Abstract
Abstract An omni angle rotary table having a cam cylinder with an angularly disposed cam surface on its end, and a shaft which is axially and rotatably disposed with respect to the cam cylinder. A platform assembly is pivotally affixed to the end of the shaft and supports cam means which slidably engage with the cam surface on the cam cylinder, so that the platform assembly is caused to rotate and to pivot back and forth as the shaft and/or cam cylinder is rotated.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
86 words
An omni angle rotary table comprising, in combination: a shaft supported for rotation; a cam axially and rotatably disposed about said shaft and having one end thereof tapered to provide an angularly disposed cam surface; a platform assembly pivotally secured to the end of said shaft and having cam means slidably engaged with said cam surface on said cam; said platform assembly being caused to rotate and to tilt back and forth through an arc of excursion as said shaft is rotated relative to said cam.
Claim 2
Dependent Claim
86 words
An omni angle rotary table comprising, in combination: a shaft supported for rotation; a cam axially and rotatably disposed about said shaft and having one end thereof tapered to provide an angularly disposed cam surface; a platform assembly pivotally secured to the end of said shaft and having cam means slidably engaged with said cam surface on said cam; said platform assembly being caused to rotate and to tilt back and forth through an arc of excursion as said shaft is rotated relative to said cam.
Claim 3
Dependent Claim
28 words
The omni angle rotary table of claim 1, wherein both said shaft and said cam are rotated, whereby said platform assembly rotates and tilts in an oscillatory pattern.
Claim 4
Dependent Claim
31 words
The omni angle rotary table of chain 2, wherein said shaft and said cam are rotated at respective rates of speed such that several tilt cycles occur for each rotational cycle.
Claim 5
Dependent Claim
31 words
The omni angle rotary table of chain 2, wherein said shaft and said cam are rotated at respective rates of speed such that several tilt cycles occur for each rotational cycle.
Claim 6
Dependent Claim
25 words
The omni angle rotary table of claim 2, wherein said shaft and said cam are rotated so that the resulting oscillatory pattern is not reentrant.
Claim 7
Dependent Claim
35 words
The omni angle rotary table of claim 2, wherein said cam means comprises a pair of cam shoes laterally disposed on opposite sides of said shaft and arranged to slidably engage on said cam surface.
Claim 8
Dependent Claim
28 words
The omni angle rotary table of claim 2, wherein said cam is adjustable with respect to said platform assembly to compensate for any wear on said cam means.
Claim 9
Dependent Claim
46 words
The omni angle rotary table of claim 2, wherein said platform assembly comprises a tilting platform pivotally affixed to the end of said shaft and a platen adjustably secured to said tilting platform, whereby said platen can be initially adjusted at a pre-determined angle of tilt.
Claim 10
Dependent Claim
40 words
The omni angle rotary table of claim 2, wherein said cam surface is at an angle of approximately 30*, and said platform assembly tilts back and forth through an arc of excursion of approximately 60*, 30* either side of center.
Claim 11
Dependent Claim
26 words
The omni angle rotary table of claim 2, wherein said shaft and said cam both are adapted to be driven by means of rubber drive belts.
Claim 12
Dependent Claim
41 words
The omni angle rotary table of claim 2, wherein said platform assembly is affixed to said shaft by an axial pivot in line with the cam surfaces so as to provide a virtually balanced assembly, free of springs or other impairments.
Claim 13
Dependent Claim
31 words
The omni angle rotary table of claim 1, wherein said shaft and said cam can be locked together at any position and driven together for use as an adjustable rotary turntable.
