Bernard Douglas Winser, Brentford, England Application August 8, 1942, Serial No. 454,130 I In Great Britain February 17, 1941 Claims. (Cl. 98-8) This invention relates to ventilators or windows for rooms, vehicles, aircraft, ships cabins and the like.

The invention is particularly applicable to ventilators adapted to be fitted to windows, rooflights, ships scuttles or equivalent, and it can also be applied to the mounting of shields or visors on tanks or other vehiclesused in warfare. For simplicity of description, howevenall such ventilators, windows, shields, etc., will be referred to in the accompanying claims as closure members" or closures, while the closure members and their supporting mechanisms will be referred to as ventilating devices]? Windows are frequently provided with glass closures, which can be hinged about one edge so as to control the flow of air into and from the room. Similarly, the roof-lights of caravans or other vehicles are frequently hinged about one edge for the same purpose. Such an arrangement has the disadvantage that the opening aiforded by the opened closure always faces in one direction, so that while the closure or rooflight may be set correctly when the wind is blowing from one quarter, there may be far too much draught in the room or equivalent, or too little air entering, if the direction of the wind changes. Thus, it is obviously advantageous to be able to present the opening afforded by the ventilating device to the direction from which the wind is blowing, or to shield the opening in that direction, as the case may be.

One object of the present invention is to provide a ventilating device for controlling air flow through an aperture wherein the closure member is supported at each of two opposite sides by a fixed supporting member arranged in or adjacent to the aperture, and by movable mechanism including a mounting on the closure, a link for connecting the said supporting member to the said mounting, joint means for connecting the link to the supporting member and other joint means for connecting the link to the mounting,

. at least one of the joint means being a universal Joint.

In any construction, the ventilating device comprises a closure, a fixed supporting member at each of two opposite sides of the closure arranged in or adjacent to the aperture, and movable mechanism which connects the closure to the supporting member or members and which includes at least one universal joint means.

The above expression fixed supporting member" is used to denote that the support is fixed at such times as the closure is being adjusted.

I Obviously, such supports'may' themselves be adsible. One particularly advantageous application is to the roof-light ota caravan, the usual rooflight being hinged at one edge only and thus quite unsuited to provide proper-ventilation and to prevent unwanted draughts, on account of changes in the wind direction. Other advantageous applications are to the windows or rooflights of motor cars and to the ventilation of rooms having windows which face on to a passage or entry, such as that between two closely adjacent houses.

Several constructional forms of the invention, all applied to ventilating devices, will now be described, by way of example, with reference to the accompanying drawings, in which:

prevent displacement of the closure.

sponding to the open condition shown in Fig. 7. Figs. 8 to 10 are part sections of the outer link and Figs. 11 and 12 are sectional end views, and

Fig. 13 is a view partly in section, of part of a ventilating device, and shows one link of a modification in which the closure is supported at each of two opposite sides by a single link having a universal and slidable connection with the closure.

In the following description, the expression inner links means those links which are nearest to the walls of the opening, and outer links? means those links which are nearest to the Ventilator.

.One embodiment of the invention, as applied to a roof-light of a vehicle, is constructed as follows. Referring to Figs. 1 to 3, the glass-rooflight I, which is hinged along one edge in the usual manner, is formed with a central rectangular opening 2. Midway of each of the longer edges of the opening a bracket 3 is fixed to the roof-light, the two brackets being diametrically opposite to each other. Each bracket is recessed to form two jaws between which the edge of the roof-light bordering the opening is embraced, the bracket being fixed by two screws 4 pulling the two jaws towardseachother. On opposite sides of the brackettwo

inner links

5 and 6 are pivoted at their inner ends on a pin 1 fixed in the bracket, the inner ends of two outer links 8 and 9 being pivoted between the outer ends of the inner links on a pin I extending be-- The outer ends of thetwo links 8 and 9 are of bulbous shape as shown more clearly in Figs. 4 to 4B, so as to form between them the socket portion ll of a ball and socket joint adapted to'embrace the ball part of the said joint. The balls I2 are arranged on the inside of a rectangular pane of glass 13 which forms the closure. Each ball is integral with a shank I4 which is passed through a hole in the closure and projects beyond the external surface of the latter, where it is screw-threaded and provided with a nut l screwed down upon a washer to Disengagement of the ball l2 from the socket formed between the bulbous parts ll is prevented-by rivets l6 preventing lateral separation of thelevers 8 and 9 and passing through tubular distance pieces Thus, at each of two diametrically opposite sides of the opening Zthere is an assembly of a bracket 3,

inner links

5, 6 and outer links 8, 9, and ball and socket joints ll, l2 as described above. Completely surrounding the closure there is a rubber sealing member I8, which is recessed to receive the peripheral edge of the closure and is also formed with a flange l9 which, or part of which, can be pressed closely into contact with the exterior of the roof-light to form a weatherproof seal therewith as shown in Figs. 1 to 1G,

for example. It will thusbe understood that the closure can be adjusted and orientated in many directions so as to prevent the entry of air, or to admit air, to the interior of the vehicle from difierent quarters. By suitably extending or collapsing one or the'other or both sets of

links

5, 6 and 8, 9 andby swivelling the closure by means of the ball joints ll, l2, it can be set to face any desired direction and at any desired inclination. The closure is shown diagrammatically in various adjusted positions-in Fig. 1A to Fig. 1C'by way of illustration, but it will be understood that it can A be made to occupy many other positions by Means, including wing nuts, for example, may

be provided for locking the

links

5, 6 and 8, 9 in their collapsed and extended positions and (or) for locking the swivel joints ll, [2, so as to fix the closure in its adjusted positions. Each set of links may include more than two links and be replaced by pin 38 extending transversely across the two spaced parts of the link 32. A spring 39 is arranged in each socket part 36, with its inner end bearing against the part 3'! and its outer end against a pad 39A interposed between the spring I and a ball-like member 40 having a stem 4| which projects through an elongated slot 42 formed in the outer end of the socket and extending lengthwise of the socket, the stem being connected to an angle bracket 43. The two angle brackets 43 are fixed at diametrically opposite positions to a frame 44 of Z-section, the,

inner flange 45 of which carries a glass closure or window 46, while the outer flange 41 is adapted to form a seal with the outside of the walls or frame (Fig. 5) or any one of the walls or sides of the frame (Figs. 6 and '7) surrounding the opening 34.

As shown in Figs. 8 to .12, the ball member 40 is formed with three

flats

40A, 40B and 400 between its inner and outer ends, the section of the member between the ends thus being triangular. Fig. 8 shows the position of one of the sockets 36 when the closure or window is closed, and it will be seen that the closure is locked in that position by virtue of the ball member 40 being squeezed by the spring 39 between the outer wall of the socket and the pad 39A. Fig. 9 shows how when the socket 36 has been raised, for example, to the position shown on the right of Fig. 6, the stem 4| has moved downwards in the slot 42, the ball member being inclined across the interior of the socket and being held in that position by the pressure of the spring exerted on the ball through the pad 39A. In Fig. 10 and Fig. 11, the socket 36 is shown adjustedintoa vertical position, in which the stem 4| projects through that part of the slot 42 which is parallel to the axis of the socket and is therefore at right angles to said axis, while the pad 39A is held against the apex of the sides 40B and 40C. Fig. 12 shows in full lines the bracket 43 and socket 36 brought into such relative positions that the pad 39A bears against the fiat 490. By such an arrangement, the closure can be resiliently locked in a number of adjusted positions.

in the modified construction shown in Fig. 13, the closure 56 is supported at each of two opposite sides by a single link only, which is similar in construction to the outer link 35 shown in Figs. 5 to 12. The link comprises a tubular socket 5| fixed to a part 52 which is pivotally mounted on a pin 53 fixed in a bracket 54 attached to the wall bordering the aperture 55. A spring 56 bears at its inner end against the part 31 and at its'outer end against a pad interposed between the spring and a ball-like member 58 provided with as many fiats as may be desired for locking purposes. The member 58 has a stem 59 which extends through a slot 60 in the socket and which at its outer end is pivotally connected to a member 6! slidably arranged in a guide 62 fixed to the underside of the closure. The slot 60 is, of course, sufiiciently wide to permit the required inclination of the closure in a plane at'right angles to the plane of the figure.

The closure shown in the drawings is rectangular. It will be appreciated, however, that it may be any other shape, such as square, elliptical, circular and so on. Further, although the invention has been described above with specific ref erence, to closures for ventilating devices, its application to windows, shields, plates and frames and other equivalents of closure members will be readily understandable by those skilled in the art.

It will be understood that the ball member 40 can be provided with more or less than three flats, thus enabling the closure to be locked in a greater or less number of positions.

An obvious mechanical equivalent of the flats on the ball-like member 40 (Figs. 8 to 12) or 58 (Fig. 13) and the spring-pressed pad 39A (Figs. 8 to 12) or 51 (Fig. 13) consists in providing a pinrality of spaced recesses in the ball-like member adapted to be engaged by a pipe or projection on the pad.
