Alsop at the Office of the, Commissioners of Patents, with
their Petition, on the 3rd February 1853.
(Void by reason of notice to proceed not having been given within
the time prescribed by the Act.)
We, JOHN CROWTHER, of Huddersfield, Contractor, & JOSEPH ALSOP,
of Huddersfield, Baker, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN BAKING BREAD" to be as follows:-
There are to be two or more cylinders of cast iron mounted on a
frame in positions to be hereafter described; these cylinders will
be open at both ends, and will be supported and work on three
friction pullies at each end; these pullies will be situated with regard
to their peripheries (which will be in contact with the peripheries
of each cylinder at or near their respective ends) in three points
of a semicircle having a little larger radius than the cylinders; one
pulley being fixed at each end of the horizontal diameter; and one
at the bottom of the vertical diameter: A circular groove will be
cast to form a path in the said cylinders for the aforesaid friction
pullies to traverse; the edges of these pullies being rounded off
for that purpose. One end of each the aforesaid cylinders will be
fitted with a toothed rack, surrounding their circumference, fitted in

page_text: a pedestal attached to the framing. Between the said circular
racks will be two spur wheels of equal radii, one being in contact
with the rack of one cylinder, and the other in contact with that of
the other cylinder, as also in contact or gearing into each other; on
the axle of one of these wheels will be fixed a handle or pully to
receive the moving power. The cylinders aforesaid will be a short
distance apart, and one of these cylinders with its friction pulley
supports will rest in a sliding frame, so that the distance between
the said cylinders may be lessened or enlarged at pleasure. These
cylinders will be heated by gas within them, or grates (fed with
coal or coke), fastened to bracket supports, attached to the main
frame, supporting central rods, laying in the axis of each cylinder,
and extending through to the chimney back. These grates so
fixed in the interior of each cylinder to be of such..dimensions.
as to allow sufficient space under each grate for the necessary
supply of air, and the deposit of ashes into a circular shaped ash
pan suspended from the grates in the lower part of the interior
of the said cylinders, and nearly filling such parts. Sliding on
the central rods which support the grates shall be fixed metal
discs or doors of nearly the same diameter as the interior of
the aforesaid cylinders. At the opposite end of the said cylinders
to which these doors are fixed will be a metal pipe supported by
brackets, on the main frame. This metal pipe will have a circular
flanged end of such diameter as to fit the interior of the cylinders.
The end of this metal pipe will be inserted in a brick or stone flue.
leading to chimney shaft, paralell with the outside surface of the
lower of these cylinders before described, and underneath it will be.
fixed a roller gearing by a toothed wheel with the circular rack of
the cylinder before specified. Opposite to this roller and at a short
distance and in the same plane will be a similar roller; these rollers
will be connected together by a number of small chains, or metallic:
web, or strong cloth. In close contact with the surface of one of
these cylinders, the upper one will be fixed a bevel edged bar of
steel, to be called the cleaner; this cleaner will have a sliding motion
along the face of the aforesaid cylinder. To effect this one end of:

page_text: the said cleaner will be attached to an eccentric surrounding the
cylinder, as hereafter described. A feeding trough will be fixed
nearly in contact with the surface of the upper cylinder; this trough
at one end will be supported on an axis (supported by brackets
fixed to the framing), the other end being supported by a chain
passing over a pully so as to adjust the said trough to any required
inclination. This trough will be fitted with a valve divided by
stops into the required widths of the bread the trough will be
connected with, and receive its supply from the mixing tub by
means of a pipe fitted with a stop valve. Resting on brackets
supported by frames, and paralell with and near to the roller last
herein described, will be fixed a small inclined table, supporting a
knife or chopper on levers, whose ends are alternately lifted and
depressed by pins fixed on the roller, the number of these pins
varying according to the required use of the cakes. Now, the fires
being lighted as aforesaid, the batter or paste is to be let into the
feeding trough, the valve of this trough opened to the required
thickness, and the trough raised to the inclination required, the
batter or paste will then fall upon and pass over the cylinders on
to the web covering the rollers, and pass under the knife, falling
from thence, when cut, into a basket prepared to receive it bread.
