Improvements relating to the Suction Tubes or Trunks of Cotton
Opening Machines.
We, Joux Duxx, of 20 Rigby Street, Preston, in the County of Lancaster,
Cardmaster, JOSEPH WILLIAM PATESON of 42, Lower Bank Road, Fulwood, in
the same town, Cashier, WILLIAM RILEY, of 169, Newhall Lane, in the same
town, Cotton Mill Manager, and JOHN WILDING, of 47, Maitland Street, in the
same town, Mechanical Engineer, do hereby declare the nature of this invention to
be as follows:-
i.
This invention has for its object to increase the means for cleaning the cotton
during its passage through the suction tube or trunk of a cotton opening machine
or porcupine.' Such tubes or trunks are usually arranged horizontally and are
made (in cross section) with an arched or rounded top and a flat bottom the
bottom consisting of a hinged lid somewhat above which is a grate or grid formed
of a number of flat metal mrs placed side by side edgewise up with parallel spaces
between them through which the dirt as it leaves the passing cotton escapes on to
the lid below whence it is removed at intervals. According to our invention we
provide the interior of the upper arched part of the tube and in some cases its two
perpendicular sides with short projecting teeth pins or fingers which the flying
cotton as it is drawn through the tube strikes against becoming thereby addi-
tionally agitated and the dust and dirt in the cotton being more effectually
liberated or shaken out. The teeth pins or fingers may be of various forms to suit
circumstances that is to say the class of cotton being operated upon and the power of
the air current within the tube. We arrange the Hat metal bars forming the grate
or grid below longitudinally that is to say in the same direction as the length of
the tube instead of transversely thereof as has heretofore been the practice and
place them closer together than has been usual so that the cotton may the more
readily pass along the face of the grate or grid and the fibre of the cotton be pre-
vented from passing down through the said grate or grid.

Improvements relating to the Suction Tubes or Trunks of Cotton
Opening Machines.
We, Joux Desx, of 20 Rigby Street, Preston, in the County of Lancaster,
Cardmaster, JOSEPH WILLIAM PATESON, of 42 Lower Bank Road, Fulwood, in
the same town, Cashier, WILLIAM RILEY, of 169, Newhall Lane, in the saine
town, Cotton Mill Manager, and JOHN WILDING, of 47 Maitland Street. in the
same town. Mechanical Engineer, do hereby declare the nature of this invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
This invention has for its object to increase the means for cleaning the cotton
during its passage through the suction tube or trunk which conducts the cotton
from the opening machine or "porenpine" to the beater. Such tubes or trunks
are usually arranged horizontally and are made (in cross section) with an arched
or rounded top and a flat bottom the bottom consisting of a hinged lid somewhat
above which is a grate or grid formed of a number of flat metal bars placed side
by side edgewise up with parallel spaces between them through which the dirt as it
leaves the passing cotton escapes on to the lid below whence it is removed at

page_text: intervals. According to our invention we provide the interior of the upper or arched
part of the tube and in some cases the perpendicular part of its sides above the
grate or grid with short projecting teeth pins or fingers which the flying
cotton as it is drawn or sucked through the tube strikes against becoming thereby
additionally agitated and the dust and dirt in the cotton being more effectually
liberated or shaken out. The teeth pins or fingers may be of various forms to suit
circumstances that is to say the class of cotton being operated upon and the
power of the air current within the said tube.
In the accompanying drawings,
Fig. 1 is a cross section and
Fig. 2a side elevation partly in section of a suction tube of a well known type
having our invention applied thereto.
A is the suction tule, B the hinged lid or door forming the bottom or floor of the
said tube and the grate or gril. ppare sets of teeth or pins of cast metal
which may he fastened to the upper or arched part of the tube A. by means of
Screw. We preferably leave in interval or open space between each of the
sets of teeth and arrange reh sureveding row of teeth so that a set of teeth in one
row is situated opposite the interval or open space in the adjoining row. In Fig. 1
one row of teeth is shown in solid lines and the next adjoining row in broken lines,
the teeth in solid lines in Fig. 1 corresponding with the row indicated by the
mumeral 1 in Fig. 2 and those in broken lines with the row indicated by the
numerul 2. We find in practice that a satisfactory result obtains if the several
rows of teeth are placed about twelve inches apart from each other.
Fig. 3 is a side view drawn to a larger scale of one of the teeth shewn in Figs. 1
and 2.
Figs. 4 and 5 illustrate an arrangement of fingers or tapered pins which we
have found to answer the purpose of our said invention.
Fig. 6 and 7 illustrate another arrangement we have successfully employed the
blocks quadrangular in cross section serving as in the case of the teeth and pins
shewn in the preceding figs. to obstruct the cotton in its passage through the
tube and to additionally agitate it and shake out therefrom dust and other
impurities.
But as the result of our experiments we prefer to employ the forms and arrange-
ment of teeth illustrated at Figs. 1, 2, and 3.
We do not wish to include or to claim as part of our said invention the arranging
of the metal bars forming the grate or grid of a suction tube longitudinally instead
of transversely of the tube as stated in the latter part of our Provisional
Specification.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The application to the suction tubes or trunks of cotton opening machines of
internal projecting teeth, pins, fingers, or other equivalent obstructing medin
substantially as hereinabove described and shown in the drawings for the purpose
set forth.
