Abstract
1,183,529. Chain tensioners. JOH. WINKLHOFER & SOHNE. 16 Aug., 1968 [18 Aug., 1967], No. 39377/68. Heading F2Q. A chain tensioner comprises a head 1, 4 spring-urged into slidable contact with a chain to be tensioned, and a ratchet device between the head and a fixed point, comprising a plate 5 having a slot 6 engaged by a pin 7, the slot having a smooth wall 8 against which the pin 7 rides as the head moves in a direction to tension the chain, and a toothed wall 9 which is engaged by the pin 7 when the head is urged in a direction allowing the chain to slacken, to limit said slackening movement. In Figs. 1, 2, the head 1, 4 includes a hollow cylindrical base slidable in a housing 2 and containing a compression spring 3 which urges the head outwardly of the housing. The head carries the pin 7 and the plate 5 is pivoted at 10 to the housing, a Belleville spring 11 providing friction to resist pivoting of the plate 5. In Fig. 10, a leaf spring 62 secured to the housing 2 at 60, 61, frictionally engages the plate 5, which in this case is pivoted to the head 1, the pin 7 being mounted on the housing 2. In Figs. 8, 9 (not shown), the plate (5) is slidingly mounted on the housing (2) for movement transversely of the direction of movement of the head (1, 4) and is engaged by a friction leaf spring (15). In Fig. 11, the plate 5 and head 1, 4 are both pivoted to the housing 2, a plunger (111) (Fig. 13, not shown) acting on the head. In Fig. 14, the head 1, 4 has a fixed pivot 140 and a tension spring 3 acts on a lever 141 forming an extension of the part 4. The plate 5 has a fixed pivot 10.
