WEATHER-STRIP.

Specification of Letters Patent.

Patented Sept. 19, '1905.

Application filed March 20, 1905- Serial No.250,893.

such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved weather-strip especially adapted for application to casement-windows and to. doors; and to this end it consists of the novel devices and combinations of devices hereinafter described, and defined in the claims.

The weather-strip herein disclosed is of the type which is movable into and out of o erative position under swinging movements of the window or door. Hitherto weatherstrips have been provided which are capable of such movements; but in all cases, so far as I am aware, their movement has been accomplished by supporting devices located at both ends of the weatherstrip and subject to cams or abutments located at both sides of the window or door frame.

My invention provides a novel form of sup- 1 port and actuating device for the movable weather-strip and which actuating device is applied to only one end thereof, is subject to one or more abutments located at one side only of the window or door frame.

This improved device. is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the'several views.

Figure 1 is a front elevation, with some parts broken away, illustrating my invention as applied to the casement-window. Fig. 2 is a similar View to Fig. 1, but showing the hinged sash swung partly open and awayfrom the observer; and Fig. 3 is a section taken on the line 00 x of Fig. 1.

The numeral 1 indicates the fixed windowframe, the sill of which has the usual stop 2.

The numeral 3 indicates the swinging sash, which is connected to the frame at one side by hinges 4. As shown, this sash is arranged to swing outward; but it mightv of course be made to swing inward and the stop 2 might be dispensed with.

In the lower edge of the sash 3 is a groove 5, that receives loosely a bar 6, preferably of metal. A flexible weather-stri 7 underlies the lower edge of the bar 6 an at one edge is attached to the lower edge of the sash 3, as shown, by brads 8. By a downward movement of the bar 6 the flexible strip 7 is adapted to be tightly pressed against the sill 1 to thereby form a tight joint between the sash and the sill. The bar 6 and the flexible strip 7 make up the weather-strip proper; but it will be understood that the flexible stri might be directly applied to the bar 6, and furthermore, that the said flexible-strip in some cases might be dis ensed with and the bar itself relied upon to orm a tight joint with the sill.

At that end of. the bar or weather-strip 6 which is adjacent to the hinged edge of the sash it is provided with a cam-surface 9, Which when the sash is closed engages with an abutment 10, shown as afforded by a screw or :stud, which is shown as screwed into the adjacent side of the' window-frame. Above the cam-surface 9 the sash is cut away at 11 to afiord a seat for a bell-crank 12, which is pivotally attached to the sash at 13 and is subject to a spring 14, that yieldingly acts on the downturned end of said bellcrank to force the same upward. The downturned end of said bell-crank is pivotally attached at 15 to the bar or strip 6 a short dis? tance inward from the cam-surface 9, and the upturned end of said bell-crank is adapted to engage with ,an abutment 16, shown as screwed into the adjacent side of the window-frame abovethe abutment 10. Both of the abutments 10 and 16 are adjustable, and, as shown, they work freely through perforations 17 of a metallic plate 18, which is countersunk into the adjacent edge of the sash and is rigidly but detachably secured thereto by screws 19 or other suitable devices.

When the parts are properly adjusted, the

arm of said bell-crank and then lifting they said strip bodily upward into an inoperative position. When the sash is swung from its open into its closed position, the cam-surface 9 is brought into contact with the abutment 10 and the upper arm of the bell-crank 13 is brought into engagement with the abutment 16. The engagement of the cam-surface 9 with the abutment 1O crowds the adjacent end of the bar or strip 6 downward onto the flexible strip 7, and said abutment 10 then affords a base of reaction or fulcrum, over which the bell-crank 12 acts under its downward movement to force the free end of said strip 6 downward onto the flexible strip 7. It will thus be seen that the weather-strip is forced into its operative position by a device applied to one end only thereof and that this device is actuated positively under the closing movement of the sash. The improved device when applied to a door will act in the same manner or substantially in the same manner as when applied to a swinging sash.

The device while extremely simple and of small cost has in practice been found efficient for the purposes had in view. From what has been said it will be understood that the said device is capable of a large range of modification within the scope of my invention as herein set forth and claimed.

What I claim, and desire to secure by Letters Patent of the United States, is as fol lows:

1. The combination with a window-sash or door, and its frame, of a weather-strip applied to the lower edge of said sash or door, a

lever connecting one end of said strip to one side of said sash or door, said strip having a cam-surface at its supported end, and a pair of abutments on said frame, the one engageable with said lever, and the other with said cam-surface, and the two operative under the closing movement of said sash or door, to positively force said strip into an operative position, substantially as described.

2. The combination with a swinging sash or door, having at its lower edge a groove 5, of a bar or strip 6 mounted in said groove, and provided at one end with a cam-surface 9, a bell-crank lever 12 pivotally mounted within said groove and pivotally attached to said bar 6, inward of said cam 9, a spring tending to force said bar into a retracted position, and fixed abutments 10 and 16 engageable with said cam 9 and the free arm of said bell-crank respectively, under closing movements of said sash or door, to positively force said bar or strip into an operative position, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
