WINDOW-SHADE PULL.

Specification of Letters Patent.

Patented Sept. 26, 1905.

Application filed December 14, 1903. Serial No. 185,071.

To all whom it may concern.-

Be it known that we, HARRY N. HERR and ABRAHAM LINooLN MoYER, citizens of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in \Vindow-Shade Pulls, of which the following is a specification.

Our invention has reference to shade-pulls; and it consists of features fully set forth in the following specification and accompanying drawings, forming part thereof.

The object of our invention is to provide a shade-pull for window-shades of neat appearance, cheap to construct, and effective in accomplishing the object of its design, the purpose being to maintain a firm grip on the shade-stick and shade, to be readily applied and easily removed,and yet neither application nor removal will in any way injure the shade fabric.

It is our purpose in practice to have a cord depend from the pull as a matter of convenience for shade manipulation; but we of course do not limit ourselves to the use of the cord.

It consists of a metallic blank of resilient material formed of a shape suitable to engage the shade-stick on its two sides. The parts of the blank that become shade-engaging carry one or more shade-lugs, which are preferably struck up from the body of the metal and are therefore integral therewith. These lugs contact with and are held to the shade by impinging embrace by an internally-threaded sleeve passing through one side of the said formed blank coacting with a screw which engages with the said sleeve after passing through the other side of the formed blank, a suitable hole for screw passage being provided in the said latter side of the formed blank. The screw and the sleeve thus become a looking means for the two lateral arms of the pull (lateral after forming) and give us an effectual means for drawing the pull in close impingement with the shade-stick and shade. It will be apparent that the sleeve becomes locked against rotary motion by virtue of the shape of the hole in the side of the pull through which it passes, as the outer contour of the sleeve conforms to the shape of the said hole. The sleeve thus cannot turn, and the turning of the screw draws the lateral walls of the pull in close engagement with the shade and the shade-stick, and thus they are held.

In the drawings like parts are referred to by marks of a corresponding kind in the different views.

Figure 1 is a side view of shade with our device applied. Fig. 2is a vertical section of the stick and an end view of the device, being a section of the line 1 X 2 of Fig. 1 looking in the direction of the arrow 0 Fig. 3 is a side view of the side of the formed blank looking in the direction of the arrow 0 and showing a preferred shape for the locking-hole in the said side. Fig. l is the opposite side of the said formed blank, showing the coinciding screw-hole whereby the'screw is retained in alinement with the sleeve hereinbefore referred to and for the purposes already stated. Fig. 5 is a side view of the sleeve enlarged; Fig. 6, an end view, and Fig. 7 a section on the lineX X of Fig. 5. Fig. 8 is a longitudinal section of the sleeve; and Fig. 9 is the screw which coacts with the sleeve, as and for the purpose hereinbefore set out.

A is the curtain.

B and C are the lateral walls of the shadepull after forming.

I is an indented portion of the pull where the sides of the blank are bent upward. d is a hole in this portion of the device for the reception of a cord, as shown in Fig. 4:, also in Fig. 1.

ff are lugs integral with the body of the pull, and they are the shade-impinging elements.

0 is a rectangular hole in the side B of the pull, and it is the rectangular body of the sleeve which is retained by the said hole, the latter fitting snugly into the former. We do not, however, limit ourselves to a rectangular shape for this hole. Any shape that will arrest the turning tendency of the sleeve will fulfil the purpose of our design.

The hole WV in the side C of thepull carries the screw J, and when the parts are assembled the said screw and sleeve are in alinement, as shown in Fig. 2, also Figs. 8 and 9 The said screw and sleeve are pulled together or drawn apart by the turning of the screw.

i is the threaded hole in the sleeve, with which the screw engages.

The cord H can pass through the hole (Z or around it and over the arch 1.

Having now described our invention, What we claim as new, and desire to secure by Letters Patent, is

arm in alinement with the said sleeve, thus forming a locking means between the two arms whereby the said arms are held in look- :ing embrace with the shade-brace and shade, as and for the purpose set forth.

In testimony whereof we afiix our signatures in presence of two Witnesses.
