(cl. .2o-68) 1 Claim.

weather strip of the character indicated that o will automatically adjust itself to the contour of any threshold over which it may be mounted, and one that will be automatically moved into and out of position relative to the threshold by the closing and opening of thedoor.

It is another object to provide a weather strip of the character indicated that may be quickly and easily applied to a door without removing the door from its mounting in its frame, and without the necessity of performing any work upon the door itself.

It is also an object of the invention to provide a device of the character indicated that will be economical to manufacture, that consists of few and simple parts, that may be readily applied Without the use of skilled labor, and that will be substantial, strong, durable, and highly eiiicient in its practical application.

In the drawing:

Figure 1 is a front elevation of a device em bodying my invention, with the front plate removed, and in position on a door.

Figure 2 is an enlarged sectional view on line 2-2 of Figure 1.

Figure 3 is an enlarged sectional view on line 3-3 of Figure 1.

Figure 4 is an enlarged elevation of a portion of the strip lifting operating rod with associated parts.

Figure 5 is a diagrammatical illustration showing how the strip operates on a worn sill or threshold.

Referring now more particularly to the drawing, I show at I a threshold, at 2 a portion of the door frame, and at 3 a portion of a door hingedly mounted on the frame at 4.

The casing enclosing the operating mechanism in the present instance comprises a strip of sheet metal 5 having a length substantially equal to the width of the door against which it isseated with its lower edge aligning with the bottom of the door and its top edge turned outwardly to form a top flange 6. The front of the casing is similarly formed by a strip 1 having a top inwardly turned ange 8 disposed to seat on flange 6. The two strips are separated by spacers as 9, and the whole is secured together and to the door by screws as I0.

At II is shown a strip of felt equal in length to the casing 5-1 and disposed lengthwise therein. The top edge of the felt strip II is supported and bound by four pieces of sheet metal as I2, I3, I4 and I5, these binding pieces being spaced apart lengthwise as at I6, I1 and I8. The spacing at I6, I1, I8 is such that each part I2, I3, I4, I5 has some freedom of action, yet the strip II as a whole is at all times held in longitudinal alignment.

At the center of each part I2, I3, I4 and I5 is mounted an upstanding loop as I2a, I3a, I4a and I 5a, the several loops extending upwardly the same distance. At I9 is a flat bar passing through the several loops and vertically slidable therein, the width of the bar being less than the height of the loops.

On the center of the bar I9 is mounted an upstanding tab 20, and at 2I is a bell-crank pivotally mounted on casing part 5 as at 22, with its long arm pivotally connected to the tab 20 at 23 and its short arm engaging a pull-rod 24 at 25.

The rod 24 is slidably connected to the bellcrank at one end, and at that end is bent over as at 26 so that a pull on the rod will actuate the bell-crank. The other end of rod 24 slidably engages a stop 21 on case part 5 and is tted with a head 28. A spring 29 is mounted on rod 24 between the head 28 and stop 21, and the extremity of the rod beyond head 28 is threaded to receive a threaded sleeve 30.

In use, the device is assembled and mounted on the door as described, and the sleeve 30 is adjusted on the rod 24 so as to project slightly beyond the end of the casing 5--1. When the door is open the spring 29 operates the rod and the bell-crank 2l to elevate the bar I9 and the felt strip II suspended therefrom. When the door is closed the sleeve 3B contacts the frame 2, thereby compressing the spring 29 and sliding the rod 24 inwardly and releasing the bell-crank so that the strip II will drop by gravity to its seat on the threshold I.

An important feature of this invention is the mounting of the strip II. Since this strip is made of felt, or some similarly flexible material, it readily accommodates itself to a worn threshold as shown in Figure 5 since the several parts I2, I3, I4 and I5 are spaced apart a little and the intervening portions of the felt strip I I function as hinges, permitting. the weight of each part to seat the felt portion which it binds on the underlying portion of the threshold however much it may be worn away.

In the present instance the tab 20 is pivotally mounted at Za a little off center of the bar i9, the end of the strip support adjacent the hinged edge of the door therefore being slightly heavier than the other end. Since the hinged edge of the door approaches the centerline of the threshold in advance of its free edge the result is that as soon as the bell-crank 2l is released slightly the inner end of the felt strip seats upon the threshold, and then the weight of the bar and the other parts is applied to seating the balance of the strip.

Although but one specic embodiment of the invention has been herein illustrated and described, it will be understood that Various alterations in the details of construction and mode of application and assembly may be made Without departing from the scope of the invention as indicated in the following claim. i*

I claim:

A weather strip assembly comprising, supporting mountable upon the bottom of a door to extend the length thereof, a vertically movable and substantially horizontal bar disposed length- Wise thereof intermediate its length, means operative to lift the bar mounted on the supporting means and pivotally connected to the central portion of the bar, a iiexible threshold strip having its top edge reinforced with longitudinally spaced rigid members disposed below said bar, and a vertically slidable lifting connection between the center of each member and the overlying bar.

ALBERT EGLI.
