WILLIAM J. BAKER, OF NEWFORT, AND HARRY A. KONEN, OF CLIFTON, KENTUCKY,

htiitlei ASSIGNOB-S TO W. J. BAKER COMPANY, OF NEWPORT, KENTUCKY, A CORPORATION OF KENTUCKY ROLL-SCREEN notnrne nnvrcn ward movement of the device with which the stop mechanism cooperates. I

Another object is the elimination of hooks, clamps, and the like for retaining a device of the class described in its lowered position.

Another object is the provision of a stop mechanism which is positive in its action and simple in construction and operation.

These and other objects are attained by the means described herein and set forth in the acompanying drawing, in which:

Fig. 1 is a rear elevational view of a conventional window frame with a roll screen embodying the device of this invention;

Fig. 2 is an enlarged view taken on line 22 of Fig. 1;

Fig. 3 is'an enlarged 3+3 of Fig. 1; I

Fig. {i is a detail view of a part of the device, parts being broken away;

Fig. 5 isa view taken on line 5-5 of Fig. 4;

Fig. 6 is an edge view of a nut forming a detail of the invention.

The device of this invention is particularly useful in connection with roll screens and is set forth herein as applied to such a screen. The stop mechanism is adapted to cooperate with both sides of a screen. Inasmuch as the structure is the same on each, the device will be explained as applied to one side only.

The window frame 6 may comprise a casing 7 housing a spring-actuated roll (not shown) to which screening 8 is attached. The screening 8 is normally urged by the spring-actuated roll to an upward or rolledup, non-operative position. Two strips 9 and 10 are secured in spaced, parallel relationship, to the opposed or inner faces of the sides of the window frame 6. Screen-guides 11, extending from the top to the bottom of the frame 6, are positioned in the space 12 beview taken on line tween strips 9 and 10. Guides 11 consist of strips, preferably of metal, joined, as at 13,

along one longitudinal edge, and having the free portions thereof bent. substantially .into L shape so as to provide the spaced, parallel walls 14and15, having rolled edges 16extending outwardly beyond the inner side faces of the window frame 6 to a slightly greater extent than the strips 9 and 10. Thejoined edge portions of guides 11 are positioned and secured beneath thestrip 9; It is not essential that guides 11 be positioned between'strips, such as 9 and 10. The guides I may be attached directly to the exposed side faces of a window without affecting the operation of the device, thus facilitating installation of the screen in windows originally unequipped with'the strips 9 and 10. VJalls 14 and 15 serve as guideways for the side edges of screening 8. A. strip of spring metal '17 curved inwardly of guide 11, is disposed longitudinally against the inner face of walll l,

adjacent the lower end thereof, being secured thereto by its upper end only, which seats in a depression 18 in the wall 1 I I At apoint substantially opposite the midportion of the positioned spring. 17', a-section of Wall 15 is extruded to form a longitudinally extending rib27. Rib 27-is slotted longitudinally' toreceive the shank of a threaded bolt'28 adapted to -be screwed into a nut 29 seated non-revolubly in the interior depression formed by rib'27. Nut 29 is beveled or tapered along its uppermost-edge portion as indicated at 290, Figs. 2 and 6. It is obvious that the bolt and nut may be slidably movedto adjusted positions along the slotted rib' 27.

The lower edge of screening 8 is suitably secured to the rigidmovablebottom strip or bar 19. The ends of strip 19 project into the guides 11, and are provided with bosses or ridges23 adapted to abut the turned-in por tion of'one of'the edges '16 to prevent withdrawal of the positioned strip 19; Flanges 21 and 22 on strip 19 may be provided for facilitating movement of the screen; When the screenis drawn down to its lowered position', the ends of strip- 19pass readily over nut 29 by reason of the bevel 290 thereon. After passing beneath the nuts 29 the strip ends are-urged by spring 17 against the inner.

faces of walls 15 whereupon the tops of ridges 23 come into abutment against the underside of the nuts 29 which serve as stops. The screen is thus prevented from rising until the ends of strip 19 are again pressed against spring 17 whereby ridges v23 are permitted to pass upwardly beyond the retaining nuts 29. It should be noted that the ends of strip 19, in the. lowermost position of the screen, do not pass entirely beneath the lower or free. end of the spring, so that obstruction of or interference between these parts in moving the screen, is avoided. VA fabric strip 25 may be attached to the under side of flange 22 to prevent scratching or marring of the window sill 2.6

The above structure may be slightly modified by omitting the spring 17. In this case the normal inclination of bar 19 in the direction of guide wall 15,. which inclination results from the upward pull of screening 8 on one side of bar 19, is utilized for holdin ridges 23 in contact with the under edges 0 nuts or stops 29. The manualturning of bar 19 upon its longitudinal axis, in the opposite direction serves to bring ridges 23 clear of the one way stops 29, whereupon the screen may be raised.

It may happen in some instances, that the guides 11 are not quite long enough to abut the window sillat their lower ends. In order to close the opening between the screen and the sill that would otherwise result in such an instance, the bolt 28 maybe adjusted downwardly of theslotted rib 27 whereby nuts 29 retain the strip 19in such position that the strip bottom will contact the sill.

What is claimed is 1. In combination, an upwardly-urged screen and a guideway therefor, a strip attachedto the bottom edge of the screen and.

havingan end extending into the guideway, a lateral projection on saidend of the strip and adapted to preclude withdrawal of the positioned strip from its guideway, a spring in the guidewayadjacent the lower end thereof and normally urging-said lateral projection against a wall of the guideway, and abutment means disposed in the guideway adjacent the spring and movable to adjusted position relative to the end of the guideway, said abutment means being adapted to prevent movement of the spring-urged strip end past the abutment until the application of pressure upon the strip overcomes the action of said spring. I

2. In combination an upwardly-urged screen and a guideway therefor, a strip attached to the bottom edge of the screen and having an end projecting into the guideway, a boss onthe end of said strip and adaptinner face of its guideway when the screen is in its lowered position, and an abutment in the guideway upon said inner face and movable longitudinally of the guideway to adjusted positions relative to the end of the guideway, said abutment being beveled on its upper side to permit downward movement of the boss past the abutment and squared on its lowest side to prevent return movement thereof by the upwardly-urging force normally operative uponthe screen.

The combination with an upwardlyurged screen and a guideway therefor, of a bottom strip attached to the lower edge of thescreen-and having an end extending into the guideway, an adjustable abutment in said guideway adjacentthe bottom thereof and disposed above the strip end in the lowered position of the screen, and a projection: on

said strip end extending at substantially right angles therewith and adapted to be held by the upward force'normally operative onthe screen in contact with said abutment when the screen is in its lowered position, movement of the strip on its longitudinal axis serving to permit passage of the projection past the abutment,said projection being adapted to preclude withdrawal of the strip end from their guideway.

4. The. combination 'with an upwardlyurged screen and a guideway therefor, of a bottom strip attached to the lower edge of the i screen and having an end extending into the guideway, an abutment in the. guideway, and.

a boss on the strip end adapted when disposed beneath the abutment, to be held in contact therewith by the upward force normally operative ,upon the screen, said boss being adapted to preclude withdrawal of the strip end from the guideway.

In testimony whereof, we have hereunto subscribed our names this 14th; .day of? January, 1930.
