Specification
I, WILLIAM PHILLIPS THOMPSON F.C.S. M.I.M.E. of the Agency for Foreign
Patent Solicitors 6, Lord Street, Liverpool and 6 Bank Street, Manchester both in
the County of Lancaster and 323 High Holborn in the County of Middlesex, Civil
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 :-
In order to moisten the air as required in spinning mills, very fine sprays of water
projected from several nozzles are caused to impinge against suitable surfaces and the
fine cloud of water particles thus obtained is introduced along with the air from the
ventilator into the work rooms.
The apparatus hitherto used have serious disadvantages, both in the heavy construc-
tion of the dispersing device (the device for forming the cloud of water) and also in
the connection of the latter with the ventilating apparatus; the light and speedy
cleaning of the nozzles which should be the case in practice is not also effected, nor
is the proper degree of moisture imparted to the air so that the machinery and other
objects in the work room shall be maintained in an effective state of moisture.
All these disadvantages are avoided by the central-air-moistening apparatus forming
the object of the present invention and in such a manner that, first, any number
whatever of nozzle openings are so united together that the whole of these-nozzles-is
them are easily accessible, and can be cleaned in a short time by brushing them after
the lid of the nozzles has been removed; whereas formerly, each nozzle had to be
cleaned singly by means of a fine needle after the dispersing apparatus had been
serewed off unscrewed. Secondly, only the finest spray of water is introduced into
the air from the ventilator for the full current of the latter does not meet the cloud of

page_text: fine water produced and does not carry away fine and coarse water spray together
and indiscriminately as has hitherto been the case, but acts upon the dispersed water
only partially and with lessened force, so that the air only carries away the finest
water particles, whilst the coarser ones sink down owing to their gravity and are
collected in a suitable reservoir ad hoc. Lastly; it must also be noticed that by
reducing the number of nozzles not only an essential simplification of the apparatus is
obtained, but that by the suppression of the cocks that were hitherto necessary a great
saving of cost is also effected.
In the accompanying drawing- drawings
Figures to show two forms of construction of the central nozzle, whilst
Figure 5 represents the moistening apparatus fitted with the central nozzle.
On the body A of the nozzle (Figure 1), which is connected with the pipe bringing
the water, is screwed the upper part B which is closed by the lid C. On the edge of
this upper part B are arranged the conical nozzle openings a each terminating on the
outside by in a fine aperture, so that after serewing-off unscrewing the lid C, small
nozzles placed on a circumference-are-obtained the nozzle openings on the upper edge
of B are exposed. The water flowing into the central nozzle issues consequently in
fine sprays which strike against stop surfaces D (Figure 5) which can be closed or
have the shape of a sieve or consist of several plates; the water sprays are being
dispersed on striking against these surfaces. In producing the required fineness
of the individual sprays needed to obtain a serviceable dispersing action, the apertures
of the nozzles are made extremely fine, and it is therefore necessary to retain the
impurities which the water under pressure always contains before the latter issues
out of the central nozzle. For this purpose there is inserted between the body A of
the nozzle and the upper part B, a sieve 6 (Figure 1). This sieve is made water-
tight, both with the body A and the upper part B, by means of an inlaid packing
ring d, Figures 1-3 and 4, whilst the cross piece e in the upper part B takes up the
pressure exerted by the water on the sieve and prevents the latter from getting
torn.
The sieve b retains therefore the impurities contained in the water under pressure.
If, however, in course of time, the nozzle apertures should become stopped, the lid C,
which is held down by means of the screw f screwed down in the eress piece e, is
removed after loosening taking out the said screw; and all the nozzle apertures a lay
open to examination being thereupon exposed, so that, by means of a brush, they can
all be easily cleaned at once. The cleaning of all the nozzles does not require any
more time than that required formerly to clean one single nozzle; besides this the
central nozzle requires occupies less room and the cost of its manufacture is far less
than that of the dispersing contrivances generally used to produce fine water sprays,
in which a nozzle is required for each spray jet.
The cleaning of the sieve is effected as easily as that of the nozzle apertures a.
For this purpose the upper part B is screwed-off unscrewed from the body A of the
nozzle the sieve b, which lies now being then free, can be taken off and brushed off.
After replacing the sieve in-its-former-position and screwing on the lid C, the
central nozzle is again in working order, ready for use.
In the central nozzle shown in section in Figure 1 and in plan in Figure 2 (the
lid being supposed-to-have having been removed) the water jets obtained are directed
horizontally If oblique jets are be required, the central nozzle shown in section in
Figure 3, and in detail in Figure 4 on a larger scale, can be used advantageously.
This nozzle consists likewise of the body A, the upper part B and the lid C. The sieve b,
made water tight by means of the packing ring d, retains likewise the coarser parts
of the impurities of in the pressure water, but does not bear, as in the foregoing
construction, against a eross piece connected-with formed in the top part, but
against a strong piece of perforated metal which takes up the pressure of the
water and prevents the sieve from getting torn. The plate & lies of-course on
the top of the packing ring d, which renders both the body A and upper part B
water-tight, so that the water under pressure cannot run round the edges of the
plates band.

page_text: The nozzle apertures a are oblique, and indeed are formed partly in the upper
dge of the top part B contains-one-part-of-the-nozzles'-apertures, whilst and
partly in the lower edge of the lid C. eontains the other-part-of-the-apertures.
Thus when the lid Chas been removed, the parts forming the apertures of the
ozzles lay lie open to view and are easily cleaned by means of a brush. However,
s the wear cannot be avoided and in order that the apertures of the nozzles can
e re-bored, the direction of the latter is such that after removing the upper-part
B-and-the-id-6; a nee lle can he introduced in the said apertures as shown by
he dotted lines on Figure 3.
The body A, the upper part B, and the lid C, are held together by means of a
clamp E, the hooked ends g of which rest against the projections of on the
body A, whilst the pressure screw, passing through the clamp, presses on
the lid C.
In order to be able to bring the lid exactly on the upper part B, so that the parts
forming by their reunion the nozzles may be exactly opposite to each other. the upper
part B and the lid C are provided with centring pins, or the centring device repre-
sented is applied. In the latter case, there are arranged on the upper part two flaps
projections forming a groove. After the openings a in the upper part and lid have
been worked on, a plate i, fitting exactly in the groove left, between the flaps
projections h. is soldered to the lid C. The plate secures the exact replacement
The upper
of the lid C on the upper part B. always in the same-position-
part B and the lid C can also be united be made in one piece. The nozzle
openings are then not formed in two parts, but are bored conical with an acute
taper.
The jets of water issuing from the central nozzle impinge, as already mentioned,
against a stop surface D (Figure 5) and are there dispersed. It is not possible, however,
to transform these water jets in a uniformly fine shower; there will always be a mixture
of fine and coarse parts. In order that the air shall may not be too moist, only
a very fine and uniformly dispersed spray can be used; it is therefore necessary to
effect the separation, not effected hitherto, of the coarser jets particles from the finer
ones before the moistened air is admitted into the work room.
In order to attain this end, the velocity of the air passing through the dispersing
apparatus is so reduced that it is enabled only to carry away the finest-dispersed
finer spray, whilst the coarser sinks down in consequence of its own gravity, and
is not led into the ventilating stream itself. The dispersing apparatus X is arranged
below the air pipe F in a vessel collecting which collects the drops of water, and
is covered with a bonnet H, which guides the air passing through the recipient
in the proper direction, and collects any of the jets of water that are somewhat
oblique, and in the ordinary methods of dispersing are decidedly a
cause of
wetting. The drip pan G has, below the central nozzle, an opening under which
is applied a vessel I for the purpose of collecting the coarse spray that sink runs
down.
The ventilation air is led into the pipe F in any suitable manner, and whether this
take place from the side or from below, the aspirating or compressing-netion of this
suction of the current of air will draw air through the opening at the bottom of
the disperser X and through the spray of water produced by the stop surfaces
inserted between the nozzle and this the wall, which stop surfaces may have the form
of sieves, or consist of separate plates. The velocity of this-aspirated-air the air
sucked in is certainly much less than that of the ventilation air proper and will be
only able to carry away the lightest, consequently the finest, water particles, before
it inixes with the ventilating current. In order to be able to regulate the speed
of the air drawn in so as to exactly meet the conditions of moisture of air imposed
in each special case, the cross section of the passage of for the air between the
collecting vessel and the drip pan is made variable. This variability of the section
of the air passage can be effected either by causing the collecting vessel 1 to be
approximately near nearer or farther from the vessel G according to requirements;
or by more or less closing an opening on the air passage by means of a slide.

page_text: In the arrangement shown en in Figure 5, the slide used is circular. The collecting
vessel I is connected with the drip pan G by means of a ring c, provided with
rectangular openings. Over this ring is arranged another ring K provided likewise
with similar openings. By turning the latter ring, the openings of the former may
be more or less covered.
The quantity of air flowing into the disperser, and with-it at the same time the
velocity of the air flowing through the water spray, can be regulated with a great
nicety, so that only those particles of water are carried away which this the latter
current of air can carry at the speed at which it possesses flows. All the heavier
particles sink down and are collected in the collecting vessel I, out of which the
collected water is removed, from time to time, or runs out.
By varying the section of the passage admitting air to the apparatus, it is possible
to regulate at will the rate quantity of moisture to be supplied by the apparatus. This
is a point of the greatest importance, because the degree of moisture to be communicated
to the air must correspond to the weather, and to the branch of manufacture carried
out in the working rooms.
When the air regulator K is closed, the cloud of water formed in the disperser
remains in the latter, and no particular moistening of the air will be is noticeable.
In the most usual application of separate nozzles, the moistening capacities of the
apparatus could can only be regulated by closing one or several nozzle cocks; whilst in
the new apparatus, the regulation is effected by regulating the current of air traversing
the apparatus. The nozzle remains therefore unhindered at work.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondent, I declare that what I claim is :-
In apparatus for moistening air
1. The division of the current of air to be moistened in such a manner that one
part of the same flows into the dispersing apparatus with a less velocity than that
of the other portion of air which is part led directly into the pipe F, for the purpose
1st of effecting the separation of the finer spray from the coarser spray, both of which
are produced during the dispersing action of the apparatus, so that only the fine spray
is carried away whilst the coarser one, that is the heavier, one, sprays falls down, and
2ndly of being able-to-regulate regulating the proportion of moisture given by the
moistening device according to requirement.
2. The application of a central nozzle distinguished by the arrangement of any number
of notches a cut on the edge of a nozzle-upper-part B which will, when closed by
laying thereon a lid C, form nozzles for the purpose-of uniting on a common hollow
part any number-whatever of nozzles; and capable of being able-to-effect-an-easy
eleaning of the latter easily cleaned, in conjunction with a surrounding stop surface
such as D against which jets, issuing from the said nozzles, impinge and become dispersed
in a minutely-divided spray.

Patent Solicitors 6, Lord Street, Liverpool and 6 Bank Street, Manchester both in
the County of Lancaster and 323 High Holborn in the County of Middlesex, Civil

In order to moisten the air as required in spinning mills, very fine sprays of water

fine cloud of water particles thus obtained is introduced along with the air from the
ventilator into the work rooms.
The apparatus hitherto used have serious disadvantages, both in the heavy construc-
tion of the dispersing device (the device for forming the cloud of water) and also in
the connection of the latter with the ventilating apparatus; the light and speedy
cleaning of the nozzles which should be the case in practice is not also effected, nor
is the proper degree of moisture imparted to the air so that the machinery and other
objects in the work room shall be maintained in an effective state of moisture.
All these disadvantages are avoided by the central-air-moistening apparatus forming
the object of the present invention and in such a manner that firstly, any number
whatever of nozzle openings are so united together that the whole of these nozzles is
easily accessible and can be cleaned in a short time, by brushing them after the lid
of the nozzles has been removed whereas formerly each nozzle had to be cleaned
singly by means of a fine needle after the dispersing apparatus had been screwed off.
Secondly only the finest spray of water is introduced into the air from the ventilator
for the full current of the latter does not meet the cloud of fine water produced and
does not carry away fine and coarse water spray together and indiscriminately as has
hitherto been the case, but acts upon the dispersed water only partially and with

page_text: .
lessened force, so that the air only carries away the finest water particles, whilst the
coarser ones sink down owing to their gravity and are collected in a suitable reservoir
ad hoc. Lastly; it must also be noticed that by reducing the number of nozzles not
only an essential simplification of the apparatus is obtained, but that by the
suppression of the cocks that were hitherto necessary a great saving of cost is also
effected.
In the accompanying drawing-
Figures 1 to 4 show two forms of construction of the central nozzle whilst
Figure 5 represents the moistening apparatus fitted with the central nozzle.
On the body of the nozzle A (Figure 1,) which is connected with the pipe bringing
the water, is screwed the upper part B which is closed by the lid C. On the edge of
this upper part B are arranged the conical nozzle openings a terminating on the
outside by a fine aperture, so that after screwing off the lid C, small nozzles placed on
a circumference are obtained. The water flowing into the central nozzle issues con-
sequently in fine sprays which strike against stop surfaces D (Figure 5) which can
be closed or have the shape of a sieve or consist of several plates, these water sprays
are dispersed on striking against these surfaces. In producing the required fineness
of the individual sprays needed to obtain a serviceable dispersing action, the apertures
of the nozzles are made extremely fine, and it is therefore necessary to retain the
impurities which the water under pressure always contains before the latter issues
out of the central nozzle. For this purpose there is inserted between the body A of
the nozzle and the upper part B, a sieve 6 (Figure 1). This sieve is made water-
tight, both with the body A and the upper part B by means of an inlaid packing
ring d, Figures 1. 3. and 4, whilst the cross piece e in the upper part B takes up the
pressure exerted by the water on the sieve and prevents the latter from getting
torn.
The sieve retains therefore the impurities contained in the water under pressure.
If, however, in course of time, the nozzle apertures should become stopped, the lid
held down by means of the screw f screwed down in the cross e is removed after
loosening said screw and all the nozzle apertures a lay open to examination, so that by
means of a brush, they can all be easily cleaned at once. The cleaning of all these
nozzles does not require any more time than that required formerly to clean one
single nozzle besides this the central nozzle requires less room and the cost of its
manufacture is far less than that of the dispersing contrivances generally used to
produce fine water sprays, in which a nozzle is required for each spray.
The cleaning of the sieve bis effected as easily as that of the nozzle apertures a.
For this purpose the upper part B is screwed off the body of the nozzle A, the sieve b
which lies now free can be taken off and brushed off.
After replacing the sieve bin its former position and screwing on the lid C, the
central nozzle is again in working order, ready for use.
In the central nozzle shown in section in Figure 1. and in plan in Figure 2 (the
lid being supposed to have been removed) the water jets obtained
are directed
horizontally. If oblique jets are required, the central nozzle shown in section in
Figure 3 and in details in Figure on a larger scale can be used advantageously.
This nozzle consists likewise of the body A, the upper part B and the lid C. The seive b
made water tight by means of the packing ring d, retains likewise the coarser parts
of impurities of the pressure water, but does not bear as in the foregoing construc-
tion against a cross piece connected with the top part, but against a strong piece of
perforated metal which takes up the pressure of the water and prevents the sieve
from getting torn. The plate lies of course on the top of the packing ring d,
which renders both the body A and upper part B water-tight, so that the water
under pressure cannot run round the edges of the plates 6 6.
The nozzle apertures a are oblique, and indeed the upper edge of the top part B
contains one part of the nozzles' apertures, whilst the lower edge of the lid C contains
the other part of the apertures. Thus when the lid C has been removed, the parts
forming the apertures of the nozzles lay open to view and are easily cleaned by means
of a brush. However, as the wear cannot be avoided and in order that the apertures

page_text: of the nozzles can be re-bored, the direction of the latter is such that after removing
the upper part B and the lid C, a needle can be introduced in the said apertures as
shown by the dotted lines on Figure 3.
The body A, the upper part B, and lid C, are held together by means of a clamp E,
the hooked ends of which, rest against the projection g of the body A, whilst the
pressure screw passing through the clamp, presses on the lid C.
In order to be able to bring the lid C exactly on the upper part B, so that the parts
forming by their reunion the nozzles, may be exactly opposite to each other, the upper
part B and the lid Care provided with centering pins or the centering device repre-
sented is applied. In the latter case there are arranged on the upper part two flaps h
forming a groove.
After the openings a in the upper part and lid have been worked
on, a plate i fitting exactly in the groove left between the flaps h, is soldered to the
lid C.
The plate i secures the exact replacement of the lid C on the upper part B always
in the same position. The upper part B and the lid C can also be united in one piece.
The nozzle openings are not formed in two parts but bored conical with an acute
taper.
The jets of water issuing from the central nozzle impinge as already mentioned,
against a stop surface D (Figure 5) and are there dispersed. It is not possible, however,
to transform these water jets in a uniformly fine shower; there will always be a mixture
of fine and coarse parts. In order that the air shall not be too moist, only a very
fine and uniformly dispersed spray can be used, it is therefore necessary to effect the
separation, not effected hitherto, of the coarser jets from the finer ones before the air
is admitted into the work room.
In order to attain this end, the velocity of the air passing through the dispersing
apparatus is so reduced that it is enabled only to carry away the finest dispersed
spray, whilst the coarser sinks down in consequence of its own gravity, and is not led into
the ventilating stream itself. The dispersing apparatus X is arranged below the air pipe F
in a vessel collecting the drops of water, and covered with a bonnet H, which guides the
air passing through the recipient in the proper direction, and collects any of the jets
of water that are somewhat oblique, and in the ordinary methods of dispersing are
decidedly a cause of wetting. The drip pan G has below the central nozzle, an
opening under which is applied a vessel I for the purpose of collecting the coarse
sprays that sink down.
The ventilation air is led into the pipe F in any suitable manner, and whether this
takes place from the side or from below, the aspirating or compressing action of this
current of air will draw air through the opening at the bottom of the disperser X and
through the spray of water produced by the stop surfaces inserted between the nozzle
and this wall, which stop surfaces may have the form of sieves, or consist of separate
plates. The velocity of this aspirated air is certainly much less than that of the
ventilation air proper and will be only able to carry away the lightest, consequently
the finest, water particles, before it mixes with the ventilating current. In order to
be able to regulate the speed of the air drawn in so as to exactly meet the conditions
of moisture of air imposed in each special case, the cross section of the passage of
the air between the collecting vessel and the drip pan is made variable. This
variability of the section of the air passage can be effected either by causing the
collecting vessel I to be approximately near the vessel G according to requirements;
or by more or less closing an opening on the air passage by means of a slide.
In the arrangement shown on Figure 5, the slide used is circular.
The collecting
vessel I is connected with the drip pan G by means of a ring c, provided with
rectangular openings. Over this ring is arranged another K provided likewise with
similar openings. By turning the latter ring, the openings of the former may be
more or less covered.
The quantity of air flowing into the disperser and with it the velocity of the air
flowing through the water spray, can be regulated with a great nicety, so that only
those particles of water are carried away which this air can carry at the speed it
possesses. All the heavier particles sink down and are collected in the collecting

page_text: vessel I, out of which the collected water is removed, from time to time, or runs
out.
By varying the section of the passage admitting air to the apparatus, it is possible
to regulate at will the rate of moisture to be supplied by the apparatus. This is a
point of the greatest importance, because the degree of moisture to be communicated
to the air must correspond to the weather, and to the branch of manufacture carried
out in the working rooms.
When the air regulator K is closed, the cloud of water formed in the disperser
remains in the latter, and no particular moistening of the air will be noticeable.
In the most usual application of separate nozzles the moistening capacities of the
apparatus could only be regulated by closing one or several nozzle cocks, whilst in
the new apparatus the regulation is effected by regulating the current of air traversing

page_text: 1, JOHN UPSDALE of 4 Falcon Avenue, Falcon Street, in the City of London,
Merchant, 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 relates to the manufacture of gloves of warp fabric which are found
to wear out most quickly at the tips of the fingers.
According to this invention the part of the fabric to form the tips of the fingers is
thickened during the process of manufacture by laying the threads over or under, or
over and under, more needles than is done when forming the remainder of the fingers
and the body of the glove.
For example, if the body of the glove as far as the tips of the fingers is made with
one, two or more guide bars lapping over, or over and under, one or more needles,
they shall, for the purpose of thickening the fabric forming the tips of the fingers, be
made to lap over, or over and under, more than one or two. needles as may be desired
to produce the necessary thickness.
Figure 1 is a diagram of part of a length of warp fabric with alternate bands of
thickened and unthickened work with lines marked upon it to indicate the shape of
the parts which are to be cut from it.
Figure 2 is a diagram of the way in which each of the threads are lapped
under and over the needles to produce ordinary unthickened work and Figures 3
and 4 are diagrams of the way in which they are laid under and over the needles to
produce the thickened bands.
The construction of warp knitting machinery is well understood.
In working the machinery to produce a length of fabric with alternate thickened
and unthickened bands the machinery is set to work in the ordinary manner for
producing plain unthickened work. When a band of the required width has been
made the machine is stopped and the two bars which carry the two sets of thread
eyes are disconnected from the cams by which they were previously traversed to and
fro and by which the thread eyes as they were swung to and fro between the needles
were made to lap their threads over and under the needles in the ordinary manner
and as is shewn by the diagram Figure 2.
Other cams are then set to act upon the two bars and these cams are of such a
shape as to give to the bars an increased traverse and to cause the thread eyes
which they carry each to work with three needles in place of with two as they
did previously.
The thread eyes of the bottom bar are by the cams now brought into action made
to lay their threads under and over the needles in the way shewn in the diagram
Figure 3 and the thread eyes of the top bar are made to lay their threads under and
over the needles in the way shewn at Figure 4.

page_text: Pieces of the shape marked a in the diagram Figure 1 are subsequently cut from
the fabric produced in the above manner each to form the main portion of a glove.
Other pieces marked 6 are also cut from the fabric as indicated by the diagram to
form the thumb pieces. These thumb pieces are sewn to the slits c cut through the
pieces a as is usual.
The fabric may be made from any material used in the manufacture of warp fabrics
such as silk, spun silk wool, cotton, Lisle or admixtures of these.
Having now particularly described and ascertained the nature of my said
invention and what manner the same is to be performed I declare that what I
claim is :-
1. The herein before described process for the manufacture of gloves consisting in
first forming a warp fabric with alternate broad bands of ordinary warp fabric and
narrow bands of thicker work than cutting from such fabric gloves with the tip
ends of the fingers cut from the thickened band and the remainder from the
broad band.
2. The manufacture of warp fabrics suitable for being cut into gloves with alternate
bands of plain work from which the greater part of the glove is to be cut and
bands thickened as herein before described from which the tip ends of the fingers
are to be cut.
