1 Claim. (Cl. Ztl- 69) This invention relates to draft seals, is particularly concerned with draft seals for doors, and is more particularly concerned with seals adapted for silencing.

In the prior art there are door seals of many different descriptions and of many different structures. Most of these door seals are made of very thin metal sheets, usually made of copper or brass, and are either tubular in structure or are in the shape of substantial crescents. When the door is closed and comes in Contact with the metal seal, the draft sealing is dependent on the resilience of the metal tube or the shape of the seal. Since such seals may serve well in forming a close contact of the door with the seal and the door casing when they are rst installed, metal will soon become fatigued and will lose its resilience and there ceases to be an intimately close contact of the door with the seal.

There are also other types of seals which do rely on rubber or the like materials for forming the contact but these seals need to be cemented or some such means need to be resorted in securing the seal to the molding and the door casing. There are also other and serious objectionable features due mainly to the structural design of such seals.

It is therefore an object of the present invention to provide a door seal. It is still a further object to provide a door seal adapted for providing silencing. It is a further object of the present invention to provide a door seal fabricated of rubber or the like resilient material. A still further object of this invention is the provision of a holder for securing the resilient material. A further object is the provision of the holder which aifords ease in securing the said resilient lmaterial with the door casing. A still further object of the present invention resides in the provision of a means for securing the resilient member of the seal without the need of cementing. A further object is the provision of a door seal having means for securing the resilient member to a door casing by means of locking the same with the molding of the seal.

I have now discovered and invented a door seal comprising an elongated resilient member, the said resilient member having a body and a base, the said body and base being integral with each other, the said body being hollow, a molding, the said molding having one at portion to conform with and be secured to a door casing, and a base portion to conform and secure the said resilient member, and means for securing the said molding to a flat surface, and I am now able to avoid the disadvantages of the prior art and am able readily to accomplish the objects set forth.

While some of the more outstanding features, and advantages of this invention have been hereinbefore indicated, others will become apparent from the following disclosures, taken in conjunction with the accompanying drawing, in which:

Fig. 1 is a front view of a conventional door as seen when viewed from the outside. The heavy lines represent the seal of my invention.

Fig. 2 is a partial view of the door casing.

Fig. 3 is a sectional view taken along the line 3--3 of the Fig. 2, showing the sealer or molding made of metal, and showing the resilient material encased therein.

Fig. 4 is a sectional view showing the resilient material, and the molding made of wood, with the rcsilient material locked in place.

Fig. 5 is a sectional viewv showing a modification of my invention having a wood molding. y y

Fig. 6 is a sectional view showing a modication of my invention having a metal molding.

The resilient member 10, shown in the Figs. 2, A3, 4, and 6, and the resilient member 16 which is shown in the Fig. 5 is preferably made of rubber, and for best results I prefer that it is made of rubber of number-40 durometer. It will be noted that the members 10 shown in the various figures are identical with each other. The moldings used to secure the members 10 vary in structure. The resilient member 16 which is shown in Fig. 5 is a modication of the resilient members shown in the other figures. It will be noted that the molding 17 is fabricated to conform to the shape of the base 20 of the resilient member.

The resilient member comprises of an elongated body 10, and the base 19. In the instance of the modified form of my invention shown in the Fig. 5, the resilient member comprises the elongated body 16, and the base 20. It is obvious that the elongated body 16, and the base 2t) are integral with each other. It is likewise obvious that the elongated body 10, and the base 19 of the other members shown in the Figs. 3, 4, and 6 are integral with each other. Thus a smooth transition surface is provided between the body 16 and base 19 on one side of the elongate body 10 and accomplishes tangential connection with the substantially hemispheric portion of the body 10.

I want particularly to point out that the elongated body of the resilient members 1l) and 16 are rounded laterally at the top surface to permit the corner of the door to be cleared when the door is being closed. This will be seen in the right-hand drawing of the Fig. 3. It will be noted, however, that when the door is finally closed that a portion of the rounded body of the resilient member extends toward the door, and that this portion is compressed by the door to form a tight seal with the door and the door seal of my invention.

To add to the resiliency of the

resilient members

10 and 16, the elongated head is formed hollow lineally throughout the entire head and is of substantially hemispheric shape in cross section as indicated, for example, in Figure 4.

The metal molding 13 is made of a strip of sheet metal folded back upon itself, and with the two edges of the metal further folded back and being substantially rounded.

The metal molding 18 shown in the Fig. 6 is made of a single strip of sheet metal rounded at each of its ends to prevent damage to the door frame and to the resilient member.

Referring particularly to the form of my invention as shown in Figs. 3, 4, and 6, it will be noted that the resilient member 10 is secured to the door casing 11 by means of being locked frictionally between the door casing and by the lip portion of the base locking matingly with the molding. The manner of locking of the device shown in the Fig. 5 is substantially the same as in the other iigures mentioned above, but the base of the resilient member extends further away from the base proper, and is L-shaped-like.

In actual use of the seal of my invention the resilient member 10, and in the case of the modified form, the resilient member 16, is placed contiguously with the molding, the two members are then placed against the door casing by means of nails or screws holding the molding. It will be noted that resort need not be made to cement or other securing means other than that described above. The resilient member is locked in place by its base, the molding, and the door casing.

When the moldingis secured in place to the door casing the

resilient members

10, and 16, are securely held in place due to the structural design of the resilient members and the molding conforming one with the other.

The Fig. 3 shows the same invention except that the molding 13 is made of metal instead of wood, and the said molding is secured to the casing 11 by means of the screw 12.

The Fig. 6 shows another modified form of my invention having the same resilient member 10 as is shown in the Figs. 3 and 4, and the molding 18 is slightly different in design. It will be noted that the middle portion of the molding is bent down to contact the door casing.

The Fig. 1 shows a conventional door 14, and shows the resilient member 10, and the door casing 11.

I wish to point out particularly that the device of my invention is used as a sealer to prevent the passage of drafts, dust, smoke and odors, but it also serves as a silencer. Since the rubber members are resilient, the shock of the door hitting against it is broken, and there is less wear on the door and the casing due to the impact of the door.

I wish further to point out that my invention is not limited in its use in conjunction with outside doors, since I find it extremely advantageous for use for inside doors. For example, I nd my invention very useful in conjunction with inside hospital doors. And I nd it to great advantage to use my invention in connection with windows.

Having clearly set forth the construction, utility and advantages of my invention I wish particularly to state that it will be apparent that changes in the details of the construction and arrangement of the various members of the invention may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.

I claim:

A weather seal for door trim held against a fiat frame surface including: an elongate member of resilient material having in cross section throughout its length a body consisting of a hollow portion of substantially hemispheric configuration being connected integrally at its points of juncture to a solid tongue portion on one side with the said hemispheric portion, said connection describing a smooth transition surface and being grooved on the other side where said tongue joins said body; and a molding having a lip longitudinally along one edge mating in the said groove between said base portion and said tongue to grip said tongue in longitudinal position against said at surface; and securing means through said molding attaching said molding to said llat frame surface.
