ATTD RN EYE Patented Oct. 10, 1950 UNITED STATES PATENT OFFICE VENT SHUTTER GRILLE Lewis J. Reynolds, Sr., Bethany, Okla.

Application July 1, 1947, Serial No. 758,426 1 Claim. (01. 98- 29) This invention relates to a ventilator or shutter grille for insertion in the vent openings of building foundations.

An object of the invention is to provide a device of this character which, applied to a vent opening in a building foundation, will permit ventilation of the building during the summer months and prevent cold air from entering the vents during the winter months.

It has been the usual practice to close the vents in building foundations with boards in the winter time to prevent cold drafts from entering the vents and also to prevent the cold from damaging the plumbing under the house. In summer time, these boards are removed for cooling the building, and either stored or destroyed until the winter months, when they are again replaced, if they have been stored, or new ones found if they have been destroyed. Over all, such a practice is much of nuisance when rose bushes or other shrubs block the vents.

The present invention has, therefore, been designed to eliminate this undesirable method of closing these vents, and provide at the same time a device that is easily manipulated, once it has been installed.

With the above and other objects and advantages in View, the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed and illustrated in the accompanying drawings in which:

Figure 1 is an elevational view of one form of the invention installed in the air vent of a building foundation;

Figure 2 is a sectional view on the line 2-2 of Figure 1, with the device in open or ventilating position;

Figure 3 is a sectional view on the line 3-3 of Figure 1;

Figure 4 is an elevational view of the rear or sliding plate of the device;

Figure 5 is a sectional view on the line 5-5 of Figure 1;

Figure 6 is the same as Figure 2, with the device in closed position and Figure '7 is a sectional view of another or modified form of the invention.

Referring more in detail to the drawings, the reference numeral I0 designates a ventilator constructed in accordance with the invention, that is to be placed over the vent opening II formed in the wall I2 of a building.

In Figure 1, there is shown a form of the invention that is to be used where a conventional iron grille I3 has been inserted in the wall during the construction of the wall I2.

This form of the invention comprises an exterior or outer plate I4, which is of a larger size than the opening I I, and is placed over the opening l i and extends beyond said opening, as shown in Figure 2. The outer marginal edge of the plate I4 is curved inwardly as at I5 to provide a more attractive appearance, and firmly seal the edge of the plate at its contact with the wall.

A screw bolt I6 is provided with a clamp l'l at its inner end to engage the grille I3, and nuts I8 on the outer end of the screw, which extends beyond the plate M, will, when tightened, hold the plate I4 firmly in position in contact with the wall I2.

The plate I4 is provided with vertical rows of relatively spaced diamond shaped openings I9 having half diamond shaped or triangular shaped openings 20 at the top and bottom thereof, which, at the top, have their apexes pointed downward and at the bottom have their apexes pointing upward.

Intermediate of the openings I9 are triangular ceived in the tapped opening 24 in the rear or inner sliding plate 25.

The plate 25 is slidably mounted in the track ways-26 secured to the upper and lower longitudinal edges of the plate I4 by welding or the like.

The plate 25 is provided with the vertically disposed relatively spaced rectangular shaped openings 21 which, as in Figure 2, coincide with the rows of openings I9, 25 and 2I to permit air to enter therethrough or to close these openings as in Figure 6 by coinciding with the plate I4 intermediate of the openings I9, 20 and 2 I.

A slot 28 in one end of the plate 25 sleeves the bolt IE to permit full movement of the plate 25 to close or open the openings I9, 20 and 2| as desired.

The knob 23, being a screw knob, can be tightened to draw the plate 25 in close contact with the plate It to prevent rattling of the plate 25, and cut off the entrance of all air into the building through the ventilator.

The form of the invention shown in Figure '7 comprises a ventilator 3B which is set into the opening II in the wall I2 as is the grille I3 during the construction of the wall of the building.

Thus the outer ends of the outer plate 3| are embedded in the wall I z to retain the ventilator therein. The plate 3| is provided with openings similar in all respects to the openings [9, 20 and 2!, and the screw knob 23' passes through the plate 3| to be received in the inner sliding plate 32 having the vertical openings 33 therein.

In this instance, the plate 32, along the upper and lower marginal edges thereof, is provided with inturned flanges or trackways 34 whic'hengage over the upper and lower longitudinal edges of the plate 3| for slidably mounting the plate 32. The knob 23 operates in the same manner as knob 23 to prevent rattling of the plate 32, and the plate 3| is slotted as is the plate I4 for the receiving of the knob 23'.

There has thus been provided a form of ve'ntilator which is adapted for use with walls of buildings already constructed and for walls of buildings under construction.

It is believed that "the operation and construction of the ventilator will be apparent to those skilled in the art, and it is to be understood that changes in the minor details of construction, arrangement and combination of parts may be resorted to, provided they fall Within the spirit of the invention and the scope of the appended claims.

Havin thus described the invention, what is claimed as new and desired'to be secured by Letters Patent is: g

A building ventilator of the type described, for use in conjunction with a vent opening formed in the wall of a building and having a grille fixed in said opening, comprising an outer plate and an inner plate in contact with said outer plate, means for detachablyanchoring said outer plate to the grille in fixed relation to said opening, said means comprising a screw bolt, a clamp at the inner end of said bolt adapted to removably engage the inner surface of the grille, and nuts on 'the outer end of said screw engaging the outer surface of said outer :plate, trackways formed on the rear of said outer plate along the longitudinal upper and lower edges thereof, said inner plate being slidably mounted by means of said trackways, vertically disposed parallel rows of relatively spaced diamond and triangular shaped openings in said outer plate, closed portions of said outer plate intermediate said rows of openings, vertically disposed parallel rows of relatively spaced rectangular shaped openings in said inner plate and means passing through said outer plate to be threadably received in said inner plate for moving said inner plate to position said rectangular openings therein in alinement with the openings in said outer plate to permit the passage of air therethrough, and to move said rectangular openings into alinement with the closed portions of said outer plate to prevent the passage of air through the openings in said outer plate and said means adapted to be tightened to retain said inner plate in firm contact with said outer plate when said plates are in said latter position.
