REMOVABLE CLOSURE FOR VENTILATING OPENINGS IN HOUSE FOUNDATIONS Filed Feb. s, 1956 Zazzi-sAZZaZazgyk I NVENTOR 1 BY 1 I ATTORNEYS United States Patent REMOVABLE CLOSURE FOR VENTILATING OPENINGS IN HOUSE FOUNDATIONS Louis Allabaugh, San Francisco, Calif.

Application February 3, 1956, Serial No. 563,302

1 Claim. (CI. 98-29) This invention relates to closure construction, designed for closing the usual screened ventilating openings in the foundations of buildings, when it becomes necessary to close off such openings to prevent cold air from blowing through the ventilating openings and circulating under the floor chilling the floor of such buildings.

An important object of the invention is to provide a closure embodying a plate of this character which may be positioned over the usual screened ventilating opening with such a close fit with the edges of said opening as to exclude cold air around the edges of the closure plate.

Another object of the invention is to provide spring pressed hooks for removably securing the closure plate in position within the opening by drawing the plate into close contact with the screen normally closing the opening.

Other and further objects and advantages of the invention will be hereinafter described and the novel features thereof defined in the appended claim.

Referring to the drawing:

Fig. 1 is a fragmental elevational view illustrating a closure plate, constructed in accordance with the invention, as positioned over the screened opening of a foundation ventilating system.

Fig. 2 is a sectional view taken on line 22 of Fig. 1.

Fig. 3 is an enlarged fragmental sectional view illustrating the construction of the securing hooks that secure the plate of the closure to the screened opening.

Referring to the drawing in detail, a section of a foundation equipped with a ventilating opening to be closed by a plate forming the subject matter of the present invention, is indicated by the reference character 5, the ventilating opening being covered by the wire mesh material indicated at 6, which in the present showing, has its marginal edge embedded in the foundation. However it is to be understood that this screen or wire mesh material may be supplied with a frame so that it may be fitted in the ventilating opening should it be desired to mount the screen in this manner.

The closure forming the subject matter of the present invention embodies a plate 7 which has its marginal edges curved inwardly at 8 and laterally at 9, the plate being of a size to closely fit within the opening with the marginal edges of the plate contacting with the edges or walls of the opening.

The plate 7 is held in position on the wire mesh ma- 2,821,895 Patented Feb. 4, 1958 terial or screen 6 by means of hooks 10, the hooks having cross bars 11 formed on one of the respective ends thereof, providing a finger grip for eifecting operation of said hooks.

The hooked ends 12 are of such construction that they may be extended between the wires of the wire mesh material 6 to secure the hooked ends to the wire mesh material 6 or screen, as better shown by Fig. 3 of the drawing.

A coiled spring indicated by the reference character 13 circles the shank of each hook, the outer ends of the coiled springs contacting the cross bars of the hooks, while the inner ends of the springs rest against the outer surface of the plate 7, thereby biasing the hooks 10 outwardly and causing the hooked ends 12 to securely fasten themselves between the mesh of the wire mesh material or screen 6.

It will of course be understood that the plate 7 is provided with openings 14 arranged adjacent to the corners of the plate 7, through which the shanks of the hooks 10 extend.

From the foregoing it will be seen that due to the construction shown and described, the hooked ends 12 may be threaded between the wires of the mesh of the wire mesh material 6 and released, whereupon the springs 13 of the hooks will tend to bias the hooks outwardly causing them to securely fasten themselves within the wire mesh.

When it is desired to remove the closure, the hooks may be forced inwardly against the tension of the springs 13 releasing the hooked ends 12 from the wire mesh material, allowing the hooks to be slightly rotated and pulled through the mesh releasing the hooks and permitting the closure to be removed.

Because of the construction of the hooks, it will be seen that the hooks are a part of the plate 7 and will be retained on the plate at all times, eliminating any possibility of the hooks becoming disconnected and ac cidentally displaced.

Having thus described the invention, what is claimed is:

A closure for closing a screened ventilating opening, comprising a closure plate, the marginal edges of said closure plate being curved inwardly and laterally, providing spacing flanges adapted to be fitted against a ventilator screen adjacent to the edges thereof, spacing the closure plate from said screen, said plate having openings adjacent the outer edges thereof, and hooks supported through the openings of said plate adapted to be hooked into the mesh of said screen, removably securing said closure to said screen and closing said ventilating opening, said books including a shank, a spring about said shank and a cross bar fixed to the outer end of said shank.
