IMPROVEMENT IN WINDOW-SCREENS.

Specification forming part of Letters Patent No. 151,599, dated J une 2, 1874; application filed March 11, 1874.

To all whom it may concern:

Be it known that I, THOMAS KELLS, of Green Point, in the county of Kings and State of New York, have invented a new and useful Improvement in Mosquito-Screens for l/Vindows, of which the following is a specica- JtiOn: l

Figure l is a face view of my improved mosquito-screen, showing it applied to a window. Fig.l 2 is a horizontal section on the line c c, Fig. l 5 and Fig. 3 is a detail side view of the screen case or shell.

Similar letters of reference indicate corresponding parts in all the iigures.

The object of this invention is to provide for a convenient and economical attachment of a mosquito net or screen to a window, and for its convenient removal at any time when it may not be needed.

The invention consists in providing a roller, which is placed at one side of the windowsash, within a slotted surrounding` shell, and around which roller the mosquito-screen is wound with a cord, which will wind around the roller when the mosquito-net is unwound, and which will enable a person desiring to wind up the net, by stretching the cord, to re volve the roller, and thereby wind up as much of the net as may be necessary.

In the accompanying drawing, the letter A represents a window-frame of suitable kind, and B the lower sash thereof, Fig. l showing such lower sash raised. O is a preferably about semi-cylindrical shell or case, within which a roller, D, has its bearings, the ends of the roller having suitable gudgeons that enter sockets or bearings in the closed ends of the shell C. At one side the shell is entirely open, as indicated in Fig. 2, and with this open side the shellis to be placed against the window-sash B, but in close proximity to one side of the window casing or frame A. All ordinary windows have an inner bead-lin- Y. ing inside of the sashes, and against this linconcealed within the shell C, when it is not intended to be used; but when to be used,

-it is withdrawn from the shell and unwound from the roller, in the manner indicated in Fig. 2-that is to say, it passes from the roller toward the sash B, between the sash and the edge i of the case O, as shown, and thence along the face of the sash toward the opposite side of the frame A, there to be attached by suitable means to such frame A. The means I prefer to use for this latter-named purpose consists in the use of a bar, a, which lines the loose end of the mosquito-net, and which, when placed against the frame A, can be readilylocked thereto by a hook, b, or other suitable means. A cord, d, is also wound around the roller D in opposite direction to the way in which the net E is wound around the Same, the end of such cord passing out through a slot, g, of the shell C. By means of this cord, the roller D can be readily turned whenever the cord is pulled, and the net E thereby stretched-that is to say, the roller turned in such way as to wind up as much of the net as is necessary' to hold the same stretched.

Vhen it is desired to dispense temporarily only with the use of the net, it is only necessary to unloosen the fastening b, and to pull the cord d, so as to wind the entire net upon thc roller D, and then again when it is desired to use the net E in front of the window, it is only necessary to pull 4on the rod a and carrythe same. toward the opposite side ofthe frame A, and lock it to the fastening b. But when it is desired to entirely dispense with the net E for a longer period-as, for example, during` the colder seasons-it is very easy to detach the shell O, with all its appurtenances, from the frame A by merely lifting it slightly, and withdrawing it from the holding-screws c. The entire apparatus can then be placed away conveniently, and kept ready for further usc.

I do not broadly claim the combination of a mosquitdnet, roller, and shell, but

The combination of the cord d with the roller D, mosquito-net E, and surrounding slotted shell G, all arranged for operation substantially as described.
