Patented Ang.` 9, 1932 THOMAS E. MCN'ULTY, 0F ALAMEDA, CALIFORNIA CURTAIN GUIDE Application led September 16, 1929. Serial No. 392,998.

The invention Vforming the subject matter of this application relates to guiding devices for shades or curtains.

The primary object of the invention is the provision of a vdevice for suspending a window shade in such a manner as to prevent the flapping of the ends and the edges thereof, at

the same time allowing a variety vof adjustments of the window shade positions, means l0 being provided to positively guide the window shade or curtain in i-tsmovement while the same is brought from one position into another desired position.

Another object of the invention is the provision of a guiding device for a window shade or curtain, which is suspend,- ed in operative relation to a window, said guiding device positively maintaining the window shade in true alignment at all 0 times and preventing the binding of the window shade on its guides.

Another object of the invention is the pr0-` vision of parallel guides for a window shade, which shade or curtain is suspended on a pull cord in such manner as to hold the free end o-f the window shade stationary and allow the movement of the spring roller of said shade relatively to `the free end thereof; 3,) means being provided on the opposite edges of said window shade or curtain vfor positively guiding the window shade in its movement on the guides; furthermore, the window shade is provided with a positioning element adjacent the spring roller thereof for the purpose of arresting the rolling and unrolling of the shade. The entire window shade may be raised and lowered as a unit, and the free end of the shade may be! made station ary whereby the window shade may be rolled and unrolled to any desired extent. V

Other objects and advantages are to provide a guiding device for shades or curtains, that will be superior in point of simplicity,y

inexpensiveness of construction, positiveness of operatiom'and facility and convenience in.

use and general efficiency.

In this specification and the annexed drawing, the inventionis illustrated in the form` considered' to be the best, but it is to be underv It will be noted that the spring roller is not stood that the invention is not limitedto such form, because it may be embodied in other forms; and it is also to be understood that in and by the claims following the description,

itis desired to cover the invention in whatv soever form it may be embodied.

The invention is clearly illustrated in the accompanying drawing in which VFig. 1 is a front view of my window shade y guiding device, supporting a window shade on a window;

VIn its general organization my device comprises a window shade 6, suspended on a pull cord'7, and slidably guided on parallel guides 8, which guides 8 are mounted on the window 9. c I

The window shade 6 is of the roller shade l85 type, and one endthereof is wound around a spring roller 11, while the other end thereof is provided with a strip 12 tothe center of which is atached an end ofthe pull cord 7. 4

mounted iXedly on the window, but it is movable relative thereto. In order to arrest the movement of the roller 11 relatively to the strip 12, I provide apositioning barl'so disposed as'to bear against the under side of the window shade. On each end of the bar 13 is secured a socket 14 having a central openv ing 16 therein, in which opening is rotatably supported a retainer loop '17 the latteris formed of a bent wire, the ends of the wire are 16" Y rebent outwardly so as to engage theinner struction; the ends ofitsshaft are lfixedly held relatively to the positioning bar 13 by means of brackets 19, which brackets are fixedly attached t0 the bar ,13. rEhe window shade or curtain 6 is so wound on the roller 11 that its under side bears against the bar 13 as` clearly shown in Fig. 4,therefore when the positioning bar 13`is freelyjsuspended, then the weight of the spring roller 11 holds the roller V11 below the bar 13, therebyhold- I ing the shade 6 in frictional engagement with 6G justed to any released shade 6 to any desired extent.

said bar 13, thus preventing the unrolling of the shade. In yorder to unroll the shade, it is necessary to turn the handle k18 and the bar 13 therewith, outwardly, away from the window casing, so that the shade 6 is freed from the frictional engagement with the bar 13; and then pull the bar 13 downwardly, away from the strip 12, thus unrolling the The releasing of the handle 18 and the return of the roller 11 to its original position by its own weight, automatically arrests any further unrolling or rolling ofthe shade 6. The raising of the shade is effected similarly to the lowering, by Vmoving the rolled end of the shade toward the strip 12,-the spring roller acting in the usual manner.

The guides 7 are preferably made of suit-- able wire stretched between brackets 21 and Y one guide 7 on each side of the shadel 6, the

guides being parallel with each other.- .'Ihe bar 13 is adjustable on the guideswhen the shade is raised or lowered, and is maintained in true relative position by its swivel,`retain ing loops 17 which surround the respective guides 7. The shade is raised or Vlowered in its entirety without binding -or without accidental rolling or unrolling -the shade. This is made possible by the arresting of the spring roller action invaiiy desired position. Thus by lowering or raising thestrip 12 by means ofthe cord 7, the ventire shadeis adposition on the window, Vas va unit. Y

ther-.strip 12, I secure. aclevis 26 on each end In order to further obviate binding of vthe `tively to the guides 7 and to the window.

The proper alignment of the shade with the guides, obviates binding on the guides, and greatly facilitates the lowering or raising of 'the entire window shade in both rolled and unrolled position. j

As heretofore stated, the entire shade is suspended on the cord 7, which in turn 'is guided on a pulley 27. 'The pulley 27 is rotatably supported in a'bi'aclret 28 fixed on the window casing. The pulley 27 is of the locking type, it is provided with the usual threads at the opposite ends thereof, so that when Vthe cord 7 is pulled ovei said threads it is locked' therein, alsoloclng the pulley against rotation, whereby the entire shade is suspended in its adjusted position. When the cord 7 is thus fixed, it prei/'ents the downward movement of the strip 12, therefore the rolling and unrolling of the shade to any desired degree is effected by the moving of the spring roller 11 toward or away from the strip 12 in the manner heretofore set forth.

It will be recognized that the aforedescribed guides and supports for a rolling shade positively maintain the shade in any 'adjusted position, and allow a great variety of adjustments of the shade position; `The device is simple and rugged in construction and positive in operation; it does not require any careful setting up or adjustment, therefore it readily lends itself to effective application and use. v
