Description

Sept. 21, 1943. H. D. sEvlsoN BOTTOM RAIL SEALING STRIP Filed July 24, 1941 Patented Sept. 21, 1943 2.329.791 BOTTOM RAIL SEALING STRIP Harry D. Sevison, Elkhart, Ind., assgnor to The Adlake Company, Chicago,
of Illinois Ill., a corporation Application July 24, 1941, Serial No. 403,803
' l 4 claims. (ci. iss-ss) This invention has to do with vertically slidable window sash of the type commonly used in buses and other vehicles, and is particularly concerned with the prevention of leakage beneath the bottom rails of such sash.
The object of the invention is to provide an improved bottom rail sealing strip which will aiiord a double seal with the sill of the window when the sasliJs in its lowermost position, with one seal located inthe usual position beneath the bottom rail in contact with the exposed outer portion of the sill and with the other seal located inwardly of the rst seal .in contact with the elevated inner portion of the sill.
A sealing strip constructed in accordance with the invention will eiectively prevent the entry of water, air, dust and other foreign matter, even though the sill be disposed at such an angle as to vpermit of some accumulation of foreign matter and even though slight irregularities be present in the shape of the sill.
While the foregoing statements are .indicative in a general way of the nature of the invention, other more specic objects and advantages will be apparent to those skilled in the art upon a full understanding of the construction of the improved sealing strip.
A preferred embodiment of the invention, and also two variations, are presented herein by way of exempliilcatio-n, but it will of course be appreciated that the invention is susceptible of incorporation in still other structurally modiied forms coming equally within the scope of the appended claims.
In the accompanying drawing:
Fig. 1 is a perspective view of a short section of the new bottom rail sealing strip Fig. 2 is a somewhat similar perspective view, showing the sealing strip applied to the bottom rail of a sash;
Fig. 3 is a Vertical transverse section through the sill of a. window, showing the manner in which the improved sealing strip is intended to coact with the same in the lowermost position of the sash; and
Figs. 4 and 5 are similar views of two modications.
The sealing strip shown in Figs. 1 to 3 inclusive of the drawing is constructed of soft resilient rubber and is provided along its top with a laterally grooved head portion I for endwise insertion in a partially closed channel II in the lower portion of the bottom rail I2 of a vertically slidable sash, in securely interlockedassociation with the bottom rail. Beneath the head portion I 0 the sealing strip is provided with a downwardly ex- -tending body portion I3 which is adapted to sup- -port the weight of the sash on the sill I4 oi the window when the sash is in its lowermost position.
The body portion I3 of the sealing strip is provided with two oppositely extending nap-like sealing lips I5 and I6. The lip I5 extends forwardly from the lower part of the body portion I3 and curves downwardly in a thinning taper into resiliently yieldable and closely conforming engagement with the exposed outer portion I l of the sill. The lip I6 extends rearwardly from the upper part of the'body portion i 3 of the sealing strip into similar engagement with the relatively elevated inner cap portion IB of the sill.
'I'he body portion I 3 is preferably spaced slightly from the vertically extending portion I9 of the sill, providing an air pocket 20 which is sealed oft by the lips I5 and I6. With this improved sealing strip construction, incorporating a second rearwardly and vertically oilset seal, leakage will be prevented even though water or other foreign matter may collect on the sill outside the sealing strip and even though minor warping or indentations be present in the sill.
In the modiiication shown in Fig. 4 the body portion 2l of the sealing strip is constructed as a resiliently yieldable tube, Without the addition of any separate lip; while in the modication shown in Fig. 5 thebody portion 22 terminates at its lower edge in a relatively soft sponge rubber section 23.
I claim: Y
1. In a. window having a vertically slidable sash. and a sill provided with an inner relatively elevated cap portion located inwardly of the inner plane of the sash, the provision of a rubber sealing strip attached tothe bottom rail of the sash, said sealing strip comprising a vertically compressible body portion beneath the bottom rail for supporting the sash on the sill in the lowermost position oi" the sash, an outwardly extending lip adjacent the lower end of the body portion for engagement with the exposed outer portion of the sill of the window when the sash is in its lowermost position, and an inwardly extending lip adjacent the upper end of the -body portion for engagement with the upper surface of the inner relatively elevated cap portion of the sill when the sash is in its lowermost position.
2. In a window having a vertically slidable sash, and a sill provided with an inner relatively elevated cap portion, the provision of a rubber sealing strip attached to the bottom of the sash, said sealing strip comprising a body portion beneath the bottom rail. an outwardly extending lip adjacent the lower end of the body portion for engagement with the exposed outer portion of the sill of the window when the sash is in its lowermost position, and an inwardly extending lip adjacent the upper end of the body portion for engagement with the upper surface of the inner relatively elevated cap portion of .the sill when the sash is in its lowermost position.
3. In a window having a, vertically slidable sash, and a sill provided with an inner relatively elevated cap portion. the provision of a rubber sealing strip attached to the bottom of the sash, said sealing strip comprising a body portion beneath the bottom rail, an outwardly extending lip adjacent the lower end of the body portion for engagement with the exposed outer portion of the sill of the window when the sash is in its lowermost position, and an inwardly extending lip adjacent the upper end of the body portion for engagement with the upper surface of the inner relatively elevated cap portion of the sill when the sash is in its lowermost position, said body portion of the rubber sealing strip being spaced from the cap portion of the sill when the sash is in its lowermost position, whereby to provide a pocket therebetween, which pocket is closed oit' by said outwardly extending and inwardly extending lips.
4. In a window having a vertically slidable sash, and a sill provided with an inner relatively elevated cap portion, the provision of a sealing strip attached to the bottom rail of the sash, said sealing strip comprising a portion below the bottom rail for engagement with the exposed outer portion of the sill of the window when the sash is in its lowermost position, and an inwardly extending lip adjacent the upper end of the body portion for engagement with the inner relatively elevated cap portion of the sill when the sash is in its lowermost position.
