FREDERICE SCHNEIDER, OF VELVA, NORTH DAKOTA.

WRENCH.

To all whom it may concern:

Be it known that I, FREDERICE SCHNEIDER, a declared citizen of the United States, residing at Velva I). O., in the county of Mc- Henry and State of North Dakota, have invented new and useful Improvements in IVrenches, of which the following is a specication.

The invention relates to an improvement in wrenches, being more particularlyv directed to a wrench construction in which the jaws will readily accommodate themselves to articles of various sizes. l

The main object of the present invention is the provision of a wrench in which the sliding jaw is operated with relation to the fixed jaw by the handle, so that in the movement of the handle in one direction the sliding jaw is moved toward the fixed jaw to operate with the article while in the movement of the handle in the opposite direction the handle is moved to release the article.

The invention in its preferred details of construction will be described in the following specification, reference being had particularly to the accompanying drawing, in which:--

Figure 1 is a view in elevation of the improved wrench. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a vertical section, partly in elevation, of the wrench, the handle being broken off. Fig. 4L is a perspective view of the movable jaw.

Referring particularly to the accompanying drawing wherein are shown the preferred details of construction of the improved wrench, 1 denotes the wrench body formed to provide spaced parallel plates 2 and 3, approximately of semicircular shape in elevation and connected at one end of the diametrical edges by a projection 4L which will be hereinafter termed the fixed jaw. This jaw is o-f a thickness corresponding to the maximum distance between the relatively outer surfaces of the plates 2 and 3, and its inner edge, which forms the operative face of the jaw, projects at right angles to the upper plane edges of the plates. The relatively inner surfaces of the plates, throughout their maximum dimensions and in alinement with their upper edges, are formed with grooves 5, for a purpose which will presently appear.

The movable jaw comprises a member including a jaw proper 6, corresponding in size and shape with the xed jaw, which Specification of Letters Patent.

Application filed October 30, 1909.

Patented May 24, 1910.

Serial No. 525,434.

jaw 6 is secured upon or integral with a guide bar 7 underlying the jaw G and having a length corresponding to the maximum dimensions of the plates 2 and 3. The guide bar 7 is of cruciform shape in cross section, the side ribs 8 of which are designed to be guided lin the grooves 5 of the plates 2 and 3, and an upright 9, slidably fitting between the grooves, will be plain from Fig. 2.

A handle 10 is pivotally connected at 11 to the body 1, said point of connection being central of the body at the lowest point thereof. The upper end of the handle, which rests between the plates 2 and 3 of the body, is formed to provide a rounded head 12 designed to engage a rounded aperture 13 formed in the guide bar 7 of the movable jaw. By moving the handle on its pivot it will be obvious that the movable jaw may be adjusted toward and from the fixed jaw as desired, the guide bar during such adjustment moving transversely of the body, as will be plain from Fig. 3.

The spaces between the plates 2 and 3 of the body between the guide bar opening and the handle opening are preferably closed, the curved edges on one side being united by an integral strip 14:, and on the other side by a spring plate 15 fixed at the lower end and free or movable at the upper end. The upper end of the spring terminates immediately beneath the lower edge of the guide bar when the latter is in position, and the spring serves to permit the movement of the handle so as to carry the upper end thereof wholly beyond the plane of the guide bar, to permit the complete removal of the movable jaw when desired. In this movement of the handle the upper end displaces the free end of the spring, as is necessary owing to the relative sizes of the parts, and upon the restoration of the parts to normal position, the spring plate again closes the opening.

It is, of course, to be understood that while the invention is illustrated as a nut wrench it is equally advantageous as a pipe wrench or a pipe cutter, in which, in different instances, the respective jaws 4: and 6 are to be appropriately formed. Therefore I contemplate the use of any type of jaw which may be necessary or suggested by the particular work in hand.

It will be obvious that by moving the handle in one direction the movable jaw will be caused to approach the fixed jaw, clamping any desired object therebetween,Y the reverse movement of the handle separating the jaws to release the object.

Having thus described the invention, what j spaced plates, a jaw formed integrally with the body and projectingy above the plates, amovable jaw including a jaw proper and a guide bar of cruciorm shape,r said plates being formed with grooves to receive the guide bar, and a handle pivotaflly mounted between the plates and terminally engaging the notch in the guide barn 2. A wrench inclu-ding a body comprising spaced plates,

a jzaw formedv integrally with VAtheibody and projecting above the plates, a

movable jaw inclu-ding a jaw proper and a guide bar ofV cruciform shape, said plates being formed with grooves to receive the guide bar, a handle pivotally mounted between. the plates and terminally engaging the notch in the guide bar, and a spring secured at one end o-f' the plates to close the space between the handle and guide bar.

In testimony whereof I atlix my signature inpresence ofV two witnesses.
