The submersible body 2 is given ascending and
descending movements by means of the rod Ill
operating at the same time the ‘articulated levers 40
9. The level of the water containing the paper
pulp in suspension being constant, it is easy to
see that when the body 2 is immersed, the level
rises in the trough I and the liquid is thus de
livered into the funnels 4, which are thus illled
exactly to the required extent.

At each reciprocation the body 2 in rising pro
duces the opening of the feed valve for the liquid
in the feed reservoir, in such a way as to re

female moulds i2 (formed of perforated metal or
other foraminous material) is effected. The
moulds l2 are ?xed to arms i3 of double cross
members l4 constituting a rotary carrier having
two ‘rows of moulds as shown in Fig. 2. In order
to permit the rotation of the carrier after each
?lling of the moulds, these funnels II’ are mov
ably mounted on levers l5 pivoted on a spindle
l6 and controlled by an articulated rod l1 con
ejection of the pieces by an admission of com
pressed air in the pipe 241 and they fall on a
travelling band 36. The receptacles thus sep
arated are then carried on by this hand through
the drier.
'
This travelling band 36 is operated at regular
intervals in synchronism with the different op
erations .which succeed ‘one another on the re
volving carrier. For this purpose the invention
provides a wheel 31 with four teeth and a ratchet 10
a lever l8 pivoting around a ?xed spindle l9 " 38, the assembly being operated by means of a
and provided with-a roller 2| on which acam rod 33 and cranks 40 and 4|. Moreover, a rod
10 nected to the rod I0. ' The rod I1 is operated by
20 driven by the motor of the machine acts.
It follows that at every rotation through 90° of
15 the carrier the submersible body 2 is immersed in
the liquid of the trough I and the funnels II are
slightly raised to permit the successive rotation
.of the said rotary carrier. around a new angle
of 90°.
20
The moulds l2 are positioned within cavities
22 formed at the extremity of each arm l3 of
the rotary carrier.’ In practice these moulds are
destined for the manufacture of receptacles
adapted to contain food or other products. It
25 should be understood that these moulds are re
movable and‘ may be replaced by others of suit
able forms and corresponding to those used‘for
the manufacture of similar articles. Each cavity
22 is provided with a perforated axially extending
30 channel 23 adapted to communicate with bores
24, 241 formed in'a central ?xed shaft 25 on which
the rotary carrierlturns. Four longitudinal bores
24 or 241 may be provided in shaft 25, ?exible
tubes 26 connecting with said bores opening at
35 the side (Fig. 2) and in communication either
with a suction device (not shown) destined, as
will be seen in the following, to produce in the

of a ratchet wheel 43, a lever 44 and a ratchet
pawl 45, the whole assembly of the rotary car

rier step by step.
It has been found that‘the operation of the re
volving machine permits moulded receptacles to
be made at the rate of 5,000 to 6,000 per hour
according to the number of arms on the shaft 25. 20
when the primary material has been injected
into the moulds l2 (position A) the removal of
the excess water is effected through the bores 23
and 24. This operation may, by a suitable for
mation of- the ends'of the passages 23 and 24, be 25
continued during the whole of the time of the
revolution of the carrier through an angle of 90°
‘and until the moulds containing the moulded ob
jects are placed in the horizontal position B
which corresponds to that of separation from the 30
mould. At this instant, the bore 241 is connected
to an air compressor and the male moulds 30 are
introduced into the moulded objects. Com
pressed air'separates these objects and the latter
are at thez same time subjected to suction by the 35
air traversing the pistons 21 through the perfora
tions 34; the objects are thus automatically sep- '
?rst place in the position designated by the let
arated from the moulds. The pistons 21 are then

of the mould l2, or with an air compressor for
producing the separation of the manufactured
objects from the moulds (position shown by the
letter B) and their expulsion from the moulds
(position C) in order to permit their ?nal drying.
The position D corresponds to vthe cleaning of the
moulds.
The separating device comprises pistons 21
guided by supports 28 and of. which the heads 29
carry perforated male mould elements 30 of which
the external dimensions correspond exactly to the

bring the separated‘objects above the .travelling
band (position C) on which they fall successively,
due to the rotation of the machine.
In the position D of the carrier, the moulds l2
are subjected to a cleaning by water in order to 46
ensure perfect continuation of the operation. To
this end the invention provides closing devices
451 mounted on guides 43 and connected by ?ex
ible conduits 41 to a reservoir of water under
pressure. A rod 48 connected to a lever 43 piv 50
oting around a spindle 50 actuates these closing
internal dimensions of the objects which are to be devices 451 with rectilinear alternating move

The machine described permits two objects

to be made at the same time, but it is well un
similarly to the female moulds l2.
At this moment there is produced through an derstood that it could be applied to the manu
facture of a greater number of objects by increas
65 axial perforation 34 in each piston an air suction
. by means of a ?exible pipe 35 which separates the
pots or moulded objects from the moulds l2 by
suction, and this operation is facilitated by pres
sure air which is introduced by the bores 241
70 opening at the end ofthe cavities 22. There
upon, by an admission of compressed air into the
piston 21 by a pipe 351 the moulded pieces' are
forced back to the interior of the moulds l2 to
which they then only lightly adhere. A further
75 revolution of 90° permits, in the position C, the
ing its width.
It should be noted vthat, in order to obtain a
good separation from the moulds, the moulded
objects should be made slightly conical. During
the moulding of bottles, the cap could be molded
at the same time-as the body and the ?lling could -70
be effected by the circular lower part at the base
of the bottle. The bottom thereof would then
be constituted by a metallic'closlng ring destined
to close the container completely.
