Abstract
Abstract An instrument for separating out any one or more of the components of any given sample of fluff. The instrument includes a base having an annular opening formed in its upper surface. A spindle is journaled in the base, and supports a sieve and enclosure over itself. A compressed air bar is located between the sieve and the spindle, to allow compressed air to escape through the sieve and impact on the fluff sample in the enclosure. A motor is provided to turn the chamber, sieve and enclosure while the air bar is held stationary. The motor turns the spindle by any suitable arrangement such as belt drive, rim drive, direct drive or any other appropriate arrangement. A vacuum motor and assembly communicates with the annular base opening to draw components to be separated from the sample through the sieve, spindle and base, leaving only the remaining components in the enclosure above the sieve. These components are compared to determine the quality of the fluff sample.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
173 words
An apparatus for testing for the amount of fiberization of a particular sample of fluff, comprising: a base for providing support and having an opening in its upper surface; a spindle journaled to said base and having at least one opening for communicating with the opening in said base; a testing sieve supported by said spindle and disposed on the opposite side of said spindle from said base, the openings of said sieve being sufficiently large to pass the great majority of fibers and sufficiently small to prevent the passage of the great majority of knots; an enclosure placed over said sieve; a compressed air bar communicating with a source of compressed air, disposed between said sieve and said spindle, for releasing compressed air through said sieve to impact on the sample; a vacuum means for drawing the fibers through said sieve, said spindle and said base; and means for automatically and continually rotating said spindle and sieve with respect to said air bar, so that the sample is continually and automatically agitated.
Claim 2
Independent Claim
173 words
An apparatus for testing for the amount of fiberization of a particular sample of fluff, comprising: a base for providing support and having an opening in its upper surface; a spindle journaled to said base and having at least one opening for communicating with the opening in said base; a testing sieve supported by said spindle and disposed on the opposite side of said spindle from said base, the openings of said sieve being sufficiently large to pass the great majority of fibers and sufficiently small to prevent the passage of the great majority of knots; an enclosure placed over said sieve; a compressed air bar communicating with a source of compressed air, disposed between said sieve and said spindle, for releasing compressed air through said sieve to impact on the sample; a vacuum means for drawing the fibers through said sieve, said spindle and said base; and means for automatically and continually rotating said spindle and sieve with respect to said air bar, so that the sample is continually and automatically agitated.
Claim 3
Dependent Claim
44 words
An apparatus as recited in claim 1 further comprising timer means for controlling said turning means and allowing an operator to cause the apparatus to run unattended for a predetermined length of time or to interrupt the operation of the apparatus at his discretion.
Claim 4
Dependent Claim
57 words
An apparatus as recited in claim 1 wherein said vacuum means includes an enclosure communicating with the opening of said base, a vacuum motor, a dust filter disposed beyond the vacuum motor, and a catch sieve, the mesh of which is fine enough to catch the great majority of loose fibers before they reach said vacuum motor.
Claim 5
Dependent Claim
26 words
An apparatus as recited in claim 3 further comprising means for opening said vacuum means enclosure to allow removal of fiber buildup on said catch sieve.
Claim 6
Dependent Claim
23 words
An apparatus as recited in claim 1 wherein said turning means includes a motor connected to said spindle by a belt drive arrangement.
Claim 7
Dependent Claim
31 words
An apparatus as recited in claim 1 wherein said turning means includes a motor driving a wheel which bears directly on a rim of said spindle in a rim drive arrangement.
Claim 8
Dependent Claim
24 words
An apparatus as recited in claim 1 wherein said turning means includes a motor connected directly to said spindle in a direct drive arrangement.
Claim 9
Independent Claim
189 words
An apparatus for separating out at least one of the components of a particular sample of fluff, comprising: a base for providing support and having an opening in its upper surface; a spindle journaled to said base and having at least one opening for communicating with the opening in said base; a testing sieve supported by said spindle and disposed on the opposite side of said spindle from said base, the openings of said sieve being sufficiently large to pass the great majority of components to be separated out and sufficiently small to prevent the passage of the great majority of the components not to be separated out; an enclosure placed over said sieve; a compressed air bar communicating with a source of compressed air, disposed between said sieve and said spindle, for releasing compressed air through said sieve to impact on the sample; a vacuum means for drawing the components to be separated out through said sieve, said spindle and said base; and means for automatically and continually rotating said spindle and sieve with respect to said air bar, so that the sample is continually and automatically agitated.
Claim 10
Independent Claim
189 words
An apparatus for separating out at least one of the components of a particular sample of fluff, comprising: a base for providing support and having an opening in its upper surface; a spindle journaled to said base and having at least one opening for communicating with the opening in said base; a testing sieve supported by said spindle and disposed on the opposite side of said spindle from said base, the openings of said sieve being sufficiently large to pass the great majority of components to be separated out and sufficiently small to prevent the passage of the great majority of the components not to be separated out; an enclosure placed over said sieve; a compressed air bar communicating with a source of compressed air, disposed between said sieve and said spindle, for releasing compressed air through said sieve to impact on the sample; a vacuum means for drawing the components to be separated out through said sieve, said spindle and said base; and means for automatically and continually rotating said spindle and sieve with respect to said air bar, so that the sample is continually and automatically agitated.
Claim 11
Dependent Claim
44 words
An apparatus as recited in claim 8 further comprising timer means for controlling said turning means and allowing an operator to cause the apparatus to run unattended for a predetermined length of time or to interrupt the operation of the apparatus at his discretion.
Claim 12
Dependent Claim
61 words
An apparatus as recited in claim 8 wherein said vacuum means includes an enclosure communicating with the opening of said base, a vacuum motor, a dust filter disposed beyond the vacuum motor, and a catch sieve, the mesh of which is fine enough to catch the great majority of loose components to be separated out before they reach said vacuum motor.
Claim 13
Dependent Claim
28 words
An apparatus as recited in claim 10 further comprising means for opening said vacuum means enclosure to allow removal of buildup of separated components on said catch sieve.
Claim 14
Dependent Claim
23 words
An apparatus as recited in claim 8 wherein said turning means includes a motor connected to said spindle by a belt drive arrangement.
Claim 15
Dependent Claim
31 words
An apparatus as recited in claim 8 wherein said turning means includes a motor driving a wheel which bears directly on a rim of said spindle in a rim drive arrangement.
Claim 16
Dependent Claim
24 words
An apparatus as recited in claim 8 wherein said turning means includes a motor connected directly to said spindle in a direct drive arrangement.
