PROVISIONAL SPECIFICATION left by the said Alfred Julius Boult at the
Office of the Commissioners of Patents on the 17th June 1882.

"IMPROVEMENTS
IN GAS BEGULATORS OR GOVERNORS" [A communication to him from abroad by
Paul Parsy of Lille in the Republic of France, Engineer]
This invention relates to an improved apparatus for automatically regulating the
supply of gas to burners so that the consumption shall be uniform under varying
pressures in the main-supply.
The apparatus consists of a vessel proferably of cylindrical shape. Into the
bottom thereof is screwed the supply pipe the top of which has one or more
recesses or openings whose purpose will presently appear. The lid of the aforesaid
vessel carries on its top a suitable connection to connect the regulator with the
burner and a suitable aperture is made in the lid for the passage of the gas; from
the lid downwards extends an open cylinder or cap. A vessel smaller than the one
above referred to, which may be grooved at its sides is placed within said first
vessel and rests on the supply pipe. The dimensions of the smaller vessel are such
that when it is in its place, an annular space is left between it and the outer vessel
and also between it and the cap on the lid; the latter extends nearly to the bottom
of the inner vessel and has an aperture near the lid.
A cylindrical float fits within the cap so as to be able to move up and down in
the same and on the top of said float is fixed a conical plug which fits into the
gas outlet in the lid.

page_text: The inner vessel is filled or partly filled with a suitable liquid and can be
raised or lowered by screwing the supply pipe further in or out.
to
When all the parts are in place and the apparatus ready for operation, gas will
issue from the recesses in the top of the supply pipe and flow under and around
the inner vessel (that is to say in the space between the latter and the outer one)
and will, the top of the inner vessel being open, exert more or less pressure upon
the liquid. A portion of the gas finds its way through the aperture in the cap
the gas outlet and passes to the burner. The float working in the recess is raised
by the liquid acting by reason of the excess of pressure in the confined annular
chamber over the pressure above the float the latter being constantly reduced by
the gas being absorbed at the burner.

page_text: it to be understood that what I claim and desire to protect under the hereinbefore
in part recited Letters Patent, is :
In an automatic gas regulator the combination of the box A, the trough C the
cylinder D the float F surmounted by the cone k all as set forth and shown.
In witness whereof I the said Alfred Julius Boult, have hereunto set iny
