Patent ID: 6902525

Claim:
A lightweight portable apparatus for producing simultaneous rotating and linearly reciprocating motion and transmitting such motion to a suitable self stimulation masturbation device, said apparatus comprising: a power transmission assembly including a drive shaft; connection means associated with the drive shaft adapted to enable rotatable connection of the drive shaft to an external rotating power source; and attachment means affixed to the distal end of said drive shaft and adapted to attach to and transmit motion from the drive shaft to a selected suitable self stimulation device; said power transmission assembly comprising, a linear actuation assembly operatively coupled to the drive shaft; and rotary energy transmission means associated with said drive shaft to transmit rotary energy from the drive shaft to the linear actuation assembly; said linear actuation assembly comprising; a transmission fork fixedly attached to said drive shaft; and a cammed shuttle connected to said transmission fork and adapted to receive rotational energy therefrom; a cam follower engage with said cammed shuttle to induce linear reciprocation of the shuttle within a confined space as it rotates.
