Improvements in Apparatus for Extracting Grease, Grit, and the
like from Exhaust Steam.
I, WARREN WEBSTER, of No. 491 N. Third Street, Philadelphia, Pennsylvania,
United States of America, Manufacturer, 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 :-
My invention relates to apparatus for extracting grease grit and the like from
exhaust steam so as to leave the latter comparatively clean and dry for any use to
which it may be subjected.
The said invention embodies a receiver or vessel and a trap therein of the form
of channelled or guttered plates against which the steam impinges, and by which.
the heavier matters thereof are caught, as will be hereinafter set forth.
In the accompanying drawing,
Figure 1 represents a perspective view of an extractor embodying my invention.
Figure 2 represents a central vertical section thereof.
Figure 3 represents a perspective view of the interior thereof detached.
Figure 4 represents a perspective view of one of the plates of the trap drawn to
an enlarged scale.
Figure 5 represents an end view of the plate shown in Figure 4.
Similar letters of reference indicate corresponding parts in the several figures.
A designates a vessel or receiver provided with a pipe B for the inlet of steam,
and a pipe B for the outlet of the same.
Within the vessel is a trap or baffle formed of vertical plates C, which are
connected at top and bottom with perforated diaphragms D, D said plates having
their edges bent back in opposite directions, so as to form channels E, E.
At the bottom of the vessel A is a discharge opening F, below which is a
branch G, having a cock H, said branch having also connected with it the gauge
or column J, which is in communication with the vessel A for the purpose of
indicating when the latter is completely drained or when no water is contained
therein.
The operation is as follows:-
Steam is admitted into the vessel and thus impinges against the plates C,
whereby the heavier matters such as oil, grease and grit are caught or trapped by
the gutters or channels of the same, while the steam which is thus left in dry and
clean coudition escapes from the vessel through the pipe B' and may be directed to
a place of service or use elsewhere.
The oil and grit flow down the respective channels or gutters E, and so reach
the outlet F and branch G, by which latter they are removed from the vessel, and
they may be collected by any suitable means.
The water of condensation may also escape with the oil and grit, and the latter
may be separated from the former in any desired manner.
As the channels or gutters E are on opposite sides of the baffle or trap plates, it
is evident that the device operative if steam is admitted into the vessel through
the pipe B and discharged through the pipe B, the reverse of that previously
described.
The plates C converge from the top to the bottom diaphragms, so as to gather
at or near the outlet F.
The trap as formed, is skeleton in character, and of light weight, requiring little
material in its construction. The upper diaphragm rests in the receiver above the
inlet and outlet pipe, so that the plates which are separated from each other can
have unobstructed action.
►

page_text: Owing to the converging form of the plates C, the oil, grit, or the like are
directed from the widened top of the vessel A, to the narrow end thereof, where
the outlet. F exists, the base of each gutter formed by said plates thus being in
communication with said outlet.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. An extractor for the purpose set forth having channelled baffle or trap plates,
and a vessel provided with inlet and outlet pipes, substantially as described.
2. An extractor for the purpose above specified consisting of a steam receiver
having inlet and outlet pipes on opposite sides and a discharge opening in the lower
end thereof, and a trap within said receiver formed of vertical plates connected at
top and bottom with perforated diaphragms, said plates having a gutter or gutters,
and the parts being combined substantially as described.
3. A stean receiver with a skeleton trap formed of separated vertical plates
having edges forming gutters, and perforated diaphragms, and inlet and outlet
passages between said diaphragms, said parts being combined substantially as
described.
4. In an extractor for the purpose set forth, channelled baffle or trap plates, in
combination with a containing vessel provided with inlet and outlet pipes, and a
discharge opening, said plate converging at said discharge opening, substantially as
described.
