Abstract
Abstract Apparatus for reciprocating a yarn guide including a carriage mounted for reciprocating movement on a frame, a pinion wheel rotatably mounted on the carriage, a rack slidably mounted on the carriage meshing with the pinion wheel and having a follower sliding in an elongate track to control movement of the rack to rotate the pinion wheel, and a rack carrying a yarn guide and meshing with the pinion wheel such that rotation of the pinion wheel moves the yarn guide with adjustment of the angular orientation of the elongate track relative to the reciprocating path of the carriage controlling the distance of reciprocating travel of the yarn guide.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
167 words
Apparatus for reciprocating a yarn guide comprising a frame; a carriage supported on said frame and movable back and forth along a reciprocating path; pinion means rotatably mounted on said carriage; guide means mounted on said carriage; first rack means slidably received in said guide means and engaging said pinion means; a follower carried by said first rack means; elongate track means having a channel slidably receiving said follower; adjustment means pivotally mounting said track means on said frame to permit adjustment of said track means in parallel and oblique positions relative to said reciprocating path; and second rack means carrying the yarn guide engaging said pinion means whereby said follower slides along said track means to control rotation of said pinion means and movement of said second rack means and said yarn guide as said carriage is moved back and forth along said reciprocating path such that the distance of reciprocating travel of said yarn guide is controlled by the angular position of said track means.
Claim 2
Dependent Claim
167 words
Apparatus for reciprocating a yarn guide comprising a frame; a carriage supported on said frame and movable back and forth along a reciprocating path; pinion means rotatably mounted on said carriage; guide means mounted on said carriage; first rack means slidably received in said guide means and engaging said pinion means; a follower carried by said first rack means; elongate track means having a channel slidably receiving said follower; adjustment means pivotally mounting said track means on said frame to permit adjustment of said track means in parallel and oblique positions relative to said reciprocating path; and second rack means carrying the yarn guide engaging said pinion means whereby said follower slides along said track means to control rotation of said pinion means and movement of said second rack means and said yarn guide as said carriage is moved back and forth along said reciprocating path such that the distance of reciprocating travel of said yarn guide is controlled by the angular position of said track means.
Claim 3
Dependent Claim
35 words
The apparatus as recited in claim 1 wherein said pinion means includes a wheel having a toothed periphery, and said first and second rack means each have teeth engaging said peripheral teeth of said wheel.
Claim 4
Dependent Claim
17 words
The apparatus as recited in claim 1 wherein said first and second rack means are orthogonally aligned.
Claim 5
Dependent Claim
33 words
The apparatus as recited in claim 1 wherein said pinion means has teeth projecting therefrom and said first and second racks each have teeth directly meshing with said teeth of said pinion means.
Claim 6
Dependent Claim
32 words
The apparatus as recited in claim 1 and further comprising bias means disposed between said guide means and said first rack means for biasing said first rack means toward said pinion means.
Claim 7
Dependent Claim
72 words
The apparatus as recited in claim 5 wherein said guide means includes a sliding surface with a recess therein, said first rack means includes a rear surface Sliding on said sliding surface of said guide means, and said bias means includes a piston and a coiled spring mounted in compression in said recess between said recess and said piston to force said piston against said rear surface of said first rack means.
Claim 8
Dependent Claim
35 words
The apparatus as recited in claim 1 wherein said frame includes a pair of parallel rods slidably mounting said carriage, and a slide bar in parallel relation with said rods mounting said second rack means.
Claim 9
Dependent Claim
35 words
The apparatus as recited in claim 1 wherein said guide means and said first rack means are disposed transverse to said reciprocating path, and said second rack means is disposed parallel to said reciprocating path.
Claim 10
Dependent Claim
83 words
The apparatus as recited in claim 8 wherein said frame includes a slide bar disposed in parallel relation with said reciprocating path, said pinion means is a toothed wheel rotatably mounted on a shaft having an axis tranverse to said reciprocating path and said first rack means, said first rack means is a toothed member directly meshing with said toothed wheel, and said second rack means is a toothed member slidably carried by said slide bar and directly meshing with said toothed wheel.
Claim 11
Dependent Claim
24 words
The apparatus as recited in claim 9 and further comprising spring means biasing said first rack toothed member into engagement with said toothed wheel.
