A communication from ANTON REICHE, Lead Packing-case Factory, Dresden-
Plauen, Kingdom of Saxony, Empire of Germany.
1, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, 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 an arrangement or apparatus for the conversion of a
rotary motion created by the power of springs or the like into a reciprocating
motion; and is designed for use with toys, as e.g., toy carriages driven by spring-
power.
Its object is to throw a bevel-wheel on the driving-axle into gear with one of two
bevel wheels or pinions, set one on each side of it, so that the axle of the latter is
caused to rotate from left to right or from right to left.
As shown in the accompanying drawing, viz.: in
Figure 1 in cross section,
Figure 2 in plan as seen from above and in
Figure 3 in front elevation,
this arrangement consists of a longitudinal axis or shaft a around and to which
the coiled springs b are wound and secured. This shaft is located inside the box c
and carries on its forward end a ratchet-wheel d with which a pawl or catch e
engages, and also the handle f, by the rotation of which the springs bare wound
up, being secured at both ends to the rotating shaft a. The other end of a is
lodged in a horizontal slot of the cross-bar h so as to be enabled to slide from one
slide to the other, and carries also a cam plate g. Two rollers i are carried by the
cross-bar hon each side of the cam g.
As soon as the springs in their effort to unwind themselves set in rotation the
shaft a with the cam plate y and the bevel-wheel & immediately connected there-
with; the cam plate g comes in contact with the roller i and is sent by it, together
with the shaft a and bevel-wheel k over to the other side, so that the bevel-wheel k
which hitherto has been engaged with the small bevel-wheel on one side, is
disengaged therefrom and engages with the other small bevel-wheel on the other
side. By this transfer of the wheel and shaft froin the one side to the other, the
cain plate g is turned over on to the other roller i and is thereby again sent back so
that the bevel-wheel once more engages with the wheel on the opposite side. This
alternative play continues, so long as the shaft and cam plate are acted upon by the
power of the springs 6 as they continually seek to unwind. By this alternating
engagement of the bevel-wheel k with the bevel-pinions and on the axle m, this
latter is caused to rotate to the right or to the left, according to whether the
engagement takes place with the right or left hand bevel-wheel.
As here shown, this alternate rotary motion of the shaft m by means of the
toothed-wheel n and the pinion o (with which the latter engages) is transmitted
to the axle of o carrying the driving-wheels r of the toy. The carriage will
consequently run forwards a certain distance, then, during the change of movement,
stand for a moment still, and thereupon immediately run back again; and this
alternating play will be continued until the power of the springs is exhausted.
The use of this apparatus is not restricted to toy-carriages only, but may also
be applied to toys of any other form, in which a similar motion is required.

page_text: Having now particularly described and ascertained the nature of this said inven-
tion as communicated to me by my foreign correspondent and in what manner the
same is to be performed, I declare that what I claim is :-
An arrangement in toys for the conversion of a continuous rotary movement into
an alternating to-and-fro movement, in which a cam plate such as g mounted on the
end of a driving-shaft such as a carried so as to be capable of sliding to right or
left and connected to a bevel-wheel such as k is alternately acted on by two
stationary rollers such as i so that it passes over from one side to the other and
back again whereby an alternating engagement of the bevel-wheel k with bevel-
gear such as 1 on a shaft such as m is obtained and the latter is caused to rotate
first to the right and then to the left, substantially as described and illustrated in
the accompanying drawings.
