Abstract
1422727 Belt or chain tensioning devices G WINKLHOFER and O WINKLHOFER [trading as JOH WINKLHOFER & SOHNE] 14 March 1973 [16 March 1972] 12380/73 Heading F2Q A belt or chain tensioner comprises a tensioning head 1 carried by a piston 2 which is displaceable in a cylinder 3, a spiral cam 4 and cam follower 5 between the piston and cylinder, a coil spring 6 which engages the piston 2 and urges it out of the cylinder 3, a disengageable stop ratchet 7, 8 disposed between the cylinder and the cam 4 and cam follower 5, and a retraction and latch device consisting of a pin 9 extending through the base of the cylinder and a spring disc 10, provided with opposed arms, mounted on the pin 9. The arms of the disc 10 are adapted to co-operate with rivet heads 12 in order to form a latch. When the latch is released, the piston can be pushed out out of the cylinder unhindered. Movement of the piston into the cylinder is restricted by the stop ratchet 7, 8 except when the pin 9 is moved axially to disengage the ratchet 7, 8. In a modification, a spiral cam groove, which may contain steps, in a sleeve 13, Fig. 3, is engaged by a pin 14 integral with the piston 2. The end of the cam groove is formed with an eye 20, Fig. 4, for latching purposes. Alternatively the latching means comprises a spring hook on the tensioning head which is adapted to engage a complementary hook on the cylinder, or a spring on the cylinder which is adapted to engage a retaining surface on the head. In other embodiments, spring-loaded locking balls are used. In a further modification a sleeve 30, Fig. 10, has extensions 28 which are adapted to engage spiral threads 29 located in a piston 2<SP>1</SP>.
