JOHN W. HENRY, OF ORAWFORDSVILLE, INDIANA.

WEATH ER-STRI P.

SPECIFICATION forming part of Letters Patent No. 736,392, dated August 18, 1903. Application led January 2l, 1903. Serial No. 139,975. (No model.) l

To all .whom it may con/cern,.-

Be it known that I, JOHN W. HENRY, a citizen of the United States, residing at Crawfordsville, in the county of Montgomery and `State of Indiana, have invented a new and useful Weather-Strip, of which the following is a specification.

i This invention relates to that class of weather-strips attached'to` thebottoms of doors and operated by the opening and closing of the door for excluding air and moisture, and has for its object the production of a device of this character simple in construction,

easily applied, and which will engage the door. or holding-strip at one point and the carpet strip or sill at another, so that the joints between the parts will be eectually closed. y Another object of the invention is to produce a device of this character which will be maintained normally in an inoperative position `when the` door is open, and thus obviate unnecessaryfriction.

Other novel features of the invention will be disclosed in the annexed specification and be specified in theclaims following.

In the'drawings illustrative of the invention, in which corresponding parts are denoted by like characters of reference, Figure 1 is a perspective view of a portion of a doorframe and doorv with the improvement applied. Fig. 2 is a rear elevation of the device detached, illustrating the manner of constructing and applying the operating-spring. Fig. 3 is an enlarged transverse section with the packing-strip closed, and Fig. 4 is a similar view with the packing-strip open or out i of action.

Attachedby hinges 16 to the member 14 is a packing-strip 17, one edge of the packingt strip having the flexible packing 18, of rubber Fig. 3.

or other similar suitable material, and the other edge, 19, formed concentric to the hinges 16 and movable in constant engagement with the adjacent face ofthe door 10, so that no matter in what position the packing-strip may be placed the inner edge of the strip will engage the door and effectually shut off the passage of air or moisture at that point, while the flexible strip 18 will shut off the passage at the opposite edge. The leaves of the hinges 16 will be 'embedded both in the supportingstrip 14 and the packing-strip 17, so that the packing-strip will be maintained in constant contact with the lower surface of the strip 14.

The packing-strip 17,with its yieldable portion 18,closes against the carpet-strip 13 when operated by the door; but when the door is opened the packing-strip will be maintained in its elevated or inoperative position.

The means for operating the packing-strip is a spring, preferably of the torsional7 variety, as shown at 20 in Figs. 2, 3, and 4, and

`will exert its force to hold the packing-strip in its elevated or inoperative position, as above noted.

Attached to the fram-e member 12 is a stop 2l in position to be engaged by the strip 17 when the door is closed to throw the strip downward with its flexible packing 18 in contact with the carpet-sill, the rear edge 19 at the same time remaining in constant engagement with the door and the upper side thereof in con tact with the strip 14, as above noted. By this simple arrangement no gap will at any time be left between the strip 17 and the strip attached to the door or between the sill or carpet-strip and the packing-strip when the door-is closed, as the concentric edge 19 and the contact of the

strips

14 and 16 shuts od all circulation upon one side and the iiexible packing 18 shuts oif the circulation upon the other side, las will be obvious by reference to This produces a very simple easily applied device which is efficient for Vthe purpose intended and operates automatically by the closing of the door and which may be applied to any door and adjusted to fit inequalities and irregularities of the carpet strip or sill.

The parts may be of any suitable material, either wood or metal, or partially of wood and partially of metal, as may be preferred.

Having thus described my invention, what I claim isl. A Weather-strip consisting of a supporting member having a longitudinal recess contiguous to the door, a packing-strip intermediately hinged to said supporting member and foldable by one edge into said recess with the foldable edge concentric to said hinges and operating in constant engagement with the contiguous face of the door, a spring dis- ,posed to maintain said packing-strip normal-ly in an inoperative position, and a stop adapted to close said packing-strip into operative position when the door is closed.

2. The combination of a door, a supporting member having a longitudinal recess contiguous to the door, a packing-strip intermediately hinged to said supporting member and JOHN WV. HENRY.
