  • Patent number: 6274190
    Abstract: An apparatus for coating seeds and particulate material includes an elongated tray operably mounted on a support frame with a motor for oscillating the tray to move particulate material from a rearward end to a forward end therealong. The tray includes a perforated support surface with a saw-toothed cross-sectional shape such that the particulate climbs the inclined tread of each sawtooth and drops from the forward end of one tread to the rearward end of an adjacent tread to form a “curtain”. A plurality of spray nozzles are located over the tray to direct coating solution onto the seeds as they move along the tray. Preferably, the nozzles direct spray towards the curtain of falling seeds between the treads. An upper housing on the support frame includes an air plenum which directs air downwardly onto the seeds on the support surface and through the perforated support surface to a second air plenum formed under the support surface.

  • Patent number: 5721012
    Abstract: An apparatus is provided for continuously coating particulate material, such as seeds. The apparatus includes a frame, a cylindrical drum rotatable about an axis tilted with respect to a horizontal plane, and a series of spray nozzles extending into the drum so as to spray one or more coating solutions onto the particulate material which tumbles within the rotating drum. The drum includes a rifling with flighting which carries the material upwardly from approximately 6 o'clock position to a 9 o'clock position, wherein the material falls from the flighting in a curtain spaced apart from the sidewall of the drum. Perforations in the sidewall of the drum allow a flow of air through the drum and curtain of material so as to dry the coating solution on the material substantially instantaneously as the material is coated with solution in the drum. The drum is maintained at a negative pressure during the coating process.

  • Patent number: 5716186
    Abstract: A gondola moving system is provided for moving fully loaded gondolas in lateral or longitudinal directions. The gondola mover includes a plurality of lift assemblies, which can be sequentially connected to one another, depending upon the length of the gondola. Each lift assembly includes a lift arm having a first end extending through the gondola posts, and a second end mounted upon a jack assembly. A base bracket extends between the lift arm and the leg of the gondola. Connecting bars extend between adjacent lift arms. The lift assembly components are quickly and easily assembled and installed upon the gondola without the use of tools.

  • Patent number: 5494709
    Abstract: An apparatus is provided for uniformly coating particulate material. The apparatus includes a frame, a cylindrical drum rotatable about an axis tilted with respect to a horizontal plane, and a spray nozzle extending into the drum so as to spray a coating solution onto the particulate material tumbled within the rotating drum. Perforations in the side wall of the drum allow a flow of air through the drum so as to dry the material within the drum as it is coated with solution. A vacuum system removes the coated seeds from the drum without manual handling. In operation, the seeds form a dense mass, and migrate away from the mass as the seeds increase in size and weight from the sprayed coating. Eventually, all of the particles are uniformly coated, and thus a new mass is formed and the process repeated until the material reaches a desired size.

  • Patent number: 4955651
    Abstract: An adapter for attaching a universal latch to a hook. The adapter consists of a spring formed into two helical end coils connected by an U-shaped intermediate section. The adapter fits over a flange on the hook with the end coils in axial alignment with a latch mounting hole through the flange. The end coils fill excess space between the flange and the latch and center the latch on the flange.
