Improvements in the Manufacture of Hollow Castings of Glass and
the like, and Apparatus therefor.
I, PIERRE DELORME Fils of No. 85 Rue Charlot Paris in the Republic of
France 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 relates to a moulding machine devised to produce articles of glass,
crystal and the like in which holes and cavities of various forms are require to be
made.
In order more fully to explain my invention I have designed and represented
in the accompanying drawings apparatus for producing at a single operation
and without need of further alteration heads of soda water syphons or of aerated
water containers.
In these drawings
:-
Figures 1, 2, 3, represent in section various syphon heals produced by the
moulding machines represented and described.
Figure 4 shows a transverse section of a moulding machine for producing the
head represented in Figure 1.
Figure 5 is a section on the line -x of Figure 4.
Figure 6 shows a detail of the mould for producing Figure 2.
Figure 7 shows a detail of the mould producing the apparatus shown in
Figure 3.
Referring to these illustrations, A. indicates the frame forming the base plate
upon which is mounted the moulding apparatus proper, formed of two half moulds;
the one D is fixed and provided with a slide C which connects it to the other
movable half mould E. Bolts d effect the closing and the combining of the half
moulds D E by means of a lever d¹. Below the frame A there is fixed a shaft B
oscillating by means of a lever C, the stops of which ab limit its course.
Upon the shaft B (Figure 4) are mounted cams the first one F controls the
lever whose oscillation is effected by means of the lever C¹, and which produces
the retreat of the piece f¹ whose head f' is designed to produce the cavity f³ of
Figure 1. The cams G H control in like manner the levers gh actuating the
pieces gto which the beads o² ² form the holes and cavities o³ ³ of Figure 1.
When the moulding pieces or cores are placed in the closed position the outer
moulds DE are bolted together and the glass or the like is run in through the
hole L. The molten material then fills the spaces left within the mould and when
the same has cooled the pieces f g h² are caused to withdraw by causing the
shaft A to oscillate. After this is accomplished the outer moulds are unlocked,
E is opened and the moulded piece is withdrawn and there is removed from it the
pouring piece corresponding to M and the projecting piece corresponding to m.
By means of the apparatus shown in Figures 5 and 6 the pieces shown in
Figures 2 and 3 are formed of different shape but their production is effected in
the same manner. In Figure 6 the cam is done away with and the lever f actuates
a circular piece f* devised to produce the hole f' shown in Figure 2.
In Figure 7 a single movable core g* is preserved and is destined to produce the
cavity of Figure 3. The hole g of the same figure is obtained by means of a
pin h which is preferably inserted by hand on account of its small dimensions and

page_text: its rapid heating. Nevertheless it is obvious that this pin might be arranged to be
operated automatically in the same manner as the other core pieces. The
production of these articles of glass or the like with holes or cavities is obtained as
may be seen directly without any intervention of delicate handwork, consequently
the pieces obtained are all alike and may be produced in any desired number.
In these pieces whatsoever forms, dimensions, and arrangements of the holes and
cavities may be required, they can be produced by varying the shape of the core
pieces or their direction or course accordingly.
· 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 :-
1. In a moulding apparatus with mobile cores an oscillating shaft provided with
the requisite number of excentrics or of cams actuating the levers controlling the
said cores substantially as described.
2. In a moulding apparatus with mobile cores the actuation of the said cores or
pins by levers sliding in slides arranged in the outer pieces of the mould or of its
frame and adapted to the shape of the cavity to be produced in the moulded
article substantially as described.
3. In a moulding apparatus with mobile cores the mould formed of one or more
pieces having a hollow of the shape of the outside of the object to be produced,
the said pieces of the mould being connected together by bolts, keys, sliding bars
or the like substantially as described.
4. The improved apparatus for moulding hollow articles of glass or the like
substantially as described and shown in the accompanying drawings.
5. The manufacture of moulded articles of glass or the like having internal
cavities and of regular shape such as the heads of mineral water syphons or the
like, substantially as described with reference to the accompanying drawings.
