Abstract
Abstract A winder, such as a Model 959 take-up, manufactured by Leesona Corporation, Warwick, Rhode Island, has a rotary chuck mounted on a winder base and has chuck members resiliently urged into gripping engagement with a package core removably telescoped on the chuck. A lever is pivoted to the winder base and is operated in one direction by a fluid motor to release the chuck members from gripping engagement with the core. A brake member is pivotally connected with the lever in such a manner that operation of the motor in an opposite direction brakes the chuck and maintains the lever out of operating engagement with the chuck. The motor is controlled by a valve system which vents one side of the motor into the other side for positioning both the brake member and the lever out of engagement with the chuck.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
188 words
Apparatus for winding a strand to form a package comprising, a rotatable chuck for supporting a core on which said strand is wound, resilient means for urging said chuck to a gripping position to hold said core during rotation of the chuck, braking means operable to engage the chuck to stop rotation thereof, drive means operable to move said braking means to a first position to engage and brake said chuck to a stop and to a second position to release said braking means from engagement with said chuck, chuck releasing means movable in a first direction to engage said chuck to remove the chuck from said gripping position and movable in a second direction to disengage said chuck releasing means from said chuck, means on said drive means for moving said chuck releasing means in its first and second directions; and power means for operating said drive means to sequentially shift said braking means to said first position, move said chuck releasing means in said first direction while moving said braking means to said second position and thereafter shifting said chuck releasing means in said second direction.
Claim 2
Dependent Claim
188 words
Apparatus for winding a strand to form a package comprising, a rotatable chuck for supporting a core on which said strand is wound, resilient means for urging said chuck to a gripping position to hold said core during rotation of the chuck, braking means operable to engage the chuck to stop rotation thereof, drive means operable to move said braking means to a first position to engage and brake said chuck to a stop and to a second position to release said braking means from engagement with said chuck, chuck releasing means movable in a first direction to engage said chuck to remove the chuck from said gripping position and movable in a second direction to disengage said chuck releasing means from said chuck, means on said drive means for moving said chuck releasing means in its first and second directions; and power means for operating said drive means to sequentially shift said braking means to said first position, move said chuck releasing means in said first direction while moving said braking means to said second position and thereafter shifting said chuck releasing means in said second direction.
Claim 3
Dependent Claim
35 words
Apparatus as set forth in claim 1 wherein said chuck releasing means comprises a lever having a slot therein, and a pivot for pivoting said lever into engagement with said chuck to release said chuck.
Claim 4
Dependent Claim
34 words
Apparatus as set forth in claim 2 wherein said means on said drive means comprises a cam follower slideably engaging said slot to move said braking means to said first and said second positions.
Claim 5
Dependent Claim
68 words
Apparatus as set forth in claim 3 wherein said drive means comprises a cylinder, a piston slidable relative to said cylinder and connected to said braking means, said power means comprising a source of operating fluid connected to the cylinder to operate said piston to move said braking means to said first and said second positions and said chuck releasing means in said first and said second directions.
Claim 6
Dependent Claim
50 words
Apparatus as set forth in claim 4 including valve means for controlling passage of said fluid to said cylinder to operate said braking means to move said braking means to said first and said second positions and to move said chuck releasing means in said first and said second directions.
Claim 7
Dependent Claim
43 words
Apparatus as set forth in claim 5 wherein said slot includes a portion arranged to receive said cam follower, said cam follower when arranged in said portion acting to position said braking means in a position intermediate said first and said second positions.
