.Z-ZECIFIGATEQN forming part of Letters Patent No. 321,967, dated July 14, 1885.
Application filed January 19, 1885.
To all whom it may concern:
Be it known that I, FRANK W. HASTINGS, a citizen of the United States, residing at NVallingford, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Punches for Making Dies for Forming the Heads of Angers, of which the following is a specification, reference being bad therein to the accompanying drawings, in which Figure l is a plan view of the under side of the punch, and Fig. 2 is a perspective View of the same. Fig. 3 is a plan view of the die or impression made by the punch. Fig. 4 is a view of the pintle which forms a part of the die. Y
My invention relates to a punch for making dies for forming the heads of angers and bits. Heretofore these dies have been made by cutting-tools in the hands of a die-sinker.
The object of my invention is to reduce the cost of these (lies, and to make them more nearly alike.
The letters on the several parts of the punch are used to designate the corresponding parts or depressions in the die.
Toenable others to make and use my improved punch, I will give a detailed description of the same.
A cubical block of steel, A, has its upper end formed to be held in an ordinary drop. Its lower end is planed or cut away, leaving the flat or plane surface B and a projecting partnvhich is formed into a half turn or twist, a, of an auger, one half, I), of a conical point, and the part c. The part d is made thick to form a cutting-lip. The part 0 does not correspond with the twist of an anger, but is made thicker, so as to make a deeper impression in the die,whereby the twist will not come against the die when the auger is inserted to form the (No model.)
manner of using it is as follows: A block of steel is slowly and evenly heated to as high a temperature as it will bear without burning. It is then placed and securely fastened in an ordinary drop, and the punch let fall upon it at intervals. Between the intervals water may be thrown into the impression made by the punoh,to remove the scale and securea smooth impression. Preferably I make four or five blows with the punch and a better impression is thus made than when only one or two are made. The die is then planed off and the ordinary and wellknown pint-1e E, Fig. 4, is inserted in the die in the ordinary way to com plete it, the place of insertion beingindicated by dots in Figure 3.
Having described my improved punch, what I claim, and desire to secure by Letters Patent, 1s
The punch herein described, having its lower end or side cut away to form the plane surface B, one-half, a, of a turn or twist of an anger or bit, one-half, b, of a conical point, and the part c, the half turn or twist increasing in thickness from its outer edge and having the thick part d to form a cutting-lip, substantially as shown and described.
In testimony whereof I affix my signature in presence of two witnesses.
FRANK IV. HASTINGS.
