mrpnovnn WEATHER-STRIP roRno-ons AND wmnows.

The Schedule referred to in these I etters Patent and making part of the same.

drawings, in which Figures 1 and 2 are front and rear views of a weatherstrip made in accordance with the said invention.

Figure 3 is a transverse section of the same.

This invention relates to that class of Weather-strips in which vulcanized India rubber, or its equivalent, is

secured in a'strip or moulding of wood, and extends or projects out from it, so that when said moulding is attached, forinstance, to the lower part of a door, the projecting strip of India rubber may have its edge resting on the threshold of the door-frame, the purpose of the same being to prevent air and dust from making their way underneath the door, and into the apartment to which such door may belong.

One object of the invention is to produce a weatherstrip in which the strip of vulcanized rubber, or other elastic material, may be held more securely and tightly than has heretofore been practicable; and a second object is to so construct the weather-strip that air and dust may be effectually prevented from passing through the joint or crack, between the strip and the door, or other part to which it is afiixed.

To this end the invention consists- First, of a weather-strip, composed of two strips or piecesof wood, or like material, and an interposed projecting strip of rubber, united by tacks, or otherwise, substantially as hereinafter set forth.

Second, in the employment, with-a weather-strip, of otherwise ordinary or suitable construction, of India rubber, or equivalent elastic material,.held in and arranged to project from that face of the weather-strip in contact with the door, or other part to which said strip is affixed.

Third, in minor features of construction, to be hereinafter described. r

The manner in which the invention may be carried into effect is shown in figs. 1 and 2, wherein an elastic strip, 0 o, is interposed and held between two strips or pieces of wood, a b, which constitute the moulding or main portion of the weather-strip, the said parts being united by. brads or tacks, e, or by other suitable means.

It will be seen that the one strip of rubber, c, in this case, passes through" its holder or moulding, and extends therefiom in opposite directions, so as to project from both faces of the moulding.

. The shorter face of the moulding, with its projecting rubber, is designed for the uses to which ordinary weather-strips are put; the longer or rearface of the moulding, from which the rubber also projects, is intended to be laid against the door or other part to which the weather-strip is to be afiixed.

The part a, of the holder or moulding, shouldbe rebated lengthwise, in rear of the upper external portion of the rubber strip, shown at (Z, fig. 3, where it will be 'seen that the whole device is triangular, or

nearlyso, in section. This rebate, when the weatherstrip is laid against a door, and confined thereto by means of screws or like means, enables the said upper external portion of the strip 0 to fall back, and allow.

the rear of the two parts a b, of the moulding, to be brought in close contact with the door.

, The'upper part of the strip a, by its elasticity, will be borne close again st the door, and thus prevent any current of air from entering the apartment by passing between, the moulding and the door.

By forming the weather-strip of two pieces of wood, v

- employed for thepurpose, pass'through the rubber or. I

not; for in any event such fastening-devices will bring I the two pieces of the moulding tightly together, and

thus cause them to graspand compress the rubber.

In weather-strips in which the wooden moulding consists of one solid piece, grooved to receive the rubber, the latter cannot be thus clamped, but must be held in place by cement, glue, or small brads, which, in themselves, are insuflicient to retain it securely in place for any considerable length of time; but by the present invention, so long as the moulding lasts, the rubber is clamped firmly and tightly, and the. difficulties heretofore experienced are thus obviated.

What is claimed as the invention of the said ISAAC- F. A; A. Iaznon is as follows:

, 1. A weather-strip, composed of two strips or piecesof wood, and an interposed projecting strip of vulcanized rubber, or equivalent elastic material, united by tacks, or otherwise, substantially as herein set forth.

2. The employment, with a'weather-strip of otherwise ordinary or suitable construction, of vulcanized.

rubber, held in and arranged to project from face of the weather-strip in contact with the door or other part to which said strip is affixed, substantially as and for the purposes herein set forth.

3. The improved weather-strip, as made with the strip of elastic material or India rubber, c c, to project in opposite directions from the two faces of the divided holder or moulding a-b, substantially in the mannershown and-described.

4. The combination, with the elastic strip, projecting from the rear face of the moulding, as described of the rebate cl, made in the moulding, and arranged, with relation to the said elastic strip, substantially as In testimony whereof, we have hereunto set our hands before two subscribing witnesses.
