UNITED STATES WILLIAM R. WOOD, OF GRAFTON, PENNSYLVANIA.

WEATHER-STRIP DEVICE.

Application filed August 19, 1921.

To @ZZ whom t may concern.'

Be it lrnown that I, VILLTAM R. Woon, a citizen of the United States, residing at Grafton, in the` county of Allegheny and State of Pennsylvania, have invented certain i new and useful Improvements in Teather-Strip Devices, of which the following is a specication.

This invention relates to a metal weather strip for windows, anda groove liner to be used in connection therewith.

In applying metal weather strips as heretofore constructed, and in applying groove liners with which the weather strip cooperates, it has been the usual practice to employ nails or brads which are driven through the metal into the wood. Such fastening devices are liable to work loose and the headsthereof are liable to interfere with the proper operation of the sashes.

Furthermore, in wooden sashes to be used in connection with metal weather strips, it is customary to send. the sashes out from the mill some time prior to the time they are hung or fitted into the casing. During this interval, and evenI afterI the sashes are hung, they have `a tendency to warp. This warping of the sashes causes considerable trouble in fitting the sash in the frame `and considerable ditlicultyl is encountered in cutting straight grooves in the sashes to receive the weather strip. Even after the grooves vhave been cut andthe usual U-shaped groove liner has been applied, and after the sash has been hung, the sash will warp, causing the window to stick. Heretofore, to my knowledge, it has not been possible to 'cut the groove in the sashes at the mill and apply the liners, so that the sash can be delivered from the mill all ready to be'hung and without danger of warping. A fprimary object of the present invention isto pro vide a weather strip device, either' a weather strip or a groove liner, having integral securing means thereon arranged and adapted to be` driven into the wood, so that the use of nails or other separate fastening means is obviated.

A.- further objectis to rprovide a groove liner formed in such manner that it may be applied at the mill after the first cutting of the groove, and which will resist the tendency of the sash to warp.

My invention is illustrated in the accompanying drawings, in which:

Fig. l is a horizontal section through a Serial N'o. 493,505.'

portion of a sash and frame, showing a groove liner embodying my invention;

Fig. 2 is a perspective View of the groove liner, detached from the sash;

Fig. 3 is a Vplan View of a strip of sheet metal, illustrating the method of forming the groove liner;

Fig. 4 is an end view of the strip shown in Fig. 3, the dotted' line formation indicating the final cross sectional shape of the strip after bending;

Fig. 5 is a perspective view similar to Fig. 2, but of a slightly modified form;

Fig. 6 is a similar view of another modiication for use in connection'with a doubletongued weather strip;

Fig. 7 is a similar view of a weather strip embodying my invention.

In the drawings, A represents the side of a sash, P) indicates the groove liner, and C indicates the metal weather strip carried on the sides of the window frame D.

T he liner B is formed from a flat strip of metal. Thestrip is first cut to provide teeth or serrated edges 5, and tangs 6 are punched ont at intervals from the center thereof. It then bent so that it has a central U-shaped portion having a bottom 7 and sides 8 adapted to tit into the groove. rl`he tops of the sides 8 are provided with bent or flattened portions 9, the outer serrated edges of which are bent over at l0. The strip is then ready to be cut into proper lengths, if this has not been done prior to the cutting and bending operations.

ln its finished form, the liner has the central U-shaped channel portion with tangs 6 projecting from the bottom 7 thereof. and with the sides 8 having the laterally eXtending portions 9 at the top thereof, from the outer part of which portions 9 are turned the serrated edges 5. y

The sash A is cut with a groove therein, as shown in Fig. l, and on each side of the slot or groove, the wood is out away, as indicated at a.. This is done so that the groove liner, when applied, will be flush with the face orside of the sash and not proiect be-4 yond the side.

After the groove has been cut in the sash, the groove lineris applied in such manner that the U-shaped central portion enters the groove, while the tangs 6 are driven into, the wood at the'bottom of the groove. At the saine time. the teeth 5 enter the wood at the sides of the groove. A specially formed hammering or rolling tool may be used for applying the liner to the sash.

IVhen in position in the sash, the liner is held in place by the teeth and tangs and the usual brads or nails, which are liable to work loose.y can be dispensed with. The liner, with its serrated edges 5 embedded in the wood, offers a considerable resistance against warping, and a sash provided therewith will not generally warp to any appreciable extent. It is, therefore, possible to apply the liner at the mill and the necessity for having a workman to insert the groove liners when the windows are hung in the casing, is eliminated.

In the construction shown in Fig. 5, the edges, instead of being serrated, are corrngated, as indicated at oa. These corrugated edges can be driven into the wood in the same manner as the teeth 5 shown in Fig. 2, and this construction will also serve to hold the sash against warning.

In Fig. G, I have shown a liner adapted to be used in connection with a double weather strip. In this construction, an integral strip 12 is used, and it is provided with spaced apart U-shaped channels 13 connected byfa Hat portion 14. This flat portion may be provided with instrnck tangs 15 which can be forced into the wood to hold this part of the strip in position. r[he outer edges of the strip are turned over in the manner hereinbefore described, and preferably provided with teeth 16 or other suitable means adapted to be driven into the wood. T angs 13a corresponding to the tangs 6, may also be struck from the bottom of the channels 13.

The groove liners hereinbefore described may be arranged for use in connection with any suitable weather strip. I prefer, however, to make the weather strip C as shown in Fig. 7, from a sheet of metal folded to provide a tongue 18, a flat portion 19 at each side thereof, and with bent over edges 20 arranged to be forced into the wood. The bent over portions are preferably serrated to provide teeth 20a, as shown.

It will thus be seen that I have provided a weather strip device which is self-securing, and which, when applied to a sash, will resist the tendency of the sash to Warp. It is contemplated that various changes may be made in the invention within the scope of the ap pended claims. It is also contempla-ted that the improved weather strip could be applied to the sash and the grooves formed in the frames or casings, and that the liners be used in the grooves in the casing.

I claim as my invention:

1. A groove liner for sashes comprising a metal strip having a channel formed therein Twhich is adapted to be received in a groove.

and turned over edges at the side of the channel having integral means thereon adapted to be driven into wood to hold the liner in position, said edges being turned back in the same direction as the channel and overlying the channel.

2. A groove liner comprising a strip having a central channel portion with a bottom` and sides, turned over edges at the upper part of the sides, said edges being turned back over the channel portion of the strip and parallel therewith, and a portion on said edges arranged to be driven into a wooden sash.

3. A groove liner for sashes comprising a strip having a central channel adapted to be received in a groove having a bottom and sides, turned over edges at the top of the sides.v said edges having a portion thereof arranged to be driven into a wooden sash, and integral means at the bottom of the channel portion arranged to be driven into said wooden sash.

4. A groove liner for sashes comprising a strip having a central channel portion adapted to be received in a groove in a wood sash and having a bottom and sides, and edges at the upper part of the sides turned back over the channel p ortion and parallel therewith and having serrations formed thereon arranged to be driven into the wood of the said sash.

5. A groove liner for sashes comprising a strip having a central channel portion adapted to be received in a groove in a sash and having a bottom and sides, tangs adapted to be forced into the sash on the bottom of the channel portion, and turned over edges at the upper parts of the sides having serrations formed therein arranged to be driven into the sash.

6. A groove liner for sashes comprising a strip having a channel portion and in tegral means thereon overlying the channel and parallel with the groove adapted to be driven into the sash for holding the strip in place and for resisting the tendency of the sash to warp.

7. A groove liner for sashes comprising a metal strip having a channel portion adapted to be received in a groove in a sash, laterally extending flanges at the sides of the channels, the outer edge portions of the channels being turned back to overlie the channel and being parallel therewith, such turned back edges being adapted to be driven into a sash, whereby the tendency of the sash to warp is resisted.

In testimony whereof I affix my signature.
