Specircation forming part of Letters `1j". atent No.f 203,418, dated M ay '7, 1878 application filed l y December 2o, 1877.

eration in connection with a pendulum-lever pivoted to the bracket supporting the end of the roller, which lever is adapted to be swung by the raising-cord to cause its upper end to engage or discngage one of the studs on the aforesaid head-disk of the drum.

The object of the present invention is to .provide a reversible arrangement by which the operating devices can be placed at either end of the curtain-roller; and to this end my invention consists in a bracket constructed with a journal-bearing for the curtain-roller, a slotted base-plate, and openings at the upper and lower parts of said bracket, near the baseplate thereof, in combination with a pendulum-lever having a lip at its upper end and a stop projecting from its side, for engaging with a series of studs projecting from a disk attached to the curtain-roller, as will be fully hereinafter described.

In the drawings, Figure l is a front view of my improved curtain-fixture attached to a Window-casing. Fig. 2 is an end elevation, showing the bracket, pendulum-pawl, and studded disk; Fig. 3, a view of the roller, drum, and studded disk separated; Fig. 4, a view of the inner sides of the bracket and pendulum-pawl Fig. 5, a perspective view of a reversible bracket.

The roller A has formed thereon a tenon, a, having acentral socket, al; and B is a drum, which ts upon the tenon a, and has a flange, b,

which abuts against the shoulder a2 of the roller, the drum extending beyond the end of the tenon, and having in its outer edge two notchesmJ u, ashort distance apart. Gis adisk of the same diameter as the flange b, and havingl projecting centrally from one of its sides a spindle, o, and from its other side a hub, c1,

upon. which is turneda journal, c2. N eartheV 'peripheryfand on the same side of this disk with the hub, and projecting in thesame direc-1 in the opposite direction from its other end,

while in the same direction with the bent arm projects .a stop, F. Gr indicates a bracket with a slotted base-plate, g, by which it is attached to the window-frame. In the outer end of this bracket is a bearing, g1, for the journal c2 of disk C, and near the base of said bracket, in obliquely-opposite directions from the bearing gl, are holes g2 g3, into the upper of which, as shown in the drawing, extends the lipped stud e3 of the pawl-lever, the lip e3 preventing the pawl-lever from falling therefrom.

lIn placing the parts together, as is usual, the drumB is placed upon the tenon a, upon which it should fit snugly, being prevented from turning by two points, p, which are driven into the shoulder of the roller.V The spindle c is then driven into the central socket of the tenon, which extends into the body of the roller, and the disk is brought snugly against the edge of the drum. Thelipped stud e3 of the pendulum pawl-lever is then inserted into the upper hole g2 of the bracket, and when the pawl-lever hangs freely and the journal c2 is inserted in the bearing g1 of the bracket, the stop F is directly in the path of the studs projecting from disk C, and will prevent the rotation of the disk C by the action of the weight of the curtain W. A knot is made in one end of the cord 7c, and, the other end of said cord being passed through the notches in the hub, the knot is drawn close up to the hub, as shown in the drawing, and the free end of the cord hangs downward through the slot in arm e.

The fixtures at the opposite end of the roller from those just described consist of a simple roller-cap,I,'having a central journal, t', which extends in the lower part of a reversible bearing, h, in a reversible bracket, G. The bracketat the other end' is also reversible-that is, both brackets may be changed to opposite sides of the windowl the stud e is inserted in hole g3 of bracket G.

The operation of the invention is as follows While .the curtain is up the cord is unwound from the drum, and hangs freely downward through the slot of arm e, the pawl-lever hanging directly downward. The stop F pre- Vents the rotation of the disk, and therefore the curtain cannot descend. Now, when it is desired to lower the curtain, the lower end of the oord is drawn downward, throwing` outward the arm e and bringing the stop F toward the hub c1 and out ofthe path of the studs D, thus permitting the rotation of the disk and the descent of the curtain. On releasing the end the lever-pawl will fall back to its natural position, and the curtain may be stopped at any point desired, and when it has been lowered its full length the cord is so wound upon the drum that when pulled downward the roller will be caused to rotate and wind it again entirely, or much as desired. WhatI claim, and desire secure by Letters Patent, is-

The bracket G, constructed with bearing gl, a slotted base-plate, g, and openings (1293 at the upper and lower parts of said bracket, near the base thereof, in combination with the pendulum-lever E, having a lip, e3, at its upper end and a stop, F, and the disk C, having laterally-projecting studs D, substantially as and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of the subscribing witnesses.
