13 Claims.
This invention relates to a packaging machine
and particularly to a bottom sealing machine
of the type provided with forming blocks upon
which the cartons are supported while the bot
5 tom sealing operations are being performed.
One object of the invention is to provide a
novel and‘ improved bottom sealing machine, of
the character specified; in which provision is
made for punching holes in one of the carton
10 ?aps while the carton is supported upon the
’ forming block.
'
Another ‘object of the invention is to provide
a novel and improved bottom sealing machine of
the character speci?ed in which a punch is pro
vided at one station of operation, which is adapt
ed to cooperate with a die carried by each of
a plurality of forming blocks, successively ad
vanced into operative relationship with the
punch, and, at a succeeding station of operation,
20 a clearing pin is provided to remove the punch
‘ ings from the die.
With these general objects in view, and such
others as may hereinafter appear, the invention
consists in the bottom sealing machine, in the
mechanism for perforating the carton ?ap, and
in the various structures, arrangements and
combinations of parts hereinafter described and
particularly de?ned in the claims at the end of
this speci?cation.

Referring now to the drawings, the different
features of the invention are illustrated as em
bodied in a machine for bottom sealing cartons,
and except as to such details as are hereinafter
pointed out, the illustrated‘machine comprisesl
any of the usual forms of bottom sealing ma
chines now upon the market, Reference is made
to the United States patent to Scales, No.
‘767,445, dated August 16, 1904, as disclosing the
details of construction and mode of operation of 10
such prior art bottom sealing machines'
As is generally known, and as illustrated in
the Scales patent above referred to, these prior
art bottom sealing machines have included a
plurality of forming blocks upon each of which 15
a carton is placed by suitable mechanisms, with
the bottom ?aps of the carton projecting below
the bottom of the block.
Successive cartons are
placed upon successive blocks, as each block
is moved into a de?nite station, and thereafter
a particular block with its carton is intermit
tently revolved through successive steps of 90
degrees to permit the different operations of
folding and sealing the bottom ?aps of the
carton to be performed.
25
Inasmuch as many portions of the bottom seal
ing machine of themselves constitute no part
of the present invention, it has been deemed
sufficient to illustrate only sufficient portions of
the bottom sealing machinev as will enable the
present invention to be understood, and as here
in shown, til represents the usual rotatable spider
upon which four forming blocks 12 are mount
ed to revolve therewith. The different stations
of the machine, as diagrammatically illustrated
in Fig. 1, include: station l, at which the carton
is placed upon a block; station 2, at which the
bottom ?aps‘are folded and sealed; station 3,
‘ 5, 6 and 7 are details of the punch and die to
at which pressurev is applied to the bottom of
40 be referred to, Fig. '7 being a cross section on
the'carton to ?rmly set the sealed flaps; and,
station ii, at which the carton is removed from
the line 1-1 of Fig. 6; and Fig, 8 is a side ele
vation of the mechanism for clearing the
punched out portion of the carton ?ap from the
block.
The preferred embodiment of the present in
vention contemplates a bottom sealing machine
.of1 the type provided with forming blocks on
:which the ‘cartons are supported while the bot
tom sealing operations are performed and in
I50 which provision is made for‘ punching out or
perforating one of the top ?aps of the carton
thus supported on, the block and for remov
ing the punched out sections remaining in the
forming block at a succeeding station and after
the carton has been removed from the block.

the block and delivered to an outgoing conveyor
8 to be carried away from the machine.
The spider ii! is arranged to be intermittently
rotated by the usual form of‘ Geneva drive in
cluding the Geneva wheel M and driver it
through the cooperating gears l8, 2!}. The
driver it is rotated from a convenient source of
power through a shaft 22 and bevel gears 24,
25, the latter being mounted upon a drive
shaft 28.
Referring now to Figs. 1 and a, the mecha
nism, forpunching holes in the carton flap,
generally indicated at' 32, is located at station 3,
where the operation of applying pressure to the 55

bottom of the block, to set the previously sealed by a spring I24 connected to the lever I04 and to
bottom ?aps of the carton, is performed. As a pin I20 secured in the slide bracket 94. The
herein shown, the punching mechanism com
prises a punching member 40 provided with a
rear face of the slide member 92 engages a stop
member I28, made of leather or other sound
plurality of punches arranged to be recipro
absorbing material, when the slide member is in
catedrtoward and from the block in a slide
its retracted position. In operation, the stripping
?ngers H0 engage the upper ends of the side
bracket 42 secured to the machine frame. The
die 44 is secured to and forms a part of the
flaps of the carton and strip the carton from the
forming block. During its descent, the bar I06
engages the lever I04 which operates to project . .4 0
of
die
openings
as
shown.

As herein illustrated, the bar I06 engages the
ranged to enter holes 48 in the die 44 prior to the
lever I04, near the end of the stroke of the strip 15
15 engagement of the punches 50 with the carton
block l2 itself, and is provided with a plurality
flap and the die. Inasmuch as the block, upon
which the die is mounted, may not come to rest
in perfect alignment with the punching mecha
nism, the die 44 is arranged to be movable with
20 respect to its block I2 so that when the registering
pins 46 enter the holes 48 the die may be moved
thereby into alignment irrespective of slight ir
regularities in the position of the block. As
herein illustrated, see Figs. 6 and 7, the die plate
I25 44 is movably secured to the block by shoulder
screws 52 and under the head of each screw a
spring washer 54 is inserted. Clearance holes are
provided in the die around the head and shoulder
of each screw so that while the spring washer
(£30 operates to hold the die plate to its block, the die
plate is permitted to be shifted slightly with rela
tion to the block. It will also be noted that clear
ance is provided in the block around the die plate
as at 56 and 58 to permit shifting of the die.
In the illustrated machine, provision is made

actuated, thus exposing the openings in the die.
From the description thus far and by reference
to Fig. 3, it will be observed that the improved 20
carton produced by the present machine may be
used so that when ?lled and sealed, the punched
openings in the carton ?ap serve as pouring
openings. After the carton has been ?lled the
narrower side ?aps may be ?rst turned down and £5
then the wider side ?ap with the punched holes
therein may be folded upon the previously folded
down narrower flaps and adhesively secured
thereto. The ?nal flap is then folded down to
cover the punched openings in the previously 30
folded side flap and to complete the sealing of
the carton. When the carton is used, the ?nal
flap may be raised to expose the holes in any
convenient mannenfor example, by inserting a
for operating the punching member 40 from the
existing mechanism for pressing the bottom of
the carton against the block. As herein shown,

the machine frame, and a connecting rod 82
joined to a connecting member 84 secured to the
outer end of the presser member 60.
Provision is made at the next'station of opera
tion for clearing the die 44 of the punched out
portions of the carton ?ap left in the block as a
result of the punching operation and, as herein
shown, see Fig. 8, the clearing pins 90, secured
in a slide member 92, are operatively connected
to the present mechanism for stripping the com
pleted carton from its block. The slide member
60 92 is arranged to slide in a bracket 94 secured
to the machine frame and the slide member is
connected to a rock lever 96 by a link 98. The
rock lever is secured to a rock shaft I00 suitably
mounted in a bracket I02 secured to the machine
165 frame. A second lever I04, fast on the rock‘ shaft
I00, extends into the path of a bar I06 secured
to the stripping bracket I08. The stripping
bracket, which carries the strip-ping ?ngers H0
is slidably arranged on a vertical slide H2, see
Fig. 2, and is vertically reciprocated at each cycle
of operation of the machine, through connections
including a connecting rod H4, lever H8, H8,
in the flap.
