| 81 | Debris resistant bearing system and method | US12781655 | 2010-05-17 | US08215844B1 | 2012-07-10 | Philip M. Hoyt |
| A system and method are disclosed for protecting bearings operating in dirty environments. The system may include a reservoir of lubricant, a bearing, and a regulator. The bearing may border on both the dirty environment and the reservoir. Accordingly, the bearing may be exposed to the solid particles carried by the fluid within the environment, as well as the lubricant of the reservoir. The regulator may ensure that the pressure within the reservoir is greater than the pressure of the dirty environment. Due to the higher pressure within the reservoir, the bearing may be preferentially filled with lubricant rather than dirty fluid from the environment. | ||||||

| The problem of damage sustained to a traction device and the extendable traction elements thereof due to tire-roadway interaction forces exerted on the traction elements while extended over the tire tread area is solved by resiliently coupling a traction assembly within a tire rim to permit movement and repositioning of the traction assembly relative to the rim and biasing back to the original position. Preferably the traction assembly is mounted to a traction hub through a resilient coupling, and with the traction hub permitted to rotate relative to the rim. Also preferably, the invention provides for full retraction of the curved traction elements. This inventive device delivers increased traction in slippery conditions while protecting the traction device and surrounding mechanics from damage due to the impact of various roadway forces, and the device is effectively stowed within the rim when not in use. | ||||||

| Embodiments of the present invention provide a wheel for an agricultural irrigation system that permits movement of the irrigation system through muddy, slippery fields without leaving significant wheel ruts in the field and without requiring regular tire maintenance. In a first aspect, the present invention provides a regular polygonal wheel for use in an agricultural irrigation system. The wheel can include a central hub defining a central bore that is configured to mate with a wheel stud of the agricultural irrigation system. The wheel can include an outer circumferential portion that is configured to contact a surface on which the wheel is rolling. The circumferential portion can include a plurality of flat rectangular plates connected together to form a regular polygon. Each plate can have inner and outer opposed major surfaces, along with first and second opposed edges and third and fourth opposed edges. Each plate can be oriented such that its inner and outer major surfaces are perpendicular to the wheel's radius. Each plate can have its first edge connected to the second edge of another of the plurality of plates to form an interior angle. Each plate can have the first edge of yet another of the plurality of plates connected to its second edge to form the interior angle. The interior angle multiplied by the number of plates equals 360 degrees. The wheel can include a plurality of spokes connecting the central hub and the outer circumferential portion. | ||||||

| An all-terrain bicycle is comprised of a tubular frame defined by a main frame section and a front fork and a pair of rear forks, to which is removably secured a front and a rear wheel. The wheels are formed of plastics material and define a hub, a circular outer molded solid tire, and an intermediate connecting framework. The outer molded solid tire is a one-piece tire defining, when viewed in transverse cross-section, a central projecting dome merging into opposed tapered wings which are recessed from the top of the dome. An integrally molded connecting formation is provided under the dome to secure to a rim of the connecting framework. The dome defines a circumferential central rib around the outer molded tire for the displacement of the bicycle on a hard surface with the wings spaced from the hard surface. The wings constitute a wide tire support surface, together with the central rib, for the displacement of the bicycle on soft surfaces such as sand, grass, etc. | ||||||

| A traction aid for a roadwheel of a vehicle of the type arranged to be laid on the ground in engagement with the roadwheel to give traction to the latter. A traction aid of the above type provided with claws constructed and arranged to engage tires of any widths to obtain firm initial engagement with the roadwheel and positive initial traction of the latter. The claws are further arranged to positively engage into cavities between the treads of a tire by a lever action on the traction aid. The traction aid according to the invention further includes traction cleats arranged to bite into the ground and a single U-shape frame having opposite free ends bent to form the claws. The overall width of the traction aid at the level of the claws is less than the width of the major portion of the device and is at the most about equal to the width of the tire tread. Thus, it is easy to insert the claws into engagement with the tire tread cavities, even if the rut in which the tire is located is not any wider than the tire, while good stability of the device is obtained when the tire rides on the same, due to the substantial transverse spacing between the traction cleats.
