Patented June 7, 1938 UNITED STATES PATENT OFFICE GAUGING IVIECHANISM Application April 24, 1936, Serial No. 76,244 Renewed September 2, 1937 6 Claims.

This invention relates to gauging mechanisms and is herein shown as embodied in a form of mechanism designed to locate an unattached shoe-sole lengthwise in a certain relation to other means in a constant location. A problem with which the invention is concerned is to provide for locating the range and regulating the size intervals of a sole-gauging member in accordance with the requirements of various styles.

More specifically, the invention is shown as embodied in a form of mechanism capable of use, for example, in assembling a soleand a shankstiffener in a certain relation in a machine of the type set forth in my co-pending application for Letters Patent of the United States filed November 16, 1934, Serial No.'753,36'7.

In an assembling machineof'that type a molded steel shank-stiffener and an insole of certain selected style characteristics are assembled and permanently connected in a certain predetermined relation with the aid of two gauging abutments, one arranged to be engaged by the forward end of the shank-stiffener, and the other arranged to be engaged by the toe end of the sole. The distance between these two abutments must be Variable to provide for locating soles of different sizes, and the gauging means must provide for size gradations of different magnitudes which owe their differences to differences in style characteristics. For example, the length from the toe end to the ball-line of -a short-vamp shoe and the size gradations thereof are not the same as those of a long-vamp shoe, and those of a pointed shoe are not the same as those of a widetoed shoe. Differences in length due to various styles, and those due to various widths, are graphically shown in Letters Patent No. 1,315,171, granted September 2, 1919. Still, whatever the style may be, the longitudinal curvatures of the 40 shank-stiffeners and the corresponding last-bottoms require precision with regard to the distance from the toe end of a sole to the forward end of the shank-stiffener, errors on the score being particularly critical in high-heel shoes.

With regard, then, to conditions of the kind above set forth, an object of the present invention is to provide an improved sole-locating mechanism of universal adaptability and accuracy for a range of sizes in all styles without requiring any substitution of parts to counteract differences in size gradations due to different style factors.

As herein shown and described the-sole-locating mechanism comprises a sole-locating gauge and an operating member-by which it may be shifted to and fro in accordance with Various sizes in a given range. For practical reasons the size intervals in the range'of the operating member are constant and are indicated by a scale, while those in the range of the gauge are variable. The sizescale for the operating member is preferably supplemented by locking means providing a series of locking stations at fixed locations corresponding to the fixed size .graduations of the scale, to the end that the operating member may be secured only at stations corresponding to sizes and half-sizes. On the other hand, the variability of the size intervals in the range of the gauge is provided by regulatable transmission means through which the operating movements of the operating mem- 15 ber are communicated in a variable ratio to the gauge, and the invention provides means by which any desired ratio may be ascertained and established in the regulation of the transmission means according to the requirements of any selected style.

Moreover, to provide for complete coordination of the gauging-mechanism with some other mechanism arranged to perform an operation on a sole at a certain constant locality, the gauging 5 mechanism under consideration is organized to be shifted intact, that is, bodily, toward and from that locality and secured wherever it will locate the range of the gauge in accordance with the requirements of a selected style and a selected width-thereof.

To afford a clear understanding of the significance of such coordination by way of outlining a definite example, the organization herein shown comprises a mechanism for performing an operation on a sole at a constant locality, specifically, attaching a molded steel shank-stiffener to a sole and molding the shank of the sole and a superposed reinforcing piece. The forepart of the sole may be long or short accord- 4O ing to the particular style in process. To satisfy various requirements on this score the gauging mechanism, considering its entire assemblage, will be located at -a point that will place the range of its gauge at a predetermined distance from 4,5 the constant locality above mentioned,'this pre determined distance having been previously calibrated in accordance with the style in process, and preferably recorded in some convenient form for duplication.

The other stage'of coordination consists in regulating the transmission means to establish the required ratio between the size intervals of the operating member and those of the sole-gauge.

When both of these factors of coordination have .size of a given style.

been correctly established the gauging mechanism is ready to deal with a range of sizes pertaining to one width of one style. If some other width of that style comes to hand the operator has merely to shift the gauging assemblage to- Ward or from the constant locality to counteract differences in forepart length that exist in a minor degree between different widths of one These differences may be greater in some styles than in others, but however great or small they may be in any given style the invention provides for utilizing a scale or interchangeable scales by which an operator may be guided when shifting the gauging assemblage for some width that calls for a different setting than the one pertaining to the standard width.

Althoughthe purpose of the assembling apparatus herein illustrated is'similar to that of the corresponding apparatus more fully illustrated and described in my aforesaid application Serial No. 753,367, abrief outline thereof will facilitate an understanding of the principles and operation of the improvements upon which the present invention is predicated.

A shoe bottom unit of the type illustrated in Fig. 8 comprises an insole ll) of moldable material such as leather, a reinforcing piece II of moldable material such as compressed sheet fiber, and an intermediate shank stiffener I 2 of steel suitably arched to conform to the arch of a last of a predetermined style. Theforward end of the steel member I2 is reversely curved to conform to the break in the region of the ball line of the last where the shank portion adjoins the forepart. Since the reinforcing piece II is intended to reinforce only the heel-seat portion and the shank portion-of a sole it. is cut to a shape and size that will match those portions. At some priorstage of manufacture, one surface of each reinforcing piece H and the corresponding area of one surface of each insole are preferably coated-with a suitable adhesive such" as latex, to the end that when they are assembled and pressed one against thev other the faces so coated will cohere to maintain noto-nly their assembled relation but also the molded form imparted to them incidentally to the application of the pressure by which they are united.

, The usual procedure in assembling the parts In, H and I2 is substantially as follows. The operator, having soles, reinforcing pieces and shank stiffeners to match with regard to style and size, first places a sole, coated side up, one

supporting bed or platform in'the assembling machine and locates the sole in a certain predetermined relation to the bed with the aid of suitable gauging means with which'the apparatus is provided. Having located the sole as stated, he depresses a treadle by which a movable assemblage of apparatus is brought down and pressed upon the sole'in the region of the ball-line. This movable assemblage includes means for clamping the sole against the bed; means for locating a shank-stiffener by its forward end in a certain relation to the sole, and means by which the shank-stiffener may be clamped against the sole. Having depressed the treadle far'enough to clamp the sole, he superposes a shank-stiffener l2 thereon and locates the forward end of the shank-stiffener in its true relation to the sole with the aid of the gauging members provided for that purpose. One of these members-is arranged to provide an abutment for the forward edge of the shank-stiffener while two of them, being spaced apart in accordance with the width of the shank-stiffener, are arranged to engage the longitudinal edges to locate the shank-stiffener widthwise. depressing the treadle a little more, the operator causes still another member of the movable assemblage to bear upon the upper surface of the shank-stiffener adjacent to its forward end to Now, by 1 clamp the stiffener against the previously clamped sole.

Next, the operator superposes a reinforcing piece .I I, coated side down, upon the shank-stiffener, and with one finger locates the rear end of the reinforcing piece in register with the rear end of the sole. At this stage widthwise register of the reinforcing piece is insured by the same jaws that register the sole widthwise relatively to the bed or platform.

The composite parts of a bottom unit having been thus assembled and being maintained in true relation to each other by various elements of the apparatus, the operator shifts a movable presser from its initial position of retirement to its operative position where it overlies the assembled elements of the work. Thereupon, power-operated mechanism is set in operation to depress the presser against the assembled parts of the Work with suificient pressure to mold the sole by conforming it to the upper surface of the bed, and to conform the reinforcing piece H. to the sole and to the interposed shank-stiffener l2. The molding or conformingpressure thus applied also establishes a firm bond'of cohesion between the sole and the reinforcing'piece, and the component parts H], H and I2 are thus permanently united in the relation represented in Fig. 8. .The operator now returns the presser to its initial position or permits it to retire automaticallyyand releases the treadle by which the parts In and I2 were clamped during the application of molding pressure. Themolded unit is thus freed so that it may be removed from the,

apparatusgto clear the bed for the next cycle of operations.

7 The work-supporting bed or platform preferably comprises a plurality of individual sections includingtwo flat steel plates l3 and M (Fig.

6), a molding section l5 (Fig. 1), and an intermediate section IS. The plate I4 is mortised into a slot in the plate I 3 and is movable rela-' tively thereto in lines lengthwise of a sole, these two plates constituting in effect a smooth composite bed for the forepart of a sole. The plate I3 is afiixed to a stationary frame l1 and does not partake of any movement whatever.. The frame I! is mounted upon and afiixed to the main frame l8 of the assembling machine. The intermediate section l6 of the bed is arranged to underlie the sole in register with the ball-line and its work-engaging surface is convexed to form the usual break in that portion of a sole.

The frame I1 also supports the molding platen 5 which corresponds to the shank portion and the heel-seat portion of a sole. The platen l5 may be a block of wood and may be quickly detached if it is desired to substitute a corresponding platen of different form or style. In practice, a variety of platens l5 will be provided, each embodying the curve characteristics of the shank and heel-seat portion of an individual style of last, as set forth in my aforesaid application serial No. 753,367.

As shown in Figs. 1 and 6, a pair of short jaws and a pair of long jaws 2| are arranged to locate a sole l0 widthwise by engaging its perimeter at two opposite points in the heel-seat portion and at two opposite points in the shank portion. The two forward jaws (Fig. 1) are arranged to swing about a common pivot member 22 by which they are mounted on a vertically movable slide 23. The two rear jaws are likewise mounted on the slide 23 and are arranged to swing about a common pivot (not shown) corresponding to the pivot 22. The construction and operation of these jaws are more fully shown and described in my aforesaid application.

Another mechanism to all intents and purposes the same as the corresponding mechanism more fully shown and described in my aforesaid application includes a treadle-operated assemblage arranged tobe brought down upon a sole in the region of the ball-line to clamp the sole, to locate the shank-stiffener, and finally to clamp the shank-stiffener. This mechanism includes a vertical post or plunger 25 arranged to slide up and down in bearings projecting from the rear of the frame H. A rod 26 forms an operating connection between the plunger 25 and a treadle (not shown). An arm 21 (Fig. 6) afiixed to the plunger co-operates with a vertical guiding pin 28 to prevent turning movement of the plunger about its axis. Another arm 29 also affixed to the plunger overhangs the bed member "5 and is provided with a vertical groove that is occupied by two slides 30 and 3|, the latter being nested in the slide 30. A finger 32 rigidly secured to the arm 29 is arranged to bear on the upper surface of the forward portion of a shank-stiffener I2 to clamp the latter against a sole.

The lower end of the slide 30 is arranged to bear down on the sole to clamp the latter against the bed section l6 and it serves also as an abutment or gauge against which the forward end of the shank-stiffener may be placed to locate the latter lengthwise in a certain predetermined relation to the bed. The smaller slide 3| is provided at its lower end with two confronting fingers 33 spaced apart in accordance with the width of a, shank-stiffener. Their function is to locate theshank-stiffener widthwise, and they cooperate with the gauge member 30 to provide a stall into which the end of the shank-stiffener may be inserted. The clamping finger 32 projects into the space bounded by the abutment 30 and the two fingers 33.

This assemblage is normally raised by a ten sion spring 34 (Fig. l), the lower end of which is attached to a collar 35 on the treadle-rod 26 and the upper end of which is attached to any convenient fixture, such as an anchoring pin (not shown). When the assemblage is raised a pin affixed to the slide 30 is held against a cover-plate 38 by a tension spring 36, and a pin 43 affixed to the slide 3| is held against the upper end of the slide 30 by a tension spring 4|. The spring 36 is connected to the plate 38 by a pin 39 and to the slide 30 by a pin 40, while the spring 4| is connected to the pin 40 and to a pin 42 affixed to the slide 3|.

When this gauging assemblage is depressed to its operative position (Fig. 1) first the fingers 33 and then the member 30 clamp the sole and are arrested thereby, a slight additional downward movement of the plunger 25 being required to carry the clamping finger32 against a shankstiffener. 7

It is to be understood that the general organization of the elements hereinbefore described, with the exception of the plates I3 and I4, is virtually the same as the corresponding elements shown and described in my aforesaid application. The present description will therefore proceed from this point to set forth the novel features of the gauging mechanism by which soles of. various styles and of various sizes and widths of each style may be located in their true relation to the work-supporting bed, particularly with regard to the distance from the toe end of a sole to the forward end of a shank-stiffener.

The right-hand end of the stationary frame I? is formed with guideways for an adjustable frame 50. As shown in Fig. 4, the guideways comprise flat supporting surfaces or tracks 5|, a guiding flange 52, a gib 53 and a retaining flange 54 for the outer face of the gib. As shown in Fig. 1, these guideways are parallel with the plane of the plates l3 and I4 of the work-supporting bed. The purpose of the frame is to support a toegauge 55 and mechanism by which this gauge may be adjusted toward and from the gauge 3%. The confronting faces of the gib 53 and the frame 50 are complementally beveled to operate with a clamping effect in consequence of depressing the gib toward the underlying supporting surface 5|. To obtain a clamping effect, a cap-screw 51 is afiixed to the frame I! by a pin 56 and is arranged to project loosely through a hole in the gib, the upper end of the cap-screw being provided with a screw-thread to cooperate with a nut formed with a handle 58. Preferably the nut and the gib' are counterbored to provide a chamber for a compression spring 59, the purpose of which is to maintain slight pressure of the gib against the frame 5|! even when the nut 58 is loosened to permit adjusting the frame.

The adjustable plate M of the work-support ing bed is superposed upon the frame 56 and is slidably connected thereto by cooperative dovetail formations shown in Fig. 4, the purpose of this feature of construction being toprovide for adjusting the toe-gauge 55 which is carried by the member I4 and afiixed thereto, as by screws,

so that it may extend across the fixed work-supporting plate l3 and move relatively thereto for purposes of adjustment. The adjusting move-.

ments of the toe-"gauge are derived 'from'an operating lever 60 (Figs. land 3) mounted on'the frame 50 and connected thereto by a fulcrumpin 6|. Operating motion is communicated from the lever 65 to the toe-gauge by regulatable transmission means comprising a link 52, an arm 63 and'a link 64. A pivot pin 65 connects one end.

' including the toegauge 55, the operating lever finger-nut 82 (Fig. 6).,

. tion 85 arranged to cooperate with the scale II 6B and the transmission means connecting them may be shifted bodily toward and from the gauging member 30 by sliding the frame 50 in its guideways, and although the frame 50 may be secured at any position of adjustment by the gib 53 and the clamping, member 58 the toe-gauge may be adjusted. individually by the operating lever 60 while the frame 50 is secured. I

The operating lever 60 is provided with two scales HI and II. The scale 10 corresponds to a range of sizes and half-sizes of soles. A pointer 12 afiixed to the frame 50 is arranged to cooperate with this scale. Moreover, the frame 50 is provided with a series 13 of teeth and notches to provide locking stations corresponding to the size graduations of the scale 10. As shown best in Fig. 6, the handle portion 14 of the operating lever 60 is bored to provide a bearing for a looking pin 15 arranged to cooperate with the teeth and notches 13. The operating lever also carries a latch 16 by which the pin 15 may be latched in an inoperative position when it is desired, for example, to leave the operating lever unlocked. The latch 16 is connected to the operating lever by a pivot pin 11 and is arranged to cooperate with a lever 18 by which the pin 15 may be moved in and out. The lever 18 is connected to the operating lever by a pivot pin 19.- The'latch I6 and the lever 18 are so related that a single spring engaging both serves two purposes, namely, to shift the pin 15 to its locking position and to maintain the latch in'its latching position. To re' tract the pin 15, the operator has merely to press the left-hand end of r the lever 18" toward the latch 16, and if this motion is of sufficient length the lever and the pin will be caught by the latch.

The latch may be readily displaced to release the lever.

To provide for shifting the connecting pin 6 toward and from the fulcrum pin 6| the operating lever 60 is provided with a slot 8|. The pin 68 projects through and beyond this slot and its forward end "is threaded to cooperate with a A flanged bushing 83 surrounding the pin 68 cooperates with a'flange 84 on the pin to clampthe lever when the nut 82 is tightened. A rabbet on the front face of the lever cooperates with an edge of the bushing to prevent the latter from turning. -As shown in Fig. 5, the bushing is provided with an index porto indicate various settings of the pin 68., The purpose of the adjustments afforded by this. con struction is to regulate the size intervals in the range of the toe-gauge 55 notwithstanding constance in the size intervals of'the operating lever 60.

.7 The slot 8| is curvedandthe length of its. radiusof curvature is the same as the distance between the center of the pin 68 and the center regulation of the size intervals in the range ofthe toe-gauge. V

Asshown'in'Fig. 6 the stationary plate l3 of the work-supporting bed is provided with a stylescale with which the toe-gauge 55 cooperates. This scale may be utilized in the first instance to provide readings to be recorded ona style-chart (Fig. '9) where theymay b'e supplemented by readings obtained from the regulatory scale H on the operating lever 60. These-readings when once recorded on a style-chart in conjunction with respective style symbols or designations will 7 enable an operator to reproduce, whenever necessary, the adjustments required tocoordinate the gauging mechanism in accordance with any style so charted.

The gauging mechanism may also be provided with a supplemental scale 9| (Fig. '7) indicative of various widths, but if, as shown, the intervals in the scale 90 are made exactly equal to those in the scale 9| the latter scale may be ignored or even omitted after an operator has acquired facility in the use of the gauging apparatus. This does not mean that the letters or symbols applied to the scale 90 have any significance with respect to, various widths and theyshould be disregarded when a change of adjustment is made for a.

different width by reference tothis scale. a

; The manner of using the described gauging apparatus will be described first with regard to 0btainingreadings to berecorded, for example on av style-chart, and afterward with regard to utilizing such readings when adjusting the gauging mechanism for operation in assembling a sole and a shank-stiffener in a prescribed relation to each other.

-To*obtain data'for' recording, the only requisites-are two size models of any given style, for example a model of size 5 and a model of size 9, both of thesame style and both of an arbitrary standard width, such as width A. Style designations willpresumably be numbers obtained from lasts likewise numbered. Each of the two size models may embody the make-up of the composite 'unit illustrated in Fig. 8 and will be accurate with regard to the distance from the toe end of the sole to the forward endof the shank stiffener l2. To facilitate describing a typical example of procedure, it will be assumed that the'operator is about to obtain data for a chart I from two size models one of size 5 and the other of size 9, both ofwidth A, and both of style #125.

The operator first sets the operating lever 60" toregister 5 on the size-scale T0 (Fig.3) and locks it in-that position. Then he places the model of size 5 on the operating bed or platform,

so that the forward end of the steel shank-stiffener I2 will touch the gauge 30 when the latter is brought down to clamp the sole. Next, if the toe-gauge 55 does not abut the toe end of the sole, he slides the frame 50 in whichever direction is necessary to obtain that result, and tightens the clamp 53 to preserve the setting of the frame for that style. The model of size has now fulfilled its purpose and may be set aside.

Now the Operator shifts the operating lever 60 up the size-scale some distance beyond 9 to provide, temporarily, a margin of clearance, but in this case he latches the locking lever 18 so that the pin will not function, since it is desirable, at this stage, to leave the operating lever 69 freely movable. The model of size 9 will now be placed on the operating platform, its shank-stiffener against the gauge 30 as shown in Fig. 1, and the operating lever 60 will be moved just enough to bring the toe-gauge 55 against the toe-end of the sole which is now clamped against the bed. Now, if the size-scale 10 does not register exactly 9 some regulation is necessary to coordinate the gauging mechanism with the size-intervals of the style to be charted.

Since the frame 50 has already been located and secured in its true position for the selected style, and the toe-gauge 55' has been located individually in its true positionfor size 9, (Figs. 1 and 6) it is desirable to secure the gauge temporarily in that position to facilitate the regulating procedure about to follow. Here, the operator turns a screw 92 (Fig. 4) by which the toe gauge may be tightly clamped to the carriage in preparation for the next step. The screw 92 is screwed through a bell-crank lever 93 and abuts the frame 50. Consequently, when the screw is turned it operates the lever 93, one arm of which applies upward pressure against a lug on the under side of the member I4, the gauge 55 being thereby secured to the frame 50. The fulcrum pin 94 of the lever 93 is aifixed to the frame 50.-

The operator now turns the nut 82 to release the pin 68 and moves them toward or from the fulcrum pin 6|, in whichever direction may be necessary to locate the operating lever 60 in its true position for size 9 as indicated on the scale 10. This result is pictured in Fig. 1. When this is done he tightens the nut 82, and thus completes the regulation of the transmission means by which the gauging mechanism is brought into coordination with the. size intervals of the style selected. To restore the mechanism to operative condition the operator loosens the screw 92 to release the toe-gauge and trips the latch 76 to release the locking pin 15.

The data now available for recording on a style-chart (Fig. 9) comprises three items, viz., first, a style-number (125) with which both models are marked; second,a reading (F) obtain,- able from the forepart scale 90 when the operating lever 69 is set for size 5 (no other) and third, a reading (41) obtainable from the regulatory scale 1| (see the setting pictured in Figs. 1, 2 and 3). These items may be recorded on a chart for future use, for example, in the manner shown in Fig. 9. For another style such as 131 the reading on the scale 90 may be H-1 for size 5, and. the reading on the scale H may be 3.

With such a chart an operator may quickly coordinate the gauging mechanism for any charted style without again using any model. For production purposes soles and shank-stiifeners are grouped according to style and size, though one size of shank-stiffeners is commonly used with three or four sizes of soles. Furthermore, soles are grouped according to various widths. These groups are identified in some manner, as by tags, when supplied to the operator of an assembling machine, so that he may select thecorrect shank stifieners for each group of. soles.'

When the operator has noted the style-number of a new group of soles he will refer to the style-chart (Fig. 9), and if that number (e. g.

recordings and initial adjustments, the operator has only to alter the setting of the frame 50 for any other width of a selected styleafter'making the aforesaid adjustments for that style. To do so he will shift the frame 50 to the right from the standard location for widths wider than A, and to the left for widths narrower than A. For his guidance inthis procedure he may use a special width scale 9| (Fig. 1) or one of similar type but of longer or shorter scale intervals, according to the characteristics of the style in process. Having selected the appropriate width scale 9| and having placed it on its shouldered bed on the frame IT, as shown in Fig. 4, he will first adjust it lengthwise to place the A in register with the index 95 while the frame 50 is set for width A. The index 95 is aflixed to the frame 50. He will then secure the scale 9| to the immovable frame IT by tightening the clamping screw 96 (Fig. 4). The width scale is now in the correct position to indicate the various settings of the frame 50 for all widths of the selected style. Consequently, as various widths of that style come to hand, the operator may take his readings from the scale 9| when altering the setting of the frame 50.

In operation, the operator has only to shift the lever 60 for various sizes of soles of any selected width of a selected style. For another width of the same style he may shift the frame 50 to another station where it will remain for all sizes of that width. For another style he has only toshift the pin 68 along the regulatory scale H with or without shifting the frame 50, as the case may be.
