Application 'filed February 18, 1922.V Serial No. 537,459.
To 'all iii/0m it may concern:
Be it known that I, ROBERT F. DoLnzAL, a citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois,- have invented certain new and useful Tmprovements in` V\7indeu7 ventilators, of which the following is a specification.
This invention relates to a device for controlling and directing the circulation of air through an open or partially open window and for excluding rain, snow and direct drafts, and has for its object the provision of a ventilator which shall be of improved construction, efficient in operation, and econemica-l to manufacture.
The invention is exemplified in the combination and arrangement of parts shown in the accompanying drawing and described in the following specification, and it is more particularly pointed out in the appended claims.
In the drawing- Fig. 1 is a front elevation of one embodiment of the invention in place beneath a partially open window sash;
Fig. 2 is a Vertical section on line 2-2 of Fig. 1;
Fig. 3 is a horizontal section on line 3-3 of Fig. 1; and
Fig. 4 is a plan view of a blank from which the slatted portion of the Ventilator is formed.
The invention comprises an open or slatted portion formed from a rectangular blank of sheet metal shown at 10 in Fig. 4. This blank is slitted along parallel lines at 11, the slits having right angular extensions 12 at each end thereof. A strip 13 at each side of the blank is thus formed which is left intact.
The side strips 13 are bent along broken lines 111 and 15 to bring the portions 16 of the side strips into approximately horizontal position, as shown in Fig. 2. This will cause the portions of the blank between the lines 11 to assume an overlapping angular position forming slats 17 withdownwardly projecting overlapping portions 18, as shown in Fig. 2. The slatted ventilator thus formed may be supported in any suitable frame and placed in position in the window.
The frame shown in the embodiment illustrated in the drawing comprises a bottom strip 19, a top strip- 20, end strips 21 and 22, and a central brace portion 23. The upper l2O, as shown in Fig. 2. strips 211 may be secured to the end stripsk and lower edges of the ventilator are secured to the top and bottom strips 19 and If desired, vertical 21 and 22 and the base portion 23 to overlap the edges o-f the ventilator and prevent displacement of the central port-ion thereof.
In order to easily insert and remove the ventilator from a window it may be desirable to provide one edge with an adjustable extension comprising a channel-shaped member 25 a'djustably secured in place by a wingnut 267 as shown in Fig. 3. It will be apparent that other forms of supporting frames may be employed and that changes in the dimensions and proportions of the device as illustrated may be made by those skilled in the art without departing from the spirit and scope of the invention. When desired screen wire may be attached to the frame of the ventilator adjacent one face of the slatted portion to prevent insects from passing through openings between the slats.
I claim 1. A. ventilator comprising substantially parallel inclined slats, the top edge of each slat being connected at its end to the end of an adjacent slat intermediate the upper and lower edges of the inclined portion thereof.
2. A ventilator comprising a plurality of inclined slats, the top edge of each slat being connected to the next adjacent slat by a substantially horizontal strip whichjoins the said adjacent slat at a point between the upper and lower edges of the inclined portion thereof.
3. A ventilator comprising a unitary sheet of relatively thin material having parallel slits formed therein to provide a plurality of slats, a portion of said sheet at the ends of said slats being uncut and bent to bring said slats in substantially parallel inclined position with open spaces therebetween' for the passage of air.
4. A ventilator comprising a unitary sheet of relatively thin material having substantially parallel slits formed therein to provide a plurality of slats, the ends of said slats being severed for a portion of their width from the portion of the sheet adjacent thereto, said adjacent portion being bent into substantially horizontal position to form connections at the ends of said slats and to hold said slats in spaced relation to one another and in inclined position to permit passage of air through said ventilator.
5. A ventilator comprising a plurality of spaced inclined slats arranged in overlapping relation to one another, the overlapping portion of each slat having a portion cut from the end thereoic and bent to form a connection with the next adjacent slat.
6. A ventilator comprising a plurality of spaced inclined slats, each slat having a strip cut from the end thereof for a portion of its Width, said strip being bent into a substantially horizontal position and con nected with the upper edge of the next lower slat to hold the slats in overlapping relation to one another.
7. A ventilator comprising a unitary sheet of relatively thin material having parallel slits formed therein to divide said sheet into slats7 said slats terminating short of the ends of said sheet and connecting with short slits extending at an angle thereto Which sever a portion Jfrom the endsfof the slats,
the portions thus Severed being bent to form spacing members at the ends of the slats connecting the upper edge of each slat to the next adjacent slat so that the portion of the said next adjacent slat included between the angularly directed slits overlaps the slat directly beneath it.
8. The process of forming a ventilator comprising the steps of forming in a sheet metal blank substantially parallel slits which terminate short of the edges of said blank and which have angularly directed extensions atthe ends thereof and bending the portions of said blank between said extensions and said edges to bring said portions adjacent said extensions into substantially horizontal position thus forming spacing members for retaining the portions of said blank between said horizontal slits in inclined overlapping relation to one another.
In testimony whereof I have signed my name to this specification on this 11th day of February, A. D. 1922.
\ f ROBERT F. DOLEZAL.
