J. VVILLANI WRENCH Filed Sept. 14, 1921 INVENTOR R O T A Patented Feb. 27, T9233.
entree stares JOHN VILLANI, F BROOKLYN, NEW YORK.
WRENCH.
Application filed September 14, 1921.
To all whom it may concern:
Be it known that 1, JOHN VILnANI, a citi- Zen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.
This invention has relation to wrenches, and has for an object to provide a wrench 0 having a stationary and a movable jaw and means for adjusting the one relative to the other with a view to disposing the handle to a greater or lesser distance from the center of rotation of the work so that the leverage required to rotate the work may be in proportion to the diameter of the work, the principle underlying the operation of the wrench being that the larger the diameter of the work the greater effort will be required to dislodge the work from its point of attachment.
Another object of the invention is to provide a wrench having the characteristics above set forth and embodying a jaw which is movable relative to the handle, a second jaw movable relative to the first aw, and a means to adjust said parts relative to each other to accomplish the objects set forth above.
0 In addition to the foregoing this invention comprehends improvements in the de' tails of construction and arrangement on parts to be hereinafter described and particularly set forth in the appended claims.
In the accompanying drawings in which similar and corresponding parts are designated by the same characters of reference throughout the several views in which they appear.
Figure l is a View in the side elevation of a. wrench constructed in accordance with my invention.
Figure 2 is a detail view in cross section taken on the line 2-2 of Figure 1; and
Figures 3 and 4: are similar views taken on the lines 3-3 and 4ll of Figure 1.
With reference to the drawings indicates the stationary jaw and 11 the shank formed therewith and which is rectangular in cross section. A cylindrical extension 12 is formed on the end of the shank and operates in a recess 13 formed in the handle 14:. The movable jaw 15 is formed with the opening 16 to receive the shank 11 and said aw is formed with a lateral enlargement 17 Ill Serial NO. 500,550.
terminating in the portion 18 which also embraces the shank. This construction of the movable jaw is conventional. A block 1-9 is provided having an opening 20 in which to receive the portion 12, said block abutting against the shoulder formed at the juncture of the shank and portion 12, a pin 21 being inserted through said block and. portion 12 to hold the parts together. A pair of spaced and apertured cars 22 are formed on said block and a threaded rod 23 is passed through said ears and anchored at one end to the enlargement 17 of the jaw 15 by means of a pin Qet. The other end of the rod enters a recess 25 in a lateral extension 26 of the handle, a pin 27 passing through said extension and rod, securely anchoring the latter in place. Previous to this assembly a knurled nut 28 is applied to the rod and located between the ears 22.
By rotating the nut the rod 28 and parts connected thereto are caused to move relative to the shank 11 and parts carried by the latter. As a result it will be seen that the more widely the jaws 10 and 15 are spaced the further the handle 14 will be located from a point midway of the faces of said jaws. As a rule the larger in diameter the nut or other work to be loosened or tightened, the greater is the effort required, and for that reason it has heretofore been necessary to employ a number of wrenches of different sizes. With this wrench any work may be rotated up to the limit of the jaw spacing since a necessary leverage required will always be aiforded by the wrench since the handle will always be located at the proper distance from the center of rotation of the work. Also, when the wrench is adjusted with the jaws in contact, the total length of the wrench will not exceed that of the conventional type of wrench. Other uses and advantages will be readily apparent to those familiar with the art to which this invention appertains.
lVhile I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended claims.
A Wrench including a stationary jaw, 21
5 shank formed therewith, a handle having a recess to receive the shank, a second jaw mounted on the shank, a threaded r0d secured at one end to the handle and at'its other end to said second jaw,
1 mounted on the shank,
a. keeper, and a nut mounted in said keeper for rotation and threadedly engaglng the rod to move said handle and seeond aw. 1n unison towardand away, from the stationary j aw.
In testimony whereof I afiix my signature in presence 0t." twoqv-itnesses.
