IMPROVEMENTS IN APPARATUS FOR COOLING MILK AND SEPARATING CREAM THEREFROM
Year: 1884

page_text: I NICOLAS MOES Machinist of Kedingen an der Attert in the Grand Duchy of
Luxemburgh do hereby declare the nature of my Invention for IMPROVEMENTS IN
APPARATUS FOR COOLING MILK AND SEPARATING CREAM THEREFROM and in what
manner the same is to be performed, to be particularly described and ascertainēd
in and by the following statement:-
The object of my invention is to effect improvements in apparatus for cooling
milk and separating the cream therefrom.
And in order that my said invention may be clearly understood reference is
hereby made to the accompanying drawings in which similar letters of reference
indicate corresponding parts in the several figures.
Fig. 1 is a side view of the apparatus, Fig. 2 is a section of the same, and Fig.
is a plan or top view.
The water for cooling the milk enters the distributing pipe A. by means of the
pipe a, from whence it ascends to the spaces C. by opening one or more of the cocks
B. which allows the water to pass by the passages b.
The cool water from below causes the warm water above it to flow into and
down the pipe D. whereby it is drained away by means of the pipe E.-The height
of the water in C. C. C. surrounding the pans F, is regulated by means of the upper
portion of the pipe D. which is telescopic; the greater the quantity of milk in F,
the higher is the level of the water in C, and surrounding F.
The pans F. are moveable and are formed as shewn in Figs. 2 and 6, The
bottom is formed narrower than the top, and is also made to slope towards the exit
at H, This emission pipe is formed with an elbow, as shown in Fig. 2. There is
an india rubber collar at m, n, forming a fluid tight joint. A disc rubber valve is
placed over the end of each of the pipes H, which are held by the springs L. J. as
shewn in Figs. 1 and 2. By moving the spring J. and valve aside, as shewn at J',
Fig. 1, the orifice is uncovered, and the milk or cream, can be drawn off from F,-
K is a spring for holding the pan F in its place.
The perforated tube Ŏ has a telescopic tube fitted as shewn, for regulating the
flow of the milk. The lower part of the tube O. has a flange which makes a tight
joint when resting on the bottom of F. But when it is raised the milk flows

page_text: through the perforations at w. Above this flange is the strainer o¹, consisting of
small perforations or gauze wire, through which the milk percolates when the flange
is down.
Before pouring the milk which is to be skimmed into the pans F. F. the tube O
is held up for a short time to allow the lower portion of the milk (usually containing
impurities) to flow out through the holes at w. After this has been done the
tube is lowered, and the milk percolates through o¹ as before mentioned, the
milk being thereby screened, and the cream retained in the pans F. F.
When all the skimmed milk has been drawn off, the tube O is removed, and the
cream is allowed to flow through H into suitable vessels for use.
Figs. 4 and 5 are separate views of the tube O. and sliding tube Q.
The skimming may also be effected from the surface by means of the skimming
utensil R (Figs. 8 and 9) which is caused to rest against the walls of the pans F,
by means of the rubber handles. r, and by bringing the sieve into a horizontal
position, the cream is skimmed, the milk flowing off as the cream is caught.
Fig. 7, P, represents a scraper which is used to collect the remaining cream,
attached to the walls of the pans F.
The pans F are readily removable for cleansing purposes, and when so removed,
the tanks C, C, C, can be also cleansed, the necessary water being allowed to flow
through the passage at m, n, Fig. 2.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what I
claim is
1. The method of cooling milk and separating the cream therefrom, in the manner
substantially as herein before described and shewn on the drawings.
2. The manufacture and use of the improved apparatus for cooling milk and
separating the cream therefrom, substantially as herein before described and shewn
on the drawings.
3. The general arrangement and combination of parts together respectively
forming my improvements in the construction of apparatus for cooling milk and
separating the cream therefrom, substantially as hereinbefore described and shewn
on the drawings.
