FRANK REESE, OFKMINNEAPOLIS, MINNESOTA, ASSIGNOR TO REESE METAL WATHER STRIP CO., OF MINNEAIOLIS,l MINNESOTA, A. CORPORATION 0F MINNESOTA l THRESHOLD l Y Application filed February 10,-1930. Serial No. 427,355.

My present invention provides a simple and highly efficient threshold and flashing for cooperation with a doorbottom weather strip to form a weather-tight joint between a swinging door and floor or sill and for the disposal of water collected between the threshold and hashing. Y

To the above end, generally stated, the invention consists of the novel devices andy Fig. 3 is a perspective sectional view ofthe i threshold, some parts beingr broken away and sectioned;

Fig. 4 is a perspective view -showing a section of the flashing; and

Fig. 5 is a perspective view showing a section of the backing, as illustrated in Fig. 1.

The threshold, which is formed from a single piece of metal, comprises a flat top member 6 and inner, outer and intermediate supporting flanges 7, 8 and 9, respectively. These flanges 7, 8 and 9 extend the full length of the top member 6, and the inner flange 7 is in the form of a relatively fiat ogee curve the top of which is spaced from the inner edge of the top member to leave the same unobstructed and its bottom edge is substantially directly under said inner edge of said top member.V The outer flange 8 is formed on a flat ogee curve, extends materially outward of the top member 6 and its top is spaced slightly inward from the outer edge of said top member.

The intermediate flange 9 is formed with the flange 8, is located substantially midway between the bottom edges of the anges 7 and 8 and is perpendicular to the plane of the top member 6. The threshold is rigidly secured` tothe Hoor 10 by long screws 11 which extend through holes in the top member 6 between the flanges 7 and Sand their heads ,are countersunk so that they are flush with theupperfface :j

of said top member.`

Formed in the lower edge of the supporting anges 7,;8 and 9 is aplurality of longitudinally spaced-weep holes 12and it is important to note that said holes inthe several supporting'flanges `are staggered so that there will not be a direct draft therethrough. 1

A relatively widethin metaljfiashing 13, in.

the formof a flat plate, nailed or otherwise` rigidly secured to the floor 10 under the threshold and all three supporting fianges 7, 8 and k9 rest directly thereon. The inner edgel portion of the flashing 13 is turned into an upright position'to afford a flange 14, the upper edge portion of which is rolled toward the threshold and downward out ofl contact with the top member 6 and supporting flange 7., l

'Akbackingis provided for the ange 14 and,as. shownin Fig. 1, this backing is inL the form of an angle molding 15 and in Fig. 2 itis substantially in the formof a quarter round molding 16. The upright flange of the molding 15 directly engages the flange 14 and its horizontal flange rests on the floor 10, projects away from the threshold and is secured by screws 17 to said floor.

The molding 15 is designed for use when the floor 10 is covered with a carpet 18 having a lining 19, as shown in Fig. 1, and which carpet and lining extend to the vertical flange of the molding 15 and cover the bottom or horizontal flange thereof. The molding 16 is designed for use on a bare floor or where a rug is used and is secured to the Hoor 10 by screws 20. This molding 16 has a vertical member 21 which directly engages the flange 14 as a backing.

Mounted over the threshold is a horizontal swinging door 22 provided with a bottom flange 14 is spaced from the weather strip 23 to leave clearance therebetween.

In case condensation forms on the inner side of the door 22 the same will run down thereon follow the under side of the weather I strip 23 and drip between the flanges 7 and Y 14 where the saine is collected and will escape over the flashing 13, which projects the underlying floor 10, through the weep holes 12 to the outside of the building. The moldings 15 and 16 in addition to protecting the flange 14 by forming a rigid backing therefore to prevent the saine from being bent or otherwise damaged, gives the threshold a neat and finished appearance.

15 What I claim is:

1. Al threshold having inner and outer sup- 'Y porting flangesthe former of .which at its l[junction with the threshold is laterally spaced Y from the inner edge of thethreshold, the

' outer face of the inner range at the bottom edge thereof is substantially directly under the inner edge of the threshold, and a flashing under the threshold and extending outward of its two flanges, said flashing having at its inner edge a perpendicular flange with which the inner Hange of the threshold engages to position the threshold on the flash- The structure defined in claim 1 which i further includes a removable backing for the flange of the flashing entirely inward there- (fait, and means for securing the backing to a oor.

3. A flat` fiashing resting directly on a floor throughout its entire width and having an upstanding flange at its inner longitudinal edge, and a backing for the lange supported directly on the floor entirely inward of o kthe flange and'secured to the floor, in combination with a threshold supported directly on the flashing. c

In'testirnony whereof I affix my signature. FRANK REESE.
