end of the shaft 23 are located a cotter pin 42,
which extends transversely through the shaft

versely through the shaft 29. In order to increase
or decrease the tension of the spring 37 on the
rocker arm 32, the cotter pin 42 is removed and
the shaft 29 moved longitudinally a sufficient dis

the castellated collar 4%. The shaft 29 is then 35
rotated, by means of the pin 43, in the proper

A stroke limiting rod 44 (Figs. I andIII) is piv-v

the hollow interior of a vertically extending
threaded sleeve 45. The lower end of the rod 44
carries a washer 4B which engages with the lower
shoulders of the sleeve 45. The exterior of the
sleeve 45 is threaded and screwed into a horizon
tally extending ear 41 of the bracket 21. ‘Four
longitudinal serrations 48 are cut in the outer
surface of the sleeve 45 and are engageable by
a ‘manually movable latch 49 which is pivoted by
means of a pin 55 extending through the ear 41.

An escapement pawl 65 is rockably mounted on
a pin 5i and has two pointed arms 62 which are
alternately engageable with the teeth of the es
capement wheel 58. A counterweight 63 is at
tached to the escapement pawl 6%! to cause it
to rock with a pendulum-like motion. The es
capement mechanism just described serves as a
governor to prevent the return movement of the
segment gear 35 under impetus of the spring 31
from being abrupt or sudden.
The knurled feeding wheel 51 extends down
into a longitudinal opening in the upper wall of
a hollow paper guide. 84 which leads from a posi
tion in back of, and below, thev feeding wheel 51
to a position between the opposing faces of the
abutment l4 and platen frame !5. The periphery
of the feeding Wheel 51 is engaged with the up

through the ticket guide 54. A duplicate ticket
strip 65 also extends through the ticket guide
64 beneath the ticket strip 55.

through one arm of a bell crank 69 pivotally
