SNOW-MELT'ING MACHINE.

SPECIFICATION forming part of Letters Patent No. 541,709, dated June 25, 1 895.v

Application filed February 19, 1895. Serial No. 538,933. tNo model.)

.Snow-Melting Machine, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved snow melting vmachine, more especially designed to be drawn through the streets of cities and like places, and arranged to quickly melt the snow.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in whichsimilar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement on the line l l of Fig. 2. Fig. 2 a sectional plan viewof the same on the line is 2 2 of Fig. 1. Fig. 3 isa plan view of the fur nace with the cover removed and one of thek grates partlywithdrawn, and Fig. 4 is a sectional side elevation of the same in a different position. p

The improved snow melting machine is provided with a wheeled vehicle A, adapted to bedrawn or driven through the streets or other places in which the snow is to be melted. This vehicleAis provided in its bottom between the front and rear wheels with a chamber B, open at the bottom and extending close to the sur` face of the street, as indicated in Fig. l. In

` the front end of the chamberB is arranged a revoluble brush C for sweeping the snow from the street, into the said chamber B. This revoluble brush C is connected by a belt D with a pulley on an engine E, supported on the vehicle A, and driven by steam from a boiler set in the vehicle, or by other suitable motive power. In the top of the chamber B is arranged a down-draft furnace F, provided with a re box F', arranged transversely in the chamber B and journaled at its closed ends by trunnions F2 in the sides of the vehicle A. A slidab-le and removable grate F3 is arranged in the bottom of the said tire box F', and a similar grate F4 is arranged in the top thereof, so that the fire box, when turned upside down, has a grate' both on the top and l on the bottom; andtbetween the grates is con tained the coal Or other fuel to be burned.

In order to hold the fire box F in proper position, as shown in'Fig. l, I provide va suitable fastening device, preferably in the form of a transverse rod G, adapted to be passed through staples G in the Y vehicle A, and through a staple F5 in the side o f the fire box F. When the rod G is withdrawn, the box can be conveniently turned, to bring the lowermost grate tothe top andthe upper grate to the bottom, as will be readily understood by reference to Fig. 4.

In order to introduce the fuel, the uppermost grate is pulled out, as indicated in Fig. 3, so as to permit of charging the already burning fuel with a fresh supply of coal. The top of the fire box F above the uppermost grate is adapted to be closed by a cover F6, connected at one end by a exible pipe H with a blower I, driven by a belt J from the engine E.

Now, it will be seen thatwheu the engine is in motion, the blower I is actuated, and forces air through the pipe H and cover F6, into and through the fire box F in a downward direction, so that proper combustion of the fuel in the lire box is obtained, and at the same time the heat is forced through the lowermost grate F3 into the chamber Bin contact with the snow thrown into the chamber by the brush C. The snow is thus subjected to a high degree of heat and instantly melted,

to then run into the gutter or to be sweptinto the same by following brushes if necessary.

A chimney B in the rear end of the chamber B, permits the escape 0f gases from the I claim as new and desire to secure by Letters Patent- ICO adapted to supply air thereto, substantially as set forth.

3. The combination of a heating chamber having a transverse shaft, a furnace rotatably mounted in the heating chamber and provided with longitudinally movable grates at its opposite sides and having means for lockin g it to said transverse shaft when set to the required position, a cover plate located in the heating chamber and adapted to close one side of the furnace, a blower, and a pipe connectingthe blower with the cover of the heating chamber, substantially as set forth.
