Jamal? File d Nov. 4, 1954 United States Patent VENTILATED BLOCK WALL Marion D. Murphy, West Palm Beach, Fla.

Application November 4, 1954, Serial No. 466,793 1 Claim. (Cl. 72-127) This invention relates to improvements in ventilators for walls provided with air spaces, particularly concrete cell block walls, and method of venting said walls.

Prior art practices have provided air passages in walls, but have been moisture trapping; and, the prior art devices were expensive, requiring many parts, and failed to provide proper inter-cell circulation of air.

An object of this invention is to provide ventilators for 'walls of the type described, which may be easily inserted in face-bed mortar joint during construction to provide vertical and perimeter ventilation.

Another object of this invention is to provide a positive draft ventilation through all the cells of a concrete cell block wall.

A further object of this invention is to provide a device of the class described employing a minimum of parts, which may be fabricated by unskilled labor.

A still further object of this invention is to provide a ventilator of the class described which will be simple and inexpensive in construction, easily and conveniently installed, and efficient and durable in use.

The foregoing and other objects and advantages of this invention will be more clearly understood from reading the following specification in conjunction with the drawings forming a part thereof, wherein:

Fig. 1 is a perspective view of a corner joinder of concrete cell block walls, parts removed and broken away, showing the invention in use;

Fig. 2 is a plan view of a first stage corner construction showing the air intake ventilator elements in position on the first row of cell blocks;

Fig. 3 is vertical cross-sectional view of a cell block wall employing the ventilators of this invention;

Fig. 4 is a longitudinal cross-sectional view of the ventilator, taken on line 4-4 of Fig. 2, showing insect barrier and moisture-proof air passage;

Fig. 5 is transverse cross-sectional view of the insect barrier in the moisture-proof air passage, taken along line 5-5 of Fig. 4;

Fig. 6 is a perspective view of the intake ventilator with air circulation extension member;

Fig. 7 is a perspective view of the exhaust ventilator; and

Fig. 8 is a vertical cross-sectional view of the air intake member in a wall, taken along line 88 of Fig. 2.

Referring to the drawings wherein like members are given the same reference numeral, the numeral 1 designates conventional footings upon which conventional concrete cell blocks 2 are laid in course; the upper course being capped by a perimeter or limited beam 3, usually poured reinforced concerete, having anchor bolts 4 for rafter beams 5.

Air intake and exhaust ventilators, 7 and 8 respectively, are positioned in the wall as shown. They are the same in general design, differing in width; the intake ventilator 7 covers a position of the block cell, to permit air circulation, and the exhaust ventilator 8 covers the cell to prevent further circulation.

1 2,868,010 Patented Jan. 13, 1959 The intake ventilator 7, placed preferably over the first row of cell blocks, has an elongated channel-shaped body 10, and perpendicular thereto an outwardly extending channel-shaped projection 11 having the outer end 12 thereof bend downward at an angle, preferably 30 to 60. The channel-shaped body 10 and projection 11 are in the same plane, and may be formed by molding, stamping or drawing according to conventional practices. The height or thickness of the channel-shaped member, however, is less than the thickness of a face-bed mortar joint, so that no weight is placed upon the ventilator member, the Weight being distributed through the mortar joint.

To provide complete perimeter ventilation, the member having intake projections 11 preferably may be positioned to place an intake projection every 36 to 48 inches, with a channel-shaped connector 14 joining the members to provide a continuous air passage. These connectors 14 may abut the main body 10 of the air intake member; or preferably, as illustrated, the connector 14 telescopes over the body member 10.

A novel and efiicient insect barrier or guard is provided for the air intake and exhaust projections 11 and 11, respectively, providing a press-fit, hand tight, saddle bracket 16, having the legs 17 thereof abutting the downward flanges 18 of the projections 11 and 11', to anchor mesh or screen material 19 across the external opening of the projection member.

The intake ventilator members 7 may be used beneath the lintel beam 3, or U-blocks in a conventional manner, for air exhaust ventilator member 8, with the lintel beam or U-block capping the cells of the upper course of blocks. Experience has taught, however, that it is better to use a similar shaped channel member differing from the intake member 7 in width to substantially cover the cells of the'block. Accordingly the elements of the exhaust ventilator are designated channel-shaped body 10; outwardly extending channel-shaped projection 11 having a downwardly turned outer end 12; and channelshaped connectors 14'.

The body member 10 and 10, and connectors 14 and 14' are mitered to provide corner joinders, as illustrated in Figs.-l and 2, as indicated at 20 and 20 respectively.

The parts of the devices of this invention may be fabricated in any conventional manner of suitable rigid material. It is preferred, however, to stamp the parts from sheet aluminum.

In installation, the intake members 7 with connectors 14 are positioned over the first course of blocks, as illustrated in Figs. 1 and 2, with the channel portion facing down. The second course of blocks is then placed, using a face-bed mortar joint, as is the conventional practice. The mortar joint is thicker than the channel-shaped intake member. On the final course of blocks the exhaust members 8 and connectors 14' are positioned and the perimeter beam 3 poured.

In use, air enters the intake projections 12, see Fig. 3, is carried upward through the cells-and around the perimeter by the connectors 14, and exhausts through exhaust projections 12 having perimeter communication through the connectors 14.

By this invention there is provided an economical means for effecting positive draft through all the cells of a wall, resulting in a dry interior and cooler construction.

The invention has been described in detail, but it is understood that the invention is not so limited; changes can be made therein without departing from the spirit and scope of the invention, as defined in the appended claim.

Having thus described the invention, what is claimed 18:

A ventilated Wall comprising a plurality of courses of vertically cored 'ce'mentitious blocks'havirrg 'mortarjoints' between said courses, a lintel beam secured to the top course of said blocks, and a pair of peripherally positioned ventilating devices positioned Within the said nrortar joints, one of said devices comprising a plurality of space unrestricted channel-shaped members having an outwardly extending channel-shaped projection on each of said members communicating with the atmosphere and the core of said blocks over which positioned, channelshaped connectors forming continuous pheripheral air passages with said members by telescopingly engaging said members, said channel-shaped members and connectors being peripherally positioned over the vertical cores in a course of said blocks near the bottom of said wall, the second set of said devices peripherally positioned in a mortar bed between the top course of said blocks and said lintel beam of sai'dwall, and said channel-shaped 4 members and connectors having a thickness less than the thickness of'tlrem'ortai-"bedin 'wh'tc'hpositioned'.
