METAL THRESHOLD AND WEATHER-STRIP. I

SPECIFICATION forming part of Letters Patent No. 580,801, dated April 13, 1897. Application filed August 15, 1896. Serial No. 602,909. (No model.)

To all whom it may concern.-

Be it known that I, JAMEs T. RAMsDEN, a citizen of the United States, residing at Cherokee, in the county of Cherokee and State of Iowa, have invented a certain new, useful, and valuable Improvement in Metallic Thresholds and YVeather-Strips, of which the following is a full, clear, and exact description.

My invention has relation to metallic thresholds and weather-strips adapted to be applied to doors; and it consists in the novel construction and arrangement of its parts, as hereinafter described.

The object of the invention is to provide a combined metallic threshold and door-strip which when the door is closed will efiectually close the crack between the lower edge of the door and the threshold.

The further object of the invention is to provide such a device that will not interfere with the opening or closing of the door.

The further object of the invention is to provide such a device which is automatic in its operation.

In the accompanying drawings, Figure 1 is a perspective view of the lower part of a door, doorframe, and threshold, showing the Weather-strip attached to the door. Fig. 2 is a transverse sectional view of the lower part of the door and the sill, showing the positions assumed by the parts when the door is partly opened. Fig. 3 is a transverse sectional view of the lower part of the door, showing the position of the parts when the door is closed. Fig. 4 is a perspective view of the lower part of the door with the covering-strip of the weather-strip removed. Fig. 5 is a perspective viewof a shield or hood used at the end of the weather-strip. Fig. 6 is asectional view of the shield or hood.

The door is provided near its lower edge and on its outside with a horizontal plate 1, said plate being secured to the door by any suitable means. The weather-strip consists of the metallic part 2, said part having the major portion of its upper edge 3 curved to the front and having the intermediate flat section 4. At its lower edge the said part is bent under, as at 5. The upper part of the Weather-strip 2 is provided with the elongated perforations 6 6. Said perforations are located in the hollow of the curve formed by the junction of the sections 3 and 4 of the strip. The nails or screws 7 pass through said perforations, and also pass through suitable perforations in the plate 1 and enter the door. The weather-strip 2 is loosely mounted on said nails or screws 7, and thereby the said strip is permitted to have a certain amount of hinge play, as indicated by the different positions of the strip, as shown in Figs. 2 and 3. The elongated perforations 6 prevent any lateral movement of the said strip. At any convenient point the upper edge of the strip 2 is provided with a section 8, which is not in the same plane as the sec tion 3. A fiat spring 9 is secured to the door, and the lower part of said spring comes in contact with the edge of the section 8. Said spring when the door is open is adapted to bring the upper edge of the section 8 as near as possible to the door, and thereby the outer edge 5 of the strip 2 is raised and disengages the threshold, as shown in Fig. 2. The plate 10 is secured to the door above the strip 2. Said plate extends out from the door, and at its lower. edge is provided with an inwardlyextending flange 11. When the door is closed, the section 3 of the strip 2 is adapted to come in contact with the flange 11, as shown in Fig. 3. The spring 9 and the end of the plate 10 is covered by the hood 11, as shown in Fig. 1. The said hood, in addition to protecting the spring and the plate, prevents anything from catching in the end of the plate 10.

The threshold consists of the metallic strip 2, supported from beneath by the block 13. The outer edge of the threshold is inclined downward, as at 14, and when the weatherstrip 2 is in the position as shown in Fig. 3 the section 5 comes down against the downwardly-extending surface 14 of the threshold, thereby making a tight joint and preventing the air or moisture from getting in between the lower edge of the door and the upper surface of the threshold. On the side of the door-frame and a little above the threshold is secured the elongated perforated lug 15. Said lug is secured in place by means of the screw 16. The said lug is adapted to be shifted horizontally and secured in its proper position by tightening the screw 16. When the parts are in the position shown in Fig. 2 and the door is closed, the inner edge of the lug 15 comes in contact with the section 5 of the strip 2 and forces the same down around the outer edge of the threshold, and when the door is shut the said lug 15 will have forced the parts in the position shown in Fig. 3.

When the door is open, the spring 9, bearing against the section 8 of the strip 2, will force the outer end of the strip up, and as the door is opened the said end of the said strip will clear the threshold, and the door can be opened without interference.

When the door is closed, as shown in Fig. 3, it will be seen that the weather-strip is against the lower outer face and edge of the door, and thus there is no space left between the inner face of the strip and the outer face of the door to admit the passage of air behind the strip. It will also be seen that when the door is closed its outer face is in substantially the same perpendicular line as the outer edge of the threshold, and thus a good cover can be made by the weather-strip over the crack between the lower edge of the door and the threshold.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with a door, a threshold having at its outer edge a retreating surface, the outer edge of the threshold being in the same perpendicular line as the outer face of the door when the door is closed, a weatherstrip hinged to the outer face of the door, the inner face of the weather-strip adapted to come in contact with the lower edge of the outer face of the door when the door is closed, said weather-strip having at its lower edge a retreating section, said retreating section of the strip adapted to come in contact with the retreating surface of the threshold when the door is closed and close the crack at the bottom of the door.

2. In combination with a door having a weather-strip hinged thereon, a threshold consisting of a metallic strip having an elevated section, a retreating section formed. in the strip at the outer edge of the threshold, the weather-strip on the door adapted to engage the retreating section of the threshold when the door is closed.
