INIPROYED'WEATHER-STRIP FOR WINDOWS.

The Schedule referred to in these Letters Patent andsmaking part of the same.

To all lwhom, it may concern Be it known 'that I, ANDREW JACKSON Davon, of Hackensack, inthe county of Bergen, and State of New J ersey,have invented a new and improved Weather- Strip for Window-Sash es and I do hereby declare that the following is a'full, clear, and exact description thereof, which will enable others. skilled in the art to make and use Athe same, reference being had to the accompanying drawings, forming part of this specication.

,Y Figures l and 2 are vertical transverseA sections of window-frames, provided with my improved weatherstrip attachment.

Figure 3 is a detail plan or top view of the lower strip. A

Figure 4, a similar viewof the upper weather-strip.

Similar letters of reference indicate' coi-respending parts.

This invention relates to a newweather-strip for windOw-sashes, by means of which air and water are eiectually prevented from being blown through the crevices between the sashes and underthe lower sash.

The invention consists, iirstin the application of a sliding sheet-metal plate, On the upper edge of thelower sash, which plate can be so placed as to cover the crevice between the two sashes; second, in the application of a swinging plate to the window-sill, and of swinging lugs under it, so that when the lower sill is letvdown it will strike the lugs, and thereby elevate the swinging plate, which will then remain in a sloping position, to'

form an inclined weather-strip for the lower part of the window.

A, in the drawing, represents a window-frame Of ordinary Or suitable construction. Y

B is the lower, and C, the upper sash of the same.

On the upper edge ofthe lower sash," B, is arranged a sheet-metal, or other plate, D, which is as long as the sash, and which is fastened to the sash by means of screws Or Otherwise.

The,- said screws, or their equivalents, are tted through transverse slots a a, provided in the plate D,

so as to allow lateral motion tO said plate.

When the sashes are both closed, as in lig. 1, the

plate D may be pushed out, so as tO partly cover the lower bar b of the -upper sash, thereby covering the crevice between the sashes, as is clearly shown in iig. l.

In this position the plate D may also' serve as a sash-fastener, by fitting into notches c, provided in the side bars of the upper sash, as shown.

The upper sash is thereby locked to the lower one, and neither can be moved, unless the plate D is drawn in, as in iig. 2. V

To the sills E of the window-frame are hinged Or pivoted, under the lower sash, two, or more or less, narrow, bent plates, il d.

To the same sill is hinged, outside of the lower sash, a plate, F, which swings On its Outer edge, and which rests on theouter ends ofthe plates d, as in g. 2.

When the lower sash `is raised, the plate F, with its weight, holds down the outer ends of the plates d, so

that their inner ends stand up, as in iig. 2; but when the lower sash is brought down, it will depress the inner ends of the plates d, thereby raising their outer ends, whereby the plate F is caused to swing up, as in fig l'.

the outer face of the lower sash with almost equal effect.

Having thus described my invention,

I claim as new, andv desire to secure by Letters The plate. F iits then under a ledge, 6, formed on thev Outer face Of the lower sash, and forms a secure weatherstrip, as shown in iig. l, or it may simply lit against
