IMPROVEMENTS IN PAPER BAG MACHINES
Year: 1878

page_text: LETTERS PATENT to Louis Francis Winter, of Hunter Street, Brunswick
Square, in the County of Middlesex, for the Invention of "IMPROVEMENTS IN
PAPER BAG MACHINES."
Sealed the 28th December 1878, and dated the 24th July 1878.
PROVISIONAL SPECIFICATION left by the said Louis Francis Winter at
the Office of the Commissioners of Patents on the 24th July 1878.
LOUIS FRANCIS WINTER, of Hunter Street, Brunswick Square, in the County
of Middlesex. "IMPROVEMENTS IN PAPER BAG MACHINES."
My Invention consists in the combining of printing apparatus with bag making
machinery, such as described in the Specification of Letters Patent granted to Lyle
Nelson, No. 4473, dated 27 Nov. 1877, so as to produce a compound machine
whereby paper fed from the roll at one end of the machine shall be delivered in the
form of printed bags at the other end of the machine.
According to my Invention the bags as they pass from between the outer creasing
rolls are guided towards and passed between an impression cylinder and a printing
cylinder suitably actuated to accord in their operation with the delivering action of
the outer creasing rolls.
In connection with. the printing cylinder I arrange suitable inking apparatus,
which is operated from a moving part (or parts) of the bag making machinery.

the said Louis Francis Winter in the Great Seal Patent Office on the 24th
January 1879.
LOUIS FRANCIS WINTER, of Hunter Street, Brunswick Square, in the County of
Middlesex. "IMPROVEMENTS IN PAPER BAG MACHINES."
This Invention consists in the combining of printing mechanism with bag making
machinery such as described in the Specification of Letters Patent granted to Lyle
Nelson, No. 4473, dated 27th November 1877, so as to produce a compound
machine whereby paper fed from the roll at one end of the machine shall be delivered
in the form of printed bags at the other end of the machine.
According to this Invention the bags as they pass from between the outer
creasing rolls travel towards and pass between an impression cylinder and a
printing cylinder suitably actuated to accord in their operation with the delivering
action of the outer creasing rolls.
In connection with the printing cylinder I arrange suitable inking apparatus 1
which is operated from a moving part (or parts) of the bag making machinery.
In the accompanying Sheet of Drawings,-
Fig. 1 is a side elevation shewing the creasing rolls and a portion of the framing
of the bag making machine with the printing mechanism attached.
Fig. 2 is a section taken in the line A, B, of Fig. 3.
Fig. 3 is an end view; and Fig. 4 is a plan.
8, S, are the outer creasing rolls, from which the bags pass to be printed between
the impression cylinder 1 and the printing cylinder 2, which are suitably actuated
from the axis of the larger creasing roll by the gearing 16, 17, 18, and 19.
3 and 4 are inking rollers; 5 is a distributing composition roller; 6 is a roller 2
which receives ink from the ink duct 11.
The pinion 4* on the axis of roller 4 is driven by the spur wheel 2* on the axis
of the printing cylinder 2.
The rollers 3 and 5 are driven by contact.
2
The roller 6 has on its axis a ratchet wheel 7, operated by a ratchet or pawl 8, 3
carried by the ratchet lever 9, which is worked backwards and forwards by a con-
necting rod 10, connected to a lever of the bag machine, which lever is marked e² in
the Drawings of Nelson's aforesaid Specification.
6* is a vibrating ink transferring roller carried by arms a fixed on an axis b,
provided with an arm c, with counterbalance weight d; e is a pin projecting from a
one of the said arms, and actuated by a tail piece f, which is a continuation beyond
the axis of the ratchet lever (shewn separately in Fig. 5).
The vibrating roller 6× takes ink from the duct roller 6, and transfers it to the
distributing roller 5, which, in turn, distributes the ink on the rollers 3 and 4,
whereby the type or printing surface of the printing cylinder is properly inked.
The frames 12 are shewn connected to the end of the main framing of the bag
machine by bolts 13, but may be made in one therewith; 14 are guides for the bags
as they pass from between the printing and impression cylinders; 15 is a spring
to allow play between the printing and impression cylinders; 16 and 17 are two
spur wheels for driving the printing and impression cylinders, they are driven by
the small wheel 18, which itself is driven by the wheel 19 on the axis of the roller
S of the bag machine.
The axis of the roller 6 is supported by the frames 12, being centred at one end on
the bolt 20 for convenience of removal. On this axis are pivotted the arms or sup-
ports 21, carrying the rollers 3, 4, 5; these arms rest at their outer ends on
springs 22, so as to press the rollers 3 and 4 up against the type or printing surface
without undue shocks. The springs 22 are supported on moveable pieces 23,
which are kept in a fixed position by levers 24, pivotted to the cross piece 25,
carried by the frames 12.

page_text: At the inner end of each lever 24 is a notch, into which a projection 26, at the
bottom of the corresponding piece 23, takes so as to hold the pieces up in the fixed
position.
Springs 27 (Fig. 4) serve to keep the notches up against the projections.
If the inking rollers are required to be lowered the levers 24 are turned round
horizontally underneath the cross piece 25, thus allowing the pieces 23 carried by
the supports 21 to fall by the latter turning on their shaft.
.
28 are adjustable bearings for the axes of the rollers 3, 4, and 5; these bearings are
fixed in the required positions on the supports 21 by bolts passing through slots as
shewn.
The printing surface of the printing cylinder may be formed of type or stereo, or
like an india-rubber stamp, but curved to the proper radius.
I desire it to be understood that I do not confine myself to placing the inking
apparatus in the exact position shewn, as it may be in some cases convenient to
arrange it otherwise, as, for instance, in front of the printing cylinder instead of
behind, as shewn.
It will be evident also that the number of inking rollers and other details may
be varied without departure from the distinctive character of the Invention.
What I claim is, the combining the bag making and printing mechanism so
as to form a compound machine, substantially as herein-before described with
reference to the Drawings.
In witness whereof, I, the said Louis Francis Winter, have hereunto set my
hand and seal, this Sixth day of January, in the year of our Lord One
thousand eight hundred and seventy-nine.
LOUIS F. WINTER. (L.S.)
