WEATHER STRIP.

APPLICATION HLED JAN. 26. m4.

Patented Apr. 6, 1915.

"km w? ALFRED M. LANE, OF ST. LOUIS, MISSOURI, ASSIGEQR T0 MONABCHMETAL WEATHER STBI? COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION 01 MISSOURI.

WEATHER-swam 1 '0 all whom it may concern lie it known that I. dunno M. LANE, a citizen of the luliteil States, and a resident of the city of St. Louis and State of Missouri .havc invented a new and useful lmprovement in \l'eathcr-Strips, of which the following is a specification.

Thisinventlon relates to weather strips and more particularly to that form of weather strip which is especially adapted to by any swelling or shrinking of the window' sash or by any other derangement of the relative position of the sash and frame whether due to wear and usage or any other cause, and which will prevent any rattling of the sash.

Other objects of my invention and advantages resulting from the construction I employ will more fully appear hereinafter. In general, according to my invent on, the

members forming the weather strip are made of thin resilient sheet metal,.pref-- erably of some suitable non-corrosive material, and each member is adapted for attachment to one of twomeeting parts, such as the frame and sash of .a window. One member is formed with a, sealing tongue, which, in the closed position of the \VlIlClOW,

' engages in a receiving pocket formed as 'a part of the other member and the mouth edges of this pocket are held by the resilicncv of the parts in close contact with the sealing tongue.

The invention consists in the construction and in the arrangement and combination of parts hereinafter more fully set fartin In the accompanying draw1ng,'- whichforms part of this specification and iniwhich like reference characters refer to like; parts throughout the diifereut views, Figure l is across-section of a weather strip embodying Specification of Letters Patent.

Application filed January 273, 1914. Serial No. 814,297.

frame and sash being shown in horizontal section, and the window being partly opened; Fig. 2 is a view similar to F ig.. 1, the window being closed; 3 is a view of a weather strip embodying a modified form of my invention showing it applied to the bottom of a casement window,,the casement window frame and sash being shown in ver tical section and the window being partly opened; Fig. a is a view similar to Fig. 3, the window being closed; Fig. 5 is a crossscction of a weather strip embodying another form of my invention showing it applied to the meeting stiles of a pair of casement window sashes, one window being partly opened; and Fig. 6 is a view similar to Fig.5 with the window closed.

In the drawing, a portionof the window frame is shown and is designated by the glnal portion of the member A is bent upon itself so as to form a pocket 5, the free edge of which is bent to form a roll orbead 6,

which normally lies in contact or nearly in contact with the main body of the member.

The window sash 7 is rabbeted to accommodate the other member B of the weather stri and this member B cooperates with thememberA to form the weather-tight joint. The member B extends along the windowsash 7 and one marginal portion 8, reinforced by a sharp rebend, is tacked or otherwise suitably fastened to the face of the'rabbet adjacent the vertical face of the sash. From this marginal portion Sthe ;member is bent to extend into the rabbet and rebent to form a groove 9; and the remaining portion is rebent sharply along the outer edge of the groove 9' to form' a sealing tongue 10 and is thence extended: along the outer face of the sash, to

asoo sternum Q it is fastened by tacks or by any other suitable fastening means.

the window is closed, the sealing tongue 10 of the member B engages the inwardly bent portion 3 of the member A and de presses the 'main body of the member A. This guides the sealing tongue-10 between the body of the member A and the bead 6 into thepocket- 5. The bead 6 engages the bottom of the groove 9. The joint formed in this construction is characterized by three lines of contact between the members. The mouth edges of the pocket 5 press resiliently upon both faces of the sealing tongue 10 and thus form two lines of contact. The bead 6 seats tightlv against the bottom of the groove 9 and forms the third line of contact.

Under normal conditions the portion 3 of the member A extends away from the frame 1 toward the window sash to such a. degree that, when the window is closed, the portion 3 is pressed back toward the frame and is thereby placed under tension so as to bear firmly against the outer face of the sealing tongue 10. This not only makes the joint tight the pressure against the outer face of the sealing tongue 10, but also prevents the window from rattling. In many cases the fit of the window sash 'in its frame is affected either by shrinking, swelling or warping of its parts or by'wear.; and the window sash has the position of its top, bottom or sides or of some intermediate part displaced relative to the frame so that there is not. the normal space between the frame and these parts.

In my invention, any part of the member- B may move either toward or away from the frame 1 to a large extent and still the sealing tongue 10 will be guided into the pocket 5. This insures that the members A and B will always be placed in their operative position whenthe window is closed regardless of the fit of the window sash in its frame. Also, the jointformed by the members A and B is not affected-by the position of the window sash 7 relative to the frame 1' and the same three lines of contact are maintained. This will be understood from an eX-' amination of Fig. 2. As the window sash 7 moves away from or toward the frame 1 the sealing tongue 10 will always maintain two lines of contact with the mouth edges of the pocket 5, and the head 6 will rock in its seat at the bottom of the groove 9 and maintain the third line of contact. -The member'A'is placed so as to make the joint which it forms with the member B at the outer or weather edge of the window so as to prevent the out side air, moisture or dust from even partially entering. In Weather strips, the joint between the parts not only serves to protect against moisture, but also acts to receive and partially retain moisture; and to protect all the exposed wood against he attack of ins-sacs as to cover the faces of the rabbet in the sash.

my weather strip is installed, the members A and B are extended around the top and sides of the window; and it is possible that some moisture, cold air, or weather elements may pass downwardly along the sides of the window. Q I

For the bottom of the window the moditied form of weather strip shown in F3 and 41 is especially adapted- In this moditie-d :iorm, the member A is-mountcd in. a r; bet in the window sash 7. One marginal portion 11 of the member A, reinforced by a sharp rebend, is tacked to the window sash. From this marginal portion 11 the major part is bent to form an arch 12 extending away from the face of the rabbet. From the line of contact of the freeedge of this arch with the face? of the rabbet he member A is thence extended and bent upon itself to form a pocket 13 having its free edge rolled to form a bead it. The member B is substantially "sf-shaped and one part 15 is tacked or otherwise suitably secured to the window sill 1 From this part 15 the rnemher is extended upwardly and then outwardly, substantially parallel with the top face of the sill l, to form the horizontally According to the preferred way in which I farther from the outside or weather edge of the window than the joint formed at the sides and top,of the sash which is shown in Fig. 2. This'assures that all of the cold air, moisture, or other weather elements that may pass downwardly along the sides of the window sill be guided outside of the joint at the bottom. The window sill 1 is cut away to form a face 17 slanting downwardly from the outer edge of the attached part 15 of the member 13; to drain away'any moisture which may accu- This serves not only mulate at the bottom joint of the window,

but also makes it necessary for any moisture which may reach the bottom joint'to pass upwardly along this downwardly extending incline. i 1

- The form of weather strip illustrated in Figs. 5 and 6 is specially adapted for use in connection with the meeting stiles of case-- "mcnt windows. The

casement window sashes l8 and 19 are usually provided with matched

rabbets

20 and 21 respectively. A pocket member A", substantially the same in form as the pocket member A. shown in forccmcnt.

master sirable will not accommodate such a rein-' The tongue member BVis the 'SIIHQ as the tongue member B shown in Figs. 1 and 2 and is similarly disposed in the rab bet 23 in the faceof the-stile 19. The marginal edge 2% of the member 13', is tacked to the outer face of the stile l9 and the reinforced marginal edge 25 is tacked to the vertical face of the rabbet 23.

Obviously, the diiferent forms of invention are not limited'in their use to the particular parts of the Window to which I have shown and described themas being applied, and while I have shown my invention in connection with a casement window, it may, if desired,'be also applied to the horizontal meeting rails of sliding-window sashes-or to any other construction where the conditions are favorable. Therefore, I do not Wish to be limited to the particular construction and arrangement that I have shown vand described.
