Application filed October 31, 1921. Serial No. 511,731.

T all whom it may concern- Be it known that I, GEORGE P. RAsoK, a citizen of the United States of America, and resident of Des Moines, Polk County, Iowa, have invented a new and useful Threshold Weather Strip, of which the tollowing is a specification.

An object of this invention is to provide an improved weather-strip adapted to, be attached to the lower marginal portion of a hinged door and to be pressed into close sealing engagementwith the threshold when the door is closed.

A further object of this invention is to provide an improved threshold weatherstrip for hinged doors adapted to engage guides on the door casing and be forced by said guides into sealing engagement with the threshold as the door is closed.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which- Figure 1 is a perspective view showing a portion of a door casing and door equipped with my improvement. Figure 2 is an end elevation of the weather-strip attached to a door, shown in two dilferent positions, the threshold being shown in cross-section.

In the construction and mounting of the device as shown the numerals 10, 11 designate jambs of a door casing, 12 a door hinged to the jamb 11 and adapted to close against stops 13, 14;, and the numeral 15 is a threshold, all of which may be of any suitable type and construction, and are here shown conventionally.

A strip 16, of suitable sheet metal and of a length corresponding substantially to the width of the door, is fixed to the lower portion of the door, as by screws 17 in a hori zontal row, and is mounted on that face of the door which contacts the stops 13, 14:.

as The screws 17 are arranged along the upper margin of the strip 16 and are spaced from the lower margin of the door a suitable'dist ance to permit the action of the strip hereinafter explained. The strip 16 is formed at its lower margin with a reeurved loop 18 extending from end to end thereof, projecting away from the door in substantially a horizontal plane near the lower margin of the door, and having its opening directed toward the door. formed with a rib or angular bead '19 extending from end to end thereof and spaced a short distance below the row of fasteners The strip 16, is also 17, and said rib or head is so formed that i extending from end to end of the recurve loop 18 of the metal strip. The loop 18 may be formed with dents or depressions 21 at intervals to retain the compression strip in place. The head of the T-shaped compression strip 20 lies in a plane just behind the metal strip 16, and is adapted at times to contact with the adjacent face of the door 12 along its lower margin; and said head is also adapted to contact, at its lower margin, with the upper face of the threshold 15, as shown by solid lines in Figure 2, therebyeil'ectually closing and sealing any crack which might otherwise exist between the lower margin of the door and the threshold. Curved guides 22, 23 are fixed to lower end portions of the stops 13, 14 or jarnb members and project outwardly from the faces thereof just above the threshold 15.

The lower faces of the guides 22, 28 are of convex curvature and are so arranged that, in the process of closing the door, they are engaged by the outer edge of therecurved flange or loop 18, and continued closing movement of the door causes said loop, and with it the lower portion of the metallic strip to be pressed toward the adjacent face oi the door. Such movement also exerts a downward pressure on the loop 18 and compression strip 20, and when the door has arrived at its fully closed positionsuch pressure causes the compression strip to T011111 a seal for the joint between the lower n'iargin of the door and upper face of the threshold which excludes all drafts aswell as moisture from without. The guides 22, 23 not only serve to guide the loop and compression strip to their sealing position, but hold them in such position so long as the door is closed, as shown clearly by the solid lines in Figure 2, the metal strip, recurved loop and compression strip. being under tensaid metallic strip being resilient and normally standing atan angle away from the door, saidmetallic stripbeing formed at its lower'margin with a 'recurved loop opening toward the door, a compression strip sub- I, srm'mau T-shaped in cross-section having its leg flange mounted in said loop and its head directed toward the door, and curved guides carried by the door casing and adapted tobeengaged by end portions of said loop whenthe door'is closed, and said guides be ing so curved and thewveatherstrip so posiv tioned on the doo-rthat the head of the cornpression strip is forced against the door and also against the threshold when the door is closed. r

- 2. In a weather-strip, a resilient metallic strip adapted to be secured at onernargin to the outer face of a door transversely of the lowerportion thereof, said metallic strip being formed with a longitudinal bead or rib adjacent its upper margin forming an integral hinge, said metallic strip also being formed with rec-urved loop at its lower marg n opening 'toward the outer face of the door, and a compression strip of flex ble and compressible material, formed substantially. T-shaped in cross-section and haying one flange pro ect1ng and secured with n said recurved loop, the head ofsaid compression strip being adapted to engage at times with theouter face of the door and extend below the edge thereof whereby it also isa dapted to engageathreshold below said door.
