VENTILATOR.
Specification of Letters Patent.
Patented July 9, 1918.
Application filed December 15, 1917. Serial No. 207,635.
I To all whom it may concern:
Be it known that I, ARTHUR J. BRADLEY, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented a new and useful Improvement. in Ventilators, of which the following is a specification.
My invention relates to improvements in ventilators for port holes and the like wherein a plurality of intercalary U-shaped mem bers cooperate to form a series of tortuous channels for the passage of air and to prevent the passage of light and retard the passage of water; and the objects of my invention are First, to provide an improved ventilator for windows, port holes and the like adapted to permitthe. assage of'air'and prevent the passage of lig t;
Second,-to provide an improved ventilator for shipsport holes and the like adapted to permit. a free passage of air and retard a passage of water to prevent the flooding of a compartment or stateroom;
Third, to provide an improved device of the character described adapted to ventilate a stateroom or the like without exposing said room to the danger'of becoming flooded from heavy seas;
Fourth, to provide an improved device of the character described adapted to drain water from the channels to the outer side of the device; and
Fifth, to provide an improved ventilator adapted to permit the passage of air, prevent the passage of light and to retard the passage of water and having means for easily and readily securing said ventilator within an open port hole or the like.
I accomplish these several features by means of the device disclosed in the-drawings forming a part of the present specification wherein like characters of reference the assage of water around the outside of are used todesi'gnate similar parts throughout the said specification and drawings, and in which- Figure 1 is an elevation of the inner side of my improved ventilator;
Fig. 2 is a horizontal sectional view taken on line 2-2 of Fig. 1;
Fig. 3 is an elevation of the outer side of the ventilator; and 1 Fig. 4 is a broken vertical sectional view taken on line 4- -4 of Fig. 3.
Referring to the drawings the numeral 1 is used to designate a suitable circular frame of the'drum type, slightly conical to facilitate insertion into a port hole or the like, not shown.
The frame or drum 1 is provided with equally spaced bifurcated lugs 2 by means of which the said drum may be readily attached and detached from within a port hole or thelike.
I Secured within the drum 1 are a plurality of opposed and vertically disposed intercalary U-shaped members 3 a portion of whose flanges 4 are each oflset an equal distance as at 6 to provide a series of tortuous passages 8 having enlarged chambers 7 adjacent said ofi'set portions 6. The end of each otiset portion 6 of each flange 4 is provided with a lateral flange 9 to reduce the entrance or exit of each enlarged chamber 7, the further purpose of which will hereinafter be more fully described.
Vithin each chamber 7 is mounted a vertically disposed V-shaped member 11 provided to further retard the passage of water through the said chambers 7.
'T he depth or width of the drum 1 is greater than the assembled U-shaped members 3 so that each edge of said drum- 1 extends beyond the said U-shaped members 3 on the inner as Well as the outer side of the ventilator. a y
A draining shield or plate 12 is mounted across the lower inner side of the drum 1 so as to leave an air space between said plate 12 and the inner surfaces of the lower portions of the members 3.
This plate 12 is provided to prevent the passage of water through the lower portions of the tortuous channels 8 into the room or compartment and to facilitate the drainage of'said lower portions of said channels to the outer side of'the ventilator.
- The drum 1 is provided with an annular flange 11 and a suitable gasket 16 to prevent said drum when in position within the port hole.
of a ship may be properly ventilated with out displaying lights while passing through danger zones infested by submarines and other hostile vessels.
During heavy weather a high sea will frequently dash considerable water against the port holes of a ship requiring them to be closed and thereby prevent proper ventilation of the various compartments and state rooms within the range of high waves and the like.
i/Vith the present invention installed within a port hole the passage of air is readily permitted and the passage of light rays prevented by the tortuous passages 8. The said passages 8 will also retard the progress or passage of considerable water as the sea or wave will generally subside before the pressure thereof has forced any water through the entire lengths of the several tortuous passages 8.
Any water cast against the outer side of the ventilator will first enter the outer ends of the tortuous passages or channels 8 and in entering the first series of enlarged chambers 7 will be retarded by the V shaped members 11 which diverge toward the outer side of the ventilator. If the water proceeds beyond the first series of chambers 7 its passage Will be further retarded by the lateral flanges 9 on the offset portions 6 of the flanges 4 of the U-shaped members 3.
Should the water then proceed farther into the channels 8 to the second series of enlarged chambers 7 the V-shaped members 11 therein will still further retard the passage of water.
After the-subsidence of the wave or pressure there from any Water within the channels 8 will naturally fall toward the bottom of lower ends of said channels. As the plate 12, being on the inside of the ventilator, will prevent the water from running into the ,room or compartment, said water will be drained from the lower portion of said channels, such drainage being facilitated by the curvature of the lower half of the drum 1, to the outer side of the ventilator.
It is obvious from the foregoing that I have provided an improved ventilator for port holes and the like adapted to permit the passage of air for ventilating purposes and prevent the passage of light rays which would otherwise render a ship conspicuous, as well as retarding the passage of water through the port hole.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. A ventilator for port holes and the like comprising a plurality of intercalary U- shaped members arranged to provide a series of tortuous channels for the passage of air and to prevent the passage of light and retard the passage of water; and means for securing the intervolved members within a port hole or the like.
2. A ventilator for port holes and the like comprising a plurality of opposed and vertically disposed U-shaped members arranged to form a series of tortuous vertically disposed channels for the passage of air and to prevent the passage of light and to retard the passage of water; means for securing the members Within a port hole or the like; and means for draining the channels to the outer side of said'members.
3. A ventilator for port holes and the like comprising a plurality of opposed and vertically disposed U-shaped members arranged to form a series of vertically disposed channels for the passage of air and to prevent the passage of light and to retard the passage of water; a circular drum inclosing the U-shaped members; and a shield secured within the lower inner side of the drum and spaced apart from the U-shaped members to permit the passage of air and drain the channels to the outer side of the ventilator.
4. A ventilator for port holes and the like comprising a plurality of opposed and vertically disposed U-shapedmembers arranged to form a series of vertically disposed channels for the passage of air and to prevent the passage of light andto retard the passage of water; a circular drum inclosing the U- shaped members; and a shield secured within the lower inner side of the drum and spaced apart from the U-shaped members to permit the passage of air and drain the channels to the outer side of the ventilator; and means for securing the drum within a port hole or the like. a; 5. A ventilator for port holes and the like comprising a plurality of opposed and vertically disposed intercalary U-shaped members having flanges provided with inwardly offset portions, to form a series of verticallydisposed tortuous channels, said ofi'set portions forming enlarged vertically disposed chambers within the channels, to permit the passage of air and prevent the passage of light and to retard the passage of water; vertically disposed V shaped members mounted within the enlarged chambers and diverging toward the outer side of the ventilator to obstruct the passage of water through the tortuous channels; means for draining the lower portions of the channels to the outer side of the ventilator; and means for securing the ventilation within a port hole or the like.
6. A ventilator for port holes and the like comprising a plurality of opposed and vertically disposed intercalary U-shaped members having flanges provided with inwardly offset portions, to form a series of vertically disposed tortuous channels, said oifset portions forming enlarged chambers Within the tortuous channels, to permit the passage of air and prevent the passage of light and to retard the passage of water; vertically disposed V-shaped members arranged Within the enlarged chambers and diverging toward the outer side of the ventilator to fursurrounding the U-shnped members; and ther obstruct the passage of water; out means for securing the frame within a port wardly extending flanges on the ends of hole of the like. 10 the offset portions to further obstruct the In witness whereof I hereunto set my sig- 5 passage of water; means for drainin the nature.
