A MACHINE FOR CHOPPING MEAT FOR SAUSAGES, AND OTHER LIKE PURPOSES
Year: 1811

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
DAVIS, of Royal Oak Yard, Bermondsey Street, in the Borough of Southwark,
and County of Surry, Engineer, send greeting.
WHEREAS His most Excellent: Majesty King George the Third did, by
His Letters Patent under the Great Seal of the. United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Seventh day of August,
in the fifty-first year of His reign, give and grant unto me, the said William
Davis, my exors, adññiors, and assigns, His especial licence, full power, sole
privilege and authority, that I, the said William Davis, my exors, adiñors, and
assigns, during the term of years therein mentioned, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, my Invention of "A MACHINE FOR CHOPPING MEAT FOR
SAUSAGES, AND OTHER LIKE PURPOSES;" in which said Letters Patent there is
contained a proviso, obliging me, the said William Davis, by an instrument in
writing under my hand and seal, to. cause a particular description of the nature
of my said Invention, and in what manner the same is to be performed, to be
enrolled in His Majesty's High Court of Chancery within two calendar months
after the date of the said recited Letters Patent, as in and by. the same, relation
being thereunto had, may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Davis, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are fully described and ascer-

page_text: tained in and by the Drawings hereunto annexed, and the following references
thereto and description thereof, that is to say:-
Fig. 1 is an elevation or side view of the machine; Fig. 2 is an end view of
the same, for the power of two men, each drawn upon a scale of two inches to
a is a head, to
a foot. The same letters in each view refer to the same parts.
which the knives or choppers bare fixed by the shanks c, and keeps and bolts d;
and e, f, are screws to raise or fall the knives or choppers, as circumstances
may require; g, a thickness of wood in the trough or box h, on which the
meat or fat, &c. is to be laid to be chopped. The trough or box h is to be
moved alternately from one end to the other on the friction roller by the
ratchet wheel n and spindle o and pinion i working in the endless rack k; the
pinion is kept in gear by a piece of metal, as represented by the dotted lines
in the bearing of the spindle o; next, the pinion i works in an oblong groove
or mortice, as represented by Fig. 3, so that the pinion i may work in the top
and bottom parts of the rack k alternately. p is a spindle or axle, on which is
hung the fly wheel 7 and pinion r; on the ends of the spindle p are the
On one
cranks r, a, s, connecting rods from the cranks r, a, to the head a.
of the cranks r, a, is the connecting rod t, which is jointed to the lever y, and
gives motion to the ratchet wheel n by means of a catch working in the teeth of
the said ratched wheel, as represented by the dotted lines marked catch 2. The
dotted lines marked catch 1 is a catch to prevent the ratchet wheel n from
going back when the machine is in motion. u, slides for the head a to work
.in upwards and downwards alternatively; v, wheels to give the fly wheel q a
motion of about two hundred and fifty revolutions per minute, and con-
sequently the number of strokes of the choppers will be the same, and the
trough h, with the wood g, at intervals when the choppers are not in contact
with the wood g. a, the framework; v, e, handles or cranks, whose centres
are w, by which the machine is to be worked. Fig. 4, the manner which
the edges of the knives or choppers come in contact with the wood g, in order
that that which is cut or chopped with the knives or choppers on one side of
the head a may be cut crossways with the knives or choppers on the other
side of the head a; the slides w may, if thought preferable, have a joint, as
represented by the dotted lines at z, and fastened at top by a pin, key, or any
other well-known contrivance.
I think it necessary to mention that this machine is drawn in a good
proportion to be made of iron, but it may be made of various kinds of
materials if the several parts are made of a size according to their strength,
which a competent workman will be a judge of. This machine can be
put together various ways. For example, the centre of the cranks may

page_text: be placed above or below the knives, and the framework made according,
and may be driven by one or more cranks, which is easy to be conceived
by a good mechanic; but the way described by the Drawings thereunto
annexed I generally give the preference to, for its strength and durability.
This machine may likewise be worked with riggers in place of cog wheels,
or with a greater or less number of wheels or riggers, provided that the
calculation is so that the choppers move a good chopping speed. The length
of stroke of the choppers may be more or less, according to circumstances.
These machines may be made larger or smaller, according to the given power
that is to work the machine, and may be worked by men, horse, steam, wind,
or water, or any other proper power; it will be necessary for a clearer to pass
through betwixt the knives, which may be made of any of the harder metals,
and fastened to the frame or slides to prevent the knives from being choked or
filled up betwixt them.
In witness whereof, I, the said William Davis, have hereunto set our
bands and seal, the Second day of October, in the year of our Lord
One thoucond night hundred a
