Abstract
Abstract A type of tobacco strand identified as the cut variety is conveyed and compressed by a frustum shaped automatic conveyor system. A pressure sensor activated by virtue of the compressed cut tobacco energizes a rotary knife to cut off a desired volumetric quantity of the cut tobacco. Another type of tobacco identified as the short variety is conveyed by a second automatic conveyor system. The two types of tobacco are commingled on a common weighing mechanism to produce a predetermined quantity by weight of a mixed variety.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
128 words
A method for measuring a desired weight quantity of tobacco by means of a determination of a volumetric quantity of tobacco, comprising the steps of: preparing a quantity of cut variety tobacco strands for processing through a feed supply tube to a filler conveyor tube, the conveyor tube having a frustum configuration and having an inlet end and an outlet end of smaller crosssectional area than said inlet end for compressing the cut tobacco strands, mechanically conveying the compressed cut tobacco strands through said conveyor tube toward said smaller outlet end, and the protruding compressed cut tobacco strands moving from the outlet end exerts a pressure on a pressure sensor arrangement for actuating a rotary knife to cut a desired volumetric quantity of the compressed cut tobacco strands.
Claim 2
Independent Claim
128 words
A method for measuring a desired weight quantity of tobacco by means of a determination of a volumetric quantity of tobacco, comprising the steps of: preparing a quantity of cut variety tobacco strands for processing through a feed supply tube to a filler conveyor tube, the conveyor tube having a frustum configuration and having an inlet end and an outlet end of smaller crosssectional area than said inlet end for compressing the cut tobacco strands, mechanically conveying the compressed cut tobacco strands through said conveyor tube toward said smaller outlet end, and the protruding compressed cut tobacco strands moving from the outlet end exerts a pressure on a pressure sensor arrangement for actuating a rotary knife to cut a desired volumetric quantity of the compressed cut tobacco strands.
Claim 3
Dependent Claim
30 words
A method according to claim 1, wherein the mechanical conveying step is performed by a plurality of movably mounted pins operatively arranged in an elongated slot of the filler tube.
Claim 4
Dependent Claim
57 words
A method according to claim 1, wherein the compressed cut tobacco strands are processed to a weighing mechanism positioned below said conveyor tube and the desired weight quantity of tobacco strands is achieved by means of including a desired quantity of additional tobacco of the short variety type to supplement the quantity of the compressed cut tobacco.
Claim 5
Independent Claim
122 words
A device for measuring a desired weight quantity of tobacco by means of a determination of a volumetric quantity of tobacco, comprising a filler tube having an elongated slot and having an inlet end and an outlet end of smaller cross-sectional area than said inlet end; a pressure sensor arrangement; a conveyor operatively mounted within said elongated slot for conducting the tobacco strands through said filler tube; means controlled by said pressure sensor arrangement for driving said conveyor; said filler tube having a frustum configuration for compressing the tobacco strands toward said smaller outlet end; and a knife means movably mounted adjacent said outlet end and controlled by said pressure sensor arrangement for cutting a desired volumetric quantity of the tobacco strands.
Claim 6
Independent Claim
122 words
A device for measuring a desired weight quantity of tobacco by means of a determination of a volumetric quantity of tobacco, comprising a filler tube having an elongated slot and having an inlet end and an outlet end of smaller cross-sectional area than said inlet end; a pressure sensor arrangement; a conveyor operatively mounted within said elongated slot for conducting the tobacco strands through said filler tube; means controlled by said pressure sensor arrangement for driving said conveyor; said filler tube having a frustum configuration for compressing the tobacco strands toward said smaller outlet end; and a knife means movably mounted adjacent said outlet end and controlled by said pressure sensor arrangement for cutting a desired volumetric quantity of the tobacco strands.
Claim 7
Dependent Claim
42 words
A device according to claim 4, wherein said conveyor includes a plurality of pins of increasing height from said inlet end to said outlet end, and a movably mounted means associated with said pins for providing a rotary motion to said pins.
Claim 8
Dependent Claim
45 words
A device according to claim 4, includes a weighting mechanism positioned below said conveyor for receiving said cut variety tobacco strands and means associated with said weighing mechanism for supplying additional tobacco of the short variety type to complete a desired weight quantity of tobacco.
Claim 9
Dependent Claim
72 words
A device according to claim 6, wherein said means for supplying additional tobacco of the short type comprises a supply tube for containing a quantity of short tobacco, a vibrator conveyor for moving the short tobacco into said weighing mechanism, means associated with said supply tube and said vibrator conveyor and including a pin roll arrangement for supplying a desired quantity of short tobacco from said supply tube to said vibrator conveyor.
