SPECIFICATION forming part of Letters Patent No. 687,705, dated November 26, 1901.

Application filed December 19, 1900. Serial No. 40,444. (No model.)

To @ZZ whom t may concern:

Be it known that I, JOSEPH W. WALKER, a subject of the Queen of Great Britain, residing at Malden, in the county of Middlesex, State of Massachusetts, have invented a certain new and useful Improvement in Louver- Windows, of which the following is a specification, reference being had therein to the accompanying drawings.

In the drawings, Figure 1 shows in front end elevation a louver-window and supportingframe embodying my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a view in vertical section on the plane indicated by thedotted line 3 3, Fig. 1, looking in the direction indicated by the arrows at the ends of such line. Fig. 4 shows the slotted holding-bracket, to which reference is made hereinafter. Fig. 5 shows, partially in elevation, a modified embodiment of the invention. Fig. 6 is a view in vertical section on the plane indicated by the dotted line 6 6, Fig. 5, looking in the direction indicated by the arrows at the ends of such line. Fig. 7 is a view, on an enlarged scale, of details of the construction shown in Figs. 5 and 6.'

Having reference to the drawings, more especially t0 Figs. l to 4, the sections or louvers of my window are designatedl 1 1. The glass of the said sections or louvers is held inmountings 2 2 2, which are mounted upon horizontal pivots at 3 3 3 at the opposite ends of the sections or louvers, so as to enable the said sections or louvers to be swung or tilted to any desired angle about such pivots as may `be required in the use thereof. Fig. 3 shows the mountings provided, respectively, with arms 2a 2f* 2, which are connected pivotally, by means ofscrews 2b 2b 2* or other suitable means, with the operating-bar 3?, which enables the louvers to be swung or tilted in unison. For the purpose of operating the louvers conveniently a lever 4, mounted upon a suitable fixed pivot at 5, is connected pivotally with bar 3a, as by a pivotal screw 6, the said lever having attached thereto the cord 7. By pulling upon this cord the louvers may be opened more or less, as desired. For the purpose of holding the louvers at the required angles the cord 7 has applied thereto a notched orrackshaped handle 8, and a slottedbracket 9 is attached to a convenient fixed support. The notched or racked handie is slipped into the slot of the said bracket, which last by its engagement with one or another of the shoulders or enlargements of the handle holds the louvers in the position which is given to them. The louvers are pivoted above their centers or" gravity, and consequently after being opened more or less tend to assume their closed position. This tendency is overcome by the engagement of thehandle 8 with theslotted retainingbracket 9. This tendency may be aided, if deemed necessary, by a spring-box 10, mounted on the bar 3L and furnished with a linger 10?', that is arranged to make contact with the pin 11- on a xed support. The spring contained in the said spring-box acts with a tendency to bear the finger 10iL downward, the effect of which is to raise bar 3a and close the louvers, when such spring is permitted to act. The arrangement shown in Figs. 3 and 4 may be duplicated at the opposite side of the window in cases where the window is wide and the louvers are heavy.

In Figs. 1, 2, and 3 themonntings 2 2 2 are oblong rectangular frames, preferably of metal, although other material may be employed, receiving the glass and fitting the four edges of the latter. Figs. 5, 6, and 7 show an arrangement in which the mountings comprise simply end supports orside cheeks 21 21, receiving the opposite ends of the glass sections, the said end supports or side cheeks being pivoted at 22 22 and provided with arms, which are connected to an operating-bar 33. The attachment of the glass to the said mountings or side cheeks 2l` 21 may be effected in any convenient manner, although I prefer to employsprings 23, Fig. 7, applied to the mountings, the said springs being in the form of slightly-curved strips secured at intermediate points in their length to the respective mountings and each end of the glass being clamped between the opposite ends of a. spring and alateral flange 24 on thecorresponding mounting. This means of holding.,r the glass in place accommodates glass of any thickness and secures the glass tightly in place, what ever may be its'thickness.

Preferably the several louvers of a window are mounted, by means of thepivotal screws 3 3 3, within aframe 12, provided with holes IOO 13 13 13 for the passage of screws by means of which to fasten the window into a wooden frame or sash or wherever required to be held, and in such case lever 4t is connected with the said frame by the pivotal screw 5 and pin lla is attached to the frame also.

Louver-windows embodying my invention are capable of being applied to either new or existing window frames or sashes. They may be applied to both sashes of an ordinary Window, or to only one thereof, or to any desired portion of a sash. They may also be applied to doors in which openings for light or air are desired. In new work,wherein modifications of ordinary window design are more readily practicable, the weights, ropes, and cords of ordinary windows and the casings necessary therefor may be dispensed with by using my window in the upper half of the window-opening, while the lower half of the latter may be fitted with a sash or sashes swung on pivots opening inwardly to facilitate cleaning without risk. Y

In the modification shown in Figs. 5, 6, and 7 the mountings of the louvers consist only of side cheeks, with the necessary clamps to secure the glass thereto, thus dispensing with the top and bottom sides of the frames of Figs. l, 2, and 3. The meeting edges of the glass are in this case beveled and finished to form a waterproof closure.

When the louvers are used mainly to secure ventilation, the glass may be semi-opaque or ornamental. The arrangement of the louvers is such that when moderately opened the incomingcurrentof air enters obliquely in an up-v ward direction, thus avoiding draft on the one hand and tending on the other to diffuse the said incoming air throughout the upper part of the room or other space in connection with which my louver-window is applied. Vhen it is desirable to modify the direction orcharacter of the light admitted through the window, the louvers may be fitted with plain, corrugated, or other special reflecting or refracting glass or other medium. The louver-window thus fitted may also be applied tol secure the refracting and reecting action without being used as a ventilator. It would in that case be fixed wholly outside and independent of the windo wsash through which it is desired to obtain an increased amount or modified character of light.

I claim as my invention- In combination, the frame l2, the plurality of louvers consisting of glass sections and mountings for said sections, pivoted in said frame, the bar connecting said louvers in a series, the spring-box mounted on said bar and provided with anger engaging with a fixed point on` the frame, the lever for operating said bar, the cord connected with said lever, and adjustable holding means for said cord, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH W. WALKER.
