JAMES J. COYNE, F CAMBRIDGE, MIASSACHUSETTS, ASSIGNOR OF ONE-HALF TO JOHN F. MURPHY, OF CAMBRIDGE, MASSACHUSETTS.
DIE HOLDER.
To all whom it may concern:
Be it known that I, JAMES J. Cornn, a citizen of the United States, residing at Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain useful Improvements in Die Holders, of which the following is a full, clear, and exact description. 1
This invention relates to thread cutting apparatus and is more particularly designed for use in close quarters where it would be practically impossible to employ the ordinary thread cutters which are operated by means of relatively long laterally extending handles.
An object of the invention. resides in the provision of an inexpensive yet durable holder for the thread-cutting die combined with means swivelled thereto for the purpose of aaplying longitudinal. pressure during the threading operation.
Other objects and advantages of the invention will be apparent from the following detailed description taken in connection with he accompanying drawings, in which,
Figure 1 is a perspective view of my de vice in use.
Figure is a perspective view thereof with the die and bushing detached, and
Figure 3 is a fragmentary side elevation with parts shownin section.
In the drawings thus briefly described the numeral 1 indicates a rectangular metal. receptacle which may be formed in any desired manner. This receptacle is adapted to re ceive die blocks of various sizes as indicated by the numeral 2, and in order that the same may be securely held in place I provide a bushing 3 formed with the threaded recesses 4: in opposed. sides thereof. 'llhe bushing is of a size to be received within. the receptacle 1 and is pressed against the die block 2 while the set screws 5 carried by the side walls of the receptacle are threaded into the apertures 4-. It will thus be seen that the die block is securely locked in place for use.
Attached to two of the side Walls of the receptacle 1 by electric Welding or otherwise, is a U-shaped member 6, and to the base of this U-shaped member is rigidly secured the shank or projection 7. The thread cutting operation is performed, of course, by rotating the die, and to this end the projection 7 is provided with one or more flat faces 8 suitable for gripping by the ratchet tool 9. It is often desirable to put a rather long thread on a pipe and in order that this may be accomplished the base of the receptacle 1 is aperture as indicated by numeral 10 to allow the threaded end of the pipe to pass through.
In starting all threading operations it is necessary that the die receive longitudinal pressure in addition to the force required in turning the same about the pi as or rodbeing threaded. I have accorc ingly swivelled to the end of projection 7 a saddle 11. It will thus be apparent that pressure may be applied through the saddle to the (lie 2 without in any way interfering with the usual rotation of the latter.
From the foregoing description it will be apparent that I have devised an extremely simple and inexpensive die holder; that the same is adapted to use in confined spaces: and that the size of the die may be varied as required. I
In accordance with the patent statutes I have described what I now believe to be the best embodiment of the invention, but I do not wish to be understood thereby as limiting myself or the scope of the invention, as many changes and modifications may be made without departing from the spirit of the invention; all suchl aim to include in the scope oi the appended claim.
hat I claim as new and desire to secure by Letters Patent is:
A die holder including a receptacle free from lateral projections and adapted to receive a die a busl'iing adapted to be seated. within said receptacle against the die, set screws located in the side walls of said receptacle for engaging the edges of the bush-
