BY constructing the machine in the form shown
in figure there is obtained electric motor capa-
BILE OF performing light work. such running sew
ing machines ana pumping water. 1t forms part Of
the inventors system and may be used either with
or without the electric light. To ordinary
sewing machine it req uires only much electricity
necessary to give out electric light Of the
strength OF . common gas Jet. To put 1t in opera
ton on q sewing machine the housewife has merely
to attach 1t by little belt at with the wheel OF
the sewing machine. and turn on the electricity by
touching little knob conveniently attached. The
cost is the if she burning ono electrio

THE ELRcrRoMETER
Theapparatus for measuring the amount Of cleo
tricity used by each householder is simple contri
consisting OF electrolytic cell and . small
coil OF wire. appropriately arranged in . box. tho
latter being of about half the size of ordinary gas
meter and like gas meter it can be placed in any
part Of the house. The measurement is obtained by
the deposit Of copper particles little plate in the
electrolytic CELL such deposit being caused by the
electric current passing through the CELL the end
of any period, say month. the plato is taken by
tho inspector the central office. where tho copper
