GEORGE L. REYNOLDS, OF OAKLAND, CALIFORNIA.

WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 268,125, dated November 28, 1882.

Application filed June 3,1882. (No model.) i

To all whom it may concern Be it known that I, GEORGE L. REYNOLDS, of Oakland, county of Alameda, State of California, have invented Improvements in Window-Screens; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to certain improvements in window-screens of that class in which upper and lower wire or other screens or ourtains are attached at one end directly to .the sashes, so that when the latter are raised or lowered to open them the screens or curtains will be extended over the opening, and thus exclude flies, mosquitoes, and other insects without excluding the air.

The invention consists in a means for attaching the screens or curtains at the top or bottom of the window so that they may be easily detached, a means for keeping the edges of the screens tight, and also the space between the lower bar of the upper sash and the glass of the lower one, and the construction of the screen-weight, which allows it to pass the pulley at the top, and thus have more distance through which to move, which, with the details of construction, will be more fully explained by reference to the accompanying drawings, in which- Figure is a view of the window with the lower sash raised, showing the screen and the side springs to keep its edge close. Fig. 2 is a view showing both sashes partly open. Fig. 3 is a vertical section taken transversely across the sashes and screens. Fig. 4 is a front view, showing both sashes open and the balanceweights, cords, and pulleys. Fig. 5 is an enlarged section of a screen-roller and cord-drum. Fig. 6 is an enlarged view of section of window-sash, frame, screen, and means for forming a tightjoint with the screen edges. Fig. 7 is transverse section, showing the manner of incasing the roller. Fig. 8 is a section of weight, showing the manner of hanging it so that it may pass partly above the pulley. Fig.9 is a detailed view, sh owingthe vertical elastic strip to keep the screen taut. w

A is a window-casing; B and B, the upper and lower sashes, glazed in the usual manner, and G O are screens of any suitable material, having one edge fixed to the top or bottom of the window-casing and the other edge to a roller, D, which is fixed to turn upon the top or bottom edge of the upper or lower sash-rail, as the case may be. These sash-rails are slightly grooved to partially admit the screenroller, but not so as to cut away too in ueh of the material, and thin metal plates E are secured to the sides of the rail, projecting far enough to inclose the screens and rollers and protect them. Spurs or guides at project just inside the edges of the outer plates, so that the edges of the screens pass between the spurs and the outer plates, E, and are kept in place by them. The upper and lower edges, respectively, of the screens are made fast to bars F, so that when drawn up to the top in one case and down to the sill in the other they may be fastened there by means of buttons G, and these hold them so that when the window-sashes are opened the screens will unroll and close the space above or below the sash. \Vhen it is desired to leave an open space at these points the buttons are turned and the screens are allowed to roll up against the sash, thus leaving the window in its ordinary condition.

The sashes are balanced by a single weight connected with one side by a cord passing over a pulley in the usual manner. The weights H H upon the opposite side are connected with drums or spools I, which are secured to the ends of the rollers, so that as the sashes are moved the screens will be rolled or unrolled. The cord J, which connects the drum I and weight Hoftheupper sash, winds up as the sash is lowered andnnwinds when the sash is pushed up, and this causes the weight to move over double the distance necessary. The weight is cutaway with a deep channel on the inside, extending to the bottom, as shown in Fig. 8, and the cord passes down in a groove which slopes backward from a nearly central point at the top to a hole, where it passes out at the back near the bottom, and thence it is carried through ahole at 'thebottom and into the channel, where a knot in the end retains it. The weight hung in this manner keeps its upright position as the top inclines toward the cord, and when it arrives at the pulley at the top the channel fits over the pulley, as shown in Fig. 8, while the cord passing over the pulley, as shown in the dotted lines, allows the upper part of the weight to pass above the pulley.

In order to keep the screen edges pressed against the strips between the sashes, so that they will not spring away and leave an opening through which insects may haveingress, I fix one end of thin flat curved spring K to the inner side of the strips L, between which and the strip L the window-sash moves. When the sash is closed it forces the spring back, straightening them out against the strips to which they are secured; but when the sash is opened the free ends of the springs curve forward and press against the edges of the screens, and thus hold them against the strips L.

In order to make a tight joint between the netting or screen and the strips L from the sides opposite to the springs K, I makea groove or slot, M, diagonally in the edge of the strip L and insert a thin strip of rubber or other elastic material, N, so that its edge projects a short distance. This edge may be straight, wavy, or scalloped, as shown, and when the window is closed the edge rests against the vertical part of the sash. When the window is opened the angle at which the elastic piece is fixed in the window-strip L causes it to press against the screen as'it is unrolled, and thus keep a close joint.

I have heretofore described my improved devices as applicable to window-screens; but it will be manifest that they may also be used with curtains or an y other flexible fabric where a close joint is desired.

For convenience I have described the screen as fixed to the edges of the sash; but in case the windows are arched at the top the upper one may be fixed above the arch in the casing, and the lower edge of the screen have a curved bar or plate, F, which will just fit the curved top of the window, and may be secured to it in the same manner as described for securing the straight-ones to the window-sill or top of casingthat is, by buttons G. p

A strip of elastic material, 0, is fixed across the lower rail of the upper sash, and it projects so as to touch the glass of the lower sash and close the opening which would otherwise v be made when the windows are opened.

Having thus described my invention, what I claim as new, and desire to protect by Letters Patent, is-

l. In a window-sash, the transverse rail or rails having the rollers D journaled to them, with screens or curtains attached, as shown, the free edges of said screens or curtains having plates F fixed to them and adapted to be secured by buttons G, substantially as herein described.

2. In a window, and in combination with the screens or curtains O, the elastic curved strips K, fixed at one end, so that the free end is held back when the window is closed and springs forward to press against the edge of the screen or curtain when the window is opened, substantially as herein described.

3. In a window, and in combination with the screen or curtain G, the elastic strip N, fixed in the vertical strips L of the window so as to press upon the edge of the screen or curtain when the sash is opened, substantially as herein described.

4. In a window, and in combination with a sash having a rolling screen or curtain journaled upon its edge and operated by a balance-weight, the weight H, channeled upon the side next to the pulley,-and having the suspending-cord J passing down through the channel and secured at the bottom, substantially as herein described.

5. In a window-sash having a screen or curtain roller journaled on the transverse or meeting rail with the inclosing plates or case E, the spurs or guides a, between which and the outer plate, E, the edges of the screen pass and are kept in place, substantially as herein described.

In witness whereof I have hereunto set my hand.
