Publication number: 20220152781Abstract: Systems and methods for grinding are provided. In one embodiment, systems and methods for grinding are provided having a floating or self-adjusting dust collector or means. This allows the dust collector or guard to adjust its position relative its support member to allow for uninterrupted grinding operations as the grinding element(s) wear away. Biasing and guiding assemblies or means are provided that allow the dust collector/guard to be guided closer to its support structure to compensate for the grinding elements become smaller as they wear away during the grinding operation.Type: ApplicationFiled: November 16, 2020Publication date: May 19, 2022Applicant: Diamond Products LimitedInventors: Miroslav Pavlovic, Timothy M. Obrzut, Jeffrey A. Gray

Patent number: 10066713Abstract: Inventive embodiments are directed to components, subassemblies, systems, and/or methods for continuously variable transmissions (CVT). In one embodiment, a main axle is adapted to receive a carrier assembly to facilitate the support of components in a CVT. In another embodiment, a carrier includes a stator support member and a stator interfacial member. In some embodiments, the stator interfacial member is configured to interact with planet subassemblies of a CVT. Various inventive planet subassemblies and idler assemblies can be used to facilitate shifting the ratio of a CVT. In some embodiments, the planet subassemblies include legs configured to have a sliding interface with a carrier assembly. Embodiments of a hub shell, a hub cover are adapted to house components of a CVT and, in some embodiments, to cooperate with other components of the CVT to support operation and/or functionality of the CVT. Among other things, shift control interfaces and braking features for a CVT are disclosed.Type: GrantFiled: December 21, 2016Date of Patent: September 4, 2018Assignee: Fallbrook Intellectual Property Company LLCInventors: Jon M. Nichols, Matthew P. Simister, Daniel J. Dawe, Charles B. Lohr, Timothy M. Obrzut

Patent number: 9480196Abstract: A vertical tine tiller that includes a chassis, an engine attached to the chassis, a handle assembly extending from the chassis to allow an operator to control the tiller, and at least two vertically oriented tine assemblies. Each of the tine assemblies include a plurality of tines attached to a plate, wherein the tine assemblies are rotatable about a vertical axis such that the tines of each tine assembly provide a grinding path and adjacent tine assemblies have at least partially overlapping grinding paths. The tines are removably connected to the plate.Type: GrantFiled: May 23, 2013Date of Patent: November 1, 2016Assignee: MTD PRODUCTS INCInventors: Timothy M. Obrzut, Paul A.
