. Catalogue of agricultural and horticultural implements ... 38 AGRICULTURAL AND HORTICULTURAL TOOLS. The machine is a perfect self-leeder, without any extra and complicated fixture to perform that part of the work. For this kind of cutters, crooked or spiral knives have been mostly used, which could not, without much difficulty, be properly sharpened or replace(i except by tlie maker, subjecting purchasers to much inconvenience and ex- pense. Some manufacturers confine the knives to the cylinder by means oi flanges, gloats, and screws. Thus the knives are weakened, and the screws are liable to be lost or injured, and the flanges prevent the knives being placed upon the cylinder so near each other as to cut the straw as short as is by many thought to be necessary. Important imj)rovements have recently been made in the construction of this kind of machines, by using straight knives, confined by a simple cap, and placed in such a manner upon the cylinder that they perform the work in every respect as easily and expeditiously as the spiral knives. Thus improved, the machines possess several very important advantages. The straight, as in figure 41, are readily ground or sharpened by the purchaser ; and they can be replaced by a common blacksmith when worn out or broken. The knives are made heavier and attached to the cylinder without sloats or screws, and are confined at both ends and supportea in the middle in a manner much stronger and less complicated, thus leaving the strength of the knives unimpaired, and avoiding the great liability to twist, cripple, and break. The manner of attaching the knives to the cylinder admits of their being placed near each other, so as to cut as short as is desirable, and the hide-roller, when used with straight knives properly set, will last much lorger than when used with the spiral knife.
