancing and receding thereof. f course other devices of any suitriage C and the parts supported thereon a step-by-step` movement forward.

Y S is a cylinder, the piston-rod S of which is pivot-ed at s to carriage-plate (l. The air passesfrom pipe K tliroi'igh hose L, valve t, and pipe l to eylindeiyS. The piston is prevented from moving until the cutters are drawn back by piston E'. Just as they reach the onterinost point in their travel the aforesaid cam N pushes up on rod P. This elevates the segment-piece 1) on table or wheel l), which in turn throws up the end of lever Q.' This lever is pivoted to the under side of carriage-plate C at q and has a pawl at q', which engages with the ratchet wheel R. This wheel -is mounted in the table or carriage (l by shaft l', which has a pinion R. The pinion engages with a rack-bar R2, secured to one ol' the. tubes A. It will be seen that on the depression of the pawl p the ratchet-wheel ,lt ean turn one tooth, whereupon tlie 'pressure behind piston S will advance the carriage (l a eorrespoinling distance. 'lhese devices insure that the earriage, as a whole, shall be retarded during the movements in and ont ol' the cutter-earrier or ot' that part thereot to whieh the eutters are secu red.

For removing the euttings positively and drawing tliein outward use is made ol" a eliain lr?. ',l`his iina v be actuated in any suitable way. A si'nall rotary air-ei'igine is shown .in Figs. lh to 2o. 0r the motion ol' the reciproca ting part. ean,t hrough the medium ot.' proper converting' meehanism, he used to drive the main.

lt), 'and others. lhe 7 piston E has an arm .13

j pivoted thereto at c is a pinion mountet'l on arm E" by means l l l e u u ol shatt e. lhis pinion engages with the parts F F alternately of a rack, so that as the piston moves out and in there is a continuous rotation in one direction of the pinion. Chain E5 should be rotated directly around the shaft e'; but for the purpose of Aincreasing the speed there is shown a larger Wheel e2 on shaft'e and rotating with wheel e5 is another stud-shaft secured to arm E3 and carrying apinion e3, driven by wheel e?, and e4 is a sprocket-wheel rotated by pinion e3.

To throw the pinion e from 011e rack, F, to the other, F, use is made of a guide-bar ,or plate E2, having a way f f, with a rib f2, between the upper and lower parts and a eamlatch f3. There is a guide-pin e8 on arm E, which travels in the way and alternately lifts and drops the arm E3 and pinion e. Instead of ,this mechanism or of the rotary engine, use may be made of any ol' the mechanisms adapted 4to accomplish the same purpose. By means of the devices above described it will be seen that I produce a mechanism in which all of the movements are eeeted, direetly or indirectly, by the pressure of the air.

The operation will be readily understood. If: it be supposed that the framework has been properly adjusted in position, and that an ap- A erture has been formed in the material sufi iiciently large toiperinit the insertion of the carrier and drills at the end of the wall, (this machine being shown as adapted for long- Wall cutting,) and if it be supposed, further, that the valves j, j', and l are open, it will be seen that the air, passing through pipe I, will, through duct d2, reach the drill-cylinder and cause a rapid reciproeation of the cutter. At the same time the air passes down through pipes L, valve L2, and pipe M to cylinder E behind its piston, and will cause it to advance, as fast as the material is removed in front ot' the cutters. As soon as the forward end of the stroke has been reached the valve m2 will be tripped by the pin a2 and the feed and exhaust in cylinder E reversed, whereupon the cutters and carrier are drawn back. Just as they reaeh the rear position cam N lifts rod l, segment l, and lever Q, thereby releasing pawl Q. The -instant this occurs the pressure ot' the air in cylinderSisallowed to advance the carriage C. Gam N, level' Q, and pawl q are so related that the instant the lever turns the distance or' one tooth the pawl returns andeat-elles the next, thereby stopping the carrier niitil another eut has been made. At t-.he same time guide-pin fn passes to the lower parto of' the way in guideplate O, and the pin n on arm N trips the valve L?, so that the piston is again reversed and another advancing movement begins. Dn ring these motions of the cutter-carrier to a-iid fro the chain E is actuated in one or the other of the ways above referred to or in any suitable manner for withdrawing the euttings. lf at any time the path of the euttcicarrier should beeoine clogged, the valvesjg and J eau be opened, whereupon air will be IIO lconducted throughports g3 g6 with great press- 'ure into the chamber in which the carrier is situated and act to blow out the cutting.

` At g4 there is shown a supporting antifriction-roller which holds the outer end of the cutter-carrier.

The segment-bar p is preferably concentric with the plate C, so that in Whatever position the wheel D stands the engagement with the 1o lever Q will be at the same point on the latter.

By means of the hand-wheel D4, bevel-gear' 1D?, and worm-gear D2 the carrying-table and the cuttings can be thrown into any one of several positions in relationto the main framethat is, can be so arranged that cutters shall be on a line perpendicular thereto, or they may be inclined in front of or in rear of the perpendicular line.

I have above described some of the ways 2o for embodying the several features of my in- Vention;'but I. wish it understood that I do not limit myself to the details shown and described in respect to any one of the particular parts shown, as there can be variation in many Ways without departing from the essential features of invention. It will also y be understood that there are parts mechanically necessary which are not shown in all y the details herein, they being`devices,'such as f 3o braces, used for strengthening and additionally supporting the parts which are parallel.

p Asecond" cylinder similar to that at E can be i employed with its piston-rod connected to the cutter-carrier, which will be found ad-` vantageous in larger machines, as the carrier and the cutters can be thereby steadied and held firmly to their work.

By examining the drawings it will be seen that the picks or cutters proper h are wide 4o enough to produce a kerf of such depth as to freely admit the cutter-engines II H and the carrier G. I am aware of the fact that use has been heretofore made of a rotary plate orv ent cutter-engines on a carrier in a common plane or a straight line in such lmanner that the engines can be causedto advance, together with their carrier, into the kerf produced by the cutters. It will also be seen that cutters and a cutter-carrier of the kindy 6o hereinshown and described can be readily applied also in machines of the kind used for shearing -that is, eecting a vertical kerf or cut along the rib for at the end of the wall in long-wall mining. lWith the construction shown it will be understood that the carriage C or the carriers support D, or both, is provided with slots or openings of such sort as will permit the proper arrange-A ment of the air-pipes andthe parts which proj ect up and down vertically through them; 7c
