PROVISIONAL SPECIFICATION.
Improvements in Air Humidifiers.
We, HANDEL BEECH of 35 Elm Bank, Heaton Chapel near Manchester,
Lancashire, Engineer and JOSEPH SHAW of Albert Brass Works, Lockwood,
Huddersfield, Yorkshire, Brass Founder and Finisher, do hereby declare the nature
of this invention to be as follows:-
This invention relates to what are known as air humidifiers, which are installed
in mills, factories, workshops and other places for washing and purifying the air
therein, freeing it from injurious gases, and moistening it to such a degree as is
deemed most suited to the comfort and health of the workpeople and to the various
processes of manufacture carried on or goods stored, or worked, in the rooms
provided with the apparatus.
The object of our improvements is to construct the jet and parts so as to avoid
the objectionable features of air moisteners and to considerably enhance their
efficiency.
In carrying out our invention we employ a suitable cylindrical case, or sheath,
within which is supported a conical or tapered jet or nozzle coupled to an inlet pipe
for supplying water thereto, and at the bottom of the said case is secured a tray
or dish.
Within the nozzle or jet is placed a conical or tapered plug or spindle of smaller
diameter than the internal diameter of the jet or nozzle, said plug being adjustable
and having at its lower end a projecting shoulder or enlarged tip.
The plug or spindle is supported by a suitable bridge piece centrally of the jet,
or concentric therewith, and a stuffing box or boxes is or are employed to seal the
upper end of the jet and make the joints watertight, these also allowing of easy
removal of the parts for cleaning and repairing purposes.
The water admitted to the aforesaid jet or nozzle is obtained from any suitable
source giving the requisite pressure, and may be cold or hot to cool or warm the
air passing through the humidifier.
The position of the shoulder or tip, at the lower end of the plug or spindle, in
relation to the mouth of the jet, is so adjusted, that, as the water is forced through
and out of the jet or nozzle, it impinges on the said shoulder and is thereby split
up into a very minutely divided spray and distributed equally on all sides over an
area confined within the casing and into which no part of the jet projects.
By this means we are enabled to split up the water thoroughly and so
distribute it that the greatest efficiency is obtained for moistening or saturating
purposes, and there is no liability of coarser particles or heavy drops of water
being sent down and carried into the room to the injury of machinery or goods
therein.
The jet of water induces a strong current of air to pass in and through the
apparatus, making its entrance and exit to and from the casing by suitable
passages or openings in the latter, and passing through the minutely divided spray
of water which washes, purifies and charges it with sufficient moisture to sustain
the health and comfort of the people engaged in the room and the atmospheric
conditions requisite for the work being carried on.
More than one jet may be employed, if necessary, and the case
animated accordingly
or sheath

page_text: The jet and parts described are simple and not liable to get out of order, and by
filtration of the water before discharging into the jet or nozzle, there is no danger
of the thoroughfare therein becoming choked up.

Improvements in Air Humidifiers.
We, HANDEL BEECH, of 35 Elm Bank, Heaton Chapel, near Manchester,
Lancashire, Engineer and JOSEPH SHAW, of Albert Brass Works, Huddersfield,
Yorkshire, Brass Founder and Finisher, 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 what are known as air humidifiers, which are installed
in mills, factories, workshops & other places, for washing & purifying the air
therein, freeing it from injurious gases & moistening it to such a degree as is
deemed most suited to the comfort & health of the work-people & to the various
processes of manufacture carried on, or goods stored, or worked in the rooms
provided with the apparatus.
The object of our improvements is to construct the jet & parts, so as to avoid
the objectionable features of air moisteners & to considerably enhance their
efficiency.
In carrying out our invention we employ a suitable cylindrical case, or sheath,
within which is supported a conical or tapered jet or nozzle coupled to an inlet
pipe for supplying liquid thereto, & at the bottom of the said case is secured a
tray or dish.
Within this nozzle or jet is placed a conical or tapered, or straight plug or
spindle of smaller diameter than the internal diameter of the jet or nozzle, the
said plug being adjustable, & having at its lower end a projecting shoulder or
enlarged lip.
The plug or spindle is supported by a suitable bridge piece centrally of the jet,
or concentric there-with, & a stuffing box or boxes is or are employed to seal the
upper end of the jet & make the joints water-tight, these also allowing of easy
removal of the parts for cleaning or repairing purposes. The water admitted to
the aforesaid jet or nozzle is obtained from any suitable source giving the requisite
pressure, & may be cold or hot, to cool or warm the air passing through the
humidifier.
The position of the shoulder or lip at the lower end of the plug or spindle, in
relation to the mouth of the jet, is so adjusted that as the liquid forced through
and out of the jet or nozzle it impinges on the said shoulder & is thereby split up
into a very minutely divided spray & distributed equally on all sides over an area
confined within the casing.
By this means we are enabled to split up the liquid thoroughly & so distribute
it, that the greatest efficiency is obtained for moistening & saturating purposes,
& there is no liability of coarser particles, or heavy drops of liquid being sent
down & carried into the room, to the injury of machinery or goods therein.
The jet of liquid induces a strong current of air to pass in & through the
apparatus, making its entrance & exit to & from the casing by suitable passages
or openings in the latter, & passing through the minutely divided spray of liquid,
which washes, purifies & charges it with sufficient moisture to sustain the health &
comfort of the people engaged in the room, & the atmospheric conditions requisite
for the work being carried on.

page_text: More than one jet may be employed, if necessary & the case or sheath
constructed accordingly.
The jet & parts described are simple & not liable to get out of order, & by
filtration of the liquid before discharging into the jet or nozzle, there is no
danger of the thoroughfare therein becoming choked up.
Other known apparatus or jets have an arm that projects from above the water
outlet, & is brought down to below the outlet. This is very objectionable, for the
water strikes the aforesaid arm & collects itself & forms a running stream,
which, when it reaches the tray or receiver, is carried forward unbroken, or the
beads of the operatives, therefore we introduce the internal spindle to hold or
contain a suitable receiver as set forth in accompanying drawings & numbered
from 1 to 10. But we do not confine ourselves to enclosed design as other suitable
designs will answer the same end, for instance, we can have a fixed spindle & a
movable delivery piece, to be raised & lowered to suit the density required.
Our invention is illustrated in the accompanying drawings, in which,
Fig. 1 is external view of the jet, and Fig. 2 internal or sectional view thereof.
1. is an internal spindle, which is made to regulate the outlet, so that a fine or
coarse spray can be given.
2. is a lock nut, to lock the internal spindle to prevent it from moving when
once it is set.
3. is an hollow screw to press down a packing sufficient to prevent the steam,
water, or other liquids from rising.
4. is a receiver to hold the packing or stuffing so as to prevent the water rising.
5. is the threaded portion known as a nipple for connecting the supply pipe.
6. is the body of the jet.
7. is a cross-piece, or guide piece to stiffen the lower portion of internal spindle.
8. is the threaded portion, which hold the jet in position.
9. is the bottom portion of internal spindle having an anular lip, on which the
water impinges.
Having now particularly described & ascertained the nature of our said inven-
tion, & in what manner the same is to be performed, we declare that what we
claim is :-
First. A jet, having an internal spindle tapered or straight of smaller diameter
than the internal diameter of the jet or nozzle, with an enlarged end having an
anular lip on which the water impinges, & adjustable, so that a fine or coarse
spray can be given.
Second. A jet, or nozzle having an internal spindle, tapered or straight, of a
smaller diameter than the internal diameter of the jet, or nozzle, with an enlarged
end having an anular lip & a movable cap or nozzle to rise & fall to the density of
spray required.
