WEATHER-STRIP.

SPECIFICATIQN forming part of Letters Patent No. 349,787, dated September 28, 1886,

Application filed June 26, 1886. Serial No. 206,355.-

To all whom it may concern.-

Beitkuown that I, JOHN W. FARR, a citizen of the United States, residingat Marion, in the county of Grant and State of Indiana, have invented a new and useful Improvement in Weather-Strips, of which the following is a specification.

My invention relates to an improvement in weather-strips for doors; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of a portion of a door and door-frame provided with a weather-strip embodying my Fig. 2 is a vertical sectional Fig. 3 is a detail reverse anism.. Fig. at is a perspective View of a portion of a weather-strip.

A represents the door-frame, the sill of which is provided with the usual thresholdstrip, B.

0 represents the door, which has one edge hinged in one side of the door-frame in the usual manner. The bottom edge of the door is cut away on one side, thereby forming a recess, D, in which is located the metallic weather-strip E, which extends entirely across the bottom edge of the door, and has its outer edge. turned downwardly, and thereby forming the lip e. The said weather-strip at its inner edge is provided at its extremities with projecting trunnions e, which are journaled in the lower edges of metallic plates F, that are secured in countersunk recesses in the edges of the-door, at the lower side of the same,

by means of screws. The inner edge of the strip beyond the pivot-point is turned upward, as at m, and fits in a channel, b, out out of the door at the end of recess D. From this construction it will be readily understood that when the door closes the weather strip is adapted to drop,so as to cause the lip e to bear upon the inclined outer side of the strip B, and thereby entirely close the crack at the lower edgeof the door.

H represents an inclosing-case, which is secured on the outer side of the door,near the outer edge of the same, by means of screws I.

The said case is provided at its edges with an (No model.)

inwardly-extending flange, h, and formed with the side flanges of the said case are the inwardly-extending ears h, which project into a horizontal recess which is made in the outer side of the door. A vertical opening, K, is made in the case H, at the outer edge of the same, and near its lower end.

L represents a rock-shaft, the ends of which are j on rnaled in openings in the ears h. From the said rock-shaft, at one end of the same,

' projects a tappet-arrn,L,the outer end of which is curved downwardly, andpasses through the slot K and projects from the outer side of the case. At the opposite end of the said rock-shaft is an arm, L". A connecting-rod, M, has its upper end attached to the said arm, and the lower end of the said connecting-rod is attached to the weather-strip E.

N represents a coiled spring which is placed on the shaft'L. One end of the said spring is attached to the said shaft, and the other end of the spring bears against the inner side of the case II. The function of this spring is to turn the rocl -shaft so as to cause the tappetarm L to normally project from the face of the case H, and also to raise the arm I and thereby normally raise the weather-strip.

0 represents a casting or frame which is secured to the inner side of the door-frame at the edge against which the door closes. At the projecting end of the said case-of the said casting or frame is journaled a roller, P.

The operation of my invention is as follows: When the door is closed, the tappet-arm L strikes againstthe roller 1?,and is thereby depressed, causing the shaft L to partly rotate, and thus lower the outer end of the arm L and thereby lower the free edgeor lip e of the metallic weather-strip, so as to cause the latter to bear upon the upper inclined outer side of the door-strip B, and thus effectually close the crack at the bottom of the door. As soon as the door is opened the tappet arm Lis disengaged from the roller 1?, thereby causing the spring N to reverse the movement of the rock-shaft and raise the lip e of the weatherstrip, so as to enable the latter to clear the door-strip B. p

As the rod M is connected to the weatherstrip in advance' of the pivot-point, it will be I seen that the forcing of rod M downward causes the inner edge of the strip to work up ward, with the lip m fitting in the channel Z). This lip thus serves to limit the movement of the strip, and also to exclude drippings from the door from obtaining access to the room, as will be readily understood.

Having thus described my invention, I claim- 1. The case H, adapted to be secured to the door, and having the slot K, in combination with the horizontal rock-shaft L, journaled within the case, the tappet-arm L at one end 3. In combination with the strip E, pivoted to the lower edge of the door, and having the lip m on its inner edge fitting within a recess of the door, the rod M, connected to the strip in advance of the pivot-point, and operating means for the rod M, whereby when the latter is operated the front end of the strip is forced down and the lip m is thrown up into the recess of the door, said lip limiting the downward movement of the strip, and also serving to exclude drippings from the door, as set forth. Y

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

JOHN w. FARR.
