WEATHER-STRIP.

Application filed. October 23, 1918. Serial No. 259,387. a

To all whom may concern: 1 V 7 Be it known that I, OSCAR SEARS BRAN- HAM, a citizen of the United States, and a resident of Roswell, in-the county of Chaves and State of New Mexico, have invented certain new and useful Improvements in Weather-Strips, of which the following is a specification.

My invention is an improvement in weather strips, and has for its object to provide a strip of the character specified, mounted to move laterally and longitudinally of a door, and controlled by the opening and closing of the door for movement in such lateral and longitudinal directions, to tightly seal the space between the bottom of the door and the sill when the door is closed.

In the drawings:

Figure 1 is a front view of the lower portion of a door looking from the outside, with the door partly open;

Fig. 2 is a similar View, with the door tightly closed;

Figs. 3 and 4 are sections on the lines 33 and 44, respectively, of Fig. 2, each View looking in the direction of the arrows adj acent to the line;

Fig. 5 is a perspective view of the weather strip with the parts detached, showing a modified form of spring.

T he present embodiment of the invention is shown in connection with a door 1 of usual construction, said door being mounted in the usual frame or casement 2 which has the usual sill 3 at the bottom of-the door, and it will be noticed that the bottom of the door is spaced above the sill slightly to provide for a free opening and closing movement of the door.

The improved weather strip comprises a plate 4 having its upper edge flanged, as indicated at 5, for a purpose to be described, the flange overlying the adjacent face of the body of the strip in'spaced relation, as shown more particularly in Figs. 3, 4 and 5, and this strip is secured to the outer face of the door by means of screws 6 which are passed through vertical slots 7 in the strip and into engagement with the material of the door.

A second strip 8 carries at its lower edge a flexible strip 9 of strip 9 having one edge received within a groove 10 extending longitudinally of the strip 3 en the inner face thereof, the said rubber or the like, the said groove being formed by folding back'the edge of the strip on the body in close rela tion, and then bending the extremity of the edge in spaced relation in the opposite di-- rection. The upper edge of this strip 9 is bent laterally, as indicated at 11, to lie at an obtuse angle with respect to the body, and at approximately the same angle as theflange 5 of the strip 4, and this bent portion 11 moves beneaththe flange 5.

The strip 8 has are shaped slots 12 near its ends which are engaged by threaded stems 13 extending laterally from the strip 4. Leaf springs 15 are arranged between the stems and the strip 8, the said springs being secured to the strip 8 at the top of the groove 10 at one end and bearing at the other against the threaded stem 13, as shown in Figs. 2 and 4, and these springs act normally to move the strip 8 upwardly and toward the hinged side of the door. In Fig. 5 the springs 15 are replaced by coil springs 14, which are connected at one end to the top of the groove 10 and have eyes at the other for engaging the stems 13.

strip 4 a distance corresponding to the length of the'slots 12. and these slots, being cam shaped or eccentric, tend to move. the strip downwardly when it is moved in one direction longitudinally and upwardly when it is moved in the opposite direction. By

means of the screws'6 engaging the slots 7 the position of the strip 4 may be varied inner face of the adjacent side member of the'casement. This engagement between the end of the strip 8 and the cam plate will 100 move the strip 8 longitudinally of the strip 4, and because of the engagement of the stems 13 with the slots 12 the strip 8 will be moved downwardly as well as laterally of the door, into position of Fig. 4, where the 105 bottom edge ofv the flexible strip 9 will engage the sill. So long as the door remains closed, the parts will occupy the position of Figs. 2 and 4 and the space beneath the door will be tihtl** sealed. As soon however as 110 p a: J 9 7 The strip 9 is slidable with respect to the I the door is partially opened, the Weather strip may spring into the position of Figs. 1 and 3, Where it Will clear the floor.

I claim: v A Weather strip comprising a strip of metal adapted to be secured transversely of the lower end of a door, and having vertical slots: for receivingia securing means,- said strip having its upper" edge turned-back= Wardly upon itself to form an inclined flangeya second-strip mounted to Slide longi-; tudinallyioft he first strip; said second strip having arcuateslots-nearits ends, and-have ing its :upper edge: inclined for engagement beneathsaid flange;- in conforming relationtheretoiand the *first strip having stems enzgagingthe-a-rcuate slots to constrain the sec-- ondistripto'move[laterally when it is moved longitudinal-1y of the first strip disks disposed against the outer face of the second named strip and covering the arcuate slots therein and-"held in place "by nuts threaded on said stems, springs arranged between the strips and acting normally to move the second strip in a direction away from the bottom of the door, said second strip having one end normally extending beyond the adjacent end of the other strip and adapted to'engage the door casing -to-=-;-:move \said fsecond strip
