' io they are associated, but diiiiculty has usually been found in providing for the proper sup-V port or the screens When-extended over the openingsso that -in the case `of porches and verandas they yWill be effectively held against undesirable .flapping or distortion by Wind, and in' the case off indoor openings against inadvertent movement trom their closed positionssueh as renders the ordinary hanging korcurtain inadequate for its purposesV This invention, therefore, proposes to overcome "the objectionable features ordinarily present in .ther use of `screens as heretofore commonly employed for the said purposes, and to provide a simple and .effective method ofinounting screens in openings so that they may loe` readilymoved into and out of operative positions and at, the Ysame time Whenin operationbe held laterally in such kmanner thatthey will afford ample protection against the passage of Wind or,Y

rain through openings screened thereby further object is to eiiect the incorporationV of the edges of such ascreen in the,

frame ot the openingV and the retention ot" such vedges therein .whereby the passage of Wind or rain therearound Vis prevented or minimized, and whereby tension is exerted on the curtain oii'ering a resistance to theV warping` effects of Wind pressure thereagainst.

Still Jfurther objects subsidiary to or resulting from the aforesaid objects, or from the-construction or operation of theinvention as it may be carried into ellect, Will be.-

come apparent as the said invent-ion is herev inafter further disclosed.

In carrying the said invention into effect, I may utilize hollow or tubular posts7 as the i n lateralinembersofthe frame ot the opening tobescreened, and house a iiexiblescreen upon a roller enclosedvin a suitable housing at one end of the frame, means being pro- 1 Avided for the operation of the roller such as the equivalent ot means commonly employed .in the spring rollers of blinds The posts are formed with opposed longitudinal slots in which the marginal portions of the screen are guided and ,through which such `inarginal portions are vadapted to extend `into.

the hollow posts, these slots being provided with guide rails onV the lmiieisides of Which suitable retaining means such as rings car-` ried by the margins ot the screen ride. lOne of these sets ot rails `may be movable trans` versely 'et itspost and relativetothe opening so that lateral tension maybe exerted on the said screen when in its drawnposi- .tion7 adjustable resilient means being .em-

ployed to effect the retractio-nof such rails i andthe provisionof such tensionuon the.4

1 .indicates a 'structure lprovided `With spacedk posts 2 and 3, these postsbeing hol-` low oir-tubular and provided with opposed slots t and 5 respectively extendingflinthe direction of. their length. At the topfot' the opening is a cross `piece 6,'and at the bottom a holle-W sill or housing7, the .upper part of which is provid-ed With a ,slot.8 extending betweenthe lower ends ofthe aforesaid' slots 4 and 5 in the holloivposts. This housing accommodates a roller 9 uponwvhich a blind, screen or curtain 10is' adapted to be Wound, the said roller beingprovided atfone end with a pulleyll from which aweiglit 12 is suspended by aflexible member 13 so that ,the said Weight will effect the .rolling of the screen4 .upon the said roller as Will be quite.

apparent. Without further description.

` The outer end of the screen f10vis provided with a cord 14 passing around a clutch roller 15, whereby the 'curtain may be adjusted relative to the opening and secured in adjusted positions as Will be also Well understood.

F igui'e 2 is a fragmentary elevation ot' a It will be seen that the marginal portions of the screen extend substantially into the slots of the posts, the screen being wider than the opening,` and these marginal portions are provided with rings or projecting members 16 which are engaged by guides or rails 17 and 1S within the slots el. and 5 respectively ot the said posts so that the marginal portions ot the screen are prevented trom being withdrawn laterally troni the slots and whereby the .screen is guided in its opening and closing movements.

lVhen the opening is closed by the screen, it will effectively prevent or minimize the passage ot' wind or rain through the said opening more especially z the marginal pertions o'lf the screen are enclosed by the posts in the manner described, but an objectionable feature which is quite common to tlexible screens, particularly when theyv are made of textile materials which are of a flexible or more or less tlaceid nature and in some cases liable to stretch to some stent upon continued use, is the 'laet that such screens have an objectionable tendency to flap or warp under the influence ol wind pressures or to be otherwise bulged or varied in their prescribed relation to the opening which is screened. This l elteetively overcome by movably mounting the rails 1S in the post 3 and applying lateral tension to the screen through the said rails. In the example illustrated this is accomplished by niounting ther rails 18 lctween the arms lf) ot U-shaped members 20 housed in the said post Sl, these U-shaped members being attached to rods 2l through which springs Q2 effect a pulling torce upon the said U-shaped members and incidently upon lthe screen through the medium ot the rails 1S.

The said rod is provided with an adjustable abutment 225 adapted to eng ge a suitably arranged stop 24- to prevent the movenient o'lt the. said rails tor 'ardly ot the said opening to an undesirable extent, and the U-shaped members 2U may yieldaliily engage the inner sides ot the posts so that they will Jfrictioiiably damp or reduce the too 'lree actuation ot the said spring operated members where such damping thought necessary or desirable.

he tensional arrangement permits ot' the operation ol the screen as required tor the opening and closing thereon at the same time exerting siiliicient tension on the said screen to counteract the tendency ot wind pressure to bulge or warp the same in an objectionable manner or to set up vibrations or flapping such as is 'frequently observed in screens as commonly employed in verandas, porches, sim rooms and so toi-th; and the general arrangement suggested forms a much more workmanlilie adaptation of screens to buildings than is usual, greatly adding to the comfort of dwellers, being readily adjustable to meet diil'erent weather conditions, and etliciently Afulfilling the purposes tor which it is intended.

rlhis invention may be developed within the scope ol the Afollowing claims without departing from the essential l'eatures ol the said invention, and it is desired that the specification and drawing be read as merely illustrative and not in a limiting sense, except as necessitated by the prior art.

That I claim is l. Means tor the screening ot an opening, comprising slotted tubular posts at opposite sides ol said opening, an extensible screen wider than and adjustably mounted at one end of said opening, the margins ol" said screen being adapted to traverse the slots ot' said posts in the adjustment ol said screen, and resiliently yieldable means exerting tension transversely ot said screen.

Q. A device according' to claim 1, wherein the last mentioned means are carried by one ot the said posts.

Means for the screening of an opening comprising slotted tubular posts at opposite sides or said opening, rails within the slots olf said posts, an extensible screen, the inargiiis oi which are adapted lo traverse the slots ol said posts, means on the margins oli said screen slidably engaging and guided by said rails, said rails being movable l'or the purpose of exerting transverse tension on said screen, and resilient means eli'ccliug such movement ot said rails.

el. illeans 'l'or the screening ol an ipening, comprising slotted tubular posts at opposite sides oli said opening, railsl within the slots ot said posts, an extensible screen the niargins ol which are adapted lo traverse the slots of said posts, means on said margins slidably engaging and guided by said rails, means movably supporting the rails ol' one ot said posts therewithin, and resilient means exerting a pull on said supporting means which is transmitted to said sci-ecn and exerts transverse tension thereon.

5. Means tor the screening olE an opening according to claim il, and l'rieiiona means damping the movement ol said movable rails.

6. Means lor the screening ol an opening according to claim 3, and means adjuslably limiting the opposite movement ol' said rails.
