WEATHER STRIP Filed Oct. '7, 1929 [N PEA/127053.

Patented Jan. 6, 1931 UNITED STATES WILLIAM HEINEN, OF GRASSTON, MINNESOTA WEATHER STRIP Application filed October 7, 1929. Serial No. 397,867.

My invention relates to weather-strips in general and more particularly to a weather strip adapted for use on doors. The main object is to provide a simple, inexpensive and eflicient weather strip of certain novel'construction as hereinafter fully set forth, reference being had to the. accompanying drawing in which,-

Fig. 1 is an inner face View of the lower part of a door with my improved weather strip device attached to its lower ed e in operative position, parts of'the door rame being also shown.

Fig. 2 is an enlarged vertical sectional view as on line 2-2 in Fig. 1, showing additionally a threshold.

Fig. 3 is a fragmentary detail in enlarged scale of my weather strip shown in perspective.

Fig. 4 is a horizontal sectional elevation as on line 44 in Fig. 1 showing a top view of my weather strip in operative position.

Fig. 5 is an end elevation of my weather strip and a certain type of padding material.

Referring to the drawing by reference numerals, 10 designates a door hinged at 11 to the usual door casing member 12 which latter has a counterpart 12A with a door-stop strip 13. 14 is the usual threshold suitably secured to floor 15 between the casing members 12-12A.

It is well known in the building industry that the lower edges of doors for various reasons spread more or less from the adjacent face of the threshold, making an opening 16 which admits cold air, sleet, snow, etc., 1nto the building at the floor level. I am aware that a number of types of weather strips have been invented to stop this passage of air, etc., under doors, but will herein fully set forth the advantages and simplicity of my device which in actual use has proven highly eflicient, its particular advantages being duly stressed.

The main body of my device comprises an elongated strip 1717A of sheet metal, the

length being in eachca'se determined by the width of the door to which it is to be attached, said strip being approximately L-shaped in cross section but its lower flange against the 17A at an obtuse angle with relation to the plane of the upright flan e 17, the free edge of the inclined flange 17% being bent under and inwardly to form a short inwardly directed flange 17 Bnormallly in spaced relation I to and under the flange 17 for the purpose of clamping therebetween the outer edge of a suitable soft pad 18 which is further affixed to the underside of flange 17A by rivets 19 or equivalent means arranged in a row near the upper part of said flange 17A. The upright flange 17 is provided with a suitable number of apertures 20 for screws, nails, or like means 21 to hold the device on the lower part of the door 10. The angle of the flange 17A is such as to correspond with the adjacent angular face 14F of the threshold and so spaced from said face that the padding 18 will fill the space therebetween and consequently of course'prevent assage of air, sleet or snow under the door into a room. The clamping flange 17B engages the upper edge part of the padding, preferably above the corresponding lower edge thereof, so'the said part 17 B is consequently parallel to and slightly above the floor. he main function of the padding is to press against the inner angular face of the threshold only as distinctly shown in Fig. 2, when the door is closed. The said pad 18 may beof felt or othersoft material, but in Fig. 5 I have illustrated a preferred material, namely a strip of animal pelt of which the hide part 21 is clamped at 17 B and secured as at 19 while the fur part 21F extends and is exposed downwardly to bear 35 weather strip. Such strip effectively closes off draft, snow, sleet, etc.

In Figs. 1 and 4,.is distinctly shown that the-end of my strip nearest the hinged edge of the door is cut ofl angularly, makin an angular face 17F and permitting the 001' to be swung wide open as to dotted position (10) in said Fig. 4.

Obviously the pad holding means 19 and 17 B hold it in rigid position at all times and prevent the, pad from rolling under or doubling up when the door is swung. It is prefer-red to have the padding so mounted on the door that it does not touch the floor and accumulate, dust, germs or dirt but 13 offective for its main purpose when the door is closed and it is in the position clearly shown in Fig. 2. If it contacts with the floor, small objects that may be thereon in the path of 4 5 movement of the door would furthermore interfere with the closing of it and proper functioning ofthe strip. The metal part of my device is preferably a heavy galvanized sheet iron and the padding may be either a suitable felt, or the like, or a good quality of sheep skin, the latter being most eflective where the threshold may be uneven or the floor and threshold worn down uneven. A feature is that only the upper metal flange is fixed i to the door while the padding is underneath the lower flange and any moisture which may accumulate will simply run ofi and not contact with the padding, the latter thus not accumulating y moisture, subject to freeziug and consequent inefiective use.

The mounting, preferred construction and use of my improved weather strip have now been fully set forth. It is obvious that its use is not limited to doors but it may also be used on casement-windows.

I claim:

A weather strip for doors, hinged windows and the like constructed to be closed over a threshold having an inclined face inwardly of the inner side of such hinged member and below its lower edge, said weather strip comprising an elongated sheet metal strip of approximately L-shape in cross section, the upper flange thereof adapted to be fixed near the lower edge part of a door or the like and its outer member extending in a plane at an obtuse angle to the upperflange and normally in parallel relation to said face of the threshold, a padding strip L0 fixed to the under side of said latter flange and adapted to close the space between said flange and the adjacent face of the threshold, said means for fixing said padding to the lower metal flange consisting in part in bending the lower free edge of said flange downwardly thence inwardly to form a narrow edge flange-below and parallel to the outer part of the lower flange to clamp the padding material therebetween, and. further means for holding the padding material consisting in providing a row of apertures near the upper part of said lower flange for rivets or like means passed therethrough and through the corresponding upper part of the padding. In testimony whereof I afix my signature.

W'IILIAM P. HEINEN.
