UNITED STATES PATENTjoFFIcE.
ALBERT H. WOLFE, OF SANTA ROSA, CALIFORNIA.
WRENCH.
Application filed July 29, 1924. Serial No. 728,959.
To all whom it may concern:
Be it known that I, ALBERT H. WOLFE, a
citizen of the United states, residing at Santa Rosa. in the county of Sonoma and invention, such as will enable others skilled in the art to which it appertains to make and use the same. i
The invention relates to wrenches of the general type shown in Letters Patent granted to me on February 23, 1915, No. 1,129,- 771, and one object of the present application'is to cure certain imperfections of construction therein shown and to add certain parts omitted therefrom.
The main object of the invention is the provision of. av wrench comprised of two parts which shall be adapted for use in turning nuts of any shape in cross-se;tionsquare, polygonal, or roundand also as a pipe wrench.
A further object is to provide a wrench of the character mentioned which shall be adapted'to receive and turn nuts and pipes of different sizes withinlimits without the necessity of repeatedly adjusting the jaws.
The invention consists in certain novelties of construction and combinations of parts as herein set forth and claimed.
The accompanying drawing illustrates an example of the embodiment of the invention and improvements, the same being constructed and the parts combined according to the best mode of procedure I have so far dovised for the practical application of the principle.
Figure 1 is a plan view of the wrench as'it appears when innse to turn a nut. of any shape in cross-sectionround or polygonal; Fig. 2 is a similar view, showing the relative disposition of the parts when the wrench is used as a pipe wrench;
Fig. 3 is a plan view of the adjustable threaded double aw member removed from the stationary jaw member and the fulcrum and nut-supp0rting sleeve; and
Fig. 4c is a plan view of the fulcrum and nut-supporting sleeve detached.
The main parts of the wrench are: a stationary jaw and rigid extension or handle, an adjustable double jaw member having a threadedshank, a fulcrum and nut-supporting sleeve, and an adjusting nut.
The first-mentioned member has a aw A with a plain gripping surface 1 and a serrated surface 2, which surfaces may be disposed in planes at a slight oblique angle to each' other, asshown. A rigid extension B at right angles to the jaw A constitutes a handle. Through the center of thejaw 1S a hole or perforation rectangular in crosssection, the opening at the bottom being.
wider than at the top, as the surfaces at 3 and A are in different planes, so the shank of the double aw member may rocln At; the under surface of the jaw is a fulcrum hearing 5.
The adjustable double jaw member has two jaws C and D, the surface at 6 beingv plain and that at 7 being serrated. A shank E rectan ular in cross-section extends'from the jaws at a right angle, and the lower part thereof is rounded and provided with' screw-threads 8, as shown.
The fulcrumand nut-supp0rt1ng sleeve F,
shown bv Fig. 4, is of the shape illustrated by the full and dotted lines, the latter designating a hole of perforation 9 extending longitudinally through the same, and at, the
center is an open space 10 to' receivea threaded. nut-G which receives the threads 8 of the shank E, aSis obvious. At thepoint ll isa fulcrum hearing which. matches the fulcrum bearing at the under surface of jaw A. It will be observed that when the nartsarc assembled these fulcrum bearings are located at one side of the actual line of the threaded shank E. The lower end of the sleeve F extends, as shown, below-the-nut G and outside ofthe end of the shank of the double-j aw member; and thus this'sleeve end acts as a protection or sheath for this normally holds the parts as shown in Fig.
1, and when the wrench is used as a pipe wrench the spring holds the jaws in contact with the pipe, as shown by Fig. 2.
The pin 12 holds the shank E and jaws the nut is turned to move the shank E and double jaw outwardly.
It will be observed that the openings between the jaws for the nut and the pipe when the wrench is used for either purpose are slightly wider at the open ends than farther back, which facilitates the entrance of the nut or pipe to the extent desired. In Fig. 1 the serrated surfaces of the jaws are parallel, and in Fig 2 the plain surfaces of the jaws are parallel.
The ways of using the wrench and its mode of operation in gripping a nut or pipe will be understood and appreciated by those familiar with the art..
That I claim is:
1. The combination in a wrench, of a perforated stationary jaw and rigid handle, an adjustable double jaw member having a shank normally located within the perforation in the stationary aw and the lower end of'the shank threaded, a nut on the threaded shank, and means independent of the stationary jaw holding the nut so it cannot move when turned to raise and lower the shank and double jaw; the perforation in the stationary jaw being so shaped that the double jaw and threaded shank member can rock relative to the stationary jaw.
2. The combination in a wrench, of a perforated stationary jaw and rigid handle, an
adjustable double jaw member having a I shank normally located within the perforation in the stationary jaw and the lower end of the shank threaded, a nut on the threaded shank, and means between the nut and stationary jaw to hold the nut so it cannot move relative to the stationary jaw when moving the double aw and shank member outwardly; the perforation in the stationary jaw being so shaped that the double jaw and threaded shank member can rock relative to the stationary aw.
3. The combination in a wrench, of a perforated stationary jaw and handle, an
adjustable double aw member having a shank movably located within the perforation in'the stationary jaw and the lower end of the shank threaded, a; nut on the threaded shank, and a sleeve also on said shank between the nut and the stationary jaw; the perforation in the stationary jaw being so shaped that the double jaw and threaded shank member can rock relative to the stationary jaw.
at. The subjectanatter of claim 3, with the addition of a pin between'the handle and sleeve fixed to one of them and loosely engaging the other said pin being independent of the stationary jaw to hold the sleeve so it cannot move longitudinally relative to the handle.
The subject-matter of claim 3, with the addition of a spring 14: secured to the handle and the free end loosely seated within a recess in the sleeve.
6. The subject-matter of claim 3, with a fulcrum bearing between the sleeve and the lower surface of the stationary jaw.
7. The subject-matter of claim 3, with a fulcrum bearing between the sleeve and lower surface of the stationary jaw, said bearing being at one side of the longitudinal axis of the shank of the double jaw and shank member.
8. The subject-matter of claim 3, when the gripping surfaces of the stationary jaw and the gripping surfaces of the doublejaw are so disposed to each other that the two gripping surfaces of opposite adjacent jaws will lie in planes oblique to each other.
9. The subject-matter of claim 3, when the gripping surfaces of one of the j'awsare in the same plane and the gripping surfaces of the other jaw are in planes oblique to each other.
10; The subject-matter of claim 3, when the sleeve is provided with an opening to receive the adjusting nut and the end is extended below the nut outside the threaded shank of the double aw and shank member.
ll. The subject-matter of claim 3, when two of the adjacent gripping surfaces of the stationary jaw and double jaw are serrated, and when the wrench is used as a pipe wrench located in planes oblique to each other.
In testimony whereof I afix my signature.
ALBERT H. WOLFE.
