the County of Lancaster, Flour Mill Engineers for an Invention of "IMPROVE-
MENTS IN CENTRIFUGAL DRESSING MACHINES FOR DRESSING FLOUR, GRAIN,
AND OTHER LIKE SUBSTANCES
"
PROVISIONAL SPECIFICATION left by the said Robert Lund and Thomas
Frederick Hind at the Office of the Commissioners of Patents on the
27th April 1883.

" IMPROVEMENTS IN CENTRIFUGAL DRESSING
MACHINES FOR DRESSING FLOUR, GRAIN, AND OTHER LIKE SUBSTANCES"
This invention of improvements in centrifugal dressing machines for dressing
flour, grain, and other like substances consists in mounting the rings or hoops upon
which the wire or silk gauze is stretched upon nibs or thimbles projecting from the
outer edge of the longitudinal rods or bars forming the body of the dressing cylinder
Eo that a space may be created. between the wire or silk gauze and the outer edges
of the longitudinal bars which heretofore have been in close proximity to the wire
or silk covering. Thus the flour or other material to be operated upon instead of
gathering or collecting in the angles or corners made by the contact of the wire or
silk gauze with the longitudinal bars will traverse freely through the space or
passage afforded between the outer edges of the bars and the inner side of the
wire or silk covering and thereby make the entire area of the gauze between the
rings or hoops available as dressing surface.

Patent Office on the 26th October 1883.
ROBERT LUND and THOMAS FREDERICK HIND of Preston in the County of
Lancaster Flour Mill Engineers IMPROVEMENTS IN CENTRIFUGAL DRESSING
MACHINES FOR DRESSING FLOUR GRAIN AND OTHER LIKE SUBSTANCES
This Invention of improvements in centrifugal dressing machines for dressing
flour, grain, and other like substances consists in mounting the rings or hoops,
upon which the wire or silk gauze is stretched, upon nibs or thimbles projecting
from the outer edge of the longitudinal rods or bars forming the body of the
dressing cylinder, so that a space may be created between the wire or silk gauze
and the outer edges of the longitudinal bars which heretofore have been in close
proximity to the wire or silk covering. Thus the flour or other material to be
operated upon, instead of gathering or collecting in the angles or corners made by
the contact of the wire or silk gauze with the longitudinal bars, which traverse
freely through the space or passage afforded between the outer edges of the bars
and the inner side of the wire or silk covering and thereby make the entire area
of the gauze between the rings or hoops available as dressing surface.
In the accompanying Drawings Fig. 1. illustrates in section the arrangement of
a longitudinal bar a in close proximity to the wire or silk covering 6 as heretofore
in use; Fig. 2. illustrates the main feature of our Invention, the bar a being placed
at a distance from the wire or silk b thereby leaving a space c through which the
flour or other material d may pass freely; and Fig. 3. shews in section the general
arrangement of the dressing cylinder and the position of the longitudinal bars a a
relatively to the wire or silk covering b.
Figs. 4. and 5. are views in cross and longitudinal section respectively in which
a is one of the longitudinal bars, e one of the rings or hoops upon which the wire
or silk gauze b is stretched, a nib or thimble interposed between the bar a and the
ring or hoop e, and g a fastening screw passing through the hoop e and thimble f
into the bar a.
Having now described the nature of the said invention and the mode of carrying
it into practical effect, we would have it understood that what we consider to be
novel and original and therefore claim as the Invention secured to us by the
herein before in part recited Letters Patent is as follows that is to say:
Providing a space or passage between the outer edges of the longitudinal bars
and the inner side of the gauze or covering of centrifugal dressing cylinders
substantially as described and shewn in the drawings?
In Witness whereof we the said Robert Lund and Thomas Frederick Hind have
hereunto set our hands and seals this twenty-fourth day of October in the
year of Our Lord one thousand eight hundred and eighty three.
