1,271,198. Specification of Original application filed November 10, 1896, Serial No I 10, 1811. Ber! To all whom it may concern:

Be it known that I, EDMUND a citizen of the United States, r'esidin icago, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Mining and Loading Machines, of which the following is'a specification.

his application is a division of my application Serial No. 611,603, filed in the United States Patent Oflice November 10, 1896 granted November 3, 1914, No. 1,116,356 and to which application reference may be had for an understanding of the parts not specifically described herein.

More particularly the present invention relates to improvements in machines for scooping and loading materials which are loose or which may be dislodged or loosened.

further object is to provide an improved machine of this character having means whereby the loosened material may be scooped up and delivered to a conveyor to be conveyed away, a further object being the provision of means. whereby the scooping mechanism and the conveying mechanism may be controlled at will.

A further object is to provide an improved machine of this character embodying a scoop having means operating in conjunction tting the material to be ex- C. MORGAN, at

cavated.

A further object is to provide an improved machine of this character which will be siniplc, durable and cheap in construction, and effective and efficient in operation.

To the attainment of these ends and the. accomplislnnent of other new and useful ob jects. as will appear.- the invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed in connection with the accompanying drawings and as more particularly set forth in the claims.

Referring more particularly to the drawings, and in the present exemplification of the invention, the numeral 15 designates generally the frame work upon which the mechanism is mounted and this framework may be of any suitable size and configuration as to properly accommodate the several arts of the apparatus and to permit of the rec and ready operation of the apparatus. framework is preferably made portable by upon suitable traction Wheels 16 as shown more clearly in Fig. 2, whereby the machine may be readily advanced to its work or retracted therefrom and may be transported from one place to another. These traction wheels may be positively proany desired, suitable, or convenient manner or by any'suitably arranged mechanism adapted to such purpose.

Suitably mounted upon the frame work of the machine is a motor 17 arranged and adapted to operate the several mechanisms hereinafter to be referred to and as wlll be more fully described, and this motor may be of any suitable or convenient type of motor adapted to the purposes required. In the form shown and as merely illustrative of an o erative means, the motor comprises an electric motor, the current being su plied thereto through a suitable electric con uctor 18, as will hereinafter be more fully explained.

A gear 19 connected with the motor to be driven thereby is arranged to engage and drive a gear 20 mounted on a shaft 21 preferably arranged to extend transversely across the machine and which has connected therewith for rotation thereby gears 22 (see Figs. 1 and 3) by which, through sprocket or other suitable form of gearing 23, the traction wheels 16 are driven.

Any suitable, well known form or arrangement of clutch 24 may be employed for throwing the driving gear of the traction wheels intoand out of operation at will, and this clutch may be controlled by a suitable operating lever 25, which latter is located so as to be readily accessible, as shown more clearly in Figs. 1 and 3. By suitably actuating or reversing the motor, the traction wheels may be driven in any desired direction to advance the machine to its work or to withdraw the same or to transport the machine from one place to another, and by suitably manipulating the clutch 21 through the medium of the lever 25, the driving gearing of the traction wheels may be thrown into or out of action. It will be understood thatby means of the traction wheels, the machine is only fed up to the work and in the present exemplification of the invention where cutters are shown for cutting the wall of the material, the machine is only fed up to the point where the cutters, hereinafter to be described, are ready to begin to cut the material, for, obviously, the resistance offered to the cutter during the operation thereof on the material would be too great to be overcome by the traction wheels. When this point is reached, therefore, it becomes important and necessary to brace the machine against the resistance offered by the material to be cut, and to provide means for advancing the cutter into the material. In order to accomplish this purpose, there is .mounted upon the frame 15 in any suitable and convenient manner a pair of screw rods 26, one preferably on each side of the machine, and each being pivoted at one end thereof to a pair of arms 27, in toggle joint fashion, each arm being in turn pivotally connected to an anchor shoe 28, the members of each of the shoes 28 being, if desired, suitably serrated on their engaging faces, and respectively arranged to engage the floor and roof of the walls of the room, as clearly shown in Fig. 2. From this construction and arrangement it will be seen that when endwisc pressure is exerted upon the screw rods 26, in a direction away from the point where the cutter is operating, the

toggle arms 27 will be operated to force the anchor shoes 28 away from each other and into engagement with the floor and roof of the room respectively. thereby securing and firmly anchoring the entire machine. If pressure is continued to be exerted longitudinally of the screw rods 26, the machine will be advanced or fed forwardly away from the anchor shoes and in a direction to advance the cutter into the material. In practice, when the anchor shoes are arranged to engage the floor and roof of the room it is preferable to provide two or more of these screw rods and hence, also, two or more pairs of toggle arms 27, and shoes 28 for the reason that by suitably arranging one pair of these anchoring and feeding devices on each side of the machine and another pair on the opposite side, as cleai'ly indicated in Fig. 1, it is possible to straighten the machine in case its feed departs from a straight line. This may be easily accoin plished by throwing the one or the other of the anchoring and feeding devices into or out of action, as occasion may require. Any suitable mechanism may be provided for exerting the pressure above mentioned longitudinally upon the screw rods 26 whereby the machine is first anchored and then fed forwardly to advance the cutter to its work. A simple and eflicient means for accomplishing this result will now be described, and comprises a gear 29 arranged to be driven from the motor 17 and to engage and drive a train of gears 30, 31. The gear is mounted to rotate with and adapted to drive a shaft 32 suitably mounted in the frame of the machine. A shaft 33 is suitably mounted in the frame of the machine to extend transversely thereacross and carries a gear 34, arranged to engage a suitable gear 35 on the shaft 32.

An internal screw threaded sleeve or out 36 (shown more clearly in Fig. 2) is mounted on each of the screw rods 26. By rotating said nuts or sleeves in one direction or the other, the desired pressure is exerted upon the screw rods 26 in cm direction or the other to effect an anchoring of the machine and the feed thereof, or else. to effect a release of the machine. As the arrangement of the gearing for rotating these nuts is the same for all of the screw rods 26, a specific description of the arrangement and operation of one will apply equally as well to them all. The nut 36 carries or has formed integrally therewith two gears 37, 38. Upon a suitably and conveniently mounted short or stub shaft 39 (see Fig. 1), two gears 40, 41, are mounted said gear 41 being preferably of a relatively large diameter and meshes directly with the gear 38 of the nut while the gear 40 is of relatively small diameter and engages and drives the gear 37 through an intermediate idler gear 42. From this construction it will be manifest that when the gear 41 is idle and the gear 40 actmg, the sleeve 36 will be slowly rotated in one direction, that is, 'n a direction to effect a longitudinal pressure on the screw rod 26 in a direction to cause the anchor shoes 28 a such relation that the actna ting lhe chine forwardly, and the gear 41 acting, said sleeve 36 will be rapidly revolved in the opposite direction, and an endwise movement of the screw rod 26 in the opposite direction will be effected,

thereby releasin the anchor shoes 28. Any suitable or well known form of clutch 43 see Figs. 1 and 2) maybe employed to t row either gear 40, 41, into or out ,of action at will. A gear 44 mounted on shaft 39 is arranged to engage a gear 45 on the shaft 33, whereby the train of gearing above referred to may be driven. By means of a suitably and conveniently arranged clutch 46 the mechanism for actuating the anchoring and feeding mechanism on one side or the other of the machine may be thrown into or out of action at will. From the foregoing description it will be manifest that whenthe cutter is advanced to the limit of the screw rods 26 by suitably manipulating the clutch 43, the screws may be moved in the opposite direction to advance the anchoring shoes to a point closer to the machine, thereby affording a fresh grip,.when the feeding action may be repeated.

The cutting mechanism and themeans for same, according to this exemplification of the invention, will now be described. In practice it has been found desirablc to use the ordlnary sprocket chain cutters. Upon the front end of the framework 1:3 there is mounted a cutter frame designated generally by the reference numeral 47 (see particularly Figs. 2 and 8)., in chain cutter 48 (see also Fig. i) mounted to operate thereon will operate in a horizontal plane to under-cut the wall of the material or to out what might be termed the floor kerf as clearly indicated in the figures referred to. The cutter frame 47 may be supported in any suitable. manner, preferably by means of the bottom of the supporting frame 15, and any of the usual, well. known types of sprocket chain cutters employed in the art may be used. This chain cutter 48 is preferably actuated from the shaft 32 through the medium of a gear 49 mounted on said shaft (see particularly Fig. 2) to engage and drive a gear 50 mounted on ah upright shaft 51, which latter is suitably mounted in the frame work and carries a sprocket gear 52 arranged to engage and drive the chain cutter 48. The shaft 51 may be thrown into or out of operation at will by means of any suitable. convenient, or well known form of clutch 53 carried by the shaft 32. The horizontal cutters 48 are preferably arranged to cut a kerf extending substantially the entire width of the room so that asthe machine advances fartherand farther into the vein or wall of the material, the cutter cuts all the way across to form the floor for the room. In order to cut the side Walls of the room at the same time and while if the gear 40 is idle in order to facilitate the breaking down of the material, thereby after breaking down the material leaving the side walls smooth and regular to permit the machine to advance, side cutters 54, 55, are provided and arranged to operate in upright planes, and a suitable frame 56 the side cutters operate. These slde cutters may be actuated preferably by means of a short horizontalshaft 57 (see Fig. 1) which carries a suitable sprocket at the outer end thereof over which the side cutter chain 54 runs and at the inner endof said shaft is a gear 58 arranged to engage a gear 59 carried by the shaft 51 (see Fig. 2). From this construction it will be manifest that when the shaft 51 is rotated the side cutter 54 will also be actuated. A similar arrangement is provided on the opposite side of the machine for actuating the side cutter 55, except that in this instance the upright shaft 60 corresponding with the shaft 51 is rotated by the movement of the horizontal chain ciltter 48, said chaincutter engaging a sprocket gear on the upright shaft 60. and thereby rotating said shaft, and hence, through the engagen'ient of the gears 61. c2, effecting a rotation of a short horizontal shaft 63. corresponding to the shaft 57. and which carries a sprocket chain over which the side cutter 55 passes. In order to withdraw the cutters from the kerf in which they are operating, that is. when it is desirable or necessary, for instance, to withdraw the entire machine from the room in which it is operating, and also, for the purpose of facilitating the transportation of the machine from place-to place or point to point. it is dcsirable to make provision for so collapsing the cutters thatundne friction against the walls of the kerf in case of the horizontalputter, or of the walls of the kcrf and rooni in the case 8 the side cutters. will not be opposed to the ready or easy witlulrawal oi the machine. In order to accomplish this. the frames 47 and 56 upon which the cutters op erate are constructed in sections, the adjacent scctions being secured together by suitable fastening devices adapted to be readily removed to permit removal of the frame secder to effect a breaking down of the under cut body of the. material. This necessitated an arresting of the action of the machine for a considerable time to withdraw it and again advance it to the work. In the present invention there is provided meunswhereby the withdrawal of the machine is unnecessary during the breaking down operation, which will now be described.

is provided upon which Journaled in the framework of the machine is a shaft 64 arranged to extend transvers'ely across the machine, which shaft carries a gear 65 arranged to mesh with and be driven from a gear 66 (see Fig. 1) carried by the shaft 51, and by means of which r07 tation is imparted to the shaft 64. By means of any ordinary and well known form of clutch 67, the rotation of the shaft 64 may be arrested or effected at will. A shield 68 preferably extending cnt'irely across the machine is journaled to swing upon the shaft 64 (see also Figx2) and carries depending arms 69 in which are mounted short shafts carrying at one end a socket 70 and at the other end a ear 71 arranged to be engaged and driven y a gear 72 mounted on the shaft 64. From this construction it will be manifest that the shield 68 may swing about the shaft 64 and the mesh of the gears 71. 72 will always be maintained. A suitable and convenient form of tool 73 is provided for formin holes or incisions in the wall of the material above the under-cut. The shanks of the tools are arranged to be detachably secured in the sockets 70 in any suitable manner. lVith this arrangement, when the machine is advanced to its work, the tools 73 operate to form openings or incisions for receiving breaking down means to dislodge particles of the wall at the same time that the side and under-cuts are made. When a sufficient depth of out has been made and it is desired to break down the body of the under-cut coal, the tools 73 are released with respect to the sockets and removed therefrom so that thcy may be withdrawn by hand without withdrawing the entire machine and when thus withdrawn the breaking down means may operate in these holes or incisions. The shield 68 may be swung about its pivot until the fare of the shield is presented toward the holes or incisions formed by the tools 73, so that the driving or operating mechanism of the tools may be protected. Thus it will be apparent that the breaking down will be effected with out the loss of time incident to the withdrawal of the entire machine as the tools 73 may be readily detached.

In the operation of machines of this charactor and especially mining n'iachines, as heretofore carried out and wherein provi' sion has not been made for automatically removing the material when broken down. operators remove the broken down material which has fallen upon the floor, either by hand or else manually by shovels before the machine can again be advanced to its work. This has always consumed valuable time, which might otherwise be employed in effecting another cut preparatory to breaking down more material. It is one of the ob ects of the present Invention to provide means whereby this time may be saved and wherein instead of removing the broken down material by hand, this work may be accomplished without in the least interfer= ing with the continuous action of the machine in making the next cut. A simple and efficient means for accomplishing these ends and objects will now be described.

-Llhe frame 47 upon which the cutter 48 operates, is arranged in the form of a plat form, as clearly indicated in the drawings, and receives the material which is-detached or broken down. As this platform is can ried by the machine it will be readily seen that no obstruction is offered impeding the progress of the machine as it is advanced to the next cut. The detached particles falling 11 on the platform 47 may lac-removed there rom in the following manner: Mounted upon the frame 15 is a supplemental or carrier frame 74 which, for the sake of convenience. will be hereinafter designated as a jib, reference being had more particularly to Figs. 1, 2 and 3. Suitably mounted on the jib 74 at the front end thereof, is a scoop or shovel 75 having the toe or forward end thereof presented forwardly and arranged to gather or scoo up the material from the platform 47 an remove the same. This scoop or shovel may be operated in any suitable manner, but a simple and eflicient means for accomplishing this end will now be described. In the form shown the scoop or shovel 75 is pivotally mounted on horizontal gudgeons or pintles or the like, as indicated at 76 whereby the said scoop may be 100 rocked about a horizontal axis as indicated in dotted lines in Fig. 2,.-to dump the material out of the rear end thereof after it has been scooped up thereby. The scoop shovel may be tilted in any suitable manner, preferably by means of gearing which Will now be described, particular reference being had to l igs. 1. and 3.

One of the gears of the train of gears 30 is mounted on a shaft 77 suitably jour- 11o naled in the frame work. This shaft 77 is preferably a short shaft and is flexibly connected in any ordinary and well known manner with a hollow shaft 78 as indicated at 79 and is provided with suitable bearings 80, preferably secured to the trough or way 81. The liexible connection 79 permits the jib to turn about its upright axis 82, as willbe hereinafter set forth. Arrangcd within the hollow shaft. 78 to slide longitudinally axle or pivot 76 of the shovel or scoop 75 so that when one or the other of the gears 84, 85, is clutched to rotate with the shaft 83, the scoop or shovel will be tilted or swung about its pivot or axle to elevate the forward end thereof.

It is also necessary that the scoop or shovel be advanced and retracted independently of the machine in order that the detached or broken down material may be scooped up. A simple and eflieient means for effecting this movement of the scoop or shovel will now be described. The pintles 76 upon which the scoop or shovel is mounted andwhich form its axis, are mounted in a forked frame comprising arms 88, mounted to slide longitudinally in housings or guides 89. The, arms of this frame are provided with rack teeth as clearly indicated in Fig. 2 with which gears 90 mounted on a shaft 91 mesh, and this shaft 91 is journaled in suitable supports upon the jib "[4. Thus when the shaft 91 is rotated in one direction or the other, the arms 88 or forked support of the scoop may be moved forwardly and backwardly, iongitudinally carrying with them the scoop 75, and hence it will be seen that the scoop will be advantrd to scoop up the material from the platform 47 and then withdrawnto the point where the dumping 15 to be made. The longitudinal movement of the shaft 83 with respect to the hollow shaft 78 permits the gearing for tilting the scoop to remain in mesh during such movements of the scoop. as will be readily understood. The rotation of the shaft 91 in either direction may be effected in any suitable manner, and at will; and for this purpose the hollow shaft 78 may be provided with a gear 92 arranged to engage and drive a companion gear 93, mounted upon a shaft 94, journaled upon the jib 74. Loosely mounted on the shaft 94 are oppositely arranged bevel gears 95, 96, and a clutch 97 of any ordinary and well known construction may be employed for locking eitherof the gears 95, 96, for rotation with the shaft 94. A bevel gear 98 is mounted on the shaft 91 and is arranged to intermesh with the gears 95, 96. Thus it will be manifest that the shaft 91 may be revolved in either direction at will to advance the shovel to scoop up the material or retract it after the material is scooped up, to the point where the dumping is to be made.

It is also desirable that the scoop shall be mounted so as to move transversely across the machine in order that the entire width of the room or a considerable area may be conunanded thereby, to the end that all of the material may be scooped up and loaded into the vehicle or receptacle. For this purpose. the scoop may be mounted in any desired or suitable manner but preferably the 'jib 74 is mounted to swing upon the upright pivot 82 already described. A bearing 99 (see Figs. 1 and 2) is carried by the jib and is arran ed to enga e a bearing flange 100 carried y the main rame, whereby the thrust of the scoop or shovel advancing mechanism is resisted. and the jib is guided in its swinging movement. For the same purpose a bearing 101 is provided upon the main frame upon which the forward end of the jib bears, in order" to steady and guide the latter in its movements. If desired and as shown the bearings 99, 101, may be anti-friction rolls in order to reduce friction. The swinging movement of the jib about its upright pivot 82 may be effected in any desired or suitable manner, and a simple and eflicient means for accomplishing this result will now be described, reference being had particularly to Figs. 1 and 3. H

at segment rack bar 102, suitably mount ed upon the jib T1 is arranged to be engaged by a gear 103, which latter is also provided with gear teeth so positioned that they will intermesh with operating gears 104, 105, loosely mounted on the shaft 94. Any ordinary, suitable form of clutch 106 is provided for coupling either of the gears 10-1, 10.5 to the shaft 94, whereby the gear 103 may be rotated in either direction at will, and hence the jib 74 may be swung or moved in either direction at will, thereby enabling the shovel or scoop 75 to command the on tire or any portion of the area of the room. In order to obtain the highest degree of eliicieney and speed in operating this machine, it is important that the work of loading the material into the receptacles or vehicles to carry it away, be carried on con-' currently and simultaneously with the operation of the machine. In the arrangement, as above described, this can be most conveniently and expeditiously effected by arranging the shovel or scoop to deliver the material therefrom into the receptacle or vehicle. To this end, therefore, there is provided upon the jib 74 the trough or way 81 which is upwardly inclined from the forward end thereof, said forward end being so relatively arranged with respect to the scoop or shovel 75, that when the forward end of the latter is elevated or tilted as above described, the material will 'run by gravity from the scoop or shovel onto a coriveyer 107, which latter is preferably of the endless type (see particularly Fig. 2). The other end of the trough or way 81 and the respective end of the conveyer 107 are arranged in suitable positions to deliver into a car 108 the material which is deposited upon the conveyor 107 from the shovel or scoop 75. This endless convcyer 107 is 0per atcd, in the present form of the invention by means of a shaft 109 arranged preferably at the lower end thereof and a shaft 110 is arranged at the other end of the conveyer over which the latter passes. The shaft 109 is rotated through the medium of a gear 111 thereon (reference being now had more particularly to Fig. 3). which meshes with a gear 112 on a shaft 113, the latter being mounted upon the jib and is arranged to receive rotation through the engagement of a gear 114 secured for rotation with the gear 112 and which gear 114 meshes with a gear 115 on the shaft 94.. A suitable or any ordinary form of clutch 116 may be employed to lock or unlock the gear 115 with respect to the shaft 94, whereby the actuation of the conveyer 107 may be started or arrested at will.

In Figs. 6 and 7 there is shown a modified form and arrangement for effecting a loading of the material from the scoop or shovel to the receptacle which conveys away the material. In this form the trough or way 117 is arranged horizontally and the S000 or shovel 118 is arranged to slide longitudinally with respect to the trough or way 117 and the trough or way is adapted to swing about the upright pivot 119. The car or receptacle 120 is arranged at the end of the trough or way 117 so as to receive the material discharged from the latter. A rack bar 121 is mounted upon the jib preferably some'distance above the bottom of the trough or way 117 and pivotally mounted at the forward end of the rack bar 121 is an ejector 122. The scoop or shovel 118 in this form of the invention .is pivotally connected as at 123 to the arms 121which latter are preferably arranged below and spaced from the rack bar 121 and are provided with rack teeth 120' on the upper faces thereof. A shaft 126 corresponding with the shaft 91 is mounted upon the ib and receives its motion similar to the manner in which the shaft 91 is rotated. The gears 127 are provided on the shaft 126 which engages the rack teeth 125 and serves as a means for moving the arms 124 forwardly and rearwardly to correspondingly advance or retract the scoop or shovel 118. Another gear 128 is provided on the shaft 126 and this gear 128 meshes with the teeth on the rack bar 121, the latter being preferably arranged intermediately of arms 124. Thus it will be manifest that when the shaft is rotated the scoop or shovel 118 will not only be moved for wardly or backwarolly but the rack bar 121 will also be moved in a direction opposed to the direction of movement of the scoop or shovel to correspondingly move the ejector 122, which latter removes th material from the scoop or shovel into the trough or way 117.

Any suitable convenient arrangement of gearing for positively swinging the ejector 122 at will may be provided but as the invention does not reside in the specific form and arrangement of such caring, it is thought that illustration of suc gearing is not necessary. In this form of arrangement when the scoop or shovel 118 has been advanced to scoop up a load of the material. from the platform 47 and has been retracted to the point shown in full lines in Fig. 7, the ejector 122 will then be lowered to the position shown in full lines in said figure and the gears 127 will then be actuated to ad- Vance the S000 or shovel to scoop up another load 0 material. Simultaneously With such movement the rack bar 121 will be moved in the opposite direction and will force the material backwardly into the trough or way 117. This ejector 122 not only prevents the material from being advanced with the scoop or shovel by acting as a stop or scraper, but also sweeps the material rearwardl through the trough or way 117 and into t e car or receptacle 120. In this form of the invention the S000 is open-ended and the material is loaded into the car or receptacle 120 through one side of the latter as clearly indicated. This form of arrangement is particularly well adapted for operation in mines and especially in thin or shallow veins of material or coal Where a particularly low framework is necessary.

In the form of machine where the undercut or kerf is made with a chain cutter, itis desirable to snub or cut off or break down the lower corner of the under-cut material, in order that when breaking down mechanism actuates in the holes or incisions-made above the under-cut, the material will have sufiicient room to fall and properly dis integrate. Heretofore this last operation has een performed by hand. In such case it was necessary to first withdraw the machine from thematerial it was operating upon in order to give proper access to the wall of the material. In the present invention there is provided means whereby this snubbing, cutting off, or breakin down of the material may be accomplis ed automatically and during the operation of the apparatus. A suitable and eflicient mechanism for accomplishing this end will now be described, and preferably comprises one or more cutters 129 adapted to be detachably bolted or fastened to-the scoop or shovel 75 so as to be projected beyond the forward" edge thereof. At the proper time of such operation upon the wall of the material, the cutters 129 may be adjusted in position upon the scoop or shovel to project forwardly therefrom. The scoop or shovel is then advanced in the manner as has already been set forth and this cutting, snubbing or breakin down is effected in the manner as clearly indicated in Fig. 8 of the drawings and without withdrawing the machine from the material. After this cuttin operation, the scoop or shovel may be with rawn in the manner as already set forth and the cutters 129 unfastened and adjusted into inoperating ositions preferably back into the floor of t e scoop or shovel, as clearly indicated in Fig. 3. It will be understood that this cutting with the cutters 129 requires the expenditure of but a small amount of power and can be readily and easily applied through the scoop or shovel advancing means.

In the event that an electric motor 17 is employed for operating the several parts of the machine, as above described, it is necessary to supply the operating current thereto in a manner that will ermit of the advancement of the machine arther and farther toward the work as the material is broken down, and a simple and efiicient means for accomplishing this result comprises the conductor 118 which leads from the motor17 (see particularly Fig. 2) to a reel 130 suitably mounted to rotate upon the main frame. A flexible conductor 131 is arranged to be wound upon the reel 132 or to be unwound therefrom as the case mav be, and electrical connection, in any suita le or well known manner as will be fully understood by persons skilled in the art, may be made from the conductor 131 to the reel 130, and from said reel to the conductor 18, whereby current may be supplied to the motor 17. Obviously, the conductors 131 and 18 are of the ordinary type of insulated conductors, whereby short circuiting is prevented. By providing means for winding or unwinding the conductor nously with the advancing or retracting movements of the machine, the current is supplied to the motor for actuating the several parts of the apparatus as above. ex

lained. The reel 130 may be conveniently rotated in the followin manner: A gear 132 mounted on the axle of the reel 130 engages and is driven by a worm 133 mounted on the shaft 32. From this construction and arrangement it will be manifest that when the motor 17 is actuated in one direction or the other, the conductor 131 will be correspondingly reeled up or paid out.

In order to carry out the general system of conveying away the material, it is desirable to provide means for the automatic withdrawal of the loaded cars or vehicles 108 and the co-incident advancement of empty cars from and to the point where the material is delivered by the delivery device above described. A simple and eiiicient means for accomplishing this result comprises tracks 134 upon which the cars 108 run. The tracks are shown as arranged similar to a turn out in a street car line upon one branch of which the empty cars are run 131 from the reel 130 synchroand upon anotherpart of which" the loaded. understood that inthe.

the cars are removed as fast as they are loaded so that they may be temporarily moved to one side of the switch or turn-out and ran-empty car advanced to take its place will now be escribed, and comprises an endless belt or cable 135 suitably mounted'upon guide pulleys 136, 137, 138, 139, conveniently arranged, and these cars are adapted to be attached to the runs of the cable by means of fastening devices104 connected with the cars and which fastening detached when desired. The endless cable is iven motion in an suitable manner, pre erably from the 111 ey'139 on the shaft of which is secured a gear 141 which latter is adapted to be engaged by a gear 142 driven through suitable gearing 143 from the axle of the motor 17, and a clutch 144 may be employed for controlling the rotation of the shaft on which the gear 142 is mounted.

The present divisional application contemplates the omission of the cutting apparatus and also ofthe platform 47 and the drilling mechanism so that the machine shown in the drawings can be used purely as a loading machine in a narrow entry for operation at the base of the mine wall in a low ,roof mine chamber. The fact that the scoop has a rear end portion approximately of the same width as the endless belt conveyer and is in direct alinement therewith and can reach out in front of the conveyer enables the width of the machine to be greatly reduced. It should also be observed that the motor may be placed on the main frame beneath the conve er so as to maintain a narrow machine w en used as a loader only. J

The jib frame is mounted on an upright axis 82 which is preferably nearer the delivery end of the conveyer than the receiving end so that the scoop may move through relatively larger arcs than the delivery end of the conveyer. This arrangement will maintain the delivery end of the conveyer over the mine car for various arcuate positions of the scoop.

The wheeled truck comprises the Wheels 16 and the main frame, and the propelling mechanism for this truck comprises the shaft 21 and the sprocket chains 23 and the worm gearing therefor may be such as to move the loader forward or rearward at any desired speed. The gearing may be devices may be readily the loaded cars. Automatic means whereby such as to more the scoop forward slowly but if the scoop meets with two much resistance there may be slipping of the wheels on the track and therefore in some instances it may be desirable to move the loader forwardly even more slowly and more powerfully by means of the spaced apart screwthreaded rods anchored in the mine chamher close to the sides of the jib frame but allowing suflicient room for the latter to swing over its arcuate paths of travel.

An important feature of my invention is the provision of a pivoted rear portion of the scoop and approximately horizontal re ciprocation of the pivoted rear portion of the scoop. In the present instance this is secured by securing the scoop to a supporting shaft or trunnions 76 which are pivoted in the slide blocks 88 and which in turn are confined to approximately horizontal guideways in the jib frame. The operating mechanism may therefore be such that the rear portion of the scoop itself may be reciprocated in a general horizontal direction while the forward portion is given turning movements to cause the material gathered b 1 the scoop to slide to the rear portion of the scoop and finally out of such rear portion backwardly onto the endless belt conveyer.

It should also be understood that the de' tachable platform 47 may be secured to the main frame without the use of any of the cutting apparatus. A metal platform is thus employed instead of using the floor of the mine chamber as a platform. However the apparatus still remains a loading machine.

Obviously those skilled in the art may make various changes in the details .and arrangement of parts without departing from the spirit and the scope of my invention as defined by the claims hereto appended, and I wish, therefore, not to be restricted to the precise construction herein disclosed.

Near thelower end of the endless conveyer may be located the cross piece inclined downwardl and rearwardly toward the upper sur ace of the endless conveyer 'so that said cross piece may cooperate with the spacedapart side pzztes to act as a chute to direct material from the rear end of the scoop onto the said conveyer, and said cross piece may also act to prevent the material discharged from the scoop from falling off the conveyor. The conveyer is continuously operated so as to be capable of conveying the discharged material to the mine car as soon as such material is received by the conveyer.
