A MODEL MEAT MARKET.

A visit to the Palace meat market,
corner of South Spring and Third
streets, will not only make Los Ange-
lefios proud, but will open the eyes of
Northern California and eastern visitors,
to Mr.. Gassen's latest Improvements, to
his already finely appointed market, of
Vulcan refrigeratlng machine, two re-
trigerators, fan and fly. exterminator,
all operated by an electric motor. His
new refrigerator, the largest and finest
in the city, and the only one cooled by
a reirigerating machine, is beautiful
structure, with large plate glass front
and sides, through which can be seen
his fine stock of meats on storage, of
prime beef, veal, mutton, lamb and
pork, which is maintained at tempera-
ture of 40 degrees f. This stock is re-
plenished daily, go that at no time is he
obliged to cut up or sell any meat that
has not been on storage from ten to
twenty days.
In his refrigerator No. he keeps his
small cut meats at the same temperature
as the larger room. This cooling is dore
without the use of any ice by very
simple machine which Mr.. Charles Gas
sen, Jr., had the kindness to thoroughly
explain. The machine itself he ex-
plains as being Vulcan Ice or Refrig-
Grating machine which, instead of max
ing ice, the cooling or freezing agent
(anhydrous liquid ammonia), is circu-
lated at a reduced pressure through
pipes placed in the refrigerator or stor-
age room, operating as follows:
The anhydrous ammonia contained
in a receiver, under pressure of about
140 pounds to the square inch, is let
through regulating or expansion valve
to the coils of pipe placed in the refrig
orators, maintaining in them pressure
of from 15 to 80 pounds per square inch.
This pressure is maintained by the COM
pressor, whose duty is to receive this
expended ammonia, and by the heat
due to compression convert it into gas
which it expels and forces through coils
of pipe, called condenser, submerged
in water. In these coils or condenser
the gas is converted back to liquid and
enters the receiver, to be used over again,
this action being continuous. The
whole system is connected together,
to-wit: The condenser being connected
to the ammonia receiver, the ammonia
receiver to the cooling coils, the cooling
coils to the compressor, the compressor
to the condenser.
The cooling is effected by the expan-
sion due to the difference of the pressure
in the ammonia receiver of 140 pounds,
and the pressure of 15 to 80 pounds,
which may be maintained in the cooling
coils; as soon as the machinery is set in
motion the pipes in the refrigerator
commence to accumulate frost; this
frost is due to the dampness contained
N and liberated by the meats in the
room. This is all taken up by the
frozen pipes, keeping the room and it's
contents in perfectly dry state. This
dry air is the preservaut OF all animal
matter, and without it cold storage for
meats or vegetables is a failure. This
dryness can only be obtained by keep
ing temperature of from 40 to A de-
grees Farenheit, in the room. which can
only be had by direct cooling by ma
chinery.
The rotary fans which Mr.. Gassen has
erected in his shop are sure pre-
ventive against our worst pests flies.
No fly can exist under snch a whirl of
wind as they throw out Re ides making
the place a paradise to enter on our hot
summer days. This alone ought to in
tom of the public, leaving out the great
ful. cold stored meat, without which life
is misery. We are happy to state that
Mr.. Gaesen compliments highly the
Vulcan Iron works OF San Francisco,
who make specially of ice and refrig-
Grating machinery, and the general fit
ting up of markets and abbatoirs,
under whose direction his entire plant
was constructed, for which Childs &
Walton, of 11S South Main street, this
city, are the agents for Southern Cali
fornia. We hope to see many imitators
Of Mr.. Gassen.
