SPECIFICATION forming part of Letters Patent No. 714,669, dated December 2, 1902.

Application filed August 21, 1901. Serial No- 72,732. (No model.)

' window-blinds.

The object of this invention is to produce an inexpensive, convenient, and improved device for closing window-blinds,which is adapted and arranged to be operated from the inside of the window.

The nature of the invention will be fully understood from the following general de-.

scription and the annexed drawings and will be subsequently pointed out in the claim.

Figure 1 of the accompanying drawings is a front elevation of a part of a Window-blind and a portion of the contiguous part of a building with my invention attached. Fig. 2 is a plan view of the same. Fig. 3 is a detail vertical sectional View taken on the line n y of Fig. 2.

In the annexed drawings, A designates the wall of the building, B the window-frame, and F the window-blind.

On the outside of the building to the wall A is fastened the cylinder E, a convenient pedestal E being formed on this cylinder for that purpose. A shaft 1 is journaled in this cylinder and extends a little outside of it at each end. Upon one end of this shaft is rigidly mounted the lever E formed with the extension E Upon the other end of this shaft is rigidly mounted the sheaf-pulley e. Around the shaft 1 and within the cylinder E is wound the helical spring 2. One end of this spring fastens in the shaft 1 at 3, and the other end is fastened inside of the cylinderE at at. This spring is so arranged that it normally holds the extension E of the lever E against the shutter to keep it closed. A cord 1, which works on the pulley e, is conducted under the small pulleys z and over the pulley t to the inside of the building, where it may engage a cleat or other fastenting, as 5.

The lever E is so arranged that the extension E thereof will reach up a little above the lower edge of the window-blind F, whereby when the rope I is released from the cleat 5 the spring 2 will automatically close the shutter. The invention may be employed in connection with any window-blind having means for being automatically opened and held in an open position.

In the drawings I have illustrated a blind which is fastened to the window-frame by the hinge D, which may be held in position by screws or in any other approved and applicable way. In an ordinary two-blind window there are four of these hinges used, one for the top and one for the bottom of each blind.

My invention is applicable for holding the blind in a closed position and in the operation and use thereof.

The various parts are to be first assembled and attached to the proper parts of a window, with the cord I stretched taut and fastened on the inside, as shown in the drawings. Then to close the window-blind the operator releases the cord I inside of the building. This causes the pulley e to turn by the tension of the spring 2, moving with it the shaft 1 and the lever E The extension E engaging the blind, moves it also until it is closed, and it is held closed by the tension of the spring 2. If the operator desires to open the blind, the cord I is again pulled until the lever E is in position illustrated by full lines, Fig. 2, of the drawings. Then the blind can be readily opened by any adaptable means and placed in relative position, whereby the closing device can be used again for shutting it.

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

In a device for closing window-blinds, the combination with the hollow cylinder E, formed with the pedestal E adapted to fasten said cylinder to the wall of a building; and the shaft 1, working in said cylinder, and eXtending beyond the ends thereof; of the spring 2, wound around said shaft, in said cylinder; the sheaf-pulley e, rigidly mounted on one end of said shaft, outside of said cylinder; the lever E rigidly mounted on the other end of said shaft, outside of said cylinder, and formed with the extension E adapted and arranged to engage a Window-blind; the pulleys t' and iny in ventionl have signed my name, in pres i, arranged to engage the cord 1; the cordI, ence of two Witnesses, this 1st day of August, Id arranged to turn the pulley e, and engaging 1901.
