IMPROVEMENT IN APPARATUS FOR THE MANUFACTURE OF ICE.
Specification forming part of Loetters Patent No. 118,649, dated Angust 29, 1871.To all s7hoa it fmay concern:
Be it known that I, JAEms E. SEIARS, of WaTeo
in the county of MeLiennan and State of Texas,
have invented certain new and useful Improve-
ments in the Manitfaeture of Ice; and I do here-
by declare that the following is a full, clear, and
exact description thereof, efreece being had to
the accompanying drawing making part of this
specification, in which-
Figure 1, Plate 1, is a top view of the appa-
ratus with the cistern for water removed. Fig.
2, Plate 2, is an elevation of one side of the ap-
paratns. Fig. 3, Plate 3, is a side elevation of
the apparatus looking at it from another point.
Figs. 4, 5, and 6 are views, showing the construe-
tion of the freezing-chest.
Similarletters of reference i dicate correspotnd
ing parts in the several fign:res.
This invention relates, in part, to certain im-
provements on machinery for the manufacture
of ice, wherein are employed one or more ex-
hausting-pumps for effecting the rapid. vaporizea-
tion of highly-volatile fluids in a freezing-chest.
The invention also relates to a novel mode of
treating volatile fluids, whereby they are made
much lighter andmorehighly volatile, and where-
by fluids are made available in the manufacture
of ice, which are more easily reclaimed than fluids
which have hitherto been used for this purpose.
The following description of my invention
will enable others skilled in the art to under-
stand it.
In the accompanying drawing I have repre-
sented two double-acting pumps, A .; but, if de-
sired, a single pump ntay be used. These pumps
are mounted upon a snbstanti l foundation, anid
their cylinders incased by jackets J J, which form
water-chambers around them. through which
chambers water is caused to flow constantly.
The water is conducted into said chambers liom
a vessel, C', by means of pipes s' vi, and flows
out of the chambers through outlet pipes v1. In
this way the pump-chambers are kept cool, and
the fluid which passes through therm will not bee
vaporized in them. Those smuiaces of the pumps
which are exposed to the fluids used for refi-ig-
crating should be constructed of materials which
will not be readily oxidized by acids, and to this
end I propose to make the pump-cylinders of
bronze metal, and the packings I make of leador copper, while the stuffing-boxes are filled with
gutta-percha. If desirable, the cylinders of the
pumps may be made of cast-iron lined interiorly
with some non-corrodiblematerials. lisingfroom
the upper heads of the pump-eylinders are two
g-uide-rods for the cross-heads t of the piston-
rods I, which cross - heads are connected to
cranks F' on a horizontal shaft, Hit. The shall
HI is Imounied in journal boxes upon a flame, H,
as shown in the drawing and is driven by imeatns
of a belt passed around the wheel 1' and arny
convenient power may be applied to turn it.
From the pumps A pipes a extend to valve-boxes
a', and from these valve-boxes extend arched
pipes B B', so that the exhaust-valves of both
pumps are connected together by a pipe, B', and
the repulsing or outlet-valves of both pumps are
connected together -by the pipe B. The arched
pipes B ' are provided with cocks bb b ' b',
which will allow communication to be cut off
when it is desired to use only one of the pumps.
The arched pipe 1 is in conununication with a
worm-pipe, C ,'in vessel C', by means of a pipe,
C, and the arched pipe B', for the exhaust. is in
coniuniuicaition with at worm, G, in a vessel, GC,
by means of a pipe, G. The cooler GU is sup-
plied with water by means of a pipe, , leading
out of aa elevated reservoir, t, and cool wetter
is drawn therefrom by means of a cook, r. The
worm in this cooler communicates with cham-
bers formed in the freezing-chest by means of a
pipe, g', to which a valve, g , is applied. The
liquelier Ci is supplied with a constant stream
of water from the reservoir R1 by means of a
cockl, , whose discharging capacityis just double
that of boti the pipes c., c, which conduct water
into the ehamnibers that sraround the punp cyl-
inders. A valve, c, is applied at the junction of
the pipe C with the worm C, and the lower end
of this worm extends out of the liquefier, and
communicates with the upper end of a vessel,
D, by means of a valve, C'.
The vessel D is designed for containing the
refrigerating fluid, hereinafter explained, and
this vessel is in communication with the cham-
bers of the freezing-chest by means of a pipe, e,
and valves l y nld e. On top of the vessel D) is
a valve-box, to which a pipe, i, is connceted,
leading into the upper end of a carbonic-acid-
gas purifier, N'. There is also an indicator, j,
