tion.. i y This inventlon relates to. compound tools A and has for. its objectlthe provision of a SiIIlpLel i001 Iby the .use ofavhich a variety of.

operations may be eiileiently performed.

One object ofthe invention 1s to provide -a.,wrench which willautomatically. adjust.

itself-tothe nut-or bolt to be turned and will notF mar. thel finish of thel saine nor wear away l the sharp? angles or corners thereof.-

A further'objectof thevinvention is to provideI a wrench4 which maybe easily operated Within a' restricted space. Without causingianyV undue. fatigue on the partof the, operator.

The inyentionalso.. has for its objectthe provision oya tool which may; be produced at a slight"cost and twill proveeiicient and durablein use.

All thesestated objeotsand such; other in.

When the screw driver. or other. tool is withdrawn into the handle, the sleeve 12 engages the. upper recess 5.', andi thereby serves. as a4 locking. .pin to, hold the/top l'refv traeteda- Shouldjtx be desiredio A11.se.-the

aregrasped and kmoved laterally againstthe tension lof the spring 13 so as vto, release the angular sleeve or lockinglpin from the ref cesses 5 after which the toolfis movedv lori.-`

gitudinally until the cross head anddock-V K ing pin reachthe outer: ends ofthe slots 4 whereupon. the spring lwill at :once projectthe angular sleeve or locking pin. into enf gagement with the lower recessesl 5g and thereby hold the tool projected. The toolinay then be `usedin the ordinary' manner without any liability of it collapsing or withdrawing from. the; work.

Thel end ofi-the K shank .1; distant, from the llo hollow handle`2 is formed into a gear or circular rack'15 and fits between a pair of cheek plates 16 which'v form a housing pivJ oted vto,the said rack or gear at the center thereof. The upper portions of the cheek plates are formed integral with or secured ri'gidly to a sleeve 17 which extends long1- tudinally or in the same plane as the circular rack or gear 15, and between the said sleeve 17 and the circular rack or gear the inner faces of the cheek plates" are formed with longitudinal grooves or guides 18 as shown." A base or rack bar 19 is slidably mounted in the grooves 18and has teeth 20 formed on its outer or lower edge to mesh with the gear whereby when the handle is swung'to one side relative movement of the rack barand the gear .will be e'ected.

f One end of the base bar is formed integral with or has rigidly secured thereto a foot or boss 21' having a cavity `in its inner face as shown at 22. 'At the opposite end of the said rack bar is provided a short standard or arm 23 having a hollow 'boss 24 at its free end, the said boss 24 and the cavity 22 consti/tuting bearings for a shank or zstem 25 having a jaw 26 formed integral therewith. A spring 27 is housed within the hollow boss 24 so as to bear upon the end of the said stem or shank` 25 and hold the same properly seated within the cavity 22 and thereby compensate for wear ofthe parts so that the jaw and its stern will not become loose through long rcontinued usage. The stem or shank 25 passes through the sleeve 17 and is slightly reduced at diametrically opposite points to provide the flat faces 28 as clearly shown in Figs. 1 and 2, the said flat faces slidably engaging corresponding faces in the lugsor bearings 29 of the jaw 30 which lugs orbearings engage the opposite ends of the sleeve 17 as clearly shown.

It will be readily Iseen that the stem 25 may be 4turned to any desired' angle in its bearings and in Fig. 5 I have shown the said stem with the jaws thereof turned to an angle of 90 degrees to the handle. The

wrench can consequently be used in narrow or restricted spaces without undue-strain on any ofthe parts and without discmfort .to the workman. A,

When it is desired to use the wrench the handle is turned to the position shown in Fig. 1 with the jaw 26 against the nut or head of the bolt to bexturned. If the handle be now turned toward' the jaw 26 the gear 15 will be caused to travel upon the rack bar 20 and the cheek' plates 16 will conse- 'quently be caused to move with the'handle toward the said jaw.- The sleeve 17, being rigid with the lcheek plates and fitted between the lugs or bearings 29 of the jaw 30, will impart'movement directly to the s'aid jaw so that it will be moved toward the jaw 26 and positively engage the nut so that the continued movement of the handle will turn the nut. If the handle be moved in the reverse-direction, the jaws will vbe moved apart and the Wrench consequently disengaged from the nut so that a fresh grip may be obtained thereon without any marring of its surface or any Wearing away of its corners. The wrenchis consequently especially well adapted for use upon softl 'metal or upon highly finished nickel plated :goods or other delicate parts.

It will be noted that in order to apply the wrench to turn up-a nut, it is only necessary to engage the rigid jaw against the side of thenut and then move the handle in the di` rection in which the nut is to be turned. No previous adjustment of the movable jaw is required and none is needed during the operation of the tool. j.

The teeth on the rack bar may be of any desired number or size according to the size of the wrench, and at the end of the rack bar `I provide a beveled spur or tooth 31 which \is adapted to coperate with notches 32 formed in the edges of the cheek plates 16 to cut a wire, as will be readily understood.

` The tool may also be used upon pipes, and

to this end I form an'opening 33 through one or both of the jaws 26 and 30 to receive a suitable retaining pin whichalso passes through perforated ears 34 on the side plates 35 of a serra-ted javir or block 36 which may bev fitted against either of the jaws 26 and 30 and held thereon by the said retaining pin. In order to`more securely maintain the said auxiliary or serrated jaw in place the side-walls 35 "thereof are provided with extensions or tongues 37 having curved ends adapted to it around the stem 25 and the lower edge of the said auxiliary jaw is fur- `-ther provided with a recess or-curved notch 38 adapted to fit against the said stem 25.

Having thus described my invention what is claimed Vas new is:

' 1. The combination of a rack bar, a housing slidably Iittedtheren, a jaw supported by the rack bar and held against movement longitudinally of the same, a jaw engaged by the housing, and a handle pivotally mounted within the housing and engaging the rack bar whereby movement of the handle will effect movement of the jaws relative to each other..

2. The combination ofa base bar,-a jaw having a stem swiveled -upon the said bar, a second jaw slidably mounted upon. said stem, and means engaging the base bar and the said jaw to effect relative movement of the jaws.v

3. The combination of a base bar havin an upturned end, an arm at the opposite en of said bar, a wrench jaw'having a stem swiveled in the said upturned end and in `the said arm, a spring housed within Vthe said 'arm and resting 'against the end of the stem, a jaw slidably mounted on the said stem, and means 'for moving said slidabe jaw to and from the first-mentioned jaw.

4. The combination of a rack bar, a pair 0f wrench jaws mounted thereon, a housing slidably fitted on the rack bar and engagin one of the jaws, a handle pivotally mounte within the housing and having its end formed into a gear engaging the rack bar, and a beveled tooth on the rack bar, the housing being provided in one edge witl` notches adapted to coperate with said beveled tooth.

5. A tool comprisin a handle, a jaw support, jaws swiveled t ereon, a handle arranged to oscillate in the longitudinal plane of the jaw support, and means whereby movement of the handle will cause one of the the end of the handle an jaws to approach or recede from'the other jaw. v n

6. A tool comprising a handle, a jaw support, a jaw having a stem disposed longitudinally of the support and swiveled thereon, a housing inclosin the support and having a sleeve fitting around the said stem, and a jaw having lugs engaging the ends of said sleeve and having a slidable engagement with the said stem but held against rotation upon the said stem.

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