spring-‘operated means to advance said star wheel
During the completion of the advance move
ment or the star wheel, the engaged point of the
star wheel is moved beyond the projection 85, and
the ?exible arm 38 then swings upward, separat
ing the terminals 33 and I! and breaking the cir
cuit, the parts being then in the position shown in
Fig. 5. During the time the circuit was closed,
the-solenoid coil 23 was energized and a blow was
struck by the hammer ll.
When the pressure of the card is removed, the
spring 80 restores the bell ‘crank 30 to initial posi_
tion and moves the latch 10 to the right to clear
the pin .18 and to reengage the lower end oi the
feed lever 54.
.
_ It thus appears that the operation of the ham~
mer mechanism is initiated by insertion of a card
in‘ the card chute and by pressure of the card
- against the o?'set portion 32 of the bell crank 30.
It further appears that the simple downward dis
placement oi said bell crank causes successive cir
cuit-closing and circuit-breaking operations to
take place which are entirely independent 01’ the
operation 01' any other part of the machine.
Ii’ for any reason the parts operated by the
electro-magnet or solenoid should fail to move,
this would have no effect on the closing and open
qing of the circuit, which events would take place
in definite timed relation and regardless of the
movement or lack of movement of any other ma
chine part.
While I have shown my invention embodied in
a machine in which a movable card support is
utilized, it is obvious that my improvements would
operate in the same manner in a machine in
which the card support was stationary.
Having thus described my invention and the
advantages thereof, I do not wish to be limited to
the details herein disclosed, otherwise than as set
18 iorth in the claims, but what I claim is:
