PROVIDIONAL DICITICATION
An Improved Fan-blower.
WILLIAM PERCY WILSON BROWNE ARTHUR EDWARD WILSON BROWNE
Merchants of 34 Ludgate Hill Birmingham in the County of Warwickshire,
and ROBERT SEBASTIAN BOZON Albion House Handsworth in the County of
Staffordshire do hereby declare the nature of this invention to be as follows:-
Two fans are keyed upon a spindle, or shaft, which is driven by means of a pulley
feathered upon the centre of the same.
These fans are keyed upon the spindle,
or shaft at different angles and the blast conducted from them into one air way by
means of a Y piece. This produces a much more powerful blast, and requires a
very much lower speed to be driven at.

We, WILLIAM PERCY WILSON BROWNE, ARTHUR EDWARD WILSON
BROWNE, Merchants of 34 Ludgate Hill Birmingham in the County of
Warwickshire, and ROBERT SEBASTIAN Bozon, Engineer of Albion House
Handsworth in the County of Staffordshire, 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 :-
Two, or more fans are keyed upon a spindle, or shaft, which is driven by means
of a pulley, steam engine, or other motor, feathered, or keyed upon the centre, or
either end of the same. These fans are keyed upon the spindle, or shaft at different
angles, and the blast conducted from them into one air way by means of a Y piece.
This produces a much more powerful blast, and requires a very much lower speed
to be driven at. Having now explained the nature of our invention, we will now
proceed to particularly describe in what manner the same is to be carried into
effect by the aid of the following drawings and descriptions.
Fig. 1. shews an elevation of the fan-blower.
Fig. 2. a plan of the same, with the cover of the fan cases removed, shewing the
fan wheels, and the pulley between them.
Fig. 3. is also a plan, but shewing the pulley at the end of the shaft, instead of
in the centre.
It will be observed in Fig. 1. that there are two fan-wheels A and A₁ keyed
upon the same shaft, or spindle B. and that they are set at different angles, by one
having the lead of the other, this causes the air when forced through the Y tube C.
to meet, and to unite into a continuous stream of air, that could not otherwise be
obtained, except by a considerable higher number of revolutions.
Fig. 2. being a plan of the same it will be clearly seen, how the fan-wheels A and A₁
revolving in their cases D and D, when driven by the pulley E between them,
forces the air through the Y tube C. In the plan Fig. 3. the pulley E. instead
of being in the centre is at the side, and the cases D. and D₁ are brought together,

page_text: but the action is precisely the same, ouly under certain circumstances it is more
convenient to have the pulley, or motive power, at the side instead of the centre,
as it would then be more readily got at when required to be attended to.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is―
First. Two, or more fan-wheels keyed upon the same shaft.
Second. Two, or more fans uniting their blast to reduce their speed.
Third. The cutting of one fan wheel in advance of another.
Fourth. The combination, and arrangements substantially as herein before
described.
