- the bottom of the cavity 134 is in communication with a source of pressurized air.
- a valve assembly 140 formed of three valves 142, 144 and 146, is mounted to a flange 148 that is secured to the top of the cylinder 132.
- the valve assembly 140 is offset outwardly of the cylinder 132.
- the flange 148 which forms a stop member, includes a forwardly facing stop surface 150 (FIG. 9) that is approximately at the level of the top of the cylinder 132, and a lower surface 152 to which the valve assembly is mounted.
- a beam 154 is mounted to the bearing block 22 associated with the back post 18.
- cams 156, 158 and 160 (FIG. 9) ofa cam assembly 161 that is mounted to the beam 154 are respectively in alignment with the valves 142, 144 and 146.
- the valve assembly 140 is located forwardly of the stop surface 150.
- the cam assembly 161 is so located that the cams 156, 158 and 160 respectively engage the valves 142, 144 and 146 during rearward movement of the beam 154, as described below, before the back of the beam 154 engages the stop surface 150.
- the motor 28 is so actuated as to cause the cables 34 to locate the slide plate 24 and the parts carried thereby, including the cement nozzles 70, in a rearward position with the beam 154 and the cam assembly 161 located rearwardly of the valve assembly 140 and the flange 148; the piston rods 56 are projecting out of the motors 54 under relatively low pressure so that the block 46, together with the nozzles 70, is restrained against movement about the upright axis of the post 48; the piston rods 76 are retracted into the motor 74; the cylinder 99 and the piston rod 101 of the motor 100 are extended away from each other so that the nozzles 70 are swung about the axes of the spindles 64 to positions that are relatively close to each other in positions determined by the engagement of the bars 94 with the stop bolts 102; the piston rods 114 are projected out of the motors 108 to thereby move the nozzles 70 about the axis of the spindles 58 to raised positions; and the cylinder
- Molten thermoslastic cement is caused to gravitate from the cement pot 42 through the passage means 86 up to the valves 92 in the nozzle mounts 82.
- a shoe assembly 162 comprising a last 164 having an insole 166 located on its bottom and an upper 168 mounted thereon is placed bottom down on a support 170 (see also FIG. 1) comprised of a last pin 172 and a toe rest 174 with the vamp of the shoe assembly resting on the toe rest 174 and i with the last pin 172 inserted into the thimble in the back portion of the last so that the toe of the shoe assembly faces forwardly.
- the shoe assembly 162 Prior to placement in the machine, the shoe assembly 162 had been toe lasted.
- valve actuating rod mounted for movement with the plate 24 engages a stop lug to stop the forward movement of the plate 24 and the nozzles 70 and to cause a valve 184 (FIG. to open, as shown in application Ser. No. 467,552.
- the motorsl08 are maintained in their idle positions by pressurized air passing from a source 186 through a line 188, a valve 190 and a line 192 to the blind ends of these motors.
- the opening of the valve 184 sends air from the source 186 through a line 194, the valve 184 and a pilot line 196 to the left side of the valve 190 to shift the valve 190.
- This shifting of the valve 190 vents the air from the blind ends of the motors 108 through the line 192 and the valve 190 and enables pressurized air to pass from the valve 190 through a line 198 to the rod ends of the motors 108 to thereby retract the piston rods 114 into the motors 108 and thus cause the nozzles 70 to be lowered under the yieldable force of the pressurized air in the motors 108 until they engage the insole 166 in the general re gion indicated by number 182 in FIG. 11 wherein the nozzles are spaced from the upper margin 180 and the insole periphery inwardly of the side portions of the upper margin and the corresponding portions of the insole periphery that are between the toe and heel portions of the shoe assembly.
- the motor 100 is maintained in its idle condition by pressurized air passing from the source 186 through a valve 200 and a line 202 to the motor 100.
- the lowering of the nozzles 70 causes valves 204, which are normally closed, to open.
- the opening of the valves 204 enables pressurized air to pass from the source 186 through the valves 204 and a pilot line 206 to the left side of the valve 200 to shift this valve.
- the shifting of the valve 200 enables the air in the line 202 to vent to atmosphere through the valve 200 and enables pressurized air to flow from the valve 200 through a line 208, a valve 210, a line 212, a shuttle valve 214 and a line 216 to motor 100 to so actuate the motor 100 as to move the yokes 98 inwardly under the yieldable force of the pressurized air operating under relatively high full line pressure in the line 216 and thus move the nozzles 70 outwardly under relatively high pressure along the insole 166 into the angle between the insole and the upper margin 180 until the nozzles reach the corners between the insole and the upper margins as indicated in FIG. 12.
- the opening of the valves 204 also shuts off the flow of pressurized air to the motors 54 so that the return springs of these motors retract their piston rods 56 out of engagement with the bolt heads 52 to thereby enable the motor 100 to move the nozzles outwardly.
- the aforementioned shifting of the valve 200 that had caused the pressurized air to flow through the line 208 to the motor 100 also enabled pressurized air to flow from the line 208 through a pilot line 218 and a pneumatic timer 220 in the line 218 to the left side of a valve 222 to shift the valve 222 after a time delay provided by the timer 220.
- the shifting of the valve 222 enables pressurized air to flow from the source 186 through the valve 222 and a pilot 224 to line 224 left side of the valve 210 to shift the valve 210.
- the shifting of the valve 210 cuts off the flow of pressurized air through the line 212 and enables pressurized air to flow under relatively low pressure from the valve 210 through a liiie 226, a pressure regulator 228 in the line 226 set at a pressure lower than the pressure of the air that had flowed through the line 212, the shuttle valve 214 and the line 216 to the motor 100 to cause the motor 100 to urge the nozzles 70 outwardly into the corners between the insole 166 and the upper margin 180 at a lower pressure than they had been originally urged outwardly.
- the nozzle bottoms 230 project outwardly at the longitudinal center line of the shoe assembly 162, as indicated by position A in FIG. 11, with the nozzle tips 232 pointing outwardly and laterally away from each other, the arms 78, gears and 84, nozzle mounts 82, nozzles 70 and nozzle bottoms 230 being so constructed as to enable this to take place when the piston rods 76 are retracted into the motors 74.
- the stop lug is caused to be disengaged from the valve actuating rod to thus cause the valve 184 to close and enabling the motor 26 to again move the plate 24 and the nozzles 70 forwardly.
- the nozzles 70 are resiliently urged downwardly against the incole 166 by the motors 108 and are resiliently urged outwardly against the upper margin 180 under relatively low pressure by the motor so that they are bearing against the insole and the upper margin when they stop their forward motion as described below.
- the machine control is so constructed that the plate 24 terminates it forward movement when the nozzles are located at the boundaries between the wiped toe portion of the upper margin and the unwiped side portions of the upper margin after which the motor 26 is caused to reverse its movement and move the slide plate 24 and the nozzles 70 rearwardly.
- cement is forced from the cement pot through the passage means 86, past the check valves 92 and through the passages 88 in the nozzles 70 into the angle between the upper margin 180 and the insole 166.
- the aforementioned opening of the valve 184 caused pressurized air to flow into the bottom of the cavity 134 to thereby raise the cylinder 132 to bring the stop surface 150 into intersecting relationship with the beam 154 and to bring the valve assembly into intersecting relationship with the cam assembly 161.
- the beam 154 is forward of the flange 148 and the cam assembly 161 is forward of the valve assembly 140 so that the beam 154 does not intersect the flange 148 and the cam assembly 161 does not intersect the valve assembly 140 during the forward movement of the plate 24.
- the stop surface 150 is located in a forward-rearward position that is dependent on the forward-rearward position of the heel end extremity of the shoe assembly 162 and the machine parts are so dimensioned that the nozzles 70 are located proximate to the heel end extremity of the shoe assembly 162.
- the motors 74 are maintained in their idle positions by pressurized air passing from the source 186 through the valve 146 and a line 234 to the rod ends of the motors 74. Shortly before the beam 154 engages the stop surface 150 to terminate the rearward movement of the nozzles 70, the cam 160 engages the 146 to shift this valve. The shifting of the valve 146 terminates the flow of air to the motors 74 through the line 234 and causes pressurized air to flow from the valve 146 through a line 236 to the blind ends of the motors 74 to thereby project the piston rods 76 out of the motors 74.
- This projection of the piston rods 76 by means of the connections provided by the arms 78 and the gears 80 and 84, causes flie nozzles 70 to swing inwardly about the axes of the nozzle mounts 82 through arcs of about 1 10 to position wherein the nozzle bottoms 230 lie on axes that are approximately parallel to the longitudinal axis of the shoe assembly 162 and the nozzle tips 232 point towards the heel end extremity of the shoe assembly as indicated by position B in FIG. 11.
- valve 142 is shifted by the cam 156.
- the shifting of the valve 142 enables pressurized air to flow from the source 186 through the valve 142 and a pilot line 238 to the right side of the valve 200 to thereby shift this valve back to its original position so that the flow of air in the line 208 is cut off and pressurized air again flows through the line 202 to the motor 100 to thereby cause the motor 100 to swing the nozzles inwardly and towards each other until the bars 94 engage the stop bolts 102.
- the shifting of the valve 142 also causes the motors 54 to return to their idle positions.
- the shifting of the valve 142 also enables pressurized air to flow from the line 238 through a pilot line 240 and a pneumatic timer 242 in the line 240 to the right side of the valve 190 to thereby shift this valve back to its original position so that the flow of air in the line 198 is cut off and pressurized air again flows through the line 192 to the motors 108 to cause the motors 108 to return to their idle positions to thereby raise the nozzles 70 to their idle positions after a time delay imparted by the timer 242.
- the valve 144 Shortly before the rearward movement of the nozzles 70 is terminated by the engagement of the beam 154 with the stop surface 150, the valve 144 is shifted by the cam 158 to cause the termination of the extrusion of cement through the nozzles 70.
- each of the nozzles 70 is caused to move rearwardly in a cement applying stroke between an initial location at a boundary between an unwiped side portion of the show assembly 162 and the previously wiped toe portion of the shoe assembly and a final location at the heel end extremity of the shoe assembly.
- a portion 250 of the nozzle passage 88 which extends radially of the upright axis about which the nozzle is swung by the motor 74, acts as a cement flow directing means that directs the flow of cement from the nozzle radially of the axes.
- the motor 74 so constrains the nozzle that the cement flow directing means 250 is directed laterally of the rearward direction of movement of the cement applying stroke and outwardly of the upright axis of swinging movement of the nozzle.
- the nozzle 70 arrives at an intermediate location wherein the heel portion of the shoe assembly commences to curve rearwardly and inwardly as determined by the engagement of the actuating member formed by the cam with the operating member formed by the valve 146, the motor 74 is actuated to swing the nozzle 70 rearwardly and inwardly so that the cement flow directing means 250 is directed generally rearwardly of the upright axis of swinging movement of the nozzle 70 at the conclusion of the cement applying stroke.
- the nozzles 70 are continuously being urged downwardly against the insole 166 by the motors 108 and, until the valve 142 is actuated, are continuously being urged outwardly against the upper margin by the motor 100, as shown in FIG. 12, while cement is continuously being extruded from the cement flow directing means 250 through openings 246 (FIG. 7) in the nozzle bottoms 230 into the angle between the upper margin 180 and the insole 166.
- the nozzle bottoms 230 and the cement flow directing means 250 are extending substantially at right angles to the sides the insole periphery and are able to remain in the angle between the insole 166 and the upper margin 180 in desirable positions for the extrusion of cement regardless of the contour of the bottom of the insole and regardless of the contour of the insole periphery.
- nozzles 70 move rearwardly past the intermediate locations and the regions 244, they are swung inwardly towards each other and rearwardly about the axes of the nozzle mounts 82 so that the nozzle bottoms 246 and the cement flow directing means 250 will continue to extend substantially at right angles to the insole periphery during the movement of the nozzles from the regions 244 to the heel end extremity of the shoe assembly.
- the cement extrusion through the nozzle openings 246 into the angle between the upper margin 180 and the insole periphery 166 continues until the nozzles arrive at the B position of FIG.
- the side lasting instrumentalities 178 are, in the manner disclosed in application Ser. No. 467,5 22, caused to wipe or fold the side portions of the upper margin 180 against the insole 166 and bond these portions of the upper margin to the insole by means of the previously applied cement and then move out of engagement with the shoe assembly.
- heel wipers 248 FIGGS. 1, 2 and 11A
- the flow of pressurized air to the cylinder 132 is cut off to thereby enable the springs 131 to lower the cylinder 132 to its idle position to thereby lower the stop surface 150 out of intersecting relationship with the beam 154 and to thereby lower the valve assembly 140 away from the cam assembly 161 so as to enable the conventional return springs in the valves 142, 144 and 146 to shift these valves to their original positions.
- the lowering of the stop surface 150 out of intersecting relationship with the beam 154 enables the motor 26 to resume the rearward movement of the plate 24 and the nozzles 70 until they reach their idle positions. After this the machine parts that have not already done so are returned to their idle positions and the machine cycle is completed so that the lasted shoe assembly 162 can be removed from the machine.
- the invention has utility wherein only one nozzle is caused to move rearwardly for applying cement and/or wherein the cement is applied to a different workpiece.
- the invention can be utilized in applying cement into the angle between an upper margin and an insole periphery of the toe portion of a shoe assembly having a rounded toe wherein first one nozzle applies cement along one side of the shoe assembly and then a second nozzle applies cement along the other side of the shoe assembly.
