5' Claims;

This invention relates to an improved demountable window shade assembly and has. for one of its: principal objects the provision of a novel means for positioning a pair of. cooperat- 5 ing window shades, whereby the same withr their common support. may be conveniently removed from normal operating position particularly for some. temporarypurposeg, as; for example. the washing. of windows; or: thealike;

Qne. of the important. objects of. the: invention is the provision of. a support for. windovgshades or the like which shall be detachablypositioned in a simple-yet efiicientmanner for ready removal and. shifting to another portion, of the. window frame when necessary or desired, and. for. as ready 2, replacement. when; the operation for which said. removal became. necessary has been completed.

The invention is; particularly designed for use with. window shades, such asare commonly'eme ployed in school or similar. buildings, wherein a pair ofshades mounted OIlz rollers is, positioned adj acentthe middle portion of. a. window, whereby one shade can beldrawnupwardlyflandthe other downwardly away from. each, other to; cover any or all desired portions, of the windows.

Other and further important objects, of the invention will. be. apparent. from. the disclosures in. the accompanying drawing; and following specification. I

The invention, ihapreferred form,isil1ustrated in the. drawing, and hereinafter more. fully' described; V

In the. d'mwi'ng;v

Figure 1.. is a vertical. elevation. or a window frame, showing. the improved demountable. win dow shade assembly oil this.v invention applied thereto.

Figure 2' is an enlarged detail view of oneenid of, the window shade. assembly, of l the, invention, showing. parts of' the shades o'nrollers, aportion of the light. strip, and. one. ofithe holders.

V g I Figure 5 is a. front view. of: the holder of. Figure 4, but illustrating. the same. as. positioned ona diiferentn portion. of. a window. frame,' a s. the out..- side. facing. 7

Figure 6.is,al view showingtherupper partofa window frame with the shade assembly of. this invention-in raised position thereon so as to be out of the way for some operation on the windows, as, for example, washing the same.

As shown in the drawing: The reference numeral l indicates generally 60 a window frame which has a pair of roller shades l-2 and Mt applied. thereto, the same being positinned on what-is known as a light stripl6 ,,this light strip beingi. preferably of metal andextending across the medial portion of the window, and having the shades I2 and M, withtheir rollers, positioned thereon as shown inmore: detail in Figure 2 and in: such relationship that light will not pass. directlythrough the space-between the rollers. I

Asbest shown inFigure 3, the light strippreferablyhas its. upper and. lower edges beaded; as at l8, and either integral with: or attached to eachend of the light strip IB- is a forwardly ex:- tending. portion 20 having bifurcated brackets 22-and 24: respectively, which brackets arep-rovided with; the usual openings and slotsfor the reception-:ofthe pins 26: and 28 which form part of the shade rollers; Obviously, the brackets on. the other end of the light strip: l6" have. corresponding: openings and bayonet slots. for the reception. of the. correspondingly: shaped roller pins at that end.

A holder such as that shown in. Figure- 4: is fixedtateach side. of the.- Window-frame: l0, each holder. prefer bly comprising a strip- 34 which has itsupper end, bent horizontally as shownat 35 andwith. itselower end bent into a channel. or hook shape: as illustrated at 38,-. Integral with this ship 34 is. a supporting plate element 30 which,in certaininstallations-such asthat shown in: Figure. 4-, is for attachment to the windowframe by means: of screws or the like 32 passing through suitable openingsrinv the plate. 30

The strip 34 is itself provided with openings through. which fastening screws Ml may pass; as best shownin-Figure. thereby adapting the same tobe: mountedronthe forward. or front face of awindow-frame=instead of on=the inner face or side thereof asrexemplified. in Figure 4-. Latching. pins- 42 provided. with. flattenedlupper endsJlL, which act as handles, are providedlfor insertioninto suitable and correspondingly shaped openingsinthe horizontalportions 36,0f theholdersl' As best. shown. in Figure. 3:, when these. latching pins arein position, the light strip |.B.=with.its appurtenances.- is. held in. position in the holders, The light strip may be made. in; two or: more. telescoping sections so that it. may be adjusted tQ-var-ying. widths of. windows. 7

As; will. be obvious. from: an. inspection of. Fig.- ures 2 to.-5 inclusive, the light strip.- l6, withits end fixtures 20-42-24 affixed thereto, can be readily, inserted intothe ho1ders-3l).-34- by first removing the: latching. pins 42 from thelopenings.in,the,elements-36 and which can be readilygrasped by, theiruppenextensionsM}. When these pins are removed, the light strip with its appurtenances can be inserted into the channel portions 38, and the upper edge thereof then pushed inwardly under the projection 36 into It is preferable that the shades I2 and [4 with their supporting rollers shall have beenpreliminarily inserted in the supporting brackets 22 and. 1

24 at either end of the light strip, but the rollers and shades can be inserted after the'light strip is in position in the holders 34. I2 is operated by means of the usual cord 46, and the upper shade is preferably operated bya cord 48 which has its ends fastened to the edge of the shade as shown in Figure 1 and which passes over suitable pulleys or the-like 50 mounted on the frame with a loop 5| extending outwardly beyond the pulleys, to which loop is attached one end of an operating cord 52. The lowermost end of this cord 52 can be fastened toa suitable hook or projection 56 mounted on the frame [9. A somewhat similar provision is made at 58 on the window sill for securing of the lower end of the cord 46.

Whenever it is desired to obtain free access to the windows as, for example, when the same are to be washed-or the like, the shades are rolled onto the rollers, and the cord 46 is then wound around the rolled-up shades and the light strip as best shown in Figure 6, and temporarily secured, after which the shade assembly is removed from its supporting holdersby first pulling the securing pins 42-44 and then simply tilting'the entire assembly, including the light strip, forwardly, and thence upwardly out of the channel 38. After this, the cord 52 is operated to draw the entire device upwardly to the top of the frame as-best shown in Figure 6, and held by tying to the projection 56, whereupon ready access can be had to the entire surface of the windows, sashes, etc., and after the washing or other operation has been completed, the device may be as conveniently replaced in the proper operating position.

It Will be seen that herein is provided a window shade assembly which, while retaining all the advantages of the double shade structure, also eliminates many of the difficulties and disadvantages heretofore considered necessarily associated therewith.

In the matter of washing the windows particularly, it has been found that, in installations of this type, the shades cannot be very readily removed as individual units, and the tendency has been for window washers to attempt to clean the windows without removing the shades, resulting in spattering of dirty water or the like over' the same, after which they soon becomespotty and discolored, and, therefore, unsightly. Furthermore, the water on the fabric tends to shorten the life of the shades. By the use of the present invention, all necessity of removing the shades individually is eliminated, as the entire structure can be conveniently displaced and as readily replaced. The device is also particularly --applicable in the, event of the necessity of repairs to windows such as the replacing of glass, or any other changes or repairs, such as those which would involve the installing or replacement of sash locks and sash cords or the like. The invention is also useful and eliminates considerable extra work when painting is being done. 1

The lower shade I am aware that many changes may be made and numerous details of construction varied throughout a wide range without departing from the principles of this invention, and I, therefore,

. .do not purpose limiting the patent granted hereon otherwise than as necessitated by the prior art.
