WEATHER STRIP.

Application filed January 26, 1924. Serial No. 688,838.

ful Improvements in eather Strips, of

which the following is a specification.

My invention relates to improvements in Weatherstrip. One of its objects is to pro- 0 vide an improved Weatherstripadapted to be used to advantage upon house doors, refrigerator doors, casement windows, and for similar purposes. Another object is to pro vide an improved Weatherstrip adapted to close the oints at the corners, as for lnstance to close the joints at the corners of refrigerator doors to prevent the escape of cold air when the refrigerator door is closed, or to render a. casement window or adoor weatherproof. Another object is to provide a re liable all metal Weatherstrip adapted to close joints of the character above specified. Another object is to, provide an improved Weatherstrip actuated by or through the closing of the door or window sash to automatically actuate the Weatherstrip to close the joints upon one or moresides of the door or sash. Another object is to provide an improved and more effective weatherprooi joint. Another object is to provide a resilient Weatherstrip for the above purposes adapted to retain its original shape and its original resiliency for long periods of time.

y My invention also comprises certain details of form and comblnatlon of components, all

of which will be fully set forth in the de scription of the accompanying drawings, in which:

Fig. 1 is a vertical sectionaldiagram' through the frame of a casement window' with the sash open or omitted and with my improved weatherstrip in place thereon in idle position.

Fig. 2 is a view similar to Fig. 1 showing the window sash closed and the Weatherstrip in active position closing the window joints. Fig. 3 is a view similar to Fig. 1 through a door frame showing the door partly open and the Weatherstrip in idle position.

Fig. 1 is ,aview similar to Fig. 3 showing the door'closed and the Weatherstrip in ac tive position to close the joints.

Fig. 5 is a perspective view of one of the lower corners of thedoor with the weatherstrip attached thereto.

Fig. 6 is a perspective view of one of the door Weatherstrip members detached.

Fig. is a diagram illustrating one manner in which the joints are closed at the corners of a door or window sash. 1

Fig. 8 is a sectional detail illustrating a modification of Figs. 1 and 2. i

Fig. 9 is asectional'detail showing its application to an inwardly opening sash.

' The accompanying drawings illustrate the preferred embodiments of invention in Figs. 1 and 2 of which 16 represents the frame of a casement window and 16 represents the easement sash hinged to the window frame and opening outwardly therefrom. To the top, bottom and opposite sides of the window frame'are fastened sections of Weatherstrip as shown in Fig. 1.

As shown in Fig. 1 the respective sections of weather strip are formed by bending or folding a strip of resilient sheet metal upon itself lengthwise of the strip atu17, and bending said folded strip into an angular cross-sectional pattern substantially as shown in Fig. 1. One edge 18 of the strip is also preferably folded upon itself to provide a smooth finish or binding for said edge 18. The lip or section 19 of the Weatherstrip is attached to the jamb or face 26of the window frame at intervals bymeans of' a series of screws or nails20. The

middle sections

21 and 22 of the Weatherstrip rest one against the other and against the joint face 24 of the window frame. The Weatherstrip section 25 is bent with reference to the sec .tion 22 so as to normally extend away from ends when the window sash is closed, but

are preferabiy left the full length and rethe strip shown in Figs. land 2 are atlied upon to close in upon the corner of the window sash from the dotted line position to the full line position Fig. 7, and to yield at 27 at their meeting faces outside of the window sash corner to effect close joints with the respective corners of the window sash or door su'l ista ntial'ly as sh'own in Fig. 7.

As the window sash 16 is closed into the window frame as shown in F 2; the face 28 of the sash first contacts with the edge- 189 of the Weatherstrip section 25, and serves to firmly press the sections-25- toward and against the section 19 until the window sash reaches itsfullolosed posit-ion iand is latched shut thereby effectinga olose' and'resi lient and weather proof: oint between thesection E25 and the face 28 ofthe Window sash.

Pressure by the windowsash-against the we atherstrip section 25 :due to the 1 confined positionof the -weatherstrip causes the apexv of' angle '30 of the Weatherstrip to act sas a; pivotal z p'oint or or rock thereby forcingthe edge 17015 the section 22 away from the face 24 of the 'window' frame and-against the edge r face32 of thewindow sash to form a resi-lient and weatherproof joint betwceneaid section '22 and the face-32 of the window sash upon the four faces of said window sash. The -edges of the sec-tions 21: and 2-2- being united at ll'gcansesEthe' section 21 to be also drawn away from ihe-face24 of the.

window frame together with the'section The section 19'being held with close-joint to the window 'frame,and the sect-ions and 22"beingheld-"resiliently iii-close contact with the

faces

28 and 32 of: the window sash, whereby I am enabled-ts secure and main-- tain a thoroughly effective wind and waten proof joint applicable to door or casement windows.

- In Fiq'sl 3', 4,"5 :and 6, I havc illustrateda modiica tion -2'1dapted;for use in connec- For such doors strips 35,-corresponding totached to the top and bothsides of the door frame 41 and'adapted-to be engaged by the door 420 when the door IS'ClOSGCl in substantially the manner hereto-fore described in Figs. 1 and 2. To the bottom of-the door is attached by means of screws or nails 36 a section 43 embraced between the sections ,39

and 40, and a section 44 projecting down wardly fronii the door 'at an angle'so as to fulcii'u-m upon which the sections and 22 turn be engaged by the threshold strip 34 when the door is brought to closed position. The

free end of the strip section 40 is preferably extended along the lower face of section 44 and its lower edge 49 bent upwardly over the lower edge of the section 44 to assist in holding

thestrip member

42, 44 in place with reference to the strip member 37,and also to provide a smooth finish or binding; 'for the lower edge of the section 44.

Opposite ends

45 and 46 of the section 43 are turned upwardly and enter recesses 47 cut 'in opposite edges of the lower end of the door. I also preferably provide metal face 3 plates 48 outside of the end sections-45 and 46, which face plates are rigidly attached to the edges of-the. door at the bottom thereof.

lVhile the door is in open position the strip members '37 and" 42 due to their rcsiliency assume substantially the position showninFigffi. When the door isclosed the lower edge '49 and. the lower edgeof section 44' encased therein contact .withrthe raised portion of the threshold strip' 34 thereby causing the apex of angle 50 at the junction of the

sections

43 and 44 to act as a fulcrum on '

edges

38 and 49 areTesiliently engaged with the upper face of the threshold strip 34 with suflicient tension to effectually [close t'liejoi'i' t between the lower edge the door and the upper {face of the threshold member 34.

- Ordinarily the resilient engagement atthe edges 38 and 49'is sufficient to springthe metal and therebysomewliat increase the distance between the edges 38 and 49above normal which tends to yieldin'gly keep the joint betweenv the door and threshold member closed.

If desirod the threshold stripfi'l lmay be metal faced.

The section 61 of Fig. 8 corresection 25 of Fig.1 and is sponds to the adapted to be engaged by the door or window when closed and forced toward the scction 53, which in turn causes the sections 56, 57 and 60 to move together upon the angle 64: serving as a fulcrum to cause the free edge 58 of section 57 to move toward and contact with. the edge of the door or window to close the joint.

In Fig. 9 I have illustrated the application of my improved Weatherstrip to close the jo'nts where the sash of the, easement window is hinged to open inwardly, and in which the operation is substantially the same as heretofore described for Figs. 1 and 2.

I also employ my improved Weatherstrip by applying a portion of the strip-members to the door f nine or window frame and another portion to the door or window sash, as for instance by applying two vertically positioned strip members to the opposite sides of the door frame or window frame and in connection therewith applying two horizontally positioned strip members one attached across the top and the other across the bottom of the door or window sash. The adjacent ends of the respective horizontal and vertical strip members are tr'mmed to pass each other without frictional engagement, but so as to close the joints at the corners with. practically no open spaces. If desired strip members such as shown across the bottom of Figs-3 and 4.; with the recesses 47, projections to'and 41-6, and face plates l8 may be employed also across the top of the door as well as across the bottom thereof.

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

What I claim is:
