WINDOW-SHADE FIXTURE.

SPECIFICATION forming part of Letters Patent No. 617,190, dated January 3, 1899.

Application filed March 2, 1898. Serial No. 672,245. (No model.)

To @ZZ whom, t mary concern.'

Be it known that l, JOHN SCARLETT, a citi- Zen of the United States, residing in Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in VVindow-Shade Fixtures; and I do hereby declare the following to be 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 accompanyin g drawings, and to letters of reference marked thereon,which form a part of this specification.

This invention relates to improvements in that class of window-shade fixtures which are adapted to suspend a window-shade in front of a window so as to admit light at the top of the window or at any other desired part of it, and is an improvement on the device covered by United States Letters Patent No. 475,228, of May 17, 1892.

The object of the invention is to provide a simple, strong, and durable fixture capable of being quickly and easily arranged on any window-frame, and which iixture is self-ad I justable to shades of different widths.

The invention consists in the improved window-shade fixture and in the combination and arrangement of the various parts thereof, substantially as will be hereinafter more fully described, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure l is a front elevation of a Window and window-shade provided with my improved iixture; Fig. 2, an enlarged detail view of the right-hand portion of said iixture; Fig. 3, an end elevation of Fig. 2; and Fig. 4, an enlarged detail view of the left-hand portion of my improved fixture, embodying a slight modification from what is shown in Fig. 1.

In said drawings, d represents a windowshade arranged on the ordinary spring-roller h, suspended in brackets c and d, which latter depend from and are made integral with the horizontallynarranged rods e and f, respectively. Each of said rods is provided on its free end with a collar or enlargement/L' and is slidingly and self-adjustably arranged within the tube g, and for that purpose is surrounded by a spiral spring 7L, bearing with one end against the said collar or enlargement t' and with its other end againsta plug or head in the end of the tube g, as clearly shown in Fig. l of the drawings.

To the upper portion of the bracket cis adjustably secured by means of a bolt m an auxiliary bracket o, furnishing the bearings for a sheave or pulley q. To the upper portion of the bracket d is likewise adj ustably secured by means of the bolt n an auxiliary bracket p, carrying the sheave or pulley r.

The auxiliary bracket p is suspended by a cord s, which is secured at one end to an ear on said bracket and which extends upward over a grooved pulley a: on the respective upper corner of the window-frame and then extends downward and is secured to a handles" of any suitable construction. Said handle is provided at its top with an eye or ring z2, substantially at right angles to the center line of the handle, and is slidingly arranged on a rod z3, parallel with the window-frame, and secured thereto with its upper and lower portions in any desired manner.

The auxiliary bracket o is suspended by a cord s, the free upper end of which is secured to a hook or 'eye in the respective corner of the window-frame a. Said cord passes beneath the sheave or pulley q over the pulley r in the bracket p to a fastening-clamp y, arranged at any convenient place on the window-frame.

It must be remarked that the cord s passes also over an intermediate pulley fu, arranged in a bracket w upwardly extending from the central portion of the tube g.

Whenever it is desired to raise or lower the window-shade, together with its fixture, the handle c" is simply moved against the rod a3 until the ring (which in normal position is at an angle to said rod and accordingly binds against the latter) is substantially at right angles to said rod and thus free to slide on the same. The fixture is then raised or lowered to thedesired position, and after the handle is released it is firmly suspended in said position, as will be manifest.

When the shade is to be inserted into the brackets c d; the latter are moved outward IOO against the action of the spiral springs h h, and after the trunnions of the shade-roller have been placed into their respective brackets the latter are' released and will irmly hold the said shade-roller and shade. By this arrangement the window-shade fixture is rendered self-adjustable andis capable of receiving window-shades of different widths. However, it must be remarked that it is necessary for the proper and easy working of the raising and lowering mechanism for said shade-tixture that the upwardly and downwardly projecting end portions of the cord s are at all stages parallel to each other, and for that purpose the auxiliary brackets o and p are made adjustable on the brackets c and cle-that is to say, each of said brackets can be moved in an arc (when, for instance, a narrower or wider shade has been insert-ed into the said brackets c and CZ) until the parallel position of the ends of the cord s is obtained.

Of course the auxiliary brackets can also be made integral with their respective downwardly-extending brackets-as, for instance, shown in Fig. 4; but the arrangement heretofore described is far more practical.

I do not intend to limit myself to the precise construction illustrated in the drawings and described in the specification, as various alterations could be made without changing the scope of my invention; but

That I claim as new, and desire to secure by Letters Patent, is-

l. In a window-shade lixture, the combination with the shade-roller, of a bracket at each end of the roller and each provided with an inwardly extending horizontally arranged rod, a tube inclosing the inner ends of said rods, spiral springs in said tube for controlling said rods, a guiding-cord extending over pulleys carried by said brackets and over an intermediate pulley carried by the tube, said cord being secured to the opposite sides of a window-frame at points above and below the brackets, a vertical rod on one side of the window-frame, a ring slidingly arranged on said rod, a handle supporting said ring, and a lifting-cord secured with one end to said handle and with its other end to one of said brackets and passing over an intermediate pulley arranged on the window-frame and above the last-mentioned bracket, substantially as and for the purposes described.

2. In a window-shade fixture, the combination with the shade-roller, of a bracket at each end of the roller, and each provided with an inwardly extending horizontally arranged rod, a tube inclosing the inner ends of said rods, spiral springs in said tube for controlling said rods, an auxiliary bracket adjustably secured to each of said brackets, a guiding-cord extending over pulleys supported in said auxiliary brackets and over an intermediate pulley carried by the central tube, the said cord being secured to the opposite sides of a window-frame at points above and below the auxiliary brackets, a vertical rod on one side of the window-frame, a ring slidingly arranged on said vertical rod, a handle carrying said ring, and alifting-cord secured with one end to said handle and with its other end to one of said auxiliary brackets and passing over an intermediate pulley arranged on the window-frame and above the last-'mentioned auxiliary bracket, substantially as and for the purposes described.

3. In a window-shade fixture, the combination with the shade-roller, of a bracket at each end of the roller and each provided with an inwardly extending horizontally arranged rod, a tube inclosing the inner ends of said rods, spiral springs in said tube for controlling said rods, an auxiliary bracket adjustably secured to each of said brackets, a gud- Witnesses z.
