Application sied November 10,1908. f 'serial No. 461,917.

Be it known that I, HARRY E. STEPHENS,

. citizen of the United States, residing at Elgin, in' the count-y of Kane and State of Illinois, have invented certain new and useful Improvements in Wrenches, of which t-lie following is av specification, reference bein-g had therein to t-he accompanying drawing.

rIhis invention relates to `Wrenches, and has: iii View certain improvements in the same whereby the nut engaging head thereof'may be set at various angles relatively to the'handle, so as to adapt the tool for operations in corners and the like, and also means whereby the said head may be readily removed from the handle when necessary or desirable.

In carrying out t-he object `of the invention set forth above it is contemplated einployiiig a ratchet on the underside Vof a pivoted segmental head with which cooperates a spring-pressed dog for holding said head in various positions relatively to said head, said dog being so mounted in and guided by a pair of spaced apart arms provided with a handle that'it will immediately slide to an engaging position with said ratchet when manual restraint of the saine isiremoved.V

It will be understood of course, that the essential features of the invention are'susceptibl'e of structural changes andvariations, vbut a practicaland preferred'embodiment of the same is shown in the accompanying drawings, wherein- Figure 1 is a front elevation of the improved wrench. Fig. 2 is a longitudinal sectional view of the same partially taken on the line 2--2, Fig.` 3.l Fig. 3 -is a similar view partially taken on tlievliiie 3-2-3, Fig. 1. Fig. 4; is a. fragnientaiy view similar to F ig. P3. Fig. .5 is an enlarged fragmentary view of thc pivot pin.

Like characters of reference designate corresponding parts.

Referring to the accompanying drawings,V

it will beobserved that the handle of the improved `wrench has one end portion iiatteiied and provided with parallel rounded sides as indicated atl which permits of the same fitting snugly in the hands of the operator, andfiom the upper end of said iatteiied portion 1, the handle decreases in width, but increases in thickness, as indicated at 2, and from suoli last mentioned portion, thehandle terminates. in the out-- stand ing sides between which the body of the metal is Abored out to form a longitudinally extending recess, or pocket, L1, forining a seatfor a coiled spring 5, The sides of the outstanding portions 8 3, preferably just below the upper end'of the longitudi-` nally extending pocket, 4, have an external recess 6 formed in them, and the bottoniI of each of vsaid recesses 6 has a guiding notch or slot 7 out through it, said notches extending into the said pocket and forming guides for outstanding lugs 8 of a dog 9 which is mounted in said pocket 4 upon the spring The outer end of the shouldered portion 3 terminates in spaced apart arms 10 and 10?* provided with registering pivot openings 11 `which receive the ends of a pivot pin 12 of a nut-engaging head 13. The said head 13 extends well down between the said arms 10' and 1()a so that it will just clear theyen'ds thereof, and on its lower, semi-cylindrical surface, is provided with a ratchet segment 14 with which the teeth 15 of the springpressed dog 9'engage, as is shown in Figs. 2, 3 and Il of t-he accompanying drawings. The' outer. end of said head 13 has been shown as provided witha nut-engaging recess 17, but it will Aof course be understood that, if preferred, it may be provided with the usual recess for manipulating pipe sections, should the tool be used for such purose. p Itfwill be understood from the foregoing description that the head 13 is normally held in a fixed relative position to the handle by means of the engagement between its ratchet and the spring-pressed dog 9, and that the ratclictteeth of the head and the dogare so Yshaped that pressure exerted on the handle in one direction will. permit of a relative movement of saidhandle to said head in one direction, but movement in the other direction will be prevented, unless the dog is pushed down into the pocket si againstnew position to compensate for any movement of the head when turning a nut.

In applying the head 13 to a nut or pipe section that is to be turned, the dog il is pushed down iii t0 its pocket 4 bv pressure exerted upon the lugs 8, which oisengages the same from the ratchet teeth 14 ofthe head, whereupon the said head may be rocked upon its pivot to the desired angle to permit its nut-engaging recess to be placed over'the nut.' When the head is in the desired position, the manual pressure upo'n the dog is removed, whereupon the pressure of the spring 5 Will cause the same to slide into engagement with the teeth of the head, and thereby lock the head and handle together.

In order that the nut-engaging head 13 may be removed from between the arms l0 and 10, one of said arms (10a) has a hinge Connection 19 with one of the outstanding sides 3 of the handle so that said arm may be swung outwardly therefrom to disengage its' pivot opening 11 from the pivot pin 12.

. a screw driver, prying tool, or the like.

It will be seen trom the foregoing that byy means of the hinged arni 10, the head 13 may be removed from between the arins 10a and 10, thereby permitting a different type of head to be substituted when necess ary or desirable, and also greatly facilitating the cleaning of'the saine.

l/Vhat I claim as my invention is 1. A AWrench comprising a. handle provided with a longitudinal pocket. in one end, y

arms projecting from opposite sides ot said pocket., one of said arms being integral with 1 said handle, the other arin having a hingeI connection with said handle and being provided with an opening, a pivot pin earried by the integral arin and having a spring mounted on one end over which said hinged arni snaps when inaclosed position, n. spring seated in .said pocket, a dog mounted on said spring and adapted to be guided longitudinally by said arms, and a head pivotally mounted between said arins and adapted to be engaged by said dog.

2. i wrench comprising a handleprovided with a longitudinal pocket in one end, arms projecting from opposite sides 4of said pocket, one of said arms being integral with said handle, the other arm being hinged to said handle, a pivot pin carried by the integral arm and having a recess in one end, a shouldered spring seated in said recess and over which said hinged arm snaps when in a closed position, a spring seated in said pocket, a dog mounted on said spring and adapted to be guided longitudinally by said arms, and a head pivotally mounted between said arms and adaptedto be engaged by said dog.

3. A wrench comprising a handle provided with. a longitudinal pocket in one end, arms projecting from opposite sides of said pocket, one of said arms being integral with said handle and the other hinged thereto and provided with a latehing opening. a pivot pin carried by the integral arin, and with which said hinged arin engages,.a nutengaging head carried by said pivot pin,

head in various positions relative to said handle. i

4. A wrench comprising a handle provided with a pocket in one end, arins projecting from opposite sides of said pocket. one otl said arins being hinged thereto and provided with a latehing opening, a pivot a latch which engages with the opening in the hinged arm, a nut-engaging head carried by said pivot pin, and a spring-pressed dog seated in said pocket and guided longitudinallyv by said arms to engage with said head.
