WEATHER-STRIP.

SPEC1FICATION- forming part of Letters Patent No. 281,802, dated July 24, 1883.

Application filed January 1l, 1883. (No model.)

Z0 all whom t may concern.-

Be it known that I, JOHN SHOEMAIIER, of Garner, in the county of Hancock and State of Iowa, have invented a new and Improved Teather-Strip, of which the following is a full, clear, and exact description. v

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l shows in perspective my new and improved weatherstrip attached to the bottom' of a door, the parts being in the position they assume when the door is open. Fig. 2 shows the door and weatherstrip in sectional elevation, the parts of the strip being in the positionthey assume when the door is closed; and Fig. 3 is a perspective view, showing the inside of the strip.

The weather-strip is composed of the bar A, the iiap B, hinged thereto, the double-acting spring C, and the strip of rubber D, attached to the edge ofthe i'lap B, which rubber strip may be used or not, as desired. The bar Ais iabbeted, as shown at a, and the ilap B is tongued to correspond, Sas shown at b, so that when the door is closed and the strip B folded down a weather-tight joint will be formed between them. The spring C is fitted in the groove E of the bar A, and in this instance acts upon the torsion principle. Its outer end is bent or rolled, as shown at c, and bears constantly upon the crown f, which is undercut upon its lower side, so that the pressure of the end c of the spring upon its lower side, acting upon an outwardly and upwardly inclined surface, will draw the iap B closed against the threshold of the door. rIhe upper edge ofthe crown f is soformed that when the flap B is turned upward the pressure of the spring C upon it will hold the flap B open or elevated, as shown in Fig. l.

F is a triangular block secured to the doorframe, which serves, when the door is closed, to force the iiap B downward from the position shown in Fig. l a sufficient distance to cause the spring C to act upon the undercut under side of the crown f, which will then draw the'flap B down, bringing its lower edge against the threshold of the door, closing the crack at the bottom of the door, and serving at the same time to draw the lower end of the door closed against the door-j ambs. In opening the door, the lower edge of the iapB will come against the threshold of the door, which will swing it outward a suficient distance to cause the spring C to act upon the upper side of the crown f, and thus serve to hold the flap B up or open until the door is closed again.

Instead of using a single spring, C, for closing the flap B, two or more springs might be used for that purpose, and not depart from the spirit of my invention; and, instead of using torsional springs, direct-acting springs might be used.

. The crown f is faced with sheet metal, as shown at z', Fig. l, to prevent excessive wear of the spring upon the crown.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- The combination, with the block F on the do0r-frame, of the bar A and hinged iiap B, correspondingly rabbeted and tongued at a b, and the torsion-spring C, the latter arranged in a groove of the'bar, bent at c, and resting on the undercut crown f of the flap, as shown and described.

JOHN SHOEMAKER.
