POSTc-HOLE AUGER.

Specification of Letters Patent.

Patented Dec. 1, 1908.

Application filed January 24, 1908. Serial No. 412,486,

T 0 all whom it may concern:

Be it known that 1, WILLIAM J. MILLER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Im rovements in Post-Hole Angers, of which the following is a specification.

This invention relates to earth augers, and the object of the invention is to provide a sim le device of this character, provided wit a holding means having spurs adapted for insertion within the ground, and provided with a central internally threaded coupling adapted for engagement with the threads u on a standard carrying the auger blades an the handle by which the anger is rotated, thus providing means for boring holes in the ground with a very slight amount of hysical exertion.

other object of the invention is to rovide a threaded standard having a holding device adapted for insertion in the earth, the standard being provided with means whereby an auger blade and auger handle of the ordinary construction may be readily applied thereto.

With these and other objects in view the invention resides in the novel construction of elements and their arrangement in operative combination as will hereinafter be fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of an earth auger constructed in accordance with my invention. Fig. 2 is a top plan view of the bit. Fig. 3 is a detail sectional view of the upper portion of the standard and its reduced extension, by which the standard is connected with a handle of the ordinary construction. Fig. 4 is a detail sectional view of a portion of the auger, illustrating the manner by which the anger is connected with the standard employed in my invention.

1n the accompanying drawings the numeral 1 designates the standard employed with my invention. The standard is referably tubular in cross section, and 18 provided with threads u on its outer surface running the entire ength thereof. The upper and lower portions of the tubular standard 1 are also provided with internal threads extending a suitable distance within the bore of the standard.

Positioned upon the lower extremit of the standard 1, is an earth auger 2, o the usual construction, comprising a point 3 and blades 4, and having the upstanding collar 5 provided with a threaded recess, coinciding with the threaded lower portion of the standard 1. Connected with the threads of the collar 5 and the internal threads of the lower portion of the standard 1 is a suitable threaded member 6, adapted to secure the auger and the standard together. The collar 5 is provided with a suitable threaded perforation 7, adapted for the reception of a bolt 8 which bears against the member 6, and effectively retains the auger in position upon the standard 1.

Positioned upon the standard 1 is aholding device 9, comprising a central threaded coupling 10, adapted for engagement with the threads of the standard 1, and provided with diametrically op osite extendingarms 11 having downwar y projecting, right angular spurs 12.

The upper internal threads of the standard 1 are adapted for the reception of a threaded extension 13, the free end of which being adapted for engagin the threaded nipple 14 provided upon a col ar or strap 15 in which is positioned a handle 16, adapted to extend upon either side of the collar 15.

The 0 eration of my device is as follows: The hol ing device is revolved until it is positioned at the lower extremity of the standard 1, and against the collar 5 of the auger. The point 3 of the auger is inserted within the earth, as are the spurs 12 of the holding device. The operator places his foot upon the extensions 11 of the holding device to prevent them from moving, and the handle 16 is turned causing the threaded standard 1 to revolve within the threaded coupling 10 of the holding device. When the spurs 11 are sufficiently embedded within the earth the descent of the auger bit, it is no longer necessary for the o erator to hold them in position, and the handle may be easil turned within the cou ling 10 and the ho ding device forms an e ective support for the stand ard.

With a device constructed as above described it will be seen that an auger may be driven into the earth with a very small amount of h sical exertion, as the pressure of the cart is effectively overcome by the threaded connection between the standard 1 and the cou ling 12 of the holding device. It will be still further seen that my device is applicable to earth angers and handles therefor now in common use, that it is extremely standard, a collar secured to said extension,

simple in construction, durable, and effective in o eration.

I avin r thus fully described the invention what is c aimed as new is:

In a device of the character described, a tubular standard rovided with external threads, internal t ireads near both of its ends, a threaded extension engaging the internal threads at the opposite portion of the a handle carried by said collar, a holding device upon the standard, said holding device comprising a central threaded portion and extensions having downwardly extending spurs, a threaded member adapted to engage the lower internal threads of the standard, and an earth auger having a threaded collar adapted to engage the threaded member, the collar of the auger having a right angular threaded orifice, and a threaded element adapted to enga e the orifice and contact with the threade member within the collar.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM J. MILLER. Witnesses Mrs. W. J. MILLER, JULIA M. MILLER.
