PERFORATING lvIAOHINE.
Application filed November 18, 1919.
To (ZZZ "LU/Q0921. it may I concern Be it known that I, LoUIsJ. VAN GUEL- PEN, a citizen of the United States, residing the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Perforating Machines, of which'the followin is a specification. v
The object'of my invention is to produce a compact and highly eflicient machine for perforating shoe tips, Vamps, foxings, sweat bands in hats, parts of gloves, and any other part or parts of shoes, boots and the like, or any other parts of any article of manufacture, or the article itself, and the machine can be used to place these perforations in leather, cloth, rubber, canvas, paper, or any other flexible material.
This machine is preferably used to form a continuous line of perforations, evenly spaced, but may be made to form perforations with wider spaces between them, and nay be adjusted to allow wider or narrower spaces between such perforations, as may be required.
One of the salient features of my invention enables me to perforate flat work, on a flat plate or support and also enables me to perforate this flat work, after it has been sewed up and closed, in the shape of a ring, amiulus, oval or any other irregular or peculiar form and this I accomplish on a cylinder or cylindrical arm.
' In punching or perforating under the systom now in vogue, the paper which is used under the material while the perforating is taking place, (and which paper is used as a cushion or the like), runs, or is fed in the same direction as the material, and in align ment with the perforations; whereas in my machine the paper is fed and moves at right angles to the material being punched or perforated.
In the accompanying drawing, forming part of this specification:
Fig. 1, is a longitudinal section of the main supporting arm of the machine, the operative parts being in elevation the rounded arm being also in elevation,
Fig. 2, is a front elevation of my machine,
Fig. 3, is a sectional view on the line 33 of Fig. 1,
Fig. 4, is a sectional view on the line 44 of Fig. 1,
Fig. 5, is a sectional view on the line 55 of Fig. 1,
Serial No. 338,956.
Fig. 6, is a sectional view on the line 33 of Fig. 1, the section showing only through the rounded arm,
Fig. 7, is a sectional view of the lower part of the punch bar,
Fig. 8, is a view in elevation of the or cushion feed mechanism,
Fig. 9, is an elevation partly in section of the punch feed mechanism, on line 9-9 of Fig. 4,

Fig. 20, is a view of the arm in elevation (or a side view), and part of the machine broken away, the arm also partly broken away to show construction.
I provide a hollow arm, formed of a base part 1, an upright part2 and a forwardly extending part 3; the arm being connected to a, table or bench through medium of base part 1.
In the part 2 of the arm, I journal a drive or cam shaft 4, carrying on the outside a drive pulley 5 and a hand wheel 6, made integral. In the part 3 of the arm, I journal a rock shaft 7 Between the shaft 4 and shaft 7, I place, in part 2 of the arm, a stud 8, (see particularly Fig. 1). In part 2 of the arm, on the drive shaft 4, I rigidly attach two cams 9 and 10. The cam 9 (see particularly Fig. 5) is so shaped that two of its parts or surfaces will always be in contact with the fork arms 11. The cam 10 (see particularly Fig. 4), is the same in paper shape and size as cam 9 and two of its surfaces or parts are always in contact with the ways 12 of housing 13. At the inner end of drive or cam shaft 4, I rigidly attach a spiral gear 14, meshing with a spiral gear 15, on short shaft 16 (see particularly Figs. 1 and 6). On the stud 8, I loosely attach a lever 17, and at the upper part, said lever carries a segment gear 18 which meshes with a segment gear 19, which is adjustably attached to the rock shaft 7. The lower part of the lever 17 carries a forked or bifurcated 'end, the arms of which end are markedll.
The cam or drive shaft 4 passes. through an-elo'ngated slot in the housing 13, an up and down motion being given to the housing 13, as the cam 10 is passing and revolving and comingin contact with the ways 12, the slot 20 preventing a lateral motion thereto. At the top of housing 13, I provide a stem 21 which is loosely connected by stud 22 to one end of an arm 23, the otherend of the arm is fulcrumed at 24 by a stud at tached t0 the frame part 2 of the arm; the said arm at this end carrying a segment 25 provided with a segmental slot 26; the arm 23 and the segment 25 being made integral. A slide block 27 works loosely in the slot 26 and is connected by a stud 28 to an arm29, which arm is connected loosely at its inner end to a lever 30 by a stud 31. The lever 30 is adjustably attached to a sleeve 32 which works loosely on shaft 7. On the forward end of sleeve 32, is a downwardly and forwardly extending arm 32 made integral therewith. At the outer end of the arm 29, I provide an adjusting pin 33, which at its inner end carries a finger 34 which is placed on pin 32, out of center thereon. The segment 25 carries a multiplicity of staggered holes 35, into which the finger 34 enters and registers by'manual operation. Aslot 36 is provided in part 2 of. the arm to accommodate part of the mechanism set forth.
The aboi e mechanism just described has to do with the movement of the punch laterally or sidewise, and will be more fully horizontal slide shaft 40-40. A U-shaped piece 41, extending upwardly from the lower bearing 38 carries a slide block 42, said slide block being loosely connected by a stud 43, rigidly connected in the end of the arm 32 and, as the sleeve 32 and arm 32 oscillate, the housing just described moves forward and backward.
I will now refer to the mechanism for operating the punch bar up and down. At
the forward end of the rock shaft 7, I con- 'nect a crank 44; at the lower end of this crank I connect a stud 45 which carries a slide block 46, said block working in a slot 47 in the punch bar holder 48; said punch bar holder being adjustably connected to the punch bar 49, by means of the said punch bar being screw threaded into the punch bar holder 48. Near the'center or the middle of the horizontal bearings .37 and 38, and extending forwardly therefrom, I provi de two vertical bearings 50-50, said bearings keep the punch bar in alignment and support the same so that it can properly move up and. down, acting like sleeves for the punch bar;
Thepunch 'bar 49, at its lower extremity carries a cutting tube holder 51, inserted into the bottom vo f said punch bar and is provided with a flange or collar 52, threaded on its periphery to receive thethreaded collar 53 which rests on a shoulder 54 on the punch bar, and thus the tube holder is held in the punch bar 49. At the bottom of the punch holder, I place the cutting tube or tubes 55; the cutting tube is hollow and the punch holder has a hole 56, aligned with the hole I provide an arm 59, formed like a bracket, which'is cast integral with the part 2 of the upwardly extending arm. This arm or bracket forms the punching anvil at point 60, and supports the feeding plate and the paper feed mechanism.
The feed plate is marked 61 and is formed as shown in Fig. 10, having a locking yoke 62 by means of which it is attached to the arm 59 bya screw .63; it can thus be removed at will without changing or readjusting any of the mechanism. On this feed plate I support flat work, as shown in Figs. 11, 14, 16 and 17, and this plate is removed when I doclosed worlgshown in Figs. 12, 13 and 15.
I will now describe the two paper feeding rolls64 and 65, both ofwhich have a roughened o-r knurled. face; the roller 64 is inside the arm59 and is'loosely supported on a bearing 66 on a stud 70, said bearingextending from one of the side walls 67 of-the arm 59; the roller 65 is below the arm and is supported in a bearing 68 on a'shaf-t7l and rigidly attached thereto. The bearing68 is attached to a bracket 69, on the lower part of arm 59, (see particularlyFigs. 1, 2 and 3). The extending shaft 71 o f'the roller 65 carries at its outer end a ratchet wheel 72' and also an arm 73, at the upper end of which I placea ratchet pawl 74 which operates and revolves the ratchet wheel 72; at the lowerend ofarm 73 I loosely attach a link or connecting bar 75 which at its opp osite end is loosely attached to a lever or crank 76; said crank being rigidly attached. to shaft 16.
On the shaft 71, I adjustably attach a guide 77, having a flange 78 projecting over said ratchet wheel 72, on which flange the pawl 74 rides; andafter riding over the face of said flange engages one of the teeth of said ratchet wheel; being adjustably attached by moving said guide and its flange or less extent by the paper feed rolls 64 and 65. This paper may be guided and held in alignment by any suitable means (not shown). At the forward end of the arm 59, I place two rolls and 81, over which the paper passes. The paper 79 is held on a spool or reel (not shown), and from this point travels up through slots 82 and 83, in the arm 59, and thence over the top of the arm 59, under the punch bar 49, and then over the rolls 80 and 81 back through the paper feed wheels 64 and 65. I will now describe a guide for the material to be worked upon. Underneath part 3 of the arm, I provide a lug 84 and in this lug I connect a small shaft 85, which carries a downwardly and forwardly extending arm 86, adjustably attached to shaft 85, and at its end, said arm carries a pcculiarly shaped foot 87, adj ustalbly attached; said foot 87 carries asmall spring 88 at its forward end to keep the material from turning or buckling up at its edge. This spring also acts as a stripper as the punch tube 55 recedes from the leather or material worked upon.
In Fig. 11, I show a long vamp 89, open and not sewed, having, perforations 90 around its inner edge. The operator must use his or her own judgment as to where the stitching will be located, from the edge 91, and, if the perforations come too close to said edge 91, when the vamp is closed, the staying stitching 92 (see Figs. 12 and 13) may, by chance, pass through some of the perforations and thus make a defective shoe. In Fig. 12, the vamp 89, has perforations 90 and is the vamp shown in Fig. 11, except that it has been closed and stayed, the staying stitches being marked 92. When the vamp is in this condition, the operator can make no mistake, as she can readily observe the staying stitches and thus perforate accordingly; and this closed vamp can be perforated on my machine, as will be hereinafter described.
In Fig. 14, I show a vamp 93 having foxing 94, having perforations 90, and in Fig. 15, I show the vamp closed and stayed by stitching 95 and 96. If the operator must perforate the vamp and foXing separately, as shown in Fig. 14, then said operator must guess where to begin perforating at the edges97 and 98, and the stitching 95 or 96 may pass intosome of the perforations in both places, or in either place, thus producing a defective shoe.
. By using my machine the. operator can see where to begin and stop, the same as in perforating the vamp shown in Fig. 12.
The vamp99, shown in Fig. '16, is known as a circular vamp and cannot be sewed together before perforating, because it must be done flat or spread out.
In Fig. 17 I show a shoe tip 100, which must be perforated fiat before being sewed to the shoe vamp.
The feed plate 61 has a slot 101, (see Fig. 10). At the top of the arm 59, which top part of said arm is fiat, and atthe outer edges of said arm, I form recesses 102, (see Figs. 2 and3), which are as deep as the thickness of the plate at this point, so that when the plate 61 is slipped into these re cesses, it will lie flush with the top of the arm. andthus form a continuous flat surface, after the screw 63 has been set and tightened on the bottom of arm 59. When flat work is to be done on this machine, for the convenience of the operator, and to secure results, this plate 61 is used; but, when closed work and the like is to be done, some forms of which are shown in Figs. 12, 13, and 15, the feed plate 61 is removed and the work is done on the arm 59, inasmuch as this arm is cylindrical and rounded, (see particularly Figs. 18, 19, and 20) and such work can be placed or hung on the arm as shown in Fig. 19, where the vamp marked 89, is shown in position. In operating the machine motion is transmitted to shaft 4 through pulley 5, which shaft revolves and thus turns cam 9, this in turn moves lever 17, which oscillates the segment gears 18 and 19, and the gear 19 being adjustably attached to rock shaft 7, and thus this shaft is rocked or oscillated. At forward end of this shaft 7 is connected the crank 44, which being operated by the said shaft 7, in turn, with its connections to the punch bar holder 48; which is adjustably connected to punch bar 49, reciprocates the punch bar holder 48, consequently the punch bar 49 and the punch tube 55 are also reciprocated.
Therevolving shaft 4 also revolves cam 10, which in turn reciprocates the housing 21, the lever 23 and the segmental slide way 25, the lever 29 being attached thereto is reciprocated horizontally, and, being attached to lever 30, which in turn is adjustably attached to sleeve 32, on rock shaft 7, oscillates the said sleeve 32. At the forward end of the lever 32 is a lever 32- attached to a slide on the punch bar housing, said punch bar housing being loosely attached on shafts 4040, 'which in turn move thepunch bar housing laterally.
The stock to be Worked upon is placed; underthe punch and against the guide part '87 and under the spring 88; the machine is then started, (the paper cushion 79"be'ing always fed at right angles or differentdi rection, and under the material oristock, at all times) the punch descends through the material and partly into the paper'cus'hion 79; the punch then recedes and pulls: out of the paper cushion until the lower cutting face of the cutting tube is flush with the top face of said paper cushion thenfthe punch moves laterally, carrying the material along with it, to the point indicated by'the spacing mechanism heretofore set forth; "atwhich point the stock holding means (not shown), any form of which maybe emof arm 59, where it is used as an anvil (part (39); the punch then receding out of the material to its highest position; then the punch moves forward and is ready for another dcscentto punch the next perforation; and continuing to reproduce this action un til the stock is needed.
This machine is power operated and the power can be stopped at any time desired. If it is desired to operate themachine to any position, the operator can do it by hand through the medium of the handwheel 6.
Some attempts have been made to perforate a stayed .vamp, or similar article of manufacture on a perforating mach1ne,but
such attempts have been mechanically and commercially unsatisfactory; however, on my machine, on account of'its peculiar construction, such work can be mechanically and commercially, successfully accomplished.
Although I have described one formof my machine specifically in this application,
perforated as desired '01-,
I wish to be understood'as claiming any modified form thereof.
