Some months since the press OF this city gave
extended mention Of Messrs Whpple Dickerson's
process for the generation OF gas from petroleum by
means Of superheated steam, and its application to
the production Of heat and light. This invention
has now taken such practical shape that the Key
stone Liquid Fuel Company, OF No. 319 Walnut
street, have organized with capital OF half mil
lion dollars and are now engaged in the manufac-
ture OF machines under this patent and the sale
of rights and royalties for the State OF Pennsylvania.
Their card will be found in our advertising columns
The practical operation Of this process to be
entirely successful. The owners and inventors have
issued a very handsome prospectus, in which we
find the following strong letter from Messrs. Bar
rows, Savery & Co., hollow. ware manufacturers, at
Front and Reed streets, in this ciiy:-
PHILADELPHIA, Pa, October II, 1S70.-Messrs.
Whippe Observation-Disclosures: We take plea
sure in saying that have had in operation our
foundry, at the Of Front and Reed Streets in
this city, for nearly six months, one of your Liquid
Fuel Machines" developing principle and process
for the conversion OF Crude Petroleum into gas
using the same as fuel for generating steam.
The results, thus far of the most satisfactory
character. Our entire machinery, consisting OF
cylinder boiler OF sixty-horse power three engines
and all the connections Herewith, has, during that
time, been operated by your machine daily, except
Sunday and some few days when the works were
stopped, without any trouble diflculty, and with
many advantages coal. When burning coal
we have been able to carry average of only thirty
five pounds steam pressure on our boiler, but with
the gas furnished by your machine we carry uni
form pressure of sixty pounds with ease, and more
II required, constant surplus of steam is ind-
Gated at the safetyvalve The very great advantage
of this result is that we find the power of our ma
chnery fully double that which can be attained with
coal under the boiler and under like conditions
Our power OF production ia therefore increased in
most gratifying degree, and we believe that in this
respect lies one OF your most profitable achieve
ments.
Many minor, but nevertheless valuable features
are the result of this fact which practical men will
especially appreciate. For instance, we are enabled
to run off our blast in much less time than is re-
quired when using coal. We can keep our boiler
full OF water-a feature of both safety and efficiency
because the power is sufficient to keep the pump
constantly working. and we find that fire for eight
hours produces heat enough to generate steam for
ten hours that the fire and fuel supply entirely
shut off one hour before noon, and one hour before
stopping at night each day. 1t requires only about
half an hour with us to raise steam sufficient to
start the engines.
We regard the machine as entirely safe remark
ably easy OF CONTROL not liable to get out Of order
and in its operations 1t is difficult conceive
Of more perfect beautiful combustion, while
smoke, ashes, and cinders are entirely done away
with 1t produces much more regular and uniform
heat than can be produced by burning COAL
We herewith give you the items OF machinery
which we are now running at our works Our boiler
is sixty inches in diameter, and twentyeight feet
long, with return hue twelve inches in diameter,
and is called by boiler makers sixty-h horse power.
We drive with it three engines. The largest has
attached to il three heavy grindstones sixty inches
in diameter and twelve inches broad on the face,
for grinding sad-irons; and two small grindstones
for finishing castings and grinding tools; two
shafts running four emery wheels; nine mills for
cleaning castings; four mills for grinding enamel
tWhlch require large power to run them); two
stamps; one rotary shears lathe; one fan for
making covers; one boltcutting machine, and one
OF McKenzies blowers, making blast for two
Mckenzie cupolas, one melting five, and the other
three tons OF iron per hour. The second engine
drives eight round and two oval athes, for turning
hollow-ware, one fan, and one grndstone. The
third engine drives small lathes and one grind
stone for pattern shop Besides, with the same
boiler, we heat by steam in winter che grinding and
polishing shops, tie cleaning shop, pattern shop,
and Office.
During the past month we have run our works to
their full capacity making clear Saving of toenty-
fue per cent. coal to make the same steam, and
fully believe that had we the machinery to utilize
the steam which this fire produces 1t would show
net saving over COAL with u.s. Of at least ffty per
eeni We have carried sixty pounds of steam,
blowing oil at the safety-valye nearly all
the time, and running all of the machinery
not being obliged to throw Off any of it,,
while with coal we could not have carried
more than thirty to thirty-hve pounds and would
have been obliged to throw Off quite large portion
OF the machinery, during the running OF the blast
but aoc we cannot tax the boiler as to reduce the
pressure below sixty pounds. We also keep three
full gauges OF water the boiler, and keep tn G
pump running all or nearly all the time, which makes
the boiler much safer. With coal fire we could not
run the pump with the blast on and we often run
the water below the lower gauge making it very
difficult to keep up steam
We give you few of the advantages over coal
which we have discovered in using your machine
for nearly six months:-
First There is no drawing of fires, which makes
the danger to our premises from fire much less.
Second. The power is increased fully double, with
the same boiler without a corresponding increase
in cost.
Third. The labor OF firing, cleaning fires, and re-
moving cinders saved and there is no dust about
the boiler.
Fourth We are able to quit at night with full
head OF water and steam, and have losses by
slack iron from the want of blastl which often
occurs with coal
Fyfh There will be no fear OF fire in case OF boiler
explosion, there Goals to be thrown around
the premises.
.Sirth Entire absence of smoke
We have been in the foundry business, principally
hollow. ware In this city, for the past thirty years.
and we confident, therefore, that the practical
advantag, of your process and machine are all that
are claimed. We cordially recommend 1t TO those
who wish for an efficient and economical motive
power and have hesitation In saying that we be-
lieVe it to be OF the greatest aud most beneficial
inventions Of the age.
Very respectfully yours,
BARROWS, SAVERY Il 90.
