l'lettfrrs Patent No.' 89,869, dated May 11, 1869.

The Schedule referred to in these Letters -Pateut and makingvpart `of the saine.

ToA all whom "it ma/y concern V Be it known that I, ROBERT KENT, No. 150 Sands street, in the city of Brooklyn, in the county of Kings, and State of New York, have invented certain new and useful Improvements in Dies for Reducing Wire; and

I do hereby declare that the followingis a i'ull, clear,

. Thisdie is made of chilled iron, or hardened steel.

A is the lower part of said die, its two sides, a a, extending upward from either end, as shown in'iigs. 1,v

l2, and 4.

B- is the upper, or middle part, fitted exactly into A and jointed,I or hinged, by a pin, O, to the upper part ofthe arrnsof'A, as shown. l

B, i'jn' Iig. 2, is shown opened out.

Its lower face, or edge, b b, is 'bevelled, to allow it t0 swing open on one side.

Said bevelled face, `or ledge its exactly against a complementary face on V -The openings, or dies, c d e f, through which the wire is drawn, are formed on this bevelled joint, but theI axes of said openings, instead of following the j oint, are at right angles to the sides of die, as shown in transverse section, g. 3.

Said openings are alsotapered, being wider on that side toward which B opens.

. rIhe centres of the small ends of ltaper-holes, or dies of large ends of tapenholes or dies are above the line' of joint on the other side, the taperof hole'and bevel of joint being adjusted t0 each other, so as not to pre.=

vent B closing over the wire.

'This die may be made of any required size.

To operatethis, the lower part A may be held in a. .vise,` or any-other suitable arrangement for 'that pur# pose, with the small ends of' dies, or taper-holes toward the operator.

B isvthen openedout to position shown in g. 2, the end of wire to be reduced is entered the required length, laid in its proper die, or lower half of taperhole in A. B is pushed into its proper place over the wire, as shown in figs-1,3, and 4, and the wireis now drawn through, in the direction indicated by the `ar rowsin gs. l and 3, and thus the wire is reduced on the end, that it may enter the solid die in draw-bench, through which .it is subsequently drawn, and formed into finished wire. Or, this improved diemay -be placed in the draw-bench, in place of the usual solid die',wl1en it is required to reduce the wire only, 'and reduce the whole length of wire coils, and, in this case, the endsof wire would not require reducing,.as in the solid die. What I claim as my invention, and desire t0 se'- cure by .Letters Patent, is-

Th'e herein-described apparatus for reducing wire,

when constructed and operating substantially as set forth.
