GUIDE FOR VENETIAN BLINDS.

SPECIFICATION forming part of Letters Patent No. 779,089, dated J anuary 3, 1905.

Application filed January 29, 1904. Serial No- 191,226.

To all whom, it mxty concern:

Be it known that I, FRIEDRICH STERN, a subject of the German Emperor, and a resident of Mannheim, Germany, have invented new and useful Improvements in Guides for Venetian Blinds, of which the following is a specification.

This invention relates to Venetian blinds, and more particularly to the construction of the U-irons in which the blind proper is guided at both sides, which are so constructed that the blind can be brought either entirely or partly into an inclined position, so as to admit air or light to the room.

In the accompanying drawings the improvement is shown. I

Figures 1 and 2 represent in a side View a U-iron in which the Venetian blind is guided, in Fig. 1 with the upper end turned outward and in Fig. 2 with the lower end turned outward. -Fig. 3 shows a U-iron guide separated into two parts hinged together, the upper part being outwardly inclined. Fig. 4 shows a guide with two hinges, so that the upper and lower part of the guide can be turned outward at the same time. Fig. 5 shows in a side view and section the Venetian blind in a straight guide-iron which is shown in Fig. 6 in inclined position. Figs. 7, 8, and 9 show various modes of connection between the several parts of the Venetian blind. Fig. 10 represents, on a larger scale, one of the guides which are shown in Fig. 4:.

At both sides of the window-frame a U- iron is arranged which is connected with the wall by means of elbow-joints 2. Above the U-iron the fixed guide 4 for the Venetian blind proper, 6, is arranged. The fixed guide 4 has an extension 22, hinged at its lower end so that it can bemoved outward with the movable guide 1 when the lower end of the blind is to be turned outward, as shown in Fig. 2. From the extension 22 of the fixed guide 4 a guide-plate 7 extends downwardly, which limits the backward movement of the movable guide 1. The Venetian blind 6 may either, consist of two separate parts, each composed of laths connected by ropes, the two separate parts being connected as hereinafter described, or the rope or band runs through all the laths and around the roller. The Venetian blind 6 after it has been let down can be outwardly inclined at-the top end, as shown in Fig. 1, or at the bottom end, as shown in Fig. 2, by stretching the respective elbowlever 2. The movable guide can further, as shown in Fig. 3, consist of two parts 11 12, which are connected by a hinge 13, in which case a counter-plate 14 is suitably arranged at the upper end of the lower part of the U- iron, projecting upwardly, so as to strengthen the movable guide when in vertical position. The U-iron guide 1 may further, as shown in Fig. 4, consist of three parts 15 16 17, the top and bottom parts 15 17 being hingedly connected to the center part 16. If the blind consists of two parts, then the lower part is suitably made of the same length as the U- iron frame, Fig. 10. Any suitable means may be used for connecting these two parts. Some of such devices are shown in Figs. 7, 8, and 9 as examples. Fig. 7, for example, shows a bolt 19, movable in hasps 20 21 of the two parts of the blind. Figs. 9 and 10 show a lever 27, which is hinged to one part of the blind and has a knob 26 on its inner surface adapted to enter an incision 23 of the other part of the blind. In Fig. 8 a hook 24 is shown, the front part of which is hingedly connected with the other part, which is fastened to one part of the blind, the front part being adapted to grip over a pin 25, fixed on the other part of the blind.

The hereinbefore-described construction of blind and guides may be modified as shown in Figs. 5 and 6. There is only one elbow-joint 2 provided at the bottom end of movable joint 1, which is used for turning outward the lower end of the blind, as described. If the upper end of the same is to be turned outward, the bands 23, connecting the laths of the blind, replace the upper elbow-lever, as shown in Figs. 1 to 4:. With this construction the blind proper consists of one part only, which is connected with the roller by means of the bands 28.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. An improved guide for Venetian rollerblinds comprising in combination two movable U-irons one at each side of the window-frame, two elbow-levers hinged to the window-frame and to the U-iron at the top and bottom ends respectively, a fixed guide rigidly fixed to the window frame above the movable U-iron guide, an extension of the fixed guide hinged at the front surface to the bottom end of said fixed guide, a plate downwardly projecting from the inner surface of said extension, substantially as described and shown and for the purpose set forth.

2. An improved guide for Venetian rollerblinds comprising in combination a movable U-iron composed of two parts hinged at their front surface, two elbow-levers hinged to the window-frame and to the U-iron at the top and bottom ends respectively, a fixed guide rigidly fixed to the window-frame above the movable U-iron guide, an extension of the fixed guide hinged at the front surface to the bottom end of said fixed guide, a plate downwardly projecting from the inner surface of said extension, substantially as described and shown and for the purpose set forth.

3. An improved guide for Venetian rollerblinds comprising in combination a movable U-iron composed of three parts hinged together at their front surface, two elbow-levers hinged to the window-frame and to the U-iron at the topand bottom ends respectively, a fixed guide rigidly fixed to the window-frame above the movable U-iron guide, an extension of the fixed guide hinged at the front surface to the bottom end of said guide, a plate downwardly projecting from the inner surface of said extension, substantially as described and shown and for the purpose set forth.

4:. An improved guidefor Venetian rollerblinds comprising in combination two movable U-irons one at each side of the window-frame, an elbow-lever hinged to the window-frame and to the bottom end of said movable guide, a fixed guide rigidly fixed to the window-frame above the movable U-iron guide, an extension of the fixed guide hinged at the front surface to the bottom end of said fixed guide, a plate downwardly projecting from the inner sur face of said extension, substantially as described and shown and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit-' nesses.
