I, JAMES EDWARD EDWARDS, of Windoor, Dominion of Canada, Upholsterer,
do hereby declare the nature of this invention to be as follows:-
This invention has reference to apparatus or means for separating cream from
milk, artificially; and has chiefly for its object to provide a simple mode of and
apparatus for effecting this purpose, so as to enable such apparatus to be sold
cheaply, and to be bought within such a price as will enable farmers and cow
keepers generally to obtain one.
According to this invention the separation
simple vessel by means of water which is introduced at the lower part of the
is effected in a stationary and
apparatus or vessel; and which distributes or defuses itself gradually through
the milk; the effect being that it acts upon the cream particles, and causes them
to separate out and rise to the surface.
When the milk has been so treated for a certain time, say about half an hour,
practically all the cream will have been separated; and then the milk and water
will be drawn off through a suitable tap below; and when this is removed, the
cream may be drawn off by the same tap, into a separate vessel.
In one form of apparatus, the vessel is cylindrical, and has near the bottom
an inclined floor, the lower part being just below the discharge outlet. And this
floor is further inclined upwards from the centre on each side. The water is
introduced through a funnel or tube on the out-side, leading to a point just
above the inclined floor; where it passes into the vessel; and between this point
and the outlet apperature or tube, is a detachable perforated tube or piece,
through the perforations of which the water to be mixed with the milk issues.
The upper part of the vessel has a cover in the form of a funnel with a grid
or strainer at its apex. Normally this acts as a cover; but by reversing it, and
lacing it over the mouth of the vessel, it acts as a funnel and strainer.
trainer is also placed over the mouth of the water inlet, which is preferably
lush with the upper part of the body.
A
In the body of the vessel glazed windows are introduced at suitable heights,
o show the level of the cream and conditions of the discharge.
The apparatus may be made of tin plate, or any other suitable material.

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:―
This invention has reference to apparatus or means for separating cream from
milk, artificially; and has chiefly for its object to provide a simple mode of and
apparatus for effecting this purpose, so as to enable such apparatus to be sold
cheaply and to be bought within such a price as will enable farmers and cow-
keepers generally to obtain one.
It is known that water can be added to milk for the purpose of raising cream;
but until now, this process of bringing together water and milk is done in an
unsuitable manner, so that the separation of the cream takes place very slowly.
By the present invention the process of raising cream, will be effected more
quickly than hitherto. The new process consists in principle, that the water or
other suitable fluid is introduced into the vessel containing milk, by or at the
lower part of the vessel, or inversely the milk is introduced into the vessel of
water also, by or at the bottom. By this special method of introduction, the
milk mixes immediately with water, and in consequence of the upward current
every particle of cream, which is higher than the mixture of milk and water,
rises and comes quickly together at the top. The quantity of the water must be
about half of the quantity of milk. This process of raising cream needs about 40
minutes for new milk, and about 50 to 60 minutes for older milk.
Means for carrying out the present invention are represented in the annexed
drawings in vertical section. The vessel a is cylindrical, and has near the
bottom an inclined floor b, the lower part being just below the discharge outlet i,
and this floor is further inclined upwards from the centre on each side. The
water is introduced through a funnel or tube g on the outside, leading to a point
just above the inclined floor; where it passes into the vessel; and between this
point and the outlet aperture or tube, is a detachable perforated tube or piece h,
through the perforations of which the water to be mixed with the milk issues.
Thus the distributing pipe is immediately above the inclined bottom b.
Instead of pouring first the milk into the vessel a, and afterwards introducing
the water through the funnel g, the water can be put into the vessel, and then
by means of the funnel and the distributing pipe h the milk will flow in from
below.
By this the same operation is effected.
In order to observe the state of the operation of raising the cream, a gauge
glass f, is fixed to the vessel.
By means of the tap i the skimmed milk or mixture of milk and water can be
first drawn off, and after this the cream may be allowed to flow into a separate
vessel.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. The method of separating cream from milk by means of the addition of
water or other suitable fluid, consisting in causing the water or other fluid
to enter the milk from below or inversely causing the milk to enter the water
from below,

page_text: 2. A vessel for separating cream by the process described in claim 1, composed
of a vessel a, provided with a gauge glass, a lateral funnel g which is fixed to
the distributing pipe h, close above the inclined hollow bottom of vessel a
