Description
May 20, 1941. a s L oY VENTILATING DEVICE Filed April 21, 1939 F IGJ I Bun'r S Lov INVENTOR r1 AW WW ATTORNEYS FIG BY/o
Patented May 20, 1941 5 Claims.
This relates to ventilating equipment and more particularly to ventilators adapted to pick up and convey fresh air to the interiors of ships, houses or other building structures.
The principal object of the invention is the provision of a simple down-draft ventilator having improved means for preventing the ingress of water to the pipe or conduit to which it is connected.
In accordance with the invention, the air which may or may not contain water in suspension enters a funnel-shaped collecting member or shell where it passes rearwardly around one or more baflle members. In striking the baifies water is separated from the air and runs downwardly and outwardly away from the intake pipe or conduit. The air after reaching the rear interior portion of the shell is deflected into the intake conduit and additional bafiies are provided for separating water which may still remain in the air.
For a better description of the invention reference may be had to the accompanying drawing in which Figure 1 is a vertical front elevation of apparatus embodying one form of the invention;
Figure 2 is a sectional plan view on the line 22 of Figure 1 looking upwardly in the direction of the arrows;
Figure 3 is a vertical front elevation of an apparatus embodying another form of the invention;
Figure 4 is a sectional plan view taken on the line 4-4 of Figure 3;
Figure 5 is a sectional side elevation on the line 5-5 of Figure 3; while Figure 6 is a view similar to Figure 4 but showing a slightly different arrangement.
Referring to Figures 1 and 2 of the drawing, an air collecting or intake member ID is mounted on a section of pipe or conduit l2 which in turn is rotatably supported in a suitable bearing plate l4 secured to a support such as a deck or floor Hi. If desired, a conduit I8 may be connected to the plate 14 so as to conduct the air to any desired point in the interior of a ship or other structure. The intake member In is formed of flat upper and lower walls 20 and 22 respectively and a curved side wall. 23 having flaring front edges. The intake member is attached in any suitable manner to the upper end of the pipe l2 which terminates a short distance above the bottom wall 22. Attached to the upper end of the pipe l2 and extending upwardly to the top wall 20 is baffle member 24 which may be a short section of pipe similar to E2 but with the rear portion cut out to form a side opening as shown at 26 in Figure 2. A pair of flanges 28 are attached to the vertical edges of the member 24 and extend throughout the length of that member. A curved bafile member 33 is attached along its edges to the inside surface of the rear portion in the side wall 23 and is curved as is shown in Figure 2 so that a center edge 34 will project into or toward the opening 26.
The air which may contain entrained water will enter the flared side of the intake member Ill and will pass to the rear around the baffle 24 where it will be deflected by the curved plates 30 through the opening 26 into the interior of the member 24 from where it will pass downwardly through the conduits I2 and iii. The air on striking the baffle Z l, the flanges 23 and the curved plates 3%! will deposit water on these surfaces, and the water will flow downwardly and out of the intake member Ill, either at its lower front edge or through suitable openings or drain tubes 32 extending downwardly and outwardly through the lower wall 22.
If desired, one or more handles 35 may be attached to the intake member or to the conduit I 2 to aid when it is desired to turn the ventilator into the wind. It will be noted that comparatively few baiiles or other obstructions are located in the path of the air but it has been found that with this arrangementmost, if not all, of the water carried by the air will be separated out and drained off before the air enters the conduit l2.
Figures 3, l and 5 disclose a device similar in many respects to that previously described. A curved funnel-shaped intake member 36 is attached to the upper end of a downflow pipe or neck 38 corresponding to the pipe l2 of Figure l. The member 38 is provided with a flared forward edge 39 which may be circular, oval or of any other desired shape and the shape of the member 36 is such as to direct incoming air downwardly into the neck 33. A partition 48 substantially annular in shape is secured around its outer edge to the lower portion of the intake member 36 and slopes slightly upwardly toward a center opening 4| where it is provided with a vertically extending rim or flange 42. A trough 43 is thereby formed for collecting water running down the inside surface of the shell 38.
Extending upwardly from the front of the rim 42 is a bafile member 44 which diifers from the bafile member 24 of Figure 2 in that it does not extend as far rearwardly and which can be considered as forming an upward extension of the neck 38. The vertical edges of the member 44 are provided with forwardly extending flanges 46. A pair of vertical bafile plates 43 are mounted preferably as shown in Figure 4 so as to obstruct the direct flow of the air but to allow spaces at either side such as are shown at 50 and 52 through which the air can pass rearwardly and'then downwardly through the opening 4| formed in the rim 42 and into the conduit 38. A second annular partition 53 is secured to the inner upper surface of the conduit 38 and a rim 54 projects upwardly from the partition 53 forming a trough 55 and leaving a central opening 51 through which the air passes in its downward flow. With this arrangement it has been found that substantially all of the water carried by the air will be deposited on the baffles 44 and 48 and the flanges 46 and will flow down these surfaces to troughs 43 and 55 and outwardly through suitable openings 56 and 58.
, Although the baffle plates 48 are shown in Figures 3, 4 and as being fixed in position, these plates can be mounted on pivots 60 as shown in Figure 6 and suitable knobs or handles 62 provided outside of the intake member 36 for rotating the baffie plates 48a. In this manner the plates 48a can be positioned so as to control the amount of air entering the ventilator.
Obviously many modifications and variations of the invention as above set forth may be made without departing from the spirit and scope thereof, and therefore only such limitations should be imposed as are indicated by the appended claims.
