Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
108 words
A feed dog sprocket link for a sprocket chain comprising a link having a pair of link plates connected by lengthwise spaced means maintaining said link plates transversely spaced, a feed dog member supported on said lengthwise sPaced means for lengthwise movement thereof, said feed dog member having spaced opposing surfaces, eccentric means disposed between and engaging said space opposing surfaces for selectively positioning said feed dog member lengthwise on said link, and means journaling said eccentric means on said link plates for rotation between said link plates, and means for angularly positioning said eccentric means to thereby selectively position said feed dog member lengthwise on said link.
Claim 2
Dependent Claim
108 words
A feed dog sprocket link for a sprocket chain comprising a link having a pair of link plates connected by lengthwise spaced means maintaining said link plates transversely spaced, a feed dog member supported on said lengthwise sPaced means for lengthwise movement thereof, said feed dog member having spaced opposing surfaces, eccentric means disposed between and engaging said space opposing surfaces for selectively positioning said feed dog member lengthwise on said link, and means journaling said eccentric means on said link plates for rotation between said link plates, and means for angularly positioning said eccentric means to thereby selectively position said feed dog member lengthwise on said link.
Claim 3
Dependent Claim
42 words
The invention as defined in claim 1 wherein said link plates each include projecting support means, said feed dog member being disposed for lengthwise movement between said projecting support means, and said eccentric means is rotatably supported on said projecting supporting means.
Claim 4
Dependent Claim
26 words
The invention as defined in claim 2 wherein said spaced surfaces of said feed dog member define a U-shaped slot, and engagement with said spaced surfaces.
Claim 5
Dependent Claim
40 words
The invention as defined in claim 3 wherein a set screw extends through said eccentric means into clamping engagement with the surface of said feed dog member for clamping said feed dog member against lengthwise movement relative to said link.
Claim 6
Dependent Claim
165 words
A feed dog sprocket link for a sprocket chain comprising a link having a pair of link plates connected by lengthwise spaced means for maintaining said link plates transversely spaced, said link plates having projecting support means, a feed dog member supported on said lengthwise spaced means for lengthwise movement thereon, said feed dog having transversely extending feed faces and a U-shaped slot disposed between said feed faces, eccentric means (turnably supported) on said projecting support means and disposed in said U-shaped slot (for selectively) and engaging the opposed surfaces of said slot, means journaling said eccentric means on said projecting support means for rotation between said support means, means for angularly positioning said feed dog member on said lengthwise spaced means, and threaded means threaded into and extending through said eccentric means and engaging the surface defining said slot to hold said eccentric means against turning and thereby hold said feed dog member fixed in a selective angular position on said lengthwise spaced means.
Claim 7
Dependent Claim
165 words
A feed dog sprocket link for a sprocket chain comprising a link having a pair of link plates connected by lengthwise spaced means for maintaining said link plates transversely spaced, said link plates having projecting support means, a feed dog member supported on said lengthwise spaced means for lengthwise movement thereon, said feed dog having transversely extending feed faces and a U-shaped slot disposed between said feed faces, eccentric means (turnably supported) on said projecting support means and disposed in said U-shaped slot (for selectively) and engaging the opposed surfaces of said slot, means journaling said eccentric means on said projecting support means for rotation between said support means, means for angularly positioning said feed dog member on said lengthwise spaced means, and threaded means threaded into and extending through said eccentric means and engaging the surface defining said slot to hold said eccentric means against turning and thereby hold said feed dog member fixed in a selective angular position on said lengthwise spaced means.
