My invention relates to the destruction of grass
and weeds along the rails and on the bed of rail
road tracks, and has among its objects and ad
vantages the provision of an improved weed and
grass burner designed to utilize the exhaust gases

l6 and then downwardly between the boiler and
versely of the Smokestack and rotatably mounted
the crosshead guide rods 64. Locomotives of the
driving wheel arrangement shown are such that
su?icient room is available for the tubes l2 when
positioned as shown and between the front driv
ing wheel 66 and the rear truck wheel 68. The
lower ends of the tubes I2 extend to positions
within two or three inches of the rails 10 and
are bent rearwardly to angles of about 45 degrees
from the vertical. The ends of the tubes are also
bent outwardly in substantially the same degree.
In operation, the smokestack l8 may be closed
to causethe hot gasesv to exhaust through the
tubes [2. Because of the arrangement of the
discharging ends of the tubes I 2, the hot gases
are exhausted onto the road bed along‘the rails
10 to effectively destroy any growth adjacent and
about the rails.
Figure 5 illustrates a modi?cation in that slide
valves 12 are employed in lieu of the pivoted
valves 56. The valves 12 are slidably mounted in
guides 14 ?xed to the ?ange 16 corresponding to
the ?ange IS. The tubes 18 are ?xed to the
guide 14 and have communication with the ?ange
l6 through the medium of ports 80 in the guides
14. Each valve 12 has a control rod 82 pivotally
connected therewith, which control rods corre
spond to the rods 60 and may be actuated in the
in bearings 34. This damper is of such diam
same manner.

In the embodiment of the invention selected 20
for illustration, I make use of a steam locomotive
I 0 of a conventional type.
Two tubes l2 are .
mounted on the locomotive near the forward end
of its boiler l4. The tubes l2 are arranged on
opposite sides of the boiler and each has one end 30
attached to a ?ange l6 ' comprising the base
‘structure of the Smokestack [8. The ?ange I6
is provided with a ?ange 20 riveted to the smoke
box 22 of the locomotive. The ?ange l6 consti

the latter has communication with the smokebox
22 in the usual manner.
In Figure 4, the tubes l2 are ?anged at 24 and
riveted at 26 to the ?ange l6. This ?ange has
openings 28 coaxial with the tubes [2. Inside the 40
smokestack I8 is mounted a damper 30 which is
provided with coaxial shafts 32 arranged trans
eter as to completely close the Smokestack I8 45

passes through an opening 42 in the cab wall 44.
A lever 46 is pivotally connected at 48 with a

latter points, the tubes l3 are bent inwardly
below the cylinders l5 to position their lower

by applying current knowledge, readily adapt the
same for use under various conditions of service.
