  • Publication number: 20210129584
    Abstract: The present disclosure provides a bicycle hub that provides improved drive line efficiency and bike-to-rider torque feedback. The drive line efficiencies are due to lower rolling resistance resulting from a novel bearing and sprag clutch configuration, a lightweight design, and immediate torque transfer from the cassette drive to the hub body. The bike-to-rider feedback has been improved as the torque transfer is smooth, predictable, and immediate.

  • Publication number: 20200079152
    Abstract: A sprag clutch based freehub system that has an easily swappable free hub portion is provided. The freehub system uses a cassette driver adapter shaft (also referred herein as “driver”) that is positioned within the hub. The cassette driver adapter shaft (driver) and freehub body have a separable interface. This allows for easy interchanging of freehub bodies by the user while not risking contamination or damage to the hub.

  • Patent number: 10119579
    Abstract: Forward movement of a bicycle results when force is transfer from the chain or belt to a sprocket on a cassette. The cassette is splined to the cassette driver and causes the wheel of the bike to rotate when torque is applied from the cassette to the cassette driver. The cassette driver is typically made of a strong hard material such as steel to withstand the forces in parted thereon by the cassette. The present disclosure provide a hub configuration and method that enables the cassette driver to be made with construction of a lighter weight material such as aluminum yet still withstand the toque applied thereto.

  • Patent number: 5335820
    Abstract: A container arrangement for storage in dispensing a flowable particulate material is provided. The container arrangement comprises a container including a bottom and a wall with a lower dispensing aperture. Arrangements are provided for selectively erecting a slanted dispensing surface operably positioned underneath particulate material received in the container. The dispensing surface, when erected, is positioned above the container bottom and slanted downwardly toward the wall having a lower dispensing aperture therein. Various arrangements for constructing the dispensing surface are provided. A method for dispensing particulate material from a container is also provided.

  • Patent number: 5322098
    Abstract: A transfer system for flowable solids or particulates is described. The transfer system includes an air seal assembly having an upstream side and a downstream side. The air seal assembly is constructed such that an air pressure differential can be maintained between the opposite sides thereof, but particulate material can be transferred through the air seal assembly. The transferring system includes an arrangement for transporting flowable solid material to the upstream side of the air seal assembly, the transfer taking place within a moving airstream at a pressure of less than ambient. Also, the system includes an arrangement for transporting the flowable solid material from the downstream side of the air seal assembly, preferably under gravity influence and ambient pressure. The transfer system includes an articulated arm arrangement on which the air seal assembly is mounted, for convenience.

  • Patent number: 5163786
    Abstract: A cyclone separator (20) for a pneumatic grain conveyor (10) includes a filter assembly (60) mounted in the upper end thereof. The filter assembly (60) includes a cylindrical casing (62) extending into the separator (20) with a screen (70) therein and an adjustable accelerator plate (84) which cleans an adjacent portion of the screen and distributes the collected dust and foreign particles on the remainder of the screen. A second filter assembly (90) is preferably connected between the air outlet of the separator (20) and air inlet of the blower (52) for further dust and foreign particle removal.

  • Patent number: 4433946
    Abstract: The present invention is directed to a folding mechanism for the discharge spout system (12) of a pneumatic conveyor (10). The folding mechanism includes a hinge mechanism (55) having an axis (66) which is skewed with respect to a plane perpendicular to the alignment axis (26) of lower and upper tubes (20, 22). Such a hinge mechanism (55) allows the upper portion of upper tube (22) to pass the lower portion of lower tube (20) while upper tube (22) is pivoting from an operational configuration to a transit configuration. An hydraulic cylinder (68) powers the pivotal movement of upper tube (22). An over-center locking mechanism (84) latches lower and upper tubes (20, 22) in the operational configuration.
