CHAPTER XLIII 

 PORTABLE FARM ELEVATORS 



The Portable Elevator. One of the most recent machines 

 which has been developed to relieve the farmer of some of the 

 hardest work to be found upon the farm is the portable ele- 

 vator. Nothing is more tiring than shoveling corn into a 

 crib after husking all day. The shoveling of wheat and 

 other small grains into the granary at threshing time is like- 

 wise laborious. The portable elevator not only does away 

 with the hard work but also saves time and reduces the help 

 required, both of which are to be obtained only at a premium 

 during a rush season. A good elevator will do the work of 

 from two to five men. 



Besides saving labor, time, and men, the portable elevator 

 makes possible the construction of more economical cribs and 

 granaries. These can be built much higher, thus increasing 

 their capacity without increasing the cost of the roof or the 

 foundation. With elevators, one is not compelled to build 

 cribs or granaries on low foundations when wet ground 

 makes it undesirable. 



In general, the portable elevator outfit consists of a dump- 

 ing jack to lift the front wheels of the wagon and cause the 

 load to flow to the rear ; a hopper into which the load is fed ; an 

 inclined elevator with a chain carrier of flights or cups, which 

 carries the grain to the highest point in the crib; a spout or 

 conveyor to distribute the grain in the crib; and some source 

 of power, either horse power or engine. 



The Lifting Jack. The lifting jack is made in two styles, 

 the overhead and the low-down. The former has a yoke or
