19 Claims.

This invention relates to machines for operating upon insoles and is illustrated herein with reference to machines for attaching ribbed strips to insoles to provide sewing ribs thereon.

In machines of the type referred to, a preformed ribbed strip is pressed against the outer surface of an insole on a support to attach the strip adhesively to the insole and thereby provide a rib on said surface suitable to serve as a sewing rib in constructing a welt shoe. These machines usually operate progressively around the periphery of the insole, similarly to an insole channeling machine, and the ribbed strip is located relatively to the marginal portion of the insole by a gage which engages the edge face of the insole and positions it laterally on the support relatively to the attaching and feeding mechanism. Since the sewing rib on a Welt insole is normally located at different distances from the edge face of the insole at diiierent portions thereof, for example, at the shank portion, the forepart or ball portion and around the toe or tip portion, the edge gage in a machine of the type referred to must be shifted relatively to the attaching mechanism to produce the desired results, that is, the variations in the position of the ribbed strip or rib widthwise of the insole margin at the different localities indicated. These variations in the position of the sewing rib on the insole are necessary to produce different widths of insole margin or feather portion at these different localities around the insole which, in turn, are desirable to facilitate the lasting and subsequent peripheral operations on the shoe, and also to produce a properly lasted and well constructed shoe.

The shifting of the edge gage in machines of this type is usually accomplished manually by the operator by means of a handle associated with the edge gage mechanism. Since the lateral position of the sewing rib is usually changed at five different places around the periphery of an insole, the operator must shift the edge gage four or five times when operating upon each insole. He must also hold the insole and guide it through the machine, taking care to keep it against the edge gage at all times. Since the insoles are fed through these machines at a relatively high rate of speed, it will be seen that the operator must be constantly alert and quick to shift the gage at the proper points around This sometimes causes fatigue which results in imperfect or defective work. Moreover, even though the op erator is giving his entire attention to the work' being operated upon, the shifting of the edgegage in this manner is still subject to variations or errors in timing or judgment so that all insoles of a particular size or style do not usually have exactly the same widths of insole margins or feathers at all portions thereof because the operator does not always shift the edge gage at exactly the same point on each insole operated upon.

An important object of the present invention is to provide a machine of the type referred to in which the position of a ribbed strip or sewing rib on the margin of an insole is determined or controlled in a manner to produce insole margins or feather portions which will be exactly the same for all insoles of the same size and shape operated upon.

To this end, the invention provides, in accordance with one feature, an improved ribbed strip attaching machine having, in combination, means for attaching a ribbed strip to an insole, a member for holding the insole having means thereon indicating the desired position of a sew ing rib on the insole, and means cooperating with said member for locating the ribbed strip in said desired position. As herein illustrated, the member for holding the insole comprises a template having a recess or depression therein for receiving the insole and holding or supporting the insole during the attaching operation. According to the present invention, the template is also provided with a surface or groove located in predetermined relation to the desired position of a sewing rib on the insole.

The means, in the embodiment of the invention illustrated herein, which cooperates with the holding means or template in positioning the ribbed strip on the insole comprises a pin or roll normally fixed relatively to the rib attaching means and adapted to engage the surface or groove in the template and thereby determine or control the position in which the ribbed strip will be applied to the margin of the insole. The ribbed strip attaching mean in the illustrated machine, as is usual in machines of this type, operates to press the ribbed strip intermittently against the insole and simultaneously to feed the combined insole and strip progressively through the machine, the insole being normally supported during this operation by a rotary table or support. Consequently, when the insole is mounted in the holding means or template referred to, the attaching and feeding means operates to feed the insole and template progressively across the support as the ribbed strip is being pressed against the outer or exposed surface of the insole. The cooperating means or pin referred to, being in engagement with the groove or surface on the template, thus causes the latter to move in a predetermined path, thereby determining or controlling the position of the ribbed strip relatively to the edge face of the insole. Since the surface or groove bears a predetermind relationship to the desired position of a sewing rib on the insole, the ribbed strip will be attached to the insole in such position or relationship. Moreover, every insole operated upon of the same size and shape will have exactly the same insole margin r feather portion because there can be no variations in the foregoing mechanical control of the insole and strip as there can be in the manual operation of the edge gage mechanism in machines used heretofore.

With the above and other objects and features in view, including improved means for varying the entire width'of the margin or feather portion' of th'e' 'insole uniformly throughout the entire periphery of the insole while maintaining the predetermined relationship'of the ribbed strip to the different portions of the edge face of the insole referred to above, the invention'will now be" described in "detail in connection with the accompanying drawings and will thereafter be pointed out in the claims.

No. 175,174, filed July 21, 1950. It'should be understood, however, that the invention is not limited in its utility to embodiment in a machine of this particular type since it obviously could be used advantageously in other machines for operating upon insoles such, for example, as insole channelin and insole reinforcing machines. As disclosed in the applica tion referred to, the ribbed strip forming and attaching machine illustrated in Fig. 1 is provided with a' frame or head 2Q upon which is mounted ribbed strip forming and attaching instrumentalities, the strip forming instrumentalities including mechanism not shown herein for folding and otherwise shaping a single strip of tape into a tape rib or strip such as that illustrated in Figs. 3, and '7 to 9, inclusive, this strip forming mechanism being fully disclosed in my copending application.

The machine is also provided with ribbed strip strip and the pressing attaching and feeding means consisting in part of a unitary pressing member or foot made up of two independent spring-pressed elements '22 and 23 (Figs. 3 and 7) arranged to press the ribbed strip intermittently against the margin of an insole to attach the strip adhesively thereto and being actuated by continuously operating mechanism indicated generally in Figs. 1 and 2 by the numeral 25, this latter'mechanism being driven from a motor by a pulley 26 and being under the control of the operator through a treadle connected to a treadle rod 28 (Fig. 1). The ribbed strip forming and attaching machine is also provided with various other mechanisms 01" meansfor adapting the machine particularly to perform the desired operation upon the insole and ribbed strip, these mechanisms including a stationary strip guide 36 (Figs. 1 and 2) for guiding the preformed ribbed strip onto the insole, and a pair of measuring fingers or feelers 3; for automatically controlling theliigth o'f th'e ribbed strip applied to the insole. Since the coiistru'c tion and operation of'th'e'se various 'mecha'n' are fully disclosed in" the cop-ending 'appiicatr n" referred to above, no detailed descriptionof'siich mechanisms will be giveri' herein'except as" be necessary to insure aprdp'erunderstan ng of the present invention. 7 The machine is furth'e'rprovided Witha rotary support 3A which is dried against height movement during the cante nses th but is adjustable heightwis ebya FE. ya for operating upon insoles whicl differ co cler'f ably in thicknesses.

"1): and thereby to determine'or' control the lateral position of the ribbed strip relatively to the in gin or edge face of the insole while thje strip "is being attached to said margin. Thedgegagef shown in the application is of the type disc in Letters Patent" of the"United States 2,326,119, granted August 10, 1943, on an application filed in the name of Frederick E. Bertrand. This edge gage, as disclosed in the patent, is under the control of the operator by means of a handle which permits the gage to be shifted into three different predetermined positions to vary the lateral position of the ribbed strip relatively to the edge face of the insole at five different portions or sections of the insole around the periphery thereof. This manual control of the edge gage is customary practice in machines of this type and in some other types of insole machines, for example, insole channeling and reinforcing machines. The locations at which the lateral position of the sewing rib is usually changed relatively to the edge face of the insole around the periphery thereof are at the shank portion, at the sides of the forepart and around the toe portion.

The operator usually places the insole on the support or table of the machine with his left hand and starts the attachment of the ribbed strip at substantially the heel breast line so that the widest margin or feather of the insole will be located at the shank portion. After passing through the shank portion of the insole, the operator moves the edge gage inwardly toward the support with his right hand while passing around one side of the forepart of the insole, thereby producing a narrower margin or feather at this portion. He moves the edge gage outwardly into its third position when passing around the toe portion of the insole in order to increase the insole margin or feather a small amount over what it was at the forepart. He then reverses this procedure when passing around the opposite or second margin of the insole until the attaching operation terminates at substantially the heel breast line at this second margin.

It will be seen that this operation requires the constant attention of the operator who must be quick and accurate in shifting the edge gage because the insole travels at a relatively high rate of speed through the machine. Moreover, the operator is not only obliged to shift the gage quickly with his right hand but, as indicated above, he must also hold the insole and assist in guiding it through the machine with his left hand. Consequently, the continued operation upon a large number of insoles or for a long period of time is apt to produce fatigue which may result in imperfect or faulty work. Another factor to be considered is that some shoe manufacturers desire to have the sewing ribs on their insoles located in exactly the same lateral position on every insole of the same size and shape. In other words, they require what are sometimes referred to as predetermined insole margins which, in insoles having ribbed strips or tapes attached thereto for sewing ribs, means that the ribbed strip on every insole of the same size and shape must be located in exactly the same lateral position around the entire periphery of the insole, including the areas referred to where the widths of the insole margins or feather portions normally change, that is, at the shank portion, the sides of the forepart and at the toe portion, this exactness applying, of course, to both margins of the insole. Such accuracy is practically impossible in a manually controlled mechanism where the changes in the lateral position of the sewing rib depend primarily upon the speed and skill of the operator even though, for ordinary purposes and in many cases, manual control of the insole margins is satisfactory because minor 6 variations in the position of the sewing rib in such cases are not important.

In accordance with the present invention, the position of the ribbed strip or sewing rib relatively to the insole margin or edge face is determined or controlled by mechanism which is adapted to provide so-called predetermined insole margins which will be exactly the same for every insole of the same size and shape operated upon. In other words, the present invention provides mechanical means, rather than manual, for automatically determining the position in which a ribbed strip will be attached to the insole in a machine in which the rib or strip is applied by a progressive or step by step action around the periphery of the insole as distinguished from a machine in which the sewing rib is applied to, or formed on, the insole by a single pressing or molding operation with the aid, for example, of a matrix, mold or other pressing implement.

In accordance with the present invention, the position of the ribbed strip relatively to the margin or edge face of the insole is determined or controlled in the machine by the following mechanism. A fiat plate or template 52 is provided for holding and supporting the insole during the strip attaching and feeding operations, this template, as illustrated in Figs. 2, 5 and 6, conforming generally in outline to the shape of a sole member and being preferably relatively thin, for example, one quarter to three-eighths of an inch thick. It may be composed of metal such as iron or steel or it may, if desired, be composed of aluminum or similar material. The upper surface of the template 52 has a depression or recess 54 formed therein which conforms accurately in outline to the shape of the insole to be operated upon, the depth of this depression being substantially equal to the thickness of the insole so that the latter will fit into the depression and be held therein with its upper surface substantially flush with the top face of the template, as illustrated in Fig. 2, the insole shown in that figure being designated by the letter A.

The bottom surface of the template 52 is provided with a cam groove or slot 56 which, as illus trated in Fig. 6, is relatively narrow in width and extends around the marginal portion of the template in a position which is located in accordance with the desired position of a sewing rib on the insole mounted in the depression 54. In other words, the groove 55 is so shaped and positioned in the template that it corresponds accurately to the position in which it is desired that the ribbed strip should be attached to the insole A mounted in the depression 54 in the opposite side of the template. Since the groove 56 is located in a position which corresponds to that desired for the ribbed strip on the insole, it will of course be located in a predetermined position relatively to the margin or edge face of the insole so that it can be used, as will presently appear, to determine or control the position in which the ribbed strip will be attached to the insole with particular reference to the relation of the ribbed strip to the edge face of the insole at the different regions referred to above, namely, the shank portion, the sides of the forepart and the tip or toe portion. At its opposite ends the sides of the groove 56 are flared outwardly, as shown in Fig. 6, to provide enlarged openings at these ends to facilitate the use of the template. The depth of the groove is preferably about one third the thickness of the template although this may be varied as circumstances require. Fig. 6 shows predetermined insole margins.

the position of the groove ttrentivery tame edge face of-the template- 52 and-also with respect-to the shape of theclepression 54 in. the opposite side of. the template. It will be observed. in that-fig.- ure that the groove bears a diiiferent relationship to the positibn ofthe insole at the differentparts of the periphery of. the latter where the positien of the ribbed" strip changes, that. is, the shank portion, the sides of the forepart and. theme portion. The precise position of the groove 56 in the template is usually ascertained by the requirements of the shoe manufacturer for whom the insole is to be made, the manufacturer usually furnishing the dimensions which he desires to have embodied in theinsole for a particular type ofwork, these. dimensions including. the distanees that the sewing rib should be located from the. edge face of theinscle at the shank, forepart and toe portions. After the manufacturer suppliessuch.informationit can be used for. all the different sizesorinsties made for the same manufacturer because. separate templates must be made for eachdifferent. size. Ccnsequentlyif a manufacturer ordersa specified quantity or lot of ihscles,v involving a number of different sizes, he need only supply one setof dimensions or figures for the. insole. margins because these same figures can-be used in constructing the template for each different size The. heel; breast line,.ball line and tip line of the insole A illustrated in Figs. and 6 are indicated diagranin'iat'ically inthe latter figure by the broken lines B, C and D. The position of the sewing rib or ribbeclf strip relatively to the edge face of the.insole,.although changed to provide different widths of. insole'margins or feather portions at these three different localities,v are not usually changed exactly on these particular lines. Inother words, the changes in the width of the margin or feather of an insole and the points where these changes take place vary in different insoles according to the desires of different manufacturers. The broken lines 13,6 and D, there.- fore, merely indicate the particular points or lines referred to with respect to the insole A, these points forming the boundaries of the different sections of the insole under consideration. It will be seen in Fig.6, that the insole shown in dotted lines below the groove he hears a difierent rei'atienship, t'dt'he groove at the three regions referred to. The changes in insole margins talie place gradually, however, and, as stated, they may vary in amount or position with difierent manufacturers. Once the exact shape and position of the groove have been definitely established in the template with respect to the position and shape of the insole in the depression 54 on its opposite side, all insoles made with the aid of that template will be exactly the same, thereby producing what has been referred to above as It should be pointed out that the groove 58 illustrated in Fig. 6 is not parallel to'the edge face of the insole indicated in that figure by the dotted outline of the depression 5i and, furthermore, the groove is nctnecessarily located so that it coincides with the median lineofthe ribbed strip which has been attached to the insole illustrated in Fig. 5, this strip being. indicated. in that figure by the letter R. The position of the groove 553 does, howevenbear a predetermined relationshipto the position'of the ribbed strip R shown in Fig. 5 and alsoto'theedge face-of the insole A. The pcsition or'shape -otthegroove with respect to the edge face of the template 52 is of no conseqiie'neesihce this. edge race perfdnris no reaction in determining or controlling" the positron ofth'e ribbed strip on the margin or the insole. Accordingly, blanlitemplates of the same outside shape. or periphery may be provided in sufficient hiimber to aceommedate a given number of sizes of insoles provided the templates are large enough to accommodate the largest size. This permits a su'flicient number of blanks to betrovided at one time or with a particular order of insoles to accommodate the entire order since the blanks may then be processed or shaped by suitable machinery into the special templates required for each different'size of insole in acetic with the dimensions" supplied by the mane facturer. Such procedure will materially reduce the expense involved in providing the templates required for a substantial number of insoles. A hole 51 is provided at the heelend of the tem= plate to facilitate the removal or the insolefrom the depression 54 after the ribbed strip has been attachedto the insole in the attaching machine.

The template 52* is utilized in a ribbed strip attaching machine, forexample, the machine disclosed in the copending application, in the following manner. As described in said application, the edge gage mechanism illustrated therein is carried by a bracket 58 (Figs. 1 and 3) ad"- justably mountedifor movement forwardly and rearwardly of the machine in a i -slot 55' formed in the casting Silt,v the bracket tir'beihg secured in position by a" binding" screw 62'. The bracket 58 may, if desired, be removed completely from the T-slot, thereby removing the entire gage mechanism from the machine to permit another type of gage mechanism to be mounted therein. The bracket 58 of the present construction has an up standing portion 64% (Fig. 3) located at the right of the casting 38 and provided with a vertical desired; being in the former a roll to reducefric Hen. The pin i l'is arranged to enter the groove 53 the template 5'2 and thereby to control mevementor the template relatively'to the'suppert 34",-as' will presently be described. The posican or the pinlfl forwardly and rearwardly of the machine with respect to the vertical axis 36 about which the support rotates is somewhat critical becauseit infl-uen'cesthe movement of the insole when the latter is fed, during the ribbed strip attaching operation, under the action of the unitary 'presser foot 22; 23:. Accordingly, the'p'osition of the bracket 53 forwardly and rearwardlyof the machine is adjustable in order thatv the' pin it may be located in exactly the right'position relatively to the center of the axis it: This adjustment is accomplished by means of: an adjusting screw it threaded into a plate ls'secured by screws tothe bracket 58-, the screw b'eing'arranged to engage asurface formed on the casting; 38. When'the position of the bracket :ter has'been. once established; the screw it may be secured inlposition by a lock nut t l.- As disclosedin the application referred-to, the'casting 3'8 isadjustable heightwise of the machine to locate the supporttin a proper heightwise position relatively to the

presser foot

22, 23 by means only when the difference in thickness becomes greater than this range. When the support is adjusted heightwise for insoles which differ substantially in thickness, the pin M will move with the support and thus retain its original heightwise position relatively to the top surface of the support and relatively to the groove 55 in the template 52. As shown in Figs. 1 and 3, the support is cut away around the margin of its upper surface to form a step or shoulder 84 at the outer edge of said surface and thus provide space into which the arm 12 can extend to permit the pin M to engage the groove 56 when the template is resting on the support, the template extending laterally a considerable distance beyond the support at the side where the ribbed strip is to be attached. As indicated above, the gage 68 and pin M are adjustable widthwise or laterally of the machine or, specifically, widthwise of the

presser foot

22, 23 and support 34, by the slot and screw arrangement H1 (Fig. 3) which secures the gage in the guideway 56. This lateral adjustment of the gage 68 permits the all-over width of the insole margin or feather to be varied uniformly around the entire periphery of the insole. In other words, adjustment of the gage 68 widthwise of the machine, moves or shifts the initial widthwise position of the template a corresponding amount relatively to the

presser foot

22, 23 and thereby widens or narrows the margin or feather portion of the insole uniformly around its entire periphery an amount equal to the amount which the gage was adjusted. Consequently, the entire insole margin or feather will be wider or narrower by that same amount although the ribbed strip as a whole will still maintain its initial predetermined relationship to the different portions of the edge face of the insole referred to above, that is, the shank portion, the sides of the forepart and the toe portion of the insole. Stated in another way, the adjustment of the gage 68 laterally of the machine changes the width of the insole margin or feather uniformly around the entire periphery of the insole without altering the predetermined relationship of the ribbed strip to the edge face of the insole at the dilferent portions referred to. This is particularly advantageous when operating upon insoles which are to be used with shoe uppers that vary considerably in thickness. Such adjustment permits the operator to compensate for the different thicknesses of shoe uppers by merely changing the position of the ribbed strip as a unit relatively to the margin or feather portion of the insole.

Although the use of the machine in obtaining exact or predetermined insole margins when attaching ribbed strips to insoles will be apparent from the foregoing description, a brief summary of its operation will be given here for the purpose of clearness. The insole A is mounted in the depression or recess 54 in the template 52 with the outer or sole-engaging sur-, face of the insole facing upwardly, the marginal portion of this surface, at least rearwardly to the heel breast line, having, been previously coated with a suitable pressure-responsive cement E (Fig. 2), which has been allowed to dry in the usual manner. The template is placed on the support 34 with the insole facing upwardly, as illustrated in Fig. 2, and with the rear or heel end of the template extending rearwardly of the machine to engage a heel gage 86 (Fig, 1) provided in the machine and arranged to position the insole initially so that its heel breast line B (Fig. 6) is located substantially under the rearward edge of the

presser foot unit

22, 23. In placing the template on the support, the operator introduces the pin 14 on the gage 68 into the groove in the lower surface of the template, this operation being facilitated, as stated above, by the flaring sides of the groove at the opposite ends thereof at the rear or heel portion of the template. The operator starts the operation of the machine by depressing the treadle connected to the treadle rod 28 and the

presser foot

22, 23 commences to press the ribbed strip R. intermittently against the insole and also to feed the insole and strip, together with the template, rearwardly of the machine to attach the strip adhesively to the margin of the insole, the heel gage having been raised automatically into an inoperative position upon treadling the machine. The position in which the ribbed strip R. is initially attached to the insole in the vicinity of the heel breast line is illustrated in Fig. '7 which also shows the

unitary presser foot

22, 23 pressing the strip against the margin of the insole while holding the two-ply rib portion of the strip in a substantially vertical position because the presser foot members in the machine disclosed in the copending application surround this rib portion while they are pressing against the opposite flanges of the ribbed strip and are simultaneously feeding the insole and strip. The attaching and feeding operation continues progressively around the margin of the insole, as illustrated in Figs. 2 and '7 to 9, inclusive, during which time the template is shifted widthwise of the

presser foot

22, 23 by reason of the pin 14 engaging the groove 56. Although the operator will usually hold or steady the template on the Support 34 during the attaching operation. he is not obliged to guide the template or otherwise control its movement with the insole on the support because the pin i l in the groove 56 performs this function automatically without attention on the part of the operator, irrespective of the speed at which the machine is operated. When the attaching operation reaches the forepart of the insole, the ribbed strip will be located closer to the edge face of the insole, as shown in Fig. 8, due to the relation of this portion of the groove 56 to the edge face of the insole. As stated above, the position in which the ribbed stri R will be located with respect to the edge face of the insole at the forepart thereof may vary somewhat with different manufacturers but, in all cases, it will be located considerably closer the edge of the insole than it is at the shank portion where a wider insole margin is desired.

' The operation proceeds around the toe portion of the insole and here th groove 56 locates the ribbed strip somewhat further inwardly from the edge face of the insole, as shown in Fig. 9, after which the insole is fed forwardly along its opposite or second margin where the position of the ribbed strip is again determined and controlled automatically at the side of the forepart and at the shank portion by the engagement of the groove 53 with the pin 14. When the attaching operation returns to the heel breast line at the opposite margin of the insole, the rib attaching mechanism is stopped automatically by the fingers 32, as described in mi copending application, and a knife 8 8 =(-Fig. provided on the machine is actuated either-manually or automatically to 'sever the "ribbed strip from the insole, this severing operation taking placeat a point which is substantially in transverse alinement with the starting position of the ribbed strip at the opposite or rst mar of the insole as shown in Fig. 5. The operator then removes the template from the support '34 and presses the insole out of the depression tit in the template through the hole '5! at the heel end thereof. The template is then ready to receive another insole of the same size and shape preparatory to attaching "a ribbed strip to that insole.

It might be pointed out with respect to Figs. 7 to 9, inc1usive, that the

presser foot

22, 28, the rotary support 34 and the pin 14, as illustrated therein, remain in stationary -'or fixed positions widthwise of the machine While the template 52 and insole A shift laterally on the support 34 during the feeding movement in accordance with the varying lateral positions of the groove 56 in the template. Consequently, although the ribs R in these three figures appear to be located in the same widthwi'se position or in vertical alinement with "each other, the position of the ribbed strip relatively to the edge face of the insole has actually changed widthwise in accord-- ance with the shape or position of the groove 56, as is clearly shown by a comparison ofthe positions of th ribbed Strips R, shown in these three figures "with respect to the edge faces of the different portions of the insole illustrated in said figures. After the

unitary presser foot

22, 23 has left the ribbed strip R, the two-ply rib portion of the strip bends inwardly away from the edge face of the insole a small amount, as illustrated in Fi s. *8 and 9, owing to the manner in which the ribbed stri-o was formed in the ribbed strip formin and attachin machine.

Having thus described my invention what claim as new and desire to secure by Letters Patent of the United States is:

1. In a machine '-for attachin ribbed strips to insoles to provide sewing ribs there n, the combination of means to attach a ribbed strip to an insole, a mem'berto hold the insole'having means thereon located in the desired varying positions of a sewing rib with respect to the insole ed e, and means cooperating with said means to locate the ribbed strip in said varying positions with respect to the insole edge.
