WEATHER STRIP Fil ed March 24, 1928 VENTOR Patented Oct. 22, 1929 UNITED STATES PATENT OFFICE HARRY E. BRICKER, INGOMAR, PENNElYLVANIA, ASSIGNOR TO NATIONAL METAL PRODUCTS COMPANY, OF PITTSBURGH, FENNSYLVANIA WEATHER STRIP Application filed March 2a,

This invention relates to the art of weather strips and refers to an improved construction particularly adapted to casement or swinging windows. It has in view to provide a strip having a double tongue engagement with the sash at each side of the main base portion of the strip, with an intervening water collecting trough or gutter, and protected leakage therefrom.

The invention also provides a supplemental protecting water drip device for mounting on the sash in position to effectively prevent the entrance of water to the outer tongue and groove joint between the sash and said strip, and other features of improvement, as hereinafter described.

In the drawings showing one preferred embodiment of the invention:

Fig. 1 is a vertical sectional view showing the sash in operative position and engagement with the weather strip;

Fig. 2 is a similar view, showing the sash partly closed toward the strip;

Fig. 3 is a perspective detail view of the protecting water drip device, partly broken away;

Fig. 4 is a similar view of the improved strip as made for attachment to the sill;

Fig. 5 is a similar view of the co-operating groove member for the sash.

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.

The main sealing element against weather, wind, rain, etc., is the box-shaped strip C mounted on the sill and adapted to make tongue and groove engagement with the sash.

Strip C is formed of suitable thin sheet metal, as zinc, bronze, etc., shaped by dies from a blank to form it into the cross sectional shape shown, of any suitable length. As shown, the middle bottom portion 2 is flat for attachment to the sill, by screws 3, through countersunk holes therein.

The front or outer portion of the strip is formed by bending the blank upwardly at right angles providing the outer wall i having the inwardly turned terminal sealing tongue or flange 5.

1928. Serial N0. 264,336.

The back or inner portion of the strip is formed by bending the other side of the blank upwardly at right angles to base 2 providing the inner wall 6 having the inwardly turned terminal sealing tongue or flange 7. By such construction, I provide two sealing flanges at varying heights, both extending in the same direction, towards the sash.

Tongue 5 enters a eo-acting groove 8 across the outer face of the sash for sealing engagement in the usual manner common with metal weather strips. Groove 8 may be a bare groove in the wood, or may be provided with a ti-shaped sheet metal lining, as preferred.

For the purpose of effecting a similar sealing engagement with the lower tongue 7, the sash is undercut or rebated and provided with a sheet metal groove member 9 formed by doubling the metal over with an intervening receiving groove space beyond the main securing flange or base 10. The latter is held to the rebated under side of the sash by screws or nails 11, with the doubled groove member 9 seated against the rebated shoulder 12 of the sash, as shown.

As .thus constructed and mounted, the tongues 5 and 7 make sealing engagement with the grooves, effectively closing all spaces between the sill and sash against the weather. By the form adopted, a trough or gutter 13 is provided between the sides 1 and 6 above bottom 2 in which any water passing inwardly over the outer flange, as when the window is onen, or at any other time, will be collected.

For the purpose of effecting outward drainage from the channel 13, I provide one r more leak or weep holes 14 through the lower portion of the outer wall 4;. Such holes are provided by partly punching out the metal. leaving an outwardly bent tongue 15 in the form of a partly severed blank. The tongue 15 effectively prevents the action of wind currents tending to blow water inwardly from the trough, while allowing for and assisting free release of water outwardly. I .ln addition to the sealing action of the tongue and groove engagement between the strip and sash, Iprovide a supplemental protil) tection in the form of an extending coping D, also preferably made of sheet metal.

Such coping is bent from a blank to form an attaching flange 16 having screw or nailing openings 17 for securing attachment to the outer face of the sash A above the groove 8.

Extending outwardly and downwardly from the flange16 is the sloping wall 18 bent inwardly, as at 19, forming the inwardly extending bottom wall 20, rounded reversely, as at 21, and extending outwardly by the short lower flange 22 terminating in the downwardly turned lip 23.

As thus formed, the coping D provides a fender or protector adapted to shed water outwardly and 'awa from the upper outer tongue and groove ]oint, onto the outer sill.

Any waterwhich may run inwardly along the lower surface of wall 20 and into the groove above flange 22 will flow downwardly oil from the lip 23, thus completely avoiding any tendency of water to reach the tongue and groove joint, thus providing ample protection therefor.

The construction as a whole provides for complete sealing and protection by the weather strip, supplemented by the coping, as made and applied. It is comparatively simple, cheap, and effective, and continuously durable.

The 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 of the following claims.

hat- I claim is:

1. In combination with a Window frame having a horizontal surface sill and a casement window adapted to swing over the sill having an'underneath rebated clearance opening, a J-shaped grooved sealing strip of sheet metal having an attaching flange seated upwardly in the rebated clearance opening, and a horizontal groove in the face of the sash above the sealing strip; a sheet metal weather strip sill member having a middle bottom portion secured to the sill, an inner upwardly extending vertical wall having a reversely turned flange for engagement with the groove of the J-shaped sealing strip, and an opposite upwardly extending vertical wall above the sealing strip; a sheet metal weather strip sill member having a middle bottom portion secured to the sill, an inner upwardly extending vertical wall having a reversely turned flange for engagement with the groove of the J-shaped sealing strip, and an opposite upwardly extending vertical wall at right angles to the base having at its top an inwardly turned horizontal flange parallel with the inner wall flange but at a higher level for engagement in the horizontal groove of the sash, the vertical wall being provided with partly punched out openings providing for escape of moisture.

In testimony whereof I hereunto aflix my signature.

HARRY E. BRICKER.

at right angles to the base having at its top an inwardly turned horizontal flange parallel with the inner wall flange but at a higher level for engagement in the horizontal groove of the sash.

2. In combination with a window frame having a horizontal surface sill and a case inent window adapted to swing over the sill having an underneath rebated clearance opening, a J-shaped grooved sealing strip of sheet metal having an attaching flange seated upwardly in the rebate'd clearaneeopening, and a horizontal groove in the face of the sash
