are being filled the brake keeps the last named pulley from revolving and the bevel
wheel on the sleeve remains stationary, consequently the stud wheel which gears
into it revolves round the shaft and causes the pulley on which it is mounted to

instead of the bevel wheels.

"
POWER FOR OPERATING THE BELLOWS OF ORGANS
"
Our invention is particularly applicable for the transmission of power to operate
organ bellows when gas engines are used, our object being to diminish or stop the
action of the bellows automatically when they become full.
We employ a shaft on which is a pulley driven by a belt from the motor and on
this shaft we fix a bevel wheel that gears into a bevel wheel that runs loose on a
stud or arm of a pulley loose on the said shaft which pulley drives the bellows:
this stud wheel gears into a bevel wheel fixed on a sleeve that runs loose on the
shaft and on this sleeve is fixed a brake pulley: a brake having a weighted lever
connected to the organ bellows is fitted near the brake pulley. While the bellows
are being filled the brake keeps the last named pulley from revolving and the bevel
wheel on the sleeve remains stationary consequently the stud wheel which gears
into it revolves round the shaft and causes the pulley on which it is mounted to
rotate and communicate motion to the bellows. When the bellows become full they
raise the brake lever and allow the brake pulley to revolve thus allowing the stud
pulley to turn without moving the pulley on which it is mounted and preventing
the transmission of power to the bellows.
The stud wheel pulley may be used as the brake pulley and the sleeve pulley
may be used to transmit the power, if desired, and friction wheels may be used
instead of the bevel wheels.
And in order that our Invention may be fully understood and readily carried
into effect we will describe the accompanying sheet of Drawings reference being
had to the figures and letters marked thereon.
Fig. 1 shows an elevation and Fig. 2 a plan of our improved apparatus for
regulating the transmission of power for operating the bellows of organs. Fig. 3
is an elevation of our improved apparatus showing another mode of carrying the
object of our Invention into effect. Fig. 4 is a section of the eccentric and gearing
shown in Figs. 1 and 2 and Figs. 5 and 6 are side views of two modifications of
our improved apparatus for regulating the transmission of power to the bellows of
organs and Fig. 7 is a plan of Fig. 6.
In Figs. 1. 2 and 4 a is the driving shaft on which is secured a pulley a¹ driven
by a band or belt from the gas engine or motor: on the shaft a is fixed a bevel
wheel b that gears into a bevel wheel c mounted and running loose on a stud d¹
of the eccentric d. The eccentric d is mounted and runs loose on the shaft a and
drives the organ bellows by means of the strap d and rod d³ connected to the
lever d which operates the bellows: an eccentric disc d³ to counterbalance the
weight of the eccentric d is secured to the shaft a. The stud wheel c gears into a
bevel wheel e cast with a long boss that runs loose on the shaft a and on this boss
is fixed a brake pulley f: a weighted brake lever f¹ is fitted near the brake
pulley fand connected by a cord or chain or in other convenient manner to one end
of a lever fa hinged at f³ and with a stud f' secured to and projecting from its
lower side. While the bellows are being filled the brake f¹ prevents the brake
pulley f from revolving and the bevel wheel e also remains stationary consequently
the stud wheel c which gears into it being driven by the bevel wheel b revolves
round the shaft a and causes the eccentric d to rotate and thus gives a reciprocating

page_text: motion to the eccentric strap d² connecting rod d³ and lever d' secured to the
bellows. When the bellows are nearly full they come in contact with the stud f*
and thus raise the lever f' which raises the brake lever f' and allows the brake
pulley to revolve thus allowing the stud wheel c to turn without moving the
eccentric d in which it is mounted and thereby preventing the transmission of power
to the bellows.
In Fig. 3. a is the driving shaft on which is secured a pulley a¹ driven by a band
or belt from the gas engine or motor: on the shaft a is fixed a bevel wheel b that
gears into a bevel wheel c mounted and running loose on a stud or arm of a
pulley & mounted and running loose on a shaft a. The stud wheel c gears into a
bevel wheel e cast with a long boss that runs loose on the shaft a and on this boss
is fixed a brake pulley f: a weighted brake lever f' is fitted near the brake pulley f
and connected by a cord or chain or in other convenient manner to one end of a
leverf hinged at f³ and with a stud f' secured to and projecting from its lower
side. A belt or band & transmits motion from the pulley d to a pulley g keyed or
secured to a crank shaft h and drives the organ bellows by means of the rod d³
connected to the lever d' which operates the bellows. While the bellows are being
filled the brake f¹ prevents the brake pulley f from revolving and the bevel wheel e
also remains stationary consequently the stud wheel c which gears into it being
driven by the bevel wheel b revolves round the shaft a and causes the pulley & to
rotate and thus communicates motion to the pulley g crank shaft h connecting
rod d³ and lever d' secured to the bellows.
When the bellows are nearly full they come in contact with the stud f" and
thus raise the lever f' which raises the brake lever f¹ and allows the brake
pulley to revolve thus allowing the stud wheel c to turn without moving the
pulley d in which it is mounted and thereby preventing the transmission of power
to the bellows.
The
In Fig. 5 a friction wheel or pulley a is keyed or secured to the driving shaft a¹
and drives by friction the wheel b keyed or secured to the shaft b' from which
motion is communicated to the organ bellows in any convenient manner.
shaft b' revolves in suitable bearings in an elbow lever c which is free to swing on
the fulcrum d. The lever c has a weight e suspended from its long arm and is
connected to the organ bellows by the cord or chain f as shown in Figs. 1, 2 and 3
or in any convenient manner. When the bellows are nearly full the long arm of
the lever c is raised and the friction wheel b is thus drawn out of contact with the
friction wheel a and the shaft b' ceases to revolve.
In Figs. 6 and 7. A friction wheel or pulley a is secured to the driving shaft a¹
and drives by friction the wheel b secured to the shaft b¹ carried in suitable
bearings. A spur pinion c is secured to the shaft b¹ and gears into a spur wheel d
carried on a stud d which forms the fulcrum of the lever e. Motion is commu-
nicated to the organ bellows from the spur wheel d in any convenient manner.
The elbow lever e is connected to the shaft b¹ and also to the organ bellows by the
cord or chain fas shown in Figs. 1, 2 and 3 or in any convenient manner and is
free to swing on the fulcrum d: a weight g is suspended from the long arm of the
lever e. When the bellows are nearly full the long arm of the lever e is raised and
the friction wheel b is thus drawn out of contact with the friction wheel a and the
spur wheels c and d cease to revolve.
Having stated the nature of our Invention and described the manner of
performing the same we would have it understood that we do not limit ourselves
to the precise details given as the same may be varied or modified without
departing from the main features of our Invention and→
We declare that we claim.
1. The improved apparatus for regulating the transmission of power for
operating the bellows of organs, substantially as herein shown and described.
2. The combination of the driving shaft a, bevel wheel b, stud wheel c,
eccentric d and connecting rod d³ with the bevel wheel e, brake pulley f and
brake lever f¹ in the manner and for the purposes herein shown and described.

hereunto set, our hands and seals this twenty eighth day of February One
thousand eight hundred and eighty three.
