UNITED. STATES PATENT OFFICE.
I CLARENCE V. GREENAMYER, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR TO THE VERNER WRENCH CAR-MOVER AND POWER MANUFACTURING COMPANY, OF SAME PLACE.
BENCH-CLAMP FOR PIPE TONGS AND WRENCHES.
SPECIFICATION forming part of Letters Patent No. 444,778, dated January 13, 1891.
Application filed September 9, I890. Serial No. 364,475. (No model.)
To aZZ whom it may concern:
Be it known that I, CLARENCE V. GREEN- AMYER, a citizen of the United States, residing in the city and county of San Francisco,
State of California, have in vented certain new and useful Improvements in Bench- Clamps for Pipe Tongs and renches, of which the following is a specification.
My invention has for its object to provide a device for fixing upon a work-bench or other stationary support a pipewrench, a pipe-tongs, or an implement of that class to grasp and hold a piece of pipe or tubing while work of some kind is being done, such as cutting the end, running a screw-thread,
or fixing a screw-joint or coupling. In combination or connection with a wrench or tongs the device furnishes a handy and efficient substitute for a vise, and enables tools of that character which have gripping-jaws on the ends of pivoted handles to be used in many cases without a helper or additional workman, so that one man can perform many operations without assistance.
The nature of my invention and the manner in which I proceed to produce, construct, and carry out the same will be understood from the following description, the drawings that form part of this specification being referred to by letters.
Figure 1 represents the manner in which a pipe-tongs with two levers or handles is fixed and held in the clamp, and shows the clamp in front elevation. Fig. 2 is a view taken 55 from the left-hand side of Fig. 1. Fig. 3 shows a pipe-wrench of the single-lever kind combined with the clamp.
A bar A of channel iron or a bar with a deep groove along the top and a flat bottom forms the bed of the clamp. The channel or groove is about equal in width to the thickness of the iron of which the members of the tongs or wrenches are made, so that when the jaws and the end portion of the handles are set on the bed the standing sides assist in supporting the tool. A hole a is made through the bottom of the channel at a point I about midway between the two ends for an upright rod B, the top or upper end of which has a loop or stirrup B while the lower end portion is screw-threaded and is fitted with a hand-nut C. The rod is passed through the hole in the bed to bring the threaded portion below it. The bar is set on a bed-timber or mounted on a bench where suitable space beneath is afforded to work the hand-nut, and the handle or lever portion of the tongs or wrench is passed through the loop on the upper end of the rod when the tool is set in the clamp, the position of the parts being such that the jaws or gripping edges of the tool are pressed and held firmly against the piece inserted between them as the screw-rod is drawn down by the hand-nut.
This clamp is adapted for use with many varieties of pipe-tongs and like tools which are used to grip and hold pipe-tubing, pipejoints, and other cylindrical pieces. In connection with such a tool it furnishes a ready means of holding a piece of work while operations of different kinds are being carried on. It will be found an efficient substitute for a vise, while it also enables the tool to be used in its ordinary capacity, when desired.
Having thus fully described my invention what I claim, and desire to secure by Letters Patent, is-
1. The herein-described clamp or device for holding pipe tongs and wrenches, consisting of the grooved or channeled bar, the rod hav- 8o ing a loop or stirrup on the end above the bar, its lower end screw-threaded, and a handnut on the screw-thread.
2. The combination, with the channel-iron bed adapted to take a pipe wrench or tongs, of the loop or stirrup having a screw-threaded end portion and a hand-nut as a means of drawing down and holding the stirrup.
In testimony that I claim the foregoing I have hereunto set my hand and seal.
CLARENCE V. GREENAMYER. [L 8.]
