Improvements in Bottle Forming Machines.
I, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 :-
-
I will describe a bottle forming machine, embodying my invention and then point
out the novel features in claims.
In the accompanying drawing,
Figure 1 is a front view of a bottle forming machine embodying my invention.
Figure 2 is a side view thereof.
Figure 3 is a front view showing certain parts in a different position from that
shown in Figure 1:
Figure 4 is a side view thereof partly in section.
Figure 5 is an enlarged sectional detail showing a modification.
Figure 6 is an enlarged plan view of a certain part.
Figure 7 is an enlarged sectional detail of a certain part.
Figure 8 is a plan and elevation of formers employed.
Referring by letter to the drawing A designates a standard extending from a
suitable base A¹.
A shows a swinging standard pivotally connected at its lower end to bearings a
extended upwards from the base A.
The swinging standard A³ carries the two part mold A³. Each part of the
mold A' at its lower end has a hinge or pivotal connection with a stud a¹ on a plate
or platform a', here shown as adjustably connected, by means of screws a³, to a
plate a on the upper end of the swinging standard A'. By means of the screws a³,
the plate a' and the mold A' may be adjusted vertically.
Each part of the mold A' is connected by an adjustable link a with a lever A',
shown as pivoted at one end to an arm a on the plate or platform a². The
levers A, at the opposite end, are pivotally connected by means of a bar a', to the
upwardly extending arms as of a brace bar A'.
The brace bar A' at its lower end extends through a slot opening in a plate a³
extended from the base A', and the bar is notched at its lower end to form
shoulders a, adapted to rest on the upper surface of the plate a', to hold the mold
in operative position, as shown in Figures 3 and 4.
To prevent the standard A' from swinging too far forwards a stop bolt A' is
employed. This bolt has a pivotal connection with the standard A' and is extended
through a sleeve a" which is movable through a hole in the front wall of the
standard A. The sleeve a" has at each end an annular flange longer than the
opening through the standard and a spring a interposed between the end of
the sleeve a and a nut a¹³ on the stop belt A°, serves as a cushion to prevent jar
when the standard A' is moved to its forward position.
A' is a vertically movable rod provided with a plate or platform a" at its upper
end and having bearings in arms a projecting rearwards from the standard A.
These bearings are so arranged relatively to the standard A', that the rod A? will
assume a vertical position when the standard A' is in its forward position as shown
in Figure 2..
:
The lower end of the rod A' is connected by a link a" to a fulcrumed treadle A®,

page_text: which at its forward portion has a spring a" extended from it to the standard A',
which serves to return the rod A' to its downward position.
B is the former for the bottom of a bottle adapted to engage in and form the
bottom of the mold A³ and to have a slight vertical movement imparted to it by
the mold sections as they come together.
The bottom former B has on its lower side a stem b movable in a socket formed
in a lug on the plate or platform a². A bevel or cam surface 6 is formed on the
lower side of the bottom former adapted to engage with corresponding bevels or
cam surfaces b³ in the lower portions of the mold sections. Obviously, when the
mold sections are forced together the bevel or cam surfaces 62, 6, will force the
bottom former upwards and depress the bottom of the bulb of glass in the
mold.
I will now describe the means for carrying a bulb of glass to the mold and
expanding or blowing the same.
B¹ designates a carrier here shown in the form of a wheel mounted on a tubular
hub B', having a horizontal bearing B³ in the upper portion of the standard A.
A pipe B, provided with a valve connects with the tubular hub B' and serves
to convey air, under pressure, to the interior of the hub for the purpose of blowing
a bottle as will hereinafter appear.
C designates a tubular casing, the interior of which forms an air chamber having
communication with the tubular hub B³.
The casing C is arranged at right angles to the hub B*. It has at one end a cap
or stuffing box C', and at the other end a cap or stuffing box C³, which, as here
shown, has an annular groove ċ formed in it.
C' is a blow tube having bearings in the caps or stuffing boxes C₁ C³ and movable
longitudinally of the casing C. The blow tube has a stem portion el extended
through the stuffing box C and provided with a head c at its end. A spring c
surrounds the stem between the head c² and the cap or stuffing box C¹ and serves
to move the blow tube longitudinally to bring its end c wholly within the cap or
stuffing box C³.
The blow tube is intended to be forced into the glass forming the neck of a
bottle X and it is movable through a fixed sleeve the projecting end c' of which is
tapered to provide a former for the outwardly flaring mouth of the bottle.
The chamber in the casing C communicates with the interior of the tube C
through perforations co, below a stop collar or sleeve ce surrounding the tube Cat
one side of an annular shoulder c' formed in the interior of the casing C. This
shoulder and stop collar or sleeve prevents the spring from moving the tube too
far outwards.
D designates tongs or formers for the exterior of the mouth of a bottle. The
tongs or formers D are carried by the carrier B'. The former sections D have 4
interior heads d to fit in the annular groove c of the cap or stuffing box C. These
former sections D have a horizontal movement toward and from each other.
An arm D' extends rearwards from each tong or former section D and the arms
at the rear ends are pivoted on a bolt or stud d' on a bracket D2 secured to the
carrier B'. Each section of the former D is removably-secured to its arm D¹ by 4
means of a suitable thumb screw. The former sections are forced together by
means of springs d² bearing at one end against the arms D' and at the other end
against the former sections D, when desired, I employ a cam d³ engaging the inner
sides of forwardly projecting portions d' of the arms D¹. The cam consists of a
plate mounted on a shaft d, having a bearing in a plate d secured to the cap 5
piece C. A handle d' is provided for turning the cam plate.
The former sections D hold the glass in position, before the
around it, by means of inwardly projecting beads or shoulders
lower portion of the head of the bottle.
mold A' is placed
which forms the
E shows a holder or receiver for glass. It is made in two separable sections 5
adapted to fit closely together, similar to a mold A°. Each section is secured to

page_text: an arm e. The arms e are crossed and fulcrumed at their point of crossing to a
stud extended from the carrier B¹.
*Links e' are pivoted at one end to the ends of the crossed arms e ate, and at
the opposite end these links have a coincident pivotal connection with an operating
lever E'.
The lever E¹ has a pivotal connection e with the carrier B¹, and a yielding
friction plate e is affixed to the carrier B to engage with the lever E' and hold it
as adjusted.
the
Obviously, by moving the lever E¹ from one end to the other of the plate
links and arms may be operated to close or separate the parts of the holder E as
desired.
It will be observed that the arms, links and lever first described are in the rear
of the casing C, and that the ends of the arms e, connecting with the sections of the
holder E are extended forwards so as to bring the holder sections in line with the
casing C.
.
When the sections of the holder E are closed together they engage around a
portion of the tongs or formers D.
The carrier B is intended to be oscillated back and forth, a one half resolution,
and I therefore provide stops. These stops consist of a lug e extended rearwards
from the carrier, and lugs e extended from the standard A. When the lug e'
contacts with one of the lugs e, a further movement is prevented. Set screws e
may be provided on the lugs e, for the purpose of adjustment.
In Figure 5, I have shown a sleeve F, surrounding the blow tube and within
which the tube is movable longitudinally. This sleeve has at its end a former for
forming the mouth of a bottle. The sleeve has opposite slots F in its wall and a
pin extended through the blow tube projects into those slots. An annular
shoulder on the blow tube normally at some distance from the end of the sleeve
allows the end of the blow tube to be forced some distance into the mass of glass:
before the shoulder f' comes in contact with the end of the sleeve to force the end
of the sleeve into the mouth portion of the bottle. When the blow tube is allowed
to resume its normal position the pin f1 engaging with the end walls of the slots
will draw the mouth former out of the glass, into which a small amount of air is
admitted before the parts are reversed.
In operation the machine is placed in the position shown in Figures 1 and 2, with
the formers D closed and the receiver E also closed. After placing the glass in
the receiver E, the blow tube is forced upwards, by means of the treadle A³, the
rod A and the link a", to push the mouth former into the mass of glass, then the
rod A', is allowed to lower, and a small amount of air is admitted, then the carrier
is given a one-half rotation in the direction indicated by the arrow in Figure 1,
which will bring the parts thereon to a reverse position. Now the lever E' is
operated to separate the receiver sections as shown in Figure 3.
By drawing upwards on the bar a' standard A' is caused to assume a vertical
position and this motion causes the mold sections A³ to close around the glass.
The several parts of the machine will now be in position shown in Figures 3 and 4.
While the parts are in this position the valve is opened to allow a pressure of
air to enter and expand or blow the glass in the mold and form the bottle.
After forming the bottle the mold A³ is removed and also the formers D and
then the bottle is removed.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is:
