Specification of Letters Patent.

Patented May 28, 1907.

Application filed September 10, 1906. Serial No. 833,229.

Sill, of which thefollowing is a specification.

This invention relates to Window frames and sashes generally, but is more especially intended for use in connection. with that class of windows'used in houses, and has particular relation to the construction of the sill and lower rail of the lower sash, whereby air, dust, rain and snow is excluded from the room, and the rattling of the sash and the sticking or binding of the same is prevented; and it consists in certain peculiarities of the construction, novel arrangement, and o eration of thevarious arts thereof, as W1ll be hereinafter more fu ly set forth and specifically claimed.

In order to enable others skilled in the art to which my invention pertains,- to make and use the same, I will now proceed to describe it, referring to the accompanying drawing, in which- Figure 1 is a fragmental erspective view of a window-frame and the ower sash thereof, showing a window sill embodying my invention. Fig. 2 is a cross-sectional view througha ortion of the lower sash and sill, construct-ea according to the invention. Fig. 3 is a perspective view of a portion of the sill;-andFig. 4 isa sectional perspective view of a portion of the lower sash rail.

Like numerals of reference, refer to corre- 7 spending parts throughout the different views of the drawing. 1 4 The reference numeral 5 designates a portion of a window-frame of the ordinary or any preferred construction, the sill 6 of which'is provided at a point near the inner surface of the lower rail of the lower sash with a horizontally extended window stool 7, against which the inner surface of the sash rail 8 may rest. Located longitudinally on the upper surface of'the sill 6 and outwardly from t e stool 7 thereof'is a sealing stri of metal, preferably zinc, which has a flat ase portion 9' which is secured to the sill 6 by rivets or spikes 10, or otherwise. At the outer edge of the base portion 9 of the sealing strip is provided or produced an upwardly and longitudinally extending rib 11, which has an outwardly and downturned flange 1.2 which extends the entire length of the dra the channe 13 so that when the ower sash what I claim as new and desire the portion 11, and as clearly shown in Figs. 1 and 2 of the drawing, is slightly inclined outwardly so as to be separated from the portion 9, and said "flange is narrower than the portion 9 and has its lower ed e free, as. shown. The lower surface of the ower rail .8 of the lower sash is formed'with alongitue dinally extending channel 13, which is preferably rectangular in shape and of sufficient width and depth to freely receive thesealing rib 11 and its downturned flange. Longitudinally secured on the lower surface of the rail 8 and between the channel 13 therein, and the outer surface of the rail, is a flat or base portion 14, of a metallic strip ,,which has at its inner edge a longitudinal flange 15 which, as is clearly shown in Figs. 2 and 4 of extends 'obliquelyu ward into rail 8 is lowered to the positions shown in Figs. 1 and 2 the flange 12 on the sealing rib 11 will impinge against flan e 15 of the plate or stri 14, thus forming a (floss joint to prevent t e passage of air, dust, rain and snow between the rail 8 and-the sill 6 into the room, for it will be understood that as the flange 12 is sli htlyseparated at its lower portion from the rib 11, it, aswell as the flange 15, may have a certain degree of re- .silienc which is exerted toward each other,

thus orcing the two flanges closely and firml together, yet they will eld sufiicoming bound'when swollen bythe action of the weather between the stool 7 and the rib 11of the sealing strip. The plate '14 will also revent that ortion of the rail 8 to 'cient y to prevent therail 8 stic 'ng or bewhic it is secured becoming decayed by absor tion of water, as is apparent. v p l -laving thus fully described my invention, to secure by Letters-Patent, is-

In a weather proof window sill, the combination with the sill, of astool horizontally located on the upper surface thereof, a metallic sealing strip having'a base portion se-' cured to the sill outwardly from the' stool and provided at its outer edge with a longitudinally and upwardly extending rib provided at its upper edge with an obliquely downwardly and outwardly extending flange, the said flange being spaced from the rib at its lower ortion and extended to'near the lower portion of. the rib, a vertically niovably lower sash rail having in Its lower surface a longitudinally extending channel III open at its bottom, and a metallic strip or plate secured to the lower surface of said rail outwardly from the channel therein and having a lOIlgltl ldiIlfll flange on its inner portion obliquely and upwardly extended from the lower portion of the outer Wall of said Channelto overlap and co-act with the flange of the sealing rib whereby a yielding and close joint is produced, substantially as described.
