JAMES S. McNEEL AND JAMES M. VANCE, OF SAN ANTONIO, TEXAS.
MILK COOLING'AND AERATING APPARATUS.Specification of Letters Patent. Patented Mar. 13, 1917.
Application filed October 29, 1915. Serial No. 58,628.To all whom it may concern:
Be it known that we, JAMES S. McNEEL
and JAMES M. VANCE, citizens of the United
States, residing at San Antonio, in the
5 county of Bexar, State of Texas, have in-
vented a new and useful Milk Cooling and
Aerating Apparatus, (Case A,) of which
the following is a specification.
This invention relates to apparatus for
10 cooling and aerating milk, one of the objects
thereof being to provide simple, inexpen-
sive and efficient apparatus of this character
which can be manipulated readily and which
does not require the use of any mechanical
15 means for agitating the milk.
A further object is to provide apparatus
of this character which has a large capacity
.and which does not require any special skill
to manipulate the same.
20 With the foregoing and other objects in.
view which will appear as the description
proceeds, the invention resides in the com-
bination and arrangement of parts and in
the details of construction hereinafter de-
25 scribed and claimed, it being understood
that changes in the precise embodiment of
the invention herein disclosed, can be made
within the scope of what is claimed, without
departing from the spirit of the invention.
30 In the accompanying drawings the pre-
ferred form of the invention has been
shown.
In said drawings:-
Figure 1 is a view partly in elevation and
35 partly in section of the apparatus.
Fig. 2 is a top plan view.
Fig. 3 is a section on line A-B Fig. 1.
Referring to the figures by characters of
reference 1 and 2 designate opposed tanks
40 formed of sheet metal or any other suitable
material and which are adapted to be*
packed with a suitable refrigerant such as
ice. These tanks are placed opposite each
other and the adjoining faces thereof are
45 formed with triangular corrugations 3.
The corrugations on the two tanks are dis-
posed in staggered relation so that the cor-
rugations on each tank will project between
the corrugations on the opposed tank a dis-
50 tance dependent upon the relative adjustment
of the two tanks. Upstanding from the ends
of each corrugation are retaining flanges 4
and extending from one of the tanks so as
to project below the lowermost corrugation
55 is a discharge trough 5 which may be in-dined downwardly toward one end and
project beyond the tanks. A guide plate 6
may be extended downwardly from the
lowermost corrugation so as to direct the
liquid into the trough 5. The two upper- 60
most corrugations on the tanks are adapted
to support a distributing plate 7 which is
bowed transversely as shown in Fig. 1 and
is provided with parallel gutters 8 formed
with apertures 9. End flanges 10 extend 65
upwardly from the distributing plate to
prevent overflow.
In using the apparatus, the two tanks 1
and 2 are filled with a suitable refrigerant,
such as ice, and are then adjusted toward 70
each other so as to form a tortuous passage
between the corrugated faces, said passage
being of a predetermined width. The milk
to be cooled and aerated is then poured onto
the distributing plate 7 and will flow down- 75
wardly in small streams through the open-
ings 9 and onto the corrugations thereunder.
These corrugations will cause the liquid thus.
fed to the apparatus to flow in a thin stream
downwardly along the corrugations, said 80
streams flowing from a corrugation on one
tank to the adjoining corrugation on the
opposed tank, thence back to the next lower
corrugation on the first tank. This oper-
ation is continued throughout the down- 85
ward course of the liquid and when it ulti-
mately flows into the trough 5 and issues
from the apparatus, it will be found to be
in a cool and thoroughly aerated condition.
What is claimed is:- 90
1. Apparatus of the class described in-
cluding opposed normally stationary cool-
ing tanks, said tanks having interfitting cor-
rugated faces' cooperating to form a tor-
tuous passage extending from the top to 95
the bottom of the apparatus, said tanks be-
ing slidable toward or from each other to
vary the transverse area of the passage, a
discharge trough carried by one of the tanks
and located between said tanks and above 100
the bottoms thereof to' receive liquid from
the tortuous passage, and an apertured dis-
tributing plate carried by one of the tanks
and normally extending over the passage.
2. Apparatus of the class described in- 105
cluding opposed normally stationary cool-
ing tanks, said. tanks having interfitting
corrugated faces coperating to form ator-
tuous passage extending from the top to
the bottom of the apparatus, said tanks 11J1,218,791.
