80 Claims.

This invention relates to upper-shaping machines and is herein illustrated in its application to machines for shaping prewelt uppers. It is to be understood, however, that the invention is not limited to machines which operate on prewelt uppers, the invention, in certain aspects thereof, being applicable to upper-shaping machines generally,

It is an object of the present invention to provide a machine for shaping prewelt uppers without the aid of lasts, thus eifecting an economy in prewelt shoe manufacture and expediting the upper-shaping operation by obviating the handling of lasts and their insertion into the upper. It is a further object of the invention to perform the usual overwiping operation to position the welt for attachment to an outsole while the upper is so positioned on an inner form that it is under no tension either widthwise or lengthwise of the upper and, consequently, no resistance is oifered to the overwiping operation and the welted margin is wiped in quickly and easily without exerting any strain against the welt-attaching seam.

With the above objects in view, the present invention in one aspect thereof comprises an upper-shaping machine having an upper-shaping expander, Wiping means herein illustrated as a wiper plate, means for effecting relative movement of said expander and said wiper plate to wipe the bottom margin of an upper in over said expander, and means for actuating said expander to shape the overwiped upper. The illustrated expander comprises an inner upper-shaping plate over which the wiper plate wipes the bottom margin of the upper, and an inner uppershaping mold which in the illustrated machine moves relatively to the upper-shaping plate to expand and shape the upper.

The illustrated inner plate is made bilaterally symmetrical in shape in order to adapt it to operate on both right and left uppers, the peripheral contour of the plate being such that it imparts a preliminary shape to the upper which closely approximates the final shape to be imparted to said means effecting a relative movement of the mold and the inner upper-shaping plate heightwise of the upper to expand the upper, that is, to increase its girth, and means for effecting relative movement of the mold and said plate lengthwise of the upper to bulge the upper, that is, to extend it toewardly to increase the peripheral dimension of that portion of the upper on,

which the mold operates. To provide for lengthwise movement of the mold, said mold is movably mounted in a carrier and an actuator is provided for moving the mold longitudinally in said carrier. The heightwise movement of the mold is effected by an actuator which operates on the carrier to move it heightwise of the upper. In the illustrated machine,,in accordance with a further feature of the invention, the heightwise and lengthwise movements of the mold occur substantially simultaneously, a common operating means herein illustrated as a hand lever being provided for simultaneously advancing said actuators.

In order to hold the bottom margin of an upper against displacement from its overwiped position on the inner upper-shaping plate during the operation of the mold, the illustrated machine, in accordance with a further feature of the invention, is provided with means herein illustrated as presser bars for causing the wiper to grip the margin of the upper against said plate upon the completion of the wiping operation. To facilitate the operation of the machine, a common actuator is provided for the operation of the wiper and the presser bars, said actuator being connected to the wiper by means including connections which, upon completion of the operation of the wiper, are rendered ineffective to advance the wiper further, while permitting the actuator to advance said presser bars relatively to the wiper to perform their appointed function.

In accordance with a further feature of the invention, the illustrated machine is provided with means for yieldingly supporting .a prewelt upper by engagement within the welt crease, means herein illustrated as a welt-engaging member for locating the welted margin in a predetermined heightwise position, the upper being held in said predetermined position for the overwiping operation by the gripping action of the inner and outer forms. The illustrated welt-engaging member is constructed and arranged to engage the out-sole-attaching surface of the welt and to bring the welted margin into a position of registration with the edge face of the inner uppershaping form to arrange the welted margin for the overwi-ping operation.

In accordance with a further feature of the invention, the welted margin of the upper after being positioned heightwise thereof by the locating means above described, is secured in such heightwise position by being gripped between the inner upper-shaping plate and means herein illustrated as a pair of complementally-shaped outer forms constructed and arranged to cooperate with said plate to grip the upper and hold it in its predetermined position. trated machine, the inner upper-shaping plate and the outer forms are so positioned heightwise of the upper relatively to said locating means that a uniform width of overwiping margin ,is provided.

After the overwiping margin has been wiped In the illus- W in over the inner upper-shaving plate and gripped against said plate by the operation of the presser bars on the wiper plate, the outer forms are retracted to provide clearance for the bulging operation of the mold. In the illustrated machine, the retraction of the outer forms is effected by means operated by the wiper actuator during the latter part of the advancement of the presser bars.

To insure a uniform wiping of the welted margin of a prewelt upper inwardly over the uppershaping plate, the illustrated machine, in accordance with a further feature of the invention, is provided with means for conforming the welt to the peripheral contour of said plate to position the welted margin for the overwiping operation, said means being herein illustrated 'as a welt-conforming plate constructed and arranged to engage the outer edge face of the welt after the wiper plate has engaged the corners of the toe portion of the welted margin and brought the welt into sole-attaching position. The welt-engaging edge face of said welt-conforming plate is so constructed that when said plate is in its advanced or welt-conforming position, its weltengaging edge face is uniformly spaced from the edge face of the inner upper-shaking plate. The illustrated welt-conforming plate is carried by the wiper plate and moves with the wiper into welt-engaging position in which position it is yieldingly held while the wiper advances relatively to said welt-conforming plate to complete its overwiping movement.

In the illustrated machine, a wiper actuator operates alternately to advance and to retract the wiper, means being provided for shifting the connections from the actuator to the wiper to effect a reversal of the wiper movement. The illustrated mechanism includes a pair of links which operate alternately at opposite ends of a rocker and means operating automatically upon the idle stroke of the actuator to shift said links relatively to the rocker.

These and other features of the invention will now be described with reference to the accompanying drawings and pointed out in the appended claims.

The illustrated machine is designed to operate on the uppers of prewelt shoes in the range of the smaller childrens sizes, such shoes being characterized by a rather pronounced square tie having sharply curved corner portions which present a difficult problem in the handling of the welted margin in the upper-shaping operation. The machine illustrated in the drawings is particularly adapted to handle with ease said sharply curved portions of the upper and to arrange those portions of the welt for the subsequent shoemaking operations.

In the illustrated machine, the toe portion of a prewelt upper is initially supported in inverted position on the upturned end portion of a thin resilient plate I08 (Fig. 3) which supports the upper by the engagement of its upper edge within the welt crease. This plate is yieldingly mounted to permit the toe portion of the upper to be moved downwardly into a predetermined heightwise position by a member 36 which operates against the welt. This member positions the upper heightwise thereof in predetermined relation to an upper gripping means comprising a pair of forms 88 (Fig. 4), made of Bakelite or other suitable non-corrosive material, constructed and arranged to engage the outer surface of the toe portion of the upper along a line parallel to the welt seam and an r inner form or plate 86 arranged to engage the v inner surface of the upper at a position heightwise of the upper corresponding to the position of the outer forms, said inner form having an edge contour complemental to the contour defined by attaching face of the welt. It will be understood that the upper-gripping members in addition to their functions of gripping the upper and supporting the welted margin during the wiping operation also establish a predetermined peripheral contour of the toe portion of the upper corresponding generally to the peripheral contour of an outsole suitable for attachment to the upper. The wiper plate is so constructed and arranged that its first points of contact with the welt are at the sharply curved portions at opposite sides of the toe portion of the upper. The engagement of the wiper with the sharply curved portions of the welt bends the welted margin inwardly over the margin of the inner upper-shaping plate and arranges the toe portion of the welt in a horizontal position in which the outer edge face of the welt registers with the welt-engaging edge face of a weltconforming plate I38 (Fig. 6) which advances with the wiper and engages the welt immediately after the wiper has bent the welt into horizontal position, as shown in Fig. 6. That portion of the welt extending heelwardly from the toe .end of the upper is held in horizontal position by the operator to receive the welt-conforming plate. The illustrated welt-conforming plate has a welt-engaging edge face which is so shaped that in the advanced position of said plate, said edge face is spaced uniformly from the edge face of the inner upper-gripping plate 86. The welt-conforming plate is positioned adjacent to the under surface of the wiper plate and. advances with the wiper plate into welt-engaging position. By its engagement with the outer edge face of the welt, the welt-conforming plate determines the overwiped position of the welted margin and insures a uniform disposition of the welt with relation to the inner plate 86 over which the welted margin is wiped. The advancement of the welt-conforming plate is arrested by the welt itself, the extent of overwipe of the upper being determined by the width of upper margin projecting upwardly from the upper gripping forms. After the welt conforming plate is arrested, the wiper plate continues its advancement almost to the ball portion of the shoe and, in the course of this movement, presses the welted margin downwardly against the margin of the inner form. Upon completion of the advancement of the wi per plate downward pressure is applied thereto to cause it to grip the welted margin against the margin of the inner form and hold it against displacement from its overwiped position thereon during the subsequent upper-molding operation.

For performing the upper-molding operation, a suitably shaped form or mold 236 (Fig. 3), pcsitioned adjacent to the under surface of the inner plate 86 moves downwardly to expand the upper heightvvise thereof and toewardly to create a well-defined bulge in the toe end of the upper. Prior to the movement of said mold, the outer upper-gripping forms 88 move away from the upper in order not to restrict the toeward movement of the mold.

In Fig. 2 there are illustrated two embodiments of the invention, one being the toe-molding machine hereinafter specifically described, and the other, which is mounted in the same machine head, being a machine for molding the heel portion of the upper. The heel-molding machine differs from the toe-molding machine only in that the outer forms extend vertically substantially the full height of the upper and also in that the inner form does not have the upper-expanding and upper-bulging action of the toe-shaping mold member. In other respects; the functions and the mechanism of the heel end molding machine are substantially the same as in the toe-molding machine. Accordingly, th heel end molding machine is not hereinafter specifically described,-a specific description of the toe-molding machine being considered sufficient to enable persons skilled in the art to comprehend the construction and operation of both machines.

Referring now to Fig. 1, the illustrated toeforming machine is mounted in a machine head supported by a standard 22, the forward portion of the machine head having forwardly extending parallel vertical walls 24 between which the wiper and other operating parts are mounted. Parallel arms 26 extend forwardly from the Walls 24 and provide the forward portions of a guideway in which the mechanism above-referred to is mounted. In the upper-portions of the walls 24 are bearings for a cross-shaft 28 to which is secured a carrier or block 30 which carries those portions of the upper-forming mechanism operating within the toe portion of the upper. Mounted between inward extensions 32 (Fig. 2) of the upper portions of the walls 24 are parallel vertical arms 34 which carry at their lower ends an upper-positioning plate 36 which acts against the welt and upper to position the upper heightwise' thereof relatively to the operating mechanism (Fig. 7). As shown in Fig. .1, the arms 34 have vertical slots 38 through which the crossshaft 28 extends, the engagement of said shaft with the parallel walls of the slot serving to determine the path of movement of said plate 36. The block 30 and the plate 36 are actuated by a treadle 40 fulcrumed at 42 in the base of the machine standard. For imparting the downward movement of the treadle to the plate 36 a link 44 extends upwardly from the treadle to an arm 45 of a three-armed lever, the arm 46 of which is connected by a link 48 to the rear end of an arm 50 secured to a cross-shaft 52 journaled in vertical arms 53 (Fig. 7). Extending forwardly from the cross-shaft 52 are arms 55 (Fig. 2) pivoted at their forward ends to the upper end portions of the arms 34 which carry the plate 36. The plate 36 is normally held in retracted posi tion by a spring 56 which acts on the arm 50. For swinging the block 30 and the upper-shaping mechanism mounted thereon from the position of said assembly illustrated in Fig. 1 downwardly and rearwardly into the toe portion of a supported upper, the arm 5'! of the three-armed lever is pivotally connected to a vertical link 58, the upper portion of which has a pin-and-slot connection to an arm 60 secured to the shaft 28. To time the downward movement of the plate 36 to terminate just prior to the completion of the advancement of the block 30 the link 48 is slotted at 49 to provide a predetermined lost motion of the arm 46. A spring 62 connected to the arm 68 normally holds said upper-shaping assembly in its retracted position, illustrated in Fig. 1. Inasmuch as it is necessary to return the plate 36 to its retracted position at an early stage in the machine cycle to provide clearance for the operation of certain parts hereinafter described, means is provided "for locking the block 30 and the upper-forming assembly mounted thereon in their advanced position, illustrated in Fig. 8,

and after said assembly has been so locked the.

treadle 40 is permitted to return to its elevated position while the spring 56 retracts the plate 36. The upward movement of the treadle will of course move the link 58 upwardly, the slot in said link being long enough to accommodate the upstroke of the treadle. Referring to Fig. 8, the mechanism for locking the upper-forming assembly in its advanced position comprises a pawl 64 constructed and arranged for locking engagement with a segmental plate 66 secured to the right end of the shaft 28 and provided with a notch 68 which receives the downwardly extending tooth of the pawl. In order to prevent the segmental plate 66 from swinging beyond the point of registration of the notch and the pawl, a segmental plate I2 (Fig. 3) is secured to the left end of the shaft 28 and arranged to register with a fixed stop member I4 which acts against lugs I6 and I8 on the segmental plate. The engagement of the lug I8 with the stop member arrests the advancement of the upper-forming assembly with the pawl 64 in registration with the notch 68 in the segmental plate 66. The engagement of the lug I6 with the stop member determines the retracted position of the upper-forming assembly illustrated in Fig. 3. Referring to Fig. 7, the plate 36 positions the toe portion of the upper heightwise thereof in the machine by engagement of its bottom surface 80 with the adjacent edge faces of the welt and upper of a prewelt upper such, forexample, as the upper 82, partially illustrated in Fig. '7. The plate 36 also serves to bring the welted margin into registration with the upper-shaping forms hereinafter described, this function being performed by the engagement of a beveled surface 84 of the plate 36 with the welted margin of the upper during the downward movement of the plate, said beveled surface acting to bend the welted margin inwardly from its initial outspread position into its position illustrated in Fig. '7. It will be understood that the beveled surface 84 has a curvature complemental to the curvature desired for the toe portion of the welted margin of the upper at the intermediate station in the upper-shaping operation illustrated in Fig. 7. The plate 36 positions the welted margin at the toe portion of the upper at a uniform elevation above the inner uppershaping plate 86, thus providing an overwiping margin of uniform and predetermined width.

The plate 86 has the general peripheral contour of the forepart of a last bottom, but is made bilaterally symmetrical, as shown in Fig. 6, in order to permit its operation on both left and right shoes without adjustment. It will be understood that since the shoe in its final form is not symmetrical in shape at its toe portion, the upper must be further shaped, after it has been operated upon by the illustrated machine, but the further shaping required to put the upper into its final form is relatively slight and can be readily accomplished after the upper has been initially shaped in the present machine. Referring to Fig. 3, the plate 86 is secured to the forward surface of the block 30 by screws 90 which accurately locate the plate with relation to the outer forms 88. Referring to Fig. 4, the outer forms 88 are pivotally mounted on a carrier plate 92, upon the headed screws 94 positioned at the outer corner portions of said forms. In their rest position the outer forms 88 are arranged, as shown in Fig. 4, with their forward end portions abutting stop screws 96 carried by the plate 92. In this position the separation of the forward portions of the outer forms is somewhat greater than the width of the corresponding portion of the plate 86 and consequently said plate, during its advancement into the upper will first grip the central portion of the toe end of the upper against the end portions of the outer forms 88 and further advancement of the plate 86 thereafter will by pressure of its toe end against the outer forms swing the forward portions of the forms inwardly to cause the upper to be gripped between the plate 86 and the outer forms along the entire length of their gripping surfaces. As shown in Figs. 8 and 12, the work-engaging portions of the outer forms 88 extend upwardly from each form, the outer surface of said upward extension being beveled to provide a narrow upper edge portion which facilitates the initial positioning of the welted margin of the upper upon said outer form. The carrier plate 92 is slidably mounted in a suitable guideway provided by the walls 24 (Fig. 2) and the arms 26 and inward extensions 93 which underlie and support said carrier plate. The carrier plate is urged forwardly in its guideway by a spring 98 (Fig. 8) one end of which is secured to a bracket I and the other end of whichis anchored to the machine frame. When the machine is at rest, the carrier plate 92 is positioned by the engagement of a stop screw I02 in the bracket I00 with a fixed abutment I04. The upper-engaging plate 86 forces the carrier plate rearwardly slightly into its position illustrated in Fig. 8 and causes the spring 98' to exert uppergripping pressure against the outer forms 88. The gripping pressure thus exerted is sufficient to prevent any heightwise displacement of the upper by the action of the wiper plate.

In order to asist the operator in positioning the welted margin at the toe end of the upper at an elevation such that it will be engaged and moved downwardly by the operation of the plate 36, a resilient toe-supporting plate I08 (Fig. 3) is supported by the carrier plate 92 and is so positioned that its upturned end portion resting on the rounded edges of the outer forms 88 supports the toe portion of the upper by engagement within the welt crease (Fig. '7). The rear portion of the plate I88 is fixed in a block II'0 (Fig. 5) which is swivelled on a plate IIZ pivotally mounted on a headed screw II 4 projecting upwardly from the carrier plate 92, the plate I08 being urged forwardly into its upper-supporting position by a spring I'I6 operating on the plate II2. It will be understood that during the downward movement of the plate 36, the plate I08 is forced downwardly and rearwardly upon the beveled surfaces of the outer forms 88 against the tension of said spring I I6. In order to withdraw the upturned end portion of the plate I08 into a position in which it will not obstruct the operation of the wiper and other operating parts, the plate I I2 is swung in a clockwise direction, as seen in Fig.5, by the operation of a pin II8 extending downwardly from the welt-conforming plate, hereinafter referred to, against an extension I20 of the plate II2 during the forward movement of said welt-conforming plate. To facilitate the vertical movement of the workengaging end portion of the plate I08, the adjacent end portions of the outer forms 88 are recessed to provide continuous beveled surfaces I22 on which said plate may move, the end portion of said plate being held against widthwise movement between shoulders I24 (Fig. 5) which terminate the beveled surfaces I22.

For wiping the welted margin inwardly over the margin of the inner plate 86, the illustrated machine is provided with a wiper plate I26 (Fig. 3) removably secured by headed screws I28 in a. recess in the bottom of a wiper carrier I36. Referring to Fig. 9, the wiper carrier moves longitudinally over two pairs of rolls I32 and a third pair of rolls I36 slightly ofiset upwardly with relation to the rolls I32, all of said rolls being. mounted to turn on headed pins I35 (Fig. 4) extending through the walls 24. Ihe olls I34 cause the wiper carrier to advance in a downwardly inclined direction which enables the wiper I26 more effectively to bend the sharply curved corner portions at the toe end of the welted margin in over the margin of the plate 86. After the wiper has overwiped said corner portions, the roll-engaging plates I31 on the underside of the wiper carrier I36 ride off the rolls I34 and the wiper continues its advancement in a generally horizontal position. As the wiper proceeds, the welt I36, being slightly higher than the rollsIs32 causes the plates I31 to rise slightly above said rolls and the wiper is thereafter positioned solely by its engagement with the welt. The connec-,

tions between the wiper carrier and its operating means, hereinafter described, afford a limited. freedom of movement of the wiper assembly about axes extending both lengthwise and widthwise of the supported upper to permit the wiper to be so positioned by its contact with the welt that it presses uniformly against the opposite side portions and the end portion of the welted margin of the upper. It will also be understood that since the wiper is supported solely by the welt during the greater part of its wiping movement, downward pressure applied to the wiper by means hereinafter described is effective to press the welted margin of the upper 1 cessed to provide an edge face I46 which, inthe operative position of said plate illustrated in. Fig. 6, is uniformly spaced from the edge face I'4I of the plate 86. The welt-conforming plate is positioned adjacentto the bottom surface of the wiper carrier I68 (Fig. 3) and advances with the wiper carrier in the position relative to said carrier illustrated in Fig. 6. The welt-conforming plate I38 engagesthe outer edge face of the welt after the wiper has overwiped the welted margin at the corners of the toe end of the upper, Fi 6 illustrating the relative position of the welt, the wiper and the welt-conforming plate at the instant the welt-conforming plate comes intocontact with the welt. As the wiper continues to advance from this position, the welt-conforming plate I38 remains at rest and is held in weltengaging position by the tension of a light spring hereinafter identified. Referring to Figs. 3, 4, and 6, the illustrated welt-conforming plate carried by headed screws Hi2 extending upwardly into the wiper carrier, said screws being positioned within recesses I44 at opposite sides of the welt-conforming plate and the heads of said screws extending in under rabbetted portions I l-5 at opposite sides of the plate and providing means for supporting the plate and positioning it widthwise thereof. Extending rearwardly from the plate I33 is an arm I66 (Fig. 3) having a downwardly extending pin I68 which carries the rear end of a tension spring t5!) the forward opposite sides of the block 38.

end of which is anchored to the machine head- The spring I58 normally holds the wiper carrier and the welt-conforming plate in their relative position illustrated in Fig. 6 with the screws I62. in. engagement with the rear end walls of the recesses I64.

For applying a relatively light downward pressure to the wiper during its overwiping movement, a pair of headed pins I68 are slidably mounted in vertical bores in the extensions 32 (Fig.2) of the walls 26 and are pressed downwardly against rails I21 on the wiper carrier I38 by springs I16 (Fig. 3) surrounding the lower portions of said pins and mounted in counterbores in said extensions 32. When the wipers are retracted, the pins I68 are so positioned vertically by stop nuts H2 at their upper end portions that during the advancement of the wiper the headed ends of said pins are engaged and lifted by beveled end portions of said rails I21. For pressing the wiper in its advanced. position downwardly against the welt to hold the overwiper margin against displacement on the plate 3.6, parallel presser bars I52 (Figs. 3 and 4) are slidably mounted in longitudinal grooves in the wiper carrier I30 and are held in said grooves by headed screws I354 extending through slots I56 in the presser bars. After the wiper comes to restat the limit of its advancement, the presser bars I62 continue to advance into their position illustrated in Fig. 10 in which position beveled. surfaces I56 at the forward end portions of the presser bars have engaged .rolls I66 which yieldingly press the forward portions of said bars downwardly against the opposite side portions of the wiper carrier. As shown in Fig. 2, the rolls I66 are mounted at opposite ends of a cross-shaft I62, being positioned adjacent to the As shown in Fig. 3, the shaft I62 is mounted in slots I64 in the block 38 and is yieldingly urged downwardly by a spring I 66 mounted in a bore in said block and held under compression by a headless screw I-6'i. The shaft I62 is free t5 rock about the lower end of the spring I66 in ordertoenable the rolls I66 to apply uniform pressure to opposite sides of .the wiper regardless of variations in thickness of the welted margin at opposite sides of the upper. The downward pressure thus imparted to the wiper causes the wiper to grip the welted margin of the upper firmly against the margin of the. plate 86 and to hold the welted margin against displacement during the subsequent upper-expanding and bulging operations. In order to insure a positive gripping of the welted margin against the plate 86 by the downward pressure of the wiper the edge portion of the plate 86 is provided with a small upwardly extending bead I74 which is pressed into the inner surface of the upper when the final pressure is applied to the wiper, as shown in Figs. 3 and 10.

For actuating the wiper I26- together with the welt-conforming plate I38 and the wiper presser bars I52, a treadle I16 (Fig. '1) is pivotally mounted in the base of the machine and connected by mechanism, now to be described, to an arm "8 fixed to a'shaft I 88 in the machine head'and pivotally connected to the rearmostof a pair of toggle links I82 I84 (Fig. 3) constructed and arranged to connected the upper end of the arm I78 to the rear portion of the wiper carrier I38. The treadle operates through mecha nism so constructed and arranged that downward movement thereof alternately advances and retracts the wiper and associated parts. This mechanism comprises a crossarm I86 (Fig. 13) fixed to the shaft I80 and provided at its opposite ends with pins I88 and I90 constructed and arranged to be engaged alternately by hooks I92 and I94 at the upper ends of links I96 pivoted at their lower ends to a pin I91 in the treadle I16. The hooks I92 and I94 are held uniformly spaced from each other by a link I98 which is of such a length that the space between the hooks is slightly less than the space between the pins I88 and ISO on the crossarm I86. Thus, when the hook I92 is acting on the pin I88 to swing the arm I86 in a counterclockwise direction, as seen in Fig. 13, the pin I90 moves upwardly without engaging the hook I94 which in this case is inoperative. In order that the next operation of the treadle I16 may swing the crossarm I86 in a clockwise direction, mechanism is provided for automatically shifting the interconnected hooks I92 and I94 so that the hook I94 will engage the pin I90. This mechanism comprises a bellcrank lever 200 freely mounted at its elbow on the shaft I80 and provided at its lower end with a wedge-shaped stop member 202 which engages alternately pins 204 and 205 projecting from the lower portions of the hooks. The pin-engaging edge faces 201 of the stop member 202 are arranged at such an angle to the downwardly extending arm of the bell-crank lever 200 that in their respective pin-engaging positions they extend substantially vertically and, consequently, the bell-crank lever receives no appreciable turning movement from the

pins

204 and 205 during the downward movement of the hooks I92 and I94. It will be understood that the length of the pin-engaging surfaces 201 corresponds generally to the relative vertical movement of the bell-crank lever and the hooks. For causing the bell-crank lever to swing with the crossarm I86, 2, pair of

pins

206 and 208 are mounted in longitudinal alinement with each other in bearings in a head 2I0 at the end of the short arm of the bellcrank lever 200 and arrangedto engag an extension of the pin I90 at the right end of the crossarm I85. The heads of the

pins

205 and 208 are connected together by a tension spring 2I2 which normally holds the horizontal arm of the bell-crank lever in registration with the arm I86. As the treadle is operated to swing the crossarm I86 in a counterclockwise direction, the stop member 202 on the bell-crank lever swings to the right as seen in Fig. 13 until it is arrested by engagement with the pin 205 on the hook I94. This occurs at an intermediate stage in the advancement of the arm I18. During the continued operation of said arm,'the crossarm I86 imparts upward movement to the pin 206 against the tension of the spring 2I2. This continues until a stop screw 2I3 in the crossarm engages a fixed abutment 2I5 to arrest the advancement of the arm I18. In this position the arm I18 is yieldingly held against return movement by a pair of detents, one of which is illustrated in Fig. 3 and identified by the numeral 2I4. The detent 2I4 is fulcrumed at 2I6 in the machine head-and arranged to engage an extension of a crosspin 220 which connects the upper portion of the arm I18 to the toggle link I84, a light spring 2 I 8 serving to urge the detent downwardly into operating position. The detent is extended horizontally to take in the full range of movement of the crosspin220 with the arm I18 and is provided at opposite ends with recesses which terminate in beveled surfaces 222 which engage the crosspin 220 and yieldingly hold the arm I18 in its extreme positions. The inclination of the beveled surfaces 222 is such that the detents do not appreciably hinder the operation of the arm I18 by the treadle I16 but the downward pressure of the detents is sufficient to hold the arm stationary in its extreme positions. It will be understood that the construction and operation of that detent which is not shown in Fig. 3 is the same as the construction and operation of the illustrated detent 2I4. While the arm I18 is yieldingly held in its advanced position by said detents, the treadle is permitted to return to its elevated position illustrated in Fig. 1. At the beginning of the upward movement of the treadle, the hook I92 is lifted out of engagement with the pin I88 whereupon the spring 2 I2 swings the bellcrank lever 200 in a counterclockwise direction, as

seen in Fig. 13, thus transferring the interconnected hooks to the right into a position in which the flat surface 223 of the hook I94 engages the pin I90. As the treadle continues its upward movement, the surface 223 moves upwardly with relation to the pin I90 and just before the treadle comes to the limit of its upward movement, said surface passes by the pin I90 and thereupon the spring 2I2 swings the hooks farther to the right bringing the surface 225 of the hook I94 into contact with the pin I90 and positioning the hook I94 to engage said pin upon the next succeeding operation of the treadle and to swing the bellcrank lever together with the arm I18 in a clockwise direction, as seen in Fig. 13, to retract the wiper and its associated parts. It will be understood that during the latter part of such downward movement of the treadle, the lower pin 208 is moved downwardly against the tension of the spring 2I2 and during the next succeeding upward movement of the treadle, the spring 2 I 2 acting through the bell-crank lever 200 returns the interconnected links to their position illustrated in Fig. 13 in which the hook I92 registers with the pin I88. The momentum of the bell-crank lever tends to carr it somewhat beyond its normal rest position in which the pin I is located centrally with relation to the head 2l0, as shown in Fig. 13, but the detents, acting on the crosspin 220, prevent the momentum of the bell-crank lever from displacing the arm I18 from its extreme positions. The arm I18 is connected to the wiper carrier I30 by the toggle links I82 and I84 above-referred to and is connected to the presser bars I52 by parallel links 224 (Fig. 4) carried by the crosspin 220 and pivotally mounted in the rear end portions of said presser bars. During th advancement of the wiper, the toggle links are held in their straightened or horizontal position illustrated in Fig. 3 by a spring 226 which acts against a pin 228 extending rearwardly from the link I84, the straightened position of the toggle links being determined by engagement of a rearward extension 230 of the toggle link I82 with a stop screw 232 in the link I84. The advancement of the wiper is arrested by the engagement of an upward extension 234 of the link I62 with a stop screw 235 in .a bridge 231 connecting opposite side walls of the machine head but the advancement of the arm I18 continues as the toggle breaks to permit the presser bars I52 to be advanced relatively to the wiper as above described. It will be understood that during the return movement of the arm I18, the presser bars I52 move rearwardly relatively to the wiper as the toggle links return to their straightened position and thereafter the presser bars and the wiper are retracted in unison to their rest positions. Thus, the pressure of the presser bars I52 against the wiper is released before the wiper is retracted.

For expanding and bulging the toe portion of the overwiped upper, an inner form or mold 236 (Fig. 3) is mounted on a carrier 238 having an upwardly extending stem 240 slidably mounted in a bore in the block 38. The illustrated mold has the general shape of the toe portion of a last and is shaped symmetrically in order that it may operate alternatively on right and left uppers. The girth dimension of the illustrated mold, that is, the measure widthwise around the mold of its upper-engagingsurface, is substantially less than the inside girth dimension of uppers in the run of sizes to be operated. upon by said mold to the end that the upper may be loosely positioned on the inner upper-shaping plate 86 and the mold during the overwiping operation, thus permitting that operation to be performed with the upper entirely free from strain or tension. As shown in Fig. 12, the carrier 238 is generally T-shaped in cross section and the mold 236 has a complemental T-shaped recess extending longitudinally thereof and permitting a limited sliding movement of the mold on the carrier. The mold is normally held in its retracted position on the carrier as shown in Fig. 3 by a spring 242 mounted in a longitudinal groove in the central portion of the base of the carrier, one end of the spring being connected to a pin 244 projecting from the mold into said groove and the other end being connected to a pin 246 projecting from the base of the carrier into said groove. The mold is normally held updrawn against the bottom face of the plate 86 by a spring 248 surrounding the upper portion of the stem 248 and confined between a washer 259 on the stem and the upper surface of the block 38. For imparting downward movement to the mold 236 to expand the toe portion of the upper heightwise thereof, a bent hand lever 252 is mounted on a cross-shaft 254 journaled in ears 256 extendin upwardly from the machine head. The hand lever is connected by a link 258 to the rear portion of a lever 268, the forward portion of the link 258 being pivotally mounted on a pin 284 which is extended to provide a stop for the forward movement of the hand lever. The lever 260 carries at its forward end a screw 262 having a flat head 264 arranged to engage the upper end of the stem 248 when the block38 is in its downwardly swung position illustrated in Fig. 10. The lever 26!] has a downward extension 268 which is bored to receive the shaft 52 on which the lever is freely mounted. In order that the extent of downward movement of the mold 236 may be measured in accordance with the size of the upper to be operated upon, the screw 262 is provided with a headed cap 268 which may be turned to adjust the screw in the lever 268, and. the lower portion of the cap is provided with an edged flange 218 which registers with a suitable scale 212 (Fig. 2) which indicates the adjustment of the screw in terms of shoe sizes. The hand lever 252 also operates a bent presser lever 2.14 (Fig. 3) mounted on the cross-shaft 254 and arranged to apply downward pressure to the wiper carrier I38 to grip the wiper against the toe end of the welted margin of the upper. The lever 214 has pivotally mounted at its upper end a block 216 which. is bored to slide on a rod 218, the forward end of which. is pivotally mounted. in the rear portion of the lever 26!]. The block 218 is normally posi- 75.

tioned length-wise of the rod 218 between a spring 288 and a nut 282. Upon completion of the operation of the mold 236 and the presser lever 214 by the hand lever 252, the parts are arranged in their relative position illustrated in Fig. 11. It willbe seen that in this position of the parts, the lever 252 and the link 258 are so disposed that the compression of the spring 289 acts to maintain this position of the parts, since the pivotal connection or the hand lever .to thelink 258 has passed slightly beyond its dead center position and come to rest with the lower portion of the lever and the link bent downwardly slightly with the hand lever held against the pin 284 on which the link 258 is pivoted. In order that the outer forms 88 may be retracted to provide clearance for the longitudinal movement of the mold 236 in the upper-bulging operation, means is provided for retracting said outer forms as the presser bars I52 complete their-forward movement. To this end a bell-crank lever 2-86 (Figs. 1 and 10) is fulcrume-d at 288 in the machine head, the lower portion of said lever having a forward extension 298 from which a pin 292 projects laterally for engagement with the bracket I89 on the carrier plate 92. The bellc-rank lever 2851s swung in a counterclockwise direction, as seen in Fig. 10, during the latter part of the forward movement of the arm I18 when a roll 294 carried by said arm engages a cam surface 298 on the'under side of the horizontal portion'of the bell-crank lever.

The mold 236 is forced rearwardl'y to perform the upper-bulging operation simultaneously with the downward or upper-expanding movement. For imparting such rearward movement to the mold, a lever 296 (Fig. 3) is mounted on a crosspin 368 extending through lugs 382 on the block 38. Atthe lower end of the lever 298 a screw 384 is arranged to engage the flat forward surface of the mold 23-6. The lever 298 is normally held retracted by a torsion spring 386' (Fig. 2) surrounding the pin 398 and arranged to operate against a lateral extension 388 of the lever 298. The lever 298 is actuated by the hand lever 252 through a thrust bar 318- (Figs. 1 and 11) fulcrumed at 3| 2 on the lever 269. At its forward end, the'thrust bar 3 I 8 is provided with a shoulder 3M which engages a pin 3I6 in an upwardly extending arm 31-8 of the lever 298. When said lever is in its rest position illustrated in Fig. 1, it is positioned by the engagement of the upwardly extending arm 3I8 with a pin 328 on the thrust bar 3H]. While the extent of movement of the thrust bar is fixed, it will be understood that the extent of rearward movement of the mold 233* may be altered as desired by adjusting the screw 384 in the lever 298. Upon completion of the upper-expanding and bulging movement of the mold 236, the spring 289 (Fig. 3-) acting on thelink 258 and the hand lever 252 will yieldingly retain'the mold in its advanced position.

In order to cause the upper to retain the shape imparted to it by the illustrated machine, the operating parts are heated by an electrically operated unit 322. (Fig, 2) mounted in the machine head.

The heel-molding machine, illustrated in Fig. 2, is mounted in an extension of the machine head 28v and so positioned that the operator may readily transfer the upper from one machine to the other to complete the preshapingof theupper Preparatory to the sole-attaching operation. The illustrated heel-molding machine is similar in construction and operation to the toe-moldingent in the heel-molding machine.

machine above described except that the upperexpanding and bulging operations are not pres- Very briefly described, the heel-molding machine comprises an inner heel form or block 324 which forms the heel portion of the upper against a pair of complementally shaped outer heel molds 326. For wiping the welted margin over the top of the heel block 324 a heel wiper 3Z8'is mounted in a carrier 336. For applying downward pressure to the wiper to flatten out the welt, a pair of presser bars 332 are mounted for sliding movement lengthwise of the upper in guideways in the wiper carrier. 7 V

In the operation of the toe-molding machine an inverted prewelt upper is mounted on the toesupporting plate I68, the upper being held in a horizontal position by the operator who grips the opposite side portions of the welted margin with his two hands and holds those portions of the welt in a substantially horizontal position widthwise thereof in order to facilitate the operation of the wiper. After so positioning the upper, the operator depresses the treadle 46 to bring the upper-positioning plate 36 against the welted margin of the toe portion of the upper to locate said welted margin vertically and to cause it to register with the upper edge of the outer forms 83. The depression of the treadle 40 operates to bring the plate 86 into gripping engagement with the inner surface,of the upper after the plate 36 has positioned the welted margin as above described. The treadle 40 isthen permitted to return to its elevated position-retracting the upper-positioning. plate 36 but leaving the plate 86 in gripping engagement with .the upper as shown in Fig. 8 in which position it is locked by the pawl 64. The operator now depresses the treadle I16 simultaneously advancing the Wiper plate I26, the welt-conforming plate I38 and the presser bars I52. In the course of the advancement of these parts, the wiper first overwipes the corners of the toe portion of the upper, as shown in Fig. 6, bringing the toe portion of the welt into a horizontal plane and positioning the outer edge face of the welt to register with the welt-conforming plate which engages the welt immediately after it has been so positioned. The welt-conforming plate positions the welt uniformly widthwise thereof with relation .to the plate 86 so that a uniform width of the welted margin is wiped inwardly over the plate 66. The advancement of the welt-conforming plate is arrested by its engagement with the welt and the wiper continues its advancement while wiping pressure is imparted thereto by the operation of the springpressed pins I68 (Fig. 9) against the rails I21. Upon completion of the wiping movement of the wiper plate I26, the toggle links I82 and I84 swing downwardly permitting the presser bars- I52 to continue their advancement until their beveled ends engage the rolls I60 (Fig. 10) to apply gripping pressure to the wiper plate. The treadle I16 is then permitted to return to its elevated position whereupon the operator swings the hand lever 252 forwardly to perform the upper-expanding and bulgin operations. Preferably, the upper is permitted to remain in the machine with the operating parts in their advanced positions, as shown in Fig, 11, in order that the upper may set to the shape imparted thereto by the machine. While the upper is setting in the toe-molding machine, the operator molds the heel portion of another upper in the heel-molding machine above described and while said up- ISO per is setting in the heel-molding machine, the first-mentioned upper is removed from the toemolding machine and another upper is mounted therein. In retracting the operating parts of the toe-molding machine, the mold 236 is retracted forwardly and upwardly into its position illustrated in Fig. 10 by rearward movement of the hand lever 252 whereupon the treadle I16 is again depressed to retract the wiper plate and its associate parts. The pawl 64 is then withdrawn from the notch 68 in the plate 66 by the operation of a hand lever 334 (Fig. 8) secured to said pawl and the spring 62 (Fig. 1) swings the arm 60 downwardly returning the block 36 and the parts carried thereby to their rest position illustrated in Fig. 1.
