ДОСИТь шасцІНОВ,
I, ELLIS CARR, of Drummond Road, Bermondsey, in the County of Surrey,
Biscuit Manufacturer, do hereby declare the naturo of this invention to be as
follows:-
My invention relates to those machines for manufacturing biscuits where the
dough is forced through dies.
The object of my invention is to construct a machine with continuous feed which
shall exert a greater forcing power on the dough than has hitherto been obtainable
in such machines.
To effect this in place of employing a roller or rollers with fixed teeth to act
upon the dough or a solid plunger as used. in machines on what is known as the
"Rout Press" principle I employ a revolving roller or rollers provided with a
number of blades or floats which are made movable in the sense they can be drawn
back so as to lie within and be even with the surface of the oyliuder or extended
beyond it like the floats or blades of a water wheel. Opposite to the descending
side of this roller is fixed a curved iron breast or casing and the blades on this sido
are made to project out from the roller and to fit against the interior of the breast.
The dough is placed on the top of tho roller and is carried down by the action of
the blades between the roller and the breast. The breast is provided with flanged
ends which extend sufficiently over the ends of the roller to prevent the escape of
the dough.
The breast or casing is also continued on the under side of the roller and there
amplified so as to form a chamber in which the compressed dough accumulates and
through openings in which, called dies it is forced out in streams of the required
form.
Before the blades commence to rise on the ascending side of the roller and while
they are still within the breast or casing they are withdrawn in turn by the action
of a cam or in other suitable way so that their edges are perfectly oven with the
surface of the roller. When thus withdrawn there is no projection or depression
of any kind on the surface of the roller consequently it is possible to make a close
end to the casing fitting the roller sufficiently tight to prevent the escape of
dough.
After passing the end of the casing the blades are by the action of a second cam
forced out again ready for further action on the dough.

Bisouit Machines.
I, ELLIS CARR of Drummond Road, Bermondsey, in the County of Surrey,
Biscuit Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
My invention relates to those machines for manufacturing biscuits where the
dough is forced through dies.
The object of my invention is to construct a machine with continuous feed which
shall exert a greater forcing power on the dough than has hitherto been obtainable
in such machines.
To effect this in place of employing a roller or rollers with fixed teeth to act
upon the dough or a solid plunger as used in machines on what is known as the
"Ront Press" principle I employ a revolving roller or rollers provided with a
number of blades or floats which are made movable in the sense that they can be
drawn back so as to lie within and be even with the surface of the cylinder or
extended beyond it like the floats or blades of a paddle wheel. Opposite to the
descending side of this roller is fixed a curved iron breast or casing and the blades
on this side are made to project out from the roller and to fit against the interior
of the breast. The dough is placed on the top of the roller and is carried down by
the action of the blades between the roller and the breast. The breast is provided
with flanged ends which extend sufficiently over the ends of the roller to prevent
the escape of the dough.
The breast or casing is also continued on the under side of the roller and there
amplified so as to form a chamber in which the compressed dough accumulates and
through openings in which, called dies it is forced out in streams of the required
form.
Before the blades commence to rise on the ascending side of the roller and whilo
they are still within the breast or casing they are withdrawn in turn by the action
of a cam or in other suitable way so that their edges are perfectly even with the
surface of the roller. When thus withdrawn there is no projection or depression
of any kind on the surface of the roller consequently it is possible to make a close
end to the casing fitting the roller sufficiently tight to prevent the escape of
dough.
After passing the end of the casing the blades are by the action of a second cam
forced out again ready for further action on the dough.
In the accompanying drawings Figure 1 is n vertical section of apparatus
constructed in the above manner. Figuro 2 is a view of one of the blades or
floats. Figure 3 is an end view of the same.
A is the roller, B the spaco into which the dough is fed to the machine, C the
space in which it accumulates before escaping through the die i, D the lower casing,
Fare the side plates fitting against the ends of the roller A and carrying bearings
for its shaft G. Any suitable mechanism may be employed for revolving this
shaft. E is the curved cast iron breast forming the back of the casing and
prolonged under the roller as far as the dough chamber C, it is formed with a
flange E at each end and these flanges are by bolts secured to the side
plates F.
abcdefg and h are the moveable blades or floats sliding in longitudinal slots
in the roller. a' b'c' de' f¹ g' and h¹ are projections at the ends of the blades or
floats carrying small rollers which work in grooves in the side casings shown by
the dotted lines, said grooves acting alternately as inside and outside cams to project
or withdraw the wings.

page_text: It will be seen that the bolts which secure the flanges E¹ to the side plates F.
pass through enlarged holes or slots in the flanges this allows of the breast being
adjusted perpendicularly or horizontally to regulate the distance between it and the
roller..
If the breast is to be raised thin paoking pieces of sheet metal may be interposed
between it and the table D to adjust its height or in place of these set screws may
be used. The position of the curved breast should be eo adjusted that each blade
as it comes round and fits against it should continue to fit against it until the next
succeeding blade fits against it. Afterwards a narrow gap or opening might
commence to form and slowly increase in width between the breast and the blade
so that some dough may pass back between it and the breast and put the dough
which is between it and the next succeeding blade under pressure before the blade
commences to be drawn back by the cam to allow it to pass the fixed portion of
the casing at o. This makes the pressure on the dough at the outlets more uniform
than it otherwise would be.
I is the stream of dough being forced through the diei; m is any suitable carrier
by which the dough is conveyed away for further treatinent and p is a sloping
shield over which the stream of dough passes to the carrier m.
The action is as follows:-
-
Dough being thrown in at B is caught by the extended blades or floats as they
come round in turn in the direction of the arrows and is carried down between the
roller A and the casing or curved breast E to the chamber C where it accumulates
under pressure and is forced out through the dio i.
Before arriving at the position the action of withdrawing each float is
commenced and completed before it passes the front of the casing D at o. At
this point the ends of the blades or floats are brought perfectly flush with the body
of the roller thereby allowing of close contact between the roller and the casing at o
to prevent the escape of the dough.
This point passed the action of the cam again forces the wing or flost out
from the body of the roller to its original position ready to act on the dough as
before.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved continuous dough feeding apparatus for biscuit machines
consisting of a hopper or casing, a revolving roller forming the upper portion of
one side of the hopper and a curved breast piece forming the opposite side, and of
blades or floats which are carried by the roller and can bo withdrawn within it when
carried past the point where the roller fits to the lower fixed portion of the hopper
and be protruded as they are carried round so that when they come opposite to the
curved breast they may fit closely to it, the curved breast being made of such a
length that one or more of the blades or floats is always closely fitting to it and
also having outlet dies or orifices at the lower part of the hopper through which
the dough is expressed substantially as described.
2. The breast made adjustable both horizontally aud perpendicularly substantially
as described.
3. The improved continuous dough feeding apparatus for biscuit machines
substantially us hereinbefore described and illustrated in the drawings annexed.
Dated this 21st day of November 1895.
