Abstract
Abstract This invention relates generally to textile carding machines and the like, and more particularly to a drive apparatus for driving a feed roll on such a machine so that a constant drive speed is provided and so the drive speed may be conveniently altered by exchanging gears of different ratios, wherein the drive apparatus includes a bracket having at least one vertical side member and a transfer shaft adjustably carried within the vertical side member. A first gear, which is driven by a drive bevel gear carried on a main input shaft, is carried on the transfer shaft, and a draft change gear is removably carried on the transfer shaft for rotation with the first gear. The draft change gear is meshed with a feed roll change gear which is carried on the feed roll drive shaft for driving the feed roll. The draft change gear and the feed roll change gear may be readily removed and replaced to alter the gear ratio of the drive apparatus and the drive speed of the feed roll with the transfer shaft being adjustable to accommodate the change of the gears.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
206 words
Drive apparatus for driving a feed roll on a carding machine and the like comprising: a bracket carried by said carding machine having at least one vertical side member, an elongated longitudinal slot formed in said vertical side member of said bracket, a transfer shaft having one end carried in said slot extended substantially perpendicular from said vertical side member and said slot, said one end being movable in said slot for adjusting the position of said transfer shaft along the length of said slot; a first gear carried on said transfer shaft, means for driving said first gear, a draft change gear carried on said transfer shaft for rotation with said first gear, a feed roll drive shaft carried by said carding machine for driving said feed roll, and a feed roll change gear in meshing relationship with said draft change gear carried by said feed roll drive shaft, whereby said feed roll change gear and said draft change gear may be readily removed and replaced to alter the gear ratio of said drive apparatus and vary the drive speed of said feed roll with said transfer shaft being adjustable longitudinally in said slot so as to accommodate the change of the different size gears.
Claim 2
Dependent Claim
206 words
Drive apparatus for driving a feed roll on a carding machine and the like comprising: a bracket carried by said carding machine having at least one vertical side member, an elongated longitudinal slot formed in said vertical side member of said bracket, a transfer shaft having one end carried in said slot extended substantially perpendicular from said vertical side member and said slot, said one end being movable in said slot for adjusting the position of said transfer shaft along the length of said slot; a first gear carried on said transfer shaft, means for driving said first gear, a draft change gear carried on said transfer shaft for rotation with said first gear, a feed roll drive shaft carried by said carding machine for driving said feed roll, and a feed roll change gear in meshing relationship with said draft change gear carried by said feed roll drive shaft, whereby said feed roll change gear and said draft change gear may be readily removed and replaced to alter the gear ratio of said drive apparatus and vary the drive speed of said feed roll with said transfer shaft being adjustable longitudinally in said slot so as to accommodate the change of the different size gears.
Claim 3
Dependent Claim
98 words
The apparatus of claim 1 further comprising: said transfer shaft including a threaded end extending past a backside of said vertical side member, a substantially rectangular counter-sunk hole formed in said backside of said vertical side member having said elongated longitudinal slot formed therein, fastening means receivable in said rectangular hole and over the threaded end of said shaft for securing said transfer shaft to said vertical side member whereby said fastening means may be loosened so as to permit longitudinal adjustment of said transfer shaft in said longitudinal slot and said fastening means in said rectangular hole.
Claim 4
Dependent Claim
70 words
The apparatus of claim 1 wherein said means for driving said first gear includes a bearing block carried by said bracket, a main input shaft carried by said bearing block extending therethrough, a drive gear carried on one end of said main input shaft, and said drive gear being in meshing relationship with said first gear for driving said first and said draft change gears carried on said transfer shaft.
