SPECIFICATION forming part of -Letters Patent No. 293,915, dated February '19, 1884.

To @Zlio/00771, it 171160,11/ concern:

Be it known that I, J AMEs IRviNG SPENCER, a citizen of the United States,'residing at Chelsea, in the county of Suffolk and-fState'of Massachusetts, have tingr/entedii'ain new and useful Improvemen s in Fly-Screens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which forma part of this specification.

This invention relates to fly-screens of the sort employing a spring-roller and a sheet or strip of flexible material adapted to be wound automatically thereon; andthe said invention consists in a roller having a rabbet, in combi-A nation with a iiexible eXtensible screen attached to said roller and having re-enforcing bands or folds, and adapted to be wound thereon, and a longitudinally-slotted cylindrical casing adapted to contain said roller and screen, and having said roller journaled in the ends thereof, said casing and its contents be? ing readily removed from and attached to the wood-work as a single piece. The drawings accompanying this specification represent, in Figure vl, a View of a window and window-frame with my invention applied thereto. Fig. 2 is a horizontal section of the screen and its roller and containing-case. Fig. 3 is a view of the roller, showing the groove to receive the lap of the screen.

In said drawings, A denotes a window-frame,

and B the lower sash of a window.

In carrying out my invention I provide a straight tubular case, D, having a longitudinal slot, E, to permit of the passage of the screen. This case contains a roller, F, journaled longitudinally Within it, and upon the roller the screen is wound by means of a spring suitably appliedsaid roller being removable withl saidcase. Y

v G represents a screen in the form of a piece of netting of any suitable material, the inner end of which is secured to the roller F, while its outer end is secured toa strip, H, of wood or other material, containing a ring or catch, I, to engage a stud or fastening secured to the opposite side of the window-frame. The case D is to be secured in an upright position to one side of the window-frame, as shown, and whenit is desired to screen the lower part of the window the netting G is stretched across .such window and secured to the opposite side of the window-frame, as shown in Fig. 1.- 1YVhen released, the netting is automatically coiled within said case D by the action of the spring applied to the roller. Under ordinary circumstances the netting G, in the event of a high windblowing into the window, would be swelled out and separated at top and bottom from the window-sash, thereby permitting of entrance of iiies. result, I employ, as one means of effecting the desired result, a narrow band, J of webbing or other suitable material, whichI dispose at thetop or bottom, or both, of the netting, and so as to somewhat overlap the latter, as shown in the drawings,-the inner end of each band being secured to the roller F, while its outer To avoid this objectionable end is secured to the. bar H. As the narrow -both edges of thescreen, thereby providing a fullness of the screen, to permit the latter to be distended bythe wind without separating its edges from the windowsash. The inner edge of the slot in the case D serves to maintain the screen in close contact with the window-sash. It would be possible to dispense with the case D and put the screen-roller F directly to the window or door frame; but in this event the roller must be adapted to approach automatically and recede from such frame as the screen is wound up or unwound, in order to maintain the screen in close contact with such frame.

K in the drawings represents a peripheral groove or rabbet in the roller F, to receivethe increased thickness of the screen at the point where the netting and band or the folds of the screen overlap, the object of this being to prevent wrinkling or doubling of the screen at this point, which would otherwise ensue as such screen is rolled up.

. Inlieu of placing the case D at one side of the w-indow and adapting the screen to be stretched laterally across such window or door,

IOO

the ease may be located horizontally across the top or bottom of such door or Window, and adapted to be raised or lowered with respect to the latter.

I do not broadly claim ascreen attached to a spring-roller which is journaled in a removable ease, nor a roller used for sueh purposes having arabbet, K, nora slotted removable cylindrical case for such a roller, being aware that these features are not new; but

Vhat I do claim isl The roller F, having rabbet K, in combination with a exible extensible screen attached to said roller7 and having re-enforcing JAMES IRVING SPEJCER.
