BOILER WINDOW-SCREEN.

Specification of Letters Patent.

Application filed July 15, 1913. Serial No. 779,127.

-- roller window screens, and consists of a de-- vice whereby screens may be attached to rollers and to each window sash, and automatically wound and unwound as the sashes are raised or lowered. This screen, and the devices operating it, are so constructed and arranged as to keep flies, insects, and small flying particles of any kind from getting into the room, and said devices are so arranged that when the windows are closed said screens are wound up and out of sight. The devices are so constructed that the screens and rollers may be removed at any time to be repaired or replaced, the inside apron or upper casing as the case'may be,

being put on with screws.

One object of my invention is to provide a window screen having a roller and a spring to operate said roller with said screen that shall be both elastic and durable and of sufficient capacity to do the work easily, the same being in proportion to the size of the screen to be controlled.

Another object of my invention is to provide a window screen that shall necessitate the fewest possible changes in the construction and appearance of the window itself either in the frame or sash.

Another object of my invention is to provide a rolling window screen so simple in go--'construction as to be of comparatively small cost, and. one in which all parts are so well adjusted as to minimize the friction and render said screen substantial, durable, and practical.

Other objects of this invention will be apparent as it is more fully set forth.

My invention consists in the construction and combination of its various parts, substantially as will be hereinafter fully described and specifically set forth in the claims.

In the accompanying drawings,-Figure 1 is a perspective View of a window with my screen attached, parts being broken away. Fig. 2 is a front elevation of the roller and spring with the screen removed.

Fig. 3 is a vertical section through the screen at point A, parts being broken away. Fig.

.- Reference being had to the accompanymgdrawings, and to letters and figures of reference marked thereon, which form a part of this specification, l represents a window frame to which my improved window screen is attached, said screen having a metal binding at each end thereof shown at 1 and 1" respectively. 2 is a lower sash to which is attached said screen at points A, C, D. I

3 is a wire screen passing down and behind the window stool 4 and through the longitudinal opening in the sill of window- .frame at 5 and connecting to roller 6 by fastenings shown at 7 and groove 7*. Said fastenings may be screws or any other suitable mode of fastening said screen 3 to roller 6 in connection with said groove 7. Said roller 6 may be made of wood or any other suitable material havinga center shaft as shown at 8 and-8 one end of said roller being turned down and back a distance from the end thereof, as shown at 9, for the pur pose of receiving coiled spring 10, said spring being closely wound and when re-' leased the size of the main portion of said roller 6 and passedover the turned down portion 9 .of said roller 6 and fastened to said roller at inner end as shown at 11. hook-shaped as shown at 12. When the roller and spring are in place below the window frame thisv hook is connected to fastening shown at 13. Said spring is closely wound because each coil represents a certain amount of capacity, the object being to secure the greatest amount of capacity disposed within the smallest space. It is slightly open when the outer end is connected with hook 13, just sufiicient to' allow for expansion lengthwise.

Holder 14 is made of iron or any other suitable material dishing in shape to re- The outer end of said spring 10 is.

of said holder is cut out a segment shown at 17,- for the purpose of allowing fastening 13 to be placed within the circumference of said holder 14 as shown, in Fig. 7 after the same is fastened in its place. This together with circular form and size of holders permits end of screen to. revolve around holders if space for locating roller is limited to the same distance in length as width of window.

Holder 18 is made of iron or any other suitable material of the proper thickness, circular in shape and of the proper size having a hole bored through the center thereof, shown at 19, for the purpose of a bearing into which is inserted center shaft 8*. Said holder 18 having a slot 20 cut through from its outer circumference to and in connection with shaft bearing 19, the same being dovetailed in shape to receive and retain means for holding shaft 8 in bearing 1.9. This slot 20 is for the purposeof inserting shaft 8 into its bearing 19 after said holder 18 has been fastened in its proper place by fastening shown at 21. Into this slot 20 is inserted a stop 22 preferably of metal, for the purpose of retaining said shaft 8 in place in bearing 19 after the same has been inserted therein, said stop being fastened in place by small screu or nail as shown at 23, the inner end of said stop being bent at a right angle to the main portion thereof as shown at 24, the same beingin shape to correspond with slot 20.

Lower sash 2 has a rabbet out along the lower edge thereof shown at 25 for the purpose of receiving metal binding 1 fastened to end of screen 3, there being disposed in said-binding two or more holes 32 and one or more screw bolts 27 according to width of window. At point A'in said sash is a recess 26 cut back a distance to receive nut on said screw bolt 27, thus forming one of the supports for said screen, said bolt also serves to prevent said screen from being drawn down below the window sill when the same is detached from the sash, and also fastens cord 28 to screen binding. This cord is for the purpose of handling said screen 3 when the same is detached from the sash,'and

when not in use-it is tucked between the binding and the shoulder to the rabbet. or if screen is detached between binding and window stool. At point C are turnable hooks 29 which are for the purpose of holding said screen snugly in position against said sash when turned down or releasing the same when turned upwardlyas shown in dotted lines at 30, said hooks being screwed in straight and bent over after they are in place. "At points fi "are pins ,glriven into said sash as shown at 31. These pins are for the purpose of affording additional supports to said screen when the same is placed in position through corresponding holes 32 and the same operated in the same manner as the lower sash.

My device is adjusted and operated as follows:-The screen is tightly rolled on roller 6 and firmly tied. The end of spring 10 is drawn out endwise from end of screen and hook 12 placed on hook or pin 13. Shaft pin 8 is placed in bearing 15, and shaft pin 8 placed in bearing 19 through slot 20. Stop or key 22 is inserted in said slot 20 and fastened securely in position by fastening means 23. The roller is then revolved a sufficient number of times to give the spring 10 the proper tension, the strings are cut. and the upper part of screen 3 and its binding 1 is then passed upwardly through slot 5 in the window sill. The cord 28 and the bolt and nut 27 are then securely fastened in' position as shown in Fig. 3. Holding the screen by cord 28. nut 27 is inserted into recess 26, holes 32 in binding 1 engaging pins 31 at points D. Hooks 29 are then turned downwardly into position and cord 28 tucked into the rabbet in sash 2 and above binding 1*. The screen 3 will now automatically follow sash 2 whenever the same is raised or lowered. It is pointed out that the bolt and nut 27 perform a treble function; 1st. they afford a fastening for cord 28; 2nd, they assist in supporting screen 3 when they are inserted in hole 26; 3rd, they prevent the binding 1 from passing downward through slot 5 in window frame 1 when screen 3 is detached from sash 2. While this screen has been described as being fitted to a lower sash, it may be adiusted to an upper sash and operated in the same way.

Having thus described my invention and the operation of the same. what I claim as new and desire to secure by Letters Patent 1s,
