Practical operation
In the operation of my counter the knob 3i
may be depressed from the position of Fig. 2 for
running up one digit at a time on the indicia
carrying element A1 and through proper coopera
tion of the pawls IS in a known manner, the in
dicia carrying elements A2 and A3 are moved one
space in ten and one space in one hundred, re
spectively. When the knob is released, the spring
32 returns the knob for another counting opera
tion when the knob is again depressed. During
the return movement the holding pawls I'I pre
vent return rotation of the indicia carrying ele
ments, there being one pawl for each element.
The knob 3| may be depressed any number of
times and when it is desirable to return the
counter to zero all of the indicia carrying elements
A1, A2 and A3 may be simultaneously moved in a
may be quickly returned to zero position by a
single motion of the lever 36 through about a
half revolution. When the lever is permitted to
return, the sectors are free to move to their initial
positions without catching on the gear elements,
as the missing tooth of each gear element at that
time is at the position shown in Fig. 3, where the
sector teeth cannot mesh with the gear teeth.
Finally, when the lever 36 strikes the stop pin 31
the counter may be operated again, with assur
ance that it will be started with all indicia carry
ing elements at zero.
Some changes may be made in the construction
and arrangement of the parts of my device with~
out departing from the real spirit and purpose of
my invention, and it is my intention to cover by
my claims any modi?ed forms of structure or use
of mechanical equivalents which may be reason
ably included within their scope.
