HENRY HIGGIN, OF NEWPORT. KENTUCKY, ASSIGNOR TO THE HIGGIN MANUFACTUR- ING COMPANY, OE NEWPORT, KENTUCKY, A CORPORATION OF WEST VIRGINIA.

WEATHER-STRIP.

Application filed April 7, 1913.

To all whom it may concern Be it known that I, HENRY HIGGIN, a citizen of the United States, and a resident of the city of Newport, in the county of Camp bell and State of Kentucky, have invented certain new and useful Improvements in lVeather-Strips, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

The object of my invention is to provide a weather strip construction to be applied to easement windows opening inwardly, by which an effective closure may be obtained to prevent the entrance of air and the elements when the window is closed.

Inasmuch as in casement windows which open on the inside, the sill must be free and clear to allow for the opening of the casement, it has been found exceedingly difficult to provide a construction of weather strip which shall be effective, under all conditions, to prevent driving rain from seeping around the openings and entering around and underneath the window.

It is the object of my invention, therefore, by the novel construction and arrangement of parts which will be hereinafter particularly pointed out and claimed, to effect this object.

My invention is particularly directed to the efiective closing of the sill of the casement window frame, although provision is also made for effectively closing the sides of the frame.

In the drawings, Figure 1 is a front elevation of the lower portion of a casement window, viewed from the outside. Fig. 2 is a transverse section, in perspective, of the lower portion of the frame, taken on the lines 2, 2, of Fig. 1. Fig. 3 is a cross section showing a slight modification. Fig. 4 is an enlarged cross sectional perspective view of the lower rail of the sash. Fig. 5 is a perspective view of a portion of the sill plate.

I have illustrated the lower portion of the framework of a casement window frame showing the sides 1. 1, and the sill 2. On one of these sides the easement window 3 is hinged by hine'es 4, to open inwardly. The bottom rail of the sash is indicated by the numeral 5, with light of glass 6. The sill 2 is formed with a shoulder 7, against which the front face of the bottom rail of Specification of Letters Patent.

the sash abuts. The outer portion of the sill is formed with a downwardly sloping surface 8. The front face of the bottom rail of the sash is provided with a horizontal groove 9 running the entire length of the sash. This groove has parallel side walls, but is widened out slightly at the corners in the back of the groove, as shown at 10, 10. In this groove is seated an insert, preferably formed of sheet metal. This insert has a broad base 11 to fit in the hack of the groove, is rounded at the corners, and with the side walls 12, 13, of the insert bent toward the middle plane of the groove and with the ends rounded and turned outwardly at 14, 15.

Mounted on and covering the outer surface of the sill is the metal plate 16 preferably secured by screws 17. This plate has an inwardly projecting flange 18, which is preferably formed by doubling the outer edge back on itself as shown in the drawings, so as to give sufficient thickness to contact with the projecting curved portions of the walls of the insert, when the window is closed and thus to spread the walls and insure a close. spring contact with the flange above and below and throughout its length. But even with this. under a driving rain, water might run down the sash and be driven in around the flange to seep under the sash. In order to insure air and water tightness. however. I provide the sheet metal plate 19 as a fender secured to the front face of the sash bv screws or otherwise. immediatelv above the groove for its entire length. This fender is curved len thwi e for its upper and lower edge at 20. 21. The upner edge is thus brought into close contact with the surface of the sash to pre ent the entrance of moisture behind it. while the lower portion 21 is curved to come into close contact with the flange 18 when the sash is closed and the edqe of the fen er bears upon the curved outer portion of the up er wall of the insert. In tead of terminating at the outer portion of the insert wall. the lower portion of the fender plate can be carried in ardly well into the groove as shown in Fi 3. With this double protection of the insert and flanged late and the fender plate. anv ent ance of dust. air or moisture is most efiectiveiv prevented. The double cur ature of the fender plate and the fact that it is secured along the middle portion gives a resilient pressure to the upper and lower edges which is most effective in causing a uniform closure both along the sash above and the flanged plate below.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a weather strip construction, the combination with the bottom rail of a sash provided with a longitudinal groove in its outer face, with a'resilient sheet metal insert seated therein, of a sill plate extending the length of the sash groove provided with an inwardly projecting flange to engage the insert, and a fender plate secured to the sash rail parallel with the sash groove and with the lower portion of the fender adapted to engage the sill plate when the sash is closed.

2. In a weather strip construction, the combination with the bottom rail of a sash provided with a longitudinalgroove in its outer face with resilient sheet metal insert seated therein, of a sill plate extending the length of the sash groove provided with an inwardly projecting flange to engage the in sert, and a fender plate secured to the sash rail parallel with the sash groove, and with the lower portion of the fender curved in- Wardly and adapted to engage with its lower edge the insert, and with the curved portion the sill plate when the sash is closed.

3. In a weather strip construction, the combination with the bottom rail of a sash provided with a longitudinal groove in its outer face with a resilient sheet metal insert seated therein, of a sill plate extending the length of the sash groove provided with an inwardly projecting flange to engage the insert, and a fender plate reversely curved in cross section secured at its middle portion to the sash rail parallel with the sash groove, with its upper edge engaging the surface of the rail and with its lower portion curved inwardly and adapted to engage the sill plate when the sash is closed.
