PROVISIONAL DI EUITIVATION.
Improvements in Motive Power for Toys.
1, WILLIAM HAMILTON HALL, of Moorside, Redhill in the County of Surrey
Gentleman, do hereby declare the nature of this invention to be as follows:-
My invention consists in the utilization of the power derivable from the
momentum of a weighted motor or fly wheel geared and adjusted in the following
manner, viz.:-
I make the spindle shaft or axle upon which the said motor wheel is fixed, in the
form of an endless screw and I adjust the same in such a position that the said endless
screw is in connection or geared with a toothed or serrated wheel, the said toothed
wheel being fixed upon any spindle shaft or axle required to be actuated by the
motive power.
I provide a reel whereon may be wound a string or other suitable
means in a suitable position for spinning the said motor_wheel. The said motor wheel
may be adjusted either vertically or horizontally. I construct or form the said
endless screw and the said toothed wheel respectively in manner following, viz. :-
(premising that the same respectively may be constructed or formed in any other
manner suitable or convenient to the purpose). Instead of constructing an endless
screw in the ordinary manner, i.e. by means of a worm coiled or formed around a
spindle or shaft so that the same has a solid centre consisting of the said spindle or
shaft, I construct the same so that the worm itself is sufficiently strong to stand alone
without any support in its centre being in fact a coiled spindle or shaft.
This construction may be effected either by making one continuous length of
spindle or shaft serve for the whole-a portion thereof in the position where the
worm is required being coiled, leaving straight portions at each end of and central
with the coiled part; or the same may be effected by means of a coiled spindle or
shaft welded or otherwise fixed at each end thereof to a separate_straight portion
central therewith or by other means suitable to the circumstances. To be operated by
and to operate an endless screw constructed as aforesaid, I form a toothed wheel by
means of simple serrations at the periphery forming teeth of a conical shape.
Dated this 4th day of September 1888.

COMPLETE SPECIFICATION.
Improvements in Motive Power for Toys.
I, WILLIAM HAMILTON HALL, of "The Retreat" Heath Park Leighton Bussard,
in the County of Bedford, Gentleman, 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 consists in the utilization of the power derivable from the
momentum of a weighted motor or fly wheel geared and adjusted in the following
manner, viz.
I make the spindle shaft or axle upon which the said motor wheel is fixed in the
form of an endless screw and I adjust the same in such a position that the said endless
screw is in connection or geared with a toothed or serrated wheel, the said toothed
wheel being fixed upon any spindle shaft or axle required to be actuated by the motive
power.
I provide a reel whereon may be wound a string or other suitable means in a
suitable position for spinning the said motor wheel, or the said motor wheel may

page_text: be spun by the pressure of the teeth of the toothed wheel upon the worm of the
said endless screw and the said motor wheel may be adjusted either vertically or
horizontally.
And in order that my invention may be well understood and carried into practice,
I will now proceed to describe the same with reference to the accompanying
drawings in which similar letters are used to indicato corresponding parts in both
figures.
Figure 1 is a sectional side elevation, and Figure 2 is a rear elevation of my
invention as applied to a vehicle.
Cis the heavy fly wheel or motor wheel rigidly fixed on the spindle D, and E is
the bobbin or reel also rigidly fixed on to the spindle D for actuating the same by
means of a string wound on the said bobbin or reel E or by equivalent means for
rapidly rotating the same. It is obvious however that momentum may be stored up
in the motor wheel C by rotating the shaft F carrying the toothed wheel B by simply
turning the wheel or wheels G fast thereon, or a small winch handle may be used if
desired, in which case each of the spindles F and D may be provided with a boss of
corresponding size so that the winch handle may be fitted over either of them
indiscriminately, and the storing up of the necessary momentum in the motor wheel C
effected from either, as desired.
Preferably I construct or form the endless screw A and the toothed wheel B
respectively in manner following, viz. :—
Instead of constructing an endless screw in the ordinary manner, i.e. by means of
a worm coiled or formed around a spindle or shaft so that the same has a solid centre
consisting of the said spindle or shaft, I construct the same so that the worm A itself
is sufficiently strong to stand alone without any support in its centre, being in fact
a coiled spindle or spiral shaft. This construction may be effected either by making
one continuous length of spindle or shaft serve for the whole, a portion thereof in the
position where the worm is required being coiled, leaving straight portions D at each
end of and central with the coiled part, or the same may be effected by means of a
coiled spindle or shaft .A welded or otherwise fixed at each end H thereof to a
separate straight portion D central therewith, or by other means suitable to the
circumstances.
To be operated by and to operate an endless screw constructed as aforesaid, I form
a toothed wheel B by means of simple serrations at the periphery forming teeth of a
conical shape.
If desired two bevel wheels may be substituted for the worm A and wheel B, or
other equivalent means adopted for transferring motion from one plane into a plane at
right angles.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is :-
In combination with a weighted fly wheel C on the shaft D, the worm A affixed to
or formed in one with the said shaft D, gearing into a worm wheel B fast on a
shaft or equivalent means for transferring motion between the two shafts D and F
at right angles to each other, substantially as and for the purpose hereinbefore set
forth and illustrated in the accompanying drawings.
