Oct. 4, `1932. F. vucHETlcH WINDOW SCREEN Filed May 25, 1951 INVENTOR v fri/fk Var/zezz'c Patented Oct. 4, 1932 FRANK VUCHIETIGH,A OF DETROIT, MICHIGAN WINDOW SCREEN Application inea May 25,

The present invention pertains to a novel window screen, having particular reference to .that class of window screen which may be adjusted to t windows of various sizes.

The Vprimary object of the present inven- .tion is to devise a window screen and supporting mechanism that permits the same screen 'i to be used on different windows that vary both as to height and width, the screen being capable of rolling itself into an enclosing casing when such is desired so that access may be had through thewindow. The present screen includes la telescopical roller around which the screen is rolled by a coiled spring mechanism contained therein and an enclosing casing which is also telescopical. The screen proper is woven in a manner. so that it may be expanded or contracted and is secured ,at its sides adjacent `the ends of the telescopical rollers so that a screen is pro- Qvided that maybe varied in width. A screw -mechanism is provided within the rollers to f positively lengthen or shorten the same along with the telescopical enclosingv casing, the screw also serving to hold the screen in any position of adjustment.

With the above and other ends in view the invention consists in matter hereinafter set forth andmore particularly pointed out in 3@ Ythe appended claims, reference being had to the accompanying drawing, in which Figure 1 isa front elevation of the screen with the supporting mechanism therefor broken away and vin cross section; y

Fig. 2 isa transverse cross sectional view l.takenalong the line 2-2 of Fig. 1;

VFig. 3 is Va'transverse cross sectional view taken along the linel`3-3 of F ig. l, and

f Fig. 4 is an enlarged front elevation of al fragmentl of thescreen. Y a

Y Like characters of reference are employed throughout to designatefcorresponding parts. The numeral 1 indicates a bracket that is vsecured to a windowfframe or to the 'wall adjacent a window and secured thereto is a casing member 2 which issubstantially semicircular in cross vsection 'as Aillustrated in 'Fig 2.v A"At'the opposite end is secured a similar bracket 3A having asimilar casing member 4 of a size permittingit tojbe slipped 1931. serial No. 539,727.

'into the casing member 2. The-casing ymember 2 is bent over the edges 'of the casing member 4 as illustrated at 5 in a manner to prevent movement of the two casing members relative'to each other in any direction 55 except longitudinally and in this manner the two casing members are telescopically mounted one within the other.

An elongated screw 6 is rotatably mounted inthe bracket l as at 7, the outer end of the screw being provided with a :fiat portion 8 that extends outside the bracket 1 and this flat portion is engaged by a plate 9 that is secured to the outside face of the'bracketv 2 to prevent rotation of the screw. The plate 9 is preferably secured to the bracket by means of screws so that it may be readily removed to permit rotation of the screw when such is desired. f

Mounted on the screw 6 so that the latter 70 may freely rotate is a ring 10 and a tube 11 has its end secured on this ring by screws 12. Projecting into the opposite end of the tube 11 is a tube 13 having a ring 14 secured in its outer end. In the inner end of the tube 13 is mounted a bearing ring 15 that has a groove 16 formed therein which receives a ring 17 that is attached tothe tube 13 by screws 18 and in this manner the ring l5 is free to rotate relative to the tube 13. A hol- 8 low stem 19 has one end mounted in the ring 15 and its opposite end rotatably mounted in the ring 14 and the bracket 3, the outer eX- tremity of the hollow stem being formed with a fiat portion 20 that is engaged .by a 85 plate 21 to prevent its rotation, the plate 21 4being secured to the outer face of the bracket 3 preferably by screws so that it may be readily removed to permit rotation of the j. Stem. 19. '9

The hollow stem 19 receives the end of the screw 6 and is provided with a screwthreaded portion 2 2 that engages said screw so that rotation of the screw causes the parts to be telescoped in a manner to be presently 'de- 95 scribed. g

kThe ring 14 is secured in the end of the tube 13 by screws 23 and is formed with a lug 24 to which is attached one end of a coiled`r spring 25,'the oppositey end of the coiled l spring being attached to4 a lug 26 formed on 'l the ring 15. YThe spring serves tore-roll the f screen that is mounted upon the tub-es 1l and Y y13 ina manner to be described in a later part L of the description.

A wire mesh screen 27 is formed with vertical strands 27A around which are looped,

angularly extending strandsv 28 so that the screen may be contracted or expanded. This vin which thevstrands 28 are woven ypermits the strands 27 to be moved closer together if such should be desired. i f

v The screen is formed with acomparat-ively close-,mesh adjacent eachsideas at 29 and screws `30v are ypassed through thisportion of the screenv into thetubes l1 and 13ste secure 3 the screen thereto. It will be noted however,

Although a specific embodiment of the present invention has been illustrated and described it is to be understood that nvarious changes may beinade in the details of construction without departing from the spirit of the invention as set forthtin the appended claims, and such changes areconteniplated.
