Improvements in Spring Motors.
I, WILLIAM MYRLIN LUTHER, residing at 1372 Michigan Street, Buffalo, in the
County of Erie, and State of New York, United States of America, Mason Contractor, 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:
This invention relates to spring motors, and the object thereof, is to provide an
improved device of this class which is designed to operate a fan and which may also
be employed for operating small machinery and for similar purposes.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part, in which:-
Fig. 1, is a side view of my improved motor;
Fig. 2, a section on the line 2, 2, thereof; and,
Fig. 3, a partial section on the line 3, 3, of Fig. 2.
In the drawing forming part of this specification, the separate parts of my
improvement are designated by the same numerals of reference in each of the
views, and in the practice of my invention, I provide a frame or casing which
consists of a front plate 5, and a back plate 6, and mounted centrally of said frame
or casing is a shaft 7, which projects through the front plate 5, and is provided on
the outer end thereof, with a gear wheel 8.
The shaft 7, is provided adjacent to the inner side of the back plate 6, with a pin
wheel 9, and above and below the shaft 7, at equal distances therefrom are shafts 10,
each of which is provided with a pin wheel 11, shown in full lines in Fig. 2, and in
dotted lines in Fig. 3, and each of the shafts 10, is also provided with a large gear
wheel 12, and these gear wheels 12, operate in connection with the pin wheel 9, on
the shaft 7.
I also provide four springs 13, which are mounted on shafts 14, which project
through the back of the casing as shown at 15, and which are adapted to be
wound up by keys connected with said projecting portions 15, of the shafts 14,
and the springs 13, which are wound on said shafts 14, are secured at one end
to transverse pins 16, and at the other end to the shafts 14, and each of said
shafts is provided with a large gear wheel 17, loosely mounted thereon and
connected to the spring 13, and the gear wheels 17, operate in connection with
the pin wheels 11, on the shafts 10, and as thus constructed it will be seen that
all of the springs 13, operate through the wheels 12, to turn the central shaft.
Secured to the outer side of the front plate 5, of the frame or casing by means
of rods 18, or in any desired manner is a vertical plate or support 19, and mounted
between said vertical plate or support 19, and the frame or casing, and below the
shaft 7, is a shaft 20, on which is mounted a large grooved wheel 21, and supported
by the frame or casing and the vertical plate or support 19, near the upper end
thereof, is a shaft 22, on which is mounted a small grooved wheel 23, and the
wheels 21, and 23, are geared in connection by a rope, cord or belt 24.
The outer end of the shaft 22, as shown in the drawing, is provided with a
blower 25, which may be of the usual or any preferred form, and which is designed

page_text: to operate as a fan, and secured to the inner side of the vertical plate or support 19,
is a keeper 26, through which passes a vertically movable screw threaded rod 27,
which is provided at its upper end with a knob or handle 28, and which passes through
another keeper 29, placed above the shaft 20, and the lower end of the rod 27, is
adapted to bear upon said shaft. 20, and operate as a brake.
The shaft 20, is provided with a pin wheel 30, in connection with which the gear
wheel 8, operates and by means of this device, the fan or blower 25, may be turned
with great speed, the speed and the length of time during which said fan or blower
is operated depending upon the spring drums 13, and the strength and the length of
the springs which form a part thereof.
My improved motor is absolutely noiseless when operating a fan and this is
the chief use for which I intend it, but it will also be apparent that the shaft 22,
may be used for transmitting power to small machinery such as a sewing machine,
and for other and similar purposes; and it will thus be seen that I accomplish the
object of my invention by means of a device which is simple in construction and
operation, and which is preferably adapted to accomplish the result for which it is
intended.
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. A spring motor provided with a large wheel mounted on a shaft which is
adapted to be operated by said motor, a small wheel mounted adjacent to said large
wheel, said small wheel and said large wheel being geared in connection by a belt or
similar device, and the shaft of the sinall wheel being adapted to be used as a power
shaft, substantially as shown and described.
2. A spring motor provided with a frame or casing and a central shaft which
passes therethrough, at one side thereof, said shaft being provided at its outer
end with a gear wheel, and being adapted to be operated by spring drums, and
connected gearing, and a shaft supported below said gear wheel, and adapted to
be operated thereby, a large wheel mounted on said shaft, another shaft provided
with a small wheel, said last-named shaft being adapted to be used as a power
shaft, and said small wheel and said large wheel being geared in connection,
substantially as shown and described.
3. A spring motor, mounted in a frame or casing provided with a central shaft
which passes therethrough at one side thereof, said shaft being provided at its outer
end with a gear wheel, and being adapted to be operated by a spring drum, and
connected gearing, and a shaft supported below said gear wheel, and adapted to be
operated thereby, a large wheel mounted on said shaft, another shaft provided with a
small wheel, said last-named shaft being adapted to be used as a power shaft, and
said small wheel and said large wheel being geared in connection by a belt or cord,
substantially as shown and described.
4. A spring motor constructed as herein described, and provided with a central
shaft, a gear wheel mounted thereon, a shaft mounted adjacent to the gear wheel,
and provided with a pin wheel in connection with which said gear wheel operates, a
large driving wheel mounted on said shaft on which the pin wheel is mounted, a
shaft adjacent to said large wheel, and provided with a small wheel, means for gearing
said large and small wheels in connection, and a fan or blower connected with the
shaft of the small wheel, substantially as shown and described.
