US4216642A — Tobacco harvesting method and apparatus

Claim 1

Independent Claim 277 words

Apparatus for use in harvesting tobacco plants comprising: a chassis; ground-engaging means supporting the chassis for movement along a row of the plants to be harvested; means for effecting said movement of the chassis; a plant cutter supported by said chassis in disposition for severing plants from the ground during said movement of the chassis; an operator's station on the chassis so disposed that an operator located at said station may take manual control of the plants upon said severance by said cutter; a stake carried by said chassis in an upright disposition closely adjacent said operator's station for accumulating severed plants successively impaled on the stake by the operator; a pair of decks carried by the chassis on opposite fore-and-aft sides of said stake and said station, one of said decks being disposed to underlie and support the accumulation of plants on the stake to prevent damage to the plants while the stake is being loaded, said stake being removably mounted in said upright disposition for periodic replacement when the stake is loaded with plants; and means carried by said chassis closely adjacent said station for storing a supply of replacement stakes, the other of said decks being disposed for supporting loaded stakes that have been removed from said upright disposition and deposited on said other deck, said cutter, said decks, said stake, and said storing means all being so located with respect to said station that the operator may carry out the functions of taking the severed plants from the cutter, impaling them on the stakes, depositing loaded stakes on said other deck, and replacing the loaded stakes with new stakes without leaving said station.

Claim 2

Dependent Claim 277 words

Apparatus for use in harvesting tobacco plants comprising: a chassis; ground-engaging means supporting the chassis for movement along a row of the plants to be harvested; means for effecting said movement of the chassis; a plant cutter supported by said chassis in disposition for severing plants from the ground during said movement of the chassis; an operator's station on the chassis so disposed that an operator located at said station may take manual control of the plants upon said severance by said cutter; a stake carried by said chassis in an upright disposition closely adjacent said operator's station for accumulating severed plants successively impaled on the stake by the operator; a pair of decks carried by the chassis on opposite fore-and-aft sides of said stake and said station, one of said decks being disposed to underlie and support the accumulation of plants on the stake to prevent damage to the plants while the stake is being loaded, said stake being removably mounted in said upright disposition for periodic replacement when the stake is loaded with plants; and means carried by said chassis closely adjacent said station for storing a supply of replacement stakes, the other of said decks being disposed for supporting loaded stakes that have been removed from said upright disposition and deposited on said other deck, said cutter, said decks, said stake, and said storing means all being so located with respect to said station that the operator may carry out the functions of taking the severed plants from the cutter, impaling them on the stakes, depositing loaded stakes on said other deck, and replacing the loaded stakes with new stakes without leaving said station.

Claim 3

Dependent Claim 34 words

Apparatus as claimed in claim 1, wherein said other deck is provided with means swingably mounting the same on the chassis for swinging between a generally horizontal supporting position and an inclined dumping position.

Claim 4

Dependent Claim 36 words

Apparatus as claimed in claim 1, wherein said cutter is disposed generally to one laterally outboard side of said operator's station, said stake being disposed generally to the opposite laterally outboard side of said operator's station.

Claim 5

Dependent Claim 53 words

Apparatus as claimed in claim 1, wherein said ground-engaging means includes a pair of steerable wheels; and plant-engaging guidance mechanism operably coupled with said wheels for maintaining the chassis in a predetermined relationship with a plant row as the chassis moves along the latter with said mechanism engaging standing plants of the row.

Claim 6

Dependent Claim 20 words

Apparatus as claimed in claim 4, wherein said mechanism includes means yieldably biasing said wheels toward a straight forward position.

Claim 7

Dependent Claim 29 words

Apparatus as claimed in claim 1, wherein said movement-effecting means includes a manually manipulable control at said operator's station for regulating the speed of said movement of the chassis.

Claim 8

Dependent Claim 227 words

Apparatus for use in harvesting tobacco plants comprising: a chassis; ground-engaging means supporting the chassis for movement along a row of the plants to be harvested; means for effecting said movement of the chassis; a plant cutter supported by said chassis in disposition for severing plants from the ground during said movement of the chassis; an operator's station on the chassis so disposed that an operator located at said station may take manual control of the plants upon said severance by said cutter; a stake carried by said chassis in an upright disposition adjacent said operator's station for accumulating severed plants successively impaled on the stake by the operator; means removably mounting the stake on the chassis in said upright disposition for periodic replacement when the stake becomes loaded with plants; and means on said chassis for supporting loaded stakes upon removal thereof from said upright disposition, said loaded-stake supporting means including a deck located adjacent said operator's station, said deck being provided with means swingably mounting the same on the chassis for swinging between a generally horizontal supporting position and an inclined dumping position, said mounting means adapting said deck for dumping to the rear of the chassis, said mounting means including structure supporting said deck for shifting thereof to a laterally offset position relative to the path of travel of the chassis prior to dumping.

Claim 9

Dependent Claim 227 words

Apparatus for use in harvesting tobacco plants comprising: a chassis; ground-engaging means supporting the chassis for movement along a row of the plants to be harvested; means for effecting said movement of the chassis; a plant cutter supported by said chassis in disposition for severing plants from the ground during said movement of the chassis; an operator's station on the chassis so disposed that an operator located at said station may take manual control of the plants upon said severance by said cutter; a stake carried by said chassis in an upright disposition adjacent said operator's station for accumulating severed plants successively impaled on the stake by the operator; means removably mounting the stake on the chassis in said upright disposition for periodic replacement when the stake becomes loaded with plants; and means on said chassis for supporting loaded stakes upon removal thereof from said upright disposition, said loaded-stake supporting means including a deck located adjacent said operator's station, said deck being provided with means swingably mounting the same on the chassis for swinging between a generally horizontal supporting position and an inclined dumping position, said mounting means adapting said deck for dumping to the rear of the chassis, said mounting means including structure supporting said deck for shifting thereof to a laterally offset position relative to the path of travel of the chassis prior to dumping.

Claim 10

Dependent Claim 46 words

Apparatus as claimed in claim 7, wherein said structure includes a pair of fore-and-aft spaced, laterally extending tracks on said chassis and corresponding fore-and-aft spaced track followers on said deck, the rear follower having transverse pivot means associated therewith for permitting said swinging of the deck.

Claim 11

Dependent Claim 51 words

Apparatus as claimed in claim 8, wherein said tracks are configured to confine said followers against escape, the forward track having opening means therein corresponding to said laterally offset position of the deck and permitting temporary removal of the forward follower from the forward track during said swinging of the deck.
