Mechanical oscillator

An automatic mechanical oscillator comprising, in combination:

• a) a shaft,
• b) a follower body movable along said shaft,
• c) automatic cooperable bi-directional co-engaging drive means on said shaft and follower body, for effecting opposite oscillating movements of the body in response to continuous unidirectional turning of the shaft,
• d) said drive means having two separate and distinct automatically alternatingly-operable driving portions, one portion being operable to solely drive the follower body in one given axial direction in response to turning of the shaft through a predetermined one half revolution, and the other portion being operable solely to drive the follower body in an axial opposite direction in response to turning of the shaft through a succeeding one half revolution,
• e) the automatically alternatingly-operable driving portions of said drive means comprising a drive train having a pair of turnable rotary drive members each of which rotates in solely a given predetermined single direction during operation of the oscillator.

An automatic mechanical oscillator comprising, in combination:

• a) a shaft,
• b) a follower body movable along said shaft,
• c) a first cooperable drive means on both said shaft and said follower body, operable solely for effecting driving movement of the follower body in a first axial direction in response to unidirectional turning of the shaft through a predetermined one-half revolution in one direction, and
• d) a second cooperable drive means on both said shaft and said follower body, said second drive means being separate and distinct from said first drive means and being operable solely for effecting opposite-direction axial driving movement of the follower body in response to continued turning of the shaft in said one direction through a succeeding one half revolution,
• e) the first cooperable drive means comprising a turnable rotary drive member which rotates in solely a given predetermined single direction during operation of the oscillator, and
• f) the second cooperable drive means comprising a second turnable rotary drive member which also rotates in solely a given predetermined single direction during operation of the oscillator.

• e) the automatically alternately operable portions of said drive means comprising a drive train having a pair of turnable rotary drive members each of which rotates in solely a given predetermined single direction during operation of the oscillator,
• f) said rotary drive members comprising spindles which are turnably carried by the follower body,
• g) said shaft having a plurality of endless grooves in which portions of said spindles are received, and in which said spindle portions travel,
• h) said follower body having a bore through which the shaft passes, and
• i) said spindles projecting into said bore and being circumferentially oriented 180 degrees apart in said bore.
