WEATHER -STRIP.

SPECIFICATION forming part of Letters Patent No. 344,773, dated June 29, 1886.

Application filed April 19, 1886.

To all whom it rmty concern.-

Be it known that I, J OHN S. DUFFEE, a citizen of the United States, residing at Rich mood, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in feather-Strips; and. I do hereby declare that the following is a' full, clear, and exact description of the same, reference being had to the annexed drawings,-1naking a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a front elevation of my invention, partlyin section; Fig. 2, a' cross-section taken on line a :0 of Fig. 1, and Fig. 3 a detail perspective view of one of the plates connected to the end of the bracket to which the operating parts of the weatherstrip are connected.

The presept invention has for its object to provide a simple and easily-operating weatherstrip that will effectually and accurately close the space between the shut door and the threshold; and it consists in the details of construction, substantially as shown in the drawings and hereinafter described and claimed.

In the accompanying drawings, A represents the door, and B the threshold, the door having connected to its lower edge a bracket, C, extending the entire width thereof. Vithin the bracket Gis supported a metal plate, D, of a length equal to that of the bracket, and having secured thereto a rubber or felt strip, a, to form a tight and closed joint between it and the threshold.

The plate D iseonnected to eccentrics E by means of links I), said eccentrics being pivoted to the bracket 0, and also to a plunger-bar, F. The distance of stroke of the bar F is regulated by an adjusting or gage device, G, which engages with a screw-threaded shank, c, on the end of the bar. The gage Gr terminates at its outer end in a short rod, d, which passes through an opening in a plate, 6, secured to the inner end of the bracket 0, a similaaplate, 5 f, being attached to the opposite end thereof. By means of the gage G the distance which Serial No. 199,444. No model.)

the rod (1 projects beyond the end of the bracket is regulated, and consequently when the rod is brought in contact with the frame of the door the throw of the bar F and also the eccentrics E is acted upon with greater or less force to bring the rubber strip in contact with the threshold.

\Vhen the door is opened, the strip a is raised flush with the lower edge of theloracket G by means of a spiral spring, H, inclosed in a casing, I, open at both ends. The tension of the spring H is regulated by an adj Listingscrew, h, having a disk, It, on its inner end, which bears on the end of the spring to com press the coils to any degree required. The opposite end of the spring H is provided with a bearing-disk, t, for the end of the bar F to come in contact with, and both the rod d and screw h have slotted heads for engaging therewith a screw-driver for turning them.

The spring H, as will be understood, forces the bar F back to its normal position when pressure is removed from the rod d, and through its connection with the rubber strip a the latter is elevated.

Having now fully described my invention,

what I claim as new, and desire to secure by Letters Patent, isg The plunger-bar F, having a scrcwthreaded shank, 0, an adjusting or gage device, G, en gaging therewith,and terminating in a rod, d, for turning it, in combination with the spring H, contained Within the casing I, and adjusting screw h, for regulating the tension of the spring, the plate D, having the strip a and connected to the plunger-bar by links I), and pivoted eccentrics E, arranged to operatesubstantially as and for the purpose set forth.

In testimonythat I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JOHN S. DUFFEE.
