C. Fig. 4. Shows the frame through which the knives with their frame Hide,, 

 grooves being made in the fides, a a, to receive the fame. The circular part at 

 top, marked c t is bent back (as may be feen) in the fection B, to make room for 

 the nut and fere w which fallen the handle to the knife- frame. This frame is faf- 

 tened to the bottom, dd t by cheeks, as may be feen in the plan A. In the fectiorv 

 of the bottom d d, are (hewn the holes through which the fmall knives pafs. 



D. Fig. 5. The cutting knives and frame: a t the great knife which, when in 

 action, finks into the long groove up to the fhouldcrs, bb\ cc c t the fmall knives- 

 which are fixed at right angles, with the large one, the tops of which are ri- 

 vetted into the large knife ; the lower ends of the fame are kept at equal dif- 

 tances, by being let through a fmall bar, and fattened with a nut, a worm being 

 made at the end of the knives. The frame which carries thefe knives is fattened 

 only to the great knife, b b: d, a hole in the frame to fatten the handle to. The 

 fides, f e&amp;gt; have a worm at the bottom, by which the bar /is faftened to the fame 

 with nuts : g the fwivel for the treadle bar : b b the guides for the brafs wheels to the 

 fpring. It will appear that the great knife being faftened to the frame, the fmall 

 knives will neceffarily project before the fame. 



E. Fig. 6. The handle and guide to the fame : at a the handle is fixed with a 

 fcrcw-bolt and nut to the knife-frame, fo as to move eafily : b, a brafs wheel fixed 

 in an iron ftrap fcrewed to the machine, fo contrived that the end of the handle 

 will pafs through an opening below the wheel, the ufc of which is to act as a reft 

 to the extremity of the handle, and to prevent friction, its fituation varying confi- 

 derably with the motion of the knife-frame. 



F. Fig. 7. Plan of the iron fpring which raifes the knives, made two inches 

 wide at one end and about one at the other, and a quarter of an inch thick, faftened 

 at the end with a nut and afcrewto the bottom of the trough with a ftrap near the 

 end. 



G. Fig. 8. Plan of the fpout. 



The turnips, when fmall, are put to the knives by a piece of board, the 

 length of the knives, about four inches broad, with a handle at the back. Great 

 turnips may be put to the knives, without this inftrument, but in fmall ones there 

 is danger of cutting the fingers. The machine will cut turnips into pieces *. inch 

 by .3. fquare ; and, of courfe, (if the turnip be large enough) 4*. long.
