An object of the invention is to provide a metal parting bead, and improved means employed therewith, for weather proofing windows of metal or wood construction. An

` improvement and advantage of my device lies in the provision of means whereby an effective seal is formed between the sash and frame, even though there be considerable side or end play between these members.

Another object of my invent-ion is to provide means to check side play in window sashes, and to eliminate the rattling noise caused by wind. A

A further object of my invention is to provide a weather strip which permits the sash to be easily removed and replaced without distorting or removing any member of the strip, from its secured position in the window assembly.

A still further object and advantage is attained in the ease and facility with which the weather `proofing of my invention can be installed, since it has been found that an ordinary mechanic is able to equip a window with my device in considerably less time than is required with any of the prevailing types. ther objects and advantages will appear from the following detailed description of a single executional embodiment of my invention and the accompanying drawings thereof, in which Fig. 1 shows a horizontal sectional view through a portion of a window frame and upper and lower sashes, to which my parting member and weather strip has been applied; Fig. 2 is a perspective, phantom view, the purpose of which is to illustrate the position of the biasing member hereinafter described; Fig. 3, a fragmentary perspective view, shows a metal parting bead of prefererd form, and paired weather proofing members in operable disposition and Fig. 4 is a sectional elevation taken on line 4-4 of Fig. 1, and shows a preferred method of securing the parting bead into position.

Referring nowto Fig. 1, upper and lower sashes 5 and 6 are adapted to slide vertically in their respective guideways formed by the pulley stile member 7, the outer bead 8, and the inner bead 9. The pulley stile 7, is provided with a. groove or channel which con- Cil stitutes a seat for a spacing member or parting bead. In the ordinary window construction, the parting bead is of standard width and usually comprises a strip of wood, rectangular in cross section, which runs from the bottom to the top frame members.

I prefer, however, to provide a parting bead 11, of sheet metal. Zinc or copper is well adapted for this purpose, although any non-rusting metal or rust-resisting metal may well be used. My parting bead comprises, essentially, a hollow rectangular member, one wall of which has a narrow, longitudinal opening 12, cut centrally therethrough. The parting bead is adapted to be positioned in the channel 10 with the slotted wall outermost, and preferably secured by means of angulate members such as 13, at the ends thereof. These members, fastened as by screws 14, into the top and bottom frame member, provide a simple expedient for holding the parting bead into the groove, and permit the bead to be easily and quickly removed.

My weather strip comprises, essentially, a sealing member 15, which cooperates, in slidable engagement with member 16, to form a seal in the manner illustrated in Fig. 3. The members 16, which for convenience will be termed slidable members, are fastened to the stiles of the sash, and preferably extend the full length of these members. A plan view of the sliding members reveals a straight portion 17, a bend 18, and curved portion 19. The portion 17 is provided with perforations 20 atsuitable intervals alongl its length, and nails or screws, indicated at 21, extend through these apertures and serve to fasten the sliding members to the sash. The marginal portion is preferably rebent, as shown, thereby protecting the heads of the securing elements and producing a sliding surface of relatively small area.

The sealing member 15, preferably of channeled construction and formed also of sheet metal, includes a corrugated flange 22, a web 23, and a portion 24 which, by preference, is curved to conform with portion 19 of the sliding member 16. It is obvious that the mating portions 19 and 24 may be of any suitable form, but I prefer to make them arcuate,

and thus improve the seal formed therebetween. The corrugated flange 22 is adapted to be disposed within the parting bead and the web 23 extends through the opening 12, in the manner shown. A resilient member 25, preferably in the form of a semi-elliptical spring, is positioned between the front wall of the parting bead and the flange 22 and frictionally retained by means of the corrugations, and permits the sealing member to be moved outwardly of the parting bead, aga-inst the biasing action of the spring. By reason of the spring and semi-floating position of the sealin member, this latter element is constantly he d in contact with the sliding member, and the seal is maintained in spite of sidewise movement or irregularities of the frame. In window constructions, a condition is often encountered where from wear or other reasons, the sash stiles are not parallel to the ulley stiles. It is therefore advisable to m e provision to compensate for this misalignment by permitting, as in the present example, the members to assume a variable angular position, through a range of a few degrees, with respect to the parting bead, which is usually secured in parallel relation to the pulley stiles. Otherwise expressed, the springs 25 are so disposed as to permit dissimilar distance relations to exist, along and between portions of the members 15 and the parting bead.

Although sealing members only slightly in excess of sash length would be suiicient, I prefer to extend these elements the full lengt-h of the window frame, and provide springs at suitable spacings along their len h. B. this arrangement, the Weather proofing is efective regardless of the position of the sash, and all noise caused by the rattling of a loose sash is eliminated.

In installing the Weather stripping of my invention, the members 16 are nailed or screwed to the stiles in the manner shown. The upper or outer sash 5 is put in the trame and retained by means of the parting bead. The parting bead, with sealing members and springs assembled therein, is placed in the groove 10, it being necessary to draw the member 15, outwardly against the action of the springs so as to permit engagement with the sliding member. In like manner, the lower or inside sash is positioned and secured by means of the inside bead 9.

It will thus be obvious to those skilled in the art, that my device affords many advantages over prevailing forms of weather stripping. Many of these employ a metal strip cooperating with a channel cut into the sash or rame and the cutting and fitting of the channel and strip member, demand a consideration amount of the time of a skilled mechanic.

While the aboveV description and the accompanying drawings illustrate a preferred embodiment of my device, I do not wish to limit it to the specilic construction and arrangement of parts shown, as various modiiications and deviations may be made without departing from the full spirit and scope of my invention.
