760,147. Toys including escapement mechanisms. TIGRETT ENTERPRISES, Inc. March 19, 1954 [April 30, 1953], No. 8088/54. Class 132(3). An escapement mechanism especially for use in toys utilizes a means capable of temporary adherence to a reaction surface as the timing device in the mechanism. In Fig. 1, arms 51 of a rotor 50 rotatable clockwise by a windable spring (not shown) are engageable with arms 25a, 26 of a pallet 22 provided with a suction cup which coacts with a roughened surface 27. In operation of the device, a rotor arm 51 engages pallet arm 26 and thus urges the suction cup into engagement with the surface 27. After sufficient air has leaked into the interior of the suction cup, the cup moves upwardly as a result of the pallet arm 25a being engaged by the next succeeding rotor arm 51 which then moves into engagement with the pallet arm 26 and the cycle of movements is repeated. Fig. 4 shows a toy fish in which the ends of a single-arm rotor 116 may extend through slots 144, 145, intermittent rotation of the rotor arm causing the toy to jump when resting on a surface and simulate a landed fish. In Fig. 6 (not shown), the arms of a six-armed rotor serve as " feet " of a toy bird which is propelled in a hopping manner. A " jumping bean" embodiment, Fig. 7 (not shown), has a single-arm rotor only one end of which is engageable with the pallet arms. In Fig. 8, intermittent engagement of a suction cup 190 and a surface 196 is caused when an arm 195 rotating clockwise engages in turn faces 193, 194, thus producing a reciprocating action of a yoke 191. In Figs. 12, 13 (not shown), a single arm pallet is provided with a cam surface which is engageable by the ends of the rotor arms. Alternative means to provide an imperfect seal of the suction cup and the coacting surface comprise leakage passages in the cup or the coacting surface and roughening the engaging surfaces of the cup and reaction surface. Pressure sensitive adhesive material may be used in place of a suction cup. |
