PROVISIONAL SPECIFICATION.
An Improved Spring Motor for Working the Bellows of Organs and
for other purposes.
I, JOHN Mossor, of 39, Oxford Road, Altrincham, in the County of Chester,
Insurance Agent, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved spring motor for working the bellows
of organs and for other purposes, the object of my invention being to adapt an
arrangement of gearing actuated by a spring which can be wound up by hand
to store sufficient power to drive say a small organ or the like for a sufficient
length of time.
In constructing my improved driving mechanism I employ a coiled spring of
the necessary strength and secured one end to an axle carried in suitable bearings,
and the other end to a barrel, loose on the axle. The spring barrel is geared by.
a catch or pawl to a toothed wheel loose on the axle and geared by a train of
wheels to a crank shaft for working the bellows and also by a train of wheels to
a small fan regulated by a brake or to an equivalent check motion under the
control of the organist.
When the organist wishes to play the organ he charges the spring and then releases
the brake and allows the spring to turn the axle and the gearing to drive the bellows
and if the full power is not required the organist can apply the brake to the
governing mechanism and so check the speed of the gearing or stop it altogether.
Dated this 1st day of October 1898.

An Improved Spring Motor for Working the Bellows of Organs and
for other purposes.
I, JOHN Mossor, of 39, Oxford Road, Altrincham, in the County of Chester,
Insurance Agent, 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 relates to an improved spring motor for working the bellows
of organs and for other purposes, the object of my invention being to adapt an
arrangement of gearing actuated by a spring which can be wound up by hand

page_text: to store sufficient power to drive, say, a small organ or the like, for a sufficient
length of time.
In the accompanying two sheets of drawings-
Figure 1 is a side elevation, Fig. 2 a sectional plan of my improved spring
motor, and Fig. 3 a vertical section on the plane of the line A B, Fig. 2.
Fig. 4 is an elevation, Fig. 5 a plan, and Fig. 6 a detail view of an alternative
arrangement of check mechanism for regulating the speed of the gearing.
In the drawings a designates the frame of the motor ba barrel mounted on a
shaft c, to which it is connected by a powerful coiled spring, not shown, is a
ratchet wheel fixed on the shaft c and e is a pawl engaging the ratchet, fa band
fastened at one end to the spring barrel 6 upon which it is wound and at the
other end to a grooved fusee wheel mounted loosely upon a shaft h. The fusee
wheel is geared by a spring pawl i to a ratchet wheel formed with or secured to a
spur wheel loose on the shaft h on which is fixed a spur wheel in gear with a
pinion on a shaft m fitted with a handle n. By turning the handle n and
rotating the shaft m and pinion the latetr turns the wheel k, shaft h and fusee
wheel which is allowed to turn by the ratchet and pawl i thereby unwinding
the band from the spring barrel b and winding it upon the fusee wheel g and
so charging the spring.
The spur wheel j gears into a pinion o fixed on a shaft on which is also
fixed a spur wheel gearing into a pinion r on the crank shaft s the crank
of which is connected by a rod t to the organ bellows or other part to be
driven.
The spur wheel 7 also drives a pinion u fixed on a shaft von which is fixed
a spur wheel w driving a pinion a fixed on a shaft y on which is also fixed a skew
gear which drives a worm 2 on a shaft 3 which carries a fan 4. On the shaft y
is fixed a brake pulley 5 to which is applied when required a pivoted brake shoe 6
controlled by a hand or treadle lever 7 held normally in the position shown in
Fig. 3 by means of the spring 8.
When the organist wishes to play the organ he charges the spring by turning
the handlen as described and then releases the brake by depressing the brake
lever against the resistance of the spring thereby allowing the spring to turn
the shaft and the gearing to drive the bellows and the fan 4, and if the full
power is not required the organist can apply the brake to the governing mechanism
and so check the speed of the gearing or stop it altogether, and further by a
connection from the bellows the brake can be applied automatically whenever
the bellows have been inflated to any desired extent.
In the alternative arrangement of check motion illustrated by Figs. 4, 5 and 6
the fan 4 is dispensed with and instead I mount a governor 9 on a shaft 10 which
is driven by a bevel gear 11 from a bevel gear 12 fixed on the shaft v. The
sleeve of the governor is engaged by a clutch lever 13 fixed on a shaft 14 on which
is also fixed an arm 15 connected by an adjustable link 16 to the brake 6.
In this arrangement when the speed of the governor exceeds any predetermined
limit the balls rising draw up the governor sleeve, and by the connections raise
the link 16 and so apply the brake 6 to the brake pulley 5 until the speed is
reduced to the normal. The brake can also be applied at any time by means of
the hand or treadle lever 7.
In some cases the intermediate gearing might be dispensed with and the
pinion r on the crank shaft s be driven directly by the spur wheel k but in all cases
some suitable check motion would be necessary.
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 combination the spring barrel b, shaft c, ratchet d, pawl e, band f con-
nected at one end to the spring barrel b and at the other end to the
fusee 9 loose on shaft h, ratchet and pawl i gearing said fusee and shaft

page_text: together, means for winding up the spring, and gearing for driving the crank
shaft or equivalent shaft from the shaft h in conjunction with a suitable check
motion for governing the speed of the gearing all substantially as herein set
forth.
2. The general combination and arrangement of parts constituting an improved
spring. motor substantially as and for the purposes herein described with reference
to the accompanying drawings.
