INVENTOR ATTORNEY Lilly-WMM BY m may LEWIsR. BORLAND, on .Frenzen ivrrrnvnso'rn.L j

To all whom t may 'cncemk v ,-Be' it known that'I, LEwis'R.' BORLAND, a citizen', of the United States, residing 'at Frazee, 'in the county of Becker'and State of `l\flinnesota,'liave vinventednew and useful n'ip'rovements p Screens, of 'which the following is a specification; v ,c

This' invention comprehends the provision "of a household screen v,which may be utilized for various purposes, and embodies a plurality of "collapsible frame sections which when broughtv together in a collapsed condition produces a comparatively small' `compact article", with the screen fabric interposed bef tween thecomponent parts ofthe frame to' be "protected by the latter."

'The nature and advantages of the invention will be better understoodwhen the followingdetail description is read in connection with the accompanying drawings, the invention residingin the construction, combination and "arrangement of parts as claimed.

the drawings forming part of this speciiication'like numerals of reference indicate similar parts '1n the several' views and" wherein Figure "l 'is a rear'elevation of the screenK4 -eXtended."" i

Irrespective ofv the' number Yof uprights employed in aV single screen, every' two adjacent uprights are connected'by diagonallydisposed bars 11 whichare'p'ivotally connected together at their p`0int`of 'intersection as at 12, the oppositeextremitijes of the'respective bars being forked orbifi'ir-I cated, while the `prongs 1Q of said extremi-` tiesarepivotally associated with the lugs 13` pro] ectlng from diametrically opposite points" of the collars 14. The collars 14 with whichv the upper extremities ofthe barsll are associated, are mounted for sliding adjustm'entson vthe"uprights as well as rotation thereon7 to permitthe 'frame to be folded'or` collapsed viny the manner shown. The uprights 10 adjacent their Ilower `extremities are provided-with reduced portions l5 about which the sleeves 14 connected with'the lower i extremitiesV Aof the bars 11 are arranged. These latter mentioned sleeves while permitted rotation 4with respect to the uprights,` are prevented from sliding adj ustnientuponthe uprightsas in the case with the othersleeves adjacent the upper endsof-the latter. When` the vuprights 4are spaced, and the screen in a setup position-for use, the structure is given -a desired rigidity, 'through the instrumentality of the braces 17, which are interposedbetween= the bars'llrandfconnected' theretdas clearly shown in Fig. l, but each of which braces are hinged at the center to permit the frame to be folded or collapsed in the manner to be presently described.

In practice, the screen can be given different formations when its use is desired, by arranging the uprights 10 in different positions with respect to each other, as will be readily understood. However, when it is desired to fold or collapse the screen the end uprights are swung in a direction about the center upright as a pivot, to a position whereby the screen fabric will be arranged on the inside of the uprights. This is the folded position of the screen prior to collapsing the frame, and is clearly illustrated in Fig. 2. used in connection with a single screen, the proper upright is selected for the pivot, and the remaining uprights swung in the direction so that the screen fabric will be disposed on the inside of the uprights. Reference' to Fgs antivir. win-be 'noted' that any numberof uprights' 10` may be' employed" in the prr'iduction ofthe vscreen tdvary the" formation of the latteifwlien in set up 'posi- When more than three uprights are ring now to Fig. 4 of the drawings, it will be noted that subsequent to the positioning of the uprights in the manner vabovel stated, the braces 17 are broken at their center, to permit the frame to be collapsed. VThe end uprights being disposed in juxtaposition as shown in Fig. 2, it is only necessary to move the remaining upright or uprights in the direction of the end upright-s, to provide a comparatively small compact article, during which operation the screen fabric B is gathered or positioned between the respective uprights of the frame and thus protected from injury during transportation from one place to the other. As the uprights are brought together during the collapsing of the frame A, the collars 14 which are slid ably mounted, move in the direction of the upper extremities of the uprights, while all of lthe collars being rotatably mounted on the uprights permit the latter to be swung into any desired position about one of the uprights as a pivot, either to vary the form of the screen when in use or to facilitate the folding or collapsing of the screen when its use is vnot desired.

While I have shown and described what I consider the preferred embodiment of the invention, I desire to have it understood that I do not limit myself to this precise construction and arrangement, and that such changes may be resorted to when desired as fall .within the scope of what is'claimed.

l/Vhat is claimed is:-

1. A collapsible household screen comprising a frame and a screen fabric secured thereto, said frame including a plurality of sections, each having spaced parallel uprights, diagonally disposed cross bars connecting each pair of uprights and pivoted at their points of intersection, the upper extremities of said cross bars embracing' said uprights, collars carried by said eXtremities and surrounding said uprights to permit relative rotation of the respective sections of the frame, and said sections to be swung in either direction to a position for use, said collars being also slidably associated withfsaid uprights to permit collapsing vof-said frame, and means for holding the uprights rigidly spaced in active positions.

2. A collapsible household screen comprising a frame and a screen fabric secured thereto, said frame including a plurality of sections each having spaced parallel uprights, diagonally disposed cross bars connecting each pair of uprights and pivoted at their point of intersection, said bars being connected with said uprights to` permit the respective sections to be rotated in either direction to assume differentpositions relatively, and to further permit said uprights to be closely associated in juxtaposition with the screen fabric positioned between the uprights, a brace rod interposed between said diagonally disposed bars and connected thereto for holding the latter andsaid uprights rigid in active position, and said brace including hingedly connected sections.

a 3. A collapsible household screen comprising a frame including a plurality. of parallel uprights, a pair of spaced 'collars rotatably mounted on each upright, the uppermost collars being also slidably mounted,`

diagonally disposed cross bars connecting each pair of uprights and pivoted at their.

point of intersection, the said bars having bifurcated extremities pivotally connected with said collars, and means for holdingsaid uprights rigidly spaced in set-up position.

In testimony whereof I ailix my signature.
