Year: 1861

page_text: LETTERS PATENT to Ebenezer Stevens, of Nos. 5, 6, and 7, Cambridge.
Road, Bethnal Green, for the Invention of "IMPROVEMENTS IN MACHINERY
POR PREPARING DOUGH AND PASTE."
Sealed the 2nd August 1861, in pursuance of an Order of the Lord Chancellor,
PROVISIONAL SPECIFICATION left by the said Ebenezer Stevens at
the Office of the Commissioners of Patents, with his Petition, on the
15th January 1861.
I, EBENEZER STEVENS, of Nos. 5, 6, and 7, Cambridge Road, Bethnal
Green, do hereby declare the nature of the Invention for "IMPROVEMENTS
IN MACHINERY FOR PREPARING DOUGH AND PASTE," to be as follows:-
This Invention has for its object improvements in machinery for pre-
paring dough and paste. For these purposes I apply to the mixing machinery
formerly described in the Specification of my Patent dated 9th February 1858,
apparatus and machinery to supply flour thereto, such apparatus and ma-
chinery consisting of a hopper or supply vessel, in the lower part of which is a
rotating axis having oblique blades thereon, so that when the axis is rotated
and the slide or slides at the bottom of the hopper or feeding vessel are more
or less open, the flour will descend into the mixing machine and become incor-
porated with the dough or paste therein.
The hopper or feeding vessel is covered, and when desired to have a larger

page_text: supply of flour than the hopper or vessel will hold, then a shoot connected to
a bin or other holder of flour above the hopper or feed vessel is connected with
the cover of the hopper, so that any desired quantity of flour may be allowed
to descend into the hopper or feed vessel, and such supply may be shut off or
regulated by a slide. The axis within the hopper or feeding vessel has a cog
wheel thereon gearing into a cog wheel on the axis of the mixing machine,
provision being made to put these wheels out of gear, when a further
supply of flour from the hopper or feeding vessel into the mixing machine
is no longer required. In order that the flour supplied from the hopper
or feeding vessel may be applied in such manner as to "dust" over the dough
or paste in the mixing machine, there is a moveable inclined board, on to
which the flour is received as it descends from the hopper or feeding vessel;
to this board a quick vibratory motion is communicated, by which the flour is
dusted or distributed over the dough or paste below. When the flour is
desired to descend freely to the mixing machinery the board is retained in a
stationary position.
SPECIFICATION filed in pursuance of the conditions of the Letters Patent,
and of an Order of the Lord Chancellor, by the said Ebenezer Stevens
in the Great Seal Patent Office on the 15th August 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EBENEZER
STEVENS, of Nos. 5, 6, and 7, Cambridge Road, Bethnal Green, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of January, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth 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 AND PASTE," upon the condition (amongst
others) that I, the said Ebenezer Stevens, my executors or administrators, by

page_text: 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 In-
vention, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within. seven 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
dough and paste. For these purposes I apply to the mixing machinery for-
merly described in the Specification of my Patent, dated 9th February 1858,
apparatus and machinery to supply flour thereto, such apparatus and machinery
consisting of a hopper or supply vessel, in the lower part of which is a rotating.
axis having oblique blades thereon, so that when the axis is rotated, and the
slide or slides at the bottom of the hopper or feeding vessel are more or less
open, the flour will descend into the mixing machine and become incorporated
with the dough or paste therein.
The hopper or feeding vessel is covered, and when desired to have a larger
supply of flour than the hopper or vessel will hold, then a shoot connected
to a bin or other holder of flour above the hopper or feed vessel is con-
nected with the cover of the hopper, so that any desired quantity of flour may
be allowed to descend into the hopper or feed vessel, and such supply may be
shut off or regulated by a slide. The axis within the hopper or feeding vessel
has a cog wheel thereon gearing into a cog wheel on the axis of the mixing
machine, provision being made to put these wheels out of gear when a further
supply of flour from the hopper or feeding vessel into the mixing machine is no
longer required. In order that the flour supplied from the hopper or feeding
vessel may be applied in such manner as to "dust" over the dough or paste
in the mixing machine, there is a moveable inclined board, on to which the
flour is received as it descends from the hopper or feeding vessel; to this board
a quick vibratory motion is communicated, by which the flour is dusted or dis-
tributed over the dough or paste below. When the flour is desired to
descend freely to the mixing machinery the board is retained in a stationary
position.
And in order that my Invention may be most fully understood and readily
carried into effect, I will proceed to describe the Drawings hereunto

page_text: Figure 1, Sheet 1, shows a mixing machine, such as is described in the
Specification of the Patent above referred to, combined with apparatus for
supplying flour to it; Figure 2, Sheet 2, shows separately a front view of the
apparatus for supplying flour; Figures 3 and 4 show end views, and Figures 5
and 6, longitudinal and transverse sections of the same.
The mixing machine being similar to the one described in the above-men-
tioned Specification, it will be unnecessary to give any description of it here.
I will therefore only describe the machinery for supplying flour to it..
The machinery is composed of a hopper a, in the lower part of which is an
axis b, having on it oblique blades c, c; at the bottom of the hopper are open-
ings fitted with slides d, d; these slides can be opened more or less by handles
d', d. At one end of the axis b is a toothed wheel c, which can be caused to
gear with the toothed wheelf on the axis of the mixing machine (see Sheet 1);
when the slides are opened and the axis b is caused to rotate, the flour in the
hopper will descend into the mixing machine, but when it is desired to stop
tho supply of flour to the mixing machine, the slides d may be closed, and the
toothed wheel e moved along its axis by the handle e', so that it shall be out of
gear with the toothed wheel f. When it is desired to fill the hopper with
flour, the lid of the hopper can be turned up on the hinges g, g; the upper part
of the front of the hopper can also be turned down on the hinges h, h, to permit
a workman more readily to empty a sack of flour into the hopper; the lid of
the hopper has also a hole through it which is fitted with a slide i; the hopper
is fed through this opening when the flour is contained in a bin or other holder
above the hopper, a canvass or other shoot conducting the flour from the bin
through the opening. On the opposite end of the axis 6 to that which carries
the wheel e is fixed a toothed wheel k; this wheel drives a small pinion / on
the axis of which is an excentric m, the rod m² of which is formed with a fork,
which embraces a pin n' on an arm n; this arm is fixed to an axis o, on which
is fixed the board p; the board p will thus have a quick vibratory motion
communicated to it when the axis bis rotated; the flour as it falls from the
hopper descends on to this board and is by it dusted or distributed over the
dough or paste in the mixing machine below. When it is desired that
the flour shall fall direct into the mixing machine, the fork on the excentric
rod m' is lifted off the pin n' the board p will then drop into a vertical
position, so that the flour coming from the hopper will not fall on to it. The
instrument marked A on Sheet 1 is for lifting the dough or paste out of the

page_text: mixing machine; when the dough or paste is sufficiently mixed, the stirrer is
removed from the mixing machine, and the instrument A is inserted in its
place, and when caused to turn round it scoops up the dough or paste.
In witness whereof, I, the said Ebenezer Stevens, have hereunto set my
hand and seal, this Fourteenth day of August, in the year of our Lord
One thousand eight hundred and sixty-one.
E. STEVENS. (L.S.)
