An Improved Arrangement for Removing Grease from the Condensers
of Carbonio Acid Refrigerators.
1, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
It is well known that is the use of carbonic acid refrigerators the grease
employed in the compressor, such as glycerine or the like, is, after a time carried
over into the condenser and collects at the hottom thereof thus necessitating the
removal of the same.
This proceeding has hitherto been attended with considerable inconvenience
while the spiral of the condenser is submerged in water, and the opening of the
joint consequently is. impossible and besides such arrangement for the removal of
the grease will altogether weaken the spiral condenser.
This inconvenience will be obviated by means of the present invention which
enables the grease collected at the bottom of the condenser to be removed through
a valve arranged in the pipe rising from the condenser, the said valve enabling
communication to be established with the interior of a pipe inside the tube of
the condenser and extending to the lowest point of the same.
In the accompanying drawing
Figure 1 is a vertical section of the improved arrangement, and
Figure 2 is a side elevation of the same.
In the drawing the pipe a rising perpendicularly in the condenser is shown
broken so that only the uppermost and lowest part of it can be seen, the latter
being supposed to be continued in the ordinary pipe-spiral.
With the flange 6 of this pipe corresponds another Hange e having a top piece
or extension with a central bore or chamber, the said flanges being secured together
by bolts d. The said chamber or bore in the top piece communicates by means
of two pipes e and f respectively with the regulating valve for the fluid carbonio
acid and a manometer. At the top, the bore or chamber is closed but is continued
by a smaller opening which receives the end of a pipe of corresponding diameter,
extending down through the tube of the condenser and deflected at its lowest
point as at n.
Communication between the interior of the tube of the condenser and small
opening in the said top piece is consequently only possible through the pipe /
the said opening or channel being normally kept closed by the valve g which is
pressed against a corresponding seat by a nut h.
When the nut h is loosened the pressure from the inside will raise the valve
and the fluid from the pipe will pass through the two holes or perforations i in
the valve, connected to a single passage or hole leading to a bent pipe m com-
municating with the open air.

page_text: It is therefore possible with the above. described arrangement to remove the
grease which, may collect at the bottom of the condenser, by the mere turning of
the nut h, which is very easy of access, and without weakening the condenser tubes
themselves by attaching screw-tops or the like.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondents, I declare that what I claim is:-
An arrangement for removing grease from the condenser of carbonic acid refri-
gerators consisting of a top piece or extension closing at the upper end the pipe a of
the condenser, provided with a pipe e for carrying off the fluid carbonic acid, and
a narrower pipe extending within the pipe a to the lowest point of the condenser
while the uppermost end can be closed, by means of a conical valve g adapted to be
secured by a nut h, as described.
