Tti'ioll whom it muy conce-rit:

Be it known that We, Joint ll. Hur?. and.

` Sashes, oi which the following .is a speoilication, reference being had therein to the ac com onying drawing.,

T is invention relates to improvements in swinging sashes and has for its )rimary object the provision of imoroved means for sealing the s' ace intermediate the border olflthe sash am the :window casing or frame .agalnst the admission ot dust, moisture, au,

etc., and more particularly the splice beneath the bottom edge of the sash.

The lnventlon comprehcnds the provision of a spiing metal Weather strip interposed between the lower member of the sash 'trame and the bottom member of the sash secured at one edge t'o one el" said members and having a freely movable projected edge portion to spring behind an oppositelyv projecting portlon of the member to which it is unet tached, said portion terminating in a roundso f closing movement ol the sash;

A convenient embodiment ofthe invention embraces the provision ol n strip ol' the character described vsecured at one edge to the bottom member of the sash and having its inner edge Atree und projected downwardly and inwardly from the sush, and the bottom member of the sash frame or casing being provided with a portion, for insta-nce, a stopst ip, behind the inner edge of which the-free edge of the stripis adapted 'to spring, and also preferably nnpinge thoreagalnst, when the sash is closed. the tree edge of the strip terminatingP in a llange bent upwardly therefrom and projecting into, whereby to play in, a slit or `groove in the sash. f

The novel features in the construction and Aarrangement of the several parts of our structure will be apparent from the detail descrip tion hereinafter contained,- When read in conforming part hereof.

'In the drawings, Figure l is a perspective View of one corner of a window casing or frame, and the swinging sash hinged thereto,

nectionl with the accompanying drrovingsv 'including the Weather strip interposed be tween the same; Fig. 2 1s a transverse sectional view through the 'trame and sash, the sash being shown in closed position; and Fig. 3 is a sectional `View transverse through one ot' the side members oil: the casing.

Referring;f more specifically to the drawings, wherein like reference characters designate correspoinling parts in the several views, A designates one oi" the vertical or sid members ol the frame or casing,.B the lower member thereof, C the side et the swinging sush hinged as ot D te the member A, and E the bottom member of said sash. The sides and top (not shown) ot the sash are grooved as at F for the reception ol" the sealing flange G of a 'weather strip il, secured to the tace of the member A, this particular strip being of a 'type Well known in this art.

lrojecting upwardly .from the surface of the trame member B, we provide a stop-strip l having at its outer upper edge an' inclined metallic insert J lor a purpose as will presently appear, said insert being at the end of'- the stop-strip nearest the hinged edge o the sash.

K represents an inwardly and downwardlgr turned portion of theJ spring; metal weather i strip constitoting?Y a characteristic feature of the present improvement. Extending outwardly from said portion and arranged to lie flat upon the bottom surface of the mem ber E of the sash, is a securing ortion L tacked to the sash us at M and projected at its edge into a'kerf N in the sash, the 'outer face of the sash having a depending portion O arranged to abut the outer surface of the stop-strip l when the sash is closed. The

strip is b ent upwardly es at P to )rovide a roundedv r smoothl edge Q to taci itate the riding .fof 'the same over the stop-strip VI, this upwardly bent portion of ilonge P extending into and having free vertical movement in n. groove R formed vbetween the outer sul fac-eel the sash and a piece of molding S secured to anu constituting a part of the lower member E, of said sash.

When. the sash is closed from en open position represented in' Fig. 1,-, the inner corner'of the weather stri or edgeQ will 'irst' comein Contact with t ie inclined surface of the metallicinsert il and, owingto the'gradual upward'inclination of such 'surface','th'e stri?) 1n riding,r thereover will be correspondinor y elevated, such movementA -beingper-- nntted by the Ila! O'e l) moving vertically' in' the upper surface of the stop-strip l over which it will ride until projected inwardly thereheyond when the free edge of thestrip will spring downwardly behind the inner' 5 surface of the stop-strip and forcibly impinge upon the corner or edge thereof, see Fig. 2. By the arrangement of the parts as hereinabove described, we provide -a highlv efficient, simple, and durable sealingengagel ment between the lower member of the window frame or casing and the bottom member of the swingingl sash.
