SPECIFICATION forming part of Letters Patent No. 405,665, dated June 18, 1889.

Application filed February 16, 1889. Serial No. 302,724. (No model.)

To all whom it may concern:

Be it known that I, MAR UIS L. HALL, a citizen of the United States,residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Devices for Holding the Connecting-Bar of Blind-Stops; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the annexed drawings, in which- Figure 1 is a front view of a portion of a slat-connecting bar of a blind with my improvements applied, and Fig. 2 is a side view of the same.

Before describing the details of construction I desire to say that I am well aware that itis not new to provide a device for holding the connecting-bars of blind-slats so that the latter may be kept in an open position, such devices having been formed by providing a notched strip having a slotted handle and a trigger and a spring-loop secured to the blindframe, so that it may be made to engage the notches in the plate carried by the strip. Another form of device used for this purpose consists of a forked plate secured to the blind and adapted to arrest the downward movement of the connecting bar or rod.

In carrying out my invention I take a piece of spring-wire of a sufficient length and bend it about midway of its length, so as to form an eye E, after which the branches are bent slightly downward and upwardly to form vertical branches D, which are then bent horizontally and outwardly in a semicircular manner to form clamping arms or branches A.

In applying myimprovements to a windowblind I place the vertical branches B squarely against the lower portion of the blind and beneath the slats, and secure the same by means of a screw D, inserted in the eye E. When thus fastened, the curved branches A will assume a horizontal position, with the interspace or aperture between them vertically disposed and at a convenient point to receive the lower end of the slat-connecting bar or rod 0, and thereby hold the same in the desired position.

From the construction shown" it will be seen that I produce a device that may be manufactured at a very small expense, and as the clampingarms A .and the branches B are formed entire and from spring-wire I practically attain a spring or yielding clamp from theeye of the device, so that the whole may be adapted to clamp a slat-bar of any size.

Having described my invention, what I claim is As an ii'nproved article of manufacture, a device for holding the connecting bar or rod of the blind-slats, consisting of a single piece of wire bent midway of its length to form an eye and having upwardly-(Iirected branches B, and a horizontally-disposed clamping portion formed from the branches A, which are bent in a curvilinear manner, the whole be ing adapted to be secured to a window-blind by a screw, substantially as specified.
