WEATHER STRIP.

Application led March 2, 1923. Serial No. 622,273.

I To all whom it may cof/wem.'

Be it known t-hat I, FRANK E. AUSTIN, a citizen ofthe United States, residing at Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Weather Strips, of which the following is a specification.

My invention relates to weather strips as applied to swinging doors and it is of that class in which a strip is hinged horizontally to the lower edge of the door, being automatically tilted or ypressed downward to form a close joint with the threshold when the door is closed and tilted upwardly and out of contact with the threshold when the door is open.

My invention is illustrated in the accompanying drawing in which Fig. 1 shows a front elevation of a door to which my weather strip is applied,

Fig. 2 is a front elevation of the lower portion of the door, showing the same partially open with the weather strip raised from the threshold,

Fig. 3 is a section on the line 3-3 of Fig. 1 and,

Fig. 4 is a section on .the line 4-4 of eferring to the drawing, 1 indicates the framework of the door; 2 is the door proper and 3 is the threshold over which the door swings. The weather strip 4 is horizontally hinged by suitable hinges 5 on the` lower end of the outside face of the door and lin position where it can be pressed close against the threshold 3 as shown in Fig?) or lifted moreor 'less completely therefrom as shown in Fig. 4, thus allowing the door to swin back freely.

For t e purpose of forming a close joint with the threshold 3, I secure on the under side of the strip 4, a strip of felt, rubber, or other flexible material 6.

The weather strip `is tilted upward or depressed to its closed position by a bell crank lever 7 pivoted to the face of the door and to an eye or loop 9 secured to the strip by a link 8. The bell crank lever 7 is pivoted to the door by a pivot 10 and connecting the pivot 10 with the loop 9 is a spring 11 by which the strip 4 is kept normally pulled upward in its open position. The lever 7 is operated to close or lift the strip bythe rod 12 pivoted by one end to the lever 7. The opposite end of the rod passes through an eye bolt or other suitable holding device 13 terminating adjacent to the door casing 1. Abutting against the end of the rod 12 and inserted into the body of the casing is an adjusting screw 14 which the weather strip may be more or less tightly closed when the door is in its closed position. The adjusting screw 14 may consist simply of `a square-headed screw screwed into the casing of the door.

It will be readily seen that when the door is closed, the rod 12 will be forcedv lengthwise against the face of the screw 14. The upper end of the angle lever 7 will be thus forced to the left thereby shutting the hinged weather strip closely down over the surface of the threshold as shown in Figs. 1 and 3.

As soon as the door is started to be opened, the strip will be tilted upward by the action of the spring 11.

Such a weather strip is exceedingly simple in its construction, insures a close joint with the threshold and may be readily adjustable to provide against any warping or other variation of the door and its casing.

, I claim The combination of a door, a weather strip hinged to the lower edge of the door,

a bell crank lever pivoted to the surface of the door and connected vwith said weather strip to raise and lower the same, a spring for lifting said stripy from the threshold, connecting the pivot of the bell crank lever with the weather strip.
