lMPR'ovEMEN-r IN wEATHEmsTRIPMoLmNe.

Specifica-tion forming part of Letters Patent No. 34,455, dated February 1S, 1862.

` and I do hereby declare that the following is a full, clear, and exact description ofthe same,

reference being had .to the accompanying drawings, which form part of this specification, in which-- Figure 1 represents a door and frame having the improvement applied. Fig. 2 shows it applied to `a picture-frame back. Fig. 3 shows the back of the molding.` Figa shows the face 01j elastic side. Figs. 5 and 6 are crc-ss sections. Fig..7 is a sectional diagram showing the device applied to a window. The object of my invention is to provide an efficient and permanent contrivance for excluding dust, air, moisture; light, head, cold, &c., from crevices er apertures around doors and windows or wherever in general crevices or apertures exist which itmay be desired to close up. l

To this end I employ felt, rubber, or other substance havingthe quality of yielding and adapting itself to unequal surfaces, and back the same with a suitably rigid material-fsuch as wood or metal-to support and maintain the felt in place,and these two are conjoined in substantially the manner hereinafter specified.

v My improved molding is applicable chiefly inh situations where the surfaces adjacent to the aperture te be closed are at right angles to each other. A

In all devices heretofore used the rubber is inserted and secured in a shallow groove in the edge of theem-olding, and the rubber is not' only liable to become unfastened whenA the molding is accidentally split in the nailing of p l it on and otherwise, and thus rendered ineficient and useless, but is also objectionable in furnishing but one edge or surface capable of yielding and adjusting itself to the inequalities ofthe surfaces to which the device is applied, so lthat the cold or dust, &c., as the case may be, though quite effectually excluded from the aperture from one side, is allowed to enter moreorless at the other, andhence the device only partially remedies the. evil it is designed to cure. In order to obviate or overcome these diiiiculties and objections and pro duce a perfect thing, the felt, rubber, or other elastic substance in myimproved contrivance is so secured to the backing or rigid part vas to expose both the edge and side of ,the felt, and thus providesl against all lcontingencies by presenting to the contact of both the contiguous surfaces a substance possessing-the capacity of self-adaptation thereto. The

same peculiarity of structure admits the nails used to fasten it on through both the felt and the wood or metal, so that if the latter be come injuried or mutilated the feltwill still retain its place, all which will hereinafter more fully appear.

To enable others to make and use my in vention, I will proceed to describe the same andthe mode of its application and use.

I usually make myimproved weather-strip molding of a strip of sheet metal A,'(see annexed dra-wings) doubled or folded over on .a strip of felt, rubber, or.other elastic substance B. The metallic part may have beads or corrugations longitudinally for stiffening purposes. That part 1 of the metal folded over on the felt is jquite narrow, and has its edge turned down or pressed into thcfelt Ato prevent the latter from escaping from the fold, and in addition the metal may be creased or indented on the opposite side 2. The narrow fold 1 leavesl a Width of felt of nearly the same dimensions as the metallic side of the molding, and said felt extending beyond the upper edge of the metal shows a feltmargin 3v on the metal side nearly as wide as the metal margin on the felt side. Fig. 3 shows the former and Fig. 4 the latter.

In applying the molding the elastic or felt Fig. 1 shows a door and frame with the moldin g applied. The .line cis the usual rabe 2 d i 34,4ss

bet receiving the edge of the door, and the ine a," represents the edge of the felt or rubber. The molding is also used for rendering show-eases, picture-frame backs, dse., dusttight IFig. 2 shows 2LV picture-framebztck. The molding is fastened ou the frame with the felt edge pressing against the picture back. Itfis also applicable to apertures in fiat surfaces, and forsuch places the mold-ing is sometimes made with the metal folded over both edges of the felt.

Many other forms could beA illustrated;v v

The new manufacture of improved weatherstrip molding, substantially is described. I
