  • the piston rod 22 is retracted into the motor 16 so that the insole rest 60 is in a lowered position with the flange 49 located spacedly above the stud 50 and the valve actuator 56 located spacedly below the pin 46; the piston rod 64 is retracted into the motor 62 ao that the cement applicator 68 is at a lower level than the insole rest 60 as shown in FIG.
  • a shoe assembly 146 is presented bottom-down to the machine.
  • the shoe assembly 146 comprises a shoe insole 148 located on the bottom of a last 150 and a shoe upper 152 draped over the last.
  • the top of the toe end of the last has an upwardly projecting knob 154.
  • the insole 148 is placed by the operator against the insole rest 60, which thus constitutes a shoe assembly support, and the toe end of the last 150 is caused to bear against the toe bar 70.
  • all of the pincers 108 are located above the insole 148 and the margin of the upper 152 is inserted between the open jaws of all of the pincersv FIG.
  • FIG. 12 schematically illustrates a portion of the pneumatic control circuit of the machine.
  • the control for the motor 102 shown in this figure is illustrative of the controls for the motors 102 for the toe pincers assembly 94 and for those side pincers assemblies 96 that consist of the corner pincers assemblies and the forepart pincers assemblies.
  • the jaws 112, l 14 of all of the pincers assemblies are caused to grip the upper margin under a relatively heavy gripping force.
  • this is caused by shifting a valve 156which enables pressurized air to pass under full line pressure from a source 158 through the valve 156, a valve 159, a spring return valve 160, a line 162, a shuttle valve 164 and a line 166 to the head end ofa motor 102 to actuate the motor 102 to raise its piston rod 128.
  • the rise of the piston rod 128 raises the cam roll 134, which acts as a pincers closing member, so as to cause the cam roll 134 to move between the cam follower surfaces 136 and 138 and swing the jaw leg I22 away from the jaw leg 120 to thereby swing the jaw 114 against the jaw 112 with the relatively high force imparted by the full line pressure of the air in the line 166 to thereby cause the jaws 112, 114 to close and grip the upper margin.
  • the motor 16 is retained in its idle position by pressurized air passing from the source 158 through a line 163, a valve and a line 167 to the rod end of the motor 16.
  • the valve 165 is maintained in position to enable the pressurized air to flow through it to the rod end of the motor 16 by pressurized air flowing from the source 158, the line 163, a line 168, a valve 170 and a pilot line 172 to the left side of the valve 165.
  • the aforementioned shifting of the valve 156 enables pressurized air to flow from the valve 156 through a pilot line 174 to the valve 170 to shift the valve 170 and thus cut off the flow of pressurized air to the valve 165 through the pilot line 172.
  • the shifting of the valve 156 also enables pressurized air to flow from the line 174 through a pilot line 176 to the right side of the valve 165 to thereby shift the valve 165.
  • the shifting of the valve 165 cuts off the flow of pressurized air in the line 167 and enables pressurized air to flow from the valve 165 through a line 178 to the blind end of the motor 16 to thus actuate the motor 16 to raise its piston rod 16 and the parts, including the toe post 20 and the insole rest 60, mounted to the piston rod 16.
  • the shifting of the valve 170 also enables pressurized air to flow from the valve 170 through a line 180, a valve 182 and a pilot line 184 to the valve 160 to shift the valve 160 and thus cut off the flow of high pressure air flowing under full line pressure to" the motor 102 through the line 162.
  • air under relatively low pressure flows to the motor 102 from the valve 159 through a line 186, a pressure regulator 188 set at the relatively low pressure, the shuttle valve 164 and the line 166.
  • the flange 49 engages the stud 50 to thereby lower the strip 34 relative to the plate 32 which causes the pin 46 to engage the actuator 56 and thus shift and open the valve 52.
  • the opening of the valve 52 enables pressurized air to flow from the source 158 through a line 190, the valve 52 and a pilot line 192 to the valve 182 to shift the valve 182 to closed position and thus cut off the flow of pressurized air through the pilot line 184 to the valve 160 thereby enabling the return spring of the valve 160 to return this valve to open position.
  • the opening of the valve 160 enables air under the relatively high full line pressure to again flow to the motor 102 through the line 162, the shuttle valve 164 and the line 166.
  • the upper margin is gripped by the stationary pincers 108 of the toe, corner and forepart pincers assemblies diring the rise the show assembly 146, this rise being caused by the actuation of the motor 16 to raise the insole rest 60.
  • the ball pincers assemblies may be forced downwardly under relatively low pressure to force the pincers 108 of these pincers assemblies downwardly during the rise of the shoe assembly.
  • This rise causes the upper 152 to be stretched tightly about the vamp of the last 150.
  • This stretching effect is enhanced by actuating the motor 86 to project its piston rod 88 to thereby swing the insole rest 60, together with the shoe assembly 146, counter clockwise as seen in FIG. 2 about the axis of the pivot pin 61.
  • This stretching effect may also be enhanced by actuating the motors 98 of the ball pincers assemblies 96 to move their piston rods 100, together with their pincers 108, downwardly during the upward movement of the shoe assembly 146.
  • the relatively low pressure imparted by the motors 102 of the toe pincers assembly 94, the corner pincers assembly 96 and the forepart pincers assemblies 96 to the piston rods 128 during the rise of the shoe assembly 146 lessens the upwardly directed force applied by the cam rolls 134 to the upwardly convergent follower surfaces 136, 138 of the pincers 108 of these pincers assemblies to thereby relax to some extend the gripping force applied against the margin of the upper 152 by the jaws 112, 114 of these pincers assemblies thereby enabling the upper margin to slip to some extent between these jaws during the rise of the shoe assembly.
  • the last 150 of the shoe assembly 146 operated on by this machine has an upwardly projecting knob 154 at its toe end.
  • This knob creates a stress on the upper 152 being stretched about the last 150 during the rise of the shoe assembly 146 while the upper margin is being gripped by the pincers 108 of the toe pincers assembly, the corner pincers assemblies and the forepart pincers assemblies, which stress could tear or rupture the upper.
  • the motors 98 of the toe pincers assembly, the corner pincers assemblies and the fore-part pincers assemblies are maintained in their idle positions with the piston rods of these assemblies projected upwardly of their motors 98 by pressurized air passing from the source to these motors through certain of the valves 144. Should the operator find that the strectched upper 152 is not properly located on or stretched about the last 150, he may move an appropriate handle to shift the associated valve 144 which will actuate the associated motor 98 to retract its piston rod, 100 downwardly and thereby force the associated pincers 108 downwardly while the pincers is firmly gripping the upper margin under the relatively heavy force. Others of the valves 144 are connected to the ball pincers assemblies in the manner shown in US. Pat.

  • a slide plate (not shown) which carries a toe pad 198 and toe wipers 200 is caused to move forwardly to a position wherein the toe pad clamps the toe portion of the upper 152 against the last 150.
  • an arm 202 of a bell crank that is mounted to the toe pincers assembly 94 is swing clockwise as seen in FIG. 6 to swing an arm 204 of this bell crank downwardly.
  • the downwardly moving arm 204 engages a ledge 206 (FIG. 2) mounted to the toe bar 70 to thus move the toe bar and the post 72 downwardly against the force of the spring 74 to prevent the toe bar from intefering with the toe wipers 200 during the below described wiping stroke.
  • the wiped toe portion of the shoe assembly 146 is supported by the toe wipers 200 and increased pressure is applied by the toe hold-down 196 against the top of the shoe assembly 146 to thereby provide a relatively heavy bedding pressure between the now wiped-in upper margin and the toe wipers 200.
