' METHOD OR PROCESS Q1 OPERATING-AUGERB.

- Application filed November To all whom it concern:

Be it known that I, WILLIAM E. Moore, a citizen of the United States, residing at Chicago, in the county of Cook and State of.

Illinois, have invented certain new and useful Improvements in Methods or Processes of Operating Augers, of which the following is a specification. a p

Tlns invention relates to a method or process of operating augers.

It is articularly advantageous in the borin of oles in the earth.

eretofore it has been the practice, in

the operation of earth boring augers, to manually remove the earth from the auger or to provide mechanical scrapers and conveyers for automatically freemg the auger from its load. These methods require long and arduous manual labor or the provision of more or less complicated mechanism which is always liable to clog, break or otherwise prove troublesome, expensive and unsatisfactory.

One of the objects of this" invention is to provide an improved method of operating au ers.

nother object is to provide an improved method of boring holes 1n the earth.

Another object is to provide a method whereby both manual labor and mechanical complication are reduced to a minimum.

.Other objects and advantages will appear from the specification and claims.

In general the method'comprehends the advancement of the auger while "it is. being rotated at one speed, and accelerating the rotationlof the auger during or after its withdrawal to thrgw off the load by centrifugal action.

The method will be described in connection with the accompanying drawings which illustrate one form of boring machines that mziy be employed.

F1g. 2 is a-top plan thereof, and

Fig. 3 is. anend elevation of a part of the auger driving mechanism. v

details are omitted from the drawin s, because the method hereinafter describe does not depend upon and is not peculiar to any particular type of machine. The structure of an earth boring machine which has been found to give excellent results in the practice of the present process is disclosed in my co ending application Serial No. 292,133 filed pril23,1919.

In general the earth boring machine com-v prises an auger tower 5 within which is located an auger shaft 6, carrying at its lower end an earth boring auger 7 The.aug tower is mounted u on a turntable 8 rotatably carried upon t e chassis of the truck. By means of the turntable the auger can be accurately positioned above the .place where a hole is to be made.

The drive shaft of the engine of the truck is c0nnected,--.by a sprocket wheel and chain connection 9, to a counter shaft 10. Shaft 10, through suitable beveled gear trains and a vertical shaft on the axis of the turntable drives a counter shaft 11. Shaft 11 is jour naled in suitable bearings 12 and 13. mounted 1 on the turntable. Through shaft 11 the enfor elevating and lowering the auger.

The engine rotates the anger alwa s in the same direction. Shaft 11 has a evel gear wheel 15 keyed thereto. Gear wheel 15 drives a gear wheel 16 keyed to a shaft 17 Shaft 17 extends across the turntable and has keyed thereto a clutch member 18. Clutch member 18 is adapted to slide on shaft 17 into and out of drivin connection with a cooperating clutch member 19 which forms a art of a-sprocket wheel 20 loosely journale on shaft 17. Clutch members 18' and 19 are thrown into and out of driving position by an operators lever 21.

Sprocket wheel 20, through a chain 25 drives a s rocket wheel 26,,keyed to a shaft 27 journa ed on the turntable. Shaft 27 has a beveled pinion 28 keyed-thereto and this pinion engages a cooperatin beveled gear wheel .29. Gear wheels 2% and 28 are mounted in a gear box 30 which supports the auger tower and-through which the auger shaft passes. Gear wheel 29 is rovided with a squareopening through whic auger shaft 6, which is also of square cross-section, is longitudinally slidable. Thus the rotation of gear wheel 29 rotates the auger shaft and" auger in any position of the auger or while I the auger is being raised and lowered.

The engine also acts to raise and lower the auger. Shaft 11, in addition to gear wheel 15, also has a beveled gear Wheel 33, secured thereto and engaging a bevel gear wheel 34 loosely mounted on a sleeve encir cling shaft- 17. This sleeve has a sprocket wheel 35 and a doubleacting clutch member 36 keyed thereto. A beveled gear wheel 37 loosely journaled on this sleeve engages gear v 7 wheel 15.

When clutch member 36 is moved in one direction, it cooperates with a clutch memher on gear wheel 34 and the sleeve and sprocket wheel 35 are driven in one direction. When the position of clutch member 36 is reversed, it engages a clutch member on gear wheel 37 and the sleeve and sprocket wheel 35 are driven in the reverse direction. Clutch member 36 is controlled by an operators lever 38.

Sprocket wheel 35, through a chain 40,

' drives a sprocket wheel 41 loosely iournaled on shaft 27. Sprocket wheel 41 isrigidly connected to a sprocket wheel 42 also loosely journaled on-shaft 27. Through chain 43 and a sprocket wheel 44 sprocket wheel 42.

drives a shaft 45 journaled to the auger tower near its bottom. Shaft 45 carries a sprocket wheel 46 keyed thereto. A chain 48 passes over sprocket wheel 46. and a similar sprocket wheel 49 which is located near the top of the tower. Chain 48 is secured to auger shaft 6 by a coupling 49, the'coupling being of such construction that the shaft is free to rotate.

Thus the augur shaft and anger are raised and lowered, depending upon the position of lever 38, by sprocket wheel 35, chain .40, sprocket wheels 41 and 42, chain 43, sprocket .wheels 44 and 46, and chain 48.

or in the case of extremely heavy and sticky soil the auger has penetrated to about the limit of the extent of its best operation, lever 38'is thrown to cause the raising of the auger. As the auger emerges from the hole or after it is completely removed therefrom its rotation is accelerated in any desired manner, as by speeding up the engine. The higher speed of rotation increases the centrifugal action tending to throw ofl or expel the load of earth elevated by the au er. The speed of rotation may be increase to such an ektent that the earth is thrown or exdpelled from the auger and clear-of the hole. When the auger is completely freed of earth its speed of rotation may be'decreased and, if the hole is not of the desired depth, the boring operation may proceed.

This method of operating augers and boring holes has been found to give excellent results. No scrapers, conveyers or arduous manual labor are required to free the auger of its load. The earth is readily expelled by centrifugal action and a clean hole is quickly and advantageously provided.

Having described my invention, what I claim is v1. The method of operating angers which comprises, advancing the auger at one speed of rotation, and subsequently accelerating the rotation of the auger toexpel the load by centrifugal. action.

2. The method of boring holes in the earth which comprises, advancing the auger into the earth at one speed of rotation; withandrotating the auger at a higher speed to expel the load by centrifugal action.

3.. The method of boring holes which comprises, loading the auger, withdrawing the auger from the hole produced in the loading thereof, and expelling the load from the auger by the effect of centrifugal action.

4. The method of boring holes in the earth which comprises, advancing the auger to bore the hole, loading the auger during the boring operation, withdrawing the auger and its load of earth from the hole, and rotatin the auger at a higher speed than require to bore the hole to clear the auger of its load of earth In testimony whereof I hereunto subscribe my name.
