Application December 19, 1935, Serial No. 55,137
2 Qlaims. (Cl. 67-755)
The present invention relates to improvements
in ‘road torches, particularly of the type adapted
to be carried upon vehicles such as trucks for
the purpose of‘ emergency illumination, such
5 torches usually being placed upon the ground
when the?truck is stopped at the side of the road
for repairs so'as' to warn other vehicles. Such
torches are also adapted to use in marking road
constructions, excavations and the like. ' Because
10 of the fact that these torches must be used in the
open‘ in all kinds of weather, it is essential that
the ?ame be protected against extinguishment
by wind, rain and falling'snow. While various
attempts have been made tov producetorche's of
15- this character they have failed when subjected
to extreme conditions, such as very heavy‘rain
fall'ior a considerable period accompanied by
wind, where the direction of the rain was not
straight‘ down, that is, where the rain hit the
20 torch at an angle as great as 45°, and under cer
tain conditions'as‘whenaccompanied by a heavy
gale would hit "the "torch in'an ‘approximately
horizontal direction.

It is an object of the present invention to pro
25 vide a torch in which'the flame will-be complete
ly protected against 'e'xting'uishment‘under’ these
severe conditions, and to'this end it is proposed
to provide rain'a'nd wind baiile means providing
a complete barrier about the wick in avertical
30 direction, a horizontal direction, and in any
angular direction between‘vertical and horizon
tal, and irrespective of which side of the torch
is exposed. A further object is to provide a
road torch in which the sides of the guard‘ pro
vided about‘ the wick have no opening exposed
in a lateral direction, but in which means are
provided whereby‘ the flame may emerge from
the sides to provide a large ‘spreading bright
?ame‘

A further object is to provide for the vertical
exit of ?ame through the top of the guard so as
to increase the illuminatinge?ect, to provide a
?ame which ‘extends to a greater height than
is the case where there is no ‘vertical exit of
45 ?ame, and to provide such a flame in contact
with the top portion of the guard for the purpose
of preventing excessive accumulation of carbon,
the flame consuming such carbon as might other
wise be collected, thereby ‘resulting in‘ a burner
50 of high efliciency, of extreme visibility of the
?ame, and which will not be impaired by ex
cessive carbon accumulation as has been the case
with previous trues of road torches. It is pro
posed tp‘provide a vertical exit .?ame means in
55 the top ofthe guard which at the same time will.
be completely protected against the entrance of
rain and high wind into'the interior of the
burner and irrespective of the angle at which
such rain or wind strikes.
' i
A further object is‘to provide wick holding
means providing an enclosed air-space about the
upper' end of the wick which will be heated by
the burner for the purpose of heating the kero
s'ene or'other liquid fuel prior to burning, and
it is‘ particularly proposed to provide such struc
true which will not cause the sides of the upper
end portion vof the wick to become scorched, or
burned; as has been the case heretofore in those
burners where the wick was supported by a tube
in contact with the wick and which became
heated to a high degree by the ?ame.
' vA further object‘ is to provide improved means
for securing the torch when not in use upon
the truck, or other'structure for which the torch
is intended.‘ Another object is to provide a torch
ofisturdy construction so as to withstand the
rough usage to which the torch may be subjected.
With the above and other objects in view, em
bodiments of'the invention are shown in the
accompanying drawing, and these embodiments
will be‘ hereinafter more fully described with
reference thereto, and the invention Will be ?nal
1y pointed’out in the claims.

sponding parts throughout the several ?gures of
the drawing.
Referring to the drawing, the torch according
to my invention comprises a fuel receptacle
adapted to contain kerosene or other suitable
liquid fuel and consisting of a cup shaped base
portion l0 and a top portion H secured to the
upper edge of the base portion, this top portion
being preferably dome shaped and provided cen
trally with a circular opening l2 in which is en
gaged and secured a burner attaching member
l3, this member being secured by a shouldered
?ange l4 engaged within the opening l2 and
curled over upon the underside. The side wall
of the member l3 has screw threads I5 pressed
therein for the purpose of securing thereon a
protective cap H5 having screw threads at its
lower portion Mia as shown in Fig. 1, this cap
adapted to enclose the burner portion of the
torch when the same is not in use. The top of
the member 13 is ?at and is provided with a
circular opening having inwardly bent segmental
cam ?anges ill and I8 bent downwardly from its
edge, the ends of these ?anges being spaced apart
by cut-outs l9 and 20. The cam ?anges l1 and
I8 are of increasing height from one end to the
other, the low end of one flange being adjacent
ties to the outer surface of the tubular portion
29, preferably spot welding, although they may
be riveted or otherwise suitably secured thereto.
This structure provides a guard in surrounding
relation to the ?ame which is entirely free of any
opening exposed in a horizontal direction, but
which at the same time provides openings for
the exit of ?ame and openings for the entrance
of air, the ?ame exit openings 36 being formed
by the inwardly pressed upper edges of the V
shaped wall portions 35 and the circumferential
lower edge of the upper portion of the guard
formed by the shearing cuts 34. These ?ame exit
openings are disposed in a lateral plane and the
?ame emerges through them by taking a sub
stantially S-shape course. The air entrance
openings 36a are formed by?the lower edges of
the guard and the outer surface of the tubular
portion 29, these air openings being also dis
pose-d in a lateral plane and in alternate arrange
ment with the ?ame exit openings 36, as clearly
shown in Fig. 6. By this arrangement the in~

consisting of a lower shell member having a re
terior of the burner is completely closed in a lat
eral direction, so that the force of wind upon the
burner is baf?ed and at no point directly reaches
the wick. Even under the most severe wind con 30.
ditions the burner will continue to burn without
danger of the ?ame being blown out. The con
duced diameter lower end portion 2| provided in
struction also completely protects the ?ame with
its base with a central wick receiving opening
having an upwardly bent ?ange 22, and an up
in the burner against rain and snow, and this
irrespective of whether the fall of the rain or 35
per portion 23 of greater diameter than the lower
portion 2!, a laterally disposed shoulder 24 con
when accompanied by severe gale conditions
the high end of the other, and areadapted to
removably secure the burner element to the fuel
30 receptacle, as will hereinafter more fully appear.
The burner comprises a wick holding element
necting the portions 2| and 23, and the upper
end of the portion 23 being outwardly offset, as
at 25. A truncated cone shaped cap member 26
is secured upon the upper end of the shell mem
ber, being provided at its lower edge with a
downwardly extending cylindrical ?ange 21 se
cured about the outwardly offset portion 25 of
the shell member by curling over the lower edge
of the ?ange portion 27, as at 28. At the upper
snow is straight down or at a large angle. Even
where the rain might be blown in a horizontal
direction the structure will prevent entrance of
rain to the wick.
40
While it is necessary to have the top of the
burner closed against rainfall, it is also desir
able to prevent the trapping of gases in the upper
portion of the guard and the excessive accumula
tion of carbon. Also it is desirable to supplement
the ?ame emerging from the sides of the guard
side of the cap member there is provided an up
by a vertically emerging ?ame so that the com
wardly projecting cylindrical tubular portion 29
bined ?ames will be relatively higher and there
through which the upper end of the wick 30 ex
tends. It will be noted that the diameter‘ of the
fore more visible at a distance.
For this pur
fully described. At diametrically opposed points
pose I provide a slot 31 in the upper portion of
the guard and over this slot I provide a wind and
rain protector to prevent the entrance of wind
and rain into the burner through the slot 31.
This protector comprises an inclined ?ange 38
disposed along one edge of the slot 31 and hav 55
ing a base portion 39, a shorter inclined ?ange
the lower portion 2| of the shell member is pro
49 extending along the opposed edge of the slot
vided with outwardly pressed bosses 3| and 3|“,
31 and provided with a base portion 4! , end walls
which are adapted to cooperate with the cam
42 and 43, an inclined top portion 44 arranged in
parallel relation to the ?ange 38, and an inclined
top portion 45 arranged in parallel relation to
the ?ange 40. The ?anges 38 and 49 are prefer
ably at an angle of 90° to each other, the end
of the ?ange 40 being spaced from the ?ange 38
and the end of the ?ange 38 being in the plane of 65.
the outer surface of the ?ange 40. The top por
tions 44 and 45 are similarly arranged but offset
to one side so that the top portion 45 is disposed
in a vertical direction above the opening between
the ?anges 38 and 40. In operation the ?ame
tubular portion 29 is greater than the diameter
of the flange 22 so that the wick which is fric
tionally engaged and supported by the ?ange 22
is spaced at its upper end portion from the tubu
lar portion 29, for a purpose hereinafter more
(30
of the guard below ‘these shearing cuts being
pressed inwardly to provide three V-shaped in
wardly extending walls 35, the apices of these
walls being secured adjacent their lower extremi
?anges IT and [8 to retain the burner in place,
these bosses being ?rst engaged through the cut
outs l9 and 23 and the shell member then being
rotated to bring the bosses into Wedging engage
ment with the lower inclined edges of the ?anges
IT and I8. A sealing washer 32 of asbestos or
other suitable material is preferably interposed
between the shoulder 24 and the top of the mem
ber l3.
‘The burner further comprises a ?ame guard,
which is ‘mounted upon the tubular portion 29,
and comprises an inverted cup-shaped member
33, the side wall of which is provided between
its upper and lower ends with a plurality of
shearing cuts 34 of equal length and having their
ends spaced ashort distance apart, the side wall
extends Vertically through the opening between
the ?anges 38 and 40, then at a slight inclination
beneath the top portion 45, and emerges in a
vertical direction through the opening between
the'top portions 44 and 45 as clearly indicated by
2,122,624
the arrow. Despite the vertical emergence of
the ?ame the slot 31 is completely protected
against the entrance of rain either in the vertical
direction, a horizontal direction, or at any angle
between vertical and horizontal. Also wind di
rected against the burner in any direction or
angle will be de?ected from direct entrance into
the slot 31. The ?ame extending through the
top of the burner prevents the excessive accumu
lation of carbon as its heat will consume such
carbon as would otherwise be collected if there
was no provision for vertical emergence of ?ame.
The wick supporting part of the burner formed.
by the shell member 23 and the truncated cone
1.5 shaped member 26 provides an air chamber about
the end portion of the wick which becomes heat
ed su?‘lciently to maintain the ?uid drawn up
by the wick at the proper ?ash point. By spac
ing the tubular portion 29 from the upper end of
20 the wick the wick is prevented ,from becoming
scorched or burned, as is the case with torches
in which a tubular wick holder is tightly engaged
about the end portion, of the wick and becomes
heated to a high degree from contact with the
25 ?ame.
In Fig. 8, I have shown in plan view a blank
from which the protector device for the slot 31
may be formed from one piece of sheet metal,
the top portion 44 having a notch 46 at its end
30 which interlocks with a lug 41 on the end wall
portion 43, the base portion 39 having a lug 48
at its end which is adapted to lock with a notch
49 in the end wall portion 43, and the base por
tion 4| having a lug 50 at its end which lockingly
35 engages with a notch 5| provided in the end wall
portion 42. The protector device may be secured
to the top of the guard by spot-welding the
base portions 39 and 4| thereto, or the same may
be secured by any other suitable means, as will
40 be obvious.
In Figs. 9 and 10, I have illustrated a modi?ed
form of the invention in which the ?ame guard
is removably mounted upon the tubular portion
29. For this purpose the apices of the inwardly
bent V-shaped wall portions 35 are provided
with inwardly pressed lugs or bosses 52 and the
tubular portion 29 is provided with a series of
bayonet slots 53, the locking portions of which
are slightly inclined downwardly, as clearly
50 shown in Fig. 9. By engaging the lugs 52 in
these bayonet slots and turning the guard the in
clined locking portions of the slots act as cams
to tightly wedge the lower edge of the guard
against the upper side of the member 26, thus
55 securely connecting the guard to the wick sup
porting portion of the burner. The removability
of the guard facilitates cleaning or trimming of
the upper end of the wick, cleaning of the guard,
3
lighting of the torch, and also enables the torch
to be used without the guard when desired.
For the purpose of securely mounting the torch
upon the vehicle I provide a band formed of a
pair of semi-circular metal strips 54—54 having
attaching bracket portions 55-55 at their inner
ends riveted together as at 56, and provided at
their outer ends with ears 51-51 adapted to be
secured together by a nut and bolt 58 to clamp
the band about the receptacle Ill. A rib 59 is 10
formed upon the receptacle and engages the up
per edge of the band.
I have illustrated and described a preferred
and satisfactory embodiment of the invention,
but it will be obvious that changes may be made 15
therein, within the spirit and scope thereof, as
de?ned in the appended claims.
Having thus described my invention, what I
claim and desire to secure by Letters Patent is:1. In a torch burner, a wick holder, a ?ame
guard carried by said wick holder having a side
wall and a top wall, said side wall having at its
lower portion a plurality of circumferentially
spaced inwardly pressed portions extending to
the lower edge of the guard, the upper edges of 25
said inwardly pressed portions being severed from
said side wall forming a plurality of ?ame
emergence openings having radially spaced outer
and inner edges, the spaced radially inward por
tions of said side wall adjacent said lower edge 30
being directly engaged with said wick holder
and there being openings between the spaced
radially outward portions of said side wall ad
jacent said lower edge and the wick holder for
the entrance of air.

spaced inwardly pressed portions extending to the
lower edge of the guard, the upper edges of said
inwardly pressed portions being severed from said
side wall forming a plurality of ?ame emergence 45
openings having radially spaced outer and inner
edges, the spaced radially inward portions of
said side wall adjacent said lower edge being di
rectly engaged with said central tubular portion
of said wick holder and there being openings be 50
tween the spaced radially outward portions of
