I THOMAS WILLIAM BEVERLEY 224 Edmund Road, Sheffield in the County of York
Engineer do hereby declare the nature of my said invention for IMPROVEMENTS IN
BLOWING APPARATUS to be as follows:-
My invention has for its object to simplify the construction of blowing apparatus,
and to obtain the required blast without running the apparatus at a high speed.
It consists (speaking broadly) of a circle of bellows, (of the usual "long" construction
by preference) and made either in wood or metal driven or worked by means of
connecting rods from a central shaft, and forcing air into an annular chamber or
belt to which the bellows are attached.
In carrying out my invention according to one arrangement, which I describe as
an example, I make a suitable base by which the apparatus is to be secured to its
foundation, and upon this base I fix two standards to carry a horizontal shaft which is
provided with a fast and loose pulley or other means of receiving rotary motion.
Concentric with the beforementioned shaft. but at some distance from it, I fix an
annular air receiving chamber, or hollow belt, to the inside face of which I secure any
desired number of bellows hinged at one end in the usual manner of long shape
bellows, and communicating with the interior of the receiving chamber or hollow belt
by means of the usual clack valve.
"
Each bellows is opened and closed by means of one or more eccentric or crank rods
which receive their motion from one or more eccentrics or cranks upon the central
driving shaft, thus when the shaft revolves each bellows is worked alternately or in
rotation, forcing air into the air receiver from whence it is passed to the blast pipe or
other outlet.
The sides of the apparatus may be protected by wire gauze, or similar means, which
will admit air but will prevent dirt or small articles getting amongst the bellows.

page_text: I, THOMAS WILLIAM BEVERLEY 224, Edmund Road, Sheffield in the County of
York 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 :-
My invention has for its object to simplify the construction of mechanical blowing
Apparatus, and to obtain a sufficient strength of blast without running the Apparatus
at a high speed.
It consists (speaking broadly) of a circular arrangement of bellows, preferably of
the usual "long" construction, operated by means of connecting rods driven by a
central shaft and forcing air into an annular chamber to the internal face of which the
said bellows are attached.
And in order that my said invention may be clearly described and fully understood 1
annex a sheet of drawings in which similar letters of reference, indicate similar parts
in either of the figures.
Fig. 1, is a side elevation of a blowing apparatus constructed according to my
invention with part of the casing removed to show the interior.
Fig. 2, shows the construction of the crank shaft.
In carrying my invention into practice, in the construction of a blower such as is
illustrated, I build up a circular air chamber, consisting of six separate sections, or
receivers, marked A, (but this number is only given as an example) the inner faces
being made flat, and having an aperture B, to admit the air from the bellows.
Each
of the sections communicate where they are joined at C, so that there is a free passage
for the air round the air chamber to the outlet D, and the apparatus is supported on
legs E, or other suitable frame or base.
Upon the flat face of each section A, I fix a bellows F, having an inlet valve or
clack G, and an outlet valve G₁, the working of which will be readily understood.
The driving shaft is fixed in the centre of the apparatus, being supported by a
bracket H, on each side, (or by standards rising from a base plate as the case may be,)
it may be driven by means of a belt running upon a pulley in the usual manner or by
any other suitable means.
The bellows F, may be operated by a single or double set of connecting rods I,
attached to one or more cranks upon the driving shaft; in Fig. 2 I have shown a
double crank, K is the driving pulley, H, H, are the brackets which support the
shaft, L, L, are discs, M, M, are the crank pins upon which the connecting rods I are
placed, and N is a balance weight.
In this arrangement I place six of the connecting rods I upon each crank pin M,
and I attach one upon each crank to each bellows, as shown in Fig. 1, and in such a
manner, that when the shaft is revolved, the bellows are opened and closed in regular

page_text: rotation, no two bellows being in the same position at the same time, and thus I obtain
a continuous current of air, free from any objectionable pulsation.
The outside of the air sections I prefer to cast open, and close them up with sheet
metal O, the open sides where the bellows are seen may be covered by a protection
of wire gauze, to prevent dirt or small articles getting amongst the bellows.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is:-
1-In a blowing Apparatus, the combination of the bellows (such as F) with the
annular air receiver (such as A, A, A,) operated in the manner substantially as herein-
before described, and as illustrated.
2-A Blowing Apparatus constructed substantially as hereinbefore described and
illustrated.
