Application filed October 21, 1909. Serial No. 523,908.

To all whom it may concern:

Be it known that I, ALBERT H. NELLER, a citizen of the United States, residing at F airfield, in the county of Jefierson and State of Iowa, have invented a new and useful Improvement in Vire-Straighteners, of which the following is a specification.

My invention relates to machines for straightening wire from the coil, and it consists of means for holding a coil of wire in a vertical loosely hanging position and taking the wire to the straightening mechanism from the upper edge of the coil, also,'of an improved form of the straightening apparatus, and in other features set forth in this specification, and more definitely pointed out in the claims.

In the accompanying drawings forming a .part of this specification, Figure 1 is a perthe framework being broken away. Fig. 3

is a transverse section on line 3-3 of Fig. 1. Fig. 4 is a cross section on line 4-4 of Fig. 3, the ends of the framework being broken away. Fig. 5 is a transverse section on line 55 of Fig. 1. Fig. 6 is the same on line 66 of Fig. 1, the ends being broken away. Figs. 7 and 8 aresectional detail views which will be explained here ina-fter.

Referring to the drawings, A represents a timber to which a post- B and legs C are attached, forming in efiect a frame or trestle. D is a roller mounted at one side of the trestle on a laterally projecting horizontall disposed axle E, as shown most plainly in ig. 7, which is a transverse section of the roller D near its outer end. This axle is preferably tubular and is driven into or The coil of wire ii is placed upon the roller D and one of its ends is passed around guide sheaves G and G, the former being attached by an iron to the post '13 near its lower end, and the latter, to iron plates M secured to the outer end of the timber A.

From the sheave G the end of the wire is passed to the straightening apparatus which consists essentially of three geared wheels H, I and J, adjustably mounted so the wire may be passed between them.

These wheels are each provided with a deep groove in the center, as most. plainly shown in Fig. 8, which is a horizontal section through the center of the wheel H, showing its immediate connections. The wheel H is mounted on an axle which is preferably held in place by two straps of iron K, se-

cured to the timber A, one on each side,-

with the axle between their upper ends. The wheel J is mounted on an axle secured to a lever L which is pivoted to the timber A. It; is preferably composed of a bar of iron having its lower end forked so that the wheel J may be mounted on an axle between the forks and that these ends may straddle the upper edge of the timber A and be pivoted thereto.

The wheel I is mounted on an axle which is secured between the adjacent ends of two sets of iron strapsN and 0, one member of each set being on each side of the wheel I.- The other ends of the straps LT are jointedly connected to the outer ends ofthe axle upon which the wheel H is mounted, and the other ends of. the straps O are connected in a similar manner to the outer ends of the axle upon which the wheel J is mounted.

The lower end of one of the forked ends of the lever L is extended down'below the timber A and is provided with a spring pressed pawl P which is adapted to engage and beheld by a'rack .Q secured to the post B. The upper end of the lever is fitted with a hand piece R which is connected to the pawl by a rod 1' in the usual way. In Fig.1, the main part of the lever L passes on the rear'side' of the timber A, while in be raised and lowered. ln bringing the wheels H and J closer together with the lever, and raising the wheel I, the space between them made by the grooves in the wheels, will be increased so that the end of the coiled wire may be readily inserted therein. By bringing the lever back so as to move the wheel J away from the wheel H and thus lowering the wheel I, the bot tom of its groove will press the wlre against the bottoms of the grooves in the wheels H and J, :40 as to take out the bend of the coil and leave the wire apprb imately straight, as shown in Fig. 2.

By separating the wheels H and J too far and bringing the wheel l down too much, a bend may be made in the wire in the opposite direction but this is regulated approximately by the pawl P and rack Q, which may be set to hold the wheels in the proper position to straighten the wire. As a further means of adjustment. a guide sheave S is mounted in a standard T which is adiustably secured to the timber A. By this ineans the sheave may be adjusted up or down so the wire in passing under it will be made approximately straight. It is necessary that the wheel be set low enough to spring the wire slightly in the opposite direct-ion to make up tor its rec-o l or its spring backward when released. Tlns will bring the wire up against the sheave which may then be adjusted exactly to the proper position to properly straighten the wire.

The adjustment of the standard 'lis pretcrablv made by a coiled spring U and a thumb-screw Y, the former being adapted to raise the standard T- and the latter to lower it. An adjustment sidewise may also be provided for it necessary. The wire is carried through the wheels by means of power applied to one of them. preferably the wheel H. In Figs. 1 and 8 a crank X is shown connected to the axle of wheel H by means of which the machine may be operated. The machine is also preferably provided with a gage and means for cutting off the wire in desired lengths. A piece of hardened steel Y having a hole with a cutting edge through which the wire passes is secured to the upper portion of the stand ard T. Another piece of hardened steel 2 having a similar hole is pivoted to the piece Y by means of a pin or axle 3 so the holes will coincide while in normal position. The lower end of the piece :2 is elongated and a lever 4 having a curved upper end 5 is pivoted to it. The wire being in the hole, and the lever 4: being raised, the end 5 will come in contact with the side of the standard T and the cutter 2 will turn in the form of an angle or V in cross section to receive and hold the straightened wire, is atlixed to the rear end of the timber A, and a gage T is adjustably secured to this bar. The gage is preferably fitted with a clamping piece 8 adapted to catch over and slide on the bar 6 and a set-screw 9 to hold the gage in position on the bar. To hold the machine in position and to prevent it from upsetting with a heavy coil of wire on the roller at one side, braces or stays 10 are securedto the post B and legs C. These braces are provided with an opening near the center through which a threaded hook bolt 11 having a threaded nut is passed. A screw eye 12 is fastened to the floor or to a timber below and the hook f the bolt 11 is inserted in the eye of the screw as shown in Fig. 1. In straightening coils of wire of different sizes the guide sheave G may be placed higher or lower on the post B to suit the size of the coil. Also the guide sheave G may be set in or out to suit the size of the coil by adjusting the plate M in or out on the timber A. In this way a coil of wire of different sizes may be hung upon the roller D without having to be rewound or made to lit the roller and one of its ends passed around the guide sheaves G and G and through the wheels H, I and J where it is straightened. then through the holes in the cutter blades 2 and Y and to the gage 7, so that it may be cut in pieces of uniform lengths; or it wanted to straighten the wire only, the cutters and the gage may be dispensed with. This is a simple easily operated machine and will do its work well either tor straightening alone. or to straighten and cut the wire to lengths.
