Abstract

1,000,546. Belt gearing; levers. TARPEN ENGINEERING CO. Ltd. Aug. 24, 1962 [May 17, 1962], No. 19027/62. Headings F2K and F2Q. In a device for automatically releasing the tension of a belt on overload, one of the pulleys, e.g. a drive pulley or a jockey pulley, is rotatably mounted in a boss 5 on a lever 4 which is biased about a fixed pivot 7, to tension the belt, by a leaf spring 11 engaging a roller 18 on the lever, the spring 11 being bent at 17 so that on overload the roller 18 snaps over the bend to disconnect the drive, the lever then engaging a stop 19. The roller 18 is mounted on an adjustable tail 6 of the lever 4, the tail comprising a plate pivoted on the lever (e.g. at 7) and secured by a screw 10 engaging one of three holes 9. The spring 11 is mounted on a fixed stud 13 through an eccentric bush integral with a body 16, rotation of which adjusts the spring position. Belt tension is thus coarsely adjusted by the screw 10 and finely adjusted by the body 16. According to the Provisional Specification, the device is applicable to chain-and sprocket drives.
