WEATHER STRIP.

Application filed April 4,

This invention relates to the art of metal weather strips and refers to an improved construction particularly adapted to cases men-t or swinging windows. It has in view to provide a compound strip construction having a tongue and groove engagement when closed, by means of a sheet metal trough-shaped sill member and a co-acting sheet metal sash member adapted toopen and close therewith for sealing and protecting engagement.

ln the drawings showing one preferred embodiment of the invention:

Fig. 1 is a vertical sectional view showing the sash in operative positionand with the two members of the compound strip in engagement;

Fig. 2 is a similar View, showing the sash partly closed towards the strip;

Fig; 3 is a perspective detail viewv of the sash member; y

Fig. 4- is a similar view ofthe sill inemher;

Fig. 5 member.

Referring to the drawings the window sash A is of the usual casement or swinging type, hinged at one side and adapted to swing towards and from and over the usual sill B. i

The main sealing elements against weath- I or, wind, rain, etc., are the box-shaped strip C mountedonsthe sill and adapted to make tongue and groove engagement with the cop ing member D, and also withthe sash.

Strip G is formed of suitable thin sheet metal, preferably non-corrosive, as zinc, bronze, etc, shaped by dies from a blank to form it into'the cross sectional-shape shown, Y of any suitable length. i V

' The middle portion 2 is adapted to beattached to the sill by screws 3, through holes 4rtherein as shown. The. front or outer portion 5 of the strip is formed by bending the blank upwardly and outwardly at an angle of more or less to the plane of the bottom contacting surface, and then inwardly, parallel to the bottom plane, pros vi ding the sealing tongue or flange 6.

The back or inner portion of the sill str1p is formed by bending the other side of the blank upwardly at right angles to the plane of the base providing the inner wall or is a partial face view of the sill flange 7.

The sash A as shown is rebated asat 8 1928. Serial 110,267,277.

whereby to provide clearance and an abutting shoulder for engaging the flange 7 when closed, as in Fig. 1. Such. engagement limi ts the movement of the sash while also forming a contacting seal.

h For the purpose of effecting a close sealing engagement with the tongue 6, the sash member D having. the lower tongue engaging 'fl ange or "groove, the outwardly protecting coping, and the upper attaching flange is provided. Member D is sinnlarly made of sheet metal. bent from a blank to form an attaching. flange 9 having screw or nailing openings 10 for securing attachmentto the outer face of the sash A sufficiently above the level of the tongue 6' for engagement therewith. I

The upper edge of flange 9 is bent inwardly slightly, as shown, for good contact against the face of the sash when secured thereto by the screws or nails.

Extending. outwardly and downwardly from the flange 9 is the coping wall 11 bent around inwardly as at 12, forming the rounded edge and the inwardly extending bottom wall 13. i

Said wall is rounded reversely on itself,

flange'16, preferably turned down sli htly, as shown. i

' as at 14-, and extends outwardly with the intervening groove 15 terminating in the Asthusformed, the coping D provides a fender coping or protector adapted to shed water outwardly and away from the still member when engaged therewith, and to closely Contact with and engage the tongue 6 by the, b i'l the lower flange 16.

The coping D as thus made and secured by its upper edge is sufficiently resilient to' adapt itself to the tongue in closing and opening, while the rounded edge 14- bears back againstthe face of the sash, ensuring resistance in closing against the tongue 6.

\Vhen thus closed the parts are in comparatively tight engagement, completely sealing the joint."

The sill member C provides a trough or gutter between its front sloping wall 5 and rear flange 7 for-collection of water or snow that may pass inwardly over its front flange 6, asv when thewindow is wholly or partly open.

portion of wall 5 are provided leak. or weep double-sided groove 15, or merely At suitable intervals along the lower front holes 17 formed by partly severing the metal and forcing it downwardly and outwardly, as at 18. By such arrangement the tongue 18 effectively prevents the action of wind currents tending to blow water inwardly from the interior trough cavity between the walls 5 and 7, while allowing for and assisting free release of water outwardly.

The base portion 2, as shown, is arched upwardly between its lateral bearing edge portions, adapting the strip C to be laid upon and secured to the flat surface or the sill B by the screws By upwardly arching the bottom as shown,a limited degree of adjustment oi the tree teri'ninal edge portions of the strip is provided, by tightening or loosening the screws. In this manner the tongue 6 may be thrown upwardly or downwardly, adapt. it to accurate fitting within the groove 15, and the wall 7 may also be proportionately adjusted. Said wall provides a strong, sub" stantial abutting stop for the windoi'v so as to limit its movement definitely and properly for in'terfitting engagement with the sill strip.

Theconstruction as a whole provides for complete sealing and protection by the weather strip, supplemented by the coping as made and applied. The tongue and groove members have suflicient resiliency to adjust themselves to each other, while the free edges of each strip member are completely concealed and protected within a generally rounded contour when in engagement.

The device is comparatively simple, cheap, and elfective, and continuously durable.

vThe proportions, dimensions, or specific detail features may be changed or modified by the skilled mechanic, but all such changes are to be understood as within the scope oi? the following claims.

What I claim is:

1. In a casement window weather strip, the combination with a sill member having an attaching base provided with an inner sash engaging wall and an outer upwardly sloping wall having an inwardly turned flange, of a sash member having an upper securing flange and an outwardly disposed downwardly sloping wall reversed inwardly and doubled upon itself providing an unattached resilient under-engaging flange'for engagement with the flange of the sill member.

, 2. In a casement window weather strip,

the combination with a sill member having an attaching base provided with an inner sash engaging wall and an outer upwardly sloping wall having an inwawlly turned flange, of a sash member having an upper securing flange and an outwardly disposed downwardly sloping wall reversed inwardly and doubled upon itself providing an unattached resilient bottom embod ing an outwardly open groove for engagen at with the flange of the sill "member.

3. In a aiseinent window weather strip, the combination with a sill member having an. upwardly arched bottom forming an attaching base provided with an inner sash engaging wall and an outer wall having an inwardly turned flange, of a sash member having a securing flange and an outwardly disposed wall reversed inwardly and doubled upon itself providing an inter-engaging flange for engagement with the flange oi the sill member.

l. In a casement window weather strip, the combination with a sill member having aii attaching base provided with an inner sash engaging wall and an outer wall provided at its bottom with partly punched out openings providing protected leak openings and terminating in an inwardly turned flange, of a sash member having a securing flange and an outwardly disposed wall reversed inwardly and doubled upon itself providing an under-engaging flange for engagement with the flange of the sill member.

5. In sheet metal weather strips, the combination with an open top sill member hav ing an inner vertical wall, an upwardly curved base and an outer upwardly extending inwardly flanged wall, of a sash member having an attaching flange, an outwardly projecting coping wall and a lower open sided double wall groove portion for en gagement with the inwardly flanged wall of the sill member. 7

In testimony whereof I hereunto allix my signature. HARRY E. BRECKER.
