180 MECHANICS. 



rington, of Worcester, Mass., is an excellent hay-knife, 

 when folded, as in fig. 205, and an efficient elevator, when 

 opened, as in fig. 204. It is well adapted to the use of 

 farmers who have nothing but hay to pitch, and plenty of 

 room for the elevator to swing in. At the Auburn trial, 

 this fork discharged a load of hay weighing twenty-three 

 hundred pounds, over a beam, in two minutes. 



The prices of horse-forks, of different kinds, vary from 

 $10 to $20. 



HAT CARRIERS. 



An inconvenience results from the fixed position of a 

 hay-fork, preventing the hay from being distributed over 

 different parts of a broad bay, except so far as it may be 

 swung to the right or left, and the load dropped at a sig- 

 nal Several hands are sometimes required to spread this 

 hay evenly, as it is rapidly discharged by the horse-fork. 

 Another disadvantage is, the required narrowness of the 

 bay, which cannot well be more than twenty or twenty- 

 five feet wide. These objections are obviated, and the 

 hay carried fifty or a hundred feet horizontally, by means 

 of Side's Elevator and Carrier^ of which the following 

 clear and full description is given in the Report of the 

 Auburn Trial of Implements : " It consists of a track, 

 made of 2 by 5-inch plank, fastened to the rafters a few 

 inches below the ridge of the barn by l^inch square 

 strips and twelve-penny nails. Upon this track runs a 

 car ; a rope passes through it, and through a catch pulley 

 attached to a horse hay-fork, then back to the car ; the 

 other end passes back to the end of the barn, and returns 

 through pulley wheels to the bam floor, to which end a 

 horse is attached. 



By a peculiar arrangement of the car, it is held in posi- 

 tion on the track, over the load to be unloaded, until a 

 forkful of hay is elevated to it, when it is liberated from
