  • Patent number: 9752854
    Abstract: An assembly structured for removably mounting armor on a user's body in a protective orientation including a base having an inner portion and an outer portion. The inner portion is structured to retain the armor, preferably but not exclusively, in the form of an armor plate on the base in substantially facing relation to the body of the user, wherein the outer portion is disposed in overlying, covering relation to the armor. Preferably the base is formed of a rigid material and an attachment assembly is connected to the base and structured to facilitate the operative and removable mounting of the base and the armor on the user in a predetermined protective orientation. The attachment assembly may also include a plurality of connectors and a common release mechanism, wherein the base and the armor can be quickly and easily removed from its protective orientation and operative mounting on the user.

    Abstract: A turf cutter device, an infill extractor/collector device, and a turf wind-up device are used to facilitate the cost-effective removal of an infilled synthetic turf and the subsequent installation of a new turf at the same site, with minimal subsurface disruption. An infill extractor/collector device mounted on a motorized vehicle moves a relatively narrow strip of filled artificial turf from the surface, in front of the vehicle, and directs the strip to an infill removal station. The infill removal station inverts the strip and redirects the strip back toward the front of the vehicle, after agitating the strip to extract the infill. After redirecting the strip toward the front of the vehicle, the vehicle drives over the unfilled strip. Meanwhile, the extractor/collector device moves the extracted infill rearwardly to a bag located in a trailer.

  • Patent number: 6370997
    Abstract: A transportable circular table saw having an exterior housing (1) with a tabletop (4) forming a workpiece support surface (3) that is irreversibly arranged in the exterior housing (1), and a saw unit (7) arranged underneath the tabletop (4) with a drive motor and a circular saw blade (10) protruding into the tabletop (4) from below through a saw slot (9), with the exterior housing (1) in plan view being approximately square in shape. The sawing unit (7) is slidable relative to the tabletop (4) in a pulling direction, as a result of which the circular saw blade (10) moves in the saw slot (9) in the pulling direction, and in relation to an axis of a mitre cut in the pulling direction, preferably being able to be inclined to at least one side. The tabletop (4) forms the workpiece support surface (3) and the saw slot (9), is rotatably held in the exterior housing (1) on an axis perpendicular to the workpiece support surface (3), in particular in a surrounding top (14) of the exterior housing (1).

  • Publication number: 20020033085
    Abstract: A guiding device for a rotatable, circular saw blade of a house-building saw. Such a saw comprises a bench-shaped stand (2) with a frame (98) which is movable therein and on which the saw blade (12) is rotatably mounted, and an operating mechanism (26) for raising and lowering the frame (98) in the stand (2). According to the invention the guiding device comprises guide elements (90, 92) whereby the frame (98) can also be moved along the bench surface (4) after the frame (98) has been moved to near an upper position.

  • Publication number: 20010032534
    Abstract: A machine tool has a work table which defines a working surface and has a cutting tool which is attached to and movable with respect to the work table. The position of the cutting tool with respect to the working surface is controlled by a mechanism which elevates the cutting tool with respect to the working surface and angulates the cutting tool with respect to the working surface. The cutting tool is mounted to a support plate which is pivotably attached to the work table. The elevating mechanism includes a threaded rod and a nut which engages a pivoting link. The pivoting link also engages the cutting tool. Rotation of the threaded rod pivots the link which in turn raises and lowers the cutting tool. A spring biases the cutting tool towards its lower position to remove play between the components. The angulating mechanism includes a lever, two cams and a locking rod. Rotation of the lever moves the locking rod longitudinally due to the action between the two cams.

  • Patent number: 5479971
    Abstract: A dual action tree cutting apparatus includes a single generally planar blade mounted on a shaft at the forward end of a support frame, with the blade projecting forwardly therefrom. The blade has a cutting edge extending around the entire perimeter, and has two mirror image halves divided by a centerline passing through the shaft. Each blade half cutting edge increases in the distance between the cutting edge and the shaft along the perimeter from a rearward end of the centerline to a forward end of the centerline. A set of cutting teeth are formed on one blade half and oriented to cut a tree when the blade is rotated clockwise, while a second set of cutting teeth are oriented on the second blade half perimeter to cut a tree when the blade is rotated counterclockwise. A sprocket on the shaft is engaged by a pair of drive chains connected to operable cylinders, the cylinders operable to retract and pull one drive train to rotate the blade in each direction.

  • Patent number: 5413017
    Abstract: A paper tail ripper having a pair of rotatably mounted knives, air motors which counter-rotate the knives and a deflector which deflects the paper tail toward the knives. The knives traverse closely spaced overlapping circles as they counter-rotate. The deflector sweeps the paper tail onto a transfer mechanism, which transfers the paper tail away from the ripper, so that the tail may be threaded through a calender stack, etc. The ripper is pivotally mounted on the transfer mechanism for movement between storage and operating positions.

  • Patent number: 5159869
    Abstract: A cutting station comprising a bed; a work surface supported on the bed; a carriage traveling along the longitudinal axis of the bed by virtue of a first motor; two cutting members connected to two second motors; and a structure supporting the cutting members and second motors, and designed to travel, by virtue of actuators, along vertical slideways supported on the carriage, and to be carried by the carriage during traversing of the same. The bed comprises two fixed parallel beams supporting the work surface, and a first of which also supports two horizontal slideways for supporting and guiding the carriage. The center of gravity of the second motors lies within the space defined between the horizontal slideways.

  • Patent number: 5134913
    Abstract: A machine which is constructed for slitting travelling webs, such as corrugated boards or similar material, characterized by a slitting tool with the shape of a thin rotary blade, which is provided with a cutting peripheral edge. The rotary blade is contained within a holder so that only a small portion of the cutting edge will emerge from a narrow slot in a wall of the holder, which wall is placed very close to the path of the web. The holder also contains a liquid for cooling and lubricating the rotary blade.
