Specification of Letters Patent.

EARTH-AUGER.

Patented Sept. 30, 1913.

Application filed April 29, 1912. Serial No. 693,794.

To all whom it may concern Be it known that I, DAVID WILSON, a citizen of the United States, and a resident of Kansas City, in the county of Jackson and State of Missouri, have invented-certain new and useful Improvements in Earth- Augers, of which the following is a specification.

My invention relates to improvements in earth augers.

It relates particularly to the type of earth augers in which two conveyer belts are d sposed at opposite sides of and follow a drill shaft,

One object of my invention is to provide a simple, durable and eflicient construction which will permit the excavated dirt to be dumped into a single chute at one side of the machine- A further object of my invention is to provide a novel construction in which the two conveyer belts will occupy a minimum of space transversely relatively to the circle cut by the bit attached to the drill shaft.

Other novel features of my invention are hereinafter fully; described and claimed.

In the accompanying drawings which illustrate the preferred form of my invention, Figure 1 is a side elevation of a machine provided with my invention. Fig. 2

e is a front elevation of the same, with the discharge chute removed. Fig. 3 is'a plan view of the 7 guide frame and parts con-v nected therewith. Fig. 4 is a horizontal section on the line ab of Fig. 6. Fig. 5 is an elevation of the lower part of the auger, showing it in operative position, a well lining section being shown in vertical section. Fig. 6 is a vertical section on the line 'cd of Fig. 3. Fig. 7 is a vertical section on the line ef of Fig. 3.

Similar reference characters designate similar parts in the difierent views.

1 designates a truck having mounted movably thereon a platform 2 to the forward end of which is secured the lower ends of two vertical guide posts, 3, the upper ends of which are connected by across beam 4. Vertically slidably mounted between the posts 3 is a slidalole head 5 in which is rotatively mounted a drill shaft 6 to the lower end of which is secured a bit 7 of any suitable type. I

At opposite sides of the drill shaft 6 are rotatively mounted in the head 5 two horizontal sectional shafts 8, the axes of which.

with buckets 11, and the lower ends of A which belts are respectively mounted on sprockets 12 rotatively inounted on horizontal pins 13 mounted at opposite sides of the drill shaft 6 in a block 14 secured to the lower end of a vertical tube 15 in which the drill shaft is rotatable, and which has its upper end secured by a sleeve 16 to a removable portion 17 of the head 5.

The upper end of the drill shaft 6 is square and fitted in a square socket in the lower end of a vertical shaft 18 which is rotatively mounted in the head 5 and has secured to it a spur gear wheel 19 which meshes with a pinion 20 longitudinally movable on a vertical shaft 21 the upper end of which is rotatively mounted in a bracket 22 secured to the cross beam 4 and the lower end of which is stepped in a block 23 secured to the platform 2. The pinion 20 has a feather 24 which is slidable in a vertical groove 25 provided in the shaft 21. A spur gear wheel 26 is similarly secured on the shaft 21 and meshes with the spur teeth on the periphery of a gear wheel 27 which is rotat-ive on the shaft18 and is provided with internal .teeth which mesh with a pinion 28 secured to a vertical shaft 29 to which is secured a bevel gear wheel 30, which meshes with another bevel gear wheel 31 secured to one of the horizontal shafts 8. The other shaft 8 has secured to it a bevel gear wheel 32 which meshes with a bevel gear wheel 83 secured to a vertical shaft 34, to which is secured a pinion 35 which meshes with the spur or external teeth of the gear wheel 27. The shafts 29 and 34 are rotatively mounted in the head 5.

When the shaft 21 is rotated the drill shaft 6 is rotated by means of the pinion 20, gear wheel 19 and shaft 18, and the two conveyer belts are driven in like direction by means of the sprockets 9, shafts 8, bevel gear wheels 31, 32, 30 and 83, shafts 29 and 24, pinions 28 and 35, and gear wheels 27 and 26 just described.

Any suitable means may be employed for rotating the shaft 21 as, for example an engine 36 .mounted on the platform 2 and having suitable driving mechanism connecting it with the shaft 21.

operated by the engine 36.

In the operation of my invention, as the drill shaft 6'is driven and lowered, the conveyer belts 10 will be driven in a like direction by the mechanism described, the buckets 11 will pick up the dirt dug up by the bit 7 and carry it upwardly where it may be delivered by the buckets into a single chute 37, shown in Fig. 1, and which is secured to the head 5. By driving the belts 10 in the same direction but one chute is needed to receive the discharged dirt. By having the axes of the sprockets 9 in the same plane as the drill shaft 6, the belts may be carried farther into the hole made by the bit 7, than would be the case if the shafts 8 were at one side of the plane of the drill shaft.

The manner of placing the tubular linings, one of which is shown in Fig. 5 and designated by 38, is fully described in the application aforesaid.

I do not limit my invention to the specific structure shown and described, as modifications, within the scope of the appended. claims, may be made without departing from the spirit of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is

1. In an earth auger, a drill shaft, two sprockets disposed at opposite sides of the drill shaft and having their axes located in a plane which longitudinally bisects the drill shaft, two conveyer belts respectively driven by said sprockets, a gear wheel having spur teeth and internal teeth, means actuated respectively by said spur and internal teeth for driving said belts in a like direction, and means for actuating said gear wheel and simultaneously actuating said drill shaft.
