The Schedule referred to in these Letters Patent and making part of the name.

To all whom it meyccnccrn:

Be it known that I, Moens LonB, of Chicago, in the county-of Cook, and State of Illinois, have invented new and useful Improvements in Gurt'ainFixtures;4 and I do hereby'declare the following to be a full, clear, and exact description thereof, which will enable others' skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is an elevation of a window and sha-de showing my improved fixtures.

Figure 2 is a side view of the same, partly in section.

Similar letters of reference indicate corresponding parts in the several figures.

My invention has for 'its object toy regulate the tension of the cords by which window-shades are operated, and to prevent the cord from running oi the shade-roller.

It consists, first, in a socket affixed to the windowframe at the lower end of the cord, adapted to receive a sereni-rod, which carries, atone end, a grooved roller, over-which the shade-cord passes, and, atits opposite end, an adjusting-nut, by which the tension of the cord is regulated. I am aware that various devices have heretofore been employed for this purpose, but they are usually formed with catchesprnotches, adapted -to receive and holdl a'pawl, carrying a grooved roller,

by the tension lof the cord`l itself; or they are made without notches, the grooved roller being held against the tension' of the cord, partially by friction, and vpartially by a Wedge'. These forms are, however, imp'em..

fect in their operation, and cannot under all circum-V stances, tighten the cord properly. By the employ ment of an adjusting-screw and nut, as I propose, the

tonsionof the cord can be regulated to any degree,

with the utmost ease and accuracy.

My invention also consists in the construction of a reversible guard-bracket, for holding the cord upon the end of the shade-roller, whereby the same can be employed at either end of the roller, as circumstances may require.

nearthe lower 'end of the shade-cord, as shown, and receives a metallic bar, H, in such a manner that the latter shall be parallel to the side of the window-frame.' This bar is squared for a portion of its length, near the upper end, to correspond with the opening in the socket,'and to prevent its turning in the latter. Its extreme upper end is bifurcated, as shown, to receive the grooved roller I, around which the shade-cord F passes.

The bar H, below the squared portion, is provided With a screw-thread, to receive the adjusting-nut K, which bears against the lower 'end of the socket. By

.turning this nut, it will readily be seen that the cord F can be tightened or loosened with the greatest accuracy and facility. Y

Eis a bracket, forming one of the bearings for the shade-roller, as. previously mentioned. It is provided upon its outer end with a plate, L, at right angles to `the main portion, and extending an equal distance upon each side of the same. This plate projects over the front-portion of the grooved pulley G, andserves to prevent-the cord F from running off said pu11ey.

The object of extending the plate L upon both sides ofthe main portion of the bracket', is to adapt the lat# ter for use ateither end of the roller D, according to the side ofthe window-frame upon which it is desired to locate the socket and adjusting-screw. Thus a reversible bracket is obtained, capable of use in alll situations.

Myv invention isl productive of simplicity and economy in the construction of curtain-fixtures, and renders the operation of windoyv-shades'much more perfect than it has been hitherto.

'Having thus described my invention,

What I claim as new, and desire to secure by Let-V roller D, constructed and arranged as shown and de scribed.

The above specification signed by me, this 31st day of August, 1869.
