Abstract
Abstract An adjustable drive for a pair of rolls which allows for adjustment of the rolls relative to each other and for backlash take-up in the train of gears driving the rolls. A shaft extension on each roll has a roll gear fixed thereon. The shaft extensions of the rolls turn in bushings. The bushings of one shaft extension are fitted in the overlapped ends of adjusting forks and the bushings of the other shaft extension are fitted in the overlapped ends of horizontal links. Three alignment idler gears and a drive gear mesh with the roll gears. The drive gear and the adjacent alignment gear mesh with each other, and each pair of said gears is connected with vertical links. The drive gear and one of the alignment gears are carried by said forks and the other two alignment gears are carried by said horizontal links. The upper roll is adjustable relative to the lower roll and the outer ends of the forks are adjustable vertically by fork adjusting screws.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
164 words
An adjustable roll drive for cooperating upper and lower rolls having bearings, said adjustable roll drive including a frame, the roll bearings being located in the frame, shaft extensions upon the rolls, a roll gear fixed upon each shaft extension, a pair of generally horizontally disposed adjusting forks having their overlapping inner ends pivoted upon the upper shaft extension, means for vertically adjusting the outer ends of said adjusting forks, a third gear journaled in one of said adjusting forks and meshing with one side of the upper roll gear, an alignment idler gear rotatably mounted in the other adjusting fork and meshing with the other side of said upper roll gear, alignment idler gears meshing with both sides of the lower roll gear, one of said last named alignment idler gears meshing with the third gear and the other meshing with the first named alignment idler gear, means holding the alignment idler gears in engagement, and means for driving said gears and rolls.
