The object of my invention is to provide a rollscreen installation for steel easement windows of simple, durable and comparatively inexpensive construction.

5 More particularly, it is my object to'provide an installation wherein a rollscreen may be installed upon a st eel easement window employing parts of such standard steel casement as a means for mounting the entire rolly v screen thereon without the use of any additional fastenin elements or the like.

A further ob]ect is to provide an installation wherein the rollscreen casing may be mounted upon. supporting elements, which supporting elementsv are frictionally supported upon parts of the steel easement, and where such supports provide guide means for the side edges of the screen and at the same time serve as a weatherstrip feature between a portion of the easement frame and the window sash thereof.

A further object is to provide a head spacer element and a sill spacer element adapted to be frictionally mounted upon the head and sill portions of the easement frame and to serve as filler elements between the two saporting elements forming a part of the ro screen installation. 4

It may be here mentioned that standard steel easements are provided with a marginal flange around the window opening,and that the hinged sash member isnormlally arranged tov abut against themarginal flange. The point where the-hinged sash member abuts againstthe flange is normally referred` to as the ,meeting bite of the sash with its casement. In my installation, I provide'a plurality of members which frictionally receive n the marginal flange, whereby the parts of my rollscreen installation are securely held in position relative to the easement window, and

1t is upon these parts that I mount a rollscreen casing and other parts necessary to rovide a complete rollscreen installation an structure for a steel easement window;

' A further andmore specific object is to pro- Y vide supporting elements having oppositely opening channel portions or grooves, one to receive theelside or jamb a'nges of the case- .50 ment and theother to receive a screen guide or the Side edges of the Screen asnsjthe two channel portions being arranged in" spaced' parallel lanes.

A furt er object is to provide a rollscreen casing adaptedto be supported by a air of supporting elements, having portions endable'upon the casing itself for retaining the casing in position, the casing itself serving as a spacer for normally holding the supportv ing elements in spaced position and in installed position upon the easement frame.

It is also an object of my inventionto provide a4 rollscreen installation wherein the parts can be assembled without the use of any special tools or the like and without the use of fastening means, employing certain parts of the present standard steel easements as a means for mounting the rollscreen thereon, the installation being neat and pleasing in appearance and in no way interferin with' the plaster j ambs or the beauty alor ed by steel easements themselves, the screen being mounted within the home or building, thus' making neatness .in appearance an essential ob'ective. Y I ith these and other objects in view, my

invention consists in the construction, arrangement and combination of the various parts of my rollscreen installation for casement windows, wherebythe objects contemplated are attained, as hereinafter more fully set forth, pointed out in' my claims, and illustrated in the accompanying drawings, in which:`

dow where the plaster header of the wall is of the kind shown in Figure 2..

In the accompanying drawings, I have used the reference character A- to indicate generally a building wall, which ma be of either wood or brick construction an coated on the inside with -ordinary plaster 10.

- The building wall A includes a window opening B, in which is mounted a steel casement and sash C. vThe steel easement is of the standard kind andincludes a easement frame 12, having an inwardly extendin marginal flange 14. The flange 14 may reerred to as a marginal or inwardly directed dangle around the window lopening defined by t Casement itself.

An out-turned marginal flange 16 is also formed as part of the easement frame and restsvagainst the building wall on the outside thereof, as clearly illustrated in 'section in Fi 2 4of the drawings.

window sash 18 adapted for hinged movement relative to the easement frame.

On the inside'of the flange 14 is mounted a stop or plate 20 adapted to coact with the cam locking element 22 carried by the win-.-

dow sash 18. A handle 24is employed for operating the cam member 22. It may be further mentioned that the stop or plate 2O has an inclined face, so that operation of the handle 24 will cause the parts to engage for retaining the window sash 18 in closed position.

The parts just described are of ordinary construction as now found in practically all of the so-called standard steel easements.

For purposes of further explanation of my rollscreen installation, I use the reference numeral 26 to indicate the two sides or jamb ortions of the peripheral flange 14. 28 ingicates the flange atthehead of the frame, and 30 the flange at the sill of the frame.

My rollscreen installation is adapted to c0- act with the inwardly directed flange 14.

My installation inc udes a pair of supporting elements D. Each supporting element is formed to provide a pair o oppositely opening channel portions 31 and 32. The channel portions 31 and 32 are s aced apart and connected to ether by a we or the like 34. In the actua construction of the supporting elements D, I employ one (piece of metal, which is so formedas to provi e a complete channel portion 31 and one wall of the channel por- -tion 32. The other wall of the channel portion 32 -is formed by another piece of metal larranged in spaced relation to one wall of the ithin the easement frame is mounted a rection, are parallel to each other, and spaced apart.

Each supporting element includes an u wardly extending li 36 formed upon t e inner wall of he cliannel groove or portion 32. v

The channel portions 31 are arranged to receive the jamb flanges 26 of the easement frame. The channel portions frictionally receivesuch flanges 26.

The outside Wall of each channel portion 31 ispositioned'between the meeting bite of the window sash and the casement frame, thus serving as a weather strip feature between the easement frame and the sash thereof.

It will bev understood that the parts just described, which form the supporting elements are of sheet metal, and thus inherently la weather strip feature.

A rollscreen casing 38 is used, and such casing is disclosed in my Letters Patent No. 1,730,649, issued October 8, 1929.

One corner of the casing as at 40 includes a notch or cut-out portion. This portion is in reality a continuation of the discharge opening 42, through which the screen may vbe withdrawn from the casin' as will be hereinafter more fully set fort l It will be noted that the bearing members 44 of the casing are spaced inwardly a slight distance from the ends of the casing. The outer wall'of the casing 38 as at 46 is arranged to slip into the upper end of the groove or channel portion 32. The casing 38 is thus retained in position relative to the two suporting elements D. The lip 36 is thereafter ent over and brought into engagement with the upper side of the casing 38.

The assembled position of the casing and its supporting member for each end is clearly illustrated in Figure 4 of the drawings.

Within the casing 38, I provide'a rollscreen assembly E, which includes a spring-actuated roller 48 and a screen 50. The lower free end of the screen has a stiff binder 52 mounted thereon which has an inwardly directed finger ledge'54.

The screen is permitted to pass out of the casing 38 through the discharge openin 42. Within the channel portion 32 of eac supporting element D, I mount a screen guide or track 56. The track 56 includes a flat fastening flange adapted to telescopicall fit into the groove or channel 32 and to be rictionally retainedtherein.v The guide or track y provide with a Slllii` 0 `wise thereof, anditis-throu h'this slit opening that the side edges of t e screen 50 are i received. i

- Theretainingelements may be employed l y uponthe side edges of the screen, and are -norinallyreceived `within the guides or tracks `56. i The guides Aor tracks 56 are positionedbelow the'screen casing 38. Friction shoes for blocks 60 are `fastened to the .endsfof the binder 54 and travel within the guide tracks 56. Locking elements 62 are carried Vby the aort po ing) tracks and coact with thetinger ledge 54 when the screen isin withdrawnaposition forretainin it in such osition a ainst the ac-v tion of t el spring ro er assem ly 48.

It will be noted that the rollscreen assembly including the casing, tracks and the like, are all mounted and supported upon the supelements D. The supporting ele'- ments are in turn frictionally retained on the side or jamb anges of the easement proper..

A head spacer element 64 is secured to the head ange`28 of the easement 'and spans or `iills the distance between the easement' and the rollscreen as well as between the two supporting elements D.

The head spacer element is formed with an upwardly opening channel portion 66, which receives the downwardly extending head iiange 28.

A down-turned` marginal iiange4 68 is f formed on the inner edge of the spacer element 64 and this is in contact with the outer wall of the casing 38.. l

A sill spacer element 70 is also provided and it in turn has a downwardly opening channel groove 72 to normally receive the upwardly extending sill flange 30. The spacer element 7 0 is positioned between the two `snpporting elements vD and prevents their move ment toward each other, and is formed with wise provide a a portion 74 normall arranged to be positioned just-.below the oweredge of the guide tracks 56. i

It will be 'noted' that the sill spacer 70 is positioned a short distance up above the ower ends of the supporting elements D.

The s acer elements 64 and 70 revent removal o the supporting elements and like# y-tight joint, due to the fact that 1t isnecessary to have'the screen casing and guide tracks therefor spaced inwardly a slight distance from the inner face of the leasement frame. y f

Practical installation The practical installation of my rollscreen installation may be briefly described as folows: .o y V The steel casement-window is placed in position in fthe ordinary manner and forms a standard.irtion`orV part of the `building structure. vThe problem of screening the window then presents itself.` 1 u It is impossible to havea `screen mounted .onthe outside of a easement window, due to the `peculiar nature of the Veasement itself in that `the window sash opens outwardly an is of the hinge mountedtype.

My screen is mounted on the inside of the easement and VI take one of the pair of supporting elements and fit itinto the notch 40 of the casing, and then place it over one of the side'jamb flanges of the Casement. The other su porting element is then fit into the other si e of the casing. The lip 36 is bent over. The casing is arranged at an an le while the installation is taking place. for illustration of same.)

A rubber hammer may be used for tapping the members in position or they may be simply pushed under slight pressure to position.

The supporting elements are thus frictionally retained upon .the easement without other fastening means..

The head spacer member or element 64 is then forced onto the head iiange 28'of the easement, with its ends positioned betweenV the two supporting elements D, and particularly between the two channel portions of each supporting element. (See Figure 10.) r1"hey sill spacer element 70 is forced under pressure onto the sill iiange 30 and likewise arranged so that its ends are positioned between the two supporting elements D.

After the casing is in position and the two supporting elements in engagement with the flange of the easement, the entire structure is in complete relationship relative to a steel Casement Iand completely mounted thereon, without the use of any peculiar'faste'ning means or elements.

( ee Figure 9 The rollscreen installation can lbe easily and quickly removed if it is desired for any cause. y y

My present rollscreen installation has been in actual use and has proven successful in such use.

I may here mention that after the complete l installation is had, then the entire peripheral iian'ge 14 of the easement window is covered by the channel portions of the spacer elements yand supporting-elements, and a weatherstrip `:feature is provided, lextending around the easement frame adjacent the point where the window sash engages therewith.

It is necessary to incline the casing .and

one supportin element as illustrated in Figure 9, due to t e fact that the plaster header above the easement is quite close to the upper rail of the casement. If plenty of space is had, then the rollscreen can be installed b lacin both supporting-elements on the si e amb anges and thereafter mounting the k` thereon. While I have 'shown the supporting elements as fabricated from several pieces, it will of course be understood that it might be formed in a rolling machine of one piece of metal.

Some changes maybe made in the construction, and arrangement of the various parts of my rollscreen installation for casement windows without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.
