Sealed the 3rd September 1867, and dated the 26th June 1867.
COMPLETE SPECIFICATION left by the said William Robert Lake at the
Office of the Commissioners of Patents, with his Petition and Declara-
tion, on the 26th June 1867, pursuant to the 9th Section of the Patent
Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the "International Patent Office," No. 8, Southampton
Buildings, Chancery Lane, in the County of Middlesex, Consulting Engineer,
send greeting..
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
CHURNS," and have petitioned Her Majesty to grant unto me, my executors,
administrators, and assigns, Her Royal Letters Patent for the same, and
have made solemn declaration that it has been communicated to me from
abroad by William Hookes Tambling, of Mazo Maine, Wisconsin, United
States of America.
NOW KNOW YE, that I, the said William Robert Lake, do hereby declare
that the following Complete Specification, under my hand and seal, fully

page_text: describes and ascertains the nature of the said Invention, and in what manner
the same is to be performed, in and by the following statement, reference
being had to the accompanying Sheet of Drawings making a part of this
Specification:-
The said improvements relate to the construction of a churn wherein the
butter is produced by the combined action of revolving wings formed of wire
gauze and a series of obliquely arranged arms and paddles attached to a hori-
zontal shaft. The said arnis and paddles are enclosed in a box of suitable
construction, and the gauze wings are arranged within another parallel box
provided with an aperture for the introduction of the milk, and communicating
with the other box through an opening covered with wire gauze.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a transverse section of my improved churn; Figure 2 is an end
elevation of the said churn; Figure 3 is a plan of the same; Figures 4 and 5
are detached portions.
A is the churn box, which is made with a curved bottom and supported
upon the legs B; this box is provided with a horizontal shaft D, which has
bearings in the end of the box A, and is provided with a series of arms E.
The said arms are provided on their outer ends with small paddles a, which
are arranged on the shaft D at a different inclination to that of the arms
themselves. The said arms are flat upon their sides, but are so turned when
secured to their shaft that each alternate arm throws the cream or milk in an
opposite direction. A cover K is secured upon the box A, which cover has
erected upon it a supplementary box C provided with a shaft F and an
elongated hopper or funnel H; the shaft F is furnished with wings of wire
gauze G; the inside of box C is cylindrical, as shown in Figure 1. There is an
opening in the bottom of the box C which leads into the churn box A, and this
opening is covered with wire gauze J, Figure 3. I, represents a driving wheel
which is provided with teeth, and is secured to the end of the box A by a short
shaft whereon it turns. The wheel I gears into a toothed wheel L on the end
of the shaft D, and serves to give motion to the same. M is a band which
passes around pulleys on the shafts D and F, and serves to communicate motion
to the shaft F. In using this churn the beaters are set in motion by the
revolving wheel I, the band M at the same time giving a rapid motion to the
.shaft F, with its wings G. The cream or milk after being properly tempered
is poured through the funnel or hopper H, and reaches the wings G in a thin
extended stream. The wings G operate upon it and break it up, and it then.
passes down through the bottom J to the lower box, where it is operated upon

page_text: by the arms and paddles forming the beaters upon the shaft D. By the
operation of these arms and wings the cream is so broken to pieces that the
butter is driven from it in an incredibly quick time.
Having thus fully described the said improvements, as communicated to me
by my foreign correspondent, and shown how the same may be conveniently
and advantageously carried into practice, I claim,-
First, the arrangement of the boxes A and C, the one provided with the
arms E and paddles a, and the other provided with gauze wire wings and
bottom, the two being constructed and used as and for the purpose specified.
Second, the arrangement of wire gauze either in the top or bottom portion
of the churn in the manner substantially as set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set
my hand and seal, this Twenty-sixth day of June, in the year of our
Lord One thousand eight hundred and sixty-seven.
WILLIAM ROBERT LAKE. (L.S.)
