mNrNe AND LOADING MACHINE.

-Application filed November 3, 1917, Serial No. 200,174. Renewed April 18, 1924.

To all whom it may concern:

Be it known that I, WALTER J. WILSON, a citizen of the United States, residing at Sewickley, in the county of Allegheny and State of Pennsylvania, have'invented 'certain new and useful Improvements in Min- 1ng and Loading Machines, of which the following is a specification.

. This invention relates to machines for excavating material such as coal or the like, and elevating, or carrying the excavated material back for loading.

The objects of this invention are to prov1de a new and improved form of mining machine; to provide a mining machine which will excavate the material and elevate it or carry it back to a suitable position for loading; to provide a coal mining machine which will excavate and load substantially 2 all of the coal to be taken-out of a room or entry; andin general to provide such an improved apparatus as will be described more fully hereinafter. I

In the accompanying drawings illustrating this'invention:

- Fig.1 is the side view of a machine embodying the principal features of this invention, parts being shown diagrammatically or omitted for convenience in illustration;

Fig. 2 is a plan view of the machine shown in Fig. 1;

Fig. 3 is a modified form-of construction, and,

- Fig. 4 is a plan view of the machine shown in Fig. 3.

' Fig. 5 is a detail showing a clutch and'reversmg device.- H

The present invention embodies a cutting apparatus, preferably of the chain and bit type, which is mounted and arranged tocut the coal or other material and carry it back to asuitable discharge point, means also be-.

ing provided for actuating the cutting apparatus so as to swing it either vertically or horizontally or in both directions in order to cutsubstantially all of the material from an entry or from the side of a room.

Y As illustrated in Figs. 1 and 2, 5 is a support or carriage having wheels 6 which are preferably arranged to run on a track 7.

a side view of a machine showing The car or carriage 6 isprovided with a frame or standards 8 having bearings 9 at the top thereof. A beam or arm 10, which may be constructed in any suitable manner, is pivotally mounted on a shaft 11 which engages with the bearings 9. of the supporting carriage. The beam or arm 10 is mounte so that its forward end may beraised and lowered to cut a vertical kerf, and suitable means are provided for swinging the same. In the present instance, I provide screws 12 having hand wheels 13 for turning them. The upper and lower ends of these screws are provided respectively'with right and left hand threads which engage with nuts 14 and 15. The nuts 14. are suitably secured to the beam 10 and the nuts 15 are suitably secured to the base of the carriage 5 so that when the hand wheels are turned, thebeam 10 will be raised or lowered.

The. beam or arm 10 is provided with means for supporting and guiding the cutting devices. While in some instances I may utilize series of cutting devices, in the present instance I show a single cutter cham 16 which is mounted on wheels 17 and 18 at either end of the cutter arm. 'The chain 16 is provided with bits 19 which are mounted so that the chain 'cuts under and over as illustrated in Fig. 1. v A motor.20 is mounted on the carria e 5 and is provided with a sprocket whee 21 which drives a chain 22 WhlCl'l in turn drives sprocket 23 on the shaft 11. This shaft has a second sprocket 24 which drives a chain 25 for turning a sprocket 26 on the shaft 27 chain, but it is obvious that such driving mechanism may be varied for different conditions.

.which shaft drives a sprocket 17 for actu- In order to insure the delivery of sub-- stantially all of'the excavated materlal, a

chute ortrough is arranged along the up-. per part of the cutter arm. Th1s chute 1s shown as comprising a fixed section 28 and a movable section 29 Thearrangement is such that, as the cutter arm passes into the material, the forward end of the section 29 will engage with the face of the wall and this section will be graduall pushed backward into the. fixed section. 1118 provides a conveyor arran ement for conveying the excavated materia? backwardly so that it may be discharged into the mine car 30, or in a suitable position for loading.

The carriage ma be moved along the track either manna ly, or by any suitable mechanical arrangement. As illustrating such arrangement, the driving shaft of the motor 20 has a gear 31 which meshes with a gear 32 on a shaft 33 mounted in suitable bearings transversely of the carriage. This shaft 1s provided with a sprocket wheel 34 which engages with a chain 35 extending lengthwise of the track 7. The front and rear ends of this chain are fixed at 36 and 37 respectively to the ties or to any other suitab e anchors. Guide wheels or sprockets 38 ma also be pro'videdpn the carria e to hold t 9 chain in engagement with the riving sprocket 34. Any suitable clutch and reversing arrangement'may be used for throwing this feeding mechanism into and out of operation, or the motor may be reversed to cause the carriage to move back ward along the chain 35. Such an arrangement is shown in Fig, 5, which illustrates a well-known form of reversing mechanism. The gear 31 is loosely mounted on the drivin shaft 71 of the motor 20 and is provi ed with a clutch j aw 72, which is adapted to 'be' engaged by'a clutch member, 73 fitted on a spline in the shaft 71. The opposite end of this clutch member is adapted to engage with a clutch jaw 74, which is secured to a sprocket loosely mounted on the shaft 71. The sprocket 75 is connected bly means of a chain 76 to a sprocket 77 on te shaft 33. When the clutch is thrown into engagement with the jaw on the gear 31, the shaft 33 will be turned in one direction, and when the clutch is thrown into enga ment with the jaw on the s rocket whee 7 the shaft 33 will be turne in the opposite direction.

When the machine is to be operated, it is moved to cutting position on the track 7 and the ends of the chain 35 are fixed to suitable supports. Ordinarily the front end of the cutter arm will be lowered to the position shown in Fig. 1 for making the initial out. With the arm in this position, the machine is fed forward and the cutter bits will excavate the material and elevate it so that it will be carried back through the chute at Ithe top of the cuthd ter arm and be delivered into the car 30.

As the forward end of'the cutter arm passes into the material, the movable chute 29 will elevate the forward end of the arm so as to cut a vertical kerf up to the top of the remains. This triangular area is then excavated by backing the machine away from the face of the coal with the forward end of the cutter bar held in its elevated position so that a com lete cut is made from the' floor to the roo of'the mine.- During the last described movement, it is apparent that the cutter bar will be moving backwardly from the face of the coal, and in order to catch the cuttings, the movable shoot section 29 should be moved toward the face of the coal or held so that its inner end will remain in contact with, or adjacent to the face. This section may be moved or held in such position in anysuitable manner, as by hand.

In the machine shown in Figs. 3 and 4,

a car or support 40 is provided with a robeams 44 and provides a continuous bed or trough along which the coal is conveyed. Adjusting screws 49, having hand wheels 50, provide means for raising and lowering the forward end ofthe cutting mechanism. The lower ends of these screws engage with bearings 51 which are pivoted at 52 to the carriage 42, and their upper ends engage with nuts 53 secured to the sides of the cutter arm 43.

A motor 54 is mounted on the carriage 42 and drives a sprocket wheel 55 which drives a chain 56 engaging with a sprocket wheel 57 on a shaft 58, u on which the cutter arm is pivoted, or w' ich is concentrio with the pivotal mounting of said arm. 1

The shaft 58 drives a sprocket wheel 59 which drives a chain 60, which drives a sprocket wheel 61 on a shaft 62 at the upper end of the cutter arm, which shaft drives the sprocket wheels 46 for the cutter chains.

Any suitable means may be utilized for feeding the carriage 42 along the bed or turn table. 41. As shown, a motor 54 is provided with a gear 63 which meshes with a gear 64 on a stub shaft 65. This shaft drives a bevel-gear 66 which meshes with a gear 67 on a stub shaft 68. The shaft- 68 carries a worm 69 which engages with a rack 70 on the bed 41. By meansof this arrangement, it will be seen that as the worm 69 is turned, it will cause the carriage -12 to move forward or back along the bed 41.

This machine may be operated in various ways, one of which is as follows. The machine is moved up on the track to its initial 1 cutting position substantially as shown in Fig. 3 and the truck or support 40 is then blocked or held against movement along the track in any suitable manner. The cutting apparatus is then started in operation and the carriage 42 is fed forward until the cutter arm reaches the position indicated by the lower dotted lines in Fig. 3. The forward feeding is then stopped by means of any suitable clutch and reversing mechanism (not shown). The forward end of the cutter bar is then gradually swung upwardly by means of the adjusting screws 49 until -it reaches the position indicated by the upper dotted lines. The cutter bar is then held 1n this position and the carria e is then fed backwardl so as to cut out t e triangular section in icated at the top of Fig. 3. In the particular design shown, it will be noted that the back end of the cutter arm and conveyor may. be lowered to a position below the top of the mine car, but the parts may be proportioned so that this outer end will arrangement being substantially the same always be in a suflicientlyelevated position to discharge the coal into the car, or an auxiliary conveyor may be utilized if desired for carryin the coal back and into the coal car. It wil also be readily seen that in both forms of this invention, the cutting device may be moved forwardly and swung upwardly simultaneously,thereby making a somewhat sweeping out. The cutter bar' or arm-43 in this particular machine may also be provided with a chute, such as shown in Figs. 1 and 2 and as indicated at 77 by the dotted lines in Fig. 3, the construction and .ax1s with achain having cutter bits coacting therewith and adapted to cut a kerf sufliciently wide to 'admitthe bar, means for swinging said'bar in a vertical plane to cut a vertical kerf, and means along said cutter bar adapted to keep the cuttings within the range. 0 the cutter chain to provide a conveyor for conveying the excavated material.
