Mounted in th'l hollow stile l() longitudinally of the latter and preferably extending substantialltv ite entire length` ie an adjusting Strip Q0 having somewhat the character of an elongated shoe and adapted for adjustable engagement with the bottom Wall of the groove l5 or lt'. as the ease nia'v be. This adjusting Strip is, as herein shown. a hollow or ehannelJshaped member having its closed side outermost.y and preferably ta pering in width from the eenter toward each end. The strip is seruretl to the stile with capacity for both angular and bodily movement by the following means: 21 and Q2 indicate a pair of bracket` that are suitably secured to the inner transverse member of the stile, one above the other. In the brat-liet 22 is pivoted a U-shaped link Q3. the outer or free ends of which are pivotally conneeted to the sidesof the adjusting strip :'50 h v a pivot-pin Q4. Said pivot pm also passes through an intermediate strip-actuatinglink 2r the upper port-ion 25a of which is reduced in size and passes freely through an aperture 2l* of the bracket 21, and terminates in a head or eap 2G thatI form` a etop for the upper end of a eoiled eompresaion y-pring :2T that rests upon the horizontal projeeting inevnher of the braeket 2l. To the lower end of the link 25 is, pivoted the outer end of a lever Sal lexer beiug [n.otally mounted at Q9 in and hetween the sides of the lower .sash har. and its inner arm being provided with a pinth-handle 30 projecting through an are-shaped slot 3l in the outer faee of the sash har and t-operating with a fixed pinch-handle eef-tired to Said sash har above the slot' ill.

vIt, will he ohaerved hv reference to Fig. 3 that the ml iu-.ting `drip or Aahoe 20 is of a tapering,` or wedge torni in eross-seetion, its opposite sides `ditlinglv engaging the elaatie lips lll oli tlu .Sitltw of the lstile` thel result 0f whit-h is that anv outward movement of the adjinting trip relatitel)v to the Stile, acting through aid pring lips. tends to compress the fares ot tht -tile into snug engagement with the de ,walla of the guide-groove. Furthermore. t he transversely `vieldin Charatter of the adjusting strip and of tizia lips engaged then-hv permite an automatic outward adjintment of the adjusting strip to aeeonunodate saah openings of more or less varying width.

lt i de`irahle. wpeviallt in the rase ot' ear windows` that the aaah shall have a Snug and elose lit in it 4 guide when in lo ed position for the exelusion of dust` eiudere, cold and inoiature. while at the rame time it i equallv leairahle to render the raising and lowering movements of the aaah as easzv an' pweihle. 'l`o .eeeure this result. l propose to malte the oppmite side walls of the guide or of the sugli. or of both through the length of the sash. of .slightlv varving width in a direetion tranaverse to the plane of the mah or sash opening, so that the narrowest parta ma)` he in closer engagement when the aaah is in eloaedy position. One form in whieh this prineiple mayy be embodied illustrated in Fig. Q of the drawing. wherein l have shown simply a pair of guidestripe fifi and 34 so applied as to he slightly eonvergent from a position opposite the upper end of the sash to a poaition opposite the lower end of the latter. thusy 'forniing a slightly tapering and downwardlv eontraeted guidegroove 35 in Whieh the transversely elastic side walls of the Stile 10. which ma)y also be similarly inclined, slide. From the foregoing it will be seen that when the sash ie in its lowered or Closed position the maximum compressive ett'eetupon the sides of the stile is exerted, While as the sash ia raised the stile enters the upper and wider part of the guide-groove and hence moves more freely therein` it being understood that the walls of the guide-groove above the top of the sash, when closed, are preferably parallel and of a width substantially that of the maximum width of the part of the guidegroove engaged by the sash when in closed position;

In Fig. 1 I havealso illustrated a simple lock which can he released by the same meehanism h v which therudjusting rstrip is release-. 1 so as to relieve the lateral tension of the sides of the stile upon the side walls of the groove; said lock consisting of a sliding bolt or plunger 36 guided b v a pin 37 plaving in a slot 38 of the plunger. and normally pressed into locking position by a compression spring 39. The lever Q8 has a depending finger 40 adapted to engage an upwardlv projecting lug 41 on the inner end of the plunger 36. Then the pinelnhandles fi() and 3Q are compressed to therebv draw down the link 25 against the spring 27 and therehv retract the adjusting strip Q0. the finger 40 at the same time, through engagement with 'the lug 4l, retracts the plunger 36, thereby unlocking the sash and permitting it to be raised. r

Although I. have shown the tapering feature for securing a maximum snug tit of the sash as applied to the sash guide, and cooperating with a transversely elastic stile, yet it is evident that the tapering feature might be applied to the sides of the stile, as well Whether the stile and guides, either or both are transversely elastic or rigid.

It is evident that, instead of relatively tapering the side walls of the guide, the bottom Wall of the guide might be inclined with or without a corresponding inclination of the edges of the stile. Also, with reference to the adjusting strip, while I have shown this as angularly movable in the plane of the sash, yet it will be evident that the same elfect might be produced by so.

mounting said strip as that it shall have an angular adjustment in a' plane transverse to the sash. i

I claim:

1. The combination with a hollow sash and a guide therefor, of an angularly movable'- adjusting strip mounted in said hollow sash and adapted to engage said guide, said adjusting strip being of wedge form in cross-section whereby, under outward move ment, it operates to force thesides of said sash into engagement with the side walls of the guide, substantially as described.
