Patent number: 5308183Abstract: A timing sprocket is secured to a camshaft by a locking coupling so that before the coupling is tightened the sprocket will free wheel on the shaft for adjustment purposes and yet be firmly supported against tipping under load, and when tightened the sprocket is locked to the camshaft. The sprocket has a bore fitting on the shaft and a counterbore accommodating a longitudinally split locking ring. A taper between the bore and the counterbore matches a taper on the end of the locking ring. A bolt axially threaded into the camshaft end moves the locking ring from the loose condition where the sprocket can rotate on the shaft to a tight condition where the tapers compress the ring against the shaft and clamp the sprocket for rotation with the camshaft.Type: GrantFiled: July 9, 1992Date of Patent: May 3, 1994Assignee: General Motors CorporationInventors: George T.

Patent number: 5236398Abstract: A drive apparatus and method for continuously transmitting power to an axle to rotatingly drive the axle are disclosed. The drive apparatus includes a flexible ratch such as a flexible chain, belt, or cable, and cooperating first and second ratch engaging members for alternatively engaging the flexible ratch to continuously drive an axle. To operate the apparatus, one moves the first and second ratch engaging members in a first direction which causes the first ratch engaging member to engage and drive the flexible ratch which rotatingly drives the axle. One then reverses the ratch engaging members' direction of movement which causes the simultaneous releasing and engaging of the ratch by the first and second ratch engaging members, respectively, which continuously drives the axle.Type: GrantFiled: August 3, 1992Date of Patent: August 17, 1993Assignees: Franklin E.

Patent number: 5224552Abstract: A gardening utility machine having a counter-rotation twin shaft system can perform multiple types of work required for gardening (tilting, soil removal, weeding, racking and shredding of leaves), snow/ice removal and for power de-thatching and mowing of lawn grass. This can be done by exchanging attachments on the counter-rotating twin shafts: if tines are installed on the twin shafts, soil tilling, weeding can be done; if auger blades with or without digging bits are in place instead, the machine can simultaneously till and remove soil or can remove ice/snow, or rack and shred leaves; if the front shaft is installed with a spiked roller and the rear shaft, a shearing reel, then the machine can power de-thatch and mow grass at the same time, and, additional grass clipping mulching ability can be performed if a fan blower equipped with a mulching fan blade and a retractable bedknife is in place.Type: GrantFiled: November 7, 1991Date of Patent: July 6, 1993Inventors: Kai S.
