This invention relates to improvements in window construction,. and particularly to windows of the sliding sash type.

One object of the present invention is to provide a construction and arrangement whereby the upper and lower sashes may be raised and lowered in the same manner as ordinary window sashes, and wherein the construction and .arrangement is such .as to enlU able either or both of the saslies to be tilted or swung inwardly topositions at various degrees of angularity with respect to the window casing or frame in a manner to provide A convenient access to the Aouter side of the window glass for the purpose of lwashing or the like.

Another object of the invention is .to provide a novel construction and arrangement wherein the 'ordinary Vcoiinfterweights and sash chains or cords are employed for supporting the sashes in various ltilted positions of angularity with respect to the window frame in which the sashes are adjustably mounted. f l p Another object of the invention yis to provide novel and suitably positioned fulcrums around which the upper and lower sashes may be tilted, and supported by the sash chains at various angles with respect tothe '30 window frame.

Another object of the invention is to provide a novel form of metallicA weather stripping comprising a feature of the present invention, and particularly adaptable for use in connection with-windows of the character disclosed in the illustrative embodiment shown in the drawings. p

A further object of the invention yis to provide a novel form of finger .or vbolt conguiding means, whereby the bolt may be conveniently manipulated to various positions` and read-ily secured in such positions in a manner to prevent accidental displacement therefrom. v

A. still further object of the invention is to improve devices ofthis character in sundry details hereinafter described and particularly pointed out in the appended claims.V A

Fig. l0 is a sectional plan view ofthe parts shown in Fig. 8, the view being taken substantially as indicated by thev line 10-10 thereof.

In the illustrative embodiment .of the invention, a window Vframe or casing, indicated as a whole by the numeral V11, is provided with upper and lower window sashes 12 and 13, respectively, to which are attached one end of the vusual sash cords or chains 14 and l5 adapted to be trained over pulleys 16 and 17 rotatably mounted in outer and inner pulconnected and operable to counterbalance the upper sash 12, and the latter, to counterbalance the lower sash 13. Y

For slidably mounting the sashes 12 and 13 in the frame 11, the pulley stiles 18 and 19 are provided with vertically disposed slots 22 and 23, respectively, and the sashes 12 and 13 are provided adjacent their lower edges with trunnions 24 and v25 adapted to vengage the slots 22 and 23 of VtheV frame. Suitably positioned in the side fra-me members of theV sashes 12 and 13, adjacent the upper portions thereof, are bolts or lingers 26 slidably mounted in frame members 27 and adapted to be projected into sliding engagement with the slots 22 and 23 asi'ndicated by full lines in Figs. 3 and 5 and by dotted lines in Fig. 10. It will be observed that by such an arrangement of the trunnions 24 and 25 and bolts 26 Ain the slots 22 and 23, thesashes 12 and 13 may be raised and lowered in the frame 11, as is customary in the ordinary window-construction, and that the engage- Y ment of the trunnions and bolts with the slots prevents any lateral movement of the sashes V,and conveniently accessible for 4adjustment therein.

It will beobserved by reference to Figs. 9 Y

and 10 that by turning the member 30 counterclockwise. the bolt and finger grip meniber may be moved from the full line position to the dotted line position shown in Fig. 10, and by rotating the member ina clock- Vwise direct-ion, the shoulder 31 on the inember 30 will be forcedsnugly against the outer face of the frame member 2'? in a manner to frictionally secure the bolt in adjusted position, either in or out of engagement with the slots 22 and 23 of the stiles 18 and 19.

This type of bolt construction is most desirable ina window structure or" the character described as it provides conveniently actuatedV means for positively securing the ,i 'bolts inoperative position inthe slots in a manner to prevent accidental displacement v.therefrom and insure efficient operation ot' thedevice, j Y

Y For providing' convenient-n ,accessV tothe outer facevof the windowsashes 12 and 13, the boltsn26 are withdrawn from engagement `withthe slotsV 22 and 23'andltheisashes lmoved,upwardly in the iframe or casing V11 until the VYtr- unnions 24 and 25 may be. posiitionedin notches 32 and 33 formed adjacent to and communicating with the slots 22 and 23, respectively, intermediate their end portions, thereby providing ulcrums about which the sashes 12 and 13 may be tilted inwardly at various angles with respect to the r window frame 11, for example, to the pesitions shown in Fig. 2, in which positions the upper or free end portions ot the sashes 12` and 13 are supported by means oi thesash chains 14 and 15, the sash weights .20,and 21 v serving to counterbalance the weight ,of the sashes in their tilted or adjusted positions.

ByV connecting the sash chains 14 and 15 t0 the side frame members of the sashes 12 and 13 intermediate their upper and lower end yportions in a manner to support the upper end portions of the sashes when in tilted position, suitable provision is made for permitting the tilting of the sashes about their fulcrums without interference by the sash chains, and for this purpose the -outer longitudinal vertical edges of the side frame niembers of the sashes 12 and 13 are cut away down to the point of attachment of the sash chains 14 and 15, as indicated at 34 in Figs.

1, 3 and 5to provide ample space between the window trame 11 and adjacent portions of thev window sashes Jfor the passage or" the sash chains 14 and 15 as the sashes are swung inwardly to their tilted positions. v,

For suitably weather-stripping windows 'of the character described, the pulley stiles 18 and 19 are provided with wear plates V35, and between thel said plates and the stiles 18 andv19 are secured, by means of screws 36, the flanges or base portions 37 or" resilient metal weather strips 38, the yielding portions 390i which are adapted to be positioned between the outer `face of the lower sash 13 aiid the pulley stiles 18, and between the outer face of the upper sashV 12 and 4the weatherboard 40. Thus, it will be observed that when the sashes 12 and 13 are in their normal slidable position, as shown in Figs. 1, 3 and 5, the free edges of the portions 39 oi the weather strips 38 will yieldingly engage the outer faces of the sashes and provide a weathertight connection between the frame 11 vand the sashes 12 and 13. l

Y It will be observed from the foregoing description that the present invention prei/'idee a novel type of window construction wherein the sashes 12 and 13 are slidablv and tiltably mounted, andY wherein the sash chains or cords 14 and 15 and counterweights 2O and 21 serve, not only to support and counterbalance the weight of the sashes when in their normal or slidable position, but also to support the sashes when tilted at vario-us angles with respect to the frame. Y Y Y VFurthermore, the present invention provides a novel type of weather stripping particularly adaptable to windowv 4construction 'of the character described, and also anellicient and conveniently actuated bolt mechaniSm capable of being secured in operative position and also out of operative position to prevent marring of the window frame in the event that the sashes, for any reason,

j, should be moved from their desired tilted position to a point where the counterweights would act to suddenly draw the window sashes into alignment with the frame.

Obviously, the present invention is not limited to the precise construction and arrangement shown and described, as .the same may be variously modified. Moreover, all the features of the invention need not be used conjointly as the same may be used to advantage in variously different combinations and sub-combinations.

What we claim is new and desire to secure by Letters Patentis:
