Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
169 words
Apparatus for the formation of a threaded reserve on a thread-winding or takeup device while the thread advances towards such device, comprising: thread guide mans positioned in advance of the takeup device as viewed in respect of the direction of the advancing thread, said guide means having a lower surface substantially parallel to the longitudinal axis of the takeup device and extending across the winding or takeup range thereof, and a second curved surface merging with said lower surface and positioned in advance of a reserve range of said takeup device and switch means adjustably positioned by a pivot relatively to said guide means for maintaining the thread in the range of said second surface and adapted to release same from that range, the axis of the pivot by which said switch means is mounted being so located that said thread confining edge of said switch means is normally held by gravity in confining position and said lever may be pivoted to shift said edge away from said position.
Claim 2
Dependent Claim
169 words
Apparatus for the formation of a threaded reserve on a thread-winding or takeup device while the thread advances towards such device, comprising: thread guide mans positioned in advance of the takeup device as viewed in respect of the direction of the advancing thread, said guide means having a lower surface substantially parallel to the longitudinal axis of the takeup device and extending across the winding or takeup range thereof, and a second curved surface merging with said lower surface and positioned in advance of a reserve range of said takeup device and switch means adjustably positioned by a pivot relatively to said guide means for maintaining the thread in the range of said second surface and adapted to release same from that range, the axis of the pivot by which said switch means is mounted being so located that said thread confining edge of said switch means is normally held by gravity in confining position and said lever may be pivoted to shift said edge away from said position.
Claim 3
Dependent Claim
39 words
Apparatus according to claim 1, wherein said switch means has a second edge adapted to urge the thread into the range of said lower surface and the winding range of the takeup device upon release of the pivoting force.
Claim 4
Dependent Claim
16 words
Apparatus according to claim 1, wherein means are provided limiting the movement of said switch means.
Claim 5
Dependent Claim
163 words
Apparatus for the formation of a thread reserve on a thread-winding or takeup device while the thread advances towards such device comprising; thread guide means positioned in advance of the takeup device as viewed in respect of the direction of the advancing thread, said guide means having a lower surface substantially parallel to the longitudinal axis of the takeup device and extending across the winding or takeup range thereof, and a second surface merging with said lower surface and positioned in advance of a reserve range of said takeup device, and switch means pivotally mounted on said guide means and formed with an edge for maintaining the thread in the range of said second surface and adapted to release same from that range upon pivotal movement thereof in one direction, said switch means having a second edge for urging the thread into the range of the lower surface and the winding range of the takeup device upon pivotal movement in a second direction.
Claim 6
Dependent Claim
163 words
Apparatus for the formation of a thread reserve on a thread-winding or takeup device while the thread advances towards such device comprising; thread guide means positioned in advance of the takeup device as viewed in respect of the direction of the advancing thread, said guide means having a lower surface substantially parallel to the longitudinal axis of the takeup device and extending across the winding or takeup range thereof, and a second surface merging with said lower surface and positioned in advance of a reserve range of said takeup device, and switch means pivotally mounted on said guide means and formed with an edge for maintaining the thread in the range of said second surface and adapted to release same from that range upon pivotal movement thereof in one direction, said switch means having a second edge for urging the thread into the range of the lower surface and the winding range of the takeup device upon pivotal movement in a second direction.
