Specification of Letters Patent.

Patented Feb. lit},

Application filed october 16, 1915. Serial 1t 0. 56,185.

To all whom it may concern:

Be it known that I, HARRY H. Sorrnorien, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and usefulImprovements in Weather- Strips; and I do hereby declare that the fol lowing is a full, clear, and exact description of the same, reference being had to the accompanying drawings and to the numerals of reference marked thereon, which form a. part of this specification.

It is an important object of this invention to construct a weather strip comprising a piece of resilient metal folded over to receive a strip of fabric engaged therein and with the outer margin of the metal strip angled outwardly and slotted to afford a plurality of flexible reinforcing means for ihefabric.

It is an object of this invention to'construct a simple and improved type of weather strip particularly adapted for use upon car windows and of flexible nature acting to spring inwardly beyond the normal plane of engagement with the sash when the sash is moved from closed to openposition and to bear closely upon the surface of the same to seal the same when the same is moved into closed position in the casing.

On the drawings:

Figure 1 is a fragmentary central vertical section taken through a window casing illustrating a weather strip embodying the prin ciples of my invention associated therewith.

2 is a section taken on line 2-2 of Fig. 1.' y

Fig. 3 is a bottom plan view similar to Fig. 2,'illustrating the position assumed by the weather stripping means when the sash is moved into an open position.

Fig. 4 is an elevational view of the weather strip shown detached from the eas- Fig. 5 is a detail section taken on line 5-5 of Fig. v

Fig. 6 is a fragmentary exterior elevatiion of a window sash and frame of different construction equipped with a modified form of my invention.

Fig. 7 is a section on line 7-7 of Fig. 6.

Fig. 8 is a sectional detail of the weather strip when detached from the sash.

Fig. 9 is a sectional view partly in elevation through the lower end of a window sash showing my invention mounted to seal against the sill of the sash frame.

' in which inserted one margin. of a strip of fabric 8. The body of the metal strip 6, as well as the folded margin 7, thereof,,is punched at a plurality of points as indicated by the reference numeral 9, to indent the metal into engagement with the margin of the fabric strip to insure positive engagement thereof within the metal strip. The other margin of said metal strip is bent at an angle as clearly shown in Fig. 5, and is provided with a number of slots 10, at points therealong .aflording substantially a plurality of independent resilient members or leaf springs 11, which act as a reinforcement for the fabric 8, when the same 15 bent outwardly due to contact with the surface of the sash 5. The weather strip is held upon the casing by means of screws 12, as shown in Fig. 1, and as shown in lz igs. E2 a'nd 3, the outer surface of the ash 5, may be provided with a shallow groove or recess 13, extending therealong adapted to receive the margin of the fabric 8, projected thereinto.

1n the modified form of device shown in Figs. 6, 7 and 8, l have shown the weather strip as consisting of a strip of metal 14, with one margin thereof folded over upon the margin of a piece of fabric 15, as designated by the reference numeral 16, and with the other margin normally angled inwardly and slotted to afiord a plurality of resilient members or leaf springs 17. '1 he strip with its associated fabric sealing means is attached by means of screws 18, to the outer surface of the stile 19', of a window sash extending over a longitudinal groove or recess therein into which projects a tongue or stop 20, integral with a portion of the window frame and a member 21, is secured to the Window frame and holds the tongue 20, from springing inwardly.

In Fig. 9, l have shown the weather strip of lfiigsfi, 7, and 8 connected on the under surface of the bottom rail of the sash 5, of

Figs. 1 to 5, to bear upon the sill of the frame when the sash is closed.

The operation is as follows:

When the device is in use it is attached upon the stop 4 of the window casing in a position wherein the fabric 8, bears in the groove or recess 13,.provided on the sash 5, and the fabric is reinforced and held thrust closely against said sash by the reinforcement afforded by the resilient members 11, formed on said strip in which the fabric is secured. As a result, when the sash is raised or moyed into open position, the fabric portion 8, springs inwardly below the sash beyond the normal plane of contact with the sash as clearly shown in Fig. 3,

' but, however, again springing outwardly into close contact with the wall of the recess 13, when the sash is again closed.

In the modified form of device illustrated in Figs. 6 to 8 inclusive, the resilient weather strip element bearing upon the tongue 20, inte'rfitting with the sash, thrusts the entire sliding sash outwardly in close contact with the 'inner surface of the tongue 20, thus holding the sash snugly against rattling in the frame.

Due to the fact that in all of the constructions shown, the reinforcement consists of a plurality of resilient members, it is evi dent that the same is capable of readily adapting itself to irregularities "of construction or other inaccuracies such as occur on the surface of contact with the sash or frame, so that a close seal of the weather strip with the sash is afforded at all times.

I am aware that various details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. ,A weather strip of the class described comprising a metalstrip, one margin thereof folded inwardly to afford a recess, a strip of fabric engaged in said recess, and the other margin of said strip bent outwardly and slotted to form a plurality of leaf springs affording a plurality of resilient re inforcing members for the pro ect1ng mar gin of said fabric strip.

2. A device of the class described comprising a metal strip, a strip of fabric engaged therewith and a plurality of resilient leaf spring members integral with said metal strip to reinforce the projecting margin of the fabric strip.

3. In a device of the class described a metal strip, one margin thereof folded inwardly to afford a recess, a strip of fabric engaged in said recess, said metal strip and inturned margin thereof punched from the exterior surface to indent the metal into en'- gagement with-the fabric strip to retain the same engaged therein, and a plurality of angled resilient leaf spring reinforcement having a" plurality of slots therein extending through the outer edge affording a plu rality of resilient reinforcement leaf spring members for the projecting margin of said strip of fabric,

5. The combination with a window frame and its sash, of weather stripping means connected therebetween comprising a strip of fabric, a plurality of resilient members associated therewith to thrust the same into sealing relation and a tongue connected to the frame and interfitting with the sash against which the sash is thrust by the resilient members.

6. The combination witha window frame and its sash, of a tongue on the window frame, weather stripping means secured upon the sash and disposed over a groove therein in which the margin of said tongue extends, a member secured to the frame bearing against the inner surface of said tongue to hold the tongue from springing iiwardly, and a plurality of resilient elements forming a part of said weather stripping means acting to draw the sash firmly against the tongue.

7. The combination with a window frame and its sash having a longitudinal groove in the stilesthereof, of a tongue on the window frame fitting in'the groove in said sash, a member secured to the frame and bearing against the inner surface of said tongue to hold'the same from being thrust inwardly and weather stripping means of resilient nature mounted on the sash overlapping the groove therein and bearing against the outer surface of said tongue to draw the sash closely against the tongue to seal the sash in the frame.
