SPECIFICATION formihlg part-of Letters Patent N2o 342. 543. dated aMay 25, 18i6.
A p tlieatiwavl ed M Iar h 10. 1 -0. S iial N o . 19:, M N , . .... .To all wT~oit it t may contcel7L:
Be it known that I, JACOM Scenti;ul., a
citizen of the United States, residing" at San
Antonio, in the county of Bexar and State of
5 Texas, have invented certain new aind useful
Im iprovements in Ice - Machines; and I do
hereby declare that the following is a full,
clear, and exact description of the same, iref
crepce being had to the annexed drawinlgs,
io making a part of this specificationll, an to
the letters and figures of relfdrence ilmarked
thereon.
Figure 1 of the drawings represent a side
elevation of my invention, partly in section
15 and Fig. 2, a vertical section of thecompressor
and onleof the oil-interceptors on an enlarged
scale, with the several pipe - connections,
valves, &e., in elevation.
The present invention has relation to that
20 class of ice-machines wherein a liquefiablegas,
preferably that of ammonia, is introduced in
.a coimpression-pump, and is compressed to a
partly state of liquefaction, tihe pressure be-
ing subsequently removed, the liquefied re-
2 frigerating agent expanding througit tubes,
ooils, tanks, or other chambers, and the frig-
orific effects produced by the volatile liquid
again assuming its gaseous state is utilized for
absorption of heat.
30 The invention therefore consists inll in il
proved arrangement of coils, combined with
successive oil-intercepting tanks, and certain
improvements in the construction of the gas-
compressor and its adjluncts, as will be here-
35 inafter described, and specifietally set forth in
the clainis.
In theaccomlpanying drawings, A represents
the compressing-cylinder containing oil ip the
lower portion thereof, as a compression ime-
40 dium to lubricate thepistonland preventleak-
age at that.point. From the compressing-
cylinder the compressed and partly-liquefied
gas passes through the pipe a into the top of
the vertical cylindrical oil-intercepter B, and
45 thence through the vertical pipe b into one end
of asecond oil-intercepter,. 'lThis interceptor
C is supported in a nearly horizontal position,
but yet with the end at which the refrigerant
enters slightly higher, and the opposite end
co thereof has cotinected to its under side a pipe,
c. This pipe carries the oil that may have
passed to the interceptor C, and also anty am-Inoia 1luh l 1 m ly l1 Ne li n ,liti , to hl e liq uid-

The interceptor it has apip li, provided with
a valve, r for the purpose of to admitting oil i
the pumlr through the stulling-box, and to
regulate the supply is lttnd desirable.
The construction of the apparatus and its
operation hating been fully set forth, I will
no des ribe isore inutely the compressor.
The compressing cylinder , is provided with 8it
a jacket, K, in the lower portion of which
certain quantity of crude lubricating-oil is
kept to lubricate the piston L and seal its pe-
riphery against, the iqaterior of the cylinder.
The walls of said cylinder have in their lower 90
half a series of, \ertient slots, 3, through
which the lubricating' oil passes in and out as
the piston is in motion, and also to permit the
aillillOnnia-gas to enter the cylinder above the
piston when the latter is at the bottom of its a5
course and has dipped into the oil. The pis-
ton is provided with l-king-rings rand Ile-
ripheral grooves 8. to carry oil on its upward
movement and lubricate the cylinder. The
piston isprovided at its upper end with asuit- oo
able seat upon which rests Ihe valve N, said
valve having stems t passing loosely through
holes in the pistonand having their lower ends
attached, to a spider, O, playing on the piston-
