MARKING AND GAUGING DEVICE Filed March 9, 1922 Patented Apr. 29, 1930 UNITED STATES PATENT OFFICE GEORGE N. GORDON, F BROCKTON, MASSACI IUSE'ITS, ASSIGNOR TO UNITED SHOE MA- CHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY MARKING AND GAUGING DEVICE My invention relates: to the marking of shoe parts and to anovel form of gauging device Which, while'capable-of more general use,'is especially adapted for use in positioning shoe parts, such as insoles, as they are the heel-breast line on insoles for welt shoes,

to provide a guide for the operation of the Welter, and for otherpurpose's.

Insoles, especially those of'the type known as .Economy insoles, are usually provided with cuts determining the opposite ends of the channel lip and with marks on opposite surfaces approximately at the heel breast line of the finished shoe. Thesemarks and cuts are gauged from the heel end of the insole,

but when the insole is afterwards tacked orotherwise secured to alast 1n the assembling of the shoe it is placed with its toe end in registry with the toe end of the last. Various operations, such as the channeling, result in greater or less distortion of the insole and for this and other reasons the insoleis in some cases made'somewhat longer than is 'actuall'y required. In such instances the insole is trimmed d'ownto theproper size. after it has been secured to the last. Obviously such asequence of operationsmakesit extremely dithcult'to provide for accuracy in making" the marks which designate the heel breast line" prior to trimming down the insole.

Moreover, in using Economy insoles a canvas reinforcement is'secured to the channeled surface of each insole terminating approximatelyat the heel breast line, and unless considerable careisexercised in placing this reinforcement on each insole it will cover the previously made. mark which would otherwise serve as a guide in attaching the welt. It is an object of the present invention to obviate these-and other difficulties by providing a device for marking an insole after it. has been trimmed and reinforced; Marking' the sole in such a. manner provides a cl'ear 'di-stinct guide for: the operation of attaching the welt. The mark is accurately placed since it is gauged from the trimmed insole, and if the reinforcement"extends too far back the marking extends across the surface thereof where it is in plain sight.

From a diflerent point of view the invention may be regarded as comprising a yieldingly mounted marking device which can adapt itself to an undulating or uneven surface such as the ribbed surface of a channeled and reinforced insole. As illustrated, a marking roller runs in a reservoir of ink and is urged upwardly againstthe work so that during relative traversing movement of the work and the roller the latter will automatically adjust itself to the varying'heights of the difierent parts of the work.

It is desirable in performing such an operation as indicating the heel breast line to provide an adjustment so that the marking device may be utilized with equal facility, in operations upon the insoles of either mens or womens shoes. A further object of the invention, accordingly, is to provide improved gauging means which can be adjusted for different sizes of shoes, and in which an auxiliary adjustment is provided to changethe' reading of the device which indicates the position of the gauge proper. In the illustrated device which is hereinafter described, a gauge setting member carries a pointer whicl'i co-operates with a scale which is normally fixed, and the scale is arranged to be moved and clamped in different positions, in the present instance the purpose being to change" the setting of the gauge according as the device is tobe used on insoles for mens or for womens shoes.

Other objects and features of theinvention and various novel combinations and improved constructions will be apparent from the following description of air illustrative device shown in the accompanying drawings,

in which Fig. l is an isometric View, partly broken away, showingan insole marking device;

Fi 2 is a section longitudinally through the evice shown in Fig. 1; and

Fig. 3 is a perspectiveshowing the heel end of a last with an Economy insole attached and with a mark across theinsole such as is produced by the machine shown in Figs. 1 and 2.

7 mens shoes. The scale is adapted tov be The improved fmarking device shown in the drawings comprises generally a suitable support 10, a novel form of gauge 12 mounted I on a slide 14 operated by a threaded conneca slot in the scale 22. 1 01 reasons hereinbefore explained, this scale is illustrated as being arranged to seat against as'uitable stop 26 to be positioned fol-use in operating on insoles for womens shoes or against a second stop 28 for use in operating on insoles for clamped ineither of thetwo working positions referred to'by tightening the screw 24. It will be apparent that the gauge 12 may be positioned by an operator according to there'ading of pointer 20' on scale 22, and that the operator may then pass insoles acrossthe top ofthe support 10 with the heel end of each insole in engagement with the gauge 12. V

In order to gauge from the heel end of an 7' insole, if it is not desired to removeit from a man) which it has been secured, the gauge 1 12 is provided with a relatively thin vertical portion to engage the insole and is cut away above this vertical portion on a bevel to avoid engagement with the bulge of the last above the insole as shown in Fig. 2. The beveled scribed, each one is provided with an inked. line substantially at its heel breast line by a in thetop 36 of 'an'ink reservoir38 which is;

portion of the gauge12 atfords a convenient means for guiding the soleedge into engage-V ment with the relatively thin vertical portion of the gauge, thereby facilitating the positioning of the'insole f r the marking operation. 7

As thelpreviously prepared insoles are movedacross the top of support 10 as deyieldingly mounted marking device illustrated as a roller or Wheel 30 carried by an oscillating arm 32 which is urged upwardly against the work by'a spring 34. The roller 30 extends upwardly through a suitable slot arranged so that the lower part. of the roller "30 is constantly immersed in' the ink contained in the reservoir; WVhen an insole or other uneven piece of work is passed across amarking deviceof this kind, and a pro ec- 7 tion such as the sewing rib or the channeled portion of the sole is' encountered, the roller- 30 yields downwardly in an arcuate direction toward the right and rides over such proj ec tion without at any time losing. contactwith .the work. Thus it will be apparent that even when'operating on work which is as uneven as channeled and ribbed insoles, a-clear'and distinotline such'as indicated in Fig. 3 at 40 will be formed onv each insole, 42 shown in :that figure as being mounted on a last 44.

While a particular construction been illustrated and described in explaining my invention it is not my intention to limit its scope thereby or otherwise than by the terms of the appended claims. 7 Having described my invention, what I claim as new and desire to secure by Letters able gauge cut away to engage the heel end ofan insolewithout engaging a last to which the insole is tacked.
