Abstract
Abstract A device for ensuring the smooth shifting of a strand from a full reel to an empty reel in a strand winding machine including improvements in the snaggers provided on the wheels which are rotating with the two associated reels arranged parallel to each other. The snaggers are provided on each wheel and are supported by a shaft parallel to the central axis of revolution of the wheel such that the snaggers are rotatable about the shaft. The centroids of the snaggers are displaced from the pivot of the snagger itself, that is, positioned on that side of the pivot which is opposite from the pointed end of the snagger. Thus, the snagger can securely grip and hold the strand during rotation of the wheel and can release the strand when the wheel comes to rest.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
269 words
In a strand winding machine having two wheels and two reels respectively supported thereon, snaggers provided at the outer peripheral portion of each wheel rotatable with said reels and a mechanism for shifting the strand from a full reel to an empty reel, the improvement comprising: each of said wheels having the outer peripheral portion thereof shaped so as to form a part of a cone; shafts extending through the outer peripheral portion of each of said wheels so as to be parallel to the central axis of revolution of each of said wheels; a respective one of said snaggers provided at one end of each of said shafts so as to be pivotable on the outer peripheral portion of its associated wheel, each of said snaggers being so constructed as to include a pointed end for performance of a snagging operation and wherein the centroid of each snagger is positioned at a point displaced from the pivot of the respective snagger toward the side opposite the pointed end of said snagger; a plurality of pins, each of which is provided at at radial position corresponding to a radial portion of each of said reels mounted upon each of said wheels; and pivotable members having a portion thereof pivotable along the axial direction of said wheels, each of said members being joined at one end thereof to a respective shaft and extending in a radial direction, beyond said position of each of said pins, so as to be pivoted in accordance with the movement of said corresponding pin, said other end of said member being secured to said wheel.

Claim 3
Dependent Claim
14 words
The mechanism as set forth in claim 1, wherein said shafts are axially slidable.
Claim 4
Dependent Claim
15 words
The mechanism as set forth in claim 1, wherein said pivotable members are leaf springs.
