Abstract
Abstract An improved ice and snow melting system employing motor vehicle hot exhaust gases includes a stub pipe for bolt-on clamping to the rear of a motor vehicle exhaust pipe in parallel-spaced realtion, in forward direction the stub pipe divides in a "Y" shaped configuration; from each arm of the "Y" a flexible tube leads forward and outward to a portion adjustable to heat a vehicle drive wheel and road surface traction area; for valving hot gases from the motor vehicle exhaust into the system a flexible tube is applied in "U" shape and through frictional fit to connect the rear of the vehicle exhaust pipe with the stub-tube; when not in use the flexible tube may be removed and stored in the trunk of the motor vehicle.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
184 words
In a system for melting snow and ice by directing hot gas from a rearwardly extending motorvehicle exhaust pipe to the traction surfaces at the drive wheels through a conduit system having a rear part with a rear end, a middle part and a front part with distribution means, the improvement comprising: means for adjustably mounting the middle part of the conduit system to a motor vehicle, means for clamping the rear part of the conduit system adjacent the rear end of said exhaust pipe, means for connecting the rear of said exhaust pipe disconnectably to the rear part of the conduit system for ducting the hot gases therethrough, the distribution means including means for adjustably directing the hot gases from the front part of said conduit system to said traction surfaces, said means for connecting comprising a quick attach/detach tubing having first and second ends; the first end having provision for resilient friction-fit over the rear end of a said exhaust pipe, and the second end having provision for resilient friction-fit over the rear end of said rear part of the conduit system.
Claim 2
Dependent Claim
184 words
In a system for melting snow and ice by directing hot gas from a rearwardly extending motorvehicle exhaust pipe to the traction surfaces at the drive wheels through a conduit system having a rear part with a rear end, a middle part and a front part with distribution means, the improvement comprising: means for adjustably mounting the middle part of the conduit system to a motor vehicle, means for clamping the rear part of the conduit system adjacent the rear end of said exhaust pipe, means for connecting the rear of said exhaust pipe disconnectably to the rear part of the conduit system for ducting the hot gases therethrough, the distribution means including means for adjustably directing the hot gases from the front part of said conduit system to said traction surfaces, said means for connecting comprising a quick attach/detach tubing having first and second ends; the first end having provision for resilient friction-fit over the rear end of a said exhaust pipe, and the second end having provision for resilient friction-fit over the rear end of said rear part of the conduit system.
Claim 3
Dependent Claim
47 words
In a system as recited in claim 1, the means for clamping having provision for holding said rear part of the conduit system to the rear end of said exhaust pipe in parallel-spaced relation thereto, and the quick attach/detach tubing being in "U" shape during said connecting.
Claim 4
Dependent Claim
40 words
In a system as recited in claim 2, said quick attach/detach tubing being flexible for adjusting to center distance between said rear end of said rear part of the conduit system and the rear end of a said exhaust pipe.
Claim 5
Dependent Claim
29 words
In a system as recited in claim 3, the rear end of said rear part having a rigid stub-tube for receiving the second end of the quick attach/detach tubing.
Claim 6
Dependent Claim
21 words
In a system as recited in claim 4, the rigid stub tube being integral with a part of the clamping means.
Claim 7
Dependent Claim
51 words
In a system as recited in claim 3, the rear end of said rear part of the conduit system having a diameter the same as a diameter of the rear end of a said exhaust pipe, and the quick attach/detach tubing first and second ends having a diameter to fit same.
Claim 8
Dependent Claim
19 words
In a system as recited in claim 6, the quick attach/detach tubing being made of a heat-resistant elastomeric compound.
Claim 9
Dependent Claim
22 words
In a system as recited in claim 2, the forward part and middle part of the conduit being of flexible metallic tubing.
Claim 10
Dependent Claim
46 words
In a system as recited in claim 1, said means for adjustably directing including plural outlets for respective drive wheels, and means for diverting hot gas from one said outlet to another comprising a cup proportioned for retention by tight friction fit over a said outlet.
