An electrically powered squeezer such as a caulking gun for dispensing a viscous substance such as a caulking or sealing compound. The gun comprises a housing carried by an operator and incorporating an electric motor and a switch for energizing and deenergizing the motor. The housing is formed with a holder for receiving therein a cartridge filled with the above viscous substance and having a discharge nozzle. Incorporated within the housing is a pressing element driven by the motor to compress the cartridge wall so as to force the viscous substance out of the cartridge through the nozzle. A release mechanism is included to disengage the driving connection between the motor and the pressing element when the switch deenergizes the motor, in such a way as to allow the pressing element to retract to a position where the pressing element no longer exerts pressure upon the viscous substance. Accordingly, when the squeezing of the viscous substance is interrupted, the consequential retraction of the pressing element releases the residual pressure in the viscous substance remaining within the cartridge which developed in the previous squeezing by the pressing element, thus preventing the viscous substance from drooping or oozing from the nozzle.

An extruder for a fluid material including a cartridge containing a fluid material, and pushing members for pushing an end of the cartridge so as to extrude the fluid material. The pushing members are arranged to be driven by a system of a pinion and racks put in motion through reduction gears.

A hair cutter for thinning hair which includes a stationary blade, a movable blade, a comb member adjacent to either the movable blade or stationary blade, and a hair pressing member disposed on the side of either the stationary blade or movable blade where the comb member is not located. This arrangement permits hair to be thinned easily and accurately even when used by individuals lacking a barber's hair cutting skill.
