IMPROVED DIE POR CUTTING THREADS ON TUBES.
@Ligt rgerte referer tn in ipse trttws patent intending part nf yits same.
To ALL' WHOM IT MAY' CQNCERN;
Be it known that I, WILILIAM T.COLE,oi` the city, county, and-State of New York, have invented a n'ew and improved Die for Cutting Threads on Tubing; and I do hereby declare that' the following is a full, clear, and exact description thereoffwhich' will enable others skilled in' the art to make and use the same, reference being had to the accompanying drawings, forming part of'this specification, in which- Figure 1 is a front view of my Iimproved die, and
Figure 2 is a vertical section of the same, taken onQthe line :e rv, Eg. l.
Similar letters of reference indicate corresponding parts.
This invention relates to a device whereby screw-threads are cut on ytubes and other cylindrical, solid, or hollow articles,and consists in making the die by which the screw-threads are cut, of two or more pieces, which are pivoted to a vertical suspended plate, and which are clamped together, so as to form a circular die while the Vthread is being cut, but which are thrown apart by meansoi` springs or weights as soon as the thread has been cut, thereby allowing the easy removal of the tube, while heretofore, when full dies were used, the tube had vto be turned back out of the die. A great saving of time and laboris thus accomplished by the` use of this invention, and the cutting of threads on tubes, &c. is thus considerably simplified and cheapened; the apparatus itself being of the most simple construction, and cheaply made.
A represents a plate, which 'is made of cast or wrought iron., and which is suspended from a'stationarly pin which passes through a hole, a, in the upper part o" the plate. To the lower part of the plate A. are pivoted,
by means of pins b b, 'two steel arms B B, in each of which a semicircular recess is formed, in which the teeth' l or edges for cutting the thread on a tube are arranged', as is clearlyshown in the drawings. On top the two plates B B meet or touch 'each other, and when they are clamped together by a recessed lever, C, which is held down by 'a spring, D, and pivoted to the'plate A by a pin, c, the circular die is formed by the two semicircular recesses, as shown in fig. 1. Below the `circular' opening E, which is thus formed btween the plates B B, is formed a channel, F, between the inner edges of the die-plates B, for the purpose of conducting ofi` the borings or shavings, which would otherwise clog the dies. 4A semicircular or other spring, G, of whichone end is secured to either plate B, asA shown, serves to throw the latter apart as soon as the clutch C is raised, y thereby bringing` the parts into the position which is indicated by red lines nhg. l. The tube on which a thread was out while the dies were lockedl together can now 'be withdrawn with case and facility. By a lever, H, which is pivoted to one of the plates B, and which is connected with the end of an arm, I, which is pivoted to the other plate B, the latter can be instantly locked. It is only necessary to raise the ends of the lever whereby the die will be formed or closed, and then the spring Dwill instantly force the' clutch C upon the upper ends ofthe plates B, whereby the same are locked. d d are stop-pins, which prevent the diesfrom being drawn too furV apart, whereby the spring G is protected from being overstrained. The spring I) is protected in la. similar manner by` a stop, e, which prevents the lever C from being elevated too high. i
Having thus described my invention, what I claim as new, and desire to securehy Letters Patent, is
1. The combination of the base-plate A, pivoted die-plate B, spring C, .lever H, and link I, arranged substan- 4tially as described. l l
l i 2. The combination" with the above of 'the clutch C, appliedv and operating in the manner and for the purpose Bpecied. i
WILLIAM4 T. COLE.
