PROVISIONAL SPECIFICATION.
Improvements in or connected with the Manufacture of Butter.
I, THOMAS BRADFORD, of 140, High Holborn, in the County of. London,
Dairy, Engineer, do hereby declare the nature of this invention to be as follows:-
In the churning of cream into butter, the labour of churning is proportionately
increased as the cream gradually thickens, owing to the increasing resistance offered
by the thickening and greater consistency of the cream, which impedes and
neutralizes the action of those parts of the churn which are operative upon the
cream, some considerable portion of which latter is liable to adhere in a plaster-like
manner to both the operative and other parts of the churn and to be left inefficiently
churned.
The object of this invention is to obviate such disadvantages, in “box" churns,
in which the churning vessel or cream container is stationary and the operative
parts of the churn have motion imparted to them, (examples of which are described
in the Specifications accompanying my applications for Patents Nos. 18768-93,
18825-93, 22784-93 and 24011-93,) by combining with the churn suitable!means
of conveying and delivering either water or milk either skimmed or unskimmed or
other suitable lubricant-liquid to and upon the parts of the churn which it is desirable
to keep free from any lodgment of cream, both in respect of those parts: which are
operative in effecting the churning process, as well also if required, in respect of
the internal surface of the churn generally; with the object of, as it were,
lubricating such parts and avoiding liability of the adherence of the cream thereto,
while also lessening the resistance offered to the operation of the apparatus; which
will enable the granulation into butter to be more speedily effected and with a
more uniform and less expenditure of power.
According to one modification, I apply to such a churn a suitably shaped
container of the lubricant made with an adjustable outlet or outlets suitable in
size to the capacity of the churn, and in position to the formation thereof, so as to
enable any required specific quantity of the lubricant used being, delivered or
injected upon any required part of the interior or of the operative parts of the
churu..

I, THOMAS BRADFORD, of 140, High Holborn, in the County of London,

manner the same is to be performed, to be particularly described and ascertained

The object of this invention is to obviate such disadvantages in "box" churns, in
which the churning vessel or cream container is stationary and the operative parts of
the churn have motion imparted to them, (examples of which are described in the
Specifications of my Patents Nos. 18768-93, and 18825-93, and of those accom-
panying my applications for Patents Nos. 22784-93 and 24011-93) by combining
with the churn, suitable means of conveying and delivering either water, or milk either
skimmed or unskimmed, or other suitable lubricant-liquid to and upon the parts of the
churn which it is desirable to keep free from any lodgment of cream, both in respect of
those parts which are operative in effecting the churning process, as well also, if

of, as it were, lubricating such parts and avoiding liability of the adherence of the

and with a more uniforin and less expenditure of power..
On the accompanying drawings:-
Fig. 1. represents in sectional elevation a box churn of the nature aforesaid,
showing the same as having applied thereto or combined with the lid A. thereof,
a lubricant container B, adapted to supply the water, milk or other lubricant-liquid
in regulated quantity to or upon the churning fingers, roller or drum C, of the
churn, operating within the churning vessel upon the contained cream.
Figs. 2 and 3, represent enlarged views, in sectional elevation and plan respectively,
of a modified construction of churn lid similarly adapted as aforesaid.
As represented, the lubricant container B, is fitted to the lid A, by a metallic
plug 6, let into a hole a', made in the lid. The plug is formed with an outlet
hole b, the stream of lubricant exuding from which may be regulated, as desired,
by a plug . The plug, is continued above the bottom of the container, as at b*,
for a sufficient distance to form a well 6, for the settlement of any sediment, and to
cause the lubricant to be drawn off from the clear liquid.
The lubricant-container B, may be made of any other suitable shape than that
represented, and of any size suitable to the capacity of the churn, and may be
applied to the sides or ends of the churn preferably at the upper part thereof and
if required with a lateral inlet so as to enable the lubricant to be delivered upon
any required part of the interior of the churn, and its outlet may be regulated in
any other convenient manner than that represented.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
1. In combination, a box-churn and means of delivering lubricant liquid upon the
interior parts thereof for the purpose aforesaid.
2. In combination, a box-churn and the means hereinbefore described of
delivering lubricant liquid upon the interior parts thereof for the purpose aforesaid.
3. The hereinbefore described means of delivering lubricant liquid upon the
interior parts of box churns for the purpose aforesaid.
