F. c. HAYCHENEY WRENCH Filed July 16$ Patented July 8, 1924.

PATENT mm FRANK o. iicnnnnv, or JOHN DAY, OREGON.

"1" WRENCH;

. i' jApplication filed I1i1y '16, 1923-. SerialNo' 651,925

To all whom itmag concern: I

I Be it known that I, FRANK CL. HA nE -EY, a citizen .of the United states residin'g at John Day, Grant County,'in the State of Oregon, have invented certain new and useful Improvements in Wrenches, of which the following is a specification. V

" This invention relates to wrenches. and

more particularly to an adjustable wrenchhaving a jaw which is slidable andja jaw which is pivoted, together with means for conveniently positioning the slidable jaw with respect to the pivoted jaw and for holding the jaws securely and rigidly in'adjuste d position. The wrench comprisingi fthis invention may also belprovided with. ahead constituting a semi-socket so thatv a bolt head, nutporthe like may be gripped on four sides, and at the same time the aws constitutingthe head of thewrench are also designedso that ;the wrench may be used on round objects, such as bolts and the like,

'The main object ofthe invention is to provide a wrench having the above mentioned characteristicsand other objects of the invention will be apparent fromthe folloW- ing description and the'accompanying drawings forminga part of this specification; ,In the drawings;

f Fig. 1 is aside elevational view of'the wrench;

Fig. 2 is a longitudinal sectional view of thewrencli; V

Fig. 3 is a sectional view on the line 33 of Fig. 2;: I r

. Fig; 4 is a sectional view on line 4-4 of Fig. 2;

1 Fig. 5 is a sectional view on the line 5-5 reference character designates the handle which maybe knurled as shown and provided .with the finger grooves 11. Continuous with the handle 10 is a portion 12 provided with a pocket 13"from Whichextends able :head 15 the shank 16 of which is tapered as shown and having a plunger extension 17 received in the handle bore 14, a spring 18 mounted in the borebetwe'en the end thereof and the plunger 17 yieldingly pressing the head 15 axially of the pocketed member 12. The pocketed member 12 has a slot 19 through which travels a pin 20 secured to the shank 16 whereby the head 15 may be conveniently moved into a desired position against the spring 18. f The pocketed member-12m provided with a lower earportion 21 to which is pivotally connected the head 22 by means of the pivot pin 23. The head 22 has a'channelle'dshank' portion 24L which receives thehead15. The head 15 has the jaw p'ortion'25, andthe head 22has the jaw portion 26. The jaws 25 and26are constructed so as to constitute at their'lower ends a socket, each jaw being formed of two angularly disposed toothed or flat walls 27 and 28, the upper parts of the jaws having plane faces with fiat or toothed surfaces as may be desired, these faces being. designated by the reference character 29 inFigs. 2. and 7 By this con struction of the jaws, it is evident that the wrench may be used for bolt heads, nuts and the like, and also for round bolt shanks, pipes, and the like.

It will be obvious "that it is very easy to apply the wrench to the work, it being necessary only tomove" the head 15 by the pin 20 against the spring 18 until the jaws are wide enough to embrace the boltor nut, as the case may be, and then to release the pin 20 and permit the spring 18'to forcethe head 15 against the work whereupon the head 15 may be secured in position by the means which will presently'be described.

The pocket 13 of the member 12 has two lower walls 30 and 31 which are arranged as shown preferably at right angles to each other, these walls forming the outline of a recess into which is placed a tapering lock above description.

ing key 32 operated by a screw 33, the key and screw being clearly shown by Figs. 2 and 6. The screw 33 passes through a threaded opening 34: in the wall 31 and has a shoulder which bears on the face a, of the key 32 to force the key into engagement with the tapered shank 16, and a ball point 35 which is received within a recess 36 in the key '32'to withdraw the key from engagement with the shank when the head 15 is to be readjusted. The surface 6 of the key 32 is at right angles to the surface a, and the key is thus guided by the walls 30 and 31. lVhen the screw 33 is turned to force the key 32 into engagement with the shank 16, the surface I) of the key is guided by the wall 30, and inasmuch as the wall 31 is at right angles to the wall 30 and parallel to the surface a of the key, the pressure of the screw on the key is exerted normally of the surface a and maximum screw turning force is thus imparted to the key.

The construction and manner of manipulating the wrench is apparent from the In brief, the wrench comprises the pocketed member or housing 12, the slidable head 15, the pivoted head 22, andthe locking device comprising the key 32 and the screw 33. To adjust the wrench it is necessary only to withdraw the key 32 from engagement with the shank, to move the head 15 against the spring 18 until the jaws are properly spaced, to place the jaws in position to embrace the work, releasing the slidable head to permit the spring to force it snugly against the work, and then to tighten the slidable head in position by turning the screw 33 to force the key 32 into locking engagement with the shank 16. From the drawings, it will be noted that there is a slight space 37 between the shank 24 of the head 22 and the housing 12 to permit a small amount of free movement of the head 22 to take care of irregular sized bolts or heads, and also to permit of quick disengagement of the wrench from the work.

It is apparent that the wrench may be quickly applied and removed from the work and is very convenient in manipulation. By reason of the novel holding device of the slidable member, an adjustable wrench is provided and at the same time all the advantages'of a wrench of the fixed head type are preserved. The holding device cannot be moved from adjusted position except by v operation of the screw, and the greater the wrench turning stress, the greater is the resistance offered by the holding key to movement of the slidable head.

In view of my disclosure, certain changes in the construction and arrangement of parts may be made without departing from theinvention, and it is to be understood that this disclosure while being illustrative of the best mode of embodying my invention is not to be considered as limiting the inven tion thereto, but any changes that come within the scope of the appended claims are to be considered as partof this invention.

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

1. A wrench comprising a stationary member having a longitudinal bore and a recess in communication with said bore, a longitudinally movable member having a tapered shank slidable in said bore over said recess, a head pivoted to said stationary member at a point below said tapered shank, a tapered locking key within said recess and cooperating with said tapered shank for holding the latter in rigid adjusted position with respect to said stationary member, and a screw bear ing on said locking key for holding same against said tapered shank.

2. A wrench comprising" a stationary member having a longitudinal bore, and, a recess in communication with said boreysaid recess having two walls at right angles to each other, a longitudinally movable member having a tapered shank slidable in said bore over said recess, a head pivotally con.- nected to said stationary member, and a tapered locking key within said recess and cooperating with said tapered shank to hold the latter in fixed adjusted positionwith re spect to said stationary member, said locking key having two faces at right angles to each other complementary to the "right angular faces of the recess.

3. A, wrench comprising a stationary member having a longitudinal bore and a lateral extension having a recess therein communicating with said bore, av movable member having a shank portion slidable in end of, said shank and urging the shank" in a direction outwardly of said bore, a head pivoted to said stationary ineinberat a point below said tapered shank, a tapered locking key within said recess and cooperating with said tapered shank for holding the'lat-ter in rigidadjusted position with respect to said stationary member, and a screwbearing on said locking key for bold ing same against said tapered shank;

5. A wrench comprising a stationary memv her having a longitudinal bore and a lateral for holding the latter in rigid adjusted rela- 10 extension having a recess in communication tion.
