Snow melting device

Abstract

A hand-propelled self-contained movable electrical snow-melting device which has a frame on which is mounted an enclosure formed by a bottom heat-conductive plate and an upper cover. An electrical heater is positioned within the enclosure and a portable electrical power supply is supported by the device and is connected to the heater.

I claim:  
     
         1 . An electrical snow-melting device comprising a frame supporting an enclosure comprising a bottom heat-conductive plate and an upper cover; an electrical heating means being positioned within said enclosure; said device including a portable electrical power supply means for actuating said heating means.  
     
     
         2 .  Claim 1  wherein said frame is mounted on a member of a support group consisting of a support set of at least one wheel, a support set of at least one runner and a support set of at least one wheel and at least one runner.  
     
     
         3 .  Claim 1  wherein said bottom plate is made of copper.  
     
     
         4 .  Claim 1  wherein said upper cover is made of aluminum  
     
     
         5 .  Claim 4  wherein said cover is spherically shaped  
     
     
         6 .  Claim 1  wherein said heating means is an electrical coil.  
     
     
         7 .  Claim 1  wherein said power means is a battery means  
     
     
         8 .  Claim 7  wherein said battery means is rechargeable.  
     
     
         9 .  Claim 1  wherein said frame is connected to a handle  
     
     
         10 .  Claim 1  wherein said frame is mounted on a first support set comprising at least one front wheel and a second support set comprising at least one rear wheel; at least one horizontal bar connecting said two sets.  
     
     
         11 .  Claim 10  wherein said frame is connected to a handle which has a hand grip for moving said device and a pair of outwardly curved arms terminating in the central area of said second set.  
     
     
         12 .  Claim 11  wherein a battery means is mounted on said handle and has wires extending from said battery means through said arms to said heating means.  
     
     
         13 .  Claim 12  wherein said battery means is rechargeable  
     
     
         14 . A hand-propelled self-contained electrical snow-melting device comprising a frame mounted on a first support set comprising at least one front wheel and a second support set comprising at least one rear wheel; said frame having at least one horizontal bar connecting said sets; said frame supporting an enclosure comprising a bottom heat-conductive plate and an upper cover; an electrical heating means being positioned within said enclosure; said device including a completely portable electrical power supply means for actuating said heating means.  
     
     
         15 .  Claim 14  wherein said said frame is connected to a handle which has a hand grip for moving said device and a pair of outwardly curved arms terminating in the central area of said second set.  
     
     
         16 .  Claim 15  wherein said power supply means is a battery means mounted on said handle; said battery means having wires extending through said arms to said heating means  
     
     
         17 .  Claim 14  wherein said bottom heat-conductive plate is made of copper and said upper cover is made of aluminum.  
     
     
         18 .  Claim 17 , wherein said upper cover is spherically shaped.  
     
     
         19 .  Claim 16 , wherein said battery means is rechargeable.
