Abstract: <PICT:0702626/IV(c)/1> <PICT:0702626/IV(c)/2> <PICT:0702626/IV(c)/3> <PICT:0702626/IV(c)/4> <PICT:0702626/IV(c)/5> <PICT:0702626/IV(c)/6> <PICT:0702626/IV(c)/7> In a machine, in which textiles such as hosiery are introduced into a chamber and subjected to a treating medium for a predetermined period and thereafter to a circulation of drying air, the textiles then being withdrawn from the chamber, the treatment cycle is operated by a control mechanism.  Automatic finishing boarding and drying cycle.  With the door 2 open, Fig. 29, fresh stockings are mounted on the forms F, Fig. 1, on expanded carriage 13, the carriage 12 being collapsed in front of the treating chamber 1.  Selector switches 140, 140a, are set as in Fig. 7, the operator pressing start button 141 which causes relay 131 to lock up. Relays 134, 125 and 130 operate to cause conveyer motor 21 to start which rotates pinion 17 in engagement with rack 16 to displace the carriages 12, 13 to the left, expanding the former and collapsing the latter.  The opening of limit switch 123 releases relays 125, 134 back contacts of relay 125 causing relay 126 to operate.  As carriage 12 nears the end of its travel, limit switch 122 moves over, releasing relay 130 so that the conveyer motor 21 stops while the closing of the back contacts of relay 130 causes relay 127 to operate and door motor 9 to run.  The carriage 13 is displaced into the treatment chamber 1, Fig. 30, and as the door 2 closes safety switch 146 opens and limit switches 120, 121 change over to operate timer 138.  The operation of the relay causes the motor 139 to run and contacts c to close so that relay 132 operates, solenoid 27 actuating valve 26, Fig. 2, shutting off the exhaust through pipes 25 and 30. Operation of valve 26 also permits live steam from pipe 28 passing through pressure regulator 29 to pass through pipe 25 to the chamber 1, the build-up of pressure operating switch 147.  At the end of the steaming period, contacts c open to release relay 132, valve 26 cutting off the steam supply and allowing the steam in the chamber to pass out through pipes 25 and 30.  The fall in pressure in the chamber causes switch 147 to close and completes a circuit over contact b, 138 to operate a relay 133, which sets a timer 136 into operation and also, through solenoid 98 changes over valve 97.  Steam passing through regulator 106, valve 97 and flexible hoses 197, 198 causes a piston to move in cylinder 45, Fig. 4, to open inlet and outlet ports 35, 36.  When the timer motor 137 causes contacts c to close, relay 135 operates so that the air circulating fan 57 runs, solenoid 88 opening a valve to allow steam to pass through normally open valve 95, pressure regulator 92 and pipe 85 to radiators 60, 61, 62 arranged at the back and base of the treatment chamber.  Air is then blown into the chamber by fan 56 and heated by passage over the radiators, the air passing out through port 36.  At the completion of the drying period, contacts b, 136 close and c open, relay 135 releasing to stop the fan motor 57 and close the radiator steam valve 88.  Relay 128 operates, releasing relay 133 so that timer 136 stops and solenoid 98 is de-energized to return valve 97 to normal and close the air ports 35, 36.  The operation of relay 128 also causes the door motor 9 to run in reverse to open the door, limit switch 120 returning to its normal position and thus breaking the circuit to timer 138.  Near the end of the door travel, limit switch 121 opens to release relay 128 so that the door motor 9 stops.  In the fully open position, Fig. 31, switch 146 closes, relays 134 and 129 pull up, the conveyer motor 21 running in reverse to carry the carriages back into the initial position shown in Fig. 29 where the limit switch 123 changes over. While one batch of stockings is undergoing treatment, the attendant removes the treated stockings from the other frames.  If further time is needed the stop button 142 may be pressed.  When steaming alone is required the right-hand contacts of selector switch 140 are changed over, Fig. 17 (not shown).  For continuous automatic drying, valve 95 is closed and valve 96 opened and the left-hand contact of selector switch 140 is changed over Fig. 20 (not shown).  For semi-automatic operation the selector switch 140a is changed over Fig. 23 (not shown).  The attendant presses start button 141 and then button 144, the machine continuing to function until the position of Fig. 31 is reached.  Button 143 is then pressed and the cycle continues until the position of Fig. 29 is reached.  The cycle is made for steaming or drying according to the position of selector switch 140.  Specification 568,946 is referred to.
