Letters Patent No. 99,027, 'dated January 18, 1870.

INPROVED DIE FOR FORMING- SHUTTLE-TIPS.

The Schedule referred to in these Letters Patent and making part 'offthe same.

To allfwliom it may conce-rn:

Be it known that I, ALsoN A. STONE, of Shirley, innt-he county of Middlesex, and State of Massachusets, have invented new and useful Improvements in Machine for Making Shuttle-Tips; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings', and to the letters of reference marked there- The nature of my invention consists in providing a die, to be operated in a drop or tilt-hammer, its form andcapacity being such, that metal shuttle-tips may be perfectly formed and finished, with a concave base, at one'operation.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construcltion and operation. Figure 1 represents a plan of my improved die.

Figures 2 and 3 represent a vert-ical section of the same.

Figure 4 represents a vertical sectionl of an unn- Y ished tip.

the top part of this baseb being formed convex.

When thus constructed, the die is placed in the drop or tilt-hannner, the cup parta being on top of the base b.

The unfinished tip, as shown in iig. 4 of the drawings, is then heat-ed, as required, to a cherry red, and placed in position in the-base b.

' The 'cup a is then brought in contact with the top .of the saine, by operating the drop or tilt-hammer,

which compresses the saine into the-desired shape, as shown in fig. 5 ofthe drawings, and also, bythe same operation, providing 'it with a concave base, e.

The common method of making shuttle-tips has been to forge and work the same in shape Aby hand, which leaves them in an unfinished shape, as.- shown in fig. 6 of the drawings; after which they would be finished, the concave base e and point of tip by being turned true and in shape ina lathe, which, by their peculiar form and shape, renders them extremely diiicult to be handled and finished, even at a slow rate; while, by my improved device, after the tip leaves the die, they being formed by compression, the only finish required is to polish the outside surface of the tip, as they are formed as true an perfect as the die itself, and, by thisprocess, can be compressed into shape as fast as they can be handled by the operator.

What I claim as myinvention, and desire to secure by Letters Patent, is-

The construction and combination of the dies a and b, for forming shuttle-tips, as described, said dies being ofthe form and capacity as described.
