CHARLES M. LAMBERT, OF DARKE COUNTY, OHIO, ASSIGNOR OF ONEHALF TO EDVARD C. TRITT, OF UNION CITY, INDIANA.

WRENCH.-

SPECIFICATION forming part of Letters Patent No. 712,552, dated November 4, 1902.

Application filed January 14,1902. Serial No. 39.757. .110 model.)

in all whom it may concern.-

Be it known that I, CHARLES M. LAMBERT, a citizen of the United States, residing in the county of Darke and State of Ohio, have invented new and useful Improvements in Wrenches, of which the following is a specification.

My invention relates to improvements in wrenches and analogous tools; and it consists in the peculiar construction, novel combinations, and adaptation of parts hereinafter described and claimed,

In the accompanying drawings, Figure l is a side elevation of the tool with the movable member of the wire-cutter in a position to permit of the placing of a wire in the notch of the complementary member of said cutter; Fig. 2, a view, partly in side elevation and partly in section, with the movable member of the Wire-cutter in alinement with the handle and the forward end of the combined rack and screw-driver bar extended, beyond the fixed forward member or headof the nut and pipe wrench and vise; Fig. 3, an enlarged transverse section taken in the plane indicated by the line 3 3 of Fig. 2; Fig. 4, a detail plan of the handle portionof'the tool, and Fig. 5 a detail View of the forward end of the tool with a portion of the fixed wrench 30. and vise member orhead broken away.

Referring by letter to the said drawings, A is a handle, B a shank, and O a fixed wrench and vise member, which .in the preferred embodiment of the invention are formed inte- 3 5 gral and constitute the body of the tool. Said member 0 is provided at one side of the shank with claws a, which constitute a nail-puller and part of the pipe wrench and vise, and its portion b at the opposite side of the shank 40 has a fiat inner face a, and hence'is adapted to form part of the nut-wrench.

D is a longitudinally-adjustable bar ar:

ranged alongside the shank B and in guides (Z c of the handle A and wrench member C,

5 respectively, and having rack-teeth f and a beveled forward end g, wherebyit is adapted to serve for the engagement of the detent of' the adjustable wrench and vise member or jaw and also as a screw-driver, and E is the said adjustable vise and wrench member.

Thismember has a recess h in one side to receive the shank B and bar D, and a portion 72. of said recess is of dovetail form in crosssection to accommodate the corresponding part 71 of the shank, Fig. 3Q By virtue of this construction it will be observed that when the member E is on the shank in advance of the rear end of the dovetail portion 1' thereof it will be securely held against lateral movement off the shank; also, that when the member E is moved to a position in rear of the rear end of the dovetail portion 15 it may be readily moved in a lateral direction off the shank and the bar D, this to render the tool light when it is desired to use the same simply as a screw-driver, a nail-puller, or a wire-cutter. The member E is'further provided with a fiat-faced portionj at one side of the shank,

the member E inthe position desired to engage and hold a nut or pipe.

The handle A is provided in its upper edge at a point adjacent to its forward end with a notch 72 to receive a wire, and at said forward end it has a lateral-portion p, in which the guidaaperture d is formed. Saidportion p terminates in" a rearwardly-extending arm q,

between which and the main portion of the handle is pivotally connected the movable member F of the wire-cutter. This member F has a cutting or shear] edge 0", a cam portion 3, and a shoulder t, Fig. 2. When a piece of wire is placed in the notch n of handle A, which constitutes one member of the wire-cutter, and the member F is moved from the position shown in Fig. l to that shown in Fig. 2, the edge r will obviously operate to cut the wire. The cam portion 5 operates to move the bar D forwardly when the member F is moved as stated, and thereby extends the end g of said bar beyond the forward side of the member 0, and it also serves to hold the said bar D against casual backward movement incident to the use of the implement as a wrench or a vise. The shoulder q serves by engaging the bar D to limit the movement of member F when the same is swung down into the position shown in Fig. 1. In using the improved tool as a wrench the jaw E is first adjusted against the article to be turned, after which the member F is moved into the position shown in Fig. 2. When this is done, it will be observed that the jaw or member E will be tightened and securely held against the article, with the result that liability of the same slipping is reduced to a minimum. When it is desired to use the tool as a nail-puller, the memberF is moved down into the position shown in Fig. 1 and the bar D is pushed back so that its beveled end g will be sheathed in and protected by the wrench member or head 0.

It will be readily appreciated from the foregoing that notwithstanding the many purposes which it is adapted to serve my improved tool is no more cumbersome than an ordinary monkey-wrench and but little more costly.

I have entered into a detailed description of the construction and relative arrangement of parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however,

to be understood as confining myself to such specific construction and relative arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my invention.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In atool, the combination of abody made up of a handle, a fixed wrench member or head, and a shank interposed between said handle and wrench member or head, and having the forward portion 1' ot comparatively large size in cross-section; of a longitudinally-movable,toothed barguided in the body, a wrench member or jaw movable on and removable from the shank and toothed bar and equipped with means for engaging the latter; said member or jaw havinga recess in one side receiving the shank and toothed bar and provided with an enlarged portion receiving the enlarged portion of the shank, and a movable member connected to the handle and having a portion arranged to engage the toothed bar and move the same forwardly, and hold it against casual rearward movement.

2. In a tool, the combination of a body made up of a handle, a fixed wrench member or head, and a shank interposed between said handle and wrench memberor head; ota longitudinally-movable, toothed bar guided in the body, a wrench member or jaw movable on the shank and toothed bar and equipped with means for engaging the latter, and a movable member connected to the handle and having a portion arranged to engage the longitudinally movable bar and move the same forwardly and hold it against casual rearward movement.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

CHARLES M. LAMBERT.
