PROVISIONAL SPECIFICATION.
An Improved Mechanical Movement for Toys.
HENRY PATTMAN TRUEMAN of 3 St. Georges Terrace Hockley Birmingham in the
county of Warwick Engineer and MAX EMANUEL of 83 Fore Street London in the
county of Middlesex merchant do hereby declare the nature of this invention to be as
follows:-
Our invention relates to that class of mechanical or moving toys in which a fly
wheel is used to store up power imparted, which said power is again given out, and so.
continues the action for some time after the source of power is withdrawn. Our
invention consists, in so arranging the driving, and the driven wheels, that while
storing the power, the driven wheel becomes the driver, and when giving out the
stored power their relative functions are reversed. In carrying our invention into
effect we employ a fly wheel with axle, this axle rests on a second wheel or pair of
wheels and is alternately driven and drives by contact. The weight of the fly wheel
is sufficient of itself to drive the second wheel, but when it is desired to impart rapid
motion to the fly wheel, by the rotation of the second wheel, we press the axle of the
fly wheel down upon the second wheel by means of a spring or other well known con-
trivance, which pressure is removed when it is required for the fly wheel to resume
the function of driver. In toy carriages, engines, and the like we arrange the
fly wheel axle in fixed bearings and the second wheel or pair of wheels are fixed
in bearings which allow of their axles being moved closer together. When such
carriage is pressed down on its roadway and moved forward by hand the road
wheels are pressed into contact with the fly wheel axle imparting motion to the
same, which is afterwards expended in moving the carriage a considerable distance.

COMPLETE SPECIFICATION.
An Improved Mechanical Movement for Toys.
We, HENRY PATTMAN TRUEMAN, of 3, St. Georges Terrace, Hockley, Birmingham,
in the county of Warwick, Engineer, and MAX EMANUEL, of 83 Fore Street, in
the city of London, Merchant, 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 :-
Our invention relates to that class of mechanical or moving toys in which a fly
wheel is used to store up power imparted, which said power is then expended to
drive the toy.
In toys of this class as heretofore constructed having a fly wheel axle resting on a
second pair of wheels the bearings of the fly wheel axle have been slotted in order
that the weight of the fly wheel may cause the axle thereof to rest upon and
drive the second pair of wheels. This fly wheel has been set in motion by a cord
wound upon and then rapidly unwound from its axle, the momentum of the fly
wheel then actuating the second wheels by the friction of the axle of the former
bearing on the periphery of the latter.
The object of our invention is to dispense with the use of cords or other additional
appliances for giving the necessary power to the fly wheel and for this purpose we 50
arrange the driving or fly wheel and the driven wheel or wheels that while storing
the power the driven wheel becomes the driver of the fly wheel and when giving out
the stored power the relative functions of the wheels are reversed.

page_text: The fly wheel axle rests on the second wheel or pair of wheels and is alternately
driven and drives by contact. The weight of the fly wheel is sufficient of itself to drive
the second wheel but when it is desired to impart rapid motion to the fly wheel we
rotate the second wheel and at the same time press the axle of the fly wheel down upon
the second wheel the pressure being removed when it is required for the fly wheel to
resume the function of driver. In toy carriages, engines and the like we find it
advantageous to arrange the fly wheel axle in fixed bearings and the axle of the
second wheel or pair of wheels in bearings which allow of its or their axle being
moved towards the other axle. When such carriage is pressed down on its roadway
and moved forward by hand the road wheels are pressed into contact with the fly
wheel axle, thereby imparting motion to the latter, the power so accumulated being
afterwards expended in moving the carriage for a considerable distance.
Or the required pressure may be produced by means of a pressure bar consisting of
a spring, lever, or sliding bolt which can be brought to bear by preference upon the
axle of the fly wheel which in this case is mounted in the loose bearing whilst the
second wheels are mounted in fixed bearings and are rotated by hand by means of a
crank. The pressure bar can however obviously be arranged to bear upon the axle of
the second wheel or wheels which would then have a loose bearing whilst that of the
fly_wheel would be fixed.
In order to enable our invention to be fully understood we will proceed to describe
how it can be carried into practice by reference to the accompanying drawing, in
which
Figure 1 is a sectional elevation illustrating our invention by way of example
applied to a toy carriage the required pressure of the fly wheel axle on the travelling
wheels being intended to be effected by pressing the latter upon their roadway.
Figure 2 is a transverse sectional elevation of figure 1.
Figures 3 and 4 are views similar to Figures 1 and 2 but shewing the wheels and
axles of the carriage arranged in combination with a pressure bar.
Similar letters in all the figures indicate similar parts.
We will first describe our invention by reference to Figures 1 and 2.
a is the fly wheel and b is the axle thereof. c, c are the fixed bearings in the
frame or sides of the carriage (part of which is shewn at d) in which the axle bis
mounted.
e, e are the second or travelling wheels and fis the axle of the same which we mount
in slotted or loose bearings g in the frame or sides d of the carriage so that the
axle can move nearer to or farther from the axle of the fly wheel.
The toy is operated by simply pressing the carriage d downwards upon its travelling
wheels e and at the same time moving the carriage forward for a short distance. The
pressure caused thereby of the fly wheel axle 6 upon the periphery of the travelling
wheels e whilst the latter are rotating will impart a rapid motion to the fly wheel a;
the pressure being removed the carriage will be caused to travel for a considerable
distance by the power accumulated in the fly wheel a being employed to drive the
travelling wheels e.
In the arrangement shown in Figures 3 and 4 h is the pressure bar hinged at i to
the frame d of the carriage and caused to bear upon the fly wheel axle 6 (mounted in
slotted bearings c) by manipulating the knob j in order to produce the required
pressure of the fly wheel axle b upon the peripheries of the travelling wheels e
(mounted in fixed bearings g) whilst the fly wheel is accumulating power. The
wheels e are rotated by means of a crank k.
Although we have only illustrated our invention as applied to toy carriages it is obvious
that it is equally applicable for actuating other toys such as those which exhibit figures
in motion.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A mechanical-tox movement in which o driving OR
A whool is emplowed the

page_text: axle of which bears upon and thereby actuates a wheel or wheels the said driving or
fly wheel and driven wheel or wheels being so arranged that while storing or accu-
mulating the power the driven wheel becomes the driver of the fly wheel and when
giving out the stored power the relative functions of the wheels are reversed
substantially as herein before described.
2. A mechanical-toy movement in which the bearings and axles of a set of wheels
are so arranged that the axles and wheels normally in contact can be pressed into
closer contact at will substantially as hereinbefore described.
3. The improved mechanical-toy movements herein before described with reference
to the accompanying drawing.
