' tjoiaims. 01."15e-3er` Aan attaching clamp frictionally engaging the irame of a window particularly a'metal window with the outer portion of the clamp forming a spring type weather stripping and the inner portion of the clamp forminga channel to hold the screen or screen `frame in the proper position.

Another object of the inventionfis the provision of an improved screen guide or retainer of simple and economical construction which may be attached to or removed from a window frame in a simple and convenient manner without the use of special tools Vand without the'necessity of employing a skilled'mechanic and which may, ifdesired, also serve as a weatherstripping to seal the joint between' the' sash yand window frame. i p

Among other objects is the provision of an improved screen guide and retainer of the above character which is especially suited for use in connection with roll screens, which provides a tight connection between the edges of the screen and the screen guide so as to prevent insects from entering at these points; and which is provided with an improved roll screen mounting and `also releasable locking mechanism whereby th roll screen may .be releasably held in lowered position.

For a fuller understanding of the invention reference should be had to the accompanying drawing in whichi Fig. 1 is a front elevation of a screen retainer embodying my invention showing itin assembled relationship attached/to a window frame;

Fig. 7 isa sectional viewin thedirectionof the-arrows on the line 'I-l-of Fig. .1.. In the accompanying...drawing my-impr.ovedfl `with an inwardly projecting flange known as a weathering as indicated at It as in the preferred screen retainer which is indicated generallyat Illvis illustrated as applied to the met-al frame II of a easement windowv in which the sash is indicated by numeral l2. While my invention is particularly adapted for use in connection with steel frame' windows of the easement type it should be understood lthat it may be used in connection with sliding or pivoted windows made either of wood or metal.l However, in this conn'ection` the window frame should be provided embodiment of my invention the screen retainer is held in position by being clamped to the weathcring.

`My screen retainer is preferably formed of vmetal and is lprovided with two similar parallel vertically disposed side members I5 adapted to be positioned on opposite sides of the window Aframe :and each having a channel shapedclamping portion IS' which is resilient in -construction and of proper size to tightly engage the weathering I andv thereby retain the device in position. -The outer side of the channel shaped clamping member is curved outwardly as indicated at ITI and is made of spring metal and is offsuch a length as to tightly engage the sash when in closed position thereby serving as a weather strip to provide a tight sealbetween the sash andframe. v

VOn the inner oropposite side each vmember I5 islpreferably formed as shown intova channel portion Iii which faces the window opening and serves `as a guide and retainer `for. the lateral edges of the screen. The free end ofthe channel portionwl is preferably bent towards the clampingportion as shown so as to insure a relatively Vclose t between thescreen and channel thereby preventinginsects :from entering along the edges.

The two members l'arev of similar construction butvare 4arranged in opposite confronting relationship as shown, the clamps Iii being attached to thev weathering on the two sides of the frame with the weather strips 'I i disposed on the outside andthe channel guides I3 disposed on the inside.4 When used in connection with a roll screen the roller should be mounted in some suitable'manner adjacent the upper ends of the two members I5. Thus I may 4provide a bracket 20 at the upper end of each member I5 and in which the' spring roller 2l is mounted in conventional manner, the spring rollerserving to support the roll screen 22. i

. The ,brackets'il areof suicientresilience to ..permitinsertion and removal @rollen/When the roller is in position it will be appreciated that it will effectively retain the upper portion of the respective clamps I5 in engagement with their weathering ilanges vand protect the members I5 from accidental displacement. So as to facilitate the introduction of the screen into the guide channel I8 I preferably terminate the inner wall of the channel a `short distance vfrom the top of each member I5, bend it outwardly at ya slight angle, and roll the upper edge thereof as indicated at 23 thereby reducing friction and wear at this point.

As shown most clearly in Figs. 1 and 2 the screen is of suicient width to extend into both channel members I8. The lower end of the screen is introduced into the top of the channels and is then pulled downwardly to its lowermost position. It will be lappreciated that the side edges of the screen are effectively guided and retained in -position by the channel portion I8 and due to the relatively small clearance at these points insects cannot enter around the side edges.

Across the top of the window frame I provide a suitable mem-ber indicated generally by the numeral V24 for preventing undue clearance at this point and also `for providing a weather strip betweenl the sash and frame. The member 24 consists of a channel `shaped clamping 'portion 25 somewhat similar to the clamping portion I6 and having a spring metal outwardly curved weather strip 26 similar to the weather strip I'I and adapted to engage the upper edge of the f window sash and seal the space between the sash and frame.

Vshifting inwardly and also providing a weather strip and suitable releasable locking means for releaseably holding the screen in its lowermost position. channel shaped clamp 29 engaging the weather- ...ing ilange I4 at the bottom of the window frame and is formed with an inwardly curved spring The member 28 is provided with a metal weather strip 3!) similar to the weather strip I'I and adapted to engage the sash when in closed position. On its inner side the member 28 is provided with an enlarged upwardly facing channel portion 3| which is adapted to receive the bound lower edge of the screen 32 when it is in lowermost position. At its central portion the front wall of the channel member 3l is provided with a circular aperture 33 having a restricted throat 34 communicating with the upper edge.- Adapted to cooperate with the' aperture -Y and throat 33 at 34 is the handle member 35 formed on the end of stem 36 pivotally mounted on the lower portion 32 of the roll screen. will be seen that stem 36 is of elongated cross sectional construction so as to be of greater dimension in one direction than another. By turning the handle so that the dimension of greater length is disposed in vertical position the stem may be inserted through throat 34 into i aperture 33 then by turning the handle through an arc of 90 degrees the stem is prevented from accidentally releasing from the aperture, In this way the roll screen can effectively be retained in its lowermost position.

As a convenience in assembling Vmy improved member 28 adjacent its two ends to the lower portion of the two members I5 as by means of pins 3I- Thus the two side members and the lower member 28 form one unit which may be readily assembled on the window by first pivoting the upper ends of the members I5 inwardly as shown in dotted lines in Fig. 1 then attaching the channel clamp 29 to the weathering at the bottom of the window frame then pivoting the two members I5 outwardly to vertical position with the channel clamps I6 in engagement with the weathering flanges at the two sides of the frame. The member 24 at the top of the frame may be placed in position either before or after the members I5 and 28 have been assembled yas described. Thereafter the roller 2l with the screen mounted thereon is mounted in the brackets 2E! and the screen may be lowered and raised as desired.

It will be seen that the roller 2| prevents the upper ends of the members I5 from accidentally shifting 4inwardly and the member 28 prevents the lower ends of the members I5 from accidentally shifting inwardly. It will also be seen that there is nosubstantial clearancebetweenwthe sides, top and bottom of the screen and the screen rei'lainer when the screen is in lowermost position. Itl will also be seen that my improved weather strip will form an eiTectiVe seal between the sides, top and bottom of the sash 'and the window frame. .Y Y Y It should of course be understood that many modications may be made in the illustrated and described `embodiment of my invention,4 'I'hus the screen retainer may be used in association with other types'of screen and may also be apy plied todiierent types of windows. It should also be understood that different releaseable locking mechanism I or releaseably locking the screen in lowermost position may be utilized and that diierent types of mountings for the screen roller maybe provided.
