Improvements in Apparatus for Operating Organ Bellows, or for
other Pumping Operations.
I, EDWARD WILLIAM ANDERSON, Director of Easton Anderson & Company
Limited of 3 Whitehall Place in the County of London do hereby declare the
nature of my invention to be as follows:-
The object of my invention is to provide simple and economical apparatus
which occupies but small space, and is especially adapted for blowing organs by
means of electric motors but it is not limited thereto as it may be used for other
pumping purposes and be driven by other than electric motors from which an
ultimate rotary motion can be obtained.
According to my invention I drive by the motor employed a crank or wheel
with which is engaged one end of a rod whose other end is gimballed or universally
jointed so that as the crank or wheel rotates this rod describes a cone with its base
at the crank or wheel. To this rod an arm or arms is or are fixed which as the rod
moves as aforesaid will reciprocate and act on the pumping device which it or they
are to operate. There will generally be several of these arms acting on a corre-
sponding number of pumping devices such as feeders for instance for reservoirs of
organs.
I will describe an arrangement according to my invention as applied to organ
blowers, but I do not limit myself to the precise arrangements which I shall
describe.
A feeder or feeders (preferably not less than three)
or, are attached to the
bottom board of the reservoir in such a manner that the centres of gravity of their
bottom boards lie in a circle.
At the centre of this circle a pillar is fixed to the bottom board or otherwise
having a gimbal or other suitable universal bearing on its end, to which is attached
a stiff rod, forming an axis from which radiate a series of arms an arm of the
series extending under the centre of gravity of each feeder, and each arm carries
a small cup on the outer end in which the pivot shaped end of a short rod
attached to the bottom board of each feeder rests. If however the feeders are
to be made double acting the attachment of the rods of the feeders and arms
may be such as to give motion in both directions.
A wheel driven by the prime motor, by any convenient means, is placed in a
suitable frame with its axis vertical and directly under the centre of the feeder
circle. A hole is drilled in the wheel at a suitable distance from the centre into
which the end of the central rod depending from the gimbal bearing is placed.
On rotating this wheel the rod will be caused to describe a cone the apex of
which is in the centre of the gimbal, and as a result the ends of the radial arms
will reciprocate, thus actuating the feeders, and the action of each being successive
a very even current of air will be emitted.
The apparatus may be placed in any suitable position.
By the arrangement according to my invention very even delivery of the air or
matter pumped is obtained especially if three or more feeders or pumps be used.
An arrangement may be provided for varying the distance of the point of
engagement of the central rod to the wheel driven by the prime mover from the
centre of that wheel and so altering the stroke of all the feeders either auto-
matically (so as to act as a governor) or otherwise and so affording a means of
regulation of the quantity of air or matter pumped. In place of the arms a disc

page_text: may be used which may rotate with the central rod & act on runners on the ends of
the bellow rods or the like.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Operating Organ Bellows, or for
other Pumping Operations.
I, EDWARD WILLIAM ANDERSON Director of Easton Anderson & Company
Limited of 3 Whitehall Place in the County of London do hereby declare the
nature of my 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 my invention is to provide simple and economical apparatus which
occupies but small space, and is especially adapted for blowing orgaus by means of
electric motors but it is not limited thereto as it may be used for other pumping
purposes and be driven by other than electric motors from which an ultimate rotary
motion can be obtained.
According to my invention I drive by the motor employed a crank or wheel with
which is engaged one end of a rod whose other end is gimballed or universally
jointed or mounted so that as the crank or wheel rotates this rod describes a cone
with its base at the crank or wheel. To this rod an arm or arms is or are fixed
which as the rod moves as aforesaid will reciprocate and act on the pumping device
which it or they are to operate.
There will generally be several of these arms acting on a corresponding number
of pumping devices such as feeders for instance for reservoirs of organs.
will describe with reference to the accompanying drawings an arrangement
according to my invention as applied to organ blowers but I do not limit myself to
the precise arrangements which I describe and illustrate.
Figure 1 is a sectional elevation and Figure 2 is a sectional plan.
A feeder or feeders A (preferably not less than three but I bave shewn four in
the drawing) is or are attached to the bottom board of the reservoir in such a
manner that the centres. of gravity of their bottom boards lie in a circle.
At the centre of this circle a pillar or rod B is mounted it having a gimbal or a
ball and socket or other suitable universal bearing (b) at its lower end. To the
said pillar or rod B is attached a collar C with wings or projections to which are
secured a series of radial arms D an arm of the series extending under the centre
of gravity of each feeder, and each arm carries a small cup d on the outer end, in
which the pivot shaped end of a rod E attached to the bottom, board of each
feeder rests. If however the feeders are to be made double acting the attachment
of the rods of the feeders and arms may be such as to give motion in both directions.
A wheel F driven by any suitable prime notor and gearing (such as by a worm f
as shewn) is supported by a frame G with its axis vertical and directly under the
centre of the feeder circle. For small powers a pulley and strap may be employed
for driving. A hole f2 is provided in the wheel at a suitable distance from the
centre into which the end of the rod or pillar B is placed.
On rotating this wheel F the rod or pillars B will be caused to describe a cone,
the apex of which is in the centre of the gimbal, and, as a result, the ends of the
radial arms D will reciprocate thus actuating the feeders, and the action of each
being successive a very even current of air will be emitted.
H represents a guide frame for constraining one of the arms (and consequently
also the others) to move vertically to counteract any tendency of the arms to
rotate. If a gimbal bearing be used instead of a ball and socket bearing such
guide will of course not be necessary.

page_text: The apparatus may be placed in any suitable position as will be readily
understood, for instance the arrangement shewn may be inverted the gimbal being
at top and the driving wheel at bottom.
By the arrangements according to my invention very even delivery of the air or
matter pumped is obtained especially if three or more feeders or pumps be used
and as no reversal of stresses takes place with single acting feeders or pumps such
an arrangement is practically noiseless which is an important advantage for organ
blowing gear.
An arrangement may be provided for varying the distance of the point of
engagement of the rod or pillar B to the wheel driven by the prime mover from the
centre of that wheel and so altering the stroke of all the feeders or the like and so
affording a means of regulation of the quantity of air or matter pumped. I have
shewn for instance an extra hole at f³ nearer to the centre in which the end of the
rod or pillar B can be inserted when a shorter stroke is desired. The attachment
of the rod or pillar B to the wheel may be effected by a radial slider which can be
adjusted and fixed in position to vary the stroke. In place of the arms a disc may
be used which may rotate with the central rod and act on runners on the ends of
the bellows rods or the like.
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. Apparatus for operating organ feeders or bellows or the like consisting of
a rotatable crank or wheel actuating a rod or pillar gimballed or universally
jointed or mounted, and provided with an arm or with arms operating feeders or
pumping devices substantially as herein before described.
2. An apparatus for operating organ feeders or bellows or for other pumping
operations the said apparatus being constructed arranged and operating sub-
stantially as herein before described and shewn in the accompanying drawings.
