The present case is'a division of our copend
ing application Serial No. 756,794, filed Decem
ber 10, 1934.
‘
The invention is illustrated herein as applied
to an off-set press wherein the’frame of the press
comprises side members I 0 and tie rods II._~ In
the printing couple illustrated there are three
parallel shafts I2, I3 and I4 upon which are ro
tatably mounted a plate cylinder I5, a blanket
cylinder I6, and an impression cylinder Il. 'I‘here
45 is also a delivery cylinder I8 mounted upon a
shaft I9.
20 is a power shaft carrying a belt pulley 2|
which may be driven from any convenient source
' of power. On the shaft 20 there is a'pinion 22
50 which meshes with a gear 23 on a short shaft
24 that'carries a pinion 25 on its inner end. Pin
ion 25 meshes with a gear 26 on blanket cylin
der I6. Cylinders I5 and I'I are driven from
gear 26 through a gear 21 on cylinder I5 and
55 a similar gear, not shown. on cylinder I1.
centrics are keyed to the shaft so that they both .10.
turn together and to the sam‘e extent.
Conse- v
quently they may be actuated from one end of
the cylinder only. One such eccentric is illus
trated at 28’in the drawings. .To it is attached
a crank 29.
'
_
On the end of crank 29 there is mounted a
noddle pin 30 which is perforated to receive the.
end of' a short connecting rod 3|, the lower end
of which is formed with an eye which surrounds
a pin 32 mounted in a bell crank lever 33 which 20
is pivoted to the frame at 34. `'I'he lever 33 is
provided with two adjustable studs 35 and 3B
which are adapted to engage with stop blocks 31
and 38 respectively on the frame of the machine,
thereby limiting the movement of the' lever in 25
either direction.
'
The right-hand end of lever 33, as viewedI in
Figs. 1 and 3, is formed with a slot' 39 which re
ceives a pin 40 that is mounted in a lever 4I ,
which pivots upon a pin 50 s_et into the frame I0. 30
The lever 4I is also provided -with two forwardly
projecting pins 5I and 52. These latter pins are
adapted to be engaged on their lower sides by
.shoulders on the opposite lsides of a plunger 53
which carries a roller follower on its lower end. 35
This follower runs upon a cam 54 which is
pinned to shaft I9.
_
Pivotally connected with the plunger 53 is a
trip rod 5l which may be automatically oper
ated in connection with the sheet feeding mecha 40
nism of the press, or manually operated. It is
shown in Fig..1 in the normal'running position.
In order to guide the lower end of plunger 53
and in order to provide pressure to hold the - -
plunger follower against the surface of c-am 54, 45
we mount the lower end of the plunger upon a
pivot 58 carried by the bifurcated end of a bell
crank lever 59 which is pivotally mounted upon
the frame at 60. Within the bifurcated extremity
of the other end of lever 59 we pivot a rod 6I 50
which is slidably mounted in a perforated ear
62 projecting from the frame I0. A coil spring
63 surrounds the rod 6I between the ear 62 and
adjusting nuts 6,4 threadably mounted on the rod.
Spring 63 therefore tends to lower pivot pin 58.

lNow, assuming that the sheet feeding means
' of the press is provided with an automatic trip
mechanism, then when there is an interruption
to thefeeding of the sheets the rod 51 moves to
ward the left from the position illustrated in Fig.
1, throwing the plunger 53 against the side of
pin 5|.. As the high spot of cam 54 raises plunger
53 the shoulder on the left of the plunger en
there is pinned a hand crank I85 by means of
which the shaft may be turned from one extremev
position, illustrated in Fig. l, through an inter
mediate position, illustrated in Fig. 3, where the
springs |8| are free to act, and toits other ex- l
treme position, illustrated in Fig. 4, where the
frame 98 is separated entirely from frame 88 and
raised high enough to expose form rollers 81, 88
gages pin 5| and pushes it upward, thereby swing _ and 89 for removal and replacement. It will be 10
.10 ing the lever 4| from the position of Fig. 1 to that " noted that in Fig. «1 the pivot point |83 is` overv
center in one direction, while in Fig. 4 it is
of Fig. 3. Lever 33 is thereby swung to the posi
tion of Fig. 3, pulling downwardly upon the outer 'over center in the other direction. Hence when
lend of crank 29, and imparting a slight clock
\wise rotation to eccentric 28, which moves the
15 shaft I3 sufficiently to throw cylinder I8 out
of contact with cylinders I5 and |1.
.The inker includes a_lower frame 88, which
comprises two independent side members. This
either one of these positions has'been assumed,
the parts tend to remain in that position.
An adjustable screw |88 mounted in one of the
connecting rods |82 engages the shaft |84 and
limits the downward movement of rods |82 and
the clockwise movement of crank I85. An ad
justable screw |81 carried by the main frame
frame is pivotally mounted at one end upon a
20 short shaft 8| which is fixed in an upwardly pro i i8 engages a projection |88 on the crank I85
jecting part of the frame I8, and at the other
upon a sleeve 82 mounted in the frame surround
and limits the upward travel of frame 98, as in
dicated in Fig. 4.
It is desirable that the form rollers 81,88 and
89 be lifted out of engagement with cylinder I5
whenever the feed of paper sheets is interrupted,
and to this end we provide means for vshifting'
crank |85 from the position of Fig. 1` to that of
ing 'a short shaft 83, to which reference will be
>made again hereinafter. The two shafts 8| and
25 83 are, of course, in alignment. 'I‘his frame 88
has brackets 84, 85 and 88 in which are rotatably
mounted form rollers 81, 88 and 89 respectively,
which run upon plate cylinder |5 in the normal ' Fig. 3 whenever the throw-ofi? for blanket cylin
der I6 is operated. This means consists of a rod
