POST-HOLE BORER.

SPECIFICATION forming part of Letters Patent N0. 753,239, dated March 1, 1904.

i Application filed October 29, 1903- Serial No. 179,033. (No model.)

To aZZ whom, it may concern.-

Be it known that I, MEREDITH P. CURLEE,

a citizen of the United States, residing at' McKenzie, in the county of Butler and State of Alabama, have invented new and useful Improvements in Post-Hole Borers, of which the following is a specification.

My invention relates to post-hole borers, and has for its object to provide a simple and efiicientmachine of this kind.

A further object is to mount the auger-shaft in such a way that it can be swung sidewise to enable the machine to bore a vertical hole on a hillside. With this and other objects in view the invention consists in certain novel features of construction hereinafter described and claimed, and shown in the accompanying drawings, in which Figure 1 is afront elevation, and 'Fig. 2 is a side elevation.

Referring specifically to the drawings, 4 indicates the frame in which the working parts of the machine are mounted. Said frame comprises sills 5, to which standards 6 are secured. Beams 7 extend across the top of the standards, of which there are four, two on each side, forming a rectangular frame. The standards are slotted, as at 6,and between each pair of the same a block 8 extends, having reduced ends 8 fitting in'the slots.- Drivingshafts 9 extend through a bearing-hole in each block and carry at their outer ends a suitable hand-crank 9. Between the inner ends of the shafts a block 10 is placed, in which the ends of said shafts are journaled. The auger-- wardly with the auger-shaft as the hole is bored. That portion of the auger-shaft which extends through the block 10 is round, so that it can rotate, while below the block it has a shoulder 10, so that the block cannot slip down on the shaft. As the ends of the driving-shafts set loosely in the block 10, it can be swung sidewise, thus causing the, auger-shaft to extend at an angle to the frame, permitting the machine to bore a vertical hole when it is used on a hillside. Any suitable means may be used for raising the auger-shaft after the hole is bored. I have shown a lever 14 fulcrumed to the top of the frame and connected to the end of the shaft;

Having thus described my invention, what is claimed as new, and desired to be secured by Letters Patent,

1. A post-hole borer comprising a frame, alined driving-shafts vertically slidable therein, a swinging block between the drivingshafts and receiving the inner ends thereof,

an auger-shaft extending through said block, and meshing gears on the driving and auger shafts. I

2. A post-hole borer comprising a frame,
