AN EFFICIENT AND SAFE GAS MACHINE PRODUCING

SIR American petroleum and American
lamps giving beautiful and comparatively mex
pcnsive light, are among most important contrbu-
lions to civilization But ike other OF natures agencies
which man utilities, petroleum is dangerous servant.
Tho kerosene lamp is constant fountain OF calamity
as a fame brought into close contact with an explosive
fluid must necessarily be. The best method or making
available the admirable Illuminating qualities OF petro
leum il TO convert it into vapor Hydrocarbon
gas is the most perfect ght-givng material yet
Freed from every foreign element brought to any de-
sired point In any desired quantity, 1t burns with
brilliant white fame, leaving no resduum. making

carbon gas taxed the ingenuity OF inventors during
the past 20 years A good gas at low cost, has been
easily made and innumeraOle undertakings have sue
ceeded far, under favorable conditions; but
late the supply OF such gas under all conditions, to
proved impossible The principal difficulty has been
would evaporate the more rapidly, leaving the main
body growing con 'taotly poorer; the gas produced
being rich and smoky at first and gradually turning blue
and faint as inc process continued furthermOrc. tne
devices employed to make the have been constructed
principles necessarily involving danger. and many
accidents have consequently ensued
The state OF the case respecting artificial light may
be summed up in the form >of problem as follows
Given suitable material TO mud means for converting IL
into illuminating gas OF uniform good qnality without
danger with s least possible h SS5 r at the

automatic gas apparatus, which received tho prize
az the Franklin Institute Exhibition in this city. IL
called tue Keystone Safety Gas Machine. and " Is
tainly very simple In construction aud operation, and
produces pure white hgnt soft, pleasant, and yet
brilliant Safety Is secured in the use of this apparatus
by placing the entire mechanism In vault, apart
the premises TO DO lighted, no connection what
ever being mado Herewith except the gnssupply
pipe. There IS heat or light required In the process
l. TO enter the vault, and there Is
nothing but the gas pipe In the building lighted. Tue
important claim made for the machine Ia that IL

fractional portion OF the gasmang material Is taken
up from the bottom OF the reservoir and carried 10 the
eyaporang surfaces. BY this separation the main body
