Spec'iiicairlon of Letters'latent.

Patented May 4, i915.

' Application filed October 26, 1914. SerialNo. sea-70a.

To all whom it may concern.

Be it known that 1, WILLIAM KAYLOR, a citizen of the United States, residing at Muskogee, in the 'countvof Muskogee and State of Oklahoma, have invented a certain new and useful Improvement in Wrenches; and I do declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to wrenches of the spanner type.

The object of the invention is to provide a simple as well as cheap nut wrench, in the use of which it is not necessary to bodily remove the wrench from the nut on each reverse stroke, and which may be quickly and easily applied to the nut and when so applied, will have a powerful bite or purchase thereon so that all slipping will be we vented.

is shown composed of a handle 1 with similarly constructed heads 2 and 3 at its opposite ends, all of which are constructed in a single piece and of any preferred material.

The heads 2 and 3 while alike in -'construction, are preferably of diiferent sizes to adapt them for use on nuts of different sizes but one only will be described in detail. Each head is constructed with two arms or jaws 4 and 5 of integral construction and of substantially the same length. The two jaws form a socket between them which. is adapted to receive the nut, one side wall of said socket conforming in shape to two contiguous facets of a hexagonal nut. According to this invention, the armor jaw 4 is formed with an active fiat face 6 which extends in a plane lying oblique. to the handle 1 and engages one facet of a nut N when the wrench is turned in gripping operative position. This face is considerably longer, being tuse angle between the two faces 6 and 7' corresponds to the angle of two adjacent facets of the hexagonal nut N and is designed to engage said facets when the wrench is turned in position for reversing.

The arm or jaw 5 has an active face 9 .of a length equal tothe length of one facet of the nut on which it is designed to be used.-

This face 9 diverges outwardly in respect to the 'Eace 6 and is connected at its lower end with the lower end of said face 6 by a transverse nut engaging face 10 of-a length corresponding to the lengthof theface 9. A face 11 lying parallel to the face 6, extends from the upper end of the face 9 and is one-half as long as the faces 9 and 10 or one-half as long as the facet of the nut to be engaged. This face 11 merges at its upper end into. an obliquely disposed face 12 disposed at the terminal of the jaw 5 and forming an angular projection 13 which, when the nut is engaged by the wrench, is positioned midway the length of one of the facets thereof,

see F ig; 1, and when in engaging position, the faces 6, 10, 9 and 11 engage four of the facets of the hexagon nut and thus provide a reliable engagement of the wrenchwith the nut to action.

prevent, slipping during the turn- 1n in the foregoing description, I have de vscribed specifically all parts with which the wrench is equipped but itwill be obvious that the salient features thereof are, a rigid "jaw having a. flat inner face one and onehalf times as long as a facet of the hexag0- nal nut, a second jaw having'a fiat inner face lying arallel to the first mentioned face and being one-half as long as a facet of the nut, the face 7 also being one-half as long as a facet of the nut, and furthermore, 7

that the various active faces of the wrench are all parallel to the facets of the hexagonal nut, these features being all essential,

lie

when the wrench is applied to use as seen in Fig. 1 and the lower. end ofits handle is moved to the right, thereby loosening the nut N, said wrench may be pulled downwardly to an extent slightly greater than that seen in Fig. 2, during which movement the fiat face 6 of the rigid jaw 4 slides upon one facet of the nut N until the face 7, contacts with said end, thus limiting the movement of the wrench and moving the face 11 downwardly from engagement with the nut. It is then possible to move the wrench handle again to the left to again grip the nut, it being therefore seen that although no ratchet is employed, the wrench produces the results obtained by the usual ratchet wrench.

I claim as my invention A wrench including a one-piece head having laterally spaced jaws with a hexagonal nut engaging socket therebetween, said socket comprising two flat converging nut facet engaging faces running parallel and of equal length to two of the faces of the nut to be engaged, one of the spaced jaws having a flat inner face one and one-half times as long as one facet of the nut, the lower end of said jaw converging with the outer end of the adjacent facet engaging face of the socket, a stop one-half the length of the facet of the nut, extending parallel withthe facet and projecting from the outer end of said jaw, the other spaced jaw being parallel with the first-named jaw and having a flat inner face one-half the length of the facet of the nut, the inner end of said face converging with the outer end of the adjacent facet engaging face of the socket, and the other end projecting obliquely outward from the face, whereby the various inner faces of the wrench are parallel with the facets of the hexagonal nut, and one face of said wrench being one and one-half times longer than the facet of the nut and its opposite parallel face being one-half the length of the opposite parallel facet of the nut substantially as described and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

WILLIAM KAYLOR.
