Abstract
Abstract A bobbin frame on upward twisting machines having a machine frame and also having conveyor means arranged adjacent to the machine for receiving filled bobbins. The bobbin frame is pivotally supported by pivot means on the machine frame and comprises bobbin-sleeve-receiving means for substantially coaxially therewith supporting a bobbin sleeve held between two supporting arms and adapted to be fitted with a bobbin rotatable as thread is wound up or wound off therefrom and also includes means for selectively increasing and decreasing the distance between said pivot means and said bobbin-sleeve-receiving means to thereby selectively increase the pivoting radius of said bobbin frame for depositing the bobbin itself on the conveyor means.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
160 words
A bobbin-holding apparatus for an upward twisting machine having a machine frame and also having conveyor means arranged adjacent said machine, said apparatus including a bobbin frame having lever means pivoted at one end about an axis on the machine frame and a bobbin-supporting member movably connected to the free end of said lever means and having bobbin-receiving means for holding a bobbin, said bobbin-supporting member being movable relative to said lever means to vary the distance between said bobbin-receiving means and said axis, releasable latch means to hold said lever means and bobbin-supporting member against relative movement as said bobbin frame pivots about said axis during winding of said bobbin, said bobbin-supporting member being movable relative to said lever means when said latch means is released so that said bobbin-receiving means can be moved relative to said lever means and toward said conveyor to place said bobbin on said conveyor when said bobbin is freed from said receiving means.
Claim 2
Dependent Claim
160 words
A bobbin-holding apparatus for an upward twisting machine having a machine frame and also having conveyor means arranged adjacent said machine, said apparatus including a bobbin frame having lever means pivoted at one end about an axis on the machine frame and a bobbin-supporting member movably connected to the free end of said lever means and having bobbin-receiving means for holding a bobbin, said bobbin-supporting member being movable relative to said lever means to vary the distance between said bobbin-receiving means and said axis, releasable latch means to hold said lever means and bobbin-supporting member against relative movement as said bobbin frame pivots about said axis during winding of said bobbin, said bobbin-supporting member being movable relative to said lever means when said latch means is released so that said bobbin-receiving means can be moved relative to said lever means and toward said conveyor to place said bobbin on said conveyor when said bobbin is freed from said receiving means.
Claim 3
Dependent Claim
139 words
A bobbin-holding apparatus for an upward twisting machine having a machine frame and also having conveyor means arranged adjacent said machine, said apparatus including a bobbin frame having a lever means pivoted at one end about a first axis on the machine frame, a bobbin-supporting member pivotally connected to the free end of said lever means about a second axis parallel to the first axis and having bobbin-receiving means for holding a bobbin, releasable means to hold said lever means and bobbin-supporting member against relative pivotal movement about said second axis as said bobbin frame pivots about said first axis during winding of said bobbin, said bobbin-supporting member being movable about said axes when said releasable means is actuated so that a bobbin on said supporting member can move to said conveyor for placing said bobbin on said conveyor.
Claim 4
Dependent Claim
139 words
A bobbin-holding apparatus for an upward twisting machine having a machine frame and also having conveyor means arranged adjacent said machine, said apparatus including a bobbin frame having a lever means pivoted at one end about a first axis on the machine frame, a bobbin-supporting member pivotally connected to the free end of said lever means about a second axis parallel to the first axis and having bobbin-receiving means for holding a bobbin, releasable means to hold said lever means and bobbin-supporting member against relative pivotal movement about said second axis as said bobbin frame pivots about said first axis during winding of said bobbin, said bobbin-supporting member being movable about said axes when said releasable means is actuated so that a bobbin on said supporting member can move to said conveyor for placing said bobbin on said conveyor.
Claim 5
Dependent Claim
120 words
A bobbin-holding apparatus according to claim 2, in which said bobbin frame comprises: first lever means having one end portion thereof pivotally supported by said pivot means about said first axis, second lever means forming said bobbin-supporting member having one end portion carrying said bobbin-receiving means, joint means pivotally interconnecting the other end portions of said first and second lever means for movement about said second axis, and control means forming said releasable means associated with said first and second lever means and operable to selectively interlock said first and second lever means at an angular position with regard to each other and to release said interlock for angular movement of said first and second lever means with each other.
Claim 6
Dependent Claim
30 words
A bobbin holding apparatus according to claim 3, in which said second lever means comprises a U-shaped member with the free ends of said legs thereof carrying said bobbin-sleeve-receiving means.
Claim 7
Dependent Claim
59 words
A bobbin holding apparatus according to claim 3, in which said control means comprises manually operable latching means associated with one of said lever means and also includes recess means associated with the other one of said lever means for selectively receiving said latching means for selectively arresting said first and second lever means with regard to each other.
Claim 8
Dependent Claim
134 words
A bobbin holding apparatus according to claim 3, in which said control means comprises a parallelogram linkage means in which said first and second lever means form parts of the said parallelogram linkage means and which additionally comprises two interlinked members respectively substantially parallel to said first and second lever means and pivotally connected thereto, to form other parts of said parallelogram linkage means and being operable to pivot said first and second lever means relative to each other and locking means respectively connected to one of said members and said first lever means and operable selectively to interlock one of said members and said first lever means for arresting said parallelogram linkage means and to unlock said first lever means from said one member to thereby permit operation of said parallelogram linkage means.
Claim 9
Dependent Claim
49 words
A bobbin holding apparatus according to claim 1, with spindles arranged on both sides of the longitudinal central plane of the machine, in which said conveyor means is endless and located in said central plane of the machine and common to both of said machine sides sharing the same.
Claim 10
Dependent Claim
149 words
A bobbin holding apparatus according to claim 4, in which at least one of said legs has that portion Thereof which carries bobbin-sleeve-receiving means pivotally connected to a portion of said second lever means to permit release of a bobbin from the bobbin-receiving means supporting such bobbin, said pivotally connected leg portion being provided with an extension extending in the direction away from said bobbin-receiving means, and means connected to said first lever means and comprising an inclined surface for sliding engagement with said extension so as to move said leg portion and thereby said bobbin-receiving means away from the other leg in response to the pivoting of said second lever means about said pivot means to a position in which said bobbin-receiving means, and thus a bobbin held thereby is above said conveyor means to thereby release the bobbin held by said bobbin-receiving means onto said conveyor means.
