SPECIFICATION forming part of Letters Patent No. 297,636, dated April 29, 1884.

Application filed J annary 30, 1884. (No model.)

To all whom, it may concern:

Be it known that I, JOSEPH F. RowLE'rT, a citizen of the United States, residing at Richmond, in the county of WVayne and State of Indiana, have invented certain'new and useful Improvements in WVeather-Strips, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to that class of weatherstrips intended to be used upon doors in dwelling-houses, and which are operated by the closing of the door.

My invention consists in a counterbalance- I 5 weight attached to the hinged strip of the apparatus, serving. to hold the same in the required position.

In the drawings, Figure I is a vertical cross-section of the lower portion of the door,

showing the weather-strip as attached when the door is open. Fig. 2 is a similar-sectional view, showing the door closed and the weather-strip in position to protect the aperture between the bottom of the door and the door-sill. Fig. 3 is a rear elevation of the weather-strip, showing the shape and posi tion of the counterbalanceweight, also the stop used to check the motion of the hinged strip. I

In Fig. 1, A represents the edge of the lower )ortion of a door. B is a strip equal in length to the width of the door, having a plain surface on the side attached to the door, to which it is secured by screws, or in any other suitable way, near the bottom of the same. The outside surface of the strip B is irregular, and in the form of a molding, the lower edge of which forms a projection sufficient to overlap the strip 0, as shown at F, Fig. 2.

C, Fig. 1, is a hinged longitudinal strip corresponding in length to the fixed strip B, and of suitable width to constitute a sufficient protection to the aperture between the door and the sill, and is hinged in a suitable manner to the lower outer edge of the fixed strip B,

(shown at G.) The upper edge of the hinged strip 0 is supported, when the door is open,

by a stop or catch, E, where it is held in position above and free from the floor by the action of the counterbalanceweight F, which is a longitudinal metallic bar or strip attached to the inside upper edge of the hinged strip 0 by means of screws or nails L, as shown in Figs. 1, 2, and 3. The metallic bar Fserves to prevent the strip 0 from warping or twisting, and also assists in holding it in a horizontal position free from-the floor when the door is swinging.

J, Fig. 2, represents the door-casing, which is at right angles with the face of the door when it is closed.

H,'Fig. 2, is a circular knob or button secured to the casing J in such position that in swinging the door toward its closed position the outer edge of the hinged strip 0 comes in 6 5 contact with the lower circular edge of the button H, and is pressed down so as to give the strip Gnearly a vertical position, thus closing the aperture under the door, and retaining the strip 0 in that position.

In Fig. 3, B represents that surface of the nod strip which is in contact with the door. 0 is the hinged strip. F is the longitudinal metallic counterbalance-weight, and I is .a catch-plate that comes in contact with the stop E.

It will be seen that in the manufacture of my improved weather-strips they may be made of a length equal to the widest doors, and as the metallic counter-balance is made shorter than the whole length of the weatherstrip, the ends,-which are of wood only, may be cut off to fit narrower doors without otherwise changing the condition. The weight or counter-balance F extends nearly the whole length of the strip 0, by which the counterbalance acts upon the entire length of the strip. 7

I am aware that rotating strips with sockets on the ends and weights within the sockets have been used. This combination I disclaim. Nor do I claim a strip turning upon its own axis, to which a connterbalance is at tached.

Having thus fully described my said inven- In testimony whereof I affix my signature in tion, whatI claim as new, and desire to secure presence of two witnesses. by Letters Patent, is-- In combination with mold B, the hinged JOSEPH F. ROVLE'LT.

5 strip 0, the longitudinal metallic bar F, fastenings L, stop E, and projection or button H, \Vitnesscs: all constructed for the purpose as herein de- M. A. PEELLE, scribed. \V. T. DENNIS.
