NEW AND HIGHLY-IMPROVED HORSE POWER. 
NEW AND HIGHLY-IMPROVED IRON HORSE 
POWER. 
This power is compact, strong, and portable, 
and without bolts and joints, that are liable to 
work loose and get out of order. It is made 
on strictly scientific prin¬ 
ciples, and is so arrang¬ 
ed as to combine the 
least friction and great¬ 
est durability within the 
smallest compass. Five 
eights of the machine is 
firmly connected togeth¬ 
er, and not weakened by 
joints, and that on which 
the power of the horse 
is exerted constitutes 
three eights only; thus 
throwing the force more 
directly upon the work 
to be executed, instead 
of expending it in over¬ 
coming friction, produc¬ 
ed by complicated wood 
and iron frame work 
and cog wheels. In the 
gearing, great attention 
has been paid to prevent 
friction, by placing two 
pinions opposite each 
other and to the centre, 
thus creating a compen¬ 
sating force around the 
centre of motion, and at 
the same time preventing 
wear at the jounals and 
bearings. 
The horse power as 
seen in Fig. 53, will 
drive the centre, upright 
shaft 28 revolutions to 
one of the horse; and 
from this shaft, a strap 
is taken which drives a 
corn mill. On the same 
floor, a corn shelter is 
represented in motion, 
and on the ground floor 
we have a thresher, sep¬ 
arator, and grindstone 
driven by a shaft geared 
from the lower end of 
the upright shaft. This 
shows that a number of 
applications can be made 
from the same machine 
in one position. If it is 
required to thresh the 
grain in the field, it can 
be done without diffi¬ 
culty, and then replac¬ 
ing the horse power, as 
shown'in the cut, it can be used for shelling 
corn, ginning cotton, pumping water, sawing 
firewood, driving lathes, grinding flour, or saw¬ 
ing lumber. 
Four-horse powers are made on the same 
principle as the foregoing, and of an additional 
strength, proportioned to the increased power 
and train. Saw mills are made to accompany, 
and are driven by this power, which will saw 100 
feet of boards, joist, or plank per hour, from logs 
from one to two and a half feet in diameter. 
Overlimed Lands.— If a field has received an 
over dose of lime, add largely of putrescent, 
fresh vegetable and animal manures, or plow 7 
very deeply, or both. Land may thus be read¬ 
ily converted into an abundant and durable 
store house of fertility.
