Improvements in Delivery Mechanism for Printing Machines.
I, HENRY EDWARD NEWTON, of the Office for Patents, 6, Breams Buildings,
Chancery Lane, in the County of London, Patent Agent, 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:
-
The present invention has for its object to provide a convenient means for
cutting sheets from a web and collecting the same, capable particularly of appli-
cation to delivering products having small sized sheets; and it consists in
certain constructions and certain parts, improvements and combinations which
will be hereinafter described and fully pointed out in the claims hereunto
appended.
The invention further includes certain details of construction hereinafter
fully described and pointed out in the claims.
In the drawings annexed:
Figs. 1 and 2 are sectional elevations showing different positions of the parts;
and
Fig. 3 is a plan view of a delivery embodying the invention.
The web passes from any suitable printing mechanism between the two
carriers A and B. The carrier A is provided with a plurality of segmental
surfaces each corresponding in length to the sheets to be received upon it. In
the drawings three segments are shown. The number however may be varied
as desired. The carrier is preferably provided with a number of cutting
blocks 1 corresponding to the number of segmental surfaces above mentioned
with which cutting blocks co-operate knives carried by the carrier B.
The carrier A is also preferably provided with a set of pins for each of the
segmental surfaces. These pins may be mounted upon the usual spring actu-
ated shafts and are preferably provided with levers and bowls which may be
operated to withdraw the pins by the cam 2 attached to the pivoted three-
armed lever 3 by bolts 4 passing through slots in the cam, as shown in Figs. 1
and 2. The lever 3 is pivoted and is pushed in one direction by the spring 5
and is moved in the other direction by the cam 6 on shaft 7, through cam link 8.
The cam 2 is placed in the position shown in Fig. 2 when the collected sheets
on the carrier A are to be folded off from the said carrier and when therefore the
pins are withdrawn from the ends of the sheets at the position of withdrawal,
shown in Fig. 2. The cam 2 is placed with the bolts 4 at the other end of the
slots therein as shown in Fig. 1 when the sheets are to be delivered from the
collecting carrier without folding as illustrated in Fig. 1.
The carrier A may however be used for collecting sheets. In such cases
therefore it is necessary to to provide means for causing the withdrawal of the
pins to be intermitted while the given number of sheets is being accumulated
and to this end the cam 2 is mounted on the lever 3 as above described. The
shaft 7 is rotated from the cylinder B by gearing at such a relative speed that
the cam 6 will operate the lever 3 once in as many revolutions or parts of revo-

page_text: lutions of the carrier A as the latter is designed to make between successive
deliveries. When the cam 6 is not operative upon the lever 3 that lever will
by the pressure of spring 5 be in the position in which it is withdrawn so as
to be out of the path of the bowls controlling the pins and therefore the pins
as they pass the cam 2 will not be withdawn. When, however, the cam 6 is
operative it throws the cam 2 into operative position, so that as the pins pass it,
they will be withdrawn as shown in Figs. 1 and 2. Thus if two sheets are to
be collected upon each of the segments on the carrier A shaft 7 will be so
geared as to rotate once during each two-thirds revolution of the carrier A; if
four sheets are to be collected upon carrier A the shaft will be geared to rotate
once for each one and one-third revolution of the carrier A and so on.
The mechanism for folding the collected sheets off from the carrier preferably
consists of reciprocating folding or tucking blades 9 rigidly mounted upon the
shafts 10 carried by the arms 11 mounted upon shafts 12 provided with levers 13
and bowls 14 which ride upon a cam 15. While the parts are in the position
shown in Fig. 2 the tucking blades 9 will be protruded each time the bowls 14
drop into the depression of the cam 15 as shown in Fig. 2; that is once for
each one-third revolution of the carrier A.
The carrier A may however be used to collect sheets. In such cases therefore
it is necessary to provide means for causing the tucking blades 9 to intermit
their operation while the given number of sheets is being accumulated and for
that purpose the pivoted triangular lever 16 is preferably provided, pressed in
one direction by spring 17 and operated in the other direction by cam 18 on
shaft 7 through cam link 19. This lever is pushed forward while the sheets are
being collected by the cam 18 so as to force its end 20 forward into position
so as to bridge the depression in the cam 15 and prevent the tucking blade from
being protruded, but when the collection on any segment is completed the
lever 18 is moved inwards uncovering the depression in cam 15 which allows
the bowl 14 to drop therein and the tucking blade to operate. The operation
of these parts is substantially the same as that of the corresponding devices
connected with the pins and the cam 18 is mounted upon the same shaft as the
cam which governs the pins. Thus the tucking blade will be brought into
operation at the same moment at which the pins are withdrawn.
Plungers 21 may be provided for pushing out the ends of the sheets when
the pins are withdrawn in order to facilitate and make certain the transfer of
the sheets from the carrier cylinder to the delivery cylinder D. These pins are
preferably carried by arms 22 on spring shafts 23 provided with lugs 24 which
engage with lugs 25 on the pin shafts. The arrangement of the parts is such
that normally the shaft 23 is held by its spring with its lug 24 in contact with
the lug 25 and the plungers 22 are then in their withdrawn position. When
the pins are withdrawn the swinging of the lugs 25 permits the shafts 23 to
swing thus causing the plungers 22 to move outward and push the ends of the
sheets from the carrier A. as shown in Fig. 1. onto the carrier D, and causing
them at the same time to be impaled by the pins of the carrier D. This action
also takes place when the sheets are folded, as shown in Fig. 2, but is of no
special importance in this instance.
When the sheets are delivered from the carrier A unfolded, they are caught
by the pins on the carrier D and delivered to tapes 26. 27, being stripped from
the cylinder by stripper 28. When the sheets are delivered folded from the
carrier A the tucking blades 9 are brought into service and with them co-
operate pivoted jaws 29. mounted upon spring pressed shaft 30, whose bowl is
controlled by a cam 31. The cam 31 is so shaped as to cause the jaw 29 to
close on the fold of the paper and carry it around the carrier D and deliver it
to the grippers 32. In this use of the mechanism the switch 28 is thrown into
the position shown in Fig. 2. When the sheets are delivered unfolded the
iaw 29 is locked out of operation in the usual manner. So, too, in such case,
the tucking blades 9 of carrier A are also locked out of operation,

page_text: The advantages of the construction above described are based among other
things upon the following considerations.
First it is desirable to provide a carrier with a plurality of collecting sur-
faces in such machines for the reason that the sheets especially in pamphlet
and magazine work, are frequently so small that if the collecting cylinder was
adapted to receive but a single sheet it would be of an impractically small
diameter.
Second this invention involves the advantage of enabling the cutting of the
sheets to be performed while the sheets are resting upon the collecting carrier.
Thus a more perfect register of the sheets is secured than if they were cut loosely
and brought, after they were cut, to the collecting carrier; and, moreover a
smaller number of pins is required than would be the case were the sheets cut
on a separate cylinder, as the carrier B.
It will be observed that any number of sheets desired may be superimposed
upon each other upon the collecting surfaces of carrier A provided that such
number be not the same as, nor a multiple of, the number of collecting surfaces
in which case identical sheets would be superimposed.
