Application filed September 25, 1920. Serial K; 412,667.

To all whom it may concern:

Be it known that we, THOMAS C. lfTEw- MAN and THEARON A. RICHARDS, citizens of the United States, residing at Rochester,

in the county of Monroe and State of New York, have invented certain Improvements in Vamp-Perforating Machines, of wh ch the following description, in connection with the accompanyingdrawings, is a speck 'fication, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for operating upon sheet material and for purposes of illustration is disclosed herein as embodied in a vamp perforating machine, this application being a continuation in part of our co-pending application Serial No. 295,349, filed May 7, 1919.-

In the manufacture of boots and shoes, it is usual to ornament certain parts of the upper by punching designs therein by means of a gang punching machine. When it is desired so to use a pattern punch to ornament some of these. parts, asthe toe portion of a vamp or wing tip, difiiculty isexperienced in presenting the work to.

the machine in the proper symmetrical manner, especially since in machines commonly used for this work it is impossible to see that part of the stock to be operated upon after it has been placed in position to be punched.

For purposes of of properly presenting a vamp to receive an ornamental punched pattern in its toe rtion 'will be considered in some detail, though it istobe understood that the invention is in no way limited in its applicability to the punching of Vamps. The toe portions of Vamps are not SYIII'. metrically cut onregular curves, and their outlines differ according as they are rights or lefts and according to their size. It frequently happens that there are used ina dred. different forms, the difierences being illustration, the problemsingle factory camps havingseveral hun-.

longitudinal position of the pattern to be punched varies, being given as a distance from the center of the throat of the vamp, and this renders still less feasible the use of edge gages contacting with the toe portions of the vamps.

An object of the present invention, ac

cordingly, is to provide asatisfactory gage for positioning Vamps to be operated 'upon and so constructed that its use shall be free from these and other difliculties, and so that it shall be capable of satisfactory use by unskilled or unintelligent operatives. to present the work to the operating parts of the machine with such speed. and certainty as will result in a large output of acceptable pieces'of work with the perforating accurately placed. With this object in View a feature of the invention comprises a gage arranged to engage the throats of Vamps to be perforated or otherwise orna-' mented and provided with novel adjusting means whereby the gage may be adjusted in two directions simultaneously so as to fit the throats of vamps of different sizes.

'Preferably the location of the gages with respect to the perforating .or other ornamenting means in accordance with the sizesof the Vamps is varied .at the same time. As

illustrated the gage consists ofa pair ofmembers constructed to engage the throats of Vamps and arranged for simultaneous adjustment in a pre etermined ratio longitudinally of a vamp support and in opposite directions transversely thereof, the ratio of the adjustments being such that as the gage members are moved longitudinally' a distance equal to the difference in the desired distance of the perforation from the throat of the vampin two different sizes, their position transversely will be simultaneously varied just enough to con1- pensate for the difference in the widths of the throat-sot the two Vamps. A scale may be provided on a suitable part of the machine, numbered to correspond to a suitable range of sizes and in 00-0 erative relation to an index, the scale an index being .so related that as the gage is adjusted the relative positions of the index and scale indicate the size of vamp corresponding to the adjustment of the gage. Thus the operative may easily adjust the gage with pre- 1. c1s1on 1n accordance W1th the size of vam to be perforated.

. ture of the invention consists of means for varying the ratio of the longitudinal to the transverse movement of the gage members. In the illustrated embodiment of the invention a scale and indicator are provided in order thatthe operative may conveniently reproduce the desired ratio'between these two movements; 7

When a vamp is to be provided with a line of perforations such as is known as an imitation tip, orwitha medallion, it is frequently considered desirable to angle the perforation, that is, to position it with the portion thereof on the outer side. of the shoe slightly rearward of the portion on the inner side. A feature of the invention, ac cordingly, consists of means whereby the relative position of the gage and a gang punch by which the vamp is to be perforated may. e adjusted angularly about an axis perpendicular to the plane of the vamp and die detached from the through the small angle necessary to accomplish this pur ose.

With these an other objects ,in view, the invention will now be described in connection with ,the accompanying drawings and pointed out in the claims.

The invention is applicable to the usual forms of punch presses and is shown in the present instance 1n conjunction with apress having a frame 25 carrying a main shaft 26 driven by'means of a pulley 27 and operating a ram 28, the'latter being provided with a socket 29 and a set screw 30 for'securinga die block to the ram. The present embodiment comprises. preferably, a die block or support 31 having a shank 32 (Fig. 9) and pivotally'secured to the lower face of the block by means of a stud 33 (Fig. 10) is a die holder 34. The under face vof the latter carries at its end undercut guides 35 which together form a wide dovetail groove or guide for receiving the correspondingly shaped die having an upper portion 36. Spaced, preferably, from the portion 36, by means of members 36, is a plate 37 forming the face of the die from which projects a series of cutting or punchingtools 38 arranged according to the design which it is desired .to' cut in the toe portion of the vamp.

justably connected-to the die block for the purposes explained hereafter, the die holder being pivoted on the central stud 33, which movement is limited in either direction by.

the die holder by screws 42 on the rear of, the

latter, each having a head overlapping the portion 36 and by a clip 43 engaging the forward side of the die portion 36 and secured by means of a screw to the die holder.

The cutting tools 38 are preferably hollow punches, as indicated at 44, Fig. 17 extend- The die holder and die are together ading through plate 37, for the escape of, the cuttingsand are disposed on the die to form the desired design, such as an imitation tip or medallion with which the vamp is to be ornamented. One style of die is shown in Fig.15as having a line 45 of such punches, interrupted at its center. The cutting tools are preferably provided with a stripping plate of any suitable form such as that indicated at 48 (Figs. 15, 16 and 18 yieldably' secured to the die as by means of a loose bearing on screws 49 fixed in the plate and interposed compression springs 50 on the screws. If it is desired to mark orscore the vamp to serve as a adjacent to the perforations, orfor other purposes, the stripper plate is preferably provided with pro ections 51 adapted to score the vamp, the resilient means supporting the stripper being sufiiciently stifi' to produce this eiiect-as the stripper yields to permit the tools to project therethrough and cut the vamp. "In Fig. 11 is shown a somewhat difi'erent style of die.

In the style of punching machine herein shown, the support for the vamp is fixed on the bed 53 of the press by means of bolts 54, Fig. 2, and as shown comprises a plate 55 havin an upper surface 56 of material suitable or co-operation with the cutting tools without injury to the latter. The support 55 functions herein both as a vamp esupport and as a platen and has a reduced extension 57 carrying the vamp gage.

The gage comprises, as illustrated, a pair.

of plates 58 which, in the present instance, are rounded at their front ends and curved rearwardly at the sides where they engage the side edges of the vamp throat. These plates are designed to fit the throat of a v'amp such, for example, as that indicated in broken lines at 59 in Fig. 3. They may, however, have any form determined by the style of vamp with which they are to be used. The plates are detachably secured, as by means of pins 60, to plates 61, respectively, these plates 61 being adapted to slide longitudinally or toward and from the die, in guideways in plates 62. J To guide the plates 61 longitudinally in plates 62 and yet-cause them to move transversely with the latter, there are provided guide slots 63 in the plates 61' engaged by screws 64 secured to the plates 62. To the bottom of each of the latter is fixed a lug 65 having a reduced upperportion 66 slidably fitting in a slot 67 extending transversely of plate 57, the lugsbeing secured to the plates by means of screws 68. Fixed to,- the center of plate 57 by means of a screw 69, in line with and between the lugs 65, is a stationary lug 70 having a transverse bore71 in which is rotatably carried a spindle 7 2 ormed with a recess to prevent endwise movement of the spindle in the lug. The spindle is ide for stitching provided towards'its respectieve ends withv its finger-pieces 76, serves to move lugs 65 toward or from each other in the slots 67 according to the direction in which the spindle is rotated. The lugs, of course, move thaplates 62 secured thereto as well as the plates 61 and the gage plates 58 in the same manner, toward 'or from each other transversely of the'gage, to contract or expand the gage, to fit the difl'erent Vamps.

To accommodate Vamps of different sizes, means is provided for adjusting the gage plates longitudinally of the vamp comprising, as illustrated, a pair of bell crank levers 77 (Figs. 5 and 7 fulcrumed at 78 to the under side of plate 57, each lever having a slotted arm 79 connected adjustably to the corresponding lug 65 and having also a slotted arm 80 engaging a pin 81 depending from the corresponding plate 61. Slots 82 are provided in the plates 62 to enable the pins 81 to move longitudinally when the plates 61 slide in their guideways in plates 62 and a pair of circular openings '83 are formed in plate 57 to enable the pins 81 and the plates 61 and 62' to have .both transverse and longitudinal movement. The slotted arms 79 engage pins 84 rising from angular blocks 85 screwed to threaded guide pins 87 which slide in guide holes88 in the lugs 65. The position of the pins 84 in the slots of the arms 7 9 determines the, ratio of the longitudinal and transverse movements of the gage plates and this ratio may be changed as desired to suit the different systems of size measurement or variations in grade. The blocks 85 carrying the pins 84 are forked as indicated at 86, and, extending into these forks, are the slotted ends 94 of a bar 93 which can be adjusted by means of a screw rod 89. The screw rod 89 has a finger piece 90 at one end and at the other end is secured rotatably to the block 70 by a'collar 92. The rod is threaded into the bar 93 so that rotation of the rod moves the bar and the angular the position of these pins 84in the slotted arms 79. A look nut- 95 may be used to fix the adjustment. It is evident that as the lugsf65 are adjusted outwardly, the plates 62 and 61 will be carried transversely, the reduced portions 66 of the lugs 65 movingin the slots 67 of the plate. 57 Simultan'eously, the angular blocks 85 and pins 84 are carried transversely and rotate the bell crank levers 77 on their pivots. results in a longitudinal. movement of the pins 81 in the slots 82 and causes the plates 61 to slide longitudinally in the guideways of the plates 62. The ratio of blocks 85 to vary This justment forvamps of the .usual seriesof' sizes.

The operation of the device requires but a brief explanation in connection with the' description of "its construction. The rotatlon of spindle 72 is operative, through lugs I 65, to adjust the two gage members 58 in opposite directions transversely of the machine, and the motion of lugs is transmitted by levers 77 and pins 81'to move the two gage members 58 longitudinally both in the longitu same direction, the longitudinal and transverse adjustment beingin a predetermined ratio to accommodate and correctly to posi- 7 tion different sizes of vamps. The gage hav- 7 ing been adjusted for the size of the vamp to be operated upon, the die may be shifted slightly on the die block as described, accordingly as the vamp is a right or a left, to move the punches which are to perforate the vam towards its outer edge, rearwardly ally of the latter, and the tools on the other edge in the opposite direction where it is desired to angle the perfprating to provide a compensation for the dlfierence in adjustment of right and left vamps to the shoe, as well understood in the art.

The press is then operated 'in the manner, usual with machines of this gtype,causing the die to descend and perforate the vamp, the marking projections of the stripper plate, if such are used, scoring the. vamp to indicate the pro r lines for stitching, where the latter is to E: e ployed.

The machine is s mph and eflicient in construction, being adapted for ap lication economically to usual forms of punc presses and is especially advantageous in that'it may combine in one machine for simultaneous operatlon, mechanism for grading or sltioning the'vamp, markin the latter, and
