SIDNEY COOK, OF ORLANDO, FLORIDA, ASSIGNOR OF ONE-HALF TO EZRA F.

SPERRY, OF SAME PLACE.

WRENCH.

SPECIFICATION forming part 0f Letters Patent No. 401,819, dated April 23, 1889. Application filed September 29J 1888. Serial No. 286.744. (No modell To all whom t 'may concern:

Be it known that I, SIDNEY COOK, of' Or lando, in the county of Orange and State of Florida, have invented a new and Improved Wrench, of which the following is a full, clear, and exact description.

My invention relates to an improvement in wrenches, and has for its object to simplify the construct-ion of the same and provide a means whereby one jaw will be removable and adjustable, and wherein the movable jaw may be placed at various angles with respect to the fixed jaw and adjusted laterally while 1n any position.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is t0 be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure l is a side elevation of the wrench partly broken away, illustrating the jaw as in a vertical position in positive lines and as carried to its downward position in dotted lines. Fig. 2 is a transverse section on line a; .fr of Fig. l, and Fig. 3 is a side elevation of the movable jaw inserted in the body at the side instead of at the top.

In carrying out the invention the body of the wrench consists of a handle, l0, and a shank, 1l, inserted in said handle in any approved manner, to which shank, at or near the upper end, the side pieces, l2, are riveted or otherwise fastened in such manner that the outer face of the shank will bc fiush with the outer face of the sides, as best illustrated in Fig. l.. The side pieces, l2, are preferably wider at the top than at the bottom, and are united at the top at one side by being rigidly secured to a fixed jaw, i3, the said jaw being provided with teeth la uponthe uppersurface, and teeth 15 upon the outer edge, as best illustrated in Figs. l and 2.

VThe upper toothed surface of the fired jaw is preferably inclined from the outer edge inward and the outer toothed surface is slightly concaved. The said concaved surface may, however, be dispensed with and the outer edge be inclined from the top downward and inward, if in practice it is found :more desirable. y reason of the attachment of the side pieces to the shank and to the fixed jaw, a space, 16, is made to intervene the opposing inner faces of the said sides, whereby the detachable jaw 17 may be freely moved up or down between the sides.

A circular carrier, 18, is fitted in eligning apertures in the sides l2, near the top, and the said carrier is held between the sides free to revolve by reason of a rabbet, 1S, being formed in each side near the periphery, in which rabbet the surface of the sides l2 surrounding the apertures is fitted, as bestillustrated in Fig. 2. In placing the carrier in position the reduced sides are passed through the apertures in the sides of the body prior to the said sides being attached to the fixed jaw 13.

A rect-angular recess, 20, is made in the carrier 18, extending through from face to face, and in the periphery a similar recess is made, extending diametrically through from edge to edge, with an enlargement forming a recess at or near the rear lower wall of the diainetrical recess for the recept-ion of the upper end of a spring, 2G, hereinafter described. rIhe latter recess intersects the rectn angular recess 20, which is preferalily located at the center of the carrier.

The aperture 2O is made of a rectangular contour throughout, or only at the outer face, the side walls in which latter event may be concaved, as best shown in Fig. 2. The recess 20 is adapted for the reception of a circular nut, 2l, which is interiorly threaded and preferably exterior-ly serrated, the nut being of sufficient diameter to permit of its cXtending slightly beyond the face of the carrier, when located vin the recess, to facilitate manipulation.

The movable jaw 'i7 consists of a shank, 22, provided with a broken thread, 23, and curved or parrot-bill head 24, the under surface of which head is eoncaved and toothed, as best illustrated at 25 in Figs. l and 3.

For ordinary purposes the shank 22 of the removable jaw is introducedinto the diametn rical recess of the carrier and into the nnt2l,

IOO

revolving in the transverse recess 20, whereupon, by the manipulation of the said nut, the head 24 may be made to approach the upper toothed surface, 14, of the iixed jaw as near as may be desired. Vhen the movable jaw is thus introduced into the body of the Wrench, it is held in a vertical position and against the inner face of the fixed jaw 13 by means of a spring, 26, attached to one edge of the shank, at the rear,below the space 16, the upper end of the said spring being made to enter a recess in the periphery of the carrier at or near the rear lower wall of the dialnet-- rical recess produced therein.

The jaws may be accommodated to articles of Various sizes by carrying the movable jaw downward in direction of the arrow in Fig. lagainst the leverage of the spring 26. I/Vhen the end of the spring leaves the said recess in the carrier, itimpinges against the carrier, holding the said jaw rigidly in any position at an angle to the iXed jaw in which the said movable jaw may be left by the operator, and at what-ever angle the movable jaw is placed, as the carrier follows the movement of the jaw, the same may be freely adj usted through the medium of the nut 21 either to or from the Xe'd jaw, as desired.

In the event that the wrench is to be used upon pipe or a similar article, the movable jaw is detached and the carrier revolved so that the diamet-rical recess therein, which has heretofore been vertical, will assume a horizontal position or a position transversely of the body. When this is accomplished, the end of the threaded shank 23 is introduced in the space 16, below the outer edge of the fixed l jaw, into the said diametrical recess, and into the nut, assuming the position illustrated in Fig. 3.

In adjusting the movable jaw to articles of various sizes the head is carried downward, as indicated by the arrow of Fig. l, the fine adjustment being accomplished, as heretofore stated, through the medium of the revolving nut 2l.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a wrench, the combination, with a body open at the top and sides and provided wit-h a fixed jaw having teeth on its upper and outer faces, of a revolving carrier in the body and a movable jaw detachably and adj ustably secured in the said carrier, substantially as described, whereby provision is made for causing the movable jaw to work with either toothed face of the fixed jaw, as set forth. A

2. In a wrench, the combination, with an open body provided with a fixed jaw having teeth on its upper and outer faces, of a carrier fitted to revolve in the body and provided with apertures intersecting each other at right angles, a nut fitting in one of the apertures of the carrier, a movable jaw having a screwthreaded shank and passing through the carrier and nut, and a spring secured to the body and engaging the carrier, substantially as herein shown and described,

SIDNEY COOK.
