VENTILATING- DEVICE.

Application filed September 30, 1922.

This invention relates generally to means for providing a continuous or at least fairly constant flow of fresh air into closed apartments, and it pertains moreespecially to a device of this kind adapted for insertion into a door in order to afford ventilation therethrough.

One object of the invention is to produce an improved device of the nature set forth which may be composed entirely of sheetmetal, and shall include interspaced members that are individually apertured and carry oppositely directed vanes, the latterl being formed integral with the respective members and so arranged as to permit free circulation of the air, While obstructing vision and preventing the passage of light.

Another object is to providea device of the character described, wherein the -spaced apart members and their respective vanes are associated in a unitary structure, with side pieces attached thereto by means of elements formed from the edges of the members themselves.

A further object is the production of a device of the type specified having a closure capable of controlling the flow of air transversely of the said structure through its apert-ured members, and fitted to slide in guides formed with opposite edges of one of the latter.

Still another object is the provision in a device of the class mentioned of means for noiselessly cushioning the impact of the said closure against the terminals of the slideway within the said guides, at the completion of its travel therein, either to close or open the apertures in the said members.

A still further object is to furnish a practical device of the sort indicated, consisting of few, simple parts, of light but strong, rigid and durable construction; convenient to manipulate; reliable in operation; and easily maintained in working-order, as well as readily fitted to both new and existing doors; besides being amenable to low cost of manufacture.

Other objects and advantages of the invention will become apparent as the specification proceeds.

Vith the aforesaid objects in view, the invention consists of the no-vel combinations and arrangements of parts hereinafter described in their preferred embodiments,

serial No. 591,549. i

pointed out in the Nsubjoined claims, and illustrated on the annexed drawing, wherein like parts are designated by the same reference characters throughout the several views. y v

Brieiiy described, the invention under consideration comprises in its organization a pair of plates disposed inl parallelism a short distance apart one from the other. These plates are slitted each at alternate intervals, so as to form therein facial apertures arranged in staggered relation. The material displaced by the slitting is bent inwardly into the space occurring between the plates and constitutes vanes that are disposed angularly with respect to the two series of apertures. vrIhe free, inner eX- tremities of these vanes are offset beyond one another so as to block the vision and the passage of light from either side of the combined plates, irrespective of the apertures therein, no matter at what angle the,7 may be viewed. Still this is accomplished without interfering with the circulation of air through and across the apertured plates, Interposed ibetween the inside faces of the latter, and associated with the transverse ends of the vanes, are channel-shaped members that govern the spacing of the pla-tes relatively to each other. rlhe edges of one of the plates are carried outwardly past the flanges of the said channel-shaped members and then bent back inwardly in such a manner as to encompass the same, one plate being thereby clamped upon the flanges of the adjoining member. Guides are also formed with the edges of the other plate for a slide having a number of openings adapted to be brought opposite the apertures in the latter and thus controlling the flow of air therethrough. Y This plate is maintained rigidly in position on the adjacent flanges of the channel-shaped members, as well as the said guides, by means of keepers, preferably struck up from it near the edges' thereof and ythence bentover the last-named flanges. The opposite edges of the slide are thickened, as Iby folding the same upon themselves, in order to hold the body thereof at the required distance from the contiguous face of the plate. Besides, the curved extremities of the'folded edges are lconsiderably less than the inside radii of the guides and afford complete freedom of motion to the slide. The guides are stopped up as well as reinforced at their terminals, by retainers holding resilient buffers in place that serve to cushion the impact resulting from the slides movement thereagainst, when reaching the limit of its travel at either end. This naturally contributes to noiseless operation. The outer faces of the slide and of the plate remote therefrom are correspondingly reinforced, intermediately of their respective openings and apertures, by hollow ribsformed in opposed'relation to one another, which permit the use of comparatively light material, without the sacrifice of either strengthor rigidity, in the manufacture of the device. A knob, affixed in plain view to therouter face of the slide, provides a convenient and unobstructive grip for' the manipulation thereof inopening or closing the ventilat ing apertures.

The advantages of they invention as here outlined are `best realized when all .of its features and instrumentalities are combined.

in the one and same structure, but, useful devices may be produced embodying less than. the whole.

It will be obvious to those skilled in the art to which the invention appertains, upon becoming conversant with the details thereof, that the same may be incorporated in several different constructions. The accompanying drawing, therefore, is submitted merely as showing thepreferred exemplification of the invention.

In the said drawing Figure I is a front elevation or outside view of this improved ,Ventilatingdevice, av portion thereof being broken away to.y showA Fig. V is a similarly enlarged fiag mentary end view of. the device as it appears loolting towards the Vright from the:

upper left-hand corner of Fig. l; and

Fig. Vl is a fragmentary,longitudinal section, on the same enlarged. scale, taken from the line Vl-VI of Fig. I, viewed vin theidirection pointed out by fthevertical arrows thereto appertaining.

rlhe reference numerals. L11 and 12 designate `side plates,.which are located acertain distance apart one from the other, so vasto leave Ytherebetween a space A of 'predeterf mined width, depending on the thickness of the door to which the ventilating device is to be applied.

Air guiding vanes 13 are produced in the outer plate 11 by cutting three-sided slits therein, such as are clearly shown in the left half of Fig. l and the right half of Fig. lil. These vanes are bent obliquely inwardly of the space A as indicated in Fig. H, and thus provide elongate apertures 14, leading into the same. intervening between the several apertures, are bi'idgesl, which are reinforced by hollow ribsl, struck up from the inner face of the plate.

Similar air directing vanes 18 are also formed outof the plate 12, but the latter point right angularly inward into the space A, as Fig. l1 shows. However, the ,slitting of this plate produces like apertures 19, sepl` arated bybridges 20. These rbridges of the plate.12f are smooth-surfaced throughout.

The` free, inner extremities of -5 the said vanes 13 and 18 may be offset to such extent that theyl vare made to pass one another out wardly beyond the middle ofthe said space A., as seen to best advantage by reference to Figs. IV and fV. According to the arrangement adopted for the embodiment of the invention herein. exemplified, the apertures 14 and 19, intermediate the vanes in the two setsl and 18, are positioned substantially opposite the bridges 20 and 15, respectively. As shown, the oblique vanes VA13 are made shorter than the apertures 14; from which they are slitted, this is when the space A is of mediocre width. Generally, the wider the plates 11 and 12 are spaced apart, the longer the vanes 13 must be in order to prevent direct rays of Vlight passing through the said apertures 14 and 19, as also to block the sight thereacross.

interposed between the plates 11 and 12, in associated relation with their inner faces and the transverse ends of the vanes 13 and 18, are ,channel-shaped members 22 and 23, which extend ,for the entire length of the. ventilator. These members constitutie spacers that hold the plates 11 and 12 at the predetermined distances apart, and their web portions bound the narrow sides of spaceA left between the said plates, in all instances.

As plainly indicated in Figs. lV and V, the outer longitudinalV portions 24 of the plate 11 are foldedinwaidly around the adjacent flanges 25 of theme-mbers 22 and 23, respectively, and. the free edges 26 of these same portions are made to lie close .against the webs of the saidmembers. AThus. it will be understood, the latter are securely fastened in position.

The opposite flanges 28 .of the members and 23am tied .to the plate 12 by means of lugs; orV ears 29, shorn outv of that part of the plate whichsublies the latter-named flanges,

as represented in Figs. 1V and V. The lugs are first bent up, then laid over and pressed down upon these flanges. In this case also, the free ends or tips of the lugs 29 are made to abut against the webs of the channel-shaped members, so that not only is the plate 12 maintained in proper correlative position with their said webs, but the latter are firmly secured in juxtaposition to the vanes 13 and 1S. T he openings left in the plate 12, after forcing out the lugs 29 therefrom, are indicated at 30, the same being located under the flanges 28 of the channel-shaped members 22, 23 and substantially opposite the smooth-surfaced bridges 20.

The outer longitudinal portions-32 of the plate 12 are folded in the same direction as the corresponding parts 24 of the plate 11, that is, so as to lie outwardly beyond the plane of the former. rEhe free edges 33 of the said portions 32 are spaced from the. plate 12 sufliciently to constitute a pair of guides 34, the extreme outer limits of which are given each a liberal inside curvature, as denoted at 35. lt will be observed that the said outer portions 24 and 32 of the two l 'plates 11 and 12 are situated in approXi mately the same longitudinal planes and form the transverse margins of the ventilator.

1n the guides 34 is fitted a slide 37, translatable lengthwise of the adjacent plate 12. The lateral edges of this slide are preferably reinforced or thickened, as by bending the same inwardly over or upon themselves, in the manner indicated at 38, thereby offsetting the slides body from the plate sufficiently to preclude the rubbing of their entire surfaces one against the other, which would streak and abrade the paint thereon, as also render them liable to stick together. rlhe frictional contact between the folds 38 and the plate 12 is limited to the width of the former and their counterparts on each side of the slide 37 that rest upon the opposite inner faces of the guides 34. It will be noted thatrthe rounded outer edges of the slide are of considerably less curvature than the corresponding inside portions of the guides, so that the former obtains in the latter a liberal freedom of motion, accompanied with lessened friction and a practically noiseless operation.

rEhe slide 37 is provided with a number of openings 40, conforming with that of the apertures 19 in the plate 12, both being similar in outline and arranged to register with one another. The opening 40 are separated by bridges 41, which also are reinforced by hollo-w ribs 42, struck up there from. rhese ribs are of configuration cor-Y responding to that of the ribs 16, previously mentioned, and together they give both sides of the ventilator a like appearance.

At 44 is indicated a manipulating knob for .the slide 37, which may be secured in any suitable manner to one of the ribs 42,`

in plain view of a person facing the door, so `that it can be easily reached whenever it is desired to open, close, or graduate the communication between the series of apertures 14, 19 in the plates 11, 12 and the openings 40 in the said slide.

With the object both of strengthening the guides 34 and providing a stop to limit the travel of the slide 37 in either direction, a retainer 46 in the formof a bar of flattened cross-section is lodged across each pair of the guide members at the ends of the plate 12. These bars 4G may be held inftheir assigned positions by rivets or the like 47, fastening them to the plates.

It will be observed that the extremities of the said bars which enter the guidesV are nicked down, as at 48, and buffers 49, such as blocks of rubber or other resilient material, are lodged thereagainst, as represented in Figs. III and VI. Obviously, these buffers act to cushion the impact of the slide as it comes to a stop at the end of its travel in either direction within the guides, thereby eleminating any noise on that score. It kis understood that when the buffers 49 are undergoing deterioration they may bediscarded and new ones substituted.

The improved ventilator herein described and illustrated is especially designed for insert-ion into the top panel or upper part of a door, as exemplified in Fig. Il (by dotand-dash lines) where B represents the side stiles of a door, and C denotes moldings that serve to retain the device in proper position, besides giving the insert a finished appearance. Notwithstanding this showing, the device can nevertheless be employed for any other appropriate purpose, where it is desiredy to establish a circulation of air across some primary support without permitting direct light rays therethrough, or allowing objects to be discerned or viewed from one side thereof to the other.

It is to be noted that this improved device is wholly metallic inits character, as well as self-contained. vThe transverse ends of the apertures in the front and rear plates, as also of the openings in the slide, are made flush with the inner faces of the channelled members, so that it is an easy matter to blow or clean out dirt from the interior of the space A enclosed by the associated plates and members. There is nothing to get out of order, or endanger by tampering with the same. Such chance as the slide might have of binding or rattling is obviated by the very nature of its construction and arrangement. The ventilator in its entirety may be given a coat of paint to conform to the finish on the door, without'interfering in the least with its successful operation.

While a certain preferred embodiment of this devicev has been shown and'described,

it Will be understood that changes in the form, arrangements, proportions, sizes and details thereof may be made, Without departing from the scope ofthe invention as' defined by the l appended claims.
