Rename SCREEN Application fired May'11','192s. Serial 1161271644 This' invention relat'es'to a screen of the type which is mounted: upon afroller. andwhich is movablelongitudinally so as to cover an 'openingf'such as a window when 5' desired ,or to be movedto an ineffective position' .Wound 'upon" the roller. The edges of such screens J commonly are engagedf in grooves, and move longitudinally along said grooves when the screen is shifted from one 6 position toanother." Such screens-frequently become disengaged from their retaining grooves, as inadvertent pressure thereagainst-,- the force of the wind or'thelike,

and it is .extremely difficult to replace the 5 edges ofthe'screen in the grooves.

Thepurpose of the presentinvention is to provide simple and efiective' means .for'replacing the screen quickly and easily in its guiding. grooves' after it has become disen-" p) gage d therefrom.

. Another oh'ect of'the invention is to provide" means for so reposltioning the screen which 1 may" be attached easily to existing structures'without necessitatingextensive rebuilding'of them; i

Afnrtherobj ect ofithe invention is the'prm vision of guiding'means which will automaticallj replace the disengaged edges of a'soreen in their ret'aining*groovesf'when' the. screen 1s moved longitudinally pastrthe "gulding To these-and other ends the inventionresides in certain improvements and combinations of'parts, all as will 'be'hereinafter more fully described; the novel features being pointed outjinthe claims at the end oif'the specifications In the drawlngst Fig. 1 is an elevation of; a window and 4Q rolling :screen'i applied thereto, illustrating a preferred embodiment of the invention;

The vertical edges of screens suchas this are-ordinarilyretained in grooves extending along"thesides of the supp-ortingmeans or" window frame 24m] The side Walls ofthese'grooves- V w Fig. 8 is an elevation of a part'of a Window formed, for example, by clamping plates 25 movably mounted within channels, the walls of which are formed by plates 26, shown especially in Figs. 3, 4 and 5. Normally the edges of the screen 21 extend into the groove between the clamping plates 25 in the manner shown in Fig- 3, and sufiicient clearance is allowed between the plates and the screen so that the screen may slide longitudinally in this groove as it is rolled upon or unrolled from the roller 22.

hen the screen has been adjusted to its desired position, it may be clamped tightly in place by moving the clamping plates 25 inwardly or toward the left as viewed in Fig. 3, which will result in clamping the plates" tightly together and gripping the screen between them. This action takes place on ac-- count of the hollow bead27 formed on the outer edgeof each of the clamping plates, which bead comes in contact with therounded portion'28 at the edge of the channel plates 26, when the clamping plates move to the left,and acts as a cam to force each of the clamping plates toward the ,other. The mounting of the clamping plates within the channel plates, and theimoving'of the same to a predetermined position therein either inanually or by means not shown produces a grip ping action'on the screen caused by the cam action afforded by moving the elements 27 on the inclined portions of the elements 28.

#Mounted oneach of theclampin'g plates I which form the side walls of the screen recelvlng groove, 1S aguiding member which extends outwardly in a general direction toward the central portion of the'screen. This guiding member may consist of a loop-like element having its ends 30 fixed in the hollow bead 27 of the clamping plates and its mid portion 31 extending outwardly, as shown in Fig. 6, and spaced from the edges of the screen receiv ng groove. The guiding members are arranged near the top of the grooves .21 short distance'below the roller, as shown quently been necessary heretofore. Itsometimes happens that a sudden gust of .wind will blow the edges of the screen out of its grooves, before the screenhas been clamped tightly between the clamping platesv 25.:1 Such a screen disengaged from the. grooves is shown in Figs. 2, 4 and 5. It will be noted that the guiding members 81 extend out;

sufiicien'tly far-from the grooves so that the edges of the screen are retained between them at all times, and there is very little likelihood of the screen pulling out from between these guiding members, especially since these members are placed comparatively close to the top of thewindow opening.- ne edge of the screen at the elevation of the uiding members will then appear as in *ig. 4, while at an elevation slightly below the guiding members the edge ofthe screen will be in the relation to the groove shown in Fig. 5.

Now if the screen be raised so that it is rolled up on itsroller- 22, each portion of the edge of the screen, as it reaches a position between the guiding members 31, will be guided or forcedinto the plane of the grooves,

and will thus be free to spring back or become seated inits normal position in'the grooves; In other :words, all that is necessaryto replace a disengaged screen is to raise it sothat the disengaged edges thereof pass the v guiding members, and the screen will be replaced. automatically. The screen may then be lowered again if desired andit would be'found to be properly seated in its retaining grooves. It is, therefore, but the work: of an instant to replace a screen equipped with this device, whereas heretofore many hours of labor have oftenbeennecessary to accomplish the replacement.

In. Figs. 8 and 9. there has been illustrated a modifiedform of the invention for use particularlywith screens whose edges are re tained in grooves 35 formed between a pair. of vertical supporting or frame members 36 at the sides of a window or other opening.

Such members 36 are frequently. of wood,

and in these cases the guiding membersfor' replacing thescreen when it has become, disengaged may be formed easily and'economically'by driving staples 37 into the members 36, as illustrated clearly in Figs. .8 and '9. The staples 37' may then bebent slightly out wardly away from each other as shown in Fig. 9. .The action of these guiding members 37 in replacing a screen is substantially the same as the. actiong'of the members '31 heretofore mentioned, and it is 'thoughtthat further description of thisform of the inventlon is unnecessary.

' In Figs. 10 and 11, there is shown still an.

. other modification of theinvention, in which the guiding member maybe formed integrally on the clamping plate instead of being attached thereto asin'the construction first shown. Figure 10. is afragmentary'elevation of a clamping plate 40, the edge of which has an extension or lug 41 formed thereon, and y the head 42 on the clamping plate is-extended along the edge of this lug 41 as clearly shown. Fig. 11 is a cross section through a.

pair of clamping plates of the form shown integers as tlie 'lo'opslilre' guiding m e'mber's" 31 in "the fdrih tf hhhtitin first described. v 1

Each {of the 'three 'gform s' "of 'the invention' heretotore"'c'lisclosed acts in substantially the sarife my; andea'ch comprises guiding mmbers extending outwardly hem the screenretaining' grooves so as to narrowtlie cleardistance between the two grooves Thus-each guiding member acts'in effect as anextensi'on" or'ithd-ival-lofthe groove, andexte nds in a general direction toward the other groove at the opposite side of-the window.

lVhile certain preferred embodiments of the invention have been disclosed, it is'to be understood that the inventive idea may be carried out in a number of ways. This application is therefore not to be limited to the precise details shown, but is intended to cover I all variations and modifications thereof falling within the spirit of the invention or the scope ofthe appended claims.
