when it is desired to unload the fork. The double harpoon is much the 

 same except that it has two tines. Sometimes these are used in pairs, 

 making a four-tined fork. 



The Jackson patent or derrick fork has a triangular prone made of 

 wood with an iron bale hinged close to the piece which holds the tines, and 

 is secured to the vertex of the triangle by a clip while the load is being 

 raised. To unload the fork the clip is released by a rope from the 

 wagon and the tines turn back, allowing the hay to slide off. It has 

 four tines, which are set at right angles to the frame and curved 

 under it. 



The grapple fork is provided with tines which swing toward each 

 other like ice tongs, firmly gripping the hay. The tines are of various 

 lengths to suit conditions, and vary from four to eight in number. 



USES. The single harpoon is used in hay that is long and hangs to- 

 gether well. It is light and easily handled. The double harpoon is used 

 under much the same conditions, but will work in shorter and looser 

 hay. 



The Jackson fork is used in any kind of hay, and is an especial 

 favorite with threshermen in handling headed grain. It is simple and 

 easily handled with a little experience. The grapple fork is used in 

 short hay and the eight-tined forks are sometimes used to handle man- 

 ure. (See "Forks," in index.)
