UNITED STATES PATENT OFFICEO JOHN MILES, orMooREsvILLn, TEXAS.
POST-AUGEJR.
- SPECIFICATION forming part of Letters Patent No. 283,010, dated August 14, 1883.
Application filed May 17, 1883. (No model.)
To aZZ whom it may concerns Be it known that I, JOHN E. MILES, 0 Mooresville, in the county of Falls and State of Texas, have invented certain new and useful Improvementsin Post-Augers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part, of this specification,
Figure 1 is a perspective view of my im- Fig. 2 is a longitudinal vertical section of the same; and Fig-3 is a cross-section on line as :0, Figs. 1 and 2.
Similar letters of reference indicate corresponding parts in all the figures.
My invention has relation to that class of post-angers which consist'of a number of concavo-convex cutting-blades secured upon the lower end of a shaft having a cross-handle a its upper end, and provided with means for expanding the said blades for the purpose of boring holes of different'sizes; and it consists in the detailed construction and combination of parts of the same, as hereinafter more fully described and claimed.
ln the accompanying drawings, the letterA indicatesthe shaft, having the cross-handle B upon its upper end, and having a block, 0, fastened upon its lower end, which block has a number of segmental recesses or sockets, D, concentrically arranged around its center, opening from its lower end, all the sockets forming segments of the same circle. transverse perforations, E, pass from the outside of the block radially into. the periphery of each of these sockets, and are screw-threaded for the reception of a number of set-screws,
F, the number of perforations and of screws corresponding to the number of sockets.
These screws serveto secure the blades G, the upper ends of which form concavo-conve'x cylinder-segments, concentric with and of the same width as the sockets, into which they fit, while their lower'portions are concavo-convex, and curved or bulging at their middle, so that they may cut into the sides of the hole while boring withtheir sharpened edges, each A number of blade having one edge sharpened. A screw",
threaded rod. H, extends from the center of their springiness,'boring a larger or smaller hole, as desired.
It will be seen that by having the circular disk between i the blades it will serve to raise the dirt bored or cut loose by the blades, which is worked in boring upon the top of the disk, where it rests, and may be raised out of the hole. It will also be seen that by having the upper ends of the blades fitting into the sockets in the block upon the end of the shaft, the blades may be removed for the purpose of sharpening them, or if any accident should happen to them; and the trouble generally experienced by this class of earth-angers, in which the blades usually are fastened in recesses in the sides of the block or ring. upon the lower end of the shaftviz., the filling up of the recesses with dirt-is avoided by this construction, the ends of the blades filling the'sockets completely, prevent ing the dirt from working up into them, whiclv is also prevented by the sockets being covered upon all sides, excepting at the lower end, where the blades fill them up.
I am aware that earth-angers have been made with detachable curved cutting-blades, and I amlikewise aware that the expanderdisk is not broadly new, and I do not wish to claim either of these features, broadly; but
What I claim, and desire to secure by Letters Patent of the United States, is-
1. The combination, in a post-auger, of the 1 socketed block, the screw-threaded rod extending from the center of the lower end of the block, the circular expander-disk fitting and turning with its central female threaded perforation upon the rod, and the concavoconvex curved blades, as and for the purpose shown and set forth.- 2. The herein-described post-auger, consisting of the shaft, the cross-handle, the socketed In testimony that I claim the foregoing as 0 block, the concavo-convex curved blades, the my own I have hereunto affixed my signature set-screws securing the blades in their sockin presence of two Witnesses. v ets, the screw-threaded rod extending from p the center of the lower end of the block, and JOHN E. MILES.
the expanderdisk fitting and turning with its female threaded central perforation upon the Vitnesses:
screw-threaded rod, as and for the purpose W. WV. DAVIS, Jn,
shown and set forth. I J. B. APPLEBY.
