  • Glazier's point driver
    Patent number: 4369909
    Abstract: The glazier holds the toe of the driver on the glass, adjacent the edge of the sash, such that a handle trigger can be operated to drive the lowermost point from the magazine into the sash by the action of a coiled compression spring. The magazine has an insert associated with it so that points of various size can be accommodated in a single point driver. Since larger points require a greater spring force, means is also provided for conveniently adjusting the compression springs displacement. The guide block and push plate assembly for driving the points into the sash are slidably supported in the frame so as to precisely engage only the lowermost point in the stack.
