$PECIFICATION forming part of Letters Patent No. 348,393, dated August 31,1886.

Application filed February 1, 1886. Serial No. 190,337.

To all whom it may concern.-

Be it known that I, BENJAMIN HANDFORTH, of Hoboken, in the county of Hudson and State of New Jersey, have invented an Innprovenicnt in Shade Fixtures, of which the following is a specification.

In window-shades it is usual to connect the brackets for the spring-rollers at the upper ject; but the brackets for the curtain are either complicated and difficult of application, or else separate, and different brackets are required.

My invention relates to compound brackets that are adapted to receive the axes of the spring-roller in the ordinary manner, or to receive such axes in the position necessary to prevent the pawls of the spring-fixture catching into the stationary axis when the curtain is being drawn upwardly.

In the drawings, Figure 1 is an elevation of one of the brackets, and Fig. 2 is an elevation of the other bracket with the axis in position for the curtain to be drawn down. Fig. 3 shows the roller end with the axis in theposition the parts assume when the pawls cease to operate; and Fig. 4 is a horizontal section at the line 00 as, Fig. 2; and Figs. 5 and Gshow the brackets with the axis in the position for the curtain to be drawn up.

The spring curtain-roller is of any desired character. At one endis a circular axis or pin, a, and at the other endis aflattened axis, 1), to pass into the bracket and be held from rotating, so that the curtain will be rolled up by the spring acting between the roller and the stationary axis 1). These parts are of ordinary character, and the pawls c or any equivalent device act between the roller and axle to hold the roller from turning when the parts (No model.)

are at rest. The bracket 6 is made with any suitable flanges and attaching devices at e, and the bracket f is similarly provided with flanges f, for the attaching-screws.

In the bracket f there is the vertical slot or opening for the reception of the flattened axis 7), and when said axis b is placed therein the pawls will act in the usual mannerin stopping the rotation of the spring-roller. \Vhen used in this manner, the round axle or pin a will be in the round portions 2' of the bearings in the bracket 6, and will revolve freely therein. If, now, the curtain-roller is turned end for end, the round axle a will be inserted into the round bottom part, 0, of the slot in thebracket f, and will rotate therein, but cannot escape therefrom, because the round axis is of larger diameter than the width of the upper part of the slot. The flattened axle Z) is to be entered horizontally into the horizontal slot at c in the bracket 6, and in that position the pawls or other devices for stopping the rotation ofthe spring-roller will be out of action, as indicated in Fig. 3, because these pawls can only act when the flattened axis is placed with its longest diameter vertically. It is to be understood that in consequence of the cylindrical axis 1) being of greater diameter than the flattened axis a the opening for the axis a can be made in the sides of the slot that is adapted to contain the axis a, and by having the slot in one bracket horizontal and the slot in the other vertical the brackets are adapted to all the positions in which they can be used, and all that is necessary in preventing the pawls from holding the spring-roller is to place the flattened axisin the bracket that has its slothorizontal. In some cases it is preferable to have the vertical and the horizontal slots in one bracket.

I claim as my invention 1. The combination, with a spring curtainroller having one axis cylindrical and the other flattened, of two brackets having slots, one slot being vertical and the other horizontal, for the flattened axis, and an opening or enlargement forming part of the slot and adapted to receive the cylindrical axis of the roller, substantially as specified.

2. The combination, with the spring ourtain-roller, with a cylindrical axis at one end into action or kept out of action, according to IO and aflattened axis at the other end, of brackwhich of the brackets the flattened axis is in ets for such curtain-roller, each bracket havserted into, as specified. ing an opening, one part of which is adapted Signed by me this 21st day of January, A. 5 to receive the flattened axis and the other part D. 1886.

to receive the round axis, the opening for the I BENJN. HANDFORTH. flattened axis in one bracket standing vertically and in the other horizontally, so that the pawls upon the curtain-roller can be brought Witnesses:
