SCIENTIFIC MISCELLANY. 



RECENTLY PATENTED IMPROVEMENTS. 



J. C. HIGDON, M. E., KANSAS CITY, MO. 



Seeding Attachment for Corn-Drills. — This improvement consists in at- 

 taching to a corn or seed planter of any description a sprochet chain having re- 

 versible lugs pivoted longitudinally to each link or every alternate link, as may 

 be desired. 



The lugs are pivoted to project at a right angle from the length of the chain 

 links, and being reversible they may be thrown from one side to the other of the 

 chain, in or out of gear, with teeth projecting upon the circumference of the seed 

 plate, according to the distance apart it is desired to drop the seed. For instance, 

 to drop very close, all the lugs are thrown in gear with the seed-plate, and, on 

 the other hand, by reversing all of the lugs except one, seed may be planted such 

 a distance apart as corresponds with the full length of the chain ; while with a 

 common check-rower or listing-drill, owing to their faulty construction, dropping 

 can only be accomplished at comparatively shorter intervals. 



The chain links are preferably constructed of malleable iron, and of the 

 form previously described — that is, the lug-links have, near each end and projecting 

 from the side opposite the driving-wheels, ears or lugs, between which the main 

 lugs are pivoted. 



To prevent sagging it is preferable to provide a support for the chain near 

 the point where the lugs come in contact with the teeth of the seed-wheel, and 

 for this purpose an anti-friction roller may be used. 



This attachment may be arranged to operate any desired number of seed- 

 plates, so that several rows will be planted at a single operation. 



The inventor is Mr. Emile Lind, of Hiawatha, Kansas.
