NUT WRENCH.

Application filed July 23,

Our invention relates to wrenches, and more particularly to nut wrenches of the self-adjusting type, that are adapted to readily engage nuts of various sizes and configurations, or even those of a smooth or round construction.

The object of the invention is to so construct the same that it will be simple, durable, will have few parts, will be eflicient in operation, and can be readily handled.

In the drawings forming a part of this specification, and in which like symbols of reference represent corresponding parts in the several views Figure 1 is a perspective view of the preferred form of our wrench;

Figure 2 is a detail view of the jaw portions of the same showing the inner and outer sides of the detachable portion;

Figure 3 is a detail of the parts of a modification illustrating both sides of the detachable portion;

Figure 4: is a perspective of a further modification showing an enlarged gripping jaw and a slot for the pivot;

Figure 5 is a modification for use for a smooth nut or pipe showing a serrated edge and separable locking clutch;

Figure 6 is another modification of the gripping element similar to Figure 4, but

without the slot 16; and,

Figure 7 is a slightly modified form of Figure 6 showing the gripping surface forming a complete section of the jaw.

In the drawings the numeral 1 represents the jaw forming loop or head or portion of the wrench for grasping the article to be operated upon; 2 a channel formed in the inner surface of the wrench; and 3 a lug or jaw formed integral with the handle and adapted to rest in the channels 2, which form a bearing for the same, the jaw 3 being the same width as the jaw forming loop. When the handle is turned on its pivot the lug 3 will grip the article which rests within the jaw l. 4 is a curved shoulder formed on the inner end of the wrench handle. 5 is a detachable side or segment of the wrench; and 8 the handle of the same. At 9 are shown reversed views of a detachable section of the wrench-head producing extensions of the wrench sides for assembling and pivoting the wrench to the handle; 10 perforations in the extensions forming a bearing for pin 7 1925. Serial No. 45,529.

for assembling the handle and jaw; and 11 designates the limits of the cut-away wrench segment. 12 are the holes throughthe segment of the wrench and the adjacent hole of the detachable wrench extension for binding more securely the two parts together by means of bolts, or the like. 13 is a hole in the handle for hanging up the device.

14 is a lug on the extension or supporting member and a removable member, and 15 curved lugs on the handle which pivot and operate in conjunction with said lug l4, lugs or protrusions 15 resting upon the upper side of lugs 14: and working thereon.

In Figure 4 are slots 16 in the extension, within which are adapted to operate a pin 17 on the handle. 5 is the gripping extension on the wrench handle, the same operating in the cut-away portion in the jaw. This cut-away portion of the jaw permits ample movement of the gripping surf-ace 3 of the handle, and allows reasonable play of the journal 17 within theslot 16 to facilitate the operation of the gripping action.

In Figure 5 is illustrated a form adapted to operate on a smooth or round surface, the same having teeth 19, and a separable locking clutch 20, by means of which it may be readily operated by opening or closing the same, thus facilitating its use. 3 denotes the serrated extension or gripping portion of the handle, and 22 pivots. The serrated gripping portion 3 of the handle grips the nut when the handle is operated, there being suflicient space between said serrated portion and the lower cut-away portion of the wrench jaw.

Figure 6 illustrates a form similar to Figure 4, but without the slot in the same.

Figure 7 shows the gripping portion of the handle forming a complete section of the jaw, and permitting a free movement of the same.

The instrument illustrated in the various of the wrench, a handle providing a gripping head or movable jaw with a face approximately as thick as the opposing jaw of the loop, and a shank portion of less thickness than said face, the loop or head being cut-away to receive said shank with its thickened jaw Within the loop or head, and means securing said handle movably to said cut-out portion of the loop or head.

2. A wrench, comprising an article inclosing' head or loop, providing one jaw of the wrench, a handle providing a gripping head or movable jaw with a lace approximately as thick as the opposing jaw of the loop, and a shank portion of less thickness than said face, the loop or head being cut-away to receive said shank with its thickened jaw within the loop or head, a detachable portion secured to the loop or head to lap said shank and maintain it in the cut-away portion, and means securing said handle movably between said detachable portion and the cut-out portion of the shank or head.

3. A wrench such as defined in claim 1 in which the handle has a pivoted movement about its securing means.

4. A wrench such as defined in claim 1 in which the handle has a sliding movement on its securing means. I

5. A wrench such as defined in claim 1, which has both a pivotal and sliding movement.

In testimony whereof we affix our signatures.
