,WIRE-DRAWING DEVICE.

SPECIFICATION forming part of Letters Patent No. 354,991, dated December 28, 1886.

Application filed March 22, 1886. Serial No. 196,093. (No model.)

To all whom it may concern:

Be it known that I, THOMAS P. STRAUP, a citizen of the United States, residing at South Easton, in the county of Northampton, State of Pennsylvania, have invented certain new and useful Improvements in VVire-Drawing Devices, of which the following is a specificaeral views.

wireis being drawn.

for the die.

The letter A indicates the die-holder, preferably constructed of iron. This die-holder is provided with a series of openings tapering from a large opening in the top B to asinaller opening on the lower side, (marked 13'.) Said die holder is also provided with a small recess, O, on its upper side communicaing with the opening B.

D represents my improved die with a funnel-shaped opening therein. (Indicated by the letter D.) The sides of the die taper from the top downward, so as to fit snugly in the die-opening, said opening constituting a seat The top and bottom parts of the die are parallel, and are in a line with the top and bottom, respectively, of the die-holder.

E represents a lug on the upper side of the die. This lug is adapted to fit into the recess 0 in the die-holder, whereby the die is prevented from turning in the die-holder while Thelug Eis also for the purpose of preventing the turning of the die in the die-holder A when the die isheing reamed.

The operation of the device is as follows: The wire is passed into the top of the funnelshaped opening and then drawn through the small bottom opening, (1, until it is reduced to the desired size in the usual manner.

The old means for drawing wire consisted in an iron block with ten to sixteen holes in it. v The iron rod, being heated, was drawn through repeatedly until reduced to the proper size. These holes in the beginning are of the same size,but becomerapidly enlarged, and are then used for larger size of wire until they become too large. A good die with ten holes will stand the use of one man about a day. The openings are then rereamed to nest a larger size. After being rereamed five to eight times it becomes worthless, except for old iron,and, as it must be of best quality, thewaste is very great.

My dies last aboutthe same time as the old form and go through the same process as the old die; but the die-holder or case can be used for an unlimited time. Thus the loss when dies are sold for old iron is trifling. 7

Having thus" described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. A- die for wire-drawing having a central opening and sides tapering from top to bottom, the upper outer part of said die being provided with a laterally-projecting lug, so as to be held'without turning in a suitably-reeessed die-holder, substantially as specified.

2. A die for wire-drawing detachable from the die-holder, and having a central opening with tapering sides tapering from top to bottom, the upper outer part of said die being provided with a laterally-projecting lug, in combination with a die-holder provided with an opening adapted to receive the die, said opening being provided with a lateral recess near its top adapted to receive the die lug, substantially as specified.

3. The combination of the die'holder A, having conical openings, each provided with thereccss C, with the detachable dies D fitting into said openings, and each provided with the funnel-shaped opening D d, and the lug E to enter the recess 0 and prevent the die from turning when being reamed, substantially as specified. I

In testimony whereof I at'fix my signature in presence of two witnesses.
