An Improved Machine for Making Butter.
I, HUGH DONALD FITZPATRICK, of 70 Wellington Street, Glasgow, Registered
Patent Agent, 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 relates to a butter making machine which produces butter in a
compact condition by simply swinging the cream, which is enclosed in a vessel, to
and fro without using axle-trees with stirrers on them or similar arrangements
inside the vessel. In this way the production of butter is accelerated and it is
produced in a pure state at the one operation i.e. it requires no further washing or
kneading. At the same time the greatest cleanliness is obtained. As there are no
complicated arrangements in the vessel and as the cream does not come in contact
with inside walls, as in the usual centrifugal or swinging apparatuses, the cleaning
of the whole machine is made extremely easy.
And in order that my said invention may be properly understood I have hereunto
appended two explanatory sheets of drawings whereon:-
Fig. 1 is a side view of the machine.
Fig. 2 is a plan view.
Fig. 3 is a front view, partly in section.
Fig. 4 is a back view partly drawn in section.
Figs. 5 and 6 show a method of fitting the butter machine (Figs. 1-4) with two
or more milk vessels.
Figs. 7 & 8 show a modified form of the machine.
The novelty in this new machine consists in using a vessel A for the cream which
is made of glass or of similar material so as to be easily cleaned. The vessel A. is so
arranged within the machine that a very fast forward and backward motion may be
given to it in order to produce the conglomeration of the butter particles, without
using any stirring apparatus and without any part of the contents of the vessel
being removed during the formation of the butter.
The drawing Fig. 1 shows, by way of example, a butter-machine which is driven
by hand. The parts of the machine are mounted on a base plate B which latter
may be fastened by clamps or screws on the table. The cream vessel A is held
between claws b, c, which are fastened to the carrier C.
The claw rests in an eye or bearing e in the upright arm of the carrier C,
whilst the claw c is movable and held in position by an adjusting screw / which
passes through the eye d of the arm g.
The claw c clutches and is guided in its movement by the rib i of the carrier C.
The carrier C is, at the bottom, formed dove-tail-wise and slides in the guide D
which latter is fitted on the base plate B.
The rod E connects the carrier C with the fly-wheel F, so that, as the wheel
revolves, the connecting rod causes the carrier to have a reciprocating motion.
The distance of travel of the carrier can be regulated by moving the head k of
the rod E, which is capable of being moved in the slot of the fly-wheel, either
further from or nearer to the axis m of the wheel.
The grooved wheel n is also fitted on the axle m and is connected with the driving
wheel o by means of a strap or a cord p so that by turning the driving wheel o the
wheels n and fare also caused to revolve and actuate the connecting rod so as to
produce a forward and backward motion of the carrier C with its cream vessel A.
The vessel A is first about half filled with cream, then firmly closed and properly

page_text: fixed between the claws b and c. The driving wheel o is now turned and the
machine put in motion and kept going until the large butter particles are to be
seen swimming in the milk and the sides of the cream vessel appear bright.
When the butter is thus properly separated the vessel A is taken out of the
machine by screwing back the claw c.
The butter is taken out of the butter milk in the usual way i.e. by straining the
mixture.
From the foregoing it will be seen that the separation of the fat in milk or cream
is, by this machine, produced by simply shaking the contents of the cream vessel
forward and backward.
Not only is a larger per-centage of butter produced in this way but the
buttermilk is also better, having a medical value in so far as it is entirely free
from fat.
As the whole process is performed in a vessel A (which can be easily cleaned and
which contains no mechanical stirring apparatus) the machine as already mentioned
can be easily cleaned, because the butter making part of the machine consists
merely of the said vessel A which is reciprocated by the machinery.
The modifications illustrated at Figs. 5 and 6 show how the efficiency of the
machine can be doubled or trebled &c. This is done by making the carrier C so
that it can receive two, four, or more, cream vessels which are held in place in the
same way as at Figs. 1-4 i.e. between claws b and c which are fixed to the
carrier C. These Figs. 5 and 6 show an arrangement for four vessels A.
In the arrangement shown in Figs. 7 and 8 instead of using a carrier C, the
cream vessels are held in bearers or arms M which are fixed on the axle N. In
the outer end of each arm is carried a cream vessel which is retained in position in
the same manner as before.
The axle N which may be made with any number of arms or bearers so as to
carry any desired number of cream vessels is swung back and forward turning on
the axle N as a centre by the motion of the connecting rod E and crank E' so as
to separate the butter from the milk in the same manner as before described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
==
A butter making machine having one or more milk or cream holding vessels (A)
made preferably of glass or of other suitable material which can be easily cleaned,
said vessels being fitted in a machine which gives them a very quick forward and
backward motion, either rectilinear or swinging, and thereby produces the
separation and conglomeration of the fat particles without necessitating the removal
of the contents of the vessels, substantially as hereinbefore set forth with reference
to the drawings annexed.
