WINDOW SHADE.

Application file-:1 June 28,

The invention has for an object to efi'ect improvements in shade construction, to the end that a desirable arrangement and apparatus permitting thesatisfactoryuse of roller shades adjustable bodily without rolling or unrolling, as well as permitting the winding and unwinding of the roller, may be accomplished. c

I am aware that many constructions for the vertical bodily adjustment of shade rollers have been evolved, and I am also faniiliar with the fact that devices in which a shade may be unwoundin two directions from the same roller have been developed. lrly experience as aspecialist in the manu facture and installation of roller shades for a long period of years has shown, however, that all of the devices and patents with which I am familiar are deficient in one or more im-v portant respects, and not satisfactory for general use. It istherefore an object ofthis invention to presenta construction, and combination of elements makingfor practicability in manufacture ofsuch devices, as well as having a strong appeal tothe public be-' cause of the simplicity of the installation and manipulation thereof, durability and freedom from liability of impairment or derangement. I

There is illustrated in Figures 1 to 3 inclusive, a window frame including the usual lintel 15 and sill 16, with the usual jamb facing 17 extending therebetween at the sides. A single pulley-18 is secured upon the under side of the lintel at the extreme left hand side of thewindow opening, while a double pulley 19 is secured in a similar situation at the right handside. Suitable. cordslorv cables20 and 21 drop from the left hand side of the pulley 18, and one wheel of the pulley 19 respectively, the other wheel of the last named pulley having the first mentioned cable extended thereover and downwardly beside the outer side of the cable 21,,the two being secured to a.

common adjusting cord 22 which may be engaged with a releasable clamp or other equiv:

alentdevice 23 on thefacing of the frame at one side. The. extremities of the, cab es 20 21 are attached to an adjuster bar 24 attached to the upper portion of a window shade 25, to the lower part of which a roller 26 is suitably secured so that this shade portion may be wound thereon. A continuation of the shade, or a separate lower shade pol; tion 27 of equal area extends downwardly from the roller, the shade portions being so attached to the roller that both may be wound upon the roller. simultaneously by rotation of the roller. 1

The roller is extendedsuitably at each, side of'the shade and provided with a winding drum portion 28, having suitable flanges, the

inner flanges being located suitably to accoms.

modate the shade freely. Single pulleys 29 are mounted at each end of the adjuster bar 24, vertically over the drums 28, and a denble pulley is mounted upon the bar 24 in line with the pulleys 29. Respective cables 31 are connected to the drum, extended upwardly therefrom at the outer sides of the pulleys 29,.inwardly over these pulleys, and then horizontally inward and over respective wheels of the pulley 30, then downwardly,

and connected to a single operating cord 32,

7 tion of the window only by drawing upon the cord 32 as desired, and the shade may in this manner be entirely withdrawn to the upper part of the window opening. Should it be desired to admit light at the upper part of the window only, the cord 32 drawn until the opening at the top and bottom equal about that which it is desired to leave at the top, the cord 32 is then fastened at 33, and the cord 22 loosened and paid out untilthe lower shade portion 27 reaches the sill. In the first described operation, drawing upon the cord 32 will cause unwinding of the cables 31 from thedrum, and consequent winding of both shade portions on the drum, and the roller will reach the top of the window as both shade parts become completely Wound thereon. If both the cord 22 and cord 32 are moved simultaneously the same distances, the shade may be readily shifted without change on the roller. At any position of the adjuster bar 24:, the shade portions may similarly be completely wound thereon, the roller reaching the adjusterbar coincidently with the winding of the shade element.

In the second operation above mentioned.

for admission of light, when the cord22 is paid out, lowering of the adjuster bar admits the feeding of the cord 32 and cables 31 upwardly, and outwardly over the double pulley 30, and as the weight of the roller and wound shade portion thereby become sustained more upon the upper shade portion than upon the cables 31, unwinding of the shade portion will ensue with consequent winding oi. the cable portions 31 as they are fed through the pulleys. By drawing upon the cords 22 at any time, upward. movement of the adjuster bar 24 will cause a pull upon the cords 32 by reason of its attachment at 33 and consequent pull on the cables 31 will cause rotation of the drum 26 to wind up the side of the window as desiredv cable portion at the same time that the drum is moved upwardly, as will be readily understood.

In Figure 4 the adjuster bar 24 is supported by a single pulley cable 34, extended upwardly from the bar over a single pulley 35 centrally of the lintel, and then downwardly to a suitably located fastening 36, which may be located centrally of or at one A single pulley 37 is mounted at the left hand side of the window casing and a double pulley 33 at the right hand side. The shade and roller construction may be the same as before described, and the cables 39 extended from the respective drum portions, the one 39 from the left being extened upwardly and over the pulley 37, then tot-he right over the pulley 38 downwardly, while the other cable extends upwardly at the inner side of the pulley 38, then outwardly thereover and downwardly beside the first cable 39, the two being connected at a suitable point to an adjusting cord 41 for which a fastening d2 of a suitable nature may be provided at a convenient point. The operation of this form of the device is similar to that previously described, the cable 34 being operated for the tunctionof the cord 22 be fore mentioned, while the cord 41 is operated for the function of cord 32, previously described.

In Figures 5 to 7 inclusive, refinements of the device as now (lISClOSBd are presented,

adapted to improve or assure efiicientfunctioning, and to improve its appearance. Here, the drum portion upon the roller is formed by turning a groove 43' of substantial width and depth to accommodate the cords such as 31, and 39, previously described, and a rabbet 44 is formed on the roller at each side of this groove, into which a cylindrical case 47, open at one side, is adapted to be snapped, an opening 46 being formed therein, at a point through which the cord wound on the roller may be extended, this case being adapted to set very loosely in the rabbet so as to rotate thereon when the cable is wound or unwound, the side of the o enin 416 being well rounded to revent P c: P

abrasion of the cable.

In Figure 8 there is illustrated a construction. in which a spring roller 26 is utilized, with a means for ad usting the roller VQI' tically, and also taking advantage of the extension of the shade in opposite directions from the roller. In this instance, stationary guide wires 51 are tautly secured between the sill and the lintel of the window at respective sides of the window opening, and vertically'slidable upon these wires there is an adjuster bar 52, upon which, by means of suitable brackets such, as are ordinarily used, there is a mounted spring roller shade. This roller may comprise any familiar form of spring-actuated roller in which the spring 3 ill!) "In I cured adjustably ti l is connected with a trunnion of angular form engaged in a corresponding opening' in thebracket 53, whereby the trui'inion is held against rotation. The usual dog construction found in such rollersmay also be employed to theend that while the shade may be withdrawn from the roller and rewound thereon by action of the spring when the shadeis quickly released at times, it may be held in extended position when allowed to slowly rewind until held by theautomatic dog device, as is familiar in such shades. This kind of roller-being quite generally familiar and largely used in the art is not illustrated, as the details of the spring and dog control comprise"nonovelpart of this invention. The shade parts 25 and 27 are at tended above and below the roller respectively as previously described. A shade rod 56 is engaged in the upper cdge'of the portion 25, and projected laterally there from, receiving the wire 51 'slidably through its encs." Single pulleys '57 are located respectively at the middle of the lintcl and at the extreme'left side of the window opening, while a. double pulley 58 located at the ri ut hand side of thewindow' opening in cornspondingposition; The adjuster bar 52 i. supported by cables '59 which EIXQ'GXfGZlClGtl upwardlyfrom respective ends thereof, the left being carried over the pulley 57, and then horizontally to the right, both being then extended over one roller of the pulley 58 and downwardly to a cord 60 which may be seby a fastening 61. A cable 62 is connected centrally to the rod 56, being extended upwardly over the pulley 57 to the right, then over the remaining wheel of the pulley 5S and downwardly, and either connected directly to the cord 60, as shown, or separately fastened if desirec. In the op eration of this form of the device, in case it is desired to adjust the shade with the upper or lower part extended without change, the cord 60 is manipulated to raise or lower the bar 52, and the cable 62 being connected thereto, the shade will be held in the same extended position without rotating the roller 54 during such adjustment.

It may be found preferable to connect the cord 60 to an idler or floating pulley 63 sus pended in a loop formed by a continuation of the cable 62 from its junction with the cables 59. In case it is desired to shorten the shade, the lower adjusting cord 64 attached to the lower shade portion is grasped and manipulated, and extension of the shade may be accomplished in the same manner. In extending the shade, in case the pulley 63 is incorporated, the cable 62 will be fed upwardly and cables 59 thereby caused to lower the adjuster bar 52, and if this bar thus becomes lowered too far, it may be raised again by subsequent adjustment of cords 60.

In Figure 9 a modified arrangement utilizing the spring roller is shown, the guidewires, adjuster bar and mounting of the shade on the adjuster bar and engaged with the guide wires being the same as last described, except that a bottom shade rod 56 is in the lower edge of the shade portion 27 and in en gagement with the wires 51. A double pulley 66 is mounted centrally of the lintel, another double pulley 67 located at the side of the window 0 Jening, while a siniilar double pulley 68 is mounted a short distance still further outward of the one last mentioned, all three on a level. A single cable 69 is extended from the middle of the adjuster bar, upwardly and outwardly over all of the pulleys, and then downwardly to an adjusting cord 70 whichis provided with a fastener 71 at a convenient point. F roni the middle of the top shade rod there is extended is also passed similarly over all of the pulleys and then downwardly, being attached to the cord 70. Pulling upon the cord will operate both cables to raise the adjuster bar and upper shade together, thus leaving the shades in the same pos' ion relatively to the roller while the entire shade is adjusted vertically; Between the pulleys 67 and 68 the cable 72 formed with loop in which'there is a floating pulley 74: having an adjuster cord 75 secured thereto, a separate fastening 76 being provided for this cord. The cord 70 being secured at 71, the shade may be wound or unwound by manipulation of the cord 75 in the familiar Way, a steady pull. serving to draw the shade element from the roller, while a slight jerk and quick release will permit the roller to rewind the cable. It is of course understood that the spring roller in both this form and that described previously should have the proper tension for the functions involved.

In Figure 10 there is shown a roller bracket mounting 77 which is adapted to serve in guiding the adjuster barsecurely upon the vertical guide wire. In this mounting the adjuster bar has the guide wire extended slidably therethrough, and upon the lower side of the adjuster bar there are mounted brackets 77, each of which has a vertical intermediate oortion and horizontal inwardly and outwardly extending arms 78 and 79 at top and bottom respectively. The lower arm is suitably apertured to receive the guide wire slidably, and the upper arm is adapted to receive the usual fastenings therethrough. he vertical intermediate portion of one is slotted to receive snugly the flat roller trunnion as commonly formed, while the other bracket has its corresponding part apertured to receive the cylindrical trunnion revolubly.

In Figure 15 there is shown a further modification of the mounting for the roller, which is adapted to eliminate the adjuster bar. In this instance, a bracket alone is provided. The bracket includes a vertical intermediate second cable 72, which portion 85, suitably slotted or apertured to receive the usual trunnion 86 of a spring roller, which is inserted through this portion 85, and the trunnion 86 is preferably apertured to receive a retaining pin 87 or other retaining means provided thereon. The braclcet is provided at its upper and lower parts with outwardly extended arms 88 and 59 respectively, the former being the longer, and having attached to its outer part such cables as might have been attached to the ends of the adjuster bar in the previously described forms of the invention. The two guide wires therethrough slidably.

arms are suitably apertured to receive the The manipulation of the device utilizing this bracket is the same as the corresponding arrangements where the adjuster bar is employed, as, for instance, illustrated in Fig ure 8.

It will be seen that a very simple apparatus is provided for the mounting of roller shades ina novel way, adapted to be pro duced at low cost and without involving radical departures from ordinary shop practices. The device may be variously modified within the scope of the invention and various combinations of the features in .the several modifications adapted for transposition may also be made, as will be readily understood.

It is an advantage in several of the arrangements shown that the shades can be better manipulated without grasping the lower edge of the lower section and thereby the shades will be largely protected from becoming soiled in manipulation when my invention is employed. The device is quite durable and adapted to work smoothly with a minimum liability to derangement.
