PROVISIONAL SPECIFICATION.
Improvements in Mechanical Toys.
I, AMY EMILY LUTTICKE Married Roseville, Gipsy Hill Upper Norwood London S.E.
do hereby declare the nature of this invention to be as follows:
My invention relates to the construction of mechanism for the production of toy
races such as bicycle, horse, walking etc. races and consists essentially of the
application of toothed discs (or their mechanical equivalent) not of circular shape but
so shaped and arranged that with continuous gearing different rates of speed are
alternately or successively obtained and by suitable contrivances are applied to various
toy figures or objects. The said discs or the like may be of any suitable shape such
as elliptical, square, conical etc. and any suitable motor may be used.

COMPLETE SPECIFICATION.
Improvements in Mechanical Toys.
I, AMY EMILY LUTTICKE of Roseville Gipsy Hill Upper Norwood in the County
of Surrey Gentlewoman 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 for its object to
obtain a race toy in which the speed of the competing figures or objects is varied thus
causing them to pass and repass one another upon the course as if engaged in an
actual race.
For this purpose I give motion to each figure or object through an independent set
of toothed discs or their mechanical equivalent of elliptical square, or other suitable
shape so arranged that they remain constantly in gear.
And in order that the said invention may be more clearly understood and readily
carried into effect I will proceed aided by the accompanying drawings more fully to
describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical transverse section of a race toy constructed according to my
invention.
Figure 2 is a plan thereof.
Figure 3 is an elevation taken at right angles to Figure 1.
Figure 4 is a plan representing a set of toothed discs of a modified form.
Figure 5 is a plan representing a set of gearing of a modified form and
Figure 6 is an elevation representing a set of gearing of a further modified form.
In the several figures like parts are indicated by similar letters of reference.
a represents a circular box or case within which the mechanism for conveying
motion to the figures or objects is located and a¹ represents the top thereof which
constitutes the race course.
b. c represent the figures or objects which are mounted upon the upturned outer
ends bc of horizontal arms 62 c² and the inner ends of these horizontal arms bare
respectively fixed upon the upper ends of vertical shafts b³ c³.
The shaft 6 is at its lower end mounted with capability of revolution in a footstep

page_text: bearing a fixed to the bottom of the case a and at its upper end passes through a hole
forming a bearing in the top a¹ of the case, and has fixed thereon a toothed disc b of
elliptical form whilst the shaft c³ is tubular and is mounted with capability of revolution
upon the, shaft 63 and has mounted thereon with capability of revolution a toothed
disc c of an elliptical form.
Upon the upper side of the toothed disc c is fixed a spring pawl c which engages
a ratchet wheel c fixed upon the hollow shaft e so that one of the figures or objects
may be moved over the course independently of the other in order to bring the two
figures or objects into alignment for a start.
The toothed discs b c respectively engage corresponding toothed discs d' d² fixed
upon a vertical shaft d at its lower end mounted in a footstep bearing a³ fixed to the
bottom of the case a and at its upper end mounted in a bearing a forined in the top a¹
of the case or box a.
**
Upon the vertical shaft d is also fixed a disc or wheel d³ upon the upper face of
which rests one end of a shafte which is at that end loosely mounted in a bearing a
formed in a vertical wall a* and at the other end passes through a bearing a³ formed
in the wall of the case a.
Upon the shaft e' is fixed a heavy fly wheel e which furnishes the necessary motive
power to propel the figures or objects and upon the outer end of the shaft e¹ is loosely
mounted a drum or reel 2 around which is coiled a length of cord e³ at its end
furnished with a pull or button e and upon the outer end of the drum or reel e² is
mounted a spring pawl e which engages a ratchet wheel e fixed upon the shaft e¹ so
that by drawing the cord e³ off the drum or reel the drum e² will through the
pawl e set the shaft e¹ and fly wheel e rapidly in motion.
In order to again wind the cord e³ upon the drum or reel e² I employ an india
rubber spring which is at one end fixed to a stud a carried by the case or box.a
and at the other end fixed to a small reel e fixed upon the end of the drum e² so that
as the cord e³ is pulled off the drum or reel e², the india rubber spring will be wound
upon the small reel e and upon the cord e being slackened the india rubber spring e
will rotate the drum and re-wind the cord e³ thereon.
The power stored in the momentum of the fly wheel e will be given off at the
shafte to the disc d³ and thus to the shaft d and toothed discs d' d' and through the
corresponding toothed discs bc to the figures or objects be which will continue to
move over the course until the fly wheel e again becomes stationary.
с
The elliptic toothed discs are mounted upon their shafts 6 3 at right angles to
each other and the toothed discs d' d' are similarly mounted upon their shaft d so as
to engage therewith, and it therefore follows that the shafts 63 and c³ will be rotated at
varying or differential speeds, and the figures or objects b c will thus be caused to
pass and repass one another and alternately take the lead during the progress of the
race.
In the example given at Figure 4 the toothed discs are formed square instead of
elliptical but the effect obtained by the employment thereof would be similar to that
bereinbefore described.
In the example given at Figure 5 a set of differential gearing is made up of
segments of toothed discs d' 6 of different diameters which gear with one another at
different positions in the revolution of their shafts d 3 as will be readily understood
and the segment d₁* of large diameter engaging the segment 6** of small diameter is
intended to give a sudden spurt to the corresponding figure.
In the example given at Figure 6 two conical wheels d' 6 are substituted for the
toothed discs, the wheel d¹ being provided with a diagonally disposed ring of teeth d¹*
to engage the wheel 6 at varying diameters and thus produce the desired variation of
speed.
I would here remark that I do not confine myself to the precise details herein
shown and described as it will be evident that a similar effect may be obtained by the
employment of mechanical equivalents for the toothed discs or wheels d' d b c and
that the details generally may be varied without departing from my invention.

page_text: 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 I
claim is :-
1. The improvements in mechanical toys substantially as herein shown and
described.
2. In a mechanical toy of the character herein described the interposition between
the motor and the moving figures of elliptic toothed discs or their equivalent for
producing differential speeds substantially as herein shown and described and for the
purpose stated.
