This invention relates to window construction and more particularly to devices applicable to either new or old windows of the standard sliding sash construction, by means of which the sash will retain their sliding capacity, but can also be rotated on a horizontal axis to swing into the room either for ventilation purposes or to clean the outer surface of the glass.

The object of the invention is to provide attachments of a simplified character involving relatively few parts which can be used to convert standard sliding sash into sash both slidable and pivoted, while effectively controlling the sash during the pivoting movement a ainst any sliding movement and, conversely prohibiting any pivoting movement during the normal sliding motion of the sash.

A further object of the invention is to provide devices of the character indicated lending themselves to the eificient sealing of the sash with respect to the window frame to prevent the passage of air between the sash and the frame.

Further objects will more particularly appear 'in the course of the following detailed description.

attached to the lower end of a slide member.

In the drawings accompanying this specification. a standard window frame F associated with sliding sash S is provided with improved devices by means of which the sash can be raised or lowered as usual and may also, as desired, be rocked on horizontal pivots into the room or back into the sliding position in the sash frame. In the .case of old windows, the only modification required is the narrowing of the sash to a width not greater than the distance between the confronting faces of the opposed parting strips. Preferably, the width of the sash is made somewhat narrower than this distance between the parting strips to permit the use of weather strips which, of course, must pass when the sashes are tilted.

Within the stile grooves of the standard window frame are secured guide members I, which extend the full length of the stile grooves, each of these guide members being preferably formed from sheet metal as illustrated in Fig. and comprising a strip bent longitudinally to provide side wall portions 2-2 and inturned flanges 3-3. Preferably, the strip will be still further bent back and under the side flanges 3--3 as at 4 to provide smooth rounded confronting edges for said flanges 3-3. The base portion I is provided with suitably spaced screw holes 5, by means of which the guide strip I can be rigidly secured, i

one in each stile groove of the window frame. Adjacent the upper end of each guide I is a cutout slot I2 intended to surround the pulley slot in the stile groove, through which the standard window cord will extend for attachment to the top of each sash.

Associated with each of the guide members I are slide members 6 (see Fig. 4), whichslide members 6 are formed with a rear, marginal flange '1, against which a sash will abut in its sliding position. Associated with each of themembers 6 are spacedflange portions 9 extending longitudinally of the slide, whichflanges 8 may be formed as the marginal portions of astrip 8 rigidly secured parallel to theslides 6. The upper end of each of the slides 5 is provided with slot I I adapted to receive locking bolts carried on the upper edges of each sash to secure the sash in fixed relationship with theslides 6. To the lower end of eachslide member 6 is secured a pivot lock device Ill carrying a pivot removably securable to the bottom end of the sash stiles in slots I 1 formed therein. The overall length of eachslide 6 and associatedpivot lock device 10 is that of a sash.

To the side edge of each sash is secured one part of an improved weather strip device I3, which comprises a longitudinal strip slightly wider than the thickness of the stile and bent on one edge to form a loop l4 adapted to receive a longitudinally extending flange I5 formed on a resilient strip I6 which is bent transversely to form a convex sliding surface adapted to tightly engage the surface ofslide member 6 when the sash is in normal sliding position with respect to theslide 6.

Two forms of pivot locking devices for the sash are disclosed herein.

The form illustrated in Figs. 16-18 comprises ahousing 18 within which is a boss ZI for slidingly receiving the end of abolt 20 with acompression spring 22 normally operating to force thebolt 28 from the housing- When thus forced from the housing the end ofbolt 20 will frictionv ally engage aside wall 2 of the guide member I with suflicient strength to resist the lifting effect of the sash weight and hold the sash against sliding while the sash is pivoted inwardly. To

control the bolt 20 a right-angle lever is provided, one end 2'6 of which is journaled in the housing j I8 and is formed with a radially directedlug 21 adapted to play in aslot 28 formed in thebolt 29. Theopposite end 29 of this lever'extends beyond the coveringplate 23 of housing I8 through .a, suitable journaljziand is adapted to be inv sorted in a slot II formed in the edge of the sash stile adjacent its bottom, so that the sash will rock with thearm 29 pivoting on thearm 26. From this construction it will be observed that as the sash does rock witharm 29, thus turningarm 26, the keeper 2'! will be moved to the left, as illustrated in Fig. 17, and bolt 20 will be forced outwardly byspring 22 to lockingly engage the side wall of guide I so long as the sash is beyond its normal sliding position. Each of the housings I8 is associated with a coveringplate 23, the upper portion of which extends above the housing I8 and is provided with screw holes 3D30, by means of which this locking device can be associated with the lower end of a slide member as illustrated in Fig. 8.

A modified form of pivot control device is illustrated in Figs. 24 and 25, in which a housing I8 is provided arranged to slidingly accommodate a bolt 29' having a similar notch 28' and normally forced outward as by compression spring 22'. The housing is provided with spaced journals 3I3I, one of which journals 3i, is adapted to receive and pivot the inner end of arm 26', while the other journal 3i, provides a bearing for a keeper 33 having one portion adapted to engage bolt 20' within notch 28' and an outwardly extending portion adapted to pass through a covering plate 24' having anorifice 34 and a bearing and also through astrap member 23 provided with abearing 25, asimilar orifice 34, and also screw holes 353, by means of which the entire pivot control device can be secured to a slide member as illustrated in Fig. 25. I he outer portion of the keeper 33 is secured by screws to acontrol device 35 which comprises a plate pivoted on arm 25' of the operating lever and having an inwardly directedflange 38 adapted to contact the back face of a sash when theouter arm 29 is associated with the sash. In this form of the device it will be apparent that so long as the sash is in its vertical position its back wall will bear against theflange 36 and thus retainbolt 20 in its retracted position through keeper 33. When, however, the sash is pivoted inwardly on arm 26', the pressure againstflange 36 is relieved and the bolt 2 I is instantly projected into locking engagement with the guide member, thus locking the sash during its further pivoting movements. The control arm 29' is, however, relieved of any pressure during the pivoting of the sash.

To secure the sash in normal sliding position and against pivoting movement, a locking device is provided positioned on the upper edge of each sash and this device as herein illustrated in Figs. 13-15 comprises three parts, each of which may be preferably constructed as a unit and associated by links of variable length to accommodate same to sashes of difierent widths. With this object in view each of the end bolt parts will be provided withsimilar housings 35. The central operating part will be provided with ahousing 36 and supplementary housings S'I of the same general outer shape, will be provided to connect the central operating part with the end bolt parts depending on the width of the sash. The central operating part comprises two oppositely disposedbolt members 38 having their inner ends 39 arranged in parallel spaced position with their confronting faces formed as racks Mi, between which racks is positioned a pinion M mounted upon a spindle 42 which extends above the housing and carries afinger grasp 43.

Each of the end bolt portions comprises, in addition. to.the.housing v35, slidablebolt memcarries a ring 31.

bers 43 arranged to be normally expelled into locking position bycompression Springs 44. The inner ends of each of the bolts 33 are connected bylinks 55 to the outer ends of the bolts respectively, and the lengths of these links lii will be varied depending on the width of each particular sash in the same manner as the lengths of the associated housing parts 31. Conveniently, the centrally positioned operating device can include acam 51 mounted on the spindle i2 adapted to frictionally engage aflexible cord 53, one end of which extends above thehousing 35 and The inner end of thecord 58 is Wound upon areel 59 controlled by a spiral spring 5%] operating normally to maintain the cord in retracted wound position on thereel 59.

When the spindle G2 has been rotated to retract bolts 43- 53, thecord 48 is released by the rotation of cam ll and can be withdrawn to any desired length. Thereafter, the release of spindle 42 will force cam ll back into locking position on the cord and thering 37 can, when the sash has been pivoted inwardly, be looped as over a pin carried by the other sash, thus holding the pivoted sash in any desired tilted position as indicated in Fig. 12.

Modified forms of devices for controlling the position of the pivoted sash are illustrated in Figs. 19 to 23.

In the form illustrated in Fig. 19 folding pivotedarms 52 are pivoted as byscrew 53 within a slot provided therefor in the end bolt housing while the free end of this pivoted spacing member is adapted to be secured between spaced ears 54-55 secured to the slide member 3. A convenient device for removably securing thisarm 52 is shown in Fig. 21, in which apin 55 has a fixedwasher 55 and is normally held in engagement with both of the ears E l-54 bycompression spring 51. By liftingpin 55 against the pressure ofspring 57 the lower end is brought above lower ear 5 andarm 52, thus releasing the spacing member.

In the form illustrated in Fig. 22, the folding arms 52'52' are pivoted within aslot 58 formed in one edge of the sash and the free end of this spacing arm is provided with ahook 59 which can engage a pin 5i on theslide 6.

Various modifications of the various parts will readily suggest themselves to those skilled in the art but all within the scope of the present invention as claimed.
