Pendulum Clock.
THE AMERICAN INSTITUTES FAIR-Havng visited the

nents age 10 which would direct the particular
,sutien Of yise.s. Cranes Patent Twelve Month
Clock aud large time piece for Banks &c. They beau
uu well finished articles and if required may be made
10 years with winding, well one and
feel confirmed in the impression (rom careful eyamnaton
that they destined supersede all other Clocks and time
keepers in in fact the approach oper
peual motion that have seen requiring motive power
equal TO only pounds Of weight for year.
The great Improvement in the Time Part consists prin-
cpaly in the Escapement which may be called Friction
less Escapemen, and in the Regulating Notion which may
be called Rotary Torson Pendulum. The Ball four
and half inches i'll diameterof globular form and ho
low and suspended by steel spring. the upper enc Of
the spring in the form Of Crank; the revolving
Of the ball the spring and the form
arc acting upon and receiving the impulse from the Swing
Wheel by Of lever connected with the Arm and the
Pallets or Escapement; which impulse is carried through
the Spring the Ball. and keeps motion. The spring
ia quescent longest; BY its being twisted either
way from that shortened and the ball made rise
returning by the reaction Of the spring, and the force Of
gravity receiving the impulse from the mantaing power q;
each return.
There is eguarity existing IL the common Pendu
m BY loss Of power arising from increase Of friction,
thereby esenng the impulse given it, and shortening the
Of its vibrations. If it time in of
four degrees will gain seconds day by vibrating IN
Of three degrees that by increase of friction
and loss Of power which always the case it will gain

Any difference of friction or maintaining power This
Clock, will aec, the time gwen by this Penduum It's
revolutions vibrations rendered perfectly sochrna
by the influence that the ,orson Of the spring has IN lis re-
action upon the force gravity OF the ball The different
degrees Of temperature affect the time given by this
pendulum The time would lose b. the expansion of the
spring length, accurately counteracted by the time 1t
gains by its expansion width and thickness and the time
woud BY the expansion Of the ball outward from its
axis Of notion accurately counteraced and compensated
for BY an adjustment inside the ball The improvement IN
the striking part consists principally in the application Of
Rotary Hammer Each part of this Clock is driven by
spring equal to seven pounds Of weight for about fyour
