ROLLING SCREEN.

Application filed March 1, 1907. Serial No. 359,988.
object to provide a comparatively simpleand inex ensive device of this character ca; pable of eing readily attached to a window frame and which will effectually prevent the entrance of mosquitoes or other insects to the interior of the room.
A further object of the invention is to provide means for raising and lowering the screen and means for guiding the latter when moved to operative and inoperative position.
A further object is to provide a tension dcvice adapted to bear against the screen as the latter is wound upon or unwound from the roller and thus assist in guiding the screen upon the roller as well as to hold the same under tension when in either raised or lowered position.
A still furthcr object of the invention is generally to improve this class of devices so as to increase their utility, durability and efficiency as well as to reduce the cost of manufactur Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the ap ended claims.
n the accompanying drawings forming a part of this specification: Figure 1 is a front elevation of a window provided with a roller screen constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view taken on the line 22 of Fig. 1. Fig. 3
is a transverse sectional view taken oil the line 3-3 of Fig. "2.
Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.
The improved screen is principally designed for attachment to windows and similar closures and by way of illustration is shown in position on a window frame of the ordinary construction in which 5 designates I the windo\\'-fra:ne,- 6 the casing and 7 the sill.
Secured in any suitable manner to the top of the window casing are spaced supporting brackets 7 in which is journaled a roller 8 carrying the screen 9.
One end of the roller 8 is preferably extended beyond the adjacent bracket and T0- vided with a squared extension 10 an to which is keyed or otherwise rigidly secured a s rocket heel 1] engaging the sprocket ciiain llwhichlatter also engages the smooth exterior surface of a pulley or roller 13 mounted on the casing 6 at a point adjacent the sill 7.
The roller 13 is mounted for rotation in a suitable supporting bracket 14. and is provided with spaced laterally extending flanges wheel and thereby prevent lateral displacement of the same.
The lower or free and of the screen is pro -vidcd with a. transverse reinforcing strip 17 the. opposite ends of which are preferably inclined or beveled as indicated at 18 for enthe strips 20. i
The strips 20 extend longitudinally of the casing on each side of the window and also extend transversely across the sill 7 so as to and thus prevent the entrance of mosquitoes when the screen is in lowered position. The stri s 20 also serve to guide the screen when the latter is moved to raised or lowered position.
Secured to the upper transverse rail 21 of the window frame is a bar 22 having a longitudinal recess 23 formed therein in which is slidably mounted a yieldable supporting strip 24 adapted to bear against thescrsen 9 and hold the same in position on the roller as the scileen is wound upon or unwound from said r0 er.
Interposed between the strip'24 and the bar 22 are a plurality of coiled springs 25 havtheir lower convolutions secured in any suitable manner to the adjacent wall of the r cess 23 and their reduced 'convolutions seated in a groove or channel '26 formed in the stri 25.
It W11 thus be seen thatthe; springs are free to expand and contract as the screen is 15 which serve to center the chain on thegagement with suitable guides 19 formed in hold the screen 9 against thewindow frame wound upon or unwound from the: roller mirably adapted fonthe attainment of the thereby not only serving to guide the screen on the roller but also serving to maintain the screen under tension.
The transverse reinforcing bar 17 is preferably provided with a depending finger piece 27 while the rollercarrymg screen is housed and protected by a suitable casing 28.
In order to raise or lower the screen it is merely necessary to exert a longitudinal pull on the sprocket chain 12 which will rotate the sprocket wheel 11 and through the medium of the roller raise or lower the screen according to the direction of the pull exerted on the chain.
The screen may also be moved to operative or lowered position by exerting a downward puli on the 'nger piece 27.
It will here be noted that the casing 28 'forms ahousing for both the roller and tension device while the brackets 7 constitute closures for the opposite ends of the casing and also form bearings for the screen carrying roller.
While the device is principally designed for use in dwelling houses, 'oflice buildings and the like it is obvious that the same may be used with equally goodresults on car windows to prevent the entrance of dust, cinders and other foreign matter-to the interior of the car.
' From the foregoing descri tion it will be seen that there is provide an extremes, simple, inexpensive and efficient device a ends in view.
Having thus described the invention what is claimed is:
The combination with a window frame, of
a bar extending transversely across the top of said frame and provided with a recess defining spaced longitudinal guide flanges, brackets secured to the window frame and form- .in Y closures for the o osite ends of the reis P5 cess, aroller journale in said brackets, a screen secured to the roller and forming a closure for the window, a longitudinal strip slidably mounted for horizontal movement between the flanges of the longitudinal bar and provided with an intermediate seating groove communicating with the recess in said bar, coiled springs seated in said groove and recess and bearing against the bar and strip, respectively, for yieldably supporting the latter in engagement with the screen at said roller, a casing secured to the brackets and top of the longitudinal bar, respectively, and forming a housing for the roller, and means for operating the roller thereby to move the same to operative and inoperative position.
In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
