Improvements in Apparatus for the Manufacture of Butter.
We, NESTOR ROLLAND, of 50, Rue de Merode, Engineer, and HECTOR
FRANCOIS, of 36, Rue de Pascale, Gentleman, both in Brussels, in the Kingdom of
Belgium, do hereby declare the nature of this invention to be as follows:-
Our invention relates to apparatus for the manufacture of butter, and has for
object to provide improved means for causing purified air in the form of bubbles or
beads to pass through the milk for the manufacture of butter and thereby furnish
the necessary conditions to ensure purity of the product, and the required agitation
and bubbling for the complete separation of the butter held in suspension in the
milk.
The invention consists essentially in the employment of a suitable generator of an
air current, such, for example, as a fan or blower, a purifying vessel containing a
suitable material for effecting the filtration of the air and what I call a churn con-
nected with the blower and the air purifier by a pipe which delivers the air into a
perforated box placed in the bottom of the churn and made of two flanged parts
rivetted or bolted together the said air escaping from the box and then rising
through the milk to be treated.
The cylindrical sides of the perforated box are advantageously extended upwards
and connected to an outer cylinder so as to provide an annular chamber communi-
cating by means of perforations with the box below, and laterally with the liquid
within the upwardly extending sides so as to cause the air to act upon the milk in a
horizontal as well as in a vertical direction.
The air purifier is advantageously constructed of a cylindrical vessel provided
with a cover fastened by means of a hook or catch, so that it can be removed for
renewing the wadding serving to purify the air. The vessel is provided at each
of its sides with a nozzle, in front of which is arranged a sieve or grating allowing
of the passage of the air and preventing particles of wadding from entering the air
pipe.
The two nozzles are suitably joined to the two corresponding parts of the air

Improvements in Apparatus for the Manufacture of Butter.
We, NESTOR ROLLAND, of 50, Rue de Merode, Engineer, and HECTOR
FRANÇOIS, of 36, Rue de Pascale, Gentleman, both in Brussels, in the Kingdom of
Belgium, 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 :—
Our invention relates to apparatus for the manufacture of butter, and has for
object to provide improved means for causing purified air in a fine state of division
to pass through the milk for the manufacture of butter and thereby furnish the
necessary conditions to ensure purity of the product, and the required agitation and
bubbling for the complete separation of the butter held in suspension in the
milk

page_text: 15 minutes) in order to withdraw it from the churn, the pipe T is disconnected from
its sleeve t and lifted up and the box X F is withdrawn from the churn together
with the butter resting thereon within the rims. During the operation part of the
milk escapes through the perforations in the rini 2. When the butter is taken out
the box X F is taken to pieces for the purpose of cleaning it; the small quantity
of butter which may have formed between the two bottoms is easily removed and
the box is put back into the bottom of the churn after which the whole apparatus is
put into working order as before.
Instead of making the perforated box as hereinbefore described and illustrated in
Figures and 3 we sometimes extend the rim z upwards and provide it with
perforations X" as shewn in Figure 6, a second rim z¹ forming with the rim z an
annular chamber o, o which communicates (as indicated by the arrows) through
holes with the space between the two bottoms X and F.
N2 is an air outlet. X³, X' are openings for the discharge of the milk when,
after the manufacture of the butter, the false bottom or dish X FZ is withdrawn.
In this arrangement the air entering the box as previously stated through the
pipe T is distributed in the space formed between the two bottoms X F and part
of it escapes vertically through the perforations in the bottom X and part passes
through the holes X¹ into the annular space o, o to be horizontally projected into
the liquid through the perforations X" in the inner rim z. The result of this
modification in the interior arrangement is a considerable increase in the quantity
of butter produced in a given time as the butter particles, suspended in the milk.
and subjected simultaneously to the action of vertical and horizontal air jets, unite
and agglomerate very rapidly to form the mass of butter.
=
A practical result can also be obtained and the cost of the manufacture of the
apparatus be lessened by dispensing with the non-perforated bottom F Figure 1 and
having the annular perforated rim thereof turned downwards so as to rest upon
the bottom of the churn, the perforated bottom thus shaped being combined with
the other parts in the manner herein before described with reference to Figures 1
and 2.
The action on the milk contained in the churn may be considerably bastened or
facilitated by providing two or more perforated plates or bottoms supported
practically by the tube T. Preferably these plates or bottoms will be arranged at
about 6 inches from one another and in such a manner that 2 bottoms such as X =
Figure 1 will be arranged first one over the other with the specified distance between
them and over them a third bottom F X with annular chambers Z¹ Z' such as is
shewn in Figure 6, in which all the butter will be deposited and will remain as
owing to the difference of density the butter will be raised towards the top of the
churn.
The churn when worked is placed in an open vessel containing water brought to
a temperature corresponding to that which has to be communicated to the milk.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that we are
aware of Cole's Patent No. 13,197, of 21 August 1889 and make no claim to
anything therein described and claimed, but what we claim is :-
1. An apparatus for the manufacture of butter by means of an air current,
having an air forcing device, a removable pipe for conducting the air into the
bottom of the butter making vessel or churn, a receptacle mounted between the two
parts of the said pipe and containing wadding for the purification of the air, an
opening in the cover of the said receptacle for the outlet of the air, a perforated
plate having a perforated annular upward extension or rim and a non-perforated
annular downward extension or rim, substantially as hereinbefore described and for
the purpose specified.
2. The combination with the arrangement claimed in the preceding claiming
clause of a non-perforated plate having an upwardly extending annular rim corre-
sponding to the downward extension or rim of the perforated plate and provided or

page_text: not with bolts, substantially as hereinbefore described and illustrated in Figures 1,2
and 3 of the accompanying drawing.
3. The combination with the churn and removable pipe claimed in the first
claiming clause of a perforated plate or bottom baving a downwardly projecting rim
resting on the bottom of the churn, substantially as hereinbefore described.
4. An apparatus or churn for the production of butter by agitation by means of
air currents, consisting of a cylindrical vessel a pipe, provided at its lower end with
two plates, an annular extension or chamber above the said plates, the inner cylinder
of the said extension and the upper plate being perforated to cause the air to enter
the milk in both vertical and horizontal jets, the parts being united and combined
as shewn, and the said pipe being conuected at its onter end with an air forcing
device substantially as set forth.
5. A device for the agitation of cream consisting of an air forcing device, an air
filter, a cylindrical vessel or churn an air distributer comprising a pipe provided at
its lower end with two plates, an annular extension above the said plates the inner
cylinder of the said extension and the upper plate being perforated to cause both
vertical and horizontal jets, the parts being united as herein before described with
reference to Figures 2, 4, 5, 6 and 7 of the accompanying drawings.
6. In an apparatus or churn such as is herein described the arrangement of
several perforated plates and the combination of one of the latter with an inwardly
perforated annular cylinder such as is herein described for the purpose of hastening
or facilitating the production of the butter, substantially as hereinbefore described.
