In accordance with the invention, the blank for

bottle, and'folding ?ngers actuated by movement
tabs to serve as staple-clinching anvils. The over

devices, which cut proper lengths of wire, form
them into staple shape having inwardly turned
partially clinched tines, and drive the staples
through the skirt tabs with their inwardly turned
tines engaging the upwardly turned edges of the
‘corresponding tabs, which are supported by the
bottle neck and accordingly act as anvils to com
plete the clinching of the staples between the 25
hood tabes and their upwardly turned edges. The ,
staples do not engage the neck of the bottle and
consequently cannot tear, scratch, or otherwise
mar the surface covering of ,the neck of the bot

leading pair of which is moved into‘ engagement
with the leading surface of the bottle B, whereby
the latter is positioned between these ?ngers and
the stationary pair of ?ngers 65 in accordance
5 with the movement imparted to the leading ?n
gers 65 by cam ‘I3. Each bottle B received by the
capping machine is ?rmly held against lateral

gers 65 while it is carried through the machine,

lease the bottle B after the hood has been applied

The contour of crown cam 48 is such that im
mediately after a bottle B is received by bottle
15‘ support 5I, the corresponding slide 58 is raised
so that the bottle B is brought into position for
cooperative relationship with the corresponding
capping head 45, in the manner illustrated in
' Figure 8. At approximately the same time, a
20 stationary cam ‘I5, mounted on a gear ‘I6 car
ried by the upper end of column 3|, actuates' a'
lever 11 mounted on the upper end of a pin ‘I8,
journaled in spider 48, as shown especially in
Figure 2. The lower end of pin 18 carries a lever
. 25 ‘I9, which normally holds pawl 88 in the dotted
position indicated in Figure 7.‘ Pawl 88 is con
nected to a centering mechanism supported by‘
bell 46, which includes a stationary ring 8I slid
ably mounting the ring gear 82, which carries
30 the pawl 88 and is urged in a clockwise direction,
as seen in Figure 7, by the plunger 83 engag
ing an-abutment 84 thereon under the. influence
of a spring 85 seated within a recess-in station
ary ring BI. Pivoted at equally spaced points on
2}; ring M are three centering ?ngers 86, the inner
ends of which are provided with pads 81 shaped
to the. contour of the neck of ‘the bottle adjacent
the bead D thereof, as is illustrated in_Figure 8.
The outer ends of centering ?ngers 86 are pro
40 vided with gear segments 88 which mesh with the
teeth of ring gear 82.
Asthe bottle B is elevated to the position illus
trated in Figure 8, cam ‘I5 releases lever ‘I9 so
that the spring'85 urges the pads 81 of centering
.15 ?ngers 86 into engagement with the neck of bottle
B so as to resiliently embrace the latter to center
the bottle with respect to the plunger 14 of the
head 45. The action of this centering mechanism
is illustrated in Figures? and 8, and is only mo
50 mentary, the cam 15 immediately returning lever
‘I9 to the dotted position illustrated in Figure 7,
whereby it reengages the pawl 88 to rotate gear
82 in a counter-clockwise direction and with
3
ing mechanism 91 through guides 96 to guides 96'
where they are advanced to properly, centered po
sition with respect to the mouth, cap, or upper end
of the bottle B by feed mechanism acting in
synchronism with the overhead feed mechanism.
These mechanisms operate after each hood-apply
ing operation to supply a hood blank E to the cap
ping head 45 for application to the next succeed
ing bottle, ‘the cap being also severed from the
strip by suitable mechanism to be described along , 10
with the hood blank feeding mechanisms. Suffice
to say for the time being that a hood blank E lies
in the guides 96’ in readiness for cooperating with
a bottle being elevated against its lower surface.
Normally splined in mesh with gear I81 and 15
journaled on spider 48 so as to roll around the
gear 16, as the spider rotates, are four pinions
I88 arranged to be clutched to and declutched
from gear ‘I6 for placing the mechanism of the
corresponding capping head 45 into and out of 20
operation. This pinion I88 is normally held in
raised position by coil spring I88’ encircling its
sliding shaft I28, and illustrated in Figure 9. As
cam 48 continues to raise bottle B, with the severed
hood blank E ,cl‘amped between the bottle top or 25
cap C and the rod ‘I4, the latter actuates lever I I9
pivoted on spider 48 and connected intermediate
' its ends to pinion I88, as is illustrated in Figures
1 and 9. . This pinion is slidable on jack shaft I28
and is moved downwardly by the action of rod ‘I4 30
into engagement with gear ‘I6 to drive gear M1;
at the same time roller I I9’ is raised from the
notch I23 of cam I22. Cam I22 holds lever H9
in the elevated position until gear I 81 makes a.
complete cycle, after which the roller. II9_’ drops 35
into the notch, disengagingpinion I88 from gear
‘I6 andlocking gear I8‘! until rod ‘I4 is actuated by
the next bottle.
The clutching action and conse
quent operation of the capping head 45 are delayed
‘until the proper, time by cam I22, which is when 40
the bottle has been elevated by cam 48 to a posi
tion near the‘end of its stroke.
The inner end of lever H9 is extended and
carries a roller I89’ cooperating with stationary
cam I89 mounted on gear ‘I6, as is illustrated in 45
Figures 1 and 4. This cam is opposite the notch
I23 in cam I22 and insures that, after completion
of each operation of the capping head, roller
“9' ‘drops into the notch I23 of cam I22 to dis
engage gear I88 from gear-I81. Accordingly, if
spring I88’ should fail at any time, due to break
age or the like, cam I89 will disengage gear I88 at
the proper time to prevent the capping head 45
from continuing to operate out of synchronism

if no bottle is in position on bottle support .5I,
so that the bottle B may be elevated further.

wardly against the inner surface of the tab 89.
(55 Interposed between the broad tabs 89 are short
and narrow tabs 9| which are connected to the
broad tabs 89 by gussets 92, while the octagonal
center 93 of the cap E, de?ned by scored creases,
is of a size corresponding substantially to the
70 mouth or crown cap C of the bottle B; Preferably
one of the tabs 89 is provided with a ?nger piece

moves up and down in response to actuation
jointly by cams 48 and I46.

Located within a recess in rotating sleeve I24,
but stationary with respect thereto, is an inverted

of tube I49.
Seated in the groove of collar I58 of tube I49
are the ends of several bell crank levers, alternate
ones of which are longer than the remaining
15 levers.
Long bell crank levers I59, of which
there are four in number,_ are adapted to co
operate with long tabs 89 of the hood blank illus
trated in Figure 6; whereas the short bell crank
levers I68 are adapted to cooperate with the short
20 tabs 9| of the hood blank, as is illustrated in Fig
ures l2 and 13. These bell crank levers are piv
oted on frame I48, as is illustrated in Figures 9,

?ngers I62 follow the movements of long ?ngers
I64 and fold the short tabs 9| downwardly to '.
overlap the edges of the adjacent long tabs 69,
as is indicated in Figure 13.
‘
After the hood skirt has been formed around 10
the neck of the bottle by the interfolding of
the tabs of the hood blank E, in the manner
described, the ?ngers continue to hold the skirt
tightly around the neck of the bottle while the
stapling operation takes place.
Four stapling devices are provided for each
hood-applying head 45, and one of these stapling
devices corresponds to each of the four short
tabs 91 of the hood blank E. , These ‘stapling
devices are indicated at I18 in Figures 1, 8, 9, 20
and 15, and are illustrated in detail in Figures
16, 17, 18, and 19. Each stapling device in
cludes~ a block or base “I, secured to the bell

beneath the end of corresponding short folding
?nger I62, which is made short for the purpose
of providing the necessary clearance for the
stapling device jaws I96, as is illustrated in Fig
ures 1 and.13. As is indicated in Figure 15, the
long folding ?ngers I60 lie between the stapling
device I10 and do not interfere with their opera~
tion but continue to hold down long tabs 89 dur
ing the stapling step. The four jaws I96 of the 10
corresponding four stapling devices simultane
ously engage the corresponding hood tabs 9I so
as to substantially encircle the neck of the bottle
B in the manner illustrated in Figure 15, where
by the skirt of the hood is moulded into 'close
conformance with the neck of the bottle before
the partially clinched staples are driven through
the hood to tie it securely in this condition.

of which lie in the grooves in the inner walls of
the slide I89, as is illustrated in Figure 20. The

of the advancing driver I90, which then holds
the rear end of and advances the staple further
along the grooves in the inner walls of slide I89
into the bending jaws I96, in the grooves of which
the tines of the staple are ?ared outwardly, as ,
shown in Figure 21.
.
Extending upwardly between the jaws I96 is
the nose I91 of a ?nal-forming, spring-pressed
40 arbor I98, which is'piv'oted at I99 in the block
I H for downward swinging movement. The nose
of the arbor I91 conforms to the outwardly ?ar
ing grooves of the jaws I96 and the tines of the
staples are driven between these jaws I96 and
45 the nose of arbor .I91 so that they are spread
apart and the tips thereof are simultaneously
curved toward each other. The cam-action of
the advancing driver forces the arbor I91 from
between the jaws I96 and the freed staple is ad-'
50 vanced by driver I90 between the narrower tips
of jaws I96, which accordingly again bend the
tines of the staple into substantially parallel re
lation with their tips curved toward each other in
partially clinched condition before being pre
sented to the hood, as is illustrated in Figure
22 at S.

As the slide_l89 advances, a spring 200 car
ried thereby is pressed against a pawl 20I, pro
' jecting into the wire thimble I81 (Fig. 18) to
60 cause it to clamp the unsevered length of wire
during the severing operation in order to pre
vent it from springing back because of its nat
ural resiliency. Accordingly, the wire will not
be short when next advanced by the feed rolls
I16, I19, as would be the case if the wire had
retracted. Because of this wire-gauging ar

sponding downwardly folded narrow tab 9I at
the relatively sharp angle indicated in Figure
23. Immediately below the narrow tab III are
the abutting edges of the adjacent long tabs 09,
,
From the position indicated in Figure 22, sta
ple driver I90 drives staple S through‘the‘ rela
tively non-rigid layers 9| and 89 of the hood
skirt without de?ecting the tines in any way, as
is illustrated in Figure 23, until the inwardly
turned tips‘of the staple tines engage the up
turned tab edges 90, which, because they are
rendered ?rm by being immediately backed by
the rigid surface of the bottle B, act as anvils and
de?ect the tips of the tines inwardly toward each 40
other. This inward de?ection of the tines is in
duced by the curvature of the tips thereof pro
duced jointly by arbor I91 and jaws I96, these
tips sliding on but not penetrating the surfaces
of the corresponding tab edges 90 as they engage
the ?rm smooth surfaces thereof.
Further movement of the driver I90 causes the
tines of the staple to clinch completely to the ,
position indicated in Figure 24, the edges of the
tabs 89 being drawn toward each other by the
movement of the staple tines so that the skirt
of the hood tightly embraces the neck of the
bottle B in the manner illustrated in Figure 25,
and cannot be withdrawn over the ?aring bead
D without mutilation, so that any tampering
with the hood can be readily detected. Accord
ingly, with the hood applied by the machine of
this invention, a tamper-proof package ‘is pro
duced.
Displacement of , the hood may be read
ily accomplished by tearing it by liftingthe ?n
ger-piece 94 shown in Figure 6.

The simultaneous driving of the four staples
S which tie the hood to the bottle is not accom
panied by impact but can be described more ac
curately as being a pressing action, the tines of 65
the four staples penetrating the skirt of the hood
rangement, the tines of the staple, instead of ' simultaneously and then being de?ected by en
gagement with the upturned tab edges 90 in the
being of different lengths, are of the same length
and the staple can be driven evenly/and accu
70 rately in consequence.
'
The jaws I96 are also slidably mounted in the
‘block or base I1I of the stapling device, and as
the slide I89 advances, ' lateral extensions 202
thereof engage the rear ends of the jaws I96 and
project them into engagement with the lower end
manner described, so that no cracking or other
' injury of 'the bottle neck can take place nor is 70
the surface of the hood skirt mutilated or marred _
by engagement between it and the staplingde
vice jaws I96.‘ Furthermore, in order to. accom
modate bottles having oversized necks withoutvv
breaking them 'orhthe stapling devices, the link

I93, which actuates staple driver I 99 is made
resilient by a saw cut I99’, so that if the driver
I99 engages an oversizcd bottle neck, the link
I93 will shorten automatically to compensate for
the’oversize, returning to normal length imme
diately after the staple-driving operation be
cause of its natural resiliency.
Also, because the tines of the staple are ?nally
clinched behind the upturned edges 99 of the
hood, they cannot engage and thus mar, scratch,
rotates step-by-step in the manner described.
In addition to the mutilated gears I25, I26, I27,
and I 28, sleeve I29 carries gear I29 and crown

After the stapling operation is completed, cam
20 98 again lowers the hooded bottle B from out of
the capping head and transfer mechanism, not
shown but similar to transfer mechanism 58, re
moves the completely hooded bottles from their
supports SI and transfers them to a conveyor or
25 the like, not shown.
As the hooded bottle is withdrawn from the
capping head 95, the paper strip 95 is advanced
to provide the head with a new hood blank E
in readiness for the next hood-applying opera
30 tion, and this mechanism will now be described.
As was previously mentioned, the hood blank
strip 95 is fed downwardly through guide 96 by
an overhead intermittent feed mechanism to a
second intermittent feed mechanism which op
The overhead
35 erates in synchronism therewith.
Paper feed slide I36 carries pivoted feed ?ngers
I31 which engage the hood blank strip 95 be
hind the laterally projecting tabs 9I, illustrated 20
in Figure 6, so that when the slide I36 is recip
rocated by’ the crank pin I32, as is permitted by
the sliding connection between lever I39 and
slide I36 (Fig. 10) in a manner readily under
stood, the hood blank strip 95 is advanced one 25
hood blank length in guides 96’ into the center V
of the head 95 in position for cooperation with
the next bottle to be ?tted with the hood. The
feed ?ngers I91, after advancing hood blank
strip 95, lodge behind the rearward edges ofthe 30
lateral tabs 9|, so as to prevent the hood blank
strip from springing backwardly as a result of
its natural resiliency, so that the hood blank is
not only advanced to proper position by the
?ngers I31, but is also held in that position by the 35

As each leading hood blank E is advanced into
position for alignment with the top or cap C of
the next bottle which is to be provided with a
hood, it is automatically severed from the hood 50
blank strip 95 by a moving cutter blade I38, car
the lower end‘of shaft IDI, as is illustrated in
Figures 4 and 5. The other end of double lever
I99 carries a cam-following roller I95 which en
50 gages the edge of a disc cam I06 mounted on the
upper surface of a gear IU'I driven by pinion I99
in the manner described, so that pawl I 93 ad
vances reel 91 a su?lcient amount to feed the
.55
strip 95 the length of one hood blank E through
guide 96 toward the corresponding capping head
95 for each revolution of spider 59. Since there
are four capping heads 95, four hood blanks are
‘fed toward the corresponding capping heads dur
ing each complete revolution of spider 49.

The magazine 98 contains four rolls I ID of hood
blank strips 95, one of which leads to each of the
four reels 9? over an idler pulley I I I, as is illus
trated in Figure 3.‘ The idler pulley III is car
ried by levers IIZ pivoted on the shaft of reel
65
Ill and urged in a counter-clockwise direction, as
seen in Figure 3, by spring H3, interposed be
tween one of the levers H2 and the magazine
99, so as to take up slack in the strip 95. In
order to hold the hood blank strip 95 on the reel
70 9'I, an arcuate guide “5 partially encircles the
reel 9? and is carried by the lever H6 pivoted at
IN on the top plate 99 and adjustable about its
, pivot ill by a set screw II 8, engaging the maga
75
zine 98. The reel 91 is provided with spaced sets
strip 95 amounting to one or two hood blanks E
in length to prevent tearing of the strip in the
event that there are any irregularities in cutting 45
p
'
ried by the bell 96 and cooperating with the
stationary cutter blade I39 (Figs. 8, 9, and 10).
Moving cutter blade I99 is actuated by a rod I40
having a roller I9I at its upper end which fol 55
lows the contour of revolving cutter cam I39,
which is so arranged that, as the leading hood
blank of the hood blank strip 95 is advanced and
held in proper position with respect to the bot
tle B by the feed ?ngers I31, it raises moving cut
ter blade I38 to sever the hood blank from the
hood blank strip 95, the movement of the cut
ter being synchronized with the movement of
the hood blank strip 95. A spring-pressed plung
er I82 carried by moving blade I38 clamps the
hood blank strip against the upper blade I39,
while the blank is being severed therefrom. The
cutting of the hood blank E which is retained in
the guides 96' is the last operation of the stapling
head 45 after the stapling operation and places
the head in readiness for the next stapling opera’
tion.
Although the operation of the machine of this
invention will be readily understood from the
foregoing description, it will be reviewed. Bottles

B, either wrapped or unwrapped, are transferred
one at a time by the transfer mechanism 58 from
a conveyor 59' or other machine to the bottle
supports 5| of the hood-applying machine, as is
illustrated graphically in Figure _1. The hood
applying mechanism rotates continuously in one
direction about its center column 3|, and as it
rotates the bottle supports 5| are elevated and
lowered by stationary cam 48 which the follower
10 rollers 49 of the bottle supports 5| follow.
' The bottles B, held securely on the correspond
ing bottle supports 5| by ?ngers 65, are accord
ingly ?rst elevated by cam 48 into engagement
with a severed hood blank E underlying the
15 clamping disc I41 on the lower end of rod 14 in
the guides 96'. When the bottle B reaches this
elev ited position-it is momentarily held station
ary by cam 48, while it is centered with respect
to the hood-applying head 45 by centering mech
20 anism illustrated in Figures '1 and 8, which is op-'->
erated by lever 19 actuated by stationary cam 15
around which the cam follower 11 rolls as the
hood-applying head 45 rotates. Actuation of the
centering mechanism lever 19 results in the mo
25 mentary release. thereby of spring 85 which urges
the centering ?ngers '86 resiliently around the
neck of the bottle B, to center the same in the
manner indicated in Figures '7 and 8, whereupon
cam 15 again actuates lever 19 to withdraw cen
30 tering ?ngers 86 for further elevation of the
bottle B.
Further elevation of bottle B with the hood
blank E-clamped between its mouth, top or cap
C and clamping disc I41 elevates rod 14 to swing
35 the end of lever I43 into engagement with cam
I46, the contourof which is like that of cam 88,
so that as the capping head 45 rotates the bottle
is held securely upon its support 5|. This sup
port 5| is not rigid but will recede in the event
40 that a taller bottle than usual is placed thereon,
so that there is no danger that the bottle will be
broken by being clamped between in?exible sup
ports.
‘
Although the centering device operates in any
event, the remainder of the hood-applying mech
anism of head 45, including the hood-blank feed,
hood-blank severing and stapling mechanisms,
does not. operate if a bottle is not in position on
the corresponding bottle support 5|, the pres
ence of a bottle being necessary to initiate oper
ation of these mechanisms. Thus, the elevation
of the bottle B beyond the place where it picks
up the hood blank E, effects the engagement of
pinion I88 with gear I81 at a time determined by
delayed-action cam I22, which time is after the
?rst hood blank E h_as been folded around the
neck of the bottle, prior to the stapling opera
tion controlled by pinion I88.
The steps of the hood folding operations are
60 illustrated graphically in Figures 8, 12, and 13,
and are jointly effected by the movement of the
bottle and by cam I51, the latter controlling the
' folding under of the ends 98 of the long tabs 89
by means of hook ?ngers I65.
65
As indicated in
Figure 8, the depending folding ?ngers I62 and
I64, in their original position, fold down the re
spective short tabs 9| and the long tabs 89
toward'the neck of the bottl , the action of the
?ngers I64 preceding becauge they are longer,
so that the long tabs 89 ar .folded down ?rst
with the edges of the intermediate short tabs
overlapping and being guided straight by the
?anges |6| in the manner illustrated in Figurev
14.
.
However, before these ?ngers are moved by
further elevation of the bottle, the hook ?ngers
I65 are actuated by cam I51 to move inwardly
from the position shown in solid line in Figure 8
to the dotted line position to engage the lower
edges of the long tabs 89 in the hook ?nger slots
I69 and fold the edges 98 upwardly as seen in
Figure 12.
Immediately thereafter, as the hook ,
?ngers I65 are being withdrawn by cam I51,
bottle B raises rod 14 so that disc‘ I41 engages
and elevates collar I58 to cause the latter to 10
swing the bell cranks I59 and I68 about their
stationary pivots to move the respective long and
short ?ngers inwardly so that they press the
corresponding long and short tabs 89 and 9|
against the bottle neck with a resilient pressure 15
provided by the natural resiliency of long ?ngers
I64 and by springs I63 of short ?ngers I62. This
arrangement also automatically compensates for
variations in size of the bottle necks. Further
elevation of the bottle causes the folding ?ngers 20
to smooth the corresponding tabs into a skirt
closely encircling the neckof the bottle, the long
?ngers I64 creasing the upwardly turned edges
98 of the long tabs 89 against the bottle neck in
the manner illustrated in Figure 13, which also 25
shows the hood in position for stapling.
The pinion I88, being normally in splined en
gagement with stationary gear 16, rolls around
the latter as spider 48 rotates and accordingly
drives corresponding gear I81, the four pinions 30
I88 coming into action successively in a manner
readily understood. This rotation of gear I81
effects rotation of mutilated gears I25, I26, I21
and I28, which initiates the simultaneous opera
tion of the corresponding four stapling devices
illustrated in Figure 15. Each of. these devices
feeds wire stock from reel I83 through tube I86
across slot I88, which acts as a gauge, while
clamp 28I holds the wire as it is cut off by and
bent into U-shape around anvil I95 by slide I89, 40
as is illustrated in Figure 20.
The anvil I95 is
then forced out of the way by driver I98, which
advances the staple blank into grooves formed
jointly by-jaws I96 and arbor I91 so that the
tines are spread apart although the tips of the 45
tines thereof are bent toward each other in the
manner illustrated in Figure 21. Arbor I91 is
then forced downwardly out of the way by the
cam surface of driver I98, as is indicated in Fig
ure 19, and the driver I98 advances the staple 60
blank between the con?ning jaws I96 which
bend the tines of the staple blank back into
parallel relation, with the tips thereof being bent
toward each other in partially clinched form, as
55
is illustrated in Figure 22.
During the last stage of the staple-forming
operation, the jaws I96 are projected forwardly
so that they engage the short tabs 9| of the hood
skirt, the four jaws closely encircling the neck
of the bottle to press the skirt tightly around it. 60
The folding ?ngers I62 which hold the short tabs
9| down are made short to accommodate the
stapling jaws I96 beneath them, while the long
folding ?ngers I68 lie between adjacent stapling
65
devices as is illustrated in Figure 15.
‘Althoughthe jaws I96 of the stapling device
are postively projected forwardly ?rmly against
the bottle necks, they are not rigid, but are al
lowed a su?icient degree of resiliency to accom
modate oversize bottle necks without breakage. 70
This resiliency is provided by the slot I93’ shown
in the jaw-advancing link I93 in Figure 17.
The preformed partially clinched staple S is
presented to the lower end of the short tab 9|
which overlaps the. upwardly turned edges 98 of 76

several tabs, staple, and stapling mechanism be
- fore-driving being illustrated in Figure 22.
As
was previously explained the partially clinched
tines of the staple S are forced through the rela
tively non-rigid short tab 9| and abutting under
lying edges of the adjacentlong tabs 89 until
they engage the ?rm upturned edges 90, which,
\backed by the bottle neck, act asv anvils to turn
10 the partially clinched tips of the tines toward
each other to complete the stapling operation, as
is illustrated in Figures 23 and 24, the staple tines
being ?attened between the long tabs 89 and their
upwardly turned edges 90 in the manner illus
15 trated in Figures 24 and 25.
It will be observed from Figure 23 that the tips
of the staple tines lie within the angle de?ned by
the radial lines drawn from .the center-of curva
ture of the bottle neck to the ends of the cross
20 bar, head, or widest part of the staple S, i. e., the

After completion of the stapling operation, the
jawsv I 96 are withdrawn and cam 48 lowers the
40 hooded top of the bottle out of head 45 and it is
, transferred from the bottle support to a conveyor
or the like by a transfer mechanism similar to
mechanism 58 and cooperating with cam 13 which
45
opens the gripping ?ngers 65 at the proper time
to release the bottle for transfer by the gripping
?ngers of the transfer mechanism.
As the bottle is withdrawn from the capping
head 45 the hood blank feeding and severing
mechanism comes into action, being driven by
50 pinion I08 in synchronism with the overhead
hood-blank feeding mechanism, and advancing
the hood blank strip 96 with slide I36 and ?ngers
I31 to place a hood blank E in guide 96’ in posi
tion for engagement by the mouth or cap C of the
55 next bottle to be hooded. After the leading hood
blank E is positioned, the cutter cam I30 comes
