WILLIAM T. AsIIoItoFT, or WATEEBU'RY, CONNECTICUT.

WIRE-STRAIGHTENER.

Application filed March 5,

To all whom it may concern:

Be it known that I, WILLIAM T. AsII- onor'r, citizen of the United States, and resident of Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvement-s in Tire-Straighteners, of which the following is a specification.

My invention relates to new and useful improvements in wire straighteners, such as are used in connection with automatic wire working machines of various sorts, and through which the wire is fed from a reel.

It is the object of the invention to generally improve upon devices of this kind and particularly to simplify and cheapen their construction so that the same can be made at a moderate cost;r to provide a straightener that will operate upon different sizes of wire and turn it out perfectly straight and suitable for any class of manufacture, causing very little scrap or waste when being used.

Further objects of the invention will hereinafter appear: and to these ends the invention consists of a device for carrying out the above objects, embodying the fea-- tures of construction, combinations of elements, and arrangements of parts having the general mode of operation, substantially as hereinafter fully described and claimed in this specification and shown in the accompanying drawings, in which- Figure l, is a top plan view of my improved forni of straightener. Fig. 2, shows a central vertical longitudinal section through the straightener with wire threaded therethrough. Fig. 3, is a vertical longitudinal section of the straightener mounted for rotation and with guide plug in lowered position as when introducing the wire end, and Fig. 4, is a cross section of the straightener taken on line 4 4 of Fig. 2.

Referring to the drawings 5 represents a bracket for supporting the straightener and 6 a bearing of the bracket in which a pulley arbor 7 is supported and in which spindle of the straightener is rotatively mounted. The body 8 of this straightener is of a general elongated cylindrical form though somewhat larger through its central portion 9 than the spindle ends 10. The wire 11 is passed longitudinally through the straightener, that is into one end and out from the other. The body 8 is slotted in one side as at 8 longitudinally from one Specification of Letters Patent.

end to the other to form in part a passage way for the wire lto be drawn through. This slot can be cut with a miller or other 'suitable machine by running the cutter thereof clear through the entire length of the body before the plug is put in position, which obviously means an inexpensive operation. The outer ends of this slot are reamed out slightly to form a socket for the guide tubes 12 through which the wire is passed. A transverse bore 13 is formed through the enlarged central portion 9 of the body and in this `bore is fitted a wire guide plug 14 having a cross groove 15 in one end through which the wire is drawn in the manner shown in Fig. 2. A set screw 16 secured in the body serves to engage the plug and hold `it in its adjusted positions as for instance that shown in the drawings and whereby the wire is guided off from the center or direct line of travel through the straightener. This plug is thus made detached so that it can be lowered as shown in Fig. 3, to permit the wire to be readily insert-ed, and after which the plug is again shoved out to the desired position and secured by the screw before mentioned. This serves as a great advantage in the introduction of thick wire which is hard to introduce through some forms of straighteners. The position of this plug may obviously be varied according to the particular thickness and quality of wire to be straightened.

Should the tubes become worn and require to be changed they can be easily removed by loosening their set screws and other tubes substituted.

After the wire has been threaded through, the plug is adjusted and secured in position, the straightener is suitably rotated during the feeding of the wire through the device. This form of treatment serves to bend the wire in various directions with the result that it emerges from the tool perfectly straight.

It will be obvious that this straightener can be used in connection with different forms of wire working machines and also in a different kind of arbors for driving the same, from that herein shown.

Having thus described my invention what I claim and desire to secure by Letters Patent is In arotary wire straightener of the class described, the combination of an elongated tubular body having a longitudinal slot Signed at Waterbury, in the county of 10 clear through one side thereof, guide tubes New Haven, and State of Connecticut, this itted in the two end port-ions of said slotted twenty-fth day of February, A.
