I, Theodor KupPER, of Styrum, Rhenish Prussia in the German Empire, Iron
turner, do hereby declare the nature of my invention and in what manner the'
same is to be performed to be particularly described and ascertained in and by the
following statement:―
Tue invention forming the object of the present application for Letters Patent
and illustrated in the accompanying drawings, consists of a machine for the blow-
ing of hollow glass cylinders.
This apparatus has been devised in order to provide a means for the manufacture
of glass cylinders by purely mechanical means replacing the operations hitherto
performed by the glass blower by means of the glass blowing pipe and swinging
and blowing, further, it has for its object to render possible the manufacture of
larger pieces of glass than hitherto practicable by hand.
Referring to the accompanying four sheets of drawings:
The Machine is illustrated in Sheets 1 and 2, in longitudinal section in Figure 1,
in side view in Figure 2 and in plan in Figure 3, whilst Figures 4 to 8 illustrate
details on a larger scale.
Sheets 3 and 4 show a modified construction;
In these, Figure 9 illustrates a longitudinal section, Figure 10 a plan and.
Figures 11 to 18 details of the machine.
The apparatus consists essentially of a projecting piece C E adjustable in height
upon a perpendicular column A B, and in which a hollow shaft G forming the
conductor of the compressed air is revolubly situated. The said hollow shaft is
constructed at its front end in the form of a crank T in which a holding device S
revoluble upon a pin H is arranged for the blow pipe R. By the special means
provided this pipe can be moved not only in any desired direction but also be
revolved upon itself and during the revolution receive continuously the compressed
air. By this means all the conditions for the preparation of the glass cylinder are
fulfilled.
The projecting piece which can be revolved together with the tube B around the
column A is suitably arranged to be adjustable in height upon the tube B. This
is best effected by means of the mechanisms shown in the drawing, namely by
crank and tooth wheel gearing, whilst the counter weight D holds the projecting
piece balanced in every position.
The projecting piece combined with the sliding piece C consists of the tube E
The hollow shaft G
which latter bears the hollow shaft G in the bearings c c.
is prolonged into a crank T and possesses at its end the hand wheel F which serves
for the swinging of the glass cylinder hanging from the end of the pipe R held by
mechanism.
"
The holding mechanism illustrated on a larger scale in Figures 6, 7, and 8
consists of two clips' S fixed upon the screw spindle P which clips can be approached
te or withdrawn from one another by turning the wheel O and which serve to hold

page_text: the low pipe R. This latter possess a box y, which is fixed revolubly upon the blow
pipe by means of two rings and u.
Consequently the blow pipe R together
with the glass cylinder attached to it can move as follows:-
1. On its own axis.
2. Together with the clip upon the bolt H..
3. With the projecting piece around the axis of the tube B.
4. Together with the same up and down vertically.
In order to keep the blow pipe supplied during all these motions continuously
with the requisite compressed air the following arrangement has been devised: -
The compressed air conductor K controlled by valves or the like terminates in the
columi A, into which passes through an air tight stuffing box the tube Y con-
nected to the hollow shaft E. The air tight connection between the hollow shaft E
and the clip S is effected by means of an indiarubber tube fixed upon the projecting
pieces IH respectively so that the movement of the same around the bolt I can
take place unhindered. The tube is terminated by a cone k inserted air tight in
ne stuffing box q. From this latter the compressed air passes through several
holes into the pipe R.
t
The operation of the apparatus is as follows:-
The glass blower takes the necessary quantity of glass upon the tube in the
well-known manner and places this, together with the box 7 for the purpose of the
so-called preliminary shaping and ball blowing in a holder (Figures 15 to 18)
which also receives a supply of compressed aid, which as described passes into the
blow pipe through the stuffing box q When the ball is blown the glass blower
fixes the blow pipe with the stuffing box in the open clip S, closes the same by
turning the wheel and brings the blow pipe, together with the glass ball into the
horizontal position in which it is held fast by a coupling W with the aid of the
counter weight V. This is done in order that the considerably cooled glass ball may
be brought by the revolving projecting piece upon the column A into the heating
furnace and that the same may be there heated equably by means of the continuous
turning of the blow pipe. After the same has been sufficiently heated the pro-
jecting piece is turned back and the holding device released whereupon the glass
mass swings downwards into the swinging channel by its own weight and here
receives with continuous supply of air its cylindrical shape. In this manner the
heating and swinging of the glass is repeated until the cylinder is completely
formed.
In the modification illustrated in sheets 3 and 4 all hand labour for the actuating
of the separate mechanisms is completely obviated. In this construction gear
: wheels are employed; the gear wheel 1 upon the column A is utilised as a driving
wheel in such inanner that upon the turning of the swinging machine upon the
fixed pillar A the gear wheel 2 upon the pillar B with which latter a two armed
lever a for the holding of the pillars tt is connected, is revoluble around its axis x.
Upon each of these pillars there is placed an easily movable pulley upon which a
chain m'effects the transmission of the rotation of the tooth wheel 2 in combination
with the pillars t t to the tooth wheel 3 by means of the chain roller 6 placed upon
the said wheel 3 and revolving upon the same axis. The wheel 3 with the chain roller
is so arranged that it is supported by means of a lever f at a point which at its
lower limb bears the tooth wheel 3 with the chain roller whilst at its upper limb
there is arranged a slot in which a pin g is so arranged in connection with the
piece W, that the upper limb of the said lever f shares the in or out motion of the
piece W. By means of this arrangement the wheel 3 connected to the lower limb
of the lever f is brought into connection with the wheel 4 or released therefrom.
Consequently when the wheel 3 is in gear and its motion is transmitted to 'the
wheel 4, from this wheel to the following wheels 5, 6, 7, and from the latter to the
clip device S, then the parallel direction of the glass piece on the blow pipe will
remain corresponding to the opening of the heating device. The disconnection of
the wheel 3 has for its object when the coupling is moved out not to hinder in any
way the swinging of the glass piece with the clip; on the other hand however by
101

page_text: means of the arrangement that he coupling is drawn out for the swinging, but
at the same time engaged in the wheel 4, (to which also the claws of the coupling
are attached,) the tooth wheel 4 is fixed, and thereby the other gearing of the
clip and this apparatus itself are placed in a fixed position, where by any striking
of the glass against the walls of the swinging channel is avoided.
In order to render the rotary motion of the glass more easy for the glass blower,
there is placed between the clips and the crank a crown wheel d, which at its
outer periphery is provided with worm gearing and is revolved upon its axis by.
means of the worm e with the crank. In this wheel there engages a cone wheel S
placed upon the blow pipe R, so that upon the revolution of the said wheel with
the crank or worm the glass attached to the blow pipe will participate in the rotary
motion. Further, there is also provided the arrangement that a more rapid attach-
ment or removal of the glass from the blow pipe is rendered possible by providing
one of the clips S with an excentric, which effects the purpose that by a half turn
of the excentric by means of the crank W the two clips S may be sufficiently
approached to or removed from one another, and only a small portion of the worm
is requisite in order to effect a firm grip of the clips S.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A machine for the manufacture of glass cylinders hanging free from the
blow pipe by the swinging of the same under continuous supply of compressed air
Earacterised by a horizontal projecting piece adjustable vertically upon a per-
rendicular column, which projecting piece contains a crank shaft in which is
placed the conducting pipe for the compressed air, and which possesses a clip for
the blow pipe arranged in such a manner that this latter is placed in connection
with the compressed air tube by placing it in position, and is capable of rotation
upon its own axis, and also can be set together with the crank shaft in swinging
motion.
2. In the apparatus set forth in Claim 1 the adjusting device by means of which
the air inlet, the holding and turning mechanisms are controlled by means of
hand levers and gearing, substantially as herein described.
