Description
PATENT OEEIoEr J. F. DODGE, OF NEWARK, NEW JERSEY.
IMPROVEMENT IN WENCHES.
Specification forming part of Letters Patent No. 56,731, dated July 31, 1866.
To all whom it may concern:
Be it known that I, J. F. DODGE, of Newark, count-y of Essex, in the State of New Jersey, have invented a new and useful Improvement in Wrenches; and I do hereby declare that the following is afull and exact description thereof, reference being had to the accompanying drawing, making part of this specification.
My invention relates toanewimprovement in that class of Wrenches designated screw 7 or monkey wrenches; and has for its object to adapt this kind of wrench to use with any size six-square or hexagonal nut; and to this end my invention consists in cutting away a portion of each of the heels or back portions of the jaws of an ordinary screw-wrench in the manner hereinafter described, so that said portions of the jaws may be used with facility to turn six-square nuts.
To enable those skilled in the art to make and use my invention, I will proceed to describe it fully, referring by letters to the accompan ying drawings,in which is represented, in elevation, one `of my improved screw Wrenches.
In `the drawing, A represents the xed jaw, B the sliding jaw, O the screw shank, D clutch-nnt, andE the handle, of a screw-wrench made after the fashion of those now in use and well known to every mechanic, exceptthat iu lieu of having the heels or back ends of the jaws A B solid and square where they come together, (to use as a hammer only,) it has said portions cut out at 1 2, as clearly shown, so as to accommodate the sides and angles of a sixsquare nut, N, as seen.
The forward ends, c b', of the wrench-jaws, it will be seen, are made just the same as usual, as is all the rest of the wrench, so that my improvement and invention only necessitates the cutting away of the heels of the jaws, as seen at 1 2.
It is well known to every mechanic that, in
practice, it is generally necessary to have `the screw-wrench which is perfectly effectual for square-nuts will generally slip on the six squares and spoil the edges or angles of the nuts. By cutting out the heels of the jaws A B, as seen at l 2, on an obtuse angle recesses are formed to accommodate, and into which will precisely fit, the angles and sides of sixsquare nuts, as shown at N, in such manner that this kind of nut may be as eitectually grasped and turned (without danger of stripping the angles) as they can be by a forged wrench for the use of each nut and entirely surrounding the nut.
Of course my improvement is subject to modification to apply to eight-sided nuts, or any other polygon other than a square, the gist of my invention resting in the idea of so cutting out the heels or back ends of the jaws as to alford a receptacle, when such parts come together, for nuts having more than four sides and angles greater than eight angles.
It will be seen that enough of the stock of the hind portions of the jaws may be left to serve for the purposes of a hammer when the jaws are together, or even when apart.
Having explained myimprovement in screwwrenches, what I claim as new, and desire to secure by Letters Patent, is-
'Ihe double-jawed wrench, with one pair of the jaws cut away to fit hexagonal nuts, and otherwise constructed substantially as described.
In testimony whereof I have hereunto set my hand and seal this 2d day of May, 1866.
J. F. DODGE. [1.. s.]
In presence of J. N. MGINTIEE, WM. C. MGINTIRE.
