AUTOMATIC WEATHER-STRIP FOR DOORS.

SPECIFICATION forming part of Letters Patent No. 653,606, dated July 10, 1900. Application iilod May 14,1900. Serial No. 16,582. (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. ARMAN- TROUT, a citizen, of the United States, residing at Seymour, in the county of Wayne and State of lowa, have invented a new and useful Automatic Weather-Strip for Doors, of which the following is a specification.

My invention relates to that class of weather-strips that are Xed to the bottoms of doors in such a manner that a movable portion of the strip will be automatically operated as required to engage the threshold when the door is closed, and lifted when the door is opened to swing over the threshold and carpet on a floor inside of the door.

Heretofore movable strips have been connected with parts fixed to the bottom of a door in such a manner that they would simultaneously move longitudinally and also up and down relative to the threshold and the part fixed to the bottom portion of the door.l

My invention consists in a sheet-metal plate adapted to be permanently fixed to the outside face of the bottom portion of a door, a strip of sheet-metal hinged to the lower edge of the fixed plate, and mechanism for operating the hinged strip connected with the iixed plate and the hinged strip, as hereinat' ter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure l is an edge View of the lower portion of a door showing the ends of the metal plate and hinged strip and the operative mechanism mounted between them. Dotted lines indicate the normal position of the hinged strip when the door is open. Fig. 2 is an inside face View of an end portion of the metal plate adapted to be xed to a door and the mechanism attached thereto for operating the hinged strip.

Dotted lines indicate the position of t-he hinged strip relative to the lixed plate when the door is closed.

The letter A designates a single piece of plate metal bent at an angle at its top edge and entire length to overlie a strip of wood B, fixed Ythereto by means of rivets or in any suitable way. The lower edge is inclined inward, and at its central portion, at diierent points along its length, are fixed wooden blocks C-,that correspond in thickness with the strip of wood B and have central bores that coincide with corresponding perforations in the plate A, and through which screws d are passed for detachably fastening the complete device to the bottom portion of a door. A second stri p A2, made of sheet metal and corresponding in length with the strip A, is hinged to the lower edge thereof in any suitable way and in such a manner that it will swing vertically to overlie the liXed plate A when the door is open and to overlie the threshold when the door is closed. A metal rod f is mounted in bearers g, fixed to the wooden strip B and bent laterally at its inner end. A coiled spring h is placed on the rod between the said bearers, and the outer end of the spring is tixed to the rod by means of a collar h' or in any suitable way, so that in its normal condition the spring will retain the end ot' the rod projected beyond the end of the plate A, as shown in Fig. 2.

k is a metal plate or bell-crank lever piv; oted to the plate A and pivotally connected with the inner end of the rod f, and m is a metal strap pivoted to the long arm of the bell-crank at its inner end and hinged to the edge of the strip A2 at its outer end in such a manner that when the door is closed and the projecting end of the rod contacts with the door-jamb the rod will move inward and by means of the bell-crank lever 7o and the hinged strap m will actuate the hinged strip A2 as required to swing it down upon the threshold, as shown in Fig. l, and as required toclose the crevice under the door to prevent dust, cold air, water, or insects from passing in under the door.

Having thus described the construction, application, and operation of my invention, its practical utility will be readily understood by persons familiar with the art to which it pertains, and

What I claim as new, and desire to secure by Letters Patent, is-

l. A weather-strip for doors comprising a metal plate having a strip of wood tixed to its inside face and top edge, wooden blocks fixed to its central portion at different points along its length, a strip of metal hinged to its lower edge to swing vertically and automatic mechanism mounted on the inside face of the metal plate and connected with the hinged plate to IOO operate in the manner set forth for the purposes stated.

2. A Weather-strip for doors consistin g of a metal plate bent inward at its upper edge, a strip of Wood fixed to the inside of its upper edge portion, blocks having central bores coinciding with perforations in the plate fixed to the inside face of the metal plate, a springactnated rod mounted in bearings fixed to the Wooden strip and bent at its inner end, a bellcrank lever pivoted to the inside face of the metal plate and pivotally connected with the spring-actuated rod, a strip of sheet metal hinged to the lower edge of the metal plate and connected with the bell-crank lever by a metal strap pivoted thereto and hinged to the hinged strip of sheet metal, to operate in the manner set forth for the purposes stated.
