ROLLER FLY-SCREEN.

Specification of Letters Patent.

Patented May 23, 1916,

Application filed June 5, 1915. Serial No. 32,300.

To all whom it may concern:

Be it known that 1, WILLIAM C. G. PETER,

a citizen of the'Dominion of Canada, residing at Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Roller Fly- Screens, of which the. following is a specification.

This invention relates to a window fly screen of that class wherein the gauze screen is mounted ona roller which is rotatable within an inclosing casing adapted 'to be removably secured across the top of a w1ndow frame on the inner or room side.

The invention comprises the general construction of the screen and the manner of mounting the same that it may effectively exclude flies from a room when applied to the inside of a window for use with aslidable or a casement sash, and can be conveniently rolled up from the inner or room side and is self-sustaining in either the open or the closed position.

The particular features to which attention is drawn are the attachment of the roller casing to the inner facing of the wmdow by which the roller winding cord or line may depend directly from the roller on the inside of the window sash, the provision of a flexible fly excluding flap depending from the upper edge of the roller casing and weighted to bear against the outer side of the blind onthe roller, the means whereby the closure of the lower edge of the screen on the window sill is effected, and the provision enabling the blind to be applied to a casement window havlng an opening and securingbar.

The invention is particularly descrlbed 40 in the following specification, reference being made to the drawingsby which it is accompanied, in which:

Figure 1 is a perspective view and part section showing the application of the screen v dow, and Fig. 2, a longitudinal section on the line A in Fig,

In these drawings 2 represents th inner facing of a window frame, 3 the Window 5111 and 4 the sash, which is hinged as a case- 60 ment and is secured in any desired position of opening by a bar 5 hinged at 6 to the lower rail of the sash and is endwise slidable and securable in a sleeve 7 which is pivotally mounted on the Slll.

66 Removably secured n any convenient manner to the inner facing of the window to a casement win screen from the window,

frame. It is adapted cle of the roller.

frame is a sheet metal casing 10 formed as a segment of a cylinder. The ends of, this casing are flanged.outward, as at 11, toward the open segment of the casing, and these outwardly flanged ends form the means for attachment to the inner facing of the window. Attachment is here shown as made by means of wire cleats 12 secured in the windowU facing and susceptible of being turned outward, as indicated in Fig. 2, for removal of the casing and its contained when not required, as during the winter months.

In the ends of the casing 10 a roller 13 is rotatably mounted by means of axial end pins 14:. One of these end pins is screwed into the end of the roller from the outside to facilitate introduction of the roller or its.v

removal from the casing. On this roller is secured a wire gauze screen 15 on the free end of which is secured a strip 16 of aweight sufficient to draw the screen flatly out when it is unwound from the roller.

One end of the roller extends a short dis tance beyond theadjacent edge of the screen secured to it, and is flanged to retain on it a cord or other flexible connection 17 One end of this cord is secured to the roller, around which it is coiled in an opposite direction to the screen, and the free end of 17 is passed through an eyelet 18 and has a weight 19 secured to it sufiicient to insure that the cord winds closely on the roller.

Each side edge of the screen-15 moves in a groove 20 provided on each side of the window frame, which groove may be formed by a strip of metal or a rabbeted strip 21 of Wood, To enable the lower edge of the strip 16' of the screen to form an effective closure on the sill of the window, when the screen isdrawn down, the strip has secured to it adjacent the attachment of the screen, a covering 22 of leatherette or other suitable flexible fabric, the loop 23 of which rojects beyond the lower edge of the strip. his free loop .will adapt itself to slight inequalities in the surface of the sill 3.

To prevent flies crawling up the outside of the screen fromobtaining entrance to the room around the inside of'the casing 10, a flap or short curtain 24 is suspended from a rod 25 extending across between the ends of the casing above and slightly within the cir- The lower edge of this curtain is weighted with a rod 26 threaded through it which will hold the curtain against the screen of the roller and will.

prevent entrance ofthe flies. The upper edge of this curtain projects, as at 27, above the hem through which the suspension rod is passed' so that it will-effect a closure between it and the inside of the casing, or the flap 24 may be connected direct to the upper edge ofthe casing.

Where the screen is applied' to a casement window, as shown in the drawing, provision is made to enable its strip to pass over the bar '5 by which the window is secured'in the open position; As the position of the rod 5.' angulanly 'changes across the width j of the window according to the amount the window is opened, the strip 16 is formed of folded sheet metal, as shown in the drawing, and agap 28-is cut from the lower edge upward corresponding in length to the extreme angular range in the position of the securing bar 5, and slidably fit ting on the fold of the strip 16 is a correspondingly bent strip 29, which is provided with agap 30 corrtsponding to the diameter of the .bar 5. The gap 30 may thus traverse laterally across the width of the blind within the range required. The slidable strip 29 may be covered with fabric which of the gap to form a more effective closure in its adaptation to may be slit in'the middle the securing bar 5. 7

As the bar 5 is usually above the level of the sill a shutter 31 having an outwardly turned finger engagement is slidable within l the member 29' and is of such depth that I it will close the gap 30 beneath the bar after the screen is drawn down to the sill. This shutter 29 is shoulderedas at 32, so that by moving it further across, the gap 30 may be entirely closed, when not required. 1

A simple \roller fly screen isthus provided that may be applied to the inside of awindow having either a lifting or a casement sash and having provision both along its the screen is sufficient to hold it position and requires no fastening such as 1s necessary when the screen is wound on a sprlng actuated roller.

I am aware that prior togmy invention w roller screen blinds have been used for this purpose'but they have commonly been applied outside the window sash in which position they are not only more exposed to the weather and therefore more liable to dea window frame,

. ing attached adjacent the structive corrosionbut such cannot be applied to casement wlndows,

and. the lifting means, where such is used,

cannot be con- -veniently conveyed to within the room. Nor' am I aware of any blinds being furnished with means to effect satisfactory closure on the sill, nor with the curtain or flap closing access around theroller. casing.-
