1 Claim.
This invention relates to window screens of the roller type for application to windows in such manner as to automatically cover the variable open space produced as the window sash is raised and lowered.
One object of the present invention is to provide a screen of the character described that maybe readily adjusted to t windows of `various widths. I
Other more specific objects and advantages will appear, expressed or implied, from the following description of an illustrative embodimen of the present invention.
In the accompanying drawings:
Figure 1 is a view infront elevation of a screen constructed in accordance with this invention and shown applied to a standard window.
Fig. 2 is a vertical sectional view thereof.
Fig. 3 is rear view looking into the screen housing.
Fig. 4 is a vertical sectional view of the screen and housing on a larger scale.
Fig. 5 is a longitudinal sectional View of one iof the rollers shown in Fig. 4.
Fig. 6 is an enlarged sectional view 0f an edge of the screen.
-The window screen selected for illustrationcomprises two overlapping sections Ill and II of screen material wound `-upon separate rollers I2 and I3 with their free ends removably attached by suitable means, such as screws I4, to the bottom of a lower window sash I5.
The rollers I2 and I3 are arranged one over the other in spaced, parallel, but overlapping relation within a suitable telescopic housing I6 removably attached to the window sill I1 Iby,
screws I8 or the like.
The housing shown comprises an outer section I9 of angular form having an end wall 26, and an inner section 2| of similar yform slidably engaged within the outer section and having an end wall 22. Inturned flanges 23 on the outer housing section provide suitable guides for the inner section.
Both rollers I2 and I3 are hollow and spring urged in a direction to maintain the screen sections taut. As shown in Fig. 5, the upper roller I2 is supported at one end by a pin 24- carried thereby and journalled in a suitable hollow boss 25 welded or otherwise fixed to the end Wall 20 of `housing section I9. The other end of the roller I2 is rotatably supported on a pair of disks 26 and 2'I loosely tted therein and fixed to a rectangular bar 28 non-rotatably seated in an ear 29 carried by a suitable bracket plate 30. The
bracket plate 3|) is removably fastened by engagement of the ends thereof Ibeneath the inturned edge flanges 23 Tof the outer housing section I9. A coiled spring 3| engaged with the disk 21 and roller I2 urges the roller to rotate in the manner above described. The roller I2 is thus supported by and within the outer housing section I9 Wholly independently of the inner section 2|.
In a similar manner the other lower roller I3 is supported by and within the inner housing section 2| independently of the outer section I9. That is to say, the lower roller I3 is supported at one end by a pin 3 2 journalled in an ear 33 carried by the inner end ofthe housing section 2| and at the other end by a rectangular bar nonrotatably seated in a hollow boss 35 carried by the end wall 22 of the inner housing member.
By winding the screen sections Ill and II on separate rollers I2 and I3 arranged one above the other in the manner shown and described, it is possible to maintain a tight, firm, face-toface contact Ibetween the overlapping portions of the screen sections as the window sash is raised and lowered. By this arrangement it is possible to eliminate the gap-producing lbulges that would inevitably result if attempt were made to wind both screen sections in overlap-ping relation on a single roller. Als-o, by virtue of this arrangement and the fact that the rollers I2 and I3 are separately carried in their respective housing sections, it is a simple matter to adjust the housing sections telescopically to t windows of various widths, the rollers and screen sections carried thereby being free to automatically adjust themselves in accordance with any adjustment of the housing sections.
Various changes may be made in the embodiment of the invention hereinabove specilically described without departing from or sacrificing the advantages of the invention as defined in the appended claim.
I claim:
A window screen comprising a longitudinally adjustable housing having a pair of inner and outer telescopic sections lengthwise adjustable relative to each other, a pair of longitudinally overlapping rollers extending lengthwise of and within said housing, a rpair of overlapping flexible screen sections respectively wound on said rollers, means at the opposite ends of said inner housing section for supporting one of said rollers, means at the outer end of said outer housing section for supporting one end of the other of said rollers, a plate disposed within said inner 3 4 housing section and secured at its opposite extremities to said outer housing section, and UNITED STATES PATENTS means on said plate for supporting the opposite Number Name Date end of said last mentioned roller. 998,102 Lading July 18, 1911 WALTER L.
