Abstract
Abstract A thread storage and supply device for textile machines comprising a storage drum which is nonrotatably journaled at the free end of an axle, which axle is prevented from rotating by means of a laterally displaced journal pin which extends parallel to the longitudinal direction of the axle and is rotatably positioned in a rotatably journaled disc. The device further comprises a thread supply means which is journaled on the axle, which support means can be set in rotation and which winds the thread upon the storage drum. The rotatably journaled disc is connected, for the purpose of synchronous rotation, to the rotating thread supply means by a connecting pin which is rigidly mounted on the thread supply means and which passes through a radial slot in the rotatably journaled disc. The thread supply means includes a corotational channel for the thread.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
220 words
A thread storage and supply device for a textile machine, comprising an axle having means associated with one end thereof for maintaining the axle in a nonrotatable condition, the axle having a free end portion adjacent the other end thereof, a thread storage drum nonrotatably mounted relative to said axle and disposed in surrounding relationship to the free end portion thereof, supply means for permitting a thread to be wound onto said drum, said supply means including a thread supply member disposed adjacent one end of said drum and rotatably journaled on said axle for rotation about the axis thereof, rotatable disc means disposed adjacent said supply member on the side thereof remote from said drum, said disc means being rotatable about an axis which is parallel to but radially displaced from the axis of said axle, and means drivingly interconnecting the disc means and the supply member for synchronous rotation, the improvement wherein said interconnecting means includes a thread guide pin mounted on the thread supply member and passing through a radial slot formed in said disc means so that the thread guide pin passes axially through both the supply member and the disc means, the thread guide pin having a channel extending axially therethrough for permitting passage of a thread which is to be wound on the drum.
Claim 2
Dependent Claim
220 words
A thread storage and supply device for a textile machine, comprising an axle having means associated with one end thereof for maintaining the axle in a nonrotatable condition, the axle having a free end portion adjacent the other end thereof, a thread storage drum nonrotatably mounted relative to said axle and disposed in surrounding relationship to the free end portion thereof, supply means for permitting a thread to be wound onto said drum, said supply means including a thread supply member disposed adjacent one end of said drum and rotatably journaled on said axle for rotation about the axis thereof, rotatable disc means disposed adjacent said supply member on the side thereof remote from said drum, said disc means being rotatable about an axis which is parallel to but radially displaced from the axis of said axle, and means drivingly interconnecting the disc means and the supply member for synchronous rotation, the improvement wherein said interconnecting means includes a thread guide pin mounted on the thread supply member and passing through a radial slot formed in said disc means so that the thread guide pin passes axially through both the supply member and the disc means, the thread guide pin having a channel extending axially therethrough for permitting passage of a thread which is to be wound on the drum.
Claim 3
Dependent Claim
64 words
A device according to claim 1, wherein the thread guide pin extends continuously from the side of the disc means remote from the storage drum to a point located adjacent the outer thread storage surface of the drum, said thread guide pin extending parallel to the axis of said axle but being positioned outside of an imaginary extension of the storage drum outer surface.
Claim 4
Dependent Claim
59 words
A device according to claim 1, wherein the channel has a flat rectangular cross section, wherein the thread guide pin is rotatably supported on the supply member, and gear means drivingly connected to said thread guide pin for maintaining said pin and the slot therein in a constant relative position with respect to the surface of the storage drum.
Claim 5
Dependent Claim
55 words
A device according to claim 1, wherein the means for preventing rotation of the axle includes a journal pin which is fixed to the axle and radially displaced therefrom and extends parallel to the axis thereof, said journal pin having said disc means rotatably journaled thereon and defining the rotational axis of said disc means.
Claim 6
Dependent Claim
68 words
A device according to claim 3, wherein the gear means is formed from a first gear which is rigidly secured on the axle of the storage drum, an intermediate gear which meshes with said first gear and is rotatably journaled in a part which rotates with the guide pin, and a second gear which meshes with said intermediate gear and which is rigidly mounted on said guide pin.
