To all whom it may concern: I

Beit known that 1, JOHN C. SPENCER; a

"citizen of the United] States residing at Spicelanchin the-county of Henry and State Indiana, have invented certain new and {useful Improvements in A'Litomatic Shade- Roller-Controlling Means, of which the fol lowing is a specification, reference bein had tion.

I with respectto'its mountin and provide means of this character an actuating member substantially corre-,

"zula iited to engage the roller to the accompanying drawings.

This invention relates to window" shade fixtures, and. more particularly to automatic means for controlling the movement of a spring actuated shade roller;

It is an object otjthe invention to provide means of this character capable oi": causing rotation of theshade roller upon actuation of the supporting means of the roller. 1

It is another object of the invention to provide means of this character wherein the rod on WlllCll"lll16 spring "actuated shade roller isrotatablymount ed also serves as spending in length to the length of the shade roller and having shade brackets extending therefrom, the rollerbeing rotatably mount- =ed in the brackets,- and grzivity actuated brackets and to normally neveht rotation of theroll'er and to disengage and permit rotatioiiof the roller when theactuating member is moved awaytrom the shade ot tb'e roller by the operator. It i; a 'lurther object of: the invention to provide means of this character including an actuating member on which a spring actumea-ns carried byone ot'said ated shade roller is rotatably mounjtcd,the

actuatingmember and roller being. movable in unison upon adjustment o1"- thecurtain' by the curtain cordand movable independ-h ently of each "otherwhen the curtain cord is substantially locked in its adjusted posi- With these and other objects in view,the invention cous1sts in the improved construction and arrangement of parts to be herein- I a fter more window casing to the securedL; A look adapted to receivethe cord 11, the ing frictihnally engaged with the cord 11 i so that it will Y this means-the Rotatably m ori nted in the particularly described, fully -laime'd an'dillustrated in the accompanying drawings, in which Figure l is a View in elevation ot a window shade showing the automatic shade CODtTOlllIlglllQiLHS applied;

Referring to the drawings, 5 designatesa upper intermediate portion iof which a lock pulleyi bralclret 6 is form is mounted in thebracket. The pulley is adapted 'toreceive'a curtain or shade cord 7 which is connected to the window shade 8. i In order to permit the window shade to he properly balancedand maintaineil at all times in a horizontal position, there is provided a novel reinforcing bar 9 substantially rectangularin cross section, said bar being disposed in I 11 is secured at itsends to the reiniorclng bar 9 through the medium oi. suitablefastening means and cl psl2 to substantially provide a bail One end ofthe cord 7 is provided with alo'op 13 loop be- .not move accidentally.
