Improvements in Apparatus for supplying Cooled or Moistened Air
to Rooms and Buildings.
I, CHARLES DENTON ABEL of No. 28 Southampton Buildings, Chancery Lane in
the County of Middlesex, Consulting Engineer and Patent Agent 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 :-
The object of this invention is to provide a means by which cooled air or air charged
with moisture, can be blown or driven at will into any desired parts of rooms, halls,
factories and so on, in order that the air thereof may be readily kept at any desired
state of humidity or temperature. This invention is particularly applicable to spinning
rooms in mills where owing to the extreme dryness of the air large quantities of oil
are generally necessary for lubricating the machinery, which oil being taken up by
the threads in spinning or weaving is very hard to remove without destroying or
injuring the fabric spun or woven. Whenever this improved method and apparatus
is used, it has been found that the oil can be almost wholly supplanted by the use of
soap which soap is readily taken out of the fabric by the simple process of washing,
leaving the fabric in a much better condition than when it has to be freed from oil.
But the invention may also be readily and advantageously used in many other
buildings, rooms and halls, either as a cooling or ventilating system or for keeping the
air moist and not allowing it to become heated or dry.
Two forms of the improved apparatus are shewn in the accompanying drawings in
which Fig. 1 is a front elevation of the apparatus partly in section when placed in a
corner of the space to be supplied with moisture, the funnel or blower C, being capablo
of a partial rotation.
Figure 2 is a sectional plan of the same, Figure 3 is a side elevation of the same,
Figure 4 is a sectional plan of a modification Figure 4 is a part section on line X X.
The same letters indicate similar parts in the different figures.

page_text: A represents a reservoir or conduit from which the cooled or moistened air is drawn
by means of a revolving fan B and supplied to the rotating or oscillating blower C.
The charging of the air in this conduit with moisture may be brought about in
several ways, namely either by causing water to run along the top of the chamber and
to drip into the same through the slits c, figures 2 and so as to be taken up by the
air which is drawn forcibly past the slits from the perforated opening a connecting
with the outer air; or by forcing water through a pipe b, with nozzles at suitable
intervals passing through the conduit from which nozzles a spray of water is projected
into the air as shewn in figures 2, 3 and 4, or again by injecting steam from below as
shewn in figure, supplied through the steam pipe controlled by cock g.
When the apparatus is used for ventilation only, these appliances are not necessary,
but A becomes a simple conduit leading from a refrigerating chamber for the
supplying of cold air to the blower. From the forward end of this chamber or
conduit A. rises the revolving or swinging funnel or blower C, which is mounted upon
the vertical shaft E, supported by the bracket which is fastened to the ceiling or to any
other suitable support. The rotation or oscillation of this funnel will be presently
described.
The revolving fan B, is mounted upon a shaft e which turns in bearings, one of
which is inside the chamber A, and the other, either in the wall or some suitable
support outside the chamber, and is made to revolve by the pulley G, which derives
its motion by means of a belts from the driving wheel which is driven from a source
of power not shewn, and which is mounted upon the shaft j, hung upon bearings
secured to the wall or to posts provided for that purpose, or other suitable support.
Obviously, as the revolving fan B is made to rotate at considerable speed, it feeds the
air to the blower C, forcing it from the chamber A up, through and out of the funnel
or blower, the force of the blast depending, of course, upon the speed of rotation.
The funnel may be pointed in any desired direction, and hence the blast of moistened
or cooled air can be driven wherever it is needed. Although a revolving fan is prefer-
able to any other system of feeding the air from the conduit, to, through, and out of
the blower, there are other forms of fans which might do the work more or less
perfectly.
The figures 1, 2, 3 and 4 show the arrangement of an apparatus, the blower of
which makes a partial revolution.
The shaft j, is provided with a worm h, which drives the worm wheel i, the shaft of
which is supported by suitable bearings mounted upon posts or brackets on the wall,
or otherwise, if desired, and this shaft carries at its outer end the eccentric arm k,
which acts as a crank to drive the forked arm l, to which the other end is attached.
This forked arm 7, embraces the vertical shaft E, on which, as before stated the funnel is
hung and hence the rotation of the wheel i, imparts a to and fro notion to the blower
or funnel C.
The revolving fan B being in operation during this time, a continuous blast of
moistened air is blown out from the funnel as it rotates.
When it is desired only to throw this moistened or cooled air into certain specified
directions intermittently as occasion may require, the apparatus may also be con-
structed as shewn in figure 4, in which the worm wheel i, is horizontal instead of
vertical, mounted upon a vertical shaft which is supported by suitable posts or
bearings in a framework erected for that purpose, not shewn, and carries a crank m,
to the free end of which is secured the connecting rod n, the other end of which is
fastened to the arm o, which fastened to the shaft E, with which the funnel revolves.
The revolution of the worm-wheel i, throws or swings the funnel C alternately from
the position shewn in full lines, figure 4, to the position shewn in dotted lines, figure 4,
thus giving only that limited area for the effect of the blast that is required under
the particular circumstances, the throw or swing of the blower being determined by
the adjustment given to the respective crank arms m and o.
When it is desired to have the apparatus placed in the centre of the air space
to be supplied with moisture, the blower or funnel C is operated by any suitable
means so as to make a complete revolution round its vertical axis.

page_text: The operation of this apparatus is as follows:
Power being applied from a source not shown, to the driving wheel D, the said
wheel rotates the shaft j, and the worm, and by means of the belt s, the pulley G,
and with it, the shaft e, causing the fan B to rotate and create the desired blast, drawing
the air from the conduit A. Meanwhile the worm communicates its motion to the
worm wheel i, and through the crank k, and forked arm l, or through the cranks m
and o, and connecting rod n, to the funnel or blower C, which thus receives a revolving
or oscillating motion, as the case may be. The cooled or moistened air then being
drawn through the conduit A, the revolving fan B, and funnel or blower C, is
thrown out into the room either by a continuous rotary motion, to take in a full
circuit of the room or by an intermittent oscillating motion to take in a specified
portion only.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declaro that what I
claim is
1. The use for ventilating or supplying cooled or moistened air to rooms or
buildings, of apparatus consisting of the combination of a fan or blowing apparatus
with a conduit for conveying cooled or moistened air thereto from any desired
locality, and with a revolving or oscillating funnel or blower through which the
air drawn by the fan from the conduit is propelled thereby in any required direction
into the room or other locality, substantially as herein described.
2. In apparatus for supplying moistened air to rooms or other localities, the com-
bination with a fan or blowing apparatus B of a conduit A provided with means for
imparting moisture to air passing through the same to the said fan or blowing
apparatus which then propels the moistened air through a revolving or reciprocating
funnel or blower into the room or other locality, substantially as herein described
with reference to the accompanying drawings.
3. The construction of apparatus for supplying moistened or cooled air to rooms or
other localities combined and operating substantially as herein described with reference
to the accompanying drawings.
