Abstract

Abstract A cooling fan shroud mounted on an engine vehicle comprises an engine mounting, a radiator mounting and a flexible member made of rubber bellows and connecting the engine mounting and the radiator mounting. The lower portion of the engine mounting is formed in a reverse U-shape, and the lower portion of radiator mounting is formed in a reverse L-shape. The radiator has a support projecting from the lower portion thereof and formed in a U-shape cross section. The reverse L-shaped lower portion of the radiator mounting of the fan shroud is inserted into the U-shaped support projecting from the lower portion of the radiator. The engine has a support formed in a L-shape at the lower portion thereof. The reverse U-shaped lower portion of the engine mounting is inserted onto the L-shaped support of the engine. The upper portions of the engine mounting and radiator mounting of the fan shroud are secured to the engine and the radiator by means of screws.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 157 words
An easily removable cooling fan shroud adapted to be mounted between an engine and a radiator of an engine vehicle, comprising a rigid engine mounting, a rigid radiator mounting, and a flexible member formed as a circular cylindrical bellows normally extending between and connecting said engine mounting and said radiator mounting; wherein said bellows is spaced and separated from free ends of blades of a cooling fan, and said bellows extends from the radiator mounting to substantially a plane of rotation of said cooling fan and said bellows is axially compressible for removal of the cooling fan shroud through a space between said radiator and said cooling fan, lower portions of said engine mounting and said radiator mounting being engageable by slidably releasable U-shaped hook means with supports projecting from said engine and said radiator, upper portions of said engine mounting and said radiator mounting being secureable to said engine and said radiator by means of bolts.
