Application filed February 27, 1924. Serial No. 695,563.

My invention relates to improvements in Weatherstrip. One of its objects is to provide an improved all metal Weatherstrip. Another object is to provide an improved Weatherstrip having a more uniform resilient tension over a wide range of adjustments, whereby long period of uniform resiliency in use is insured. Another object is to provide an improved form of metal Weatherstrip whereby improved and continuous close contact is maintained the full length of the joint. Another object is to provide normally for a double sliding or surface contact at the joint. Another object is to provide a Weatherstrip better adapted to exclude wind and water. My invention also comprises certain details of form and combination of components, all of which will be fully set forth in the description of the accompanying drawings, in which;

The accompanying drawings illustrate the preferred embodiments of my invention. -As illustrated in Figs. 1, 3, 4, and 5, the Weatherstrip is constructed of resilient sheet metal and comprises a plane central section-15, at one end of which the metal is bent atian angle to'section 15 to form a section 16,, andlis then folded upon itself to form a section 17. At the opposite edge of the section 15 is a section 18, bent at an angle to section 15, and the metal then folded upon itself to form a section 19. The free edge 20 of section 19 is preferably slightly curved or may be folded upon itself to provide a smooth finished edge adapted to slide freely over the face of the door or window frame.

As illustrated in Fig. 3, the parallel sections 16 and 17 are attached by a series of nails or screws 21 to a window frame 22, and where the joint between the frame 22 and the sash 23 is wide or loose, the weatherstrip occupies substantially the position shown in Fig. 3, with the section 18, pressed resiliently against the face of the sash 23, and the edge 20 of section 19 pressed resiliently against the face of the frame 22,

so as to effectually exclude wind and water. lVhere the joint between the sash 23 and frame 22 is close as shown in Fig. 4, the Weatherstrip assumes substantially the position shown in Fig. 4, in which the section 18 is held resiliently against the face of the sash, the edge 20 of section 19 is held resiliently against the frame, and also the section 15 is bowed so that its curved central portion is held resiliently in contact with the sash. In both positions 3 and 4 the section 17 is also held resiliently against the face of the frame 22 to a greater or less eX- tent depending upon the extent to which the nails 21 permit the sections 16 and 17 to move relative to the frame, under the strain applied by the sash to sections 15 and 18. The Weatherstrip is designed to be held substantially rigidly to the frame 22 at the point where the nails are applied. Leverage is applied by the sash, tending to flex the Weatherstrip from its original outline. at the extreme end of section 18 where such leverage would be most effective, and where the widest range of movement would be capable of taking place. The resilient action of section 19 tends to counteract the action of leverage or force applied to the section 18. which results in the tension required ,to, depress section 18 toward the frame 22 remaining substantially uniform for all positions. and at the same time no one of the yielding portions of the strip is strained to an extent which would tax .its moment of resiliency and cause it to take a permanent bend or hence the stri tends perform its functionsand to retain substantially all of its resiliency for long periods of useful Sel'VlCe.

In the modification Figs. 2, U, 7, and 8 the Fig. 1, is curved instead of plane. A section 31 corresponds to the section 16 of Fig. 1, and a section 32 corresponds to the section 17 of Fig. 1; The section 32 may be in one plane as illustrated in Fig. 1, or itmay be bent to an obtuse angle as shown in Fig. 2, dependingupon the amount of resiliency desired in the Weatherstrip. A section 33 cor responds to the section 18 of Fig. 1, and a seetion lilcorresponds tothe section 19 of Fig. 1. The section B Lis preferably curved or folded upon itself at 35 in order to pro-- vide 'a smooth edge adapted-toreadily slide alongthe face of'the frame 36 in operation. As shown in Fig. 2 the section 34 is bent at an obtuse angle but'may be all in one plane as shown in the section 19 of'Fig. 1.

Fig; 6, illustrates substantially the position of the Weatherstrip when applied'to a loose joint between the window frame 36 and a windowsash 37," and Fig. '7, illustrates sub stantially the position assumed by the strip Fig; 2; when applied to a close joint between the sash and frame; Fig. 8, illustrates a position-ofthe parts intermediate of=the positions shown in Figs. 6 and-7s It will be notedin Figsi6 and 7 that due to the obtuse angle in the section'32 the middle portion of said section does not contact with the face a of the frame, and hence that the section 30 is given thereby increased resiliency Where it jo-ins'the section 31, and hence is better able to apply uniform resistance to pressure from the sash, and to retain its resiliency forlo'ng periods of-service.- The obtuse angle in sec tion-34l tends in like manner to increase the resiliency of the strip; The sections 17 and '19 of Fig. lare adapted to be bcnt'to obtuse angles as shown in the corresponding-sec tions 32 a-nd3 t'0fFig. 2, and for a like purpose.

In'Fig. 5 l have illustrated ;a strip sinlilar to Fig. 1,l)llt with-a section 170 corre spending-to section 17 of Fig, bent. to an obtuse angle, similar to that shown at 32 of Fig. 2, andsaid stri'papplied to the'joint between a door frame 40 and a door 41. In Fig; 9, I have illustrated at 60 the manner in which the Weatherstrip is cut away or recessed opposite the door latch or lock bolt to enablethe latch or bolt to enter its recess in the door frame, and it will-be noted that such recessdoes not entirely sever the strip, and in fact does not materially reduce itsstrenojth.

and waterproof oint, from top to bottom the door irrespective of the latch and bolt or bolts.

Another important advantage of my im- 0 section 30 corresponding to the section-l5 of It will also he notedthat the section 19 still functions to constitute a continuous wind proved strip is that the section ii or 25; rrhere it extends past the edge of the section 16 or iii serves to prevent the united edges of sections 16 and 17 or 31 and 32 from lifting or cocking away from the face of the frame to which they are attached by the nails 21 at points intermediate of said nails and enables the nails to be spaced further apart. T he curve in the sections 15 and 30 prevents buckling or bending ofthe stripsand secures superior contact with the opposite face of the joints.

Thea pparatus herein shown and described is capable of considerable modification within the scope of the claims without departing from the spirit of my invention.
