4 claims. (o1. en -69) trial installations. Similarly, it is applicable to door constructions on ships vand small pleasure boats, such as motor driven cruisers. In addition to being applicable to storm doors both on land and at sea, it may also be applied to screen doors, combination stormv or screen doors-and window constructions and the like. For purposes of illustration, however, this invention will here be shown and described solely in terms of its relation to combination storm and screen doors which are made of` extruded aluminum.

The principal object of this invention is the provision of weatherstripping for storm doors, screen doors, windows and the like, which is exceedingly simple in construction, which may very readily be installed and equally as readily removed and replaced, and which, when installed, affordsl a tight seal against the elements, including rain, snow, wind and the like. Itis also proof against the entrance of mosquitoes, flies and other insects.

The Weatherstripping herein described and claimed comprises but two component parts: a` rubber strip and a metal holder for said strip. The metal holder is made, preferably, of a single strip of extruded or bent aluminum. It is pro'- vided with what may be described as a pocket for the rubber strip and said rubber strip may be inserted into the pocket preparatory to joining said strip to said holder. The pocket may then be closed .upon the rubber strip by simply bending the metal holder upon it in order to lock the strip in place in said holder.

' Installation of the weatherstripping herein fiescribed and claimed is an exceedingly simple Sprocedure. If the door happens to be madey of wood, the metal holder of the weatherstripping is 'simply screwed to the edges of the door. If-k desired, the metal holder of the weatherstripping may be secured to the door jamb instead of to the door proper, although this is not customarily done. If the door is made of extruded aluminum, it will probably have a suitable channel along its several edges into which the metal holder of the weatherstripping may be inserted. :This may be done by inserting the metal holder into the end of each channel and then moving it lengthwise of itself and of said channel. A screw orsimilar fastening device may be inserted throughA the metal holder and into the door frame to prevent longi-v tudinal displacement or dislcdgment of saidl 2 weatherstripping relative to the door. The weatherstripping may be detached vfrom the door by simply removing the screws and slipping the weatherstripping lengthwise out of the door frame channels. Replacement weath'erstrippingv may be installed in the manner above described.

It will hereinafter more fully appear that when the rubber is secured to its metal holder, an airtight and water-tight seal is provided between said rubber and said metal. 'I he rubber strip normally'projects at ananglefof approximately 45 with respect to the metal holder. When the door is closed, however, the rubberA strip bears resiliently against the door jamb. It isthereby bowed inwardly under tension and theangle of 45 is also considerably reduced. Consequently an air-tight and water-tight seal is also provided between the rubber strip and the door jamb. It will further be seen that the method'and means of afxing the metal holder of the weatherstripping to the'door provide an excellent seal between the weatherstripping andthe door. Hence a most adequate and effective weather seal is provided between the door and the'door jamb.

vAn important feature of this invention is'the shape of the rubber strip. The'angle which v'it' bears relative to the door Vjamb is also important. The freeedge of the rubber strip is tapered or feathered to a knife edge and it projects at an angle of approximately 45 -relative to the side of the door jamb. When the door is closed," the knife edge of the rubber strip abuts the door jamb under tension and the rubber strip is bowed to provide a channel between it and the rubber strip holder, fwhichoccupies less than 45?. The wind andy rain are 'accordingly deflected by the knife edgeof the vrubber strip away frointhe door jamb and into the channel last mentioned.v

Preferred forms of the presentinvention'are shown by way of illustration, and not by way of limitation, in the accompanying drawing. in which:

Fig. lois a view similar to that of Fig. 9showing. the rubber strip secured tothe metal holder followingthe last mentionedv bending operation.

The metal holder 2l!V shown in Figs. 2, 3 and 4 isf an extruded strip .of aluminum. It should be understood, however, that although extrued aluminum is. the preferred vmetal for. this construction.A other metals, equally suitable for weatherstripping purposes, may alsoV be .used forv the purposeszof this invention. Zinc andcopper are illustrativeof the other.A metals which. may be employed. Regarding the preferred shape ofthe extrusion, it `will be noted that several well defined portionsor sections areprovided: a. bar portion 2| which. isapproximately half an inch wide-and approximately .O85k ofan inchv thick,l asecond bar portion 22 which is integral with the first. bar. portionV 2l along one of its side edges, said.. second bar portion being approximately a quarter of an inch wide and approximately .040 of aninch thick, the bottom surfaces of4 thetwo bar portions being flush with each other, andailap portion 24 which is somewhat lessfthan a quarter of` an inch wide and .040 of an.inch thick. A narrow neck portion 25 is integral with, bar portion 22 and flap portion,24, alongone of 'theirrespective side edgesand said narrow neck portion is approximately .G of an inch high. A pocket or channel 23 isiaccordingly formed atop bar. 22, between the upwardly jutting shoulder of bar 2l and narrow-neck portion 25. It .will also be noted thatesmall grooves 26 are formed along the under side of yiiap 24.

Rubber strip 28 is approximately five eighths of an inch wide and approximately one thirty second of an inch thick. It is tapered or feathered along one of its edges to form what maybedescribed` as a knife-edge 28. This rubber strip maybe made of natural-rubber orV synthetic rubber orA any' other suitable resilientv and weather resistant material. l

Fig.` 3'clearly shows how rubber strip 21 is insertedinto metal holder 20 preparatory to the fiap'b'ending operation which secures said strip to said holder. More specifically, the untapered edge ofthe rubber strip isA placed in channel 23 immediately adjacent neck portionv 25 of the holder. `The ap 24` isv then bent downwardly from an angle of approximately 45 to a substantially'parallelfpositionwith respect to bar porstrip 4 tion'22. A portion of rubber strip 21 is thereby pressed into channel 23, between downwardly bent flap portion 24 and bar portion 22. Some of the rubber swells into grooves 26 of the flap and some of the rubber is caught between the free edge of the flap and the shoulder of bar 2l which lies opposite neck portion 25. The rubber strip is thereby very tightly secured to the metal holder and its free portion is caused to project at an "angle of approximately-45 above bar portion 2|.

Metal holder 30 has substantially the same l features as metal holder but its construction is somewhat. different. It is made of a strip 3l of aluminum or other suitable material such as copp perzorzinc. This strip is approximately one and seven sixteenths of an inch wide and one thirty second of aninch thick. About fifteen thirty seconds. of yan inch of this strip is bent over upon itself along one side edge thereof and approximately one.. quarter of an inch of said strip. is bent over to theextentof about alongthe otherV side edge thereof. Abar portion 32 is ac'- cordingly formed between the two bends andthe first mentioned bent portion constitutesV a bar 33 whichlies superimposed uponvsaid bar por.- tion 32. ,The second mentioned bentuportion constitutes a flap .34 which is connected to bar portion 32 by meansof a bight 35. Flap 34 is separated from bar portion 32 by an angleof approximately 45. y

Itwill be seen that a channel similar to channel 23 is formed atop. bar portion. 32, between the free edge of bar portion 33 and bight 35. Rubber strip 21 may beinsertedinto said channel with its uptapered side. edge in abutment with the inner curvey of4 said bight 35. Flap 34 may be bent downwardly upon the rubber strip and into `parallel relation with respect to, bar portion 32. The rubber strip is thereby tightly secured to the metal holder. and its tapered side edge projects above bar portion 33 to the extent of approximately 45.

Door jamb 4U and door 42 are intended to illustrate a typical installation. The door frame is made of extruded aluminum and stile 4|.is illustrative of the many extruded forms which are commonly used indoor constructions. The stile is provided with a pair of oiset. flanges 43. and respectively which provide a channel between` them. Figs.. 5 and 6 clearly show how the 'weatherstripping above described may bev at'.-

tached toA the extruded' stile. The weatherstripping is. pre-cut to the length of theA stile and it' is then inserted lengthwise into the channel behind offset. flanges 43 and 44. Theseflangesl engage the metal holder ofthe weatherstripping and prevent transverse, dislodgment or. displacement thereof. To prevent longitudinal dislodgment of the weatherstripping, screwsl 45 may .be employed to secure the metal holder of the: weatherstripping tothe stile and more particularly to the cross bar orweb 45 of 'said stile.

Fig. 5 shows the door in partly open position and Fig. 6 shows it in closedA position. It will be noted that when the door is in open position, the rubber strip 21 of its weatherstripping projects outwardly at an angle of approximately` 45; When the door is in closed position, the rubber strip bears against the doorsjamb with its knife; edge, and since there'is-insuicient-space betweenvv the door and the vdoor jamb for the rulzvberstripI to proj ect outwardly at an angle of' approximately 45; the consequenceis that the rubber-strip is; caused to bow inwardlyinr the manner shownin; Fig. 6. The knife edge of the rubber strip,

pressing against the door jamb, provides a tigh seal which wind and rain cannot penetrate. The Wind and rain are therefore deflected into the pocket formed between the concave side of the bowed rubber stripk and the metal holder, and since there is an air-tight and water-tight seal between the rubber strip and the metal holder, the windand rain cannot enter the house.

It will be understood that the foregoing is illustrative of the basic principles of the invention and that many modifications and changes may be had both in construction and in method and means of installation within the broad scope an spirit of the invention.
