WINDOW are Application filed June 10,

This invention relates to improvements in window shade stops.

The primary object of the invention re window casing approximately on the same plane with the meeting lflllS' of the upper and lower sashes to prevent accidental raising of the shade beyond its usual half-way position, the said stops being engaged by the cross strip at the lower marginal edge of the shade.

A further object is the provision of a shade stop through which theside edges of the shade slide during the movement of the shade, and which serves to guide the same during such movement.

A still further object is to provide a shade stop which is simple of construction, inexpensive of manufacture and which can be applied to window casings without marring or tending to detract from the appearance thereof.

With these and other objects in view, the invention resides in the certain novel construction, combination and arrangement of parts, the essential features of which are hereinafter fully described, are particular- 35 ly pointed out in the appended claims, and

are illustrated in the accompanying drawings, in which:

Figure 1 is a front elevational view of a window equipped with my improved shade sto Figure 2 is an enlarged detail vertical sectional view on the line 22 of Figure 1.

Figure 3 is a fragmentary vertical sectional view taken at right angles to Figure 2.

Referring to the drawings by reference characters, the numeral designates a window casing of the conventional type which supports a spring actuated shade roller 11 at the top thereof, and on which the shade 12 is windable. It will be appreciated that 1930. Serial No. 460,173.

ofttimes the shade will accidentally move up- -ward and wind about the spring roller 11,

and which idle rotation tends to reduce the spring tension ofthe roller and which 'requires the removal of its roller from its bracket in order to reset the tension. My invention-aims to prevent the accidental wind- "ing ofthe shade upon the roller and to guide the shade in its sliding movement.

My improved shade stop is designated by the reference numeral 13, and includes a disclike body 14 which maybe constructed of jwood orother like material. The body 14 centrally thereof is provided with an opening 15 for the passage of a fastening element in the nature of a screw or the like 16, whereby the shade stop may be fixedly attached to the inner side of the window casinglO.

Extending outwardly from one ofthe flat faces of the disc like body 14 is an extension 7 portion 17 which is semi-circular in end elevation as best seen in Figure 2 0f the drawings. The extension portion 17 is slotted inwardly as at 18 from its outer end and which slot terminates at the adjacent flat face of the body 14.

In practice, my improved shade stops are used in pairs and are respectively mounted on the same horizontal plane on opposite sides of the window casing 10. In the present in- 30 stance, these shade stops are mounted on a plane substantially the same as the plane of the meeting rails of the upper and lower sashes of a window although they may be mounted adjacent the top of the window cats ing as indicated in dotted lines in F igure 1 of the drawings. After the shade stops have been attached to the window casing by passing the fastening elements 16 through the openings 15 and screwing the same into the' so window casing, the opposite side edges of the shade 12 are flexed and inserted into the slots 18. It will therefore be seen that the shade 12 may have free vertical sliding movement, and be guided in its movement by the walls of the slot 18, and the raising of the shade is limited by reason of the fact that the cross strip at the lower marginal edge of the shaft 12 and indicated at 19 abuts the under side of the respective stops. In Figure w; 1" g r 1,806,373 1 1 it will be noted that the shade cannot pass above the plane ofthe stop'which serves to prevent accidental winding oftheshade upon its roller. If for any reason it should be dejsired to fully wind the shade, the shade may be flexed to move the side edges out of the slotsof the respective stops and then permitted to Wind up. The stop devices as before stated prevent the accidental idle wind- 10 ingrof the shade upon the roller to prevent the roller from losing its-spring tension, and the shade is guided by the walls of the slots 18.

' Having thus described the invention, what I claim as new and desire to secure by Let- 15 ters Patent is f 7 7 1 1.
