Abstract
Abstract This winding machine includes a frame rotatably driven to wind filament onto a mandrel carried on the frame. To distribute the windings, the frame has an oscillated cradle pivoted thereon to support the mandrel. The cradle is oscillated by an indexing means which includes a shaft with a helically arranged row of pins projecting at right angles from the shaft. The shaft projects through a rotated indexing plate having one or more apertures which are aligned with succeeding pins to allow stepwise longitudinal movement of the shaft which is connected by linkage to the cradle to oscillate same and the mandrel carried thereby. The shaft is urged to move in either direction by an air motor controlled by limit switches actuated by the mandrel to reverse the direction of movement of the shaft.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
119 words
In a filament winding machine including a rotatable frame assembly having a mandrel pivoted therein for oscillating motion, the improvement comprising an indexing mechanism for imparting said oscillating motion to said mandrel, said indexing mechanism having incorporated therein a spindle having indexing pins extending therefrom at right angles thereto connected to said mandrel, a rotatable indexing plate having a circular central opening therein and a radially extending slot communicating with said opening, said spindle extending vertically through the opening in said indexing plate, whereby when said indexing pins are alternately aligned with the radially extending slot, said spindle will reciprocate to oscillate said mandrel and power means connected to the lower end of said spindle for the reciprocation thereof.
Claim 2
Dependent Claim
119 words
In a filament winding machine including a rotatable frame assembly having a mandrel pivoted therein for oscillating motion, the improvement comprising an indexing mechanism for imparting said oscillating motion to said mandrel, said indexing mechanism having incorporated therein a spindle having indexing pins extending therefrom at right angles thereto connected to said mandrel, a rotatable indexing plate having a circular central opening therein and a radially extending slot communicating with said opening, said spindle extending vertically through the opening in said indexing plate, whereby when said indexing pins are alternately aligned with the radially extending slot, said spindle will reciprocate to oscillate said mandrel and power means connected to the lower end of said spindle for the reciprocation thereof.
Claim 3
Dependent Claim
60 words
The improvement as in claim 1 wherein second power means is provided for rotating said frame assembly and said second power means is synchronized with the power means for reciprocating said spindle so that said filament winding machine will wind a filament on said mandrel longitudinally thereof so that the windings thereon are in longitudinal contactual relation to each other.
Claim 4
Dependent Claim
31 words
The improvement as in claim 1 wherein a switch actuating stud is mounted on said mandrel to actuate electrical switches upon contact therewith to reverse the oscillating motion of said mandrel.
Claim 5
Dependent Claim
24 words
The improvement as in claim 1 wherein a cradle is pivotally connected to said mandrel and said spindle is pivotally connected to said cradle.
Claim 6
Dependent Claim
37 words
The improvement as in claim 1 wherein said indexing plate has a row of peripheral gear teeth thereon and a fixed gear is mounted for coaction with said gear teeth for the rotation of said indexing plate.
Claim 7
Dependent Claim
40 words
The improvement as in claim 1 wherein said indexing plate is a pulley, a fixed pulley is mounted adjacent said indexing plate and a belt engages said indexing plate and said fixed pulley for the rotation of said indexing plate.
Claim 8
Dependent Claim
69 words
The improvement as in claim 5 wherein a first tubular standard is mounted on said frame assembly, said spindle extends through said standard and said indexing plate is mounted for rotation on the upper end of said standard. 8, The improvement as in claim 1 wherein the index pins are arranged on said spindle in staggered helical relation to the longitudinal axis of said spindle and to each other.
Claim 9
Dependent Claim
44 words
The improvement as in claim 1 wherein said mandrel comprises outer plates having seats therein adjacent the outer edges thereof and an intermediate contoured plate is positioned between said outer plates with the longitudinal edges thereof positioned in the seats in said outer plates.
Claim 10
Dependent Claim
57 words
The improvement as in claim 7 wherein a second tubular standard is mounted on said frame assembly adjacent said first tubular standard and said fixed gear is mounted on said second standard and an air supply to said power means for reciprocating said spindle is directed through said second standard to be connected to said power means.
