IMPROVE- MENTS IN SILK REELS OR APPARATUS FOR DRESSING FLOUR, MIDDLINGS, WHEAT-MEAL, GROUND OR CRUSHED GRAIN OR SEEDS, BRAN, OR POLLARD."
Year: 1881

page_text: LETTERS PATENT to Charles William Maconchy, of Templeogue Flour Mills,
Templeogue, in the County of Dublin, Ireland, for an Invention of " IMPROVE-
MENTS IN SILK REELS OR APPARATUS FOR DRESSING FLOUR, MIDDLINGS,
WHEAT-MEAL, GROUND OR CRUSHED GRAIN OR SEEDS, BRAN, OR POLLARD."
PROVISIONAL SPECIFICATION left by the said Charles William Maconchy
at the Office of the Commissioners of Patents on the 20th August 1881.
CHARLES WILLIAM MACONCHY, of Templeogue Flour Mills, Templeogue, in the
County of Dublin, Ireland. "IMPROVEMENTS IN SILK REELS OR APPARATUS FOR
DRESSING FLOUR, MIDDLINGS, WHEAT-MEAL, GROUND OR CRUSHED GRAIN OR
SEEDS, BRAN, OR POLLARD."
Heretofore in bolting machines it has not been found practicable to prevent the
coarser materials being (by the draught in the bolting chest) blown back on to the
flour, and thus making it dirty and lowering its value in the market. Now
according to my Invention to obviate this inconvenience and enable clean flour to
be produced without such waste, there is provided a circular flexible stop joint or
division between every two compartments of the bolting chest to prevent inter-
communication and consequent draught, such as above referred to.
The flexible stop joint or division is formed of a ring of flexible material attached
at its outer circumference to a division formed in the bolting chest. The inner
circumference of this flexible ring is turned back and sewn over an india rubber
ring so as to strain the flexible ring or stop tight.
A collar attached to the reel revolves against the flexible ring, which ring is
partly kept close against it by the elasticity of the india rubber ring, thus forming
a flexible stop joint between any two compartments of the bolting machine chest,
where heretofore a space has been left through which the draught has carried
the light particles of bran and pollard, and thus mixed them with the flour.
The collar of wood or other suitable material is attached to the reel in such a
position as to press against the flexible ring and force it out of a right line with
its side or face, thus causing pressure of the flexible ring against the side of the
collar more or less, according to its position on the reel with relation to the
partition or division where the outer edge or circumference of flexible ring is fixed
and thus becoming self acting and self adjusting. The application of the flexible
material is such that the flour acts as a lubricant between it and the collar.

CHARLES WILLIAM MACONCHY, of Templeogue Flour Mills, Templeogue, in the
County of Dublin, Ireland. IMPROVEMENTS IN SILK REELS OR APPARATUS FOR
DRESSING FLOUR, MIDDLINGS, WHEAT-MEAL, GROUND OR CRUSHED GRAIN OR
SEEDS, BRAN, OR POLLARD,"
Heretofore in bolting machines it has not been found practicable to prevent
the coarser materials being (by the draught in the bolting chest) blown back
'on to the flour, and thus making it dirty and lowering its value in the market.
Now according to my Invention to obviate this inconvenience and enable
clean flour to be produced without such waste, there is provided a circular
flexible stop joint or division between every two compartments of the bolting
chest to prevent intercommunication and consequent draught, such as above
referred to.
The flexible stop joint or division is formed of a ring of flexible material
attached at its outer circumference to a division formed in the bolting chest.
The inner circumference of this flexible ring is turned back and sewn over an india
rubber ring só as to strain the flexible ring or stop tight.
A collar attached to the reel revolves against the flexible ring, which ring is
partly kept close against it by the elasticity of the india rubber ring, thus
forming a flexible stop joint between any two compartments of the bolting
machine chest, where heretofore a space has been left through which the draught
has carried the light particles of bran and pollard and thus mixed them with the
flour.
"
In the accompanying Sheet of Drawings Fig. 1 is a longitudinal sectional
elevation of a bolting chest containing a silk reel provided with circular flexible
stop joints or divisions according to this Invention between every two compartments
of the bolting chest. One joint only is shewn, but it is intended to apply such
joints to as many divisions as may be considered necessary.
Fig. 2 is a sectional plan of the same.
Fig. 3 is a transverse section in line A, B, Fig. 1.
Fig. 4 is an elevation of the ring of flexible material.
Fig. 5 is a section to a larger scale of the stop joint taken in the longitudinal
axis of Fig. 1.
a is a silk reel carried on the inclined shaft b and rotating within the bolting
chest c.
This chest is divided into compartments by partitions or divisions of
which one only, marked d, is shewn in the Drawings. This partition or division
which is set perpendicularly to the axis of the reel, has an aperture for the
passage of the said reel and of the collar e (of wood or other suitable material)
fixed to it.
To effect a tight closure between the partition and the collar a flexible stop joint
is employed formed of a ring f of flexible material attached at its outer circum-
ference g to the division or partition d. The inner circumference of this flexible
ring is turned back and sewn over an india rubber ring h (Fig. 5) so as to strain
the flexible ring tight. The collar e is attached to the reel in such a position as
to press against the flexible ring and force it out of a right line with its side or
face (Fig. 5), thus causing pressure of the flexible ring against the side of the collar
more or less, according to its position on the reel with relation to the partition or
division where the outer edge or circumference of the flexible ring is fixed,

flexible material is such that the flour acts as a lubricant between it and the
collar.
Having thus described the nature of the said Invention and the manner in which
it is to be performed, I would have it understood that what I consider to be
novel and original and therefore claim as secured to me under the Letters Patent
herein before in part recited is,-
1. In silk reels or apparatus for dressing flour, middlings, wheat-meal, ground or
crushed grain or seeds, bran, or pollard, the application and use between adjacent
compartments of the bolting chest of flexible stop joints or divisions, all
substantially as and for the purposes hereinabove described.
2. In apparatus of the kind referred to in the preceding claim, the arrangement
of parts constituting a flexible stop, joint, or division, substantially as described
and shewn.
In witness whereof, I, the said Charles William Maconchy, have hereunto
set my hand and seal, this Thirty-first day of January, in the year of
our Lord One thousand eight hundred and eighty two.
