SAMUEL WASHINGTON Managing Director Oaklands Harpurhey Manchester do
hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of Glass Bottles. The object of the
invention is to make at one operation a bottle having a finished or semi-finished lip
or flange. By this invention the mould in which the bottles are formed is made
with a loose neck or collar adapted to slide upon the neck of the mould. The said
moveable collar being supported by springs in such manner as to leave a groove
or cavity at the neck of the mould into which the glass is forced in the operation of
blowing. The said moveable collar being forced downwards whilst the glass is still.
pliable and thus pressing the glass which has been forced into the cavity into a solid
lip or flange of any desired shape or thickness.

Improvements in the Manufacture of Glass Bottles and Moulds
for the same.
I SAMUEL WASHINGTON of "Oaklands" Harpurhey Manchester Managing Director
of the James B. Hengler Manufacturing Company, Limited, 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 Invention relates to the manufacture of glass bottles, jars and similar vessels.
The object of the invention is to make at one operation a bottle having a finished
or semi-finished lip or flange. By this invention the mould in which the bottles
are formed is made with a loose neck or collar adapted to slide upon the neck of
the mould. The said moveable collar being supported by springs in such manner
as to leave a groove or cavity at the neck of tho mould into which the glass is
forced in the operation of blowing. The said moveable collar being forced down-
wards whilst the glass is still pliable and thus pressing the glass which has been
forced into the cavity into a solid lip or flange of any desired shape or thickness.
To clearly explain my invention reference is made to the accompanying drawings
in which Fig. 1 is a sectional elevation of an ordinary bottle mould having my
improvements applied thereto. Fig. 2 is a plan view of same and Fig. 3 is a view
looking at one face of the divided mould in the direction shown by the arrow
Fig. 1.
The mould a is formed as usual in sections which are suitably hinged together and
has the customary plug or "kick up" b therein. c and c are two arms attached to
or forming part of the mould. The part c may be attached to the bed plate d by a
thumb screw e as shown.
Around each section of the neck f of the mould I place a corresponding collar.
section g which is held up to same by a rod h the head of which is capable of
sliding in an opening in said collar. This rod has a boss i thereon having holes
for receiving
a tool for the purpose of turning same and terminates in a screw
thread ; which engages in a screwed socket k carried by an arm which is pivotted
at the point to a short standard secured to the part c (or c¹).
By turning the boss the thread j is screwed in and out of the socket k so that
the collar section 9 through the rod h may be kept up to the neck of the mould.
D. All

page_text: Each collar section ý has secured thereto or forming part of it a plate m having
a tapered or knife edge over-lapping the top of the mould neck. Said collar sections
and plates are adapted to rise and fall upon pins n secured to the parts c and c'. By
means of spiral springs o which surround posts screwed into the arms c c¹ and
which pass through the arms of the sockets A, the collar g is held up so that a groove
or cavity is formed between the underside of plate m and the top of the mould
neck..
The normal size of this space is adjusted by the thumb screw p and other nuts which
regulate the pressure of the arm of socket on the spring o.
Secured in the bed plate d is a post carrying a spiral spring which serves to
support a foot plate pivotted on standards secured to the bed plate. This foot plate
carries on the side bars of same and pivotted on short pins s, hanging blocks t which
when the foot plate » is forced down are adapted to press upon the collar sections.
The operation of the device is as follows:
The mould being placed over a pit in the usual way, the blower takes the necessary
amount of molten glass upon the end of his tube and after blowing it out into a small
bulb opens the mould as indicated by dotted lines in Fig. 1 inserts the mass therein,
closes it, and blows, the result being that the molten glass takes the shape of the mould
and is also forced into the groove or cavity between the plate m and the top of the
mould neck, the glass being blown hollow therein or in the shape of a fold. This
done the blower presses with his foot upon the plate which through the blocks t
forces down the collar upon the mould neck the plate m thus compressing the glass in
the cavity into a solid lip or flange, the knife edge on said plate m being sufficient
when the blow pipe is lifted to cause the frosting to break off close to the lip and to
leave the finished bottle in the mould or to only cling to it with sufficient force to
enable the bottle to be lifted from the mould and removed to the annealing furnace.
The edge of the plate m may have a knife edge or finely serrated' teeth as shown in
the plan view Fig. 2. If necessary the inside edge of the flange may be ground so as
to remove the slight roughness left by breaking off the frosting.
Although I have shown means for supporting the collar g and for forcing same down
so as to compress or form a solid flange on the bottle I do not confine myself to the
construction of parts shown as it is evident that the collar may be fixed and the mould
moveable.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1st. The improvement in the manufacture of glass bottles which consists in forming
and compressing a flange or lip thereon as the bottle is being blown in the mould
substantially as described.
2nd. A mould for the manufacture of glass bottles having a collar adapted to slide
upon its neck, and to compress a solid flange or lip upon the bottle substantially as
described.
3rd. The combination with the neck of a mould for forming glass bottles of a ring
or collar adapted to form a recess and to compress a flange or lip on the bottle
substantially as set forth.
