ROLLING SCREEN.

Specification of Letters Patent. Patented Dec. 28, 1920.

Application filed November 19, 1918. Serial No. 263,175.

and State of Ohio, have invented new and useful Improvements in Rolling Screens, of which the following is a specification.

As its principal object, the invention seeks the provision of a rolling screen extensible as regards its width so that it may be attached to various widths of window frames.

A further purpose of the invention is the provision of a unique extensible roller and shield therefor on which the screen is carried and further the provision of a unique extensible bottom rail for the screen.

As a still further purpose, the invention seeks the provision of a device of this character which is comparatively simple in construction, durable and effective in operation and inexpensive to manufacture.

To the exact construction in which it is shown and described, the invention is not to be restricted. The right is reserved to make such changes or alterations as the actual reduction to practice may suggest, in so far as such changes or alterations are com prehended in spirit by the annexed claim.

The same numerals of reference designate the same parts throughout the several figures of the drawings, wherein:

Figure 1 is a perspective view of a window frame equipped with the improved screen.

Fig. 2 is a longitudinal sectional view through the'roller and the housing therefor. F Fig. 3 is a section on the line 33 of FFig. 4 is a section on the line 44 of Fig. 5 is a perspective view of one of the screen roller supporting members.

Fig. 6 is a perspective view of the cooperating screen roller supporting member.

Fig. 7 is a perspective view of the bottom rai Referring to the drawings, there is shown in Fig. l a window frame in which the view is from the inside, the frame being provided with the usual upper and lower sash 1 and 2 of which the latter slides between'the usual beads 3 and 4:. The invention is shown as attached for screening the upper part of the window when the sash thereof is lowered. For screening the lower half, closed by the bottom sash, a screen identical with that shown in Fig. 1 is employed when it is positioned on the outside of the lower sash so that it has the same relative position with reference to the upper sash that the screen herein has with reference to the lower sash. It is for the purpose of illustration only that the screen is shown applied as herein illustrated.

The improved screen comprises a roller composed of two telescopically connected tubular members 5 and 6. The former at the end remote from that which connects with the latter is closed by a disk 7 set in from the end. This disk 7 is provided with a central hole to permit its engaging forrotary movement thereon the stud 8 emanating centrally from the side of a disk 9 bounded on its peripheral edge but on the same side with the stud by the flange 10. This flange,

however, is not continuous, an open space 11 being provided at a prescribed point on its periphery. The disk 9 and its attendant parts just mentioned provide the supporting means for the roller and its shield at one end, and therefore is provided with the depending member in the form of a flat plate" 12 through which suitable screws may pass to attach the disk to the head 4. A cooperating supporting member is provided in the form of a second disk 13 having the plate 14 and the eripheral flange 15 which are identicalwith the equivalent parts on the disk 9, all of reverse position as respects the latter.

Instead of the short stud 8, however, the disk 13 is provided with a relatively long stud 16 emanating from that face on which the flange 15 stands but this stud 16 carries at a point in close proximity to the disk 13 a collar 17 which is fixed against either rotary or longitudinal movement on the stud.

Set within the section 6 of the roller, there is a collar 18 provided with a central hole in which the end of the stud 16 is journaled when the roller is mounted, as shown in Fig. 2.

The two sections 5 and 6 have struck from their outer surfaces the prongs 19 by means of which the sections 20 and 21 of the screen are attached to the roller, the former section to the section 5 and the latter section to the section 6, the prongs being pushed down to the surface of the roller after the screen sections are attached. Since the section 5 is telescoped over the section 6, some means must be provided to permit the ad acent longitudinal edges of the screen sections to pass each other as the length of the roller is adjusted to increase or decrease the width of the screen as a whole and this means comprises a longitudinal slot 22 cut in the section 5 for a specified length fromthat end through which the section 6 enters. This provides space through which the screen section 21 may pass as the two sections of the roller are adjusted for the width of the window frame as previously described. The screen is designed so that it will normally roll up and this rolling up tendency is provided in the form of a spiral spring 23 which surrounds the stud 16 between the collars 18 and 17, having each end fixed to one of the said collars. Since the collar 17, being mounted with the disk 13 and its stud, is stationary and the collar 18, being mounted with the roller, is movable the unrolling of the screen effects relative rotary movement between the collars17 and 18 with the result that a torsional strain is exerted on the spring 23. Thus when the force which accomplished the unrolling operation is removed, the spring resumes its former condition with the result that the roller is reversed in the direction of rotation and the screen thereby wound up The extreme edges of the roller, when the latter is mounted in its supporting members, be close but do not touch the disks 9 and 13 and since the screen is connected to the extreme ends of the roller, the. screen lies close to these disks and would not be permitted to roll and unroll from the roller, were not the open spaces provided in the flanges 10 and 15. These open spaces just referred to as being in the flanges, are so positioned with respect to the disks that the screen passes through them just prior to its wlnding on the roller, that is the screen before it begins to bend preparatory to winding on the roller has passed through these open spaces in the flanges.

The screen when attached to a window sash has the roller and the coiled part of the screen housed in a tubular member composed of telescoping sections 24; and 25, both of which are provided with longitudinal slots 26 which register with the openings 11 in the flanges 10 and 15. The sections 24 and 25 of the housing member are supported by the said flanges, they being open is claimed as new an insane and of such dimensions as tosit within and frictionally engage the said flanges.

The bottom edge of the screen to protect it, connects the bottom rail composed of telescoping sections 27 and 28 to which the lower edges of the screen are suitably connected respectively.

It will be observed that the length of the roller, the. bottom rail, and the housing may be increased or decreased to suit the breadth of the window on which the screen is attached, the attaching of the disks 9 and 13 by suitable screws, as before said, serves to support the screen in the said window frame. As the screen is for screening the upper part of the window, as shown, the hook members 29 may be attached to the top rail of the upper sash and made to engage the bottom rail of the screen. If the screen is used for the lower part of the frame, th means of attachment are reversed, the screen being mounted at the bottom of the frame and outside the. bottom sash, and the latter carrying the hooks 29 with which the bottom rail of the screen is engaged.

From the foregoing description and the accompanying drawings, it is believed that a clear enough understanding of the invention will be had to render further description unnecessary.

The invention havin been described what useful is:

A screen of the character described comprising a hollow telescoping sectional roller, supporting elements for said roller one of which is provided with a relatively short laterally projecting stud on which one of the sections of the roller is journaled, the other supporting element being provided with a relatively long laterally projecting stud entering the other section of the roller, a disk fixed on the latter stud and loosely engaging I the inner periphery-of the attendant section of the said roller, a second disk fixed in the said .section of the roller and rotatably mounted-on the said latter stud adjacent its extremity, and a spring in surrounding relation to the stud between the two disks and fixed one end to each, whereby a rolling up tendency is provided for the purpose specified.

In testimony whereof I aflix my signature.
