PROVISIONAL SPECIFICATION.
Improvements in Cigar-bunching Machines.
I, MAX VAN GÜLPEN of Mulheim on the Rhine in the Kingdom of Prussia Cigar
Manufacturer do hereby declare the nature of this invention to be as follows:-
This invention relates to the part of a cigar bunching machine in which the
bunch is received and pressed after the rolling operation which may be performed
as described in the Specification to Letters Patent granted to me dated 12th Novem-
ber 1888 No. 16369.
According to my present invention a multiple mould is provided for the reception
of the bunches in place of the single mould described in my said former Specification.
This multiple mould or series of moulds which may be composed of separable parts
or otherwise is arranged to rotate or otherwise travel before the delivery end of the
bunching machine in such a manner as to present the moulds or cavities successively
and at the proper moment for the reception of the rolled bunches. For example the
moulds may be arranged on the circumference of a rotating cylinder built up with a
series of segments part of each of which forms a division between two adjacent
moulds. These segments are formed with suitable cavities or hollows on opposite
sides so that when placed side by side they form moulding cavities of suitable form
and are preferably moveable individually so as to enable the bunch to be easily
loosened in the mould for removal. With this object the segments may be pivoted at
both ends to a frame or disc or preferably they are secured at both ends but in such a
manner as to allow them to be moved on the axis of the cylinder and be tightened up
by a pivoted hinged or other wedging piece or the like bearing against a suitable
support or segment or projection fixed on the axis or by any other suitable mechanical
device.
To enable the moulds to be placed in succession in the proper position for receiving
the bunches suitable stops such as spring pins or catches engaging with holes or
notches in discs or the like attached to the axis of rotation are employed.
In place of being arranged on the periphery of a cylinder the moulds may be
carried in any other suitable manner being attached to a chain belt or apron working
on rollers for example or they may be arranged in a line or end to end and travel
laterally or transversely to the machine.
The bunches are pressed into the moulds by means of an improved arrangement of
levers acting on the cover of the mould which is attached to a hinged plate or arm so
as to be capable of being readily turned back or swung clear of the mould when
required.
As each bunch is deposited in its mould the cover is turned down on the bunch and
then the levers are brought down on to the cover so as to apply the desired pressure.
The cover is then turned back and the mould carrier rotated or moved sufficiently to
place an empty mould or cavity in position for receiving a bunch.
When all the moulds of the rotary cylindrical carrier are filled the wedge is
loosened and then each segment can be moved in succession so as to loosen the bunches
which can then be readily taken out of the moulds.
Dated this 3rd day of March 1800.

Improvements in Cigar-bunching Machines.
I, MAX VAN GÜLPEN, of Mülheim on the Rhine in the Kingdom of Prussia,
Cigar 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 :-
In the Specification of the cigar bunching machine for which I obtained Letters
Patent dated 12th November 1888, No. 16369, I have described a machine which
works with an apron attiched at both extremities to a table, and a moveable frame
carrying a roller by which the fillers being placed in the bight of the apron and
wrapped in the latter, are compressed with a rolling action into a bunch. This
bunch is enveloped in the binder and deposited by the apron in an open mould pro-
vided with a cover or hinged top-part, which compresses the bunch and imparts to
it the required form, the closed mould being afterwards removed from the machine
and taken to the operator who puts on the wrappers.
According to my present invention I employ in place of single moulds, as
described in my said former Specification, a number of connected moulds or a multiple
mould so arranged as to be capable of rotating or otherwise travelling with a
suitable step-by-step motion in front of the delivery end of the table of the machine,
so as to receive the bunches one after the other, thus obviating the inconvenience
attending the previous arrangement and arising from the necessity for removing each
mould separately and putting another into position whenever a bunch is delivered
from the table.
The said multiple mould is composed of sections forming together a series of divided
moulding-cavities and so connected side by side to a carrier that they may be shifted
in transverse direction relatively to each other. When these sections are pushed
close together and kept in this position, they are in the state for receiving the bunch
and allowing the same to be compressed therein by a cover or counter-mould-part,
whereas when they are spread apart or shifted away from each other, they release the
moulded bunch so that it may then easily be removed.
The carrier to which the sections are connected may consist in a double travelling-
chain running over two barrels, or in a sliding frame, or a rotating shaft. In the
first arrangement the sections are so fixed or connected to the links of the chain
as to be in contact with each other when the chain is stretched out in a straight
line, as is the case relatively to the parts of the chain being, during the motion
of the chain, between the two barrels, the sections under these conditions spread-
ing apart automatically as the chain passes upon either barrel. In view of securely
keeping the chain straight between the barrels it may be supported by guides.
If the carrier is to consist in a sliding frame or a shaft, one or more clamps or
key-pieces are provided for, whereby the sections can be kept close together or
released at will.
In the annexed drawings a multiple moulding apparatus of my invention is
represented in which the mould-sections are mounted on a shaft so as to form a
cylinder. Fig. 1 is an end-view showing the counter-mould-piece and certain levers
turned back. Fig. 2 is a plan corresponding to Fig. 1. Fig. 2ª is a sectional view
of a detent-mechanism. Fig. 3 shows the apparatus in end-view with the counter-
mould-piece turned down into the appermost cavity of the mould-cylinder and the said
levers in operating position. Fig. 4 is a transverse section and Fig. 5 a longitudinal
section of the mould-cylinder. Fig. 6 shows in end elevation and in top view the
counter-nould-piece with parts to which it is fixed.
The said mould-cylinder is composed of a plurality of sections f forming on each
side one half of a mould, and two sections fi f having the form of a mould-half
on one side only. These mould-sections are provided each with two eyes with
which they are strung on the shaft w, and they are arranged to have so much

page_text: play that when they are all pushed close together, a space will be left between two
of them, such as is shown in the drawing between the sections f¹ and f2. The
section is preferably fixed to the shaft. By these means all the sections, except the
section f¹, are rendered capable of being rocked on the shaft and of being shifted
laterally one after the other in view of spreading them apart and allowing the
bunches deposited in the moulds to be removed. For the purpose of maintaining
the sections fin contact with each other and with the sections f'f' during the opera-
tion of moulding, a wedge-like key-piece q is inserted into the space between the
sections ff. This key-piece is pivoted to the section fl and provided with an arm
whereby it may be turned up and down, as shown in Fig. 5.
The described mould-cylinder is placed with its shaft w in bearings formed in a
frame e, and which are so constructed as that the cylinder may be easily removed and
exchanged for another one. Opposite to the cylinder is pivoted to the frame e a
plate carrying the counter-mould-piece t in such position that when the plate is
swung towards the cylinder, the piece t will engage with the uppermost moulding-
cavity thereof (see Fig. 3), while on the other side of the cylinder are mounted on a
shaft g two lever-arms provided with handles and adapted to be turned down on the
bar fixed to the plate t¹, this arrangement affording convenient means for pressing
the piece t down upon the bunch present in the said moulding-cavity.
be
In order that previous to each moulding operation the moulding-cylinder may
arrested in such position that one of its cavities is in the path of the counter-piece t
when being swung over, a detent-mechanism is provided for. This mechanism as
shown by the drawing consists in a disk p secured to the sector f', and a conically-
pointed retaining-pin pl guided in a sleeve p² and impelled by means of a spring p³
against the disk p, which is furnished with holes for the pin to engage in, the said
holes being so arranged that every time the pin is in engagement with one of them,
the corresponding moulding-cavity will be in the proper position for receiving a
bunch as well as the counter-mould-piece f', and the cavity will be kept in this
position until the requisite rotative force is applied to the cylinder to cause the pin p¹
to be pushed back.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. For use in a cigar-bunching machine, a multiple bunching-mould composed of
sections forming together a series of divided moulding cavities, a carrier to which the
said sections are connected so as to be capable of transverse motion relatively to each
other, and means for keeping the contiguous sections in contact with each other and
for allowing them to be spread apart, in combination with a movable counter-
mould-piece fitting into the moulding-cavities, and means for guiding the said piece,
substantially as described.
2. For use in a cigar-bunching machine a multiple bunching mould composed of
the sections fff2 forming together a series of divided moulding-cavities, a shaft w
carrying the said sections, the sections fand f² having eyes with which they are
strung on the said shaft, and the key-piece q pivoted to one of the sections f¹ and
adapted to be inserted between the said sections f₁f2, in combination with a counter-
mould-piece t fitting into the moulding-cavities, and means whereby the said piece t
is guided to engage with the cavity brought into the path of the same, substantially
as specified.
3. The combination, with the multiple bunching mould defined in claim 1, of a
detent-mechanism whereby the bunching-mould is arrested whenever one of the
moulding cavities has been brought into the path of the counter-mould-piece, substan-
tially as set forth.
