Improvements in Butter Working Apparatus.
I THOMAS BRADFORD of the Crescent Iron Works Salford in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention consists principally of an improved construction of butter working
roller having circumferential or annular flutes or conical projections on the surface
instead of longitudinal conical flutes or projections as heretofore.
These circumferential flutes on the roller will be made so that they may roll the
newly churned butter into corresponding conical flutes, or ridges and furrows, and
by preference are made square or flat at the apex and also at the base.
The square apex is designed especially for leaving a smooth angular channel for
running off the moisture thus expressed from the butter more freely.
And secondly I propose to carry out more effectually the improvements patented
by me No. 22784 of 1893 in which I provide for a lateral or end wise movement of
the roller on its axis, when quiescent, so that by such lateral movement of the roller
either to the right or to the left I can bring the square or flat apex of the annular
projections on the said roller into contact with the square apex of the flutes of the
butter, so that I may then by a forward or a backward movement of the roller upon
the square apex of the flutes on the butter, transform such apex into the channel,
and vice versa, the channel into the apex, and by this means I am enabled to expel
more thoroughly and more quickly all moisture such as butter milk after churning,
or moisture after brining or salting, and with less injury both to the texture and the
color of the butter than by any other method now in use.
I
A further improvement which I propose to effect by this peculiar shape of roller
is that, in consequence of its thus leaving each apex of the butter solid and thereby
bringing the apex of the circumferential flutes on the roller into line with the apex
of the flutes on the butter the roller may impinge upon the butter sufficiently, and
so that when the roller is turned it will curl up the butter into a roll, which roll
will by changing its position (lengthways instead of cross ways) on the table be
ready for re-rolling out again into flutes until all moisture is thereby expelled.
A further improvement consists in the combination with such or similar roller of
a table upon which the butter is placed while being worked as described by me
in the Specification of the Patent (No. 22784 of 1893) above referred to which
table I secure by a hinge or centre pins at one end in the framework which supports
it so that the table itself can be tilted upon the framework and supported by a
suitable leg or sliding bar, notching into suitable corresponding holes or slots so
that the table can be tilted up to any degree of angle or altitude at its other end,
and by this means the moisture being expelled from the butter by the said roller
can run down the steep slope with great rapidity.
Dated this 15th day of September 1894.

I THOMAS BRADFORD of the Crescent Iron Works, Salford, in the County of
Lancaster, Engineer, 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 consists principally of an improved construction of butter working
roller having circumferential or annular flutes or conical projections on the surface
instead of similar longitudinal flutes or projections as heretofore; and my invention
will be readily understood on reference to the accompanying drawings.
Fig. 1 is a longitudinal section of a butter working roller and table made
according to my invention.
Figs. 2 and 3 shew transverse sections of the table with the roller in two positions
hereafter more particularly referred to.
a is the table a¹ (Figs. 1 and 2) part of its supporting frame, b is the fluted
butter working roller carried (see Fig. 1) by the movable side brackets & supporting
its axle ; c (Figs. 2 and 3) is the butter under treatment.
The circumferential flutes on the roller b will be made so that they may roll the
newly churned butter into correspondingly inclined flutes, or ridges and furrows
(see Fig. 2), and by preference are made square or flat at the apex 6+ and also at the
base, as shewn on Figs. 2 and 3.
The square apex is designed especially for leaving a smooth angular channel
in the butter for running off the moisture thus expressed from the butter more
freely.
A second object attained by this construction of roller b is to carry out more
effectually the improvements patented by me (No. 22784 of 1893) in which I
provide for a lateral or endwise movement of the roller on its axis, when quiescent,
so that by such lateral movement of the roller b either to the right or to the left
(say from left to right as shewn by Figs. 2 and 3) I can bring the square or flat
apex of the annular projections + on the said roller into contact with the square
apex of the flutes of the butter c (see Fig. 3) so that I may then by a forward or
a backward movement of the roller upon the square apex of the flutes on the
butter c, transform such apex into the channel, and vice versa, the channel into the
apex, and by this means I am enabled to expel more thoroughly and more quickly
all moisture, such as butter-milk, after churning, or moisture after brining or salting,
and with less injury both to the texture and the color of the butter than by any
other method now in use.
с
A further improvement which is effected by this peculiar shape of roller is that, in
consequence of its thus leaving each apex of the butter solid and thereby bringing
the apex of the circumferential flutes on the roller into line with the apex
of the flutes on the butter, the roller may impinge upon the butter sufficiently, and
so that when the roller when pushed forward, for example by the hand rail in the
direction of the arrow &, is turned in the direction of the arrow y it will curl up the
butter into a roll, which roll will by changing its position (lengthways instead of
cross ways) on the table be ready for re-rolling out again into flutes until all
moisture is thereby expelled.
A further improvement consists in the combination with such or similar roller as
above described of a table a upon which the butter is placed while being worked as
described by me in the Specification of the Patent (No. 22784 of 1893) above
referred to, which table I secure by a hinge or centre pins a+ (Fig. 1) at one end
in the framework a' which supports it, so that the table a itself can be tilted upon
the framework as shown and supported by a suitable leg or sliding bar, notching if
necessary into suitable corresponding holes or slots so that the table can be tilted

page_text: up to any degree of angle or altitude at its other end, and by this means the moisture
being expelled from the butter by the said roller can run down the steep slope with
great rapidity.
Fig. 1 on the drawings shews a rectangular sliding bar d which can be pushed
nearer to the centre or pivot at as it is required to raise the end of the table a
higher. Or a cylindrical bar may be used as shown dotted at d' on the same fig.
When not in use the said bar d or d¹ may be put out of the way and supported
by brackets a fixed on the frame a¹.
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 working roller having circumferential or annular flutes or conical
projections (preferably flattened at the apex and the base) mounted upon an axle
capable of lengthwise and rotary motion substantially as and for the purposes
hereinbefore set forth.
