Description

N.PETERS. PHDTG'L-ITHOGRAPHER. WASHINGTON D C Ta `all whoml it 'may concern:
y ORANGE i o. LAwBAuea or sHANEsViLLE', onto.
Letters Patent N0. 107,790, dated september 27, 1870.
IMPRQvi-:MEN-r IN wRENcHEs.
The Schedulereferredto in these Letters Patent and making part of the same.
`Beit lknown that I, ORANGE C; LWBAUGH, of
Shanesville, in the county of rIuscarawas, andin the .State of'Ohio, have invented certain new and useful .i Improvelrnents in Wrenches; and do hereby declare 'that thefo1lowng is a full, clear, andeXact descri`ption thereof, reference being had to the accompanying drawing making a part of this speciication,in which-#-` `Figure l is aside elevation of my impro-ved device,
Figure is a rear `elevation of the same. v Letters of like name'and kindrefer to like parts in 1F" fetich of the figures' `My invention has for its object the production of a o cheap, convenient, and useful-tool for general farm or o householdrepair work; and to'thisend, f
o It consistsin 4combining a pair of pincers,.claw,
" hammer, and screw-driver with amonkey-wrench, substantially as hereinafter set forth.
In the annexed drawing t y Arepresents theshank of the wrench, secured to o or `uponrthe lower Yend of'fwhiclr is' a handle, B, of
usual construction, while upon its upper end is a fixed jaw, C, projecting outward, at a right angle with and v forming a partei' saidshank.' j
A'second jaw, D,- provided `with a `vert-icalslot ou t recess, correspondingin'iwidth to the thickness of the shank A, and extendingy tothe rear end of said jaw,
` is placed in position 4upon said shank, where it is loosely held inplace! by means ot"` a piu, E, passing horizontally through said jaw, immediately in` rear of the shank.v By this attachment the-adjustable jaw i may be readily moved, 'with the hand, to or upon thel ijxed jaw, but, upon placing theivreuch upon a nut, any
powercxerteduponathe handle, in turning said nut, will cause the forward end of said adjustable `jaw to r tipdownward,'until the lower side of thefl'ont end of the slot bears'agA inst one side of said shank, and the pin E against the opposite side, firmly clamping the `jaw in place. 0 i
As seen in fig. -1, the rear end of they, fixed jaw C lcurves outward and upward, and forms .one jaw, F,
U a `oi'fa pair of'pincers, theoppositejaw, G, of which is secured to and forms a part of a handle, H, that passyes downward through, and is pivoted within a suitable `slot provided in the rear end ot' said jaw G.
be drawn, `as with an ordinary claw, whilea horizontal projection, I, upon the outer side of saidV jaw, en-
ables the wrench to hensed as a hammer. y
In order that the movable jaw may be held in place while the position of the wrench is beiugchauged upon thenut, the` inner edge of the handle H-is provided with a series of transverse notchesor teeth, la,
which, when vsaid `handle is pressed against the handle V `of said wrench, engage witlrthe pin E,"and prevent said pin and the jaw D from moving.
K represents a short screw-driver, of usual form, having upon its lower enda round shank, k, which `fits into a corresponding opening passing vertically through the center of thejaw G. `A `horizontal groove proyided within thevupper side of the jaw 0,'having a dept-h of about one-eighth of an inch, anda width corresponding to the thickness of the sc1ewdri ver, receives lthe lower end of the latter, and secures its relative radial position within the wrench.
`The device is now complete, and, as it furnishes, within a small compass and at a comparatively small ',expcuse, five heretofore distinct and separate imple-` ments, it is believed that its advantages are so apparent as to insure its general use as' a household tool. p, Having thus fully set forth the naturefand merits of my invention,
That I claim as new, and desire to secure by Letters Patent,l is
The hereinbefore-describedinplement, consisting of a monkeyfwrench, pincers', claw, hammer, and screw- "driver, when constructed and arranged substantially as and for thepurpose specified. In testimony that I claim the foregoing, I have hereunto set my hand this 7th day of May, 1870.
Witnesses: ORANGE G. LAWBAUGH.
