Kamborian, Boston, Mass. Filed Jan. 14, 1966, Ser. No. 520,603 20 Claims. (Cl. 118410) This invention relatesto improvements in the lasting of shoes and more particularly to an apparatus for depositing anadhesive on shoe parts that are to subsequently be bonded to each other. The illustrative embodiment is shown as being used with the heel seat lasting machine disclosed in pending U.S. application Ser. No. 478,185 filed Aug. 9, 1965 in which a shoe assembly including a last having an insole located at its bottom and a shoe upper draped thereabout is supported therein in a bottom-up position and in such a manner that a marginal portion of the shoe upper extends upwardly beyond the level of the insole to form an angulate portion between the upper margin and the insole. The particular embodiment of the instant invention has an adhesive applicator of a shape which is adapted to fit into the angulate portion of the shoe assembly whereupon adhesive may be forced from a source thereof through the applicator and onto the angulate portion of the shoe assembly in a pattern determined by the particular construction of the adhesive applicator.

The invention also includes a novel means of supporting the adhesive applicator which, briefly, includes support members mounted to the machine above the shoe assembly for movement which is towards and away from the shoe assembly. The adhesive applicator is suspended from the lower ends of the support members for limited universal movement with respect thereto so that as the support members are moved downwardly towards the shoe assembly to thus bring the adhesive applicator to bear against the shoe assembly, the adhesive applicator may adjust itself to the insole of'the shoe assembly to become seated in flush abutment therewith.

Another aspect of the invention resides in a guide mechanism which operatively engages the support members and causes them and the adhesive applicator supported therefrom to follow a predetermined path of movement when being moved towards the angulate portion of the shoe assembly.

Among the objects of the invention are:

To provide an adhesive applicator capable of applying adhesive to a shoe assembly without damaging or dislocating any of the shoe parts; and 'To provide an adhesive applicator capable of adapting itself in proper orientation with respect to a shoe assembly even if the shoe assembly itself is improperly supported.

Other objects and advantages of the invention will become apparent from the following specification and draw ings wherein FIGURE 1 is a side elevation of the machine;

Referring to FIGURE 1 the machine in which the instant invention is incorporated has a frame 10 to which is mounted a base 12. The base 12 and the various components mounted thereto are inclined at an angle of about 30 degrees to the horizontal to facilitate accessibility of the machine to the operator. Depending from the base 12 is a housing 14. For ease of explanation, the direction of the base 12 will be referred to as horizontal and the direction of the housing 14 will be referred to as vertical. In operating the machine, the operator stands to the right of the machine as it is shown in FIGURE 1 and motion towards the operator (left to right in FIGURE 1) will be described as forward while motion away from the operator (right to left in FIGURE 1) will be described as rearward.

As disclosed in the aforementioned pending application Ser. No. 478,185 filed Aug. 9, 1965, an air operated motor 16 is secured to the lower end of the housing 14 and has a piston rod 18 extending upwardly into the interior of the housing 14 (see FIGURE 2). The upper end of the piston rod 18 is connected to the lower end of a post 20, the post 20 being mounted in the housing 14 in such a manner as to permit both vertical axial and rotary motion about its longitudinal axis. The upper end of the post 20 protrudes beyond the upper end of the housing 14. The connection between the piston rod 18 and the post 20 is such that the post .20 may be rotated about its longitudinal axis without any interference between them. Brake means 22 (partially shown in FIG- URE 1 and more fully disclosed in application Ser. No. 353,462 filed Mar. 20, 1964) is operatively associated with the post 20 to prevent further rotational movement of the post once its desired angular position has been effected.

which is both independent of and unitary with the plat- 7 form 24. A drive mechanism 28 is mounted to the rear of the platform 24 and is operatively connected to the elongated base 26 to effect the movement of the base 26 with respect to the platform 24.

Referring to FIGURE 3 a shoe assembly which includes a last L, an insole I located at the bottom of the last and a shoe upper U draped about the last L, is supported on devices, described below, which in turn are carried by the platform 24. The shoe assembly is supported by these devices at its heel end and at its toe end while being oriented in a bottom-up and toe forward position. Referring to FIGURE 1 a pedestal 30 having a last pin 32 projecting upwardly therefrom is secured to the platform 24 and is effective to support the heel end of the shoe assembly in the manner fully disclosed in the aforementioned application Ser. No. 478,185. Mounted forwardly of the pedestal 30 and to the forward end of the moveable elongate base 26 is a toe supporting and shoe upper stretching mechanism 34 which is operative to initially grip the margin of the shoe upper at its toe end by means of pincers 36 and to subsequently pull the toe end of the upper horizontally forward and then vertically upward to tightly stretch the upper U about the heel end of the last L thereby insuring that the finished shoe will conform in shape to that of the last.

When the machine has performed this function the shoe assembly assumes the position shown in FIGURE 3, with the heel end of the upper tight about the last and the upper margin M extending upwardly above the level of the insole I. Secured to the top of the frame 10, above and rearwardly of the pedestal 30 and the upper stretching mechanism 34 is a head 38 about which are located mechanisms which hold the last L down firmly on the pedestal 30 to maintain the last in a rigid condition during sub sequent operations, clamp the heel of the upper to the last to thereby press the heel portion of the upper to the last thus insuring that the finished shoe will conform in shape to that of the last, extrude adhesive onto the heel end of the insole in a predetermined pattern and wipe the margin of the upper against that portion of the insole that has been coated with adhesive. Inasmuch as it is the adhesive extruding mechanism that is the subject of the instant invention, the other mechanisms will be described only to the extent necessary to properly illustrate its environrnent and use, reference again being made to the aforesaid application Ser. No. 478,185 for a complete disclosure of the structure and operation of these environmental devices.

Referring to FIGURE 4, guideways 40 are formed in the head 38 for slidable accommodation of a main slide plate 42. A head cover 44 is bolted to the head 38 and is spaced above the main slide late 42. The guideways 40 are of such construction as to restrict the main slide plate 42 to motion in a horizontal plane between a rearward, out-of-the-way position and a forward, working position. A fiuid operated motor 46 is operatively associated with the main slide plate 42 to effect the aforesaid motion thereof. The aforementioned mechanisms for Wiping the upper against the insole and clamping the upper against the heel end of the last are mounted to the main slide plate 42 for movement therewith, the primary function of the main slide plate 42 being to carry these mechanisms mounted thereto from a rearward, out-of-the-way position to a forward, working position.

To insure that the shoe assembly is rigidly supported during performance of the vertically upward stretching of the upper and subsequent operations, a holddown mechanism 48 is provided and is mounted to the head cover. The holddown mechanism has a holddown foot 50 which, when in a working position, is located above and in substantial alignment with the pedestal 30 upon which the heel portion of the shoe assembly is supported. With the shoe assembly mounted in the machine, the toe portion of the shoe upper U is gripped by the pincers 36 and is stretched horizontally in a forward direction. Immediately thereafter, the motor 16 is activated to raise the post 20 and shoe supporting mechanism carried thereon sothat the heel portion of the insole I is forced upwardly against the bottom of the holddown foot 50 thereby rigidly clamping the last L and insole I between the pedestal 30 and the holddown foot 50. Once so rigidly clamped, the subsequent operations of stretching the upper vertically, clamping the heel end of the upper U to the heel end of the last L, etc., may be performed with assurance that the shoe assembly will remain stationary.

The holddown mechanism 48 is so constructed that it may be horizontally withdrawn to a rearward, out-oftheway position so as not to interfere with the initial positioning of the shoe assembly in the machine. For purpose later described, the holddown foot 50 may be raised, thereby terminating its function of maintaining the shoe assembly in a rigid position. Referring to FIG- URES 4, 5, and 7 the holddown mechanism 48 includes a holddown slide 52 which is mounted for forward and rearward sliding motion in guideways 54 formed at the top of the head cover 44, the holddown slide 52 being retained in the guideways 54 by means of gibs 56. Formed integrally with the holddown slide 52 are a front clevis 58, a middle clevis 60, and a rear clevis 62. The rear clevis 62 is pinned to the piston rod 64 of an air motor 66. The air motor 66 is rigidly secured to a bracket 68 which in turn is mounted to and extends rearwardly of the head cover 44. Thus, activation of the motor 66 will cause the piston rod 64 to impart forward or rearward motion to the holddown slide 52 and all the components carried thereon. Swingably mounted to the front clevis 58 by means of a pin 70 for motion in a vertical plane is a holddown block 72 having a vertical bore 74 formed through its most forward end. A horizontal slot 76 is also formed in the holddown block 72 and intersects the vertical bore 74. A rod 78 having its upper portion threaded and the holddown foot 50 located at its lower end is slidably contained within the vertical bore 74, the threaded portion of the rod 78 being in engagement with a knurled nut 80 which occupies the horizontal slot 76. Thus the extent that the rod 78 and the holddown foot 50 protrude downwardly from the holddown block 72 may be varied by rotation of the nut 80. A ball 82 is spring biased upwardly against the underside of the nut 80 so as to act as a detent and radial grooves 84 are formed at the underside of the nut 80 to engage the ball 82, thereby maintaining the nut 80 and consequently the rod 78 in the position desired. The holddown mechanism is so constructed that when the motor 66 is activatedto move the holddown slide 52 to its forward, working position, the holddown foot 50 will be located above the pedestal 30.

An air actuated motor 86 is pivotally mounted to the rear clevis 62 and has a forwardly extending piston rod 88 to the forward end of which is mounted a clevis 90. The clevis 90 is part of a toggle linkage 92 which functions to cause the holddown block 72 to pivot rearwardly about the pin 70 thereby raising the holddown foot 50. The toggle linkage 92 has a pair of upper links 94 and a lower link 96, the upper links 94 being pivotally connected at one end to a rearwardly extending lug 98 which is an integral part of the holddown block 72 and pivotally connected at their other end to the clevis 90 by means of a pin 100. The lower link 96 is pivotally connected at one end to the middle clevis 60 on the holddown slide 52 and pivotally connected at its other end to the clevis 90 and the upper links 94 by means of a pin 100. It may thus be seen that operation of the motor 86 to cause the piston rod 88 to move rearwardly will impart a rearward (clockwise as seen in FIGURE 6) rotary motion to the holddown block 72 thereby raising the holddown foot 50. For the purpose of limiting and adjusting the extent that the holddown block 72 may rotate forwardly, a stop bolt 102 is threaded into the front of the lower link 96 whereby rotation of the lower link 96 in a counter-clockwise direction (as seen in FIG- URE 6) may terminate when the lower link 96 abuts the stop bolt 102. When the motor 66 is activated to move the holddown slide 52 to a forward, working position, the motor 86 is operative to maintain the piston rod 88 thereof in a forward position so that the holddown foot.50 is in its lower position when brought into vertical alignment with the pedestal 30.

When the shoe assembly is rigidly supported between the pedestal 30 and the holddown foot 50, the shoe upper U having been stretched tightly about the heel end of the last in both forward and upward direction, the air motor 46 is activated to cause the main slide plate 42, together with the mechanism carried thereon to be moved to a forward, working position. Referring to FIGURES 1, 4 and 6, a heel clamp'pad 104 (which is actuable by a drive mechanism not shown but fully disclosed in the aforementioned application Ser. No. 487,185, filed Aug. 9, 1965) is suspended from the main slide plate 42 and extends forwardly thereof. The heel clamp pad 104- is of a substantially U-shaped configuration and is adapted to embrace the heel end of the shoe assembly. It is suspended from the main slide plate 42 in such a manner that when the post 20 has been raised to cause the shoe assembly to be rigidly clamped between the pedestal 30 and the holddown foot 50, it will be at the same elevation as that of the shoe assembly so that when the main slide plate 42 is moved forwardly under the influence of the motor 46 the heel clamp pad 104 may move forwardly therewith until the bight 106 of the heel clamp pad 104 comes into abutment with the heel end of the shoe assembly (see FIGURE 16), the legs 108 of the heel clamp pad embracing the sides of the shoe assembly. Upon abutment of the bight 106 of the heel clamp pad 104 with the heel end of the shoe assembly the-drive mechanism for the heel clamp pad 104 is actuated to cause the legs 108 to swing inwardly towards the sides of the shoe assembly to thereby press the heel end of the shoe upper U tightly against the last L. (See FIGURE 17.)

Referring to FIGURES 4 and 6, a pair of wipers 110 are moveable mounted atop the main slide plate 42, which are operative, by means of a drive mechanism therefor, to fold and wipe the upwardly extending margin M of the shoe upper U against the heel end of the insole I. The wipers 110 are essentially fiat plates and are restricted to motion in a horizontal plane. The drive mechanism for the wipers 110 is operative to cause the wipers 110 to move over the heel end of the shoe assembly with a compound motion that is fully described in the aforementioned application Ser. No. 478,185.

In order for the wipers 110 to effectively wipe the upper margin M to the insole I, the shoe assembly must be at a height with respect to the bottom surface of the wipers 110 such that the bottom of the insole I is below the level of the bottom surface of the wipers 110 an amount equal to the thickness of the upper margin M. There is no provision in the machine for heightwise adjustment of the wipers 110.

Thus it may be seen that proper heightwise adjustment of the shoe assembly with respect to the wipers 110 must be effected by raising or lowering the elevation of the holddown foot 50 by means of the knurled nut 80 to thereby vary the height to which the shoe assembly may be raised in response to actuation of the motor 16.

An adhesive extruding device 111, which is the subject of the instant invention, is incorporated into the machine and functions to coat that portion of the insole to which the upper margin M will be subsequently wiped, with a bead B of adhesive such that when the upper margin M thereafter is wiped against the insole I the two may become permanently bonded to each other (see FIGURE 3). It should be noted, however, that the device could be modified to deposit the bead B of adhesive on the upper margin M or any other portionof the shoe assembly which is in the angledefined by. the insole I and the upper margin M without departing from the spirit of the invention.

The adhesive extruding device 111 is moveablylmounted to the holddown mechanism 48 so that it may have motion which is both unitary with and independent of the holddown mechanism in the manner described below.

Referring to FIGURES 4, 5, 6 and 7 it may be seen that a bracket 112 is secured to the top of the holddown block 72 by means of bolts 11 4. The rearward end of the bracket is formed into a clevis 116 having a pair of upwardly extending legs 118. Secured to and straddling the upper ends of the legs 118 is an air actuated motor 120 having a piston rod 122 extending downwardly therefrom between the legs 118 of the clevis 116. Another clevis 124 having downwardly extending legs is secured to the piston rod 122 of the motor 120. A lever 126 is pivoted, at a point intermediate its ends, to the clevis 116, for wardly of the legs 118, by means of a pin 128 and has a rearwar-dly extending end that is pivotally connected to the clevis 124 by means of a pin 130. It may thus be seen that activation of the motor 120 may serve to rotate the lever. 126 in a clockwise direction (as seen in FIGURES 6 and 7) to thereby raise the forwardly extending end thereof and in a counter-clockwise direction to thereby lower the forwardly extending end of the lever 126. A pair of parallel support members 132 are pivotally connected to the forwardly extending end of the lever 126 by means of a pin 134 in such a manner that they depend from the pin 134 and straddle the sides of the holddown block 72. A cement applicator 136 is suspended from the lowermost end of the support members 132 in a manner described below. Activation of the motor 120 thus causes a raising or lowering of the support members 132 and the cement applicator 136.

Referring to FIGURES 6, 7 and 8, a bracket 138, having a base 139 is provided which has, at the lateral extremities of the base 139, a pair of upwardly extending arms 140 and a pair of downwardly depending legs 142', the upwardly extending arms 140 being secured to the lower ends of the support members 132 by means of bolts 14 4. Inasmuch as the base 139 connects and spans the gap between the lower ends of the support members 132 and is located in the region occupied by the rod 78, a cut-out 141 is formed in the base 139 to accommodate the rod 78 so as to prevent mechanical interference between it and the cement applicator 136. The bracket 138 serves to support the cement applicator 136 and rigidity the support members 132 with respect to each other.

The cement applicator 136 is essentially an assembly composed of an upper support plate 146, an intermediate sealing plate 148, and a lower applicator plate 150. The lower applicator plate is adapted to simultaneously bear against the bottom of the shoe insole and the upwardly extending marginal portion of the upper and has a periphery of a contour which substantially corresponds to that of the heel end of the upper margin M when the shoe upper U has been stretched about the heel end of the last L so that the applicator plate 150 may be brought into complementary abutment therewith. The bottom surface 152 of the applicator is similarly adapted to bear against the insole bottom and has a lower, downwardly opening trough 154 formed therein which is of a shape substantially paralleling the peripheral contour of the heel end of the insole.

Referring to FIGURE 9, the upper surface 156 of the applicator plate 150 has an upper trough 158 formed therein which substantially parallels the lower trough 154. A plurality of conduits 160 are formed in the applicator plate 150 which serves to communicatively unite the upper and

lower troughs

158, 154. The intermediate sealing plate 148 is adapted to cover the upper surface 156 of the applicator plate 150 to thereby enclose the upper trough 158. A ferrule 162 having a passageway 164 formed therein is secured, as by soldering, to the sealing plate 148 and extends upwardly therefrom.

The passageway 164 of the ferrule 162 is in communication with the upper trough 158. The combined applicator plate 150, intermediate sealing plate 148 and ferrule 162 are removeable, as a separable unit, from the support plate 146 of the applicator assembly 136.

The upper support plate 146, which is receptive to the combined applicator plate 150, sealing plate 148 and ferrule 162 in a manner later described, is provided with a pair of laterally aligned holes 166 which accommodate pins 167 that protrude laterally therethrough into vertical slots 168 formed in the depending legs 142 of the bracket 138 so that the upper support plate 146 may be contained between and suspended from the depending legs 134'. The slots 168 are so formed as to permit a lost motion connection in a vertical direction between the bracket 138 and the upper support plate 146. The pins 167 are so oriented as to have their longitudinal axes laterally aligned in a horizontal plane, thus precluding rotary motion of the upper support plate 146 in -a horizontal plane yet permitting vertical motion and a forward-rearward rotary tilting motion about the axis of the pins 167. The depending legs 142 of the bracket 138 are spaced 2. distance corresponding to the lateral width of the cement applicator 136 so that a minimum of clearance between the legs 1'42 and cement applicator is provided, thus precluding lateral tilting of the cement applicator .136.

The support plate 146 is resiliently urged downwardly, for a purpose later described, so that when in an idle condition, the pins 167 are at the bottom of the slots 168. As may be seen from FIGURES 4, 7 and 8, secured to and extending upwardly from the support plate 146 are three columns 170'. The uppermost ends of the columns 170 protrude through holes 172 formed in the base 139 of the bracket 138 which are of greater size than the columns 170 so that the aforementioned tilting movements of the upper support plate 146 may not be retarded.

Washers 174 loosely encircle the upwardly protruding ends of the columns 170 and pins 175 are secured to the columns 170 to limit the downward travel of the columns 170 thereby precluding disengagement of the columns 170 with the bracket 138. A coil spring 176 circumscribes each of the columns 170 and is interposed between the upper surface of the support plate 146 and the lower surface of the base 139 of the bracket 138 thereby biasing the support plate 146 in its lowermost position.

The support plate 146 has at its forward end and integrally formed therewith, a fiitting 178 which is adapted to receive adhesive from a source thereof (not shown). Such a source of adhesive is, by way of example only, fully disclosed in US. application Ser. No. 472,525, filed July 16, 1965. The fitting 178 has a conduit 180 formed therein which opens into a vertical bore 182. The bore 182 is receptive to the ferrule 162 which is secured to the intermediate sealing plate 148 in such a manner that the passageway 164 of the ferrule 162 is in communication with the conduit 180 of the fitting 178. Effective sealing between the ferrule 162 and the fitting 178 by means of a suitable O-ring 184. The combined applicator plate 150, sealing plate 148, and ferrule 162 are detachably secured to the support plate 146 by means of a bolt 1'86 threaded upwardly through the applicator plate 150 and sealing plate 148 and into the support plate 146.

The result of such construction of the applicator assembly 136 is that cement applicators of different sizes may be easily interchanged when shoes of different sizes are to be fabricated in the machine.

It may be seen from the above that the entire cement applicator 136 is moveable towards and away from the shoe assembly in unison with the support members 132 and may additionally have limited universal movement, as above described, with respect to the support member 132 by means of the aforementioned spring-biased lost motion connection. A cut-out 188 is provided in the adhesive applicator 136 to permit the rod 78 to pass therethrough thereby preventing mechanical interference between the two.

' The cement extruding mechanism is provided with furthcr refinements, described below, which are operable to effect a guiding of the cement applicator 136 from the out-of-the-way position illustrated in FIGURE 11 to the working position illustrated in FIGURE 12 in response to actuation of the air motor 120. Referring to FIGURES 6 and 7, a pair of vertically spaced pins 190 are secured to the rod 78 and extend laterally from and on both sides of the rod 78, there being vertical slots 192 formed in each side of the holddown block 72 to permit such extension of the pins 190. The outer ends of the pins 190 extend beyond the lateral extremities of the holddown block 72. Secured to the outer ends of the pins 190 and on each side of the holddown block 72 is an identically shaped rearwardly extending arm 194. A pin 196 is secured to the rearward end of each of the arms 196 and traverses through the holddown block 72 by means of a vertical slot 198 formed therein for accommodation of the pin 196. The pin 196 is of such length that its extremities protrude laterally beyond the lateral extremities of the arms 194 and a roller 200 is rotatably mounted to each protruding extremity of the pin 196. Each roller 200 is so spaced on the pin 196 as to be located in substantially the same vertical plane as that of the support member 132 with which it is associated so that the support members 132 may be rotated about the pin 134 into abutment with the rollers 200. The dimensions of the

slots

192, 198 are such that adequate vertical heightwise adjustment of the rod 78, and its attendant holddown foot 50, is not impeded by abutment of the pins 190, 196 with their

attendant slots

192, 198. It may thus be seen that rotation of the nut to adjust the height of the rod 78 also serves to simultaneously, and to an equal degree, adjust the height of the arms 194 and the rollers 200 for a purpose later described.

As shown in FIGURES 5 and 6, a tension spring 202 is located on each side of the holddown block 72, each spring 202 being stretched between a pin 204 secured to each of the support members 132 and the pin so that the support members 132 may be continually urged rearwardly (counterclockwise as seen in FIGURE 6) about the pin 134 thus causing the rearward edge 206 of each of the support members 132 to bear against its associated roller 200 at all times. i

The rearward edge 206 of each of the support members 132 has .a portion thereof formed into a cam track 208 so that as the motor is activated to move the support members 132 downwardly, with the spring 202 continually urging the support members rearwardly against the rollers 200, the cooperation between the cam tracks 208 of the support members and the rollers 200 may cause the support members 132 to move in a rearward direction so that the resulting path of motion of the support members 132 and consequently the adhesive applicator 136 is compounded from the aforementioned downward and rearward motions. The contour of the cam tracks 208 may be varied to provide different resultant paths of motion should this be desired.

Referring now to FIGURES 11 and 12 it may be seen that the path of motion of the cement applicator 136 in the illustrative embodiment of the invention is between a forward and upward, out-of-the-way position (see FIG- URE 11) and a rearward and downward, working position (see FIGURE 12) wherein the cement applicator is in abutment with the shoe assembly. The tracks 208 are of such configuration that as the cement applicator 136 is moved from its out-of-the-way position to its working position it does not contact the insole I until it has actually reached its working position (as shown in FIGURE 12) thus eliminating the possibility of collision or scraping between the insole I and the cement applicator 136. Under ideal conditions the path of movement of the adhesive applicator 136 is as indicated by the broken arrows 210 in FIGURE 11. This path of movement is governed by the shape of the cam track 208 and its cooperation with its associated roller, 200. If, however, in orienting and stretching the upper U about the heel end of the last L, the upper U is inadvertently caused to have its upwardly extending marginal portion M inclined more forwardly than as illustrated in FIGURE 11 .or if the location of the last pin hole Htis such that the, shoe assembly and consequently the upper margin M is located more forwardly than as illustrated in, FIGURE 11 then the adhesive applicator 136 may initially abut the upper marginM prior to its reaching its working position. Should this happen, the resistance to rearward urging of the support member 132 and adhesive applicator 136 by means of the springs 202 will be transferred from the rollers 200 to the inner surface of the upper margin M upon which the adhesive applicator 136 bears. It may thus be seen that the path of motion of the cement applicator 136 will be governed by the inclination of that portion of the upper margin M which is in abutment with the adhesive applicator 136. Such operation of the apparatus is illustrated in FIGURE 13 wherein the path of motion is designated by the broken arrows 212, the node 214 in the arrows 212 indicating the change of path of motion that occurs when the adhesive applicator abuts the upper margin M.

It may sometimes occur, in the use of the machine, that the upper is formed from relatively thin and weak material so that the upper margin M would not have the strength to resist the rearward motion of the adhesive applicator and thereafter cause it to berguided into its working position. It may also occur that the upper margin M curls or is inclined rearwardly as illustrated in FIGURES 14 and 15 with the result that it similarly could not properly resist the rearward motion of the adhesive applicator 136. It such shoe materials are being used and if the normal configuration of the cam tracks 208 of the support member 132 is such that the adhesive applicator 136 would be brought too far rearwardly with respect to the particular shoe assembly being worked on if the cam track 208 alone were used to guide the adhesive applicator 136, then an additional device is provided in the apparatus which is effective to terminate rearward movement of the adhesive applicator 136 independently of the position of the upper margin M or the configuration of the cam tracks 208. This device is simply a stop bolt 214 which is threaded into the holddown foot 50 and extends forwardly therefrom so that by rotation of the bolt 214, the degree to which the bolt may extend forwardly may be varied. Referring to FIGURE 14 it may be seen that the bolt 214 protrudes from the holddown foot 50 to a greater extent than in FIGURES 11, 12 and 13. Upon operation of the motor 120 the adhesive applicator 136 will begin its motion in a rearward and downward direction, its path being governed by cooperation of the cams 208 and the rollers 200 until the forward portion 216 of the inner periphery of the adhesive applicator comes into abutment with the forwardly extending end of the bolt 214 whereupon resistance/to rearward urging of the support members 132 and adhesive applicator 136 by means of the springs 202 will be transferred from the rollers 200 to the bolt 214 against which the inner periphery of the adhesive applicator then bears. Thus it may be seen that upon abutment of the adhesive applicator 136 with the bolt 214 rearward motion of the adhesive applicator will terminate, the motor 120 being effective to move theadhesive applicator in a downward direction only, with the forward portion 216 of the inner periphery of the applicator 136 sliding against the forwardly extending end of the bolt 214. Such operation of the apparatus is illustrated in FIGURES 14 and 15 wherein the path of motion is designated by the broken arrows 218, the node 220 in the arrows 218 indicating the change of path of motion that occurs when the adhesive applicator 136 abuts the bolt 214.

"When the shoe assembly has been presented to the machine and been manipulated therein it may occasionally happen that the shoe assembly, including the insole,

is tilted rearwardly or forwardly so that as the adhesive applicator is brought to bear against the insole by the aforementioned mechanism, the bottom surface 152 thereof may not be in flush and complete abutment with the insole bottom. The aforementioned mounting of the adhesive applicator 136 for limited universal movement is effective in such a case, to permit the adhesive applicator to seat itself in flush abutment on the bottom of the insole in response to continued downward urging of the support members 132 by the motor 120. When the adhesive applicator has seated itself properly the springs 176 are effective to maintain the adhesive applicator 136 in this position.

i The control circuit of the machine is such that when the adhesive applicator 136 is in flush abutment with the insole I, adhesive is forced from. a source thereof (not shown) into the fitting 178 of the adhesive applicator 136. The adhesive then flows through theconduit 180, the passageway 164 and into the upper trough 158 formed in the applicator plate 150. From the upper trough 158 the adhesive flows through the conduit 160 to the lower trough 154 which, by means of abutting co-' operation between tthe bottom surface 152 of the adhesive applicator 136 and the insole bottom, has become enclosed therebetween so that when adhesive is introduced into the lower trough 154 it may fill the lower trough 154 and simultaneously adhere to the insole in a pattern determined by the configuration of the lower trough 154.

The adhesive applicator 136, having thus performed its function, is then withdrawn to its non-working position, leaving the deposited pattern of adhesive on the insole bottom (see FIGURE 3).

As described earlier, the holddown is provided with a mechanism to permit heightwise adjustment of the holddown foot 50 so that the shoe assembly and particularly the insole may be raised to a proper level with respect to the wipers 110 upon actuation of the motor 16. Inasmuch as there is no corresponding heightwise adjustment for the adhesive applicator 136, the raising of the insole level results in decreasing the distance between the cement applicator 136 and insole I which tends to cause the adhesive applicator 136, upon activation of the motor 120, to abut the insole before it has reached its desired rearward position. Similarly, the lowering of the insole level by lowering the holddown foot 50 results in increasing the distance between the adhesive applicator 136 and insole I which tends to permit the adhesive applicator 136 to move rearwardly an amount greater than desired before it abuts the insole, with the result that, in both cases the adhesive applicator 136 would be improperly positioned on the shoe assembly. In order to insure that the rearward movement of the adhesive applicator 136 begins at the proper time, the structure of the device is such that the cam tracks 208 of the support members 132 engage the rollers 200, thus initiating the rearward component of movement of the adhesive applicator 136, when the adhesive applicator 136 is spaced a predetermined distance from the insole I, irrespective of the height of the holddown foot 50 and the insole I. This result is effected by mounting the rollers 200 as earlier described, i.e. the rollers 200 are mounted to the arms 194 which are in turn secured to the rod 78 by means of the pins so that as the height of the rod 78 and holddown foot 50 is adjusted, the height of the rollers 200 will be adjusted a corresponding amount in unison therewith. It may thus be seen that, irrespective of the level to which the insole is raised, the rollers 200 will always remain spacedfrom the insole by a constant predetermined distance. Thus, when the holddown foot 50 is adjusted to a greater elevation, the rollers 200 will be carried upwardly towards the cam tracks 208 of the non-adjustable support arms 132 so that even though the adhesive applicator 136 will be closer to the insole I and would tend to bear against it at an earlier time, the rollers 200 will be similarly closer to the cam tracks 208 of the support members 132 so that the cam tracks 208 may engage the rollers 200 at a corresponding earlier time. Similarly when the holddown foot 50 is adjusted to a lower elevation, the rollers 200 will be carried downwardly from the cam tracks 208 so that even though the adhesive applicator 136 will be more distant from the insole I and would thus tend to bear against it at a later time, the rollers 200 will be similarly more distant to the cam tracks 208 so that the cam tracks 208 may engage the rollers 200 at a correspondingly later time.

After the bead B of adhesive has been deposited on the insole I as aforementioned, the control-circuit of the machine causes the motor 120 to be actuated to retract the adhesive applicator 136 to its non-working, out-of-theway position and thereafter actuate the wiping mechanism to cause the upper margin M to be folded over and pressed against the insole I. The configuration of the lower trough 154 is U-shaped (see FIGURE and substantially parallels the periphery of the heel end of the insole so that the bead B of adhesive deposited thereby will lie in the region of the insole onto which the upper margin M is subsequently folded and pressed by the wipers 110 so that the upper margin M may become bonded to the insole I.

The remainder of the cycle of operation of the machine is identical to that of the machine disclosed in the aforementioned application Ser. No. 478,185, filed Aug. 9, 1965. During the operation of the wiping mechanism, the control circuit causes the pincers 36 to release their grip on the shoe upper U. Towards the end of the wiping stroke when the wipers 110 have folded the upper margin M against the insole I, the upper margin M then being pressed between the bottom surface of the wipers 110 and the insole I, the control circuit of the machine causes the motor 86 to be activated to effect a rearward pivoting of the holddown block 72 thereby raising the holddown foot 50 from the shoe assembly so that the entire resistance to upward movement of the shoe assembly, in response to the continuous upward force of the motor 16, is resisted by the bottom surface of the wipers 110. The upwardly directed force of the motor 16 is then increased, in response to a signal from the control circuit, to cause the upper margin M to be more firmly pressed between the insole I and the bottom surface of the wipers 110 to insure that the bond between the upper margin M and the insole I will be permanent. The duration of time for which this increased upward force, or bedding pressure is applied is dependent on the bonding characteristics of the adhesive and the materials used in the shoe assembly. It should be noted that when the motor 86 is actuated to cause the holddown foot 50 to be raised, the entire adhesive applicator mechanism, which is mounted on the holddown block 72, will pivot rearwardly in unison therewith. This, however, is of no consequence because the adhesive applicator mechanism has already performed its function and has been previously retracted to a non-working, out-of-the-way position.

When the aforementioned bedding pressure has been maintained for a sufiicient time, the various components of the machine are caused, by means of the control circuit, to be returned to their idle, non-working positions and the heel seat lasted shoe assembly may be removed from the machine.

Summarizing the operation of the machine, the shoe assembly is initially presented to the machine with the heel portion thereof supported on the pedestal 30 and the toe portion thereof supported in the toe supporting and shoe upper stretching mechanism 34 with the toe portion of the upper U inserted between the open jaws of the pincers 36. The pincers 36 are then activated to grip the upper U. The shoe upper stretching mechanism 34 is then activated to move the pincers 36 horizontally in a forward direction to thereby stretch the upper U about the last L, the last L being maintained in its original position by means of engagement of the last pin'32 and the last pin hole H of the last L. The control circuit is so constructed as to permit the operator to interrupt the operation of the machine and inspect the shoe assembly after the pincers 36 have gripped the upper U and also to inspect it after the upper stretching mechanism 34 has effected the horizontal stretching of the upperU so that if either of these operations has not been satisfactorily performed the machine may be returned to its original idle position and the cycle started over again. When the operator is satisfied with the gripping and horizontal stretching of the upper he may then resume operation of the machineIIn resuming operation, the control circuit causes the motor 66 to be actuated to move the holddown slide 52 and holddown mechanism 48 mounted thereon to a forward working position such that the holddown foot 50 is positioned directly above the pedestal 30 and the heel of the insole I. After the holddown mechanism 48 has been moved to its forward, working position, the control circuit causes the motor 16 to be actuated to thereby raise the toe post 20 and the shoe assembly supported thereby until the heel portion of the insole bottom is brought into abutment with the bottom of the holddown foot 50, the elevation of the holddown foot 50 having been previously adjusted so that the insole I may be brought to the proper elevation with respect to the wipers 110. As the toe post 20 rises, the control circuit causes activation of the motor 46 to move the main slide plate 42 and thus the heel clamping and wiping mechanisms which are supported thereby to a forward, working position, the control circuit being operative to insure that the toe post 20 has been raised to bring the insole I into abutment with the holddown foot 50 before the bight of the heel clamp pad abuts the heel end of the shoe assembly. When the bight of the heel clamp pad 104 does abut the heel end of the shoe assembly the control circuit causes activation of the heel clamp mechanism to swing the legs 108 of the heel clamp pad 104 inwardly towards the shoe assembly, thereby pressing the upper U more firmly to the heel portion of the last L.

After the shoe assembly has been brought into abutment with the holddown foot 50 but before the heel clamp mechanism is actuated to swing the legs 108 of the heel clamp pad 104 inwardly towards the shoe assembly, the control circuit causes the upper stretching mechanism 34 to effect a vertical raising of the pincers 36 to thereby stretch the upper U vertically about the last L.

Thus, at this point of time in the cycle of operation of the machine the shoe assembly is rigidly supported with'the upper U being in a stretched condition about the last L and being firmly pressed to the heel end of the last L by the heel clamp pad 104. When theshoe assembly is in this condition it is in readiness to receive the bead B of adhesive. The control circuit is effective, after the heel clamp 104 has pressed the upper to the last L, to actuate the motor thereby imparting substantially downward movement to the support members 132 and the adhesive applicator 136 mounted thereto. The support members 132 continue their substantially down ward movement under'the influence of the motor 120 until the cam tracks 208 of the support members 132 engage their associated rollers 200 Whereupon the move; ment of the adhesive applicator 136 is compounded by the addition of a substantially rearward component of motion due to the shapeof the cam tracks 208. As described earlier, the rearward component of motion of the adhesive applicator 136 may be, in some instances, governed by the abutment of the adhesive applicator with the upper margin M or the stop bolt 214 depending on the configuration of the shoe assembly. However, in all cases, there is no translatory movement of the adhesive applicator 136 in a forward or rearward direction once the adhesive applicator 136 comes into abutment with the insole bottom. The adhesive applicator 1'36 is'thus' in a working posi-tion'and inrreadiness to distribute adhesive to the shoe assembly as soon as it abuts the insole.

*xWhQIL the adhesiveapplicator 136has become seated in fiush' abutment with the bottom of, the insole I, the control circuit causes adhesive to be forced from a source thereof intothe fitting 178 wherefrom it is forced through the conduit 180, the-passageway 164, the upper trough 158,.1the conduits 160 and into the lower trough 154 whereupon ltheadhesive may fill the lower trough 154 and adhere to the insole I in a pattern determined by the configuration of the lower trough 154. As mentioned earlier, the source of adhesive anay be any suitable one, an example of such a source being disclosed in application Ser. No. 472,525, filed July 16, 1965.

After the bead B of adhesive has been deposited on the insole I the control circuit causes'activation of the motor 120 to raise'the support members 132 and the adhesive applicator'136"to its idle position; The control circuit then causes the wiping mechanism'to be actuated so that the wipers 110 move towards the shoe assembly and engage the upper margin M to fold the upper margin M against the insole I with the bead of adhesive being sandirviched therebetween. During the latter'part of the stroke of the wipers 110 the control circuit causes the pincer-s 36 to release their grip on the upper U for reasons more fully disclofsed in United State application'Ser.No. 294,351, filed'July 11, 1963.

At or near ,the end of the wiper stroke the control circuit causesthe motor 86 to become activated thereby effecting a raising of the holddown foot 50 from the insole bottom, thus transferring the upwardly directed force of the motor 16 from the holddown to the bottom surface of the Wipers 110. At approximately the'same time-as the holddown foot 50 is raised, air is introduced under increased pressure, into the motor 16 to cause the upper margin M to be pressed between the insole I and the bottom surface of the wipers 110 to effect a more permanent bond between the insole I and upper margin M When this increased bedding pressure has been apphed fora sufficient length of time the control circuitcauses all the mechanisms that have not yet been returned to an idle position to be so returnedand the heel seat lasted shoe assembly may be removed from the machine.
