EMIL TIETZE AND GOTTLIEB SCHLER, OF NEW YORK, N. Y.
VENTILATOR.
Application filed February 17, 1925.
To all whom t may concern.:
Be it known that we, EMIL TIETZE and GoT'rLrnB Sor-IULER, citizens of the United States, and residents of the city of New York, borough ot the Bronx, in the county of Bronx and State of New York, have invented a new and Improved Ventilator, ot' which the following is a full, clear, and exact description.
This invention relates to ventilators and more particularly to a window or sash ventilator, an object of the invention being to provide a ventilator ot' this character which will constitute a portion ot the window or sash, which will be air and water-tight when closed, which can be opened to any desired degree, and which will shed rain and snow when open.
A further object is to provide a ventilator which constitutes a portion ot a window or sash, the several movable slats thereof being of glass mounted in suitable supporting members and having improved operating means which enable the slats to be opened to any desired angle, and which when closed securely lock the slats in closed position so as to prevent unauthorized movement of any or all or the slats by some one outside ot the window.
llVith these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements ot parts which will be more fully hereinafter described and pointed out in the claims.
Tn the accompanying drawings `Figure 1 is a. view in elevation of a window or sash equipped with my improved ventilator;
Figure 2 is a view in longitudinal section on the line 2 2 of Figure 1, showing in dot and dash lines an open position of the ventilator;
Figure 3 is a fragmentary view in section on the line 3-3 of Figure 1;
Figure 4 is a perspective view of a slat holder.
1 represents a window or sash or any `frame which may support at its end portions glass panes or lights 2 and 3, respectively, the intermediate portion between the panes 2 and 3 providing an opening for the accommodation of our improved ventilator, which will be hereinafter described.
Serial No. 9,790.
It is of course to be understood that we do not limit ourselves to the position of the ventilator relative to the sash as it may be at any desired point of the sash.
In the sides of the frame 1 metal plates 4 and 5, respectively, are secured and countersunk. To these plates 4 and 5 slat holders 6 are pivotally connected. These slat holders 6 have longitudinal grooves 7 therein receiving the slats 8 which are suitably packed as shown at 9 to make them air tight and prevent rattling` or possibility of breakage.
The slat holders 6 at one side of the frame 1 are provided with perforated lugs 1 0 which receive screws 11 secured in the plate 5 and provide pivotal mounting for said holders. The holders 6 at the other ends of the slats S are made with rearwardly projecting arms 12 which are pivotally supported between the ends on screws 13 secured in the plate 4. The free ends of these arms 12 are pivotally connected to a link 14, and, as the pivotal means, I have shown screws 15 which are projected through the arms and screwed into the link 14. This link 14 `compels all of the arms to move together and hence compels all of the slats to move together.
A locking lever 16 is pivotally connected between its ends to the link 14, as shown at 17, and has a laterally offset shoulder 18 adjacent its inner end which is adapted to engage the inner edge of the link 14 and limit the pivotal movement of the lever 16 in one direction.
A coil spring 19 connects the outer end of this lever 16 with a iixed arm 20 on plate 4 so as to hold the lever in normal position and exert a pressure on the lever and the link 14 to hold the slats in closed position or return them to such position.
The inner end of this lever 16, when the slats are in closed position, lies against the upper portion of one of the slat holders 6 so as to prevent any possibility of some one outside of the ventilator manually moving or pivoting the slats. This lever therefore constitutes an automatic lock as well as a means for opening the ventilator slats.
A chain 21 is secured to the free end of lever 16 and has, preferably, a ring 22 at its lower end for the reception of a inger to exert a pull on the Qllall .t0 open the ventilator, and when the ventilatorV is Vopened to the desired degree any link of the chain 2l is canghtlover a lined pin or 4hooliriont'he frame ly to hold the ventilator in this position.
l/Ve Would calll particular attention-tothe shape and construction ot he slat holders 6 l one of Which is shown in perspective in Figure 4. Y Y I V The outer members of the grooved slat i holders extend ,be-low the inner i members thereof, and`v have webs 24, thereon ,against Whieh the edgesoi the slats are seated.v The inner member lot each slat holder 'hasan .enlargement 25 thereon Whichwivhen the ventilators -areiclosed lies in a plane above the uppen'edge of theslat belovv so that any f attempt to move a slat upwardly will only canse the same toengage theenlargement 25st theslat holder above and, prevent such movement... 'lhe'nppermost sla-t may be confined 1n any. approved manner but ive have shown as a simple means small angle brackets 26 securedto-y the. nppermostislat vholders andoprojeoting over ythe edge of the uppermost slat.
Figures `l andQ-illustrate clearly; the position or' the slats when,closed-showing that the several*l slats. and their hold-ers` are so shaped that they provide atight. Aclosure which is securelyflocked byv the `lever le.V
l?urthermore,` as above explained, the slats are securely lookediand held in place against either pivotal or other. movement, by van un- :authorized person; outside oiA the Window'.
When it iis, desired to open the ventilator it is simply necessary to exenta pullf on the cha-m21, this pull lirst movingthe,looking lever 16 Aont of looked positionand then a continued pnll on they ohainwvillxdraw the t link ll downwardly and .canse-all of the sla'tsfto pivot and move to the desired,angli-v lar. positions-and held in such position, when one. ot the links oi' the chain 21: .iscaLight A over the pm or hook 23.
Then the; chain is released'the spring 19 Willreturn fthe parts to olosedand locked position.-
Various slight changes andyalter-ations might be Vmade' in the general form `of the pants described 'Without departingirom our invention, and hence Wedel not .limiteuri selves to theprecisle details set, forth but con- Sider ourselves atiliberty to make suoli slight changes and alterations as `fairly fall Within the spirit and scope of the appended claims.
We claim: l
l. The combination with a Window frame having transparent panes and an opening therein,a plurality of` overlapping transparent slats adapted to close the opening, holders at the ends of the slats pivotally connected tothe trame, a link connecting the holders at one side of the frame and oompelling them to move together, and. a pivoted lever on the link engaging one ofthefslat holders and. l'nnctioning to `lock the slats in closed position.
2. The'combination with a Windowframe,
having' transparent panes` and an opening therein, a plurality ot overlapping/,transparent slats adapted* to lclose the opening, holders at the ends `ot the slats pivotally connected to the trame, a f link .connecting The combination with a yframe having` an opening therein, pla-tes fixed to the sides oi `the frame, slat holders pivotally connected to the plates, glass slats in said holders oi' a Width to overlap eaehpother and form a tight` closure `ivhcn in one extreme position, arms on the slat holders at one side of the trame, a linh connecting said anms, a lever pivotally connected between its ends to the link-and having-a shoulder'thereon engaging the link When moved to unlocking,`
position, a spring connecting Lthe lever with one of saidplates and exerting a pull thereon to` hold the lever inposition back of one. `of the slat holders and also to hold the slats in closed position, and means for moving the` lever to operate the slats.
