  • Patent number: 9743580
    Abstract: A blade holder device for supporting and immobilizing blades when replacing or assembling a pair of blades on a lawnmower. The blade holder device includes an X-shaped frame having a first elongated support pivotally secured to a second elongated support. The elongated supports have an aperture disposed in the center thereof in order to receive a fastener therethrough. Each elongated support further includes a first and second pair of segments permanently attached to the ends thereof. The pair of segments include a recessed area therebetween in order to receive a portion of a blade therein. The device is removably attached directly to the underside of the deck of a riding lawnmower. The device can be placed over a pair of blades to prevent injury of an individual removing or assembling the blades and to prevent damage to the blades themselves.

  • Publication number: 20130277903
    Abstract: A vise jaw plate includes a plurality of equally sized holes arranged in a pattern and extending through a front side of the vise jaw plate which cooperate with dowel pins and work holders to position and support a work piece. Horizontally spaced mounting bores are arranged for cooperative alignment with vise jaw mounting holes to permit the attachment of the vise jaw plate to the vise jaw. The mounting bores include a first frustoconical portion, a second frustoconical portion and a straight bore portion joining the confronting narrow ends of the first and second frustoconcial portions. The mounting bores and the vise jaw mounting holes have offset center-lines that become coaxially aligned during attachment of the vise jaw plate to the vise jaw causing the vise jaw plate to become fully seated against a deck surface of the vise.

  • Patent number: 8256753
    Abstract: A multi-station machine vise that is disclosed herein that utilizes soft jaws, which are symmetrical and machineable on all four sides. The jaws being identical in size and configuration makes them interchangeable/usable on any vise station, which results in reduced operating costs. The movable jaws are precisely located and fastened to the vise utilizing a jaw carrier, which incorporates a pull-down action to eliminate jaw lift. The jaw carrier includes a downwardly positioned wedge design that engages a corresponding wedge on a slide that moves the jaw carrier and the jaw. Incorporating the pull-down mechanism into the jaw carrier disposed between and slide and the jaw allows for simplifying the design and manufacture of the jaws.
