of the four type beds I3, the cams I0 being ar
ranged to rise successively so that only one of
the type beds prints at a time.

Rollers 68 are geared together and turn at the

these rollers is engaged by smaller rollers 61
(Figs. 4 and 5), which are mounted on frame 10

For example, for every sixteenth of an inch
in circumference of the top and bottom feed roll
ers 88 and 81 heretofore described, there is a
tooth on the ratchet-wheel 92. Ratchet-wheel 92
is mounted at the front of the machine on the
same shaft 93 with the bottom feed roller 81.
The feed rollers 81 and 88 are six inches in cir
cumference. Thus there are ninety-six teeth in
the ratchet wheel 92. For every tooth in the
ratchet-wheel 92 the pawl 94 passes over on its
counter-clockwise movement, ile of an inch of
paper' will be fed by rollers 88 and 81 when pawl

A spring-actuated pawl 94 engages the ratchet

‘ Referring to Figs. 27, 28, 29 and 31, there is a
perforating wheel 8| which perforates the paper
longitudinally. This wheel (or wheels) is mounted
on an adjustable arm 8|a which is attached to
a collar and arm member ßlb, and is, in'turn,
mounted on a shaft 8|c. Shaft 8|c has a down
turned arm 8|d, as shown in Fig. 29. At the end
of this arm 8|d is an attached spring 8|e. Spring
8|e in turn is attached to the end of a threaded
bolt 8| f which is supported by an eye bolt 8|g.
The function of the arm 8 Id, spring Sie and bolt
8|f, is to maintain the proper tension of the per
forating wheel (wheels) 8| against the paper and
the roller 81, as shown in Figs. 27 and 28.
