The axes e, e,f, /, of these cylinders (&g. 12), should be well fitted into their plummer box-bearings, so as to prevent any lateral swagging, which would greatly injure their operation. The raised position of the cover is obvious in fig. 11, the hinge being placed at B. By means of the saw-gin one man, with the aid of a water-wheel possessing a two-horse power, can clean 5,000 pounds of seed cotton in a day, eighty saws being mounted upon his machine. The clean wool forms generally onefourth of the weight of the seed cotton, and sometimes so much as twenty-seven per cent.

Joseph Eubank, of Kentucky, has proposed to make the saw-gin still more automatic in its performance, by supplying the seed cotton not by hand, but by a feeding-apron, similar to what is employed in the cotton carding-machines. This apron is destined to carry forward the cotton at the proper rate towards the saw-teeth, where a roller set with iron wire fangs seizes the cotton, and throws it briskly against the sawgin cylinder. Cotton wool is now generally condensed into compact bales for facility of transport, by the aid of the hydraulic press; for which purpose a wooden case is built up, consisting of several square frames piled over each other, and then fastened together at the corners by moveable bolts. This chest frame has the same dimensions in its ar...
