WEATHER-STRIP.

Specioation of Letters Patent.

Patented Oct. 7, 1919.

Application illed August 10, 1917. Serial No. 185.598.

To all whom. 'it may concern Be it known that I, JoiiN A. HENDERSON, n born citizen of the United States, residin at Portland, in the county of Multnomah an State of Oregon, have invented certain new und useful Improvements in Weather- Strips, of which the following is a specification.

This invention relates to new and useful improvements in weather strips for doors and windows and the principal object of the invention is to provide a device of this nature, more particular] adapted for use on easement windows, which-will ermit the sash to be hung to swing inwar ly, instead of outwardly.

Another object of the invention is to provide a device of this character which will work by gravity and without the use of springs or the like.

A further object of the invention is to provide a device which will completely close the space between the bottom of the sash and the frame so as to prevent the entrance of wind, rain or snow while permitting free movement of the sash when being opened or closed.

In carrying out my invention I utilize a metal strip pivoted in a recess formed in the bottom edge of the sash and carrying a piece of felt at one edge and a counterbalancing weight at its other ed e for normally holding the strip within ie recess. I provide a pivoted member adapted to engage a part of the window frame when the sash is closed so as to be forced inwardly against the strip to swing the same downwardly into position toucause the felt to be pressed against the s1 Another object of the invention is to rovide a device of this character, whic is simple and durable in construction, reliable and ecient in operation and one which can be manufactured and placed upon the market at a minimum cost.

The invention also consists in certain other features of construction and in the combination and arran ement of the several arts, to be hereina ter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings, wherein like characters denote like or corresponding arts throughout the several views, and in W ich Figure 1 is an edge view showing the lower part of the sash with my invention applied thereto.

Fig. 2 shows one corner of the sash provided with my invention.

Fig. 3 is a horizontal transverse section showing part of the sash and the window frame with the parts in closed position.

Fig. 4 is a vertical transverse section with the parts in the position shown in Fig. 3.

Fig. 5 is a view of the weather strip with parts broken away, and

Fi G is a cross section through the weat er strifp.

In these gures 1 represents part of the window frame, 2 the casing, 3 the sill and 4 the stool. 5 represents the sash which may be pivoted or hinged and adapted to swing inwardly. 6 represents a recess formed in each side of the window frame to receive the sash, as is well known.

In carrying out my invention I provide a recess 7 in the bottom edge of the sash, said recess having a curved innerwall while adjacent the outer edge of the sash the recess is irovided with a rectangular portion 8 of re uoed depth. 9 represents the weather strip pivoted in the said recess by means of the rod 10. This weather strip is formed of sheet metal folded upon itself and at the folded part being looped around a rod 11 and then having the two portions of the sheet brought together and extended parallel to about midway of the stri where one of the portions is looped aroun the pivotal rod 10 and then the two portions are brought together again and extend parallel uto a point adjacent the free ends, where said ends are curved downwardly and spaced apart so as to grip the piece of felt 12 between them. The weather strip is of sufficient length to extend substantially across the lower edge of the sash but being slightly shorter than the sash so as to lit between the pair of plates 13 located at the bottom of each side edge of the sash, each of said plates having an opening therein to receive the end of the rod 10 to pivot the same in osition. The weather strip is so proportione that it will lie entirely within the recess 7 and its extended portion 8 and the rod 11 will act as a weight to normally hold the weather .strip within the recess as clearly shown 4'in Fig. 1.

The plate 13 covers the rectangular recess 14 formed in the lower side edge of the sash and this` recess communicates with the ends of the recess 7, it being understood that there is a recess 14 on each side edge of the sash. The said iecess extends through the outer side of the sash and the plete l5, having a. slot 16 in its lower part, is secured to the outer side of the window and rovers said recess. A lever 17 is located in the said recess and has its upper end pivoted to the sash in the upper part of Said recess, as at 18, and said lever is provided with an enlarged head 19 having its lower end rounded and havingr an inclined part connecting said rounded end with the mein part of the lever. Thus u rojecting point 20 is formed at the point w 1ere thc inclined part joins with the rounded end and this point engages the weather' strip, thereby reducing the friction of the lever on the weather strip. 'lhe lever is so located that the rounded end ol the head thereof will project through the slot 16 in the plate 15 and will contact with the bottom of the recess 6 in the window `iframe when the sash is closed. To prevent wear of the frame I locate a plate 21 on the bottom of this recess with which the lever will engage. On the outer edge of the stool 1 I rovide an inclined part 22 to receive the elt 16 carried by the weather strip.

When the window is opened the weight of the rod 11 will overcome the weight of the level' 17 so that the weather strip and lever will assume the positions` shown in Figs. 1 and 2, said lever having a portion projectingr through the slot 16 and the weather strip beingr parallel with the bottom edge of the sash and being within the recess. When the sash is closed the rounded end of the enlarged head of the level' 17 will come in Contact with the plate 21 so that the said lever will be forced inwardly and downwardly thus pressing aga-inst the weather strip so as to force the outer edge downwardly while the end carrying the rod 11 will swing upwardly within the recess. Thus the felt 12 is pressed ageinst the inclined part 22 of the stool thus closing the space between said stool and the lower edge of the sash. I locate a Strip 23 of rubber or the like in the upper mrt of the recess 7 with which the inner edge of the weather strip will engage when the same is forced upwardly by the lever. This will prevent the wind from passing through the recess 7 in the .sash and thus entering the room.

It will be understood that the lever 17 may be made in a different way from that shown. For instance it may be provided with e screw on its lower end which will come in contact with the plate 21 so that the pressure of the seid lever on the weather strilg may be regulated.

bile I have shown the invention applied to a window it will of course be understood that it may be applied to doors as well, and due to the fact that a considerable space may be left between the bottoni edge of the door and the sill, the door will readily pass over rugs und the like. Y

It is thought from the foregoing thai the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I muy make slight changes in the construction and in the combination and arrangement of the several parts, provided that such changes `fall within the scope of the appended claim.

I claim The combination with a sash having` a recess in its lower edge, of a member pivoted in said recess and normally tilting out of operative position, a lever pivoted in said recess above the pivot of said member and adjacent the inner side of said recess, the lower end of said lever projecting through and beyond the outer face of said sash, said lower end of the lever being semi-circular in configuration to exert a comming action between the outer end of said member and a window frame to tilt. and retain the outer end of said member in close engagement with a. sill when the sash is closed.

In testimon whereof I affix my signature in presence o two witnesses.
