FIRE LIGHTER
Sherman Clevenger, Cleveland, Ohio
Application November 11, 1935, Serial No. 49,243
1 Claim. (Cl. 158—10)
This invention relates to ?re lighters and more
especially to a lighter in the form of a gas torch
that is adapted to be positioned beneath the grate
of a stove or furnace for the purpose of igniting
the fuel thereon.
It is one of the objects of the invention to pro
vide a lighter that will be simple in construction,
e?icient in operation and convenient to use.
A further object of the invention is to provide a
10 lighter that will be adapted for use with various
types of grates and that will also be so con
structed that it will remain in any position in
which it is placed under a grate.
Other objects of the invention and the fea
15 tures of novelty will be apparent from the fol
lowing description taken in connection with the
accompanying drawing, of which
Fig. 1 is a perspective view of a device embody
ing my invention.

Fig. 2 is a vertical section through a stove
showing one form of lighter in position therein.
Fig. 3 is a view similar to Fig. 2, but showing the
use of the lighter in a stove having a different
type of grate.

Fig. 4 is a view similar to Fig. 2, but showing
the lighter and its support in position beneath
the grate of a furnace.
Fig. 5 is a longitudinal section through the
lighter shown in Fig. 1.

.
Fig. 6 is a transverse section on the line 6-6
of Fig. 5.
Fig. '7 is a transverse section on the line 'l—-'| of
Fig. 5, and
Fig. 8 is a transverse section on the line 8—8
of Fig. 5.
Referring to the drawing, it will be seen that
my improved lighter consists of a tubular cast
ing, the central portion of which is of rectangular
cross section,-as indicated at ID. The upper and
40 lower surfaces of this rectangular portion are
corrugated, as indicated at H and I2 and the
inner end of the lighter is turned up substan
tially at right angles to the longitudinal axis of
the lighter, as indicated at I3, and the terminal
45 portion of this turned-up end is tapered, as in
dicated at M, and provided with a circumfer
ential series of discharge ori?ces l5. It will be
noted that the terminal portion extends consid
erably beyond the ori?ces !5 so that, when the
50 lighter is used in a stove having a grate of the
form illustrated at IS, in Fig. 3, the end of the
tapered portion is will engage with the under
side of the grate and space the ori?ces l5 away
from the grate so that the latter will not inter
55 fere with the discharge of the gas mixture from
any of the orifices. The opposite end of the
lighter is enlarged, as indicated at I1, and pro
vided with air inlet ports I8 and a central screw
threaded opening to receive the nipple I9 to which
a supply hose 2!! may be connected. This supply 1
hose will be of suitable length to extend to the
valved end of a gas supply pipe 2| which may be
located in any convenient relation to the stove.
‘As will be noted from Fig, 3, the lighter is
adapted to rest on the erge of the ash pan of the 10
stove, as indicated at 22, and the portion of the
lighter which projects exteriorly of the ash pan,
together with the hose thereon, will be sufficient
to hold the lighter with its up-turned end in
engagement with the under side of the grate I6.
15
In Fig. 2 I have illustrated the lighter in position
in a stove having triangular grate bars 23 be
tween which the up-turned end of the lighter
is adapted to be arranged. In this case the light
er also rests on the ash pan, as indicated at 24, 20
and the corrugated upper surface I I of the lighter
will engage one of the grate bars l3 and the
lighter due to the weight of the hose on its outer
end will thus be held in position, as explained
above.
25
In cases where there is no ash pan in the stove,
or in the case of a furnace, it is necessary to sup
port the lighter in a different manner than shown
in Figs. 2 and 3. For such cases I secure to the
lighter a supporting device consisting of a strip 30
of relatively soft steel or iron having a portion 25
which is arranged on the upper surface of the
lighter and adjustable longitudinally thereon. A
clip 26 secures the support to the lighter and is
clamped in position by means of a bolt 21.
The 03 Or
outer end portion of the support is provided with
a return bend 28 the terminal portion of which is
bent at right angles and formed into a loop 29
which is adapted to engage the shaft 30 of a grate
bar, as shown in Fig. 4. In this way the lighter 40
may be suspended beneath the grate 3| and the
adjustability of the support longitudinally of the
lighter adapts the device to furnaces of different
size so as to make it possible to position the
ori?ces l5 beneath the center of the grate. By 45
making the support of relatively soft steel or iron
the bent portion 28 thereof may be conveniently
positioned to locate the lighter at the proper ele
vation with reference to the grate, and the loop
29 may be bent to conform to the size of the shaft 50
of the grate bar, thus making it possible to adapt
the support to various makes and sizes of fur
naces and stoves.
In using the lighter for a stove having an
ash pan (see Figs. 2 and 3) the ash pit door 32 is 55
