Abstract
Abstract A machine for winding yarn packages and including a device for scanning a series of packages being wound on a spinning or twisting machine, or the like, and providing a signal for initiating doffing of full packages. A pair of sensing elements are responsive to signals from opposite portions of a full package for actuating a signal device to commence the doffing operation. These sensing elements are sensitive, one to the signals from each of opposite portions of the full package, and are connected so that only when both of the sensing elements are actuated is a circuit completed to the signal device which initiates doffing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
125 words
Apparatus for indicating the size of a package being wound comprising, a plurality of light sources directed toward said package being wound and focused to define the boundaries of a zone of predetermined dimension corresponding to a predetermined size to which the package is to be wound, light receiving means directed toward said boundaries, said light receiving means being located on the same side of said package as said light soUrces and being operable to receive light reflected by the boundaries of said package from said light sources when said package attains said predetermined size, and signal means connected with said light receiving means to produce an indication when the reflected light from the boundaries of the package is received by the light receiving means.
Claim 2
Dependent Claim
125 words
Apparatus for indicating the size of a package being wound comprising, a plurality of light sources directed toward said package being wound and focused to define the boundaries of a zone of predetermined dimension corresponding to a predetermined size to which the package is to be wound, light receiving means directed toward said boundaries, said light receiving means being located on the same side of said package as said light soUrces and being operable to receive light reflected by the boundaries of said package from said light sources when said package attains said predetermined size, and signal means connected with said light receiving means to produce an indication when the reflected light from the boundaries of the package is received by the light receiving means.
Claim 3
Dependent Claim
26 words
Apparatus as set forth in claim 1 wherein the boundaries of said zone correspond to a predetermined diameter to which the package is to be wound.
Claim 4
Dependent Claim
30 words
Apparatus as set forth in claim 1 including lens means for focusing the light reflected by the boundaries of the package from said light sources to said light receiving means.
Claim 5
Dependent Claim
29 words
Apparatus as set forth in claim 5 including means for serially connecting said photosensitive elements to thereby provide said indication from concurrent operation of all of said photosensitive elements.
Claim 6
Dependent Claim
18 words
Apparatus as set forth in claim 1 wherein said light receiving means is a plurality of photosensitive elements.
Claim 7
Dependent Claim
44 words
Apparatus as set forth in claim 1 including a carriage for mounting said light sources and said light receiving means, and means for moving said carriage relative to said package to permit said light sources and light receiving means to periodically scan said package.
Claim 8
Dependent Claim
35 words
Apparatus as set forth in claim 7 including means for arranging a plurality of said packages in juxtaposition, and means mounting said carriage for movement relative to each said packages to sequentially scan the packages.
Claim 9
Dependent Claim
33 words
Apparatus as set forth in claim 1 including package doffing means, and means connecting said signal means and said package doffing means to initiate doffing of said package when said indication is produced.
