5 an inlet 6 is constructed in the melt chamber 5 and interconnects with nozzle 11 to form an exit passage for the melted glue a ball valve not shown is constructed in nozzle 11 to prohibit the exit of glue until a predetermined pressure is present in the melt chamber 5 this is to prevent leakage of residual glue during the idling cycle of operation as illustrated in fig2 the glue rod 7 is fed into the melt chamber 5 by feed gears 12 and 13 which are driven by motors 14 and 15 respectively the feed motors 14 and 15 are turned on by a switch 16 which is mechanically actuated by trigger 17 in the handle 18 of housing 4 heaters 8 and 9 are connected to a power supply through control circuit 19 and cord 20 so that the heater circuit is energized whenever the appliance 1 is plugged into a power source the temperature of the melt body is sensed by a thermistor 21 which is embedded in the melt body 2 and the control circuit 19 is connected to regulate the heaters to a predetermined temperature the control circuit 19 also connects feed motors 14 and 15 across a power supply through switch 16 switch 16 is normally in the open position and is only closed when the flow of glue is desired upon manual actuation of trigger 17 the control circuit 19 may be of the type described in copending u s patent application ser no 735 191 filed on oct 26 1976 in the name of robert j duncan and.
