BLOWER OR PNEUMATIC ELEVATORS. 181 



of throat), and equipped with metal bucket elevators or blower 

 elevators as desired, adaptcible to any height of silo. The blower 

 machines require more power to operate successfully than do the 

 carrier machines, although the largest sizes can be run by an 

 ordinary threshing engine. The traveling feed table and the bull 

 dog grip feed rolls are valuable features and practically do away 

 with the labor of feeding the heavy green corn, besides increasing 

 the capacity of the machines about one-third, on account of its- 

 being so much easier to get a large amount of material past the. 

 feed rolls. These machines have been on the market for upwards 

 of twenty- five years, and have been brought to a wonderful state 

 of perfection. For durability, ease and reliability of operation, 

 capacity and general utility, they are doubtless the most practical 

 means of filling the silo. 



The Metal Bucket Elevator is the older style of elevator. It 

 delivers the cut silage corn into the silo through a window or 

 opening at the top and must be longer than the silo is high as 

 it is necessary to run the carrier at somewhat of an angle. The 

 length of the carrier required may be obtained by adding about 40 

 per cent, to the perpendicular height from the ground to the win- 

 dow; thus for a 20 ft. silo a 28 ft. carrier is required, and for a 

 30 ft. silo, about 42 ft. of carrier will be necessary. 



The Metal Bucket Elevators for Silver's "Ohio" Silage Cutters 

 are made both straight away and with swivel base, which en- 

 ables the operator to set the cutter in the desired position, and 

 as the swivel base gives the carrier a range of adjustment ex- 

 tending over nearly a half circle, the carrier can be run directly 

 to the window, or in the case of two silos setting side by side, 

 both can be filled with one setting of the cutter. 



The Nos. 15, 17 and 19 Silver's "Ohio" Silage Cutters are the 

 sizes most in use by farmers, stockmen and dairymen. The 

 traveling feed table, first adopted by the "Ohio," which is long 

 enough to receive a bundle of corn is a most valuable feature 

 and has become almost universal on the "Ohio" machines used 

 for silo filling. It decreases the labor of feeding and makes any 

 size of machine about equal in capacity to the next size larger 

 without it. 



The newer and more modern method of elevating fodder in 

 filling silos, is the use of the Blower Elevator which blows the
