IMPROVEMENT IN COUPLINGS FOR E ARTH-AUGER SHAFTS.
Specification forming part of Letters Patent No. 140,710, dated July 8,1873; application filed January 2, 1873.
To all whom it may concern:
Be it known that we, GEORGE W. IRWIN and THEODORE A. Cox, of the county of Ghampaign and State of Illinois, have invented a new and useful Improvement in Coup lin gs for Well-Angers; and we do hereby declare that the following isa full, clear, and
Y exact specification thereof.
Our invention relates to the connecting of well-auger shafts in such a manner that they can'be easily adjusted, and at the same time form a solid, upright, and self -supporting shaft, one that can be turned either to the right or left Without danger of becoming disconnected. a
By raising the slide H, by means of force applied to the screw-bolt a, the projection e is most, or quite, as solid as the other portions of the shaft. i
The object of the invention is to form a joint that shall be readily connected and disconnected, and that shall allow the shaft to be turned either to the right or left without danger of becoming disconnected, and in reversing the force applied to have as little play as possible, and at the same time form a selfsupporting shaft, and thereby do away with the necessity (when boring in an excavated well) of placing supporters around the shaft to keep the jointed portion from swaying to either or both sides of the well at one and the same time.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-- In couplings for earth auger shafts, the combination of the flanged and the projection g with the slide H,.substantially as and for the purpose hereinbefore set forth.
GEORGE W. IRWIN.
Witnesses: THEODORE A. COX.
