invented new and useful Improvements, 1n

Machines for Forming Metallic Stays for Garments, &c., of which the following, taken in connection with the accompanying drawings, is a full, clear, andexact description.

This invention relates to the class of machines which are designed to bend wire into serpentine shape, so as to' produce therefrom a metallic arranged contiguously side by side and alternately in reverse positions. K The present invention consists in an improved construction and combination of the wire-bending machine and auxiliary devices connected therewith and operating to produce improved results, as hereinafter explained and summed in the claims. The accompanying drawings illustrate the improved machinefor bending wire into serpentine shape. v

. tical longitudinal section of that portion of the machine which is provided with the anvil and hammer for straightening the metallic garment-Sta Fig. 7 is a plan view of the push-bars w 'ch propel the said metallic garment-stay to the anvil. Figs. 8 and 9 are enlarged side views of one. of the cams which actuate the'wire-carrying bars and one of the cams which actuate the wire-bending fingers. Fig. 10 is an enlarged .vertical transverse .sec-

tion on line Y Y in Fig. 2,, and Fig. 1 1 is-a verti- 5o bed-plate BL Betw'eenthe said'walls are the callongitudinal section on line Z Z in Fig. 10.

Similar characters of reference indicate corresponding parts. 1 A A represent two. arallel vertical Walls which? is bolted or.

wire-carrying bars a. a), which are pivoted at a to the walls A A. The front-end of each of these bars is provided withupwardly-projectband composed of a row of loops,

opposite sides of ing pins 1) b arranged one back of and at a" short distance from the other.. Said bars are oscillated alternately by means of the following mechanisms, to wit: Adjacent to'the rear end of the bars an a 's a rotary horizontal driving-shaft C, disposed at right angles to said bars and mounted in bearings on pedestals D D. To the driving-shaft are attached two grooved cams F F, the grooves of which are shaped correspondingly, but in reversed positions. To the rear end of each of the bars a a is connected a depending arm 0, the lower end of which is bifurcated and straddles the driving-shaft C, as shown in Fig. 8 of the drawings. To the side of the arm 0 is attached a Stud 0, which travels in the camgroove F during the rotation of the cams.

The arm 0 is thus reciprocated vertically and caused to impart oscillatory motion to the bar a.

The object of using the grooved cams is to dispense with the spring usually employed for maintaining in contact with the cam the part of the mechanism which is to receive motion therefrom.

MEADVILLE, PENNSYLVANIA, A.

d and (1 denote the alternately-oscillating wire-bending fingers which are disposed at the front ends of the two wire-carrying bars a, and a and are curved so as to allow each of the said fingers to pass around the end of the bar adjacent thereto.

The free end of each finger is provided with a groove or notch 61, whifli is slightly below the plane of the top of the adjacent bar when in its raised positlon. I preferably provide the fingers d and (1* each with two notches (1, arranged one belowthe other, as shown in Fig.

3 of the drawings, to allow said fingers to be reversed and used on either the right or left side of the bars a a The fingers d and (1 are oscillated alternately by mechanism hereinafter described and are timed in their action to correspond to the oscillation of the bars a a ,so as to cause each finger to swing around the end of the adjacent bar and back therefrom while said bar is in its raised position and the companion bar is depressed.

The operation of the machine thusfar described is as follows: Referring to Fig. 3 and assuming the bar a to be in'its raised position I and the machine at rest, the operator inserts the end of the wire (indicated at y) longitudinally close to the outside of the front pin of said bar. The machine being then set in motion causes the finger d to swing in across the end of the bar a and push the wire inward over the front pinb of the depressed bar a where it leaves the wire in the shape of a partly-formed loop, while the finger d swings back out of the way of the bar a), which then rises and causes its front pin to enter into the said partly-formed loop. Then the bar a descends and releases the wire from the front pin of said bar. Then the finger d swings in and pushes the wire over the front pin of the depressed bar a, which then rises and causes its front pin to catch in the partly-formed loop of the wire over said bar. This completes the first loop on the bar a. The second loop is formed by the action of the finger d. In the release of the loo from the front pin 6 the wire is allowed to slip longitudinally and causes the released loop to be caught on the rear pin b and thus form the loops contiguously side by side and slightly overlapping. The continuation of the alternate action of the bars and fingers forms a metallic band composed of correspondinglyshaped loops dis osed alternately in reversed ositions. T e notches d of the fingers d X receiving the wire through them and being slightly below the top of the raised bar causes ed and passing througha horizontal plate a 56 e plate e said post may be raised or lowthe fingers to bend the wire down across the inner edges of the'bars, and thus produce a transverse convexity on the under side of the metallic band formed from the wire. This convexity partly stiffens the said band on one of its sides and increases the flexibility on the opposite side. This feature is es ecially desirable when the described metallic band is to be used for stays.

6 represents a tubular guide which is pivot. ally supported onva post e, so as to allow said guide to yield laterally to the side thrust of the wire in being ushed alternately toward opposite sides by t e fingers dd The guide e is rendered adjustable in its elevation by the poste, having its lower end screw-thread' projectmg from the front of the lower. ortion ls A A. By means of nuts fand f ered and clamped in its desired position. Said adjustability of the guide e is desired to direct the-delivery of the wire slightly below the lane of the elevated wire-carrying bar, as s own in Fig. 1, and to cause the wire to enter into the notch (12 of the finger for the purpose of convexin'g the wire band, as herembefore described.

g denotes wire-tensioning plates, which are ,disposed sideby side to receive between them the wire y, passing to the guide e, and are prov ded on the mnersides with friction-faces of either cloth or rubber or other suitable material by which they bear on the wire longitudinally. Adjustable screws 9 pass through the-plates g, and a spring 9 interposed be tween the head of one of said screws and outer side of one of the plates, serves to apply the requisite pressure to said plates, as more clearly shown in Fig. 4 of the drawings. These tensioning-plates are supported on a post g, mounted on an arm .9 projecting rom a sleeve 9 embracing the post e Said sleeve is provided with a screw-threaded perforation in its side, and into this perforation is screwed the arm 9 the inner end of which engages the post e, and thereby fastens the sleeve on the post. By turning the arm 9 so as to loosen it from the post e the sleeve 9 may be raised or lowered, and thus adjust the tension-plates g to bring different portions thereof in contact with the wire 3 it represents a plate disposed longitudinally over the bars a and a and pivoted at its rear end to the walls A A, as shown at h in Fig. 1 of the drawings. Over the late his a transverse bar 7%, one end of w ich is pivotally connected at h to the to A, and the opposite en vided with a transverse slot 7L through one side thereof and receives through said slot a stud-pin 72/ the upper end of which is screwthreaded and provided with a thumb -.nut 72 which bears on to of the bar, as shown in Figs. 1, 3,-and 4 of t e drawings. Centrally over the plate h the bar it is provided with a screw-threaded vertical perforation through which passes a screw h, bearing on the top of the plate It and sustaining said platea roper distance from the top of the bars can a to allow the bent wire y to pass under the plate h and maintain said wire in a plane to allow the pins b b of the ascending wire-carrying bar to enter the previously-formed loops of the wire.

The wire-bending fingers d d receive their [walls A A, as more clearly shown in Fig. 5 of the drawings. Said eccentrics are formed with annular plates i which rotrude through slots between the sleeves t '1? and have their peripheries notched to aflord the .necessary hold for the operator to turn the eccentrics, and thereby adjust the shafts i of of one of the walls of said bar is prothe wire-bending fingers a greater or less distance apart, and thus regulate the thrust of said fingers. A spring-plate '5 is attached to the front of the walls A A and has its ends engaging the peripheries of the plate i so as to prevent "them from turning around, and

thus to retain the shafts 1'. i in their adjusted position. The lower end of each shaft i rests to it an arm i to which'is connected a longitudinally-adjustable reciprocatingrod L; A spring 1,, surrounding the shaft 'i between the on an adjustable bearing i and has attached arm i and bottom of the lower sleeve i serves to hold the said shaft down on the bearing i which consists of the head of a screw inserted in a ocket in the base A, as indicated in dotted ines in Fig. 3 of the drawings. adjustment of the shafts i '11 is necessary to dispose the wire-bending fingers d d" inthe requisite plane in relation to the wire-carrying bars a a Grooved cams G G (shown in Fig. 9) of reversed contours are mounted on the driving-shaft C, on which the bifurcated rear ends of the rods 'i" ride. Rollers or studs f, projecting from the sides of the rods and engaging the cam-grooves G, impart alternate reciprocating motion to the said. rods. To allow the thrusts of the fingers d d to be regulated to properly cooperate with the pins b b of the bars a and a), the rods i are each formed of a central section 1, which is provided with'right and left threads at opposite ends and-screwed into corresponding sockets 3 3 in the end sections 2 2 of the rod. By means of nuts 4 4 the rod is retained, in its adjustment.

The hereinbefore-described operation of forming the wire band and convexing it on' one side imparts to the said band a tendency to curl or twist longitudinally, so as to hinder its being properly wound upon a reel. This difficulty is overcome by passing the said wire band onto a suitable anvil and subjecting it to the blows of the hammer. The detail construction of said anvil andhammer is susceptible of various modifications which will readily suggest themselves to a mechanic conversant with the use of tools of that character. The accompanying drawings illustrate the preferred construction, in which H represents the anvil, which is in range with the bars a a and is provided with a longitudinal groove H in its top and a depression H in said groove, as shown in Fig. 6 of the drawings. At the rear of the anvll-is a post P, which is provided with a vertical slot I, through which asses a rearward extension of the hammer l which is pivoted to a post P Through the slotted portion of the post P extends a transverse shaft I, on which is mounted a suitable cam 1 which is underthe hammer. The shaft 1 has attached to it a gear 1 which receives rotary motion from the driving-shaft C by a train-of gears I 1 The cam I is thus rotated and caused to in termittently lift the hammer. Over the hammer is located a plunger j, which is guided in;

a vertical channel j, extending through the top of the post P and screw-threaded in its upper end portion. bears a spring 9' which is compressed endwise by a screw 1' inserted in the upper end of the channel j. Said screw can be adjusted to apply the desired ressure on the plunger and obtain the desire force of the stroke of the hammer. A-jam-nut 3', applied to the screw 3' retains it in its adjustment; The

Said

vto the gear-wheel.

The top of the plunger looped wire y, passing longitudinally through the groove H of the anvil H and subjected to the strokes of the hammer I, straightens the wire longitudinally.

To facilitate the movement of the wire to the anvil, suitable push-bars are employed to engage the wire and propel the same. The

referred construction of said illustrated in Figs. 6 and 7 of t e drawin s, in which a block L is disposed in front of t e anvil and provided with a longitudinal guide-groove L, which isin line with the groove H of the anvil and receives the wire through it.' To the said block are pivoted the rear ends of the bars N N, as shown at k. The front ends of said bars are directly over the arms 0 c, which are reciprocated vertically, as hereinbefore described. Said movement of the arms cc imparts oscillatory motion to the bars N N, which, by means of springs l l, are drawn down to maintain them in contact with the arms 0 c. To each of the bars N is pivoted at m a dog I, which is provided on its rear end with a pointed toe P, by which it engages the loop of the wire in transit through the groove L. A spring-fin er Z is attached at its front end to the bar its rear end on top of the dog to insure its engagement with the wire. the bars N cause the dogs Z to alternately push the wire toward the anvil.

0 represents a reel upon which is wound the looped wire passing from the anvil. Said reel is pivotally supported at its ends on two mandrels n 11,, mounted in bearings 11? on the standards R B. On the mandrel n is loosely mounted a ratchet-wheel 11?, which abuts against the inner end of the bearing n Near to the inner side of said wheel is a gear-wheel n fastened to the mandrel, and between the said two wheels is interposed a disk 11, of suitush-bars is and bears with able material to transmit motion by frictional contact with said wheels.

The mandrel 'n, is extended beyond the outer end of the bearing 11* and has its protruding end screw-threaded and provided with a nut n. A spiral spring a embraces the mandrel between the nut and outer face ofthe bearing p and by pressing on said parts it forces the mandrel endwise, and thus causes the side of. the gear-wheel to press on the disk a which by frictional contact tran'smits rotary motion from the ratchet-wheel A stud-pin n projects from the inner face of the wheel nand engages a socket in the head of the reel, and thus imparts rotary motion to the reel. The

ratchet wheel a receives rotary motion from a lever 0, fulcrumed intermediate its ends on a post R and pivotally connected at front end to a rear extensionJ of the arm of the hammer I. The opposite end of the lever 0 is provided with a dog 0, which en-,. gages the ratchet-wheel n In order to" wind the looped-wire band properly and.

' greater than the roller S to allow said ring to an. M

evenly u on the reel 0, a suitable guide is employe to travel back and forth in a line parallel with the axis of the reel and carry the said wire band in transit to the reel. The

construction of the said guide and mechanisms used in connection therewith admits of many variations. The construction shown in Figs. 1 and 2 of the drawings consists of a roller S, disposed in front of and arallel with the axis of the reel and inounte in bearings on standards R R secured to the bed-plate B. Said roller is provided with right and left or crossing grooves p p and is surrounded by a ring 5*, from which de ends a stem v which is fastened intermediate its ends, as shown at 0 to a-horizontal bar o sliding longitudinally in bearin s 0 in the standards R R Beneath the ar 0 and arallel therewith is a track'q, on the side 0 which bears the lower end of the stem 0 On opposite sides of the interior of the ring S are tongues t t, which are inclined in opposite directions corresponding to the inclinations of the right and left grooves p p. The inner circumference of the ring S is sufficiently move toward and from opposite sides of the roller and cause the tongue i; t to alternately engage the right and left grooves p.

ceives rotary motion from an intermediate gear T, meshing with the gear n on the mandrel n of the reel, as shown in Figs. 1 and 2 of the drawings. 9. lug i set in one of the ooves p p, which serves to pry the engaged tongue out of the groove, and thereby cast the ring S in a direction which causes the other tongue to engage the coinciding groove, and thus compel the ring S to move to the o posite end of the roller. It will thus be 0 served that the movement of the ring S is automatically reversed at each of its arrivals at the ends of the roller. The thrust of said ring toward opposite sides of the roller causes the lower end of the stem 0 to be thrown from one side of the trackqto the opposite'side thereof and caused to engage said side, and thereby maintain the ring in position tohold the tongue in the groove of the roller.
