Year: 1854

page_text: Sealed the 22nd May 1855, and dated the 15th December 1854.
PROVISIONAL SPECIFICATION left by the said Arthur Lyon at the
Office of the Commissioners of Patents, with his Petition, on the
15th December 1854.
I, ARTHUR LYON, of Windmill Street, Finsbury, in the County of Middlesex,
Sausage Machine Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINES FOR REDUCING OR MINCING MEAT AND
OTHER SOLID EDIBLE SUBSTANCES" to be as follows:-
The Invention consists in forming the top and bottom of the case of such
machines, generally known as "sausage machines," hollow, or in fitting them
with water-tight cases, provided with suitable inlet and outlet passages, or
with one passage only, to serve both purposes, for the purpose of containing
hot water, or for steam to be passed into and through them, to keep the meat
and other substances warm while going through the machine. I form the
barrel or drum of white metal, and cast on one end a wheel or shield to keep.
the substances from the axis on which the barrel revolves, while on the opposite

page_text: end I cast three or more portions or threads of a screw, in order to force the
substances from the machine after having been cut. Instead of providing
the upper part of the box or case with a hinge at one side and a hasp at that
opposite to it, I make it with two hasps, so that it can be readily removed
when required for the purpose of cleaning or otherwise. I fix the machine on
a convenient stand by means of a thumb-screw inserted in the bottom thereof,
which passes through a slot in the top of the stand, and is secured by turning
the head of the screw at an angle to the slot. ⚫
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Arthur Lyon in the Great Seal Patent Office on the
15th June 1855.
TO
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ARTHUR
LYON, of Windmill Street, Finsbury; in the County of Middlesex, Sausage
Machine Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of December, in the year of our Lord
One thousand eight hundred and fifty-four, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Arthur Lyon, Her special licence that I, the said Arthur Lyon, my
executors, administrators, and assigns, or such others as I, the said Arthur
Lyon, 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 "IMPROVEMENTS IN MACHINES FOR
REDUCING OR MINCING MEAT AND OTHER SOLID EDIBLE SUBSTANCES," upon the con-
dition (amongst others) that I, the said Arthur Lyon, by an instrument in
writing under 'my hand and seal; 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 immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Arthur Lyon, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following

page_text: statement thereof, reference being had to the Drawings hereunto annexed
(that is to say):
My Invention consists in forming the top and bottom of the case of such
machines, generally known as "sausage machines," hollow, or in fitting them
with water-tight cases, provided with suitable inlet and outlet passages, or with
one passage only, to serve both purposes, for the purpose of containing hot
water, or for steam to be passed into and through them, to keep the meat and
other substances warm while going through the machine. I form the barrel or
drum of white metal, and cast on one end a wheel or shield, to keep the
substances from the axis on which the barrel revolves, while on the opposite
end I cast three or more portions or threads of a screw, in order to force the
substances from the machine after having been cut. Instead of providing
the upper part of the box or case with a hinge at one side and a hasp at that
opposite to it, I make it with two hasps, so that it can be readily removed when
required for the purpose of cleaning or otherwise. I fix the machine on a
convenient stand by means of thumb-screws inserted in the bottom thereof,
which pass through slots in the top of the stand, and are secured by turning the
heads of the screws at an angle to the slots.
In the Drawings hereunto annexed I have shewn one of these machines
constructed according to my Invention. Figure 1 represents an external
elevation, and Figure 2 a section of the same.
-A, A, is a stand, formed of metal, and cast in a piece with the sole plate. B,
which is of considerable thickness, in order to give steadiness to the machine
when being worked; C, C', is a box or case, which is made in two halves. The
part C is secured to the frame or stand A by means of the screws a, a, which
are passed through slots in the upper portion thereof, and the heads then turned
at an angle to prevent their slipping out of the slots; D, D¹, are water-tight
cases, which are fitted into and secured to the boxes C, C¹, and contain hot
water, steam, or other heating medium for keeping the contents of the machine
warm; E, E', are short pipes, which communicate with the interior of the
cases, and are for introducing and withdrawing the heating liquid into and
from them; they are closed by the screws b, b. F, F, are hasps, which are
hinged to the upper case C¹, the lower ends thereof being slotted out to fit
over the staples G, G, upon the lower case C. H (Figures 2 and 3) is the
barrel or drum, fitted upon the spindle I, and turning in sockets between
the cases C, C'. This barrel is studded spirally with teeth J, J, which work
between the stationary knives K. L is a disc or shield upon the drum, for
preventing the meat or other substances while being cut from falling on to the
axis of the drum; and M, M, are portions of a screw upon the opposite end

page_text: of the drum, for forcing out the substances when cut; N is a feed hopper;
and O, a spout into which the cut substances are forced from the case;
P is a handle for giving motion to the barrel.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that what I claim as my Im-
provements in Machines for reducing or mincing Meat and other solid Edible
Substances is,―
First, the fitting the interior of such machines with water-tight cases, for
the purpose of containing hot water, steam, or other heating medium to keep the
meat and other substances warm while being cut, and while passing through
the machine.
Second, I claim the making the outer cases of such machines of two parts
fixed together, and also to the stand, in the manner herein-before described.
Third, I claim the fitting the drum or barrel of sausage or mincing machines
with a disc or shield at one end, and also with portions of a screw at the
opposite end, as herein-before described.
In witness whereof, I, the said Arthur Lyon, have hereunto set my
hand and seal, this Twelfth day of June, One thousand eight hundred
and fifty-five.
ARTHUR LYON. (L.B.)
