Sepia 9 1950 STORM WINDOWS v ma, v M WM I l WW1 if INVENTOR. CV/ffora/Z. 14/ 6 Patented Sept. 1950 This invention relates to storm}windowsinl departing-from the spirit offthe invengeneral and in particular to means for locking the meeting rails of a double hung storm window as; sembly to one another.

The principal object of the invention is the provision of a device for holding the meeting rails of a double hung storm window assembly in engagement with one another.

A further object, of the invention: the it -f vision of a device engageable in one of the'meet ing rails of thedouble hungistorm window assembly for joining the meeting rails of the said window assembly when in closed position. v I A stillfurther object of the invention is the provision of an extruded metal-part engageable in a metallic sash for. self retention therein and having means thereon for engaging an adjacent; metallic sash and urging. the-same toward the first mentioned sash. i

The meeting rail engaging member forstorjm windows shown and described herein comprises a;

simple and efficient meansfor securing metallic framed storm window sash to one another and particularly the meeting rails'thereof which have heretofore presented a problem in storm window construction. a 1

As is known in the art, relatively lightweight .metal extrusions are commonly employed as glass :frames to form storm window sash and such :storm window sash are commonly'positioned vin :a mounting frame in double hung relation for vertical sliding motion therein. -The sides 'a'nd top and bottom portions of the'sash which enigage the frame are thus secured in an air-tight manner. 1 ,1:

. The meeting rails of the sash are normally positioned adjacent one another and heretofore have not been secured to one another with the result that wind pressure or deflection of the sash themselves separated the meeting rails and destroyed the effectiveness of the storm window assembly. The present invention eliminates this difficulty as it causes the meeting rails to move into close engagement with one another and provides tension therebetween thus enabling each of the meeting rails to support the other and at the same time maintain themselves in desirable face to face engagement.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed tion..

{The invention isillustrated in the accompanying drawing, whereinn 5 Figure 1 is a vertical section of a portion of the tmeeting rails of a pair of double hung storm window sash.

Figure 2 is a vertical section of a portion of the meeting rails of a pair of double hung storm '10 windowsash in open position. I

(iii v.liiigure is plan view of a portion of the meeting rails 9f apair of' d ouble hung storm window a h lig nre 4 is a perspective elevation of the meetmg rail engaging member.

2 in particular it will'be seen that portions of a pair; of double hung storm windowsash have been disclosed the transparent pane of the upper o uter.;;sash beinggindicatedby thenumeral II] m and its meeting rail metallic frame on. its" lower edge;being indicated by the numeral III. The transparent pane of the inner lower sash is indicated by thenurneral I2 and the metallic meeting rail thereof ,is indicated by the numeral I3.

The transparentpanes II] and I2 are secured at themeeting rails II and I3 b y;metallic splines I4 and, I5, respectively, asis customary in storm window practice. In Figure 1", Qfthe drawings the meeting rails. II. and l3,-.;respectively, are shownin faceto face engagement which is their normal position when thestormwindow'is closed. In Figure,.2 of the drawings the meeting rails II and ISar'e shown in disengaged relation as is the case Whenthelower inner pane i2 is elevated or the upper outerpane Ill lowered.

Still referring to Figures 1. and 2 of the drawings it will be observed that the upper edge of the meeting rail I3, which is positioned on the upper edge of the pane. I2 of the lower inner sash, has a relatively short section of an engaging member Ifi slidably engaged therein and preferably positioned in the center thereof with respect to the sides thereof (not shown). The engaging member I6 comprises an extruded metal shape, the body portion of which registers within a channel I! of the meeting rail I3 and par-' tially beneath a flange I8 thereof. The body portion of the engaging member I6 is formed to overlie the upper edges of the meeting rail I3 by reason of a pair of flanges I9 and 20, the flange I9 being relatively short and the flange 20 extending outwardly and having its outermost, lowermost edge slightly outturned as indicated by the numeral 2|.

The engaging member I6 is shown in perspec- By referring to the drawings and Figures land 3 tive in Figure 4 but it will be observed by referring thereto that its cross sectional shape is such that it will register with the channel I! of the meeting rail l3 and thereby enable the same to be slid into position longitudinally thereof atfthe-timeof formation of the storm sash, and'to be self retaining therein. In position, as shown in Figures 1, 2 and 3 of the drawings, the engaging member I6 lies midway between the sides of the sash so that the depending flange 20 will slidably engage and tension a spline receiving channel 22 formed in the upper edge of the meeting rail II which is on the lower edge of the transparent pane [0. The action of the engaging member is illustrated in Figures 1 and 2' of the drawings.

In Figure 2 of the drawings the sash are shown her and the channeled part interfitting with each other to form an interlocking connection between said member and said channeled part, the body part of said member having a laterally extending portion overlying the upper edge of the straight inner side wall portion of the last mentioned channeled part, and a flange extending downwardly from said laterally extending portion to fit against the inner side of the straight inner sid wall portion of the channeled part of the meeting rail of the upper sash.

2. A double hung storm window assembly comprising upper and lower vertically slidable sashes in disengaged or partly open position with the meeting rails out of engagement. In Figure 1 of the drawings the sash ar shown in engaged or fully closed position, it being observed that the meeting rails H and 13 are in face to face engagement and held in that engagement by the tensioning action of the engaging member 16 and specifically the depending flange 20 thereof which engages the meeting rail ll.

Itwill thus be seen that a simple and efficient device has been disclosed which may be inex pensively formed and easily applied to storm window constructions and particularly those 'employing metallic frames such as shown herein. It Will also be seen that in operation the engaging member will efiicie'ntly hold the meeting rails of the storm window sash in tight face to-face engagenient whereby they become self-supporting and whereby any possibility of air leakage at this point of the storm window construction is eliminated.-

Having thus described my invention, what I claim is:

1. A double hung storm window comprising upper and lower vertically slidable sashes each including a metal frame, the meeting rails of the;

close fitting engagement with the straight side wall portions of said channeled part, said memeach including a metal frame, the meeting rails of the frames of the sashes each comprising an upwardly facing channeled part, and the channeled parts of the meeting rails having straight inner side Wall portions to fit one against the other when the sashes are in closed position, the straight inner side wall portion of the channeled I part of the meeting rail of the lower sash having at its upper edge a flange extending laterally to the inner side thereof, and a member for holding the meeting rails of the sashes in engagement with each other when the same are in closed position, said member comprising a main longitudinally ext-endingbody parthaving at one side .at its upper part a longitudinally extending shouldered portion, said body part fitting into the channeled part ofthe meeting rail of the lower sash withits shouldered portion in interlocking engagement with the laterally extending flange on said side wall portion, and said body a part having a laterally extending portion overlying the upper edge of said straight side wall portion, and a flange extending downwardly from said laterally extending portion to fit against the inner side of the straight inner side wall portion of the channeled part of the meeting, rail of the upper sash.
