Improvements in Sheet Delivering Mechanism for Printing
Machines.
I, ROBERT MIEHLE, of No. 1408 Addison Street, in the City of Chicago,
County of Cook and State of Illinois, United States of America, Machinist, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention relates more particularly to improvements in that class of sheet
delivery mechanism in which the sheet carrying fingers have a reciprocating
movement to and from the impression cylinder and are adapted to deliver the
sheet printed side up, and my invention has for its primary object to combine a
reciprocating delivery of this character with the ordinary fly delivery whereby the
two may be employed interchangeably and the conversion from one to the other
readily and quickly effected without entailing any appreciable loss of time.
Another object of my invention is to provide the reciprocating delivery with
improved means for receiving and holding the forward edge of the sheet without
pinching or marring the same, and which will prevent the sheets from riding the
wind and will ensure regular and uniform delivery thereof upon the piling table.
And a still further object of my invention is to provide means whereby ready
access to the inking rollers may be gained without the necessity of lifting the
entire reciprocating sheet delivery mechanism as heretofore.
With these ends in view my invention consists in certain features of novelty in
the construction, combination and arrangement of parts by which the said objects
and certain other objects hereinafter appearing are attained, all as fully described
in the specification, shown in the accompanying drawings and more particularly
pointed out in the claims.
In the said drawings

1 represents the feed table upon which the sheets are piled and from which they
are fed to the grippers 3 of the impression cylinder or device 4 which is mounted
as usual or in any suitable manner in the frame 5. The sheet 2 after being carried

page_text: around by the cylinder 4 and receiving the impression is released by the grippers 3
and is stripped from the cylinder 4 by means of the usual strippers 6 which project
into close propinquity to the periphery of the cylinder in the ordinary manner, and
these strippers 6 guide the sheet upon the usual tape rollers 7, 8 and conveying
tapes 9 which carry the sheet away from the cylinder 4 to a position immediately
over the fly fingers 10. These fly fingers 10 are mounted at their lower or but
ends upon a shaft 11 journaled in a portion 12 of the main frame and having
sleeved thereon a number of castings 13, each of which serves as a means of
attachment for one of the fly fingers 10 as will be understand. These fly fingers 10
descend between the tapes 9 and when in position to receive and carry the sheet
they are substantially horizontal and slightly below the plane of the tapes 9, as
shown clearly in Figure 4, and when conveying the sheet to the piling table 14
they make an upward sweep through an are of about 180 degrees as the shaft 11
is oscillated in the ordinary manner.
An oscillatory movement is imparted to the shaft 11 through the intermediary
of a reciprocating rack bar 15 which engages with the pinion 16 on the shaft 11
and which is itself reciprocated by means of a cam 17 arranged on a driving
shaft 18, and adapted to engage with a pivoted arm 19 having an anti-friction
roller 20 running against the surface of the cam, the arm 19 being pivoted or
otherwise secured to the rack bar 15 and the rack bar being returned and the
roller held normally in contact with the cam 17 by means of a spring 21 coiled
upon the bar 15 and bearing between a collar 22 on the bar 15 and a sleeve 23
pivoted at 24 and forming a housing for holding the rack bar in engagement with
the pinion 16, the sleeve 23 being provided with a guard 25 which surrounds the
pinion for preventing injury to the operator.
All these parts may be of the usual or any suitable construction, but it is
preferable to effect an operative connection between the rack bar 15 and the cam 17
by means substantially the equivalent of that described in order that the rack
bar 15 may be readily rendered inoperative and the fly fingers 10 held in a
substantially horizontal position below the plane of the conveying tapes 9 when it
is desired to deliver the sheets by the reciprocating delivery mechanism as before
intimated. When the construction for effecting this connection between the rack
bar 15 and the cam 17 which I have described, is employed, the fly delivery
mechanism may be readily thrown out of operation and the fly fingers held in the
described position by means of a lock consisting of an arm 26 pivoted at 27 to the
main frame and having a notched end 28 adapted to engage with the pivoted
arm 19 and hold the roller 20 out of the line of movement of the surface of the
cam 17.
29 and 30 represent two rails arranged in substantially a horizontal position one
on each side of the machine, and being pivoted at 31 to lugs or projections 32
formed on the main frame and being supported by the fly casting 32" or in any
suitable manner so as to project over each side of the piling table 14. These
rails 29-30 constitute the frame of the reciprocating sheet delivery, and they are
arranged at a sufficient distance apart to permit the fly fingers 10 to oscillate
between them and to deposit the sheet onto the piling table without interference.
Mounted upon the rail 29 on one side is a carriage 31 and on the rail 30 on the
other side a carriage 34. Each of these carriages is provided with anti-friction
rollers 35 at each end thereof whose peripheries are grooved or flauged and embrace
the upper edges of the rails 29-30, and thus serve to hold the carriage in place or
against lateral displacement while at the same time reducing the friction to the
minimum. The carriage 33 is provided with a depending arm or hanger 36 in the
lower end of which is pivoted a pin 37 provided with an eccentric enlargement 38
upon which is journaled a roller 39 which engages under the rail 29 and serves to
prevent the rollers 35 from leaving the rail, the portion 38 upon which the roller 39
is journaled being eccentric so that by the rotation of the pin 37 the roller 39 may
be adjusted with reference to the rail 29. In this manner provision is made for
taking up wear and bolding the carriage rollers firmly down against the rail. The

page_text: carriage 34 on the other side of the machine is likewise provided with a depending
arm or hanger 40 which carries a roller 41 having an eccentric journal (not shown)
similar to the journal 37-38 before described and for a similar purpose.
These hangers 36-40 are connected together by a transverse shaft 42 which is
securely bound at each end in the hangers 36-40 and normally held against
rotation by means of set screws 43 extending through the hangers 36-40 and
impinging the shaft 42. This shaft constitutes the means for supporting and
carrying the reciprocating sheet delivery fingers 44 which are arranged at suitable
intervals apart on the shaft 42, and which when in their normal position project
in substantially a horizontal direction between the fly fingers 10 and across the
upper side of the fly finger shaft 11 and are so disposed as to lie below the plane of
the upper fold of the conveying tapes 9; and their upper or right hand ends, as
viewed in Figure 1, are depressed below the fly fingers 10 when in the position
shown in Figure 1 ready to receive the sheet so that the fly fingers 10 will, in
conjunction with the tapes 9, constitute means for supporting the sheet and pre-
venting sagging thereof between the tapes while the reciprocating fingers 4+ are
moved toward and under the sheet, thus causing the fly fingers 10 to perform the
two-fold function of delivering the sheet when the fly delivery mechanism is in
operation and of serving to support the sheet preparatory to its reception by the
reciprocating fingers 44, when the reciprocating mechanism is operated and the fly
delivery mechanism is inactive.
The fingers 44 may be supported upon and secured to the shaft 42 in any suitable
manner, but I prefer to employ for this purpose a number of castings or hubs 45,
each provided with a set screw 46 whereby the hub may be secured against
rotation on the shaft, and each of these hubs is provided with an arm 47 to which
the finger 44 is attached.
Each of these hubs 45 is also provided with a projecting ledge 48, which virtually
constitutes a continuation of the finger 44 and upon which the sheet rests while
being carried by the reciprocating delivery. When the reciprocating fingers 44
are at the extremity of their return movement or in position to receive the sheet
they are in the position shown more clearly in Figures 1 and 4, and while in this
position the sheet is fed forward from the printing cylinder by the tapes 9 and is
pushed onto the ledges or projections 48 of the fingers 44, and in order that the
position of the sheet on the ledges 48 may be gauged and the sheet prevented from
being pushed at various distances beyond the ends of the ledges 48 the latter are
provided with a number of stops 49, which preferably project down over the extreme
ends of the ledges 48 so as to protect the edge of the sheet from the current of air
occasioned by the sheet moving forward on the carrying fingers 44; thus preventing
the edge of the sheet from riding the wind. This result is further prevented by
reason of the angular arrangement of the stops 49 with reference to the plane of
the projections 48 inasmuch as this arrangement constitutes a sharp, angle in which
the edge of the sheet is projected and held.
These stops 49 are mounted loosely upon a transverse shaft 50 which has its ends
supported in the carriage 33-34 and the stops are preferably independent of each
other and also independent of the shaft 50 so as to be capable of independent
rotation or oscillation on the shaft and to gravitate against the projections or
ledges 48 when not held aloof by other means.
The carriages 33-34 are reciprocated back and forth upon their rails 29-30 by
a suitable connection with the driving shaft 18 but which of course is capable of
being rendered inoperative when it is desired to operate the fly delivery mechanism.
This operative relation or connection between the shaft 18 and the carriage 33-34
is preferably established by means of a connecting rod 51 which is pivoted at one
end to the cam 17 and is detachably connected at its other end to a lever 52 keyed
to a shaft 53 extending athwart the machine in a plane below the fingers 10 and 44.
One arm of the lever 52 is duplicated as shown at 54 at the other end of the
shaft 53, and each of the levers 52-54 is connected by connecting rods 55-56
respectively to a pivot pin 57 on each of the carriages 33-34 so that as the cam 17

page_text: rotates the levers 52-54 will be thrown first into the position shown in Figures 1
and 4 and will then be projected forwardly, forcing the carriages 33-34 to the
outer extremity of their traverse or to the left hand ends of the rails 29-30, when
view as in Figure 1. The rod 51 is connected to the lever 52 by means of a
hook 58 engaging with a pin 59 on one arm of the lever 52, so that the rod 51 may
be detached and rested upon any suitable support or lug 60 when it is desired to
throw the reciprocating delivery out of operation. These parts are so proportioned
and timed with relation to the printing mechanism and the conveying tapes 9 that
the carriages 33-34 will start on their delivery movement with the sheet at about
the time the edge of the sheet reaches the stops 49 and for a short portion of their
travel they will move in unison with the tapes 9 and thus afford opportunity for the
reciprocating delivery fingers 44 gaining full possession of the sheet and preventing
the friction of the sheet upon the tapes from pulling it away from the stops 49.
Ordinarily therefore my improvel delivery is operative without other means for
gripping the edges of the sheet and holding it in firm contact with the delivery
fingers 44, but in order to guard against the possibility of the displacement of the
sheet upon the projecting ledges 48 I prefer to employ means for automatically
impinging the edge of the sheet against the delivery fingers 44 or which amounts to
the same thing, against the projections 48. This means consists preferably of a
number of grippers consisting of a number of springs 61 secured to arras 62 which
are in turn rigidly attached by hubs and set screws 63 to the rocker shaft 50.
These springs 61 are also arranged at an angle to the plane of the projections 48
so that the sheet may readily pass under them, and their lower ends are preferably
notched, as shown in Figure 5, so as to afford a firmer grip upon the sheet and to
press the latter securely against the ledges 48. Their upper ends are turned
upwardly in the form of guards 64 so as to ensure the passage of the sheet under
them.
When the carriages 33-34 return to receive the sheet from the tapes 9 the
grippers 61 rise a short distance from the ledges or projections 48 to permit
the sheet to pass under them and to come into contact with the stops 49, and at the
other end of the traverse of the carriages 33-34 the grippers 61 again ascend and
in so doing come against the inner sides of the stops 49 and also lift them clear of
the projections 48 so as to permit the sheet to slide from the latter onto the piling
table. I will now describe the mechanism for accomplishing this operation: The
shaft 50 is provided on one end with a shoe which is composed of a runner or
cam-like portion 66 on one side a projection 65 on the other, and which shoe is
securely fastened to the shaft 50 by means of a set screw 67, or other suitable
device, so that the oscillation of the shoe will also cause the shaft 50 to rock.
Secured to the top of carriage 33 is a spring or presser arm 68 which bears normally
upon an angular projection 69 formed on the upper side of the shoe 65-66. This
spring is provided with an offset or angular bend 70 from which continues a
portion 71 formed in substantially a parallel line with the main portion of the
spring 68 and which portion 71 terminates in a hook 72. The spring 68 in pressing
upon the projection 69 tends to hold the shoe in either position in which it might
be tilted. When the grippers 61 are down in engagement with the ledges 48 and
impinging the sheet the projection 69 is tilted on the left of the center and is resting
against the offset 70 and the shoe is held in this position by the pressure of the
spring 68 which is then down in engagement with the apex of the projection 69.
But by this time the carriages 33-34 reach the traverse of their delivery movement
or the extremity of their travel on the left, the under edge of the projection 65
comes in contact with a dog or pin 73 upon the side of the rail 29. As soon as the
projection 65 engages the dog 73 the reciprocating delivery starts on its return
movement and in doing so forces the end 65 of the shoe upward and consequently
instantly raises both the grippers and the stops and permits the sheet to pass or fall
onto the piling table as the fingers 44 recede or return for another sheet. In thus
raising the grippers at the instant the return movement of the delivery begins
instead of at its completion, I avoid imparting a further forward impetus to the

page_text: sheet by rising movement of the grippers whose frictional contact with the sheet
is liable to have this effect. This action of the dog 73 forces the projection 69-.
past the offset 70 and over against the hook 71. The projection 69 is held in this..
position tilted to the right of the center and the grippers and the stops consequently
held aloof from the projections 48 until the carriages 33-34 are about to complete.
their return movement whereupon the lower edge of the runner 66 comes in contact.
with a pin 74 projecting from the side of the rail 29 at or near the opposite end of
the pawl 73. This causes the shoe 65-66 to be tilted to the left, carrying the
projection 69 over into engagement with the inclined offset 70 and which inclined
offset under the pressure of the spring 68 would co uplete the oscillation of the
shre 65-66 and cause the grippers 61 as well as the stops 49 to again descend!
into contact with the projections 48, but arranged on the side of the rail 29 is a
cam or incline 75 with which engages a pin 76 projecting from the side of the
runner 65 and which cam and pin 75-76 co-operate in holding the shoe 65-66 in
the position indicated in Fig. 3 with the apex of the projection 69 resting inter-
mediate the ends of the offset 70 and when in this position the grippers 61 are
sufficiently low to permit the stops 49 to descend against the projection 48, as-
shown more clearly in Fig. 4, while the grippers themselves are slightly elevated
from such projection 48 so as to permit another sheet to pass under them and to.
come squarely against the stops 49. The cam 75 is provided at one end with an
inclined edge 77 while the remainder of its upper edge is substantially straight
and parallel with the upper edge of the rail 29 so that the grippers 61 will remain
throughout a small fraction of the travel of the carriages 33-34 and will be
permitted by the incline 77 to be gradually forced down into engagement with
the sheet under the influence of the spring 68 bearing with its inclinel offset 70
upon the projection 69. If desired the cam 75 may be rendered adjustable on the
rail 29 by the use of set screws 78 passing through slots 79 in the cam 75 and
thus securing the latter to the rail 29. The inner edge of the cam 75 is rabbeted.
as indicated in Figure 3 in dotted lines and in Figure 5 in full lines so as to permit
the lower edges of the runners 65-66 to pass without objection.
When the pin 76 passes down the incline 77 and the offset completes the tilting
movement of the shoe and thus brings the grippers 61 into firm engagement with
the sheet, the apex of the projection 69 will be in engagement with the main
portion of the spring 68 as before described and the parts will remain in this.
position until the lower edge of the projection 65 comes into engagement with the
dog 73, as before explained, and by the time this occurs, the finger 80 secured in.
any suitable manner to the shaft 42 which carries the fingers 44, comes into.
engagement with the upper end of a lever 81 pivoted in a standard 82 and having
its lower end or arm connected by a rod 83 with a crank 84 on a rocker shaft 85
which bears a number of pushers or fingers 86 which may be termed pushers.
because they in effect push the sheet from the fingers 44 as the latter recede..
When the finger 80 strikes the lever 81 it causes the pushers 86 to stand in an.
upright position between the fingers 44 and consequently as the latter recede or
return towards the cylinder the sheet is crowded off of them and falls onto the
piling table 14, the latter being provided at its lower or outer end with the usual
spring stops or gauges 87 against which the lower edge of the sheet strikes and
which serves to pile the sheets in regular order, as will be understood. By the time-
the shaft 42 of the reciprocating delivery mechanism reaches the pushers 86 the
sheet has been substantially pushed off of the reciprocating delivery and the
shaft 42 by coming into engagement with the pushers 86 forces the latter down out
of the way into the position shown in Figure 1, so that when the fingers return
with another sheet the shaft 42 passes over the pushers 86 without engaging
therewith.
The shaft 85 which carries the pushers 86 is journaled in a pair of castings or
slides 88-89, one on each side of the machine and the casting 88 is provided with
two stops 90-91 which limit the movement of the crank arm 84, the stop 90
limiting such movement when the crank is thrown by the engagement of the

page_text: shaft 42 with the pushers 86, while the stop 91 serves to limit the reverse movement
occasioned by the finger 80 striking the lever 81. The castings 88-89 are
adjustable longitudinally of the line of movement of the delivery fingers 44 so as
to have the pushers 86 in the proper position for various sizes of sheets. To this
end I journal in the castings 88-89 a transverse shaft 92, upon each end of which
is secured a pinion 93 which pinions engage respectively with two rack bars 94
secured along the upper edge of the piling table 14 on each ride, and the shaft 92
is provided with a crank 95 whereby the pinions 93 may be simultaneously rotated
and thus cause the castings or slides 88-89 to move in unison along the rack
bars 94. When the proper adjustment is reached the slides may be held against
further movement by means of a set screw 96 passing through the casting 88 and
impinging the shaft 92. This of course necessitates an adjustable connection
between the rod 83 and the crank arm 84 which may be effected by means of a
block 97 pivoted to the crank arm 84 and having a set screw which impinges the
red 83 passing through it. The foot of each of the castings 88-89 straddles the
rack bar 94 and is cut away, as clearly shown in Figure 1, to permit the pinion 93
to engage with the teeth of the rack bar. The upper edge of the table 14 is
channeled under the rack bar 94, shown at 94, and the foot piece of the casting
or slide 88-89 is provided with an inwardly projecting flange shown in dotted
lines at 88 which engages in this channel 94 and holds the casting in place.
Owing to the rapid movement of the sheet while being conveyed to the grippers 61
by the tapes 9, the sheet is liable to ride the wind or float upwardly as its forward
edge comes from the tapes and thus fail to properly enter the space between the
grippers 61 and the projections 48, and in order to guard against this I arrange
over the tapes 9 a series of guide fingers 98 whose lower ends project under the
upwardly curved ends 64 of the grippers 61. These guide fingers 98 must of
course be of such a character as to be capable of removal when the fly delivery
mechanism is to be operated, and in order that this may be accomplished with but
the minimum loss of time, I secure the ends of the fingers 98 to a transverse bar 99
(see Figure 2), by means of castings 100 having set screws 101 holding the castings
from rotation on the bar 99. The ends of the bar 99 are squared or flattened, as
shown at 102, and these euds are seated in notched brackets 103 arranged on each
side of the machine so that the bar 99 may be readily lifted out of the notched
brackets and the guide fingers 98 thus removed from the path of the fly
fingers 10.
When the reciprocating delivery is in operation the parts are in the condition
more clearly illustrated in Figure 1 with the roller 20 out of the line of movement
of the cam 17, but when it is desired to render the reciprocating delivery inactive
and to operate the fly delivery, the series of guide fingers 98 is removed by
lifting the bar 99 ont of its sockets in the brackets 103; the hook 58 is then
disengaged from the pin 59 and the rod 51 rested upon pin 60; the levers 52-54
are then forced over to the left carrying the carriages 31-34 to the extremity
of their movement in that direction and the carriage is held in this position by
means of a pin 104 which is passed through a perforated lug or ear 105 on each
of the levers 52-53 and engaging in a slot 106 in each of the rails 29-30, thus
binding each of the levers 52-54 to one of the rails 29-30. When this has
been accomplished the rails 29-30 may be stood upward in a slightly leaning
position on their pivots 31 in the manner shown in Figure 8 in which position
the rails 29-30 are held by stops or lugs 107 formed on the portions 32 of the
frame. The set screws 43 which bind the finger shaft 42 are now loosened and
the shaft 42 rotated until the fingers 44 of the reciprocating delivery assume
the position indicated in Figure 8, or are sufficiently turned out or upward to
permit the fly fingers 10 to pass between the rails 29-30 without striking the
fingers 44. The release of the lock 26 from the arm 19 then completes the
conversion of the mechanism from the reciprocating delivery to a fly delivery and
this conversion may be effected in an exceedingly short space of time.
The piling table 14 is provided at its inner end with trunnions 108 secured to the

page_text: upper side of the table by means of plates or castings 109 and these trunnions are
mounted in open bearings 110. The outer edge of the table is supported by
legs 11 on a portion 112 of the frame. The table 14 is of less width than the
distance between the rails 29-30 so that the table and the mechanism carried
thereon may be raised between the rails 29-30 in the manner shown in Figure 3
without the necessity of lifting the rails 29-30 and the mechanism carried thereby,
when it is desired to gain access to the inking rollers 113. In order that the table
may be supported in its elevated position I provide the same on each side with a
pin 114, which pins are capable of being drawn out over the rails 29-30 anl thus
supporting the table thereon. In Figure 9 which illustrates a modification of the
stops 49. instead of making the stops independent of each other, they are composed
of a single plate 49" which extends entirely across the series of delivery fingers and
is provided with cut-away portions 49 for the accommodation of the castings 63.
The object-of this is to protect the end of the sheet from the current of air, as
heretofore explained.
As shown more clearly in Figure 4 the pusher fingers 86 are preferably formed
of thin steel, or other flexible material, and wound around the shaft 85 which is
formed with a V-shaped groove 86" into which the ends of the fingers 86 are
turned. This construction avoids any possibility of damage to the fingers 86 or to
the reciprocating delivery if by accident the fingers should be turned upward while
the delivery is advancing or moving forward. Should this occur the shaft 42 of the
delivery would strike the fingers and turn them down, the part of the finger
encircling the shaft 85 turning freely thereon and forcing the end out of the
groove 86.
When thus displaced the fingers may be readily returned to their
normal position with the inturned ends engaging in the groove 86 by simply
turning them on the shaft 85 until the groove is re-engaged.
A spring 82 mounted on a stud projection from standard 82, bears against the
levers 81 and retains it in position, as will be understood from Figs. 6 and 7, and a
stop lug 81* upon the standard 82 limits the movement of the lever 81 in one
direction, as shown at Fig. 6.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
