AUGER.

--App1ication filed August 13, 1921. Serial No. 491,984.

To `all whom t may concern:

' Beit knownthat'l, LoUIs Fltlnss, a citi- Zen'of the United States, residing at Ansted, inthe county of Fayette and State of West Virginia, have invented av new and useful Augen of which'the following fis a vspecification.

It is the object of' this invention to kprovide a simple attachment fora mining machine, whereby the blast holes maybe bored vin the breast of the working, at the kwill of an operator, novel means being providedvfor rotatingthe auger shaft whereby the holes are bored', and novel means being-provided for advancing' the augershaft todeepen the holes.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type tov which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the inventionresides in the combination andarrangement ofparts and in the details of construction hereinafter described and claimed, it being understood that, within the scope` of what is claimed, changes in the precisey ,embodiment yof the invention shown can be made without departing from the spirit of the invent-ion.

In the accompanying drawings Figure 1 shows in side elevation, a device constructed in accordance with the inv-ention, parts being broken away; Figure 2 is a top plan; and Figure 3 is a sectional detail showing a portion of the means where by the boring shaft is advanced longitudinally, at the will of an operator.

rlhe numeral 1 denotes the body of a mining machine of known form, the numeral 2 designating the auger or cutting member which, working along or adjacent to the floor of the mine, undercuts the breast. The auger 2 is driven by a shaft 3 carrying` a gear wheel 4 meshing into a pinion 5 carried by a power driven shaft 6, operated by a motor of any suitable sort, (not shown).

Bearings 7 are mounted on the body 1 of the mining machine, and in the bearings 7 a first shaft 8 is journaled for rotation. The shaft 8 is provided with a gear wheel 9 meshing into the pinion 5. A frame 10 is erected on the body 1 of the mining machine, one end of the shaft 8 being journaled in 'the frame. A Vsecond kshaft -11 is journaled inthe frame 10 andis Vdisposedhat right angles to the shaftf8, theshaftsjve8-,and 11 being connected operatively by vintermeshing beveled pinio-ns 12. A third shaft 14 is mounted to rotate in the upperefportion of the frame 10 and is disposed approximately parallelrto theshaft 8. Thef shaft 14 `is an augerjshaftand carries alcouplinglh of anydesired sort, adapted 'to retainthe augerv 16 by which the holes ,for the blastyingcharge are fbored. The third `shaft 14 is connected operatively kvwith the second shaft 11, through the instrumentality'vof beveled pinions 18.

The shaft 6, being power driven, opera tes the-pinion 5, and the pinion 5 transmitsinotion to the gear wheel 9, rotation being imparted vto the shaft 8. -F rom the shaft 8rois mounted e for `right line Areciprocation `in the frame 10, the means is providedlwhereby theshaft 14-andthe1auger 16 lmayloeaclvanced. The shaft 11 carries a/worm`f20, meshing 4into aworm wheel 21fvsecured to a fourth shaft 22 mounted to rotate onthe frame 10 and dis osed, ordinarily, at right angles to the shaft 11. A sprocket wheel 26 is loose on the shaft 22 but may rotate with the shaft and the worm wheel 21. About the sprocket wheel 26 is engaged a sprocket chain 27 one end 28 of which hangs free, the other end of which is connected at 29 to a foot piece 30 wherein the rear end of the third shaft 14 is received for rotation. The sprocket wheel 26 includes a clutch member 33 cooperating with a clutch member 34 splined as at 35 to the shaft 22 to slide therealong. An abutment collar 36 is attached by screw 37 to the shaft 22.

Any suitable means may be provided for forcing the clutch member 34 to the left (Figure 3) as to cause the said clutch member to engage the clutch member 33. lf desired, levers 40 may be fulcrumed at 41 on the frame 10, wheels 45 being journaled on the ends ofthe levers 40,.the wheels having wedge-shaped peripheries, as shown in Figure 3. A lever under the control of an operator, may be fulcrumed at 51 on the frame l0, the lever including an upstanding arm 52 provided with a slot 53 receiving the shaft 54 of a roller 55 operating between the levers 40. v

In practical operation, the worm 20 drives the Worm Wheel 21 continuously, the worm Wheel 21 rotating with the shaft 22, the sprocket Wheel 26, however, remaining at rest on the shaft 22. When the leverI 50 is swung downwardly, the arm 52 carries the roller 55 backwardly between the levers 40, the beveled wheels 55 being interposed between the collar 36 and the clutch member 34, the clutch member 34 being moved to the left in Figure 3 and, cooperating with the clutch member 33 serving to press the sprocket Wheel 26 against the worm wheel 21, so that when the worm wheel 21 is rotated, the sprocket wheel 26 will participate in the rotation. When the sprocket wheel 26 is rotated, the Vlchain 27 will be caused to pass over the sprocket Wheel, the foot piece v3() being advanced, and the shaft 14 and the auger 16 being advanced with respect to the work.

1. A mining machine comprising a body, a frame mounted on the upper portion of the body, a substantially horizontal first shaft supported for rotation on the upper portion of the body, a substantially vertical second shaft journaled in the frame, beveled pinions connecting the first and second shafts, an approximately horizontal third shaft journaled in the frame and slidable therein, an auger carried by the third shaft, beveled pinions connecting the second and third shafts, means driven by the second shaft for advancing the third shaft, and a clutch under the control of an operator and interposed in the last specified means.

2. In a mining machine, a body, a frame erected thereon, a substantially vertical shaft journaled in the frame, a substantially horizontal shaft journaled in the frame, an auger carried by the last specified shaft, means for connecting the shafts, another shaft journaled in the frame and disposed m a substantially horizontal position at right angles to the first and second specified shafts, a worm and worm wheel connection between said other shaft and the vertical shaft, a sprocket wheel loose on said other shaft, a clutch connection between the sprocket wheel and said other shaft, and a chain engaged with the sprocket wheel and with thev substantially horizontal shaft and constituting a feeding means therefor.

3. A device of the class described comprising a frame, van auger shaft ournaled in the frame, an auger carried by the auger shaft, another shaft journaled in the frame, means for driving both shafts, mechanism driven by said other shaft for feeding the auger shaft, a clutch connecting said mechanism with said other shaft, levers fulcrumed intermediate their ends on the frame and coacting at their inner ends with the clutch, and a second lever under the control of an operator and fulcrumed on the frame, the second lever comprising a part movable between the outer ends of the first specified levers, to cause the inner ends thereof to coact with the clutch.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
