Year: 1879

Patent Solicitors, at Frankfort on the Main, in the Empire of Germany, for
the Invention of "IMPROVEMENTS IN CAPSULING MACHINES." A communi-
cation from Franz Fehr, trading under the Firm of "Wiesbadener Staniol &

PROVISIONAL SPECIFICATION left by the said Frank Wirth at the Office
of the Commissioners of Patents on the 24th March 1879.

This Invention relates to an improved hydraulic machine for putting capsules
upon bottles and similar articles, and comprises various details of construction.
In a machine constructed according to the said Invention, the upper working of
a plunger is effected from below by a lever being depressed from above. There is
also an elastic chamber with four ribs, and made of semi-hard india-rubber
strengthened with linen or canvas made up in the same, this chamber being designed
to receive the neck of the bottle or similar article. Elastic chambers made according
to this Invention, when under pressure, fold together, and this gives the capsule
such a shape that there are four points projecting therefrom, and the bottle or
other article has only to be turned a little when the said projecting points or pieces
are folded over.
For pressing on tin foil I make use of a smooth elastic chamber not provided
with ribs.
Another improvement consists in providing a screw in connection with the end
of first named elastic chamber, the head of said screw being turned out to receive
the head or top part of the bottle or cork, as the case may be;. this prevents the
capsule from slipping or going on sidewise.

FRANK WIRTH, of the Firm of Wirth and Company, Patent Solicitors, at Frank-
fort-on-the-Main, in the Empire of Germany. 'IMPROVEMENTS IN CAPSULING
MACHINES." A communication from Franz Fehr, trading under the Firm of
"Wiesbadener Staniol and Metallkapsel fabrik A. Flach," of Wiesbaden, in the
Empire of Germany.
This Invention relates to an improved hydraulic machine for putting capsules
upon bottles and similar articles, and comprises various details of construction as
herein described.
In a machine constructed according to the said Invention there is a plunger
whose upward working is effected from below by means of a lever or handle, which
is depressed from above. There is also an elastic chamber with four ribs and
formed of semi-hard india-rubber, strengthened with linen or canvas made up in
the same, this chamber being designed to receive the neck of the bottle or similar
article. Elastic chambers made according to this Invention, when under pressure,
fold together, and this gives the capsule such a shape that there are four points
projecting therefrom, and the bottle or other article has only to be turned slightly
when the said projecting points or pieces are folded over.
For the application of tin foil I make use of a smooth elastic chamber not
provided with ribs.
Another improvement consists in providing a screw in connection with the end
of the first named elastic chamber, the head of the said screw being turned out to
receive the head or top part of the bottle or cork, as the case may be; this device
.prevents the slipping or sidewise putting on of the capsule.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front elevation of a machine constructed according to my
Invention.
Figure 2 is a longitudinal section; and
Figure 3 is a vertical section of the same.
Figures 4, 5, 6, and 7 shew the said india-rubber chambers.
Figures 8, 9, 10 are diagrams of capsules in different stages of compression.
Figure 11 is an elevation partly in section of the said capsuling machine mounted
on a pedestal or pillar.
Figure 12 is a top view of Figure 11.
Figures 13 to 24 show some of the kinds of bottles which can be capsuled on my
machine.
The construction and method of working the said machine are as follows, that is
to say:-
When the handle E is pressed down the plunger F is forced into the chamber B,
driving the water into the chamber A, thus compressing the elastic chamber O into
which the neck of the bottle is inserted.
The lever E is connected by the joint-piece K and pivots L to the machine. The
plunger F is provided with a collar G to prevent the escape of the liquid contained
in the part H around the former. The liquid contained in the machine can be
either water, glycerine, or other suitable substance, the said liquid being introduced
into the chamber B by a hole in the top, which is afterwards stopped by the plug J.
The said machine is attached by means of an arm M and clamp screw N to any
suitable support where it is to be operated as described.
The elastic chamber O is held in its place by the face plate D in front, and by
the screw C at the back of the machine. The head of the screw C is recessed or

page_text: turned out to support the end of the bottle. By the use of this screw the elastic
chambers will be much more durable than when the said screw is not used.
For my improved machines I use two kinds of elastic chambers represented in
Figures 4 and 5, and in Figures 6 and 7. The one represented in Figures 4 and 5 is
provided with four ribs p, the semi hard india-rubber being strengthened with linen,
canvas, or the like; Figure 5 shews this chamber when under pressure; Figure 8
is a diagram of the capsule before being pressed; Figure 9 is a diagram of the same
after having been pressed in one of the aforesaid chambers; on relaxing the pressure
the bottle is slightly turned, and the capsule is then in the condition represented
in Figure 10; Figures 6 and 7 show soft india rubber chambers used for putting
on tin foil.
In Figures 11 and 12 one of my improved machines is shewn on a pedestal R, to
which it is attached at S; the head of the said machine is constructed as herein-
before described. This machine can also be worked by foot power instead of being
worked by the hand lever E.
Having thus fully described the said Invention, and the manner of performing
the same, I wish it understood that I claim,-
First. In a capsuling machine the method of forcing the plunger up by depressing
the lever or handle.
Second. In a capsuling machine an elastic chamber of semi hard india rubber
constructed as described and as represented in Figures 4 and 5 of the Drawings.
Third. The machine mounted on a pedestal, so that it can be placed in any
desired position and worked independently of a table or other similar support.
All substantially in the manner and for the purposes specified.
In witness whereof, I, the said Frank Wirth, have hereunto set my hand
and seal, this Tenth day of September, in the year of our Lord One thousand
eight hundred and seventy nine.
FRANK WIRTH. (L.S.)
