. One of the main objects of this invention is to provide an improved window screening device which .is automatically operated by the opening and closing of f the window; and which is readily attachable to the window frame and to the sash, and is likewise easily and quickly detachable therefrom to facilitate cleaning the window sash and sill, and for storing away the device in fall, without operating any screws or securing elements or marring. the frame and without the use of any tools. r

Another object of this invention is to provide `an automatically operating screening device which consists of only a `few members that are readily connectable and mountable inposition in .the window frame, and which are likewise readily removable therefrom, and which preferably consists of a pair of guide members detachably connectable `to the window jambs, also an operating mechanism including the screen and which is easily connectable to said guide members and to the window sash, by merely setting the screen equipped mechanism into place between said guide members, and is similarly readily removable therefrom. l

A further object of this invention is to provide `such a screening device which comprises a housing carrying a screen therein and provided with f means whereby the outer end of the screen automatically becomes operatively connected to the lower bar of the window sash bythe act of mounting the device in place in the Window frame, so that the screen will move along with the sash; and in which devicethe screen has its outer end automatically connected to the` housing when the sash is closed, and the housing with the screen can then be readily withdrawn from the window frame and sash when the `latter is in its closed position. r

Another object of this invention is to provide such a screening device comprising an improved screen roller wherein the parts can be easily put together, to save labor and provide for economy in its manufacture.

These and various other obects and advantages are attained with this invention, as will become apparent from the following description, taken in connection with the accompanying drawings in whichthis invention is illustrated inits preferred form; it being understood that various other arrangements and forms -of construction may be resorted to for carrying out the objects I u andpurposes of this invention.

In the drawings:

We have illustrated our invention inthe draw ings in the preferred form of construction, comprising a pair of side members II and I 2 which are detachably mounted on the pair of jambs or side members I3 of the window frame; and the screening mechanism I4 which includes a casing or housing I5 carrying therein a roller I6 provided with a screen Il, `all combined asa unit. Said housing bears on the; lower member orsill i8 di" the windowframe, and the screen I1 is releasably attached to the lower bar la of the window sash I9', so that the mechanism isreadily mountable in position between the guide members Il and I2 and is readily removable therefrom. r lower window opening, and can similarly be applied to the upper opening.

l The two side members l! and I 2are economi-` cally constructed from strips of sheet metal formed substantially `into the shapes indicated in the drawings, and each member prerferablyhas its parts made into one integral member, tov effect economy in construction; altho each may be formed from one strip of metal or from several strips welded together. l' i l The side member III comprises an attaching portion or bar 20 adapted to be attached to jamb I3, and has. spaced guide plates ZI and 22 extending atan angle therefrom, and for a sub- It is Shown installed `for screening the stantial distance, so as to guide a substantial marginal part of the screen in the included chan-'- nel'or space 23 therebetween, to take care of variations `from standard widths of window frames.

v The lower end of plater 22 is bent inward providing a lip 24 to engage upon housin-g I5; while a bracket or plate 25 extends from and is integral with the lower end part of member I I, adapted to engage one end of roller i6, and has a lower inturned end or lip 26 toengage under housing I5,

thus holding one end of said housing between the lips 24 and 26 and said bracket 25. Said bracket plate 125 has an aperture 21 therein to receive the round end'portion 28 of the rod 29 which extends thru the roller I6.

The side member I2, like its companion member II, comprises an 4attaching portion orbar 30 to be attached to the opposite jamb I3, and includes spaced guide plates 3| and 32 `extending at an angletherefrom, for guiding a Substantial marginal part of the screen in the included channelV 33 therebetween; The lower end of plate 32 is bent inward providing a lip 34 to engage upon housing I5, and an integral bracket plate 35 extends i'rom the lower end part of member I 2, adapted to engage the end of roller I6, and has an inturned lower endproviding a lip 3S to engage under the housing I5, thereby holdin-g the end Aof the housing between saidv lips3li` and 36 and said bracket 35; The bracket 35 has a slanting slot 31 therein to receive the flat end part 3B of the rod 29 of the roller; so that the housing 'with its roller and screen can be readily installed between the sid-e members by sliding part 3B downwardly in slot 3l, and thus holding said side members and the mechanism in position and preventing any accidental sliding away or withydrawal of the mechanism.

The bars 23 and 38 of members I and I2 have each a notch or opening All provided at the `upper end and have an aperture or opening A lnear the lower end. A screw or headed element 42 and a pin 43 are secured toleach jamb I3, and the members II and l2 can then be readily mounted in position by simply tilting the members, as indicated in ldot-and-da'sh lines at the top of Fig. '3, so that notch Mi engages screw 42, and the lower part of the member is pressed to the jamb i3 to bring pin 43 in aperture 4I, said side member being thus held by the head of said screw v42.l .The housing is then slid into positionbe-y tween said side members, thereby securing said 'members and thev screening mechanism in position inthe frame, as stated above', andv likewise' facilitating the vquick and easy withdrawal of the entire device in the form of three members or units.

i The screening mechanism, `which comprises the casing i and the roller I5 with the screen I1, is arranged to be installed and removed as a unit from the side members II and I2 on the 'window jambs and from the window sash. The housing has a pairjofcaps 45 on its two ends closing the ends andbeing adjustably mounted kthe widths of the frames; and each cap contains a suitable aperture 48 thru which the end por- 'tions 28 andil project. 70

The roller i5 is economically constructed from a strip of sheet metal curved so that its side [edges remain slightly spaced and provide av longitudinal slot 5i). A pair of heads .or head memt bers 5I are pressed i,into the ends of the roller 7'5 and a similar member 52 is forced into the intermediate portion thereof, each member having a tongue 53 which engages in said slot 50, to hold said member against turningy therein. The rod 29 extends thru openings in said members and it has a coil spring 54' thereon having one end secured in the rod and the other end preferably secured in the intermediate member 52, as best shown in Fig. 9. The rollerhas ycleats 55 stamped outward thereon which are hooked to the inner endet" screen Il and are then bent down onto the'roller to secure the screen in place thereon, as best shown in4 Fig. 4; and the screen I'! is thus automatically wound on vand operated by the roller in the casing, and is also detachable from the cleats.

A reinforcing and attaching member 56 is secured. to the outer end of the screen. This member is preferably in the form of a doubled strip of sheet metal including the two portions 5l' and 58 with ythe latter having its lower edge portion 53l turned inward and clampingthe bent edge portion of the outer end of screen I'I therebetween. Securing velements may further be used for positively pressing and holding portion 5l against the screen and the bent portion 53', as best shown in Fig. l0, to secure the screen positively therein. Said member 56 is provided with key-slots E! yeach having an enlarged lower portion 5i v adapted tc pass readily over the head E2 of a 'headed 'member 52 which is mounted on the sash iQ, preferably by securing it to the lcwer'attaching part 63 of a handle S3 fastened on 'the bar iSof the by suitable means, as best shown in ll. Said member 55 is furtherprovided with hooks 65 on its upperV end whichengage` in openings 66 provided in the upper part'of casing I5, as best shown in Fig. 8. Y

With this construction as disclosed above, the

side members II and i2 can be readily set intoyl place on; the window jambe i3, and the mechanism I4 can thenbe readily placed in position between said members` ii and I2, to mount the entire device in the proper position. The headed members t2 on the window sash and the slots G I` on the connecting member 5E are so placed that whenthe sash is closed the enlarged portions i of said slots will be in line with the heads 62' of said member, so as to enable convenient withdrawal of the operating mechanism from the window sash and frame. Whenever the sash is raised said members t2 will engage inthe narrow upper parts of slots 5I and will then carry along the attaching member 56 and unrcll the screen for screening the window opening; and when the sash is fully closed said heads B2 will again be in line with the enlarged portions E i as stated above` The hooks 55 engage within openings 55 when the window is closed, so as to bring said enlarged portions iii' in line with said heads 62'; butl as the sash is raised and members t2 lift the attaching member 55 and the screen, it also lifts the hooks 65 from said openings 6% and from the casing; yand will again enter them therein as the window sash is closed. This device can thus be readily removed from the window and frame, by simply lifting said mechanism away from the side members and then sliding said `members away from the window frame;v andthe device likewise can be easily replaced, without the ,use
