Yol. I. ALBANY, FEBRUARY, 1853. No. II. 
EXTMA. 
The above engraving represents, partially, 
the invention of H. L. Emery, of this city, of 
a Reaping and Mowing Machine. 
Our columns are so crowded with other 
matter, and this description, promised in this 
number, we issue it as an extra in a form 
which can be preserved and bound with the 
work if desired. As only a portion of the en¬ 
gravings are yet completed, we cannot give it in 
full, until next number, and therefore only 
describe its main features, as it appears when 
arranged for cutting Grain. 
As will readily be seen, it is provided with 
a driver’s seat and wheels, independent of the 
machine itself, but attached by hinges in such 
a manner as to allow an easy action and ad¬ 
justment, while this method does away entire¬ 
ly with all the side draft. 
The machine itself is provided with a large 
main wheel, being about forty inches diameter 
and eight inches face,with the necessary projec¬ 
tions on its surface. This wheel is cast 
with an internal gearing at one side of the 
spokes, the teeth of which are protected from 
dirt and strengthened by a deep flange of 
nearly three inches. This flange is represented 
by that part of the cut bearing the- words 
“ Mower and Reaper, Combined .” The main 
frame is suspended from this wheel, by means 
of adjustable pinion boxes,the boxes being hung 
inside of hangers attached to the frame itself. By 
applying a kind of wrench to the box, (which 
projects far enough beyond the hangers, and is 
made square) it may be turned ; thus by the 
action of its teeth on the corresponding teeth 
on the hanger, the frame itself is raised or 
lowered to any desired point, where it is con¬ 
fined by a simple iron key. 
A small pinion is placed inside of this large 
wheel at the forward part, and its shaft 
confined to the under side of the frame it¬ 
self, this shaft extending far enough out-
