J. EDWARDS IIECOIZPORATED, 9F BOSTON, MASSACHUSETTS, A. CORPORATION OF MASSACHUSETTS MARKING DEVICE FOR REGULAR Gli-ADED SHOE UPPER, BLANKS Application filed February 9, 1931. Serial No. 514,366.

The present invention relates to marking devices which are used in the manufacture of shoes to mark upper blanks, such as Vamps, tips, quarters, foxings and straps, with lines for use as guides in subsequent hand and machine operations. The guide lines may indicate the center lines of the blanks, the lap of one blank over an adjacent blank, or the location of overlays, underlays, perfora- 10 tions, embossings, ornamentalcut-outs and stitches.

The marking device disclosed in my Patent No. 1,7 53,88t, April 8, 1930, known as the Edwards stitch marker, was introduced to the shoe industry in the second quarter of 1925 with the belief that it would obviate the troubles shoe manufacturers had experienced for years in marking upper blanks by hand through the medium of the stencils described in said patent. Immediately upon its introduction the Edwards stitch marker was adopted as standard'shoe factory equipment by those shoe manufacturers employing center graded upper blanks. While the Edwards stitch marker is an extremely important factor in the art of marking center graded upper blanks it has never been able to make any lasting impression in the art of marking regular graded shoe upper blanks.

Upper blanks in a series of the different sizes (which term is usedherein to include half-sizes) and the different widths of the same style which have a common portion of their peripheries held to the same grade, are called center graded. Notwithstanding the variations in sizes and widths, a series of center graded upper blanks of the same style may be marked in the Edwards stitch marker employing a single gage which registers with the common portion in the peripheries of the blanks throughout the series.

Regular graded upper blanks have no common portion in their peripheries and there- 9 about five dilferent widths, on an average,

fore a difierent gage for each size in each in a series of regular graded vampsof the same style it follows that seventy-five different gages for rights and seventy-five diffcrent gages for lefts must be manufactured in order to mark such a series of regular graded upper blanks in the Edwards stitch marker. This large number of separate gages is the principal reason why shoe manufacturers of regular graded shoes have found it impracticable to supplant the stencil method of hand marking with the Edwards stitch marker.

The principal object of the present invention is to produce a marking device by which regular graded shoe upper blanks may be marked in a rapid, reliable and economical manner.

or in my Patent No. 1,796,686, March 17,

1931, or in the reissued patent to Woodwort-h, 17,715, June 24, 1930, each gage being located in spaced relation on an extensive surface positioned on the marking device and shiftable beneath the marking member thereof to correlate at least one of the gages therewith. Bearing in mind that substantially one hundred and fifty separate gages are required to mark an average range of sizes in the average run of widths in a series of regular graded upper blanks of the same style, including rights and lefts, itis apparent that the surface would be rather long for convenient handling in the marking device. Even if the extensive surface was articulated be tween the gages its bulk would present difli-V culti-es. Therefore, I prefer to mount the separate gages on a sheet in the form of-line contours corresponding to certain contours of at least one complete range of sizes and Widths of ti e same style in a series of right and left regular graded shoe upper blanks and to mount the sheet in a marking device so that at least one thereon may be se lectiv-ely correlated with the marking member. Such a sheet may contain an enormous number-of gages without interfering with its capability of being Wound on a roll. which may be stored. with, other rolls other. setsof'different in a readily accessible position when not in use anrl'wliich may be readilyinser-table into and-removable from the marking cevice.

Other features of the invention relate. to certain devices, combinations and arrange mentsof parts hereinaft then set forth broadly and in detail in'tlie appendedi claims which possess advantages which will'be apparent to those skilled in th art. 1

The variousfeatures of the present invention Will be'readily understoodfrom an inspection oftheaccompanying drawings illustrating the best form of the invention at presentknown to the inventor, in which Figure 1 is a view inplan of a-inarking device for marking regular graded shoe up per blanks;

Referring first to Fig. 8 it illustrates 'a 2 B vamp 11, a 5-13 vamp 12 and a 9B vamp 13, allcenter graded, superimposed for the purpose of demonstrating that they have a common portion extending along the throats l t-between the point 15 and the point- 16. Thus, agage provided with either of containing.

described and hereinbefore referred to, shaped to register with the said common portion, will correlate the Vamps 11, 12 and 18 singly with the marking members disclosed in said patents, respectively. As the Vamps 11, 12 and 13 form only a few of the Vamps in a series of the usual run of sizes and of widths of'the same style the gage for engaging uniformly the common portion of the three Vamps 11,12 andldmay, and ordinarily does, engage the similar common portion in all the other vampsin the same series.

Fig. 7 illustrates a 2 -B vamp 17, a 5-B vamp18,.and a 9-:B vamp 19, all regular graded, superimposed for the purpose of demonstrating that they have no common portionthat'can be engaged-by a single gage. Iii-consequence, inorder to mark," in the pres-- ent commercialEdwards-stitch marker, a seriesof regular graded Vamps comprising about fifteen sizes running'from two to nine in aboutfive different widths and including rights and lofts, onehundred and fifty different gages would be required;

In :order: to. mark: a series of regular graded shoe'upperblanks, such asvamps, of atleast one complete range ofsizes of one width and style, the throat and wingcontours'26 l igs. 1 and 4) of the-different patterns for the Vamps are transferred toxa longsheet 27. As sh Wn-in Figs; 1 and l thesheet 2?. is provided with the regular graded throat and wing contours 26 of a set ofpatterns running from 2 -.B to 9,-B. of the same Width; and style,- atotaloffourteen contours. Stated in another way, thes-heet 27 comprisesa set of gages 26 each gage in the set having a contourshaped'to register with a-contour; on an upper blank of a definite, size,--width and style. The sheet 27 may be providedswitha plurality ofnset-s of gages so'that it may be employed:in marlring a number'of the dif ferent sized regular graded'vamps inthe different widths of the same: style. As indi+ cated inFigs. 1% and-41 thesheetl 27 is'provided-with one set of gages for gaging right vamps-intherun of sizes in the B- width of the Ednastyle andanother set of gages for gaging left vampsin the same runof sizes. width'and style.

@ne end of'the sheet :27 is anchoredto the peripheral surface'of a: hollow cylindrical spool or'roll'28- (Figs. 2, l and 5) provided with end fiangesQQand 3.0. Adjacent the flange 29 the spool 28is providedwith aslotv El (Fig. 5) w-hichengages a lugSQprojectthe Walls disclosed in my two patents, both ingqfi'om the peripheral surface of a cylindrical rod 33. One end of the rod 33 is provided with an internal head 34 secured rigidly thereto which has a cylindrical projection 35 mounted to rotate in the bottom of an open slot 36 formed in a bracket 37. As shown in Fig. 1 the bracket 37 is secured to one rear corner of the bed plate 38 of the marking device disclosed in my Patent No. 1,796,686 hereinbefore referred to.

The other end of the rod 33 is provided with an internal head 39 loosely mounted to rotate within the rod but held from movement longitudinally thereof by a small rod 40 one end of which is secured to the head 39 and the other end of which is mounted to rotate in a step bearing 41 formed on the inside face of the head 34. The internal head 39 is provided with a rectangular projection 42 which is held from rotation in a slot 43 formed in a bracket 44 secured to the other rear corner of the bed plate 38.

With this construction the rod 33 and the spool 28 may be removed bodily from the brackets 37 and 44, the spool 28 removed from the rod 33 and another spool 28, provided with a different sheet 27 containing a different set or different sets of gages 26 positioned on the rod 33 which is then reinserted in the brackets 37 and 44. Thus, in effect, the rod 33 constitutes a permanent part of the marking device, while the rolls 28 and the sheets 27 wound thereon constitute interchangeable units which may be stored, when not in use, in labelled boxes.

The free end of the sheet 27 is provided with an eyelet (Fig. 2) which, after the sheet has been conducted under a small roll 46 (Figs. 1, 2 and 4) supported from the brackets 37 and 44, and over the upper surface of the bed plate 38, is hooked on a hook 47 carried by a slabbed face 48 formed centrally on a cylindrical roll 49. The opposite ends of the roll 49 are provided with flanges 50 and 51 which rotate in engagement with the in- 5 side flanges of brackets 52 and 53, respectively, secured to the bed plate 38 on opposite sides of the sheet 27. The opposite ends of the roll 49 are provided with cylindrical rods 54 (Fig. 6) and 55( Fig. 4) journaled in the brackets 52 and 53, respectively. As shown in Fig. 2 the front end of the bed plate 38 may be formed as a trough 560 spaced from the periphery of the roll 49 to receive the sheet 27 when wound up thereon. The

rod 55 is bent to form a crank which is operated by the operative to rotate the roll 49 and thus wind a portion of the sheet thereon and at the same time withdraw another portion of the sheet from the spool 28 and position it on the bed plate 38. For this reason the roll 49 and the spool 28 are designated hereinafter as the receiving roll and the delivering roll, respectively.

In order to store power in the delivering roll when the crank 55 is rotated to wind a portion of the sheet 27 on the receiving roll so that the delivering roll may retract the sheet upon its release from the receiving roll, a spring 56 is coiled around the rod 40. One end of the spring 56 is secured to the head" 34 and the otherend of the spring 56 is connected to the head 39. As the head 34 rotates with the delivering roll and as the head 39 is held from rotation when the sheet 27 is withdrawn from the delivering roll by the rotation of the receiving roll, the spring 56 is tensioned and thus acts to retract the sheet 27 upon the release of its free end from the receiving roll.

As shown in. Fig. 1 the bed plate 38 is provided with two lines 57 located, respectively, on opposite sides of the sheet 27 The opposite sides of the sheet 27 are provided with a plurality of sets of lines 58' adapted to register with the lines 57, one'set at a time, to indicate the proper location of the front pert-ion of a certain sized vamp to receive the marks from the marking member to be described. As shown in Fig. 1 the lines 58 for a 6% size vamp are registered with the lines 57. Now if a 6 /2 regular graded vamp of the B width in the Edna'style is registered with the contour 26, on the sheet 27, labelled 6 the said vamp will be properly correlated with the marking member to receive the marks therefrom.

In order to hold the sheet 27 stationary with any one of the sets of lines 58 registered with the lines 57 the bracket 52 is provided ,4 with a set screw 59 having a wing 60 thereon to facilitate the engagement of the end of the screw with the rod 54', thus to lock the receiving roll in position against the tension of the spring 56.

In the illustrated embodiment of the in" vention the Vamps are marked with. a broken center line 61, a curved line 62 having its opposite ends reversely bent and two curved lines 63 and 64 having only one end reversely bent. The lines 62, 63 and 64 define between them an area to be perforated subsequently. The line 62 acts as a guide in the subsequent perforating operation. The perforated area is bordered with stitching and the lines 62 63 and 64 act as guides in .the subsequent"" stitching operation.

The lines 61, 62, 63 and 64 are formed by narrow faces 65 (Fig. 3) formed on the bottom of vertical flanges 66 (Fig. 2) project-. ing from a flat plate 67 secured to the bottom of a wooden block 68. The block 68 is interchangeable with other blocks carrying marking faces 65 having different configurations and is therefore detachably connected to a cross-head 69 and to an operating handle 70 substantially in the manner illustrated and described in the reissue patent to Woodworth hereinbefore referred to. 7

At its front end the cross-head 69 is jour-v naled in bearings carried, respectively, by

the upper ends of arms 71 and 72 (Fig. 1) projecting from the opposite ends of a horizontal rock-shaft 73 journaled in the frame 74 to which the bed plate 38 is secured. At its rear end the cross-head 69 is journaled in bearings carried, respectively, by the upper ends of arms 75 and 76 projecting from the opposite ends of a horizontal rock-shaft 7 7 journaled also in the bed 74. Intermediate their ends the arms 75 and 76 carry, respectively, pins 78 and 79 which project inwardly through the bed 74. To this end the bed 74 adjacent each of the pins 78 and 79 is provided with an arcuate slot 80. The pins 78 and 79 are connected, respectively, to the rear face of the frame 74 by coiled springs 81 and 82.

With this construction the springs 81 and 82 tend to hold the narrow marking faces 65 engaged with an ink pac 83. By engaging the handle 70 the operative may swing the narrow marking faces 65 from a position where they engage the ink pad 83 to a position where they mark the vamp registered with that gage 26 on the sheet 27 which is correlated with the marking member.

Referring to Figs. 1 and 2 it is apparent that if no sheet was positioned over the bed plate 38 the marking member, on its repeated downward movement, would engage the bed plate in an invariable position. This invariable position, for the purposes of description and definition, is termed a target. The sheet 27 covers this target, but the forward portion of each of the upper blanks gaged by the sheet must be positioned over the target in such a way that the marking member marks the upper blank in the prop er position depending on the grade for the particular size and width of the blank. The position of the lines 57 may be selected arbitrarily provided they are in a vertical plane intersecting some portion of the target. The spacing between the lines 58 may be also arbitrary. The particular spacing between the lines 58 in the illustrated embodiment of the invention is purely arbitrary, the spacing selected permitting the various contour lines 26 to be distinguished one from the other readily.

Any convenient method of providing the sheet 27 with the line contours 26 may be employed. In a set of patterns for a series of regular graded shoe upper blanks of the same width and style there is one which is cut through to indicate the location of the marks to be made on the blank. The lines 58, corresponding to the size of the cutthrough pattern, are then registered with the lines 57. Then the marking member is operated to mark the sheet. The slots in the cut-through pattern are superimposed upon the corresponding marks made upon the sheet and then the line 26 is drawn, using the throat and wings of the superimposed cutthrough pattern as guides. After one contour 26 is drawn upon the sheet all the others may be readily plotted as the variation in grade between the cut-through pattern and the next succeeding larger and smaller size in the series is a known factor. The line contours may be drawn in. ink but a pencil line is satisfactory as the various pencil lines may be protected by providing the sheet with a coating of suitable material.

It is expected confidently that the illustrated embodiment of the present invention will assist many shoe manufacturers now making only center graded shoes to adopt regular graded patterns when. it is to their advantage to do so on certain styles. As there are hundreds of Edwards stitch markers now in operation in center graded shoe factories, it is desirable that these marking devicesbe converted readily into devices for marking regular graded shoe upper blanks and be as readily reconverted into devices for marking center graded upper blanks.

To this end, the brackets 37, 44, 52 and 53, for the sheet delivering and receiving rolls, respectively, may be mounted on a brass plate 84 (Fig. 4) which is insertable upon and removable from the bed plate 38. The rear corners of the bed plate in the Edwards stitch marker are provided with vertical pins 85 and 86 5) for the removable gage used in gaging center graded upper blanks described in my Patent] No. 1,796,686 hereinbefo-re referred to. and 44 are provided with holes 87 and 88, respectively, which may be received by the pins 85 and 86. The plate 84 may bev described as a removable bed plate 38 as their functions in the marking operation are identical. Y

It will be readily understood by those skilled in the art that certain features of the illustrated embodiments of the present invention may beused. advantageously in the marking of center graded shoe upper blanks. For instance, in marking such blanks it is sometimes necessary to adjust the gage, which engages the common portion of the blanks, for each size to compensate'for a constant graduation in a portion of the blank other than the portion engaged by the gage from one size to the next succeeding size in the series. In such cases it would be much easier to employ a sheet 27, having thereon a plurality of identical. contours, which is shifted to correlate any selected one of the contours with the marking member and at the same time compensate for he graduation between the different sizes than to depend upon an adjustable 7 For the purpose of iisclosure I have illustrated the sheet 27 as being provided with a separate set of contours 26 for rights and a separate'set of contours for lefts. In certain cases, however, the contour 26 may be made The brackets 37.

in two colors, one for a right blank and the other for a left blank. If the line contour 26 was made in black ink for a right blank a red line associated therewith would indicate the 5 variation therefrom in a left blank of the same size, width and'style. Therefore, the operative could mark the blanks successively in pairs, each comprising a right and left blank. 7
