METHOD AND MECHANISM FOR APPLYING CEMENT IN THE CORNER BETWEEN AN UPPER MARGIN AND AN INSOLE BACKGROUND OF THE INVENTION U.S. Pat. No. 3,675,260 is illustrative of prior art dealing with applying cement into the corners between a portion of an upper margin mounted on a last and the corresponding portion of the periphery of an insole lo cated on the last bottom prior to wiping the upper margin portion against the insole portion. The cement is applied by nozzles that travel along the corners while yieldable heightwise forces are applied by the nozzles against the insole and yieldable outward forces are applied to the nozzles to cause the nozzles to stay in the corners during their travel.

This invention is concerned with an improvement over the cement applying mechanism of the type of U.S. Pat. No. 3,675,260 that is to be used with a shoe assembly wherein at least one end portion of the upper margin has been wiped against the insole and at least one nozzle travels along an unwiped portion of the upper margin that bounds the previously wiped end portion and applies cement into the corner between the unwiped upper margin portion and the corresponding portion of the insole periphery.

SUMMARY OF THE INVENTION In a first aspect of the invention, at least one end portion of the upper margin has been wiped against the insole. The shoe assembly is supported bottomup and a nozzle, located above the shoe assembly, is caused by yieldable downward and outward forces to move into the comer between an unwiped portion of the upper margin and the corresponding portion of the insole periphery in a location that is rearward of the boundary between the unwiped margin portion and the previously wiped end portion of the upper margin. The nozzle is then caused to move towards this boundary, while the downward and outward forces are maintained, until it arrives at the boundary. The nozzle is then caused to move rearwardly away from the boundary, while the downward and outward forces are maintained, and while cement is extruded from the nozzle into the corner until the nozzle arrives at a desired location. The nozzle is then moved inwardly of the comer and raised away from the insole. This arrangement ensures that cement is extruded along the entire length of the unwiped portion of the upper margin between the boundary and the desired location regardless of the length and configuration of the unwiped portion;

In a second aspect of the invention at least one of the end portions of the upper margin has been wiped against the insole and the corners between the upwiped portions of the upper margin that extend rearwardly of the wiped end portion on the opposite sides of the shoe assembly and the corresponding portions of the insole periphery are to have cement extruded therein. This is accomplished by providing a pair of the nozzles, each of which travels along the corners in the unwiped portions of the upper margin towards the boundaries between the unwiped portions and the wiped end portion until the nozzles arrive at the boundaries between these portions after which the nozzles are caused to travel away from these boundaries while cement is extruded from the nozzles. The nozzles are mounted to travel in unison and are also provided with a compensating arrangement that permits relative movement of the nozzles with respect to each other lengthwise of the shoe assembly. The compensating arrangement insures that both nozzles are at the boundaries when the nozzlc travel towards the boundaries is completed.

DESCRIPTION OF THE PREFERRED EMBODIMENT In the description set forth below, the left end of the mechanism as seen in FIGS. I and 2 will be considered to be the front of the mechanism and the right end of the mechanism in these figures will be considered to be the back of the mechanism. Directions extending towards the front of the mechanism (right to left in FIGS. 1 and 2) will be considered to be "forward" and directions extending towards the back of the mechanism (left to right in FIGS. 1 and 2) will be considered to be rearward."

Referring to FIGS. 1 and 2, the cement applying mechanism includes a stationary base 10 having a pair of front posts 12 and a pair of back posts 14 upstanding therefrom. The

posts

12 and 14 are located on opposite sides of the base 10 and a pair of slide rods 16 are secured to and extend between each set of

posts

12 and 14 so as to be located on opposite sides of the base 10 and so as to extend in forward-rearward directions. A bearing 18 is slidably mounted on each slide rod 16 for forward-rearward movement and a slide plate 20 extends between the bearings 18 and is secured to bearing blocks 19 that are mounted to each of the bearings 18.

An air operated motor 22 is pivoted to a post 24 that extends upwardly of the back of the base 10. The motor 22 extends forwardly of the post 24 and has a forwardly extending piston rod 26 that is pivoted by a pin 28 (FIG. 3) to a link 30 between the ends of this link. One end of the link 30 is pivoted by a pin 32 to the front of a link 34, the back of the link 34 being pivoted to a post 36 that extends upwardly of the base 10 forwardly of the post 24. The link 30 extends rearwardly of the pin 32 and laterally towards a side of the base 10, and the end of the link remote from the pin 32 is pivoted to a post 38 that extends upwardly of the link 30 and is secured to a bearing block 19.

Referring to FIGS. 3 and 5, a projection 42 extends inwardly of the bottom of a post 44 that depends from a bearing block 19. A valve 46, mounted to the projection 42, has a forwardly directed valve stem 48 that is spring urged forwardly by the conventional spring in the valve 46 so as to urge the valve stem 48 against a valve actuating rod 50 that is pivoted to the projection 42 for forward-rearward swinging movement about the axis of a pin 52. The valve stem 48 urges the rod 50 forwardly about the axis of the pin 52 to a position wherein the front of the rod 50 engages a stop pin 54 that is upstanding from the projection 42.

Referring to FIGS. and 6, a guide 56, secured to the base by bolts 58, slidably supports a rail 60 for forward-rearward movement. The rail 60 has a plurality of notches 62 in its upper surface that are selectively engagable by a prong 64 thatdepends from a lever 66. The lever 66 is pivoted to a pair of clevises 68 that are mounted to extend laterally of the guide 56 by a pin 69 and is spring urged into engagement with a selected notch 62 by a compression spring 70 that is interposed 104 to which is attached a downwardly depending plunger 106 that is slidable in the bore 102. An orifice 108 in the bottom of the sleeve 100 has a valve seat 110 formed thereon that is cooperative with a ball valve 112 to close the orifice 108 in response to upward movement of the plunger 106 in the manner described below. The ball valve normally rests on a support member 114 that is mounted to the cement pot 90 so that communication is provided between the orifice 108 and a passage 116 located below the orifice 108.

Referring to FIGS. 7 and 8, a prong l 18 is secured to and extends downwardly and forwardly of the cement pot 90. A block 120 is pivoted to a post 122 extending upwardly of the front of the prong 118 for swinging movement about the upright axis of the post 122. A projection 124 (FIG. 2) extends laterally of each side of the block 120 and a stabilizer bolt 126 is secured to each projection 124 with a head 128 of each bolt 126 extending rearwardly of its associated projection 124. As shown particularly in FIGS. 2 and 4, a pair of single acting spring return air operated motors 130 are so mounted to the slide plate 20 that their forwardly directed piston rods 132 are in alignment with the bolt heads 128.

A pair of aligned spindles 134 (FIG. 8) are mounted for swinging movement about a horizontal axis in projections 136 of the block 120, the spindles having extensions 138 that extend outwardly of the block 120. A

heightwise extending spindle 140 (see FIGS. 8 and 9) O between the guide 56 and a downwardly depending leg 72 of the lever 66. A bolt 73 is threaded into the rail so as to effect forward-rearward adjustment of the rail 60 and the parts carried by the rail 60 by pushing and pulling on the bolt 73.

A column 74 extends upwardly of the front of the rail 60 and a support 76 extends rearwardly of this column. An air actuated motor 78 is pivoted to a clevis mounted to the support 76 and the piston rod 82 of the motor 78 extends rearwardly of this motor. The top of a bar 84 is pivoted to a clevis 86 that is secured to the back of the piston rod 82. The bottom of the bar 84 is so pivoted to the back of the support 76 that a stop lug 88 extends below the support 76 in alignment with the outer end of the rod 50 that is remote from the pin 52.

Referring to FIG. 1 and 7, a cement pot is mounted to the slide plate 20 for forward-rearward movement therewith. The cement pot includes a funnel 92 into which solid granules of thermoplastic cement is supplied and a storage chamber 94 into which the solid cement gravitates from the funnel 92 and in which the cement is melted by heating means (not shown). The molten cement gravitates from the chamber 94 through a passage 96 and an orifice 98 in a hollow sleeve into a bore 102 forming the hollow interior of the sleeve 100. The sleeve 100 is mounted to the cement pot 90. An air operated motor 102, also mounted to the cement pot 90, has a downwardly depending piston rod is rotatably mounted in each spindle extension 138 and a nozzle carrier 142 is mounted to an extension 144 of the spindle so as to extend forwardly thereof. A nozzle holder 146 is mounted to the front of each nozzle carrier 142 and a nozzle 148 is mounted to and depends downwardly of each nozzle holder 146. Interconnected passage means 152 in the cement pot 90, the prong 118, the block 120, the post 122, the spindles 134, the spindle extensions 138, the spindles 140, the nozzle carriers 142, the nozzle holders 146 and the nozzles 148 provide communication for the molten cement between the passage 116 and passages 154 (FIG. 10) located in each of the nozzles 148. Strategically located electric cartridge heaters such as the heaters 161 shown in FIGS. 9 and 10 serve to maintain the cement that is in the passage means 152 and the passages 1S4 molten. A check valve 163 (FIG. 10) in each nozzle holder 146 yieldably blocks the How of cement through the passage means 152.

Each spindle extension 144 has a bar 162 (FIGS. 7-9) extending rearwardly thereof -that has a bar 164 depending from its back end. Each bar 164 is mounted to a yoke 166. One of the yokes 166 is secured to the cylinder 168 (FIG. 11) of an air operated motor 170 and the other yoke 166 is secured to the piston rod 172 of this motor. As described below, the operation of the motor 170 serves to swing the nozzle carriers 142 and the bars 162 about the axes of the spindles 140. The extent of outward movement of the bars 162 and the extent of inward movement of the nozzle carriers 142 is determined by the engagement of the bars 162 with stop bolts 174 that are located outwardly of the bars 162 and are mounted to bars 176 that in turn are secured to their associated block extensions 138.

A rod 178 (FIGS. 4) attached to and extending rearwardly of each projection 124 of the block 120 has a post 180 depending from its back, and an air operated motor 182 is pivoted to the bottom of each post 180.

A lug 184, depending downwardly of and connected to each spindle extension 138, is pivoted to a clevis 186 that is secured to the piston rod 188 of its associated motor 182, the piston rods 188 projecting forwardly of the motors 182.

Referring to FIGS. 5 and 12, a rod 190 rotatably mounted in a housing 192 that is secured to the top of one of the front posts 12. A knob 194, secured to the front of the rod 190, has a pluarlity of recesses 196 therein that are registerable with a spring pressed detent 198 in the housing 192 so that the rod 190 may be rotated by the knob 194 and held in a desired position by the pressing of the detent 198 in a desired recess 196. A sleeve 200 and a core 202 are connected to each other by a pin 204 and are slidably mounted on the rod 190 for forward-rearward movement. A bolt 206 is threaded into the core 202 and is rotatable by a handle 208 so as to adjust the forward-rearward position of the sleeve 200. A plurality of stop knobs 210 are mounted to the sleeve 200 so as to project radially therefrom in a spiral pattern.

Referring to FIGS. 2 and 5, a valve 212 is mounted to the slide plate and has a forwardly projecting valve stem 215 that is resiliently urged forwardly by the conventional spring in the valve 212 so as to urge the valve stem 214 against a valve actuating bar 216 that is pivoted to the valve 212 on a pin 218. The outer end of the bar 216 is in alignment with a selected one of the knobs 210.

Referring to FIGS. 1, 2, 3 and 13, a rod 220 extends between and is rotatably mounted in a front post 12 and a back post 14. A knob 222 is mounted to the rod 220 forwardly of its associated front post 12 rearwardly of its associated back post 14. The rod 220.;is connected by

sprockets

224 and 226 and a chain 228 to a threaded shaft 230 that is rotatably mounted in the back post 14 associated with the rod 220 below the rod 220 and extends forwardly of this post 14. The front of the shaft 230 is rotatably mounted in a pillar 232 that is secured to and extends upwardly of the base 10. A rod 234 extends between and is secured to the pillar 232 and the back post 14 associated with the shaft 230 and is located below the shaft 230. A block 236 is threaded onto shaft 230 and has a pair of depending lugs 238 that straddle the rod 234 whereby the forward-rearward position of the block 236 may be ad justed by rotating the knob 222 to rotate the threaded shaft 230. An air operated cylinder 240 is mounted for heightwise movement in a cavity 242 in the block 236 and is resiliently urged downwardly of the block by tension springs 244 that extend between pins 246 anchored to the cylinder 240 and pins 248 anchored to the block 236. The bottom of the cavity 242 is in communication with a coupling 250 that is connected, via lines described below, to a source of pressurized air. A valve 252 is mounted to a flange 254 that is secured to the top of the cylinder 240, the valve 252 being offset outwardly of the cylinder 240. The flange 254 includes a forwardly facing upper portion 256 having a forwardly facing stop surface 257 (FIG. 2) that is approximately at the level of the top of the cylinder 240 and a lower surface portion 258 to which the valve 252 is mounted and through which the upwardly projecting valve stem 260 of the valve 252 extends, the valve stem 260 being urged upwardly by the conventional spring in the valve 252 so as'to bear against a valve actuating rod 262 that is pivoted for heightwise movement by means of a pin 264 that is mounted to a bracket 266 that in turn is secured to the flange portion 258. A cam 268 is mounted to the bearing block 19 associated with the back post 14 in which the shaft 230 and the rod 234 are mounted. The cam 268, as described below, is in alignment with the stop surface 257 and the valve actuating rod 262 when the cylinder 240 has been raised to an upper position.

In the idle condition of the machine: the piston rod 26 is retracted into the motor 22 to thereby locate the slide plate 20 and the parts carried thereby, including the cement nozzles 148, in a rearward position with the cam 268 located rearwardly of the valve 252 and the flange 254; the piston rod 82 is retracted into the motor 78 so that the stop lug 88 is in alignment with the rod 50; the piston rod 104 is retracted into the motor 102 so that the bottom of the plunger 106 is above the orifice 98; the piston rods 132 are projecting out of the motors and bear against the bolt heads 128 so that the block 120 is locked against movement about the upright axis of the post 122; the cylinder 168 and the piston rod 172 of the motor 170 are extended away from each other so that the nozzles 148 are swung about the axes of the spindles to positions that are relatively close to each other in positions determined by the engagement of the bars 162 with the stop bolts 174; the piston rods 188 are projected out of the motors 182 to thereby swing the nozzles 148 about the axis of the spindles 134 to raised positions; and the cylinder 240 is retained in a lowered position in the block 236 by the springs 244 to thereby lower the stop surface 257 and the valve actuating rod 262 out of intersecting relation with respect to the cam 268.

Thermoplastic cement is placed in the funnel 92 of the cement pot 90, gravitates into the chamber 94 wherein it is melted, and the molten cement flows from the chamber 94 through the passage 96, the orifice 98, the passage 116, and the passage means 152 up to the valves 163 in the nozzle holders 146.

The cement applying mechanism of this invention is intended to be used with a shoe lasting machine 270 (FIG. 2A) of the type disclosed in pending U.S. Pat. application Ser. No. 227,376 filed Feb. 18, 1972. The lasting machine 270, which is located forwardly of the cement applying mechanism, includes a shoe support 272 that incorporates a toe rest 274 and a last pin 276. A plurality of lasting instrumentalities 277 are located on each side of the shoe support 272.

A shoe assembly 278, (FIGS. 15 and 15A) comprising a last 280 having an insole 282 located on its bottom and an upper 284 mounted thereon, is placed bottom-down on the shoe support 272 with the vamp of the shoe assembly resting on the two rest 274 and with the last pin 276 inserted into the thimble in the back portion of the last so that the toe of the shoe assembly fares forwardly. Prior to placement in the lasting machine, the shoe assembly 278 had been toe lasted and heel seat lasted.

Referring to FIG. 16, each lasting instrumentality 277 is formed of three plies, the outer ply being an outer presser strap 286, the middle ply being an inner presser strap 228, and the inner ply being a lasting strap 290. In the manner described in the aforementioned U.S. Pat. application Ser. No. 227,376, the lasting instrumentalities are brought to the FIG. 16 position wherein they engage the side portions of the shoe assembly between the previously lasted toe and heel portions. in this position, the margins 292 of the unlasted side portions of the upper margin extend upwardly of the insole 282, the lasting instrumentality plies 286, 288 and 290 are pressing the side portions of the upper 284 against the last 280 and the top segments of the lasting straps 290, which extend upwardly of the insole 282, are forced inwardly to provide inwardly directed back-up forces that fold the top segments of the lasting straps downwardly and inwardly of the insole periphery to cause the upper margin 292 to be folded downwardly about the periphery of the insole, part way towards the insole, to form an acute angle with the insole. In this position, a hold-down 293 (FIG. 4) operated by an air operated motor 295 may bear against the insole 282 to hold the shoe assembly in position.

Referring to the schematic representation of a portion of the machine control circuit shown in FIG. 14, the motor 22 is retained in its idle position by pressurized air passing from a manifold 294 through a line 296, a valve 298 and a line 300 to the rod end of this motor. At the beginning of the cycle of the cement applying mechanism, a manually actuable valve 303 is momentarily shifted to permit pressurized air to pass from the manifold 294 through the valve 303 and a pilot line 302 to a valve 348 to shift the valve 348. Theshifting of the valve 348 enables pressurized air to pass from the valve 303 through the valve 348 and a pilot line 302 to the valve 298 to shift the valve 298. The shifting of the valve 292 causes pressurized air to pass from the valve 298 to the blind end of the motor 22 through a line 304 while the air in the line 300 is vented to atmosphere through the valve 298. This causes the slide plate 20 and the parts carried thereby, including the nozzles 148, to move forwardly until the valve actuating rod 50 engages the stop lug 88 at a position determined by the notch 62 that is engaged by the prong 64 so as to place the nozzles 148 over the widest part of the shoe assembly, indicated by numeral 305 in FIG. 15A.

The engagement of the rod 50 by the lug 88 causes the valve 46 to open. The motors 182 are retained in their idle positions by pressurized air passing from the manifold 294 through a line 306, a valve 308 and a line 310 to the blind ends of these motors. The opening of the valve 46 causes pressurized air to pass from the line 304 through a line 31 1, the valve 46 and a pilot line 312 to the valve 308 to shift the valve 308 so as to cause pressurized air to pass from the valve 308 through a line 314 to the rod ends of the motors 182 while the air in the line 310 is vented through the valve 308. This operation of the motors 183 causes the nozzles 148 to be lowered under the yieldable force of the pressurized air in the motors 182 until they engage the insole 282 in the general region indicated by number 305 in FIG. 15A wherein the nozzles are spaced from the upper margins 292 and the insole periphery laterally of the portions of the side portions of the upper margin and the corresponding portions of the insole periphery that are between the previously wiped toe end and heel end portions of the upper margin.

The motor 170 is maintained in its idle position by pressurized air passing from the manifold 294 through a valve 316 and a line 318 to the motor 170. The shifting of the valve 308 causes pressurized air to pass from the line 314 and a pilot line 320 to the valve 316 to shift the valve 316 so as to cut off the flow of pressurized air through the line 318 and cause pressurized air to pass from the valve 316 and a line 322 to the motor 170 to thereby so actuate the motor 170 as to move the yokes 166 towards each other under the yieldable force of the pressurized air and thus move the nozzles 148 outwardly along the insole 282 into the angle between the insole and the upper margin 292 until the nozzles engage the upper margin as shown in FIG. 16.

The motors are maintained in their idle positions by pressurized air passing from the line 318 through a line 324 to the blind ends of these motors. The shifting of the valve 316 shuts off the flow of pressurized air to the motors 130 through the line 324 so that the return springs 326 can move the piston rods 132 of these motors rearwardly out of engagement with the bolt heads 128 to thus enable the block 120, together with the nozzles 148, to be capable of swinging movement about the upright axis of the post 122 for reasons that are given below. Up to this time in the operating cycle, it is desirable to constrain the block 120, and thus the nozzles 148, against swinging movement about the axis of the post 122 to ensure that the nozzles are centered above the shoe assembly inwardly of the upper margins 292 when they are caused by the motor 182 to descend against the insole 282 so that, when the nozzles are moved outwardly by the motor 170, the nozzles will enter the angle between the upper margin 292 and the insole 282.

The motor 78 is maintained in its idle condition by pressurized air passing from the manifold 294 through a valve 328 and a line 330 to the rod end of the motor 78. The shifting of the valve 316 enables pressurized air to pass from the line 322 through a pilot line 332 and a flow control valve 334 to the valve 328 to shift the valve 328 after a time delay. The shifting of the valve 328 cuts off the flow of pressurized air through the line 330 and enables pressurized air to flow from the valve 328 and a line 336 to the blind end of the motor 78 to thus cause the motor 78 to raise the stop lug 88 and disengage it from the valve actuating rod 50, thus causing the valve 46 to close and enabling the motor 22 to again move the plate 20 and the nozzles 148 forwardly. The closing of the valve 46 shuts off the flow of pressurized air to the valves that had been shifted pursuant to the opening of the valve 46, but the valves that had been so shifted remain in shifted position due to inertia. The forward motion of the plate 20 and nozzles 1 48 continues until the valve actuating bar 216 engages the stop knob 210 that is in alignment with it. During this resumption of the forward motion of the nozzles 148, they are resiliently urged downwardly against the insole 282 by the motors 182 and are resiliently urged outwardly against the upper margin 292 by the motor so that they are bearing against the insole and the upper margin when they terminate their forward motion. The stop knob 210 in alignment with the bar 216 had been selected in accordance with the length of the shoe assembly and the toe lasted area of the shoe assembly so that at, the conclusion of the forward motion of the nozzles 148, the nozzles are located at the boundary between the wiped toe portion of the upper margin and the unwiped side portions of the upper margin. Since the block 120, together with the nozzles 148, are free to swing about the axis of the post 122, the block, together with the nozzles, may swing about this axis in one direction or the other should this boundary be located more toeward on one side of the shoe assembly than the other or should one nozzle arrive at this boundary before the other due to the variation in distances of the insole periphery on the opposite sides of the shoe assembly from the longitudinal center line of the shoe assembly.

The motor 102 is retained in its idle condition by pressurized air passing from the manifold 294 through a valve 336 and a line 338 to the rod end of the motor. The engagement of the actuating bar 216 with the stop knob 210 opens the valve 212 so that pressurized air may flow from the manifold 294 through the valve 212 and a pilot line 340 to the valve 336 to shift the valve 336. The shifting of the valve 336 cuts off the flow of pressurized air in the line 338 and enables pressurized air to flow from the valve 336 through a line 342 and a pressure regulator 344 to the blind end of the motor 102 to operate this motor at a speed determined by the setting of the pressure regulator 344 to thereby move the plunger 106 downwardly past the orifice 98 and force cement through the passage means 152, the check valves 163 and the passages 154 in the nozzles 148 into the angle between the upper margin 292 and the insole 282.

The opening of the valve 212 enables pressurized air to pass from the line 340 through a pilot line 350 to the left side of the valve 298 to thereby restore the valve 298 to its idle condition so that pressurized air again flows into the rod end of the motor 22 to cause the motor 22 to move the slide and the nozzles 148 rearwardly. At the same time pressurized air passes from the pilot line 350 through a pilot line 352 to the left side of the valve 348 to return the valve 348 to its idle condition. As s result of the rearward movement of the slide 20, the valve 212 closes due to the movement of the valve actuating bar 216 from the knob 210 that it had engaged, but the valves that had been shifted pursuant to the opening of the valve 212 remain shifted due to inertia.

The aforementioned shifting of the valve 308, pursuant to the opening of the valve 46 by the engagement of the lug 88 with the valve actuating rod 50, had caused pressurized air to flow from the line 314 through a line 354 through the block 236 into the bottom of the cavity 242 by way of the coupling 250 to thereby raise the cylinder 240 to bring the stop surface 257 and the valve actuating rod 262 into intersecting relationship with the cam 268. At this time, the cam is forward of the stop surface 257 and the rod 262 so that it does not intersect them during the forward movement of the plate 20. The slide 20, together with the nozzles 148, continues its rearward movement until the cam 268 engages the stop surface 257 and engages the valve actuating rod 262 to thereby open the valve 252. The stop surface 257 had been so located by the knob 222, in accordance with the dimensions of the shoe assembly and the area of the heel portion of the upper margin that had previously been wiped against the insole, that when the nozzles 148 stop their rearward movement, due to the engagement of the cam 268 with the stop surface 257, the nozzles 148 are approximately at the boundary between the unwiped side portions of the upper margin 292 and the previously wiped heel portion of the upper margin.

During the rearward movement of the nozzles from the boundary of the unwiped side portions of the upper margin 292 with the previously wiped toe portion of the upper margin to the boundary of the unwiped side portions of the upper margin with the previously wiped heel portion of the upper margin, the cement is continuously being extruded from the nozzle passages 154 into the angle between the upper margin and the insole 282, the nozzles 148 are continuously being yieldably urged downwardly against the insole 282 by the motors 182, and the nozzles 148 are continuously being urged yieldably outwardly against the upper margin 292 by the motor 170. Therefore, during the rearward cement extruding movement of the nozzles 148 they are able to remain in the angle between the insole 282 and the upper margin 292 in desirable positions for the extrusion of the cement regardless of the contour of the bottom of the insole and regardless of the contour of the insole periphery. During the rearward cement extruding movement of the nozzles 148, the block and the nozzles 148 are still free to swing about the axis of the post 122 one way or the other to compensate for one nozzle arriving at the boundary between an unwiped side portion of the upper margin and the wiped heel portion of the upper margin and thus provide the advantages discussed above in connection with the forward movement of the nozzles towards the boundary between the unwiped side portions of the upper margin and the wiped toe portion of the upper margin.

The opening of the valve 252 enables pressurized air to flow from the manifold 294 through the valve 252 and a pilot line 356 to the valve 336 to shift this valve back to its idle condition and thereby cause the motor 102 to terminate the downward movement of the plunger 106 and raise this plunger to its idle position to terminate the extrusion of the cement through the nozzles 148.

The opening of the valve 252 also enables pressurized air to flow from the valve 252 through a pilot line 358 to the left side of the valve 316 to shift the valve 316 back to its idle condition to thereby cause the motor 170 to return to its idle condition and swing the nozzles 148 inwardly away from the upper margin 292 to their idle positions. The shifting of the valve 316 also causes the motors to project their piston rods 132 forwardly against the bolt heads 128 to thereby lock the block 120 and the nozzles 148 against movement about the axis of the post 122. The shifting of the valve 316 also causes pressurized air to flow from the line 318 through a pilot line 359 to the left side of the valve 328 to shift the valve 328 back to its idle position and thus cause the motor 78 to lower the stop lug 88 to its idle position.

The opening of the valve 252 also enables pressurized air to flow from the line 358 through a pilot line 360 and a flow control valve 362 to the left side of the valve 308 to shift the valve 308 back to its idle position after a time delay caused by the flow control valve 362 to thereby cause the motors 182 to raise the nozzles 148 to their idle position. The shifting of the valve 308 also cuts off the flow of pressurized air to the cylinder 240 through the line 354 to thereby enable the springs 244 to lower the cylinder 240 to its idle position. The lowering of the cylinder 240 to its idle position lowers the flange 254 and its stop surface 257 out of intersecting relationship with the cam 268 and lowers the valve 252 and the valve actuating rod 262 so that the valve actuating rod 262 no longer bears against the cam 268 and the valve 252 is closed. The closing of the valve 252 cuts off the flow of pressurized air from this valve to the valves that were shiftedin response to the opening of the valve 252, but the valves that were shifted in response to the opening of the valve 252 remain in shifted position due to inertia. The lowering of the stop surface 257 out of intersecting relationship with the stop surface 257 enables the motor 22 to resume the rearward movement of the plate and the nozzles 148 until they reach their idle positions with the nozzles in a position to the rear of the shoe assembly so as to not interfere with the subsequent removal of the shoe assembly from the shoe support 272 and so that any cement that may drip from the nozzles will not fall on the shoe assembly.

Now the top segments of the lasting straps 290 are forced downwardly and inwardly from their FIG. 16 position, in the manner disclosed in US. Pat. application Ser. No. 227,376, to wipe the side portions of the upper margin 292 against the insole 282 and bond it thereto by means of the cement that was extruded into the angle between the upper margin and the insole. The lasting instrumentalities 277 are then moved outwardly away from the shoe assembly, the hold-down 293 is disengaged from the shoe assembly by the motor 295 and the lasted shoe is removed from the support 272.
