3 – 1828 – La maschera costruita da Lemaire D’Augerville
a completamento del suo ARA. Il corpo, sagomato, era in
rame e copriva anche il naso, era dotata di due vetri ed
elastici per il fissaggio alla testa. La tenuta era garantita
da una specie di mastice posto sul bordo. Alla maschera
era collegato uno dei due tubi di alimentazione per la respirazione
nasale. (da “HDS NOTIZIE” n° 8, 1998)
3 – 1828 – The mask built by Lemaire D’Augerville in completion
to his ARA. The shaped body was in copper to
cover the nose as well and it was provided with two glasses
and rubber bands for the holding to the head. The air
tightness was guaranteed by a kind of mastic placed on the
edges. One of the two feeding pipes for nose breathing
was connected to the mask. (From HDS NEWS n. 8, 1998).
(fig.3). Alla maschera è collegato un tubo proveniente
dal sacco per la respirazione nasale, dotato
anche di valvola di scarico. Un secondo tubo,
sempre proveniente dal sacco, permette la respirazione
orale. L’attrezzatura di Lemaire
D’Augerville, compreso la maschera, scompare
poi senza trovare quell’ampio consenso che
avrebbe meritato. La scarsa disponibilità d’aria
e privo delle fatidiche pinne, il palombaro ha
un’operatività limitata e l’avvento in quel periodo
dello scafandro da palombaro, che non pone
problemi di autonomia d’aria, ne ha senz’altro
facilitato la scomparsa.

1860-65 – Benoit Rouquayrol and Auguste
Denayrouze
Benoit Rouquayrol is a young mine engineers
very sensitive to the human problems of people
exposed to the hard work of the carbon mines
and to the danger coming from the presence of
the methane gas CH4 bags. These problems
reflect on the rescuers as well in case of accident,
as they are not provided with adequate and
effective protection equipment. He then dedicates
himself into finding a solution to this problem
and in 1860 he invents and patents a ”regulator
for the flux of compressed gases” to be
used both in toxic and underwater environments.
The air arrives through a hose to a horizontal
tank placed on the back of the person. On the top
of this is placed the ”regulator” that is a real and
proper single stage regulator.
In 1863 he invents and patents a new balancing
pump for air as well, with fixed pistons and
moving cylinders, constantly covered with a jet
of water to avoid overheating of air.
In 1864 he starts his collaboration with the Ship
Lieutenant Auguste Denayrouze, which patents
in the same year a natural rubber suit for hardhat
divers that leaves free the head and is provided
4 – 1864 – maschera granfacciale in caoutchouc, con due
vetri e, all’altezza della bocca, l’innesto per il tubo in
gomma proveniente dal “regolatore”, utilizzata per lavori
subacquei in abbinamento con l’autorespiratore
Rouquayrol-Denayrouze (da “Trois inventeurs méconnus”,
1980).
4 – 1864 – Full-face mask in natural rubber, with two glasses
and, at the height of the mouth, the insertion for the rubber
pipe coming from the “regulator”, used for underwater
works in combination with the Rouquayrol-Denayrouze
rebreather (from “Trois inventeurs méconnus”, 1980).
