WINDOW SCREEN. 4

My invention relatesto closures and particularly to window screens.

One object of my invention is to secure a form of window screen that is simple in construction, cheap to manufacture, easily removable, and readily raised to a position allowing one to look out of the window.

Another object of myV invention is to permit the screen to fall by its own weight from an open to a closed position, and to become automatically locked thereby.

v Still another object is to make it impossible to raise the screen from outside when itis locked without destroying the screen itself or its attachments to the window frame.

A further object is to have the screen so far away from the window that it protects the window panes in case 0f rain.

Other objects of my invention are to increase ventilation when the screen is in a raised position, and to enable a window cleaner to operate without removing the screen.

Still other objects of my invention will become apparent from the detailed description which follows.

Referring to the drawings, Figure 1 is a front view of my invention. n

Figures 2 and 8 are Side views in cross section along the line 2 2 of Figure 1, the first one showing this cross section in 'closed position of the device and the second one being a view thereof when the device is in open position.

Figure 4 is a partial front view of the preferred form of my invention, namely, when the closure is a screen.

Figures 5 to 8 inclusive are details of my preferred and other forms of the device.

In reference to the Figures 1, 2 and 3, various parts thereof will now be described. The frame forming one of the elements of my invention is composed of the upper-cross rail 1, the lower cross rail 2, and the two

side rails

3, 3. The cross rails, as shown, have a greater depth than the side rails, but this feature is of no particular significance. The frame 1-23 may be of any suitable design and in accordance with the material used. Furthermore, itis not necessary to have an extra frame besides the one forming the window frame in a vwall opening, and it should be understood that the frame 1 2-3 may be Such a window frame, in which case the various attachments and connections described further below would be made div the linger of yan operator.

rectly on this window frame. The two brackets l fastened to the side rails 3 and having fork shaped ends constitute open bearings for the studs 5 on the corresponding brackets 6, the latter being fastened near the top of the closure 7 on either side thereof. The closure 7, which may be a window, a screen, solid boards, or of any suitable character, is composed of two sections, 7 and 7. The lower edge 8 of sections 7 and the upper edge 8 of section 7 slant at complementary angles so that they become contiguous when the closure is in the position shown in Figures 1 and 2. The arms or links 9, which are preferably flexible, are xedly attached to the sides of 7 flush therewith, near the edge 8, and revolubly connected with section 7, near the edge 8, at some point 10. A spring button 11, set into the side of 7 below the point 10, snaps into the opening 12 of the arm 9 when the

Sections

7 and 7 assume the closed position shown in Figures 1 and 2. Instead of the spring button and opening 12, I may use a round topped lug 11 and acorresponding depression 12 in the arm 9, the drawing, as shown, being adapted to illustrate either one of these arrangements. The button or lug 11 may be set into the side rail 3 instead of in the section 7, although this variation of the arrangement is ynot shown in the drawing, being obvious to any one skilled in the art. The vertical or side rails 3 are provided with longitudinal grooves 13 having offset notches 111. VThe grooves eX- tend high enough to allow section 7'to be raised to a position where a window cleaner may operate without inconvenience. At the lower end of section 7, fastened thereto and projecting laterally therefrom, are studs 15 which Slidingly fit into the grooves 13 and may rest in the notches 14. At the bottom, section 7 is provided with a lock 16, shown in detail in Figure 6. The lock 16 comprises a double hooked member 17 '-17 revoluble on the pin 18. The end 17 may engage the stop 20, fastened to the lower crossrail 2, under the action of the spring 19, while the Vend 17 may be engaged by 1t will be noted that the lock 16 can only be released by com-` pression of the spring 19, i. e. only from inside. The knob 21 on 7 enables one to control the motion of the sectional closure from an open to a closed position, and vice versa.

In Figure fl is shown a portion of my preerred Jtorni, iront view, dil'lering 'from the 'term shown in Figures l and 2 only in that the closure is ilically a screen.

ln Figure 5 is shown a different connection between the two sections i" and 7, namely a hinge 2Q. lt will be noted that the pin 23 o't' the hinge 22 should be in the center as regards the thickness ot the

sec tions

7, 7, in order to balance the motion ot the sectional closure when it is allowed to fall from an open to a closed position by its own weight.

Another modilication ot my invention is shown in Figure T, wherein l add an extra weight to the lower section 7 to facilitate the dowi'iward motion oi' the closure.

in Figure 8 is shown a variation ot my invent-ion wherein the closure` is connected with the upper cross rail l by means of a hinge 25, in lieu ot the c et pivotal arrangement shown in Figure.; l, 2 and 3.

rlie invention is so simple that its operation is almost obvious. The Jfollowing remarks, however, nry be pertinent.

Having in infinl J principally, the form ot my invention which embodies a window screen, the traine 1 2-3 should be set in the wall opening as .tar away from the window as possible, or, it an existing traine in the opening is utilized, the guiding grooves l?) and pivotal connection between the screen and the window frame at the top should be made as tar away from the window as practicable. )his will prevent rain from beating on the window panes. lt will also increase ventilation. Ventilation is noticeably increased also by the inclined position oJ the screen Sections in open state. The grooves 13, by not extending all the'way up, prevent the sections from becoming over-inclined and raised to a point where tl screen may drop Ll out ot its open bearings l. The oli-set forni ot pivotal connection shown in Figures l. il and 5l, between the 'trame and the fjfcreen at the. top, is preferable to the hinge shown 'in' the Figure 8, as the motion oi the screen up and down is more iree, owing to greater eelt adjustability otthe various connections and :i more effective bzilancing oi the parts. As shown, the closure complete and tight, the slanting edges 8', 8, constituting a joint impenetrable to flies and other insectsn To raise the screen from a closed and locked position, press slightly forward when engaging the hooi: 17 and pull back when the screen is su'tliciently raised, thereby lodging the stud l5 into one of the notches le. Vhen closing, reverse the operation. In the case of a screen, it is not necessary to lead the sections downward, as one would have to do Y in thc case of a. window, to avoid breakage, but the screen may be allowed to fall ot its own weight. rlhe moment it reaches the po sition shown in Figures 1 and 2, the resilient Ysaid trame, a slidingv connection embodied in the arms 9' will cause the two sections to become firmly joined, and at the same time the'lock 16 will become operative and set. In this position the screen can not be opened or raised from outside without breaking one ot' the connections. TWhen t i screen raised, it may be removed 'from the trame by the mere act of lifting it ont ci its open bearings My invention is particularly well adapted to light construction of Vclosures orP any kind, but l do not mean to lim-it lmyself to such light construction, nor to the particular'.
