Patented July 25, 1922.

Application filed June 27, 1910, Serial No. 569,168. Renewed January 7, 1918. Serial No. 210,796.

T 0 all whom it may concern Be it known that I, EDM ND G. MoRoAN, a citizen of the United States, residing at Morgan Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Mining Machines, of which the following is a specification.

This invention relates more especially to that type of mining machines which are drawn along the wall of a drift or tunnel while they are being continuously operated.

The main general object of this invention is to provide an improved construction, combination and arrangement of parts according to which a. machine of this character can be simply and durahly constructed and made rapid and eflicient in action.

The primary object is to provide an improved cooperating arrangement between the cutting, breaking down and removing mechanisms.

Another object is to provide improved automatic meanstor breaking down the coal during the progress of the cutting operation.

lVlcre particularly it isthe object of the present invention to provide mechanism for cutting a plurality oi -spacedsa-part horizon tal kerirs and a vertical lrerf spaced back from the face ofthe mine wall to effect the cutting of columns or cores of coal in position to he acted upon by a plurality of superposed pick machines to break down the coal into the range ot operation of the conveyer which is provided with a scooping, receiving end adapted to travel in the plane of the lowermost horizontal lrert. i

Other and further objects will appear in the specificationand be specifically pointed out in the appended claims, reference being had to the accompanying drawings exemplifying the invention, and in which- Figure 1 is a general plan view of a mining machine constructed in accordance with the principles of this invention.

Fig. 12 is a detail plan view of the rear portion ofthe machine, partly in cross section; i

Fig. 13 is an end view in cross section on the line 13-13 of Fig. 12.

Referring more especially to the embodiment shown in the drawings, the mining machine is provided with a base member 1 which is adapted to slide along the floor of a drift or gallery, travel being imparted to said base member by means of a drum 2 keyed to a shaft 3 to which motion may be imparted from a worm wheel 4 through the agency of a clutch 5 provided with a shifting lever 65, which is operated in a well known manner. A cable 7 wound upon the drum2 and secured by a hook 8 to a strut 9, serves to oraw the machine along the wall of coal or other material 10. A motor 11 of any suitable construction is provided with a drive shaft 12, to which is keyed at the forward end thereof a driving worm 13 meshing with the worm wheel t. Immediately to the rear of the motor 11 is mounted a side frame comprising uprights 14, 15 and cross bar 16. Botatably mounted in the base member 1 and an overhanging bracket arm 17 of said side frame is a cutter shaft 18 on which are keyed a plurality of cutter heads 19 for making .-..orizontal kert's within the side wall 10, and also an under cutting cutter head 20. Also keyed to the cutter shaft 18 is a spiral gear 21, by means of which the cutter shaft 18 is rotated from a spiral worm 22 keyed to 11 is a detail sect-ion on the line the drive shaft 12. Journaled within a prowhich meshes a spiral worm 28 rigidly secured to the drive shaft 12 in any suitable manner. The cutters thus far described are adapted to cut the vertical slot 29 (see Fig. 1) and the horizontal slots 30, 31, 32 and 33, shown in Fig. 4 and Fig. 10.

In order to provide eflicient means-for breaking down the coal between the several slots, a plurality of picking devices are mounted on the frame and provided with means "for automatically projecting them into the wall 10. These picking devices, which are preferably three in number, to

correspond with the three ridges of coal,

will now be described.

An upper picking device comprises a reciprocable rod 34 slidably mounted in a boss 35 on the cross bar 16, and also supported by a pedestal 36. Projecting laterallyfrom the reciprocable bar 34, is a cam arm 37, between which and the boss 35 is disposed a resilient member, preferably a spring 38, which spring, when the bar 34 is forced rearwardly, tends to return the bar to its normal position, shown in Fig. 1. A washer or flanged projection 39 is preferably employed for an abutment for one, end of the spring 38. In order to provide means forholding the pick bar 34 temporarily, after the spring 38 has been compressed, the latch or lever 40 pivoted at 41 upon a lug rigid with the boss 35 is provided. This lever 40 is maintained in the path of the washer 39 by a compression spring 42, so that whenever said bar 34 is forced rearwardly a detent 43 on the end of the lever 40 slips over and engages said washer 39. A. vertical shaft 44, which is rotatably mounted in the base member 1, and a bracket arm 45 overhanging from the upright 15, serve to mount a cam plate 46 for each picking device, said cam plate being adapted to force the arm 37 with the bar 34 rearwardly until the washer 39 is engaged by the detent 43. Said shaft 44 has mounted thereon a worm gear 47 which meshes with a spiral worm 48 keyed to drive shaft 12. Exactly similar picking devices are reciproc-ably mounted upon the bars 49 and 50 mounted in a similar manner below the bar 34. Each ofsaid reciprocating picks will therefore be moved into retracted position once each time the shaft 44 is completely rotated. Detent lever 40 is adapted to be oscillated to release any one of said picks by means of a handle 51, which may be grasped by the hand of the operator, or, if

it be desired to make the action continuously automatic, a protuberance 52 may be provided on the handle end. of the lever 40 in suitable position to be engaged by a roller on the end of a crank arm 53 rigidly se cured to an upright shaft 54,'which is rotatably mounted in a boss 55 on the base member 1, and a bracket arm 56 projecting from the upright 14. A spiral gear 57, which is also keyed to the shaft 54. meshes with a spiral worm 58 on the drive shaft 12.

Referring now to Figs. 1, 2, 3 and 4, suitable means. for conveying the cut coal rearwardly from the machine for loading into suitable cars is provided by means of an endless chain conveyer 59 provided with laterally projecting arms 60, which move about the chain sprockets 61 and 62 shown diagrammatically on the drawings. The lower chain sprocket 62 is keyed to the upright shaft 44 and derives its movement therefrom. A chute 63 provided with a side rail 64 serves to support and guide the material as it is delivered to the car 65, as shown in Fig. 4. As shown in Figs. 1 and 4 the receiving end of the conveyer comprises a plate at the lower end of the chute 63 and in the plane of the lowermost horizontal kerf.

In order to provide means for holding the machine against the side wall 10 during its operation, a plurality of struts or posts 66 are employed, which press directly aga inst the outside edge of the base member 1. As the cutting operation proceeds, it becomes necessary to remove the struts 66 out of the path of the upper end of the conveyer chute 63. For this purpose, a hammer 67 is mounted on an oscillable shaft 68 which shaft is provided with a projection 69 disposed to be engaged by one end 70 of a bent lever pivoted intermediately of its ends upon a pin 71 rigidly mounted in the base frame 1. A second lever 72 provided with a detent arm 73 is adapted to engage a projection 74 on said'shaft 68. Said lever 72 is provided with an outwardly curved portion 75, which is adapted to be drawn against a post 66 for setting the hammer 67, said hammer being held by the lever 70 engaging the projection 69. An outwardly projecting arm 76, which, as the machine is drawn forward, is engaged by the post 66, serves to force the detent 70 out of engagement with the projection 69, thus allowing the hammer 67 to deliver a blow on the post 66 under the action of a spring 77, which blow knocks the post 66 down, after which it may be set up in another position in the rear of the machine, as shown at 66 in Fig. 1.

Referring now to Figs=5 and 6, means are shown for ejecting the coal which has been broken down by the picking device 34, into the path of movement of the conveyer. This ejector is provided in the form of an attachment comprising an ejector bar or lever 78,

pivotally supported from the base member ejector bar 78 is hollowed to provide a plate portion 81 and a vertically projecting back or web 82. Means for oscillating the ejector bar is provided by a gear 83 mounted on a shaft 8% extending through the base member 1, and having a crank arm 85 keyed thereto on the other side of the base mem her 1, there being a crank pin 86 rigidly mounted on the arm 85 and pivotally engaging the ejector bar '78. Motion may be imp ted to the gear 83 by a drivi pinion 8} connected with the driving shalt 12.

Referring now to Figs. 7 and 8 which show a modification of the ejector device, the. ejector bar 78 is pivotally connected with the base member 1 at 80, the outer end of the bar being similarly formed to that in the other embodiment. In the modification, however, said ejector bar is adapted to be oscillated by means of an eccentric 88, which is keyed to a short vertical shaft 89 rotatably mounted in the, base member 1 and pro vided with a gear 83 driven by a pinion 87.

A device for further assisting the ejection of the coal into the path of the conveyor is shown in Figs. 9 and 10, and consists of a substantially wedge-shaped block or chute 90 which is adapted to be introduced into the under cut33 formed by the lowermost cutter of the machine. Said block 90 is formed with a cayity in its upper inclined face and tapers away from the column of coal which is being broken down. When a lump of coal 91 drops upon the wedgeshaped block 90, it assumes the position shown in Fig. 10, and has imparted to it a tendency to slide forwardly so that when the end 81 of the ejector bar engages it behind, it becomes easily dislodged, and is thrown on to the lower end of the chute 68 in the path of the conveyor.

In order to provide means for minimizing the quantity of loose particles and dust sus pended in the air about the mining machine and which is produced during the cutting and breaking down operations, an airdisplacing device is made use of which in the present embodiment comprises a rotary fan 93 rigidly mounted on a vertical. shaft 94. The fan 93 is preferably disposedimmediately under the motor 11, the upper end of the shaft 96 havinga flanged pulley 95 keyed thereto and driven by an endless belt 96, said belt being adapted to transmit power from a flanged pulley 97 on the motor shaft 12. by means of guide pulleys 98. An intake trough 99 is connected by means. of a channel or passageway 100 with an axial opening into the fan housing. Said intake trough is elongated as shown in Figure 2 to extend approximately the full height of the gallery or drift within which the machine is at work so that the fan exhausts the dust laden air from all stratas. As shown in Figure 1, the intake opening. of the trough 99 is made to conform to the path of the horizontal grooving cutters. A discharge outlet or pipe 101 projects tangentially from the fan housing which may be connected up in any suitable manner with any receptacle or chamber (not shown on the drawings) in which it may be desired to collect the dust and dirt.
