To all whom it may cancem: v

Be it known that I, BARNEY GOLDMAN, a

citizen ofthe United States, residing atv New York, in the county of New York and State of New York, have invented new and useful Im rovements in Snow-Melting paratusno which the following is a speci cation.

This invention relates essentiall to an in the direction of travel to direct the flame toward a bank of snow.

Another object of the invention is to provide a scooping device operated by the propelled snow melting truck, whereby the soft snow and refuse is elevated from the ground into a wagon trailer connected to the snow melting device.

Another object of the invention is to provide a motor conveniently mounted on the truck frame adjacent to the combustible tank for propelling the truck.

The invention resides in the novel combinations hereinafter described and claimed, reference being made to the accompanying drawing in which:

Figure 1 represents a sectional side elevation of an apparatus embodying this invention.

Fig. 2 is an inverted plan view of the snow melting truck.

Fig. 3 is a transverse section taken along the line 3 3 of Fig. 1.

. In thel drawing is shown a truck including front and rear wheels 5 each having an axle 6 secured by means of hangers 7 to the platform or frame 8 of thetruck. On the plat formis secured a motor 9 driven by gasolene or other fuel. The motor has a belt and pulley connectionv 10 with a pulle 11 on the rear axle for propelling the vehicle. On the platform alongside of the motor is mounted a tank 12 for generating carbid. A coil 13 is arranged below the platform and it is cennecte to the tank by means of a feed plpe 14 having a-'valve 15 for controlling the flow of' the gas from the tank to the coll.

From the bottom of the coil project a series of nozzles 16 having inclined or an ular portions to ypoint in a direction in whic the vehicle is traveling. Arranged insideof the said coil is another coil section 17, best seen in Fig. 2. The latter is connected to the main pipe b means of a branch pipe 18 as indicated in y to govern the flow of as to the inner coil. The inner coil has nozz es similar to nozzles on the outer coil and pointing in the direction in which the vehicle is moving.

It will be understood, from the foregoin that the outer and inner coils are indepen ent of each other in view of the fact that ig. 3, provided with a valve 19 when the valve 19 of the branch pipe is shut,

it will eliminate the inner coil without interfering with the outer coil. The valve controls the volume of gas from the tank to both coils. This arrangement permits one coil to be put out of action when desired, while the other coil can remain in action. Any number of the coil sections and nozzles can be provided and as shown the flame at the end of a nozzle is ydirected toward the pile of snow while the truck is moving forward.

In order to prevent any heat from the nozzles striking the platform and the wheels of the truck, a sheet of asbestos 20 is arranged between the platform and the coils.

vThe sheet has side members 21 extending downwardly to prevent the flame from injuring the wheels and other bearings. The axles can also be covered with a non-conductor of heat 22 where they are exposed to the flame.

At the back of the snow melting truck is positioned a vertical carrier consisting of an endless belt or chain 23 engaging an upper roller or sprocket 24 and a lower roller or sprocket 25. The sprocket 25 is rotated in the proper direction by a cross belt 26 in engagement with a drive pulley 27 mounted on the rear axle of the truck. The endless belt has secured to it a series of buckets 28 made to scroop up any soft snow or dirt left from the melting snow or ice, elevate it and drop it into the body of a wagon 29 rolling behlnd the carrier. vThe frame 30 of the carrier is fastened to the forward part of the wagon and the wagon is hooked by removable bars 31 to the truck. A brush 3.3 to sweep up the remainder of the dirt 1s mounted below the body and it is connected to the rear wheel by a belt 34 to rotate it when the wagon is moving. When it is desired to use the melting apparatus without the trailer, the latter can be removed by unliookin the bars. v

it will be understood that the truck ma be attached or hooked to the front of a tro ley car, railroad train or automobile, and various changes may be made in the position of the heat generating means or driving mechanism Without departing from the principle of this invention.

l claim:

l.. A snow melting apparatus comprising a truck having a frame, means for propelling the truck, a fuel tank mounted on the frame, a plurality of coils connected to the tank secured to the frame, each coil being independent of the other, a main pipe connecting the coils with the tank, a branch pipe leading from the main pipe to coil, a valve on the main ipe for controlling the volume of fuel admitted to each coil, a valve controlling the flow of fuel from the main pipe to the branch pipe, and a series of burner tubes projecting downwardly from the coils.

2. A snow melting apparatus comprising a truck having a frame, a fuel generator mounted on the frame, a plurality of coils connected to the generator arranged under the frame, each coil being independent of the other, means for controlling the volume `of fuel admitted to each coil, a valve for shutting oil one of the coils, and a series of nozzles projecting downwardly from the coils with angular portions to point in a direction of the travel of the truck.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

SAMUEL Lewis, WILLIAM Minnen.
