NETlC TELEGRAPH.-Take two brass

rccesses, but secured in such a way as in nrc-
vent their falling out. These type will project
above the surface of each wheel, opposite the
pcriorations, are 10 be- inscribed the alphabet
-each letter to be written opposite the type
having the same letter on il. The two wheels
mus prepared are To be attached TO u motive
machine consisting oil ~cog-wheels, pinions.
drums, cords and weights, similar. to clock
work.
The lower half of each type wheel is i'm.
mersed IN and passes through a, cistern or
trough filled with a solution of the salts of
ifon.' Ohe OF these wheels, with it's motive
power apparatus and trough is placed at each
END OF the Telegraphic communication. the
centre OF each wheel being placed exactly
under the magnet, and one fourth of AN inch
rom 1t to permit the paper ribbon to pass
Dedween the wheel and magnet.
Inc sizing OF the paper is TO be intimately
mixed with a solution of g~all-nuts or tannin.
Inc Operators, by previous understanding.
oring the letter A to the apex of each wheel.
Immediately under the magnet. Both wheels
are put In motion at the same instant of time.
and the operator, conveying intelliuence
completes the current at the instant the letter
Is under the magnet that he desires To transfer
10 the under sides OF the paper ribbon as it
SLOWLY passes under the magnet and above the
whecl. The instant the current is complete
the iron bar becomes ii powerful magnet, and
causes the iron type under it To ascend and
stake the paper with a force equal to the in
'ensity OF the Electrical action. a touch. or
.ne slightest contact OF the type with the paper
Is sufficient to transfer an indelihle impress of
tte ietterto the paper, as the impression does

icai ac,iol, ;Iat part of the prepared paper
becoming black that was touched with type
wet with a solution of salts of iron.
In this way letters are formed on the prepa-
red ribbon; these letters form words, which
are separated from each other by the wheels
making a revolution between the end of one
WORD ana ao DE 6ofig55p peIaFTo Of n9thsf G5noys. Tho
TWO wheels are brought with letter A in the
apex. lhey are thus permitted TO r~evolve; as
'hc letters forming the words TO be printed
pass under the magnet, the current is connie
ted, winch causes the iron type TO ascend and
strike The paper TO which il transfers It's letter.
The opctator watches the wheels before him
and periecis the current the instant the letter
10 be transferred is under the magnet.
The sape letter is at the same instant of
time u%ndcfthe magnet at the opposite end of
the Telegraph.
The twolype wheels at both ends reyoly-
ing equal distances in equal times, bring the
same letter. under the influence of the magnet
at the sam5instant of time. Therefore. the
wheel attn operators end of the Telegraph is
a true md% OF the position of the wheel at
the opposit end. None of the type touch
the paper acept the current is complete. and
then the PIPER is alone touched bv the TYNE
f under the ,tgnet. Should it be desirable To
use igureshn addition to the Alphabet il is
only necessary to make the type wheels &c
, inches III circumference, and make 10 addi-
, tional per.rations into which 10 figures are
e placed. Rese can be acted upon as they pass
: under the magnet.
= 10 ne cmplcte success Of this Printing
Telegraph is Indispensable that the tyne
Y wheels revive through equal spaces at equal
, times.
This is Necessary to bring the same letter ON
both wheehmmediatcIy under the magnet at
, the same iktant of time.
