element of length sufficient to extend from the middle
of a pole of the other element to the middle of a succeeding
pole, and across the intervening space or spaces. (5.) A
vacuum-tube lighting apparatus comprising in combination
an alternating - current dynamo whose rotating element
consists of a mass of iron terminating in unwound polar
projections or teeth which in their rotation act upon suit-
able generating coils, and lamps consisting of glass tubes or
other forms of receptacle containing only rarefied air or
other gas, and provided with exterior conducting-caps or
electrodes, connected directly or indirectly with the generat-

(6.) An electric-lighting apparatus comprising an alternating
dynamo whose rotor consists of a revolving mass of iron ter-
minating in unwound polar teeth or projections which ope-
rate upon fixed generating-coils, a transformer whose primary
is joined to the said generating-coils, and a secondary for
said transformer joined to lamps which consist of sealed
glass tubes or other forms of receptacle containing rarefied
air or other gas, and provided with exterior conducting-caps
or electrodes. (7.) In an electric-lighting apparatus, the
combination of an alternating - current dynamo, electric
lamps consisting of sealed glass tubes or other forms of
receptacle containing rarefied air or other gas, and provided
with conducting - caps or electrodes, the lamps being con-
nected directly or indirectly with the dynamo, so as to be
excited by the alternating e.m.f. thereof, and an adjustable
inductance connected to the circuit of the machine and
lamps. (8.) As a means for producing illumination by the
agency of electricity, the combination substantially as de-
scribed of vacuum-tube lamps having terminals of the cha-
racter described, and an alternating-current dynamo con-
nected directly to said terminals, and exciting said lamps to
luminosity by the uninterrupted or continuous application
of the alternating electro - motive force generated by said
dynamo as and for the purpose set forth.
