MINING AND CONVEYING MACHINE.

Application filed June S, 1919', Serial No. 302,9?!9. Renewed January 12, 1927.

The invention relates to mining machines, and more,particularly to mining machines adapted to undercut the coal and to convey away the coal after it is dislodged or broken away from the seam.`

Objects and advantages of the invention will be set forth in part hereinafter, and in part will be obvious herefrom, or may be learned through practice with the invention; these objects and advantages being attained and realized through the means, instrumentalities, and combinations pointed out in t-he appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations andv improvements herein shown and described.

The accompanying drawings, referredV to herein and constituting a parthereof, illustrate one embodiment of the invention, and together with the description, serve to eX- plain the principlesof the invention.

- F ig. 9 is a diagiaminatie elevation showing the machine in use in entry work; A

machine emywhichV has been lpreviously undercut.

Fig. 10 is a diagrammatic plan showing the machine used in room` work; 1 yFig. 11 is a diagrammatic plan showing the machine used in narrow work, such as entry work;

Fig. 12 is a fragmentary, sectional figure, corresponding to the centralpart of Fig. 4'; and I i Fig. 13 isa detail View of thegearing connection between gear12 and gear 13.

rl`he invention provides a novel and useful machine adapted to make an undercut-l ting, the machine sliding into the undercntting as it is made', and carrying into the tindex-cutting conveying means adapted to underlie the greater part ofthe undercut coal. The undercut coal may then be broken down or suitably dislodged, as desired, subsequently tothe completion of V,the undercutting and, falling upon the conveyor, is delivered outside of the machine.

The machine operating in this manner leaves .it free, or as a matter of choice, to the workman as to the rselection ofthe best means for breakingfdown the coal. .In certain kinds of coal it is a great advantage both in speed ofworking and in` the quality or size of the coal mined to simultaneously break down ak relatively large mass of coal The machine will also operate, where the nature of the coal admits, to break down the coal gradually or piecemeal as the undercntting proceeds, or to permit the coal to sohreak of itself, when it will do so, in any case conveying away the dislodged coal rllhe machine is also vprovided with two cutting fronts, preferably at right angles to each other, and can travel and cut in two or more directions, that is, it will advance perpendicularly into the face of the coal and then along the face fory an indefinite distance, the conveying means being capacitated to convey away the coal in either case.

The machine is of very low or flat con-i struct-ion whereby it can operate in very thin veins or seams and will in all practicable seams have sufficient head room over the machine for its easy and convenient at tendanceand controlby the workman.

wheel is loose on the shaft 14. Fixed tothe hub of geanwheel 13 is one member-44 of a clutch, the other member elcf the clutch being splined andlongitudinally slid'able on shaft 14 in the usual manner. This clutchV simultaneously throws 'in or out vboth the sprocket wheels 4f and 5, each sprocket wheel having' a friction or slip `drive between it andthe clutch,4 as already described. By

'throwing' the clutch 411, L1:5 in or out, the

nient jacks 4G kand 47 aie fastened inV vappropriate locations at the face of the work, and

vthe cables 48 and 49 are made fast thereto and are wound upon drums mounted upon and driven by the machine. y'

In the present machine, the drums 50 and 51 are driven from the motor Ll0, which also drives the cutter chain. A shaft 52 is journaled in bearings 53 and 541 on the machine frame, and fixed on this shaft 52 is a/gear vwheel :35, which gear wheel meshes with the gear wheel l-l on shaft 14. The two winding drums 50 and 51 are fixed to shaft 52 at either end` thereof, and the cables from the j aclzs #t6 and elfi'k are wound upon these drums, respectively. The machine is preferably mounted on a plurality of shoe plates 56, the bottoms of which are round so that the maycl'iine'willy slide readily over the bottoni in any direction. y y

. uiding' pulleys 57 and 58 are mounted on the machine.frame at suitable points, for directing the pull of the cables on the machine.

As shown in Fie'. 11.r they are arranged to move the machine forwardly, as in entry work or othernarrow work. rPhey may be till arranged, ifV desired, to drive or advance the .machine .sidewise` as might be required at times in 'breast or room work, or in long;` wall work, or the like. 71th this mechaiiism constructed and arranged as described,

the cutter chain and the advancing means for the machine areoperated'together and simul- Vtaneonsly. from tl'i'erommon motor. Itwill he noticed that the winding;` drums 5l) and 51 andthe pulley 57 are mounted on .the rear raised portion ,of the frame at asubstantial elevation above the vpulley 58, which as shown in- Fig. 1. is inountedvonV the lower portion ol" the side of the frame which the korf cutter runs; sorthat thecable 49 will be raised substantially above the level Y of the conveyor 86. In soineinstances, where it is necessary to give an increased clearance .ofthis cable 49 above the conveyor 86,. the pulley 58 will project substantially above the top of the frame '1 in which it is mounted. It will.beunderstood, of couise, that these pulleys are replaceable and may be positionedwherever there is a corresponding socket in the frame. Gear wheel 55 is preferably inclosed in ai housing- G0, which -is formed in the top 6l o-f the casing, inclosing the motor, the

sprocket wheels and other driving parts. z All the operating' mechanism is inclosed in a casingl 62 to protect 'itfrom loose coal, and also from the dust so far as possible. rIhe easing` is formed by the top plate G1 fitting onthe top edges of the frame, bythe side frames and by a vertical vall 63 between the driving' mechanism and the conveyor.

In the embodied form, a transversely arranged. conveyor is arranged at the inside or toward the front of the machine, and in front ofthe motor and driving' mechanism already described, upon `which conveyor' the dislodged coal. falls and whereby it is' passed across ink front of the driving mechanism and then, by. cooperating 'conveying means,

alongside of the driving'mechanism to the rear and to any desired or suitable loading mechanism or devices. l

In such embodied mechanism, an endles conveyor (5 8 rims over an idle roller 69, located at theinner end of the conveyor and `iournaled in the rmachine frame. In the multiple unit or sectional machine, this conveyor extends entirelyacioss its section and discharges on to the longitudinal conveyor located in the other unit or section. At its 'opposite end conveyor G8 passes overa drivingroller 70. This roller is preferably drivenfrom' the common motor Llt).

In the present embodied form, the. shaft 71 of this roller is'journaled inthe machine frame. and is driven through pinions 82 and 83, and shaft T7 from a friction or slip drive 72- having' a pressure spring-73, and a clutch T4: is provided for throwing the conveyor in or out. Shaft T7 is provided withv suitable bearings 75 and 7G. One dise memberv of friction vdrive 72 is splined on a shaft 77, and another disc of '74 is fast on a sleeve 78,'which sleeve is loosely mounted on shaft Gnemeinber of clutch 74 is splined to slide on sleeve 78, and the other clutchmeiiiber is fast on a bevel gear wheel SO', mounted loose on sleeve 78. rEhe-'bevel gear 8O meshes with. a bevel pinion 81 on the shaft of the motor 40. y

r`As embodied, in the other section of the machine is mounted what may be 'termed lthe longitudinal. conveyor, which conveys the dislodged ycoal to the rear, as already indicated, This conveyor 86 at its inner end runs over an idler roller 8". which is jour naled inthe machine frame, and at` its outer end the conveyor runslfover'a driving roller ltlll iis i r la fill fill

running respectively 88, which is journnled in the machine tranne.

The shaft S9 of this driven roller has n squared end 90, extending from the trarne plete 853 like the head Bel. This squared heed lits into n socket in shaflit 0l which is journnled in tranne plete llo. lVhen the t\vo main trame .sections are tilted together, the Ahulls will couple us shown in Fig. l. Shni't 01 luis prelierublvf :i friction or slip drive 92 :1nd is provided with u bearing' 94. Fixed to one part oli this shaft 91 is n gear wheel 05, which is driven by :t pinion 9G mounted on :1 shaft 0T jourrnilcd in bein-ings 0S and 00. `Pinion 0o and shutt 0T are provided with a clutch 100 which connects und disconnects the pinion und shaft. Shaft 9T is shown :is n continuation ot the shatt ot the common motor 4 0, which in this embodiment drives the entire machine. In this sectionfolV the machine also, :i casing 10i is provided over the driving` mechanism, with n vertical wall .i012 closing it oll troni the conveyor (Fig, 5).

Suitable operating levers 103, aL und 105 zireprovided for the clutches 45, 74 and 100, resl'iectively, which levers project exteriorly 'from the casing to provide lior the control ol' the clutches during the operation oit the machine. The levers are pivoted on the uniehine 'tranne :ind have yolied endsl etrmldling the slidnble clutch members in the nsunl man4 ner, but` ure omitted 'from the drawing for eleurness of showing ln Fig. 5 a bridge plete 10G"L is shown, upon which the coal is pushed trom the conveyor over the top of the casing. This plete, i100 is anchored to the easing by bolts 100, :ind extends at its front edge :aibstnntinlly to the conveyor 8G, to better enable the plate to scrape the coul from the conveyor the only el-'sentiel thing that the plate should come down nee r the conveyor in or der to remove the ccnl tlierelirom. ln Fig. 8 nu endless conveyor 100 is shown receiving the coed troni the conveyor and adapted to traneport or convey it to cnrs or other receiving devices in the rear.

ln Fig. 0 the mnehiue is ehon'n in use in entry Vivorh in u thin con] seam, the bottom being shot up or exeavutedto give the requisite height or heed room. The con- `veyor is shown discharging into n car l 0T standing on the track.

ln Fig. l0 means lire shown somewhat dingrannnntically, in plan. 4For progressing the machine laterally or sidewise, during the undereutting ol`: the senin. The cnbles i8 :ind 49 'from drinne; 50 and 5l.. are shown over pulleys .10B und '100, the cables being- :nichored to jacks L10 und lll. lf desired. :i fixed beurer cable or rnil 112, running through rings or pulleys on the 'traine` muy he used to hold the nnichine laterally in line. In Fig. l0, the

i pulley 58 has been detached from its socket,

and the pulley 10S has been positioned so that the crible t9 passes from the pulley 57 which is .in a` raised elevation, downwardly to the pulley 10S und thenceto the jack 110. As hereinbefore stated, this pulley 108, if

desired, muy project nl'nvnrdly a slight distance above the level of `the frame l so as to give additional clearance to permit the coul to pass on the conveyor beneath the cable 49.

Plates 113 are employed to direct the coal on to the conveyors, und horizontally disposed supporting plates 114i are pre terribly locuted closely beneath the top reaches of the conveyors respectively, und are fixed to und supported by theunichine traine. Theee plates enable the conveyors to receive the impact ol the dislodged and falling coal Without dislocrition, deformation, or other dani-age, although the impact is not severe or serions in relatively thin seams.

A bridge. plate 'll carries the traveling coal from the transverse conveyor G8 on to the longitudinal conveyor 86, This bridge. plete preferably provided with menus 'lor assisting in holding the machine sections together, und the embodied form of lsuch holding menus comprises pins llo fixed to the bottom of the bridge plate, Iand lit ting into holen :l r1ned in the top ot the abutting reaches E3 and 3G o'l the frames ot' the sections.

.-"vdditioiml meanfe 't'or holding the sections together are shown :is eonnin'ising a, latch lli", pivoted on one section of the tranne, nud taking ove f a. lng 1.18 on the other section of the iframe 1, :i pin 1.15) fitting into n hole in the frame to loel: the holding means in engagement.

rl`he manner of operation olf' the nnichine will be understood 'from the descriptions given in connection with thevarioue devices :1nd mechanisms. Asprevionerly pointed out, the machine can renmin continuously at the face ot the work, the undercut coal being` shot down or otherwise dislodged on to the conveyors. sind is at once conveyed acrossv und buck ilrom the mnel'iine into the curs or other receivingmenns, :uid all moving ot machines sind subetitution ot one Inn-- chine for another is avoided. This is the ease whether the innehine be employed in entry dri ving or other narrow Work, or in room n'orh' or other A'wide work.
