Description
UNITED STATES PATENT OEEICE.
GEORGE GRBEL, OF NEW ORLEANS, LOUISIANA.
IMPROVEMENT IN TAPS AND DIES.
Specification forming part of Letters Patent No. 81,162, dated August 18, 1868.
To all lwhom it may concern:
Be it known that I7 GEORGE GRBEL, of New Orleans, in the parish of Orleans and State of Louisiana, have invented new and Improved Screw-Outting Dies; and I do hereby declare that the following is a full, clear, and exact description thereof, which 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.
Figure l represents a sectional view of my improved screw-die. Fig. 2 is an inner face view of one of the cheeks of thel same. Fig. 3 is a similar view of the other cheek of the same. Fig. 4 is a plan or top view of the same.
Similar letters of reference indicate corresponding parts.
cheeks the second, fourth, sixth, eighth, &c.,
and many cutting-edges are produced by theprojecting ends of each portion of thread, and the device will therefore work with less friction, and will require less power than the full unbroken thread.
The same invention is applicable to male-die screws for making nuts, in which case, also, alternate sections of the cutting-thread are removed.
I claim- As my improvement of screw-cutting dies and taps, whose threads are divided transversely, so as to present two or more salient cutting-points, omitting every alternate thread, and arranging those that remain in alternation, so that the sections of cutting-thread following one another shall successively cut and give shape to opposite sides of the thread in the nut, or on the boltwhich is being threaded or tapped, substantially as described.l
GEORGE GRUBEL.
Witnesses:
F. A. LOEEER, GorrL. BRENNENs'rUHL.
