Abstract
A toy welding apparatus includes a spin welding mechanism which is operative for welding thermoplastic articles together utilizing a rotating thermoplastic rod. The apparatus further includes a sparking mechanism for producing sparks during operation of the spin welding mechanism so that the operation of the welding apparatus realistically simulates that of an arc welding apparatus.
Claims8
A toy spin welding apparatus comprising:
- a thermoplastic rod having an end;
- rotating means for rotating said rod at a rate sufficient so that when said end is placed in contact with a joint between two articles made from thermoplastic materials which are compatible with said rod, the friction between said rod and said two articles is sufficient to melt said rod and to thereby weld said two articles together;
- and
- sparking means on said rotating means for producing sparks when said rotating means is actuated so as to cause the operation of said apparatus to simulate that of an arc welder.
1 more element
A toy spin welding apparatus comprising:
- spin welding means operable for welding first and second thermoplastic components and including a welding rod made of a thermoplastic material which is compatible with the thermoplastic materials of said first and second components and means for rotating said welding rod to weld said first and second components together with said welding rod;
- and
- sparking means for producing sparks adjacent said welding rod during rotation thereof so as to cause the operation of said apparatus to simulate that of an arc welding apparatus.
