1 2,785,446 JALOUSIE TYPE WINDQW CONSTRUCTION Arthur Silverman, Newark, N. J. Application December 15, 1953, Serial No. 398,262 1 Claim. (Ci. 2tl-62) This invention relates to window structures and has particular reference to windows of the jalousie type having a plurality of horizontally swung panels to be shifted in unis-on in a vertical plane.

A prime object of the present invention is to provide novel mechanism for supporting the several panels or louvres with their horizontal edges in overlapping relation, throughout their lengths, in weatherproof engagement and with the several panels being angularly disposed in an identical manner with respect to the side jambs of the supporting frame structure.

Another object of the invention is to provide a carrier or bracket assembly of relatively light sheet metal having portions constructed and arranged effectively to support the ends of glass panels for rotational movement as well as to grip the panels in a manner to resist their removal and prevent rattling.

A further object of the invention is to provide a novel actuating bar for supporting the various panel supporting assemblies whereby said assemblies may be readily shifted in unison and are securely held against accidental opening when in closed position.

Still another object of the invention is to provide means for sealing the top and bottom ends of the window construction against the weather and storms.

A specific object of the invention is to provide a carrier or bracket assembly for a glass panel with a resilient and flexible device for clamping the panel against removal and rattling.

Yet another object is to provide a carrier or bracket assembly for a glass panel or the like wherein the panel may be readily inserted, and secured against removal and rattling.

It is further proposed to provide a window structure of the jalousie type which can be readily installed in new constructions and can readily be installed to replace old windows in homes, porches, buildings and breezeways.

A still further object of the invention is to provide a window structure of the jalousie type which is strong and durable in construction and which can be easily and quickly assembled, and to obtain other advantages and results as will be brought out by the following description.

Specifically describing the illustrated embodiment of the invention, the reference character 1 designates a wooden building with a window opening 2 formed therein. The frame shown installed in the window opening comprises a sill 3, a header 4 and jamb members or stiles 5.

The sill 3 consists of upper and lower nested channelshaped plates 6 and 7, respectively, forming a box-like structure. The upper plate 6 has downwardly extending front and

rear flanges

8 and 9, respectively, and end flanges 10 secured to the jamb members or stiles 5 by rivets 11. The front flange 8 of the upper plate 6 continues into an outwardly extending flange 12 which terminates in a downwardly extending flange 13 for closing the lower end of the window opening. A sealing strip 14 of felt, rubber or other suitable material is placed against the outer surface of said front flange 8 and is secured thereto by a bead 15 formed along its top edge and fitted into a groove 16 formed on the front flange adjacent its top end.

The header 4 comprises a flat plate 17 with end flanges 18 secured to the jamb members or stiles 5' by rivets 19. The plate has downwardly extending rear flange 20 continuing inwardly to form a flange 21 parallel to the plate, the latter flange terminating in a downwardly extending flange 22. At its front, the plate. 17 is formed with an upwardly extending flange 23 which closes the top end of the window opening and with a downwardly extending flange 24 formed with a grooved rib 25 on its inner surface for receiving and securing the beaded end 26 of a sealing strip 27 of felt or the like.

The side jamb members or stiles 5 are box-like in form, each including a front wall 28, a rear wall 29, and outer and

inner side walls

30 and 31, respectively. The inner side wall 31 terminates in a laterally extending flange 32. The laterally extending flanges 32 on the stiles 5 are aligned with the downwardly extending flange 22 on the header 4 and with an'upwardly extending rib 33 formed on the upper plate 6 of the sill 3. The front Wall 28 of each stile continues inwardly to form a flange 34 and continues outwardly to form a flange 35. The flange 34 is disposed in a plane approximately perpendicular to the general plane of the frame. Outer flange 35 terminates in a laterally extending flange 36 which is parallel to the front wall 28 and has an integral extension 37. The extensions 37 close the sides of the window opening.

According to the present invention, the closure for the window consists of a plurality of rectangular-shaped preferably transparent panels 38 adapted to be supported within the window opening in a manner to swing in a vertical plane. The several panels are horizontally arranged and are supported at their opposite ends for swinging movement by end brackets or carriers designated as a whole by the reference character 39. As shown in Figures 1 and 3, the panels 38 when in closed position are angularly disposed with reference to the faces of the jamb members or stiles 5 and lie in overlapping and contacting position throughout their lengths. The panels may be formed of glass, plastic or the like and may be in various combinations of transparency and certain of the panels may be colored for the purpose of controllling the brilliance of the light.

As shown in Figures 11 and 13, each end bracket or carrier 39 is formed of a single piece of metal, preferably aluminum and embodies an elongated angular hollow panel supporting body in the form of a split tube having top wall portions 40, a bottom wall portion 41, and side wall portions 42 and 43. The top wall portion at its front end projects beyond the front ends of the side wall portions to form an extension-4.4, One side edge of the extension is bentat rig-htangles to form, aflange 45 and its end edge is similarly bent to form an end flange 46. The side wall portion 52 projects beyond the rear end of the top wall portion to form an extension 47. The free end of said extension-is slottedas indicated at 48 and above the slot the extension is bent at right angles to form a flange 49, and belowv the slot is formed with an offset downwardly extending arm 50 tapering outwardly to a rounded end provided with an opening 51. The top of the side wall portion 43 ends below the top wall portion to provide a slot or clearance 52 that faces the slot of the corresponding bracket on the other stile. Bottom wall portion 41 tapers downwardly and outwardly toward the front extension dd ofthe top wall portion and together with the side wall portions 42 and 43 form a channel 53 below the top wall portion' The channel 53 is longitudinally tapered between the top and bottom walls and is open at both ends but is providedcwith its wider opening adjacent to and below the flanged end of the extension 44.

The bracket or carrier 39 may readily be mounted on the end of the glass panel 38 by. inserting said panel end through the opening or clearance 52 provided between the top wall portion 40 and the top end of the sidewall portion 43 so that the long edge ofthe panel will abut against the side wall portion 42 and the aligned extension flange 45' and its end edge will abut against the end flange 46 on the extension 44. A glass panel 33 is secured in position in the bracket or carrier by an elongated clamping device 5-; of channel formation and tapered longitudinally. The clamping device is formed of sheet metal and embodies a base wall SS'and' side walls $6 and 57. They-device is inserted longitudinally through the wide opening of the channel 53 with its base wall 55 positioned alongside the narrow side wall portion 43, and is slid along the channel with its side wall 56 pressing against the inner surface of the glass panel 33 thereby forcing said panel against the top wall portion 40 of the bracket and thus resiliently holding the panel against displacement or removal and against rattling. A protuberance 53 on the side wall 57 of theclamping device is adapted to spring into a recess 5% formed on the bottom wall portion 41 of the bracket to assist in holding the clamping device in operative posit-ion. Thepanels are thus firmly secured endwise and edgewise as well as being firmly gripped between the top wall portion 40 and the clamping device 54' so that rattling is prevented whether the louvres are open or closed.

On one side of the window opening a plurality of brackets, or carriers 39 are mounted on an elongated actuating bar 6i) having a U-shaped body with opposed flangcs 6i therealong. The actuating bar is slidably and swingably mounted in theiadjacent stile or jamb 5 behind the front wallZSof the stile with its body portion opening outwardly toward the front so as to receive the arms 50 of the brackets 3d and to receive the, inwardly extending flange 34 on the front wall 28. A series of opposed and aligned openings 62 is formedin and along the body portion of the bar for supportingpins 63 which pass through the openings 51 in the bracket arms 5% for connecting the brackets to the bar. Suitable means e. g, lugs Slit: on the arms 50 are provided for holdingthe bracketarms at one side of the channel in the corresponding actuating bar 60' so as to ensure a clearance for the flange of the correspondingstile or jarnb 5 when the panels or louvres 38' are in closed position as best shown in Figure 5.

On the other side of the window open-ing and likemounted. on a similar actuating bar 60 are a plurality of opposed. brackets 23), the axes of the supporting pins on the opposed brackets being in alignment. In each instance, the brackets are of a size and so shaped that they carry the ends of the panels 38 as shown in Figures 1 and 3 in position to overlap one another in the closed position and to provide substantial intermediate openings when open as shown in Figure 4. When closed, the uppermost panel 38 engages the sealing strip27, and the lowermost panel 38 overlies the sealing strip 14.

It will be noted that when the panels 3-8 are in their closed positions the bottom walls 41 of all of the brackets 39. are disposed in approximately the same vertical plane as shown in Figure 3; and as shown in Figure 5, the

flanges 34 on the stiles or jambs 5 arev embraced by the.

corresponding actuating bars 69, the flanges 34 being disposed within the channels of the actuating bars, and the flanges 61 are in closely spaced relation to the front walls Zfiof the jambs and to the bottom walls 41 of the brackets 3?, respectively, thereby forming tortuous passages to restrict the flow of air and moisture between the stiles or jambs 5 and the actuating bars.

The mechanism for effecting opening and closing movements of the'brackets and. panels in unison is under the control of a crank 64. A gear housing 65 is mounted on the outside of one of the stiles 5 and is secured thereto by screws 66. The housing contains a shaft 67 which extends outwardly thereof and mounts the crank 64 where by it is turned. A worm 68 on the shaft 67 drives a gear 69 on a shaft 7d which projects outwardly of the housing. A lever '71 has one end secured to the protruding end of shaft 7i) and passes through a cutout portion 72 of the adjacent bar 6d and has its other end secured to one end of a link 73, the other end of the link being fastened to one of the pins 63 on the adjacent actuating bar 6%. When the crank 64 is operated it rotates the lever arm 71 thereby moving the actuating bars 60 in an arcuate path and thereby effecting angular displacement-of the panels for opening'or closing the window as will be understood.

While I have shown and described the invention as embodied in certain details of construction, it should be understood that this is primarily for illustrating the principles of the invention and that many modifications and changes may be made in the details of construction without departing from the spirit or scope of the invention.

Having thus described my invention, what I claim is:

In a window structure including a frame having a header, a sill and parallel stiles having front and rear walls connected by a side wall, a plurality of panel supporting brackets pivotally mounted on horizontal axes on each of said stiles, elongated actuatingbars between said front and rear walls, each pivotally connected to all of. said brackets on one stile, a movable link member connected to one of said bars for imparting longitudinal movement to the actuating bars, panels supported in the brackets, and means for actuating said link for shifting the support ing brackets and panels in unison into open and closed positions, each of said stiles having an inwardly projecting longitudinal flange disposed in a plane approximately perpendicular to the general plane of the frame and each of said actuating bars having a longitudinal channel to fit over the corresponding said flange in embracing relation thereto when said panels are in closed position, said brackets having flat bottom walls which are disposed in substantially a common plane when the panels are closed, and each of said actuating bars having a lateral flange extending longitudinally thereof at each of opposite sides of said channel, said lateral flanges being disposed in closely spaced relation to the inner surfaces of said front walls of the frame and to said flat bottom walls of said brackets, respectively, when the panels are closed.
