The lower lever 7 21s able grooves at its SlClQS in the framework of provided with an armportion, at the outer window, and asash cord secured at'the ends end of which one end'of a rod 79 is opera- 95 to the sides ofthe respective sashes, forming tively connected therewith.

When the rod 79 is actuated to the right, the braking action on the weighted member 10 will be released, as will be readily understood. vVith this arrangement,the window sashes may be operated to slide up and-down or jointly, and also thev 10 'may be properly and 78, enabling smooth operations of the sashes.
