To all whomc't may concern.-

'Be it known that we, MABcUs BEEMAN and JOHN F. KITCHEN, residents of Meadville, in the county of Crawford and State of Pennsylvania,. have invented a new and useful; Improvement in Devices for Straightening Metal Strips, of which the following is a specification.

This invention relates to devices for straightening metal strips, and more particularly to devices for straightening strips formed by bendin wire into a series of loops to form a fa ric to afterward cut into suitable lengths to serve as garment stays.

The fabrication of garment stays from a high quality of steel wire by bending the same into a series of loops produces a strip which curves and kinks to varying degrees, due to the action of the bending devices,

variations in the temperand twistof the wire and other causes. The strip or fabric must be straightened before the product can be used for garment stays.

The resent invention has for its object to provide a device for straightening such strips, by means of which the strip is entirely relieved of its curls, bends or curves, and caused to be strai ht and flat, and which device is so arrange as to be readily adjust-ed or varied to exert varying degrees of efiect on the strip according to the varying conditions of the latter.

The invention vcomprises the construction and arrangement of parts hereinafter described and claimed. t I

In the accompanying drawings Figure 1 is a side elevation of the device; Fig. 2 is avertical transverse section on the line 2- 2,' Fig. 1; Fig. 3 is a similar view on the hue 3-3, Fig; 1; Fig. 4 is in part a plan view and in parta horizontal section on the line 4-4, Fig. 1; and Fig. 5 is a diagrammatic view of a modified form.

The frame of the device is a casting comprising the base 1, and an upright or web relatively low portion '2 and a.

having a relatively high portion 3. The base 1 near one end is provided with an opening in which are set guide or wear blocks 4:, 5, and grooved to form a. passage for the strip ltherebetween and secured by screw 5 work-" a threaded 1101s in the base 1.

e strip 7 to be straightened passes updevice between the guide or wear blocks 4 and 5-but it is not intended to exert any -;fr1ct1on or pressure thereon at this point,

The'strip passes thence over an idle guide roll 9, wh ch rotates on a suitable, pin mounted 1n the web. The roll 9 is grooved to receive the strip and cooperating-therewith isa tension spring ll -which presses on the strip to exert the necessary tension thereon. This spring isseured to a headed stud or bolt 12 rotatable in a hole in web 2, and is frictionally held thereon by a nut- 13 and spring 14 on its one end drawing its head 15 against the low portion 2 of the web. By means of the nut the trio 'on can be varied as desired to hold the spring 11 with any desired tensionon the strip tobe straightened.

The-stud or bolt 12 .can be turned or rotated in either direction, by means of handle 16, to any desired position, the friction of nut 13 and spring 14 being suificientto hold the stud or bolt in adjusted. position. For convenience in inserting the strip to be straightened the tension spring 11 can be swung entirely clear of roll 9, if so desired.

From the idler roll 9 the strip 7 passes over a swinging roll 18, thence over a small roll or stud 19, and thence over a horizontal grooved guide 20 and out at the rear of the machine. The guideblock 20 is secured to the web 3 of the frame by means of screw 21 or other suitable means. The member 19 is a small roll running idly on a small arbor or shaft 22, provided with a head 23 to keep the roll in place and clamped in a split block or bushing 24, securedin an opening in web 3 and clamped thereon by suitable means.

The swinging roll 18 is journaled on a headed stud 27 securedto a circular member '28 set slightly eccentric to the axis of the sition'for inspection of the straightening rolls, and for convenience in inserting the strip to be straightened.

wardly into the forward or front part of thev (Q PatentedJam21, 1913.

The ircular member 28'carrying the roll the quality thereof and the amount of stress to be applied thereto to straighten the same.

In Fig. 1 the dotted line position a indi cates the extreme lower position of the .roll 1-8 in which the strip can take a straight course fronridler 9, under' roll 19 and over I guide'20. At f is'iudicated the extreme upper position of roll 18 in which position thestrip-7 is given maximum deflection. It can be held at any point between these two extremes, and is adjusted by. the operator by means of hand wheel 35. The operator watches the effect of the rolls on the strip.'7 and adjusts the position of roll 18 back and forth depending upon whether the device is failing to take all of the curvature out of the strip or is overdoing'the same. The roll is stopped in its lowermost position by abutting the guide 20, and in its extreme uppermost position by approaching the roll 19 so closely as to be stopped by the strip 7 between said rolls. i The roll 18 is held'in adjuste'd position frictionally by means of helical spring 37 interposed between hand wheel 35 and a plate 38 surrounding hub 34 and bearing against the outer face of the'swinging plate 29. The spring draws the, rotating member '28 outwardly and'brings a-flange 39 on its periphery against a shoulder on plate 29 with suflicient pressure to frictionally hold the member 28 with roller"1 8' in any position to which it may be moved ,by means of hand wheel 35. p a

The strip 7-may be drawn through the device by hand or by any suitable traction device, such as a reel, spool or the like, but

device byimeans of'a pair of driven "rolls placed at the rear of the device and pinching the strip therebetween. As such traction devices are well known in the art, the action thereof will be readily understood.

In Fig. 5 we have illustrated somewhat diagrammatically a modified form of device in which the fixed guide 2O is replaced by a movable guide. As shown the guide consists of an idle roller or wheel 42 mounted for rotation on a stud or pin 43 secured to the high portion of the web 3 and located below and slightly in advance of the stud 19. Preferably the roll 42 is. grooved to receive the strip 7 in the same manner as the guide 20. Other forms of guide will readily suggest themselves.

The operation of the device will be readily understood from the foregoing descrip tion in connection withthe drawings. The

device is of simple construction and readily strips, the combination of a deflectiontathestrip to instantly meet the ,varying conditions of the strip to be straightened: the parts subject to wear are readily accessible and can be easily replaced in case of=excessive wear.

Ve desire to be understoodthat front and rear, appearingdn the specification and claims, are used with reference to'the places or direction of entrance and exit of v the strip from the device. In other words, the guides nearer, along the line of movement of the strip, to its place of'entrance may be considered as in front of those guides which, are nearer to the place of exit. of the strip, which is at the rear of the device. i

\Vhat we claim is:

adjustable to give any desired amount of a 18 is provided with axial projection or hub 34 to which is secured a hand wheel 35' by means of which the plate 28 can be rotated to vary the position of the roll 18 to. more or less deflect the strip 7, depending on 1. Ina device for straightening metal-- strips, the combination of a pair of guides arranged'one on each side of the strip and adapted to direct the same, a roll adjustably mounted to swing'around one of said guides and across the space between said guides to deflect the strip, and means ftir holding said roll in adjusted position. i
