ROLLER WINDOW SCREEN.

Application filed March 6, 1923.

. it appertains to make and use the same.

This invention relates to a roller window screen.

It is aimed to provide a novel construction utilizing a casing applicable in upstanding position adjacent one of the stiles of the window frame and between the sill and lowor sash thereof, adapted to contain a horizontally movable screen, together with means on the casing and. adjacent the free I end of the screen to penetrate said sill and sash and thereby temporarily maintain the screen inoperative position.

Another object is to provide a novel closure plate carried by the sash to coact with the upper edge of the screen, which plate is movably mounted so that it will permit closing of the sash without requiring its detachment therefrom.

A third object is to provide a novel spring control and tensioning means for the screen.

Additional objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings 2- Figure 1 is a view in front elevation showing the screen in operative position applied to a window frame fragmentarily illustrated;

Figure 2 is a vertical sectional view on the line 22 of Figure 1;

Figure 3 is an enlarged elevation of the device alone, partly broken away and in section to disclose details;

Figure 4 is a sectional view on the line ll of Figure 3;

Figure 5. is a fragmentary vertical sectional view through the window frame showing the lower sash in closed position;

Figure 6 is a detail sectional view taken on the line 6-6 of Figure 3;

Figure 7 is a view in front elevation of a fragmentary portion of the window sash and closure plate, and

Serial No. 623,266.

Figure 8 is a sectional view taken on the plane indicated by the line 8-8 of Figure 3.

Like reference characters designate like or similar parts in the diflerent views.

To facilitate an understanding of the invention, a window has been conventionally and fragmentarily shown of which A designates the sill, B the stiles rising therefrom, C the stop strips fastened to said stiles, D a vertically slidable lower sash and E the stool.

In reducing the invention to practice, a suitable casing, preferably metallic is provided as at 10 and adapted for vertical disposition at one side of the window in contact with the stile at said side and with its ends engaging the sill A and lower edge of the sash D, respectively.

Casing 10 consists of a hollow shell 11 provided with a vertical slot or opening 12 at one side thereof through which a. flexible metallic or other screen 13 travels. Adjacent the slot 12, the shell 11 has a substantially straight wall 14 which is adapted for intimate contact against the inner edge of the stool E. At the ends of the shell, caps 15 and 16 are provided and at least one of them is detachable or removable and for instance the cap 16. To this end, cap 16 has 21 depending rim 17 to encircle the exterior of shell 11 and which is provided with inwardly pressed lugs at 18 adapted to snap into openings 19 provided in the shell. The cap 16 being of metal, has certain resiliency which permits yielding or snapping of the lugs 18. Each cap 15 and 16 has an inward- 1y extending sleeve or trunnion 20 and 21, respectively, integral with them which are exteriorly cylindrical or round and extend through end plates 22 and 23 of a roller 24 which is journaled or rotatably mounted thereby. The screen 13 at its inner end as at 25 is fastened to the roller.

A spindle 26 is disposed longitudinally of the roller in a recess 27, with the inner end of the spindle which is round, located in a recess 28 in extension of recess 27 and which is of such size as to permit the spindle to slide therein longitudinally of the roller. The outer end of spindle 26 is square or noncircular as at 29 and normally occupies a similarly shaped non-circular bore 30 provided through the sleeve 21. A shoulder 31 is provided on the spindle to engage the inner end of sleeve 21 and thus prevent outward displacement of the spindle. Within thereof to vary the tension of said spring, and said spring serving to normally maintain said spindle in engagement With said means.

2. A roller device of the class described including a casing having an end provided With an inwardly extending trunnion, a roller Within the casing journaled on the trunnion, said trunnion having a square slot, a spindle within the roller having a square portion engaging said slot and a shoulder engaging said trunnion, a winding spring for the roller secured to the roller and to the spindle, said spindle being slidable to disengage said slot whereby the spindle may be turned to vary the tension of said spring, said spindle being round at its inner end, the roller having a recess to journal said inner end and elongated to provide clearance for sliding movement of the spindle, and said spring normally maintaining said square portion in said recess.

3. A roller Window screen including a casing provided at one end with an angular opening, a roller journaled Within the casing, a spindle mounted Within the roller for endwise and rotary movements with respect thereto and having an angular outer end entering said opening, and a spring con nected to the spindle and roller and yieldingly retaining the angular end of the spindie within said opening.

In testimony whereof I aiiix my signature in presence of two witnesses.
