Serial No. 323,826.

This invention relates to ventilator construction; more particularly to metallic ventilators for framed members, such as doors, windows, skylights, or the like.

My invention is more particularly directed to the provision of a ventilator, whether used in conjunction with doors, windows or skylights, which functions efliciently as a ventilator to permit the ready circulation of air,

to givethe privacy of opaque members and at the same time provide efficient fireproof construction. Still more particularly, this invention is directed to the provision of all metal construction ventilators for doors,

5 windowsor the like, which may be used for to provide a ventilator for doors, windows and the like which includes louver members,

each of which is individually formed and assembled in multiple units, as desired, to constitute a ventilating area of any predetermined slze.

It is still further an object of" my invention to provide a ventilator construction, suitable for use with a framed member, such as a door or window, the ventilator including 'tions, the stacked units including members which are formed so as to engage the stile or rail of the frame which is part of the door individually formed louver members which are assembled in nested or stacked relationship relatively to the 'stiles andrails of a frame member, the louver members being so formed as to be held in engagement with each other and the stiles and rails, particularly when these members are made of metal, without employing solder, rivets or other connections.

It is a still further object of my inven- 7 tion to provide in a ventilator construction louver members in the nature ofhollow metal units which may be maintained in'nested or stacked relationship to provide air circulating spaces therebetween, the units being formed with inclined air deflecting surfaces to assure proper circulation of air and depending aprons to preventdirect view through the portions forming the spaces between adjacent units, :the units being so 1 formed that they may be maintained in engaging relationship to each other without necessity for employing soldering connections. It is contemplated by my invention to provide in a ventilator, louver members which will have all the requisite rigidity incident tobeing formed as part of a door or WlIlClOW, extreme lightness of weight, characterized by forming the louver membersof sheet metal, bent into hollow units includa ing angularly disposed air deflecting surfaces, having downwardly disposed space guarding aprons, the members being so formed whereby they may be arranged in nested relationship and maintained spaced without employing soldering connections to hold the members in position whereby a fireproof ventilator may be provided, including elements which may be decorated or met proofed "beforeassembly into the composite structure. Still further objects of my invention reside in the provision of a ventilator which may bejassociated with a frame construction, such as the stiles and rails of a door or window,-the ventilator including louver members formed of hollow, metallic units, formed of bent sheet metal, including portions thereof formed to permit nesting or stacking in spaced relationship without the necessity of employlng soldering connecor window, 7

Other objects of my invention include the provision of a. ventilator which is fire proof, rigid, inexpensive to manufactureand easy to assemble.

bodying "my invention 1 00 Jigure 2 is an enlarged View taken on a line 2-2 of F lgure 1;

niguie 3 1s a section talren on a line 3-3 of Figure 2;

Figure 4 1s a perspective view showing the elements of my device partially assembled;

higure 5 1s a perspective view of a detail. Making reference to the drawing, I have illustrated my invention as applied to a door 10, whose upper panel 11 is provided with ally triangular in cross section. The sheet.

metal forming the blank is preferably first bent along the fold line 16 to provide spaced side walls 17 and 18, thereby providing an internal ridge. The metalis then outwardly bent along the corners 19-19 at substantially I right angles to the ridge, thus forming the arms 20 as the base of the triangular section unitv previously referred to. The metal is then bent downwardly along thecorners 21 and then reflexively bent upwardly along the edge 22 to provide the aprons 23. The

remainder of the metal of the blank is then angularly bent to form the deflecting surfaces 24. The metal is thenupwardly Ver tically bent at the apex 25 to provide the tips 26 and 27, joinder being effected by the excess portion 28 which forms the lip andv which is crimped intoengagement over the tip 26. The crimped portion 28 is bent'over thetip 26 for only a portion of its length, to leave the tips 26 and 27 uncovered, thereby providing open-ended members for purposes which will appear as this description proceeds.

'angularlv The members'above described are arranged to be disposed in nested or stacked relation, with the apex of one member adjacenta base another immediately'above it, in numbers as described.

For maintaining the members so stacked in spaced relationship, Tprovide a riding post extending from the apex of one 11111 0. to a point adjacent the base of the next unit im inediatelyabove the same. It is preferred that this riding post be constructed of a metallic strip, as shown in detail in Figure 5, comprising an enlarged louverengaging porenerally trian ular in sha e and an 5-: v V Z:

extended apex 31. These members are con veniently formed by bending a strip of sheet metal refleziively upon the fold 32,: to; form branches 3333. The strip is then bent outwardly at 34, 34 and then in- I wardly again at 35 to provide the spaced base members 36.

A strip so formed may be inserted into each end of a louver member to dispose the extension 31 between the tips 26, 27 and to rest the base members 36, 36 upon the base portions 20,20 of the louver unit, with the spaced ends 36 to either side of the centering ridge below the fold 16 previously described. Louver units so assembled, with a riding post each end may be stacked in numbers as described, with the extension 31 fitting within the centering ridge 16, thus providing spaced portions 37 between each of the louver units. It will be observed that stacked units, as described, may be held rigidly disposed within the rabbeted portion of'the stiles and rails of the door. It is preferred, however, particularly where an entire metal structure is provided, to maintain the'louver units in stacked relation by end channel members 38. F or this purpose the channel members 38 are made of a size to frictionally engage the louver units at the aprons 23 and it is preferredithat the lowermost unit be fixedly connected with'the channel 38 andfor this 'purpose, orifices 39, are provided in alignment with similar orifices on the lowermost louver unit, through which there is passed rivets 40.

These channel members, it will be understood,

are provided to each Cl'lCl'Of the louver units; tocompletely encase the open-ended hollow members. For completely assemblingthe stacked units and attach the same to the upper rail 15, itis preferred that the uppermost louver unit .13? be formed withan upwardly directed channel 25. T This is preferably formed by extending the metal from' the deflecting surface 24 to provide upwardly directedflanges 26 and 27, the channel being completed by the beaded, refiexively folded flanges 28. The channel so formed on the uppermost. louver member 13' serves to centrally space the louver member within the channel 38, previously described and may, at the point where it engages the channel 38,: be provided with oriiices 41 in alignment with similar; orifices 39 upon the upper portion of the channel 38, through which maybe passed rivets 42 to permanently assemble the louver units and channel. 7 i It will thus be observed that I have pro vided a novel ventilator ofextreme light ne ss of weight, even when made ofmet'al and withthe partslso constructed that they may be assembled inT'spa'ced relationship without solder connections. It will be further 010- served that as I avoid the use of any solder. connections between the louver unit-s and'the channel holding the same in assembled relationship, that I may ornamentor rust proofthese; members before assembling the same, without any danger of marring the coated surface. f i

It will be further observed that the assem:

bly as provided may be afiixed in position without danger of separating the joints and the assembly may therefore be hammered into position.

It will also be observed that by arranging the members in stacked relationship, as described, the overlapping aprons, enveloping the lower constricted portion of a louver unit immediately thereunder, there is provided a ventilating surface which will be free from any objectionable draft creating openings. Similarly, the assembly as provided may be used in positions where one side of the ventilator is to be exposed to the weather and the ventilator will adequately serve its intended function Without ingress of rain or the like.

It will further be observed that by the simple connection between louver units and the simplicity in design thereof, the ventilator space may be built of any desired length and width, without special tooling, further effecting economy in that the units may be maintained in stock and assembled Within a fairly wide range of tolerance.

It will be further observed that due to the similarity in construction on both side faces thereof, the units may be assembled in the door without regard to the position of the unit, the appearance being the same on opposite sides of the door construction. Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent, is
