- 19s (or. 12-33) Objects of the invention are to provide in a cement sole attaching machine improved means for receiving and supporting shoes and soles and for introducing them to the operating instrumentalities of the machine, to provide improved l0 mechanism for positioning an outsole in proper transverse relation to the bottom of av shoe in accordance with the width of the shoe before pressure is applied thereto, and to provide improved means for locating the sole longitudilfi nally of the shoe and for positioning the toe end of the sole forwardly of the tip line relatively to the corresponding portion of the shoe bottom. Further objects of the invention are to provide improved pressure applying means whereby a predetermined pressure can be applied to central portions of the forepart and heel portions of a shoe and sole and substantially greater pressure can thereafter be applied to their marginal and shank portions, and to provide a novel method and improved means for applying prasure to the marginal and shank portions of the shoe and sole progressively from the toe to the heel end of the shoe.

In the illustratedconstruction the sole-re- 0 ceiving and introducing means comprises a pair of gripping members which have also a sole gaging function and which are arranged to engage a sole at its forepart and heel portion and to move it into a predetermined heightwise po- I sition between the shoe bottom and the pressureapplying means. The grippers swing about an axis which is located below the pressure-applying means and, when'the machine is at rest, the grippers are inclined outwardly toward an operator so that the sole can be conveniently presented thereto. The shoe engaging and supporting means, as illustrated herein, comprises a member having abutments thereon for engaging a shoe and holding it with its side toward the operator, this member being arranged to be gaging the shoe and sole. the shoe gages being arranged to be brought 'yieldingly against opposite sides of the shoe at the forepart and heel portion to measure or caliper the width of the shoe at such portions. The sole gages, which are similar to the shoe gages, cooperate withihe' 5 sole-gripping members and are arranged to engage the inner edge of the sole at/the forepart and heel portion substantially opposite the gripping members. The sole gages and grippers are then centralized relatively to the shoe gages by 10 mechanismoperating independently of the means for swinging the grippers into operative position, thereby shifting the sole laterally of the shoe until the former is located in proper transverserelation to the shoe bottom .in accordance 5 with the width of the shoe which has previously been determined by the shoe gages. The solepositioning mechanism is adapted to operate either upon flat soles, molded soles or upon soles which have been shaped to conform to the lon- 2o gitudinal contour of the shoe bottom, for example, by the method and apparatus disclosed in United States Letters Patent No. 1,772,038, granted August 5, 1930, upon the application of H. A. Davenport and N. F, Hopkins and further 25 disclosed in Letters Patent of the United States No. 1,939,750, granted Dec. 19, 1933, upon an application filed in my name.

In orderto locate the sole longitudinally of the shoe before the sole is moved into pressure- 30 receiving position, separate'mechanism is, provided which, as herein illustrated, is positioned by the shoe and is arranged to be moved into and out of operative position in a predetermined path extending parallel to the longitudinal axis of 35 the shoe. An abutment is provided which is adapted to engage the toe end of the shoe and thereby to locate the mechanism in such a position that a second abutment thereon can be utilized for determining the/position of the sole longitudinally of the shoe. This mechanism is also provided with *"gages or fingers constructed and arraged to engage the shoe and sole at points corresponding approximately to the tip -line of the shoe toposition the portion of the 5 sole forwardly of the tip line laterally of the shoe bottom, the construction of the mechanism being such that engagement of the shoe-engaging fingers with the shoe controls the subsequent positioning movement of the sole-engaging 50 fingers. In accordance with a feature of the invention, the fingers which engage the sides of the shoe and sole nearest the operator are arranged to be rotated with the sole-gripping members about a common axis'so that the abutment associated with the sole-engaging fingers will be in a position to determine the location of the sole longitudinally of the shoe as the sole is presented to the gripping members.

The pressure-applying means of the illustrated construction comprises an inflatable pad mounted on a sectional supporting member and adapted to apply pressure to the sole and shoe. The inner or central portion of the pad is considerably thicker' than the surrounding portions thereof and consequently is relatively solid, this portion being constructed and arranged to apply a limited pressure to the central portions of the shoe and sole. The marginal portions of the illustrated pad are provided with a plurality of separate chambers or compartments which may be inflated by fluid under pressure. An inflat able compartment also extends under that section of the pad which underlies the shank portion of the shoe and these compartments, when inflated, displace the marginal and shank portions of the pad sufliciently to apply substantial pressure to corresponding portions of the sole and shoe, this action taking place after pressure has first been applied to the central portions of the shoe and sole by relative movement of the pad and the shoe and sole. Preferably, and as illustrated, the shoe and the central portion of the pad are moved relatively to each other to grip the sole with a force sufllcient to maintain it in position while the sole gripping members are withdrawn therefrom, fluid-pressure-operated means being provided to eflect this relative movement. The pressure exerted by the fluid-pressure-operated means may be regulated and controlled as desired by pressure regulating means to insure that the sole will be gripped firmly between the shoe and the pad and also to determine the amount of pressure which will subsequently be applied to the central portions of the shoe and sole. Further relativemovement of the shoe and pad operates to return the central portion of the pad substantially to its original position and to apply limited sole attaching pressure to central portions of the forepart and heel portions of the shoe and sole.

In applying sole attaching pressure to the marginal and shank portions or the shoe and sole, novel means comprising a slide valve and pressure regulating means are provided for automatically inflating the compartments of the pad independently of each other commencing with the marginal compartment in the forepart of the pad and then successively inflating the shank compartment and marginal compartment at the heel portion of the pad. The pressure at the marginal and shank portions of the sole is thus applied progressively from the toe to the heel endto each other lengthwise of the shoe bottom during the pressure-applying operation and thereby displace the sole relatively to the shoe bottom as might be the case it pressure were applied to the shank portion of the sole simultaneously with, or after, the application of pressure to its forepart and heel portions. The pressure regulating or controlling means for each compartment permits the pressure at different portions of the sole to be applied in different amounts depending, for example, on the type of shoe being operated upon or upon the manner in which it is desired to have a particular sole conform to the shoe bottom.

In its method aspects the invention consists aoereoo broadly in cement attaching soles to shoes by first applying a predetermined pressure to central portions of a sole, in order to level the sole against the shoe bottom without producing irregularities in the outer surface of the sole, and thereafter applying a substantially greater pressure progressively to the marginal and shank portions of the sole to secure a firm attachment of the sole to the shoe bottom. In accordance with an important aspect of the method the pressure at the marginal and shank portions of the sole may be regulated so that the force exerted on either the forepart, shank or heel portion of the sole' may be creued or reduced relatively to the pressure at the other portions or, if desired, the pressure applied to all of these portions may be equalized. The application of pressure progressively and in diiferent amounts to different portions of the shoe bottom will not only eliminate any undesirable relative movement oi the sole and shoe during the pressing operation but will also insure that the sole is pressed firmly against the shoe bottom at those portions where pressure is most needed. for example, at the shank and marginal portions of the sole.

The above and other objects and features of the invention, including novel means for maintaining the shoe in pressure-receiving position while it is being moved relatively to the pad, means for effecting heightwise and lengthwise adjustments of the diflerent gages and positioning devices, and means for simultaneously eflecting corresponding adjustments of the sectional pad support, as well as other novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and will be pointed out in the appended claims.

Since these mechanisms operate in substantially the same manner it will not be necessary to illustrate both for a complete understanding of the invention. Accordingly. only the mechanism at the right-hand side of the machine has been shown in the drawings.

A shoe whichis to have its sole attached by cement is first prepared by roughening the overlasted portion of the upper and coating it with cement. The shoe is then presented to the machine together with an outsole the marginal portion of the attaching face of which has also been roughened and coated with cement. Preferably, the outsole is shaped to conform substantially to the longitudinal contour of the shoe bottom although conforming the outsole to the shoe bottom is not essential since the' machine is adapted to operate upon either flat or conformed soles. A method and apparatus by which soles maybe conformed to the longitudinal contour of the shoe bottom, upon which soles the present machine is designed to operate, are disclosed in the Davenport andHopkins patent and in Patent No. 1,939,750 referred to above. The machine operates to position the shoe and sole rela-.

' tively-to each other and to apply pressure suiii-.

cient to attach thesole either temporarily or V permanently to the shoe bottom depending on 1 use today, for example, rubber'cement. the solethenature of the cement used in attaching the soleto the shoe. If the cement is of a quick drying type, such as are many of the cements in will be permanently attached to the shoe bottom by maintaining the pressure of the machine for about 15 or 20 seconds which is the speed at which the machine normally operates. with such cements, therefore, the machine can be operated at full capacity while attaching soles permanently to shoe bottoms. When a cement is used suclras pyroxylin cement, which requires a considerablylonger period in which to set, the

machine is adapted to applv the'usual pressure of between 60 and pounds to the square inch or a short period of time, as indicated above, in order to stick the sole temporarily to'the'shoe bottom. The-shoe is then removed and placed in a pressing device similar to a shoe rack and constructed and, arranged to apply lighter pressure to the sole and shoe while the pyroxylin cement'is setting. This aspect of the invention will be explained in more detail after the machine has been described and the method of attaching soles to shoes permanently with a quick drying rubber cement has been fully explained.

As illustrated in Fig. 1, the machine comprises a frame having vertical rear and side walls I. (only one of the latter being shown in Fig. 1) and an upper portion [2 in the form of a relatively narrow shelf which connects the side walls and carries at the right-hand side of the machine a pair of upwardly extending brackets ll and I6. In the upper ends of the brackets ll and I6 (Fig. 2) is mounted a horizontal shaft III which extends widthwise of the machine .and is secured in the bracket M by a taper pin i5. Fu1-. crumed on the fixed shaft 3 is a lever 20 one arm of which extends rearwardly and is pivotally connected to a yoke piece 22 threaded on the upper end of-a vertical rod 24. The lower end of the rod 24 (Fig. 4) is pivotally connected to a lug 25 e xtending upwardly 'from the outer' extremity of a lever 26 fulcrumed on a fixed shaft '28 which is mounted in the lower portion of the frame Ill. The lever 26 carries a roll 30 which rides on the periphery of a cam 32-keyed to a cam shaft 34 journaled in bearings formed on the opposite side walls of the frame, the roll 30 being held against the cam by means of a spring 35, one end of which is connected to the lever 25 and the other end to a horizontal rod 31 mounted in the frame. The cam shaft 3| is rotated by means of a pulley (not shown) driven by a belt from any usual source of power or the pulley may, if desired, be motor driven. A one-revolution clutch similar, for example, to that disclosed in United States Letters Patent No. 1,549,243, granted August 11, 1925, upon an earlier application of mine may be utilized for operating the machine, although other types of clutches may be used ifv preferred, the invention not being limited to the particular clutch referred to.

The clutch is also provided withlany usual or conventional means by which it is automatically thrown out of driving operation after a part of the cycle has been completed, the 'operator tripping the clutch again to complete the cycle .of the machine.

The'lever 20 referred to above :has a forwardly extending arm which is provided at its outer end with a circular lug 36 (Figs. 2 and 3) which projects laterally from the side of the lever and is' arranged to engage the flat side of a semi-cylindrical mg 39 formed on a projection ll extending rearwardly from an elongated huh portion" l2 (Figs.- 1 and 2). of a downwardly projecting arm II. The hub portion 421s rotatably mounted on r a rock shaft ll journaled in.bearings formed in-a pair of forwardly extending arms 4, 48 (Kg. 1) of a yoked lever 5| (Fig. 2) which is fulcrumed on the fixed shaft it. The lug 3G is held in contact with'the semi-cylindrical lug ll by means of a torsion spring 5| which encircles the hub of the lever 29 and'hason'e end curvedto engage the lug 3i and the other end-engaging the lug 38, thus normally holding the adjacent surfaces of the lugs together. This-arrangement providesa yielding connection between the cam-operated lever 2| andthearmll sothatthe latterwillbe rotated about the shaft 'ina coimter-clockwise Y5 direction, as viewed in Fig. 2, by clockwisemovement-of the lever 20, reverse movement of the arm being effected by counter-clockwise movement of .the lever 20. When the hub 42 is rotated in a counter-clockwise direction the arm 40 is arranged to contact with a fixed abutment 53 formed on the frame in order to limit the rotation of the'hub 42 and the rock shaft 44, which turns with the hub as will be hereinafter explained. The arrangement is such that the arm 40 will always contact with the abutment 53 before the forward end of the lever 28 is rotated by the cam 32 into its highest position, the yieldable connection between the lever and the arm permitting the lever to continue its rotation for the full throw of the cam after the arm 48 has contacted with the fixed abutment 53.

The rock shaft has rightand left-hand screw threads formed therein (Fig. 1) which extend in opposite directions from the central portion of the shaft to its bearings in the arms 46, 48, the bearings being split to facilitate assembling the parts and being held together by clamping screws 49. The elongated hub 42 of the arm 48 occupies the entire space between the bearings 48 and 48 and has a substantially cylindrical opening or recess 52 formed therein-which terminates a short distance from the left-hand end of the hub and, at the under side of the hub, forms a T-shaped slot 54 (Figs. 1 and 2) which extends across the full width of the hub.

Mounted on the rightand left-hand threaded portions of the rock shaft 44 are lastand shoeengaging members 58, 58 which furnish means for engaging and holding a shoe in a substantially upright position during the operation of the machine, this mechanism being hereinafter referred to as the shoe-jacking mechanism or the jac The members 58 and 58 extend downwardly from the shaft 44 and are provided with T-shaped'portions which enter the slot 54 and'maintain the members in predetermined positions relatively to the hub 42 and also cause the shaft 44 to rock when the hub is rotated. The member 58 carries a downwardly extending arm 51 which is forked at its lower end and has pivotaily secured thereto a last pin holder 68 having a convex face from which projects downwardly alast pin 8| adapted to enter the hole in the cone of a shoe last. The holder 60 fulcrums'about a pivot pin 83 extending through the forked end of the arm 51 and encircling the pin is a torsion spring 82 *which tends normally'to urge the last pin ii toward the left, as viewed in Fig. 1.

The shoe-engaging member 58 is also provided with a downwardly extending arm 58 the lower end of which carries a substantially horizontal plate 84 which acts as a shoe rest adapted 'to engage 'the forepart of a shoe. The under side of the plate is shaped to conform substantially to the transverse curvature of the forepart of a shoe' and is 'covered with felt orleather to prevent scarring the shoe upper. the rock shaft 44, as viewed in Fig. .1, is reduced in diameter and has secured thereto a hand wheel 88 by which the shaft can be rotated manually to adjust the shoe-eng in members 58, 58 toward or away from-each other along the threaded portions of the shaft and thus position the shoeengaging members in accordance with the size of shoe being operated upon. In jacking a shoe A (Fig. 1 the last pin 8| is inserted inthe hole in the cone of the last L and the toe end of the shoe is pressed downwardly untiLit'can be moved under the toe rest 84. The operator then re- The right-hand end of downwardly and enters a vertical opening in a casting I4, the lower end of the stud having a head which fits an enlarged portion of the opening and thus prevents the stud from being pulled upwardly out of the casting. A compression spring I6 is interposed between the casting and the yoke to provide a yield between the lever 50 and the casting the purpose of which will be hereinafter explained. The central portion of the casting I4, as shown in Fig. 2, is hollow and its lower portion I5 is cylindrical in shape and is provided with a vertical bore to receive the upper end of a relatively large shaft I8 which extends into the hollow portion and is held therein by a collar 80 so that the casting "forms the means of connecting the lever 58 to the vertical shaft 18. At'its lower end the shaft I8 is adjustably connected by means of a yoke piece 82 to the outer end of a'lever 84 fulcrumed on the fixed shaft 28 (Fig. 4). The lever 84 carries a roll 86 which rides on the periphery of a cam 88 keyed to the cam shaft 34, the roll being held against the cam by a tension spring 90 extending between the lever 84 and the fixed rod 31. A heavy compression spring 94 (Fig. 2) encircles the intermediate sure applying operations late'rto be described.

Whenthe shoe is jacked the jacking mechanism is positioned as shown in Fig. 3 with the arm 40 and the shoe engaging members 58 and "extending forwardly at an angle of about 45. After the operator has jacked the shoe and has tripped the clutch, the cam 32"(Fig. 4) is rotated in a clockwise direction to lower the roll 38 (which is then on the high part of thecam) and to cause the rod 24 to descend and swing the forward arm of the lever 28 upwardly to the position shown in Fig. 2. The hub 42 isthereuponrotated about the shaft 44 in an opposite direction until the arm 48 contacts with the fixed abutment I3, thereby locating the last and shoe in a substan-, tially upright position, as shown in Fig. 2. After the arm 48 contacts with the abutment 58 the spring M will yield as explained above to permit the lever 28 to continue its rotation until the roll 88 is ridingon the low partof the cam 82.

The mechanism for introducing the sole -be'- tween the pressing means and the shoe bottom and for supporting it in such position before pressure is appliedto the shoe and sole will now be described. This mechanism comprises a pair of upwardlyextending arms or levers 88 and Jill- (Flg. 1) mounted for swinging movement about on 'the opposite side walls of the frame II). In

4 their initial positions the swinging levers 88, I88

are inclined outwardly at an angle of about 45 and when operating are swung into a substantially vertical position by a cam I84 mounted on the cam shaft 84 (Fig. 2). 4 Fig. 3 shows the position of theupper end of the-lever 88 relatively 7 I member I08 (Fig. 4).

to the shoe-jacking mechanism when the parts are in their initial or inoperative positions.

The lever 98 is arranged to operate on the heel portion of the sh'oe and accordingly is somewhat longer than the lever I which is arranged to operateon the forepart and is located approximately at the ball line of the shoe. Projecting inwardly a short distance from the upper end of the lever 98 (Fig. 2) is a boss I which is bored horizontally, and slidably mounted in this boss is a sole gripping member I06. Near the upper end of the lever I00 is a similar boss I0'I which carries another sole-gripping Each of these gripping members comprises a cylindrical shankportio having at its inner end a raised projection (see Figs. 2 and 4) which has extending inwardly from its under side a horizontal lip or finger arranged to engage and support the under side of the outsole. Leaf springs III, II3 secured respectively by screws to the upper surfaces of the raised portions of the members I06, I00, extend inwardly over the fingers to form two pairs'of gripper members between which the edge of the sole may be readily inserted. The leaf springs, are strong enough to press the edge of sin outsole B firmly against the supporting fingers, as shown in Fig. 4, so that the outsole will be maintained in a substantially horizontal position after the levers 98, I00 have been swung into operativepositions. The shank portions of the gripping members I06, I08 extend through the bosses and the levers 98 and I00 and, near their outer ends, are provided respectively with laterally project ing pins H0, H2.

The lever 98, which is opposite the heel portion of the shoe, is arranged to be rotated into and out of operative position about the shaft I02 by means of an elongated plate II4 (Fig. 5) upon which the lever is slidably mounted by a pair of horizontal pins H6, H8 fastened in the lever 98 and extending through vertical slots I20, I22 in'the plate. Projecting from the inner edge of the plate H4 is a spool-shaped lug I24 provided with a hole through which the shaft I02 passes. This arrangement permits the lever 98 to rotate about the shaft. I02 and yet permits vertical adjustment of the lever relatively to the shaft by reason of the vertical slots in the plate H4. A horizontal pin I26 projects laterally from the upper end of the plate I I4 and enters a hole in the lever I00 (Fig. 1) thereby connecting the two levers in such a manner that rotation of the lever 98 about the shaft I02 will effect a corresponding rotation of the lever I00 which is mounted directly on the shaft I02, as shown in Fig. 4.

In order to rotate the-levers 98 and I 00 into and out of operative position about the shaft I 02 there is formed in the side of the lever 98 a recess I28 (Fig.1) which is arranged to receive a rounded end formed on an upper arm of a bell crank lever I30. The bell crank lever I30 is pivotally mounted on a horizontal. pin I29 carried in the outer end of a laterally extending arm I3I of another lever I32 rotatably mounted on the shaft I02. The lever I32 has a rearwardly extending arm I34 (Fig. 2) which is arranged to engage a lug I36 projecting from the frame and thus to limit rotation of the lever I32 in a clockwise direction. A lower arm I38 of the bell crank lever I30 carries a roll I40 (Fig. 1) which enters a circumferential slot I42 formed in a spoolshaped collar I44 loosely mounted on the shaft I02, this collar also having another circumferential slot I43 formed therein, the function of which will be explained hereinafter. Pivotally secured to the arm- I34 (Fig; 2) is a downwardly extending link I46 the lower end of which is connected to a lever I40 fulcrumed on the shaft 28 and carrying at its outer end a cam roll I50. The roll I50 rideson theperiphery of the cam I04 previously mentioned and is held against the cam by a heavy tension spring I52, the lower end of which is fastened to the fixed shaft 31.

"After the outsole B has been introduced between the. fingers of the g pper members I06,

I 08 and" the clutch has been tripped to rotate the jack and $01! into a substantially vertical "position, the roll I50, which is then on the high part-of the cam I04, rides oi the high portion of the cam and permits the cam lever I48 to descend under the tension or the. spring I52, thereby causing the arm I34 to be lowered until it engages the fixed stop I36. Movement of the 'lever I32 about the shaft I02 causesthe bell crank lever I30, which is carried by the lever I32 and which has its upper arm located in the recess I20, to-rotate the lever 98 about the shaft I02 until the lever assumes the/substantially vertical position shown in Fig. 2. Since the lever I00 is connected to the lever 98 by the horizontal pin-I26 aforementioned, the former will be rotated about its, axis into a similar position.

In placing the outsole between the fingers of the gripping members I06, I08 it is located longitudinally of the machine by means of a gage carried by the toe positioning mechanism pre-.

viously referred to. This toe positioning mechanism operates not only to position the sole longitudinally of the shoe but also to position the toe end of thesole laterally with respect to the toe end of the shoe. It is comprised of two different sets of mechanism, one set being located at each side of the shoe. The mechanism which engages the inner sides of the, shoe and sole (Fig. 8)- is carried by further mechanism which is arranged to remain in a substantially vertical position while the mechanism which engages the outer sides of the shoe and sole is arranged to swing from an outwardly inclined position into a vertical position together with the swinging levers 98 and I00, as will be hereinafter explained. Before the levers 98 and I00,and the swinging portion of the toe positioning mechanism, are swung upwardly into a vertical position, however, the positioning mechanism is moved as a unit longitudinally of the shoe toward the toe end thereof by power-operated mechanism provided for this purpose. This longitudinal movement continues until a shoe engaging abutment carried by the inner positioning mechanism comes into engagement with the toe end of the shoe mounted on the jack, thereby locat- Since the toe positioning mechanism does not' I operate to position the forepart of the sole with respect to the shoe until after means for calipering or measuring the width of the shoe and for positioning the shank and heel portions of the sole transversely of the shoe have been operated, a more detailed description 'of this mechanism and its mode'ot operation will be left until after the measuring and positioning means referred to have been described.

The levers 98 and I each extend upwardly some distance beyond the sole-gripping members I06, I08, and at their upper ends are provided with bosses which extend inwardly and then upwardly. slidably mounted in these L-shaped bosses are shoe engaging members or gages I56, I51 the inner surfaces of which are arranged to contact respectively with the outer side of the shoe in the vicinity of the ball line and the heel breast line, as shown in Fig. l. The mechanism for measuring or calipering the width of the shoe at the ball line operates practically thesame as the mechanism for measuring the shoe at the heel breast line. In order, however, to permit certain adjustments to be made in the mechanism which operates on the heel portion of the shoe which are unnecessary at the forepart, this mechanism is somewhat different in construction from the gage mechanism located at the forepart of the shoe. The gage mechanism at the forepart of the shoe will be described in detail, therefore, before considering the mechanism locate at the heel portion of the shoe.

The upper boss on the lever I00 (Fig. 4), indi-' cated by the numeral I53, has slidably mounted therein the shank portion I54 of the shoe gage I56 previously mentioned, this gage comprising a vertical plate several inches in length and having an inner surface arranged to engage the outer side of the shoe A directly above the sole-gripping member I08. The gage I56 has a horizontal guide pin I58 projecting from its upper portion and arranged to slide in a hole formed in the upwardly projectingportion of the boss I53 so that the gage will be maintained in an upright position during its sliding movement. The shank portion I54 of the gage extends through the boss I53 and carries in its outer end a laterally projecting pin I60 which is engaged by the forked upper end of: a substantially vertical lever I62 fulcrumed on a horizontal pin I64 mounted in a boss formed on the forward side of the lever I00. The lower end of the lever I62 is also forked and engages one end of another pin I66 which extends transversely through a horizontal rod I66. The rod I68 is slidably mounted in a lug I projecting forwardly from the lower end of the lever I00 and the inner end of the pin, as shown in Fig. 4, has a bearing in the body portion of the lever.

The other end of the transverse pin I66 forms a pivot for a toggle link I12 which extends upwardly at an angle of about 40 and has its upper portion bent toward the horizontal. The upper end of the toggle link I12 is pivotally connected by a pin I14 to a boss which extends downwardly from the lower end of a rectangular member I16, hereinafter referred to as the block". The block I16 is cut out at its central portion and is supported in a substantially vertical position by meansofatoggleofwhichthelink I12isapart and a third link located above the toggle, the toggle links forming the means whereby the block is connected to the gages which contact with opposite sides of the shoe. The construction and operation of the block will be explained more fully after the means for maintaining it in a freely floating vertical position has been described.

Projecting forwardly from the rear wall which connects the vertical side walls of the frame I6, and located opposite the outer shoe gage I66, is a boss I16 similar to the boss I66 on the lever I00. slidably mounted in this boss is the shank portion I80 of another shoe-engaging member I82 consisting of a vertical plate adapted to engage the inner side of the shoe substantially at the ball line and opposite the gage I56. The plate I82 is held in position by means of a horizontal pin I83 extending through a hole in the boss directly above the shank portion I80, this shank portion extending through an opening in the wall I0 and having a rounded outer end. A transverse pin I84, mounted in the rear or outer portion of the shank I80, extends between a fork formed at'the upper end of a substantially vertical lever I86 fulcrumed on a pin I88 mounted in a lug projecting rearwardly from the frame. The lower end of the lever I86 also has a fork which engages a pin I90 mounted transversely in a stud or rod I92 which is slidably mounted in a lug I94 projecting from the frame, the other end of the rod being supported in an opening in the frame. Pivotally secured to the opposite end of the pin I90 is the lower end of another toggle link I96 which extends upwardly and forwardly and is connected at its upper end to the pin I'M projecting from the block I 16, the links I96 and :12 forming the toggle which supports the block The shoe gages I56, I82 are moved inwardly toward the shoe by power-operated mechanism, including a cam and mechanism connecting the cam with the block I 16, which lowers the block to straighten the toggle and rotate the vertical levers I62 and I86 in opposite directions about their respective fulcrums, thereby forcing the upper ends of these levers toward the shoe until the side gages contact with the opposite sides 'of the shoe. When one gage contacts with the shoe so that movement of the vertical lever associated therewith is arrested, the toggle link connected to this lever will pivot about the lower end of the lever and cause the block I16 to move downwardly in an are rather than in a vertical direction as the opposite shoe gage moves inwardly toward the shoe. It will be clear from the above that, unless both gages contact simultaneously'with the shoe, the block I 16 will be swung either to the right or to the left as it is loweredby the power-operated mechanism to bring both gages against the shoe.

This action will centralize the block I16 relatively to the shoe or, in other words, will position the block laterally in accordance with the width of the shoe as measured by the shoe gages.

In order that the sole-positioning mechanism may function properly, it is desirable, as stated above, that the block I16 be maintained in a vertical position while the gages are being moved into and out of engagement with the sides of the shoe. Means is provided, therefore, for moving the upper end of the block with its lower end so that it will be maintained in a vertical position irrespective of the amount of movement of the vertical levers I62, I66. To this end there is pivotally mounted on a pin I66 (Fig. 4), carried by cars projecting rearwardly from the frame, a bell-crank-lever 266 having an upper arm to which is connected a downwardly extending link 262. The lower end of the link 202 is pivotally connected to a horizontal arm 204 projecting from the central portion of the lever I86, the arm 264 being about the same length as the upper arm of the bell-crank-lever 266. The lever 266 has a curved arm 206 which extends downwardly for a distance substantially equal to the length of the lower arm of the vertical lever I86. The arm 206 is forked at its lower end and engages a pin 208 which is transversely mounted in a rod 2I0 adapted to slide in a lug 2I2 projecting rearwardly from the frame I0, the forward end of the rod bearing in an opening in the frame.

The other end of the transverse pin 208 is.

stantially vertical position regardless of the positions of. the toggle links I12, I86.

The mechanism for positioning the outsole laterally or widthwise of the shoe bottom at the forepart of the shoe includes the gripping member I08 the shank portion of which is provided near. its outer end with the laterally projecting pin I12. The pin II2 (Fig. 4) is engaged by the forked upper end of a vertical lever 2I8 fulcrumed on a pin 220whichis mounted in a lug 222 formed on the lever I00. The lower arm of the lever 218 is provided with an elongated vertical slot 224. Pivotally secured to the farther side of the lever 218, by means of a headed screw 226 which extends through the slot 224, is another vertical lever 228. The screw 226 is adon ablock 238 (Figs. 1 and 4).

justable in the slot 224 so that the ratio of leverage between the levers 2I8 and 228 may be varied as desired, this variation being accomplished by the following construction.

An angle plate 230- is adjustably secured to the lever I00 about midway of its length by means of a screw 232 passing through a vertical slot 234 in the plate 230. One portion of the angle plate overlies the forward side of the lever I00 (the left-hand side as viewed in Fig. 4) and carries a horizontal pin 236 which extends forwardly and has loosely mounted there The lever 228 is pivotally secured to the block 238 by means of the headed screw 226 which passes through a vertical slot 240 (Fig. 1) in the lever 228, the slot 240 being of the same dimensions as the slot 224 in the lever 218. The lever 228 is fulcrumed at its upper'end on a cylindrical lug 24I. projecting from a rectangular block 242. Threaded horizontally through an upwardly projecting portion of a lug 244 (Fig. 4) formed on the lever I00 is a screw 246, the inner end of which is reduced in size and is rotatably secured in an opening in the block 242. The screw 246 is provided with'a knurled head 248. by which it may be turned to change'the position of the fulcrum 241 of the lever 228. The lower end of' the lever 228 is forked to engage a pin 250 extending transversely through a rod 252 mounted for sliding movement in the lever I00 .The purpose of the'mechanism just described -is'to furnish means for adjusting the sole-gripping member I08 when operating on different styles of shoes. Insome types 'of shoes the positions of the edges of the outsole widthwise-relatively to the widest parts-0f the shoe varies- {somewha't due to the fullness of the=lasts required in such shoes. Because of this, the gripping member I 08 may have to travel a greater or a less distance relatively to the lower end of the lever 228, in order to introduce the outsole in a proper position with respect to the opposite edges of the shoe bottom. When operating on a shoe mounted on a last having a full inner portion, for example, the operator will loosen the screw 226 and move the angle piece 230 into a different vertical position, as determined by the shape of the last upon which the shoe is mounted. In making this adjustment he has changed the ratio of leverage between the upper and lower arms of the lever 2I8. Conse-' quently, when the sole-positioning mechanism is operated in -a manner tobe later described, and

sliding movement is .imparted to the rod 252 to cause the lever 228 to rotate about its pivot 2, the screw 226, being now located a different distance from the fulcrum 220 of the lever 218 so that the length of the lower arm of this lever is changed, will cause the upper end of the lever 2I8 to be moved a greater or a less distance by a given amount of swinging movement of the lever 228, thereby causing the sole-gripping member I08 to be moved inwardly a proper amount for the style of last being utilized. If it is desiredstill further to vary the relation between the levers 2I8. 228, the fulcrum 24I may be moved to a. different position by adjusting the block 242 through the screw 246.

It will be apparent from Fig. 4 that the solegripping member I08 constitutes a part of the positioning mechanism which locates the foreport of the sole relatively to the shoe bottom. The inner member of the sole-positioning mechanism comprises an abutment or gage 256 slidably mounted opposite the gripp member I08 in a lug 262 formed on the frame I 0, the gage 256 being adapted to cooperate with the gripping member to position the forepart of the sole relatively to the'shoe bottom. The gage 256 has a shank portion 260 mounted for sliding movement in the lug 262 and the forward end of the gage projects upwardly and has a vertical surface adapted to engage the inner edge of the sole opposite the gripping member I08. The opposite endof the shank 260 carries a horizontal pm 264 projecting laterally therefrom and extending between the forked upper end of a vertical lever 266 which is substantially the same length as the vtotal length of the interconnected levers 218 and 228 which actuate the member I08.- The lever 266 is fulcrumed on a pin 268 extending through ears on a lug 210 which projects rearwardly from the frame.

The lower end of the lever 266 is forked to 'engage one end of another horizontal pin 21'2 is pivotally connected at its upper end to another 280 is pivotally connectedat'its lower end to the transversepin 250, aforementioned, mounted in the slide rodj252. I

Asviewed in Fig. 4 the toggle links 218, 280 are located rearwardly of the rectangular block I16.

The connecting pin 282 projects laterally from the links 218,280 and carries a roll 284. The-rear side of the block I16 is provided with'a vertical T-shaped slot forming a guideway 286 which extends centrally of the block and in this guideway is mounted for reciprocating movement a slide member 288. The slide member also has a vertical slot 288 formed therein which is located centrally of the slide member and of the block I13, and the roll 284 extends into this vertical slot. The lower portion of the slot 298 is considerably wider than the roll so that the latter is free to move laterally or widthwise thereof. The sides of the slot converge toward the upper portion of the slide so that if the roll 284 is not located centrally thereof as the slide 288 is moved downwardly, the roll will engage one or the other of these converging side walls and will be forced over until its axis coincides with the vertical center line of the slide member. When the roll is in this latter position its axis will also coincide with the vertical center line of the block I18,

since the slide 288 is located centrally of the block. In this way the toggle links 218, 288, which are connected respectively to the levers 268 and 228, and which, through these connections, control the positions of the sole-engaging members I88, 256, are thus centralized relatively to the block I16 and to the shoe gages I56, I82. After the shoe gages I56, I82 have been brought into engagement with the sides of the shoe, the toggle links I12, I88, the parallel link 2I4, and the block I18 will all be located in a predetermined position laterally of the shoe bottom which position is determined by the width of the forepart of the shoe. When the sole-positioning mechanism is operated, therefore, to locate the sole transversely or widthwise of the shoe bottom,

the sole-engaging members I88 and 253 will be moved, through the operation of the slide 288, in such a manner as to position the forepart of the sole in a predetermined transverse position in accordance with the width of the shoe so that the periphery of the sole will extend the desired distance beyond the edge of the shoe bottom at each side of the shoe.

As stated, the gages for measuring or calipering the width of the shoe at the heel portion are operated in substantially the same manner as the gages for measuring the forepart of the shoe. The sole-gripping member I88 (Fig. 2) and the inner gage cooperating therewith are likewise operated similarly to the members I83 and 233 which contact with the forepart of the sole. The two sets of gages at the heel portions of the shoe and sole, however, are carried respectively by movable members located at each side of the shoe.

As already pointed out, the swinging lever 38 at the outer side of the shoe is rotatably mounted on the shaft I82 in -such a manner that it can be adjusted heightwise of the shoe. this adjustment being provided to permit the gages to operate upon shoes having high heels and deeply arched shank portions as well as upon shoes having bottoms which are relatively flat from toeto heel. The shoe gage I31 (Fig. 2) has a shank portion 232 and mounted in the outer end of this portion is a laterally projecting pin 234. The pin 234 is engaged by the fork'ed upper end of ,a vertical-lever 233 pivoted on a pin 233 carried by a boss projecting from the lever 33. The lower end of the lever 233 is also forked to engage another pin 333 transversely mounted in a horizontal rod 332 which slides in an outwardly projecting lug 334 formed on the lower'portion of the lever 33 and is guided at its inner end in the body portion of the lever. The opposite end of the transverse pin 333 forms the pivot for an inwardly and upwardly extending toggle link333 which at its upper end is pivoted at 381 to the lower end of a substantially vertical rectangular block 388 similar in construction and operation to the block I13 of the forepart positioning mechanism. Extending downwardly at an angle from the pivot 381 on the block 388 is another link 3I8 which is pivotally connected at its lower end to a horizontal rod 3 by a pin 3I2 transversely mounted in the rod. The rod 3I4 is slidably mounted in a lug 3I3 projecting rearwardly from the lower end of an elongated vertical plate 3I8 (Fig. 6) 'which is located in a large opening 3I8 formed in the rear wall of the frame I8. The plate 3I8 is carried by a slide member 328 (Figs. 2 and 6) and is arranged for horizontal adjustment along the slide member on a tongue 322 which fits a horizontal groove 323 formed on the rear side of the slide member 328. The slide member 328 is secured to a forwardly projecting yoked portion 32I of the frame by screws 325 located in vertical slots formed in such portion, thus allowing the slide member to be adjusted vertically by means of another tongue and groove arrangement which will be more fully explained hereinafter.

The transverse pin 3I2 in the horizontal rod 3I4 (Fig. 2) is engaged by the forked lower end of a vertical lever 324 pivoted on a pin 326 in 9. lug projecting from the rear side of the vertical plate 3| 8. The upper end of the lever 324 is forked to engage a horizontal pin 328 fastened in-the shank portion 338 of another shoe-engaging member 332 which extends through an upwardly projecting lug formed on the forward side of the plate 3I8. The shoe gage 332 is of the same construction as the othershoe gages, having an elongated plate of substantial length for engaging the inner side of the heel portion of the shoe, this plate being maintained in vertical position by a horizontal guide pin 333 projecting rearwardly from the plate and sliding in a hole in the lug on the plate 3I8.

Slidably mounted in a boss on the plate 3I8,

below the shoe gage 332 and directly opposite the sole-gripping member I83, is a sole gage 334 having a shank 333 which is provided with a horizontal pin 338. The pin is engaged by the forked upper end of a vertical lever 348 fulcrumed on a pin 342 which is carried by a lug on the rear side of the plate 3I8. The lower end of the lever 348 is forked to engage one end of a transverse pin 344 carried by a horizontal rod 343 slidably mounted in a lug projecting from the lower end of the plate 3I8. The other end of the transverse pin 344 forms a pivot for an upwardly inclined toggle link 348 which is pivotally connected at its upper end by a pin 338 to another toggle link 332, the link 332 extending downwardly and at its lower end being pivotally secured to a horizontal rod 334 by a pin 333 which is transversely mounted in the rod, the rod 334 being slidablymounted in a lug formed on the lever 33. The opposite end of the'pin 333 is engaged by the forked lower end of still another vertical lever 331 which is fulcrumed on a cylindrical lug 333 projecting from the side of an adjustable block 333 which is adjusted by means of a horizontal screw 332 threaded through a lug 333 projecting forwardly from the lever 33.

Adjustably secured to the lever 331 is a lever 334 pivoted at 333 on a lug on the lever 33 and having a vertical slot 331 in its lower arm through which a stud 333 passes to secure both levers to a slide block 3" (Fig. 1) mounted on a horizontal pin 333, which pin is carried by an angle plate 318 mounted on the lever 98 and may, by means of the angle plate, be adjusted heightwise relatively to the lever 98 to change the effective length of the lower arm of the lever 364, and thereby to vary the amount of swinging movement'imparted to the upper end of this lever in the manner already described in connection with tl e levers 2I8 and 228. The upper end of the lever 364 is forked to engage the pin H8 previously mentioned as being mounted transversely in the shank portion of the solegripping member I86. The pin 358 (Fig. 2), which connects the toggle links 348, 352, projects laterally beyond the links and carries a roll 312 which enters a vertical slot in a slide member (not shown) mounted for reciprocative movement in the vertical block 388. The arrangement of the block, slide, and the means for supporting these members in an operative position need not be described in detail since it is practically the same as the mechanism previously described for supporting the block I16 and slide 288 which actuate the gages at the forepart of the shoe. The power-operated means referred to for bringing the various sole and shoe gages into engagement respectively with the sole and shoe, and for causing the sole gages to operate to position the sole laterally of the shoe bottom will next be described.

The toggle link I12 (Fig. 4), which is pivoted at I14 to the block I16, has pivotally secured to its upper portion, adjacent to the block I16, a downwardly extending link 314. The lower end of this link 314 is provided with a vertical slot 315 through which passes a horizontal rod 316 (Figs. 4 and 7) One end of the rod 316 is mounted in the outer extremity of an arm 318 and the opposite end is mounted in the upper arm of a bell-crank-lever 388 (Fig. 7), the arm 318 and thelever 388 being rotatably mounted on a fixed shaft 382 carried by a pair of lugs 384, 386 projecting forwardly from the frame I8. Fixed on opposite ends of the shaft 382, outside the lugs 384, 386, are downwardly projecting stationary arms 3!, 383, which carry at their lower ends a rod 385. The toggle links 218, 288, which are connected to the gages that operate on the forepart of the sole and which carry the roll 284, have secured to the link 288 a substantially vertical link 388 (Figs. 4 and 7), which is also provided at its lower end with a vertical slot similar to the slot 315 and through which the rod 316 passes. The vertical links 314 and 388 are held downwardly so that the rod 316 will normally be positioned at the upper ends of the vertical slots by means of tension springs 381, 389, which extend from the lower ends of the links to the rod 385, as shown in Fig. 4.

The toggle links 386 and 3l8 (Fig. 2), which actuate the shoe gages located at the heel por tion of the shoe, have connected thereto a downwardly extending link 898 (best shown in Fig. 7) which is provided in its lower end with a vertical slot through which the rod 316 passes and the upper pair of links 348, 352, which carry the roll 312, are likewise provided with a vertical link 392 having a slot through which the rod 316 passcs. Each of these vertical links is urged downwardly so .that the rod is normally positioned at the tops of the slots by means of tension springs extending between the lower ends of the links and the rod 385, these springs being indicated in Fig. '7 by the numerals 38l and 393. The lower arm of the bell-crank-lever 388 (Fig. 2) is pivotally connected by an intermediatelink 394 to an upwardly extending arm of a large bell-crank-lever 386 fulcrumed on the shaft '28 and having a lower arm 391 provided with a roll 398. The roll 398 rides on the periphery of a cam 488 keyed to the cam shaft 34 and a tension spring 482, connected at one end to the bellcrank-lever 396 and at the other end to the fixed shaft 31, acts to hold the roll against the cam.

After the shoe has been mounted on the jack and swung downwardly into an upright position and the sole has been carried up and introduced between the shoe and the pad by the action of the cams 32 and I84, and after an interval has elapsed during which other mechanism yet to be described is operating, a depression on the cam 488 permits the roll 398 to descend under the influence of the spring 482 to rotate the bell-crank-lever 396 about the shaft 28 in a clockwise direction as viewed in Fig. 2. Rotation of the lever 396 causes the bellcrank-lever 388 to rotate in an opposite direction to lower the horizontal rod 316 in the vertical slots of the several vertical links. As the rod descends the springs connected to. these links will pull the links downwardly thereby lowering the rectangular blocks I16 and 308 and moving the two sets of toggle links connected to the blocks into more nearly straightened positions. This movement of the toggle links causes the vertical levers which are connected at their upper ends to the various shoe-engaging and sole-positioning gages to be rotated more or less about their respective pivots until the shoe gages contact yieldingly with the opposite sides of the shoe and the inner sole gages contact with the inner edge of the sole. In bringing the shoe gages against the side of the shoe, the blocks I15, 388 will not only be moved downwardly but, as explained above, will also be moved laterally if necessary until they are located approximately centrally of the shoe bottom. The rolls 284 and 312, which are then located in the wide portions of the vertical slots in the slide members, and which are therefore free to move widthwise of the slots, may be moved either to the right or to the left by their respective toggles depending upon the distances which the sole-engaging or gripping members have to travel before automatically positions the toe end of the sole which are arranged to engage the toe ends of the shoe and sole and to locate these portions relatively to each other as the shoe gages and sole gages are locating the opposite sides of the sole relatively to the shoe. The positioning fingers or gages which engage the sole and shoe at their outer sides, that is, the sides nearest the operator, are arranged to swing outwardly (Fig. 8)

away from operative position together with the shoe gages and sole-gripping members which engage the shoe and sole at their outer sides and which, as described, swing into and out of operative position about the shaft I02. The swinging movement of the outer toe gages is accomplished by rotatably mounting the mechanism which supports these gages on the shaft I02 and by having this supporting mechanism extend through an opening or guideway in a bracket 406 (Figs. 1 and 8) extending laterally from the side of the swinging lever I00 which carries the outer shoe gage I56 and gripping member I08. As the lever I00 is swung toward and away from operative position by reason of its connection at I26 with the lever 98, the bracket 406 will carry the mechanism which supports the toe-positioning gages forwardly and rearwardly with these levers.

The bracket 406 extends toward the left, as viewed in Fig. 1, and is supported at its outer end by a downwardly extending arm 408 loosely mounted on the shaft I02. On the farther side of the bracket is a projection 401 (Fig. 8) provided with a vertical guideway 0 through which extends the upper portion of another bracket or arm 2 loosely mounted on the shaft I02 and provided with a pair of cylindrical bosses 409 and 4 located respectively below and above the bracket 406. The portion of the bracket 4 I 2 which is located within the guideway 4I0 has formed on opposite sides thereof a pair of projections or lugs 4I3 which slidably engage the side walls of the guideway and thus prevent the bracket from moving laterally therein. Mounted for sliding movement in the bosses 409, 4 is a shaft 4I4 which extends some distance beyond the upper boss M I and has secured to its upper end a carrier member 6. The carrier member 4I6 has a projection formed thereon which extends upwardly and is bored lengthwise to receive a stationary rod 4I8 which is pinned in the carrier and projects upwardly beyond the carrier member, the rod having a plurality of laterally extendingfingers or gages mounted thereon and arrangedto engage the toe portions of the shoe and sole substantially at their tip lines.

The lower finger or gage 420 is pivotally mounted on the rod 8 and extends forwardly toward the shoe. This finger is provided with an enlarged end for engaging the edge face of the outsole substantially at the tip line when the positioning mechanism is in operative position. A rearwardly extending arm 422 (Figs. 1 and 9) of the finger 420 is provided with a downwardly extending portion having at its inner side a ground vertical surface 424 which is disposed at an angle of about 25 or 30 degrees to the longitudinal center line of the finger and which diverges outwardly toward the rear end of the arm. The gage member or finger mounted next above the finger 420 is pinned to the rod 4 I 8 and comprises a shorter arm 426 which projects inwardly relatively to the finger 420 and then extends forwardly toward the sole. This arm 426 has formed on its outer end a downwardly projecting lug 428 which 15 arranged to engage the tip end of the sole to locate it longitudinally of the shoe.

Pivotally mounted at the upper end of the rod 8 is a shoe-engaging finger 430 comprising a forwardly extending arm at the outer end of which is formed a downwardly projecting portion 432 of considerable length which is adapted to engage the toe portion of the shoe substantially at the tip line. The finger 430 has another arm 434 projecting rearwardly or toward the left, as viewed in Fig. 1, and having formed on its inner side an upstanding lug 436. An inner surface 431 (Fig. 9) of the lug 436 diverges outwardly toward the rear of the arm 434 at substantially the same angle as the inner surface on the rear arm of the finger 420.

The carrier member 6 is provided with a substantially horizontal arm 4I5 which extends toward the lever I00 and is provided at its end with a laterally projecting boss 4 I I. The boss 4 I1 carries a horizontal pin 439 upon which is pivotally mounted a connecting member or coupling 438. An outer cylindrical portion of the coupling 438 is perpendicular to the pin 439 and has an opening in which is slidably mounted a rod 440 which extends for some distance beyond the opening at either end of the coupling. The portion of the rod 440 which extends toward the lever I00, as viewed in Fig. 1, is secured in an elongated bushing 442 the inner end of which is provided with an upstanding lug 443. A pin 445 passing through the lug 443 pivotally secures the bushing to a boss on the inner side of the swinging lever I00. The bushing 442 is also provided at its under side with a circular lug 441 by means of which the bushing is connected to adjusting mechanism to be described later.

The positioning fingers or gages which contact with the inner sides of the sole and shoe and which, unlike the gage fingers just described, always remain in a vertical position, are carried by a member 444 (Fig. 8) mounted for horizontal sliding movement in a T-shaped slot 446 formed in the central portion of a projection or lug 448 which projects forwardly from the rear wall of the frame I0. The sliding member 444 is provided with an upstanding arm 450 at the upper end of which is a horizontal boss having a vertical hole formed therein. Mounted for sliding movement in-this hole is a shaft 452, the lower end of which passes through a vertical opening in another horizontal boss 453 located at the central portion of the slide member 444. Secured on the upper end of the shaft 452 is a carrier member 454 having an arm 456 which projects forwardly, as viewed in Fig. 8, and which has pivotally mounted thereon a. connecting member or coupling 458 similar to the coupling 438 on the member 4| 6. The coupling 450 has slidably mounted therein a rod 430 which extends for some distance beyond the ends of the coupling. The portion of the rod 460 which extends forwardly or toward the shoe is fastened in an elongated bushing 462 provided at its inner end with an upwardly projecting lug 46I which is pivotally connected to a boss on the frame by means of a pin 464. The mechanism which connects the carrier member 454 to the frame I0 is practically the same in construction as the corresponding mechanism which connects the outer half of the toe-positioning means to the lever I00 and these mechanisms provide the means through which a vertical adjustment of the positicning fingers is obtained.

The carrier member 454 also has an upwardly projecting portion 465 which is bored vertically and has secured therein a rod 466 the upper portion of which projects for a considerable distance above the member 454 and provides supporting means for a plurality of positioning fingers arranged to engage the inner sides of the sole and shoe opposite the gage fingers 420, 430. A lower or sole-engaging finger 468 (Figs. 8 and 9), similar in construction to the finger 420, has a rearwardly projecting arm 469 provided with a ground surface 410 which is disposed at an angle of about
