LE ON E.-KLEIN, OF LOS ANGELES, CALIFORNIA v WE T ER GUARD non CASEMENT wnvnows Application filed April 30, 1928: Serial No'. 273,791.

This invention relates to closures for Windows. and the like and" more particularly to weather strips for sealing windows of the casement type, which as is well understood '5 are hinged to the window frame at one side.

*Heretofore it has been common to swing casement windows outwardv in order that, i when closed, the window could co-operate with the sill to form a proper guard for exeluding wind and rain. Where such windows were hung to swing inward a satisfactory'seal" was rarely if ever produced.

The primary object of the present invention is to providea guard for windows, which 1 guard is especially'a'dapted to be used with windows hung toswing inward and which at the sametimewill serve effectually to exclude the weather. A further object is to provide such a guard which will be automatically 2 0 actuable to and from operative position'as the window is closed and opened.

' Stated briefly, the invention resides in the combination of a window frame having a sill: and a window sashhinged to the frame F at one side, with a guard rail mounted on the sill and adapted to enter a groove extending longitudinally in the lower edge of the bottom bar of the sash, the groove in the bar being wider near the hinged edge of the sash than at the free: end in order that suflicient clearance "will beprovided to avoid premature actuation of the guard. railby permitting the saslrtobe moved almost to closed po= sition before engagement of said rail'by the I free or outer end of thegroove wall causing the 'rail'to be urged toward operative or upright sealing position. The under edge of the outerside of the bar formingthe groove is slightly tapered at the end on the hinged side forthe purposeof insuring depression of the rail and avoid amming when the window starts toswing to closed position; The" in vention also resides in such other novelfeatures OfCOIlStIUCtlOIl. and arrangement as may 4 beherein. presented- In the accompanying drawings wherein oneform of the invention is disclosed by way I of illustration; v

' Fig. 1, is an insideelevation of a window frame in which arehung two casement windows constructed to co-operate respectively with two weather guards according to this improvement, the windows being shown in open position and the guards in corresponding or lowered position.

Fig. 2, is partially a horizontal section and partially a plan as viewed from the line 22 of Fig. 1;

Fig. 3, is'a vertical section taken from line 3 -3-of Fig. 1.

Fig, 4, is chiefly an'elevation of the structure of Fig. 1-, the windows being closed.

Figs. 5 and 6, are fragmentary sections taken respectively on thel-ines 55 and 6-6 of Fig. 4, showing the relation of the guard rail to the groove at the outer and inner ends thereof respectively, when the window is closed; in Fig. 6', the position of the guard rail in the inner end of the groove ust before commei-icing the last portion of the closing operation, is indicated in dotted lines.

F ig'. 7, is a similar view taken at the position of the line 55 showing the relation of the guard rail and the outer end of the groove just when the window isin position to commence to move t he guard rail to upright or closed position, this closed position being represented in dotted lines and corresponding to the position shownin Fig. 5.

Fig. 8 is a fragmentary horizontal section taken on l-ineS-Sof Fig. 4, the window being closed.

According to these drawings, a window frame 10 having an outer sill 12 andan inner sil l 14, is'provided with two casement windows whose sashes 15 are hingedthereto at 16, the lower bar of each sash co-operating with a movable guardrail 20 hinged at 22 to the outer edge of; the outer sloping portion 14 of the sill 14, swinging movement of the rail being permitted by bevelling the under side at 23. Each lower sash bar 15' is provided on its under side with a longitudinally extending groove 24 which forms an outwardly facing vertical wall 25 lying alongside the rail 20 when in operative position. However, the outer portion of the bar 15 opposite said wall 25am on. the outer side 26 whose under edge preferably is beveled transversely at 27 toco-operate with a correspondingly beveled face on the rail 20 for proper exclusion of rain and the like. Thus,

It is tocbe noted particularlythat, since the inner end of eachbar 15 (that end near the hinged side of the sash) moves almost to closed position much earlier inthe closing movement than does the outer or free end of the bar, the inner end of the groove 24 must be formed so as not to actuatethe guard rail 20 before the outer end of the bar has nearly reached closed position. Otherwise, the wall 25 of said groove would begin to swing the rail 20 into closedposition before its entire length could enter the groove, in which case the upper edge of the rail would jam against the lower edge of the lip 26. Therefore it is necessary. that the inner end of the groove be wider with respect to the thickness of the rail than theouter end and that this extra width be sufficient to accome inodate the'difierential of movement. This is accomplished by extending the wall 25 of said groove at an angle as best seen in Figs. 2 and 8, whereby the groove is tapered and gradualiy widens, the outer wall of the groove forming-the innerface of lip'26 being par allel with the outer walls of thebar.

The relation of these parts invarious positions is illustrated best in Figs. 5, 6 and 7, wherein Fig. 5, shows the relation'of the parts at the outer end of the rail and groove, the parts being in closed or operative position. In Fig. 6, the relation of the parts in the same position at the outer end of the groove is shown in full lines, while the position of the rail 20 inthe groove just before the rail swung toward closed position, the rail being I in open or dropped position as in Figs. 3 and 7 the lip 26 at the inner end passesover the rail and the extra width of the groove;24 at said inner end prevents engagement of the wall25 with the rail until the outer end of the wall 25 has reached the full-line position of Fig. 7 whereuponsaidwall 25 then causes the rail to swing upward and outward from the position of Fig. 7 and to pass into the groove and thus into, sealing position as seen in Figs. 5 and 6. In order that depression of the rail 20 into the open position of Figs.

1, 3 and 7, may berinsured to avoid binding or jamming of the parts, the under edges'of the innerend of lip 26 is slightly: beveled uphinged side.

Ward at 26 as indicated in Fig. 1, this bevel first passing over the upper edge of the inner end of the rail, and, if the same is up a little too far, forcing the rail downward so that the rest of the under edge of said lip may pass freely along and over the upper edge of the rail.

The parts now being in the closed position, an effective weather seal is provided, the shedding of rain and the like being insured by the beveled faces 27 and 28'and also by the under beveled face 23, and wind and dust being excluded by the generally tight joints between the parts.- lObviously, the thickness same, the width of the groove being uniform,

Y or both rail and groove may be tapered, either of these variations providing the required play at the inner end of the groove and rail.

I claim: r

1. In combination, a swinging casement window having a transverse bottom bar, a sill co-operating therewith, and a transverse rail hinged to said sill, said bar having a longitudinally extending grooveadapted to re ceive said rail as the window is swung to closed position, one end of the groove being wider than the other. 7 a

V 2. In combination, awindow frame having a sill at its lower end, a window sash hingedto one side of said frame and, having a lower bar, a transverse rail swingingly' mounted on said sill and having an upstanding lip, said bar having a longitudinally extending groove in its lower edge to receive. said lip, the width of said groove with rela tion to said lip being greater at the mounted side of the sash than at thefree side, and a r flange depending from said bar andextendingbelow the upper edgewof said lip regardless of the position of the rail, whereby said flange will engage and swing the railinto operative position. j x V 3. A structure according to claim 1, wherein the lower edge offthe portion of the bar which passes over the railis beveled upwardly at the end next to the mounted'side of the sash in order'to' insure depression of the rail I as thesash swings to closed position.
