WEATHER STRIP Filed May 15, 195e Jyz 0 f ve; JOL/ M X ATTORN 52 Patented Dec. 7, 1937 UNITE STATES PATENT OFFICE Application May 13, 1936, Serial No. 79,517
2 Claims.
This invention relates in general to protective devices, and more particularly to an improved interlocking type of Weatherstrip for use on opposing closure members adapted for movement relative to each other.
A principal object of the invention is the provision of means forming a part of the weatherstrip for positively preventing leakage of air or water between the strip and the member to which it is secured.
Another important object of the invention is the provision of a weatherstrip particularly adaptable for use between the sill and lower sash of a window which will effectively prevent the leakage of air therebetween while allowing water to drain 01T the sill therethrough.
A further important object of the invention is the provision of means forming a part of such a weatherstrip which will prevent dry rot of the sill.
Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, when taken in connection with the accompanying drawing, discloses a preferred embodiment thereof.
In the drawing,
Figure l is a vertical sectional view, with parts broken away, of a double hung window equipped with weatherstrips embodying the features of the instant invention;
Fig. 2 is a detail top plan view of the sill rib strip;
Fig. 3 is an exploded vertical section of the sill strip and the female strip co-operating therewith; and
Fig. 4 is an enlarged detail vertical sectional view of a part of the sill strip construction.
Referring more particularly to the drawing, the instant invention is shown as applied to a double hung wood window, but it will be readily understood that it may be applied to any other opposing closure members adapted for movement relative to each other. The window construction herein disclosed comprises the usual sill i I, frame I2, including parting bead I3, and upper and lower sash members I4 and I5, respectively. The lower meeting rail I6 of the upper sash IA has a female weatherstrip member I'! attached to its inside face adjacent the lower portion thereof (Fig. l). The upper meeting rail |8 of the lower sash I5 iscut away at I9 along the lower edge of its inner face and has a male weatherstrip member 2| secured to said inner face so as to engage Within the female member I when the sash are in closed position, as shown in Fig. 1. The lower edges of the members I1 and 2| are bent back upon themselves to provide lower portions having substantially U-shaped cross-sections, such lower portion of the male member 2| tting tightly within the lower portion of the female member I'l, and the two portions taking up the major part of the space provided by the cut away portion I9 of the meeting rail I8 of the lower sash I5.
The upper edges of each of the weatherstrips and 2| are bent at right angles to the plane of the main portions thereof to provide sideward projections 22. The strips I'I and 2| are secured to their respective meeting rails by nails 23 which are preferably spaced a very short distance apart.V 'Ihe weatherstrips II and 2| are made of Zinc, or any other suitable material, and the nails 23 are preferably cadmium plated.
As the strips Il and 2| are nailed to the parting rails, their projections 22 will be forced or embedded into the parting rails to form a positively leak-proof connection therewith. In similar weatherstrips of the prior art, which were not provided with the projections 22, it was impossible to prevent a certain amount of leakage between the strip and the member upon which it was mounted, since those portions of the strip: between the nails 23 could not be tightly secured against the supporting member. With the instant construction, however, this diculty is clearly obviated.
The sill has secured thereto an upstanding rib member or male weatherstrip 2,4 (Fig. 1) which has outer and inner base flanges 25 and 26, respectively, (Fig. 3) formed integrally with the upstanding central portion, comprising a substantially vertical inner wall 2l and a curved outer wall 28. 'Ihe free edge of the inner flange 26 is bent to provide a downwardly extending projection 29 which is similar to the projections 22 on the strips I'I and 2|. At the bends or junctions between the base flange 25 and the curved wall 28, and the flange 26 and wall 2'I, respectively, the strip 24 is provided with a plurality of longitudinally spaced apertures or weep holes 3| and 32, respectively. As is shown in Fig. 2, the weep holes 3| and 32 are spaced alternately with respect to each other. The purpose of these apertures will be explained hereinafter.
A protective base plate 33 is adapted to be positioned on the sill below the flanges 25 and 2B of the rib strip 24, the inner edge thereof abutting against the projection 29, and the outer edge being bent back upon itself at 34 to provide a U-shaped portion within which the outer edge of the ange 25 engages. In the mounting of this part of the device, the members 24 and 33 are positioned together, as above described, and secured to the sill by means of nails 35. As these members are nailed down, the projection 29 of the inner flange 26 will be forced into the sill to effectively prevent any leakage between the sill and the plate 33, as will be seen from Fig. 1.
The inner face of the bottom rail 36 of the lower sash I5 is cut away at 31 along its lower edge (Fig. 1) to provide a space within which the rib portion of the strip 24 engages when the sash is in lowered position. A spring liner strip 38 is secured by nails 39 to the inner face of the bottom rail 36. The strip 33 is Vsubstantially h-shaped in cross section (Fig. 3), having a vertical outer wall 4| with its upperedge bent sharply back upon itself at 42 and its lower portion similarly bent back upwardly upon itself at 43 and extending inwardly and down again to provide an inner vertical wall portion 44. The inner wall 44 terminates vat its lower edge in a curved flanged portion 45, and is spaced from the vertical portion 43 a distance substantially equal to that between the outer surface of the upper portions of the walls 21 and 28 of the rib strip 24. The base plate 33 and the spring strip 4| are preferably made of bronze, and the rib strip 24 of brass, but any other suitable materials may be employed.
In securing the liner strip 38 to the bottom rail 36, the nails 39 are driven through the strip adjacent the lower end of the turned back flange 42 to insure a spring tension in the strip urging the lower portion thereof inwardly. The lower` portion 43, 44 of the strip is positioned within the recess formed by the cut away portion 31 of the bottom rail 36, and the curved ange 45 closely engages the lower corner of the bottom rail, the latter being rounded if desired to insure a better t. The inner face of the bottom rail 36 may also be slightly recessed above the cut away portion 31, if desired, so that the outer surface of the outer wall portion 4| of the strip 3B may normally lie substantially in the plane of said inner face.
The outer wall 28 of the rib strip 24 is curved outwardly at such a point that the lower edge of the bent back portion 43 of the liner strip 38 will engage such curved portion of the wall 28 and be bent outwardly thereby a slight amount when the sash l5 is lowered into its position of Fig. l. This will insure a tight leak-proof engagement between the male portion of the rib strip 24 and the female portion of the liner strip 38. In this lower position of the sash l5, the curved flange 45 of the liner strip 38 will substantially, but not quite, close the inner weep holes 32 in the rib strip 24, as will be clearly apparent from the magnified showing of Fig. 4. With this arrangement, any water or moisture, such as that resulting from condensation on the inner surface of the window, will be Vallowed to drain through the weep holes 32 and 3| of the weatherstrip 24. The base plate 33 will prevent such moisture from coming in contact with the sill under the rib strip 24, and will thus protect this portion of the sill from dry rot.
At the same time, due to the alternate spacing of the small apertures 3| and 32, any air movement through the rib strip 24 will be effectively prevented. If it is desired, of course, the several parts may be so proportioned that the curved flange 45 will completely close the weep holes 32 when the sash I5 is in its lowermost position to positively prevent any air leakage between the strips 24 and 38.
It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
We claim:
1. The combination with a window frame having a sill and a sash movable relative thereto, of a rigid rib strip secured to said sill and having a plurality of weep holes therein, and a liner strip secured to said sash and provided with a flange portion adapted to substantially close certain of said weep holes when said sash is moved to closed position to permit water to drain between said sill and said sash while effectively preventing air leakage therebetween and a second flange portion adapted to resiliently engage one surface of said rigid rib strip to provide an effective seal therebetween.
2. The combination with a window frame having a sill and a sash movable relative thereto, of a rib strip secured to said sill and having weep holes therein to allow water to drain therethrough, and a liner strip having a substantially h-shaped cross section secured to said sash with one of its lower anges adapted to close certain of said weep holes when said sash is moved to closed position, and the other of its lower anges adapted to resiliently engage said rib strip to effectively seal the space between said sash and said sill.
