Abstract

925,825. Dynamo-electric machines. L'USINE A IDEES. Oct. 18, 1961 [Oct. 24, 1960], No. 37436/61. Class 35. [Also in Groups XV and XXIV] An electric motor comprises an electromagnet the armature of which is arranged to vibrate and carries two or more pawls each engageable with a respective ratchet-wheel attached to a shaft, the teeth of one of the ratchet wheels being angularly displaced relative to those of the other ratchet wheels. Fig. 1 shows the chassis of a toy racing car driven by an electromagnet 2, which is energized by alternating current fed from a track via brushes (not shown) on the road wheels 12. The armature 6 is attached to a leaf spring 4, provided with a return spring 7, the vibrating system being resonant at twice the supply frequency. The right-hand end of the spring 4 is formed into four pawls 4b, 4c, 4d, 4e (Fig. 2) engageable with respective ratchetwheels 8b, 8c, 8d, 8e attached to the axle 9. Each ratchet-wheel 8 is angularly displaced, as shown in Fig. 3, by 1/n of the angle between two consecutive teeth, n being the number of ratchet-wheels. Ratchet-wheels 8b, 8c are moulded as a single member from plastics material. Lugs 9b, formed on the axle 9 engage slots such as 11d in the ratchet-wheels. A pin such as 10a is provided in each pair of ratchetwheels to engage a hole such as 11b in the other pair.
