Letters .Patent No. 95,993, dated October 19, 1869.

The Schedule referred to in these Lettera Patent and making part of the same.

To all whom it may concern:

Be it known that I, ALFRED S.D1C-K1Nsos, of the city, county, and State of New York,`have invented a new and useful Curtain-Fixture; and I do hereby declare 'that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings,making part of this speciiioation, in which- Figure l is a front elevation,

Figure 2, aside elevation, and

Figures 3, 4, 5, and (i, are different views of the seinicircular glass sheave. v

Like letters denote like parts in the several figures.

My invention relates to cu1tain-i.`vtures; and

It consistsin the combination of an open frame, and one or more semicircular glass sheaves fixed therein, over which the cords are to he passed for operating the curtain.

To enable those skilled in the art to make and use xny invention, I will proceed todescribe its construction and operation.

In the drawings- A represents the frame, which .may be made of sheet-metal. It is to be formed as shown in gs'..1 and 2, its base being of the necessary dimensions to receive the sheave or sheaves, which are to rest upon it, and which are to be held between the sides, which rise from the base verticallyfor some distance, and

are then made to approach eachothely-when they again rise vertically to their termination.

The upper ends of' the sides are perforated, so that the frame may be attached to the window-sash, which may be done by screwing it thereto, or by hanging it on a stud, as preferred.

B represents the semicircular sheave, which is to be made of glass, porcelain, or other such like material.

The length of the base of this sheave is such, that when it is inserted in the frame A, it projects on either side thereof, and such projecting parts have spurs b, formed ou each side, between which the sides of the frame tit snugly.

Ihe shea-ve is to have a rounded groove formedin its edge, for guiding a cord in the usual manner.

. I have shown the base of the sheave'as flat; but it may have formed upon it spurs or points, in which case the base of the frame is t0 be provided with 'co1'- responding pertbrations, into which the points of the sheave recede, thus giving it more steadiness.

The thickness of the sheave is such, that when insei-ted in the frame, which is done by springing the sides apart a little, and pushing one end of the sheave through, it is rinly held between its sides, its spurs preventing it from slipping out.

I have shown but a single sheave; but' it is apparent that two or more may be held in the same frame, it only being necessary to enlarge the capacity of the latter.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is-

A curtain-fixture, combining 4in its construction a frame, A, and'one or more semicircular glass sheaves,

'13,4 constructed and arranged, in relation to each other, as shown and described.

In testimony whereof', I have signed my name to this specification, in the presence of two subscribing witnesses.

ALFRED S. DIGKINSON.
