,PIPE-WRENCH.
SPECIFICATION forming' part ,of Letters Patent No. 249,394, dated November 8, 1881.
Appncatiomea september 24,1881. (No model.)
To all whom 'it 'may concern Be it known that I, ISAAC B. POTTs,of Golumbus, in the county of Franklin and State of Ohio, have invented a new and Improvedl Pipe-Wrench, ofwhich the following is a full, clear, andeXact specication.
Reference. is to be had to the accompanying part of this specilication, in which similar letters of reference indicate cor-` responding parts iu all the igures.
Figure lis a side elevation of `my improved Fig.2 is a plan view of the same; and Fig. 3 is a cross-sectional elevation taken on the line w er of Fig. 1. y
A representsihe main bar, which is extended to form the handle b and bent down at the for- Ward end to form the fixed jaw ,aud is formed upon the under side with the notches c; and B represents the movablejaw, which is held under the main bar by means of the sliding saddle `or yoke C, which saddleor yoke is adapted to be raised or lowered by the set-screw d, for
engaging and disengaging the lip e, formed on the rear en d of the movable jaw, with and from the notches c of the main jaw.
'.ljheforward end orface,f, ofthe movablejaw is inclined from the top backward, and is formed with the downwardly-inclined teetl1.as shown in Fig. 1,While the main fixed jaw a is inclined in the opposite direction, and is formed with the teeth g, which are inclined upwardly, as also clearly shown in Fig. 1. By this opposite inclination of the faces of thejaws the bite of the tool upon the pipe or rod and its disengagenient therefrom are automatic, dependiu g solely upon -the up-and-down movement of the lever, thus dispensingwith all separate mechanism for that purpose and al1 necessity for griping any levers with the hands.
Having thus described my invention, .I claim y snew and desire to secure by Iietters Patent- The combination, with the bar A, provided with the inclined and serrated stationary jaw a at its outer end and the notches c on its under side, of the yoke or saddle C, the thumbscrew d, andthe movable jaw B, secured at each end to the said yoke or saddle, and provided with the lip c and the serrated i'acef, inclined in an opposite direction to that of jaw a, substantially as and for the purpose set forth.
ISAAC BROADWORTH POTTS.
