To all whom it may concern:

Be it known that I, TILLIAM F. GUL- NERICH, a citizen of the United States, and a resident of Meriden, in the county of New Haven and State of Connecticut, have invented a new and Improved Ventilator, of which the following is a full, clear, and exact description.

This invention relates to ventilators, and has for its principal objects to provide a ventilatoradapted to be attached to a window, and to permit the ingress of air into the interior of a building without causing a draft, at the same time keeping out all objectionable foreign matters and substances,

and to providesuch a ventilator with means for regulating the influx of air to the extent desired. Such objects I accomplish by the means hereinafter described and illustrated in the accompanying drawings, in which similar characters of reference indicate similar parts throughout the several views.

In the drawings, Figure 1 represents a front elevation of a ventilator embodying my invention attached to a window, shown partly broken away; Fig. 2 is a plan view of the ventilator shown in Fig. 1, enlarged;

Fig. 3 is a vertical longitudinal section taken on the line 3-3 of Fig. 2; Fig. 4 is a vertical transverse section taken on the-line 44 of Fig. 2; Fig. 5 is a similar view of my invention to that shown in Fig. 4, with the guard or shield closed; Fig. 6 is a fragmentary section of a front elevation of my device showing a shield and locking mechanism therefor; Fig. 7 is a longitudinal seotion of a sliding latch and connecting parts; and Fig. 8 is a perspective view of a latch for holding the guard or shield in place.

As illustrated in the drawings, 1 represents a window casing having sashes 2 of ordinary construction connected therewith, and provided with window panes 3. The sash is also preferably provided with a pane of glass 4 shorter in length than the adjacent panes 3, and the lower edge of said pane bears against a bracket 5 extending longitudinally of the ventilator. The bracket. 5 may be attached to the upper plate 6 of the main frame of the ventilator in any suitable manner, or if desired may be formed integral therewith. The upper plate 6 is preferably formed integral with a front plate '7 arranged at an acute angle to-the plate 6, and with said Specification of Letters Patent.

plate 6 extending lengthwise of the ventilator. The ventilator is also preferably provided with a bottom plate 8 which is secured in any suitable manner at its inner margin to the window sash. End plates 9 are attached to the longitudinal plates of the ventilator or formed integral therewith. The upper plate 6 and front plate 7 of the ventilator are provided with apertures 10 which are protected by a screen 11 preferably arranged on the inner side of said top plate 6 and front plate 7 for the purpose of preventing objectionable foreign matter from passing through said apertures. A slide is mounted upon the top and front plates of the ventilator, and is preferably formed of an upper plate 12 and front plate 13 bent at an acute angle to each other and having their edges held and guided in grooves or ways 14. The upper and front plates of the slide are provided with apertures 15 corresponding with and adapted to register with the apertures 10 of the top plate 6, and front plate 7, so that when the apertures of the slide are brought into position to register with the apertures of the main frame or top and front plates of the ventilator, air is permitted to freely pass through the frame of the ventilator into the interior of the building. By moving said slide longitudinally of the main frame of the ventilator the area of the apertures 10 of the main frame may be varied so as to regulate the quantity of air that may be permitted to pass through the ventilator.

The slide is so constructed that if desired the openings 10 in the main frame of the ventilator may be entirely closed. A shield is pivotally mounted upon the main frame of the ventilator by means of studs 16, and said shield consists of a front plate 17 and lower plate 18 preferably formed integral with each other and with end plates 19, as shown in cross section in Figs. 4 and 5. The lower plate 18 of the shield is preferably provided with a latch 20 which is held normally pressed outward by means of a spring 21, said latch and spring preferably being inclosed within a casing 22 attached to the lower plate 18 ofthe shield. The outer end of the latch 20 is preferably provided with a lip 23 adapted to engage the edge of a latch 24. The latch 24 is pivotally mounted on the main frame of the ventilator by means of a stud 25 so as to permit the free end of said latch to have a lateral movement. The latch 24 is provided with pins adapted to engage a small aperture 26 on the lower plate 18 of the shield. The free end of the latch 2-1 engages a slot 27 formed in the lower plate 18 of the shield. Saidfree end is also provided with a finger or pin 28 extending transversely of said latch 24 to prevent the withdrawal of the free end of the latch through said slot 27 of the shield. The latch 21 is also preferably provided with a finger piece 29 by means of which the latch 24 may be adjusted and the front plates 17 .of the shield may also be provided with a finger piece:

or knob 30 for moving said plate, if desired. A deflecting plate 31 may be formed on or attached to the upper portion of the main frame or casing of the ventilator to break the force of the wind and to prevent the wind from striking directly onto-the aper-i tures 10 of the front plate or casing of the ventilator. The lower plate 8 of the mainframe of the casing of the ventilator is pref erably inclined upward from the window sash for the purpose of deflecting the air upward toward the apertures 10 of the easmg.

13 and be operable independently of each the corresponding aperture of the adjacent side of the casing may be omitted.

hen the device is in use a current of air entering the interior of the casing of the ventilator is deflected upward by the inclined plate of the ventilator and confined to some extent within the interior by the defleeting plate 31, and passes through the apertures 10 of the casing to the interior of the building. The quantity of air desired to pass through the casing may be regulated by the slide 12-13 and the admission of air through the casing may be entirely shut off by said slide when desired. In addition to regulating the quantity of air desired to pass through the casing of the ventilator by means of said slide the shield l718 may be also used for that purpose. When the shield is in an open position, as shown in Fig. 4, it has but little effect in controlling the passage of air through the casing of the ventilator, but when in a closed position, as shown in Fig. 5, the lower plate 18 of the shield limits the quantity of air that can pass through the apertures 10 of the front plate 7 of the casing, and the upper plate 17 of said shield when in such position acts as a deflector on the air passing through the aper- Having thus described my invention,
