To all whom it may concern: I

Be it known that I, THOMAS A. JnNKINs, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvementsin Ventilators,

of which thefollowing is a specification.

This invention relates to improvements ventilators of vitreous material and more, especiallyto moulded or blown louvered glas plates for window frames and the like.

The primary object of the invention resides in the provision of a single or double glass late with ventilating openings therein ormed with louvers of various, geometrical configurations.

One of the objects of the invention is to produce a window ventilator having two complementary, louvered plates, oneadjnstable with respect to the other to regulate the draft of air through the louvers and in addition. prevent the passing of rain or dust therethrough.

A still further object of the invention is to produce a lass plate ventilator of the type above set fimth; wherein the louvers are so arranged that the vision is completely checked, yet permitting the free passage of a predetermined draft of air to a room, car or other enclosure as the case may be.

The invention will behest understood from a consideration of the following detailed description taken in connection with the accompanying drawing specification, with t e understanding, how ever, that the invention is not confined to any strict conformity with the showing in the drawing, but may be changed and modified solong as such changes and modifications mark no material departure from the salient features of the invention as expressed in the subject matter being claimed.-

1 attain the above objects and others in the accompanying drawing wherein Figure 1 is a front View of the ventilator.

Fi 2 is a sectional view taken on the line A of Fig. 1. I

Fig. 3 is a front view of a modified form of the invention.

Fi 4 is a sectional B- of Fig. 3. l

Fi 5 is a vertical sectional view taken on thelme CC of Fig. 1 showing a single view taken on the line plate;

Fig. 6 is a similar sectional view showing a double set of plates; and

forming a part of this Fig. 7 is a vertical sectional viewjshowiiig Elie p' ates in their adjusted or closed pesir Referring now to the drawings wherein'eo like numerals designate corresponding'parts throughout the several views, numeral l 4,,- des gnates-a substantially rectangular frame whlclf'may be constructed of metal or wood,

and 2 represents a retaining head for the ca vitreous plate 3, it being understood that the plates may be moulded or blown. v r

In the form of the invention shown by Figs. 1 and 2, it will be observed that the louvers 4 extend substantially across the w dth of the glass plates and from the top and bottom thereof, the said louversbein downwardly curved in the form. of a he so that the draft of air will enter the openmg 7 through the passage 8 in the manner shown by the short arrows as clearly set forth by Fig. -5 of the drawing. Numeral' 9 designates a comflementar glass plate also provided with 'ownwardfy curved louvers in the form of hoods, as above described, so so that when the respective plates are contiguously disposed w th each other the louvers of each plate will produce a substantially semi-circular air passage to permit the draftto enter atl and through the opening 13, as suggested'by the short arrows of Fig. 6 of the rawing.

Where it is desimd toregulate the quantity of air or the draft through the plates, l have provided a thumb. screw 6 operable through suitable guides secured to the frame land to the movable plate 3, whereb the passage may be regulated as desired. For instance, in the manner shown by Fig. 7 of the drawmg, it will be observed that the

flat portions

10 and 11 of the plates are of a length to close the openings-in one plate relative to the other and thus entirely exclude the air and prevent the admission of rain. l

din-the form of the invention shown by Figs. 3 and 4 of the drawing, it will be observed that the louvers 5 are spaced throughout the width and length of the plates and of course, the stationary and movable plates of the frame are adjustable in the same relation as described in connection with Figs.

1 and 2 of the drawings' It will be quite apparent that the configuration or form of the louvers may take various geometrical designs and while I have shown the same in the form of a hood or downwardly curved spherical louver, I do. not desire to be limited to this exact form, but, contemplate other fanciful and artistic designs to accomplish the same purpose.

Between the respective plates as indicated at 14, I also propose to introduce a dust filtering fabric to exclude foreign matter from enterlng an enclosure, the same belng particularly adapted for use on railroad sleeping cars where the adjustable louvers perform the double function of regulating the draft or quantity of air and completely checks the vision thus dispensing with the necessity of using shades.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that any modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages.

at I claim is:

1. A ventilator element for building constructions and the like comprising two 0pposed complemental sheets of vitreous material having cqually spaced openings, each of said sheets having its outer face provided with integral laterally projecting and depending curved louvers opposing said openings, each of said louvers having its top and sides closed, said louvers extending transneeaeea versely of the sheets and rovidin'g means for directing air throng the openings, means connected with the outer face of one of said sheets for shiftin it relatively to the other, the portions 0 said sheets between the louvers being of a width to close the openings of the sheets when one sheet is shifted relatively to the other.

2. A ventilator element for building constructions and the like comprising two opposed complemental sheets of vitreous material having equally spaced openings, each of said sheets having its outer face provided with integral laterally projecting and depending curved louvers opposing said openings, each of said louvers having its top and sides closed, said louvers extending transversely of the sheets and providing means for directing air through the openings, means connected with the outer face of one of said sheets for shiftingit relatively to the other, the portions of said sheets between the louvers being of a width to close the openings of'the sheets when one sheet is shifted relatively to the other, and a stationary flat foraminous body interposed between said complemental sheets.

I In testimony whereof, 'I afiix my signature hereto.
