COMPLETE SPECIFICATION.
A Machine for Fashioning the Necks of Bottles and Forming
Recesses, Marks, and Raised Portions therein and thereon.
I LOUIS BOUNEU of 352 Avenue de Longchamps, Uccle near 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 :-
My invention consists in the machine hereinafter described for shaping or
fashioning the necks of bottles with the object of imparting to them a regular shape
as well as an internal diameter of invariably uniform dimensions which is important
for obtaining ready secure closure. The said machine is also serviceable for
producing beads or raised portions on the bottle-necks or recesses or marks
therein.
I will describe my said invention with reference to the accompanying drawings
as applied to a machine for shaping bottle-necks and forming thereon a bead or
band and two tenons or lugs.
Figure 1 of the said drawings is a side elevation of the machine with its parts
in the positions which they occupy while the bottle-neck to be shaped is being
inserted.
Figure 2 is a front elevation of the said machine.
Figures 3, 5 and 7 are side elevations showing the successive positions of the
acting parts during working of the machine and Figures 4, 6 and 8 are corresponding
front elevations.
Figure 9 represents a detail drawn to a larger scale than the other figures.
In the said figures A is the frame the front part of which is turned up at a right
angle and is provided with a large circular aperture in which a plate M revolves.
The rear part of the frame A is occupied by a bearing D supporting a shaft J on
the rear end of which are mounted fast and loose pulleys C and B driven by any
suitable motor. On the forward end of the shaft J the plate M is affixed and in
the said end of the said shalt a circular groove R is formed. The said shaft J is
hollow for part of its length from its forward end rearwards and along it is formed
a shallow groovej which communicates near the middle of the length of the said
shaft with a slot cut through the whole thickness of the wall of the hollow shaft
and forming a slide-way. Within the bore of the hollow shaft Jare inserted a
spindle projecting from the front of the plate M and a spiral spring i which
opposes inward motion of the spindle I within the shaft J. GG and H Ĥ are two
pairs of levers pivotted to supports m which project from the rear face of the
plate M and are integral therewith. The extremities of the rearward arms of
these levers which are furnished with anti-friction rollers are pressed against the
shaft J by springs m¹ secured to the supports m. The rearward arins of the
levers H H are considerably longer than those of the levers G G and the
extremities of the forward arms of the said levers pass through cruciform slots in
the plate M and project from the front of the said plate.
The projecting ends of the two levers GG carry rollers K K which are capable
of turning freely on the said ends and in the periphery of each roller is cut a
circular groove k which serves to form the bead or band around the bottle mouth.
The projecting ends of the two levers H H carry dies P P the faces of which are

page_text: curved to fit the bottle-neck which is fashioned by the rollers K K and in each of
the said curved faces are formed a groove p for reception of the band shaped by
the rollers and a small recess pl for reception of the glass which is to form the lugs
or ears upon the bottle-neck.
Upon the shaft J is loosely mounted a sleeve S which carries or has formed on
it a ring F in the periphery of which is formed a circular groove wherein are
engaged two studs T secured at opposite points within the branches of a fork N
which embraces the said ring F and the lower ends of which branches are pivotted
at O on each side of the frame A of the machine. A handle secured to the top
of the fork admits of the said fork being turned on its pivots so as to cause the
ring F and the parts on the shaft J which are engaged with it to advance or
recede.
On the front end of the sleeve S is formed a blocks having two truncated
parts connected by a cylindrical part.
The spindle I carries two stops which are engaged in the slot of the
shaft J. The front stop does not extend beyond the level of the bottom of the
groove but the rearward stop is somewhat longer. Through the block s is
screwed a threaded rod 8' the end of which travels in the groove of the shaft J
when the sleeve S is set in motion by the fork N. The end of this rod s¹ when the
sleeve slides towards the rear of the machine meets the stop and if the movement
of the sleeve continues it carries the said stop with it and causes the spindle I t
move inwards in the hollow of the shaft J compressing the spring i.
The spindle is perforated throughout its length to permit air to escape from
the bottle during the operation of the machine. In the portion of the spindle which
projects in front of the plate M when the spring i is extended a circular groove tis
formed the position of which relatively to the dies P P is such that the said groove t
is between the grooves p and the recesses p¹. From the groove t the diameter of
the spindle remains uniform for a short distance beyond which it gradually decreases
to its forward extremity.
The handle of the fork N may be connected to the driving belt in any suitable
manner so that when it is pulled back it may cause the said belt to shift from the
fast to the loose pulley and arrest the rotation of the shaft J and so that the said
belt may be brought back onto the fast pulley when the said handle is moved to its
forward position.
The machine acts as follows:-
Rotation being communicated to the shaft J and to the parts connected there-
with by the driving belt on the fast pulley C and the several parts occupying the
positions represented in Figures 1 and 2 the attendant after having placed a fillet
or ring of hot glass around the neck of the bottle and after having placed the said
bottle in a holder places the rod of the said holder upon a trestle situated in front
of the machine and pushes the said rod until the bottle neck into which the mandrel 1
enters is close to the groove R in the extremity of the shaft J. By the aid of the
handle of the lever N he then causes the sleeve S to recede until the ends of the
levers GG resting on the sleeve S after ascending the incline come to rest on
the cylindrical portion of the blocks as shown in Figure 3. By this movement
the levers G are caused to turn on the supports to which they are pivotted and the
shaping rollers K K (see Figure 4) are caused to move towards each other until
they come into contact with the outer surface of the neck of the bottle when
as the said levers turn freely on their axes they distribute the glass evenly or
equally around it forming the desired bend or mouth-ring by the action of their
grooves k. The pressure exercised by the rollers upon the bottle neck has also the
effect of forcing the glass into the groove t of the spindle I whereby a projecting
bead within the bottle neck is formed. The attendant next moves back the sleeve S
until the ends of the levers H H come in their turn to rest upon the rear edge of
the cylindrical portion of the blocks while the extremities of the levers G G
descend along the inclines and come to rest on the shaft J as illustrated in Figure 5.
By this backward movement of the sleeve S the screwed rod s¹ of the block s is

page_text: brought into contact with the top of the peg of the spindle I the shaping
rollers K K are caused to recede from the bottle neck and the driving belt is
caused to pass outo the loose pulley B. The shaft J and its connections and the
dies P P cease rotating and the said dies move towards each other until their edges
come into contact as illustrated in Figure 6. The external ring or bead formed
by the groove k of the rollers. G G then enters the groove p in the dies P P the
curved faces of which form a collar around the neck of the bottle.
The attendant then draws back the sleeve S at one stroke as far as it will go
that is to say until the rear peg or stop of the spindle I engaged with the screw
threaded rod of the block a abuts against the rear end of the slot in the shaft J
as shown in Figure 7.
The effect of this movement is to compress the spring i and to cause the spindle I
to retire into the hollow of the shaft J while the ends of the levers H H at first
slide along the cylindrical surface of the block keeping the dies P P closed
and afterwards descend the incline of the said block thereby opening or separating
the said dies P P and finally in their turn come to rest on the shaft J when the
dies P P are fully open as represented in Figure 8.
While the ends of the levers H H are sliding over the cylindrical surface the
spindle I re-enters the shaft J for a distance equal to the length of the said
surface and as the dies P P remain closed the while the glass which fills the
groovet of the spindle is forced out radially by the said spindle and supplies to the
bottle neck a supplementary quantity of glass which is forced into the recesses pl
of the dies P P and forms the external lugs on the neck.
The complete withdrawal of the spindle corresponds to the full opening of the
dies and as the rollers have separated already there is no obstacle to removal of the
finished bottle.
In order to prepare the machine to receive a fresh bottle for 'the next operation
the attendant advances the sleeve S until the several parts resume the respective
positions in which they are represented in Figure 1.
Instead of forming ou the necks of the bottle one bead or band and two luga it
will be readily understood that by the employment of fashioning rollers and dies of
appropriate form the shape of the bottle neck may be varied and variously formed.
and disposed grooves impressions and projections may be produced therein or
thereon.
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. A machine for fashioning the necks of bottles and forming therein or
thereon recesses or projections characterized by two pairs of levers the front ends
of which carry shaping rollers or dies and which are pivotted on a revolving shaft
against which rest their rearward ends which are of unequal length a sleeve
furnished with a block and mounted upon the said shaft a spindle situated in the
forward end of the shaft and protruding between the dies and rollers of the levers
and means for causing the said sleeve to slide upon its shaft so that its block
successively meets and raises the rearward ends of each pair of levers and thus
depresses towards the spindle the rollers or dies carried by the forward ends of the
said levers substantially as hereinbefore described and illustrated in the accom-
panying drawings.
Secondly. The arrangement for forming lugs or projections upon the necks of
bostles cousisting in connecting the spindle situated within the bore of the hollow
shaft to the block of the sleeve so that when the said sleeve recedes towards the
rear of the machine it causes the spindle to move inwards in the hollow shaft
compressing a spring in providing one pair of levers with dies in which are formed
recesses the counterparts of the projections to be formed on the bottle neck and in
forming a circular groove in the projecting end of the spindle for the purpose of
forming a bead or band of glass within the bottle neck the mass of which glass

page_text: will be forced into the recesses of the dies when the spindle is being drawn back
by the sleeve substantially as herein before described and illustrated in the accom-
panying drawings.
