HAYING MACHINERY l8l 



teeth carrying the load are drawn up and over and the 

 load is thrown directly back upon the stack, the work 

 being done with a horse or a team of horses by means of 

 ropes and suitable pulleys (Fig. 134). 



The swinging stacker permits the load to be locked in 

 place after it has been raised from the ground to any 

 height and swung to one side over the stack. When over 

 the stack, the load may be dumped and the fork swung 

 back and lowered into place. The latter stackers are 

 very handy, as they may be used to load on to a wagon. 

 They have not as yet been built strong enough to stand 

 hard service. 



257. Forks. A cable outfit may be arranged with a 

 carrier and fork for field stacking, the cable being 

 stretched between poles and supported with guy ropes. 

 This outfit works the same as the barn tools to be de- 

 scribed later. Very high stacks may be built by this 

 method. 



A single inclined pole may be used in stacking by 

 raising the fork load to the top and swinging over the 

 stack. This is usually a home-made outfit, with the ex- 

 ception of fork and the pulleys.

258. Development. The introduction of the field hay- 

 ing tools created a demand for machinery for the unload- 

 ing of the load of hay at the barn, and this led to the 

 development of a line of carriers and forks, the first of 

 which was a harpoon fork, a patent for which was issued 

 to E. L. Walfer, September, 1864. In 1873 a Mr. Nellis 

 patented a locking device, which has given to this fork 

 the name of Nellis fork.
