Abstract

861,741. Chain and belt tensioning. PERRY CHAIN CO. Ltd. June 23, 1959 [Aug. 12, 1958], No. 25820/58. Class 80 (1). To prevent snatch or jerking in a chain or belt drive on over-run, when the slack run becomes tensioned and the tensioned run becomes slack, and vice versa when the drive is taken up again, two spring-biased plungers 13 acting directly or through pivoted members on slippers 14 or on sprockets co-operate with the two runs of the chain, respectively on opposite sides of a sprocket, and reciprocate in hydraulie-fluid-filled cylinders connected with one another by a passage or an orifice 9, so that, in use, the two plungers move together in a controlled manner so as they effect a smooth change in the tensions of the two runs of the chain whenever a reversal or over-run of the drive occurs. The cylinders are kept filled with fluid from a reservoir 6 through clack-valves 20 in the plunger, as described in Specification 810,274, or a cylinder and plunger construction as described in Specification 788,500. In Fig. 4, not shown, the cylinders are offset one above the other and are joined by a bleed passage through the dividing wall. In Fig. 5, not shown, the tensioning units are positioned outside the chain runs and the cylinders are connected by a pipe of suitable bore.
