MOVABLE SHADE-ROLLER.

Specification 0! Letters Patent.

Patented May 18, 1909.

Application filed July 10, 1907. SerlalNo. 382,877.

To all whom it may concern:

which the mechanism is operated to raise or Be it known that I, (lsonon F. KsLsEi', a I lower the shade-roller.

citizen of the United States of America, and

a resident of New Brighton, Richmond borough, New York city, in the State of New York, have invented certain new and useful Improvements in Movable Shade-Rollers, of which the following is a specification.

- The ob'ect of my invention is to provide a shade-rel n' which is movable vertically in the window-sash by suitable mechanism, withoutinterfering with the unrolling of the shade, so that any desired portion of the window may be shaped, while the remainder, either above or below the shade, may be left free and uncovered. To accomplish this result, I mount the shade-roller upon suitable brackets, which, instead of being fastened to some part of the window-sash, as is usual, are adapted to slide vertically, and I provide suitable mechanism by which these brackets .are moved vertically in unison, so as to stop 1 at any desired height within the sash. It wi be understood that, if it is desired to cover the lower half of the window, only, the roller is raised so as to stay about the middle of the sash; if the upper half, the roller is raised to the top of the sash; if the middle half, the roller is set at three. quarters of the height; and so on, for any fraction of the window.

In the accompanying drawings, I have shown my invention as applied to a sash speciully constructed with a view to said application, and in these drawings: Figure 1 IS a front view, in elevation, partly broken away in section, of my invention, as applied to a specially constructed sash; Fig. 2 1s a vertical section on the line 2 2, of Fig. 1 Fig. 3 is a horizontal section on the line 3-3, of Fig. 1; and Fi (4 is a detail of a form of bracket adapted to this construction;

Referring, now, in detail to the drawings; A is the window-sash, which may be specially made with a view to receiving my movable shade-roller, and advantageously is provided, interiorly, with a chambers for the weights and operatin mechanism of the sash, and-which is more double, or lar e enough to receive, also, the operating mec anism for the shade-roller.

Bis the shade-roller.

C, C are'the brackets of a ty e to be set within or between the sash-s1 es, and are provided with grooves c, a, which slide on tracks d, d of the sash-frame.

D is the removable handle or crank, by

E, E are sprocket-wheels, suitabl mount-- ed upon the sash at convenient p aces and driven by the sprocket-chain e, which extends from the upper side of the bracket C over the entire series of wheels to the under side of the bracket. One of those wheels (prcferabl a lower one) is selected for the mitiu or riving-wheel, and is driven by a ratchet F secured thereto, from a crank D. Pivotally secured to the inner wall of chamber a, in proximity to said ratchet, is a dog or pawl G, provided with a ri ht-angled extension D, working in an arc-s ot 0' cut through the wall of said chamber, and which pawl engages the ratchet F and normally revents retro rade movement thereof and of the wheel to which said ratchet is secured. When reverse movement is desired to be ivcn to said wheel (or to the left, viewing ig. l), the operator depresses extension D and holds it with one hand, which releases the pawl from cn' agement with the ratchet F, and, with the other hand, turns the crank D to the left'as much as desired, when, u on re lease of the extension D the pawl, wil swing back into engagement with the ratchet to hold the same a ainst retrograde movement.

The shaderoll er is shown at the middle of the sash, and in that position ,fthe whole of the lower half of the window'm be covered by unrollin the shade, or any-part. of this lower half mm the bottom u may be left uncovered. By raising the rol er toward the top of the sash, by turning the crank D, it becomes possible to cover a corresponding amount of the upper half of the window,

and, by unrolling the shade as much or as little of the lower half as may be desired. It

will thus be seen that my Improved shaderoller makes it possible to cover the whole-.or

either half of the window, as desired, or, while leaving both top and bottom uncovered, to cover a strip of desired width at. any lace between the top and bottom of the win 0w.

I regard the housin of all the o crating mechanism of my eviee, including the sprocket-wheels E, E, the ratchet F, and the awl G, within the interior chamber a of the window-casing as one of the distinguishing features of my'invention; for, thereby, act-- vantageous results are obtained, as follows: Such parts are hidden from view and, thus, no unsightly protuberances or. obstructions are presented and which would tend to inter l lere with the )roper hanging of, and which would be liable to injure or tear, the lace curtains customaril used on every window r in addition to the ro ler-shade said operating parts are screened against access thereto and deposit thereon of dirt and dust; and said parts are also im JUSsilJlG of access thereto by meddlesome children, so that there is no i danger of their tampering with said niechanism and breaking the same, or getting it out of order. Another distinguishing Ieature of my invention, going to make up the ultimate perfection of the whole, resides in l the removable handle or crank I): thus, when the housekeeper adjusts the shade to l the desired position, she can remove the 1 handle, so as to obviate the 'vexation (if the handle were permanently ailixcd) of children playin therewith and running the shade up and d%wn. Besides, the removal of the 5 handle, when not in use, leaves nothing nnsightly to the view. 1

Having thus fullydescribed my invention, l what I claim as new and desire to secure by l Letters-Patent is:

1 T he combination with a window-casing, I having an interior chamber, of a shade-roller, and mecha iism for raising and lowering said roller, an cated within said chamber, a ratchet secured thereto and also disposed within said chamber, means for rotating said wheel, the wall of said chamber having an arcsslot out therethrough, and a pivoted pawl, also disposed pawl, also disposed within saidcham er and on aging said ratchet, and provided with a having an interior chamber, of a shade-roller, 40

and mechanism for raising and lowering said;

* roller, and comprising, in part, a wheel located within said chamber, a ratchet secured thereto and also disposed within said chamher, a crank for rotating said wheel, the wall of said chamber having an arc-s1 t out therethrough, and a pivoted pawl, a so disposed within said chamber and enga ing said ratchet, and provided with a rig it-angled 1 extension proierting through said slot.

3. The com )iiiation with a window-casing,

having an interior chamber, of a shade-roller,

an d mechanism for raising and lowering said roller, and comprising, in part, a wheel 10- rated within said chamber, a ratchet secured thereto and also disposed within said chamber, a removable crank for rotating said 1 wheel, the wall of said chamber having an arc-slot cut therethrough, and a ivoted rig it-angled extension pro ecting through said slot.

Signed at New York city, this day of comprising, in part, a wheel 10- July 1907.
