Abstract

A flexible conduit clamp that can be hooked onto the rear rungs of a step ladder for use in clamping fast section of flexible conduit. Two rectangular right-angle sections act as the vise jaws to clamp about the pipe by means of an attached locking device and the right-angle jaws hold the pipe fast while operations are performed upon the pipe.

[56] References Cited UNITED STATES PATENTS fmmed the 2,105,954 l/l938 Rippe 269/321 N 1 Claim, 2 Drawing Figures PORTABLE PIPE CLAMP SUMMARY OF THE INVENTION This invention relates to a portable vise used to hold a pipe, with said vise being attachable to the rungs of a ladder.

The prime advantage of this invention lies in its portable nature.

A further advantage of this invention is that it can clamp pipes of varying diameters.

The invention comprises two jaws of right-angle shaped metal mounted such that a section of pipe can be plased between the two pieces of right-angle jaws, with one jaw piece rotatably mounted to the device so that the jaws can be locked about the pipe. The jaw pieces are mounted to two parallel and separate members to which hooks are attached, such that the entire device can be hooked onto the rung of a ladder, with the axis of a clamped pipe parallel to the rungs of the attached ladder.

BRIEF DESCRIPTION OF THE DRAWINGS The objects and features of the invention may be understood with reference to the following detailed description of an illustrative embodiment of the invention, taken together with the accompanying drawings in which:

FIG. I is a perspective view of the portable pipe clamp attached to a ladder; and

FIG. 2 is a side view of the clamping mechanism.

DESCRIPTION OF THE PREFERRED EMBODIMENT Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIG. 1 illustrates the portable pipe clamp which consists of the clamp mechanism l2 fastened to support members 16. Support members 16 are joined together by cross member 18 and terminate at their upper ends at their hooks 14. A hook arm 20 fits about the back feet support member 16 and is of a size to fasten about a ladder rung 30. Clamp mechanism 12 is fastened at each end to a support member 16 and the clamp mechanism runs parallel to the cross member 18 and to the rungs 30 and 28 of a ladder to which the device is secured.

The clamp mechanism 12 consists of two right-angle pieces of material 22 and 24 which are fastened in rotatable relation to each other. Angle member 22 is fixed to both support member 16, with angle member 24 rotatably fastened to a pin which is fixed to one support member 16 to permit angle member 24 to rotate in the vertical plane relative to angle member 22. A pipe section of flexible conduit or section oftubing may be placed between the open sections of angle members 22 and 24 so as to be gripped by the two angle members when they are brought together in a secure fashion. A handle member 36 is rotatably fastened by a pin 46 fitted into angle member 22 so that the handle may rotate in the vertical plane and a chain link 38 is rotatably fastened to handle member 36 of a size to fit into a book 34 fastened to the exterior surface of angle member 24. When the chain link is fitted about the hook and the handle member 36 rotated about pin 46, it serves to tighten the two angle members 22 and 24 together about a pipe 42 which may be clamped in between the two angle members. Fixed cross member 22 is formed with a U-shaped undercut 42 to permit a saw blade deployed in cutting a length of pipe 42 gripped by the cross members 22 and 24 to cut the gripped pipe without cutting into the fixed cross member 22.

Since obvious changes may be made in the specific embodiment of the invention described herein, such modifications being within the spirit and scope of the invention claimed, it is indicated that all matter contained herein is intended as illustrative and not as limiting in scope.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent of the United States is:

l. A device for clamping of a flexible conduit, pipe or tube, which device may be fitted about the rungs of a ladder, with said device hooking over the horizontal rungs of a ladder installed in the vertical position,

said device including two longitudinal support members joined by a cross member perpendicular to the two support members with the upper end, in the installed position of each support member, terminating in an open hook of a size to fit about a ladder rung and with each support member being fitted with an opened hook member at its rear of a size to fit about a second rung of a ladder to which the device is attached, together with a clamping device for clamping a pipe which is fixed to the two support members so as to lie generally parallel to a rung of an attached ladder, with the clamping device consisting of two opened angled members rotatably joined to each other. in which one of the clamp members is fixed to both support arms of the device with the other clamp member being fitted in rotatable relation to the fixed clamp member, with the rotatable clamp member being of shorter length than the fixed clamp member and with an undercut section of the fixed clamp member located adjacent to the end of the rotatable clamp member so that a pipe secured by both clamp members may be cut by a saw without the saw engaging the fixed clamp member.

Claims (1)

1. A device for clamping of a flexible conduit, pipe or tube, which device may be fitted about the rungs of a ladder, with said device hooking over the horizontal rungs of a ladder installed in the vertical position, said device including two longitudinal support members joined by a cross member perpendicular to the two support members with the upper end, in the installed position of each support member, terminating in an open hook of a size to fit about a ladder rung and with each support member being fitted with an opened hook member at its rear of a size to fit about a second rung of a ladder to which the device is attached, together with a clamping device for clamping a pipe which is fixed to the two support members so as to lie generally parallel to a rung of an attached ladder, with the clamping device consisting of two opened angled members rotatably joined to each other, in which one of the clamp members is fixed to both support arms of the device with the other clamp member being fitted in rotatable relation to the fixed clamp member, with the rotatable clamp member being of shorter length than the fixed clamp member and with an undercut section of the fixed clamp member located adjacent to the end of the rotatable clamp member so that a pipe secured by both clamp members may be cut by a saw without the saw engaging the fixed clamp member.
