This invention relates to sheet handling appa

apparatus for use with a press or the like to
handle sheets relatively thereto. While in its
broadest aspects the invention is applicable to
sheet handling apparatus generally it is in cer
tain respects especially applicable to sheet deliv

or the like. This application is a division of my

U11 of the eccentric |01 is generally to the left of the
gated slot 91 in its opposite end. A stub shaft
98 is mounted in the delivery and has a bell crank
lever 99 turnably mounted thereon. The bell
crank lever has a generally downwardly extend
ing arm |00 having at its extremity a pin |0I
which enters the elongated slot 91 in the link 96.
The bell crank lever 99 also has a generally lat
erally extending arm ‘|02 to which is pivoted at

As explained above in
connection with the delivery driving mechanism,
when the delivery is to be moved away from the
press the handle 90 is turned through two revolu
tions in the counter-clockwise direction viewing
Figure 1 and this turning of the handle is accom
panied by rotation of the shaft 92 to a limited
extent inthe clockwise direction. Such clock
wise turning ci the shaft 92 swings the eccentric
upwardly and toward the right viewing Figure 1.
But since the fulcrum pin »I || is stationary such
swinging `of the eccentric causes the arm |09 to

‘ shown in Figure 1. This lowers the link 11 to ap- i
proximately the orientation shown in Figure 1
but as thus lowered the hook 18 is not engaged
over the crosshead pin 88. Upon movement of
the delivery toward the press the inclined nose
surface |06 of the link 11 rides up on the cross
head pin 8B, thus raising the right-hand end of
the link 11 about its pivot 16. As the delivery
continues movement toward the press the right
hand end of the link 11v is progressively raised
until the hook 18 finally drops down over the
crosshead pin 88. This movement of the link 11
is permitted by reason of the provision 'of
the elongated slot 91 in the link 96, for when
the right-hand end of the link 11 is raised by
engagement of the inclined nose surface |06
with the crosshead pin 88 this pushes up the
rod I 04 and turns the bell crank lever 99 to y
direction ‘ somewhat less than two complete
revolutions. This, as above explained, is accom
panied by turning of the shaft 92 and movement
of kthe center of the eccentric |01 generally up-,
wardly and toward the right viewing Figure l.
But the lateral component of such movement
moves the arm |99 as a whole to the right suiii
ciently for the latch Il@ to clear the plate H6
and when this has occurred the spring | I3 pulls
up the latch into latching engagement with the
plate H6. The handle 99 is then turned back
in the Aclockwise direction to the position Vshown
' in Figure 1, which swings the eccentric |01 down
wardly and toward the left. This tends to move e
the arm |09 to the left, but since the opposite end
of the arm is firmly hooked or latched to the
press the result is‘that during such clockwise
turning ,of the handle 90 the delivery is by the
arm |99 through the eccentric |01 drawn up

of the delivery, the two arms being identical and

by slight up and down movement of the rod i
operating synchronously. This causes the deliv

allows the pin I0| to ride freely therein during
ery and press to be drawn together firmly adl
such movement.
Fixed to the shaft 92 is aneccentric |01. Sur

It has been explained above that operation of
the motor 25 in one direction or the other causes
rotation ofthe screws I6 and i8 to move the
delivery toward or from the press. The motor
circuit is controlled by four switches, one for
closing the circuit to start the motor in one di
rection to move the delivery out, a second for
opening such circuit to stop outward movement
of the delivery, a third for closing the `circuit
to start the motor in the reverse direction to
move the delivery in, and a fourth for opening

such circuit to stop inward movement of the de
livery. The delivery being in the out position,
the handle 39 is tur-ned in the clockwise direc
tion to the position of Figure 1. Fixed to the

is a gear |23 and another gear |30. The gear
|30 meshes with a pinion l3| ñxed to a shaft
|32. Also fixed to the shaft |32 is a pair of
sprockets |33, one adjacent each side frame.
Carried by each of the side frames of the delivery
is a stud |34. Each stud |34 carries interiorly of
which closes the motor circuit to operate the

motor in the direction to cause the delivery to

is mounted on the frame of the delivery adjacent
chain |36 at each side of the delivery meshes
shaft 32 is a pair of switch operating arms H6
and H9. When the handle 30 is moved as above
described the arm H8 operates a switch |20
the shaft 92 and in position to be operated by
the arm llS upon movement of the handle 90
as just explained.
The delivery continues its
inward movement until a switch operating mem
ber l2! on the press operates a switch |22 on the
delivery which opens said motor circuit and stops
inward movement of the delivery toward the
press. The switch |22 and switch operating
member |2| are so positioned that the switch
|22 is operated to stop the delivery a fraction
of an inch before it reaches its fully operative
position adjacent the press as above explained.
Thereafter manipulation of the handle 96 as
above explained draws the delivery up tight
against the press.
When the delivery is to be moved out away
from the press the handle 9|] is turned two revolu
tions in the counterclockwise direction viewing
Figure 1. This causes the switch operating arm
H9 to swing upwardly and operate a switch |23
carried by the delivery adjacent the shaft 92 to
close the circuit which operates the motor in the
direction oposite that in which the delivery is
moved in toward the press. Consequently the
delivery moves outwardly away from the press.
This movement, as above explained, is accom
panied by downward movement of the link 61.
Such link carries a switch operating arm |24,
which when the delivery has reached its full out
ward position operates a switch |25 carried by
the delivery adjacent the link G1. Operation of
the switch |25 opens the circuit and the deliv
ery stops.
The handle 50 controls the motor for moving
the delivery, the driving connection between the
delivery and press and the mechanical connec
tion or latch for holding the delivery in place
against the press. When the delivery is in, as
shown in Figure 1, turning of the handle 9|)
through two revolutions in the counter-clockwise
direction releases the latch lill, disconnects the
driving connection 18 and iinally initiates oper
ation of the motor to move the delivery out.
The handle 96 also initiates operation of the
motor to move the delivery in and positions the
arm |69 and the link 11 to adapt them to co
with one of the sprockets |33 and the aligned
sprocket |35'. Each of the sprocket chains |36
passes over idler sprockets |31, one or both of
15 which may be adjusted for tensioning the chain.
Each of the sprocket chains |36 has one or
more special links, the special links in the re
spective chains being positioned opposite each
other. Each of such special links has connected
20. thereto a bracket, the opposed brackets being
connected by cross members to form a carriage
22,2 oscillatable in the horizontal direction view
ing Figure 1. The structure of the carriage and
the means for supporting and guiding it form
25 no part of the present invention and are not
shown and described in detail. The oscillatory
movement of the segment |25 is transferred
through the gear |21, the shaft |28, the gear
|30, the pinion |3|, the shaft |32 and the sprock
30 ets |33 to the sprocket chains |35 and thence
to the carriage itself. Thus during operation of
the mechanism the reciprocable delivery carriage
moves back and forth longitudinally of the de
livery and toward and from the press.
The car
35 riage carries sheet handling means including
tapes |44 cooperating with the tapes 6l] and 62
to receive and deliver sheets, but since such
means form no part of the present invention
they will not be described in detail. Sufiice it
to say that the recîprocable delivery carriage
ordinarily receives a sheet from the tapes 60 and
52 upon each reciprocation thereof and delivers
the. same to the delivery pile.
Meshing with the gear |29 is a segment |45
45 ñxed to a sleeve |46. The sleeve |46 is jour
naled for angular oscillation upon a shaft |41.
The sleeve |46 passes through the delivery side
frame as Shown in Figure 3 and carries at its
outer end an arm |43. Since the segment |45
50 and the arm |48 are both i'ixed to the sleeve |46
they are to all intents and purposes unitary.
The arm |48 carries a pawl |49 projecting later
ally therefrom and engaging a ratchet |56 ñxed
to the shaft |41. The pawl is normally resil
55 iently urged into engagement with the ratchet
|50 by a coil spring l5l. Upon oscillation of the
segment |45 the paw1 |49 advances the ratchet
