128 Trials of Swath T'urners and Side Delivery Rakes. 
The lay shafts through the medium of which motion is 
transmitted to the sprocket wheels carrying the chains, are 
driven by right and left spur gearing, which, by means of two 
sliding clutches on the extension pieces of a counter shaft, are 
indirectly acted on by a foot lever, capable of being worked 
from the seat. This lever is connected to a rod, the forks of 
which engage with the clutches mentioned. By placing this 
lever in a central position the gearing is put out of motion and 
an ordinary fixed rake is obtained. By moving the lever side- 
ways one or other of the clutches engage, and motion is 
imparted to the chains, and from them to the teeth. 
Messrs. Martin’s 9 ft. machine was not brought out for trial. 
Of the three machines tried Messrs. Martin’s perhaps, on 
the whole, gathered the crop up best, but the same tendency 
to roll the crop as in the Swath Turners was very noticeable, 
and is undoubtedly a serious drawback. The draft of- these 
machines is light and the mechanism simple. 
The following two illustrations, which appeared in The 
Implement and Machinery Review, and the plates of which 
have been kindly lent by the publisher, Mr. Harry Westcott, 
illustrate very clearly the difference in the work done by the 
machines belonging to the different makers, and the rolling 
or roping of the crop by Messrs. Martin’s implement (to which 
the Judges took such exception) not only by the Side Delivery 
Rakes, but also by the Swath Turners exhibited by the same 
makers.
