Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed May 1, 1905. Serial 110- 258,415.

To (til whom, it may concern:

Be it known that I, FRANOENIA FoLDnN, a citizen of the United States, and a resident of Beatrice, Nebraska, have invented certain new and useful Improvements in Window- Screens, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates towindow-screens, and has for its object the provision of a simple, inexpensive, and easily-operated windowscreen that is adapted to roll up in a housing at the top of the window-frame, and which screen when lowered to cover the window will very effectually prevent the passage of flies and other insects through the window.

To the above purposes my invention consists in certain new and novel features of construction and arrangement of parts that will be hereinafter more fully shown, described, and claimed.

In the drawings, Figure 1 is a front elevation of a window equipped with my improved screen. Fig. 2 is a vertical section taken on line 2 2 of Fig. 1. the upper right-hand corner of a window provided with my improved screen, parts thereof being broken Fig. 4 is an enlarged detail section taken approximately on the line4 4 of Fig. 1. Fig. 5 is an enlarged horizontal section taken approximately on the line 5 5 of Fig. 1, parts thereof being broken away. Fig. 6 is a detail elevation of one of the levers made use of for manipulating the binderstrips that engage the side edges of the window-screen. Fig. 7 is a perspective view of a bracket I make use of in carrying out my invention. Fig. 8 is an enlarged vertical section taken approximately on the line 8 8 of Fig. 1. Fig. 9 is an end elevation of the housing in which the wire screen is rolled at the top of the window, a portion of said housing being broken away to show the parts on the inside thereof.

Referring by numerals to the accompanying drawings, 1 indicates the window-sill, 2 the upright side pieces of the frame, and 3 the cross-piece at the top of the frame. Located at the outside of this cross-piece 3 and held in any suitable manner is a housing 4, preferably formed of sheet metal, and there being a continuous opening or slot 5 formed in its lower edge, next to the cross-piece 3, through which passes the window-screen.

Located just inside of the housing 4 and Fig. 3 is a front elevation of secured in any suitable manner to the crosspiece 3 are outwardly and upwardly projecting brackets 6, that support the sliding bearing-plates 7, in which the ends of an ordinary spring roller 8 are journaled. These plates 7 are free to slide backward and forward on the brackets 6 as the screen winds and unwinds from the roller 8, and in order to form a tight joint between said screen and the crosspiece 3 I locate an angle-bar 9 within the housing 4 against the cross-piece 3, the ends of which angle-bar bear against the face of the cross-piece. This particular location of the angle-bar 9 and the arrangement of the brackets 6 permit the screen in rolling or unrolling upon the roller 8 to bear against the under side of said angle-bar 9.

Located at the outside of the inner edges of the upright pieces 2 are the channel-guides 10, in which travel the side edges of the windowscreen 11, which latter is secured to and winds upon the roller 8. These channel-guides 10 are held in position by brackets 11, that are socured to the side pieces 2 of the window-frame and which have their outer ends bent outwardly from said channels 10 and then bent at angles relative the plane occupied by said guides, as indicated by 12. Binder-strips 13 are positioned adjacent the open edges of the channel-guides 10,and in said strips are formed inclined slots 14, through which pass the bent ends 12 of the brackets 11. The inner edges of the binder-strips 13 travel across the open ends of the channel-guides 10 and bear against the side edges of the screen that ispositioned in said channel-guides, and by reason of the angularity of the ends 12 of the brackets 11 and the inclination of the slots 14 the binder strips 13 travel away from the side edges of the screen when said strips are elevated and toward the edges of said screen when said strips are lowered.

Rigidly fixed to the lower end of the screen 11 is the transversely-arranged metal binderstrip 15, the ends of which travel in the channel-guides 10. A wooden strip 16 is secured to the lower end of the metal-binder-strip 15, which wooden strip is adapted to lie immediately upon the sill 1 when the screen is lowered to its limit of movement. The lowerinner corners of the binder-strips 13 are cut away, as indicated by 17, in order to fit over the ends of the strip 15 when said binderstrips are drawn downwardly and inwardly.

The devices for imparting movement to the binder-strips 13 comprise a pair of rock-shafts 18, journaled in bearings 19, fixed to the sill 1 adjacent the sides 2, and the inner endsof said rock-shafts 18 are bent upwardly, as indicated by 20, the upper ends of which portions terminate in' handles 21. The outer ends of the rock-shafts are bent upwardly and outwardly toward the lower ends of the binder-strips 13, and links 22 are pivotally connected to the upwardly and outwardly bent endsof said rock-shafts and also to the lower ends of the binder-strips 13.

The wooden strip 16is provided with suitable apertures 23, through which pass the upwardly-bent ends 20 of the rock-shafts 18 when the screen is lowered and said wooden strip is bearing upon the sill 1.

When my improved window-screen is in use, it is lowered so that it covers the entire window-opening, and thewooden strip 16 is brought to bear directly upon the windowsill 1. The handles 21 of the rock-shafts 18 are now engaged and said rock-shafts so rotated as that the binder-strips 13 will be drawn downwardly and inwardly to engage the side edges of the screen 11, and thus a tight jointis formed all round the window-frame and insects are thus effectually prevented from passing through the window so screened. When it is desired to elevate the screen for any purpose, the handles 21 are engaged and manipulated so as to elevate the binder-strips 13, thus moving their edges away from the edges of the screen, and the spring-roller 8 now automatically rotates and the screen 11 is wound thereupon. As the screen winds upon said roller said screen will bear against theangle-bar 9 and said roller will gradually Inove outward away from the top piece 3 and in so doing the bearing-plates 7 will gradually slide outwardly upon the brackets 6.

The movements of these parts will naturally reverse when the screen is pulled downwardly.

The window-screen of my improved construction is very simple and efiicient and when in use very effectually prevents the passage of insects through the window and either sash of the window may be raised or lowered to secure perfect ventilation.

It will be noted that the handles 21 of the rock-shafts 18 are inside the window-screen. and therefore the release of the binder-strips 13 is accomplished from the inside of the house. When these handles are shifted to bring the binder-strips 13 downwardly to tightly engage the edges of the windowscreen, said arms 20 bear on the strip 16 and cause the same to closely engage against the sill 1.

I claim 1. A window-screen, a roller held for rotation and for movement to and from the top of a window-frame; an angle-bar secured to the top of the window-frame adjacent said roller; a housing inclosing said roller and angle-bar; a screen fixed to and winding upon said roller; channel-guides fixed to the window-frame in which the edges of the screen travel; binder-strips held for vertical and lateral movement at the front edges of said channel-guides, and means whereby said binderstrips are moved vertically and laterally, substantially as specified.

2. In a window-screen, a roller arranged for rotation at the top of a window-frame, a screen fixed to wind upon said roller, channel-guides fixed to the window-frame in which the edges of the screen travel, binder-strips held for vertical and lateral movement at the front edgesof said channel-guides, bell-cranks journaled to the sill, and links connecting the ends of said bell-cranks with the lower ends of the binder-stripswhereby said strips are elevated and lowered by manipulating the bellcranks; substantially as specified.

In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
