6 Claims.
This invention relates to ventilators for doors, transoms, Windows, ceilings, floors, walls or other openings.
An object of this invention is to provide a ventilator structure which will eliminate drafts and substantially all light.
Another object of this invention is to provide in a ventilator an improved louver construction in the form of substantially V shaped louvers and rockable shutters or closures extending from the inside of the angle of one louver in the direction of an adjacent louver for regulating the passage of air therebetween.
A further object of this invention is to provide in a ventilator of this type an improved means for operating the regulating members as a unit.
A further object of this invention is to provide in a ventilator an improved frame structure of channelconstruction and an improved means for securing the louversto the frame structure so as to provide a rigid frame and louver structure.
A further object of this invention is to provide in a ventilator animproved louver which is so constructed as to protect the shutter in any position of the latter-so-that the shutter cannot be readily bent or damaged.
To the foregoing objects and to others which may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts as will be more specifically referred to and illustrated in the accompanying drawings wherein is shown an-embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.
In the drawings:
Figure l is a detail front elevation of a ventilator constructed according to an embodiment of this invention,
Figure 2 is a sectional view taken on the line 2-2 of Figure l,
Figure 3 is a sectional View taken on the line I and an upper channelled-shaped frame member 55 I3. The channel members H and 12 are disposed in opposed relation with the channels thereof opening outwardly as shown in Figure 4. The upper channel member i3 is disposed in an inverted position and is provided at the opposite ends thereof with extensions M which are formed as continuations of the opposite sides thereof and which extend through slots or openings l5 formed in the webs or bights I6 and I! of the channel members I! and 12, respectively. The
extensions M are adapted to be welded or otherwise fixedly secured to th parallel sides l8 and 19 of the channel members I I and I2, respectively.
A plurality of superposed and vertically spaced apart parallel louvers generally designated as 20 are fixedly mounted within the frame structure it. Each louver 26 is formed in an inverted V- shaped construction as shownin Figur 3 and each louver '20 at the apex thereof is formed with a longitudinal bead or arcuate channel 2i. Each louver 23 at its lower edges or the lower edges of the divergent side 22 thereof is formed with a vertical extension or side 23. The space between the vertical extensions -23 is slightly less than the width of the webs or bights i6 and ll of th channel members it and 12. The extensions 23 at the opposite ends thereof are formed with outwardlyextending ear 24 which are adapted to engage through slots 25 and 26 which ar formed in the webs l6 and I7, respectively, and these arms or extensions 24 are disposed in face abutting relation to the inner sides of the legs or side members [8 and [9 of the channel members H and [2.
The ears or extensions 24 are adapted to be spot'welded or otherwise fixedly secured to the inner faces of the legs l8 and I9 respectively. The opposite ends 21 of the louvers 20 are adapted to abut against the inner faces of the webs or bights l9 and if desired may be welded or otherwise fixedly secured thereto.
A plurality of shutters or valve members 28 are disposed between adjacent pairs of louvers 20 and each shutter 28 comprises an elongated plate 29 which is formed at its upper edge with a barrel 36 through which a shaft 3! engages. The shaft 3| is adapted to be fixedly secured within the barrel 3'iiso that rocking of the shaft 3! will efiect rocking of the shutters 28. The opposite ends of the shafts 3t are adapted to be journalled in the central portions of the webs i6 and IT. The shutter 28 also includes a right angularly disposed extension 32and an offset extension 33 which is disposed in parallel-relation'with the body 29 of the shutter 28. Th offset extension 33 is adapted to contact with a succeeding or adjacent bead 2| as shown in Figure 3 when the shutter 28 is in a closed position. When the shutter 28 is in a fully open position, the extension 33 will assume the position shown in dotted lines in Figure 3 and will contact with an adjacent vertical side member 23.
In order to provide a means whereby the shutters 28 may be operated as a single unit, I have provided a link 34 which is fixedly secured to an end of the shaft 3|, there being as many links 34 as there are shafts 3| and shutters 28. When the shutters 28 are in a closed or vertical position the links 34 will be disposed in the positions shown in Figure 2. The links 34 are connected together at one end thereof by a vertically disposed connecting bar 35 which is pivotally secured to the adjacent ends of the links 34 by pivot members 36. The opposite ends of the links 34 are connected together by a second connecting bar 3'! which is connected to the opposite ends of the links 34 by pivot members 38. The bars or connecting members 35 and 31 are disposed in a parallel relation and will be so disposed in any position of the shutters 28.
At a point intermediate the length of the bars 35 and 31, I have provided a shutter operator generally designated as 39. The operator 39 includes a plate 40 which is pivotally connected as at 4| and 42 to the connecting bars 35 and 31 and is also fixedly secured as at 43 to an end of one of the shafts 3|. The plate 40 has formed integral therewith a stem 44 which extends loosely through an elongated slot or opening 45 formed in an adjacent side member or leg I9 of the channel member 2. A handle or knob 46 may be fixedly mounted on the stem 44 so that rocking of the operator 39 will effect rocking of the shutters 28 as a unit to either open or closed position.
In the use and operation of this ventilator structure the frame structure I0 is adapted to be fixedly mounted in a desired opening and the operator 39 is positioned in a convenient location for operation of the several shutters 28. The frame structure I0 is disposed with the louvers 2|] in the position shown in Figure 3 so that any water or moisture striking the louvers will readily flow downwardly therefrom on the outer sides thereof. Any air passing between adjacent pairs of louvers 20 will initially move upwardly between the confronting or adjacent sides of adjacent pairs of louvers and will then be turned downwardly on the opposite side of the ventilator structure so that this ventilator will prevent drafts of air passing directly therethrough. The formation of the louvers 20 in substantially V-shape also provides a protective structure for the shutters so that these shutters will be substantially entirely enclosed within each louver and will not be subject to damage.
While I have shown the operator 39 mounted at the right end of the ventilator structure shown in Figure 1, it will be apparent that this operator may be shifted to the opposite end of the ventilator structure, where desired.

1. A ventilator comprising a U-shaped frame disposed in inverted position, a plurality of parallel spaced apart inverted V-shaped louvers fixed in said frame, a shutter swingably supported from the apex of each louver having a width to extend down from the inside of the apex of one louver to engage the top or outside of the apex of an adjacent lower louver, and a common operator for said shutters.
