IMPROVEMENTS IN OR APPLICABLE TO CENTRIFUGAL FLOUR DRESSING MACHINES
Year: 1879

page_text: LETTERS PATENT to Joseph Bedford, of Leeds, in the County of York, Corn
Mill Engineer, for the Invention of "IMPROVEMENTS IN OR APPLICABLE TO
CENTRIFUGAL FLOUR DRESSING MACHINES."
PROVISIONAL SPECIFICATION left by the said Joseph Bedford at the Office
of the Commissioners of Patents on the 23rd January 1879.
JOSEPH BEDFORD, of Leeds, in the County of York, Corn Mill Engineer.
" IMPROVEMENTS IN OR APPLICABLE TO CENTRIFUGAL FLOUR DRESSING
MACHINES."
This Invention relates to apparatus to be employed in centrifugal flour dressing
machines or in immediate connexion therewith, for the purpose of breaking up the
material fed thereto, which is necessary when the material has passed through rollers
and is introduced to the centrifugal machine in flakes or cohesive masses. For this
purpose I introduce a machine which is composed of a wrought or cast iron rim
attached to the head-plate of the centrifugal machine, from which rim project strips
forming an inner cage or cylinder, the ends of the strips being bent at right angles
and connected to the central shaft of the machine. This cage is covered with wire-
gauze or perforated sheet metal or other suitable material.
A set of beaters work inside the cage and drive the roller-ground middlings
against the side and through the perforations therein, thus breaking up the flakes
so as to prepare the material for the centrifugal machine.

"IMPROVEMENTS
IN OR APPLICABLE TO CENTRIFUGAL FLOUR DRESSING
MACHINES."
This Invention relates to apparatus to be employed in centrifugal flour dressing
machines, or in immediate connexion therewith, for the purpose of breaking-up the
material fed thereto, which is necessary when the material has passed through
rollers, and is introduced to the centrifugal machine in flakes or cohesive masses.
For this purpose I introduce a machine which is composed of a wrought or cast
iron rim attached to the head plate of the centrifugal machine, from which rim
project strips forming an inner cage or cylinder, the ends of the strips being bent
at right angles and connected to the central shaft of the machine. This cage is
covered with wire gauze or perforated sheet metal, or other suitable material. A
set of beaters work inside the cage and drive the roller ground middlings against
the sides and through the perforations therein, thus breaking up the flakes so as to
prepare the material for the centrifugal machine. For the purpose of improving
the action of the beaters I form them of wood or metal channelled or corrugated.
In order that my Invention may be more fully understood, I herein give reference
to the accompanying Sheet of Drawings.
Fig. 1 is a side elevation in section of a centrifugal flour dressing machine,
with my apparatus, which I call a "detacheur" applied thereto; Fig. 2 is an end
view of the said "detacheur."
"
"
"
A is the ordinary framework of a centrifugal flour dressing machine, B being the
cylinder usually covered with silk gauze ; C is the shaft which carries the beaters E
and F, which are made of wood or other suitable material, and grooved or corru-
gated, as shewn in detail, Fig. 3. Within the cylinder B is the detacheur Gt,
which is formed of wrought iron ribs a, fastened to angle iron stays, bolted to the
head plate of the large cylinder. The detacheur" cylinder is covered with
wire gauze H at the periphery, and partially covered at the end opening to the
cylinder B, as shewn in thick dotted lines in Fig. 1, and also in Fig. 2. The material
is first supplied to the cylinder G, and being broken up by the beaters is forced
through the gauze, by which it is broken up or reduced to a comparatively fine
condition before being acted upon by the beaters F.
Having described the nature of my Invention, and shewn by Drawings how the
same may be performed or carried into practice, I would have it understood that I
do not confine myself to the precise dotails of construction, as the same may be
varied, but what I claim as my Invention, and consider to be new is,-
The employment of a preparatory machine placed within or in immediate con-
nexion with the ordinary centrifugal machine, substantially as and for the purpose
herein shown and described.
In witness whereof, I, the said Joseph Bedford, have hereunto set my hand and
seal, this Seventeenth day of July, in the year of our Lord One thousand eight
hundred and seventy-nine.
JOSEPH BEDFORD. (LS)
