Abstract: An automatic brake release valve in the form of a normally open pressure relief venting structure for air operated vehicular brakes and the like, wherein atmospheric air is vented into the closed brake system intermediate the air brake actuating valves and the brake chambers actuated thereby. This venting valve structure relieves any pressure build-up which occurs as a result of brake valve leakage, since any increase in pressure in this part of the system closes the exhaust valves and actuates the brakes. So that normal brake function is maintained, the venting valve structure closes on a predetermined pressure rise. Thus, when the brakes of the vehicle are applied, a limited amount of air will escape from the system, until the predetermined valve closing pressure is reached, and during this air escape period, water condensate is exhausted from the system automatically, while providing maximum brake efficiency.

Abstract: This invention is directed to and for use on mobile homes. The primary function of the structure is reduce and minimize roof rumble when the mobile home is exposed to natures turbulant forces. The structure consists of a pair of generally L shaped brackets, one bracket disposed at the intersection of each of the sidewalls with the roof. A connecting member is interposed between each of the L shaped brackets and fitted with means for maintaining said connecting member in substantial contact with the roof of the said mobile home, thus reducing and minimizing roof displacement which causes the rumble.
