Abstract
Abstract A thread storage and delivery device for conveying a thread from a spool to a working point on a textile machine. The device comprises a drum for receiving and storing a thread reserve. A disk is disposed substantially transverse to the axis of the shaft and is axially slideably mounted on the shaft. The disk has arm portions which extend radially through openings formed in the drum casing, said arms being axially supported on said thread reserve. The arm portions may be inclined upwardly relative to the external drum periphery for permitting the thread to be properly wound on the drum and for causing the thread on the drum to be wedged axially therealong. The disk is urged downwardly of the drum, the movement of the disk depending on the size of the thread reserve. The axial displacement of the disk controls the feed of thread to the drum to permit control over the size of the yarn reserve.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
131 words
A thread storage and delivery device for conveying a thread from a spool to a working point of a textile machine, comprising a storage drum for receiving a thread supply thereon, the storage drum having a plurality of longitudinal openings extending through the wall thereof, disk means substantially nonrotatably connected relative to said drum, said disk means including a plurality of radial arm portions extending through said longitudinal openings and axially supported on said thread supply, mounting means coacting between said disk means and said drum for permitting only linear reciprocation of said disk means relative to said drum in a direction parallel to the axis of said drum, and control means controlling the thread feed to the drum, said control means being operable by the movement of said disk means.
Claim 2
Dependent Claim
131 words
A thread storage and delivery device for conveying a thread from a spool to a working point of a textile machine, comprising a storage drum for receiving a thread supply thereon, the storage drum having a plurality of longitudinal openings extending through the wall thereof, disk means substantially nonrotatably connected relative to said drum, said disk means including a plurality of radial arm portions extending through said longitudinal openings and axially supported on said thread supply, mounting means coacting between said disk means and said drum for permitting only linear reciprocation of said disk means relative to said drum in a direction parallel to the axis of said drum, and control means controlling the thread feed to the drum, said control means being operable by the movement of said disk means.
Claim 3
Dependent Claim
131 words
A thread storage and delivery device for conveying a thread from a spool to a working point of a textile machine, comprising a storage drum for receiving a thread supply thereon, the storage drum having a plurality of longitudinal openings extending through the wall thereof, disk means substantially nonrotatably connected relative to said drum, said disk means including a plurality of radial arm portions extending through said longitudinal openings and axially supported on said thread supply, mounting means coacting between said disk means and said drum for permitting only linear reciprocation of said disk means relative to said drum in a direction parallel to the axis of said drum, and control means controlling the thread feed to the drum, said control means being operable by the movement of said disk means.
Claim 4
Dependent Claim
131 words
A thread storage and delivery device for conveying a thread from a spool to a working point of a textile machine, comprising a storage drum for receiving a thread supply thereon, the storage drum having a plurality of longitudinal openings extending through the wall thereof, disk means substantially nonrotatably connected relative to said drum, said disk means including a plurality of radial arm portions extending through said longitudinal openings and axially supported on said thread supply, mounting means coacting between said disk means and said drum for permitting only linear reciprocation of said disk means relative to said drum in a direction parallel to the axis of said drum, and control means controlling the thread feed to the drum, said control means being operable by the movement of said disk means.
Claim 5
Dependent Claim
23 words
A device according to claim 1, wherein said control means includes switch means disposed for operation by the movement of said disk means.
Claim 6
Dependent Claim
44 words
A device according to claim 1, wherein said arm portions project radially outwardly beyond the external periphery of said drum and extend in nonperpendicular relation relative to said drum, said arm portions defining a substantially truncated conical surface in surrounding relationship to said drum.
Claim 7
Dependent Claim
36 words
A device according to claim 1, wherein said drum is disposed with its longitudinal axis oriented substantially vertically, and wherein said arm portions extEnd radially outwardly and upwardly relative to the external periphery of said drum.
Claim 8
Dependent Claim
26 words
A device according to claim 1, wherein said arm portions are inclined at an angle of approximately 45 *relative to the external periphery of said drum.
Claim 9
Dependent Claim
61 words
A device according to claim 1, wherein said disk means includes a central disk portion disposed within the interior of said drum and having said arm portions fixedly secured to and extending radially outwardly and axially upwardly from the external periphery thereof, said central disk portion comprising a planar, plate-like member disposed substantially perpendicular to the longitudinal axis of said drum.
Claim 10
Dependent Claim
60 words
A device according to claim 1, wherein said mounting means includes a substantially vertically directed shaft with said drum being coaxially and concentrically supported on said shaft, said disk means including an elongated hub portion slideably supported on said shaft for axial movement therealong, and biasing means including spring means urging said disk means axially downwardly relative to said drum.
Claim 11
Dependent Claim
64 words
A device according to claim 7, further including means supporting said drum for rotation, drive means interconnected to said drum for permitting selected rotation thereof, and said control means being operatively connected to said drive means for controlling the operation thereof, said control means being disposed for actuation by said disk means when said disk means is in one of its extreme axial positions.
Claim 12
Dependent Claim
110 words
A device according to claim 8, wherein said control means comprises electrical switch means connected in series with said drive means for controlling the operation thereof, said electrical switch means being disposed for actuation by said disk means when said disk means is in its uppermost axial position to cause deenergization of said drive means to prevent further thread from being wound onto said spool, movement of said disk means to its lowermost axial position causing same to disengage said switch means whereby said switch means will then cause energization of said drive means to cause rotation of said drum to permit further thread to be wound onto said spool.
Claim 13
Dependent Claim
39 words
A device according to Claim 1, wherein said mounting means includes shaft means coaxial with said storage drum, and said disk means being slideably supported on said shaft means for linear movement in the axial direction of said drum.
Claim 14
Dependent Claim
109 words
A device according to claim 10, wherein said disk is axially movable relative to said drum between first and second positions, biasing means for normally urging said disk means toward said first position, winding means associated with said drum for permitting thread to be selectively wound thereon, and said control means associated with said winding means for controlling the operation thereof, said control means being disposed for coaction with said disk means when said disk means is in one of said axial positions for causing activation of said winding means to permit further thread to be wound onto said drum when said disk means is in said first position.
Claim 15
Dependent Claim
41 words
A device according to claim 11, wherein said control means includes switch means disposed for contact and actuation by said disk means when said disk means is in said second position, said second position being disposed vertically above said first position.
Claim 16
Dependent Claim
50 words
A device according to Claim 1, wherein said arm portions project radially outwardly beyond the external periphery of said drum, and a continuous annular rim fixedly secured to said arm portions adjacent the outer edges thereof, said annular rim being disposed externally of and in surrounding relationship to said drum.
