Improvements in and relating to Burners for Incandescent Gas
Lights.
I, ALBERT HENRY PETEREIT, of 120, West 102nd Street, New York City, New
York, in the United States of America, Master Mechanic, do hereby declare the nature
of this invention, and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement, and
accompanying drawings, that is to say: -
This invention relates to an improved burner for incandescent gas lights in
which all the parts can be so constructed that they can be readily assembled,
being formed of integral pieces of metal, and in which the burner is constructed
in such a manner that a uniform supply of gas and air to the mantel is obtained
whatever be the pressure of the gas; and the invention,consists of an incan-
descent gas burner in which the burner proper is provided with means for regula-
ting simultaneously the supply of gas and air so that a uniform proportion of
the gas and air mixture is supplied to the incandescent mantel for the various
gas pressures.
The invention consists further of the peculiar construction of the gallery for
supporting the chimney and cup and of the novel construction of the burner
top which also serves for the support of the mantel supporting rod.
The invention consists further of the special construction of the chimney and
shade-supporting uprights, and lastly, of some details of construction which
will be fully described hereinafter and finally pointed out in the claims.

Referring to the drawings, A represents the burner portion proper of my im-
proved incandescent gas light which is provided at its upper end with an en-
larged cylindrical mixing chamber A¹ and at its lower end with a valve B for
supplying the required proportionate quantity of gas and air to the mixing-
chamber of the burner. A tubular shank A2 is arranged between the mixing-
chamber and the valve B, the upper end of the tubular shank being covered by
means of a convex diaphragma of wire gauze through which air and gas sup-
plied to the tubular shank is compelled to pass, until it is thoroughly mixed,
on its way to the mixing-chamber A¹. The tubular shank A2 is formed of two
sections, the lower shouldered section supporting the valve B while the upper
section is formed at the lower end of the mixing-chamber, as shown clearly in
Figure 9. The upper end of the mixing-chamber is closed by a diaphragm D
that is provided with tapering openings near its circumference, said diaphragm
being applied by means of radial downwardly-bent strips d to the upper end of
the mixing-chamber. The upper end of the mixing-chamber is provided with
exterior depressions into which the ends of the downwardly-bent retaining
strips are sprung so that the diaphragm D is firmly held in position at the
upper end of the mixing-chamber, as shown clearly in Figures 9 and 10. The
central portion of the diaphragm D is made concave and provided at its centre
with a downwardly-extending socket d' that serves as a support for the rod m
on which the incandescent mantel M is supported.
The diaphragm D is also formed with circumferential outlets or notches ³,
(Figure 10), in contra-distinction to the ordinary perforations provided for the
escape of the combined gas and air, said circular perforations tending to produce
smokiness, a tendency which the present form and arrangement of radial peri-
pheral openings effectually counteracts.
The external surface of the mixing-chamber A¹ is formed with a series of studs
or projections d (Figure 16) for the purpose of centralizing the lower end of the
mantle M, so as to afford an annular draft space between the mantle and the
mixing chamber or reservoir A¹. These projections are preferably, though not
necessarily formed integral with the cylinder A¹, being stuck up thereon as
during the formation of the cylinder.
The valve B is constructed of a gas supply tube C, a stationary perforated
diaphragm b, a movable disc B₁, the central portion of which has an opening
adapted to co-operate with the diaphragm in controlling the admission of gas,
and the outer portion of which 2 is provided with openings b³, which are adapted
to co-operate with another member of the valve, namely, a hood B2, in controlling
the admission of air through openings in the lower part of the tubular
shank A².
The gas supply tube C, Figs, 13, 13, is provided with a number of vertical
slots g of uniform depth, separated by uprights or projections j. The portion
of the tube which forms the projections ; is reduced in internal and external
diameter, thus forming an internal seat for the diaphragm b, and an external
seat or support for the disk 13. This portion is also internally screw-threaded
to receive the lower part of the tubular shank A².
The diaphragm b, Fig. 13, is of thin metal, of size to fit the seat provided for
it in the gas supply tube C and is provided with one or more tongues h which
fit in the openings g and hold the diaphragm in place. The diaphragm is also
provided with small openings for the admission of gas.

page_text: The disc B', Figs. 9, 12 and 14, is provided at its central portion with an open-
ing 66, the shape of which is adapted by the partial rotation of the disc B₁ to
open and close the openings in diaphragm b (Figure 13); surrounding this central
opening is an annular opening subdivided by radial arms and forming a num-
ber of separate openings gl adapted to fit over the projections of the gas supply
tube C, while the arms g fit into the slots g of the said tube C. The arms 9 are
made narrower than the slots y to permit of the partial rotation of the disk B'.
The entire central portion of the disc B¹ is struck up to provide for the seating
of the disc upon the tube C, the outer portion 63 of the disc B¹ is provided with
a plurality of elongated openings 63 for the admission of air, which co-operate
with the radial passages B of the hood 133.
The hood B is formed of a ring or tube B from which depends the hood
proper which is corrugated to form a plurality of radial passages or chambers B.
These passages correspond in number and arrangement to the openings 63 in the
disc B¹.
In assembling the parts of the valve B the diaphragm bis placed over the
opening in the tube C the tongues h resting in the slots g. The disc B¹ is then
adjusted over the projections upon the end of the tube C, the arms g² falling
into the slots g.
The tubular shank A² is then screwed into the internal screw
threads upon the projections of the tube C and is there secured by a pin b.
The ring of the hood 132 is then slipped over the tubular shank A2 and down
until the lower portion of the hood 13 rests upon the outer portion 63 of the
disc B', it is then secured to the tubular shank A2 by a set screw B. The tubular
shank A is provided with openings which are covered by the hood B2.
The disc is provided with a milled edge which permits the disc to be
readily adjusted by hand. There is also provided at the margin of one or more
of the openings 6 small projections 6' that abut against the lower edges of the air
passages B and thus limit the rotation of the disc in either direction the supply
of gas being shut off by the partial rotation of the disc 132, the openings in
diaphragm are uncovered, and gas is admitted, and at the same time the open-
ings. in the outer portion 62 of the dise B₁ are made to coincide with the air
passages B in the hood 132 and air is thus admitted through said air
passage
the openings to the tubular shank A, thence to mix with the gas in the mix-
ing chamber A
and
The admission of gas and air being both controlled by the one means they are
kept in proper proportion to each other whatever the gas pressure, whereby a
better and more effective light is obtained.
An alternative method of operating the main diaphragm 131, is illustrated in
Figures 16, 17 and 18, in which lugs S2, S2 project downward from the disc and
engage with the short arm S¹, of a rock lever S, operated by means of chains S*,S*,
or equivalents.
In order to limit and control the movement of the main diaphragm B', with
accuracy, an upwardly projecting lug $, is provided thereon to form an abut-
ment or contact for the ends of screws S, ST, engaging with female screw threads
in adjoining radial air tubes 132. These screws oppose each other, so that the
play, or extent of motion of the lug S, and consequently of the main diaphragm B³,
may be prescribed by them for the purpose of regulating both the maximum
and minimum size of the flame.
A feature of the invention in this connection consists in making the lugs S, S²,
and $5, integral with the main diaphragm B¹, as shown in Figures 19 and 20,
by which it will be seen that the lugs are stamped out of the blank and after-
wards turned up into position.
To the tubular shank A2 of the burner proper, below the mixing-chamber A³,
is applied a galley G which is made in one integral piece with its cup-supporting
brackets G¹, being preferably stamped from one piece of sheet metal and pro-
vided with the required openings y, nicks y¹ and projections y², so as to form
connection with the shade-supporting uprights F. The lower ends of the up-
right rods F are attached by a ring f to the shank of the burner as shown in

page_text: Figure 3. The details of connection between the uprights F and the gallery G
are clearly shown in detail in Figures 6 and 7, and permit the ready connecting
of these parts when assembling the different parts of the lamp. The uprights F
are provided at some distance from their upper rods with recesses f¹ and inwardly-
projecting ribs that retain a connecting-ring F2, said ribs passing over the inner
surface of the ring F and holding it firmly in position on the uprights, as shown
clearly in Figure 5. To the upper ends of the uprights F are applied the shade-
supporting clips F3 which are provided with oblong perforations in the upper
clip portions, and inclined outwardly-extending arms f³, as shown in detail in
Figure 8, said clips being clipped over the upper ends of the uprights F until
they are supported on the shoulder formed in the same.
In order to prevent side drafts from striking the air mixing-chamber and
rendering the light unsteady a draft guard H, Figure 1, may be sleeved upon
the tubular shank A². This draft-guard is substantially cup-shaped and is
stamped out of thin sheet metal, and extends upwardly encompassing the lower
portion of the air-mixing-chamber A¹.
The modification shown in Figure 15 differs from the principal construction
in forming the gas supply orifices in a transverse partition which is fixed or
integral within the gas supply-tube near its upper end. The main diaphragm B¹
is sleeved upon the upper portion of the said gas supply-tube and rests upon a
ledge formed thereon so as to revolve freely about the same. In this construc-
tion the separate stationary diaphragm shown in Figure 13 is not required.
The air supply only is regulated and this is accomplished in the same manner and
by the same construction as above described in the principal form.
My improved incandescent gas lamp has many advantages among which may
be mentioned the quick and convenient assembling of the parts owing to the fact
that the various parts are easily detachable and by reason of their construction can
be quickly assembled and locked in position. The novel construction of the
valve permits the perfect regulation of the supply of gas and air to the burner
proper regardless of the greater or smaller gas pressure so that the proper pro-
portions of air and gas are automatically obtained and the supply both of the
air and gas simultaneously regulated by the turning of one valve-diaphragm.
The simple construction by which the mantel is supported in the burner top
permits the ready removal of the mantel for the purposes of cleaning, repairing
or renewing the same. The various parts are produced by special dies in such
a manner that they can be easily and quickly assembled with little hand labor
thus materially reducing the cost of manufacture.
