* 'G. F. NORDBLAD WEATHER STRIP Filed. Aug. 28,' 1916 I Patente Apr. 1, 123.
GU'NNAR- F. NORDBL, OF CHICAGO, ILLINOIS, ASSIGNOE 1'0 ROBERT M. BURNS, ('JE CHICAGO, ILLINOIS.
/ THEE STRIP.
Application filed August 28, 1916. Serial No. 117,141.
To all whom it may concern Be it known that I, GUNNAR F. NoRoBLAD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Weather Strips, of which the following is a specification.
This invention relates to weather strips, and several of its objects are to provide a very effective closure against dust and air currents without making incisions or kerfs in the slideways for a window sash or in the sash itself; to provide a weather strip which serves to hold the dividing or parting strip between upper and lower sashes in place, and to utilize this dividing strip as the sole groove-bearing member which simplifies the grooving for metal weather strips, makes the part to be grooved for this purpose very easily accessible to the mechanic and easily accessible in case of any disarrangement of the groove and strip engagement by reason of the entrance of foreign substances, or otherwise. A still further object of the invention is to provide a weather strip of metal which provides a metal slide surface that facilitates the raising or lowering of a sash and tends to prevent its binding in its slideways when the power is applied to a point near one corner of the sash. A still further object of the invention is to provide a metal weather strip' which does not interfere with the sash cord arrangement and which extends its continuous weather-proofing to the top of the window frame past the opening for the sash cord pulleys.
With these general objects in view my invention consists in the novel construction, combination and arrangement of parts, hereinafter described in detail, illustrated in the drawing and incorporatedin the appended claims.
In the drawing- Figure 1 is an elevation of a window frame with upper and lower sashes, the latterpartly broken away, equipped with my improvement.
Figure 2 is an enlarged section through both sashes and the window frame.
Figure 3 is a similar view with the upper and lower sash spaced apart from the frame and the weather stripping on the sashes separated from the co-operating weather strip tions. 9 and 10 are the usual inner stops and 11 is the upper horizontal dividing strip in the plane of the side dividing strips represented at the left in Figure 1 by the numerals 5 and 7 and at the right by the numerals 6 and 8.
As will be noted by reference to Figures 2 and 3 all of the weatherproofing is done between the upper and lower sashes and in the dividing strip, and the weather stripping holds the dividing strip in its retaining groove 11 against accidental displacement therefrom. The dividing strip at either side is represented by the numeral 6 in Figures 2 and 3 and the junction lines where the upper and lower sections of the dividing strips meet are indicated in Figure 1 at 12 and 13.
A groove 14 extends the entire length of the dividing strip, and in this groove 14 is mounted a W-shaped cross section strip 16 the edges of which terminate in flanges 17 and 18 which form facingsfor the dividing strip. This W-form strip provides a deep groove or channel 19 that is engaged by a U-shaped flange or leg 20 on a U-shaped window sash strip 21 one leg of which is placed between the sash and the dividing strip and bears a flange 22 that is fastened by means of a suitable number of screws 23, through holes 24 in the flange, to the slide-way edge or side of the upper window sash frame. The other leg of said U-shaped strip 21 engages one of the grooves or chan- When the latter is in place its exterior outlines conform as snugly as possible with the interior outlines of the groove 19 or 25, each of which is a little wider at its bottom than at its opening or inlet. There is suficient flexibility in the two-ply dividing wall 26 to permit the enlarged edge of the flange or leg 20 to be forced through the contracted outer part or opening into the groove 19 or 25. The flange 22 in the case of both the upper and the lower sashes is preferably let into the side rail of the sash to the extent of a shallow rabbet 27 to make the outer surface of the flange 22 flush with the surface of the sash rail, though this is not essential, and may not be preferred where the sashes fit loosely in the window frames. The flanged W-shaped strips for the two sides of the window frame are in four sections meeting at the lines 12 and 13 in order to make convenient the removal of the sashes from the frame. To accomplish such removal of the sashes after the stops 9 and 10 have been removed in the usual way, the upper dividing strip sections 5 and 6 may be removed when the upper sash is lowered to the same level as the lower sash. The lower dividing strip sections 7 and 8 may then be removed after first raising both the upper and lower sash to the normal position of the upper sash. In other words by simply pulling out the dividing strips the interengagement of the weather-proofing strips is released. The double groove channel strip 16 may be held in its groove 14 by friction or spring engagement alone, but it is shown fastened by small nails 28 to the bottom of the groove 14.
By reference to Figure 2 it will be noted that the sash strips and dividing strip metal strips provide metal rails or slide-ways which tend to make the operation of the sash smooth, free from binding and comparatively free from the heavier wood to wood friction engagement which is often very troublesome particularly when the wood is wet or somewhat swelled by moisture. Save for what appears on the exposed or outer face of the dividing strip my improved weather stripping is invisible, the metal on the sash being substantially covered, or concealed, by the dividing strip.
So far as I am aware my improved weather strip is the only one of those found adapted for practical use, or which are to be found in the market, which has a construction that makes it unnecessary to nail or fasten weather stripping to the window frame which nailing entails the loss of a great deal of time when the sash are to be removed, In applying my improvement already prepared parting or dividing strips may be provided in the standard sizes and the strips that are removed taken to the factory to be grooved and metal shod for later weather stripping jobs.
I claim as my invention l. The combination with a window sash and a grooved dividing strip, of metal weather-stripping which consists of a transversely bent strip of metal which occupies the groove in the dividing strip and forms two channels with a two-pl dividing wall 2(3therebetween, and a strlp of metal U- shaped in cross-section that is secured to the sash and has one of its legs slidable in one of the channels while the other leg is disposed between the sash and one side of said dividing strip.
2. The combination with upper and lower sashes and a frame in which they; are slidable, of a grooved dividing-strip, and a transversely bent weather-strip mounted in the groove of the dividing-strip and forming a pair of channels with a dividing Wall therebetween, and a strip attached to each of the sash-frames, each of said strips being bent to provide a flange which slidably engages one of the grooves and to provide a part which is disposed between its respective sash and one of the sides of said dividing-strip.
3. .The combination with a window-sash and a grooved dividing-strip, of a doublechanneled n'ietal-strip mounted in said dividing-strip groove, and a U-shaped metalstrip with a. leg placed between the side of the window-sash frame and the dividingstrip, and having the other leg slidably engaged with a channel of said double-channeled metal-strip.
4. The (ombination with an upper and a lower sash and a window-frame in which said sashes slide, of a grooved dividing-strip between said sashes, a metal strip substantially W-form in cross section and seated in said groove, said W-form metal strip containing a pair of grooves and metal strips secured to said upper and lower sashes which have flanges that move in said grooves and also flanges that are disposed between said sashes and the sides of said dividing strip.
5. In combination with upper and lower window sashes, a joint closure comprising a parting strip having a longitudinal groove therein, and a weather strip transversely bent to provide a pair of channels with a dividing wall therebetween, the channelforming portions of said strip being disposed in said groove, and U-shaped strips having respectively laterally extending flanges attached to the side edges of said sashes. with one leg of each U-shaped strip engaging the faceof its respective sash, and the second leg slidably engaging in its respective channel.
In testimony whereof I have hereunto signed my name.
GUNNAB F. NORDBLAD.
