I JOSEPH DIXON, 95 Fifth Avenue New York, U.S.A. Commission Merchant, do
hereby declare that the nature of my invention for AN IMPROVEMENT IN AERATING
DEVICES FOR AERATING LIQUIDS, 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 an improved Aërating Device for aërating ale, beer, cider,
lemonade, milk and other drinks and causing them to foam and effervesce, which device
may be made of metal, glass or other material.
The construction and operation of my invention in its preferred form are shown in
the accompanying drawings, which are hereby made a part of this Specification.
Figure 1 represents a cross section of the Device with part broken away to show
working parts.
may
Figure 2. represents a top view of a thin plate of metal, or other material which
be made flat or curved and of any desired shape and dimensions so as to be adapted to
fit vessels of various shapes and sizes containing liquid to be operated upon. G. is the
plate perforated with an opening H (see figure 1) which may be of any shape, and a
number of other openings c c. Springing from and completely surrounding the edge
of the opening H projects a cap A, of any desired shape, having an opening Bat
the top.
In figure 1 D represents a tube open at both ends which may be of any desired
length and interior diameter; frepresents a check-valve which may be of any desired
form, from the upper part of which project one or more curved or bent and elastic
tongues d. d. so constructed as to pass through the opening H, in the plate G, into and
through the cap A, and the opening B-When the tongues d. d. have passed through
the opening B, they spring outward and catch on the sides of the opening B and
prevent the check-valve from falling out through the opening H and keep it in place
within the cap A, while at the same time allowing the check-valve f to play freely up
and down inside the cap A.
To construct my invention in the form above described, and shown in figure 1, I
push the upper part of the check-valve through the openings H, and B, until the
tongues d. d. spring outward and catch above the opening B-I then by solder or

page_text: other suitable means attach the tube D to the plate G, the opening in the lower end of
the tube being large enough to fit over the cap A-The check-valve fis made to
fit loosely in the cap A, so that it rises and falls alternately when the Device is in
operation.
The action of my Improved Acrating Device is as follows:-
The liquid to be aërated having been placed in any suitable vessel the operator inserts
the Device into the liquid and works it lightly and rapidly up and down with each
upward stroke air rushes downward through the mouth of the tube towards the bottom
of the vessel and flows instantly upward permeating all through the liquid; with each
down stroke the check-valve closes the opening H, and prevents the inflow of the
liquid into the tube: the openings c. c. allow the air to escape upward and permeate
the liquid. Instead of the tongues d. d. a perforated washer I, as shown in figures 3
& 4.may be employed for keeping the check-valve in place. Í do not confine myself
to any particular form of check-valvo.
Having now particularly described the nature of my said invention and in what
manner the same is to be performed, I declare that what I claim is :-
1. As an Improved Aërating Device the combination of the tube D, and rigidly
attached thereto, the perforated plate G, with the opening H, the cap A springing
from the edges of the opening H and open at the top B, and the check valve f
adjusted to play up and down through the opening B and the cap A, and provided
with tongues d. d. or with a perforated washer I adapted to hold said check-valve in
place all substantially as set forth.
2. In an improved Aerating Device the combination with a tube of suitable length
and interior diameter open at both ends and rigidly attached to a perforated plate
of any desired shape and dimensions, which plate has a central opening beneath the
end of the tube, of a cap or ring springing from the edges of such central opening
and projecting into the tube, such cap or ring having openings at top and bottom,
and a check-valve adjusted to play up and down freely inside the cap or ring, and
provided with suitable means for holding said check-valve in place, substantially as
set forth.
Dated this 2nd day of February 1887 at New York, United States of America.
