COMBINED WRENCH AND PLIERS.

Specification-of Letters Patent.

Patented July 15, 1919.

Application led November 27, 1918. Serial No. 264,341.

To all 'whom z't may concern:

Be it known that I, WILLIAM D. ARNoT, a citizen of the United States, residing at Bellevue, in the county of King and State of Washington, have invented certain new and useful Improvements in Combined Wrenches and Pliers, of which the following is a specification.

This invention relates to tools, and more particularly to combined wrenches and pliers.

The object of the invention is to provide a tool of this character constructed lwith parallel jaws capable of use either as a wrench or as a pai-r of pliers.

Another object is to so construct such a tool that the element carrying the movable jaw will be always housed and in which the pressure exerted in closing the jaws is 'directly below said element.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a side elevation showing one embodiment of this invention,

Fig. 2 is a similar view with'parts broken out and in section showing a slightly different form,

Fig. 3 is a detail bottom plan view of one of the jaws,

Fig. 4 `is a similar view of the other jaw, and

Fig. 5 is a detail side elevation with parts broken out and in sectionof a tool head embodying this invention in a slightly different form.

In the form shown in Fig. 1, an outwardly bowed handle 1 is shown carrying at its front end a fixed jaw 2 between which and said handle is a hollow head 3. Mounted -to move in said head 3 is a movable jaw 4 which is arranged parallel with jaw 2 and is carried by a threaded bolt or shaft 5, said bolt in this form of the invention being shown made integral with the jaw 4, but which need not necessarily be so made as will be hereinafter more fully explained.

This bolt 5 .is movable through an opening 6 in the hea`d 3 at the base of jaw 2 as is shown clearly in Fig. 2, the structure of Fig. 2 s)being identical with that of Fig. 1 in thlS particular, the only difference in these two figures being that the handles are differently formed.

A knurled nut 7 is carried by the bolt 5 and is rotatable to move jaw 4 toward and away from jaw 2 when it is desired to adjust these jaws for diiferent-sized Work to be grasped when the tool is used as a wrench. The handle 8 ofthe structure shown in Fig. 1 is bowed oppositely to the handle 1 and carries at its inner end a head 9 which is positioned withinthe head 3 and is fulcrumed at 10 carrying at its front end a pair of vertically spaced jaws 11 and 12 between y i which the nut 7 is designed to pass, as is shown in dotted lines in Fig. 1 and in full lines in Fig. 2, so that when the handles are compressed'toward each other, the jaws 2 and 4 will be closed in the same manner as a pair of pliers, the jaws moving in parallel relation to each other. A spring 11 is arranged between the handles 1 and 8 being secured at one end to one handle and bearing at its other end against the other handle on its inner face and exerting its tension to normally hold said handles in spaced relation and the jaws 2 and 4 open.

The structure shown in'Fig. 2 as above stated is exactly the same as that shown in Fig. 1, except that the handles 1a and 8a are differently curved, being bowed in the Same direction so that handle 8a with the head 9 carried thereby is substantially S-shaped and the spring 11b which is arranged between them is differently curved to conform to the shape of the handles; otherwise the structure is the same and operates in the same manner as that shown in Fig. 1.

In the form shown in Fig. 5, the handles are shown broken oli' and may be constructed like those in either of the above described figures. The head 3a of this tool is the same as that of the figures above described carry.

ing at its lower front end a lixed jaw 2, and a movable jaw 4a is mounted therein to move toward and away from jaw 2. This jaw 4a has threaded connection with the shaft 5a instead of being made integral therewith as in the forms above described. The bolt 5a has a knurled annular projection or ange 7a made integral with its lower end, and

projecting from the lower end of said bolt below said flange is a stem 13 having a head 14. This knurled flange 7a is movable in a chamber 15 in head 3a so that on the turning of said flange the bolt will be carried therewith and not be projected beyond the aw 2 as is the case in the structure shown in the other figures, it being understood that the turning of this flange will operate to move jaw 4 to adjust it toward or away from jaw 2.

The handle 8b of the tool shown in Fig. 5 carries at its front end a head 9a which is vcurved outwardly and provided at its terminal with an aperture 16 through which passes the stem 13 carried by boltli, this aperture being flared toward its inner end and having a seat 17 in its outer end to receive the head 14 of the stem 18. The spring 11b shown in this figure is the same as that shown in Fig. '2 and operates in the same manner.

In the use of this tool it will thus be seen that by compressing the handles carrying jaws 2 and 4n said jaws will move toward each other in parallel relation and operate as a pair of pliers to grip the article and if desired they may be positioned toward or away from each other for use as a wrench by adjusting the bolt 5IJL by means of the flange 7u;

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertain's; and while I have described the principle of operation ofthe invention together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a tool of the class described, a handle having a head at one end provided with a fixed jaw, a jaw movable in said head toward and away from said xed jaw, a threaded shaft carrying said movable jaw, rotary means carried by said shaft operable to adjust said movable jaw, and another handle pivoted to said head and having a connection with said shaft to operate the tool as a plier.

2. In a tool of the class described, a handle having a. head at one end with a fixed jaw extending longitudinally therefrom, a jaw movable in said head toward and away from said fixed jaw, a threaded shaft carrying said movable jaw, and another handle pivoted to said head and having a swiveled connection with said shaft.

3. In a tool of the class described, a handle having a head at one end with a fixed jaw extending longitudinally therefrom, a jaw movable in said head toward and away from said fixed jaw, a threaded shaft, a flange lfixed to said shaft for turning it, .sa-id movable -jaw having threaded connection with said shaft, another handle pivoted to said head and having a swiveled connection with said shaft.

4. In a tool of the class described, a handle having a head at one end with a fixed jaw extending longitudinally therefrom, a jaw movable in ,said head toward and away from said fixed jaw, a threaded shaft, a flange fixed to said shaft, said movable jaw having threaded connection with said shaft, a stem depending from said shaft, a head on the lower end of said stem, another handle pivoted to said head with its front end curved outwardly and provided at its terminal with an aperture through which said .stem passes, said aperture being flared toward its inner end to permit swivel con-` nection between said stem and handle.

5. In a tool of the class described, a handle having a. head at one end provided with a fixed jaw and a recess, a jaw movable in .said recess 'toward and away from said fixed jaw, said head having another recess communicating with the recess in which said movable jaw is mounted' and larger than said first-'mentioned recess, an element carried by said movable jaw and located in said larger recess whereby the free movement of said jaw is limited, and a handle pivoted to said head and having a connection with said movable jaw to operate the tool as a plier.

fIn testimony whereof I aflix my signature in 'presence of two witnesses.
