IMPROVEMENT lN'WEATHER-STRIPS.

Specification forming part of Letters Patent No. 170.534. dated November 30,1875; application filed October 30, 1675. l

To all whom it may concern:

Be it known vthat I, DANIEL DOAN, of Springville, in the county of Linn and State of Iowa, have invented a new and valuable Improvement in Weather-Strips; and I do hereby declare that the following is a' full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a front view of my weather-strip, and Fig. 2 is a sectional view of the same.

This invention has relation to improvements in weather-strips, which are applied to the lower edge of a door for the purpose of preventing Wind or rain and snow from penetrating into a building through the crack between the door and the sill.`

The nat-ure of the invention consists in combining, with an obliquely-slotted sheath rigidly secured to the door at or near its lower edge, an axially-rotating and endwise-movable rockshaft. sustaining the weather-strip and rotating in the said sheath, which shaft projects out beyond the hin ged edge of the door, and strikes against the jamb when the said door is closed, whereby a means is provided for automatically thrusting the edge of the strip against the sill with the desired effect. It also consists in combining, with the slotted sheath and the endwise-movable and rotating shaft supporting the weather-strip, a spring, arranged upon the said shaft within the sheath, and compressed by the endwise movement of the former occurring when the door is closed, which spring will react when the door is again opened, and will thrust the end of the said shaft out beyond the hinged edge of the door in proper The doorv may also be provided with 011e or more plates D, having a tubular lower end, through which and through the sheath is passed a cylindrical shaft, E. This shaft is endwise movable in relation toits bearingsUE,and it is 4provided with metallic arms d d', to the outer ends of which are hinged a weather-strip, F,

the construction of which will be hereinafter explained. Arm d projects outward through '1, both the shaft and strip fit snugly between the door-jambs c when the door is closed, but when it is opened a coiled, helical spring, S, arranged in the sheath, which had been compressed by the endwise movement of shaft E, will, in reacting, force the end ofthe shaft out beyond the hinged edge of the door, at the same time imparting to it a degree of rotation sufficient to raise the lower edge of the Dstrip from the floor. The eti'ect of the projection of shaft E, above described, is that in closing the door it will strike the jamb, and then receive end wise movement and axial rotation,.the latter causing the strip to vibrate vertically with its edge in close contact with the door-sill. The strip is, preferably, of metal, though it may be made of wood, and it is provided upon its under side with a leather, rubber, or other suitable flexible covering, t', which, when brought into contact with the sill, will render the joint of the strip therewith absolutely water and airtight. l

In practice also I propose to use an inclined apron, H, of any suitable material, which,

being secured to the door above shaft E and its attachments, will eectually protect them to open the door. In order to make the door equally weatherproof upon its topand lateral edges, as well as at its bottom, I have devised the following: The stop-rails n n at the top` tallic pins, o. These pins extend through per-` forations pmade in the stop-rails, and are held to their engagement therewith by being passed through a metallic plate, q, secured over perforations p, and an enlarged head, g, formed on the free ends of the said pins, which prevents their being drawn through the said plate. Strips I are forced out of the recesses i p p hereunto subscribed my name in the presence `of two witnesses.

by means of helical springs J, arranged on the said pins, and when the door is open will hold the said strips in this position; but when 1 the door is closed springs J will yield, allow the strips to enter into the recesses, and will hold them firmly againstthe door, thus shutting out currents of air, and preventing snow from drifting or rain from beating into a hall or apartment. i

H What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a weather-strip, the combination, with a tubular obliquely-slottedA sheath, C, of the rotating and endwise-movable shaftE sup-` porting the weather-strip, substantially as specified.

2. In combination with an endwise-movable and axially-rotating rod, E, and the obliquelyslotted sheath C, the spring S, arranged in the said sheath, substantially as specified. i

3. The combination, with the rotating and `endwise-movable shaft i C, havingarm d', of

the sheath C, having oblique transverseslot b, substantiailyas specified. h y i In testimony that I claim the above I have i DANIEL DOAN.
