Claims.

This invention relates to shade rollers, and more specifically to a detachable means whereby the conventional roller may be readily adapted for what is generally termed bottom-up shade operation, where the roller is mounted below and the shade is pulled upwardly.

The prime object of the invention is to provide a very simple and inexpensive clip or attachment for holding the upper conventional roller pawl out of engagement with the ratchet.

Another ob-ject is to provide an attachment which can be readily placed in position, and to sc form the roller hub as to accommodate said attachment.

The above and other objects will appear as the specification progresses, reference being had to the accompanying drawing in which I have shown the preferred embodiment of my invention, and in which like reference numerals indicate like parts throughout the several views thereof.

In the drawing- Fig. 1 is an enlarged fragmentary sectional view of a shade roller showing my attachment in place.

Fig. 2 is an enlarged end view.

Fig. 3 is a front view of the notched hub.

Fig. 4 is a sectional edge view.

Fig. 5 is an enlarged perspective view of the attachment.

Fig. 6'is an elevational view showing a shade roller mounted for bottom-up operation.

Referring now more particularly to the drawing in which I have shown the preferred embodiment of my invention, the numeral 5 indicates a standard wood roller, this is. suitablybored as shown at 6 to accommodate the winding mechanism, which includes a spindle 'l having a winding spring 8 anchored to the inner end thereof, a spindle ferrule 9 fits over the opposite end of the spindle, and a conventional spear l@ is mounted in this outer end, and is shouldered as shown at H to accommodate a ratchet and hub l2 and i3 respectively.

A spool bearing l@ is mounted on the spindle ferrule las shown, and a spool l5 is mounted thereon and is provided with laterally projecting ears (not shown), which pierce the end of the roller and which also serve as an anchorage for the end of the winding spring, spaced apart rivets i6 being mounted on the spool, and pawls l1 are pivotally mounted on said rivets and are adapted to engage in the usual manner, this arrangement, however, forms no part of the present invention, the purpose of 1935, SeralNo. 1,511

the description kbeing to show the relation of the winding mechanism to the attachment, so that its function may be readily understood.

The outer .rim of the hub I3 is notched as clearly shown at I8 in Fig. 3 of the drawing, and 5 is adapted to accommodate the leg I9 of the spring clip or attachm nt 20 which is formed as clearly shown in Fig. 5, said clip being formed with 1an opening 2i so that it may be mounted on the spear, the leg being slightly bowed or crimped as shown at 22, so that it resiliently engages the rim of the hub, and when the clip is in position as shown in Figs. l and 2 of the drawing, this leg I9 projects into and covers one of the notches 23 in the ratchet, preventing engage- 15 ment of the pawl with the notch, so that said pawl and ratchet notch are rendered inactive.

In so called bottom-up shade operation, the roller is mounted at the bottom or in any position intermediate the length of the window to permit of ventilation, etc., and it is often mounted adjacent the top ofthe lower sash, an additional shade roller being provided for the lower sash and is operable in the conventional manner (the shade being pulled downwardly), these roll- 25 ers being mounted to overlap to exclude light at that point, consequently, the shade which is mounted for bottom-up operation is operated in an entirely different manner, and the roller pawls must be inactive to permit said operation, and I have therefore perfected practical and i be easily and quickly applied, which standard shade rollers can bottom-up shade operation, or in any other position requiring a single notch shade roller, or a roller having no notches, thereby eliminating the necessity of manufacturing and stocking both single and double notch rollers, as well as the special brackets ofttimes used for this pur- 40 pose, and which permit the permanent disengagement of the pawls once the shade is operated and the pawls become disengaged.

When using a shade roller for this bottomup operation, the spring clip is rst inserted, the roller is manipulated to properly tension the winding mechanism, it is then mounted in the brackets 2li with the live pawl and ratchet notch at the bottom of the roller, and when the shade is operated, the pawl diseng-ages from the notch and .drops downward into inactive position and A ring 25 is usually provided on the end of and an operating cord 21 is ansaid cord leading up and over .55
