WRENCH.

Application filed February 12, 1914. vSerial No. 818,335.

To all whom 'it may concern:

Be it known that I, vWiLL'iAM T. LONG, citizen ofi the UnitedV States, residingy at Auburn, inthe county of KingV and State of-'Washingtom haveinvented certain new and useful Improvements in Wrenches, of which'the following is a specification.

Y This invention relates to wrenches and has for one object the rprovision of a simple, strong and durable'wrench in which the jaws may be made to approach or recede from eachother by an oscillatory movement of the handle and in which lthe receding, movement of the jaws may-)bet arrested at any desiredpoint. 1; Y f

A further object of the invention is to provide a wrench in which the aws may be disposed in angular relation to the jaw support and locked in such angular relation.

A furtherob'ject of the invention is 'to provide a wrench of such construction that the parts *will be protected against injury and may be easily manipulated to effect the desired' adjustment. n Y

The several stated objects and=such other incidental'pbjects' as will 'appear from the following description areattained in a device ofthe'character illirstrated in the'accompanying drawings, and the invention consists in `certain novel 4features which will be pointed outv in the claims following the detailed description. l.

Adjacent the pivot-pinfoi'bolt the handle is .provided with a Atransverse 'i0p'e`n-' ing in which is'hous'ed a coiled spring 5,' the' ends of .which are adapted torpress against the inner faces of the cheek-plates'land thereby compensate for wear ofthe parts' andk prevent the handle moving laterally` `after long continued use. The'cheekplatesare extended beyond the end of theI handle and elongated laterally with respect theretosoas to deceive a base-bar 6 having onefedge" formed with teeth 7. adapted to be engaged by the segmental gear 2. The'elongated por- :tion Vof theA cheekeplates constitiitesfa hous-V ing indicated at 8'toV fit around the'sai'dYbasebar and thereby guidethe-.same iin2 the frela# tive movement ofv the housingfandi thebase bar in the operation of'the `wrench.Ihef' .cheek-plates v'are connectedat' their outer; edges byf-a web 9i and arealso connectedat opposite sidesy of the handle withlsmalliwebs" 10 whereby a tubular. support?for-.,the base` lbar is provided. Uponlltlie web I9sfis" pro'- Ivided a sleeve or eye 11 whichisadapted tot `fit around the stemor shank1`2,f=as clearly shown. The said stem oi' shank-12t hasa aw.; y 13 rigid with one end an'e`i preferably formed integral therewith, the said Aend of the shank orstem being'notched as'iiidicatedffat 149 wherebyto provide an outer lug lthrough" which a fastening bolt or as'shown in Fig. 2.

It will be noted that the notchfflllfii-'eceivesg :95?` and: the fastening pin or'screw "16 "passesr' aY lug or ear 17' formed upon -theibasesb'ar through the said lug or ear into the-shank' Aorstem so as to forma .swivelfconnectionl i between the base-bar and the shank.r The,

inclined or beveled lug Vortoothfl' yis'formed at the junction/ of said face withfthe 'shank so lthatthe jaw'm'ay more'readily engagea `v hexagonalv nut. 4'It ywill also be noted/thatt the,v body ofy the 'jaw is elongated'or pro-v1;

vided with a curved web or-'lip 19 extending from the outer end of thejaw to the lug "or 1 eye 15 so ,thatl the .jaw-willgjhavea .substantial body and; jconteq'iiently, possess great 21 ilo face 21 constitutes the terminal of a shankengaging portion or sleeve 24 which l is formed with the said jaw and adapted to t around the shank or stem 12, as clearly shown.. The inner opposed faces of this sleeve or shank-engaging portion are flattened so as to engage the flattened sides 25 of the shank in order that while -the jaw may move longitudinally upon the shank it cannot rotate about the same. The inclined or beveled face 21 coacts with the Working face of the jaw so as toenable the jaw to readily engage a hexagonal nut in the same manner that the lug or projection 18 coacts with the working face of the jaw 13.

The jaw 22 is provided with a notch or recess- 26 which receives the eye or ring 11 extending from the` housing 8 so that the movement of the housing relative to the basefbar or jaw support will effect a corresponding movement of the jfaw 22 upon the shank or. stem 12 relative to thev jaw 13. T he jaw 22 is further provided With a' small recess or scat 27 adapted to receive the lug or projection 18 when the jaws are brought together' so that they may loemade to engage a very small nut or bolt head.

It will. be readily understood from the foregoing description, that when the handle 1 is oscillatcd upon its pivotal connection with the cheek-plates the gear A2 will tend to ride upon the rack teeth 7 and, consequentty, relative. movement of the handle and the baseball will be effected. The cheeloplates will, of course, follow thel movement of the handle and, consequently, the jaw 22 will bel causedto move toward or4 from the jaw 13, inasmuch as the guide or feyc* 11. extending ro'nr the housing 8 which forms an elongation oli the cheekplates fits 4within the notch in the jaw 22 and torces the said jiaw to follow the: movement of said housing and cheek-plates TheI bore of the guide or eye 11 is circular so that the stem or shank 12 may rotate easily therein under proper manipulation of the wrench. The errd of the shank 1:2 remote' from the jraw 13 is provided with aiannular groove 28 through which may pass a pin 29 inserted transversely through the standard or housing 30 which secured to the adjacent end of the base or rack-bar 6;. as clearly shown. This. pin. 29 by engagthe groove 28 forms a swiveled conncction for the adjacent. end of the shank so that both ends of the said shank will! be supported upon the base-bar in. such a manner that the shank may rotate about its own longitudinal axis but cannot move axially along the base-bar or support. The shank may be thus turned into angular relation with the base-bar or support ,so that the jaws may be caused to enga-ge a nut in a restricted space or in a corner and the wrench manipulated Without discomfort or excessive fatigue to the workman. The extremity of the shank beyond the groove 28 is provided with radial slots or notches `31 which are adapted to be engaged by a latch 32 so as to lock the shank in any position in which it may be set. This latch 32 is pivoted Within the housing or standard 30 and is provided on its opposite sides with milled thumb-pieces or handle members 33 adapted to extend through and seat in notches 34 formed in the outer edges of the standard or housing 30, as clearly shown. A spring 35 is seated in the end of the base-bar or support and extends between the sides of the standard 30 to bear upon the end of the latch 32 so that the latch will be held normally toward the shank. 'vided with a tooth 36 which lies adjacent The latch is prothe spring 35 and thereby prevents the .spring slipping from the housing or standard and holds the spring in operative engagement with the latch at all times.

As shown in Fig.v 5 the standard or hous- .ing 30 is constructed with an open-ended Islot 37 to receive the Working end of the latch 32 and prevent lateral movement thereof so that the latch will always be in proper position to engage one of the notches 31.v The standard is also provided With a circular opening 38 to receive the enrd of the shank 12 and further provided with an ari-- guiar opening or socket 39 to receive thev end of the base-har or' jaw supportv When the latch is in engagement with the stem or shank the finger-pieces 33 will lie flush within the notches or seats 34 so that they will present no projections or obstacles which might interfere with the successful operation of the tool. When it is desired to m-ove the jaws into an angular position relative to the base-bar or j:awsupport the latch 32 is released from' the end of the shank and the said shank is then rotated about its connections with the support until it reaches the desired angle, after which, the latch is permitted to spring into engagement with the notches or slots 31 in the end of the shanlc 1t will, of course, be readily understood that the jaws` may be moved tov either side of the support or may be ar".

ranged in the longitudinal piane of the han-'- dle and will be held in either of said positions: by the engagement of the latch 32 with the notches in the end of the shank.

1n the ordinary use of they wrench theA handlethcn swung towardzfsaidjaw. This action causes lthe 22 to'move toward the jawzlfand, consequently, effects a. binding engagement of the same upon the nut so that the continued movement the handle will turn the nut. Upon-movement ofthe-handle' from the nut thethumb-latch,fiOprbifided:

in my present tool will be fou-nd highly effi,- cient. Ordinarily, oscillation of the handle to effect such reverse movement of the nut would simply move the jaw 22 away from the jaw 13, but by providing the thumblatch 40 I am enabled to hold the jaw 22 at any point along the shank and the base-bar. It will be noticed that this thumb-latch 40 is provided with a shank piece or handle member 41 which lies adjacent one edge of the handle and from which extends spaced plates or jaws 42 which t over the handle and upon the opposite sides of the same. A pivot pin 43-is inserted through these aws 42 and the handle, and the aws are provided with gripping faces 44 adapted to engage the adjacent edges 45 of the cheek-plates so that the movement of the cheek-plates will be arrested. Small teeth, indicated at 46, may be provided upon these engaging faces 44 and the edges 45 of the cheek-plates, but these teeth are not absolutely necessary, although the provision of the same permits a more positive holding of the cheek-plates. The latch is normally held out of engagement with the cheek-plates by a spring 47 secured to the under side of the thumb-piece or handle member 41 and bearing upon the handle 1 of the tool.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that I have provided an ex ceedingly simple and eiiicient tool which may be readily manipulated in restricted places and without any discomfort to the operator.

In order that the range of usefulness of the tool may be given the greatest possible scope I provide a supplemental jaw 48 which may be fitted to one of the jaws 13 or 22 and thereby convert the tool into a pipe wrench. This supplemental jaw 48 is provided with a serrated working face 49, as clearly shown, and has spaced wings 50 adapted to fit against the opposite sides of the jaw 13 or the jaw 22 and be secured thereto by a pin inserted through openings provided for that purpose. The supplemental j aw is constructed with a notch 51 to permit it to fit close to the shank 12 and also is provided with a tooth or lug 52 on its rear side adapted to en age the recess 27 in the jaw 22 so as to be rmly seated against the jaw and held'f-against lateral movement Having thus describedl the invention what is claimed as new is -1. A tool comprising ahandle, aj aw support, jaws:- swiveled thereon, the.:handle being arranged to oscillate in the. longitudinal plane ofrthejaw-support, means whereby movementof the'. handlewillfcairse one. of the jawsmto approach or recede from the other jaw, and lmeans to hold-said jaw atf YlliOuS- points of its receding travel.
