NITED STATES JAMES M. DODGE, OF INDIANAPOLIS, INDIANA.
SCREW-CUTTING D'IE.
SPECIFICATION forming part of Letters Patent No. 296,393, dated April 8, 1884.
Application filed November 22, 1883. (No model.)
To (123 whom, it may concern:
Be it known that I, Janus M. DODGE, a resident of Indianapolis, Marion county, Indiana, have made certain new and useful Improvements inScrew-Cutting Dies, a description of which is set forth in the following specification, reference being made to the accompanying drawings, in the several figures of which like letters indicate like parts.
My invention relates to devices for cutting threads upon metal "pipes, and is intended to provide dies which are readily adjustable to different sizes of pipes without the interchange of separate parts, and will be readily understood from the following description.
In the drawings, Figure 1 represents a side view of my device. Fig. 2 is a cross-section of a globular die-holder, and Fig. 3 is a perspective view of one having a cubical form.
In detail, S is the stock, which is made in two parts secured by clamp-screws c s on either side. The handles are threaded to screw into sockets at each end of the stock, and the ends of the handles work against bearing-plates b p, which prevent them from entering any of the openings in the die, and
by screwing up these handles the die itself is tightly clamped when placed in the stock. The die-holder G in globular form or O in cubical form are only modifications of the same device, and either may be used, the stock being shaped to correspond with the die-holder used. Both are made hollow with openings of the same diameter on opposite sides, the one d having the thread-cutting die inserted, and the opposite one, 9, being a guidehole in which the end of the pipe is inserted for feeding it up to the die. The holes are made of different sizes, to accommodate different sizes of pipe.
In Fig. l, 1; shows the pipe in the die.
The opening intended to be used is placed opposite the opening in the stock, and the dieholder is then firmly clamped by screwing up the handles at either end. Other forms of stock could be used with the dieholder. The one shown is simple and convenient; but I do not limit myself to the form shown either of the stock or die, as these could be varied at the pleasure of the mechanic without departing from the principle of my invention.
I am aware that screw-plates have been made having die-plates for cutting the thread upon one side and guideholes in the plate opposite, the whole forming a rectangular box, and do not broadly claim any such device. The difficulty, however, with devices of this classsuch as Deans,patented May 19, 187 4- is that the working-balance is only main tained when the central die is being used,and there is no arrangement by which the other dies, which are at the ends, may be brought to the center of the stock for use; and when the end dies are used the tool is out of balance, whereas in my multiple die, which is adjustable in the stock, any sized opening may be brought directly to the center for use, thus giving it a decided advantage over other forms of screw-plates.
What I claim, and desire to secure by Letters Patent, is the following, viz:
1. A die-stock adapted to receive and hold a movable block containing three or more sets of dies, with their respective guides so arranged that the axis of each die and its guide may, at will, be placed and held at right angles with the axis of the handles and coincident, or nearly so, with the longitudinal center of the tool when complete, preserving its working-balance, substantially as described.
2. The movable multiple faced die and guide herein described, the opening on one side adapted to receive and guide the pipe, the opposite face provided with a die for cutting a thread upon the pipe, in combination with any suitable die-stock for receiving and clamping the same, substantially as described.
In witness whereof I have hereunto set my hand this 14th day of November, 1888.
JAMES M. DODGE.
