JAMES L. SCROGGINS, SHERMAN, TEXAS, ASSIGNOR OF ONE-HALE To A. S. WALDROP, OF SHERMAN, TEXAS COMPOUND TOOL.

Application filed May 21, 1912, Serial No. 698,734. Renewed February 11, 1913.

To all whom it may concern.

Be it known that I, JAMES L. Sonoccrns, acitizen of the United States, residing at Sherman, in the county of Grayson and State of Texas, have invented certain new and useful Improvements in Compound Tools, of which the following is a specification.

In its broader aspect, the object of this invention is to provide a compound tool of the wrench type, the several parts of the construction of which so cooperate as to permit of a wide range of usage of the device.

As is well known, even under ordinary conditions of work, a mechanic requires two different species of wrenches which, for the purpose of diiferentiation, I herein term a nut-wrench and a pipe-wrench. To prevent the necessity of duplicating these tools, it has been my object to combine their features in a single device and to this end it is contemplated to provide in my invention a stationary, a detachable, and a pivoted jaw member, the latter co-acting normally with the detachable jaw member to hold the same in operative position when using the wrench particularly as a nut-wrench, and being susceptible of movement into a predetermined position to cooperate with the stationary jaw member for use as a pipe wrench.

A still further object of my device is to provide a wire cutting element on the shank whereby wire may be severed by the pivoted jaw member, and with the above and other objects in View, this invention consists of the construction, combination, and arrangement of parts, all as hereinafter more fully described, claimed and illustrated in the accompanying drawings, wherein,

Figure 1 is a View in side elevation of a wrench constructed in accordance with my invention; Fig. 2 is a front view of the same; Fig. 3 is a rear view; Fig. 4 is a horizontal sectional View of the detachable jaw; Fig. 5 is a view in elevation of the wrench, showing the cooperation of the pipe jaw, the detachable jaw member being omitted to show more clearly the interlocking parts therefor; and Fig. 6 is a perspective view of the detachable jaw.

Throughout the following detail description and on the several figures of the drawings, similar parts are referred to by like reference characters.

Specification of Letters Patent.

Serial No. 747,799.

Specifically describing my invention, 1 designates the shank of a wrench having one end thereof,-designated as 2, constituting the usual handle. The shank 1 terminates at its other extremity in the fixed or stationary jaw member 8, which member performs a dual function, as will hereinafter be more fully set forth.

4: designates a detachable jaw member which, when in operative position, constitutes an off-standing member having formed on its inner side the spaced locking members 5 which are adapted to receive therebebetween the T-shaped lug or projection 6 which is formed on the inner side of the stationary jaw member 3. The jaw member 41 is furthermore formed at one end with the bifurcated portion 4 between which is received the projection 7 formed on the stationary jaw member 3 adjacent the shank 1 of the wrench. The bifurcated portion 4: is cut away preferably at one side to conform to the recessed portion 8 on opposite sides of the shank 1 and when thus constructed the detachable jaw member is held from lateral displacement in the use of the invention, it being understood that as just described the device constitutes a nutwrench. The jaw member 4 when in operative position, at its outer end, is spaced from the fixed or stationary jaw member 8 so that the nut may be received in the opening 9. It is only necessary in positioning the detachable jaw member A to slide the same longitudinally of the wrench in such a manner that the T-shapedi projection 7 is received into the opening between the spaced locking members 5 which conforms to the shape of said projection 7.

The shank of the wrench on the side opposite the stationary jaw member 4 is cut away on both sides of the wrench so as to form recesses therein and near the outer portion of the recesses which form a reduced edge 10 is pivotally mounted the pipe jaw member 11. The jaw member 11 is formed with spaced side members 11 through which the pivot 12 passes when mounted on the shank 1 and said members 11 are curved at their opposite extremity, where they are also connected by means of the end portion 13. At a suitable point on the edges of the side members 11 of the pivoted jaw member 11 are provided the lugs 14 which are adapted to lockingly engage in notches 15 formed in the bifurcated end portion 4' of the detachable jaw member 4. When thus engaged, the detachable jaw member 4: is positively held in position and a spring actuated projection 16 is mounted in the recessed portions of the shank 1 so as to project therefrom into engagement with a side member 11 on the opposite side to the lugs 14 and by this means the pivoted i v membe i p even e rom beeem i iserg ged fr m th de a habl jaw memt is ntemp at that a umb o jaw m m s 4 a to he nrevie d fo a w eath each of aid new m be s bein at similar e e tr e ier bu f rmed in 1 amanner that the opening 9 will be of difterent es eerdin'e to h euete ry si if ra w th.

The inner edges of the curved porea firs m n i n a W ll as e n d eat remity 3', are preferably serrated in order to facilitate the gripping action on the bjec w h s te'be'ei r Or nserewed- The reduced edge 10 is suitably formed with a notch 17 at a point near the pivot 12 f he me'v ble jaw m e Said not constituting a wire cutting element. When desired to sever a piece of wire the jaw 11 is swung outwardly and said Wire inserted in the notch 17, and by movement of said jaw toward the shank of the wrench, the wire will be easily cut in an obvious manner.

It is further contemplated that the top or. outer side of the detachable jaw member a be formed with a V-shaped recess 18, the edge portions of which are undercut and the function of said recess is to permit a nail to be withdrawn when the head of the latter is inserted in said recess, the shank of the wrench acting as a lever. A second recess. 19 is also provided on the jaw memher 4, so formed as to have a pointed projection 19 therein, and the purpose of this recess is to provide a simple means for. with draw ng s p s th ke There are numerous advantages of my particular construction of wrench, among which may be mentioned the elimination of thescrew actuated sliding jaw found in ordinary constructions of monkey wrenches which are always, subject to wear and rust, The device also serves for perrmin umero s. n ions as dise esed the description and much expense may be saved by the same from a manufacturing standpoint.
