COMPLETE SPECIFICATION.
Improvements in Machines for Shaping the Necks of Bottles, and
Forming therein Cavities or Recesses or Marks.
I LOUIS BOUNEU of No. 45 Rue d'Artois Brussels in the Kingdom of Belgium
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 :-
This application has for its object tresh improvements in the machine described
in the Specification of my Letters Patent No. 24589 dated the 3rd day of
November 1896.
These improvements have for their object to dispense with the use of a motor to
provide a machine capable of being operated by a single attendant and the parts
of which coming into contact with the glass have less rigidity.
I will describe these improvements with reference to the accompanying drawings
in which the same letters of reference indicate corresponding parts.
Figures 1 and 2 represent respectively in side and in front elevation, a machine
to which the present improvements are applied the parts being shown in the
positions they assume when the rollers are pressed against the neck of the bottle in
the course of action of the machine.
Figures 3 and 4 are corresponding views showing the parts in the positions they
occupy in the course of the operation when the shaping rollers are a slight distance
from the bottle neck and the dies are ready to be pressed therein in order to form
recesses or cavities.
The driving shaft is replaced by a very quick threaded screw J the rear end of
which is mounted in suitable bearings at the back of the frame and the front end
of which is fixed to a forked frame V the two arms or branches of which are
fixed to a circular carrier M turning in the circular opening in the front of the
frame A.
Upon the screw threaded shaft J is mounted a cam S having a central screw
threaded opening so that when the said cam is moved forward or backward upon
the said screw threaded shaft it imparts a rotary motion thereto.
The forward and backward movements of the cam S are communicated thereto
by the double operating lever N the arms of which work on the pivot o at the
lower part of the frame A. In the lever arms N at the height of the cam S
slots are formed in which are engaged pins s fixed to the cam S so that the
latter is moved forward or backward by oscillating or vibrating motion of the
lever. The cam S is in part of cylindrical form the remainder which is the forward
part being of the general figure of an annularly corrugated cone.
The cam
represented in the drawings has a depression at sa protuberance at 3 another
depression at s¹ and another protuberance at s.
The levers G carrying the shaping rollers K turn on supports m secured to or
cast in one with the carrier M and their free ends which are furnished with
antifriction rollers are pressed against the cam S by springs m¹ secured to the
carrier M consequently when the cam S is moved back until the free ends of the
levers G rest as shown in Figure 3 in the first depression or grooves the shaping
rollers K which were in their nearest positions to each other while the free ends of
the levers G rested upon the cylindrical portion of the cam will be slightly

page_text: separated and if the rearward motion of the cam S continues the rollers K will
again approach each other when the free ends of the levers G pass over the
protuberance and they will be further separated when the said free ends of the
levers G bear upon the bottom of the deepest depressions. When the cam is
moved to the end of its stroke the rollers K will once more move slightly towards
each other while the ends of the levers G are passing over the protuberances and
when the said ends rest on the screw threaded shaft J the rollers K will be at their
greatest distance apart.
When the cam S is moved toward the front of the machine the same successive
movements of the rollers K toward and from each other will be again produced in
the reverse order until they are brought into their nearest positions by the passage
of the free ends of the levers G onto the cylindrical part of the cam S.
The front ends of the levers G are engaged in radial grooves of the carrier M
and they are connected to the rollers K by spring attachments 9 which give
flexibility to the pressure of the rollers against the bottle neck. The central
spindle I is fixed in the centre of the carrier M and in a plate R which surrounds
it is formed the circular groove in which the bottle neck to be shaped is pressed.
The levers H which carry the dies P turn on the supports m2 projecting from
the rear face of the carrier M and their arms which carry the dies pass through
radial slots in the said carrier and are connected to the outer ends of the said slots
by springs p which tend to keep the dies away from the bottle neck.
The rear ends of the levers H are connected together by rods h which are jointed
to the ends of a small lever X mounted upon a small axis v fixed to the arms of the
fork V. The lever X is furnished with a handle by means of which it can be
turned on the axis v.
By reference to Figure 3 it will be readily understood that on depression of the
handle towards the front of the machine, the lever X will turn on the axis vand
cause the levers H to turn upon their supports m³ so as to bring the dies P towards
the neck of the bottle.
The machine acts as follows:-The attendant moves back the cam S by means
of the lever N until the free ends of the levers G G carrying the rollers bear upon
the screw threaded shaft J whereby the greatest separation of the shaping
rollers KK will be produced. After having placed a strip of hot glass around
the mouth of the bottle and placed the latter in a holder the attendant rests the rod
or handle of the latter on a support placed in front of the machine and pushes it
until the month of the bottle into which the spindle I enters is close to the circular
groove of the plate R. With the aid of the lever N he then brings forward the
cam S which in advancing imparts rotary motion to the screw threaded shaft J the
carrier M and the rollers K K the latter being successively caused to advance
toward and separate from each other according as the free ends of the levers G
pass over the protuberances ³ or into the depressions the said rollers being
in their closest position when the said ends ascend the cylindrical part of the
cam S.
When the rollers K approach each other they bear upon the outer surface of
the bottle neck and while turning freely on their axes they distribute the glass
evenly around the neck while imparting thereto a shape which is the counterpart
of that of the rollers.
After having repeated the alternative motion of the lever N two or three times
according to requirements the attendant stops the cam in the position corresponding
to the closest position of the rollers and rapidly shifts the handle x of the lever ✗
first towards the front of the machine and then backward again which brings the
dies P towards each other rapidly the said dies entering the walls of the mouth of
the bottle and forming recesses or cavities therein.
As soon as the dies have been withdrawn from the recesses formned by them the
attendant brings the cam back for the last time until the free ends of the levers G
bear again on the screw threaded shaft J. By this last operation the shaping
rollers are caused to complete the formation of the mouth by removing the

page_text: imperfections which may have been caused by the working of the dies and the
bottle may now be withdrawn from the machine.
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 I
claim :-
First. The screw threaded shaft or spindle having mounted on it a cylindrical
cam terminated by a corrugated reduced part so that to and fro motions
communicated to the said cam cause rotation of the screw threaded shaft.
Secondly. The levers turning upon supports fixed to the rotatory carrier to one
end of which levers the shaping rollers are connected by spring attachments while
their other ends are pressed by springs against the cylindrical cam terminated by
a corrugated reduced part.
Thirdly. The actuating mechanism of the dies the advance and retirement of
which are produced by a system of levers arranged in a frame fixed to the screw
threaded shaft and to the rear face of the rotating carrier.
Dated this Third day of March 1897.
