same. This roller and its screw extension are hung in brackets 4 and 5 depending from a plate 3 attachable to the. underside of the head-bar of a Window-casing... Pulleys 6, 7,

-a detent 8 anda lever 9 are also suspended ini connection with the aforesaid plate. The roller turns freely in the bracket 4 and the bracket 5 is in part a stationary nut for the screw-extension of said roller, the latter` and said `extension ofsame being preferably one Vpiece of wood. `l 3 Fast to an end of roller-,1, `next the screw-` eXtension thereof, is a circular ratchet-plate l() for engagement with the detent 8, and the engaged from the ratchet l0 to release said roller. Other cords `12 and 13 areea'ch conartly sectional' front The loop-arm, ofv said lever is *nora nectedatjtheirends'to the rollerl and one of `a pair of hangers 14 forthe roller 15 of the window-@shade 16, and' these hangers are preferablysleeves guided on vertical rods17 each supported in connection with brackets 1S, 19, attached to `stiles of the windowcasing. The cord 12 is trained on the pulley 6 `and'another pulley 2() in connection with the window-frame, the cord 13 is trained on the pulley 7 and another pulley 21in connection with said window-frame, and said cords wind and unwind simultaneously with relationto the roller to which they are attached. .When the detent is lifted, the cords 12 and 13 will unwind from the roller 1 simultaneously, and this roller in its revolution Will move lendwise from` right to-left ermitting gravity descent of the vother ro er 15 and shade therewith. The cord 11, if allowed to slide through, the grasp of the operator, will be kept sufliciently taut to keep 'the detent 8 Ilifted out of engagement with the ratchet 10, and thus allow free revolution of the roller 1 in the direction to permit unwinding of the shade suspending cords, but the downward movement of the shade is readily arrested at any point by slackening or pulling out of the operatingv cordtopermit a drop of said del v f Y tent intok rengagernent with sald ratchet. lReferring by numeral to the drawings, lY indicates a roller and 2 a screw-extension of l When the shade-suspending cords unwind from the roller 1, the operating-cord winds on said' roller, and when said operating cord is pulled down to unwind the same, the other cords are caused to wind and thus elevate the shade. i

The ulleys 6i and 7 are laced in front above `t e plane of the cordiroller and the operating-cord passes downin front of said roller. The tendency of the cords 12 and 13 to lift the roller in the brackets 4 and 5 is met by the tendency of the operating cord to pull said rollery down in said brackets, thus 1n a loo Having deseribediny invention, what I claim as neW, and desire to secure by Letters Patent is- 1. The combination of suspending brackets, a roller having a screw-extension and engaging the brackets one of which is a stationary nut for the screw, a pair of cords in connection With the roller, suitably arranged pulleys on Which said cords are trained, a shade having the roller thereof suspended by said cords, an operating-cord in connection With the roller irst'aforesaid to Wind and un- Wind opposite the other cords, a ratchet in connection with the cord-roller, a detent of a length suflicient to be engageable With the ratchet in any position of same, and a bellcrank lever having one arin thereof arranged under the detent, its other arni being provided With a loo engaged by the operating-cord and norma ly at such an angle that direct d0Wn-pull on said cord Will actuate said lever to trip the detent from the ratchet.

2. The combination of suspending brackets one of which constitutes a stationary nut,

r a roller and screw-extension of the saine engaging the brackets, a pair of cords in connection With the roller, suitably arranged pulleys on which the cords are trained, a shade having the roller thereof suspended by said cords, an operating cord in connection With the roller first aforesaid to Wind and unwind opposite the other cords, a ratchet in connection With the cord-roller, a detent of suitable length engageable With the ratchet, and a trip-lever forthe detent controlled by the eperatingecord with which it is engaged at such. an angle as to be actuated by direct downpull of said operating cord to trip said. detent, automatic rengageinent of the detent with the ratchet being a result of slacking the aforesaid operating-cord or of an outward pull of saine.

3. The combination of suspending brackets one of Which constitutes a stationary nuty a roller and screw-extension of saine engaging the brackets, apair of cords in connection with the roller, suitably arranged pulleys on Which the cords are trained., a shade having the roller thereof suspended by said cords, an operating-cord in connection with the roller first aforesaid to Wind and unwind opposite the other cords, and ineans controlled by the operating-cord for stopping and releasing the cord-roller.

In testimony whereof I allix iny signature in presence of two Witnesses.
