The wrench" disclosed inFigs. 1 to etcomprisesY ahandlerlconsisting'l of a tubular handle portioii llfand afi'otativei'handle portion 122 A xedjaw member lfisrmounted'onvoneend of the tubular handlefportion Il.A The fixed-jaw member/l 3-is svveatedonto theV tubular handleportion Il oritfmay -bewelded,f.brazed or in any other manner securelyfattaehed in positic n.

rIfhe 1 rotative handle portion I2- is. disposed Within the tubularl handle portionY H,- and Ais formed at the end of the tubularhandledportion ll'ad'jacent the-iixedljaw'member I3; Withan enlarged head@ I4` which prevents theV rotative handle?. portionv l 2 ffromf beingeW-ithdrawnfrom Fig. 12 is a perspective view of the other jaw 55 the tubular handle portion Il. The opposite end of the rotative handle portion I2 is formed with a knurled extension I5 by which the rotative handle portion II may be conveniently rotated. As shown the knurled extension projects beyond the end of the tubular handle portion II in abutting end relationship, and in assembling the handle portions II and I2, the handle portion I2 is inserted into the tubular handle portion II from the end opposite they xed jaw member I3 and the head I4 is Iformed on the inserted end of the rotative handle portion I2.

An intermediate area of the rotative handle portion I2 is knurled, as indicated at I6, and the knurled area is in alignment with diametrically opposite openings I'I formed in the sides of the tubular handle portion II. In using the wrench,

4 portion II, and is formed with diametrically opposite inwardly extended lugs 20 extended into the interior of the tubular handle portion II through diametrically opposite slots I9' formed in the handle portion Il. The inner ends of the lugs 20 are formed with the threads I8Bm engageable and disengageable with the threaded end I2a of the rotative handle portion I2. The lugs 20 are securely welded in position within complementary recesses 2| formed in diametrically opposite sides of the movable jaw I8.

In other respects this form of the invention is similar to that previously described, and like fingers can be inserted through the openings I1,

to contact the knurling I6 to facilitate rotation of the rotative handle portion I2 from that area of the tubular handle portion I I.

A movable jaw member I8 has one end inserted into the tubular handle portion I I through a longitudinal slot I9 formed in one side of the tubular handle portion. The inserted end of the movable jaw member I8 is formed with an opening engaged about a reduced threaded end I2L formed on the rotative handle portion" I2. The reduced threaded end is formed with flat sides I2b (see Figs. 3 and 4). At diametrically opposite sides the movable jaw member I8 is formed with inwardly directed threaded areas I8, which are selectively engaged with the threads of the threaded end I2EL of the rotative handle portion I2 or disengageable from those threads as shown in Fig. 3.

The fiat sides I2b on the rotative handle portion I2 interrupt the continuous nature of the thread on the threaded end I2fl of the handle portion I2, and when the threads are disengaged as shown in Fig. 3, the movable jaw member I8 is free to be easily moved longitudinally of the handle I relative to the fixed jaw member I3. A 90 degree turn of the rotative handle portion I2 from the position shown in Fig. 3 will engage the threads on the movable jaw and the threaded end I2El of the handle locking the movable jaw I8 in a desired fixed position.

The method of using the wrench shown in Figs. l to 4 is as follows:

With the threads I88L on the movable jaw member I8 disengaged from the threads on the threaded end I2a of the rotative handle I2, the fixed jaw member I3 is engaged against one side of the object it is desired to tighten or unloosen', and the movable jaw I8 is slid along the length of the slot I9 to a position engaging the opposite side of the object. The rotative handle portion I2 is given a quarter turn to engage the threads I8a of the movable jaw with the threads on the threaded end I2a of' the handle portion I2 to lock the movable jaw member I8 in position. The wrench is then used in the customary fashion to tighten or loosen the object upon which it has been engaged.

To remove the Wrench from the object, the above procedure is reversed. It will be understood that the present invention provides a wrench which can be quickly adjusted to receive objects; such as, nuts, bolts, pipes, and the like, with a minimum of time and a minimum of turning action.

In Figs. and 6, a modification of the wrench is disclosed, in which the movable jaw I8 is engaged about the outside of the tubular handle -handle portion 32.

vreferencenumerals identify like parts in all the views.

4In Figs. '7 and 8 another modification of the invention is shown in which a handle 30 consistsfof a fixed handle portion 3| and a rotative The rotative handle portion 32 is tubular and the fixed handle portion 3| is extended through the tubular Vhandle portion 32. One end of the fixed handle portion 3l extends from the adjacent end of the movable 'handle portion 32 as a 'knurled grip 33, and the other end of the fixed handle portion 3| extends from its adjacent end of the movable handle portion 32 and has mounted thereon a xed jaw member 34.

A pin 35 extends through the movable handle portion 32 and extends into a groove 3B formed in the xed handle portion 3| for rotatively retaining the movable handle portion in a fixed rotative position adjacent the knurled grip 33 of the iixed handle portion 3I.

A ,movable jaw member 31 is slidably disposed on the fixed handle portion 3| and is formed with a socket opening 38 into which the adjacent end of the movable handle portion 32 extends. Diametrically opposite sides of the inserted end of the movable handle portion 32 are formed with spaced threads 32B between flat sides 32D. The threads 32n are selectively engageable with and disengageable from complementary threads 31e formed on the movable jaw member 31 within the socket opening 38.'

With the complementary threads 328L and 31 engaged as shown on .the drawings, the movable jawv'31 will be locked in a fixed position relative to the fixed jaw 34. However, if the movable handle portion 32 is given a quarter turn, the threads 32sk and 31B Will be disengaged and the movable jaw portion 31 will be free to be slid to any desired position relative to the fixed jaw member 34.

In the modification of the invention shown in I Figs. 9 to l2, the wrench comprises a handle 40 havingits end 40 knurled, to better adapt .it for gripping.l The opposite end 4IIb of the handle is reduced and passed through an opening 4I formed1in a fixed jaw member 42. The end 4I)b is milled over after being inserted into the opening' 4I to retain the fixed jaw in position on the endfof; the handle, but it is pointed out that thehandle 40 is free to be rotated relative -to the fixed jaw member 42. Y

A movable jaw member 43 has ya portion 43" received within a socket opening'42a formed in the fixed jaw 42. The portion 43l continues into an intermediate portion 43b extended through a passage 42b formedin the side of the fixed jaw member 42 opposite its jaw element 42. The lntermediate portion 43b of the movable jaw member 43 in turn continues into a jaw element 43 which is adapted to cooperate with the jaw element :i2c of the xed: jaw; member 42 in. clamping. an object tobe tightened or loosened.

The handle 4U passesA through. an opening formed in the portion 43e. of.V the movable jaw member 43 and that areaV of4 the handle III)v is formed with spaced threads 4|1fbetween flat sides 60d. The opening in the portion Marot the movable jaw member 43. is :formed with spaced threads i3d selectively engageable with and disengageable from the threads 40c of the handle 56. When the threads are engaged the movable jaw member d3 is locked inA position, but when the threads are` disengaged, as shown in Figs. 9 and 10, the movablevjaw member-'4:3 isfreeto be moved longitudinally,- relative to the.` fixed jaw member 42.

In Figs. 13 to 16 of they drawings, another'modication of the invention is` disclosed inv whichv a fixed jaw member 50 is formed integrally with a tubular shank 5|. A movable jaw'member 52` is formed on the end of astem 53 which, extends through the iixed jaw 50 andthe tubular shank 5|. A pin 54 is extended through. one side of the tubular shank 5| and extends into a longitudinal groove 55 milled in the side of the stem 53 to limit the stem 53 to longitudinal sliding movement only relative tothe tubular shank 5|.

A rotative handle portion 56 forms an extenion of the tubular shank 5| and; engages over the end of the stem 53 which` projects from the end of the tubular shank 5|. A collar 51 is threadedly engaged upon the end of the tubular shank 5| and has an inwardly directed flange 51a which engages an outwardly directed flange 56il for rotativelyv connecting the handle portion 56 to the shank 5|.

Within the rotative handle portion 56, the stem 53 is formed with threads 538L separated by diametrically opposite flat sidesV 53,b formed on the Ystem 53. The interiorof the rotative handle 56 is formed with diametrically opposite threads 56b which are selectively engageable and disengageable with the threads 5 3* formed on the stem 53. With the threads 53e and 56b engaged as shown in Figs. 14 and 16, the stem 53 and in turn the movable jaw member 52V will bej lockedin position relative to the fixed jaw member 50. In a ninety degree turnedposition of the rotative handle portion 56, the threads. 53B and 56b will be disengaged freeing thestem53 vto, be slid-longitudinally in the shank 5| to-adjust; the position of the movable jaw member 52 relativel to the fixed jaw member 50..-

In the modication of the invention disclosed in Figs. 17 and 18, the iixed jaw 60 is mounted on one end of a handle 6| formed at its other end with an enlarged gripping portion 62. A movable jaw 63 is slidable onthe handle 6| between the fixed jaw 60 and the enlarged gripping portion 62. A bushing 6'4- lsrotatively disposed in an opening 66 formed in the movable jaw 63 and is rotatively retained in position by. apin 65 extended in from one end of the movable jaw member 63.

The bushing 64 is located along. one sideof the handle 6| and is `formed with threads 64EL and a flat side 64b. The threads 64%.of the bushing 64 are selectively engageable with and disengageable from complementary threads 6| a formed along the adjacent side of the handle 6|. t

When the threads 6|f-and64 are engagedas shown on the drawings, the-movable jaw-'member 63 will be locked against movement relative to the xed jaw member 60. However, when the bushing 64 is rotated to align its flat side lillb with the threads 6|* ori theA handle 6|, the movable jaw member 63 will be free to move on the handle 6| to desired adjusted position relative to the fixed jawV 60.' y

If desired, the end` of the pin 651maly be provided with a suitable handle or knob by= which the pin may be rotated for' turning the bushing 54 for engaging and disenga'ging its threads 649' with the threads 6 leon 'the side ot the handle 6|. If the pin` 65 is provided with such a handle or knob, it is appreciated that the` bushin'gl will have to be securely attached 'tonthe-lpin- 65a v'The modication of the'v inventionl shown in Figs. 19` to 21 is somewhat similarto-that shown'V in Figs. 17 and 18. In thisforrn of the invne tion ank expansior'rr spring 1|!` mounted.v on 'the handle 6I' and: operates-*between thee'nd of the movable jaw member 63' and the gripping portion 62' oi" thehandle 6|l fornormally urgingthe movable jaw member 63l toward the fixed jaw member 66, in the freed'po'sitionof the movable jaw member.

Also, in this form of the invention there is a riodied construction for lock-ing the movable jaw 63 in positiony relative to the iixed jaw 66.

In this form of the invention, the handle 6|r is formed with a projecting ledge 1| formed with serrations lla, and the adjacent wall of the'movable jaw member 63 is formed with a cutout 12 which houses a slide13 for-movement toward and away from the serrations 1|a1offthe ledge 1|.

Means is provided for moving the slide 1'3 to engage serrations 13e, formed thereon,`with and disengage them fromthe serrati'ons 1|a. This means comprises astud shaft 14- extendedthrough the movable jaw member 63 andy formed at its outer end witha small hand1e`15 by which the stud shaft 'Mean-be rotated. A` disc 1 6 is eccentrically mountedonY theinner end of the 'stud shaft M and is disposedA in a cam opening 11 formed in the slide 13. In. one rotative position of the disc 16,*the slide willbeinA theY position shown on the drawings, see Fig. 21, vin which the serrations 73a on thev slide 13 will be engaged with the serrations 'He on the ledge TI, of the handle 6| for locking the movable jaw member 63" in position relative tothe fixed jaw. member 60. In a 186 degree turned position of the disc 16., the slide E3 will beA moved from the positionshown in the drawings, to a position in which the serrations 13a and 1| a will be disengaged freeingthe movable jaw member 63' to bemovedrelative to the iixed jaw member 6|).

Vl'n the disengagedpositionof the serrationsHa and 13e, the spring1|1 will act tourge the jaw members Stand-63 into facial contactgorto urgeA the movable jaw member 63 into contact with anobject inserted between the jaw members.

In Figs. 22 to 25, the modiedgwrench com-. prises a fixed handle 89 havinga fixed jaw mem-y ber 8| attached to one end andprovided at the other end with a knurled grip-812. Amovable-jaw member 83 is slida'bleV on thehandle 8,0, and the portion of the handle 8U engaged by the movable jaw member 33 is ofA coniiguration;e.v g'.- square oi'V hexagonal, to hold thegmovable,jawxmember 83" against rotation on the-handle.

A rotative handle 84 is rotatively attachedto the rear end of the movablejaw member 83, and the rotative connection is accomplishedby acollarY 35` which isy threadedlyiengaged intdtheend ofj the;movable;v janv.,memberl 83; Th'ee-cellarvv 85 has an inwardly directed flange 85a cooperating with the outwardly directed ange 81|EL on the rotative handle 84 to rotatively retain the handle 84 inposition.

Internally, the rotative handle 84 is formed with spaced threads 84". The immediate area of the handle 80 is formed with diametrically opposite fiat sides 80EL separating threads 80". The threads 80b of the handle 80 when separated from the threads 84b'on the rotative handle 84, leave the handle 84 free to be moved longitudinally to similarly move the movable jaw member 83 relative tothe fixed jaw member 8|. Engagement of the threads 80b and 84h, in their rotative positions of the rotative handle 84, locks the movable jaw member 83 in a fixed position relative to the fixed jaw member 8 l.

In Figs. 26 to 28 a still further modification of the invention is disclosed comprising a fixed jaw member 90 in the form of a frame adapted to be engaged about a hexagonal bolt, nut or similar hexagonal member. A handle 9| is integrally formed with the fixed jaw member and extends laterally from one side thereof.

A movable jaw member 92 is disposed Within the frame forming the fixed jaw member 90, and novel means is provided for slidably supporting the movable jaw member.

The xed jaw member 90 is formed with an opening 93 in which is disposed a ring 94 which has its outer periphery knurled. The movable jaw member 92 is formed with a stem 96 which extends through the ring 94 and into a recess 91 formed in the handle 9|.

As shown in Fig. 28, the interior of the ring 94 is formed with spaced threads 94 cooperative with spaced threads 96a formed on the stem 95 to hold the stem 96 and the movable jaw member 92 against movement relative to the xed jaw member 90. .The threads 96a on the stem 96 are separated by flat sides 96b formed on the stem, and when the ring 94 is rotated through 90 degrees to disengage the threads 94 and 96n and to align the threads 94a of the ring 94 with the flat sides 96b on .the stem 96, the stem will be free permitting lits longitudinal movement to similarly move the movable jaw member 92.

In Fig. 29 a further modification of the invention is disclosed, which is similar to that shown in Figs. 26 to 28, differing merely in the formation of the movable jaw member 92'.

In this form of the invention, the movable jaw member 92 is formed with a V-shaped recess |00 arranged to cooperate with the fixed jaw 90 in gripping a square bolt head, nut or similar square object indicated by the dot and dash lines |I.

In other respects this form of the invention is similar to that disclosed in Figs. 26 to 28, and like reference numerals identify like parts in the several views.

In all forms of the invention illustrated, the sliding parts are all formed with cooperating pairs of flat surfaces; however, if desired they may be provided with single flat surfaces. Also, all cooperating threads may be single or plural threads, and preferably the ends of the threads at the sides of the fiat surfaces should be beveled for guiding the engagement of the threads when the parts are moved from positions in which the threads are disengaged to positions in which the threads are engaged.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right 8 is reserved to all lchanges and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:
