PROVISIONAL SPECIFICATION.
Apparatus for Fixing Capsules on Bottles.
I, CARL SCHERER of Langen, Hessen, Germany Manufacturer, do hereby declare
the nature of this invention to be as follows:-
For fixing capsules on bottles, machines, have heretofore been employed in which
the metal foil was pressed against the neck of the bottle by caoutchouc pressing
cheeks. With this arrangement a great many folds are formed in the metal foil, and
the capsule often fits very imperfectly against the bottle.
According to the present invention the working part of such apparatus is constructed
with a number of pressing devices which are pressed singly upon the neck of the
bottle, and which descend along the same in helical curves. By the axial component
of this helical motion, the metal foil is applied to the bottle neck with a considerable
elongating action; by the tangential component the formation of folds is prevented,
and a close fit is insured.
The apparatus consists for this purpose mainly of a rotating body which carries
the pressing devices. These devices exert an elastic pressure in the direction of
the axis of rotation and they are suitably arranged to admit the neck of the bottle
between them. The working parts may consist of rounded pins or studs, rollers,
cords, or bands which apply themselves with pressure to a portion of the circumference
of the neck.
According to one arrangement the apparatus consists of a hollow socket split
longitudinally to form three or more parts having spring action, the lower ends of
which have inward projecting ribs or swellings formed on them, which exert the
required pressure on the capsule as the socket is simultaneously pressed down and
turned round. According to another modification the socket has one or more sets of
sliding pins passing radially through it, the inner ends being rounded while the outer
ends are acted upon by springs, the pins being by preference arranged in helical lines.
The pins may have rollers at their ends to reduce the friction on the metal foil.
In order to render the apparatus suitable for different sized bottle necks, the upper
end of the split socket may have a coned screw thread formed upon it, on which is
screwed a correspondingly tapered nut, so that on screwing this downward on the
socket, the parts thereof will be sprung together so as to fit smaller bottle necks.
Or the sliding pins may be provided externally with heads that are pressed by the.
springs upon inclined surfaces upon a rotatable ring, so that in one position of this
ring the pins are drawn outwards to suit large necked bottles and in other positions
they move inwards to suit smaller sized necks.
According to another modification, the socket has three or more bands passing
transversely through it in such angular positions that they press against the neck of
the bottle passing through between them. These bands pass with their one end
through slots in the socket and have their ends connected to spring arms fixed on the
outer surface of the neck. According to another modification of this construction the
socket is replaced by three or more spring arms to which the ends of the bands are
attached.

page_text: 1, CARL SCHERER of Langen Hessen, Germany Manufacturer do hereby declare the
nature of this invention and in what manner the same is to be performed to he
particularly described and ascertained in and by the following statement :-
In fixing capsules on bottles, machines have heretofore been employed in which the
metal foil was pressed against the neck of the bottle by caoutchouc pressing cheeks.
With this arrangement, a great many folds are formed in the metal foil, and the
capsule often fits very imperfectly against the bottle.
According to the present invention, the working part of such apparatus is
constructed with a number of pressing devices such as are hereinafter described
which are pressed singly upon the neck of the bottle, and which descend along the
same in helical curves. By the axial component of this helical motion, the metal foil
is applied to the bottle neck with a considerable elongating action; by the tangential
component the formation of folds is prevented and a close fit is insured.
The apparatus consists for this purpose mainly of a rotating body which carries the
pressing devices. These devices exert an elastic pressure in the direction of the axis
of rotation, and they are suitably arranged to adinit the neck of the bottle between
them.
The working parts may consist of rounded pins or studs, rollers, cords or bands
which apply themselves with pressure to a portion of the circumference of the neck.
Figs. 1 and 2 of the accompanying drawings shewn in longitudinal and cross
section the simplest construction of the apparatus for the above described purpose;
the socket A is longitudinally split so as to form two spring-fingers having swelled
ends B which are made to press against the neck of the bottle when introduced into
the socket.
Fig. 3 shews a plan of an arrangement in which 6 studs B can slide radially in
holes in the socket A, these studs being pressed inwards by a caoutchouc ring F. The
studs may with advantage be arranged in a helical line.
In order to lessen the friction of the studs upon the tin foil capsule small rollers E,
Figs. 6, 7, 7 may be substituted. Fig. 6 shews a side view of the apparatus, Fig. 7*
a part sectional front end view, and Fig. 7" a back end view. The rollers E (which
may either all be in the same plane, or in a helical line) are mounted on small
spindles which are embraced by the caoutchouc bands F', the front ends of the spindles
being carried in slots in a disc fixed to the socket, while the rear ends are carried in
slots in a second disc attached to the rear end of the socket.
In order to enable one and the same apparatus to be used with bottles having
different sized necks the construction shewn in vertical section and end view at
Figs. 4 and 5 may be employed, in which the split ring socket A is formed with a
coned lower end having a screw thread, on which is screwed a correspondingly coned
nut G, so that by screwing this up or down, the size of the socket can be decreased or
increased at will.
Figs. 8 and 9 shew a vertical section and end view of a modification in which the
spring projections, studs, rollers &c., are replaced by bands or cords R which are
attached to the ends of springs, F, or, as in the modification shown in Fig. 10, they
pass through slots in the socket A, and have their one end attached to the socket, the
other end being connected in an adjustable manner to a spring F, whereby this
apparatus is also rendered applicable to bottles having different sized necks.
The fixing of the capsules is in either of the above cases effected by introducing the
bottle neck, with the capsule upon it gradually into the rapidly revolving apparatus so
that the projections, studs, rollers or bands are made to press the metal of the capsule
closely against the neck of the bottle.

page_text: Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, 1 declare that what I
claim is:
1. Apparatus for fixing capsules on bottles, consisting of a split rotating socket
having projections or swellings on its outer end, which, by the spring action of the
socket, are made to press the capsule against the neck of the bottle, substantially as
described with reference to Figs. 1 and 2 of the drawings.
2. Apparatus for fixing capsules on bottles, consisting of a cylindrical socket,
having radial holes, arranged either in one and the same plane or in a belical line,
through which slide studs the outer ends of which are acted upon by an annular
caoutchouc spring so as to cause the studs to exert an elastic pressure at their inner
ends upon the capsule, substantially as described with reference to Fig. 3.
3. In the arrangement referred to in the preceding claim, rendering the socket
adjustable for operating on different sized capsules, by splitting the socket longi-
tudinally and screwing a coned nut more or less on to a coned threaded part of its
base, the sliding studs being acted upon either by a caoutchouc spring or by blade
springs substantially as described with reference to Figs. 4 and 5.
4. Apparatus for fixing capsules on bottles, consisting of a cylindrical socket, on the
outer surface of which are mounted spindles carrying small rollers arranged either in
the same plane or helically, and projecting into the interior of the socket, the said
spindles being held in position by circular caoutchouc springs, and having their ends
guided in radial slots in discs on each end of the socket, substantially as described with
reference to Figs. 6, 7ª, 7".
5. Apparatus for fixing capsules on bottles, consisting of three or more flexible
bands or cords arranged so as to form a space between them into which the neck of
the bottle is introduced, the ends of such bands or cords being fixed, either with or
without adjustment, to springs carried by a socket or base, substantially as described
with reference to Figs. 8, 9 and 10.
