MECHANICS AND USEFUL ARTS. 35 



Clover and Timothy Seed Harvester. This machine, the invention 

 of Mr. J. A. AYagner, of Steubcn Co., X. Y., is essentially a simple 

 frame and box mounted on wheels, in front of which is a cylinder set 

 with spiral knives, acting in concert with curved spring teeth, in com- 

 bination with a straight knife, which forms a perfect shear, that severs 

 the heads from the stalk, which are at the same moment discharged in 

 the box. The teeth bein<T made to spring and vibrate, it matters not

how thick or stalky the clover is, not a particle can escape being cut, 

 or allow the teeth to become clogged. The machine is so constructed 

 that it can be adjusted to the height of the clover and timothy. With 

 the aid of one boy and a horse, this machine will harvest from ten to 

 twelve acres per day. 



Salmon's Improved Grain Cleaner. This machine is very unlike the 

 ordinary fanning mill, though answering the same purpose, and even 

 effecting much more, for by slight changes in the force and direction 

 of the blast, wheat can be separated from chess, cockle, garlic, smut, 

 white-heads, and other impurities, as well as from grass seed, saving 

 that and separating the different kinds of grain and grass from one 

 another. The wind-wheel is made of iron, 16 inches diameter, 18 

 inches long, and is placed in an air-tight iron trunk at the bottom of 

 the frame, which is 3 feet 10 inches high, 2 feet wide, and 2 feet 10 

 inches long. The wind-wheel is driven by a cog wheel 2 feet diame- 

 ter, which gives the fan great velocity, sending the air up a tight trunk 

 through which the grain is falling from the sieves, which are not shaken 

 sideways, like the common fan-mills, requiring a good deal of extra 

 room, but are jogged in front by a cam on the shaft of the driving 

 wheel. The sieves, five in number, for different grain, are made fine 

 at the end where the grain first strikes them, to let through fine seeds, 

 and coarse at the other end, through which the wheat falls on the 

 inclined plane, and through the wind-spout into a receiver at the bottom, 

 The wind-spout at the back of the mill can be closed in part, or wholly, 

 by which a little blast is allowed, or all turned out through the sieves. 



This machine is very simple in its whole construction and operation, 

 and quite portable, weighing only from 125 to 135 pounds. It was 

 patented in July, 1853, and originated in the great wheat region of 

 Northern Illinois, where the want of a perfect grain cleaner has long 

 been felt the wheat from Chicago beino; crenerallv several cents be-

low that of New York, on account of the very imperfect manner in 

 which it is cleaned. 



Child's Grain Separator. The principal improvement of this ma- 

 chine upon the old fanning mill is an attachment which causes the 

 grain to fall through a draft of air, created by suction of the fan, so 

 strong that the grain is held in suspension until all the light particles 

 are separated and blown out another way. 



Harg rave's Corn Husking ^Machine. In this machine the ears of 

 corn are placed in little troughs of a horizontal wheel placed on the 

 top of a frame, and turned by a crank. As they pass round, a chisel 

 comes down, separates the stalk from the cob and pushes out the ear 

 and returns ready for another, as it comes around. Another contrivance
