PIPE WRENCH WITH STEA-DY REST Filed Sept. 27, 1965 INVENTOR. W34? .0. HHG'EE/VZM United States Patent 3,320,836 PIPE WRENCH WITH STEADY REST Wray D. Hagerinan, P.O. Box 56, Rocky Point, N.Y. 11778 Filled Sept. 27, 1965, Ser. No. 490,464 1 Claim. (Cl. 81-180) My invention is directed toward pipe wrenches with supporting structures.

It is an object of my invention to provide a new and improved pipe wrench and supporting structure which can be used as a holding wrench in place of a pipe vise by being placed upon a floor or ground surface with open jaws upward, the supporting structure sup orting the wrench in such manner as to prevent same from rolling over or being shifted in position during use as a vise.

Another object is to provide a new and improved supporting structure of the character indicated which can be manufactured easily and inexpensively.

All of the foregoing and still further objects and ad vantages of my invention will now be explained with reference both to this specification and to the accompanying drawings wherein:

FIGURE 1 is a side view of one form of my invention;

FIGURE 2 is a bottom view thereof;

FIGURE 3 is a cross-sectional view through 3-3 in FIGURE 1;

FIGURE 4 is an end view of the form shown in FIG- URE 1;

FIGURE 5 is a cut-away detail view of another form of my invention;

FIGURE 6 is a bottom view of the invention shown in FIGURE 5 FIGURE 7 is a side view of the invention shown in FIGURE 5; and

FIGURE 8 is a perspective view of still another form of my invention.

Referring now to FIGURES 1-4, there is shown a pipe wrench having an elongated handle 10 having a jaw 12 at one end and a sleeve or bridal 14 pivotally secured at 16 to the handle adjacent the jaw 12. An L shaped movalble jaw 18 extends through a bore in bridal 14 parallel to the handle and has peripheral threads 20 engaged by the inner threads of a cylinder 22 mounted in a slot in bridal 14, whereby rotation of cylinder moves jaw 18 toward or away from jaw 12. Bridal 14 has a rear flat rectangular surface 24 remotely spaced from handle 10. A flat rectangular plate 26 is provided with a central hole 28 through which a pin 30 extends, this pin projecting perpendicularly inward to surface 24 whereby plate 26 can be rotated about pin 30, plate 26 being adjacent and parallel to surface 24. The surface of plate 26 adjacent surface 24 carries a circular finger 32 spaced apart from pin 30 and engageable with the disengageable from a recess 34 on surface 24. When recess 34 engages finger 32, the plate 26 is in registration with surface 24. When the plate 26 is rotated to a position 90 away from the position of registraiton, and the wrench is placed with the jaws pointing upward with plate 26 resting on a suitable surface such as the ground, the structural arrangement permits the form shown in FIGURES 14 to be used as a pipe wrench vise in the manner previously described.

Referring now to FIGURE 8, plate 26 can be replaced by a cradle having a flat surface plate 40 resting on the ground and two parallel U shaped plates 42 extending upward therefrom in planes perpendicularly to the direction of extension of the handle, whereby the bridal can rest within these two plates to permit use as a pipe wrench vise.

Referring now to FIGURES 5-7, plate 26 of FIGURE 1 can be replaced by a cradle having a flat surface plate 50 resting on the ground and two parallel U shaped plates 52 extending upward therefrom in planes parallel to the direction of extension of the handle whereby the bridal can rest between these two plates. A second rectangular plate 54 is pivotally secured by a transverse pin or screw 56 to the underside of plate '50 in the same manner as plate 26 is secured to surface 24 in FIGURE 1, and functions in the same manner as late 26 in FIGURE 1.

The novel features and the operation of this device will be apparent from the foregoing description. While the device has been shown and the structure described in detail, it is obvious that this is not to be considered limited to the exact form disclosed, and that changes may be made therein within the scope and the spirit of the invention.

Having thus set forth and disclosed the nature of this invention, what is claimed is:

A pipe wrench comprising an elongated handle having a jaw at one end, a sleeve pivotally secured to said handle adjacent the jaw thereof, said sleeve having a bore extending parallel to the direction of elongation of said handle and a slot having therein a rotatable cylinder having an internal threaded bore parallel to the sleeve, said sleeve having a rectangular fiat rear surface spaced apart from said handle, an L shaped jaw having a peripheral thread and extending through the sleeve and cylinder bores with the cylinder bore engaging said peripheral thread, a supporting cradle having a flat elongated bottom plate extending in another direction perpendicular to said direction of elongation and two oppositely disposed parallel vertical U-shaped plates extending in said other direction whereby said sleeve is supported detacha bly in said vertical plates and spans said horizontal bottom plate, an additional flat plate parallel to the bottom plate and disposed therebelow, and a transverse elongated member extending between the bottom. plate and said another plate whereby said another plate can be rotated about said member in a horizontal plate.
