I, ANDREW LINNERE DOWIE, of Glasgow, in the County of Lanark, North
Britain, Merchant, do hereby declare the nature of the said Invention for
IMPROVEMENTS IN GAS BURNERS AND IN PRESSURE REGULATING APPARATUS FOR
THE SAME," to be as follows, that is to say :-
This Invention relates to the arrangement and construction of gas burners,
in such a manner as to insure the obtainment of a particularly pure and
brilliant light, together with great economy in the consumption of gas. The
top of the burner is bell-shaped, or rounded off with a pretty broad flange all
round. Through this flange inclined holes are bored up from beneath in
such a way as to conduct jets of air diagonally into and across the gas flame;
this keeps up an efficient supply of atmospheric air, and the flame burns with
superior brilliancy. According to another modification of burner the top of
the burner is formed by means of two fine saw cuts, so as to present two
diagonal or inclined gas thoroughfares. These thoroughfares are separate or
widely apart at their lower end, but they join into a single cut at the top where
the gas is consumed. This form produces two diagonal or inclined sheets of
flame. A flange is also formed upon the burner as in the former instance, and
inclined holes are drilled through it, so as to admit air between the two sheets
of flame. In this way air is plentifully supplied both to the interior and
exterior of the flame, and a peculiarly brilliant flame is produced.

page_text: This Invention also relates to the arrangement and construction of the
sockets or holders, in which gas burners are set, and to apparatus or details
contained within such sockets for the purpose of regulating the flow or supply
and the pressure of the gas at the point of combustion. The improved sockets
are cast in brass or other suitable metal in two separate sections which are
screwed together. The lower section consists of a tubular portion of small
diameter which fits into the end of the gas pipe. The extreme lower end of
this tube is formed with three or other number of angular faces in each of
which is bored a small hole, so inclined as to diffuse or spread about the
entering gas in the interior of a conical chamber which forms the upper end
of this lower tubular piece. The upper section of the chamber or socket is
formed with a cylindrical chamber at its lower part where it is screwed on to
the top of the lower section, and at the top of this cylindrical portion is a
narrow passage or neck opening into the interior of a spherical chamber in the
top of which is the recess or socket for the burner. The upper portion of the
bore of the cylindrical chamber is of conical form, and in it there is placed
a perforated disc of pasteboard or other suitable vegitable medium, and beneath
this disc is a disc of thin cloth or other suitable animal medium or material.
Or instead of this permeable medium a disc of perforated zinc or other metal
may be used in conjunction with a disc or discs of fine flannel or other
permeable fabric. The entering gas is diffused across the interior of the lower
and cylindrical chamber beneath the two permeable discs within it, and it then
escapes through the narrow neck passage above into the interior of the spherical

way the unsteady rush of gas is checked and subdued, the flame burns with
a clear and brilliant light, and the consumption of gas is greatly reduced.
