Patent ed Jan. 7, 1930 UNITEDFSTATES PATENT OFFICE MAURICE E. BOSLEY, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE I). W. BOSLEY COM- PANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS WEATHER STRIPPING Application filed August 20, 1927. Serial No. 214,370.

. This invention relates in general to Weatherstripping and has particular reference to an improved weather-tight gasket adapted for use in connection with movable closures for sealing the crevices between the closure members when in closed position.

My invention contemplates the provision. of, an improved Weatherstrip of the type comprising a soft flexible core encased in a sleeve, the edges of which are extended at a side and foldedand seamed together to provide an attaching flange. Such weatherstrips when arranged between closure members that compress the packing require little strength in the flange, but where the closure is against the Weatherstrip without a companionmember back of it, as when the pressure comes in the plane of the attaching flange, tendency is provided for the strip to give back between the points of fastening of the flange and in this event to result in an uneven pressure at these points and the spaces therebetween.

The principal object of the invention is the provision of a Weatherstrip having a strengthening member disposed longitudinally therein for the purpose of maintaining a tight engagement, throughout the length of the Weatherstrip, between the weatherstrip body and a closure member enga 'ng the body in a direction parallel with the p ane of the attaching flange.

A further important object of the invention is the provision of a Weatherstrip having a strengthening longitudinal insert disposed in the flange thereof adjacent the body portion for the purpose of strengthening and supporting the body in operative position.

Another important object of the invention is the provision of a Weatherstrip adapted to conform with, and to maintain close engagement upon, uneven or discontinuous surfaces. When weatherstripping is secured upon a closure member having warped or otherwise discontinuous surfaces, or when the Weatherstrip is positioned upon a corner of a closure member, there is a tendency for the Weatherstrip portions to draw away from close engagement upon the closure member and difliculty is frequently experienced in arranging the Weatherstrip to maintain its engaged position upon the member at points immediately adjacent the apex of the corner,

the resilience of the Weatherstrip causing a continuous curvature rather than a sharp bend conforming with the. angle of the clo sure corner.

Another important object of the invention is the provision of a Weatherstrip having an attaching flange in which there is en: closed a flexible stiffening member adapted to be bent into conformity with the contour of the closure member upon which the Weatherstrip is secured and to maintain a close engagement of the Weatherstrip upon uneven surfaces.

Another important object of the invention is the provision of a Weatherstrip especially adapted for close engagement upon the angular portions of a closure member.

Another important object of the invention is the provision of a Weatherstrip having a bendable insert enclosed within the attaching flange in order to maintain the flange properly in arranged position upon a closure member without using a large number of nails or similar fastening devices.

Numerous other objects of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawirgs, discloses a preferred embodiment there- 0 Referring to the drawings:

Figure 1 is a perspective view of a weatherstrip embodying my invention, portions of which are shown in cross-section;

Fig. 2 is a plan view illustrating the Weatherstrip assembled upon a closure memher, the parts being arranged to show the Weatherstrip compressed by forces acting parallel with the plane of the attaching flange, and

Fig. 3 is a cross-section taken substantially on the line 33 of Fig. 2.

To illustrate my invention I have shown on the drawing a Weatherstrip comprising a core or rope 11 formed of suitable resilient packing material and an enclosing sleeve 12, the mid-portion 13 of which is wrapped about and encloses the resilient core 11 to form a substantially cylindrical Weatherstrip body, and the edges 14 and 15 of which comprise flanges which extend laterally from the cylindrical body portion of the Weatherstrip. These flanges 14 and 15 engage at their junction with the body portion and extend adjacently outward. The extreme edge portion 17 of the upper flange 15 extends outwardly beyond and overlaps the outer edge .of the lower flange 14, and is folded back along a line of bend 16 and engages the lower surface of the flange 14 to provide an integral, outwardly extending, three-ply attaching flange 18, the fly edge 19 of the portion 17 having final engagement upon the body of the Weatherstrip adjacent the base of the flange 18. An insert 21 comprising a strand, roll, or rod of suitable flexible material, is enclosed within the body of the flange 18 and adjacent the body portion of the Weatherstrip, being inserted and positioned between the flange portions 14 and 15. The inter-folded portions 14, 15 and 17 are secured together on each side of the insert by means of a seam 22 formed at the base of the flange between the insert and the body portion, and a seam 23 formed in the body of the flange. These seams secure the insert in position in the flange, the seam 21 also performing the function of securing the mid-portion 18 of the sleeve about the resilient core 11 of the Weatherstrip. The interfolded flange portions may also be secured together bymeans of a seam 24 formed in the flange adjacent its outer edge.

The Weatherstrip is especially adapted for assembly upon a door frame 25, as shown in Figs. 2 and 3 of the drawing, in a position in which a door member 27 closes against the body of the Weatherstrip in a direction parallel with the plane of the flange 18. The Weatherstrip is secured in position by means of nails or similar fastening devices 27, which pass through the flange at spaced intervals and take into the closure member 25. It will be apparent that the portions of the weatherstrip body opposite the fastening members 27 will be supported firmly by the flange and will have a firm engagement with the closure I member 26, whereas in the absence of the strengthening member 21, the Weatherstrip bodyintermediate the members 27 will not firmly engage the closure member because the flange parts. which back the resilient body portion, will sag somewhat between the fastening devices. By providing the longitudinal strengthening member 21, the intermediate portions of the flange are held firmly in position against sagging and the weatherstrip body is backed up so that a uniform engagement between strip and closure member is provided.

The insert not only serves the purpose of stiffening the Weatherstrip body intermediate the fastening members, but also provides means for maintaining the Weatherstrip flange in any position in which it may be ar ranged. This construction provides a weatherstrip which may be arranged in close engagement upon uneven surfaces and one, which, having been disposed in a definite position, will maintain such position against the tension of the natural resilience of the weatherstrip which, after distortion, tends to reassume a normally straight position and to draw away from depressions or other irregularities of the surface upon which the Weatherstrip is positioned. Since the strengthening member is adapted to maintain the flange properly in a definite engaged position, fewer fastening devices are needed to secure the Weatherstrip in place. Not only is economy of fastening devices thus effected, but since the fastening flange is weakened wherever a fastening device passes through, a Weatherstrip which requires fewer fastening devices to maintain it in position is inherently a more durable and satisfactory article.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that many changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
