ILLINOIS, AssICNoR To BERRY VENTI- LATOR COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF MAINE.

wlNDow-fvENTlLAToR.

To alt Loh/0m it may concern:

Be it known that I, MILTON H. BERRY a citizen of the UnitedStates, residing. in C icago, county ofCook, and State of Illinois, have invented certain 'new and useful Im provements in Windovv-Ventilatore.

My invention relates to that class of de- 'vices'which are intended to permit O'I' the raising of a Window Without subjecting the room to a direct draftcaused by the opening.

The invention 'is designed as an improvement upon my invention described in my application Serial No. 304,611-,'and has for .its Object to provide means to prevent the Weight of the Window-sash from coming on the vent the air at the ends of the ventilator, a has for its further object to construct a ventilator which may beused in Pullman or other cars and which will ermit of the ventilation ofthe car Without t e admission of dirt, cinders, &c.

My methodof accomplishing the foregoing may be more readily understood by having reference to the accompanying drawings,

which are Vhereunto annexed and are a part ofl this specification, in Which- Figure 1 is an elevationof a Window frame and sashhaving my improved ventilator attached thereto. Fig. 2 is an end elevation of the ventilator proper. Fig. 3 is atop view of designed so that it may be attached to thesash of'thewindow and remain attached at all times, it being so constructed as tobe au- L tmatically adjusted by thejraising'4 and low. 45.

Similar reference-numerals refer to similar parts throughout'the entire description.

As shown in the drawings, my invention is ering of the sash.' F1 1 shows awindoweframe'havingsashes 2 an 3 movable therein. In Fig. 4the ventilator is s hown attached tothe sash 3,' although 1t 1s obvlous'that it may be attached to-either theupper orlower sash. vIt is' constructed, as` v better seen'in the detailed view of Fig. 2,' of a i top and bottom 5 and 6, the top 5-be1ng provided With a large number ofminute perfospecification of Lettere Patent.

One of the difficulties of providing a venti- -lator adapted to open and close with the opening and-.closing of a window is caused by the fact that if the Window is raised to a height equally to the two sides 7 and 8 they windowisclosed they must, either be ushed inwardly or are liable to be broken ythe pressure exerted onthe sash. I prevent this y means of stops 14, which are composed of two members 15 and 16, which are attached to the top and bottom ofthe ventilator by pins or pivots 1 7 at their extremities. These strips are pivotally attached to each other by meansv ofy a pin or pivot 18. The upper member 14' is further provided with a -shoulder .19', this shoulder being adapted to vmembers7 and 8' into the position shown in Fig. 2 thevshoulder on the member I15 pre- Will assume a vertical position, and when the oq engage` the member 16 .as the windoW -is I r raised, with the result that when thewin- .V dow has been Open suiliciently to bring the ventslits openngany farther by engaging v the .member` 16.v The result-is that the memsition, Land-conse u ently it is impossible-for them to be in suc a position as to'be Asubore being'in position to close with the win# OW, v Y: 4Vlhere the ventilator is to be used in trai-ns.

l With the said sash, its inner Wal top 5 and covering the pei'forations therein, the mesh of the screen being small' enough to prevent/"the admission of cinders Without excluding the air. When the window is raised and it is desired to close the openings a-t `the end, themetal strip 11 may be inserted in the slot 10 and will then assume the position shown in Fig. 2, in which it is apparent that all the end is closed with the exception of a small portion at the pointof union between the members 7 and 8 and the to and bottom, respectively. When the win( ow is closed, the strip 11 is automatically ejected from the slot 10 and assumes the position shown in Fig. 3.-

An inspection of the drawings discloses the fact that the ventilator is to be at` all times on the interior of the window and when closed; as shown in Fig. 7, lies entirely within the-Window, and is consequently easy to get at at any) and all times. The members 7 and 8 may e provided with glass panels, if a transparent ventilator is desired, or they ma be formed of metal plates.

aving described my invention, what I regard as new, and desire to secure by Letters Patent, is-

The combination With a window'having m'ovable sashes, of a ventilator adapted to open and close with the o ening and closing o the window-sash, sai ventilator being foldable and having. a horizontal perforated plate attached to the sash, the whole ventiatorsetting inside of the sash, said horizontal perforated plate being covered with a fine screen, for the purpose set forth, substantially as described.
