MARTIN GILLESPIE, OF SMITHS FERRY, PENNSYLVANIA.
IMPROVEMENT IN REAMERS FOR ENLARGllNC- OIL-WELLS.
Specification forming part of Letters Patent No. 141,344, dated July 29, 1373; application filed June 17, 1873.
. To all whom it may concern:
Be it known that I, MARTIN GILLEsPIE, ofv
y enlarging the bore of an oil or analogous well,
and in peculiar means for carrying out this method, as hereinafter fully described and subsequently pointed out in the claims.
In the drawing, B represents an oil-well whose bore it is desired to enlarge at any portion thereof. B is a Teaming-tool, having the cutter b and the inwardly-inclined centeringpin b', that works in a bearing, 0, of the tube (l. This tube is inwardly beveled at the upper and lower end, and may be recessed in the middle, so as to leave at each end only an annular flange that comes in immediate and frictional contact with the side of Well.
I lill the well with sand up to the highest point where the enlargement is ,to commence,
and th' n drop down thereinto the tubular bearing C. The tool is then let down, the journal b entering the tube C, and being thereby centered and guided in its rotary motion. The sand supports the centering-tube C, but, as the tool presses upon the latter, works up through the tube. The cavity'of this tube is preferably enlarged from the top toward the' bottom, so as to increase its capacity and facilitate the upward movement of the sand.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A reaming-tool having the cutter b and piu b', combined with a centering device that receives said pin.
2. A centeringdevice, C, for arearner, made tubular.
