Device for reducing icing

DETAILED DESCRIPTION It is therefore, an object of this invention to provide a method of preventing ice build up in exhaust passages in a manner which is easily and inexpensively accomplished and which works effectively.
Towards this end, a passageway is provided with a tubular liner, which has a generally smooth inner surface and an outer surface which is spaced away from the interior of the passage by a number of spacing elements.
The spacing elements extend outwardly to locate the liner within the passage, and either end of the liner is sealed to the passage by a ridge.
The liner is made from a flexible material, so that when the high pressure exhaust air passes through it, the liner flexes, thereby causing any ice which may form to flake off and be carried on through the passage and out the ultimate exhaust.
These and other objects and advantages of the invention will appear more fully from the following description made in conjunction with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several views.
