JAMES T. BLISS AND JOSEPH D. DAVENPORT, OE NORTH PROVIDENCE,

RHODE ISLAND.

Letters Patent No. 98,548, dated January 4, 1870.

IMPRovED WEATHER-STRIP.

The Schedule referred to in these Letters .Patent and making part of the sama To all whom it may concern Be it known that we, JAMES T. BLISS and JOSEPH D. DAVENPORT, both of North Providence, in the county of Providence, and State of Rhode Island, have invented a new and useful Door-Attachment for a substitute for thresholds; and we do herebydeclare that the following specification, taken in connection with the drawings, making a part of the same, is a full, clear, and exact description thereof.

Figures 1 and 2 are sectional views of so much of a l door and the jamb as will, show the attachment, the

door in tig. l being represented as ajar, and in fig. 2 as closed.

Figure 3 is a front view of' the door and the attachment.

The only function which thresholds to interior door-v l carpet.

` A carpet, if the door isintended to be used, cannot be laid over the common raised threshold, as it is often desirable to do in order to improve the effect ot' two connecting rooms, which are covered with a carpet ot" the same pattern, and architects have long desired to devise some means which would dispense with the tlires'hoid,andyetprevent a draught-space nnderfthe door.

Our invention accomplishes this enchand consists in the attachment of a hinged plate to the bottoni; rail of the door, which, by the action of a spring, is lmade to lie a't. against the edge of the bottom rail when the door is open, but will be turned down so as to close the space between the bottom rail and the floor when .the door is closed.

Although the idea is borrowed from the well-known spring weather-strips used upon outside doors, and

operates in a somewhat similar' way, it is nevertheless' to be distinguished from that device iu its arrangement and adaptation to the purpose intended.

lIn the drawings- A s the door;

B, the door-jamb; and

C, the floor, which may be carpeted or not, but if intended to he carpeted, allowance in hanging the door should properly be made therefor.

As seen in the different figures, the door' is hung so as to clear the carpet or ioor entirely when swinging. A plate of thin metal, or other suitable material, D, is hinged, at a, to the' edge of the bottom rail, and it is preferred, for appearance, to make a rebate in such hinge.

Upon the edge ofeachstile of. the door an opening is cut, which should be closed by a neatly-ittingplate capable of removal, if necessary.

At each extremity of the iiap D, and at right angles therewith, or nearly so, are arms E, against which -a spring, I1, is made to bear. Both spring and arms are concealed by the covering plate above mentioned.

In each Aangle of the common rebate inthe doorframe, an inverted inclined plane, G, is set. l Thel eiect is apparent. Upon closing the door-,the front edge ofthe tlap D will strike the planes G, and," in consequence, such yplate will be turned down, and close the space between the bottom of the rail and the carpet, and much more ei'ectnally exclude cold l currents of air than the ordinary threshold would do.

Upon opening the door, the action of the springs F will fold the tlap D against the bottom o the rail.

XVe do not claim, broadly, a hinged flap, in combination with a door and a stop or inclined plane upon the jamb, to close the crack between the door and the threshold; l neither do we broadly claim the use of the spring F, arranged to operate directly upon the hinged plated) but Vt'e claim, and `desire to secure by Letters Patent-` The substitute for thresholds herein described, consisting ot' the combination of the horizontal hinged plate D with the arms E E, controlled by the spring F, and operated by the plane G, construct-ed, arranged, and operating substantially as described.
