Improvements in Churns.
We, SIDNEY WILLIAM KEMISH, Metal Worker, and JOHN LYON, Fishmonger
both of 44, Paradise Street, Rotherhithe, in the County of London, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
This invention relates to improvements in churns, and has for its chief objects
to expedite the process of churning, facilitate the cleansing of the churn and
gathering the butter.
According to this invention we make the churn with a series of blades mounted
horizontally in the churn and in such a way that they can easily be removed for
the purpose of thoroughly cleansing the churn throughout and leaving the churn
clear to facilitate gathering the butter.
And in order that our said invention may be understood we will proceed to
describe the same with reference to the drawing accompanying this specification,
in which Fig. 1 shews a front elevation of a churn constructed according to this
invention; Fig. 2 a side elevation; Fig. 3 a plan; Fig. 4, plan with top or
lid turned back on its hinge, and Figs. 5 and 6 shew details hereinafter referred to.
The same letters denote the same parts in all the views.
a shews a cylindrical chamber the upper portion of which forms a lid turning
about the hinge c. d shews a catch or fastening for the lid b. A spindle e (sec
Fig. 4) provided with a number of blades f, is mounted within the chamber a in
such a manner that it may be readily withdrawn.
In order to effect this the ends of the spindle may be furnished with keys or
projections g as shewn in the end view of the spindle and blades at Fig. 5. These
keys fit in slots in short spindles and i at the ends of the chamber ab, and a small
sleeve may be slidden over this joint, as, shewn in the plan of one of these
joints at Fig. 6. The sleeves are secured, by means of thumb screws. The
blades have holes cut in them, preferably in the manner shown at Fig. 4, i..
so that the holes in the one blade shall come opposite to the solid part of the
next. These blades are rotated rapidly by means of the handle & and the toothed
wheel speed gear, consisting of two wheels m, n, and the two pinions o, p.
9 shews a vent and ra plug for closing same. s is a tap or outlet. t shews a
window.
The drawing represents a churn for domestic use, but it is obvious that large
churns may be made on the same principle, in which case a pulley may be used
instead of the handle k, so that the churns may be worked by steam or other
power; and thumb screws would be used for holding the cover down.
The action is as follows:-
The churn being charged with cream, the blades are rotated rapidly and the
cream is caught up by one blade when part passes through the openings and comes
against the solid portions of the next blade and the rest is dashed against the lid.

page_text: 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 what
we claim is:-
1. In churns, the employment of rotatable blades extending throughout the
length of the churn, or nearly so, such blades being perforated, preferably in
the manner described.
2. In churns, the employment of toothed wheel speed gear.
3. In churns, the employment of removable spindle and blades for the purposes
set forth.
