Abstract: 487,524. Toys. MULLER, H. Feb. 27, 1937, No. 5988. [Class 132 (iii)] A toy having spring or clockwork driving mechanism for travelling or other purposes has gearing provided in mechanical connection with said driving mechanism and with a blowon plate carried by said toy, alternate deflections of the plate produced by blowing or speaking operating said gearing to alternately start and stop the driving mechanism. Fig. 1 shows a blow-on plate 4 pivoted at 2, urged upwards by a spring 5 and having an arm 3 for extending into the path of projections 9, 9<1> on the wheel 6 which also carries on its other side projections 10, 11, 12 for extending into the path of the member 13 driven from the spring mechanism 1. The wheel 6 is weighted at 8 and successive blowings on the plate 4 cause alternate stopping and release of the member 13 to cause alternate stopping and release of the driving mechanism 1. The wheel 6 may have a thickened portion or may be spring loaded, or may have a clutch coupling or magnetic control instead of being weighted. In the construction shown in Fig. 7, the walls 11 of the driving mechanism frame are extended upwards to form a stop for the blow-on plate 4, which is urged upwards by a spring as in Fig. 1, or by a weighted lever 15. In the construction shown in Fig. 8, the rotating member 13 is controlled by a projection 17 on the toothed member 16 moved by a spring controlled hinged tooth 18 on the underside of the blowon plate 4. In the construction shown in Fig. 12 the member 13 is replaced by a spur wheel 22 driven from the spring mechanism 1 and engaging with a partially toothed weighted wheel 6<1> having projections 9, 9<1> for engaging the arm 3 on the blow-on plate 4. In the construction shown in Fig. 15, the member 13 has a projection which can be stopped by a tooth on the toothed wheel 26 connected to the ratchet wheel 27 moved by the spring controlled pawl 28 hinged to the underside of the blow-on plate 4. The wheel 26 is positioned by a spring 29 acting against the wheel 27. In the construction shown in Fig. 17, the spur wheel 22 driven from the spring mechanism 1 engages with the partially toothed weighted wheel 6<1> having three projections 9, 9<1>, 9<11> for engaging the arm 3 and having an open ring cam 34 with which can rotate the flag bearing lever 37 on the weighted arm 36 when the arm has been moved to the left. For this purpose a stronger blowing or a touch on the plate 4 is necessary to overcome the resistance of the spring 38 and cause the pivoted finger 40 to move the weighted arm 36 to the left. Return of the flag lever 37 is effected by the impulse which occurs when the toy is restarted by further blowing. In order to avoid jamming the projections 9, 9<1>, the projections 10, 11 and 12, the revolving member 13 and the arm 3 are preferably made angular and the revolving member 13 may be mounted in slots and held in the working position by a spring or by the driving action of a wheel. The wheel 6 or 6<1> may be mounted under the bonnet which may have a hinged folding cover by means of which access can be had to the interior of the toy through an opening in the bonnet. The revolving members 13 and 22 may have a high speed of rotation in toys of small dimensions so that only a slight blowing pressure is necessary. Friction drive may replace the toothed drive in Figs. 12 and 17, and further blow-on surfaces can be utilized for effecting other operations such as the discharge of a shot in tank toys. A sensitive arrangement is shown in Fig. 25 in which the projections 10 are nearer the centre of the wheel 6 than the projections 9, the arm 3a co-operating with the projections 9 has its rear end 15 supporting and resetting the blow-on plate 4, pivoted at 2a, and the revolving member 13 co-operating with the projections 10 is provided with a weight opposite its nose for balanced running.
