VENTILATOR.

, Specification of Letters Patent.

Application filed July 17, 1909. Serial No. 508,192.

Patented ltiz'ar;15,1910.

To oll who'm it may concern:

Be 1t known that I, VILLIAM H BARR, citizen of the United States residingavt Brooklyn, in the county of Kings and State of New York, have invented certain. new and useful Improvements in Ventilators, of which the'following is a specification.

This invention relates to improvements inwindow ventilating devices and embraces the construction of means for ventilating a room adapted to be removably secured toa window. A v

- One ofthe objects of the invention is the construction of a simple expansiblewindow ventilating device capable of bein attached to a window and. held in place t jamb teeth formed on. the device.-

Another object of the invention is the construction of improved means for ventilating a room consisting of a windowengaging device formed for the passage ofairtherethrough made "of two interlocking sections,

ereon by each section being formed out of a single section of material and connected together without soldered joints.

With the above and other objects in view the invention embraces certain combinations,

constructions and arrangements of parts, clearly illustrated in the accompanying drawings, in which,

' Figure 1 is an inside view, in elevation, of. awmdow provided wlth my improved Venthlating device, Fig; 2 is an enlarged view partly in section and partly in elevation showing the device mounted in position on a window, Fig. 3 is a front elevation showing the two sections of the ventilator before being joined together, Fig. 4 is a top plan view thereoffFig 5-is a vertical sectional view'of the two ventilator Sections oined together, and Fig. 6 is a detail plan view of a portion of the ventilator, showing the manner-in'which the deviceiis forced intoengagement with the side. of a window frame- I V v Y j .Refe'rring to the accompanying drawlngs,

' 1 denotes a windowfframe, which maybe of any-desired construction, and whichembraces side members 2 and abottom memher 2.

The ventilating device embraces two interlocking sections 3 and 4. Each. section v of the ventilator is formed vwith an open end and a closed end. The section 4 is made.

slightly smaller thamtlie section 3'in order that it can fit in the same. The upper'por'tioni,

or wall 5 of each section islprovided with perforations 6, for the passage of air therethrough, and the front wall 7 is formed imperforate. On the upper wall 5 of each section a rolled edge 8 is formed, the rolled edge of the section 4 being adapted to enter the roll of the edge of section 3. The bottom wall 9 of each section is also formed imperforate. The bottomv wall 9 of the inner section 4; is formed with a depending edge 10, adapted to engage with the bottom de-' pending edge 11 on the bottom wall 9 of the section 9, said edge 11 being turned up, or formed U-shape' in order that the edge 10 may ride therein. The two engaging edges 10 and 11 are adapted to engage with the inner side of the bottom member 3 ofthe window frame; On the end of-each sec tion a wing 12 is formed, said wing being preferably provided with a series of teeth 12, adapted to engage the side member 2 of the window frame; Each section is made out of a single piece of material, the ends 13 of each sectionbeing formed or attached to the front wall 7. The top wall 5 of each section is formed with a bendable flap 14, adapted to entera slit 15 inthe end wall 16, and the bottom wall 9 is formed with a bendable flap 17, adapted" to enter a slit in the remaining end wall 16, and to be bent against theinner side of the end walls.

The device may be positioned on the bottom. or on the top of the window and when secured in position will allow for air to enter a room without permitting flies or other obnoxious matter to pass into the room. The air passing through the openmgs or apertures 6 and through the chamber of the ventilator into the room.

By expanding orcontracting the two sections upon eachother the device can be ad'- justed to fit any ordinary window frame.

By making the device without soldered joints the same can be shipped in a knock down 'shape and folded together very Having described my invention I claim and desire to secure by Letters Patent 1. A ventilator formed of two telescopic sections, said sections having top, bottom, back and end walls, the four walls of each section being integral, said top walls being perforated, said endw'alls depending flanges on said bottom walls, said end walls having- .a toothed flange set at right angles therewith, saidtop walls having their free-edges set in interlocking rolls, as shown and described.

2. A ventilator formed of two telescopic sections, said sections having top, bottom, back and end walls, the four walls of each section being integral, said bottom walls being narrower than said top walls, said back walls being set being perforated, said end walls having a 10 toothed flange set at right angles therewith,

at an angle, said top walls said top walls having rolled interlocking edges to contact a window sash, said bottom walls having depending interlocking flanges,

as shown and described.

In testimony whereof I afiix my signature, 1.5

in presence of two witnesses.
