FRANK C. WU'IKE, OF CHICAGO, ILLINOIS.

WRENCH.

T all whom 2'15 may concern:

Be it known that I, FRANK C. WUTKE,

citizenof the-United States, residing at Chicago, in the countyof Cook and State of Illinois, have invented certain new and useful Improvements in Nrenches, of which the following is a specification.

This invention relates to wrenches and has as its object to provide a wrench which may be conveniently employed even where a nut to be tightened or loosened is so located that it could not be readily engaged by a wrench of the ordinary type.

It is an aim of the invention to provide a wrench in which the handle may be connected to the stock so as to extend at various angles with respect thereto whereby to provide for convenient use of the wrench under various conditions, and one feature of the invention resides in the provision of means for holding the handle in its adjusted positions, which means may be readilymanipulated so as to provide for quick attachment and detachment of the handle to and from the stock.

For a full understanding of the invention reference is to be had to the following description and accompanying drawing in which Figure l isa view in side elevation of the I wrench embodying the present invention.

. in the other wall of the said recess.

Fig. 2 is an edge view, parts being shown in section. Fig. 3 is a sectional view on the line 33 of Fig. 2. Fig. a is a detail perspective view of the latch device provided for holding the handle connected with the stock.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

In the drawing the head of the wrench is indicated by the numeral 1 and is formed 01' provided with a fixed jaw 2. The movable jaw of the wrench is indicated at 3 and-has a shank 4 which is slidably fitted in a slot formed in the head 1. The shank 4: is proa recess 6 in its stock, which stock is indicated at 7, and a screw 8 is fitted through an opening 9 in one wall of the recess 6 and at its other end is threaded into an opening 10 11 is rotatably mounted upon the said screw atchet edge of the shank 4, of the movable Specification of Letters Patent. Application filed February 25, 1913.

A nut- Serial No. 750,686.

rotating the nut llthe movable jaw 3 may be adjusted with relation to a fixed jaw 2. Thestock 7 is provided with a squared portion 13 and this squared portion is formed with a rectangular opening 14: which at one end opens at the end of said portion 13 and at its other end opens .at the bottom wall of the recess 6 in the stock. The handle of the wrench is indicated at 15 and as illustrated has a relatively straight grip-portion 16 beyond which it is curved laterally. The handle terminates in a fiat end-face 17 from which projects a stud 18 which is rectangular in cross-section. Near its outer end the stud 18 is formed with a surrounding groove 19 and this groove is located at such a distance from the face 17, or the inner end of the stud that when the stud is inserted in the opening 14:, and the end of the portion 13 of the stock is in engagement against the end face 17 of the handle, the groove 19will register with the bottom wall of the recess 6. At this point it will be apparent that by disengaging the stud 18 from the opening let, the handle may be turned to assume positions at various angles to the plane of the head 1 and stock 7, and the stud again inserted in the opening 14 whereby to hold the handle atadjustment, and the present invention has as one of its objects to provide means for securely holding the stud 18 in. the opening 14 which means however, will be capable of ready manipulation to release the stud.

The means above mentioned, provided for Fatented Nov. 4, 1913.

body. It will of course be apparent thatby the purpose of holding the stud 18 in the opening 14, consists, briefly stated, in a latch member which is pivotally supported upon the screw 8 and has a portion arranged to engage in the. grooves 19 in the sides of the said stud 18. The latch member is 22 receiving the screw 8, and it will be 'observed from an inspection of the severalfigures of the drawing that when'the latchmember is assembled with the screw 8 the side portions 20 thereof will lie between the side walls of the recess 6 and the .corresponding ends of the. nut 11. It willilalso be apparent that the latch member swung upon the said screw 8 so'thatf oiie edge of its connecting portion :215rnay' be I 21 engaged in the groove 19, the side walls of the recess 6 are formed with relatively shallow depressions 23 and the side portions 20 of the latch member are formed with shallow protuberances 21 designed to engage in the depressions 23, it being understood that the latch member being formed from resilient sheet metal will have its side portions sprung inwardly as the protuberances ride over the side walls of the recess 6 and before they engage in the said depressions.

In order that the latch member may be swung into and outof position to lock the stud 18 in place, the connecting portion 21 isprovided with a finger-piece 25 which rests against the portion 13 of the stock when'the latch member is in engaged position.

Under some conditions, it may be found impractical to have the handle extend longi- "tudinally from the stock and in order that the handle may be connected or engaged with the stock so as to extend laterally therefrom, the grip-portion 16 is formed with an opening 26 which is rectangular and of a size to receive the squared.

ortion 13 of the stock.

From the foregoing it will be apparent that the wrench enibodvin the r ent invention may be conveniently employed even in cases where the nut to be engage A would be practically inaccessible in the use of the ordinary types of wrenches in which the handle permanently assumes a certain definite relation to the jaws of the wrench.

Having thus described the invention what is claimed as new is 1- 1. In a wrench, a stock having a socket,

a handle having a stud removably fitted and angularly adjustable in the said socket,

and a latch member having spaced side members pivotally supported upon the stock and a connecting portion, the stud having a oircumscribing groove and the latch member being mova'blg upon its pivot to position with-its connecting portion engaging in the groove in the studs.

2. In a wrenchlf a stock having a recess, the stock having a socket opening through one wall of the "recess, a handle havinga stud remo vably fitted in the socket and projecting at one en'd 'beyond the said wall of the recess, said stud having a groove in its projecting end-portion, and a latch-mom her having spaced portions and a connecting portion, the spaced portions being pivoted upon opposite walls of the recess and the said latch member being movable upon its pivot to position with its connecting portion engagingin the groove.

8. In a wrench, a stock having a recess, the stock having a socket opening through one wall of the recess, a handle having a stud removably fitted in the socket and projecting at one end beyond the said \vall of the recess, a stud having a groove in its projecting end-portion, and a latch-member having spaced portions and a connecting portion, the spaced portions being pivoted upon opposite walls of the recess and the said latch member being movable upon its pivot to position with its connecting portion engaging in the groove, the walls of the recess being provided with depressions and the spaced portions of the latch-members having protuberances arranged to seat in said depressions when the connecting portion of the latch-member is in engagement in the groove in the stud.

In testimony whereof I affix my signature in presence of two witnesses.
