WILLIAM HARPIN, 327, Abbeydale Road, Sheffield, Gasfitter & Brassfinisher,
do hereby declare the nature of this invention to be as follows:-
Instead of the usual one-hole gas burner in each of the "fingers" or tubes of
gas fires, I use a burner with two or more (preferably four) holes, to ensure a
better mixture of the gas with the air, and so obtain more perfect combustion and
greater heat.

"
The fingers' or tubes are secured to the burners in the ordinary manner,
but instead of such "fingers" or tubes being straight I make them bent or curved
at the lower ends, that is the ends fitted on the aforesaid burners.
The aperture or orifice, called the "air chamber" provided for the admission
of air to the tube or "finger" to mix with the gas, is, in my invention placed on
the lower side of the bend or curve, thus permitting any dust, soot, or other
foreign matter to fall through the said orifice or air "chamber" instead of onto
the burner, and thereby preventing any choking or stoppage of the holes in
the burner.
"
The "fingers or tubes and burners may be made of any suitable material
preferably brass.

Burners for Incandescent Gas Fires.
I, WILLIAM HARPIN, of 327, Abbeydale Road, Sheffield, in the County of York,
Gas Fitter and Brass Finisher, do hereby declare the nature of this 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 which relates to improvements in and in connection with gas
burners or jets for incandescent gas fires consists of main feed pipes fixed under-
side the ordinary grate with loose burners or jets constructed in such a manner
that they may be easily removed without the aid of tools or skilled labour to
facilitate the cleaning of same as they become filled with dust or other deposit
and to the general arrangement of burners which are not fixed in a vertical
position as heretofore but which shoots out from the main feed pipe at an angle,
this arrangement allows of the air inlet being in a line with the vertical tube at
its lower end and provides for the dust falling upon the floor, and not upon the
fine perforations in the base of the burner.

page_text: In order that my invention may be properly understood and readily carried into
effect, I will now proceed to describe the drawings herewith annexed.
Fig. I of the accompanying drawings is a plan of a fire grate main feed pipe
shown on the underside and the burners projecting through the openings in grate.
Fig. II is a front elevation projected from Fig. I showing the main feed pipe
on floor with burners projecting upwards & through the grate.
Fig. III is a cross section of main feed pipe with burner & nipple fixed in
place as shown on Fig. II.
Figs. IV, V, and VI, are front side and back view of nipple which connects
the burner tube to main feed pipe.
A, is the stove bars. B, is the grate. C, the stove. D, main feed pipe.
E, burner tube. F, nipple with four fine perforations, see Fig V. G air holes
at lower end of burner tubes.
The main feed pipe D which is constructed of suitable tube and formed in
one straight piece as shewn on drawings annexed or which may be bent to suit
fire bars of a convex front as is sometimes the case, and which has the terminal
end stopped up, this tube is bored to receive the brass nipples F, at such distances
as will suit the openings of the grate & the number required for size of fire.
The burner tubes e, which are suitably bent at the lower end fitted upon the
nipples F, without any screw thread being only fixed in place by slight pressure
so that they may be easily removed from time to time for cleaning them out.
These tubes are provided with one air hole as shewn, through which a suitable
quantity of atmospheric air may be injected with the gas.
The arrangement of this air hole and the manner in which the tube is fixed to
nipple allows most of the dust to fall away from the burner and a ready means
of cleaning same.
The nipples F, which are preferably made from brass or other suitable metal
is screwed as shewn on Fig. V at one end, and have plain nipple to receive
burner tube at the other end with milled or hexagon collar in centre to fix same
into feed pipe. The front or plain nipple has inserted into it a thin piece of
brass sheet with four fine holes through as shewn in Fig. IV for the purposes
of spreading the gases.
In case any one of the burners showing insufficient flame the burner tube e
may be instantly lifted off and cleaned out at will, so that one uniform flame
can be constantly spread over the whole grate.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
:-
I. The construction of the brass nipples F, and position of same in connection
with main feed pipe not being on the top side as heretofore substantially as
herein before described and shewn on the accompanying drawings.
II. The arrangement of bent burner tube E, and the portable fitting of same
to nipple F, and position of air hole, substantially as heretofore described and
shewn on the accompanying drawings.
