FRANCIS S. WHITE, 0F PHILADELPHIA, PENNSYLVANIA.
METHOD OF MAKING- STAMP-SHOES.
Application filed March 19, 1915.
To all whom it may concern:
Be it known that I, FRANCIS S. WHITE, a citizen of the United Statesgresiding at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Methods of Making Stamp-Shoes, of which the following is a full, clear, and exact description,
reference being had to the accompanying.
drawings, which form a part of this specification.
The object of my invention is the economical production of stamp shoes of fine quality.
My process may be carried out in different ways, but I prefer to carry it out in the manner and with the apparatus illustrated in the drawings, in which Figure 1 is a side view, and Fig.2 a crosssection of an ordinary ingot. Fig. 3 is a side view showing the shape to which a section of the ingot is forged. Fig. 4 is a side view of the finished product. Fig. 5 is a vertical section of the die employed in the final operation. Fig. 6 is a vertical longitudinal section, and Fig. 7 a cross section (on line 77 of Fig. 6), of the forging die, the ingot section being shown in its original condition; Fig. 8 being a view similar to Fig. 7, but showing the article shaped in conformity with Fig. 3.
Initially, I take an ingot a and cut the same into sections of equal mass on the lines .12, An ingot section b is then placed between die members a and (Z (see Figs. 6 and 7). These die members are provided at one end with inwardly extending flanges 6 forming an abutment to prevent flow of the metal in one direction. The die members from their flanged or closed ends have parallel walls, while toward their opposite ends the walls converge as shown in Fig. 6. The walls of the die are cut away at f to permit of the entrance of a tool 9 whereby the piece may be turned.
In operation, the upper die member is Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

alternately lifted and depressed, the piece being turned after each action, thereby reducing its cross section and causing the metal thereof to flow toward the narrow mouth of the die. The piece is turned from time to time. At the conclusion of the forging operation, the piece is shaped to conform to the forging die, as shown at is, Fig. 3. It is then placed upon the lower die member h of Fig. 5, which, in conjunction with upper die member 2' and plunger 7' shapes the piece to its ultimate form, as shown at m, Fig. 4. This operation, which is an upsetting one, increases the diameter, and shortens the length, of both the body and the neck of the piece, besides flattening the shoulder between the body and neck.
Having now fully described my invention, what I claim and desire to protect by Letters Patent is:
1. The process of making stamp shoes, which consists in casting the piece, applying a forging pressure thereto in a radial direction while causing the metal at one end to flow longitudinally to form a neck of smaller diameter, and then compressing the same longitudinally and squaring the shoulder between head and neck.
2. The process of making stamp shoes, which consists in casting the piece, applying a forging pressure in a radial direction thereto while limiting the longitudinal flow of the metal in one direction and causing it to flow longitudinally in the other direction toform a contracted neck joined to the body by a sloping wall, and then compressing the same longitudinally and squaring the shoulder between head and neck.
In testimony of which invention, I have hereunto set my hand, at Philadelphia, on this 12th day of March, 1915.
