APPLICATION FILED JAN. 12, 1910.
969,189. Patented Sept. 6,1910.
men s'rnras mama orator;
rmk a. nnnnmnonan, or roars, NEW roared To all whom'it may concern:
Be it known that I, FRANK. A. RADE- MACHER, a citizen of the United States, residing at Forks, in the county of Erie and State of New York, have invented a new and useful Improvement in Wrenches, of which the following is a specification.
This invention relates to a wrench which is more particularly designed for turning pipes although the; same may also be used for turning screw nuts and other purposes.
'The object of this invention is the production of a wrench of this character which is simple and durable in construction and which permits a firm grip to be obtained on the article to be held with the application of a small amount of power. I
In the accompanying drawings: Figure 1 is a side elevation of my improved wrench. Fi 2 is a top plan view thereof.
{similar letters of reference indicate .corresponding parts in both figures. I
In its general organization my improved wrenchresembles aqair of tongs and comprises a pair of hand evers A, B which cross each other near their front ends and are adapted'to be grasped at their rear ends by theha'nd of the operator. At its front end the hand lever B is provided with a front jaw a which projects laterally toward the front side of the wrench and which has a grippin face 0 arranged substantially at -ri ht ang es to ,the longitudinal rear part of th1s lever, said gripping face being on the rear side of the jaw a. At the base of the jaw c the lever B is provided with an offset portion (2 which projects laterally toward the rear side of the wrench and which forms a recess or pocket d on the front longitudinal side of this portion of the lever B. The other hand lever A is provided at its front end with a jaw s which projects laterally toward the front side of the wrench and has a gripping face e arranged at an oblique a e to this hand lever. and turned toward 1: e front end of the wrench so as to standlopposite the face of the front jaw c. The faces of the jaw may be either plain or toothed but as shown in the drawings the front w is plain while the rear jaw is 'toothe' In rear of its jaw e the hand lever A is-provided with an off-set portion j which projects laterally toward the front side of the wrench thereby formin a pocket or recess f lever.
on the rear longitu inal side-of this Specification of lietters Patent. ywl nfi ed Sept 6, 191g, Application filed January .1 2, 1910. Serial No. 537,749.
The two hand levers A, B are pivotally the levers and preferably consists of two sections G arranged on opposite sides of the frontends of the-hand levers. At one end this link is pivoted to the lever B at the" front end of its off-set portion by means of i A I a transverse rivet h, as shown, or any other sultable connection while the opposite, end
thereof is pivoted to the front end of the other lever A by means of a transverse bolt a, as shown, or other approved connection.
When using the wrench the rear ends of its hand levers are swung apart thereby separating the jaws of the same and permitting of introducing the pipe or other article different points of its periphery and at the same time press the pipe into' the V-shaped spaces between the link and the front and rear jaws, whereby a powerful hold is obtained on the pipe and the same is compelled to turn with the wrench. In order to permit of adjusting the wrench so as to ada t the same to articles varying greatly in slze the link G is provided with a long1- tudinal row of openmgsvj and the oif-set part of the hand lever A is provided With a curved row of openings is into one or the other of which the bolt i may be shifted to suit the size of the pipe, nut or other article to be grasped and turned.
By off-setting the hand lever B adjacent .to the rear jaw a space is provided which receives the article to be grasped and per- .mits the wrench to properly embrace said articleand obtain an effective grip thereon.
The off-set in the lever A permits of arranging the openings 70 in a curved line.
which permits of'more readily adapting the wrench to articles varying largely in size and still cause this part of the hand lever A to be of substantially the same width as the adjacent parts of this hand lever.
I claim as my invention: 1. A wrench comprising a pair of hand levers which cross each other but are disconnected at the crossing between the same,
one of said levers being provided at its front end with a front j aw and the other lever being provided at its front end with a rear jaw which opposes the front jaw, and a link connected by fixed pivots with said levers in rear of said jaws.
2. A wrench-comprising a pair of hand levers which cross each other but are disconnected at the crossing between the same, one of said levers being provided at its front end with a front. 'aw and the other lever being rovided at 1ts frontend with a rear jaw w ichopposes the front jaw and a link connected by fixed pivots with said levers between their jaws and the crossing thereof.
3. A wrench comprising a pair of hand levers which cross each other but are disconnected at the crossing between the same,
sides of the levers. v
- V coarse 4. A wrench comprising a pair of hand levers which cross each other, one of said levers having a front jaw at its front end and an outwardly off-set portion adjacent to said j aw, and the other lever having a rear jaw at its front endwhich opposes said front j aw and an outwardly off-set portion adjacent to said rear jaw, and a link connecting the off-set portions of said levers.
5. A wrench comprising a pair of hand levers which cross each other but are disconnected at the crossing between the same, one of said levers having a front jaw and the other a rear jaw, and. a link connected by fixed pivots with said levers and composedof two sections arranged on opposite Witness my hand this 21st day of December, 1909.
