Patented m, i2, 1932 UNITED STATES PATENT OFFICE WRENCH Application filed January 28, 1929. Serialjlo. 385,586.
My invention relates to improvements in wrenches and it consists in the combinations, constructions and arrangements hereinafter described and claimed.
An object of m invention is to provide a wrench that can he used as a pipe wrench, monkey wrench, or pliers. One of the lprincipal features is the provision of a jaw aving a cam-shaped edge, this edge cooperating with the edge of a second jaw so that the wrench will have a tendency to bind more tightly upon the nut or other object which it engages as more pressure is applied to the wrench for rotating the nut. It is not necessary to more firmly grip the two handles of the wrench as greater force is used for moving the nut, as is the case with the usual pliers. The cam edge will automatically cause the handles to tend to swing together as more force is applied in turning the nut.
A further object of my invention is to provide a device of the type described which is extremely simple in construction and in which the jaws are designed to accommodate nuts of various sizes and shapes. The wrench also makes use of a quick-moving feature for rapidly moving the jaw when the handles are slightly moved.
Other objects and advantages are shown in the following specification, and the novel features will be particularly pointed out in the appended claims.
My invention is illustrated in the accompanying drawing, in which Figure 1 is a plan view of the wrench;
Figure 2 is a plan view of a wrench showing the same type of jaws but illustrating a mechanism for quickly moving one of the jaws; and
Figure 3 is a section along the line 3-3 of Figure 1.
In carrying out my invention, I provide a wrench that has two handles 1 and 2 pivoted together at 3. The handle 1 has a jaw 4 which is provided with a cam-shaped edge 5 and a shoulder 6.
In addition to this, I show in Figures 1 and 3 a groove 6' that extends longitudinally of the face 7 of the jaw 4. This groove merges into a transversely-extending groove 8.
The handle 2 carries a jaw 9, and this jaw has a flat surface 10 and a second surface or edge 11 that extends at an angle with respect to the first. The workin edges 10 and 11 on the jaw 9 are re-entran y inclined with respect to each other. In this second edge I provide a V-shaped cut 12. This cut may be dispensed with if desired without departing from the spirit and scope of the invention.
From the foregoing description of the various parts of the device, the operation thereof may be readily understood.
In normal position the edges 7 and 10 abut each other. These edges permit the wrench to he used as a pair of pliers, and the grooves 6 and 8 are designed for the purpose of receiving cotter pins and the like.
In Figure 1, I show the jaws 4 and 9 as being moved slightly apart for receiving a square nut 13. The edge 10 engages with one side of the nut, while the cam edge 5 engages with the opposite side. The wrench is swung in a clockwise direction for tightening the nut, and it will be seen that the cam edge 5 will have a tendency to swing the handles 1 and 2 toward each other during this movement. This will relieve the operator of having to grasp the handles more firmly as greater force is applied upon the nut 13. The cam edge 5 is so designed as to cause the wrench to accommodate itself to nuts of various sizes. The nut 13 contacts with the cam edge 5 at thepointX. Thelargernutwouldcontactwith the edge 5 at a point nearer the pivot point 3 of the wrench. In this way the wrench will as effectively grip various sized nuts.
In Figure 2, I show the same type of jaws 4 and 9, and therefore like reference numerals will be applied to these jaws. This figure shows the V-shaped recess 12 as receiving a part ofa hexagonal nut 14. It will also be noted that the nut 14 contacts with the jcam edge 5 at a point further in. 4
Figure 2 also shows a mechanism for qhickly moving the jaw 9. A handle 15 is substituted for the handle 2, and this handle is connected to the jaw 9 by a link 16. The handle is pivoted to the jaw 4 at 17. A second opening 18 is provided at 18 if desired. The jaw 9 .s pivoted to the handle 1 at 19, this taking the place of the bolt 3.
It will be seen from this construction that a slight movement of the handle 15 toward and away from the handle 1 will rapidly swing the jaw 9. In all other respects the two wrenches shown in Figures 1 and 2 are identical..
Although I have shown and described several forms of my invention, it is to be understood that the same is susceptible of various changes, and I reserve the right to employ such changes as may come within the scope of the invention as claimed.
I claim:
1. A wrench having two jaws pivoted together, one of said jaws havin straight nut gripping edges re-entrantly inc 'ned with respect to each other, and the other jaw having a curved or cam edge, with an abutment at the outer edge of said cam, said abutment contacting the other jaw when in closed position.
2. A wrench having two jaws pivoted together, one of said jaws having straight nut gripping edges, re-entrantly inclined with respect to each other, and the other jaw having a curved or cam edge, with an abutment at the outer edge of said cam.
3. A wrench having two jaws, one of said jaws having a sharply convex working edge with an abutment at the outer end of the edge, the other jaw having straight working edges re-entrantly inclined, the inclined straight edges substantially paralleling the convex edge when the jaws are in closed position.
4. Awrench havingtwo solid jaws throughout their entire working edges, said 'aws being pivoted together and having han les that do not pass each other in any position of the jaws, the working edge of one jaw being in g the shape of a convex cam, the other jaw hav ing edges re-entrantly inclined.

9 .s pivoted to the handle 1 at 19, this taking the place of the bolt 3.
