My present invention relates to gaskets or Weatherstripping for doors and particularly the type whichv consists of ecovering fabric tolded upon itself end enclosing a pecking 3 element.

Gaskets of this general character have long been known in the ert,end have comprised "various arrangements of one or more soft iillers confined in a covering strip of w lahric or the like provided with e portion adopted to receive techs, nails, etc, for fe toning the gasket in operative position in a door jeinh. Such gaskets provide e teirly e'ficient seel when the is on the jeinh end the pecking materiel in the tiller is compressed thereh A fl found ion'ozi consider e eniciency c, i he obtained h co r} so 1 e nrior another end resilience he two n y es es to so to provide hetwee sin deed specs the softer and larger tiller compressed between the door end the jeinih to the thickness oi the smelier filler. in

Fi ure IL- is n perspective View, with one end 1n section, of a gasket constructed according to the principles of the invention;

Fig. 2 is a sectional View of s portion cl? 3 door and e gasket applied thereto, with the door open; and I Fig. 3 is a View similar to that of Fig. 2 hut bellowing the door closed against the 3am Referring now to the drawing, the reien ence numeral 1 designates a portion of the edge of any door, such for example as thet of a refrigerator, and 2 indicates the "ieinh against which it is adopted to close.

The gasket comprises a, covering iehric 3 of any sulteblekind, such for es oilcloth or equivalent textile erehiy provided with u herd, WEEBT'FLY surface, The covering fabric is folded upon itseli end encloses eiplureiity of tillers, least one of which is relatively l o' t or resilient, end at least one o: h is ient shapes so long as they exhibit the ditterenccs in size and dciormehility which is characteristic of my invention.

The covering fabric 3 is folded along its longitudinal center around the filler d which is confined therein loy a, line of stitching 6,

The fabric plies are then continued on oppreciebie distance in contact with each other to the line of stitching 7, beyond which they diverge to enclose the tiller 5. The fabric is brought together beyond the tiller 5 by the line of stitching 8, end the two plies are extended a substantial distance in contact with each other to provide a tacking flange or in, 9.

lhe gasket is applied in operative position to the edge of a door, or to a door jamb, by passing tacks, nails or the like through the tecking flange 9. The tendency among refrigerator manufacturers at the present time is to provide their doors with a metal flange spaced a slight distance away from the door proper, and it will be appreciated that the flange 9 may be readily inserted beneath such a. flange and thus secured in place. The remainder of the gasket, including the two filler enclosing portions, projects outwardly to about the edge of the door. as shown in Figs. 2 and 3.

When the door is closed against the jamb the filler at is substantially deformed, become ing elliptical in section, as shown in Fig. 3'. The sizes of the two fillers are so proportioned that when the door is fully closed and latched the filler 5 will be snugly engaged by both door and jamb under slight compression, and

tiller 4 will be deformed to an elliptical cross section having a thickness about equal to the dianiieter of filler 5.

It will be apparent from Fig. 3 that with the gasket in the condition there shown transfer of heat from one side to the other of the door which is sealed is prevented not only by the insulating fillers 4 and 5, but also by the very much more eflicient insulation provided by the dead air spaces formed between the two fillers and the door and jamb, indicated at 1-0 in Fig. 3. It will be apparent, therefore, that my present invention, by providing in addition to the solid non-conductor seals of the prior art the dead air space which I believe to be novel with me, affords a highly superior gasket. It is to be noted also that my present gasket is considerably more durable than those of the prior art, i. e., it

retains its high initial efiiciency even after very long periods of use. This will be clear from the following considerations.

From the beginning of use of the gasket, filler 5 is compressed slightly each time the door is closed, and by beingso compressed the extent to which the much softer filler 8;

.can be deformed is limited. Consequently, .in gaskets made according to my present invention, the soft, resilient filler 4 is protect-- I ed from the application of those severe compressive stresses which in the gaskets of the prior art soon cause induration and fibre eonsolidation and bring about steadily decreasing efficiency.

vI am aware of prior gaskets which include with a wicking filler a strand, roll or rod of flexible material for the purpose of stiffening the soft ,wicking, of which United States Patent No. 1,742,195 to Bosley shows a typical example. I make no claim to any such stiffening element, the essence of my invention being the provision of a dead air space between two sealing fillers, a feature not achieved by the association of a mere stiffening element with a wicking filler.

I am aware also of structures which contain a relatively large sealing filler and a relatively small bead separated by an intervening web of fabric, such as shown in the United States Patents No. 1,627,915 to Marshall and N 0. 1,713,268 to Dennis, and I make no claim to such combination, since it is of the essence of my present invention that the gasket have a plurality of scaling fillers which are adapted when in operation to provide between them a dead air space.

It is to be understood that various changes and modifications may be made in the practice of the present invention as exemplified in the specific gasket illustrated and described herein without departing from the principles thereof. Thus, for example, the fillers may be made of other materials than cotton wicking and rubber respectively, adhesive may be used to hold the plies of fabric together, the width of the web of covering fabric between the fillers may be varied somewhat, and other obvious changes may be made. All such modifications, however, to the extent that they exhibit the principles of the present invention as pointed out in the appended claims, are to be deemed within the scope and purview thereof.

Having thus described my invention what I claim and desire to secure by Letters Patent 1s:

1. A gasket adapted to be disposed between a door and its jamb having a fabric covering folded upon itself and enclosing a pair of fillers, one of said fillers being larger than the other and adapted to be compressed by closure of the door against the jamb to the thickness of the smaller filler.

.2. A gasket adapted to be disposed between a door and its jamb having a fabric covering folded upon itself and enclosing a pair of fillers, the fabric being secured to itself between the fillers to provide a connecting web of relatively wide area lying substantially in a plane which passes diametrically through both fillers adapt provide a dead air space on each side'of said web when the gasket is compressed between a door and its jamb.

3. A gasket according to claim 1 in which the covering material is continued beyond the smaller filler to provide a tacking lap or flange.

4. A gasket according to claim 1 in which the smaller filler is of rubber and the larger filler is of fibrous material, and in which the covering material is continued beyond one of the fillers to provide a tacking lap or flange.

5. A gasket according to claim 1 in which the covering material is continued beyond one ofthe itllCIS to provide a tacking lap or flan go. in testimony whereof I aiiix my signature.
