Description
iiaitrd gatita geteilt @wird Letters Patent No. 93,824, dated August 17, 1869. y
IMPRQVED coMPoUND Toor. oRWA'rER Nb GAs-PIPBS The Schedule refened to in these Letters Patent and making part of the same.
Be it known that l, WILLIAM HUMPHREYS, of
Waterford, Saratoga county, State of New York, have V invented av new and useful machine, denominatedY a Combined Drill, Reamer, and Tap; and I do hereby declare that the following is a ti1ll,clear,aud exact description of the construction and 'operation of the saine, reference being had to thc annexed drawings,
making a partof this specification, in whicl1- Figure l is a perspective Iview, Abeing the tap, with the combined reamer, shown' at B, and the drill at O.
The nature of my invention consists irrproviding the lower end of any ordinary tap with au extension gradually tapered, and formed intoa reamer,\'vith the extremity fashioned with the cutting-edges of an ordinary drill. l
By reference to the drawing, it is plain to be seen that the instrument is a combination of drill, reamer, and tap, and is more especially adapted to tapping gas,'water, and steam-pipes, which has the advantage ot doing away with numbers ot' tools usedforthe purposes aforesaid. It lessensthe number at least one,
and oftentimes two or more.
rlhe other advantages ot' this invention are, that the tap goes straight to its work, being held and balanced in proper position by the yreamer part, without any wabbling, to which ordinary taps are subject. It also keeps the drill rm while cutting through the in neror recedrag side o f the pipe, vand prevents the drill slipping through and leaving an irregular or ragged in'uer edge to the hole, which ordinary drills are liable to.
Another advantage claimed, is the prevention of the escape of gas to any extent, when pert'oratingv the gas-pipes and mains, as is the ease ordinarily, where two-or three separate tools are used.
This instrument may be used fwith the ordinary ratchet-brace, lathe, or otherwise.
lhe tool may be made so as to `en1body only the drill and rentner-,orthe dlill and tap, or the reamer and-tap.
Having thus described my invention,
I claim a combined drill, reamer, and tap, of the form and construction herein setforth.
\V1LLIAM HUMPHREYS.
