This invention relates to devices for use in: anism. A piston 9 provided in the cylinder 8
effecting the electro-deposition of metals in ac
cordance yvith the known method of operation
is adapted to be reciprocated by means of the
rod iii, bell-crank lever ill and push rod l2, the
wherein an electrode formed from the metal to . latter being provided with a knob i3 for con
venience of operation by the thumb of the hand _

and encloses a spring l5 which co-operates with '
the push4rod°i2 and functions to cause the de
