Abstract: 1,153,433. Endless conveyers. AJEM LABORATORIES Inc. 24 June, 1966 [8 July, 1965], No. 28546/66. Heading B8A. [Also in Division B1] An endless conveyer belt 10 is formed with guide rails 13 which are adapted to engage guide pulleys 15b, 15c, 15d thereby constraining the belt to a pre-determined path. The rails 13 are mounted on edging strips 14. The pulleys may be adjusted in a direction normal to the plane of the belt by screws (19), (Fig. 2, not shown); they may also be resiliently mounted. The rails may be of triangular, square, trapezoidal or half-round cross-section, the crosssection of the pulley rim conforming to this shape in each case. As applied to a mesh screen belt for a filtration unit (Fig. 8, not shown), (see Division B1) one guide pulley (72) is located near a drive drum (71) which bears the reaction of the pulleys (72). Another pulley (74) bears on a bearing surface (76).
