Abstract
Abstract A manual knitting machine with a needle bed in which needles are displaceably assembled, having a slide displaceable on the needle bed perpendicularly to the direction of motion of the needles, which slide, through a cam mechanism adapted to cooperate with the butts of the needles, is adapted to move the needles backwards and forwards to execute the knitting action, a needle selector mechanism, assembled on the slide, for moving specific needles out of their normal knitting position into a selecting position, and a control mechanism for arbitrarily operating the needle selector mechanism comprises an adjuster wheel assembled to rotate freely on the slide and having circumferentially distributed projections arranged, when the slide is displaced, to mesh with the needle butts in the manner of a gear, and a brake device which is arranged, when operated by the control mechanism, to stop the adjuster wheel so that the needle butts are displaced by the adjuster by a camming action of the wheel projections and the needles moved into their selector position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
195 words
A manual knitting machine comprising, in combination, a needle bed, a plurality of needles displaceably supported on said bed each having a butt, a slide displaceable on said needle bed perpendicularly to the direction of displacement of said needles, camming means defined on said slide cooperating with the butts of said needles to move said needles backwards and forwards to execute the knitting action, needle selector means mounted on said slide for moving specific needles out their normal position into a selecting position, control means mounted on said slide operating said needle selector means in a predetermined manner, said needle selector means comprising an adjuster wheel assembled to rotate freely on said slide, projections circumferentially distributed on said adjuster wheel and pivotal between camming and non-camming positions meshing with said needle butts whereby said wheel is rotated during movement of said slide, and braking means operable by said control means adapted to selectively stop and adjuster wheel rotation whenever a needle is to be moved to its selecting position so that said needle butts are displaced by said adjuster wheel by a camming action of said projections and said needles moved into their selecting position.
Claim 2
Dependent Claim
195 words
A manual knitting machine comprising, in combination, a needle bed, a plurality of needles displaceably supported on said bed each having a butt, a slide displaceable on said needle bed perpendicularly to the direction of displacement of said needles, camming means defined on said slide cooperating with the butts of said needles to move said needles backwards and forwards to execute the knitting action, needle selector means mounted on said slide for moving specific needles out their normal position into a selecting position, control means mounted on said slide operating said needle selector means in a predetermined manner, said needle selector means comprising an adjuster wheel assembled to rotate freely on said slide, projections circumferentially distributed on said adjuster wheel and pivotal between camming and non-camming positions meshing with said needle butts whereby said wheel is rotated during movement of said slide, and braking means operable by said control means adapted to selectively stop and adjuster wheel rotation whenever a needle is to be moved to its selecting position so that said needle butts are displaced by said adjuster wheel by a camming action of said projections and said needles moved into their selecting position.
Claim 3
Dependent Claim
75 words
A manual knitting machine is claimed in claim 1 in which said projections of said adjuster wheel comprise levers pivotally mounted on said adjuster wheel, a spring device biasing said levers into a center non-camming position and said levers being pivoted by the engaged needle butt into an operative camming position whereby said needles form an inclined plane to displace the engaged needle butt when said adjuster wheel is braked and said slide is displaced.
Claim 4
Dependent Claim
64 words
A manual knitting machine as claimed in claim 2, in which the axis of rotation in said adjuster wheel extends parallel to the direction of displacement of said needles and the pivot axis of each of said levers extends perpendicularly to the axis of rotation of said adjuster wheel, so that said levers project axially away from said adjuster wheel, between said needle butts.
Claim 5
Dependent Claim
17 words
A manual knitting machine as claimed in claim 1, in which said braking means includes an electromagnet.
Claim 6
Dependent Claim
30 words
In a manual knitting machine as claimed in claim 4, in which said electromagnet inCludes an armature engaging a groove defined in said adjuster wheel when said electromagnet is energized.
Claim 7
Dependent Claim
38 words
A manual knitting machine as claimed in claim 5 in which said control means includes programmed electric switching means mounted on said slide, said switching means being operable by the motion of said slide to actuate said electromagnet.
Claim 8
Dependent Claim
84 words
A manual knitting machine as claimed in claim 6 in which said switching means includes a switching wheel engaging the needle bed and driven by the slide motion and rotatably mounted on said slide, said switching wheel carrying a printed circuit arranged in a specific pattern, and a contact block mounted on said slide having a plurality of contacts sequentially engaging said printed circuit whereby the engagement of said contacts with the printed circuit generate signals for energizing said electromagnet in a predetermined sequence.
