3 Claims. (Cl. 20-62) This invention relates to jalousies of the type comprising a plurality of louvres mounted to swing on horizontal pivots from open to closed position in a common and well known way. The device of the invention is adapted for use in either windows or doors but for the sake of brevity it will be referred to as a window. A primary object of the invention is to provide a device of the character indicated comprising a plurality of louvres having actuating means at each end thereof, said actuating means at both ends being operable by a single hand operated element such as a crank, knob or the like and wherein the throw of each louvre is independently adjustable with respect to the actuating means. Thus each louvre is made independently adjustable with respect to its adjacent louvre so that an accurate glass to glass contact may be had at every point throughout the length of the louvre.

A further object of the invention is to provide such interengaging parts between the carrying elements of the several louvres with respect to each other and also between the said carrying elements and the window frame proper, as to produce a structure that will be completely Weather and waterproof even under driving rains and high winds.

The structure by which these objects are accomplished will be best understood by reference to the accompanying drawings, wherein:

' Fig. 1 is a front elevation of a window constructed in accordance with the invention,

Fig. 2 is a fragmentary horizontal sectional view on line 2--2 of Fig. l, with the upper louvre omitted and the middle louvre moved to partly open position,

Fig. 3 is a face view of one of the glass receiving carriers of the louvres,

Fig. 4 is a sectional view on line 44 of Fig. 3,

Fig. 5 is an inverted view of the lower end portion of the carrier of Fig. 3,

Fig. 6 is a vertical sectional view through the top of the window frame on line 6-6 of Fig. 1,

Fig. 7 is a transverse sectional view through the sill member of the window frame on line 77 of Fig. 8, and

Fig. 8 is a horizontal sectional view on line 8--8 of Fig. 7.

The frame of the window may be made of any suitable, light weight, metal such as aluminum, magnesium or otherwise, and comprises a cap 5, a bottom or sill member 6 and vertical sides 7. The cross sectional shape of the sides 7 is shown in Figs. 2 and 8 and the shape there shown extends throughout the height of the sides 7. These sides comprise the front and

rear flanges

8 and 9 which are connected by the webs 10, inwardly directed vertical webs 11 and inwardly directed L-shaped runs 12. The spaces 13 between rear flanges 9 and webs 11 constitute guideways in which vertically movable actuator bars 14 are mounted. The manual actuation of a single operating element serves to impart simultaneous move ment to both bars 14. The operating element employed is of'a well known and conventional type and is shown in Fig. 7. In these elements the rotation of a crank handle C imparts up and down movement to the outer end portion of a crank 15. A link 17 connects said crank to a pivot screw 18, which screw is carried by one of the bars 14. A link 19 is pivoted at its upper end on a screw 18 and at its lower end has pivotal engagement at 20 with a crank 21. This crank is carried by one end of a torque bar 22, which extends across the window just above and at the rear side of the sill. The movement of the actuator bar 14 adjacent the crank 15, is transmitted to its companion bar at the opposite side of the window through the torque bar, said bar having a like crank 21 for engagement with its corresponding bar 14, through a link 19, in the same way that the crank 21 is engaged with its actuator bar 14. The ends of the torque rod are journaled in blocks 24 that are secured in the lower ends of the guideways 13 by screws 25.

In the window illustrated only three louvers are shown. However, it will be understood that the louvres will be varied in number in proportion to thesizeand height of the opening that is to be protected. Each louvre comprises a transparent pane of glass and a pair of pane or louvre carriers, said carriers receiving and supporting the ends of the panes and serving to mount the panes for vertical tipping in the frame. The term glass is used in a generic sense. Glass is usually employed in jalousie windows but plastics are now being'used and the invention contemplates the use of any suitable material in lieu of glass.

Each louvre carrier comprises an outer run 26 and an inner run 27, these being rigidly affixed to each other,

by brazing, spot welding or otherwise. The inner runs 27 are of U shape with their open sides disposed toward and receiving the ends of the glass plates 28 which constitute the louvres proper. The upper ends of the top sides of the runs or channels 27 are cut away as indicated at 29 (see Fig. 3) so that the inner face of the 'lower.

neled sides receive within them the forwardly projecting,

webs 12 The inner walls 26 of the runs 26 are of greater depth than the outer walls and these inner walls are pivoted by screws 30 upon the inner faces of webs 12 Heel portions 26 which project upwardly beyond said pivot screws are pivotally connected by links 32 to blocks 33. These blocks are adjustably mounted upon bars 14 through the screw and slot connections 34. Positioning and stop pins are indicated at 35.

The upper edges of the middle and lower panes are free, but the top edge of the upper pane is provided with a weather seal. This consists of a metallic plate 36 which extends along the top edge of the pane and is secured to the pane carriers at the ends of the latter. This plate 36 terminates in a goose-neck extension 37 which presents a forwardly facing free edge. This edge is embraced by a U-shaped packing strip 38 of soft rubber, neoprene, or the like. As the top of the louvre moves to closed position this packing strip makes firm contact with the rear face of an apron 39 which depends from the top 5 of the frame.

At the bottom of the window a sheet metal plate 40 serves to house the torque rod and to present a forwardly facing free edge 41 which carries a soft rubber or neoprene packing strip 42 with which the rear face of the lower portion of the lower pane makes water-tight contact when the pane moves firmly to closed position under the action of the operating handle. The plate 40 also (See Fig. 6.) The ends of the- 3 I ekercis'esa gutter-like function for the reception of any rain which might find its way thereinto if asudden shower found the jalousie partly open. Since the gutter is not water-tight at its ends any rain therefrom can find its way to the silP and thence totheoutside'ofthe'buildings The weather excluding; functions performed by'the" upper and lower seals andbythe engagement of the outer walls ofcha'nneIs-2'6 behind webs 12 are comptlete'd by flaring or enlarging the lower endsof chan-- nels' Z6'a's shownat 26in Fig. 5' so that these widened channels may fit over and embrace the upper faces" of the'channels 26-of the-louvresneXt below. By referring to" Fig. 6-it will be seen that the runs 27 he at a-slight' angle-with respect terms 26 so" that the desired over lapping effect'ofthe louvres may be had. This disposition" ofru'ns 27 at an angle disposes-their upper por-* tionsislightly below the'upper portions of the upper ends of runs 27 Z This leaves runs 27' projecting slightlyaboveruns 26 and itis' this upwardlyprojecting portion. which is embraced for a short distance by the flaredlower end 26 of the run'next above.

From the foregoing description it will be seenthat this device presents a jalousie window which while of the utmost simplicity isabsolutely water-tight under all' con-- ditions of use. It comprises relatively few and inexpensive parts. It is of rugged construction and not likely to get out oforder. The independent adjustment of every louvre together with the actuation of each louvre-- from each-"end, permits the use of longer and wider panes While insuring that accurate, glass to glass contact maybemaintained throughout the length of said panes; This renders itpossible to use the described construction in awning windows where larger and heavier panes are eniployed than is the case with respectto simple jalousies.

- The invention is not limited to the precise construction described but includes within its purview whatever changes fairly fall within either the terms or the spirit of the appended claims.

I claim: 1. In ajalousie structure of the character described, a pair of spaced vertical frame members defining'the sides of an opening to be closed and the inner faces of which. are vertically channeled to provide guideways, a pair ofactuator bars mounted for vertical sliding movement in said guideways, manually operated means connected to and moving said bars vertically and in unison, a plurality' of louvre sections, each comprising. a glass panel. extending across said opening and carriers for said glass panels, said carriers comprising members of channel form- 4 ation within which the ends only of the glass panels are received, said carriers being'pivoted by horizontal pivots upon the frame members, the said members of channel formation being so constructed that the lower rear face of one glass panel may overlap and make glass to glass contact with the upper outer face of the glass panel of the louvre next below throughout the entire length of said panels, actuating links connecting the actuator bars with the saidcarriers whereby to rock thecarriers by vertical. movement of. the actuator barsand adjusting. meansincluded in said linlcconnectionsfor independently adjusting the throw of each of the. links with thecarrier which it actuates, whereby the pressure exerted by every glass-panel against the panel which it"enga'ges' maybe independently adjusted at each end. of the panels.

2. A structure as recited in claim 1 wherein said adjusting means comprises blocks mounted for adjustment along the length of the said bars and to which the said links are pivotally connected.

3i A structure as recited in claim 1 wherein each of said carriers comprises two elongated channel-like members'U-shaped incross section and secured to each other to'move as a-unit, the open side of the inner of said members facing toward' and receiving the end portions only of the said glass panels, the open side of the other and second of saidmembers facing. rearwardly of'the' opening, the outer wall of the first of said members be ing cut away at its top to exposethe front face of the glass panel which it carries andthe inner walls of said members being cut away at their-lower ends to leave uncovered the lower inner faces of the glass panels, to

thereby permit glassto glass contact of the contacting portions of saidpanels throughout their length;
