PROVISIONAL SPECIFICATION.
An Improved Machine for Moulding Suppositories, Bougies, Pills,
and the like.
I, HENRY POLLINGTON HEARDER, M.P.S., Chemist, of 26, Westwell Street,
Plymouth, Devon, do hereby declare the nature of this invention to be as
follows:-
-
This invention is an improved machine for moulding suppositories, pessiaries,
bougies, pills & the like.
This machine of brass or other metal consists of a circular barrel (Drawing No. 1
Figs. 1 & 2 A) to which a breach block (Drawing No. 1 Fig. 2 F) is fitted by a
bayonet catch. Through this breach block a screw piston rod (Drawing No. 1
Figs. 1 & 2 B) having a tightly fitting plunger (Drawing No. 1 Fig. 2E) fastened
at its end, works through the interior of the barrel.
The mould blocks (Drawing 1 Fig. 1 & 2 C [Drawg. 2, Fig. 3 C]) of such forms
shapes or sizes as may be required are then fitted by means of a screw, over the
mouth of the barrel.
A cap (Drawing 1 Fig. 1 & 2 D [Drawing No. 2 Fig. 3D]) is then fixed over
the mouth of the mould & leaves the machine in working order.
In using, detach mould block from barrel fill the barrel with substance to be
moulded, refix mould block & screw in the plunger by means of the handle
(Drawing No. 1 Fig. 1G) until moulds are filled by means of the holes
(Drawing No. 1 Fig. 2 H [Drawing 2 Fig. 3 H]) remove cap, give handle two
turns & the substance will be thrust out in the shape required.
For bougies, pessiaries pills & the like the substance is forced in like manner
through the hole (Drawing 2 Fig. 4 & 5 H) in the caps (Drawings 2 Fig. 4 & 5 D)
instead of into the moulds as in Drawing No. 1 Figs. 1 & 2 C.

[Price 8d.1

in and by the following statement: -
This invention is an improved machine for moulding suppositories, pessaries
bougies pills and the like.
This machine of brass or other metal consists of a circular barrel (Drawing No. 1
Figs. 1 & 2 A as filed with my Provisional Specification) to which a breach block
(Drawing No. 1 Fig. 2 F) is fitted by a bayonet catch.
Through this breach block a screw piston rod (Drawing No. 1. Figs. 1 & 2B)
having a tightly fitting plunger (Drawing No. 1 Fig. 2°E) fastened at its end,
works through the interior of the barrel.
The mould blocks ((Drawing No. 1 Fig. 1 & 2C) (Drawing 2 Fig. 3 C)) of such.
forms shapes or sizes as may be required are then fitted by means of a screw over
the mouth of the barrel and contains the cavities in which it is intended to form the
suppositories pessiaries and the like by extrusion.
These cavities are filled, through a series of small holes in the underside of the
mould block which lead into them, by screwing in the piston & forcing the sub-
stances the suppositories & the like are to be made of through these small holes
into the cavities of the mould. A cap is screwed or fixed with a bayonet catch or
clip over the top of the mould or mouths of these cavities in order to exercise
sufficient pressure on the substance used to make it fill them up, after which the
cap is to be removed to enable the formed suppositories.to be extruded from the
cavities of the mould block, in the shapes required by an extra two turns of
the handle.
In using, detach mould block from barrel fill the barrel with substance to be
moulded refix mould block and screw in the plunger by means of the handle
(Drawing No. 1 Fig. 1G) until moulds are filled by means of the holes ((Drawing
No. 1 Fig. 2 H) (Drawing 2 Fig. 3 H)) remove cap, give handle two turns and the
substance will be thrust out in the shape required.
For bougies pessaries pills and the like the substance is forced in like manner
through the hole (Drawing 2 Figs. 4 & 5 H) in the caps ((Drawing 2, Figs. 4 & 5 D)
instead of into the moulds as in Drawings No. 1, Figs. 1 and 2 C).
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 what
I claim is
1. Novelty of shape and construction which ensure rapidity of execution.
2. That it supplies a universal want which has always been felt and will be
invaluable in hot climates where the menstruum after being melted takes sometime
48 hours to set.
3. Novelty of the method, being compression and extrusion instead of fusion
and casting in moulds.
4. That there is nothing approaching it for convenience or portability.
