Toy bubble-blowing lawn mower

Abstract

A toy bubble-blowing lawn mower is disclosed having a wheel driven impeller coupled to a propeller for generating a stream of air. The impeller is also intermittently coupled to a bubble disk in either direction of rotation of the impeller for successively moving apertures in the disk covered by a bubble-forming liquid film into alignment with the stream of air.

What is claimed is: 
     
       1. A .[.toy.]. bubble-blowing .[.lawn mower.]. toy comprising in combination: a .[.lawn mower.]. body;   wheels rotatably mounted on said body to support said body for back and forth movement;   a propeller mounted for rotation on said body;   a housing on said body enclosing said propeller, said housing having a first opening through which a continuous stream of air is directed upon rotation of said propeller;   a reservoir formed in said body below the stream of air for receiving a bubble-forming liquid;   a bubble disk mounted on said body for rotation in a first plane normal to the stream of air with a portion of said disk immersed in the bubble-forming liquid in said reservoir, said disk having a plurality of radially and equi-angularly spaced apertures adapted to pass through the liquid in succession upon rotation of said bubble disk to form liquid films across said apertures;   an impeller mounted for rotation on said body, said impeller having a cam;   means coupling said impeller to said propeller for unidirectionally rotating said propeller .[.during rotation of said impeller in either direction.].;   means coupling at least one of said wheels to said impeller for rotating said impeller upon rotational movement of said wheel; and   means intermittently coupling said impeller cam to said bubble disk for advancing said bubble disk upon rotation of said impeller to successively position film covered apertures into alignment with the stream of air which blows the liquid films into bubbles.   
     
     
       2. The bubble-blowing .[.lawn mower.]. .Iadd.toy .Iaddend.according to claim 1 wherein said impeller has a gear, said propeller has a pinion, and said means coupling said impeller to said propeller comprises an arcuately moveable doublet gear having a pinion in constant meshing engagement with said impeller gear and a drive gear moveable into driving engagement with said propeller pinion upon rotational movement of said impeller in one direction, and out of driving engagement with said impeller gear upon rotational movement of said impeller in the opposite direction. 
     
     
       3. The bubble-blowing .[.lawn mower.]. .Iadd.toy .Iaddend.according to claim 2 wherein said wheel is secured to a shaft, and said means coupling said one wheel to said impeller comprises a pulley on said shaft, a pulley on said impeller, and a belt coupling said pulleys together. 
     
     
       4. The bubble-blowing .[.lawn mower.]. .Iadd.toy .Iaddend.according to claim 3 wherein said impeller is cylindrical and said impeller cam is V-shaped and mounted on the periphery of said impeller, said impeller further having an annular peripheral ring in alignment with the apex of said impeller cam, said ring having a notch in register with said impeller cam and of a width subtantially equal to the width of said impeller cam, said bubble disk has a shaft at right angles to said impeller and substantially in alignment with said impeller cam, and a plurality of radially and equi-angularly spaced, axially extending cam follower pins at one end of said shaft engageable in succession by said impeller cam upon rotation of said impeller in either direction of rotation. 
     
     
       5. The bubble-blowing .[.lawn mower.]. .Iadd.toy .Iaddend.according to claim 4 wherein said body has a spout connected to said reservoir through which a bubble-forming liquid can be poured into said reservoir, said body further having a second opening in alignment with said first opening and one of said apertures such that a bubble blown from said aperture is emitted through said second opening.
