Specification of Letters Patent;

Patented July l (5, 1912.

Application filed March 4, 1912. Serial No. 681,402.

To all whom it may concern:

Be it. known that I, Cnwnnns Gincnvnn, a citizen of the United States, resit'ln'ig at New 'Haven, in the county of New llaven and State of Connecticut, have invented a new and useful Improvements inlllire-Straighteners; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters oi reference marked thereon, to he a full, clear and exact description oi": the same,and which said drawings constitute part of th is application, and represent, in-- Figure l. a side view of a. wire straight ener constructed in accordance with my invention. Fig. 2 a top view of the some. Fig. 3 a transverse sectional view. Fig. 4 a sectional view on the line a/) of Fig. 2. Fig. 5 a sectional. view on the line 0Z of Fig. Fig. 6 a sectional view on the line e-f of F ig. 2. Fig. 7 a front end view of a pair of dies, enlarged. Fig. 8 a top view of a "pair of dies showing one in transverse sec tion. F ig. 9 an inside edge view of one of Fig. 10 a broken side *iew ot' a wire straightener illustrating a modified form of die retaining slots.

This invention relates toan improvement.

-in Wire straighteners; that is, a holder containing a series of dies arranged out oi line with each other and adapted to be revolved as the Wire passes through it, the object of the invention being to so construct the straightening dies so that they will he firmly held in position, and so that the mouth of one die Wlll always be within the range of the opening in the rear of the preceding die and so that the wire may he insert-ed while the device is in motion; and the in vention consists in the construction hereinafter dhscribed and particularly recited in the claims.

In carrying out my invention, l employ a body 2 provided with trunnions 3, t, at the opposite ends by which it maybe supported,

and near the outer end the body is provided with a rounded surface 5 to receive a driving belt, this rounded surface practically forming a pulley. Extendinglongitiulinally through the body and trunnion is a longitudinal hole 6 through which the wire passes.

Extending vertically through the body are a of openings 7 more or less in uuulher according to the number ot dies to be eniployed, and extending transversely throng'h the body at right angles to the openings 7 are a series of circular holes 8 which intersect the openings 7, and these holes are threaded to receive screws Elf 'lhcse holes 8 are connected, so to speak, by a long slot 10. In connection with the head thus formed, I en'u'doy a series ol'alies arranged in pairs. These dies have central portions ll which are substantially circular and adapted to enter the holes 8. The dies are also formed with extensions 12 and 13 on opposite sides of the central portion which extensions lit in the slot 10 and so that the dies whcn'inserted will not turn with rela tion to the body. The inner ends of these dies are cut away to form months 14 which lead to grooves 15 and 1G in the respective dies which together form a round opening for the passage of the wire, these openil'igs corresponding to the size of the wire to be straightened. These dies arranged in pairs are staggered with relation to each other .as shown in Fig. 3 of the drawings, and are held in place by the screws 5); but notwithstai'iding the extent to which one die may he moved out. of line with the next adjacent die, any wire passing through one die will find the mouth of the next succeeding die owing to the extended taper oi the mouth, this extended mouth'being made possible by the extensions at the forward ends of the dies.

"his device operates in the usual way of wire straighteners; namely, a wire is passed through the device and the device rcvolvcd so as to straighten the wire passing through it. But in my device, owing to the provision of the dies with flaring mouths, the wire may be inserted after, or while the device is in motion, thus avoiding the necessity of stopping the device when another wire is inserted and saving the power necessary to start the device in motion after the wire is between the dies. It is apparent that instead of forming a continuous slot 10, the body may be framed with a series of short slots 17, as shown in Fig. ll), it only being necessary to ha vc the slots long enough to receive the extensions 12 and 13 of the dies, whereby they are prevented from turning. It is also apparent without further illuslration, that instead of forming the dies with extensions at the front and rearj'the extension at the rear might be omitted as the OX tension at the front will hold the dies in place, or in fact the dies may be of uniform thickness corresponding to the Width of the slot in which case if a separate slot provided for each die, the ends of the slot will hold the die against longitudinal movement by the direct engagement with the head.

In either case the longitudinal movementof the dies is by engagement with the head and not dependent upon the screws.

I claim 1. A wire straightener comprising a body having a longitudinal hole through it for the passage of the wire, said body formed with a series of transverse threaded holes, a slot intersecting said holes, combined with a series of dies each having a portion adapted to enter the transversely threaded holes' in the body, and each die formed with an extension which has a bearing in the said slot, the forward ends of the dies formed with flaring mouths, and screws entering the opposite ends of said transverse holes-and bearing on said dies.

2. A wire straightener comprising a body having a longitudinal hiele through it for the passage of the wire, said body formed with a series of transverse threaded holes,

' a slot intersecting said transverse threaded holes, combined with a series of dies each having a portion adapted to enter the transverse threaded holes in the body, said dies formed with extensions entering. the said transverse slot and the forward ends of said extensions provided with flaring months.

3. A wirestraightener comprising a body having a longitudinal hole through it for the passage of the wire, said body formed with vertically arranged openings and with transverse threaded holes intersecting the vertical openings, slots on oppositesides of saidtransverse holes, combined with dies having central portions adapted to enter the transverse holes in the body, said dies formed with extensions entering the transverse slots, and screws entered into said transverse holes and bearing on said dies.

4. A wire straightener comprising a body having a longitudinal hole through it for the passage of the wire, said body formed with "ertically arranged openings and with transverse threaded holes intersecting the vertical openings, slots on opposite sides of said transverse holes, combined. with dies having central portions adapted to enter the transverse holes in the body, said dies formed with extensions entering the transverse slots, the forward extensions formed with flaring mouths, a nd, screws entered into said transverse holes and bearing on said dies. 1

,In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
