WEATHER-STRIP.

' To all whom it may concern:

. Be it known that I, JEAN B. A. LA JEUN- ESSE, of Alameda, California, have invented certain new and useful Improvements in Weather-Strips, whereof the following is a specification.

This invention relates particularly to a weather strip especially designed for use in connection with doors for the exclusion of wind, rain and the like, from between a door and its threshold, and it may also be used in connection with window shutters and other closures.

One of the objects of this invention is to provide a vertical movable weather strip housed within a recess running along the bottom of a door, said'weather strip being automatically elevated when the door is opened to allow a free swing of the latter.

Another and more specific object of the invention is to provide in' a weather strip of this nature operating means which will raise and lower the strip without moving it longitudinally.

The invention also aims to'generally improve weather'strips to render them more useful, practical and commercially desirable.

With these and other objects in view as will become apparent as the description pr oceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter fully described, illustrated and claimed at the end hereof.

In the drawings Figure 1 is a. fragmentary vertical sectional view-through a door showing my improved weather strip mounted thereon and in elevated position.

Fig. 2 is a view similar to Fig. 1, with the weather strip lowered in contact with the threshold of the door.

Fig; 3 is a vertical sectional view.

Fig. 4 is a section on the plane 'of line 44 of Fig. 3, and i Fig. 5 is a section similar to Fig. 4, showing the door partially opened.

Referring in detail to the drawings by numeral, 1 designates a door having a longitudinal channel or recess 2 formed 'in the lower edge thereof, which recess is prefer- Spccification of Letters Patent. Patented J ne 1 192() A Application filed July 13, 1918. Serial 110,244,719. I

ably covered along its top and outer side by the metallic lining 3.

The door swings over the threshold 4 and when closed abuts against the jamb 5 which isformed with the recess 6 shown in Figs. 4 and 5 for a purposeto be hereinafter explained. i I

Within the recess or channel 2 is'mounted a weather strip 7 in the form of a rectanguthreshold 4 to close the crack at the bottom ofthe door, and when the door is opened the. plate is elevated above the threshold so as not to interfere with the swing of the door. The means which I have provided for thus raising and lowering the plate 7 include a lift or rockerarni13 pivotally secured at one end to the stud 10 and extending longitudinally of the plate toward its other end. This arm is slotted as indicated at 14 to permit passage of the stud 9 and is pivotally connected at its inner end to a'link 15 by means of a pivot or stud 16, which passes through the link and arm and is attached to the weather strip 7 Another link 17 is pivotally secured to the pivot 'or stud 18 carried by the outer wall of the channel 2 and is pivotally connected at one terminal tothe corresponding terminal of the link 15 by a pivot or stud 19-forming with said link 15 a toggle joint. Arod 20 is mounted within the door adjacent its free edge and extends from the channel 2 upwardly to an edge openingchamber 21. A crank arm 22 is carried by the lower end of the rod 20 within the channel 2' and is pivotally connected to one end of a connecting rod 23 which is connected to the tog-' gle by the stud 19, thereof. An expansive helical spring 24 encircles the connecting rod 28, bears at one end against a washer 25, and

ward'ly against the threshold 4:.

at its other end against an angular flange 26 formed on an arm 27 which is pivoted at one end to the stud 9. The flange 26 is apertured to accommodate the connecting rod 23.

Anjarm or extension 28 is provided at the upper end of the rod 20 and pro ectS outwardly from the chamber 21 su' iclently far to strike against the end wall '29 of the recess 6, shown in Figs. 4: and 5, when the door is closed. When the door is opened the extension 28 is freed from engagement With'the wall oi? the recess 6 and thesprrn'g' 24 can then expand to draw the rod 1n-v wardly and throw the toggle members 17 and 15 into position shown in Fig. 1. This movement of the toggle 'throws the stud 1'6 upwardly and the stud beingattached to the plate 7 raises thelatter from lowered position into inoperative position "as shown Fig. 1. Now, when the 'dooris swung shut, the extension 28 strikes against the inner end wall of the recess '6,*causing the rod 20' to rotate and move the connecting rod 23 longitudinally and bring the toggle members 17 and 15 into alinement as shown in Fig. 2, which movement lowers the stud.

7 will "bea-p'parent that I'have provided a very practical and efficient weather strip for doors, windows, and other closures, which is automatically moved into inoperatlve position when necessary; I

Having thus described my invention, and an embodiment "of it, in the 'ful-l,1clear and exact terms required bylaw, and knowing that it comprises novel, useful-and valuable improvements in the art to which it pertains, I here state that I do not wish to he limited to the precise construction and arrangement of the several parts, as herein set forth,

as the same may be variously modified by a skilled mechanic without departing from the spirit'of the invention.

What I claim 7 and desire to secure by Letters Patent 'of the United States, is the 01- lowingto wit 7 1. In combination with'a door and the jamb thereof, said door :providechwith a channel at its lower-edge, a weather strip mounted for"vertical movement in said chan- *nel, mechanism including a toggle jioint i for normally holding the weather strip'in elevated position located in said channel, a vertical rod connected to said toggle at one end by a longitudinal rod and having at its opposite end an arm engaging said jamb and thereby operating said toggle.

2. In combinationwith a door, a weather strip mounted for vertical movement thereon, means for operating said strip consisting oi? an arm pivotally connected at one end to the door and loosely connected at its other end to the weather strip, a toggle pivoted to said door and engaging said arm for raising and lowering said arm when the door is open or closed and means 'foroper- 'ating said toggle. I i

3. In combination with a door, a weather strip mounted for vertical movement thereon, an arm pivoted to said do'or 'and to' the weather strip, said arm extending longitudinally 0f the weather :strip and" being adapted when swung to move the weather strip vertically, mechanism' including .a

toggle joint for swinging the arm upwardly when the door is opened and means for spreading said toggle joint to lower the arm and weather strip when the door is closed. R

4. In combination with a door, a weather strip extending transversely thereof and formed with a plurality ofver'tical slots, studs mounted on the door and extending through said slots to slidably secure the weather strip in position, an arm exitending longitudinally of the weather strip and adapted to swing in asubstantia'lly vertical plane, means connecting 'the' swinging end of said arm to the weather strip, a toggle joint connected *to the door and to said arm, means for breaking said toggle .to elevate the arm when the door is open and means for straightening said toggle "when the door is closed and lowering said arm.

5. In combination with a door, aweath'er strip mounted for vertical movement thereon, an arm mounted to swing in a substantially vertical plane, the swingingendof said arm being connected to the Weather strip, a toggle joint connected atone end to the door and at its other end to' said arm, a longitudinally movable rod for collapsing and spreading said toggle ioin'tyand means dependent for action on the position 'o fsaid door for 'movable'rodi 6. In combination with a -door"havinga channel formedj in' the lower edge thereof,

:a weather strip mounted in said channel, a

'shitfti ng said longitudinally toggle joint connected tosaid strip and to the door, a longitudinal'movable rod'connected to the toggle, means 'form'oving said longitudinal movable rod in onedirection for expanding the toggle joint when the door is closed consisting of "a vertical rod located within said door having at one end In testimony that I claim the foregoing a crank arm and at its opposite end an arm I have hereto set my hand this 29th day of engaging a recess in the jamb of the door June, 1918, in the presence of Witnesses. and spring means for moving the longitudi- JEAN B.
