  • Patent number: 9451741
    Abstract: A vacuum planter exhaust filtration system for preventing seed treatment particles used in seed planting from entering the atmosphere. The vacuum planter exhaust filtration system generally includes an air filter fluidly positioned between the fan and the planting units of the vacuum planter. The air filter removes the particulate material prior to being exhausted into the surrounding environment by the fan. The air filter utilizes cyclonic separation to separate the particulate material from the contaminated air from the planting units. A particle container collects the removed particulate material and allows for environmentally friendly disposal of the particulate material.

  • Patent number: 6098301
    Abstract: A chain measuring system which allows quick and simple calculation of the number of links in various types of chains such as roller chain, saw chain or link chain. The inventive device includes an elongated member, a plurality of equally spaced notches within a side of the elongated member forming a plurality of pegs, each of the pegs having an arcuate end, a plurality of link count indicia within the elongated member and adjacent each notch, and a length indicia within the elongated member. The rollers of each link of a roller chain are removably positionable within the notches. The link count indicia indicate how many links are within the chain by the user simply viewing the link count indicia adjacent the last link. Preferably, the elongated member includes an augmented portion which provides space between the pegs and another surface such as a wall.

  • Patent number: 5528855
    Abstract: A foldable artificial mulch cover has a slit installation feature with an intact periphery. The cover includes a flexible flat sheet, a central opening defined in the sheet for passage of the stem of the plant, a slit defined in the sheet extending along a line passing through-the central opening in the sheet with each end of the slit terminating adjacent to but inwardly from a perimeter edge of the sheet, a plurality of paired apertures for the passage of U-shaped staples to secure the sheet to the ground, a fold line passing through the central opening with each end terminating at the perimeter edge of the sheet and being perpendicular to the slit, and a plurality of slots for the passage of water through the sheet.

  • Patent number: 4541267
    Abstract: A hand-operated tool for straightening a bent body of a sickle guard has an elongated handle supporting a shroud and fulcrum member. The fulcrum member connected to the end of the handle has spaced projections providing a recess for accommodating a portion of the sickle guard. The shroud adjustably mounted on the handle adjacent the fulcrum member has a converging pocket for accommodating the body of the bent guard so that, on movement of the handle, the shroud supplies force to the bent body of the guard to straighten the bent body and align the guard with the sickle. A releasable fastener secures the shroud in an adjusted position on the handle.
