Application September 8, 1934, Serial No. 743,249 2 Claims. (Cl. 207-68) This invention relates to improvements in means for closing apertures between swinging closure members and for frames, and pertains particularly to an improved weather strip or stop for use upon doors. I

The` primary objecto-f the present invention is to provide a novel form of weather strip or stop wherein a novel means is provided for shifting the stop in a vertical path so that the entire stop is at alltimes within the area outlined by the surfaces of the closure upon which it is mounted.

A further object of the invention is to provide an improved weather strip which is so designed that it may be readily applied to either side of a closure member ormay be adjusted for use in accordance with the side oi' the closure member upon which the supporting hinges are placed.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not coniined to any strict conformity with the showing of the drawing but may be changed or modied so long as such changes or modications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:

Figure 1 is a View in elevation of the lower part of a closure membershowing the weather strip or stop embodying the present invention applied thereto, the casing for the stop being in longitudinal section.

Figure 2 is a sectional view taken substantially upon the line 2 2 of Figure 1.

Frigure 3 is a sectional View taken on the line 3-3 of Figure 1.

Figure 4 is a horizontal sectional view taken through the rear part of the closure and frame showing the closure in closed position.

Figure 5 is a view in perspective of the lower part of the closure and frame showing the shiftable weather strip or stop in elevation.

Figure 6 is a fragmentary view of the central' portion of the device showing the position of the stop shifting means when the stop is down.

Referring to the drawing, the numeral I indicates the lower portion of a door, the side of the frame therefor to which the door is hingedly attached, being indicated by the numeral 2 and a lower hinge being indicated by the numeral 3.

In carrying out the present invention, one face of the door I is cut out or recessed, as indicated at 4, to receive the housing 5 for the present invention. The housing 5 is in the form of an elongated shell of substantially U-shaped cross section, having the inner and outer side walls 6 and l, respectively, and the connecting top wall 8. At each end of the housing, the outer wall 'I has a 5 portion of each end turned at right angles to form an end wall 9 which is in abutting relation with the opposite side wall 6, as illustrated in Figure 5. Extending laterally from the lower edge of the inner wall 5 away from the housing 5, is a bottom 10 flange or plate Ill, which positions against and is secured to the bottom surface of the door I. Suitable securing means may be passed through this bottom flange into the bottom of the door to maintain the housing in position in conjunction with l5 screws II passed transversely through the walls S and of the housing and into the vertical face of the recess 4 in which the housing is located.

The lower side of the housing 5 is open throughout its length and disposed within and extending 20 throughout the interior length of the housing is an elongated shiftable body I2 which also is of U-shaped cross section, as shown vin Figure 3, the lower edge of this body being open and having projecting therefrom the compressible strip of 25 material I3 which is preferably felt or a suitable similar material.

As shown in Figure 1, the body I2 which conistitutes the carrier for the contact material I3 is of a length substantially equal to the interior 30 length of the housing 5 and is Vtransversely rounded slightly at each end, as indicated at I4, to prevent binding as it moves vertically in the housing 5 in the event that the underlying surface with which it comes in contact is not parallel 35 with the bottom edge of the housing.

The felt strip carrier body l2 is supported at each end by a coil spring I5 which is suspended from a pin I6 disposed transversely of the housing 5 between the side walls thereof. At its 40 transverse center, the body 'I has the top wall cut away to form a recess Il and projecting through this recess and beyond the top edge of the body I2 is a roller I8 which is pivotally mounted upon a transverse pivot pin I9 carried by the body I2. 45,

Each end wall 9 of the housing 5 has an yaperture 2! therein adjacent the top wall 8, and one of these apertures has extending therethrough one end of the reciprocable bar 2 I. The inner end of the bar 2`I is pivotally attached, as at 22, 50 to the end of one side leg of an elongated substantially U-shaped camming member 23 which is disposed horizontally within the housing 5 and has the free end of its other leg pivotally supported upon the transverse pivot pin 24 which 55 extends across the housing between the side walls at one side of the transverse Vcenter of the housing. The member 23 is disposed, as shown, with one leg lying above the other and the upper leg, to which the rod 2I is attached, is slightly longer than the lower leg which is fixed to the housing and the said lower leg adjacent the yoke end of the member contacts with the roller I8. It will thus be seen that with the application of longitudinal movement to the rod 2 I, the member 23 will rock downwardly on the pivot pin 24 and force the body I2 downwardly. As illustrated, the outer edge of the lower leg of the` U-shaped member 23 is convex and merges with the rounded or convex outer edge of the yoke portion which connects the legs together so that when the camming member is rocked, these rounded edges will be caused to move smoothly on the roller I8.

As shown in Figure l, an aperture 25 is formed in the side walls of the housing 5 at the opposite side of the transverse center of the housing from the pin 24, and this pin is adapted to be removed and inserted into the apertures 25 so that the rod 2I and camming element 23 may be reversed in their positions so that the rod will extend through the other end wall aperture 20 and the device as a whole adapted to a door having the hinges upon the opposite side from the door here illustrated.

The face'of the door frame 2 against which the rear edge of the door abuts, has a large flat headed screw 26 xed therein to form an abutment for the projecting end of the rod 2 I.

From the foregoing, it will be readily apparent that in operation, when the door I is closed, the free end of the rod 2| will abut the face of the screw 26 and cause the felt carrier I2 to be forced downwardly in a horizontal plane against the tension of the springs I5, so as to bring the felt I3 into contact with the underlying floor or other surface.

. Should the underlying surface be out of parallel relation with the lower edge of the door or the housing 5, the springs I5 will yield to permit one end of the felt carrier to move downwardly in advance of the other so that contact will be made between the felt and the underlying surface throughout the length of the door bottom.

What is claimed isz- 1. A device of the character described designed for insertion in a recess in an edge of a closure, an elong-ated body designed to position in said recess and consisting of a rigid portion and a yieldable portion, said yieldable portion being directed outwardly from the recess, a pair of spring members attached to the rigid portion of the body at the ends and constituting means for supporting the body Within the recess, a roller bearing carried by the rigid portion of the body midway of its ends, a substantially U-shaped element having the outer side of one leg bowed outwardly to form a cam surface which contacts said roller bearing, means pivotally securing the free end of that side of the U-element which contacts the roller and maintaining the element in the recess with the legs of the element lying one over the other above and in the vertical plane of said body, and a reciprocably mounted bar pivotally attached at one end to the free end of the opposite side of the U-shaped element, said bar having its other end normally extended from an end of the recess for Contact with a frame into which the closure may be moved.

2. A device of the character described designed for insertion into a recess in an edge of a closure comprising an elongated body adapted to position in said recess and consisting of a rigid portion and a yieldable portion, said yieldable portion being directed outwardly from the recess, spring elements attached to the rigid portion oI' the body at the ends and operating to support and normally tending to retract the body in the recess, a bearing carried by the rigid portion of the body midway of its ends, an elongated flat element disposed above the body to extend longitudinally with respect to the same and having a substantially U-shaped edge contour constituting a camming surface which has contact with said bearing, means pivotally engaging the flat element at one end of the camming edge to support the element over the said rigid body, a bar mounted for longitudinal reciprocation over and in a path parallel with the rigid body, and a pivotal connection between an end of said bar and the flat element adjacent the other end of the U-shaped camming edge thereof, the other end of said bar being normally extended from an end of the recess for contact with a frame into which the closure may be moved.
