3 Claims. (01. 189-62) assembly that can be closed tightly to exclude light, rain and wind.

Another object of my invention is to provide a louver assembly that can be readily opened to admit light and air.

. Another object of my invention is the provision of a channel bar which is pivotally connected to each of the louvers whereby when the louvers are operated to their closed position the channel bar straddles end flanges on the ends of the louver as well as the side frame bracket or flange to which the louvers are pivotally mounted.

Another object of my invention is the provision of a channel bar which cooperates with the louvers and with the flange to which the louvers are pivoted so that when the louvers are moved to their closed position the channel bar makes a tight weatherproof construction.

Another object of my invention is to provide a frame with slots and ears to register for accurate assembly in the field.

Another object of my invention is to provide a jalousie or louver construction which may be completely assembled in the field whereby all of the parts may be shipped unassembled.

Another object of my invention is the provision of a jalousie or louver construction in which the pivotal mounting members or pins may be riveted or staked in the field when assembling the construction.

Another object of my invention is the provision of louvers. which are provided with longitudinally extending ribs which give strength to the louvers.

Another object of my invention is the provision of rolling one of the edges of the louvers to provide a rod-like construction on said edge, whereby the rod-like construction provides extensions for riveting the louvers to the channel bar by removing a small portion of the material next ad acent the rolled edge.

I Another object of my invention is the provision of operating and locking means for adjusting the position of the louvers, whereby the louvers when adjusted to their proper position may be locked.

Other objects and a fuller understanding of my invention may be had by referring to the following description and claims, taken in conjunction with the accompanying drawing, in

Figure 6 is a side view of the channel bar only;

Figure 7 is an enlarged cross-sectional view of the right-hand side frame member of my construction, and shows particularly the manner in which the louvers are pivotally connected to the side frames and the, manner in which the louvers are connected to the channel bar; and/ Figure 8 is a view similar to Figure '7 but shows the louvers moved to their closed position, which illustrates the'manner in which the louvers are madewaterproof to exclude light, rain and wind.

With reference to the drawing, my louver or jal-ousie construction comprises a top frame rail 10, a bottom frame sill II, and two side frames I2 and 13. These frame members may be made of sheet metal or any other suitable material and are arranged to be shipped in an unassembled manner and. assembled in the field. As illustrated, the top frame rail l0 and the bottom frame sill H are provided with tabs I4 which are arranged to extend through slots 15 in the side frames, after which the tabs may be bent over for locking thelframe members together. The frame members may be further tightly fastened together by means of a bolt l6 which extends through openings I! in the side frame and openings It! in the top frame rail and the bottom frame sill. The bolt l6 may be provided with a nut l9, whereby when the bolt is turned down tight the frame assembly is rigidly held together.

Each of the side frames is provided with a bracket 22 which has a spaced flange 23 so that when the bracket 22 is connected to the side frame the spaced flanges 23 are disposed at a spaced distance from the side of the frames. ,The bracket 22 may be anchored or fa'stened 't'o the side frame by any suitablemeans such as by 3 spot welding whereby the bracket 22 becomes a fixed part of the side frame. The spaced flange 23 of the bracket 22 is arranged substantially parallel to the side face of the side frame and is provided with openings 25 which are in alignment with the openings 2a in the side frame. The aligned openings are arranged to receive pivot pins 33 which pivotally anchor a plurality of louvers 3i between the side frames. The ends of the louvers are provided with end flanges 32 and each pivot pin 33 is arranged to extend through an opening in the end flanges 32 of the louvers. After the louvers 3| and the pivot pins 33 are assembled, the ends of the pivot pins 33 may be staked as indicated at 3% whereby they become permanently anchored in the side frame. The staking operation may be done by any suitable tool and is arranged so that the staking and assembly may be done in the field before the. slde frames are fastened to the framework in which the jalousie or louver construction is adapted to be mounted. The framework into which the jalousie is adapted to be mounted is illustrated by the member 26 and the side frames may be anchored thereto by wood screws 2! that extend through openings 26 in the side frame. As illustrated in Figures 7 and 8, the side frames are provided with inturned faces 27 and 28 which rest against the supporting structure in which the jalousie or louver construction is adapted to be mounted. The inturned face 2'! is part of the bracket 22 so that When the side frame is anchored to the supporting structure 26 the bracket 22 becomes directly anchored to the supporting structure 25. As shown in Figures 3, 4

and 5, the upper edge of each of the louvers is rolled as at 35 to provide a rod-like construction upon the upper edge thereof. As shown in Figures '7 and 8, the end corners of the louvers are cut away at 29 to provide rolled extensions 36' in which the rolled extensions 36 function as rivets whereby the louvers may be connected to a channel bar 37 for operating the louvers simultaneously. Each end extension 36 is adapted to extend through an opening 38 after which the end may be upset or riveted by any suitable tool in the field. The rod-like rolled end of the louver provides for rendering the louver rigid in construction from end to end. The central part of the louver is provided with a V-shaped center rib 4B which also aids in srengthening'the louver against bending or deformation. The lower edge of the louver when in its closed position is provided with a V-shaped lower rib 4'! which also aids to strengthen the louver.. As shown best in ,ears 48 through which the openings 38 are provided. The side wall 39 of the channel bar is spaced away from the side frame so that as the channel bars 3'! and the louvers are operated there is complete freedom from interference with the side frame. 'ble by the employment of the bracket 22 which .has the spaced flange 23 located at a reasonable clearance distance. from the side frame.

This construction is made possi- Also, 1

the positioning of the spaced flange 23 as a dis tance from the side frame makes is possible to give rigid stability to the pivot pin 33 which supports the louvers.

Attached to the lower end of the channel bars 3? are extensions 49. As illustrated, these extensions 19 are hingedly connected to the lower end of the channel bars whereby when the channel bars are actuated up and down for operating the louvers the extensions are arranged to move to permit such up or down actuation of the channel bars. The hinged construction is provided by means of a pin 59 which extends through openings 53 in the channel bar and slots 54 in the extension A9. A washer 5! may be mounted over the pin 53 prior to the insertion of a cotter pin 52 for keeping the assembly together. The lower end of each extension 49 is free and when the channel bar 37 is moved downwardly the end of the bar extension 69 engages the bottom frame sill after which the extension 519 swings outwardly along with the outward movement of the channel bar 31.

The louvers are arranged to be locked in an infinite or great number of positions by means of a locking assembly which comprises a stationary bracket 55, a connecting link 59, and a knob TI. The upper end of the link 5.9 is adapted to be pivotally connected to a mounting plate 5'! that is suitably anchored to the outside face of the channel bar The mounting plate 51 is provided with ears 58 having openings 60 therein through which a pin 82 is arranged to be mounted. The pin 62 extends through openings Si in the link 59 and the opening 60 in the ears 58, after which a cotter pin 63 is inserted through the end of the pin for holding the assembly together. The lower end of the operating link 59 is provided with a pivotal block (i which is connected to the operating link 59 by means of a pivot pin 8? that extends through openings 65 in the lower end of the link 59 and an opening 55 in the pivoted block 66. The pivoted block 5 3 is provided with a threaded extension 89 onto which the knob H isthreaded. A washer 10 may be placed between the knob. H and the pivoted block 8 As illustrated in Figure 2, the threaded extension 69 is adapted to extend through an elongated slot 55 in the stationary bracket 55, whereby when the knob is turned tight against the stationary bracket 55 the louvers are held in a fixed position. The louvers may be moved by unloosening the knob H and then sliding the pivoted block up and down whereby the link 59 operates the channel bar to which it is attached for adjusting the position of the louvers, after which the. knob ll may be again retightened for holding the channel bar in a fixed position.

As will be noted from the entire description and drawing, the jalousie or louver construction may be assembled in the field whereby the entire construction may be shipped to a designation in an unassembled condition. After complete assembly, the louvers may be operated to any number of predetermined positions by the operation of the knob 7|. When the louvers are operated to the closed position each channel bar 3'! straddles the end flanges 32 of the louvers as well as the spaced flange 23 so that the entire construction makes a weatherproof assembly which excludes light, rain and wind.

The end flanges 32 extend laterally from the ends of the louvers and correspond in length substantially to the width of the louvers, except for the cutaway notch 29 in one of the corners which makes clearance for the rolled extension 36 riveted to the channel bar 31.

Although the invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention as hereinafter claimed.
