Contiguous, Relatively Adjustable Blades; Or Blade Having Relatively Adjustable Earth-engaging Parts Patents (Class 172/815)
  • Patent number: 5513453
    Abstract: A combined snow plowing and snow throwing vehicle includes an elongate plow blade at its forward end. The plow blade can be shifted to direct snow to either of the right or the left and includes separate snow throwing fans mounted, respectively, at the right and left ends of the plow blade. A user-actuable control system provides independent actuation of the snow throwing structures so that the snow throwing structure at the downstream end of the plow blade is actuated regardless of whether the plow is directing snow to the right or to the left. This enables the vehicle to plow and throw snow to either the right or to the left and further enables the vehicle to clear snow while traveling both up and down an airport runway.

  • Patent number: 4909330
    Abstract: An automotive earth moving vehicle for civil and military applications. The lade is movable with respect to the body by two independently operable sets of fluid driven actuator sets which are in intersecting spatial relationship. Each actuator set is arranged symmetrically with respect to a vertical median plane of the blade and its actuators are in parallel spatial orientation with respect to each other. One set of actuators is designed for lifting and lowering the blade while the other set is designed to bring about oscillation and tilt. The blade comprises two segments horizontally linked to each other and is thus adapted to alternate between a dozer mode and a plough mode. Wing members may be provided for attachment to the two flanks of the blade in the plough mode.The vehicle also comprises a sensor for use in the plough mode adapted to feed the blade movement control with data on the terrain.

  • Patent number: 4723609
    Abstract: A scraper for use with a two point bucket hitch of a tractor. The scraper provides a resiliently deformable blade depending below a rigid blade so that the deformable blade might be independently used by regulating blade height above a surface. The scraper has a primary medial blade member with pivotally connected lateral wing blade members on each side, which may be independently moved. The lateral wings releasably carry inwardly projecting tines to releasably engage and support coherent masses of material such as baled hay. A releasably attachable bottom pan converts the blade structure to a bucket. The scraper is particularly adapted to move animal excrement over flat surfaces of agricultural structures for accumulation and remove it therefrom for disposition.

  • Patent number: 4506741
    Abstract: A farm implement adapted to install plastic lined irrigation gates in rice levees and the like to aid in flood control. The machine comprises an elongated, rigid frame comprised of a trio of rigid struts. The rear of the frame terminates in a rigid scoop of concave cross section having a width somewhat wider than the frame. An elongated dipper blade, also of concave cross section, is pivotally coupled to the frame in spaced-apart, generally parallel relation with respect to the scoop. The dipper blade may be removed by hydraulic means between dirt cupping, dirt releasing and ground engaging positions whereby to dig a suitable contoured trench adjacent the levee after a hole has been cut by the scoop. A plastic sheet is then placed over the hole and trench, and dirt from the dipper blade is deposited upon the plastic sheet to secure same. Prior to cutting another gate, the dipper blade is drawn over the plastic sheet and the dirt deposited thereon to properly contour the gate for subsequent flood control.

  • Patent number: 4372617
    Abstract: An edging apparatus for an ice resurfacing machine includes a guide operatively attaching to one of the side edges of the machine which is capable of being extended from the side of the machine such that it can contact an upright surface as, for example, a rink wall or a dasher board extending around the perimeter of an ice rink. Associated with the guide is an ice shaving blade which is capable of extending in a vertical direction upwards and downwards between a shaving position wherein it can contact the ice surface and shave the surface and a non-shaving position wherein it is lifted upwards from the ice surface. The guide is interposed between the end of the edge of the blade and the dasher board or the rink wall such that it is impossible to catch the end of the blade in the wall or dasher board yet it is possible to correctly position the end of this blade very close to the wall or dasher board allowing shaving of the ice surface to a point almost immediately adjacent to the wall or dasher board.
