PROVISIONAL SPECIFICATION.
Improvements in and in connection with the Exhaust Opener Lap
Machines used in the Preparation of Cotton and other Fibrous
Materials.
I THOMAS RODGERSON MARSDEN of 3 Barlow Street, Oldham, in the County
of Lancaster, Foreman, do hereby declare the nature of this invention to be as
follows:-
My said invention relates to the exhaust opener lap machines used in the pre-
paration of cotton and other fibrous materials, and consists in the application of an
auxiliary opening cylinder placed between the feeder and cylinder of such exhaust
openers, and so arranged with diverting valve or valves that the cotton or other
fibrous materials may be passed through this additional cylinder after leaving the
lattice feeder before it enters the exhaust opener cylinder. In the ordinary way
of working the exhaust opener, the cotton passes from the lattice feeder through
the dust trunks and into the cylinder or cylinders of the opener so that if different
classes or grades of cotton or other fibrous materials have to be treated in the
same opener, changes require to be made in the speed of the cylinders and beaters
which take up considerable time. By the introduction of the opening cylinder and
valve or valves between the lattice feeder and the exhaust opener cylinder, the
exhaust opener can be set suitable for the cleaner description of cotton which can
be passed direct from feeder to exhaust cylinder, but when working dirty cotton
it can be passed through the extra opening cylinder before entering the exhaust
cylinder..
The extra cylinder may be arranged either horizontally or vertically and may
be placed either between the feeder and trunks or between the trunks and the
opener cylinder.
Instead of one such extra cylinder between the feeder and the opening cylinder I
might provide two or more, which might be used either in conjunction or alternately
according to the grade of cotton to be treated.

COMPLETE SPECIFICATION.
Improvements in and in connection with the Exhaust Opener Lap
Machines used in the Preparation of Cotton and other Fibrous
Materials.
I THOMAS RODGERSON MARSDEN of 3 Barlow Street, Oldham in the County
of Lancaster, Foreman, 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 and accompanying drawings:-
-
My said invention relates to exhaust opener lap machines and feeders of the kind
used in the preparation of cotton and other fibrous materials.
In the working of the ordinary machines the cotton passes from the lattice feeder
through the dust trunk and into the cylinder casing of the opener so that if different
classes or grades of cotton or other fibrous materials have to be treated in the same
opener, changes require to be made in the speed of the cylinders and beaters in the
openers and such changes take up considerable time.

page_text: In my improved apparatus which is of a double acting character an auxiliary
opener is applied between the feeder and the exhaust opener and connecting pipes
and valves are provided so arranged as that the material say for example cotton
may be passed either direct to the exhaust opener or may be passed to the auxiliary
opener and thence to the exhaust opener.
Two arrangements for carrying my invention into effect are illustrated by the
accompanying two sheets of drawings.
In the combination illustrated in Sheet 1 an auxiliary horizontal opener is used,
the drawing in Sheet 2 showing the application of a vertical opener.
In Sheet 1 Fig. 1 is a side elevation and Fig. 2 a plan of the machinery con-
sisting of an exhaust opener (A) a lattice feeder (B) and an ordinary or suitable
horizontal or porcupine opener (C). The ordinary dust trunk is shown-curtailed
in length-at (d), such trunk being connected with the feeding machine by means of
a pipe (e) as is usual. In place of the ordinary uninterrupted pipe which conveyed
the cotton from the dust trunk (d) to the cylinder casing (a) of the exhaust opener I
apply a pipe (f) which is provided with connecting branches (g) and (h) which
proceed to and from the opener (C). Swing valves (i) (j) are applied at the
junctions of these branches with the main pipes. One of these valves is shown
on a larger scale in Fig. 5 of Sheet 2. The valve () is so mounted as that it can
be turned either across the main passage as in Fig. 5 or across the mouth of the
branch passage leading to or from the auxiliary opener.
When the two valves are turned across the main pipe as indicated by the dotted
lines in Fig. 2 the cotton passes from the feeder through the dust trunk and is
diverted through the branch pipe (g) into the casing of the opener (C) whence,
after being subjected to the action of such opener, it returns through the branch (h)
to the pipe (f) which conveys it to the opener (A).
When the valves are turned into position to close the mouths of the branch pipes
the cotton passes direct from the dust trunk to the opener (A) in the ordinary
manner.
"
"
The example illustrated by Figs. 3 and 4 (on Sheet 2) differs from Figs. 1 and 2
(on Sheet 1) only in that a vertical or Crighton opener (C) is used for the
auxiliary machine the branch pipes being altered to suit the construction of the
added opener. In this example the cotton passes downward from the pipe (ƒ)
into the branch (9) instead of sideways as in Figs. 1 and 2. It will be seen how-
ever that the branch pipes and valves may be so arranged as that the cotton may
pass out either downward or sideways in either case as may be preferred and also
if preferred the parts might be constructed for the cotton to pass upward from the
branch (h) into the pipe (f) or the connection of the pipe (h) with the casing (a)
might be otherwise suitably effected.
The auxiliary opener may be of any suitable construction.
Although in both examples the auxiliary opener is applied between the dust
trunk (d) and the machine (A) this is not imperative as if preferred for any reason
the auxiliary opener might be applied so that the cotton would be passed through
the auxiliary opener before entering the dust trunk (d).
Ordinary parts of the machine not necessary to the sufficient illustration of my
invention have been omitted from the drawings.
In the improved combination the machine (A) may remain suitably set to operate
upon the varieties of cotton which are comparatively clean and which would be
passed direct from the feeder without passing to the auxiliary opener, but when
operating upon dirty or low grade cotton the valves should be turned into position
to divert the cotton to the auxiliary opener C from which the cotton would then
pass to the machine A as hereinbefore mentioned.
I in some cases apply more than one auxiliary opener and arrange the passages
and pipes so that the cotton could be passed through one of such openers or
through more than one according to the grade or condition of the cotton being
treated.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is ;-
1. My new apparatus provided with means for making it act in a double
character, either upon comparatively clean or unclean fibres and consisting of the
parts substantially described and employed for the purposes set forth and indicated.
2. The feeder (B) and exhaust opener (A) of ordinary or suitable construction
arranged so as to be capable of being worked in conjunction with, or independently
of, an auxiliary opener, having pipes and valves constructed and arranged so that
cotton or fibrous material may, at will, be passed either direct from the machine (B)
to the machine (A) or be diverted so as to pass through the added opener as
set forth.
