Application sled Pecember 1,1892. Serial Nc.4 3,'772- (No model.) Y
To all whom/it malt/concern:
Beit known that I, EDGAR A. HUMPHREY,
siding at Columbus, in the county of Warren and State of Pennsylvania, have inventedcertain new and useful Improvements in Wrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will" enable others skilled in the. art to which it appertains to make and use the same, reference being had to .the accompanying drawings, and to letters of reference marked thereon, which form :a, part of this specification.
This invention relates to improvements in wrenches, the object of the same being to provide means for forcing the movable jaw of the wrench against the stationary jaw after said movable jaw has been adjusted by the adjusting-nut which engages with the shank to which the stationary jaw is secured and the invention consists in the construction and combination of the parts, as will be hereinafter fully set forth, and particularly pointed out inthe claim. I
In the accompanying drawings, forming part of this specification: Figure l is aside elevation showing, in full lines, the jaws clasping an object and in dotted lines as released therefrom. Fig. 2 is a sectional View on the line 00-00 of Fig. 1'.
A designates the stationary jaw to which the shank A is rigidly attached, said shank passing through the handle to which it is attached by a nut as'shown. The stationary jaw is provided on one side of the shank with a fiat face a adapted to engage a nut, while on the other side of the shank the jaw is exhaving dove-tailed recesses in which are secured steel bits for grasping a pipe or tube.
constructed similar to those of the stationary jaw, and by providing these faces the wrench can be used upon either a nut or pipe.
The movable jaw, 13, is provided centrally with an aperture through which the shank passes, and on one side of said jaw are formed ears Ii between which is pivoted alever O, and
by means of a-short link E. The slide engages with the adj usting-nut F, said nut having an aperture threaded to engage with the threads on the shank of the wrench. The link E is bifurcated at its end which is pivoted to the lever, and at its other end is' a projecting portion adjacent to which is formed shoulders which are adapted to bear upon the slide D, and the lever is so constructed that when. the free end thereof is moved toward the shank or handle of the wrench to its fullest extent it will bear upon the projection d, and when in this position the pin which connects the link with the lever will be located .on the inside of a line connecting the pivot pin in the jaw and the main the slide; thus locking thelever. The shank A is provided with flat sides which will prevent the jaw 13 turning thereon, and the movable slide D is apertured to engage with the flat sides of the shank so that it is kept in line with the jaw B. The nut F has a portion which is embraced by the slide 1), so that when the nut is turned the slide will be adjusted upon the shank and will carry with it themovable jaw. The lower end ofthe movable jaw is provided witha fiat face, and the face of the ver is thrown outwardly, as shown in dotted lines, the slide 1) and jaw B will bear against each other, and they are usually placed in great range of adjustment, as the jaw is then not liable to clamp upon the shankwVVith this construction I may dispense with extra slides or guides.
By this device the mova justed to the proper distance to grasp a nut or a pipe, and when it is desired to release the wrench it is only necessary to move the lever away from the shank or handle; or if desired the adjustment can be made and the lever employed for forcing the movable jaw toward the stationary jaw and upon the obje to be grasped I am axare that it has been proposed to "provide a w ranch with a movable slide which can be ad justed upon the shank, the slide carsaid lever is connected to a movable slide .D
rying a toggle which is connected with a lever, said lever also providing means for conslide is similarly shaped so'that when the lethis position when it is. desired to make a ble jaw can be ad- 7 necting the movable jzui' totho or toggle sli'flo, and I do not therefore claim such construe i-ion broadly; but
What I do claiiin as new, and (lesii'e to seom-o by Letters Patent, is-
A combined pipe and nut wrench, consisting of :1 handle her having at one end. jaw which egtend on opposite siolosof the honsegmental screw-threads, a yoke-[mine D which is adapted to engage with a nut F, the yoke-frame having" projecting portions hetweon which is pivoted a link the upper and 0i which i." bifurcated, a sliding-jaw l3 havingn face similar to the face of the jaw A and a recess in which it lovor G in pivoted,
mid lover having a projecting portionlo which the bifnmitedenrl of tilfl llllli E 13 pml'JiGli, the parts being organized substantially In testimony \vhoreoll :i (ll); my signature in I prose-nee of two Witnesses.
