Improvements in Delivery Apparatus for Printing Presses.
I, SAMUEL GEORGE Goss, of 335 to 351, Rebecca Street, Chicago, Cook County,
Illinois, United States of America, Manufacturer, 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 to delivery apparatus for printing presses, and has for its
object to provide various improvements by which papers of various sizes may be
delivered expeditiously. To this end my invention consists in the various com-
binations and arrangements hereinafter described and pointed out in the claims.
In the drawings,
Figure 1 is a side elevation;
Figures 2 to 6 inclusive are diagrammatic views showing the position of the
sheets at different stages of the operation;
Figure 7 is a side elevation of one of the cross-heads;
Figure 8 is a side view of the arm by which the folding blades are silenced;
and
Figure 9 is a vertical section on line 9-9 of Figure 6, showing the manner
of locking said arm in position.
Referring to the drawings,
A
10 indicates the frame of the press. 11 indicates a former, which is used to
longitudinally fold the web before it is conducted to the delivery press. Rollers 12
are preferably arranged at the apex of said former to draw the web over it and
to lay the fold, but other well known mechanism may be used if desired.
slitter is also provided for slitting the web longitudinally. I wish it to be under-
stood, however, that my invention is not limited to the use of my improved cut-
ting, associating and folding mechanism for the treatment of a longitudinally-
folded web, since, if desired, a web of single width may be used, in which case
single sheets may be delivered from the press having a single transverse fold;
or by arranging the delivery apparatus for associating, two associated sheets may
be delivered with a single fold. When the longitudinal folding mechanism is
employed the number of sheets delivered is doubled. (It will be understood that
the word "sheet" as hereinafter used is intended to include either a portion
severed from a web of single thickness, or from a web of double thickness,-that
is, a web folded longitudinally; the action of the associating mechanism being
the same in either case.)
14 indicates the web: 15, a roller around which the web is conducted; 16-17,
cutting cylinders, one of the cylinders, as 17, provided with a blade 18 adapted
to enter a recess 19 in the cylinder 16, as shown in Figure 1.
20 indicates a folding cylinder mounted upon a shaft 21, in which cylinder
are mounted shafts 22-23, which carry folding or tucking blades 24-25 respec-
tively, as shown in Figure 2.
Upon one end of each shaft 22-23 is mounted a cross-head 26, carrying
rollers 27-28, as shown in Figure 1. The rollers 27-28 are adapted to be

page_text: engaged by a cam 29 mounted upon a shaft 30 arranged in the frame of the press
opposite the meeting edges of folding rollers 31-32. The arrangement of the
cam 29 and cross-heads 26 is such that as the cross-heads are moved around by
the rotation of the cylinder 20 the rollers 27-28 will come in contact with the
cam 29, thereby causing the cross-heads to turn to a radial position with refer-
ence to the rolls, thereby causing the folding blade carried by such shaft to
assume a similar position and projecting the sheet upon the cylinder into the
bite of the folding rollers 31-32. Inasmuch as the operation of such cam and
cross-heads is well understood, it will be unnecessary for me to describe it more
particularly herein.
The cylinder 20 is caused to rotate by means of a gear 33, which meshes with
a gear 34 mounted upon the shaft 21, which gear is indicated by dotted lines
in Figure 1. The gear 33 is driven from a gear 35 by an intermediate gear 36,
in any suitable'
'manner; the gear 35 is itself driven by any suitable mechanism.
Said gear 35 also drives the roller 15 through an intermediate gear 37. The
folding rollers 31-32 are driven by means of a gear 38 mounted upon a suitable
shaft 39 and driven from the gear 34. The cam 29 is driven from the shaft 21 by
a gear 40, which is mounted upon said shaft and meshes with an intermediate.
gear 41, as shown in Figure 1.
"
42-43-44 indicate upper tape rollers, carrying tapes 45, as shown in Figure 1,
The rollers 43-44 are fixedly mounted in any suitable manner; but the rollers 42
are mounted upon a shaft 46 carried by rods 47 movable in bearings 48 in the
upper portion of the press frame, by which arrangement the tension of the
tapes 45 may be adjusted as desired. A suitable set-screw 49 or other device is
provided for locking the rods 47 in position. The rollers 42-43 are arranged
over the cylinder 20 in such position that the tapes will extend over such cylinder
for a short distance to adapt them to receive sheets from said cylinder.
The
50 indicates a series of tape rollers mounted upon a shaft 51, which rollers are
arranged opposite the rollers 44, the shaft 51 being fitted in blocks 52 movable
in boxes 53 at opposite sides of the press frame, so that the position of the
rollers 50 may be adjusted, adjusting screws 54 being provided, as shown in
Figure 1. Suitable tapes 61 pass around the rollers 50 and the cylinders 20, so
that the upper portions of such tapes strip the sheets from the cylinder and
co-act with the tapes 45 to conduct the sheets away from said cylinder.
lower portions of the tapes 61, carried by the cylinder 20 and rollers 50, co-act
with a lower series of tapes 55 mounted upon rollers 56-57 and the folding
roller 32, as shown in Figures 1 and 2; the tapes 55 being so arranged as to
receive the sheets from the cutting cylinders and conduct them around to the
cylinder 20, as shown in the drawings. The rollers 57 are mounted upon a
shaft 58 carried by arms 59 which project from a shaft 60. The arrangement is
such that by rocking the shaft 60 the position of the rollers 57 may be adjusted
as desired.
62 indicates a series of grippers, which are mounted upon a shaft 63, which
shaft is journaled in the cylinder 20 and carries at one end an arm 64, upon
which is mounted a roller 65, as shown in Figure 1. The roller 65 runs over the
surface of a stationary cam. 66, the shape of which is such as to cause the
grippers 62 to be turned down toward the surface of the cylinder 20 and thereby.
grip the leading edge of the sheets upon said cylinder; thereby carrying said
sheet or sheets around the upper side of said cylinder, where they are caused to
be released by the action of the cam upon the roller 65, as shown in Figure 1.
To turn the grippers out from the cylinder 20, a spring 76 is provided, which is
mounted upon a rod 67, one end of said rod being fixedly connected to the cylin-
der 20, the other end of said rod being connected to an arm 68 carried by the
shaft 63, as shown in Figure 1. Diametrically opposite the grippers 62 is another
series of grippers 69 mounted upon a shaft 70, which shaft has arms 71-72
similar to the arms 64-68 respectively. The arm 71 carries a roll 73, and the

page_text: arm 72 is connected to a rod 74, upon which is mounted a spring 75 similar in
action to the spring 76.
The operation of the apparatus is as follows: When both the folding blades are
active, the web 14 passes between the cutting cylinders 16-17, and is there
severed into sheets. The leading end of each sheet is then impaled by pins 77
carried by the cylinder 16, and carried around to the tapes 55, when it is
stripped off the pins 77 by a shoe 78. It is then carried forward between the
tapes 55 and shoe 78 to the tapes 61. It is then carried between the tapes 55
and 61 to the under side of the cylinder 20, at which point it is seized by the
grippers 62 and its leading end carried around to the upper side of said cylinder.
When the middle portion of such sheet comes opposite the folding rollers 31—32,
it is acted upon by one of the folding blades, which doubles the sheet at the
middle line, advancing the doubled edge into the bite of the folding rollers 31--32,
by which the sheet is folded and conducted to other folding mechanism.
In case it is desired to associate two sheets before folding, one of the folding
blades is silenced. The result is that when one of the sheets arrives opposite the
folding rollers, since the folding blade does not act upon it, it is carried around
to the tapes 45, where it is received by the tapes 61 which strip it from the fold-
ing cylinder, and together with the tapes 45 conduct it around the roller 50,
where it meets the third succeeding sheet. The guide 78 serves to properly deflect
the returning sheets, as shown in the drawings. The associated sheets are then
At
carried along together between the tapes 55-61, back to the cylinder 20.
this time the two sheets will be acted upon by the active folding blade and folded
together transversely. In this way the operation is continued, every other sheet
being carried back to meet a succeeding, sheet. When it is desired to adjust the
length of the pathway formed by the tapes (1, this may be accomplished by turn-
ing the adjusting screws 54, and thereby adjusting the position of the rollers 50.
When slight adjustment is desired, the elasticity of the tapes will permit them
to adjust themselves to the altered position of the rollers 50, but where the
rollers 50 are moved a considerable distance new tapes are necessary.
The cross-heads 26 are made removable, being mounted upon feathers upon the
shafts 22-23. They are secured in place by set-screws 79, as shown in Figure 7.
For the purpose of silencing one of the folding blades, the cross-head 26 of such
blade is removed and an arm 80 is secured upon the shaft which carries the fold-
ing blade, in place of such cross-head; such arm being provided with a recess.
to receive the feather, as shown in Figure 8. The arm 80 is fixedly secured to
the cylinder 20 by means of a bolt 81 which passes through said arm and is
screwed into or otherwise secured to said cylinder, as shown in Figure 9. The
position of the arm 80 is such as to hold the folding blade in a position tangen-
tial to the cylinder 20, as shown in Figures 1 to 6. In this way one of the fold-
ing blades may be so arranged that it will not be operated by the cam 29, and
therefore every other sheet will pass around the cylinder 20 without being folded,
as is necessary when the sheets are to be associated.

invention and in what manner the same is to be performed, I declare that what
I claim is:-
