  • Cutting angle indicator in jigsaw housing with dust extraction
    Patent number: 9981327
    Abstract: A jigsaw generally includes a housing containing a motor activated by a trigger assembly. The housing defines a window. A shoe member pivotally connects to the housing. An indicator wheel is disposed in the housing so that a portion of the indicator wheel is visible through the window, wherein pivoting of the shoe member relative to the housing causes the indicator wheel to rotate.
    Type: Grant
    Filed: September 21, 2007
    Date of Patent: May 29, 2018
    Assignee: BLACK & DECKER INC.
    Inventors: Louis A. Gibbons, Weston J. Van Wambeke, Ruth M. Keffer, Michael F. Cannaliato, Brent A. Kuehne
  • Control of reciprocation speed and orbital magnitude of a jigsaw with a plurality of material and/or task descriptive icons
    Patent number: 9827623
    Abstract: A jigsaw generally includes a housing containing a motor activated by a trigger assembly. A single control member is connected to the housing and configured to be accessible by a user. A reciprocating shaft moves at a reciprocation speed and at a magnitude of orbital motion when the trigger assembly is in a retracted condition. The single control member is operable to be positioned among a plurality of positions. Each of the positions corresponds to a predetermined combination of values of the reciprocation speed and the magnitude of the orbital motion.
