& Co., Non-conducting Composition Manufacturers, of Gray Street,
Commercial Road, in the County of Middlesex, for the Invention
of "AN IMPROVED MIXING MACHINE.”
PROVISIONAL SPECIFICATION left by the said Charles Simon at the
Office of the Commissioners of Patents, with his Petition, on the
28th June 1873.
I, CHARLES SIMON, Foreman to Messieurs F. Leroy & Co., Non-
conducting Composition Manufacturers, of Gray Street, Commercial
Road, in the County of Middlesex, do hereby declare the nature of the
said Invention for "AN IMPROVED MIXING MACHINE," to be as follows, that.

homogeneous mass for the manufacture of what is known as F. Leroy &
Co.'s non-conducting composition, but also applicable for mixing the
materials used by paper makers and brick makers, for mixing mortar and
for other mixing purposes.
This machine is constructed of a circular iron pan placed on four
friction rollers and revolving on a centre or pivot. The pan is driven
by means of a pinion on a vertical shaft gearing into a cog wheel on the
bottom of the pan.

shaft forming a continuation of the first described horizontal shaft extends
from the centre to the outside of the pan. These horizontal shafts
work in plummer blocks and are provided at their outer ends with fast
and loose pulleys and are driven in opposite directions by straps from the
steam engine. The said shafts are provided with a number of blades
or beaters made flat at the back and tapering towards the front and end,
and so shaped that they shall not take up the hair and fibre, but
effectually mix up the materials and form the said composition, mortar,
cement, or other material, as the case may be, by working the same in
opposite directions.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Simon in the Great Seal Patent Office on
the 27th December 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
SIMON, Foreman to Messieurs F. Leroy, & Co., Non-conducting Com-
position Manufacturers, of Gray Street, Commercial Road, in the County
of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of June, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Charles Simon, Her special licence that I, the
said Charles Simon, my executors, administrators, and assigns, or such,

page_text: others as I, the said Charles Simon, my executors, administrators,
and assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "AN IMPROVED MIXING MACHINE,"
upon the condition (amongst others) that I, the said Charles Simon,
my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Charles Simon, do hereby declare
the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the Drawing hereto
annexed and to the figures and letters marked thereon; that is to
say-
:-
This Invention consists in an improved construction of machine for
mixing tough fibrous substances such as hair, flax, and other fibres,
with liquid clay and other non-conducting ingredients so as to form a
homogeneous mass for the manufacture of what is known as F. Leroy
& Co.'s non-conducting composition, but also applicable for mixing
the materials used by brickmakers for mixing mortar and for other
mixing purposes.
This machine is constructed of a circular iron pan placed on four
friction rollers and revolving on a centre or pivot. The pan is driven
by means of a pinion on a vertical shaft gearing into a cog wheel on the
bottom of the pan. The vertical shaft is worked by means of a worm
and pinion attached to a horizontal shaft placed above the top of the pan
and extending from the outside to the centre thereof. Another shaft
forming a continuation of the first described horizontal shaft extends
from the centre to the outside of the pan. These horizontal shafts,
work in plummer blocks and are provided at their outer ends with fast
and loose pullies and are driven in opposite directions by straps from the
steam engine. The said shafts are provided with a number of blades

page_text: or beaters made flat at the back, front, and sides, but tapering towards
the end, and so shaped that they shall not take up the hair and fibre
but effectually mix up the materials and form the said composition,
mortar, cement, or other like material, as the case may be, by working
the same in opposite directions.
Having thus described the nature of my said Invention I will now
proceed to more particularly describe the same by reference to the
accompanying Drawing, in which Figure 1 is an elevation, the pan
being shewn partly in section, of my improved mixing machine, and
Figure 2, side elevation of one of the beaters. a, a, is the circular iron
pan; b, b, the friction rollers; c, the centre or pivot revolving in the
footstep d; e is the cog wheel on the bottom of the pan a; fis the
pinion gearing into and driving the cog wheel e; g, vertical shaft of the
pinion f; h, footstep or bearing of the shaft g; i is the pinion on the
upper end of the vertical shaft g driven by the worm or endless screw j
on the horizontal shaft / placed above the pan; k³ is the shaft forming
a continuation of the shaft k; 1, 1, plummer blocks or bearings of the
shafts k, k¹; m, m³, n, n¹, fast and loose pullies of the shafts k, k², re-
spectively to allow of the shafts being driven in opposite directions by
straps from the engine, as shewn by the arrows; A, A, is a wooden
framing supporting the whole machine; o, o, o, are the blades or
beaters fixed on the horizontal shafts k, k¹. One of these blades or
beaters is shewn in detached side elevation at Figure 2.
In this improved construction of mixing machine the materials to be
mixed are placed in the pan a and the machine being set in motion the
pan revolves slowly in the direction of the arrow x, and the shafts k, k²,
with the beaters o, o, revolve rapidly and in opposite directions as herein-
before described. By this arrangement and the peculiar shape of the
beaters, the materials are throughly and rapidly mixed and kneaded into
a homogeneous mass.
Having thus described my said Invention and the best means I am
acquainted with for carrying the same into effect, what I claim is,-
Firstly. The general arrangement and construction of mixing machine
in which a revolving pan is combined with two horizontal shafts pro-
vided with blades or beaters and revolving in opposite directions, sub-
stantially as herein-before described and represented in the accom-
panying Drawing.

page_text: Secondly. The peculiar shape of the blades or beaters as herein-before
described and shewn in the accompanying Drawing.
In witness whereof, I, the said Charles Simon, have hereto set
my hand and seal, this Twenty-fourth day of December, in
the year of our Lord One thousand eight hundred and seventy-
three.
