The clamp shown in Figs. 5 and 6 is used to clamp sash on allfour sides. Tlie end clamps E E are operated through the rod Bwhich is connected to one end of the lever C, the left hand onebeing connected to the lever through the rods F and G. Theopposite clamps H are held by set screws, and may be adjustedin the slot in which they are set. The side clamps are connected.

The treadle is held in the clamped positionby the notched lever S, which has two sets of notches at rightangles to each The notches on the side are used to en-gage the treadle A, which operates the end set of clamps, v/hilethe other notches are used for the treadle K, which operates boththe side and end clamps together.
