FRANKLIN WILLIAM FRI'ICI-IEY, OF SANDUSKY, OHIO.
WRENCH.
Specification of Letters Patent.
Application filed January 18, 1911.
Patented Sept. 12, 1911.
Serial No. 603,242;
To all whom it may concern:
Be it known that I, FRANKLIN W. FRITCHEY, a citizen of the United States, and a resident of Sandusky, inthe county of Erie and State of Ohio, have invented a new and Improved Wrench, of which the following is a full, clear, and exact description.
My invent-ion is a new and improved wrench having a fixed jaw and a movable jaw, the movable jaw being so connected to the handle that when the latter is pulled to turn a pipe, rod or other contrivance, the act of pulling not only exerts a leverage on the handle but also exerts a leverage action on the pivoted end of the movable jaw, causing the hold of the wrench to be tightened.
Reference is to be had to the accompanying drawings forming a part of this speci fication, in which similar characters of reference indicate corresponding parts in both the views.
Figure 1 is a side elevation of my improved wrench; and Fig. 2 is a rear elevation thereof.
My improved wrench consists of a handle 1 having two flat surfaces 2 at its end, and a lateral projection 3 of somewhat greater thickness than the end bearing the Hat surfaces 2. One edge of the projection 3 carries jaw teeth 4, and the adjacent end of the handle 1 carries a segment of gear teeth 5. These teeth are arranged on intersecting arcs, as shown, and the projection 3 forms the fixed jaw of my improved wrench.
The end of the wrench carries a pivot 6, on which are mounted two links 7 the lower ends of which engage the flat sides 2. The pivot 6 has hemispherical heads on its opposite ends to keep the links in place. These links are pivotally connected at their oppo site ends to a movable jaw 8, which has a reduced flat shank 9 having an opening therein to correspond with the openings in the adjacent ends of the links to receive a pivot bolt 10, similar to the pivot bolt 6. The outer edge 8 of this movable jaw is curved, as shown. The inner edge presents two surfaces at right-angles to each other, these surfaces carrying engaging aw teeth 11 and 22. The shank 9 terminates in a segment of gear teeth 13, which engages with the gear teeth 5 of the handle 1. A
pipe 14: is shown in dotted lines between the jaw teeth 4: and the teeth on the inner side of the movable jaw, illustrating the manner in which the wrench operates.
To use the wrench, the movable jaw is placed over a pipe, rod or the like, and the same is then engaged by the teeth 4:, 11 and 12. When the handle is pulled to turn the pipe or rod, the turning force acts partly on the pipe 14 as a pivot to turn the same, and partly on the bolt 6 as a pivot to exert a leverage action on the movable jaw 8, causing the same to grip the pipe It more firmly. For example, if the handle 8 be pulled to the left on Fig. 1, the segment of gear teeth 13 on the end of the shank 9 will be caused to turn to the right. This will cause the jaw 8 to move closer to the fixed jaw 8. The more the handle 1 is pulled to the left the tighter will the pipe 14: be gripped between the jaw teeth 1 and the movable jaw 8, and all slipping between the wrench and the thing upon which it acts will be obviated. At the same time the full turning force will be exerted upon the pipe or rod, or other article on which the wrench is being used.
It will be observed that my wrench is simple in its construction and efficient in action. It can be cheaply manufactured and is well adapted for all the purposes to which tools of this description are applied.
1 may obviously make such changes in the shape and size of the parts as clearly fall within the scope of my invention.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
1. A wrench comprising a handle having gear teeth on its end, a movable jaw, links pivotally connecting the movable jaw to the handle, gear teeth on the said jaw adjacent the links, and means carried by the jaw and the handle for engaging a pipe, rod or other article to be turned.
2. A wrench comprising a handle having gear teeth on its end, a movable jaw, links connecting the said movable aw to the handle, gear teeth on the end of said movable jaw adjacent said links, said gear teeth engaging the gear teeth on the handle, and a lateral projection carried by the handle forming a fixed aw in position to cooperate with the movable jaw.
3. A wrench comprising a handle having gear teeth on its end, a movable jaw, links pivotally connecting the said movable jaw to the handle, gear teeth on the end of said jaw adjacent said links, engaging the gear teeth on the handle, a toothed projection carried by the handle, forming a fixed jaw, and teeth onthe movable aw adjacent the jaw teeth on the handle.
4: A wrench comprising a handle having gear teeth on its end, a movable jaw pivotally connected'to the handle and having geanteeth engaging the gear teeth on the han dle anola: projection carried by the handle, forming a fixed jaw to cooperate with i the movable jaw.
5. A wrench comprising a handle having gear teeth on its end, a movable aw, a link pivotally connecting the movable jaw t0 the handle, gear teeth on the said jaw adjacent the link, to engage the gear teeth on the handle, and means carried by the jaw and the handle for engaging a pipe, rod or other article to be turned.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
