  • Patent number: 4863589
    Abstract: A rigid, elongated member and cover of resilient, abrasive resistant material which provides protection for the rigid elongated member are adapted for positioning under a sizing screen. The cover protects the elongated member from sand falling through the sizing screen, thus reducing the amount of damage that the falling sand may inflict on the elongated member due to abrasion, erosion, etc.
    Type: Grant

  • Patent number: 4832669
    Abstract: A lagging segment having a leading edge in the form of tabs and recesses and a trailing edge in the form of tabs and recesses whereby adjacent segments can be welded to the face of a pulley without damaging elastomer by placing adjacent segments around the face of a pulley with the tabs of the leading edge positioned within the recesses of the trailing edge of adjacent segments and spaced with an air space between the tabs and recesses of adjacent segments such that welds at the ends of the tabs are separated by a heat insulating air space from the recess of the adjacent segment, whereby the spacing between the elastomer portions of adjacent segments is diminished.

  • Patent number: 4787500
    Abstract: A belt scraper assembly for cleaning material from a conveyor belt (2). The scraper assembly (1) includes scraper elements (6) that are slidably secured to a mounting plate (7). An element may be replaced, without stopping the conveyor or the cleaning action, by inserting a new element (6) while pushing an old one out. The scraper element has a curved shape such that the belt continually sharpens the scraping edge (22) as it travels, rather than rounding it.
