<;ouie in from either side, to supply tlie blast, from interfering with each other, and

The ventilator is intended to be used wherever it may be desirable to produce a 

 current of air for any purpose, such as ventilating mines, hospitals, etc. It will 

 force a current of air against a pressure of one-fourth pound to the square inch- 

 It may be placed in any position, and piped to any place ; is simple in construction, 

 iiind requires very little power to run it. 



Clover Hiiller, by Birdsall Mannfg Co., South Bend, hid. This is an improved 

 machine, known as their "iVew Monitor Junior" clover huller. It has a new tail- 

 ings elevator, by means of which tailings are .sent directly to the hulling cylinder 

 without allowing them to be mixed again with the straw and chafl', as they would 

 be if returned to the threshing cylinder as is generally done, and thus having to do 

 over again what has once been done. This improvement greatly increases the 

 capacity of the machine. The machine has also a re-cleaning attachment that 

 may be readily attached or detached from the machine, that cleans the seed per- 

 fectly, ready for market. It is provided with an undershot fan and an end-shake 

 shoe, having sieves of perforated zinc. The cleaned seed is delivered in one sack 

 and the tailings in another. The cylinder is undershot, with an adjustable con- 

 cave in three sections, and suitable blanks are provided to put in place of such sec- 

 tions with teeth, as may not be needed in threshing dry clover. The hulling is 

 <lone with a cylinder and concave that are covered with tempered steel rasps, that 

 -tre claimed to do this difficult work in the best possible manner.
