Application July 26, 1943, Serial No. 496,201 1 Claim. (Cl. 126-2713) 1 2 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 quadrant 54, so that the lever may be latched in different positions to latch the damper 30 in its normally vertical position, its completely closed ' position, or different intermediate positions. In Figure 4, each tube [2 is provided with a damper 56. Each damper 56 is provided with a ciated for effectively destroying the growth crank 58 pivotally connected with the forward simultaneously on both sides of the road bed. end of a rod 60. The rods 60 extend rearwardly In the accompanying drawings: . to positions inside the cab 40 and are operated Figure 1 is a side elevation of a locomotive 10 by levers 62 identical with the lever 46 and its showing my invention applied thereto. associated structure.

Figure 4 is a sectional detail View illustrating The tubes 12 are contoured to lie close to the the manner in which the device is incorporated 16 boiler l4 and extend rearwardly from the ?ange in the Smokestack of the locomotive. 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. Figure 5 is a sectional view of a modi?ed form of weed destroyer control valves. Figure 6 is a view illustrating a control lever, and 20 Figure 7 is a view in side elevation of the for ward portion of the locomotive, illustrating a slightly different arrangement of the tubes for conveying the exhaust to the road bed. 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 tutes a continuation of- the smokestack l8 so that’ 35 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 As shown in Figure 7, the tubes for conveying‘ above the openings 28 when the damper is moved _ the products of combustion and exhaust steam to a horizontal position. Means for rotating the from the locomotive to the road bed, and which damper 30 comprises a crank 36 ?xed to one of are here designated l3, may be arranged to‘ex the shafts 32 and pivotally connected with one tend directly downward from points immediately end of a rod 38 extending rearwardly to a posi-' 50 above the smoke box 22, to points immediately tion inside the cab 40. In Figure 6, the rod 38 passes through an opening 42 in the cab wall 44. A lever 46 is pivotally connected at 48 with a below the cylinders l5 of the locomotive. _At said latter points, the tubes l3 are bent inwardly below the cylinders l5 to position their lower portions in close proximity to the rails 10. The . bracket 50 attached to the wall 44. ‘This lever is provided with a pawl 52 for coaction with a 55 tubes l3 are provided at their lower ends with 3 nozzles I‘! which have\ their discharge ends located close to the rails 10 and which incline downwardly and rearwardly from the tubes at an angle of approximately 45°. Without further elaboration, the foregoing will so fully explain my invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.
