WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 710,478, dated October 7, 1902. Application filed December 5, 1901. Serial No. 84.842 (No model.)

To (tZZ whom, it ntay concern:

Be it known that 1, MILES K. LITTLE, a citizen of the United States, residing at Camden Point, in the county of Platte and State of Missouri, have invented certain new and usefullmprovements in Weather-Strips,of which the following is a specification.

My invention relates to improvements in weather-strips for doors, its object being to provide a hinged strip which is raised when the door is opened and thrown down when the door is closed, thus preventing wind, dust, or water from passing under the door. This object is accomplished by a construction and combination of parts, all of which will be fully described hereinafter and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional view of my invention with the door closed. Fig. 2 is a vertical sectional view with the, door open. Fig. 3 is crosssection on the line 3 3 of Fig. l with the door closed. Fig. 4 is a cross-section on the line 3 3 of Fig. 1 with the door opened.

Referring now to the drawings, the numeral 1 indicates the door-frame, and 2 the door, which is provided with a flange 3, which extends transverse the lower portion of the door and is rigidly attached thereto. Hinged to the door below and adjacent the flange 3 is a thin metallic weather-strip 4, which extends below the door-sill when the door is closed, as shown in Fig. 1.

In the lower portion of the door I provide a housing or recess 5, which has a longitudinal opening 6 for receiving a headed pin or rod 7, the rod 7 being held normally outward by the spring when the door is opened, and when the door is closedthe projecting end of the rod 7 is brought in contact with the plate 8, secured to the door-jamb, thus forcing the rod inwardandcompressingthespringG. Hinged within the recess 5 is a bell-cranklever 9, one arm of which extends through a longitudinal slot in the rod 7, this arm being curved, as illustrated in Figs. 3 and 4.. The-numeral 10 designates a \l-shaped plate with two inwardly-extending perforated lugs. This plate is pivoted on the same pin to which the bellcrank 9 is hinged. The short arm 11 of the bell-crank engages the under side of the V- shaped plate 10 and serves to force the said plate out for raising the Weather-strip 4: when the door is opened.

From the above description it will be seen that when the door is closed the outer end of the rod 7 abuts against the plate 8, which carries the arm 9 of the bell-crank inward, when the plate 10 will enter a recess 12, thus allowing the weather-strip to drop and assume a vertical position, the strip extending below the bottom of the door, as shown in Fig. 1.

lVhen the door is opened,the rod 7 is gradually released, the spring 6 forcing the rod out and carrying the arm 9 forward, when the short arm 11 of the bell-crank will force the plate 10 out, which in turn raises the weather-strip gradually as the door is opened, so as to permit the same to readily pass over the carpet or other obstruction.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination with a door ofa weatherstrip pivoted thereto,an endwise-movable bar carried by the door, aV-shaped member pivoted to the door, and adapted to swing under the weather-strip and a bell-cranklever pivoted to the door and having one end engaging the V-shaped member and the opposite end engaging the said bar, substantially as described.

2. The combination with a door ofaweatherstrip pivoted thereto,an endwise-movable bar carried by the door and having an opening therein, a V-shaped member pivoted to the door and adapted to swing under the weatherstrip, anda bell-crank lever pivoted to the door and one end engaging the V-shaped member and the opposite end entering the openingin the said bar, substantially as described.

3. The combination with a door having a recess in one edge thereof, of a weather-strip pivoted to the door above said recess, a spring within said recess, an endwise-movable bar within said recess and bearing against said spring, said bar-having an opening intermediate its ends, a V-shaped member pivoted to the door beneath the weather-stri p and adapted to engage the under side thereof, and abell-cranklever pivoted to the door and having one end adapted to engage the said \I- therein, a V-shaped member pivoted to the door and swinging under the weather-strip, and a bell-crank lever mounted on the same pivot as said member, and one end engaging the said V-shaped member and the opposite end entering the recess in the bar, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
