WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 635,708, dated October 24, 1899.

Application filed January 11,1899- Serial No. 701,860. (No model.)

To ctZZ whom it nmy concern.

Be it known that we, MORTIMER YAKLEY and NEWTON F. PRUDDEN, citizens of the United States, and residents of Chelsea, in the county of VVashtenaw and State of Michigan, have invented certain new and useful Improvements in Weather-Strips; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawin gs, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a perspective view showing the invention as in application. Fig. 2 is a vertical transverse section of the invention as in application with the door closed. Fig. 3 is a detail view, partly broken away, of the molding and spring-plate.

This invention is designed to provide a simple, efficient, readily-applied, durable, and comparatively inexpensive weather-strip of improved character and which is adapted to automatically take up or adjust itself to the wear of the parts.

iVith these objects in view the invention consists in the novel construction and conibination of parts, all as hereinafter described, and pointed out in the appended claim.

Referring to the accompanying drawings, the letter A designates adoor, and B a doorframe and sill or threshold.

0 designates a molding of peculiar form which is secured to the outer face of the door a short distance above its bottom edge and which extends transversely the full width of the door. This molding consists of an upper horizontally-projecting portion having a plane under face and a lower depending portion extending downward from the under side of said upper portion and leaving a space or recess D between itself and theface of the door. The lower part of this depending portion is formed with a rounded face 0, as shown, for the purpose hereinafter described. IVhile this molding might be made in one piece, we have usually preferred to make it in two separate pieces, the upper portion being secured to the door by screws 0', while the lower portion is secured by long screws 0 which extend across the upper portion of the space or recess D and into the door. By this construction the upper portion of the molding is relieved from strain and is less liable to split or break.

E designates an edgewise-disposed springplate which is secured to the door within the space or recess D and which terminates at its free end, at about the center of the door, in a shoe F, at right angles thereto, of triangular form,with its inclined face opposite the rounded face 0 of the molding, as shown. This shoe F is at right angles toits plate. This springplate is secured to the door, near the hinged edge of the latter, being thickened and perforated, as indicated at c, to provide seats for the securing-screws. The inner face of said thickened portion is beveled, as shown, in order to cause the plate to diverge somewhat from the face of the door throughout its length. In order that the said plate may always be secured to the hinged edge portion of the door, right and left made plates are provided.

G designates a sill-plate having fiat upper and lower faces and which is of a length equal to the width of the doorway. This plate is pivotally connected to the sill or threshold at its outer edge by means of staples g, which engage perforations in the plate with sufficient looseness to permit the plate to be turned entirely over, if desired, in order to facilitate cleaning the sill. Said plate at its central portion is bent upwardly, as indicated at g, to form a lip or crown adapted to be engaged by the point of the shoe as the door closes.

When the door is open, the plate G lies fiat upon the sill or threshold out of the way and as the door swings to the point of the shoe rides under the lip or crown g, thereby raising the said plate into an inclined position, with its free edge portion resting on the inclined face of the shoe and its upper face bearing against the rounded lower face a of the molding C. It will be readily seen that owing to the wedging action of theshoe the said plate G is caused to bear tightly against said molding and that owing to the rounded face of the latter a perfect bearing is provided for said plate at any angle which it may ICO assume. Said plate therefore forms an efficient guard not only against the entrance of rain or snow underneath the door, but also excludes cold air. It will also be seen that as the plate G is wedged tightly against the molding C by the action of the shoe the pressure of said plate against the molding tends to close the door tightly to its seat in the casing instead of tending to hold the door away from its seat, as is the case with many other weatherstrips. The spring action of the plate E and the wedging action of its shoe will automatically take up any wear of the parts. The said plate E being seated within the space or recess D is concealed from view as well as protected from the weather. We are also enabled to use aplate of sufficient length to obtain a strong and durable spring action, and being always secured to the hinged edge portion of the door its action is supported by the door where it is best able to receive and bear it.

In applying the invention to a door the latter is first closed and latched. The spring is then secured thereto, as hereinbefore described, and in such position that the lower face of the shoe just (but freely) clears the sill. The sill-plate is next laid in place on the sill, resting on the inclined face of said shoe, which at this time standsout from the door to the full extent of the spring action of the plate E, the free edge of the sill-plate being placed against the plate E. It being made certain that the free edge of the sill-plate is equally distant from the door at bot-l1 ends, said plate is nextstapled to the sill or threshold. It is then turned back away from the door and the spring and shoe are pressed back with the hand to their full extent toward the door and are held in this position by driving In a weather-strip, the combination with a fiat sill-plate pivotally secured to the sill or threshold at its outer edge portion, of the molding secured to the door and having the depending rounded portion separated from the door by a space or recess, the spring-plate within said space or recess and secured to an edge portion of the door by one end portion, and having its opposite extremity formed with a triangular shoe at right angles thereto projecting outwardly underneath said molding at the central portion of the door, and having an inclined edge adjacent to the rounded face of the molding, said shoe being adapted to ride underneath the sill-plate and raise the same to inclined position with its free edge portion within said space or recess and its upper surface in contact with the rounded face of the molding, substantially as specified.

In testimony whereof we aflix our signatures in presence of two witnesses.
