CURTAIN-\FIXTUREJ LPECIPICATION forming part of Letters Patent No. 362,147, dated July 15, 1884. Application fi eaiaa jas, 1884. (No modelir To [l/ZZ whom, it may concern.-

Be it known that I, WILLIAM H. LINCH, a citizen of the United States, residing at New Matamoras, in the county of Washington and State of Ohio, have invented certain new and useful Improvements in Curtain-Fixtures .and I do declare the following to bea 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 bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. The invention belongs to that class of devices by whichthe upper rod or roller of a window-curtain may be raised or'lowered to any desired position across .thewindow, the lower rod of the curtain remaining stationary meanwhile, because the upper. rod revolves, while descending, in such direction as to roll up the curtain, and unrolls the same while ascending, the object of all such devices being to admit more or less light through the upper part of the window.

The invention consists in combining,w ith a peculiarly-constructed device of the sort,

means hereinafter described, by which, when the roller is in any position, the lower part of the curtain may be rolledup, thus admitting light both above and below said roller. When the roller is at its highest point,the curtain may be entirely rolled up by the same means.

In the drawings accompanying and forming part of this specification, Figure 1 represents a front view of the invention attached to a.

window frame and curtain. Fig. 2 is aside View of the same. Fig. 3 is a side view of the swinging catch and ratchet-wheel, the bearing being broken away to show the same. Fig. 4 is a rear View of bearing, ratchet-wheel, and swinging catch, showing the pawl of the catch. Fig. 5 is a front View of the axis, showing the attachment of the different cords to the pulleys on the same.

In the accompanying drawings, A represents a window-frame of proper construction,- of which a, a are the j ambs, a the sill, and a the top rail.

B is a curtain provided with the lower rod, 6, and the upper rod or roller, 1), havingon one end the pulley b, provided with a circumferen-tial groove, and on. the other end the pulley I), provided with two similar circumferential grooves.

O (l aresimilar vertical guides or rings, fixed at equal heights in the upper part of the window-frame, at equal distances from the center of the same. The said ring must be situated above the highest point of the roller 1). one vertically over the groove in pulley b the other similarly over the inner groove of the roller 1).

D is a horizontal guide-ring, fixed in the cen tral line of the window-frame horizontally between the rings 0 O.

E E are two opposite bearings, similar to curtain-rod bearings, standing out from the window-frame at a proper distance above the ring D, at equal distances on each side of the same.

F is anaxis, each journal of which is supported by one of the bearings E. k The said axis has fixed upon it within said bearings the three pulleys f, f, and f -f on the same side of the frame as the pulley If, f 011 the same side as the pulley b", with the pulley f between them.

f is a ratchet-wheel fixed to the axis F, on

the outer side or forming the outer side of the pulley f.

H is a'curved swinging catch'pi'voted at its upper end to the inner surface at the top of the bearing E, on the same side of the frame as the ratchet-wheel. "The saidcatch curves from its pivot backward around the axis and forms the forward and upward projecting arm h in front of thesame. The outer end of the arm is bent inward, so as to lie parallel to the frame A, and is provided with the opening h, for a purpose hereinafter mentioned.

k is a projection bent inward at right angles from the rear edge of the back portion of the catch about its middle part, and which serves as a pawl tOItheratchet-WheeI. When the catch H is in its normal position, its weight ner that the revolution of the axis F in one direction will roll or unroll both equally. 'lhe cords I I descend from the pulleys, pass through the horizontal ring D, thence through the rings 0 0, one on each side. IVhenever one passes around the groove in the pulley b and the other around the inner groove in the pulley b", they then ascend, and are fastened to the shanks by which the rings 0 O are secured to the frame.

J is a cord fastened to the pulley f 2 in such manner that unrolling it rolls up the cords I I or the reverse. The cord J passes from the pulley through the opening h in the arm h, whence it hangs in front of the curtain, having on its lower end a tassel or other proper handhold.

K is a cord attached to the outer groove in the pulley of the curtain-rod in such manner that unrollingitrolls up the curtain. This cord is considerably longer than is necessary to roll up the whole curtain, and is provided on its lower end with a tassel or other proper handheld.

The operation of the device is as follows: WVhen it is desired to lower the roller 1), the cord J is pushed in toward the curtain sufficicntly to depress the arm h by the hold the said cord takes within the opening h. This releases the pawl h from the ratch et-wheel, and as the cord is not pulled down the weight of the roller,with attached curtain, is sufficient to unroll the cords I I and revolve the axis F, the cord J being permitted to slip up just sufficiently to prevent the rise of arm h. As the cords I I unroll, the roller 1) descends, and as the pulleys b and b engage the loops of said cords the roller is revolved inwardly and the curtain is rolled upon the same. As the rolling equals the descent, the rod 1) remains nearly stationary. By releasing the cord J the arm h assumes its normal position and the roller .1) becomes stationary at .any desired point.

Should it then be desired to admit light both above and below the curtain, thelatter is rolled up to any desired distance bypulling down the cord K. By pulling down the cord J the axis F is revolved in the opposite direction from the above,which reverses the action of the roller I) and cords I I, and the said roller consequentlyascends, unrolling as it goes up.

"When the curtain covers the window, it may be entirely rolled up by means of the cord K.

It is manifest that where so desired the guides O G and D, instead of being made in the ring form shown, may be pulleys, and that such change would not involve a departure from the broad principles of my invention.

In use it will be understood that the friction of the cords I on rollers b and b is sufficient to prevent said rollers unwinding by the weight of the curtain.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, 1s

1 I11 combination with a window-frame, A,

b, and upper roller, I), having on its ends the pulleys b and b the guides O C and D, fixed at proper points on said frame, the axis F, turning in thebearings E E, and provided with the pulleys f f f and the ratchet-Wheel f, the swinging catch H, provided with the pawl 72. and arm 71, having the opening h, and the cords I I, J, and K, all constructed and arranged as shown and described, for the purposes specified.

In testimony whercof I afifix my signature in presence of two witnesses.
