The present invention relates to apparatus for
applying a thin coating of sealing material, such
as paraflln or the like to containers, particularly
containers made of paper or other fibrous ma'
terial, and has for its principal object to provide
an apparatus o'f the indicated type which will be
the internal grooves provided adjacent the open ^
ends of the containers. The upper end portion of
the containers may then be >rolled in any suitable
manner so as to form a bead on the upper edges
capable -of automatically and quickly applying an >thereof which renders that portion of the con

'
from the- following description of the apparatus
as designed and used for the just stated purpose,
a triple layer of material is formed at the bottom - although evidently it may be used in the sealing
edges of the containers. The indicated type of `of other types of containers or where a coating of
container is usually closed by a disc cover which , .parafñn or other material is to be applied to the
containers for purposes other than sealing the
40 snugly ñts into an internal groove provided ad
jacent the upper edge of the container. The con
tainers may be treated with paraiiin or .other
suitable material capable of sealing the pores of
the paper material oi' which the containers are
constituted and rendering them impervious to'
i?luids. The frusta-conically shaped container
having a smaller diameter at the base portion
thereof than -at the mouth or top portion and
adapted to contain approximately one pound of
food material represents the typical shape- and
size of the containers. The filling the containers
isusually done in a iilling apparatus which dis
charges in to thecontainers the proper amount of
the commodity to be contained therein. When
55 the containers' are ñlled, the disc covers are tl‘en
covers to the containers.

Referring more particularly to Fig. 1 of the
drawings, the apparatus illustrated comprises a
v10
base or pedestal I0 having a raised hub section I I
which supports a hollow standard I2 in vertical
or upright position. Arranged adjacently to the
upper end of the .standard I2 is a circularly
shaped table I3 provided with a centrally disposed
15 hub section vI4 through which the upper end por
tion of the standard extends. Integrally formed
(not shown). Fixedly secured to the drive shaft Ul
32 of the motor is a pulley wheel 33 which en
gages with one end of a belt or drive 34, the~ other
end of such belt passing around a pulley wheel
35 iixedly secured to one end of a shaft 36. A's
shown more clearly in Fig. 2, the shaft 36 is
mounted for rotative movement in the bearing
10
brackets 31 and 38 which depend from the un
der side of the platform 21-and are afiixed there
to `by the bolts 39 and nuts 4I).4 Mounted on the shaft 36, intermediate the bearings A31 a-nd 38 15

a vertically disposed shaft or stem I9 so that the eter slightly greater‘than the diameter of the
30 gages with the inner surface of the upper end
sleeve functions to securely support said shaft
40 vertically in the upper end of the standard l2.
The table I3, the sleeve I1 and the shaft I9 are
iixedly secured in position on the upper end of
the standard I2 by means of the set screws or
bolts 20 which are in threaded engagement with
45 the hub section I4 of the table I3' and extend
through said section and through openings in the
annular walls of the standard I2 and the sleeve
I1 and engage with the outer surface of the
shaft I9.
Seated on the flange -I8 of the sleeve I1 and
encircling the shaft I9 is ,a thrust bearing 2|
50
which supports on its upper race a vertically
disposed sleeve 22 which is mounted for rotative
movement` on the shaft I9 intermediate of the
55 latter’s length. The upper end portion 23 of the
sleeve 22 which is of smaller diameter than the
~
65
70
75
remainder of the sleeve, is adapted to receive a
worm gear 24 having a centrally positioned hub
section 25 through which the reduced portion
23`of the sleeve and the upper end portion of the
shaft I9 extend. 'I'he worm gear 24 is arranged
for rotationwith the sleeve 22 by a key 26 which
which is received in a key way formed by slots
provided in the hub 29> of the worm gear and the.
reduced portion 23 of the sleeve. Supported on
the top end of the shaft I9 is a platform 21 which
has integrally associated with the under side
thereof a hub or collar 28 adapted to receive the
top end portion of the shaft I9, A -set screw or
bolt 29 which is in threaded engagement with the
hub 23 extends through such hub and engages
with the outer surface of» the shaft I9 to ñx the
platform in non-rotatable relation with respect
to said shaft. An electric motor 39 is mounted
on the platform 21 and is securely affixed to the
shaft I9 and is provided with ybrass bushings 46
which are ñxed to the inner surface of the end
portions of the sleeve in order to reduce the fric
tion between the sleeve and the shaft I9 to a
minimum. As before described, the shaft I9 is
ñxedly mounted within the sleeve I1 on the up
per end of the standard I2 by means of the set 45
screws or bolts 20, and the platform 21 is flxedly A
supported upon the top portion of the stationary
shaft I9 by means of the set screw 29.
The mo
tor 39 is preferably so positioned on the platform
21 with respect to the parts driving the sleeve 22 50
that the strains ‘produced in the platform 21 dur
ing the operation of the machinevwill be substan
tially Aequalized. ~
As is clearly shown in Fig. 1 of the drawings,
an" outwardly extending iiange or turntable 49 is 55
integrally formed with the lower end portion
of the rotatable sleeve 22 and rotates about the
shaft _I9 with said sleeve when the motor is op
erating. The turntable 48 is of such diameter
and is so positioned with relation to the upstand 60
ing iiange or circular rim- I6 on the’stationary
table I3„-that the. holders 49 for the containers
which are pivotally mounted at their inner ends
on supporting brackets positioned around ‘the
circumferential edge portion „of thè turntable.' `
are enabled to be rotatably supported on the rim
I6 intermediate of _their front and rear ends, as
shown in Fig. 2.

the other ends of such springs being supported
on similarly shaped projections 80 formed on the
outer end portions of the lever arms 68 and dis
65 posed oppositely of ‘the off-set portions 1| there

when the roller is riding on its upper edge, the 65
holder 49 is supported in a substantially horizon

holder 49 may be moved about the sleeve 22 with
out rotational'movement of -the shaft 51' and the
enlarged head 62 about their own axes. The rail
92 is positioned on the upper edge 81 of the flange
I6 so that such non-rotation of the shaft 51 and
the enlarged head 62 about their own axes occurs
during theperiod that the cam 85 is in engage

45 set portions 1I on the outer end portions of the
lever arms 68 in releasing position. The rail 9_2
is preferably sloped at each end to enable the
vprojection 93A to4 ride on and oil the rail without
any abrupt jerky motions. Integrally associated
50 with the cylindrical portion 54 ofthe bearing sec
tion 55 of the holder is an inwardly extending
portion or toe 94 which is adapted to operate as>
a stop to limit the upward movement of the holder
49 thereby preventing any jumping of the holder
55 as the projection 93 rides on or off the rail 92,
when the cam 85 engages with the disc member
. 82 or when the holder rides on or off ‘the inclined
edge 89 of the annular section I6.
‘
‘
It will be clear from the above that the con
60 tainers which have been packed with the desired
commodity and covered, are inserted in the hold
ers 49 at the position designated A in Fig.~` 2 of
the drawings and are removed from the contain
ers at the position designated B in said Fig. 2
65 after lhaving traveled almost completely around
the track formed -by- the upper edge of the ofîf
set portion 88 and the inclined edge 89. The ro->
tational movement of the turntable 48 is con
tinuous in the apparatus illustrated so that while
70 the apparatus is operating, the holders 49 are
interior surface of the bottom edge of the con
tainer, thereby tightly clamping the bottom edge
of the container against the annular wall of the
head portion 64. The rotative movement of the
arms 68 of the angular levers under the influence
of the springs 19 simultaneously causes the arms
61'thereof to rotate forwardly and force the pro
jections69 on the arms 61 against the- inner face
of the` plunger 10 thereby moving the plunger
head 10, the shaft 8| and the 'disc 82 forwardly.
Upon continued movement of the holder about
the sleeve 22 the projection 93 on the holder 49
rides\off the arcuately- shaped track 92 and en
ables the roller 6| to contact with the upper
edge of the off-setportion 88 whereupon rota
tional movement is imparted to the shaft 51, the
head 62 and the packed container about their 50
central axes.J Further movement of the table 48
brings the holder to the end ofthe off-set por
tion 88 and the roller~ 6| rides down the incline
which' connects the upper edge of the off-set por
tion with vthe inclined _edge 89 on the annular»
rim I6. During the period that the holder ia
ridingon .the inclined edge 89 it is tilted down
wardly to enable the upperl edge portion of the
container to dip in the sealing material contained
in the tank 96 to a sufficient depth so that upon 60
continued rotation of the vcontainer about its
axis as theV holder moves along the inclined edge
89 a thin even coating of sealing .material is
applied to the upper edge portion of the con
tainer and the outer .edge portion of the cover' 65
on such container thereby hermetically sealing
the contents of the container. Further rotation `
of the Ätable 4s causes the holder 4s to ride up
the inclined surface atthe `other end on the
inclined 'edge 89 and onto the upper edge of the I
off-set portion 88. The table 48 continues the
continually traveling around the track in a coun
ter-clockwise direction as viewed in Fig. 2, but ` movement of the holders in a counter-clockwise
it is within the contemplation of the invention
to move the various parts intermittently. In both
direction and during such movement the con
tainers are being continually rotated about their >
75 the positions designated A and B, the depending 'own axes, _such movement causing the sealing 75
