Including Threaded Or Grooved Bearing Surface Patents (Class 267/264)
  • Patent number: 9485903
    Abstract: A system comprising an air seeder assembly has a base mount with base ears including a first pair of base bores and defining a channel therebetween with a channel width. The assembly comprising a seed boot removably mountable on the base mount, and having a pair of boot ears with a first pair of boot bores. A seed boot stabilizer is mountable on the seed boot and the base mount and positionable in the channel between the seed boot and the base mount. The boot stabilizer has a primary portion with a first stabilizer bore alignable with the first pair of base bores in the base ears. A fastener structure may extending through the pair of base bores of the base ears, the pair of boot bores of the boot ears and the stabilizer bore to fasten the stabilizer to the seed boot and the base mount.

  • Patent number: 9073401
    Abstract: A vehicle suspension subsystem is provided having a leafspring that is mounted to a vehicle frame with a clevis type mounting bracket. An end of the leafspring includes an eyelet which receives a bushing, the bushing in turn receiving a pivot. The clevis type mounting bracket is mounted to the vehicle frame and consists of a metal plate fastened to an L-shaped casted bracket. The metal plate and L-shaped casted bracket have aligned apertures which define a pivot axis. With the pivot being located in the bushing and the bushing located in the eyelet of the leafspring, one end of the pivot is disposed in the aperture of the metal plate and the other end is disposed in the aperture of the L-shaped casted bracket, allowing the leafspring to rotate about the pivot axis.

  • Publication number: 20100127444
    Abstract: A suspension system suitable for a trailer incorporates a device for limiting rotation of an axle received in an eye of a leaf spring. The leaf spring has a wrapped end defining the eye extending transverse to the leaf spring with a gap left between the leaf spring and the wrapped end thereof. The rotation limiting device is fixed to the axle and features a sleeve having a peripheral wall extending circumferentially about the axle inside the eye of the leaf spring and a tab projecting outward from the peripheral wall of the sleeve and extending in a direction parallel to the axis. The tab projects into the gap left between the leaf spring and the wrapped end thereof to block rotation of the axle and sleeve relative to the wrapped end of the leaf spring. Friction fit, adhesive, welding or multi-piece hardware fixing of the spring is avoided.
