The present invention relates to ventilators.

Known types of ventilators commonly employed under extreme weather conditions are defective to the extent that they do not adequately provide against flooding or leakage of water through or around the ventilator in driving rain or sea and are not readily adjustable to accommodate weather changes. For some purposes, as for ventilating small craft, available devices are excessively costly, inflexible in use and involve undue trouble and expense in installation. Also, they are unnecessarily complex and difiicult to maintain in working condition.

An object of the present invention has been to provide a directionally adjustable ventilating device of relatively few parts which can be made to advantage from rugged but relatively lightweight material, such as butyrate, linear polyethylene or the like, and which is so constructed that it can be securely mounted in operative position on a boat deck, or the like, and yet be freely adjustable to maintain effective ventilation without flooding or water leakage under extreme wind, sea and rain conditions and regardless of wind or weather direction. It has also been an object of my invention to provide a ventilator of which the component parts can .be made inexpensively of suitable plastic, can be readily assembled and can be securely mounted in any desired operative position with comparative ease. Other objects and beneficial aspects of this invention will be apparent from the description and the accompanying drawings.

An embodiment of my invention comprises in general a base and lower baffle member adapted to be mounted on a deck or the like and having a sleeve extending through a hole in said deck, a frame having a generally cylindrical outer wall portion and an inner wall portion coaxial therewith and spaced inwardly from and connected to the outer wall by a web interposed between said walls and provided with drain openings, said inner wall forming an air duct open at its inlet and outlet ends and said frame being rotatably mounted on and in telescoping connection with portions of said base. A housing having perforations extending through a lateral wall portion is mounted co-axially on and in position to substantially enclose the frame and is freely rotatable therewith to different angular positions of adjustment. A sec- 0nd or upper bathe is operatively mounted in the housing between said perforations in its wall and the air inlet end of the air duct of the frame and is accessible through the air outlet end of said air duct for hand manipulation to turn the housing and said frame about their common axis and the axis of said duct. Said component parts are advantageously made of butyrate, linear polyethylene, or material having equivalent physical properties.

An embodiment of my invention is illustrated in the drawings accompanying this specification and wherein:

FIGURE 1 is a front elevation of a ventilator, as mounted on a deck, or the like, shown in section;

FIGURE 2, a fragmentary top plan view, with parts broken away, showing portions of the frame and of the upper bafiie member mounted thereon in effective waterdeilecting position between said frame and perforations in the housing as seen in FIGURE 3;

FIGURE 3, a fragmentary view in approximately central vertical section on the line 33 of FIGURE 1;

IGURE 4, a fragmentary view in vertical section on the line -4 of FIGURE 2, showing the position of laterally positioned depending legs of the baffle member in relation to the frame and in water deflecting relation to 2 perforations at the ends of the series of perforations in the transversely disposed wall portion of the housing, as seen in FIGURES l and 3;

FIGURE 5, a fragmentary view in vertical section on the line 5-5 of FIGURE 4;

FIGURE 6, a bottom plan view showing structural features of the base including a lower bathe in the form of a peripheral flange extending from a central sleeve;

FIGURE 7, a fragmentary view in vertical section on the line 77 of FIGURE 6, showing the base mounted on a deck, or the like, with its central sleeve extending through a hole therein; and

FIGURE 8 is a fragmentary view in vertical section on the line --8 of FIGURE 6 showing a bedding or sealing compound filler in the grooves formed between ribs of the base which, when mounted as in FIGURE6, have their edges closely engaging portions of the deck surface surrounding the opening in the deck.

Referring to said drawings, an embodiment of my invention includes, as seen in FIG. 3, an integrally formed base bearing member or mounting plate A preferably of a suitable plastic such as polystyrene, butyrate or the like having a sleeve It) which fits into a hole 11 in a deck or wall 12 and has a peripheral flange 13 which provides a lower bathe integral and coaxial with said sleeve and provided at its underside with radially spaced downwardly extending concentric ribs 14 and 15 between which are spaces or grooves for receiving a filler 16 of sealing or bedding compound or other suitable substance. Said flange is beveled at its peripheral edge 13a to more effectively deflect water which washes in along the deck under the outer edge or skirt of the ventilator housing. Base A is secured to a portion of deck 12 surrounding hole 11 by screws 17 applied through holes I8, FIGURE 6, in said flange I3. As seen in FIGURE 7, the upper end portions of the shanks of said screws pass through and are in efi'ect sealed in the filler mass 16 when the base is mounted in place on deck 12. Also when the base is so mounted, ribs I4, 15 and the filler mass 16 between them press closely against the outer deck surface and thus prevent leakage of water from outside into the space between sleeve It and hole 11.

As seen in FIGS. 6 and 7, sleeve It) is formed with a narrow annular beveled flange 19 projecting inwardly from its inner surface and with bosses extending inwardly in position to provide angularly spaced flat bearing faces 122 for a purpose to be described.

A ventilator according to the present invention also includes an integrally formed frame or spider indicated generally at B which provides a centrally positioned generally cylindrical air duct with an air inlet end 2% at the upper side of deck 12 and flange 13, as viewed in FIG- UPE 3, and an air outlet end 21 extending through said sleeve It and open at the underside of deck 12. Said outlet end 21 of said air duct engages and is freely rotatable on the bearing surfaces 19a of sleeve 10 to provide effective guiding and retaining means for the frame B with minimum friction between said air duct portion thereof and said sleeve 10.

Frame B includes a peripheral annular outer wall 22 radially spaced from said inner end 29 of the duct and also a depending annular rib 23 spaced outwardly from an intermediate portion of said duct and forming therewith, in effect, an annular groove, the under face of said rib 23 when the parts are assembled being adapted to ride on opposed portions of the upper face of flange 13. As seen in FIG. 3 said annular rib 23 overlaps or telescopes with the upper end 11a of sleeve II which fits into said annular groove to form a snug jo' t between said base A and frace B but permitting free turning of said frame in relation to the base. A web having angularly spaced radial arms 24- connects outer wail 22 to the inner end 20 3 of said duct and provides water discharging ports 25 between said arms and between said outer wallZZ and said rib 23:. Said arms are provided with longitudinally extending ribs .26 which serve both to strengthen the fume structure md to support a baffle in a manner to be described.

As seen in FIG. 3, arms 2'4 and thus ports 25 of frame B are spaced vertically above deflector fiange 13 of the bearing A thus providing a guiding path for water discharging through said ports. And the peripheral portion of said flange 13 in addition to serving as a lower bafile against flooding from :the deck is also positioned to facililate the discharge of water outwardly or :away from the joint between rib 23 and the opposed top surface of flange 13 and from around screws 17 toward said deck.

The frame or integral pant B is preferably made of suitable flexible plastic, as polystyrene, butyrate or the like, provided with angularly spaced wedge-shaped lugs 27 extending radially outwardly from an outlet end portion of the air duct. Said lugs are so positioned and dimensioned that when the air duct is pushed downwardly through sleeve and past the beveled face of flange 19 to the position shown in FIG. 3, the duct well being sumciently resilient will yield inwardly to allow the lugs to pass said he eled flange to and through the outlet end of the duct. Upon reaching end position, said lugs snap outwardly to interlock with said flange 19 and the lower edge of sleeve Thus, said parts are retained against accidental disengagement wlule frame B remains free to rotate in relatien to base A.

An upper baffle, as C, also of suitable plastic material includes a deflector plate 23 advantageously of domed crosssectional contour, provided at its under or concave side with a finger-piece 29. Legs extending downwardly from the peripheral edge of deflector 2S and integual therewith are notched at 31 to straddle the ridges of ribs 26 of frame B. Said ribs are provided with abutments 32 which are wider than said notches 31 and thus, when the parts are assembled, afford positive stops to retain said battle with its deflector portion in substantially coaxial relation to the air duct and so that its outer peripheral edge extends radially beyond the air inlet end 29 of said air duct and spaced therefrom vertically to permit unobstructed passage of air around said edge into said duct.

The parts B and C heretofore described are permanently assembled with a housing, as D, to form a unit assembly, FIGURES l 3. Said housing is preferably in the form of a plastic, as butyrate, shell of generally hemispherical or dome shape interrupted by a perforated transverse lateral wall portion consisting in part of bars 34 and arranged at one side of and at an angle to the shell axis and at an angle to a relatively flat top wall portion 35. Said laterzd wall is provided with perforations in the form of approximately vertical slits 33 separated by said bars 3 It is contemplated that the aggregate opening area of slits 33 will be less than that of the water discharge ports 25 in frame B, FIGURE 2, so that, when the ventilator ships water, the incoming volume will always be less than the drainage or discharge capacity of said ports 25 and thereby avoid flooding into the entry end 21} of the air duct of frame B. As seen in FIG. 3, the bottom ends of bars 3 are arranged substantially in an are or obtuse angle arching forwardly so that the bars are in effect disposed in two planes acutely inclined to top wall 35 and at an angle to each other. The arrangement here described provides inclined surfaces for deflecting Water away from the slits 33 which afford adequate air passages while said bars 34 effectively intercept and deflect foreign bodies, insects and the like away from said slits.

As seen in FlGURES 3 and 5, the flared skirt portion of housing D is formed with an inwardly exposed annular shoulder 36 which provides a seat adapted to engage the upper edge of outer wall 22 of frame B when housing D 4 l is perman ntly assembled with said frame. In the form shown, the outer cylindrical surface of outer wall 22 is adhesively or otherwise eifectively secured to the opposed annular inner surface of said housing. Thus, the parts B, C and D are securely and permanently fixed in a unit assembly which can be supplied as such along with the initially separate part A.

As seen in the duawings, upper baffle C is permanently secured on fnarne B with two of its four legs so engaged with ribs as that the diametrically opposed laterally arranged legs 38, for example, FlG RE 4, are positioned in water deflecting relation to the relatively short slits 33a at the ends of the series of slits 33. To this extent said two legs supplement the water deflecting function of the main deflector 23 of batlle C.

When mounted on the deck or" a boat, for example, the parts above described are assembled as shown in FIG. 3, with the sleeve lo of base A secured in hole 11 of deck 2; with frame B mounted to rotate freely on base A; with baffle C secured in water-deflecting position on frame B; and with housing D secured to me B and rotatable therew: to different oserating pos ions. A duct cover E has a nmge 3'7 which fits snugly into the air discharge end 21 of the air duct to close said duct when the ventilator is not in use.

In operation, with the cover E removed from the inner end of the duct, when rain or sea and air drive through slits 33, the water strikes deflector 2-3 and/ or the laterally disposed legs 3% and pours past peripheral edge portions of the deflector 28 toward and through the ports 2.5, some of it striking peripheral portions of flange 13 of base A and naming off to t .e deck 12 through the annular gap between said flange edge and the skirt edge of housing D. Or, when rain or sea drives against the skirt of housing D, part of the water may be deflected by the flared edge portion thereof; and the beveled edge l3a of flange 13 tends to deflect waterfront the space between said edge and the skirt portion of said housing D.

If conditions so require, housing D along with frame B and baffle C may be rotated freely by hand around their common axis and in relation to base A by reaching through the m'r duct, gripping finger piece 29 of the b aille and turning the same to 1 uch extent and in such direction as may be desired.
