PROVISIONAL SPECIFICATION.
Improvements in or connected with Carding Engines for Treating
Flax, Hemp, Jute, or other Fibre.
I, THOMAS JOHNSTONE PORTER, of Lisburn, in the County of Antrim,
Ireland, Flax Spinner, do hereby declare the nature of this invention to be as
follows
:-
This invention is designed to remove or carry away the dust from carding
engines and prevent such being dispersed through the room in which they are
operated which has hitherto been attended with extreme difficulty.
It applies more especially to carding engines to which have been fitted
appliances known as card feeders by which the fibres are lifted and introduced into
card in regulated quantities and which generate or produce almost as much dust as
the carding engine itself.
In carrying out and applying the invention I enclose or cover the card and the
feeder and also cover or box in the space embraced between the card and the
feeding appliance. To this enclosed space I fit or attach a number of exhaust
tubes or pipes also connected to an air duct or main from which the air is
exhausted by fans blowers or other exhausting apparatus. The air main may
run longitudinally or transversely of the apartment and may be placed above or
below the carding engines.
Parallel to the axes of the delivery rollers of the cards and in positions as close
to these as convenient I apply exhaust tubes or pipes furnished with perforations
or slits. These tubes may be provided with bell or funnel shaped mouths to draw
from a greater area and are connected with the air main or to the other exhaust
tubes which are connected therewith.
By this arrangement I am able to attack the dust at the points where it is
produced or escapes and so obviate or prevent its dispersal through the room.

Improvements in or connected with Carding Engines for Treating
Flax, Hemp, Jute, or other Fibre.
I, THOMAS JOHNSTONE PORTER, of Lisburn, in the County of Antrim,
Ireland, Flax Spinner, 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 is designed to remove or carry away the dust from carding
engines and prevent such being dispersed through the room in which they are
operated which has hitherto been attended with extreme difficulty.
It applies more especially to carding engines to which have been fitted
appliances known as card feeders by which the fibres are lifted and introduced
Ihmine ai

page_text: into the card in regulated quantities and which generate or produce almost as
much dust as the carding engine itself.
It will be fully described with reference to the accompanying drawings in
which sufficient of a carding engine is shown to illustrate the invention.
I enclose or cover the carding engine A and the feeder B and I also enclose
the space C embraced between the card A and the feeding apparatus B. To
the enclosed space I fit or connect one or more exhaust tubes or pipes D. The
exhaust pipes D are connected with a main air or exhaust duct E to which is
attached an exhaust fan blower or other exhausting apparatus by which a constant
exhaust is maintained. The exhaust duct or air main E runs preferably longi-
tudinally of the apartment and is set in the floor beneath the carding engines.
It may however be placed above the carding engines and if found more convenient
may run transversely of the apartment.
Parallel to the axes of the delivery rollers F of the carding engines and in
positions as close to those as convenient I apply branch exhaust tubes or pipes c
furnished with perforations or slits c¹. These tubes c may be provided with bell
or funnel shaped mouths cl to draw from a greater area and are connected with
the air main E or to the other exhaust tubes D which are connected therewith.
Another branch of the tubes opens beneath the feed lattice G.
Another exhaust tube C¹ may connect the interior of the card below the cylinder
with the exhaust duct E.
The sides of the card are all enclosed by panels or the like and the whole card
is practically covered in so that the exhaust draws from all parts where dust
would escape.
By this arrangement I am able to attack the dust at the points where it is
produced or escapes and so obviate or prevent its dispersal through the room.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what
I claim is
The combination with a carding engine for treating flax hemp jute or other
fibres of exhaust tubes or pipes such as D whereby a partial vacuum or exhaust
is formed below the card and pipes c placed in close proximity to the delivery
rollers or other place where the dust is generated and connected with an exhaust
máin or duct substantially as described.
