Method and Device for variable motion and applications using Interchangeable Heads

Abstract

A machine for automating manual labor has a motor portion, transmission portion, and a head portion which may all be interchanged with alternates for different applications. The machine is driven by an electric motor that can perform different motions and actions, one at a time or simultaneously, depending on the transmission and head portions. Two such motions are rotary and linear reciprocating motion. Applications include cleaning surfaces, cleaning vessels, mixer, blender, chopper, slicer, shredder, vibrator, massager, semi and fully automatic milk cream maker.

         7 . The device of  claim 1  wherein said head portion and transmission portion are adapted to perform functions selected from the group consisting of: sanding; buffing; polishing; scraping; foaming; vibrating; sanding; driving screws; ratcheting; sawing; cleaning vessels, cleaning surfaces, chopping objects, slicing objects, mixing objects, massaging, vibrating, whipping milk, whipping other liquids. 
     
     
         8 . An apparatus for achieving rotary and linear motion as claimed in  claim 1 , wherein said transmission mechanism comprises a partially complete spiral cam, concentric with the drive axle of said motor. 
     
     
         9 . An apparatus for achieving rotary and linear motion as claimed in  claim 1 , and wherein said head-piece comprises:
 a. an axle positioned longitudinally in said head-piece, having an end riding on said spiral and at the distal end of said axle is securely attached to said functionary portion; and   b. a biasing element for operatively pushing said axle back towards said motor, when said spiral turns passes the extreme forward position of said spiral, creating linear operational motion of said axle and said head-piece.   
     
     
         10 . An apparatus for achieving rotary and linear motion as claimed in  claim 1 , wherein the said head piece is operatively attached to comprise a bar across its diameter at the end closest to the drive axle of said motor whereby the said spiral catches on the said bar and causes the said head-piece to rotate as the said spiral rotates. 
     
     
         11 . An apparatus for making whipped liquid comprising:
 a. a motor portion;   b. transmission means;   c. a head-piece comprising attachment means allowing said head piece to attach to said motor portion and engage said transmission means, further comprising at least one disc of a predetermined thickness perforated with holes having a predetermined density and diameter;   d. an axle positioned longitudinally in said head-piece adapted to transfer linear motion from said transmission means to said disc;   e. a spring to push said axle and head-piece back towards said motor after said spiral has pushed said axle away from said motor;   
       whereby rotational motion of said motor is transformed to reciprocating linear motion, thereby forcing said perforated disc back and forth thereby whipping said liquid. 
     
     
         12 . The device of  claim 10  wherein said transmission means selected from the group consisting of a spiral cam.
