Improvements in Apparatus for Capsuling Bottles.
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 be particularly described and ascertained in and by the following
statement :-
The use of revolving rollers for capsuling bottles, as described in my Specification
No. 2550 of 1890, is attended with certain difficulties which it is the object of my
present invention to overcome, providing at the same time mechanical means for
subjecting bottles to the action of the rollers, as I shall describe referring to the
accompanying drawings.
Figs. 1 and 3 are plans.
Fig. 2 is a side elevation, and Fig. 4 is a longitudinal section shewing the rollers
and their holder and mounting.
Fig. 5 is a side elevation and Fig. 6 is a plan of the machine for capsuling.
Figs. 7 to 10 are side views of the rollers.
Referring to Figs. 1 to 4 each of a set of rollers E rotates on a spindle B, the
front end of which is free in a slot G of a plate C fixed to the tube A, the hinder
end being engaged in a sliding or fixed ring L which can be partly turned so as to
vary the position of the spindles B and consequently also of the acting surfaces
of the rollers E all the spindles being pressed against A by an india rubber
ring F.
Within the tube A is a sliding boss H pressed forward by a spring k and having
in front of it a disc J free to turn. A front plate D bolted to C has a central
hole through which the bottle neck can be passed. The rollers E are of special form,
the three shewn by Figs. 7, 8 and 9 are all similar and of these there may be four
or more in the holder as at Figs. 1 to 6.
There is only one, E' of the shape shewn by Fig. 10.
The rollers Figs. 7 to 9 are so arranged as only to act one after the other upon
the metal capsule, and as their rear parts are formed as conical frustra of equal, or,
as shewn at Figs. 7 to 9, of unequal length and form, they only effect a gradual
depression of the capsule on to the neck of the bottle. This is more particularly
the case after passing a swelling on the neck, when the depression of the capsule on
to the neck is effected very gradually firstly by the variously formed conical frustra.
and then by the pressing shoulders. The consecutive action of the pressing shoulders
of the rollers Figs. 7 to 9 is effected by shortening the rear, or lower end, and
extending the front or upper end, whereby the pressing shoulder is made to assume,
in the apparatus Figs. 1 to 4, a more and more rearward position, so that they can
only act one after the other upon the capsule.
The roller shewn at Fig. 10 acts after the others on the capsule, and in consequence
of the sharp form of its pressing shoulder, it presses the capsule perfectly close into
all the grooves and inequalities of the bottle neck.
The action of the apparatus is as follows:-
When the capsule is put on the bottle neck, the neck is pushed in between the
rollers E, but before they bear against the capsule its top is already pressed against
the disc J which without turning presses it against the cork and prevents the
capsule from turning. As the neck is pushed farther in, the rollers E act on
the capsule, the elastic band Fallowing them to accommodate themselves to the form
of the bottle neck. During this operation the rollers E, the protuberant parts of
some of which are farther back than those of the others as described act on the
capsule in succession, pressing it gradually around the bottle neck, while the roller E¹

page_text: Fig. 10 owing to the narrowness of its protuberance presses the capsule closely into
all the irregularities of the bottle neck.
On withdrawing the bottle neck from the rollers E, these as also the boss H with
its disc J are brought back into their original positions by the caoutchouc ring F
and spring k.
In order to effect the automatic capsuling of the bottles the apparatus shewn at
Figs. 5 and 6 has the set of rollers E arranged opposite a moveable slide M on
which is placed the bottle N to be capsuled, being prevented from rotating, for
example, by a loaded lever S. The slide M now has a to and fro motion_imparted
to it from the spindle O which effects the rotation of the roller system E, such to
and fro motion being effected by any known means such as a worm and worm
wheel P crank disc Q and rod R, whereby the bottle neck is consecutively
introduced into and withdrawn from the roller system.
Having now particularly described and ascertained the nature of this iuven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In apparatus for capsuling bottles the mounting of the rollers E on spring
pressed spindles B, the ends of which can be laterally moved for varying the position
of the acting surfaces of the rollers which operate consecutively on the capsule
substantially as and for the purpose set forth with reference to Figs. 1 to 4.
2. Constructing the rollers E in such manner that the pressing shoulders and the
rear ends thereof formed as conical frustra of equal or unequal height and form,
only act consecutively upon the capsule, whereby the latter is stretched in a very
gradual manner, so as not to be torn, while a roller E¹ with very narrow shoulder
finally presses the capsule into the smallest grooves and inequalities of the bottle
neck, substantially as described.
3. In apparatus for capsuling bottles such as herein described as also such as
described in the Specification to Patent No. 2550 of 1890, the use of a spring
boss H in the tubular roller holder A which is pressed backwards on the intro-
duction of a bottle neck, while its disc J effects the pressing of the top of the
capsule against the cork, and prevents the capsule from rotating, substantially as
described.
4. In combination with apparatus for capsuling bottles such as is referred
to in Claims 1 and 2, and such as described in the Specification to Patent 2550⁹,
the use of a slide M on which the bottle to be capsuled is placed and
which is moved so as to bring the neck of the bottle slowly between the
rollers E in order to be acted upon thereby, and then to withdraw the neck
from the rollers again, substantially as described with reference to Figs. 5 and 6
of the drawings.
