Abstract
Abstract The eccentric locking device comprises an extension on the eccentric itself, a bushing placed about the aperture into which the eccentric is positioned and means for conjointly engaging the bushing and the extension of the eccentric to prevent relative movement therebetween. In a first embodiment a plurality of cavities is placed about the outer surface of the extension and the inner surface of the bushing. A pin is inserted conjointly in the cavities of both in order to prevent relative movement therebetween. In a further embodiment, the extension terminates in a transverse tab; a cap having a slot therein is then inserted atop the bushing''s outer surface and the tab is made to engage the slot to thereby prevent relative motion between the bushing and the eccentric.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
147 words
A locking member for an eccentric having an eccentric shaft positioned intermediate a first and second pilot shaft comprising: an extension coupled to said first pilot shaft; the outer surface of said extension having a plurality of first axially disposed cavities spaced apart from one another about said extension surface by a first angular displacement; a support member; an aperture in said support member proportioned to receive therein said first pilot shaft; a bushing positioned in said aperture about said first pilot shaft; a plurality of second axially disposed cavities about the inner surface of said bushing and spaced apart from one another by a second angular displacement; engaging means jointly engaging one of said first cavities and one of said second cavities to prevent relative movement between said bushing and eccentric; and a cap member proportioned to fit over and at least partially cover said bushing.
Claim 2
Dependent Claim
147 words
A locking member for an eccentric having an eccentric shaft positioned intermediate a first and second pilot shaft comprising: an extension coupled to said first pilot shaft; the outer surface of said extension having a plurality of first axially disposed cavities spaced apart from one another about said extension surface by a first angular displacement; a support member; an aperture in said support member proportioned to receive therein said first pilot shaft; a bushing positioned in said aperture about said first pilot shaft; a plurality of second axially disposed cavities about the inner surface of said bushing and spaced apart from one another by a second angular displacement; engaging means jointly engaging one of said first cavities and one of said second cavities to prevent relative movement between said bushing and eccentric; and a cap member proportioned to fit over and at least partially cover said bushing.
Claim 3
Dependent Claim
156 words
A locking member for an eccentric having an eccentric shaft positioned intermediate a first and second pilot shaft comprising: an extension coupled to said first pilot shaft; the outer surface of said extension having a plurality of first axially disposed cavities spaced apart from one another about said extension surface by a first angular displacement; a support member; an aperture in said support member proportioned to receive therein said first pilot shaft; a bushing positioned in said aperture about said first pilot shaft; a plurality of second axially disposed cavities about the inner surface of said bushing and spaced apart from one another by a second angular displacement; engaging means jointly engaging one of said first cavities and one of said second cavities to prevent relative movement Between said bushing and eccentric; and a cap member proportioned to fit over and at least partially cover said bushing; said cap member being coupled to said engaging means.
Claim 4
Dependent Claim
156 words
A locking member for an eccentric having an eccentric shaft positioned intermediate a first and second pilot shaft comprising: an extension coupled to said first pilot shaft; the outer surface of said extension having a plurality of first axially disposed cavities spaced apart from one another about said extension surface by a first angular displacement; a support member; an aperture in said support member proportioned to receive therein said first pilot shaft; a bushing positioned in said aperture about said first pilot shaft; a plurality of second axially disposed cavities about the inner surface of said bushing and spaced apart from one another by a second angular displacement; engaging means jointly engaging one of said first cavities and one of said second cavities to prevent relative movement Between said bushing and eccentric; and a cap member proportioned to fit over and at least partially cover said bushing; said cap member being coupled to said engaging means.
Claim 5
Dependent Claim
170 words
A locking member for an eccentric having an eccentric shaft positioned intermediate a first and second pilot shaft comprising: an extension coupled to said first pilot shaft; a plurality of first axially disposed cavities spaced apart from one another about said extension surface by a first annular displacement; a support member; an aperture in said support member proportioned to receive therein said first pilot shaft; a bushing positioned in said aperture about said first pilot shaft; knurling in the outer surface of said bushing to fixedly couple said bushing to said support member about said aperture; a plurality of second axially disposed cavities about the inner surface of said bushing and spaced apart from one another by a second angular displacement; engaging means jointly engaging one of said first cavities and one of said second cavities to prevent relative movement between said bushing and said eccentric; and a cap member proportioned to fit over and at least partially cover said bushing; said cap member being coupled to said engaging means.
Claim 6
Dependent Claim
170 words
A locking member for an eccentric having an eccentric shaft positioned intermediate a first and second pilot shaft comprising: an extension coupled to said first pilot shaft; a plurality of first axially disposed cavities spaced apart from one another about said extension surface by a first annular displacement; a support member; an aperture in said support member proportioned to receive therein said first pilot shaft; a bushing positioned in said aperture about said first pilot shaft; knurling in the outer surface of said bushing to fixedly couple said bushing to said support member about said aperture; a plurality of second axially disposed cavities about the inner surface of said bushing and spaced apart from one another by a second angular displacement; engaging means jointly engaging one of said first cavities and one of said second cavities to prevent relative movement between said bushing and said eccentric; and a cap member proportioned to fit over and at least partially cover said bushing; said cap member being coupled to said engaging means.
Claim 7
Dependent Claim
135 words
A locking member for an eccentric having an eccentric shaft positioned intermediate a first and second pilot shaft comprising: a transverse tab extension coupled to said first pilot shaft; a support member; an aperture in said support member proportioned to receive therein said first pilot shaft; a bushing positioned in said aperture about said first pilot shaft; knurling in the outer surface of said bushing to fixedly couple said bushing to said support member about said aperture; and cap means to couple said extension to said bushing said cap means proportioned to fit over said bushing and having a slot therein for receipt of said transverse tab extension whereby when said tab is positioned in said slot and said cap is on said bushing rotation of said eccentric with respect to said bushing is prevented.
Claim 8
Dependent Claim
135 words
A locking member for an eccentric having an eccentric shaft positioned intermediate a first and second pilot shaft comprising: a transverse tab extension coupled to said first pilot shaft; a support member; an aperture in said support member proportioned to receive therein said first pilot shaft; a bushing positioned in said aperture about said first pilot shaft; knurling in the outer surface of said bushing to fixedly couple said bushing to said support member about said aperture; and cap means to couple said extension to said bushing said cap means proportioned to fit over said bushing and having a slot therein for receipt of said transverse tab extension whereby when said tab is positioned in said slot and said cap is on said bushing rotation of said eccentric with respect to said bushing is prevented.
Claim 9
Dependent Claim
26 words
A locking member, as defined in claim 4, further comprising an indicator means on said cap to indicate the position at which said eccentric is locked.
