SPECIFICATION formingppart of Lettersratent No. 735,734, dated kAugust 1.1, 190s; lAmilicatio'n filed-September 19. 1900.' Serial No, 30,499. (No model.)
To @ZZ whom, it' may concern,.- v
Beit known that I, CLARENCE C; ENGLISH, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Wrenches, of which the following. is a' specification.
My invention relates to Wrenches; and my object is to provide a strong and simple tool composed of loose parts without rivets or other connecting devices, which can be cheaply constructed, is easily and accurately adjusted, and firmly locked in adjustment.
My wrench comprises a lixed jaw, which also forms the handle, a sliding jaw having a sleeve inclosing the fixed jaw and movable thereupon, and a locking-cam having a bearing in said sleeve and provided with a toothed or milled edge which engages with a correspondingly-formed surface on the fixed jaw.
The invention is illustrated in the accompanying drawings, in which- Figure lis a perspective view of the wrench. Fig. 2 is a side elevation, broken away to show partsin longitudinal section. Fig. 3 is a crosssection on line .fr with the jaws locked by the cam. Fig. 4t is a similar cross-section with the jaws released, in position for sliding adjustment. Fig. 5 is a perspective view of the locking-cam.
A represents the handle of the wrench, formed withthe fixed jaw B. The surface of the handle adjacent to the jaw and for the whole or a sufficient part of the length is formed with. a concave channel which is toothed, threaded, or milled, as showngat a.
C represents the movable jaw whichY is formed as a part of the sleeve D, which is fitted to a rounded edge g and the sides of the handle, leaving a space adjacent tothe channel ct. This space formsv a bearing for the locking-cam E, which has a toothed, threaded, or milled surface corresponding to that of thev channel. The end of the cam abuts against a shoulder c of the jaw C. The cam has a -handle C', which when the parts are assembled projects through a slot cl of the sleeve, with a close lit in the slot. In assembling the parts the cam is slipped into the sleeve and the handle allowed to drop through the slot, as in Fig. 4. The sleeve is then placed upon the handle, and as the fiat face e of the cam is adjacent to the channel a the sleeve can be moved freely upon the handle. The parts are locked by turning the cam to the position of Fig. 3, causing its milled surface to engage and bind strongly in the channel c, thereby drawing the sleeve and handle tightly together. The edge of the cam is dressed off slightly, as shown at f, to insure a proper engagement of the milled sur- A faces, the milling continuing, however, at the same depth around the dressed-off corner. The ease of operation 'as to adjustment and locking will be apparent, since it is only necessary to turn the cam to position of Fig. 4 in order to-render the jaws freely adjustable. It will also be observed that no screws or rivets are employed, the parts being loosely assembled and being self holding and locking. A stop may, however, be used on the handle, if desired, to keep the sleeve from being entirely separated from it. In ordinary use,
however, I have n ot found such a stop necessary.
The strength ofthe device will also be noted, and particularly the manner in which the shoulder c abuts against the solid cam. The
sleeve is preferably made substantially ellip-v tical in cross-Section, and the channel in the upper edge of the handle forms substantially a circle withthe upper end of the ellipse. In this manner when the cam is rotated between the handle and the sleeve to lock the jaw the sleeve is tightly bound at top and bottom, and as the sides fit snugly against the sides of the handle andthe shoulder c abuts against the end of the cam all lost motion -is taken up and the parts are held absolutely rigid, and thus the greatest strength is .secured when using the wrench. j, .I
Having thus fully described my invention, what I claim as new, and desire to'secure by Letters Patent, isl l. A wrench comprising a handle, the lower edge of which is rounded and the upper edge is provided with a milled channel extending longitudinally thereof,` one end of the handle being provided with a rigid jaw, a slotted sleeve on the handle, substantially elliptical in cross-section, the forward end of which is' provided with a rigid jaw, the channel of the ICO handle forming with the upper side of the sleeve a substantial circle, a segmental cam between the handle and the sleeve, provided with a handle which projects through the slot in the sleeve, a portion of the surface of the cam opposite the projection being provided with teeth for engaging with the milled channel when the cam is rotated into its locking position.
2. A Wrench comprising a handle, one end of which is provided with a rigid jaw, and its upper edge is provided with a concave milled channel extending longitudinally thereof, a sleeve on the handle, one end ot' which is provided with a rigid jaw, and the other end is slotted and has the inner portion recessed, the wall of the recess forming a shoulder at one end and being concave to correspond with the curvature of the channel, and a substantially cylindrical cam in said recessed portion, a portion of the surface of which is provided with teeth to engage with the milled channel when in its operative position, said cam being provided With a handle intermediate of its ends, which projects through the slot of the sleeve, the distance of the projection from one end of the cam being suchthat said end will be held firmly against the shoulder in the sleeve at all times.
3. A wrench comprising a handle, one end 5o of which is provided with a rigid jaw, and its upper edge is provided with a milled channel extending longitudinally thereof, a slotted sleeve on the handle, one end of which is provided With a rigid jaw, and the inside of the 55 .slotted portion is recessed longitudinally,
