UNITED STATES i PATENT OFFICE.
p HENRY F. READ, OF BROOKLYN, NEV YORK.
IMPROVEMENT IN PIPE-WRENCHES.
' Specification forming part oi Letters Patent No. 35,950, (lated July 22, 1862.
v.'Zo all whom it may conceive:
Be it known that I, HENRY F. READ, ofthe city of Brooklyn, county of Kings, and State of New York, have invented a new and Improved PipeWVreuch for Screwing and Unserewing Metal Pipes;V and I do hereby de- Clare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. V
The nature of my invention consists in con structing pipe-wrencheswith a toothed eccen tric, to which is attached a chain and rod surrounded by a spiral spring, said spring being contained in a hollow handle. I construct pipe-wrenches with a jaw, to which is attached a'toothed eccentric by a permanent axis, in such a manner that-the turning of the toothed eccentric on its axis causes the teeth and jaw to accommodate themselves to different sizes of pipe.
t Figures l and 2 of the accompanying drawings are different views of the pipe-wrench complete. Fig. 3 is a longitudinal section of the pipe-wrench as represented in Fig. 2..
O is the handle, made of a piece of pipe, one end closed and the other end screwed into the body of the wrench A.
B is the eccentric, with teeth on a portion of its periphery.
e is the axis of the eccentric, on which it turns in the slot X.
D is a portion of a ring forming a handle to pull the eccentric from the jawg for the purpose of admitting the pipef.
m is a pin fixed to the eccentric, having a chain attached to its outer end. The other end of the chain is fastened to the end of a small rod, which passes through the body of the wrench, as shown in Fig. 3, and into the handle C. There is a spiral spring,i, around this rodfprovided with a shoulder against which one end of the spring presses, the other end pressing against a shoulder in the body.
The use ofthe spring and chain is to keep the eccentric pressed againsty the pipe.
I make the body of malleable or wrought iron, the handle of wrought-iron pipe, the spring and chain of brass or other suitable material, and the eccentric of tempered steel, all of such dimensions as the particular work for which .they are to be used requires. The eccentric is so constructed that the first or smallest size wrench will accommodate any pipe from one-fourth inch in diameter to one inch; the next size, all from one to two inches and a half, and so on.
The operation of the wrench is so simple as to be readily understood from the drawings without further'explanation.
I claim- In combination, the hollow handle O, spiral spring fi, chain l1, and eccentric B, substantially as described, and for the purpose set forth.
H. F. READ.
