Improvements in Ventilating, Humidifying and Cleansing of Rooms,
Machinery and Textile Material.
ARTHUR WILSON METCALFE and JOHN BARBOUR MORRISON, of Grove Mill,
Belfast, Flax Spinners, do hereby declare the nature of this invention to be as
follows:-
This invention relates to means for humidifying textile material and removing
dust and dirt from hackling, preparing, and combing spinning and weaving
machinery, for textile fibres, and for clearing and purifying the air, and removing
the dust and dirt in rooms when such machinery is working.
The removal of the dust and vitiated air is performed by means of tubes or
ducts connected with an exhaust and placed upon or near the machines in posi-
tions near where the dust is being given off, so that the dust may be prevented
from circulating about the room, and settling on the material and machinery. Ducts
with small openings at frequent intervals are preferable so as to avoid too strong a
current of air at any one place. The position of the openings is also arranged so
as not to disturb the fibres in the sliver, but to carry away the dust and dirt that
may be given off.
These ducts may be provided with means for readily opening them or discon-
necting them for purposes of cleaning and flushing to remove any lodgment of
dirt inside.
Other ducts may also be provided capable of supplying fresh or humidified air
or vapour to the machines locally in such manner as to induce currents of air or
moisture towards the exhaust ducts where required affecting the material in its
passage.
Connections may be provided for attaching hose pipes to the exhaust. These
may be directed to any desired place for the purpose of removing the dust from
the machinery or the room.

page_text: 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 relates to means for humidifying textile material and removing
dust and dirt from hackling, preparing, combing, spinning and weaving machinery
for textile fibres and for clearing and purifying the air and removing the dust and
dirt in rooms where such machinery is working.
The manner in which these operations are performed is illustrated by reference
to the drawings herewith.
Fig. represents the end view of a hackling machine in sectional elevation.
The material is shewn suspended between the sheets of pins which hackle it down-
wards. Immediately below where the two sheets diverge is the usual dust board
of inverted V shape for conducting the dropping fibres and dust on to the revolv-
ing brushes. The under side of this dust board is formed into a duct a coupled
to an exhaust pipe b. The two sides of the duct a are perforated so as to admit
the dust laden air from the machine, whilst they are also so arranged as to be in
contact with the revolving brushes whereby they are cleared of the fibre and kept
operative.
Fig. 2, represents a section of part of a roving or gill spinning frame.
Figs. 4 and 5, represent in like manner a drawing frame in section and front
sectional elevation respectively.
In these figures the ducts a a connected to exhaust pipes bb are shewn in various
positions where they may be placed for drawing off the dust given off by the
material in its passage through the gills g, g.
Slits or holes or nozzles in the duets may be provided, continuously or at
intervals such as shewn in Fig. 5, where nozzles are shewn in some cases oppo-
site each gill g, g, or say between pairs of gills.
The heavier dust and droppings fall into the space ce beneath the gills and in
the case of Fig. 2 a certain amount is thrown off by the spindles into the space ff
beneath the frame. This dust and dirt and dropped fibre as also that about the
machinery and rooms generally is removed by means of a flexible hose pipe con-
nected to an exhaust pipe. The nozzle of this hose pipe is directed by the operator
to any part about the machinery or room and the dust is sucked up and carried
away thereby.
Connections may be provided at various intervals about the rooms to the
exhaust pipe, to which the hose may be attached.
In Fig. 5, a cap d on end of exhaust duct aa is made capable of removal
whereby a volume of air is admitted to flush the duct of any lodgment of dust.
In order to supply fresh or humidified air to the material on its passage through
the machines, ducts as at cc in Figs. 2, 4 and 5 may be so disposed beneath or
near the machines as to cause a current to pass through or near the material on
its way to the exhaust ducts aa.
Fig. 3 represents a section of a loom.
Here the humidified air or steam is supplied by the duct c through slits or per-
forations, against the warp, whilst an exhaust duct placed above carries away the
surplus moistened air.
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:-
1.) The method of ventilating hackling machines substantially as described and
illustrated by Fig. 1.
2.) The method of ventilating drawing roving and gill spinning frames sub-
stantially as described and illustrated by the ducts a a in Figs. 2, 4 and 5.
3.) The method of humidifying and ventilating applied to drawing, roving and
gill spinning frames substantially as described and illustrated by Figs. 2, 4 and 5.

page_text: 4.) The method of humidifying and ventilation applied to looms substantially
as described and illustrated by Fig. 3.
5.) The system of cleansing machinery and rooms of dust and the like by means
of hose pipes attached at any desired position in the room to an exhaust pipe, and
operated by hand substantially as described.
