Improvements in Driving Mechanism for Toys.
I, LEONHARD KÄSER, of 3, Leonhardsgasse, Nuremberg, in the Empire of Germany,
Toy Manufacturer, 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 improvements in driving mechanism employed in con-
nection with mechanical toys, the object being to cause such toys when once wound
up or set in motion to proceed or move a certain distance or time in a forward
direction, then automatically to reverse the mechanism and travel or move with a
reverse motion, or backwards.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying drawings, in
which
Figs. 1 and 2 shew the improved mechanism in two positions.
According to this invention 1 is the driven axle operated by clockwork or spring in
any ordinary manner and fixed on such axle 1 is the ratchet wheel 13 the teeth of
which engage with the stop piece or catch 14 on the disc 2 as the clockwork or spring
is wound up or coiled by being turned in a reverse direction to that indicated by
the arrow in Fig. 1. When the apparatus is wound up the spring or clockwork
causes the axle I and ratchet 13 to rotate in the direction indicated by the arrow
(Fig. 1) and the ratchet 13 also carries round with it the dise 2 which is loose on the
axle and has a crank or eccentric pin 3 in its face, such pin engaging in one of the
two slots 6, 6 in a plate 4 pivoted at its upper end on a pin 5 and having its lower
edge in the form of a segmental rack 10 engaging with the pinion 8, wheels 12 and 9
to the axle 7 which rotates the wheels or mechanism of the toy. The plate 4 is also
provided with slots 11-11 through which the axle
passes.
When the disc 2 rotates through the uncoiling of the spring the pin 3 carries with
it the plate 4 and the rack 10 causing the pinion 8 and its train of wheels to rotate
in one direction. When the rack 10 has moved its full length the pin 3 will have
travelled from the top of and now be at the bottom of the slot 6 and the rotation of
the pin 3 continuing in the same direction it will now travel up the slot 11 and on
the opposite side of the axle 1 and this will cause the plate 4 to move in a reverse
direction and consequently reverse the motion of the mechanism of the toy. It will
be seen that the crank pin 3 imparts to the plate 4 a pendulum like motion and the
toy is continuously driven first in one direction then in a reverse direction.
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 general construction, arrangement, and combination of parts constituting
the improved mechanism as and for the purpose herein described and substantially
illustrated by the assomnanving drawings

page_text: (2) The disc 2 and pin 3 engaging with slots 6 in a toothed plate such as 4 and a
pinion 8 for communicating motion to the toy, all in combination as herein described
and substantially as illustrated by the accompanying drawings.
