  • Patent number: 5758425
    Abstract: A circular saw has a housing enclosing a motor for driving an output shaft about an axis of rotation. An upper bladeguard is immovably secured to the housing and has a rear wall defining an arcuate slot. A rectangular base plate is pivotally attached at its forward portion to the saw housing for swinging movement about a pivot axis parallel with the output shaft and disposed substantially forwardly thereof. An arcuate bracket arm has one end thereof connected to the rear of the base plate. A fastening element is mounted on the other end of the bracket arm and is received within the slot in the upper bladeguard. The operator may adjust the base plate by grasping the fastening element and moving the same along the slot in the upper bladeguard.

  • Patent number: 5010651
    Abstract: A portable circular saw with a 60.degree. bevel cut capability that is provided by a combination of blade diameter, height of front and rear pivot points above the footplate, the ability to tip the saw about a front hinge point to avoid projections contacting the footplate at a 60.degree. angle and recesses and orifices provided in the footplate at points where interference would normally occur between the motor housing assembly and the saw blade when the blade is at a 60.degree. bevel angle so as to prevent any interference of the footplate with the motor housing assembly and saw blade. A positive stop is provided at angles of 45.degree. and 60.degree..
