Patent GB-846813-A (GB)
Title: Dryer control systems
IPC: D06F58/38
Filed: 1958-10-30
Abstract: 846,813. Tumbler driers.. RANCO Inc: Oct. 30, 1958 [Nov. 4, 1957], No. 34805/58. Class 34(2)  A tumbler drier is controlled through a timer motor 10, Fig. 1, and associated cams 13, 14, actuating respective motor and heater switches 18, 19 and timer motor switch 36 such that the drier operates for eight minutes irrespective of any actuation of thermostatic bulb elements 48, 49 placed in the drier's air discharge outlet 51. During this time, the switches 18 and 19 controlling the drier drum and fan motor 70 and heater 66, respectively, are held closed by the cam 13 whilst the timer motor switch is held on by the cam 14. Whenever the air temperature in the duct 51 reaches 180 F. the expanding fluid in the bulbs 48, 49 actuate plungers 46, 55 such that a lever 53, pivoted at 54 to the plunger 46, rises to actuate toggle switch 57 to de-energize the heater 66 through opening contacts 58, 59, the contacts only re-closing when the temperature has dropped to 140F. After operating eight minutes the motor 10 is stopped through a member 41 associated with the switch 36 engaging a detent in the cam 14 to open the switch. If the air temperature in the duct 51 is rapidly rising due to the completion of the drying operation in the drier's drum the fluid in the bulbs 48, 49 actuates the lever 53, the plunger 46 moving more rapidly than 55 as the bulb 49 is thermally lagged and accordingly has a slower response to the air temperature. The lever thus tilts and closes contacts 63, 64 which effects re-start of the timer motor 10 to allow the cam 14 to again close the switch 36 whilst the cam 13 effects opening of the heater circuit one minute after the re-start and shuts the drier down altogether four minutes after the re-start through the actuation of a member 21 - which operates the switches 18, 19 - by cam detents 33 and 30 respectively. If on the other hand, the air temperature in duct 51 is not sufficient to actuate the lever 53 after eight minutes, then drying proceeds until a rapid temperature increase occurs when the lever 53 closes the contacts 63, 64 with the result described above. The control system may be used in a gasheated drier. In such a case the heater 66 is replaced by a solenoid-operated valve for controlling the gas burner. Specification 755,662 is referred to.
