Specification of Letters Patent.
Patented Dec, 1, 1514.
application filed July ll, i918. Serial No. 778,460.
To. all whomit may concern j Be it known that I, A-ccnsr-ll. Krrnz, a fill-12GB of the United- States, residing 1n the borough of ll-lanhattan, city of New lorlr,
opening for the outgoing air is not maim tained. In theuse of ventilators ofthis old typc sudden drafts,- dueto wind or other atmospl eri "conditions outside of the room, will rush-4i ,through the opening designed for the egress of air. This produces the disagreeable 'down-dr'afts of cold airlwhen the sir egress --is located at the top of the wina air inletis located atthe 'botwindow. This also results in a derangement-of the desired currents of air and also interferes with the inward passage of air through the inletopenings. In this the top and bottom of the window. 'wcll known that drafts of cold air from the 'old type of ventilator it is manifest that if the sudden drafts of air enter the room through both the inlet and outlet openings the ventilating system or plan is destroyed, resulting in the discomfort of the persons in the room from the fact that the vitiated air cannot escape and from the further fact that drafts of cold air enter the room from both It is top of a, window make it practically impossible for a person to sit near the window without grave danger to his health.
It is the "main object of this invention to provide a system of ventilation in which.
both the air inlet and air outlet will be self- :i-djusting and will respond to a v atmospheric condition outside of tho and prevent sudden inward drafts of vcold air through either the air inlet or the air outlet.
Another object of the invention is to pro vide a ventilating system which will maintain a movement of air through the room in a constant direction from the air inlet to the anoutlet, without regard to the variable atmospheric conditions out-side'fof the rdom to be ventilatd- Another object of the invention is to provide ventilating devices whereint-he air outlet will so respond to changes of atmospheric conditions that it will close said air outlet and-preront inward drafts of cold air therethrough. I I It is also the object of this invention to provide means whereby the air inlet will sorespond to atmospheric changes outside-of the roorn'to be "entilatedthat it will materially reduce the area .of the inlet but which will not completely close it. *The re sult of this is that air will be entering the rocmat all times, the area of the inletvarymg in response to the atmospheric-changes outside of thero'om. I
The invention, therefore, contemplates the use of an air inlet and an air outlet, the areaof the inlet 'varyingin response to atm'ojs; pheric changes, such as .wind outside of the window, but at all times maintaining an opening throughwhich air Jim) pass into the room; and a device controlling" the outlet of air from the room, said outlet-varying in response to atmospheric changes outside of the room, such as wind,this, outlet'b eing capable of closing entirely to abs olutelyprevent any drafts of cpl-d air rushing into the I room throughrthe ail" outlet. Thcre'sult of this will be an air pressure in the room andas the outlet device is usually located at the top or the window said airpressure will tend to constantly maintain. said outletpdevioe open. It is-manifest that thedraft of cold air tendin t c-enter ,the room through, the air outlet must first overcome the pressure from within the roorn' and the. pressure within the room will immediately open said air inlet the instant: the dominant outside I .f j 109- pressure is relieved; v
In the drawings, Figure 1 is a vertical sectional view of a window with the ventilating devices in position, said devices-being shown in end view; Fig.2 a s'nnilar view on an enlarged scale, the ventilating devices bel05 ing shown in cross sectional v1ew;,F1g. 3 a
facevicw of the air outlet device, a portion or the said device being shown in vertical sectional VlQ W to more clearl illustrate its construction; and 'Fig. 4 a s milar yie v of 1 10 the air inlet device, a portion of said device being shown in vertical sectional View to more clearly illustrate its construction.
Referring to the various parts by numorals, 1 designates the window casing which may be of any suitable form; 2 the upper sash and 3 the lower sash. These sashes are provided with the meeting rails 4 and 5; and the upper sash is provided with the top rail 6 and the lower sash with the bottom rail 7. The meeting rail 5 of the upper sash is provided with a felt strip 8 which is adapted to bear on the glass of the i lower sash and to prevent currents of air passing into the room between said meeting rails.
The outlet device 9 is located at the top of the window frame outside of the top rail of the upper sash, said device being permanently secured to the Window frame by any suitable means. T he inlet device 10 is lo cated at the bottom of the window outside of the bottom rail 7 of'the lower sash, preferably resting upon the window sill and being 2 rigidly secured in position by means of screws 11 which pass through upwardly extending flanges 12 at the ends of the frame of the device. The inner surfaces of both the inlet and outlet flush with the outer surfaces of ne bottom and top rails, so that said devices will not' interfere with the'free movement of the sash.
'ihe outlet deviceronsists of a box-like casing 13 having aperforated outer vertical fans 14 which extends entirely across the window. The bottom 15 of this case is hin ed at its inner edge, as at 16, a spring 17 ing provided to normally hold said bot-torn n its upper closed position. By
means of this hingedbottoin any dust or dirt which accumulates within the casing may be readily discharged therefrom. The upper portion of the inner face of the case is open to form the air outlet 18. Along the lower margin of this outlet is secured a felt strip 19 which bears against the outer face of the top rail 6, H-S-Sl'lOWZi clearly in Fig. 2. Within the case v13, at't-he top thereof 1s pivoted a depending gate or valve 20. This gate is 59 preferably made of aluminum or other extremely light material impervious to air. This gate is preferably mounted to swing very freely on its pivots so that very light currents of air will swing it from its open to its closed position, and so that it will readily fall by gravity to its fully open posi tion, as will more fully hereinafter, appear. Stops 21 of felt or other suitable material 7 are preferably secured tot-he ends of the cas' G0 ing'in position to be engaged by the gate 20 when the said gate is in its vertical normally open position. T he felt strip 19 is ex tended into the case 13 and its inner edge is adapted-to be engaged by the lower edge of the gate when the saidgate is swung inevices are practically.
wardly to its closed position. On the ends of the case and in position to be engaged by the ends of the gate felt strips 22 are secured so that when said gate is in its closed position the opening 18 will be completely closed to prevent air passing into the room through the outlet device. The gate 20 may be formed as a single gate throughout the length of the ventilating device, or the device may be divided into sections by partition 23 and a gate provided for each compartment formed by said partition.
It is manifest that air under normal 0011- ditions may pass out through opening 18 under the gate 20 and out. through the perforated outer wall 14: of the case 13. It is also manifest that should there be an inward rush of cold air due to wind or other atmospherie conditions outside of the window the extremely light gate 20 will swing to its closed position thereby preventing-any air passing into the room through the outlet device. Assoon', however, as the normal conditions have been restored the gate 20 will swing down to-its open position, thereby restoring the normal condition of the outlet device.
The inlet device consists of a casing having a ri id top, a perforated inner vertical -wall 24; an outwardly and downwardly curved outer wall 25, and a horizontal perforated intake 26 extending inwardly from the lower end of the wall 25, said intake being about mid-way the height of the casing. The inner end of the'perforated intake 26 is 0 connected to a vertical imperforate wall 27 which extends to the bottom of the casing I Within the casing is a vertical imperforate wall 28 which extends longitudinally of the casing parallel with the perforated inner 5 wall 24, this wall 28 together with wall 27 forming a tree h-like compartment 29 within the casing. The bottom of this compartment inclines inwardly and downwardly to a longitudinally extending discharge open- .7
l/Vithin the casing 10 at the top thereof is pivotally mounted a depending gate or valve 1 31. This gate is formed of extremely light material such as aluminum and is mounted to swing freely on its pivots. Stops 32 are provided in the casing to be engaged by the gate ill-when said gate is in its normal vertical position. Stops 33 are arranged clp'se to the upper end of the wall 28 in a ositic it 123 to be engaged by the lower end of tie gate 81 when said gate is swung inwardlv toward the wall 28. The gate and the wall are so proportioned that when the gate is swung inwardly to the stops 33 the passage tor the we
