. v SLIDABLE SIDE JAW WRENCHES I Filed April 8, 1957 IN V EN TOR. W

A r roRivsr United States Patent SLIDABLE SIDE JAW WRENCHES Charles H. Peltcher, San Diego, Calif. Application April 8, 1957, Serial No. 651,295 2 Claims. (Cl. 81-165) My invention relates to slidable side jaw wrenches as adapted for the accomplishment of clamping contact of the jaws of the wrench with the object to be turned wherever its location.

Its primary object is to render such type of wrench more effective than heretofore in confined quarters where difficulty is encountered in applying the jaws of the struction, and combinations and arrangements of parts and elements illustrated in the drawing and as hereinafter more specifically described and claimed.

The present invention is an improvement upon the invention heretofore made by me as set forth in the application resulting in U. S. Letters Patent for Handle Attachment for Wrench Head, No. 2,788,691, issued to me April 16, 1957.

Attention is hereby directed to the accompanying drawing illustrating a preferred form of my invention in which similar numerals or designation refer to similar parts throughout the several views, and in which,

Figure 1 is a side elevation of the major portion of said form of my slidable side jaw wrench, showing the integral basic structure, with the movable jaw member removed therefrom;

Fig. 2 is an end elevation of said basic portion of my device as shown in Fig. 1, looking in the direction indicated by the arrows 22;

Fig. 3 is an end elevation of the opposite end of the structure shown in Fig. 1, looking in the direction indicated by the arrows 33;

Fig. 4 is a side elevation of the assembly of parts constituting my complete slidable side jaw wrench including the movable jaw member; and

Fig. 5 is a view partly in section of a conventional water meter box, illustrating the combined device shown in Fig. 4, introduced thereon, the jaws of said wrench being shown in operative contact with one of the meter unions, and positioned to turn the same.

Referring to the drawing, the jaw wrench there shown is composed of two parts, that is, the basic structure 6 carrying the jaw 7, and the movable jaw member 8, carrying the jaw 9; each of said jaws being serrated and preferably of steel.

The basic structure is preferably of cast iron, but may be of any suitable material, and is preferably formed with a head 10 having depressed therein and opening out- "ice wardly and upwardly therefrom the sockets 1]., 12 and 13; the socket 12 extending vertically and the sockets 11 and 13 extending upwardly substantially at an angle of forty-five degrees in relation to the socket 12. Each of said sockets is shaped to receive and readily to seat the lever rod 14, the operation of which is shortly to be described.

Extending downwardly from the head 10 of the said basic structure 6 and integral therewith is the neck 15 merging into the foot or shoe-shaped portion 16, said neck having extending therethrough the passageway 17, shaped slidably to receive the threaded shank 18 of the movable jaw member 8. Firmly secured to the heel of said shoe-shaped portion 16 is the jaw 7, positioned to engage the jaw 9 upon sliding movement of shank 18, and formed in the upper part of the toe of said portion 16 is the recess 20 shaped to receive and located to clear for ready manipulation the nut 21 of said shank 18. Preferably, to lighten said shoe-shaped portion 16, I form the same at the sides thereof with the longitudinally extending depressed grooves 19.

By making all parts of said basic structure integral therewith, and of the form and in the co-operative association hereinbefore set forth, I have greatly simplified and improved the construction of my aforesaid patented handle attachment, and have produced a structure of great strength and durability better adapted to sustain the stress and strain imposed upon it; thereby producing the sought for result in a more facile, economical and efiicient way than has heretofore been accomplished.

In operating said combined wrench and attachment construction in a confined space such as the water-meter box 23 shown in Fig. 5, I first adjust the jaws 7 and 9 so as to fit the meter-union there shown and thereupon, I lower the combined device into the said box and cause the said jaws to engage the said union. Then, by introducing the turning lever rod 14 successively or as may be required into the

sockets

11, 12 and 13, to secure the greatest leverage, I effect such turning as may be necessary to release from or to secure the water-meter within said box.

My invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment as above set forth is, therefore, to be considered in all respects as illustrative and not restrictive, the scope of my invention being indicated by the appended claims rather than by the foregoing description, and all changes which may come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

What I claim and desire to secure by Letters Patent is:

1. In a jaw wrench assembly, the combination of an integral basic structure, comprising a head having downwardly disposed sockets therein, a neck downwardly ex.- tending from said head, and a foot connected with said neck, said neck having a passageway extending therethrough in the direction of the length of said foot, the heel of said foot having a jaw secured thereto, and the toe of said foot having a recess in the top thereof laterally extending across the same; a movable jaw member comprising a threaded shank shaped and positioned to make slidable engagement with said passageway, a jaw depending from and secured to said member and located to make engaging contact with the jaw of said heel, and an adjusting nut engaging with said shank and positioned to turn thereon and within the recess of said foot; and a lever adapted to engage with the sockets of said head and to turn the same in the direction of the length of said foot.

2. In a jaw wrench assembly, the combination of an integral basic structure, comprising a head having downwardly extending straight-away and angularly disposed Patented Mar. 4, 1958' 3 sockets therein,- a neck downwardly extending from said head, and a foot connected with said neck,said neck having a passageway extending therethrough in the direction of the length of said foot, the heel of said foothaving a serrated jaw secured thereto, and the toe of said foot having longitudinally extending grooves in the sides and a recess in the top thereof laterally extending across the same; a movable jaw member comprising a threaded shank shaped and positioned to make slidable engagement with said passageway, a serrated jaw depending from and secured to one end of said member and located to make engaging contact with the jaw of said heel, and an adjusting nut engaging with said shank and positioned to turn thereon and within the recess of said foot; and a lever adapted to engage with the sockets of said head 15 4 and to turn the same in the direction of the length of said foot.
