SPECIFICATION forming part of Letters Patent No. 777,389, dated December 13, 1904.

Application iiled August 29, 1904.

To all whom, it may cm1/cern:

Be it known that l, Josnrrr N. NOYER, residing at Gould City,in the county of Garfield and State of Washington, have invented certain new and useful Improvements in Wrenches, of which the .following is a speeilication.

This invention relates to certain new and use ful improvements in wrenches, and particularly relates to the class of ratehet-wrenches having means for so adjusting the ratchet connection that the wrench may be used either as a ratchet-wrench or as an ordinary turnwrench.

My invention also includes a pair of jaws so arranged as to be simultaneously moved toward or from the axial line of rotation of the ratchet-Wheel.

My invention is also in the nature of an improvement on my Patent No. 757, 764, of April 19, 1904.

With other objects in view, which will be hereinafter apparent, the invention also in-` cludes certain novel arrangement and combination of parts, all of which will he first described in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which-,

Figure l is a perspective View of my invention. Fig. 2 is a side elevation of a portion thereof. Fig. 3 is a vertical longitudi- Fig. 4 is a vertical section on the line 4 4 of Fig. 3. Fig. 5 is a detail perspective view of the ratchet-wheel. Fig. 6 is a similar view of the jaws. Fig; 7 is a detail cross-section on the line 7 7 of Fig. 3.

Referring now to the accompanying drawings, in which like characters of reference in-4 dicate like parts in all of the iigures, l designates the lever member, whose lower end 1*L is flattened and apertured, as at 1b, to receive a stub-shaft QLof the ratchet-wheel 2 and held in place by a pin 2m, as shown. To the other extremity of the lever l the handle portion lcis attached (see Fig. l) in any suitable manner. The ratchet-wheel 2 includes a stub-` shaft 2, a ratchet portion 2b, and a jaw-carrying disk portion 2", on the front face of which the jaw- guides 2d 2 are formed, and these guides Q Ql'are provided with grooves Serial No. 222,617. (No model.)

2e 2e and are so arranged with respect to one another as to form a Tsslot 2g' for a purpose presently understood. `The ratchet portion 2h and the disk portion E2 are so arranged with respect to one another as to form a circumferential groove 2 to receive the lip 3 of the pawl-carrier 3, hereinafter again referred to. The jaws 4 4 are provided with a threaded bore 4 and grooves 4" 4" in its side faces, which grooves 4" 4l form a T-head 4 to fit and operate in the T-slot2.g of the ratchet member E2.

5 designates a turn-screw having the :reversely-threaded portions 5 5", and the said screw 5 terminates in the squared ends 5", to which the milled heads 6 6 are secured.

7 7 designate screw-plates pivoted over the ends 5C of the screw 5, and these plates 7 7 are provided with an, aperture to allow free turning of the screw. The plates 7 7 are secured to the ratchet member 2 by the screws or pins 7 7, as clearly shown in Fig. 7.

The pawl-carrier 3 comprises a housing having its bottom provided with a squared aperture 3'" to receive the pawl 8, having a rod 8"'. This rod 8 extends through an aperture-3h in the top of the carrier 3 and is provided with a stop-pin 8, as shown.

3l designates a transverse slot in the upper portion of the carrier 3 to receive the pin 8", and 3e designates a second slot of a similar nature located at right angles to the slot 3 for a purpose presently understood.

9 designates a spring surrounding the rod 8 and held between the pawl 8 and the top of the pawlcarrier and within the housing to normally hold the pawl 8 in engagement with its cooperating ratchet 2b. y

3 designates an apertured lip on the pawlearrier, through which and the lever l the securing bolt or screw a' passes.

The pawl-carrier 3 and the lever l are also formed with ears 3X lX to receive the securing-screws y, as shown.

turning it through an angle of one hundred and eighty degrees and .then allowing the i spring to press the pawl 8 into its ratchet-engaging position again the wrench will operate as a ratchet-wrench, but will turn the jawcarrier in the direction opposite that'shown by the arrow in Fig. 4.

To use the wrench as a simple turn-wrench, it is only necessary to turn the rod 8 through an angle or' ninety degrees from the position shown in Fig. 4, when the beveled portion 8 of the pawl 8 will be at right angles to the position shown in Fig. 2, bringing the parallelside faces of the pawl 8 (which is square in cross-section) so that they will engage the ratchet at both sides of the pawl, and thereby prevent a ratchet movement between the lever and the jaw-carrier.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation, and many advantages of my invention will be readily understood by those skilled in the art to which it appertains, and I desire it understood that slight changes in the detail construction and arrangement of parts may be made without departing from the scope of the invention and the appended claims.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
