To all whom it may concern:

of'Boston, in the county of sufi'olk andg State of Massachusetts, a citizen of the.

V The object of my invention is particularly to provide for an airtight closure of the window when the sash is occupying aclosed position and at the same time to'perm'itof "an easy opening and closing of the'sash.

The invention can'best be seen and pnderstood by reference to 'the drawi'ngs; fin I A v p v run intoone anotliento form a united inwhich-' Figure 1 is a frontelevat on of a window. 2 is a section onthe line- Q-fi of Fi 1. f%ig. 3 is a section on the line 3 30f ig, tisthe seine esg lf ig. 3 except that the sash isgshown occupy; t ion' as will later be exp aine "Referring to the drawings 1 represents the frame and 2 the sash.

In a window, the combination comprising a sliding sash, means framing said sash whereby it may have a sliding move ment to open and whereby also the sash when closed mayhave an appreciable movement of translation perpendicular to the plane of the sash, said framing means bearing seal-forming parts extending around the sash and against which .the sash bars are adapted to have bearin means for holding the sash when close against said seal-forming parts, members embracing the sides of said sash and movable translatably therewith and in which the sash isislidable, and means engaging said members whereby the sash will be held outwof contact with said seal-forming parts during theisliding movement of the sash.
