7 ANDREW L. BIKER, or FAIREIELI), CONNECTICUT.

VENTILATOR.

Application filed April 13, 1923. Serial No. 631,785.

To all whom it may conceive:

Be it known that ANDREW BIKER, a citizen of the United. States, and resident of Fairfield, in the county ofFairfield and Stateof Connecticut, has invented certain prevent a direct view through the ventilatorfrom one side to the other of the door and to prevent the direct passage of air currents through the closure. V I I A further object is .to provide a ventilator including spaced apart louvers capable of being incorporated in the opening of a door or the like to close the same without necessity offitting the louvers to said opening. A further object is to provide a ventilator which can be installed in openings of variable size in doors or the like without altering the elements of the ventilator or fitting them to the door, the construction of the elements making the ventilatingclosure capable of being installed in an opening: of greater. or less size, within limits as will apiearr 1 A still further object is to provide anovel and improved article of manufacture of the present character which can be furnished to the trade in two main units to be installed by unskilled workmen, the units being so constructed as to make it impossible to instal the ventilator for use in any except the way it is intended to be installed. I Another object is to provide a ventilator consisting of two main units oneof-which can be arranged upon one side of an opening and the other of which can be arranged upon the opposite side of said opening, and devices for securing the units to each other and against the surfaces of a door or'the like adjacent the opening.

Another object is to provide a ventilator constituted by two units one of whichconsists of a louver and the other of which consists of a louver with simple slide, and devices adapted to connect the louvers with each other and to clamp the louyersagainst oppositely disposed surfaces adjacent an opening in a door or the like without entermg or in any way marring'the surfaces of the door or the like. v

Anotherobject is to provide a ventilator which can be secured in openings of doors or the like which vary in thickness, that is, I

in doors having theiroppositely disposed surfaces adjacent their openings to be closed arranged at variable distances apart, without necessity for adjustment or alteration ofthe main units of the ventilator.

And yet another. object is to provide a I ventilator of the present character having a simple slotted or apertured slide associated with a louver in novel and improved manner to be'easily manipulated to allow openings through the ventilator or to close said openings. I V

VVith the above and other objectsin view, the invention comprises the construction,

arrangement and combination of, parts as now to be fully described and as hereinafter to be specifically claimed, it being under stood that the disclosure herein is merely illustrative of the principles of the inven- .tion and meant in no way in a limiting sense, changes in details of construction and arrangement of parts being permissible so long as within the scope of the appended claims. I

Inthe accompanying drawing formingla part of this specification,

Fig. l is an elevational view of a door or the like as seen from the inside'of a build ing, showing the improved ventilator applied touse; j V

Fig. 2 is a sectional View on line 2-2in Fig. 1, looking in the direction of the arrows;

Figs. 3 and 4. are perspective views of the outer and'in'ner louvers of Figs. 1 and 2, showing the oblique flanges of said louvers extending in different direction from the plates or bodies of the louvers;

Fig. 5 is a perspective view of the slotted or apertured. slide to be associated with one of the louvers of Figs. 3 and 4; and

Fig. 6 is an enlarged fragmentary sectional view on line 66 in Fig. 1.

With respect to the drawing and the charvacters and numerals of reference indicated thereon, A denotes a door or the like with opening B to receive a ventilating closure,

and C andD denote,respectively, 'the outer and inner surfacesof said door adjacent the opening B. The ventilator of the present invention is adapted to be clamped against the surfaces and D to serve as a closure for said opening.

Numerals 10 and ll -denote-louvers adapted to be clamped against the surfaces C and D, respectively, of the door A, each louver, naturally, being of the general configuration of the opening B, rectangular as shown.

Each louver may consist of a single piece ofmetal suitably shaped for its pun pose, although either or both louvers could be constructed differently. That is to say, each louver 10, ll'consists of a desirably flat, rectangular plate or body 12 having a continuous, desirably L-shaped margin or doub'le flange 13 comprising a continuous flange 14 adapted to lie in opening B when the ventilator is put to use and a continuous flange 15 adapted to engage a surface C or D as the'case may be. The margin or double'flange 13 need not be L-shaped, but each "flange 14 should be of uniform width forits full length'in order that the plates or bodies 12 of the'louvers 10, 11 will be parallel with each other, and each flange 15 should be parallel with the p-latesor bodies 12 in order that the flanges 15 will lie snugly against the surfaces C, D, as will be understood.

The continuous flanges 15 can be plain or can have any design intended to enhance the appearance of the ventilating closure.

Each plate or body 12 of the louvers 10, 11' is provided with slots or apertures 16 for the passage of air through the ventilator, and adjacent each slot or aperture 16 is a preferably obliquely disposed flange 17, all of the flanges 17 extending from the face of eachp'late or body 12 opposite the L- shaped margin or double flange 13. As disclosed, the flanges 17 extend nearly the width of the plates or bodies 12 and are constituted by'metal struck from said plates or bodies 'to produce the slots or apertures 16.

In order that there can be no direct line of vision through the louvers when the elements of the ventilator are assembled, the slotsor apertures 16 of the different louvers are arranged in staggered relation, and all ofthe oblique flanges 17 extend toward the same side of the ventilating closure, as best shown in Fig. 2 and Figs. 3 and a, the flanges of Fig. 2 all extending toward the right of the ventilator and the flanges of Figs. 3 and .-all being adapted to extend toward the left-when the louvers are assembled to prod the closure.

Numeral 18- represents a slotted or apertured slide adapted to be suitably associated with one of the louvers. This slide may be'associated with the inner louver 11 in the following manner: A lower strip 19,adja cent the bottom portion of the L-shaped margin 13, preferably extending about the length of the plate or body 12, may be -drawn as at 20 to provide annular flanges 21 adapted to-engage the face of said plate or body 12 t0 space the lower strip a suiticient-distance from the plate or body 12 to allowinsertion ofthelower edge portion of the slide 18 between said plate or body and strip, and hollow rivets 22, passing through openings in the annular flanges and through openings 29 in theplate or body 12 of the louver 11, may be utilized to secure the lower strip 19 to-said louver 11. SeeFigs. 2 and 6. After the slide is so inserted, an upper strip 19,'adjacent the'upper portion of the L-shaped ma'rgin 13" and extending approximately the length of the plate or body, may be securedto saidplateor body in the exact manner of securing the lower strip toconfine the upper edge portion of the slide. The slide isthus confined in the depression defined by the L-shaped margin and permanently associated with the louver 11, its sidewise movements, obviously, being limited by the annular flanges 21 or by the side portions of the:L'-shaped margin. As shown I utilize three-sets of "devices'to hold each strip 19 to louver 11. Evidently, any number of strip retaining devices can be employed.

The slide 18 has apertures or slots 23 extending the greater part of the width'thereof and arranged to correspond with the apertures orslots in the'plate' or body 12 of 'the louver 11. A manipulating handle 24,

desirably arranged centrally of the slide, allows for ready adjustmentof theslide to open'or close the apertures or slots through the louver 11. The upper andlower edges of the slide maybe cut away'as'at 25 (Fig. 5) in order that there will-be no interference by the'strip retaining devices when the slide is manipulate'dlfrom one side toward the other of the ventilating closure.

The louver 10 may constitute a single unit of the ventilator, while the louver 11 with slide 18, strips'19, and hollow rivets 22 retaining the strips to. louver 11, may-consti tute another unit, these-beingthe two main units of the ventilating closure.

Numeral "26 denotes bushings, which may be carried by the louver lO, having threaded openings 27-togreceive screws 28-adapted to pass through the hollow rivets 22 to. hold the unitsof the ventilatorto each other, it

being understood that the arrangement of the bushings26 upon the louver l0 corresponds with the arrangement of the'hollow rivets in the louver 11.

The two main units constructed as illustrated and described canbe' furnished to the trade. It is apparent that-any unskilled 'workman can install the units, placing one of the louvers so that-its continuousfflange 15 engages the surface C-of the door A and the other unit sothatitsflange 15 engagesthe surface 1), with theeontinuous flanges 1 1 and. plates or'bodies '12 lying adjacent each other within the opening B. Evidently, no fitting of the units in the opening is required, the continuous flanges 14 being capable of being spaced a greater or less distance from the wall of the opening B.

Several different arrangements could be employed for insuring that workmen cannot install the ventilator in any except the way it is intended to be installed. As shown, one of the strip retaining devices including a hollow rivet to receive a louver clamping screw (the upper intermediate one) is ofl center, so that there is only one way that the units can be joined.

When the louver clamping screws 28 are manipulated to draw the louvers toward each other, the continuous flanges 15 of the.

Lshaped margins 13 are drawn against the surfaces C and D of the door A and the flanges 15 are adapted to lie snugly against said surfaces without marring them.

The bushings 26 are adapted to limit the tension which the flanges 15 can exert against the surfaces of the door or the like and when the ventilating closure is set up the open ends of the bushings are preferably situated close to (almost contiguous with) the plate or body 12 of the louver 11 (see Figs. 2 and 6). When the ventilator is to be inserted in a door having thickness greater or less than that of the door illustrated, bushings and screws 28 suitable to the thickness, longer or shorter than those shown, may be utilized.

It is evident that the portion or margin 13 of either or both louvers 10, 11 could be of configuration different from that shown and could be a separate piece of material secured to the louver and against a door or the like in any manner, as, for example, by the screws 28, or either of the portions or margins 13 could be omitted. In this latter event, screws (not shown) passing through the portion 13 utilized and entering the door or the like could constitute the means for incorporating the ventilating closure in the opening ofthe door or the like, and all of the units of the ventilator could be assembled before they were furnished to the trade.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is:

1. In combination with a structure having an opening and walls adjacent said opening, a ventilating closure comprising spaced apart louvers adapted to cover said opening, each louver including a plate having apertures and flanges adjacent said apertures and a double flange attached to said plate and constituting the margin of each louver,

each double flange comprising a continuous flange adapted to lie in said opening and a continuous flange adapted to be contiguous with a wall of said structure, an apertured slide associated with one of said louvers and arranged within its double flange to open or close the ventilating apertures of said louver, and means for drawing said louvers toward each other and against said walls.

2. A ventilating closure comprising spaced apart plates each having ventilating apertures and flanges adjacent said apertures, the apertures of the different plates being arranged in staggered relation and all of the flanges of the different plates extending toward the same edge of said closure to preclude direct vision therethrough, a

double flange about the margin of each plate and adapted to extend beyond the wall of an opening to be filled, an apertured slide per manently associated with one of said plates,

and means whereby said plates can be drawn toward each other to secure said closure in said opening.

3. A ventilating closure comprising spaced apart plates each having ventilating openings with oblique flanges, the openings and flanges of the different plates being arranged in staggered relation to preclude direct vision through the closure, a flange about the margin of each plate and extend ing therefrom in a direction opposite that in which the oblique adapted to lie in by said closure, a

flanges extend, said flange an opening tobe covered second flange about each of said last mentioned flanges, said second flanges being adapted to lie adjacent oppositely disposed walls of a structure having said opening, and means for drawing said marginal flanges of the different plates toward each other to clamp said second flanges against said walls.

4. A ventilating closure as specified in claim 3, wherein an apertured ventilating member is situated within one of said marginal flanges to open or close the ventilating apertures through said plates.

5. In a ventilating closure, a plate having a marginal flange, spaced apart strips secured to and spaced from said plate, and an adjustable member situated between said strips and'plate, each strip being spaced from said plate by annular flanges integral with said strip and being held to said plate by hollow rivets entering said annular flanges and plate.
