An Improved Electric and Tubular Pneumatic Action in Organs, and
in Means of Working the Combination Pistons of the same.
I, JAMES JEPSON BINNS, of Bramley, near Leeds, Organ Builder, 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 :-
DESCRIPTION OF DRAWINGS.
:-
Fig. 1, is an elevation of my improved electric action showing how the contact is
made and broken.
Figs. 2 and 3, show wind chest in section, and pneumatic tubes with electric
connections for making and breaking contact.
Fig. 4, shows improved means for operating the draw stops.
Fig. 5, is an enlarged detail of hydraulic motor for operating draw stops, by means
of combination pistons.
A is a small bellows to which is connected a pneumatic tube, from the coupling
boxes P, which are supplied with compressed air from wind chests C. D is a steel or
other suitable spring wire connector from the insulator E to the metallic conductor F,
also bearing upon the top of the bellows A, G are the electric wires. Upon a key N
being operated a puff of wind passes into the tube B, immediately raising the small
bellows A to the extent allowed by the regulator button R, which brings the spring
connector D in touch with the metal strip F and so the electric circuit is complete
and the puff spindle L is immediately raised by electricity; J are the coils, K is the
armature to which the puff spindle L is attached. M is a screw for regulating the
weight upon the armature. O is the wind chest connected to the main bellows and
described in the specification of Patent No. 1125688.
By this arrangement the action is instantaneous and the touch very delicate.
Figs. 4 and 5.
For operating the draw stops in lieu of bellows I employ a series of hydraulic motors
consisting of cylinders A with pistons B and four way valve C upon a suitable
spindle D, to each of the piston rods E are attached connecting rods, levers, or other
mechanical connections to make the different stop combinations required. A lever G
is connected from the valve spindle D to the small power bellows F which is supplied
with wind from tube H by the action of the combination piston at the key board.
The action is as follows:-
:―
By compressing any one of the combination pistons an air valve is opened admitting
air to the power bellows F, which operates the lever G attached to the valve spindle D
of the hydraulic cylinder A and feeds the said cylinder with water. On releasing the
combination piston the power bellows returns to its seat and admits water (by means
of the valve) reverse way bringing the piston back ready for again starting.
This arrangement can be placed in a very small compass and in any convenient
position thus saving the large space before required for the power bellows, the action
is also positive.
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. The use and employment of the electric action, worked by means of tubular
nnenmatic action such as shown and described.

page_text: 2. The spring connector D bearing upon the bellows A and in touch with the
metallic conductor F substantially as shown and described.
3. The application (in lieu of bellows) of.hydraulic motors such as shown and
described.
