IMPROVEMENTS IN MACHINERY FOR ATED THE ADDSACH FOR PREPARING DOUGH, PASTE, AND LIKE ARTICLES
Year: 1858

page_text: LETTERS PATENT to Ebenezer Stevens, of Cambridge Road, in the County
of Middlesex, for the Invention of "IMPROVEMENTS IN MACHINERY FOR
ATED THE ADDS"
Sealed the 27th July 1858, and dated the 9th February 1858.
PROVISIONAL SPECIFICATION left by the said Ebenezer Stevens at the
Office of the Commissioners of Patents, with his Petition, on the 9th
February 1858.
I, EBENEZER STEVENS, of Cambridge Road, in the County of Middlesex, do
hereby declare the nature of the Invention for "IMPROVEMENTS IN MACHINERY
FOR PREPARING DOUGH, PASTE, AND LIKE ARTICLES," to be as follows:-
This Invention has for its object improvements in machinery for preparing
dough, paste, and like articles. For these purposes the upper part of the
vessel in which the materials are mixed is by preference of a rectangular and
the bottom of a semicircular form; through the bottom is an opening for the
passage of the dough, paste, or other articles, there being a slide by which
a portion can be cut off and the further passage of the dough stopped when
a sufficient quantity has descended into a tin or other receiver below. The
vessel is by preference made of cast iron, and the interior thereof coated with
enamel, and below the bottom there is formed a hollow space for receiving
warm water. In the interior of the mixing vessel is a stirrer, which consists
of a cranked axis, the two ends of which are arranged to be supported at the

page_text: ends of the mixing vessel in such manner that the cranked handle or other
means of driving the cranked axle may be readily attached and detached, and
allow of the cranked axis being conveniently removed out of the vessel. On
the cranked axis are applied one, two, or more blades, which are bent spirally
and in the rotation of the crank in the vessel; these blades, assisted by the
crank itself, stir the materials and mix them most intimately. The upper of
the mixing vessel is covered by tins, which form a cover when mixing, and
shapes for baking the dough in.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Ebenezer Stevens in the Great Seal Patent Office on the
9th August 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EBENEZER
STEVENS, of Cambridge Road, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of February, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Ebenezer Stevens, Her special licence that I, the said Ebenezer Stevens, my
executors, administrators, and assigns, or such others as I, the said Ebenezer
Stevens, 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 MACHINERY
FOR PREPARING DOUGH, PASTE, AND LIKE ARTICLES," upon the condition (amongst
others) that I, the said Ebenezer Stevens, 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
Isame 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 Ebenezer Stevens, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object improvements in machinery for preparing

page_text: preventing it from sliding lengthwise until, the catch is raised. In con-
structing machines of large size I prefer to employ the form of stirrer shown
at Figures 4; and in place of driving it directly by a crank handle, I arrange
an axis in suitable bearings, so as to pass horizontally along the side of the
vessel a, and on this axis I mount two pinions which gear with spur wheels
mounted on short axes at each end of the machine. These short axes are.
squared at one end, and fit into square holes in the ends of the cranked axis
of the stirrer. These short axes are each arranged in a manner similar to
the pin i, shewn in the Drawing, so that the toothed wheels may be slid out
of gear with the pinions and the stirrer removed from the vessel. I also in in
large machines arrange in a horizontal position a hollow metallic cylinder just
above the top of the vessel a. About one-half of the surface of this cylinder
is:formed of wire gauze, and it is arranged so that flour may be introduced
into the interior. There is a spur wheel mounted on the end of the cylinder,
and. it can at pleasure be thrown into gear with one of the large wheels from
which the stirrer receives motion, and when the cylinder is thus in gear.a
shower of flour is introduced into the vessel a at cach revolution of the
cylinder, and the flour being thus introduced a small quantity at a time is
rapidly kneaded in by the stirrer. To facilitate the taking out of the dough
in large machines, I prefer to arrange one side of the machine so that it may
be removed or lowered. When the quantity of dough is large it is more
readily removed at one side than by an opening in the bottom.
I would remark that some-forms of stirrers different from those shewn in
the Drawing may be used successfully, but the forms shewn are those which
I prefer.
In witness whereof, I, the said Ebenezer Stevens, have hereunto set my
hand and seal, this Seventh day of August, in the year of our Lord
One thousand eight hundred and fifty-eight.
Witness,
GEO. WOOLMER.
