170 BOARD OF AGRICULTURE. 



Robinson & Co., Richmond, Indiana, exhibit one of their ten horse Bonanza Sepa- 

 rators. This machine uses riddles of large surface, the width of which is in excess 

 of the length of the cj'linder. The straw is carried from the machine by pickers 

 extending from the back of the cylinder to the front of the machine, equalizing the 

 straw as it passes away from-the machine. It has a patent device for preventing the 

 heating of the cylinder journals, and an arrangement for putting on the main belt 

 without unlacing it. The throat is peculiarly constructed — affording the cylinder 

 an excellent "suck," making the machine easy to feed, and quite free from dust. 

 It has patent pickers which work into the straw from above, and to all appearances 

 do the work in an admirable manner. It has large riddle surface, and extended 

 tailing spout, to which any grain that may be carried or blown over the stacker is 

 returned and carried up by the elevator. This machine has clover huUer attach- 

 ment. It requires but -a few moments to change for hulling clover, which is done 

 by regulating the concave adjuster without stopping the machine. The machine is 

 of low speed, and remains steady while in motion without brace or prop. 



Ea(jle Machine Works, Indianapoli.% Indiana, has one of their Oscillator Separa- 

 tors on exhibition. By its its construction it is impossible to throw grain from 

 cylinder back into the straw. Extended riddles and internal agitators; runs with 

 one bf It. Double cylinder used for hulling clover seed, as well as all kinds of grain 

 in plain threshing. A little back of the cylinder is arranged a revolving deflector, 

 throwing the straw and grain from the cylinder onto the oscillating floor, making a 

 draft which takes the dust from the feeder. This oscillating floor is divided into 

 four sections, each moved by an ingenious contrivance of cranks, giving them a 

 double motion to which is added the aid of carrying or lifting fingers, thus assur- 

 ing the passage of the straw from the macliine, and a complete separation from the 

 grain. Any amount of straw, either dry or damp, that may pass through the cyl- 

 inder can not possibly choke or obstruct i he oscillator, and will always be separated 

 from the grain. 



The same firm exhibited one of their Victor grain threshers. This machine ia 

 strong, durable, and of large capacity, and on general principles a good machine 



NichoL% Shepherd <fc Co., Battle Creek, Mich., exhibited one of their Vibrator 

 separators. This machine has two vibrators, one over the other, hung on suspen- 

 sions rods, and have a forward and backward motion in opposite directions. The 

 upper vibrator allows the grain to pass through transverse slats onto the lower one. 

 The lower shaker extends from under the concave to the riddles, and has a tight 

 floor, over which the grain passes to the riddles. The back end of this floor is 

 perforated so that the grain is equally distributed over the riddles. . Over the upper 

 shaker are six sets of fingers, which are inserted in a transverse bar which is con- 

 nected by a leather strap to the frame work. The motion of the shaker gives an 

 up and down motion to the fingers. The grain on leaving the cylinder passes to a 

 beater, which throws it up on the upper shaker, from whence it is taken up by the 

 fingers and so thoroughly shaken as to completely separate the%rain from the 

 straw. This machine has clover huller attachment ranking well up among machines 

 of that class.
