Abstract
Involved is a device, noteworthy by its compact construction, portability and use of a cooperating pair of constant torque springs to dispense liquid under a uniform force, in which any binding in the slide that is urged through movement by the torque springs is obviated, so that the slide tracks properly during liquid-dispensing service of the device.
