WIRE S TRAIGHTENING APPARATUS Filed April 6, 1928 Inventor Attarnqy Patented Jan. 14, 1930 UNITED STATES JOSEPH KOENIG, OF KAMPSVILLE' ILLINOI'S,

WIRE-STRAIGHTENING APPARATUS Application filed April 6,

The present invention relates to wire straightening devices and has for its principal object to provide a device of this character having a pair of clamping aws between which the wire may be placed and means for ad justable engagement therewith, whereby upon the pulling of the wire through the clamp, the kinks and other bended portions of the wire will be straightened out. The invention is adapted particularly for use in connection with the straightening of the baling wire so that the same may be reclaimed and again placed in use.

A further object of the invention is to provide an apparatus of this character of a simple and practical construction which is hand operated, strong and durable, efficient and reliable in performance, inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the special construction and combination of the various elements comprising the invention, reference being had to the accompanying drawings, forming a part hereof, wherein:

Figure 1 is a side elevational view of the apparatus, and

Figure 2 is an end elevational view thereof.

Referring now to the drawing in detail, the invention comprises a base 5 having a pair of standards 6 extending upwardly in spaced relation adjacent the ends of the base and connected at their upper ends with the longitudinally extending frame member 7.

Each of the standards 6 is formed of a pair of spaced parallel uprights 8 as clearly shown in Figure 2 of the drawing, and disposed be tween each of the uprights and extending between each of the standards is arranged a stationary clamping member 9, secured to the standard by means of bolts or the like 10. The upper face of the stationary clamping member 9 is formed with the longitudinally extending groove 11 and arranged above the stationary clamping member is a vertlcally movable clamping member 12, likewise disposed between the uprights 8 of each of the standards and extending longitudinally above the stationary clamp. The under side of the movable clamping member is also 1928 Serial No; 267,888.

formed with a longitudinally extending groove'13' cooperating with the groove 11 to providea seat forrthewire-to be straightened; To theupper' side of; the movable clamping member 12 is arran'geda leaf spring 1:4-hav-- ing its opposite ends attached adjacent the ends of: the clamps and: arched upwardly towardiltscenter as clearly shown in Figure 1 of the drawings. Adjacent the center of the spring 14 is formed an opening through which the adjusting screw 15 is inserted, having a head disposed beneath the spring and a nut 17 aranged on the adjusting screw above the spring, whereby to firmly secure the adjusting screw thereto. The upper portion of the adjusting screw 15 is threaded through a notch 18 secured between the upper longitudinally extending frame member 7, by means of bolts 19 or the like.

The upper end of the adjusting screw 15 extends above the frame member 7 and is formed into an operating handle 20. At one end of the clamping member 12 is arranged the grease cup 21 adapted to feed a lubricant to the grooves 11 and 13 forming the feed or track for the wire. In the operation of the device, it is apparent that the wire to be straightened is slid in the grooves at one end of the clamp and by pulling the wire between the clamps it is apparent that the kinks, twists, or other bended portions thereof will be straightened out. The upper clamping member 12 may be adjusted with respect to the stationary clamping member 9 so as to regulate the same to accommodate wire of various gauges and also to regulate the clamping pressure upon the wire when the same is I being drawn between the clamping members. By interposing the spring 14 between the upper clamping member and the adjusting screws 15, a yielding action will be permitted in the movable clamping member, should any extreme bends or kinks be encountered in the wire. 7

It is obvious that the invention is susceptible of various changes and modifications, without departing from the spirit or scope of the invention or sacrificing any of its advantages, and I accordingly claim all such forms of the device to which .Iam entitled.

Having thus described my invention, What I claim as new is:

A wire straightener comprising a pair of upwardly extending standards having a horizontally disposed member attached to their upper ends, a stationary clamping member extended between said standards, 7 a movable clamping member disposed above said stationary clamping member and slidably carried by the standards, there being a groove formed in the opposed faces of each of said'members cooperating to provide a seat for the wire,means for lubricating the seat, an adjusting screw carried by said horizontal member for said movable clamping member, and spring means disposed longitudinally above said movable clamping member with its ends attached to said opposite ends of said member and means for rotatably attaching the screw intermediate the ends of the spring for vertical movement with said screw.

' In testimony whereof I afiix my signature.

' JOSEPH KOENIG.
