Description

` I'. TRANSUE. Dies for Threshing-Maohine Spikes.
No. 221,372. Patented Nov. 4,1879.
Foy. l
UNITED STATES PATENT OEEIGE.
FRANK TRANSUE, OF ALLIANCE, OHIO.
IMPROVEMENT IN DIES FOR THRASHING-NIACHINE ASPIKES.
Specification forming part of Letters Patent No. 22l,372, dated November 4, 1879 application filed February 25, 1879.
To all whom t may concern:
Be it known that I, FRANK TRANsUE, of Alliance, in the county of Stark and State of Ohio, have invented a new and useful Improve ment in Dies for Making Thrashing-Machine Spikes and other forged articles, which im provement is fully set forth in the following specification.
In reference to the accompanying drawings, Figure lis a perspective view of the invention, showing the dies A, B, O, and D brought together as they are, While forming a spike.
Fig. 2 is a view of the right-hand die G, which forms the convex edge of the spike. Fig. 3 is a view of the left-hand die D, which forms the concave edge of the spike. Fig. 4 is a view of the die B, which is exactly like the upper die, A.
A and B are dies having recesses, as shown at a, by which the thick portion of the spike is formed. C is a die, having a recess, as shown at c,by which the convex edge and a portion of the stem of a spike is formed. D is a die, having a recess, as shown at c. rllhe dotted lines at l represent the spike inclosed in the dies A, B, C, and D, when completed by the use of said dies. c is a recess in the die D, by which the concave edge of a thrashingmachine spike is formed. c is a recess in the die C, by which the convex edge of a thrashing-machine spike is formed. a represents a recess, which is alike in both the upper and lower dies, which is used for forming the thick portion of the sides of a thrashing-machine spike.
The operation of my invention may be de-V scribed as follows: The said die B is firmly fixed in the base or anvil of a drop-hammer or its equivalent. The die A is attached to the drop of said machine. As the said die A starts in its downwardmovement, by the use of leve-rs or their equivalents, the die G and D are moved in the position in which they are seen in Fig. 1, where they remain until the said die A has completed its stroke. As the said die A rises, after having completed its stroke, the dies G and D move apart and so remain until the die A again drops, when, as the said die again starts downward, the said dies O and D are again brought together, and so remain until the said die A has again conipleted its stroke.
What Iclaini is- The combination of the dies A, B, O, and D, shaped as described, and for the purpose of forming thrashing-machine spikes.
