rnnronar'me-nacnmnj To all whom it may concern:

Be itknown that I LOUIS W. G. FLYNT, a subject of the King of Great Britain, residing at Rochester, in the county of Mom roe and State of New York, have inventedcertain Improvements in Perforating-Machines, of which the following description, inconneetion with the accompanying drawings, is a specification, like reference charactors on the drawings indicating like pa-rts'in the several figures.

This invention relates to punching niachines, and articularly to punching machines for forming. ornamental perforations in stock, such, for example, as toe-caps and other parts of boots and shoes. The machines whichoare generally used for this purpose are provided with a punch which penetrates the stocnintermittingly, a presser foot which engages the stock at apoint at one side of the line in'which the perforations are being formed, and mechanism for feeding the stock to bring different portions of it successively into position to be acted upon by the punch. For forming perforations in a curved or irregular line the stock is turned relatively to the direction in whichit is being fed, and the fulcrum about. which it is turned is the presser foot. Machines of this tynnihave not proved satisfactory forforminw'perforations in both straight and curved "lines because the spaces between the perforati'ons formed in a curved line are not of the same length as those between the perforations formed in a straight line. 1 This is due to the fact that the point about which the stock is turned is located at one side of the line in which the perforations are formed, so that when the stockiis turned about the presser foot in one direction'to. produce a curved line of perforations the point at which the last perforation was made will'bev moved slightly in the direction in which the stock is being fed, thereby increasing the length of the spaces between t perforations, and when. it isftu'rne'd about the presser foot in the other direction that point .will be moved slightly-in the opposite direction to that in which the stock is bein'g fed, thereby decreasing thelength of the spaces between the perforations.

The chief'- bject of this invention is to provide means for insuring that the spaces between perforations formed'in a curved or Specification of Letters Patent. Patented NOV. 30, 1909. Application filed January .31, 1905. Serial-No. 243,504.

irregular line will be of the same length as those between perforations formed ,in a straight line and to this end I have devised a punching machine having a presser foot which engages the stock at 1 point in alinement with the line of perforations formed in the stock, so that when the stock is turned about the presser foot, the point at which the last perforation was made will not be moved either in the same or in the reverse direction to that in which the stock is being fed but will be moved at approximately a .right angle to the direction of the feed.

I have herein shown the preferred form of my invention as embodied in a machine having a punch which penetrates the stock and then moves laterally for feeding the stock, the stock being engaged at a point in the plane of lateral movement of the punch by a presser foot which is moved automatically into and out of operative position. In order that the punch may penetrate-the stock without being subjected to contact with a hard metallic bed. surface, a facing strip of soft and preferably flexible material is interposed between the punch block and the stock being .operated on, said strip being moved step by sfip as the stock is fed, so that a fresh portion-of the strip will be presentedto the punch each time penctrates the stock, and one of the features of this invention consists in' means for guiding said strip in its movement and, when flexible, for winding it into a coil as it passes from the punch block.

Other features of the invention consist in an adjustable worlcgage which can be depressed below the surface of the stocksupporting table when said gage is not in use, novel mechanism for moving the punch laterally, and for varying the extent of reciprocating movement of the punch, and improved means for changing the degree of lateral movement of the punch.

In the drawings, which illustrate the preferred form. of the invention, Figure 1 is a side elevation-of a' punching machine enibodying features of my invention; Fig. 2 is an elevation of the left-hand end ofthe machineshown in Fig. 1; Fig. 3 is a plan view, partly in section, taken on the line y-. z of Fig. 2, showing the cams on the main shaft for actuating the punch, punch carrier, and presser foot bar; Fig. 4 is a view, partiy in section, of the punch bar, punch carrier, and the mechanism for moving it laterally; Fig. 5 is a detail side elevation, partly in section, taken on the line ar -m of Fig. 2, showing the cams on the main shaft and the mechanism for adjusting the roller on the end of the punch. bar; Fig. 6 is a side elevation of the presser foot and the mechanism for moving it relatively to the presser foot bar; Fig. 7 1s a perspective view of the W0] k-gage against which the stock is held; Fig. 8 is a perspective view of the spools on which the facing strip is Wound when flexible and the standard on which said spoolsare mounted; Figs. 9 and 10 are perspective detail views of said spools with the retaining plates removed; Fig. '11 is a detail sectional View showing the means for imparting movement to the shaft which carries one of the spools; and Fig. 12 is a vertical sectional view taken through the stock-supporting table showing the means for guiding the facing strip when flexible.

Referring to the drawings, 2 designates a frame which carries a main shaft 4 having a driving pulley 5 and provided with a cam 6 for depressing a punch bar 8 and with cams 10 and '12 for imparting lateral movement to a carrier 14 in which the punch bar is mounted. The main shaft is mounted in bushings 100 and 101 inthe frame, and the carrier 14 is provided at its upper end with straps 15, 15 that are journaled on said bushings, as shown in Fig. 5, and pivotally connected toa bracket 16 on said carrier is a lever 18. provided with rollers 20 and 21 which cooperate with the cams 10 and 12 on the 1nain shaft. A fulcrum block 22 is ad just'ably mounted in a slot 23 in a stationary part of the frame and is provided with a roller 25 which acts as a fulcrum for the lever 18, so that when the upper end of said lever is moved outwardly by the cams on the main shaft the lower end of said lever will be moved in the opposite direction, thereby swinging the punch bar carrier 14: in the direction of the arrow in Fig. dfor causing the punch to feed the stock, said carrier being moved in the opposite direction, back to starting position, by a spring 11 confined in a stationary part of the frame and bearing against said carrier. By changing the position of the fulcrum block the extent of movement of the punch bar carrier in each direction will'be varied and the distance which the punch feeds. the stock will be changed. The punch bar is provided at its upper end with ears 7 and 7 in which a pin 26 is mounted, said pin having an eccentric portion which carries a roller/2T that cooperates with the cam (5 that depresses the punch bar, said bar being moved upwardly to withdraw the punch from the stock by means of a spring 9 that surrounds said bar, as shown in Fig. 4.

A headed bushing-17 surrounding a portion of the pin 26 is threaded into the ear 7 of the punch bar and extends outwardly through a slot 19 in the upper end of the carrier 14, and surrounding the extended portion of said bushing is the hub 31 of a- .and said punch may consist of a single hollow punch tube or of a plurality of hollow punch tubes, as shown in Fig. 4, depending upon the style of perforations which are to be formed in the stock, the pieces of punchedout material. passing up through an opening in the punch bar and out of a chute 36 fastened to the carrier 14.

, A presser foot 40 is conveniently secured, as by a screw 89, to a block 43 slidingly mounted in a bearing 45 on the lower end of a. presser foot bar 41-2 which is mounted in the central longitudinal plane of the machine and which isconnected at its upper end to an elbow lever 44 pivoted to a stationary part of the frame and provided with a roller 16 that is engaged by a cam 48 on the main shaft for moving the presser foot bar up.

wardly, the presser f0 t bar being moved downwardly by a coi ed spring 47 which surrounds said bar between a shoulder there on and a stationary part of the frame, as shown in dotted lines in Fig. 1. As shown in Fig. 1, the presser foot is adapted to engage the stock at a point directly in the path in which the punch moves laterally for feeding the stock, so that when the stock is turned about the presser foot to produce a curved or irregular line of perforations the point at which the last perforation was made will be moved at approximately a right angle to the direction in which the stock is being fed, the fulcrum about which the stock is turned being located in the same vertical plane as that in which the punch moves laterally. The presser foot is preferably provided with a contact face which is shaped to engage a small portion only of the stock at a point in alinement with the perforations being formed. The stock may thus be turned readily about the presser foot as a center and without liability of producing unequal spacing between the perforations. The block 43 which carries the presser foot is connected by a pin 11 to the end of an actuating lever 50 mounted in the presser foot bar, which may be slotted to receive it, and pivotally connected at 51 to a sleeve 52 on said bar, the movement of said block in its bearing being ing plate 77 being fastened to said stud. The strip passes under a guide roller 78 mounted on a stud 7 9 carried by the standard, through a guideway formed by a Hat tube 80 mounted on the frame of thema chine below the table, over a guide roller 82 mounted at the end of said tube and thence in the opposite direction through a tube 83 extending parallel to tube 80. From the tube 83 the strip passes up through a slot 81 formed in the table, over the punch block 3, and then below the surface of the table through a slot '85 to a guide roller 84 mounted on the stud 79, and from said roller up to a receiving spool 86 which is fastened to a shaft 88 carried by the standard 76. The receiving spool 86 is ,rovided with a slot 87 in which the end 0 the strip is inserted, said strip being confined between the retaining plate 89 and cooperating plate 97 pro vided with a socket 98 which receives the split end of shaft 88, as shown in Fig. 9.

-A pulley 90 is loosely mounted on shaft 88-and is driven by means ofa belt 91 that passes over a pulley 92 on the main shaft, the pulley 90 being confined between two friction washers 93 and 94 splined to the shaft 88. A coiled spring 95 surrounds the shaft 88 between washer 94 and a nut 96 on said shaft and operates to force said friction washers and pulley into engagement with each other for causing rotary movement to be imparted to said shaft. The tension of spring 95 can be varied by adjusting the nut 96 and in practice the tension of said spring is so regulated that it W111 cause rotary movement to be'impar ted to shaft 88 only when the punch is feeding the stock and the strip, thereby taking up the slack in the strip.v After the strip has passed through themachine once and has been wound into a coil on the jSpOOl 86, the coil is removed from said spool and is again placed on the stud 33, the coil beingreversed so that the opposite edge of the strip will-be acted upon by the punch when it is again fed through the machine.

In order that the strip 7 2 may be used .a number of times, the guideway formed by the tubes 80 and 83 is adapted to beadjustr ed transversely of the punch blockso that different portions of the width of the strip can be brought into position to be acted upon by the punch, said tubes being fastened to a block 99 which is engagedby the'threaded end of an adjusting screw 177 rotatably mounted in upwardly projecting lugs 37, 37' on the base of the machine.

The operation of the machine is as follows: As the main shaft revolves, the cam 6 forces thepunch through the stock and into the stri of flexible material which is in'terosed etween the strip andthe punch lock.- Thereafter. the punch retracted slightly but is not withdrawn from the stock or strip, and the cams l0 and 12 op erating upon the lever 18 swing the punch carrier laterally in the direction of the arrow in Fig. 4 for causing the punch to feed the stock and also the strip of flexible material, said stripl being wound onto the spool 86 asit is fe step by step with the stock. When the punch arrives at the end of its lateral movement, the-presser foot bar moves downwardly and the spring 58 moves the presser foot 40 into position to engage the stock at a point in alinement with the line of perforations being formed in the stock,

the presser foot remaining in engagement with the stock while the punch is being withdrawn from the stock and strip by the spring 9 surrounding the punch bar, and moved back to starting position by the spring 11 acting upon the punch bar carrier.

As the punch is again forced into the stock the cam 48, operating on lever 44, moves the presser foot bar upwardly and during the upward movement of the presser'foot bar the toe 54 on lever 50 comes into engagement with the stop 56, thereby rocking said lever and moving the presser foot in the direction of the arrow in Fig. 6 out of-the path of lateral movement of the punch. These operations are repeated forforming successive perforations in the stock, and so long as the stock is not turned about the resser foot the perforations will be forme ina straight line. By turning the stock about i I the presser foot as a fulcrum, the point'a-t which the last perforationwas made will bemoved at approximately a right angle to the direction in which the stock is bein fed and a different portion of the stock wilfbe moved into alinement with the punch, so that the next perforation which is formed will be out of alinement with those formed in a straight line, the operator continuing to turn the stock after each-feed movement so as to form a curved or'irregular line of perforations.
