from the fourth wall 16 the thickness of the body member 23 corresponds to the spacing between the side walls 15 and 16 at the bottom of the body member and the thickness diminishes from the base 21 toward the top where the body member 23 terminates in a blade tip 27 when handling wet materials which tend to adhere to the conveyor belt there is a tendency for the wet material as it is scraped from the belt surface to adhere to the tip of the blade both on the outer face and along the under surface depending on the character of the wet material the material adhering to the blade may tend to build up on the under surface of the blade adjacent the scraping tip when this occurs the accumulation of the material on the under surface of the blade may tend to cause the scraping edge to disengage the surface of the belt or may serve as a dam or block against the bias of the blade holder 22 forcing the scraping edge of the blade against the belt with the foregoing mind the present invention provides an improved scraper blade which overcomes the problems described above specifically the improved scraper blade of the present invention is designed to replace the conventional blade 14 shown in fig1 fig2.
