WILLIS F. HOLSTEEN, OF CHICAGO, ILLINOIS.

SHADE STOP AND PROTECTOR.

Specification of Letters Patent.

Patented Aug. 26,1913.

Application filed July 27, 1912. Serial No. 711,811.

To all whom it may concern:

Be it known that I, WILLIS F. I'IOLSTEEN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Shade Stops and Protectors; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numbers of reference marked thereon, which form a part of this specification.

In the use of spring curtain or shade rollers, the curtains or shades have frequently been injured (sometimes beyond repair) by the winding up of the curtain when the spring is tensioned excessively, so that the lower end of the curtain or shade, with its roller, is frayed or injured by beating against the head jalnbor stop of the window. Much inconvenience also is occasioned by the curtain cord or pull, in such cases, winding many times around the roller, thus inconveniencing the householder, and, in some instances, rendering it diflicult to again draw the shade.

The object of this invention is to afford a construction whereby the rolling or winding up of the curtain is stopped at the moment that the curtain is wholly or sufiiciently wound upon the roller, thereby preventing the lower edge of the curtain being whipped around the roller.

It is also an object of the invention to afford a construction whereby the curtain may be either supported at the top of the frame, or at any desired height therein, and suitable stops employed to limit the winding up of the shade to full opening.

The invention (in a preferred form) is illustrated in the drawings, and hereinafter more fully described.

In the drawings: Figure 1 is a central, vertical section taken through a window frame, the sash, and the shade roller and shade therefor, and showing the shade roller mounted on the inner casing for the frame. Fig. 2 is a similar View, showing the shade roller mounted in the frame and on the inner window stops. Fig. 3 is an enlarged, fragmentary detail of the construction illustrated in Fig. 2, showing the shade roller journaled near the top of the window frame. Fig. 4 is a similar view, showing the shade roller journaled somewhat lower in the window frame, or at any desired height therein. Fig. 5 is a fragmentary face view of the construction illustrated in Fig. 4;. Fig. 6 is an enlarged, sectional detail of the lower margin of the curtain and the curtain stick, with a protector embodying my invention mounted thereon and shown in full lines.

As shown in the drawings: 1, indicates the jamb of the window frame, and 2, the inner side stops; 3, the inner head stop; a, the ordinary or usual automatic spring shade rolle 5, the curtain, and 6, the usual or ordinary lower curtain stick. Mounted on the shade roller near each end thereof, on the outer side of the shade, or that adjacent the sash, are protectors embodying my invention, any desired number of which may be used. As shown, said protectors comprise each a stop rigidly secured to the curtain stick and extending well above the same and adapted to arrest the further rolling of the shade upon the curtain roller by the engagement of the head of the stop either at the top of the window frame or upon a suitable stationary stop therefor. Said stops, of course, may be constructed of any suitable material or in any suitable manner. Conveniently, however, I have constructed the same of nickel plated steel wire, of suitable gage, near one end 7 of which, it is bent to afford a loop to receive the screw or bolt 8, whereby the same is secured upon the stick, and the extremity of said bent end is turned backwardly and afiords a sharp hookor spur to engage through the curtain, and in the upper edge of the stick, as shown in Fig. 6. Beyond said loop, and a sufficient distance above the stick, said wire is bent outwardly at a right angle, and thence downwardly and inwardly, affording a brace rod 9, which engages the stick within the loop, as shown in Figs. 5 and 6. Conveniently, a short section of rubber pipe 10, is secured upon the upper or bent portion of the stop to afford a resilient contact when engaging the stationary stop. v

If the curtain or shade roller is j ournaled on the inner casings of the frame, as shown in Fig. 1, and near the top of the frame, said stop or protector, of course, will strike against and engage the inner head stop, as shown in Fig. 1, when the curtain is fully rolled up, and thus prevent further winding of the curtain, and injury thereto. If on gaged substantially at the top of the window frame, and on the inner stops thereof} as shown in Figs. 2 and 3, further winding of the shade roller is arrested by the engagement of the protector or stop against the inner head stop 3, of the frame.

To prevent any possibility of said protector or stop swinginginto the space between the roller and the head stop, a stationary stop 1O comprising an angle plate having the flange positioned to afford a stop for the top of the protector, is screwed to the head stop, as shown in Figs. 2 and 3. Should it be desired, however, to journal the curtain roller sufficiently below the top of the frame, to otherwise permit said protector or stop to pass over the roll, stationary stops, each comprising a vertical flange 11, and a horizontal web 12, and having a flange 13, at one end thereof for engagement with the stop, is secured upon the inner side stops of the window in position for the heads of said protectors to be engaged in the angles formed by the web flanges to arrest the further winding of the shade upon the roller, as shown in Figs. 4; and 5. Of course, with this construction,

.the roller may be placed at any desired height in the frame, with the certainty of properly limiting the rotation of the roller to just sutficient to wind up the curtain or shade.

The operation is obvious from the coni f struction described in the foregoing specifidictate.

cation. It is to be understood, of course, that the stationary stops may not always be required, and if required, may assume various forms as convenience and taste may It is also to be understood that the protectors mounted upon the shade may be constructed of any suitable material, or inany suitable manner, and may be of any suitable form or configuration, ornamental or otherwise.

'1 suggest themselves.

I have shown but a preferred construction embodying my invention, although numerous variations and modifications, both in construction and arrangement, will readily I therefore do not purpose limiting the patent granted on this application, otherwise than necessitated by the prior art.

I claim as my invention:

1. The combination with a spring curtain roller and its shade, of a resilient shade stop and protector carried on the outer lower margin of the shade, and projecting upwardly and outwardly therefrom and adapted to limit the winding up of the shade by engagement with a fixed stop secured to the window frame.

2. A shade protector and stop comprising a substantially triangular bracket secured to the window shade at its lower margin and projecting upwardly therefrom, a fixed stop for engagement thereby, and a resilient head on said shade protector and stop adapted to absorb shock when engaging the fixed stop.

3. A device of the class described comprising a wire bent to afford a bottom attaching loop, and a spur or hook adjacent thereto, an elongated head above said loop and hook, and a resilient covering on said head.

4. The combination with an automatic spring shade roller, the shade and bottom stick in the shade, and the frame in which the shade roller is journaled, of a shade T ried on the outer side of the shade and the shade stick, a resilient head on each of said protectors, and supporting stops engaged to the window frame and projecting over and adjacent the roller and adapted to be e11- gaged by the heads of said protectors when the curtain shade is fully wound up upon the roller.

In witness whereof I have hereunto subscribed my name in the presence of two N subscribing witnesses.

WILLIS r. HOLSTEEN.
