LovEJoyfs ANrEFH1cTIoN CelToS PREss. This
Is certainly So age Of progress in the line Of ma
chimney Necessity Is commonly said to be the
smotheF If invention, but II seems to US that the
3y,s nf getting valuable patent right Is the pa
rent of ar more important efforts of invention than
S1sFe necessity essr brought to Light Among the
matt perfect Inventions that We haveseen for some
fisue must be ranked the new cotton press resl
fsrrea u shows, and which was exhibited inopera-
ton yesterday afternoon, BIZ Messrs .. !. Spear n
0. q vacant lot near the corner Of Poydras and
jRaropne streets. In little over one complete
tarn Of the main lever, bale Of cotton weighing
between 5l0 ana 900 pounds was compressed from
II Ia " inclea, that IA 10 inches. 1t was in fact
e1mpressed d great deal more than would be ne
eessary on plantation, as the bales have to 60
through the steam press at any rate. This was
done too without horse mnle power, but BY three
III fonr men Ut each end OF the lever without appa-
eslsly nEcll eif9ft ontheir part.
IS Tile greet advantages OF this invention seems to
he saving In power, with an immense increase Of
speed. Two revolutions are sufficient with this
pres, whie with HE screw press eighteen to
twenty are generally required 10 each bale. AT
that ratio the Number turned out in the same
length Of time will be eight or ten Of the former
fhatit would never be necessary to use more than
ane gcod mule for turning the press, while in the
screw press, two, four and even six, are sometimes
used, s'hs rapidity of revolutions by this system
ii greatly increased tor a. the lever IS, we think
eniy fifteen feet, while that Of other presses il
generally about thirty.
The superiority Of this invention consists prin-
eipnlly 10 its avoiding nearly all the friction
of the old system, and consequently, immense
waste Of power. Instead Of tie cottons being
compressed BY tile screw, the pressure il err
Eectea BY leverage. The g follower Or plat.
form which acts Immediately on the cotton,
isseohnected with the upper beam by two dou-
Bile levers. These double lovers are iointed in
He middle - TINT when the q follewert, Il lift
ed DIP these joints defect outward as far from
one another Obj possible. As the follower n do
acends these joints approach one another until a
its greatest point of descent, both doubb lever
are straigh nearly SOL and parallel. The appli
cation 81 the power Is npon these joints ID sucl
way as 10 force them towards each other, thus fore
ing tie follower downward and compressor,
the cotton,
Another advantage consists in the fact that iii,
application OF power Is equaiized; that IL, pary
little more j. required at tile end than at com
lnencrment Of comprising q bale. This is owing
70 the fact that, The . follower il moved NOR,
slowly BIZ the levers the nearer they come to beins
stxaiehter, and that, BY an ingenious contriyance
the power itself Is applied In diminishing ratio
while the gait Of the mule is The same. 4.
We understand that the right for selling these
machines IN some Of the Atlantic States has al
ready been sold for handsome sum, and canno
doubt that the inventor viii fare as well among
onr planters Messrs. 7. ]. Spear q co. give
another public exhibition of This press ut the SAINT
place, Tomorrow afternoon at o'clock.
