Anders Josef Jonsson, Linkoping, Sweden
Application October 9, 1935, Serial No. 44,157
In Sweden October 17, 1934
9 Claims.
The present invention has` for its object to
provide a bottle capping. machine of small dimen
sions and of a simple but effective construction.
It is substantially intended to be served or oper
5 ated by hand and it` is constructed either for
mechanical or for human driving power. The
former construction may also be automatized to
iva
the ring by the lever 4 via a roller ib` mounted be
tween the two parts of the lever.
`
Referring especially to the embodiment shown "ti>
in Figure 1 numeral 6 indicates the driving shaft,
'I the belt pulley of the shaft, 8, 9 a toothed gear
for transmitting a low speed to a cam disk shaft
As usual the machine is provided with a capping
head and a bottle supporting plate or the like
movable towards and away from the said head.
By means of the said plate the top of the bottle
is introduced into the head` in which the cap

,
20 capping head to the bottle supporting plate, and
vice versa, by means of which the effect of the
capping operation may be independent of the
distance between the capping head and the sup
portingl plate, i. e. independent of the heights of
the bottles.
_
Another object is to connect the said motion
transmission device to an operating member in
such a way that the plate may be raised and the
capping pressure applied to the cap and top of the
30 bottle by actuating, said operating member alone.
A further obj ect` is to arrange the machine parts
in such a way that the capping pressure is applied
to the bottles in a sensible manner inorder to
eliminate breakage of the bottles.
Still further objects will be described in the
following speciñcation.
,
Two embodiments. of .the invention- are illus
trated in the accompanying drawings.
Figure .1 shows one of them,.partly in section,
40 and viewed from one side, and
Figure 2 shows the other, also in side view.
Referring to both figures numeral 5 indicates
the frame of the machine, I the capping head, 2
a block, in` which the head is disposed, 3 is the
45 bottle supporting plate and 4 indicates a pressing
member embodied as a lever mounted on the block
and serving to apply the necessary closing pres
sure to the head. The lever consists, for example,
0f two parallel parts, which are rigidly united
‘with each other and located on either side of an
ear 4a of the block, the said ear serving as a
55
rubber and in the capping moment compressed by
a piston-like member 2I, which is pressed against
a certain extent.
One object of the invention is to provide an
adjustable motion transmission device from the
25
(Cl. 226-85)
IIJ, and Illa indicates a coupling device by means p
the wheel 9 may be coupled with the 10
In this machine the coupling is as usual
by means of a treadle Ißc, connected
coupling by a bar Ißb, and is retained
in operative position as long as the treadle is de- _
In the lower end of the sleeve is secured a bearing 4
I6 for a roller I1 contacting the cam disk I8.
The 20
said disk, being secured to the shaft I0, serves to
lift the supporting plate to the height required
for introducing the top of the bottle into the
head. A buffer spring Ma, within the sleeve I4
imparts a certain elasticity to the supporting plate
and determines the pressure acting upon the bot-~
tle from below, and at the same time it compen~
‘sates small variations in the heights of the
bottles.
For considerable variations in the heights of 30
the bottles the block 2 and therewith also the
head I may be set to various heights. Thus a
guide 35 for the block is embodied as a rack and
the block is provided with a pinion 36 meshing
with the rack so that the block may be raised 35
and lowered by turning a handwheel 3l ñXed to
the pinion. For fixing the block after each ad
justment the block is formed to a clamping sleeve
which surrounds the frame column 32 and is to
be fastened to the same by means of a screw 34
actuated manually by a key or lever 33. 'I‘he
lever 4 receives its working motion, i. e. its motion
downwards, from the shaft I0, for example by
means of a pam disk 25 via a drawbar 2E. The
lower end of the bar has a stirrup or the like 21 45
provided with a roller 28 contacting the cam disk.
The upward motion of the bar is eiîected by a
spring 26a. The bar is jointed to the lever by
means of a die 29, turnably secured to the lever
and loosely disposed on the drawbar. Above the
die there is a buffer spring 3B, a nut 3in1 and a
handwheel 3l screwed on to the threaded draw
bearing for the pivot 4c of the lever. The
capping head is of the known construction in bar. Thus the driving transmission from. the
which the cap is applied «to the top of the bottle lcapping head to the supporting plate may be
by means of an elastic ring 20, usually made of adjusted with respect to the distance between the 55

last mentioned parts and each desired fine ad
justment of the pressure acting upon the cap
and on the top of the bottle is obtained. The
spring 3l) is of importance for obtaining a
5 “smooth” or sensible closing pressure, which is
required especially when capping bottles of rela
tively large diameters in order to prevent the
“biting off” of the top of the bottle at its mouth.
The machine works in the following manner:
A bottle is placed on the plate 3 in the posi
tion determined by a centering member 38 and
at the same time the treadle is depressed, the cam
disk I8 lifts the plate 3 so that the top of the bot
tle is pushed into the elastic ring with the cap
loosely applied on the top either prior to or after
the introducing of the top into the capping head.
In the meantime the cam disk 25 has been turned
so far that the lever 4 begins to act on the member
2|, the ring 25 is compressed, the capping is ac
20 complished and the parts then reassume their
nuts 54.
When after the closing the handle is returned
the levers 4 and 5| reassume their initial posi
tions, the former by the actuation of one or more
resilient members, such as the elastic ring 20
When expanding, the latter by means of the weight
of the members hanging by the same.
20
By its simple construction this embodiment of
the machine may be manufactured in a suitable
size for mounting on a table or the like.
draw bar 26 may be replaced by a push rod, the
spring 26a, and the roller 28 being adapted to
act in the opposite direction to that intended in
Figure 1. If desired, the two cam disks i8 and
25 may each be replaced by a crank and the draw
bar 2t by a chain, wire or the like, in which case,
however, the
transmission
tion must be
spring 26a.
As will be
spring when used for returning the
parts displaced during the opera
arranged in another Way than the
easily understood the embodiment
described provides good possibilities as regards the
adjustment according to the heights of the bot
tles and as regards the fine adjustment of the
`capping pressure, besides which said pressure may
be regulated to one and the same strength in all
positions of the head and by a suitably dimen
sioned lever 4 becomes sufñcient without a great
load on the driving shaft.
50
of the cam disks 41 and the roller 53 are so ar
ranged relatively to one another that the lever
5| is actuated prior to the lever 4 so that first
the top of the bottle is pushed into the capping
head and then the pressure is applied to the cap
around the top of the bottle. In order to receive
a sufficient working movement bythe roller 53
the lever is curved upwards as is shown in the
drawings. The connection between the rod 50
and the tube i4 ~may be adjusted by means of
shaft l0, and the operation is repeated.
25 ure l, a two armed lever may be used and the

To take further precautions against the risk of
too hard a pressure during the capping operation
the belt pulley l is united with the shaft 6 by
means of a friction clutch. In the embodiment
shown the said clutch consists of three disks ¿33,
4| and 42, of which 43 and 42 are united with the
belt pulley by means of bolts, one of which, 43,
is shown in Figure l. The two disks 4t, 42 are
pressed against the third disk 4|, which is se
cured to the shaft 6 by means of springs, one of
which is found in Figure l and indicated by the
numeral 44. Each of these springs is guided by a
bolt 44a secured in the disk 4i? and set by means
of nuts 45. At a certain resistance against the
rotation of the shaft ß the disk 4l begins to slide
between the two other disks ¿i9 and 42.
The embodiment shown in Figure 2 is consider
ably simpliñed and it is arranged to be served and
operated by hand. Also here the block 2 may be
adjusted in vertical direction on the frame 5.
The lever 4 is depressed by means 'of a handle
46 via two cam disks 4l by moving the handle in

in many parts without departing from the spirit 25
of my invention.
