PROVISIONAL SPECIFICATION.
Improvements in Trunks for Cotton Openers and similar Machines.
I WALTER FROST of Roomfield Lane, Todmorden in the County of York, Machine
Fitter, do hereby declare the nature of this invention to be as follows:-
My invention relates to trunks or pipes used in combination with cotton openers
and similar machines for conveying the cotton or other materials to and from said
machines. These trunks are ordinarily made of plain sheets of iron bent into a
semicircular shape at the upper part of the trunk with vertical continuations, to
which grids composed of flat or other bars are fastened by bolts or equivalent
means. The underside of the trunks is closed by doors usually binged at one side
and secured by a spring latch at the other. The cotton or other material is drawn
by fans through the trunk and over the grids and by their rubbing action a partial
opening and cleaning is produced. The dirt falls between the bars of the grids.
The doors are opened on the average once a day, when the dirt is supposed to drop
from between the bars of the grids. Some of the dirt however does not drop and has
to be removed by means of iron rods pushed up between the bars, the dirt being thus
pulled out. Sometimes the part of the trunk above the grids through which the
cotton or other material passes gets choked, and then it is a difficult matter to loosen
it, because the inside of the trunk is almost inaccessible. The object of my invention
is to remedy this inconvenience, to facilitate the cleaning of the grids and to increase
the opening efficiency of the trunk, which I effect in the following manner: I
construct the upper part of the trunk of corrugated sheet iron. The corrugations are
across the trunk and rub the cotton or other material passing through the trunk and
assist in opening it out. I do not fix the grids to the sides of the trunk, but upon
doors which by preference are arranged at the underside or bottom of the trunk, but
may be arranged at the side of the trunk. When the doors are opened, the grids
come down or out with them and are entirely exposed, so that they can be cleaned
with facility. The opening of the doors also lays the interior of the trunk quite open
and makes it easily accessible, so that when the trunk becomes choked, the doors need
only be opened, when the material accumulated at some part of the trunk tumbles out
or can be easily removed.

COMPLETE SPECIFICATION.
Improvements in Trunks for Cotton Openers and similar Machines.
I, WALTER FROST, of Roomfield Lane, Todmorden, in the County of York Machine
Fitter, 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:
My invention relates to trunks or pipes used in combination with cotton openers
and similar machines for conveying the cotton or other materials to and from said
machines.
These trunks are ordinarily made of plain sheets of iron bent into a semi-circular
shape at the upper part of the trunk with vertical continuations, to which grids com-
posed of flat or other bars are fastened by bolts or equivalent means.
The underside of the trunks is closed by doors usually hinged at one side and
secured by a spring latch at the other.

page_text: The cotton or other material is drawn by fans through the trunk and over the grids
and by their rubbing action a partial opening and cleaning is produced. The dirt
falls between the bars of the grids. The doors are opened on the average once a day,
when the dirt is supposed to drop from between the bars of the grids. Some of the
dirt however does not drop and has to be removed by means of iron rods pushed up
between the bars, the dirt being thus pulled out. Sometimes the part of the trunk
above the grids through which the cotton, or other material passes gets choked and
then it is a difficult matter. to. loosen it, because the inside of the trunk is almost
inaccessible.
The object of my invention is to remedy this inconvenience, to facilitate the cleaning
of the grids and to increase the opening efficiency of the trunk, which I effect in the
following manner.
I construct the upper part of the trunk or arc of corrugated sheet iron. The corru-
gations are across the trunk and rub the cotton or other material passing through the-
trunk and assist in opening it out. I do not fix the grids to the side of the trunk,
but upon doors which, by preference, are arranged at the underside or bottom of the
trunk, but may be arranged at the side of the trunk. When the doors are opened,
the grids come down or out with them and are entirely exposed, so that they can be
cleaned with facility. The opening of the doors also lays the interior of the trunk
quite open and makes it easily accessible, so that when the trunk becomes choked, the
doors need only be opened, when the material accumulated at some part of the trunk
tumbles out or can be easily removed.
t
Such being the nature and object of my said invention the following is a complete
description of same reference being had to the accompanying drawings in which:-
Fig. 1 is a side elevation of my improved "trunk" for cotton openers and other-
similar machines.
Fig. 2 is a similar view to Fig. 1 but shewing the door of the same opened.
Fig. 3 is an end elevation of Fig. 1.
Fig. 4 is an end elevation of the improved "trunk" shewing the door of the same
opened.
Fig. 5 is a sectional side elevation of a part of one of my improved trunks.
According to this my said invention I construct the upper part or arc of the trunk 1
of corrugated sheet metal, preferably iron. The corrugations 2 are across, or parallel
to the ends of the trunk, and serve to rub the cotton, or other material caused to pass
along and through the trunk, and thereby assist in opening out the fibre. The grids 33
are not fixed to the inside of the trunk, as heretofore, but upon a door or doors 4
which by preference are arranged at the underside, or bottom 5 of the trunk, so as to
open downwards, or in the direction of the floor, but it will be obvious that the side
or sides of such trunks may be utilized as a door or doors and made to carry the
grids 3. The said door or doors 4 is or are hinged as at 6.6 to the trunk, and when
closed is or are held in that position by the ordinary spring hooks or catches 7.7.
When the door, or doors 4 are opened the grids 3 are brought down, or turned out-
wards with it, or them (see Fig. 3) and are thus entirely exposed so that the grids 3
and the spaces between such grids are quite accessible and can with facility be
thoroughly cleaned.
The opening of the door or doors 4 also lays the interior of the trunk open, and
accessible, so that when the trunk becomes choked, the door or doors 4 need only be
opened; and turned on their hinges 6.6 when the material, or waste which has accu-
mulated in the trunk falls out, or is readily removed. The grids 8. are secured to the
inside of the door or doors 4, by set screws, nuts and bolts, or ordinary screws, 8.83
Having now particularly described and ascertained the nature and object of my
said invention, and in, what manner the same is to be performed, I declare that what
I claim.is.:-
1. Trunks for cotton openers and similar machines, the upper portion or are which
is corrugated, the bottom or the sides of the trunk forming a hinged door, or doors

page_text: and having the grids 3 affixed thereto as described and illustrated by annexed
drawings.
2. A cotton opener having a corrugated rubbing arc and a rubbing grid or grids
for purpose herein described.
