COMPLETE SPECIFICATION.
Improvements in Burners.
I, JAMES GIBBONS, of Jersey City, in the County of Hudson and State of
New Jersey, United States of America, Manufacturer, do hereby declare the
nature of my invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
My invention relates to gas or vapour burners, and has for its object to simplify
the construction and mode of connection of burners of this character, and thereby
promote convenience in thoroughly and quickly cleaning them to assure their most
effective operation.
The invention will first be described, and then will be particularly defined in
claims hereinafter set forth.
Reference is to be had to the accompanying drawings, forming a part of this
Specification, in which similar letters of reference indicate corresponding parts in
all the figures.
Figure 1 is a sectional side elevation of a portion of a gas stove with my
improved burner held thereto.
Fig. 2 is an enlarged side elevation of the burner-stem or mixing-tube and its
flame-cap.
Fig. 3 is a vertical sectional view taken on the line a, a, in Fig. 2.
Fig. 4 is a transverse section of the stem, taken on the liny, y, in Fig. 2.
Fig. 5 is a face view of the gas-inlet nipple of the burner.
Gas or vapour burners commonly used in stoves, heaters, furnaces, or elsewhere
for cooking and heating purposes give considerable annoyance in use by choking
up at their gas and air inlets or passages and at the flame cap or tip by sooty
deposits given off from the fuel they burn and dusty or greasy particles which
accumulate about the parts and which become hard-baked upon the screw or bolt
fastenings usually employed to hold the flame-cap or tip to the burner-stem or
mixing-tube. When these screw or bolt fastenings "burn in," it is very difficult
and often impossible to remove them. Hence the parts of the burner cannot be
dismembered to facilitate convenient and thorough cleaning of it to maintain a
most effective hot blue flame. Burners of this class have also usually been rigidly
and permanently fixed to or within the gas-stove or other support with which they
are used, thus making it impossible to remove them by persons using them and
rendering the cleaning operation all the more disagreeable and uncertain. My
invention fully obviates these difficulties.
The stem or mixing tube A of the burner lies horizontally when the burner is
in use, and at its outer part is enlarged to form a cupped head a and at its inner
part has an opening a' admitting atmospheric air to the stem or tube to mingle or
mix therein with gas or fluid fuel admitted at the back end of the stem through a
suitable nipple or plug. The flame-cap or tip B of the burner is held to the stem-
head a by an interlocking joint and without the aid of screws, bolts, or rivets,
whereby the
cap may easily be removed to allow thorough cleaning of it and the
stem, and more particularly the apertures bat which the burner flames, and which
are shown wholly in the cap B but may be wholly in the stem-head a or in both
barts B a of the device.
I prefer to detachably connect the cap to the burner-stem head or body by a
liametrically-opposite pair of lugs on one part, which are preferably notched or
lotted and engage inclined flanges or ribs on the other part, the lugs C being
preferably on the cap B and the inclined flanges D being on the stem-head a as
clearly shown in Figs. 1, 2 and 3 of the drawings. It is obvious that by simply
urning the cap on the stem-head after they are laid together the lugs will engage

page_text: the flanges, in a manner binding the cap securely to the head, but allowing its
almost instant detachment therefrom when the parts are to be cleaned and as easy
reapplication of the cap in true operative position.
To promote more easy and thorough cleaning of all parts of the burner I make
its stem or mixing-tube readily detachable from its support, and to effect this the
stem is provided at its inner end with laterally-projecting flanges or lugs, which
are engaged by pins or studs on the support. I prefer to form on the burner stem
or tube diametrically-opposite flanges E F having slots e opening in opposite
directions, as most clearly shown in Fig. 4 of the drawings, and whereby when the
burner is slipped onto its gas-supply nipple the flange-slots will engage studs or
pins GG, held in position to receive them, the studs preferably being screwed into
their support and having heads which overlap the outer faces of the slotted
flanges. Instead of using open-ended slots, I may employ larger flanges or lugs
on the burner-stem and provide slots having an enlargement at the outer end to
pass the heads of the studs G through before turning the burner-stem around to
cause the narrower portions of the slots to engage the studs, one of these enlarged
flanges so slotted being indicated by dotted lines in Fig. 4 of the drawings.
In the preferred construction I fix the burner-holding studs or pins G whether
they are headed or not, to the flange or base-plate of the gas inlet nipple F
over which the stem or mixing-tube of the burner is fitted. This nipple, having
said pins or any equivalent shoulders which lock with corresponding shoulders of
the burner-stem when the parts are relatively rotated one on the other, is pro-
vided with any ordinary or approved means for connection of a gas-supply cock
or pipe, said means preferably being an outwardly projecting stem or plug I to
which is adapted to be screwed or otherwise fitted or attached a gas-cock J to
which the main gas-supply pipe K is connected; or, if desirable or necessary, the
gas-supply, pipe may itself be connected directly to the nipple-plug I and the gas-
cock then be otherwise located on the pipe. It is obvious that by thus placing the
studs G on the gas-nipple flange the burner and its nipple are a complete fixture
and the studs are always accurately located relatively to the burner-stem flanges,
which engage them, and the studs are also stronger than they would be if fixed
with considerable difficulty as to precise positions into the wall L of a stove or
other appliance containing or supporting the burner. Furthermore, by putting
the attaching plug I on the nipple base-plate or flange the complete but readily-
dismemberable burner may be connected to the stove or support L by simply making
one hole in its wall to receive the plug to which the gas-supply cock or pipe is
preferably screwed to make a secure connection.
When the burner and its pipe connections are all in operative positions in or on
a stove L or other support, as shown in Fig. 1 of the drawings, the burner-stem
or mixing-tube A may be easily removed from the fixed gas-nipple H by simply
turning the stem around toward the left hand, and either before or after the stem
is thus detached the cap B may be as easily detached from the stem or tube-head
by turning it backward a little to disengage its lugs C froin the flanges D and the
entire burner may then be thoroughly cleaned and the cap replaced and the whole
reset in operative position upon the gas-supply nipple H by any person of ordinary
intelligence and without the aid of tools. The burner may thus be kept clean and
always in condition to give a clear-blue and very hot flame, assuring freedom from
disagreeable odours and promoting economy of fuel and most efficient operation.
As hereinbefore intimated, I am not limited to any particular form of engaging
shoulders at the end of the burner-stem or mixing-tube and on the gas-admitting
nipple entering it, whereby said parts are locked together by frictional contact while
being relatively rotated one on the other. I prefer, however, to use the slotted
or hook-shaped flanges on one part and the headed pins on the other part, which
provide most effective locking-shoulders to retain the burner stem or body-on the
nipple without requiring accurate and expensive fitting of the parts. Neither am
I limited to the use of a projecting stem or plug I on the nipple as a means of
fastening it to the stove, wall, or support, and as a means of connecting the gas-

page_text: supply cock or pipe; but said stem I provides for most easy and secure coupling
of the burner, its support, and the feed-pipe, and has special utility in this respect,
as it requires but one hole to be made in the store, wall or support to receive the
stem or plug, as will readily be understood.
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-A burner comprising a detachable body or stem and a gas-admitting nipple
entering the stem, cach of said parts having one or more shoulders engaging by or
during a relative rotation of one part on the other, substantially as described.
2-A burner comprising a detachable body or stem and a gas-admitting nipple
entering the stem, each of said parts having one or more shoulders engaging by or
during a relative rotation of one part on the other, said nipple also having means
for connection of a gas-supply cock or pipe, substantially as described.
3-A burner comprising a detachable body or stem provided with one or more
lateral slotted or hook-shaped flanges and a gas-admitting nipple entering the stem
and having headed studs or pins engaged by the burner-stem flanges and dis-
engaged therefrom by a relative partial rotary movement, substantially as
described.
4. A burner comprising a detachable body or stem provided with one or more
lateral slotted or hook-shaped flanges and a gas-admitting nipple entering the stem
and having headed studs or pins engaged by the burner-stem flanges and dis-
engaged therefrom by a relative partial rotary movement, said nipple also having
an outer plug or stem for connection of a gas-supply cock or pipe, substantially as
described.
