FIDUCCIA SNOW AND ICE MELTING MACHINE 2 SHEETS'SHEET 2 Filed Nov. 29, 1949 INVENTOR ANTHONY FIDUCCIA W l/ls ATTORNEY Patented Nov. 27, 1951 UNITED STATES PATENT OFFICE 6 Claims.

This invention relates to snow and ice melting machines in general such as disclosed in the United States Patent No. 2,471,733, issued May 31, 1949, to this applicant.

Among the objects of the present invention it is aimed to provide an improved snow and ice melting machine having a main snow and ice receiving container to receive the water from the melted snow in the bottom thereof, a second con tainer in said main container above the level of the water having foraminous converging side walls with a deflector in the middle thereof to intercept the opposing flames and deflect the same into the snow and ice supply as it is introduced, in the interest of a maximum efficiency, that is, to obtain a maximum use of the heat generated by the burners.

It is still another object of the present invention to provide an improved snow and ice melting machine such as disclosed in the United States Patent No. 2,471,733 of this applicant in which the water from the melted snow received in the bottom; of the main container is pumped up through a heater to a supply conduit having a plurality of discharge openings at the upper edge of the container whereby advantage is taken of the heat generated in the conduit and in the heated water discharging therefrom to melt the snow and ice as quickly as it is received and prevent it from accumuTating along the upper edges of the container.

These and other features, capabilities and advantages of the invention will appear from the subjoined detailed description of one specific embodiment thereof illustrated in the accompanying drawings, in which Fig. 1 is a plan view with parts broken away of the improved snow and ice melting machine.

Fig. 2 is a transverse section of the same Fig. 3 is a section on the line 3-3 of Fig. 2.

In the embodiment shown, there is provided a trough l, arcuate in transverse cross section as shown in Fig. 2, with flanges 2 at the upper free ends thereof extending outwardly to rest on the angle iron frame 3, in turn supported on the rectangular frame 4 mounted on the upper web of the channel iron frame 5 constituting part of the chassis of a truck, trailer or the like.

Supported on the upper web of the rear transverse cross piece of the frame 5 and extending upwardly therefrom, there are provided two angle iron uprights B which are secured to the ends of the heat insulated side wall members 1. The front ends of the wall members i in turn are secured to the angle iron uprights 8 extending CJI upwardly from and supported on the upper faces of the upper webs of the frame 5. The upper free ends of the

uprights

6 and 8 in turn may be connected by a rectangular angle iron frame 3 on which rest the outwardly extending flanges ll] of the impervious metal apron H having short inwardly and downwardly flaring extensions l2 at their sides and rear, and a comparatively long inwardly and downwardly flaring extension is at its front end. The extension l2 in turn terminate in vertical extensions I4 having inwardly extending flanges H5 in line with the inwardly extending flange l6 of the extension l3 to form a support for the outwardly extending web of the angle iron frame H at the upper edge of the foraminous extension l8 having inwardly and downwardly flaring side wall members I9 and vertically extending impervious end wall members 29. The side wall members l9 at their lower ends are spaced from one another and have supported on the inner edges thereof the lower diverging ends of the tapering impervious deflector sections 21. The sections 2| as shown are provided with two impervious wall members 22 converging into engagement with one another at their upper'ends.

Extending downwardly and outwardly from the insulated walls'l, there are provided the two outwardly and downwardly flaring supporting frames 23 having an opening below the edge 24, which opening, however, may be covered, as shown at the left side of Fig. 2, by the cover 25 hingedly connected at 26 to the frames 23 at the edges 24 thereof. These covers 25 may be maintained in raised or open position by any suitable means, such as the chain 21, connecting the lower edge of the cover 25 with the angle iron frame 9.

Extending inwardly from the walls I there are provided the brackets 28. From the lower ends of the brackets 28 to the supporting frames 23, in the present instance, there are provided a plurality of rails 29 to form a support for suspendingly securing the

burners

30 and 3|, the burners 30 being disposed as shown in Fig. 1 to direct flames at the foraminous extensions l9, and the burners 3| to direct flames at the two sets of heating coils 32 and 33. The heating coils 32 and 33 are connected at their lower ends to the inner conduit 34 having a drain connection 35 which may be shut off by the valve 36 and also having a connection 31 to the water pump 38 which is connected by the conduit 39 with the inlet cylinder 40 disposed in the trough I below the normal level of the water therein as shown. The shaft of the pump 38 is provided with a For insuring that the level of the water in the,

trough I does not exceed a predetermined height, that shown in Figs. 2 and 3 as anifistsnce, adisfcharge inlet 48 is located at a predetermined altitude above the level of the inlt'cylinder 40" in the trough I connected to. the inner discharge.

conduit 49 which extends out of the. trough I into connection with the conduit 50 which is con-' nected to the. water pump having the discharge conduit 52 connected to-the conduit 53 extending rearwardly and terminating at 54 for connection to a hose or the like to facilitate directing the waterdischalfged to asewer or the like; The shaft of the pump 5| is provided with the sheave 55 drivingly connected by the belt 56 to the driven shaft 43. Consequently when the clutch 45 is actuatedto connect the driven shaft 43 with the motor 44, not only the pump 38 but also the pump 5| will be actuated.

The fuel to the burners-3H and 3| in turn is ll plied under pressure and is fed to theburners 3ll'a'nd 3| by thepump 51, the shaft of which is provided with the sheave 58 which is 'drivingly connected by the belt 59 with the sheave 60 of the motor 44. The pump 5'! in turn is connected to the fuel supply line 6| and with the connection 62' for sup-plying the fuel to the fuel conduits 33 and-64 which preferably are supported on the angle iron rails 65 secured to the chan nel iron frame 5. The conduits 63 and B4 in turn are connected by the flexible extensions 66 to the

burners

30 and 3|.

As-sh'own, whenthe

burners

30 and 3| are not in use, they may be moved up into the position shown at the left hand side of Fig. 2, and the cover 25 lowered-into'the position shown. In turn, when the-burners 3U and-3I are to be used theyare slidably moved to the position desired, secured inplace, and the cover 25anchored in the raised position shown at the right hand side Fig.2. r

-'The deflector- 2| serves to deflect the flames from the burner 30 upwardly intothe mass of snow and ice being received, and to. protect the opposing walls of theflforaminous extension l3. from overheating.

Preferably the trough l as shown is also provided with a drain 6'! controlled by the valve. 68. Similarl the rearwallof the trough l is provided with a sludge cleanoutdoor 69 as shown inv Fig. 2. V

It. is obvious that various changes and modifications may be made to the details of construction withoutdep rtin f m e e er l S r of the invention as set forth in theappended claims.
