PRINT FEEDING MECHANISM FOR WRAP
PING AND PACKAGING‘MACHINES
Edward F. Ness, Toledo, Ohio, assignor to Morris
Packaging Equipment Company, Toledo, Ohio,
a corporation of Ohio
Original application July 16, 1935, Serial No.
31,630. Divided (and this application June 25,
1937, Serial No. 150,348
Claims; (Cl. 198—34)
This invention relates to article wrapping and
packaging machines but more particularly to ma
r
chines for wrapping individual bars of butter,
oleomargarine and the like with relatively thin
?exible sheet material such as parchment paper,
and packaging one or more wrapped bars into
cartons.
This application constitutes a division of Pat
ent 2,111,901, issued March 22, 1938, and entitled
“Wrapping and packaging machine,” and is con
cerned particularly with the feeding of prints or
bars to the wrapping mechanism.
An object is to produce a new and improved
mechanism for advancing bars to the wrapping
15 mechanism in such manner that they are prop
erly spaced from each other so that they may be
introduced into the wrapping mechanism in prop‘
erly timed relation and so that‘ inspection thereof
can be conveniently made, an opportunity being
20 afforded to remove damaged bars or prints and
replace them with others without interrupting
the movement of the several bars.
Other objects and advantages of the invention
reside in details of construction, arrangement and
25 operation hereinafter described, and, for purposes
of illustration, an embodiment of the invention
is shown on the accompanying drawing, in which
Figure 1 is a vertical sectional elevation of a
portion of a wrapping and packaging machine
30 showing somewhat diagrammatically the primary
bar or print feeder and the conveyor for advanc
ing the individual prints to a vertically moving
ram which is operable to advance the individual
bars to the wrapping mechanism;
Fig. 2 is a top plan view of the mechanism
35
shown in Figure 1; and
Fig. 3 is a detail view showing the driving
mechanism for the chain conveyor.
Referring to the drawing, eifort has been made
40 to omit unnecessary disclosure of the parts which
tend only to obscure the real invention, but, on
the contrary, as many parts have been shown
diagrammatically to facilitate understanding of
the structure and operation of the mechanism
45 so that the nature and operation of the inven
tion will be readily understood by those skilled
in this art.
As shown, the primary feeder A to which the
individual bars ID of butter, oleomargarine or
the like, in this instance of one-quarter pound
size, are delivered, comprises a movable table H
which reciprocates between stationary guides
Ila, on which opposite ends of the prints I0 rest.
Motion is imparted to the table II by a rocker
55 arm l2 having a roller l3 at its upper end oper
ating in a vertically disposed guide [4 ?xed to
the table, this mechanism operating to recipro
cate the table ll longitudinally. At predeter
mined points in the. swinging movement of the
arm [2, the table is raised and lowered; raised
during the advancing movement of the prints
and lowered during the retracting or retrograde
movement of the table. This latter is accom
plished by an arm l5, which is pivotally con
nected at its lower end to a horizontal arm IS, 10
the latter being ?xed to a swinging arm ll. 7
The upper end of the arm 15 has a cam sur
face l8 to engage the table II and carries a
roller l9 which is adapted to move in a vertically
disposed guide 20 on the table. Connected to the
lower end of the rocker arm I2 is a rod 2| and
connected to the lower end of the arm I‘! is a rod
22, the opposite ends of these rods being driven
in any suitable manner to effect the desired
20
movement.
It should be noted that the arm I1 is ?xed to
a shaft 23 with which a vertical arm 24 is rigid.
A link>25 for operating an arm similar to the
arm 15 adjacent the forward end of the table
extends from the arm 24. A link (not shown) 25
extends from the upper portion of the arm l5
and cooperates with the link 25 for e?ecting the
desired motion.
v
n The bars or prints l0 are thus advanced step
by step toward a pusher 21 passing beneath a 30
guide 28 disposed above a stationary platform 29.
The prints III are pushed upon the platform 29,
the foremost print being moved beyond the for
ward edge of the platform, whereupon the pusher
21 engages its upper surface and pushes it down 35
wardly to the chain conveyor B. A bell crank 30
is driven in any suitable manner by a rod 3|
and engages the lower end of the pusher 21 to
impart. the vertical reciprocatory movement
40
thereto.
The chain conveyor comprises a pair of chains
32 spaced laterally from each other and mounted
on the chains is a series of shelves or platforms
33, each being secured at its forward end to a
stop member 34; The shelves 33 are arranged in 45
pairs, one being secured to each of the chains,
and adjacent the opposite end of each shelf 33
is another stop member 35. The pusher 21 lowers
the individual prints l0 so that opposite end por
tions thereof rest upon the platforms 33. The 50
lugs 34 and 35 a?ord a safety measure so that
when it becomes necessary for the operator to
replace a bad or damaged print or bar, he can
place it on the chain conveyor in the proper po
sition. It will further be apparent that the chain 55
2
2,152,970
conveyor is such that the prints delivered there
to can be readily and conveniently inspected,
thereby to insure that only good prints will be
delivered to the wrapping mechanism. The
prints must be placed properly upon the chain
conveyor since the ram which raises them, as
will hereinafter appear, operates in timed rela
tion to the chain and if the prints are not prop
erly disposed on the conveyor, they will either
not be engaged by the rim or will not be prop
erly engaged to advance them in the desired
manner.
The chain conveyors are trained over sprock
ets disposed at opposite ends thereof in the usual
15 manner, and a shaft 36 on which the forward
sprocket is mounted, has a small gear 31' mesh
ing with a larger gear 38 to which is ?xed a
smaller sprocket 39 to receive a chain drive 4|]
driven in any suitable manner so that the chain
20 conveyor B advances the articles three times as
fast as the primary feeder A. Thus, by spacing
the prints in the manner effected by the chain
‘conveyor, each print may be inspected by an
operator and if one print is injured or damaged
25 or is otherwise unsuitable for wrapping, it can
be replaced by another one.
The prints III are individually lifted from the
chain conveyor B by a vertically movable ram 4|
which moves upwardly between the chains 32
30 and engages the undersurface of a print, forc
ing the same upwardly into the Wrapping mech
anism C. Vertical movement is imparted to the
35
given merely by way of illustration, and it is
to be understood that changes in details of con
struction, arrangement and operation may be
effected without departing from the spirit of the 5
invention especially as de?ned in the appended
claims.

.What I claim is:
1. In an article Wrapping and packaging ma
chine, means for advancing a series of prints
of butter or the like to form a row with the prints
substantially in engagement with each other,
a platform to, receive the foremost print from
which same is, pushed by oncoming prints, a
pusher to engage the foremost print as same is
moved from said platform and move same at
substantially right angles to said advancing
means, an endless conveyor to receive at one end
thereof prints from said pusher, said conveyor
comprising a pair of laterally spaced endless‘ 20
chains, relatively movable shelves on said chains
respectively for receiving opposite ends of indi
vidual prints, and a ram at the opposite end
of said conveyor to engage the underside of a
print and discharge same vertically therefrom. 25
2. In an article wrapping and packaging ma
chine, means for advancing a series of prints of
butter or the like to form a row with the prints
substantially in engagement with each other, a
platform to receive the foremost print from 30
‘which same is pushed by oncoming prints, a
ram 4| by a rocker arm 42, connected by a link
pusher to engage the foremost print as same is
moved from said platform and move same at
43 to the lower end of the ram, the latter being
guided in its vertical movement by a guide 4| a.
Any suitable means may be provided for impart
means, an endless conveyor to receive at one end ‘
ing vertical oscillatory movements to the arm
42 in timed relation to the movement of the
chain conveyor B.
Detailed description of the wrapping mecha
nism C is not considered necessary. Suffice it
to say that the individual prints or bars l0 en
gage relatively thin ?exible sheet material such
as parchment paper which’ is delivered into the
45
to be understood that the above description is
substantially right angles to said advancing
thereof prints from said pusher, said conveyor
comprising a pair of laterally spaced endless
chains, relatively movable shelves on said chains
respectively for receiving opposite ends of indi
vidual prints, a spacer indicator on opposite sides 40
of each shelf for predetermining the proper
positioning of each print, means to impart con
tinuous movement to said conveyor so that the
path of movement of the print and the print and
sheet material are advanced through folders for
prints are advanced thereby faster than by said
advancing means, and a ram at the opposite end 45
effecting the desired folding operations.
print and discharge same vertically therefrom.

Although the above described mechanism is the
best form known to me at the present time, it is
of said conveyor to engage the underside of a
