Improvements in Apparatus employed for Imparting Humidity
to the Atmosphere within Workshops and other places.
I, ARTHUR SCOTT of Mitchell Street Newton Heath in the County of
Manchester Mechanical Engineer and Manufacturer do hereby declare the
nature of this invention and in what manner the same is to be performed to
be particularly described in and by the following statement:-
My present invention relates to means for imparting humidity to the atmosphere
within work shops, factories and other places and has for its object to arrange new
or improved apparatus which will impart said humidity in a more perfect and
economical manner that is possible with apparatus constructed as hitherto to attain
which I employ an apparatus substantially as illustrated in the accompanying
sheet of drawings in which
Fig. 1 is a sectional elevation of my improved apparatus fitted to the upper part
of a warehouse or factory.
Fig. 2 is a sectional plan taken on line a a of Fig. 1 and
Fig. 3 is a plan in detail of a wing or blade of the improved fan I preferably
employ with said apparatus.
Similar letters of reference denote corresponding parts in each view.
My improved apparatus is preferably fitted or fixed to the warehouse or factory
roof as shown at Fig. 1. C representing the slated part of roof and D the glazed
portion.
The said apparatus is composed of a tube E which is preferably rectangular in
cross section and is open at for the ingress of air to the humidifier from the
outside of the building and has also an opening at e³ for the ingress of air to the
humidifier from the inside of the building.
The tube E is arranged with a flap valve W which is carried on a spindle or
shaft w bearing in the sides of the tube E and the said valve W is operated by
means of a lever P having a cord or chain p' attached to each end thereof.
A suitable tube G which is preferably circular in cross sectional plan connects or
communicates the tube E with my improved humidifier which latter is composed of
a specially formed diffuser R arranged with a number of truncated branches
which have suitable conducting veins and openings for the purpose of properly
diffusing the moistened atmosphere or air and steam escaping therefrom into the
building.
The centre portion of the diffuser R is circular in form and corresponds in size to
the connecting tube G it is supported by means of a suitable bracket or hanger z to
the beam of the roof as shown and has arranged perpendicularly within it a
suitable shaft J which bears in the lower and upper part of said bracket or
hanger 2 and receives at its upper end either my improved form of fan K as
illustrated or any other form of air propeller as will be well understood.
A cone pulley O is secured to the lower part of the said shaft J and said pulley
is driven by means of a rope or belt o' which passes over a pulley of the latter
receiving motion from any convenient source.
The fan K is composed of specially formed wings K' that is to say the said
wings are constructed with a curve extending from centre to periphery as shown
on enlarged scale at Fig. 3.
Between the fan K and diffuser RI fix or arrange a number of steam jet
nozzles M which are supplied with either live or exhaust steam and a regulating
tap or cock m' is fitted to the supply pipe m' in order that the amount of steam
issuing from the nozzles M may be regulated as required.
Where preferred a perforated plate L may be fixed between the diffuser K and

page_text: the steam jet nozzles M in order to give more spread to the steam and to associate
the same well with the atmosphere brought in by the fan or air propeller K.
The air is drawn into the apparatus by the fan K either through the opening e
or by reversing the valve W through the opening e¹. In the latter case it will be
cool air drawn from the outside of the building and in the former case it may be
warmer air drawn from the inside of the building.
The air so drawn in by the fan K is humidified by the steam jets and then
diffused into the building by the diffuser R thereby humidifying the atmosphere
therein in an economical and perfect manner.
It will be obvious that where preferred the steam jet nozzles may be arranged
over above or on the opposite side to that shown of the fan K and the perforated
disc L would in that case be placed between the fan K and nozzles M.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be, performed I declare that what I
claim is :-
1. In apparatus employed for imparting humidity to the atmosphere within work
shops and other places the use of a tube such as E arranged with a valve W so as
to admit air to a diffuser or humidifyer either from the outside or inside of a
building substantially as described and illustrated.
2. The combination of a fan K working in a tube arranged with steam jet
nozzles substantially as described and illustrated and used for the purpose
specified.
