i Letters Patent No. 65,781, dated June 11,125.67. I v I mrnovtn WEATHER-STRIP.

To ALL `WHOM 1T MAY CONCERN;

Be it khownthat JEREMY B. WARDWELL, of Georgetown, in the county of Washington, and District of Columbia, have invented a. new and improved Weather-Strip; and I do hereby declare the following to `be a. full'and exact description of the same, reference being had to the accompanying drawings, which are made part of this specification, and in Which Figure 1 is a front elevation.

Figure 2 is a vertical transverse section.

Similar letters of reference indicate corresponding parts in the two figures.

The strip is formed of a plate of India. rubber, and, with the springs bearing' upon its upper surface, is

.attached to a horizontal rotating shaft, moved -by the closure of the door, avstud on'the door-casingimpinging upon a lug on the shaft. ,e n

In the drawings, A is the door-casing'B the threshold; C the door, Whose lower end is hollowed ont to receive the strip and its operative devices. D is a. horizontal shaft, having its bearings in `the upturnerl ends of the pl'atc E, which forms the lowervedge of the door. This plate has an opening, through which the stripl` projects when the shaft D is rotated bythe contact of its lug G with the projecting stud H ou the door-casing when the door is closed. `When the door is opened the strip rises as the shaft D is rotated in the other direction by the springs I, which are connected by wires to lugs 'on the shaft D. The India-rubber strip Fis clanped lbetween plates K K, which are attached to the shaft D, and springs L, Sto., also attached to the shaft, bear upon the strip F near its edge, and pressit down against thc threshold and into any` inequalities thereon, so that o. vknotty or uneven step will not permit the passage of the air in the hollows of the undulations. By this means the crevice or gap under the door will be thoroughly stopped, which cannot be the case with an uneven doornsill when a straight weather-strip is applied.

Having described my invention, what I claim as new, and desire to secure by Letters 'Patent, is-l- I claim the weather-strip, provided with the springs by which the elastic strip F is made to conform 'to the irregularities of the threshold, as herein described for the purpose specied.

JEREMY B. WARDWELL.
