Abstract
Abstract There is disclosed a device for feeding a filament from a supply thereof to a machine wherein said filament may be used for knitting, weaving or spooling. A storage drum is fixedly mounted at one end thereof to a frame member. The filament is guided in a first direction, from a supply thereof to a position adjacent said one end of the drum, where it is wound about the drum to form a plurality of windings which advance in a second direction, opposite to said first direction, toward the other end of the drum. The filament is drawn off the drum in said second direction to the other end of the drum, where it reverses direction and travels through an internal passage in the drum, in said first direction, and through an aperture in the frame member, toward the machine requiring said filament.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
306 words
A device for feeding yarn from a yarn package to a textile producing machine, comprising: a. a frame adapted for securement to said machine, b. a yarn storage member, c. support means fixedly mounted on said frame means and having secured thereto said storage member with one of its ends proximate to said frame member and the other of its ends distal thereto, whereby said storage member is fixed against rotation relative to said frame member, d. yarn winding means mounted for rotation on said support means between said frame member and said storage member, and having yarn guide means for winding said yarn about said storage member adjacent said one end thereof, for forming on said storage member a plurality of yarn windings which advance toward the other end of the storage member, said yarn being withdrawn from said yarn package in response to the rotation of said yarn winding means, e. said winding means having sleeve means extending axially of said storage member and adapted to cover said yarn windings on said storage member, said yarn guide means being located at one end of said sleeve means, f. means for detecting a predetermined quantity of yarn wound onto said storage member comprising a light source and a photocell mounted internally of said storage member, said drum being provided with a pair of apertures positioned relative to said light source and said photocell so that light emanating from said light source passes through one of said apertures, is reflected Off the inner surface of said sleeve means, passes through the other of said apertures, and impinges on said photocell, whereby said photocell is energized when neither of said apertures is covered by the yarn wound onto the drum, and h. control means responsive to said detecting means for controlling the rotation of said winding means.
Claim 2
Independent Claim
306 words
A device for feeding yarn from a yarn package to a textile producing machine, comprising: a. a frame adapted for securement to said machine, b. a yarn storage member, c. support means fixedly mounted on said frame means and having secured thereto said storage member with one of its ends proximate to said frame member and the other of its ends distal thereto, whereby said storage member is fixed against rotation relative to said frame member, d. yarn winding means mounted for rotation on said support means between said frame member and said storage member, and having yarn guide means for winding said yarn about said storage member adjacent said one end thereof, for forming on said storage member a plurality of yarn windings which advance toward the other end of the storage member, said yarn being withdrawn from said yarn package in response to the rotation of said yarn winding means, e. said winding means having sleeve means extending axially of said storage member and adapted to cover said yarn windings on said storage member, said yarn guide means being located at one end of said sleeve means, f. means for detecting a predetermined quantity of yarn wound onto said storage member comprising a light source and a photocell mounted internally of said storage member, said drum being provided with a pair of apertures positioned relative to said light source and said photocell so that light emanating from said light source passes through one of said apertures, is reflected Off the inner surface of said sleeve means, passes through the other of said apertures, and impinges on said photocell, whereby said photocell is energized when neither of said apertures is covered by the yarn wound onto the drum, and h. control means responsive to said detecting means for controlling the rotation of said winding means.
Claim 3
Dependent Claim
39 words
A device in accordance with claim 1, wherein said yarn storage member and said support means have internal passages in communication with each other through which the yarn wound onto the storage member travels as it is withdrawn therefrom.
Claim 4
Dependent Claim
39 words
A device in accordance with claim 2, wherein the yarn withdrawn from said storage member travels toward the other end of said storage member, reverses direction, and enters said internal passages of said storage member and said support means.
