PROVISIONAL SPECIFICATION.
Improvements in Mechanical Toys.
GEORGE FREDERICK LUTTICKE Merchant 50 Cromwell Road West Brighton County
of Sussex do hereby declare the nature of this invention to be as follows:-
In carrying out my invention I provide a shaft or axle of any suitable material,
on which are conveniently fixed at a convenient distance one from the other
2 suitable toothed wheels or their mechanical equivalent.
I further provide a wheel or its equivalent of suitable dimensions and having teeth.
on their equivalent, bevelled or otherwise, to the extent of part only of its circum-
ference such teeth or the like being arranged to alternately gear with the said 2 toothed
wheels or the like on the said shaft or axle. The latter may be arranged to drive,
directly or indirectly by any suitable gearing a wheel or wheels, for example of a
locomotive or any other vehicle or it may drive a boat by means of a screw propeller
paddle wheels or the like. It will be seen that the teeth or the like of the said
wheel or its equivalent gearing alternately with the 2 toothed wheels or the like on
the shaft or axle the mechanical effect will be the operating of the said shaft or axle
in contrary directions alternately, so that for example a vehicle, actuated by the
mechanism will be moved forward and backward alternately. Instead of the herein-
before described arrangement I may reverse the same by using a toothed wheel or the¸
like to be operated by a pair of partly toothed wheels or the like, arranged on a
common shaft or axle, gearing with the former alternately and thus producing
contrary mechanical action alternately.
I reserve to myself to use any kind of known motor including steam, a fly wheel,
spring, elastic, electricity etc. I further reserve to myself to apply the said mechanisms
for the purpose of moving any toy object alternately in contrary directions whether on
wheels or otherwise.
I also reserve to myself to adapt any suitable part of the mechanisms for other
mechanical effects in combination such for example as working a bellows in a
locomotive to blow a whistle etc.

Improvements in Mechanical Toys.
I, GEORGE FREDERICK LUTTICKE of 50 Cromwell Road, West Brighton Sussex
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 :-
My Invention relates to improvements in mechanical toys and has reference more
particularly to the employment of suitable actuating mechanism whereby the rotary
motion obtained from springs, steam, electricity or any other convenient form of
motive power causes the driving shaft or spindle of the vehicle or boat or other
part of the toy to be rotated alternately in opposite directions in the manner and for-
the
purpose hereinafter more particularly described.
In carrying out my Invention I provide a shaft or axle of any suitable material, on
which are conveniently fixed at a convenient distance one from the other two suitable
toothed wheels or their mechanical equivalent. I further provide a wheel or the
equivalent of suitable dimensions and having teeth or their equivalent, bevelled or
otherwise to the extent of part only of its circumference such teeth or the like being
arranged to alternately gear with the said two toothed wheels or the like on the said
shaft or axle.

page_text: The latter may be arranged to drive directly or indirectly by any suitable gearing
a wheel or wheels, for example of a locomotive or any other vehicle, or it may drive a
boat by means of a screw or paddlewheels or the like. It will be seen that the teeth
or the like of the said wheel or its equivalent gearing alternately with the two toothed
wheels or the like on the shaft or axle the mechanical effect will be that of operating
the said shaft or axle in contrary directions alternately, so that for example a vehicle,
actuated by the mechanism, will be moved forward and backward alternately. -
Instead however of the hereinbefore described arrangement, I may reverse the same
by using a toothed wheel or the like to be operated by a pair of partly toothed wheels
or the like arranged on a common shaft or axle gearing with the former alternately
and thus producing contrary mechanical action alternately.
I reserve to myself to use any kind of known motor, including steam, a fly wheel,
spring, an elastic; electricity etc. I further reserve to myself to apply the said
mechanism for the purpose of moving a toy object alternately in contrary directions
whether on wheels or otherwise. I also reserve to myself to adapt any suitable part
of the mechanism for other mechanical effects in combination such for example as
working bellows, in a locomotive to blow a whistle, and so forth.
In order that my Invention may be the better understood I have appended the
accompanying explanatory drawing. In Figure 1 I have shown the application of my
said Invention, for example, in its application to the propulsion of a toy locomotive,
but I do not limit myself to the particular form of vehicle or toy employed. Figures 2
to 4 inclusive illustrate elevation and plan views respectively of alternative forms of
the mechanism employed for producing the alternating rotary motion hereinbefore
described.
In the arrangement shown in elevation at Figure 1 and in plan to enlarged scale
at Figure 3, A is the shaft, spindle or axle carrying the driving wheels C, it working
within the framework or casing c. Keyed or otherwise conveniently fixed at a
suitable distance apart from each other are two pinions or toothed wheels a, a¹, or
their mechanical equivalents. I further provide a wheel or disc B, carried by its
spindle b which is supported within the framework c¹, having teeth-bevelled or
otherwise for a portion only of its circumference arranged to gear alternately with
the said pinions a, a', or their equivalents. In Figure I I have shown one form of
the driving motive power which I may employ for actuating the toothed wheel B. It
comprises a band or strip e of india rubber or the like attached, at one end, to the
spindle 6 of the wheel B and at the other end, at the front of the model vehicle, to a
spindle or projection adapted to the wheel e¹. The elastic band or strip e would be
twisted to obtain the necessary power by rotating the toothed wheel e¹, the untwisting
by the return of the wheel e¹ being prevented by the pawl f. In lieu of the
arrangement last described for producing the necessary motive power I might
employ a spring or any other suitable motor conveniently adapted in position,
whilst the toothed wheel B may be arranged in a horizontal or any other suitable
position.
The toothed wheel B may be arranged to drive the axle or shaft A direct as shown
in Figures 1 and 3, or indirectly as shown in Figure 2.. In the latter case the toothed
wheel B would engage with the pinions or toothed wheels a a¹ mounted on the
auxiliary shaft A¹, the driving shaft A being rotated at an increased speed relatively
to the shaft A¹ by the toothed wheel d mounted on the latter gearing with the
pinion d' secured to the driving axle A or by any other convenient means.
In Figure 4 I have shown a modified arrangement for producing the alternating
motion: above referred to, in which I reverse the method of driving before described.
In this case I employ only one pinion or toothed wheel a mounted on the driving
shaft A, said pinion or toothed wheel a together with the driving shaft or axle A
being rotated, alternately in opposite directions, by the wheels or discs B, B¹, which
are formed with teeth for a portion only of their circumference.
I do not restrict myself to the employment of any specific arrangement of driving
gear as same may be varied in practice without departing from the nature or
dispensing with the characteristic features of my said Invention.

page_text: Having now particularly described and ascertained the nature of my said Inven-
declare that what I
tion and in what manner the same is to be performed,
claim is :-
-
First The application to vehicles, boats or other devices of any description
employed as mechanical toys or as models, of a wheel or disc formed with teeth for a
portion only of its circumference said teeth engaging alternately with two pinions
mounted on a driving axle or shaft for the purpose of producing motion alternately in
opposite directions substantially as set forth.
Second-The application to mechanical' toys, such as those referred to in the
preceding claim, of two wheels or discs mounted on the same spindle or axle and
formed with teeth for a portion only of their circumference, the interrupted circum-
ferential teeth of said wheels engaging alternately with a pinion mounted on the
driving shaft or axle and rotating same alternately in contrary directions substan-
tially as set forth.
Third-In mechanical toys the employment of the means herein described or any
modification or equivalent thereof for producing rotary motion alternately in opposite
directions substantially as and for the purposes specified.
Fourth-The improvements in mechanical toys substantially as herein described
and shown from Figures 1 to 4 inclusive of the accompanying drawings.
