Patented Muay 29, 1934 UNITED STATES ADJUSTABLE LoUvEn wnvDow John Waddell, Dubbo, and Frederick Alexander Huet, Warren, Australia Application February f1, 1933, Serial No. 655,650 4 Claims. (Cl. 18S-62) adapted for fitting to any appropriate framed opening as a window-ventilator, either in substitution for or as part of a sliding sash. Owing to its compactness, the absence of any projectl ing parts and any loose elements, and the provision of anti-rattling means, the construction is particularly adapted for installation in a road or rail vehicle of closed type, as part of, or constituting, a vertically sliding window raised and lowered by known means, or as constituting a Windscreen.
A feature of the invention is that when the louvers are clos'ed or opened vision therethrough is practically unobstructed.
To fully explain the invention reference is now made to the accompanying drawing, which depicts a practical embodiment of the invention.
In the drawing,
Fig. 1 is an outside perspective view of a complete louver window according to this invention,
Fig. 2 is a vertical cross-sectional elevation thereof with the slats closed, and also showing (in dotted lines) the position of the vslats when open.
Fig. 3 is a fragmentary perspective view of one end of one of the glass slats showing how it is held in a channel-shaped metal clip, the web of the channel being omitted to show clearly details of construction hereinafter described.
Fig. 4 is a cross-sectional plan on line 4, 4 of Fig. 2;
Fig. 5 is a cross-sectional plan 'on line 5, 5 of Fig. 2; 6 is a cross-sectional plan on line 6, 6 of Fig. 2;
Fig. 7 is an elevation of the parts shown in Fig. 6; and
Fig. 8 is a perspective view showing the appliand each clip is formed with an eye 13 constituting a hinge element engaging a. hinge pin 14 secured in the frame 10 (see Fig. 4).
The upper and lower edges of the slats (except the upper edge of the top slat and the lower edge 30 of the bottom one) are shaped or curved as shown, the top edge of a slat having a cymareversa profile as at 15 (Fig. 3) and the bottom edge a cyma-recta prole as at 16.l At each end of each slat the lower edge is checked out for a width equal to the width of the metal clip 12 and to a depth equal to the thickness of the metal of the clip, and the extreme outer end of each clip is turned under as shown at 17 (Fig. '3). This construction ensures security of 70 the slats in the clips, and they are further secured by means of screws such as.18 (Fig. 3) and/or cement.
The particular formation or shape of the edges Aof the slats is preferred for the reason that it is easier to make thanv a square rebate and the vcurved formation is stronger than one of angular Fig. 2, than would be the case were the contacting surfaces planar.
The means for adjusting the slats from closed to open position and vice-versa are preferably provided in duplicate; one set atl each side of the frame, but as each set is a replica of the other it will be sufficient for the purposes of this speciiication to describe one set only.
Such means include a plurality'of arcuate radius arms 19, 19 each of which is secured at one 90 end to a clip 12 of oneof 'theslats, is passed through aA guiding aperture in the iiange 10 of one of the side frame members and is terminally pivoted to a vertical operating bar 20 lying parallel with the frame member and movable vertically. The bar 20 is urged in an upward direction by a spring 21 and each radius arm 419 is urged in a direction to close its associated slat by a coil spring 22 fitted on a stud 23; one radial end of spring 22 engaging a stamped eye 25 in the 100 radius arm and the other anchored to the frame, as by engaging a hole therein as at 24 (Fig. 2).
Studs 23 also serve to secure an angular cover plate 26 enclosing the operating mechanism.
The bar 20 is actuated by means of lever 105- mechanism comprising a hand lever 27 disposed on the outside of the cover plate 26, secured at one end to a rotatable stud 28 mounted in the frame and cover plate, and from which extends a second lever 29 (Fig. 6) which is terminally 110 formed with a slotted eye engaging a pintle 30 on the bar 20. The exposed hand-lever 2'7 at its free end is provided with a spring backed detent pin 31 adapted to engage any one of a series of holes 32 in the cover plate 26 (Fig. '1).
'I'he parts being in the relative positions shown in Fig. 2 (full lines) and Fig. '7, to open the slats the hand-lever 27 is pulled downwardly and this movement is communicated by lever 29 to operating bar 20 which also moves downwardly and sideways towards the slats. The sideways movement is permitted by the slotted eye in lever 29. The downward movement of bar 20 effects consequential movement of the radius arms 19 which moving through the flange 10' open the slats 11 to the desired extent by turning them about the pins 14, and when this is attained the spring detent 31 is permitted to engage in one of the holes 32 thus retaining the slats in adjusted position.
It will be observed that the opening of the slats is effected against the tension of springs 21 and 22, and this permanent tension prevents the parts from rattling.
It will also be observed that there are no metal edges on the slats and that for this reason there is no solid obstruction to vision even when the slats are closed.
It will further be observed that all the parts, including the slats when closed, lie within the connes of the frame, and that the latter may be fitted. as a sliding sash as, for example, in the door 33 of a motor vehicle as shown in Fig. 8.
We claim,
1. An adjustable louver window comprising a plurality of glass slats hingedly mounted in a frame and Slat-adjusting means comprising radius rods connected respectively to said slats and to a common operating bar, characterized in that the frame is of T section providing an internal flange or web serving as guiding means for the radius arms which pass therethrough and against which the slats abut when closed.
2. An adjustable louver window comprising, in combination, a frame having parallel vertical side members of T section providing internal flanges or webs, a plurality of glass slats in horizontal parallel arrangement having their 1ongitudinal edges oppositely rebated to form rabbeted joints when the slats are in closed planar position, metal clips of channel section secured on the ends of each of said slats and hinged at their upper ends to the frame, curved radius arms connected respectively at one end to said clips and passing through guide slots in the flange or web of one of the side frame members, an operating bar located adjacent to and parallel with that frame member and movable vertically, means securing the ends of the radius arms respectively to said operating bar, a removable hollow cover fltting over said operating bar and adjacent parts of the radius arms and secured to the frame member, anti-rattling springs housed Within the cover, a spring, also housed within the cover, urging the operating bar in a direction to close the slats, and means for moving the operating bar in either direction, said means comprising a lever secured at one end to a rotatable stud having bearing in the frame and cover and at its other end engaging the operating bar, a hand-lever secured on said 'stud which projects through the cover, and disposed on the outside of the cover, and detent means for holding said hand-lever in adjusted position.
3. An adjustable louver window comprising, incombination, a rectangular frame having an internal flange disposed in a plane parallel with the plane of said frame, a plurality of glass slats in parallel horizontal arrangement on one side of said flange, the contiguous edges of adjoining slats being oppositely rebated to form rabbeted joints when the slats are in closed planar position, metal clips of channel section tted on the ends respectively of each of said slats, the upper ends of said clips being formed as hinge elements engaging with complementary hinge elements secured to the frame and so disposed that said clips abut against said flange when the slats are closed, curved radius arms having sliding engagement respectively with guide slots in said flange, each of said radius arms being connected at one end to one of said clips, a vertically and laterally movable operating bar located on that side of the flange remote from the slats, means,
connecting the other ends of said radius arms to said bar, means for moving the bar up and down to close and `open the slats, and means for retaining the bar in adjusted position.
4. An adjustable louver window as claimed in the preceding claim, characterized in that all the operative and movable parts, when the slats are closed, lie within the confines of the frame.
