A Self Driving Spring Motor.
I, ALFRED WETTER, of Number 90, Henry Street, Newport, in the County of
Monmouth, Miller, do hereby declare the nature of this invention to be as
follows:-
This invention is a self acting motor the power being a strong coiled spring
enclosed entirely in an outer case. The mechanism is contained in a square box
frame of wrought or cast iron. A central vertical shaft carries the whole of the
gearing, which consists of various sized spur and bevil wheels substantially fixed
herein as described. The inner end of the coiled spring is fixed to the vertical
shaft and the other end to the outer case immediately over and fixed to this is
a bevil wheel which is driven by a bevil pinion on one end of a short horizontal
shaft, at the end of which is a bevil spur gearing into a stationary bevil wheel.
At the top end of the vertical shaft is a large diameter boss to which the last
mentioned wheel is attached, on the upper face of this wheel is an annular ring
or frame which carries a short horizontal shaft having a worm wheel gearing into
teeth on the large boss before mentioned, on the outer end of this shaft is a pulley
carrying a belt running on the pulley and a larger pulley with bevil teeth on its
inner side gearing with the bevil spur fixed to the under side of the large boss at
the top, and gearing with a large bevil spur at the bottom which is loose on the
main vertical shaft and connected with the shaft by means of a ratchet and pawl
arrangement underneath.
The large pulley referred to is carried on a shaft having its inner end fixed to
a double bracket through which the main vertical shaft passes.
I, ALFRED WETTER, of 90, Henry Street, Newport, in the County of Monmouth,
Miller, 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:-
-
The object of this invention is a spring motor, especially adapted for driving
light machinery.
Figs. 1, 2, and 3 of the accompanying drawing are respectively a side view and
two end views of a machine according to my invention. In all these figures the
same reference letters are used to indicate corresponding parts.
The invention is a self acting motor, the motive power being a strong coiled
spring enclosed entirely in an outer case A. The mechanism is contained in a

page_text: square box frame B of wrought or cast iron. A central vertical shaft C carries
the whole of the gearing which consists of various sized spur and bevel wheels sub-
stantially as herein described. The inner end of the coiled spring is fixed to the
vertical shaft C and the other end to the outer case A. Immediately over and
fixed to this case is a bevil wheel D) which is driven by a bevel pinion E on one
end of a short horizontal shaft on the other end of which is a bevel spur
F gear-
ing into a stationary bevel wheel G. The two wheels E and F are fixed on a
sleeve T which runs on the fixed horizontal shaft before mentioned. At the top
end of the vertical shaft C is a boss H'to which the bevel wheel G is attached.
the upper face of the wheel G is an annular ring or frame J which carries a short
horizontal shaft K having a worm wheel L gearing into teeth on the boss H before
mentioned. On the outer end of this shaft is a pinion wheel M gearing into a
large spur wheel N by means of an intermediate pinion O running on a wrought
iron shaft carried on a bracket cast on the frame J.
On
The large wheel N has bevel teeth on its inner side gearing with the bevil
spur G fixed to the underside of the boss H, at the top, and gearing with a large
bevil spur P at the bottom, which is loose on the main vertical shaft C, and con-
nected with the shaft by means of a ratchet and pawl arrangement Q underneath.
The large wheel N above referred to is carried on a shaft R having its inner end
fixed to a double bracket S through which the main vertical shaft C passes.
The manner in which the motor operates is as follows. The motive power, a
strong steel coiled spring, communicates a rotary motion to the spindle or shaft C,
the inner or centre end of the spring being attached to the shaft C. The bevel
wheel P being fixed on a sleeve the rotary motion is transmitted to this wheel
from the shaft C by means of a ratchet & pawl arrangement Q. The wheel P
gears into the bevel teeth of the wheel N which in turning travels round the peri-
phery of the fixed wheel G. The horizontal teeth of the wheel N gear into the
teeth of the wheel & so on to the wheel M, and the worm wheel L gears into
the worm teeth H which is fixed to the frame of the motor.
The rotary motion of the wheels D, E, & F travelling round the periphery of the
wheel G, causes the table J to revolve round the axis of the central shaft C.
The effect of the machine in motion is to wind up the spring as the motor
works.
"
The words "automatic" and "self-driving as applied to this invention, mean
that the motor is self driving but not perpetual, yet continuous so long as the
spring and other parts of the motor do not fail through breakage or until the
motor is stopped intentionally.
Power is taken from the vertical shaft C at any convenient point below the
wheel P.
The power from the motor is transmitted to any machinery by means of a pulley
on the shaft C carrying a belt to a pulley on the machine to be driven, or by
means of toothed wheel gearing, as might be most convenient.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed, I declare that what I
claim is: :-
(1st) A self-acting rotary motor, the driving power in which is a strong coiled
spring, the parts being all arranged & operating substantially as described with
reference to Figs. 1, 2, and 3.
(2nd) A rotary motor comprising a complete set of parts forming a self con-
tained & self acting motor which will impart driving power to tramway cars, road
cars, or sewing machines.
