Be it known that 1, WILLIAM F. SMITH, a

citizen of the United States,

Brooklyn, in the of New York,

residing at county of Kings and State have invented a certain new and useful Improvement in Wire-Straighteners, of which the following is a full, clear,

concise,

This invention ers,

and exact description.

relates to wire straightenand has for its object the production of a wire straightener which is adapted to be used with a'plurality of sizes of wire.

The features of this invention are the means for adjusting and maintaining the parallelism of two separate sets of rollers, means for positioning the wire to be straightened without changing the operating adjustment 0 f the rollers, and other details and combinations of parts as will herepanying drawings in inafter more fully appear.

A second plate 30, upon which is mounted a plurality of rollers 31 similar to rollers 16 and having V-shaped grooves in their perlpheries, is slidably mounted within the guides 6 and 9. Coiled springs 32, engaging P1118. 33 in the ends of the plate 30 and pins 34 in the base 5 and guide 9, normally tend to separate the rollers 31 from the rollers 16. The rollers 31 are in staggered relation to rollers 16 so that the wire in passing through will follow a wavy path.

In order to adjust the position of rollers 31 with respect to rollers 16, to maintain the two sets of rollers parallel, and to maintain parallel movement of the rollers 31, wedge blocks 35 are slidably mounted in the guides 6 and 9 in such manner as to engage angular surfaces 36 of the guides 6 and-9 and the sides of the plate 30. A rod 37, one end of which is provided with right hand threads, and the other with left hand threads, engages threaded openings 38 in the wedge blocks 35. To maintain the rod 37 in a definite position with respect to the plate 30 after rollers 31 have been set parallel to rollers 16, nuts 45 are pinned to the rod 37 and rest against bifurcated lugs 46 on the plate 30. To lock the rod 37 in a definite position, a lock-nut 47 is provided therefor immediately below the lower lug 46. To the lower end of the base 5 may be attached guide 50 having an opening 51 through which the wire is led to the rollers. To place the wire in proper position to be straightened, the hand wheel 23 is backed up so as to disengage the plate 15, and the plate 15 then turned about the screw 18, after which the wire may be fed through of the guide 50 and between the two sets of rollers. The plate 15 may then be returned to its normal position and the hand wheel 23 tightened u to maintain the plate 15 in position. To a just the relative position of the two sets of rollers, the 47 is backed up and the rod 37 turned sufiiciently in the proper direction, after which the lock-nut 47 is again tightened. Movement of therod 37 imparts an equal movement to the two wedge blocks 35, which in turn impart to the plate 30 a movement to or from the plate 15, which is parallel to its original position and to the plate 15.

What is claimed is:

1. A wire straightener comprising a base,

a fixed and a movable set of rollers supported on said base, wedge blocks, and a threadon said base, a second plate carrying a set of grooved rollers slidably mounted in said guides, tensioning means normally tending to separate the two sets of rollers, wedge blocks slidably mounted in said guides, and a connecting link engaging said blocks for adjusting the position of, said movable set of rollers with respect to said fixed set.

4. A wire straightener comprising a base, two plates supported by said base, a set of grooved rollers mounted on each of said plates, bifurcated guides mounted on said base, one of'said plates being pivoted at one end and adapted to be held rigid at the other or to be moved about its pivot point to admit a wire between said sets of rollers Without changing the operating adjustment thereof, the otherof said plates being slided on said base, tensioning means normally tending to separate said sets of rollers,

Wedge blocks, and a threaded rod engaging said blocks for adjusting the position of said movable set of rollers with respect to said fixed set.

6. A wirestraightener comprising a base, a fixed plate carrying a set of grooved rollers mounted on said base, bifurcated guides mounted on said base, a second plate carrying a set of grooved rollers slidably mounted in said guides, tensioning means normally tending to separate the two sets of rollers, wedge blocks slidably mounted in said guides, and a threaded rod engaging said blocks for imparting a parallel movement to said movable plate for adjusting the relative position of said rollers.

In Witness whereof, I hereunto subscribe my name this 17 day of April A. D., 1914.
