2 Claims.

An object of my present invention is to provide a rollscreen assembly of simple construction, which can be readily secured on the exterior of a window frame, the assembly being also durable i and inexpensive to manufacture.

A further object is to provide a rollscreen assembly adapted for mounting on either the casings, blind stops or brick mouldings of a window frame, the parts being so arranged that the assembly can be readily mounted on either one of the mentioned parts of a Window frame without change of any character.

A further object is to provide a rollscreen assembly consisting of a rollscreen casing which has end flanges adapted forsecurement'to the side casings, side blind stops or side brick mouldings of a window frame, and having guides which can also be secured to the members of the window frame just mentioned to receive the side edges of the screen when unrolled from the rollscreen casing.

A further object is to provide means for guiding the side edges of the rollscreen, which means consists of U -shaped guides which are comparatively deep and are adapted to receive the side edges of the rollscreen when in unrolled position.

A further object is to provide a binder bar on the lower edge of the rollscreen which has fiattened ends adapted to travel in the U-shaped screen guides.

Still another object is to provide an inwardly extending finger fiange on the binder bar and to also provide one extending outwardly which can be engaged when the screen is in raised position and where the inwardly extending flange engages the lower edge of the head casing because of the rollscreen casing being mounted against the outer face of the head casing.

Still a further object is to provide novel means for retaining the roller shaft of a rollscreen in anchored position.

An additional object is to provide novel means for supporting a storm sash when my rollscreen is applied to a window frame.

With these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in Which:

Figure 1 is an outside elevation of a rollscreen embodying my invention.

Figure 2 is a vertical sectional view on the line 2-2 of Figure 1, showing the parts on an enlarged scale.

Figure 3 is a. perspective view of one end of the rollscreen casing and the upper end showing a rollscreen guide in separated position.

Figure 4 is a horizontal sectional view on the line 4--4 of Figure 1, showing the parts on an enlarged scale.

Figure 5 is a sectional view similar to the left en d of Figure 4, showing different mounting for the rollscreen guide.

Figure 6 is a sectional view similar to the upper end of Figure 2, showing a mounting for the rollscreen casing corresponding to the mounting of Figure 5.

Figures 7 and 8 are similar to Figures 5 and 6, showing still another installation of the rollscreen assembly.

Figure 9 is an end elevation illustrating a trigger used in connectionwith the rollscreen assem- 75 bly; andv Figure 10 is a sectional view similar to the portion of Figure 2 within the circle 10, and showing how a storm sash is supported relative to a window frame when my rollscreen assembly is ap- 30 plied thereto.

On the accompanying drawings Il have used the reference numeral 10 to indicate a window sill and the numerals 12 and 14 to indicate the side and head jambs respectively of the window 35 frame. The window frame further includes side blind stops 16 and a head blind stop 18.

My rollscreen assembly includes generally a rollscreen casing A, a rollscreen B and rollscreen guides C. The casing A is formed of a back Wall 20, a member 22 forming a top and front wall, and end walls 24. The end Walls 24 have anges 26 spot welded or otherwise secured to the walls 20 and 22 to retain the end walls in position. The end walls 24 are provided with mounting flanges 95 28 perforated as indicated at 30.

Within the rollscreen casing A a shaft 32- is rotatably mounted, although it is normally held in predetermined position by a trigger 34, (see Figure 9). The trigger 34 is pivoted at 36 to the 100 end wall 24 and has a finger 38 adapted to enter a transverse slot 40 in the shaft 32. The trigger however can be swung to disengaged position for rotating the shaft 40 to wind or unwind and thus adjust the tension of the rollscreen spring always provided in connection therewith. A lip 42 is provided on the trigger 34 as an aid to swinging the trigger.

A spring tensioned ,roller 44 is journaled on the shaft 42 and the rollscreen Bis secured to and 110 wound thereon. On the lower edge oi' the rollscreen B a binder bar 46 is provided having fiattened ends 48 and inwardly and outwardly ex'- tending finger flanges 50 and 52 respectively.

The guides C for the edges of the rollscreen each comprise an inner flange 54 and an outer flange 56 constituting a U-shaped guide. 'Ihe flanges 54 and 56 are pressed together as indicated at 58 and perforated at spaced points as indicated at 60. Screws 62 may be extended through the perforations 60 to mount the guides C on the window frame while screws 64 may be extended through the perforations 30 of the rollscreen casing A for mounting it on the window frame.

The particular rollscreen illustrated can be mounted in a variety of ways on the window frame. In Figures 1, 2 and 4 I have shown it mountedron the head and side casings thereof. The rollscreen casing A is first mounted on the side casings 12 and then the guides C are mounted in proper alignment for the edges of the rollscreen B to enter them. Space is left between the edges of the rollscreen and the bottoms of the U-shaped guides C as shown in Figure 4, so as to permit relative expansion and contraction of the window frame without interfering with the proper operation of the rollscreen.

To retain the screen B in lowered position I provide turn buttons 66 mounted by means of screws 68 or the like on the window sill l0. As shown in Figures 2 and 4, these can be turned transversely of the sill when the nger flange 50 is resting thereon and engage the top of the flange so that the spring tensioned screen is thus held in lowered position.

The flange 52 is provided so that when the ange 50 is against the lower edge of the head casing 14, as shown in Figure 10, the flange 52 can be engaged by the operator for starting the lowering movement of the rollscreen which in fact would have to be continued until the binder bar 46 is adjacent the meeting rails of the window sashes, whereafter the flange' 50 could be engaged for drawing the screen down the rest of the way.

With the rollscreen casing and the rollscreen guides mounted as just described, it is possible to still use the ordinary storm sash which ts against the blind stops 16 and 18. In Figure 10 for instance, I have shown the upper end of a. storm sash 68 in position and I have provided for mounting it. Such provision is in the form of a storm sash hook 70 having a perforated ear '72 for securing the upper end thereof to the head casing 14, and a hooked -end '14 with which an eye fitting 76 on the storm sash 68 may coact.

The only difference in the storm sash isthat it must be cut off somewhat at the upper end to permit space for the flange 50. The hook 70 is provided with a lip 78 adjacent the hooked end 74. The lip 78 extends around the lower edge of the front of the rollscreen casing A as best shown in Figure 9. Thus both the upper .and lower ends of the storm sash supporting hook '70 are anchored.

As shown in Figures 5' and 6 the rollscreen may be installed on the blind stops of the window frame. When installed in this manner, the rollscreen casing A of course must be a little shorter and likewise the guides C must be shorter so as to fit within the inner edges of the head and side casings.

Where brick construction is used, the rollscreen may be installed on the head and side .mouldings 80 and 82 as shown in Figures 7 and 8. It will thus be obvious that the rollscreen is designed for a variety of installations and is readily adapted for any one of them. When installed as shown in Figure 2, it does not interfere with the ordinary storm sash generally provided in connection with double sash window frames.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents which.l may be reasonably included within their scope.

I claim as my invention:-

1. For use with a window frame, a casing secured to the head thereof, storm sash hooks secured to said head above said casing and extending therefrom, the lower ends of said storm sash hooks terminating in hooked portions, and means for securing said hooks to said casing adjacent said hooked portions.

2. For use with a window frame, a casing, storm sash hooks extending therefrom, the lower ends of said storm sash hooks terminating in hooked portions, and lips adjacent the hook portions thereof and hooking under the lower edge of said casing for securing said hooks to said casing.

HARRY DIXSON.
