The capping head barrels 6'! and 68, respec
tively, are each provided with a pair of slides
I95, see Figs. 5, 21, which are mounted for recip
rocating horizontal movement through slots in
the side walls of the barrels into position to close 25
the barrels below the openings ‘I1 and 19. The
slides I95 are pivotally connected to bell cranks
I96 and I9‘! which are pivotally supported at I98
to bracket-I98a. The other arm of each bell‘

While in its elevated position. 7 The capping head head barrels are in their elevated position the
barrel 68 is adapted to be, fed with a container
35 top b while ‘in its elevated position. The capping
head barrels are then lowered into position, see
Figs. 20 and 21, to deliver» the grease plunger and
container top, respectively, upon the containers
A. The barrels are guided by thecenter column
40 4 and key I25 to be later described.
Plunger and container top magazines
Plungers a are fed into the plunger barrel 61'
from a magazine 12, see Figs. 3, 14 to 20, inclusive.
45 Container tops b arecfed into. the capping head
barrel 68 from a magazine 15. 'I'h_'e_magazines
‘I2 and 15 are supported in an inclined ‘position
by means of frame pieces ‘I6, which in‘ turn‘ are
supported by the table I. The magazines ‘I2 and
50 ‘I5 are provided with discharge outlets which open
into inlet openings 11 and 18 in the barrels 61
and 68 respectively, see Figs. 5 and 6. The de
livery ends of the magazines ‘I2 and 15 are semi
c‘rcular in shape as shown in. Figures‘ 3, 15, 17
55 and 19 and furnish a rest or slide for the‘ grease
plunger or can tops for the longest possible time.
The plungers a and container tops 27 are fed
from the magazines ‘l2 and ‘I5, respectively, posi
tively through the inlet openings TI and ‘I8into
60 the barrels 61 and 68 through the following ar
rangement of parts. The spider prongs 9 during
each stage of rotation of the spider engage a
pawl 89, see Figs. 1, 3 and 7, and movegthe pawl
89 in partial rotation; The pawl 89 is non-ro
65 tatably carried by a shaft 8|, which in turn-is
supported by a suitable frame 82 carried by the
table I. The shaft 8| carries a crank83 to which
is attached a chain 84, which passes around a
Wheel 85. The wheel 85 is rotatablymounted in
a frame 86, extending from the ‘under surface of
the table I. The chain 84 is attached to an arm
81 which is non-rotatably mounted upon a shaft
88. The shaft 98 is non-rotatably connected to
_ a link 89.
The link 89 is
pivotally connected to
76 a link 99 which in turn is pivotally connected to
slides I95rextend into ‘the barrels to form a'sup
porting surface for the bottom cap and plunger
which slide into the barrels. Only one plunger 35
or one container cap or top‘ can slide into'each
barrel, the others being held back by the trigger
I94. Each trigger I94 is provided with a head
II2 which protrudes through a slot in the bot
tom' of the magazine, into position to engage the
bottom plunger or container top respectively.
Each trigger I94 is pivotally supported at II4
upon the frame I57 ‘of the machine, a helical
spring II5 normally functioning to maintain the '
head of the . trigger projecting into the maga 45
zine.
The placing ?ngers 92 and 95 are'mounted on
the magazines ‘I2 and 15. The arms 9| and 93
work ‘through two guides, one fastened on each
side of the magazines. The guides are provided
with the offset slots I99 so that when the ?ngers
are pulled downward they are forced down into
the bottom of the magazines ‘I2 and ‘I5. When
the ?ngers are at the bottom end of their travel,
the ends of the ?ngers are extending slightly 55
past the inside of the barrels 61 and 68 of the
capping head. At this point the ?ngers go out
of control of the spacing spider and a spring II‘I
secured to the magazine and link 89 snaps the
?ngers into their elevated position. While each
?nger arm is coming back to its starting and
resting position the offset slot I99 in the guides
forces the ?ngers up out of the magazines 12
and ‘I5. The placing ?ngers come in contact
with only one plunger and one top. The placing 65
?ngers'place the plunger or top correctly in the
barrels of the capping head, should they not slide
to the proper place of their own weight.
Capping head operation
The capping head barrels 61 and 68 carrying
a plunger a and a container top b respectively
are lowered from the position shown in Fig. 1 to
the position shown in Figs. 20 and 21, in which
the barrels are telescoped over the containers.

and 6K are tapered internally as indicated at l26.
in .Figs. 14-16 and 18. Consequently, when the
barrels descend upon containers which are not
perfectly cylindrical, the barrels shape the con
tainers to a perfect cylindrical shape and thereby
l0. insure the correct ?tting of the plungers and
'
the. plunger and top as follows, see Figs. 20 and
211. ‘The. rolls H6 of the bell cranks, I05 and I161
are moved downwardly upon descentiof the pis
tons by engagement with cam surfaces H0 upon 10
tons.
The capping head is operated in vertical re
ciprocating movement through the following
arrangement of parts, see Fig. 13.~ The main

lever I29. The opposite end of the lever is. piv
otally supported at I3I' from a support 532 de
The
piston head I583. in the container topping barrel
88 is flat while the piston head I 50‘ in the plunger
placing barrel has a projection I12; of sui?cient
pending from the table I. A lift rod I64. is
20 connected to an intermediate portion of the lever
I29, and to an intermediate portion of a. lever
I36. The lever I36 is pivotally supported at one
length to press the plunger down in the can to‘ 20
its proper position.
- Subsequently to positioning the plunger-and
top, the piston actuating cam l2’! lifts the cap
end by a bracket I31 projecting upwardly from
the table I. The lever I36 is pivotally connected
25; at I39 to the capping head 65.
At thev time the placing ?ngers 92 and 95 are
snapped back into their withdrawn position, the
ping head to its elevated position. Simultane
ously the triggers IM are released so that the
trigger heads rise in the magazines to a position 251
to block o? descent of all of the plungers and
tops in the magazines. except the ones‘ that are
cam I2‘! is withdrawn from the cam follower
I28, permitting the capping head to descend
30~ by its own weight into the position illustrated in
Figs. 20. and 21. This movement lowers the bar
rel slots .11 and ‘I8 with respect to the delivery
openings of the magazinesjwhich are closed by
the outer surface of the barrel walls‘;
As the barrels B1 and 68v descend, the grease
plungers and container tops are permi ted to
slide downwardly in the magazines, as follows:
The barrels 6'! and 68 eachcarry an arm M4‘,
see Figs. 1 and 20, to each. of which is secured
40 a hook-shaped member I45. When the barrels
descend, the hook-shaped members’ I45 engage
a pin I46 upon thetriggers H34 andpull the ends
of the triggers downwardly out of the way of
the-plungers and tops- in the magazines. Conse
quently, all of these plungers and container tops
in the magazines slide down, with the bottom
plunger and top coming to rest against the out-.
side wall of the barrels G'l and" st respectively. . I
Positioning pistons
Pistons are provided to positively position the‘
grease plunger and top upon the container.
Each piston comprises a piston head I58, see Figs.
5, 6, 20 and 21, which‘ is disposed within the
55 barrels 61 and 68. Each piston head is. sus
pended by means of a piston rod I5! and link
I52. Each link I52 is providedowith spaced rolls
I53 forming a. slot through which passes a lever
I54. The lower roll E53 is‘mounted on a carriage

The‘ slides: I55 of each barrel are withdrawn.
laterally fromthe barrel to: permit descent of
I55 inside the piston IBI. A spring IBM is lo
cated under this carriage with a tension greater
than is necessary to put a top on a can, but not
enough to crush the can, if the can is‘ a little‘
longer than necessary. The lever .I54'can come.
65 down to its extreme lower position without crush
ing the can. One end of the lever I54 is pivot
ally supported at I58 by means of a support I51.‘
secured to the table top I. The other end‘ of the
lever I56 is driven by reach rods. I59.‘ Each reach
rod I59 is connected to across rod I60, which, in
turn, is pivotally connected to one end of a lever.
I62, see Fig. 12. The lever I52 is pivotally mount
ed at I63 upon. a support I64. The-other end
of the lever I62 carries a cam follower i '56 which
is engaged by a cam I61 non-rotatablymounted
resting against the outside wall of, the magazines.
