To all 107mm it may concord.'

Be it known that I, ZEPHANIAH TALBOT, a citizen of `the United States, residing at Ilolliston, county of Middlesex, State of llIassachuset-ts, have invented an Improvement in Vindow-Screens, of which the following description, inconnection with the accompanying drawfing, is a spectication, like'letters .on the drawings representing like parts. v

This invention relates to screens for windows and the like.

screen embodying yall of the features of the invention, collectively considered, possesses numerous desirable qualifications. For example, the screen is readlly adjustable to close an opening of the lower sash of a Vwindow withoutl at the same time obstructing the entrance of 1i ht through the upper sash; and it may be further adjusted so as to close an opening of thenpper sash.

Prior to this invention adjustable screens have been employed to coperate with the lower sash of a window; but no such screen has been'arranged for further adjustment for the 'additional purpose of closing an opening of the upper sash. Also screens have been used heretofore which were arranged to occupy theentire space cfa window and lthereby to screen the opemngs of either the upper or lower sash or of both; but no such screen has had the additional lconsiderable advantage of being adjustable to suit openings ofthe lower sash while leaving the upper sash entirely unobstructed. It is a matter of common experience that the presence of a screen in front of a window darkens a room very materially and consequent-ly it is of great advantage to have' a screen adaptable to close only a portion of the Window. At the sameI time'it is important, especially during those seasons of the year when screens are most needed,

that the Window be open at the top to permit proper ventilatiomhence the deslrability of having a screen to close an opening of t-he upper sash, It is evident therefore, that t-he above suggested adjustments contemplated b certain features of thls invention, not only c mbine all the advantages hitherto separately accessible in various .types of'screens, but also present features of It has been a'well-known expedient, particularly in connection with screens wound on spring rollers, to have the end edge of the screen attached to the bottom part of the lower window sash, so that when the latter is elevated the screen will be drawn up with it. This arrangement has various disadvantages. For example, in the case of a heavy window, if it he lifted hurriedly it will acquire considerable momentum, sufiicient, if the screen should catch or its unwinding should be obstructed, to tear the screen or to break some part connected with it. Furthermore the necessity for attaching a screen to the lowes sash in the lnanner described, when this is the only provision for adjusting the screen, precludes the adaptability of the screento the closure'of the upper vsash or the entire window if desired. `It: is preferable, therefore, though not indispensable, that the screen be adjustable independently of the sash, and a convenient embodiment of this invention supplies this preference.

arious advantages other than those pointed out are supplied by this invention and they will be apparent .upon an examination of the illustrative embodiment 0f the invention hereinafter described.

In' the accompanying drawings, Figure 1 is an elevation of a two sash window viewed from the interior of the room, and having associated with it a convenient embodiment of the invention, the screen Vbeing shown therein adjusted to close the extreme opening of the lower sash; Fig. 2is a vertical section on the line wof Fig. l showing the screen in inoperative position; Fig. 3 is an enlarged. detail of the lower part of Fig. 2 showing the screen adjusted t'or a slight opening of the lower sash; Fig. 4 is a detail of certain parts shown in Fig. 3 omitting other parts for the sake of clearness; Fig. 5 is a horizontal detail section on the line g/-fz/ of Fig. 4; Fig. (3 is a section on the vertical plane indicated by a line a, in Fig. 3; Fig. 7 is a detail section of a screen roller shown in section also in Fig. 3; Fig. 8 is a front elevation of the cross 4head to which the end edge of the screen is attached; F ig.` `9 illustrates 4a convenient method for preparing the screen for attachment2 to the cross head; Fig. 10 is an end elevation of sash 4 and a lower sash 5. A screen 6 is attached at one end to a roller 7, which roller type.. The roller 7 is journaled at .its opposite ends in brackets 80, one of which is preferably slotted in the well known manner to permitv removal of the roller when occasion requires. screen wound upon it, is disposed parallel to the front of the windovw and preferably vupon the sill, the screen unwinding from that side, of the roll adjacent the sash. When the' screen is unwound its lateral edges engage guides 8 arranged not only to 'uide the screen in its pro er path during adjustment, but also to e ect a snug closure with the edges of the screen. A practicable y form of guide is shown in cross section 1n Fig. 5. It is composed of al single piece of sheet metal bent to present a fiat attaching portion 10, by which the guide is secured to the side of the window.- frame, and two oppositely disposed guide anges 11 and 12 spaced slightly apart' to provide a guide channel The guides 8 just described are duplicated on opposite sides of the window frame. The extremity of the flange 12 is preferably bent at an angle to provide a positioning flange' 14 for purposes hereinafter explained.

- They end edge of the screen is preferably secured to a cross-head 15, to which is attached a lifting cord 16. N

overa pulley,-it .may be a self locking pul1ey,-at the top of the window.

' Referring to Fig. 10 the upper portion of the cross head is bent into cylindrical forni to supply a seat into which` a key rod 18 'may bejinserted endwise, said key rod be? ing then encircled bythe end of the screen o r some material attached' thereto. vThe lower edge ofthe cross head has a curved the screen and press it toward the window sash. The-cross head is preferably made of `flexiblel sheet metal and the pressing por` tion 19 tends by its "own elasticity to press against the screen. It is assisted in this oflice by the action ofthe lifting cord 16,

which is attached to the cross head (see Fig.

3) ata point displaced laterally from the.`

axis of the key rod 18. Thus, when the cord 16 is drawn taut to elevate the screen it tends to Arock the cross; head on the key rod 18 asa fulcrumand thereby it assists in holding the pressing portion 19 snugly against the screen and in holding the latter may be conveniently of the` usual springl The roue/r 7 with the 13 to receive the edge of the screen.l

The cord passes l pressingportion 19 yadapted to 'rest against against any part with which it 'is desired'to make closure. The spring of the roll 7,l which opposes the pull of the cord.16 with considerable force, contributes also. to the v operation of the pressing portion'19. 70

When thescreen is adjusted to close an opening of the lowerwindow sash, the cross head 15 lies adjacent the botto-m of'the sash and the pressing portion 19 holds the screen snugly thereagainst. To coperate with the pressing portion 19 when the screen vis adl justed to close an opening of the upper sash, an apron 43 is provided. As shown in the drawings for purposes of illustration vthis apron 43 is merely a strip interposed between the sides of the'window frame and arranged to register vertically with the in; `ner faces of the lower sash. Obviously, the \form of this apron'is immaterial and it ma. be replaced by any practicable device whic will serve the saine purpose. The curved seat 17 of the cross head and the pressing portion 19 project, as shown in Fig. 3, somewhat beyond the plane of the screen and are preferably of such extent as to bear at their opposite'ends with easy sliding lcon- 'tact'upon the positioning flanges 14 (see Fig. 5), thus serving to hold the screen against lateral displacement and to guide it l in its proper vertical path: 9,5 The body portion of the cross head 151.l vwhich intervenesrbetween the curved seat 17 and the pressing portion 19 is extended j endwise at 'each end'to. provide a win 20 (Figs. `1 .and 5)which enters a gui ing channel 13. The-width of the screen 6- is such that its lateral edgesextend into the guiding channels 13, which are arranged to y r fit snugly over the wings 20 with the screen edges attached thereto. j The screen may be secured fto the cross'. head in any practicable manner, For -example,.the screen itself may -be sewed lor otherwise fastened to a piece of fabric-21, the fabric being vpassed around the ke rod 1-10 '18 and thereafter folded upon itsel 'and sewed,the key rod being then inserted endwise in the curved seat 17. The edges of the fabric'are preferably cut'to present flaps 23 (shown in=Fi gs.. 9l and 10) which fold over 115 the wings 20,- and are secured in place in any'` desired manner. `Thevend of the screen opposite the cross head may be attached to a lfabric cover 27 encirclingthe roller 7. Adjacent this point -of attachment the roller is preferably supplied. with a longitudinal groove 28, both for convenience in sewing or otherwise fastening the screen, and to receivethe increased thicknesswhen .the screen is wound upon the roller. y ..1125 The .roller 7 vis inclosed'in a casing 29, dev-A tachably supported on the window-sill. The casing 29 has al vertical front wall 30,'resting at its lower edge upon the sill -and a top wall 31 extending over the roll 7. The op- 130 posite ends of the casing 29 abut snugly against the guides 8 on the sides of the Window frame and thereby form a tight closure. The inner edge of the top Wall 31 of the casing 29 is rounded somewhat to supply an easy bearing for the screen as it is adjusted. The brackets 8O are attached to the Window sill; and a flange 33 (Fig. 3) carried by-the casing 29 rests against the brackets and serves to support the inner edge of the casing. The extreme opposite ends of the edge 32 are trimmed away so as to form latches which, as shown in Fig. 11, engage the lower extremities of the guide flanges 12. Said flanges 12 are cut away at solne distance from the bottoms lol" the guides 8 to provide t'or this convenient mode of securing the casing in place. The casing may be further locked in position by means of spring catches 36 arranged to engage a foot 37, as shown'in Fig. 2. To permit compactness inthe arrangement of the parts it is preferred to recess the roll 7 (as at 38, Fig.

12) to receive the projecting bearing por` tions 39 of the brackets 80.

.When the screen is rolled up upon the roller 7 the cross head occupies substantially the position shown in Fig. 2, wherein it is inclosed within the casing 29. lWhen in this position the cord 16 may be detached from the cross head and removed, if desired, leaving the window entirely free from any obstruction. When it is proposed to screen an opening of the window, pulling of the cord 16 will elevate the cross head, and when the latter reaches position adjacent the bottom of the lower sash, the pressing portion 1f) of the cross head will press against the sash and make a tight closure therewith. The screen may be held in this adjusted position in any convenient manner,for example, as already suggested, by a selflocking pulley acting on the cord 16. If it be desired to open the upper sash of the window, the screen may be further elevated to such a position that the pressing portion 19 will form a closure with the apron 43.

It is to be understood that the specific embodiment of this invention above described, has been disclosed herein for illustrative purposes only, and that said embodiment is susceptibleof`various changes and modifications (such as will appear to those familiar' with the art) which are to be construed as included within the proper scope of the invention as it is defined in the subjoined claims. It is not essential that all of the features ofthe invention be used collectively,

' as in the instance of the illustrative embodiment described, but they may be used in various combinations and sub-combinations.

There Words denoting direction, position and the like are employed in the subjoined claims, such Words are to be construed, where the context permits, as words of relative designation and not limitation, since obviously relative direction, relative position and the like are alone of importance. y
