I 4 solaires. (cino- 148)` v im' 'lhepresent invention relates lto wire straightening or killing devices and embodies,v more parparent as it; is described inY greater detail in v'connection with the accompanying drawing,

ticularly, a. straightening or killing device that v,

A permits the wire to be operated upon without subjecting the wire to a, permanent set."

More particularly, the invention embodies a deviceI of the above character thatis particularly wherein:

Fig. 1 is a plan view showing awire straightening or killing device constructed in accordance with' the present invention.

well adapted to be used with continuous wire f dra ing machines and operations and wherein a p rmanent set in the wire is avoided.

In continuous wire drawing operations, there is a tendency for internal strains to accumulate Wwithin the wire. resulting in the wires becoming unmanageable by reason of its taking a permafnent set a ound'the wire drawing blocks.

` When a coil of such wire is released and allowed to lie flat on the floor, the excess curvature or corkscrew condition present in the wire when first confined in a coilabout the drawing block, causes the wire to become unruly, and when the wire is released from the confining bands, it

That

tends to form corkscrews and become otherwise I tangled.

A straightened or killed wire, on theother hand, has a curvature not much exceeding that of theJwire when first confined in a coil, and if the wire is released on the floorit will remain in approximately one plane and will not tendtc form corkscrews or become tangled. The "straightenng or killing of wire thus-elimiinates its otherwise normal tendency toward unruly behavior.

AAn object of the present invention is to provide a straightening or killing device by means of which wire may be straightened or killed effectively and without the difficulties attendant upon thel presence of a permanent set formed in the wire. y

A further object of the invention is to provide a wire straightening or killing device wherein the straightening or killing operation is per- .formed without,` imparting a'permanent set to the` wire.

The foregoing objects are attained by providing l Further objects of the invention will be ap- 'r Fig.v 2 isa view in front elevation of the device of Fig.V 1.

Fig. 3 is a view in transverse section, taken on the line 3-3 of Figl 2 and looking in the direction of the arrows.

Referring tothe above drawing, the wire drawing' device is shown as being formed with a base `It) having an elongated boss Il which is provided A flange I8 may be provided and formed with an aperture I9 by means of which the base may be securely mounted in position. At the other end of the base, threaded apertures 20 and 2I are provided by means of which av cooling fluid may be introduced into and withdrawn from the base. In order that the circulation of the fluid may be accomplished in a desired fashion, the aperspindles and the base.

ture `2I communicates with the compartment,

and suitable'gasket or sealing material 25 provided toinsure a fluid tight Joint between the spindles are formed with axially hollow portions 26 and apertures 21 to facilitate movement of the 4cooling fluid into th spindles to effect the cooling thereof.

Rollers 28 are journaled on therspindles by means of roller bearings 29, the `rollers being formed with grooves 30 over which the wire passes as indicated by the dot-and-dash line in Fig. 1. Counter pins 3| may be provided to secure the rollers in position on the spindles 22 and, in operation, the wire is drawn through the rollers to effect the straightening or klling thereof in accordance with well known practice. The circulation, of a cooling lfluid through the base maintains the spindles and rollers at such a temperature that undesirable heating of the drawing, it is not to be limited save as defined inthe appended claims.

I claim: 1. A wire straightening or killing device comprising a`base, a plurality of spindles carried -by the base, rollersy on the spindles over which wire is passed to effect the straightening or killing thereof, said spindles and base being hollow, and

means to introduce a cooling fluid into the base and spindles.

2. A wire straightening or killing device comprising a hollow base, a plurality of hollow spindles on the base and having the hollow portions thereof communicating with the hollow portion of the base, means on the spindles over which wire is passed to effect the straightening or killing thereof, and means to circulate a cooling uid through the base.

3. A wire straightening o'r killing device comprising a hollow base, a plurality of hollow spindles on the base and having the hollow portions thereof communicating with the hollow portion of the base, rollers journaled on the spindles over which wire is passed to eiect the straightening or killing thereof;v and means to circulate a cooling fluid through the base.

4. A wire straightening or killing device comprising a hollow base, a plurality of hollow spindles on the base, and having the hollow portions thereof communicating with the hollow portion of the base, rollers journaled on the spindles over which wire is passed to effect the straightening or killing thereof, a baiiie in the base, and means to circulate a cooling fluid through the base, said baille directing the flow of the fluid along the spindles.

5. A wire straightening or killing device comprising a hollow base, a plurality of spindles on the base with a portion of each spindle extending into the hollow portion of the base, means on the spindles over which wire is passed to effect the straightening or killing thereof, and means to circulate a cooling fluid through the base and in contact with` the spindles.

6. A wire straightening or killing device com,- prising a, hollow base, a plurality of hollow spin'- dles on the base with a portion of each extending into and having the hollow interiors thereof communicating with the hollow portion of the base, means on the spindles over which wire is passed to eect the rstraightening or killing thereof, and

means to circulate-a cooling fluid through the4 base and along the spindles.

7. A lwire straighteningor killing device coinprising a hollow base, a plurality of spindles on the base with a portion of each spindle extending into the hollow portion of the base, means on the spindles over which wire is passed to effect` the straightening or killing thereof, the extended portion of each spindle being provided with a passage therethrough, and means to introduce a cooling uid into said base for circulation in contact with the extended portions of said spindles and through the passages contained therein. y

8. A Wire straightening or killing device comprising a hollow base, a plurality of hollow spindles on the base with a portion ofeach extending into and having the hollow interiors thereof communicating with the hollow portion of the base, means on the spindles over winch wire is passed to effect the straightening or killing thereof, the hollow interiors of said spindles extending into the portion of the spindles adjacent which the wire is passed, and means to introduce a cooling fluid into 'said base for circulation about the extended portions of said spindles and into the hollow interiors thereof.
