Year: 1885

page_text: JOHN PETRIE of Broomfield Rochdale in the County of Lancaster Machinist,
and FREDERICK WILLIAM PETRIE of 34 William Street Rochdale in the County of
Lancaster, Machinist do hereby declare the nature of our invention for MACHINERY
FOR CLEANSING "ESPARTO' AND OTHER GRASS AND FIBROUS MATERIAL USED IN
THE MANUFACTURE OF PAPER, to be as follows:-

Our Invention relates to the discharging of dirt, dust, or other foreign ingredients
contained in "fibrous material" used in the Manufacture of paper. The "Grass or
other fibrous material" we cause to pass through rollers by being spread upon an
ordinary travelling surface or feed brat, by which the said "material" is conveyed
to the aforenamed rollers--or the material may be supplied to the said rollers by a
Hopper shaped feed. On the delivery of the "Grass or other fibrous material
through the said rollers, it is struck by a revolving "Beater Fan on a portion of
the arms of which "Beater fan" we place cross bars armed with studs or teeth and
on the remainder of the arms of the said "Beater Fan" we affix flat plates, which
form the blades of the Fan. By the revolving of the "Beater fan
"the studs or
spikes strike the "Grass or other fibrous material" on its delivery from or through
the feed rollers so as to beat out the "Dirt and Dust and other foreign ingredients
contained therein, and the "flat plates" affixed to a portion of the arms of the said
"Beater Fan" further assist in depriving the "material" of the dirt and dust and
other foreign ingredients, contained therein, and also cause a blast of wind to be
made, assisting thereby the speedy delivery of the "material" being operated upon.
Underneath the "Beater Fan" we place a grid through which the "dirt and dust
er other foreign ingredients" discharged from the "material" by the aetion of the
said Beater Fan falls. Underneath this said Grid we place a second Grid which
we prefer to place in an inclined position, and with the interstices in a contrary
direction or at right angles to the interstices of the upper grid-The purpose of this
second grid is to catch or receive any fibrous material, which may in the course of
being operated upon, fall through the interstices of the upper grid. The dirt and
dust and other foreign ingredients discharged by the action of the "Beater Fan
from the "material" operated upon, will after passing through both grids fall into

page_text: the space or Chamber below the " second" Grid. We enclose the aforesaid
"Beater Fan" and "Rollers" and "Grids" in a casing or framework made of Iron
or other suitable material leaving an opening. through which the "material"
operated upon is delivered by the action of the "Beater and Fan." It will be
obvious that there may be dust discharged from the "material" operated upon too
light to fall through the grids placed underneath the "Beater Fan."
In order to prevent this dust from being discharged into the room in which the
machine may be placed we fix on the upper surface of the casing or framework,
suitable Tubes to which we attach an exhaust Fan in the well known ordinary
manner and by which the dust is drawn into and forced up a conducting tube to
be discharged at any desired point.

page_text: the grids No 10 and 11. will collect and be drawn by the action of the Fan N° 15
(shewn in dotted lines in Fig. 1 and in sectional drawing Figs. 2 & 3) and be thus
driven through the delivery pipe N° 16 to be discharged at any desired point.
N° 17. 17. Figs. 1 and 2 and No 18 Fig. 3 are moveable doors or covers giving
access to the chamber N° 12. for cleansing out or other purposes-N° 19 and 20.
Fig. 3 are the driving pulleys-the shaft No 21 of which carries the Beater Fan
No 5. On the shaft No 21- is placed a pulley N° 22 which drives the shaft N° 23.
through the pulley N° 24: On the shaft N° 21 is also placed the pulley N° 25
which drives the exhaust Fan N° 15 through the pulley N° 26 by means of the
belt N° 27..shewn in Fig. 3 and in dotted lines in Fig. 1. On the shaft N° 23 is
also placed
pulley N° 28. fig. 3. which through. the medium of the Belt N° 29. 29.
Fig. 1 & 3. drives the Top feed roller Nº 3. fig. 1. on which is fixed the pulley N° 30.
thus allowing the top feed roller N° 3 to rise or fall without changing the tension
of the Belt No. 29. 29. fig. 1. No 31 is another Pulley fixed on shaft N° 23.
driving the bottom roller No 2 fig. 1. by means of the Pulley N° 32 and Belt N° 33
in fig. 3. and shewn in dotted lines in fig. 1. . On the shaft of the bottom roller N° 2
is fixed wheel and pinions N° 34. 35 and 36. driving the feed or lattice Brat.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is:
1st The construction of a-Beater Fan armed with studs or teeth or with plates
or blades substantially as described.
2nd The combination of same with a dead plate armed with studs or teeth and
with one or more grids underneath and in combination with an exhaust Fan as
substantially described.
3rd The application of the said invention as described and set forth for the
purpose of cleansing "Esparto" and other grass and fibrous material used in the
manufacture of paper.
