SIREN TOY WITH SPARII PRODUCING DEVICE Filed June 18, 1932 anventor Patented Feb. 28, 1933 PATENT OFFICE CARL ARNOLD, OF'NURMBERG, GERMANY SIREN TOY WITH SPARK PRODUCING DEVICE Application filed June 18, 1982, Serial No. 617,964, and in. Germany February 24, 1.982.

This invention relates to a toy with siren and spark producing device actuated by a rack drlving mechanlsm.

Siren toys for this purpose are already known which are operated by placing in the mouth and blowing air therein. These measures for producing soundswere not perfect from a hygienic point of-view. The spark beams could not be produced in conjunction with the siren sound. These objections are overcome by the toy hereinafter described.

An embodiment of the invention is illustrated by way of example in the accompanying drawing in which 2- Figure 1 shows the toy in side elevation partly in section.

Figure 2 shows the siren in top plan view, one half with the top plate removed, and, in section in the other half.

Figure 3 is a top plan view of the emery wheel fixing device.

Above a known rack driving mechanism a or the like, provided with returning spring,

' a casing, cap 0 or the like, is arranged,-whic has air-holes b, and is partly closed by a cover likewise having an air-hole d. In the interior of this casing a a second casing 'ihaving air-holes h is mounted on the driving mechanism shaft b. Any desired number of fan blades k of any suitable shape are fixed on the interior of the casing i. The blades is cause rotation .of the casing Flaps Z are likewise fixed on the driving mechanism shaft 9 and carry oscillatably mounted cerium stone levers m which are gyrated by the shaft g. The cerium stones carried by the levers m bear against an emery wheel a loosely mounted on the shaft 9. The emery wheel it must be loosely mounted in order not to impair the rapid movement of the cerium stone levers and of the blades of the siren, which is necessary for producing the sparks and the sounds. In order, during the gyrating movement of the oscillating levers, not to impart a too rapid rotary movement to the loosely mounted emery wheel owing to the friction produced between the wheel and the rotating shaft, which movement would prevent the pr duction of the sparks, a flap o is provided on the upper side of the siren and carries a strip of soft material such as rubber, cardboard or the like. This strip p bears againstthe emerydisc during the production of the sparks and only allows the wheel to rotate slowly. Intensive sparking is thus produced. Bridges fixed on the siren carry a disc 4 shaped as a head or the like'and provided with windows. The sparks produced pass through these windows or illuminate same in the event of coloured transparent panes being aflixed thereunder.

The toy operates in the following manner:

By exerting pressure on the rack of the driving mechanism the shaft 9 is rapidly rotated together with the casing 71 fixed thereon. Owing to the rotation air will be drawn through the cover hole at and propelled by the blades is towards the holes h in the rotary casing z. The air flows out from these holes through the holes I) of the stationary casing a. A siren like noise is thus produced which can be made louder or feebler by varying the pressure exerted on the rack. At the same time as the siren is sounded, the spark producing device Z, m, a connected to the driving 75 mechanism shaft is operated.

I claim 1. A siren comprising "in combination a rack driving mechanism having a returning spring, a stationary casing provided with so air-holes fixed on said mechanism, a cover on said casing, a driving shaft in said mechanism, a rotary casing provided with airholes fixed on said shaft and surrounded by said stationary casing, and blades on the interior of said. rotatable casing adapted to (lrawair into said rotatable casing and to expel same through the holes in said stationary casing to produce a siren like noise.

2. A siren toy as specified in claim 1, comprising in combination with the stationary siren casing and the shaft, oscillatable levers carrying cerium stones fixed on said shaft above said casing, an emery wheel loosely mounted on said shaft adapted to co-act with 95 said cerium stones to produce sparks during the rotation of said shaft and the production of the siren like noise.

3. A siren toy as specified in claim 1, comprising incombination with the stationary siren casing and the shaft oscillatable levers carryin cerium stones fixed on said shaft above sai casing, an emery' wheel loosely mounted on said shaft adapted to oo-act with said cerium stones to produce sparks during the rotation of said shaft and the production of the siren like noise, a flap on the upper side of said casing, and a strip of soft material carried by said flap adapted to bear against said emery wheel to brake said wheel and to ensure relative movement between said cerium stones and said wheel.

In testimony whereof I aflix my signature.

CARL ARNOLD.
