SPECIAL MERITS OF EXHIBITS. 171 



The Case & Willard Manufacturing Company, of Battle Creek, i^fi'cA., exhibited one 

 of their Advance separators. This machine has some points worthy of especial 

 note. It embraces a combination of principles somewhat different from any other 

 machine on exhibition at the Indiana State Fair this year. The cylinder is 

 about one foot nearer the ground than in the average of threshers, thus affording 

 the convenience of lower tables. The cylinder has two center supports for the bars. 

 The heads are solid. The shaft is of steel, one and three-fourths inches in diame- 

 ter. The teeth are made of steel. The sides of the cylinder frame are of iron. 

 The separator being wider than the length of cylinder enables all pulleys for belts 

 on the cylinder shaft to be on one end. The pulleys for the main belt to the en- 

 gine run inside of the yoke and box. This yoke is bolted to the posts. The belts 

 which drive the separator are outside of the yoke and box and close to the side of 

 the machine. This novel arrangement of the belts, pulling in opposite directions, 

 saves a large amount of friction on the bearings and boxes of the cylinder shaft. 

 By a simple device botli ends of the concave are raised and lowered at the same 

 time by one motion. This machine has folding tables, which are not removed 

 when moving the machine from place to place. The cylinder teeth, instead of be- 

 ing at right angles with bar, are bent at the shoulder so that they incline back- 

 ward, thus tending, it is claimed, to feed easily without bunching or choking. The 

 machine is strong, steady and durable, possessing a wonderful capacity for rapid 

 and efficient work. 



The Springfield Engine and Thresher Co., of Springfield, , exhibit one of their 

 "New Springfield" separators. Thjs is a beautiful machine of superior symmetry 

 and workmanship. AVhile upon general principles it has justly merited a place 

 among first-class threshers, it has some points worthy of special mention. It has 

 straw rakes of positive motion. The rakes are thrown down with the same speed 

 as they are thrown up, striking the straw again before it reaches the pan. One- 

 half the straw has an upward motion while dne-half has a downward motion, by 

 which means the grain is thoroughly sei)arated from the straw. No cog wheels or 

 pinions are used on the machine. The concave adjuster is positive both ways. 



Roberts^ & Thorpe, of Three Rivent, Mich., by C. E. Merrifield, Indianapolis, Ind., 

 exhibit one of their "Invincible" threshers. This machine is of extra length and 

 width, affording a broad surface for separating and cleaning. It is claimed for the 

 "Invincible" that it is light running, easily operated and very durable. The 

 beater is placed a little in rear oi the cylinder and so near to it that the straw is 

 closely combed from it — leaving little chance for straw to choke or wind around 

 the cylinder. The alternate motion of sheet iron shaking pans, operated by double 

 pitmaus, not only produce a counterbalance, but hurries the separated grain rear- 

 ward towards the shoe. This separator is built diverging from the cylinder to the 

 discharge end, so that by thus gradually widening the separator a greatly increased 

 separating capacity is given. The cylinder is constructed with heavy cast heads 

 and wrought iron bars, twelve in number. The concave is made in three sections 

 and i8.adjustable from front or rear, and is perforated, the holes distributed in such 

 a manner that a large amount of grain passes through and is separated at once.
