r anw ne aenanrus SPECIFICATION forming part of Letters Patent No. 431,499, dated July 1, 1890.

Application filed November 13, 1889. serial No. 330,202. (No model.)

,Ilo all whom it may concern:

.. certain features of construction and in combination of parts hereinafter described, and

pointed out in the claims. In reducing, for 1nstance,w1-re of medium size to the very small sizes suitable for bolting-cloth andvarious other purposes, the wire is drawn "through a series of reducing-dies, and, the motion of the wire being usually quite rapid, the friction between wire and dies is likely to generate so much heat that the dies are frequently injured thereby. More especially where diamond dies are used these are liable to be cracked and broken if they become heated to any considerable degree. I have therefore devised the mechanism illustrated in the ac companying drawings, in which the dies are constantly submerged in suitable lubricant.

Figure 1 is a plan. Fig. 2 is an elevation in section on line a: :1:,Fig. 1. Fig. .3 is a corresponding elevation in section, showing a modification hereinafter described.

A represents a shallow vat for holding lubricant, the vat being constructed usually of cast-iron.

B and O are horizontal parallel shafts, the same extending into or over the line of the vet substantially as shown, these shafts out side the vat being intergeared in any suitable manner-for instance, as shown by means of engaging twin gears m m. One shaft is provided with a suitable drivingpulley-for in stance, pulley N-and the one shaft is providedwith a beveled gear 0, that engages a bevel-gear P, the latter being mounted on the upright shaft 12, on which shaft is also mounted the receiving or winding drum l). The trans mitting mechanism, however,.may be varied indefinitely, according to circumstances or to the judgment of the builder.

. F is the reel on which the coil of wire is placed preparatory to drawing and from which the wire leads to one of the draft-drums B O, these drums being mounted on the respective shafts B and (J. The lower sections of drums B O extend well down into the vat,

so that when the vat is partially-filled with lubricant the lower section of these drums is submerged.

- In Fig. 2 wire d from thereel is shown leading'first around drum B in the direction of the arrow, and from thence leading in the opposite direction around drum C, from whence it returns to drum B, and so on, the wire eventually leading to the receiving-drum D.

E E are dies arranged in series, and for in are esedies in place are provided ribs a a, the same projecting upward from the bottom of the vat, these ribs having transverse slots for the passage of the wire.

D, as shown, is only for simplifying the gear-' ing. Otherwise this drum may be placed in any desired position.

The rat A is kept supplied with suitable lubricant to cover the dies, and hence the dies, drums B O, and the wire are kept comparatively cool. In case of diamond dies be- The dies are held in place against these ribs by ing employed the diamonds are set in a small l v metal disk, and it is these disks that engage ribs a, the disk and die proper being known to the trade as die. The only object of rotating drums B O in opposite directions and crossing the wire, as shown in Fig. 2, is to be able to use two series. of dies, both of which are submerged. In case fewer dies are needed, so that one series Will besufficient, drums 1B 0' may just as well be rotated in the same direction, in which case the wire would lead around the drums, as shown in Fig. 3. In such case gears m 0% could be made smaller to make room for an intermediate gear, or the gearing could be arranged in any manner to accomplish the object.

' What I claim is- 1. In .a wire-drawing apparatus, the combination, with a vat for containing a lubricant,
