page_text: The rim on plate or disc I is turned over upon the flange d on the cylinder A² and
thus holds these parts bound together.
A central orifice e is made in the bottom plate I and a similar perforation is made
in the top of the cylinder A at a. Small orifices c c are made in the side wall of the
outer cylinder A2 which the wall of the inner cylinder A' will measurably close when
the pressure of gas that enters the inner chamber A¹ causes it to rise.
The opening a in the chamber A¹ is made of a size sufficient to pass the predeter-
mined quantity of gas to be consumed under the lowest pressure adapted as a standard
of regulation, say four-tenths of an inch water pressure, under such conditions the
hole a would be about one sixteenth of an inch in diameter for five feet of gas per
hour of about six hundred specific gravity larger holes being made for more gas and
smaller holes for a diminished quantity of gas.
The perforations c c &c. in cylinder A have a delivering capacity greater than the
hole a in the cylindrical chamber A¹ and their location is such that the top surface of
the inner chamber A will line with the lower edges of these perforations when said
chamber A' is made to rest upon the bottom plate I.
In operation, the gas that enters the inner chamber A', through the hole e in the
bottom plate I will escape through the orifice a in the top of this chamber.
The delivery of gas will not cause an alteration of the position of the chamber A'
unless gas of unusual pressure which exceeds four tenths of one inch is made to bear
upon the upper interior surface of chamber A' which will lift it and thus diminish the
flow of gas from the holes e by contracting their area.
In Fig. 2 a modified form of pillar or burner shell is shown, this consists of a base E
that is threaded interiorly to fit a fixture, it is flanged at its upper end to form an
upturned lip g, which is adapted to overlap the flange 7 of the upper section D, of
the burner shell and secure it in close connection by swedging it down thereon.
The remaining features of the regulator are similar to that shown in Fig. 1.
In Figs. 3 and 4 a modified form of my gas regulator is shown. The regulator in
this case is provided with a device to prevent a total cut-off of the gas supply to the
tip of the burner which may occur when the pressure is excessive.
I construct the inner. cylinder A' with two or more projecting points on its upper
surface that will abut upon the inner top surface of the outer cylinder A2, these aro
of a proper length to prevent the cylinder from rising above the top line of the orifices c
in the chamber A².
C
This construction will produce a gas chamber above the inner cylinder A' and as
the pressure in this chamber a will equal that in the interior of the chamber A¹ it
follows that the weight of the chamber A¹ will cause it to fall and the openings a be
again effective for passing gas to the burner tip.
In the dotted lines of Fig. 3 the projections are shown as depending from the
inner surface of the top of the chamber A2, the operation of the two methods of
construction are identical. In Fig. 4 this modified form of regulator is shown as
applied to the improved burner shell exhibited in Fig. 2 of the drawings.
In Figs. 5 and 6 views are given of my improved regulator adapted to be inserted
in a burner tip and also a new form of tip and regulator inserted in place in it.
In Fig. 5 the burner tip is of ordinary construction the regulator shown in the
gas burners just described being made to fit its interior cylindrical passage, a
sufficient space being allowed between the opposed vertical wall of the tip and the
cylinder B to permit gas to escape from the openings e in the side wall of this
chamber B.
In Fig. 6 a sheet metal or paper shell is employed to construct the regulator,
the body of the tip is preferably made of sheet metal struck into form the cone
being clamped to the tapering side wall by a returned edge of this side wall B
engaging a flange formed on the cone F a perforated cap E being held in place
by this juncture of the cone and side wall of the tip.
The other features of this tip are identical with the regulator shown in Fig. 5
and also as is combined with the burners previously described.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. In a gas burner the combination with an outer cylinder closed at one end
and provided with gas escape openings in its side of an inner cylinder somewhat
shorter than the outer cylinder and provided with a gas escape opening of less
capacity than the escape openings in the outer cylinder substantially as set forth.
2. In a gas burner the combination with a gas pillar or shell of an outer cylinder
having holes in its side wall and an inner cylinder perforated in its top surface
this opening being of less capacity than the aggregate side openings in the outer
cylinder to produce a gas regulating device in a burner body, substantially as
set forth.
3. In a gas burner the combination with an outer cylinder closed at its upper
end and having side openings, of an inner cylinder provided with a closed end,
this end being perforated with an opening of less capacity than the aggregate side
openings in the outer cylinder, and stops or projections located between the top
of the inner cylinder, and the inner top surface of the outer cylinder to limit the
upward movement of the inner cylinder substantially as set forth.
4. In a gas burner, an outer cylinder closed at one end and open at the other and
having an outlet or outlets in its side wall an inner cylinder shorter than the outer
cylinder, closed at one end and having a hole of less capacity than the outlet in the
outer cylinder and provided with upward projection, in combination with a plate or
cover having an inlet hole through it and adapted to be secured gas tight to the open
end of the outer cylinder substantially as set forth.
5. The combination with a burner tip of a regulator located within the shank of
the tip substantially as set forth.
6. Two concentric cylinders cut, struck, or drawn from sheet metal provided
respectively with gas inlet and outlet one fitting loosely within the other, the inner
cylinder maintained within the outer by a suitable stop, perforated cap or plug, upon
which the inner cylinder rests substantially as set forth.
