Application flied Aprii 14,1924'. Y serial N10. 706,463.

The present invention relatesto `improvements in adjustable wrenches commonly known as monkey wrenches, and its particular object is to provide certain improvements l which render the wrench particularly easyV to operate and which furthermore provide a positive stop for the sliding inember'of the wrench requiringan actual release ofthe same before the sliding member can be ad- "id justed, instead of ielying on the mere frictional resistance of a threadedengagement providedA in a well known type of monkey wrench no'w on the market. 1

It is'furtlier proposed to provide in com bination with a wrench of this character means for securing thereto auxiliary tools such as ahainmer or a` second adjustable wrench of diierent capacity, orany other tools f of similar character.l Further objects and advantages of my device willV appear as the specification proceeds.

The preferred form of vmy invention is il lustrated in the accompanying drawing, in which Figure 1 lshows a plan view of the same; Figure 2 a side view; Figure 3 a detail view of a claw hammer adapted to be used' in connection with my adjustable wrench; Fi-gure an end view ,of the claw hammer; Figure 5 a detail view `of the back or striking portion ofa hammerada'pted to be used in combination with my adjustableVV wrench; Figure 6 an end view of the same,

Figure. 7 a detail view of an adjustable wrench of different roportions adapted'to l be inserted in my ac justable wrench; Figure 8 an end view of the wrench shown iny Figure 7; Figure 9 across section taken alongjline9---9 of Figure 1 and Figure 10 a perspective detail viewl ofy a toothed detentV used in my *wrench VWhile I have shown only the preferred formof my in'- vention, I wish to have it understood that various changes or modiications Vmay be made within the scope of the claims hereto attached without departing from Ythe spirit of'the invention.

'My wrench (1) includesl a stein (2) toothed throughout a' large portion of the same as shown at (3) and terminatingat its outer end in the head (4), which preferably projectsover opposite sides of the stem so as to be adapted to coact with registering projections of the sliding member (6) in engaging a nut, the head of a bolt or similarV objects. The sliding member (6) is formed to allow two detents (7 which are 1,599,202 PATENT oFieicis; f

sli'dably mounted therein land which are.v

toothed internally as shown at (8) to be pressed upon the 'toothed faces of the stem by means of leaf springs (9) secured on the outside of the sliding member (6)*- by means ofscrews (11):

The jtwo detents (7) are-in,y contact, Von

opposite sides of the sliding member (6),

with-slanting edges (12) of the platesV (1,3), j

which latter are slidable on the, side faces of the member (6) and areg'uided by `astud` (14) rising from each faceof the member 6) and extending intoya slot (16) in the member (13) The latter members are further heldV to the sides of the. member (6) by the fact that theslanting edges l( 12) ride in grooves lprovided in the detents (7). The )two members (13) serve as wedges. Flanges 13a are'provided 'at the lower ends o-f'the'wedge members 13 to facilitate the manipulation of these members.' vWhen 'j Y pushed downwardly they allow the two detents (7) to be `forced against the toothed faces of the stem (2) by thesprings (9'), and when pushed upwardly they force the two detents outwardly over the resistance Qof the springs .(9) so as to free the stern from the engagement with thedetents and Y vto allow the member (6)1to slide'onthe stem in" either direction.

. The :ooperatingv j aws 18jy and 19 .are pro-ill vided wth recessesito make possible the insertion of a tool *which would make the wrench useful for" diiferentpurposes. 'To

allow the front'portion or claw (17) of a hammer to be inserted'the two elements- (18) and (19) of thewrenchare recessed as-shown at (21) to receive registering projectionsl (22) on the claw of the hammer, tlieirecesses preferably comprising tapered grooves (22") terminating at their inner ends/Yin ,somey what deeper grooves (23), 'whileV the pro-v jections consist'lofl corresponding tapered ridges (24)"terminating in somewhat higher ridges (26).

The claw- (17 has a flat shank (27)l eX` tending therefrom adapted to be engaged by the flat faces of the elements (18) and (19) of the wrenchv and ending interiorly in a recess (28) adapted to fallow the shank to straddle the stem (2) of the wrench. The back or striking portion (31) of a hammer maybe secured between the two elements (18) and (19) in a similar manner. If it is desired to use a wrench vallovvin of a larger bite, the auxiliary device (32) l shown in Figure 7 may be used. The latter comprises a threaded'rod (33;) having a transverse head (34) secured to one end thereof, and a transverse base member (36) at the other end. A sliding member (37) providing the movable jaw of the auxiliary wrench may be advanced on the rod by'V ingmember of thev main wrench for' locking the ,auxiliaryy wrench in. place when the slide is tightened upon the same. The two jaws of the auxiliary device are preferablr formed with. corrugated inner faces as shown at (44).

The handle of, the wrench comprises a frame consisting` of. two parallel bars (47) connected at the: top. and bottomf by rings (48")L andl (49), the former being perforated as shownv at (5l) to allow. the stem (2.) to

passtherethrough, while the latter is perforated to receive. and hold against endwise motion the rod ('52) which latter is threaded so that it may berv screwed into and out of -the endof the stem (.2) for thepurpose of shortening andi lengthening the, wrenclr.` 1Wooden side pieces (53).l secured to the frame by means of a belt complete the The-:rod (5,2.)` may be turned by means ofthe knobv (5'5). The manner of usingmy wrench isv as follows: y

To adjust the wrench to receive a certain* nut or belt' head, the twoV plates or wedges (13) are pushedv upward so as yto force apart the two detents (7') 'anchoring ther sliding member tothe stem (2'). The member (G)v may now be slid back and. forth onf the stem until the proper adjustment has been obtained, whereupon the operator pushes the Y twofwedges dbwnwardly and allows the detents (7) to close inon the stem (2) and to hold the sliding member against endwise motion'. To insert the hammer, either the turning the rodA (52!) until the eXtreme length of the wrench hasbeen reached. The sliding member is then slid `downwardly on the stem (2') until the distance between it and the head (4) is suiiiciently large to.- al-- low the auxiliary wrench to be introduced between the same. The slidingimember is then forced upon the auxiliary wrench and the detents are allowed to close in on the stem by pushing the wedges downwardly.

I claim: 1.111 an adjustable wrench, a shanky of rectangular crossV section toothed enY oppositesides and terminating ina transverse T-shaped head, a' member slidable thereon f formed symmetrically on opposite sides of its center line, symmetricalv spring-Dressed detents associated with the latter normal-ly eno-aging the shank from opposite sides for holding thev member against endwise motion and two symmetricalv wedge members slidL able'` in the two det-ents' and disposed on the other twoA sidesA of the shank allowing. the

detents Vto be separated for releasing the sliding member,

2. lnx. an adjustable wrench, a shank? of y r :.ctangularV cross section toothed on opposite:

sides andl terminating` in.` a transverse 'F- shaped head, a member slidableA thereon V,formed symmetrically on opposite sid'es of its center' line,I symmetrical spring-pressed detents associated with the latter normally engaging the shank from opposite sidesv for hold-ing the' memberl against endwise motion and twol symmetrical wedge members slidf able in the two detents and disposed: ony the: other two sides of the shank allowing the detents to be separated forY releasing? the sliding member,A the wedge members" lia/ving flanges thereon facilitating the manipula*i tionof the same.
