I WILLIAM ALLAN of 16 Amelia Terrace, Carlton Hill, Leeds, in the county
of York, Cabinet Maker, do hereby declare the nature of this Invention to be as
follows
My Engine is constructed as follows:-In suitable frame work I place a number
of shafts horizontal to each other, two of these shafts carry a number of spring boxes
in which are coiled springs, one end of each of the springs is attached to the side of
its spring box, its other end is secured to a loose boss or collar on the shaft, on the
spring box shafts are geared wheels from each spring collar gearing with suitable
gear wheels on the other horizontal shafts which are used for winding up the springs
and communicating motion to the top central power shaft, by suitable gearing the
winding wheels are made either fast or loose upon their shafts by inclines or pro-
jections upon discs upon a regulator shaft below the power shaft, the springs are so
arranged in their boxes that one or more of the springs are always being wound up.
Alternately a series of gear wheels on the various shafts impart motion to the fly
wheel shaft, a hand brake is also arranged by which the Engine can be stopped or
started. On each of the spring box shafts are a series of ratchets and ratchet wheels
for each spring for taking up purposes.
The action is as follows:-When made the Engine has the whole of its springs
(excepting one or two) more or less wound up, on taking off the brake the Engine is
put in motion when the larger number of the springs are employed in winding up one
or two of the other springs alternately as they require it, whilst the rest of the force
of the springs give motion to the Engine. A stationary motor so constructed can be
applied for driving all kinds of machinery, turret clocks, and all kinds of mechanism.
When applied as a portable Engine, reversing gear will be required and a double
acting brake and speeding gear will be required. The Engine or motor may be made
of any size or power.

page_text: I WILLIAM ALLAN of 16 Amelia Terrace, Carlton Hill, Leeds, in the county of
York, Cabinet Maker do hereby declare the nature of the said 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 construct a spring motor, consisting of an arrange- 5
ment of coiled steel springs arranged upon suitable shafts with gearing, so that on
taking off the brake the machine starts, and as any one spring running out or its
power becoming spent, it is rewound automatically by the other springs.

regulator shaft.
Figs. 8 and 9. are details of coiled spring.
Fig. 10. shews enlarged view of indicating apparatus.
Figs. 11 and 12. shew view of apparatus for utilizing the power of the springs as
they expand down to the spring box and carrier bracket.
My Engine is constructed as follows
-
A is the frame work, provided with necks and-bearings for a number of horizontal
shafts. B is the spring boss or power shaft, on which are a series of pinion wheels C,
having bosses D, within each of which is a ratchet wheel E, and a spring ratchet F,
for taking up purposes. G is a top carrier bracket which carries the spring boxes H
for the coiled springs H³, one end of each of the springs is attached to a swivelled

page_text: hanger H2, attached to the carrier bracket G, and the other end of each spring is
attached to each boss D of the pinion wheels on the power shaft. J is the winding up
shaft with its gear wheel J¹ gearing into one of the wheels C on the power shaft.
K is the winding up shaft having a series of gear wheels K' gearing into the wheels C
on the power shaft, at its end is a small pinion wheel K² gearing with the driving
wheel B', upon the spring or power shaft B. L is the regulator shaft upon which the
regulator gear wheel L' gearing with a small pinion L' attached to the intermediate
wheel L³ the fly wheel M being upon a stud M¹ fixed to the frame. M³ and M³ are
plate wheels, the pinion L² gearing into the pinion wheel L' upon the regulator
shaft; L gearing into the small pinion K which is loose on the rewinding up shaft K
for brake purposes and into the small pinion B2 upon the spring or power shaft B.
N are a series of regulators upon the shaft L one to each rewinding wheel K¹ upon
the shaft K, the sides of the bosses K' of these wheels are recessed so as to engage
with sliding clutches K³ these clutches having slots K₁, screws or pins K and
springs K, or other form of clutch may be used. The regulators N are arranged upon
their shaft Land revolve by gearing, and are so brought into contact with the clutches
as to put them into gear in turn and so keep the springs wound up as they run out.
P is a brake fork shaft for braking the shaft K when the Engine is required to be
stopped. P¹ is the brake fork, or other form of brake may be used. In order to
indicate how far the springs are spent or uncoiled I fix on each spring box a bracket R
carrying a dial S numbered according to the number of springs used, on the same
stud as the dial is a gear wheel S¹ gearing into a worm S³ the worm being attached
to a gear wheel S³ working into each spring boss wheel, by this means the indicator
will show if the springs are working equally, and regularly, and when not working
regularly any one spring can be separately wound up. To utilize the power of the
outer coils of the spring as it is uncoiling I employ a spring piston T pivotted to a
rack lever V, a rack wheel W is attached to each regulator N, carriers X for each
rack are attached to a shaft X¹ in any suitable position, in the carrier is an oval or
oblong groove Y for a runner V₁ to travel in, also on the other side of the rack is a
second runner V2 attached to a spring V³, so that on piston T being pushed by the
expansion of the outer coil, the rack V and runner VI travels down to the groove Y
to the bottom, the force of the spring V³ pushes it round the bottom of the groove,
and it then travels up the other side and round again operating the rack wheel W
when coming down the groove, and is out of gear when returning, so utilizing the
force given out by the expansion of the outer coils of springs H', when the inner coils
are partly expanded, thus the whole power of the springs are utilized. When the
spring boss or power shaft has revolved once the pinion on the power shaft will
revolve in proportion to the number of springs employed. The rewinding wheel
gearing into the spring boss wheels, which are smaller will make the spring boss
wheel revolve faster than the driving wheels, and so through the different trains of
wheels continuing the motion round to the first one again. Another trains of wheels
commencing with a small pinion wheel fixed on the spring shaft gears into a wheel
with pinion attached this pinion gearing into another wheel fixed on the regulator
shaft, makes the regulators revolve slower than the spring shaft and much slower
than the power shaft, the regulators are fixed at different points on their shaft, the
regulators working against the collars or clutches on the rewinding shaft putting them
out of and into gear as the springs are becoming spent, these spring bosses revolve
the contrary way to the driving wheel as the règulators pull them off and on,
and so on through the various regulators wound to the first one again; by
this means the Engine has the whole of its springs excepting a small portion more
or less wound up, on taking off the brake the Engine is put in motion, and the larger
number of the springs are employed in winding up the smaller proportions of springs
alternately as they run out or require rewinding, the rest of the force of the springs
is used to give motion to the Engine. A stationary motor constructed as above can
be applied for driving all kinds of mechanism. When applied as a portable Engine
reversing gear a double acting brake and speeding gear will be required.

page_text: Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I would have it understood that I
do not limit myself to the number or size of springs or to the arrangement of wheels
or other details of clutches and the like but what I do claim is :-
1. A spring motor consisting of a series of steel coiled springs attached to suitable
shafts and geared so as to alternately recharge each spring as it runs down for the
purposes shewn and described.
2. The use and employment of the regulators for alternately operating upon the
clutches for the purposes shewn and described.
3. Attaching the wheels upon the spring boss shaft so as to be loose one way and
fast the other, for the purposes shewn and described.
4. Indicating the position and action of the springs, as and for the purposes shewn
and described.
5. Utilizing the force given out by the expansion of the outer coils of the springs
as the inner coils are expanded, for the purposes shewn and described.
