Abstract
A device, noteworthy by its compact construction, portability and use of a constant torque spring to dispense liquid under a uniform force, in which binding due to possible rotative movement in the slide that is powered by the torque spring is obviated, so that the slide tracks properly during liquid-dispensing service of the device, This is in contrast to torque spring-operated prior art devices in which special precautions were required to neutralize the turning movement unavoidably resulting when the torque spring assumed its characteristic helical coils during its functioning.
