  • Patent number: 4546235
    Abstract: In a device for melting and dispensing measured amounts of a thermoplastic adhesive, the adhesive is melted in a housing having a handle with a pistol-like grip. Two separate heating stages are provided in the housing, a higher temperature heating stage for use during operation and a lower temperature heating stage effective when the operation of the device is temporarily interrupted. A control member, such as a sensor, is provided in the handle so that when it is gripped by an operator, and the device is connected to a power supply, the sensor switches over to the higher temperature heating stage. With the device connected to the power supply, but the handle and the sensor not gripped by the operator, only the lower temperture heating stage is effected. If there is a temporary interruption in use, and the handle is released, the sensor effects a changeover from the higher temperature heating stage to the lower temperature heating stage.
