Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
165 words
A device for compensating changes in roving winding tension in a spinning machine, comprising a pair of cone drums mounted for rotation in said spinning machine, a belt-like member stretched around said cone drums to transmit rotation of one of said cone drums to the other, a belt shifter associated with said belt-like member to move said belt-like member along the length of said cone drums, a moving member capable of movement to energize said belt shifter, a link mechanism including at least two link elements pivotably connected together, said belt shifter being connected through said link elements with said moving member, and guide means having a cam surface at a position apart by a predetermined distance from the movement locus of said link mechanism, a part of said link mechanism being engaged with the cam surface of said guide means so that the movement of said moving member is transferred to said belt shifter while being subject to the influence of said cam surface.
Claim 2
Independent Claim
165 words
A device for compensating changes in roving winding tension in a spinning machine, comprising a pair of cone drums mounted for rotation in said spinning machine, a belt-like member stretched around said cone drums to transmit rotation of one of said cone drums to the other, a belt shifter associated with said belt-like member to move said belt-like member along the length of said cone drums, a moving member capable of movement to energize said belt shifter, a link mechanism including at least two link elements pivotably connected together, said belt shifter being connected through said link elements with said moving member, and guide means having a cam surface at a position apart by a predetermined distance from the movement locus of said link mechanism, a part of said link mechanism being engaged with the cam surface of said guide means so that the movement of said moving member is transferred to said belt shifter while being subject to the influence of said cam surface.
Claim 3
Dependent Claim
18 words
The device as set forth in claim 1, wherein said guide means is composed of a flexible material.
Claim 4
Dependent Claim
44 words
The device as set forth in claim 2, wherein said guide means is suspended and supported by adjustable means and the cam surface of said guide means is adapted to spinning conditions of a roving to be wound by adjustment of said adjustable means.
Claim 5
Dependent Claim
14 words
The device as set forth in claim 3, wherein said adjustable means are bolts.
Claim 6
Dependent Claim
35 words
The device as set forth in claim 2, wherein said part of said link mechanism to be engaged with the cam surface is composed of a roller connected at a connection of said link elements.
Claim 7
Dependent Claim
33 words
The device as set forth in claim 5, wherein said two link elements are biased toward each other by a resilient member to ensure the engagement of said roller with the cam surface.
Claim 8
Dependent Claim
59 words
The device as set forth in claim 1, wherein said guide means is composed of a link mechanism including a plurality of members, and every two adjacent members are pivotably connected to each other, and individual members are supported so that their positions are changed with respect to said link mechanism connecting said belt shifter with said moving member.
