SPECIFICATION forming part of Letters Patent No. 678,621, dated July 16, 1901.

Application filed March 14, 1900. Serial No. 8,682. iNo model.)

To all whom it may concern:

Be it known that we, SAMUEL BURKE HYNns and WILLIAM NEWTON Bnsr, citizens of the United States, residing at Los Angeles,

, bridge-irons, fish-plates, and other irons for the purpose of bending or straightening them.

Another object of our invention is to provide a railway-track f urn ace which can be used at pleasure for exterminating the weeds and grass on the road-bed or the growth upon embankments, culverts, and bridge-approaches.

In order to conveniently eradicate the growth along and at the sides of the road-bed, it is necessary that a large body of intense flame be projected upon the growth to bedestroyed; and with this object in view our railway-road furnace comprises a refractory reverberatory nozzle having a downwardlyextending passage terminating in a slotshaped opening and one or more powerful hydrocarbon-burners, each located at the inlet end of the nozzle to supply the nozzle with a large body of flame. The reverberatorypassage chamber of the nozzle is preferably tapered from the inlet toward the outlet end, so that the body of flame is gradually condensed as it approaches the outlet. The outlet is preferably'of a width to extend fully across the track and about a foot outside the rails, so that as the furnace when in operation is run along the railway the flame will be positively directed against the growth between the rails and ties.

In carrying out our invention we prefer to provide a fender extending from the outlet of the nozzle in the direction in which the flame is projected and at each side, so as to confine the flame to the track after it has left the nozzle, thus making the action of the fire more effective to destroy the weeds and grass. The

fender also largely prevents the winds from driving the flame to one side or the other. The fender is preferably in independent refurnace.

which is independently adjustable and removable. We also provide a removable guard below the nozzle, between the inlet and the outlet ends thereof, to shield the flame from the action of the air which would otherwise tend to prevent the flame from reaching the ground edectively.

In order to use the apparatus for destroying the growth on the sides of embankments, the nozzles may be mounted on a turn-table which is carried by the truck-frame of the The nozzle is preferably pivoted on an axle which lies in a horizontal plane, so that the outlet end of the nozzle may be raised and lowered to cause the flame to be discharged horizontally or downwardly in an inclined plane at will. This swivel arrange ment also enables the operator to turn the nozzle to throw the flame more to the windward side of the track in case the breeze is so strong as to require this to be done in order to counteract the deflection of the flame. The side fenders are preferably supported by flexible connections in order to allow this deflection of the reverberatory nozzle while the fenders are in operative position. In actual use with the fenders in place it is found that as the train runs forward the flame will extend rear wardly from the fenders about twenty feet and that in passing around curves it becomes necessary to turn the nozzle slightly in the direction of the radius of the curve. One purpose of the swivel arrangement is to allow this to be done, so as to bring the flame to the required place for doing effective work at the curve. When the curve has been passed, the operation will again bring the nozzle to a straight position relative to the body of the car.

The accompanying drawings illustrate our invention.

Figure I is a side elevation of ourinvention as applied with a f urnace-nozzle which is pivoted upon a horizontal axis. Fig. II isaplan of the same. Fig. III is a fragmental View of the invention as applied with a turn-table. The nozzle is shown turned sidewise to direct a body of flame down the sides of an embankment. The removable fenders are omitted from this View, for the reason that they will ordinarily be detached when the nozzle is turned into the position shown in these views; but it is to be understood that the fenders will be attached for ordinary work along the road-bed andin cases where the deflection of the nozzle is not so great as to interfere with the fender. Fig. IV is a plan view of the appliance as shown in Fig. III. Fig. V is a section of the nozzle on line V V, Figs. III and IV, with the parts arranged to direct the flame outward through the axial outlet. Fig. VI is a fragmental mid-section of the outlet end of the nozzle arranged to direct the flame at an angle from the axis of the nozzle-chamber. Fig. VII is a plan view showing the machine furnished with a turntable with the parts in position for going around a curve.

1 indicates a refractory nozzle having a down wardly-slanting passage-chamber 2, with an outlet 3 at the lower end and a burner 4, located at the upper end of said passage, to supply the same with a body of flame.

Any number of burners maybe used. One burner may be sufficient or more may be used, if required. In the drawings we have shown two burners 4, and we have also shown the internal passage or chamber divided by a wall 5; but it is to be understood that the wall may be omitted or may be made sectional to allow the flame to pass from one side to the other of the chamber or passage. We prefer to use the two burners and to employ the partition-wall 5, for the reason that the wall 5 gives strength to the refractory lining of the chamber. The furnace-nozzle is preferably composed of a metal shell a, a fireclay chamber-body 1) inside the shell, and a non-heat-conducting lining c, of asbestos or other suitable material, between the fireclay chamber-body and the metal shell. A very high heat is to be produced within the chamber, so that the chamber-body, which is preferably made of specially molded firebricks, will become red or white hot, and the external metal shell CtlS necessary to hold the chamber-body intact; and the asbestos filling or lining between the refractory chamberbody and the metal shell prevents the destructive heating of the shell, which would otherwise warp the same and injure the nozzle.

The nozzle-chamber passage 2 is preferably arranged slanting and tapering downward, and the burner or burners are of great capacity, so that the flame produced will reverberate within the chamber-passage 2 to intensely heat the refractory Walls thereof and produce an intense heat and flame which will issue from the outlet 3 under considerable pressure and will be projected forward and downward against the earth in such a way as to be most effective for the destruction of growing grass and weeds. The extreme heat of the reverberatory chamber and the thorough commingling of air and the vapors from the hydro carbon by the reverberatory action causes a practically perfect combustion of all the oil and prevents all loss from escape of unconsumed gases or smoke.

Our invention is not confined to the work of destroying vegetation along the road-bed, and when it is desired to heat surface-bent rails or anyironwork which is required to be heated it is desirable that the nozzle may be adjusted to direct the flame upon the ironwork which is to be heated. For this purpose and for convenient adjustment when not at work the nozzle is pivoted by trunnion-bearings 6 to a frame 7, carried by a truck 8.

9 indicates a quadrant-lever cooperating The noz-.

low the outlet 3, which is of a slot shape, to

extend fully across the track.

10 indicates means for introducing a forced draft into the nozzle-chamber, so as to cause a large body of intense flame to issue from the slot-outlets 3 at a high pressure when this is desired. In the drawings the means for producing a forced draft is indicated by the pipe 10, which leads from an air-compressor or fan. (Not shown.) We prefer to use a hydrocarbon-burner, although it is to be understood that any burner which may be found suitable for the purpose may be used without departingfromourinvention. Itisimportant, though, that the refractory chamber be filled with a body of flame, so that the chamber will be highly heated, thus to produce a high degree of combustion of the oils and gases while passing through the chamber, so that the flame and heat emitted by the nozzle will be sufficient to destroy the green growth in a minimum period of time.

The heat that issues from the nozzle will be found highly effective for heating surfacebent railway-rails or bridge-irons, which are of considerable length and would otherwise be difficult to be properly heated unless taken to the shop. The tapering form of the passage serves both to condense the flame and to produce the requisite pressure and also to direct the flame outward to the desired point.

It is desirable in some instances that the flame shall be directed laterally of the track, so as to destroy the growth on the sides of embankments at bridge approaches. For this purpose a turn-table 11, carried by the frame 7, Figs. III and IV, is provided, and the refractory nozzle ispivotally mounted in said turn-table, so that the nozzle can be turned sidewise of the track, as indicated in said Figs. III and IV.

12 and 14 indicate the fender formed in three sections, two side sections or fenders 12 being provided to extend along the sides of the path of the flame which issues from the outlet of the nozzle, and the top section or eraser fender 14 being arranged extending from the nozzle above the outlet of the nozzle. The side sections 12 of the fender protect the flame from the action of side drafts of air and concentrate the flame along the track. The top fender-section l l prevents the flame from lifting from the ground, and thus causes the flame to act with the greatest efficiency upon the growth to be destroyed. Suitable means are provided for raising and lowering the fender. These means consist of flexible connections 15 for the side sections 12, respectively, which connections pass over pulleys 16, secured to the frame 7, and are operated by rods 17, one for each of the connections. Preferably a connection 15 is placed at each end of each of the side sections.

18 indicates connections fastened to the top fender 14 and connecting the same with cranklevers 19, which are operated by rods. The several rods 17 and 20 are carried to the platform 21 of the frame 7. These several rods are preferably provided with ratchet-teeth, as at 22, to catch upon a tie-rod 23, used between the two trusses 2% of the frame 7.

In Figs. V and VI the nozzle is shown with two outlets 3 and 31. The outlet 3 extends as an axial continuation of the chamber or passage 2. The outlet 31 is a downward extension of said chamber or passage. 32 indicates means for closing the outlet 3, and 33 indicates means for closing the outlet 31. So long as it is preferred to allow the flame to be emitted through the outlet 3 the closure 32 will be removed and the plug 33 will be inserted in the outlet 31 and fastened by the bolts 34, which pass through lugs 35, which project from the nozzle, and said bolts are secured by nuts 36. Then it is desired to project the flame directly downward through the outlet 31, the closure 32 will be applied to close the outlet 3, and the plug 33 will be withdrawn from the outlet 31 so that the flame will be directed downward substantially at right angles to the axis of the nozzle passage.

37 indicates an air deflector or fender arranged below the nozzle to protect the outlet end of the nozzle from the action of any air which would be forced under such end of the nozzle by the action of the forces when the nozzle is moved forward over the track. This deflector forces the air sidewise and pre vents it from coming beneath and buoying up the flame which issues from the nozzle. When the apparatus is run over the track, the advance of the deflector 37 produces a partial vacuum underneath the front end of the nozzle, so that the flame can be effectively directed down on the growth to be destroyed.

38 indicates a lever for operating the air shield or deflector 37 to raise or lower the front end, as may be found desirable in the practical operation.

39 indicates a rod for operating the lever 38.

In practical operation the apparatus will be drawn along the track in the direction of the arrow, a supply of oil being provided in a tank which may be mounted on the frame 7, as indicated by the tank 40, or which may be the oil-tank of a supply oil-tank car. (Not shown.) The. steam for the hydrocarbonburner will be brought from the locomotive (not shown) through a hose 41. The air for forced draft may also be brought from the locomotive through the pipe 10, which opens into the inlet end of the refractory nozzle.

42 indicates the pipe through which oil is supplied to the burner.

WVhen it is desired to heat railway-rails to straighten or bend them, the side fenders may be elevated out of the way or entirely removed. The rails and ties of the track will be covered with earth and the rails to be straightened or bent will be brought across the track in front of and as close to the outlet-nozzle as is requisite and the flame will be directed upon the rails to heat them. The same method is pursued in heating bridgeirons, fish-plates, or any other iron to be heated.

The speed at which the apparatus will be moved over the track will depend upon the intensity of the flame and upon the luxuriance of the growth to be destroyed. When it is desired to destroy growth on the sides of embankments or at bridge-approaches, the nozzle, mounted as shown in Figs. III and IV, may be swung around by turning the turntable, and the flame may thus be directed to and down the sides of embankments or bridgeapproaches.

lVhen not in use and when coming to and from the work, the fenders are raised as high as possible and the outlet end of the furnacenozzle is raised and the nozzle brought as near to a horizontal position as possible.

The opposite ends of the top fender 14. can be raised and lowered, respectively, at will, and the opposite ends of the side fenders 12 can also be raised independently, so as to allow the flame to find exit from the apparatus in a desired manner.

In case wind should deflect the blaze and cause it to be ineffective at the windward side of the track the swiveled nozzle (shown in Figs. III and IV) can be turned sufficiently upon the turn-table to cause the flame to be directed positively toward the windward side of the track, thus to counteract the effect of the wind. The flexible connections 15, which support the fenders, (not shown in Figs. III and IV, but which it is to be understood from Figs. I and II will be applied,) will allow the fenders to be deflected at the end of the nozzle, so as to carry the flame to the windward side of the track at the point where it issues from the nozzle.
