SUPPORT FOR ROCK-DRILLS.
SPECIFICATION forming part of Letters Patent No. 325,564, dated September l, 1885.
App'icat-ion filed Apr-i127, 1885.
To all whom t may concern:l
Be it known that I, GEORGE W. NIXoN, a citizen of the United States, residing at Rockwood, in the county of Roane and State of Tennessee, have invented a new and useful Improvement in Rock-Drill Supports, of which the following is a description.
This invention relates to that class of devices which are used for drilling holes in the process ol' coal-mining and sinking shafts in rock, Sec. and its object is to provide a base against which a drill propelled by a ratchetlevenor similar device may push to force itself into the rock, and to provide means whereby the ratchetdrill may be quickly readj usted after it has extended to its limit.
To this end my invention consists in the construction and combination of parts forming a rock-d rill support, hereinafter described and claimed, reference being had to the accompunying drawings, in which- Figure l is a longitudinal vertical section of a ruine-shaft, showing-inyinvention in side elevatiou. Eig. 2 is a longitudinal section ofthe support; and Fig. 3 is a transverse section of the support, showing, also, a portion of a ratchet-drill and the supporting-dog.
A. represents a shaft in a rock, B. G is a drill secured in a ratchet-drill stock, D, to be revolved in drilling` by a reciprocating motion of the stock.
E represents the body of my support, consistiug of a metal pipe pointed at one end to rest in a small cavity to be made in the wall ofthe shaft for that purpose, and re-enforced at the other end by a collar or ferrule, F, to give it strength and to furnish snlicient thickness to hold a set-screw, G.
H is a smaller metallic tube, fitted to telescope. within the tube E, and adapted to be extended therefrom and to be rigidly fixed (No model.)
thereto by the set-screw G. By this means the support may be quickly leugthened, so as to extend nearly across the shaft A.
the tube H, to be stepped in a small hole made in the wall for that purpose.
K is a hand-lever, by which the tube H is revolved around the screw, to extend or retract the screw the amount necessary to .tit the support tightly between the two walls of a Shaft.
As the tubes H and E may be set to very nearly rea-ch across the shaft, the screw J need not be more than three inches long for general use.
The end of the tube E has a turned conical not pointed, so that thescrew will stick against the rock while the tube turns thereon.
The ratchet-drill stock D is provided with the usual screw-sleeve, L, from which the screw M is gradually extended, to advance the drill C into the rock while drilling.
N is a sleeve, having a set-screw', P, by which it may be secured at any point along the sleeve of the drill-stock, and having a curved arm, O, to press against and partly encircle the body E of the support.
NVhat I clain as my invention, and desire to secure by Letters Patent, is-
The combination of the extensible support described, the drill-stock having a stationary sleeve, L, and the sleeve N, adapted to encircle the sleeve L, and provided with the setscrew P and with the curved arm O, the latter adapted to partly encircle the said support, substantially as shown and described.
