United States Patent HOLLOW BUILDING WALL VENTILATING DEVICE Shepard J. Wilder, Concord, N. H.
Application April 8, 1955, Serial No. 500,086
6 Claims. (Cl. 20-4) This invention relates to means for providing ventilation for the interior of hollow building walls.
It is well known that water vapor frequently gets into a hollow building wall and this vapor becomes condensed when cooled. The resulting water is generally believeda building for the purpose of permitting any vapors which enter into the space of a hollow wall to escape.
Another object is to provide ventilating devices of this type which may be readily applied to the outer part of a building wall by merely driving the devices by means of a hammer or other implement through a part of the wall.
A further object is to provide a device of this kind with a nail or spike which may be used to drive the device through a part of a building wall and which nail or spike, when removed, leaves the device open to establish communication between the interior of the wall and the ambient atmosphere.
Other objects and advantages will be apparent from the following description of some embodiments of the inven tion, and the novel features will be particularly pointed out hereinafter in connection with the appended claims.
In the accompanying drawings:
Fig. 1 is a fragmentary, perspective, sectional view of the outer part of the building wall showing ventilating devices embodying this invention applied thereto.
Fig. 2 is a fragmentary, sectional view of a building wall on an enlarged scale, taken partly on the line 22, Fig. 1.
Fig. 3 is a central, sectional view on a still larger scale of a ventilating device embodying this invention showing the same assembled on a spike.
Fig. 4 is a similar sectional view of the ventilating device when the spike has been withdrawn therefrom.
Fig. 5 is a transverse section thereof on an enlarged scale on line 5-5, Fig. 4.
Ventilating devices of this type are particularly desirable for use in connection with building walls constructed mainly of wood, and Fig. 1 shows by way of example the outer part of a hollow building wall, this outer part including the usual sheathing 6 which may be of wood or other material, and 7 represents the usual outer material of the wall which may be clap boards, wooden or other types of shingles, or the like.
8 represents the inner surface of a building wall which may be of lath and plaster of other material, and which is spaced from the sheathing to form a hollow interior 9 of the wall, Fig. 2, in which water vapors tend to collect and which it is desirable to ventilate.
My improved ventilating devices include small tubes 10 which it is desired to force through the outer layer Z of a building wall. These ventilating devices are of hollow cylindrical or tubular form and preferably the ends, which extend into the hollow wall, are tapered or of frusto conical shape, as shown at 12. These tubes are preferably made of metal such, for example, as aluminum, and may if desired be provided adjacent to their tapered ends with transversely extending holes or openings 14. When these tubes are inserted into a Wall, as shown in Fig. 2, the hollow interior of each tube forms a communication between the space 9 of the wall and the exterior of a building. Air carrying water vapor may pass outwardly through the hollow tube by entering at the tapered end of the tube and through the openings 14, and passing outwardly through the tube to the exterior of the building, or fresh, outside, drier air may pass through the tube in the opposite direction to the interior of the wall.
In order to facilitate the positioning of these ventilating tubes in a building wall I preferably provide a spike or pin having a shank portion 15 formed to extend through the interior of the hollow, tubular ventilating member 10 beyond the tapered end 12. thereof. and terminating beyond this end of the tube in a pointed end 16. This spike is preferably provided with the usual head 17 which may be struck by a hammer or other implement to drive the spike with a ventilating tube thereon into a wall. The spike, however, is preferably provided in spaced relation to the head 17 with a radially, outwardly extending flange or bead 13 which is formed to bear against the outer end of the ventilating tube ll Consequently, when the spike and tube are assembled as shown in Fig. 3, they may be readily driven into the outer part of a building wall, as shown in Fig. 2. After the tube and spike have been driven into a building wall, the spike may readily be removed for use in connection with other ventilating tubes. The tubes should be driven at an upwardly extending inclination so that the inner tapered end of the tube is located at a higher elevation in the interior of a wall than the outer end thereof, so that rain water will not tend to pass through the tube into the interior of the hollow wall. Preferably also the ventilating tubes are driven into the wall closely to the lower edges of the clapboards or shingles, which further opposes the entry of rain into the interior of the wall.
The auxiliary ventilating holes 14 formed in the ventilating tubes 10 are preferably provided with burrs or outwardly projecting parts 2%! for the purpose of opposing the removal of the tube in the reverse direction from a building wall. These projections have the further function of preventing any material of the building wall from entering into the holes 14 and plugging the same, as might happen for example if the ventilating devices driven through asphalt shingles or similar materials.
The ventilating tubes as herein disclosed have the advantage that they can be very easily and quickly inserted into a buildingwall, generally by use only of a hammer. However, if necessary, to prevent splitting of wooden parts of the building wall, holes may be drilled into the building wall before driving the tubes into the same, the holes being smaller, or at least no greater in diameter than the external diameter of the tubes. hese ventilating tubes are of small diameter but provide amply for removal of vapors from the interior of a wall. When the building includes upright frame members between the sheathing and the inner part 8 of the wall, it is of course desirable to apply one or more of these ventilating tubes between each upright frame member. The ventilating tubes being small in diameter, are quite inconspicuous when applied to a building wall so that they do not detract in any way from the appearance of the building.
The use of spikes or pins for driving the ventilating tubes into a building wall has the advantage that the tubes may be made with relatively thin walls and will not be damaged by driving them into a wall for the reason that the shank of the spike or pin holds the tube against deformation during the driving of the same into the wall and also the outer end of the tube is not damaged by receiving the hammer blows indirectly through the flange or bead of the spike.
it will be understood that various changes in the details, materials and arrangements of parts, which have been herein described and illustrated in order to explain the nature of the invention, may be made by those skilled in the art within the principle and scope of the invention as expressed in the appended claims.
