SNOW-MELTING APPARATUS.

Specification of Letters Patent.

Patented May 7, 1907.

Application filed July 2, 1906. Serial No 324,302.

To all whom it may concern:

Be it known that 1, Louis T. FRIeoN, a subject of the King of Great Britain, residing at the city and district of Montreal, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Snow-Melting Apparatus; and I do hereby declare that the following is a-full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to snow melting apparatus the object of my invention is to provide an apparatus adapted to melt snow by the direct action of a hydrocarbon burner, and to prevent the melted snow from congealing by the application of indirect heat; a further object is to provide an apparatus of the character described, with a grate which will quickly conduct the melted snow away, so that the apparatus is not cooled by the melted snow; a further object is to provide an apparatus of few parts, and which may be easily separated and cleaned; and, my invention consists of the construction, combination and arrangement of parts, as hereinafter more fully illustrated, described and claimed.

In the accompanying drawings, forming part of this application, I have illustrated one form of embodiment of my invention, in

which drawings similar reference characters designate corresponding parts, and in which:

Figure 1 is a perspective, the outer walls of the casing being partly broken away to show the interior construction Fig. 2 is a transverse vertical section through the apparatus; and Fig. 3 is a fragmentary detail in end elevation, showing the opening and its closure, through which opening may be inserted the nozzle of a hose.

Referring to the drawings, 1 designates a rectangular base frame, adapted to support a bottom 2. Carried by the base frame 1 are standards 3, adapted to support the arched frame members 4. Carried by the standards 3 are cross braces 5, and carried by the arched members 4 are upper cross braces 6. Also carried by the standards 3 are longitudinal frame members 7, and carried by the arched end frame members 4 are longitudinal braces 8, and a central longitudinal brace 8 Supported by the cross braces 6, and extending longitudinally of the apparatus, is a strap 9, to which are connected the tie braces 10, secured to and supporting the downwardly arched deflector plate 11, which is also supported by the arched end members 4, and the strap 9.

Carried by the plate 11 is a plurality of funnel-shaped members 12 connected with the vertical pipes 13, and having disposed therein burner plates '14. Disposed above the burner plates are nozzles 15, connected to the pipes 16, which extend to a suitable source of oil supply. The vertical pipes 18 connect with the pipe 17, which in turn is connected to a suitable source of compressed air. The pipe 16 has thereonvalves 18 adapted to control the flow of oil to the burner, and the pipe 17 has thereon suitable valves 19 to control the supply of compressed air. By this construction, flame from a suitable hydrocarbon burner may be directed downward and outward by the funnel-shaped members 12. The portion of the apparatus above the curved deflector plate 11 is covered by the removable plates or'roof 20, disposed on the braces 8 and 8. The space between the braces 7 and 8 on the opposite sides of the apparatus is covered by the members 21, se-

cured by means of the hinges 22 to the braces 7. Extending inwardly and downwardly from the braces 7 on each side of the apparatus are removable snow deflecting plates 23, the lower ends of which extend over the outer sides of the grate hereinafter described.

Disposed below the lower ends of the deflecting plates 23, and extending longitudinally of the apparatus, is a segmental removable grate 24, provided with a flange 25 at its ends and sides, and also provided with vertical openings 26 adjacent its outer side edges. The flange 25 is further provided on the sides with the horizontal openings 27. By this construction, the water resulting from the melting snow will be readily conveyed from the grate.

Disposed with one of their edges beneath the outer edges of the grate 24, on either side of the grate, are inclined troughs 28, extending longitudinally of the apparatus and removably disposed on arms 28 These troughs extend through the wall at one end of the apparatus, and terminate in projecting spouts 29, whereby the melted snow may be conducted from the apparatus.

Disposed beneath the grate 24 is a plurality of burners 30, staggered with relation to the ICC , zle, whereby water may be projected into the apparatus, and the whole apparatus cleaned of the matter left behind the melted snow.

The end opposite the discharge pipes 29 is closed by the lower wall 36 and the upper wall 37. The side walls are formed by the upper and lower side members 38, connected to the framework by means of the hinges 39, and provided. with handles 40, by means of which they may be easily swung on their hinges. The end walls of the apparatus have therein openings covered by the doors 41, connected to the framework by means of the hinges 42, and provided with a handle 43. The object of the removable top sections and the hinged side and end doors, is to permit ready access to the interior of the apparatus for the purpose of cleaning the same.

In the operation of the apparatus, it will be understood that the snow to be melted is passed through. the opening, normally covered by the door 21. The snow is then conducted by the plates 28 to a position over the grate 24, where it is struck by the direct flame from the burner in the funnels 12. At the same time the lower portion of thebody of snow so introduced into the apparatus is being melted by the indirect heat from the burners 30. The grate 24 being heated, the melted snow runs off the curved floor of the grate before it can again congeal. The

- radiated heat in the apparatus is sufficient to keep the snow melted, so that it is only water which runs through the troughs 28. It will be understood that the apparatus will be mounted upon wheels, runners or similar constructions, so that the same may be easily transported from place to place.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a snow melting apparatus, the combination comprising a frame, closures hinged on the sides of the frame, hinged closures for a portion of the top of the frame, removable closures for the remainder of the top of the frame, solid closures for a portion of the ends of the frame, hinged closures for the remainder of the ends of the frame, means for subjecting snow within the apparatus to the direct and the indirect action of flame, and means for conducting melted snow from the frame.

2. In a snow melting apparatus, the combination comprising a receptacle, a segmental grate having a flange and provided with vertical openings and with horizontal openings in the flange, burners disposed above and below the grate, troughs disposed adj acent the edges of the grate and projecting from the receptacle, and means for permit ting the insertion of a nozzle adjacent the ends of the troughs.

In a snow melting apparatus, the combination comprising a receptacle, a grate in the receptacle, burners above and below the grate, funnel-shaped flame deflectors around the burners, troughs disposed adjacent the edges of the grate and projecting from the receptacle, and means for permitting the insertion of a nozzle adjacent the ends of the troughs.

4. In a snow melting apparatus, the combination comprising a receptacle, a removable grate disposed Within the receptacle, snow deflector plates extending to the grate, inclined troughs arranged adjacent the edges of the grate, said receptacle being provided with openings adjacent the upper ends of the troughs, hinged closures for the openings, burners above and below the grate, and a downwardly arched heat deflector plate disposed above the grate.

5. In a snow melting apparatus, the com bination comprising a receptacle, a downwardly arched heat deflector plate carried in the receptacle, a segmental grate disposed below the deflector plate and provided with a flange and having drainage openings in the flange and in the grate. a plurality of hydrocarbon burners above the grate, a plurality of hydrocarbon burners below the grate, oil and compressed air supply pipes connected to the burners, an'dwater conducting members disposed adjacent the edges of the grate beneath the openings therein and extending outside of the receptacle.

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

LOUIS T. FRIGON.
