Application filed March 27,1919, Serial No. 285,600. Renewed. February 8, 1921. Serial No. 443,491;

T 0 allwhom z't may concern Be it known that I, CHARLns A DIES, a citizen of-the-United States of America and a resident of Chicago, in the county ofook, State of Illinois, have-inventedjcertain new and useful Improvements in Wrenches and the like, 'of which the following is aspecification. This invention relates to adjustable wrenches and like implements, and more especially to that type of the same in which a manual 'stresson the handle forces, the pivoted jaw members against the article or work, an example of which forms the subject matter of my prior Patent N 0. 1,155,136, dated September 28, 1918. And the present improvement has for. its various objects To provide a simple 'and] efiicient structural formation and combination of a. guide housing and-associated parts adapted toafford a durable, strong and economical construction. i V H e To provide a simple and durable formation and association ofv parts whereby the adjusting screw sleeve of the implement is yieldingly held to place, and loose motion between the jaws prevented in a convenient and effective manner. j

' In the accompanying drawings Figure ,1 is a side elevation of a pipe present improvement applied. I i

Fig. 2 is an enlarged fragmentary longi;

tudinal sectional'elevation of the same. 4 Fig. 2", is a detail elevation of the holding spring of the adjusting screw sleeve ofthe implement. 0

Fig. '3 1s a transverse sectional elevation blank from which the im lement is formed.

ike reference numerals indicate like parts in the several views.

Referring to the drawings, 1 designates the guide housing of an approximately rectangular shell form and having the detail structural formation hereinafter more fully described.

2 designates the adjustable member of the implement having a screw-threaded shank guide housing of the 3 of the usual rectangular or other non-circular form in cross-section and arranged for V sliding movement in the guide housing 1 7 guide housing aforesaid. At its forward end the member 2 is formed with an angularly disposed jaw 4, the detail structure of which may vary to suit the different uses to which the implement is' applied. 'It being the intention to provide a plurality of such adjustable heads, interchangeable one with the other, and each having the required detail construction adapting it for a particular use.

' 5 designates an adjusting, sleeve formed for convenient rotation by hand, and arranged in a recess formed in the mid-length ofthe upper portion of the guidehousing 1 Jason, or CHICAGO,

as shown, and with its bore formed with screw-threads for operative engagement with the screw-threaded shank 3 of the adjustable member 2 of the implement;

6 designates the companion aw of the implement pivotally mounted at its upper end in the guide housing 1 by a transverse pivot pin 7, adapting it. for limited movement toward the other j aw 4 by means hereinafter described.

8 designates the usual operating lever or arm pivoted by a transverse pin 9 in the 1 aforesaid, and having at its forward end an operating, toe 10 adapted for operative engagement with the forward side of the adjusting screw sleeve 5 of the implement, so that in an active movement of the lever or arm 8 the sleeve 5 and associated adjustable member 2 will be forcibly moved heretofore described movement of the jaw 4 toward the jaw 6.

The plate metal housing 1 of the'present structure is formed from a blank or stamping of the shape shown in Fig. 4:, folded or bent to the rectangularv shell structure shown in end elevation in Fig. 3 with the seam or joint 11 formed by the'meeting edges, located centrally in the bottom web or wall of the structure, and with the top and bottom walls or webs preferably of an arched or segage the work or article lever or arm 8 has abutcompanion jaw 4 simultaneously with the adapted to provide receiving recesses 12 designates a' central rectangular aperture in the body of the stamping adapted in a folded condition of the same to provide the heretofore described receiving re' cess for the adjusting sleeve 5 aforesaid, and" one margin of said aperture 12 is formed with a pair of spaced recesses 12 adapted to form abutment recesses for the hereinafter described spring member by which the adjusting sleeve 5 is yieldingly held to its forward position. I

13 and 14 designate pairs of orifices adaptedto receive the pivot pins 7 and 9 hereto.- fore described, when the blank or stamping is bent or folded into shape.

15 designates a pair of rectangular corner extensions adapted to form the bottom wall or web of the housing shell l, when the stamping is bent or folded into shape. And with such construction said bottom wall is arranged at the rear end of the guide housingl to provide a limiting stop for the handle or lever 8 in its pivotal movement.

16 designates a pair of marginal notches for the ends of the hereinafter described transverse bridge piece or partition lG that affords an underbearing for the shanlrd of the adjustable member 2 in its sliding movement.

1 designates the bridge piece or partition above referred to, of a segmental or arch shape as shown and with its ends having a'drivefit in the notches or recesses 15 7 above described.

17 designates a plate metal spring member of the approximately rectangular form shown in Fig. 2 adapted to encircle the guide shank 3 of the adjustable member 2 and formed with forwardly disposed upper and lower portions 17 adapted to bear against the rear face of the adjusting sleeve 5 aforesaid, whilenear its mid-height said member 17 is formed withrearwardly curved bearing portions 17 adapted to bear and have abutmentin the recesses 12 in the rear wall of the aforesaid receiving recess guide housing 1 and hold .erating sleeve having ties midway the in which the said adjusting sleeve 5 is arranged, as illustrated in Figs. 1, 5 and 6, and so that said spring member will exert 2L" yieldingly stress against said adjusting sleeve 5 to hold the same against the forward wall of said receiving recess of the said sleeve 5 and associated parts from loose movement.

Having thus fully described my said in vention what I claim as new anddesire to secure by Letters Patent, is

1. In an adjustable tool of the type described, the combination of an intermediate guide housing formed with a transverse recess and provided with an operating handle, an adjustablej aw member. moving in said housing and provided with a revoluble opbearing in the aforesaid housing recess, a companion jaw member attached to said'housing the aforesaid recess of the housing having abutment caviheight of the same, and a spring member of arectangular frame form encircling the adjustable jaw, member and formed with upper and lower forwardly extendin portions bearing against the rear end 0 the aforesaid. operatin sleeve and with central rearwardly extendingabutment projections having bearing in aforesaid abutment cavities of the guide housing.

2. Aplate metal housing for adjustable tools comprising, an initially fiat metal plate or blank formed with a central rectangular aperture, the, lower edge of which is formed with two recesses which form abutment cavities for a springin the finished housing, with a pair of journal orifices, andswith a pair of rectangular extensions at two corners, said plate or blank being bent into a rectangular shell or housing with the various pairs of orifices and. recesses intransverse alinement and with the pair of corner extensions in transverse abut ting aSSOCIELUOH to constitute short coactlng CHARLES.
