WINDOW- SPECIFICATION forming part of Letters Patent No. 507,755, dated October 31, 1893.

Application tiled April 15, 1892.

To all whom it may con/cern.'

Y Be it known that I, CHARLES W. RoDEoKER, of Maryville, Nodaway county, Missouri, have invented certain new and useful Improvements in Window-Screens, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates first to screens for the 1o windows of dwellings, business-buildings, and various other similar structures, and secondly to the sashes of such windows, and the objects of my vinvention are, first, to produce window-screens which shall be simple, strong,

durable and inexpensive in construction, and entirely automatic in their operation, and which shall be capable of application to all types of windows, and which shall be automatically extended and concealed .in consezo quence of the raising and lowering of the window-sashes, and which, furthermore, shall in no way cause any disgurement or material alteration in the structural features of the window frames or sashes; secondly, to z5 produce attachments forwindow-sashes which shall prevent the entrance of insects, dust, or other objectionable matters into the apartments, and which shall be capable of application to all types of window-sashes,and which 3o shall, furthermore, be simple, strong, durable, and inexpensive in construction.

To the above purposes my invention consists in certain peculiar and novel features of construction and arrangement, as herein- 3 5 after described and claimed.

In order that my invention may befully understood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure 1 is an inner side elevation of awindow frame and its sashes with my improvements applied thereto. Fig. 2 is a transverse vertical section of the same, on the line 2--2 of Fig. 1. Fig. 3 is a horizontal section of the same, on the line 3-3 of Fig. 1. Fig.4is

a detached perspective 'view of one of the screen-winding-rollers, its supporting-brackets, and a portion of one of the screens. Fig.

5 is a longitudinal section of the same, on the 5o line 6-6 of' Fig. 4; the roller-actuating spring being shown as partly broken away.

In the said drawings, 1 designates the frame or casing of a window, said frame or casing SCREEN.

Serial No. 429,249. (No model.)

being shown as of the usual rectangular form, and 2 designates the lower and 3 the upper sash of the window; these parts being (excepting as hereinafter explained) of the usual or any preferred form and type of construction.

4 designates a spring-rotated roller which is mounted horizontally in the window-casing 1 just above the sill 5 thereof, and which is of hollow cylindrical form, and of such length as to extend from one groove to another in which the lower window-sash 2 works. At one end this roller carries a cap r6 vwhich is riveted or otherwise secured upon the end of the roller 4, and from the middle of which extends a stud 7 the outer end of `Vsaid stud being inserted intoa bearing-opening 8 which opening is formed in the lower part of a vertical bracket 9. This bracket 9 is secured upon the sill 5 at a point adjacent to the wall of one of the grooves in which the lower sash' 2 works. Longitudinally through this roller 4 extends a rod 10 which is of such length as to extendfrom near the cap 6 to and through the opposite end of the roller. The outer end 1l of this rod is iiattened as shown and projects through a disk 12 so as to rotate freely in said disk. From the inner side of this disk project inwardly two anges 13 which are inserted intol notches in the. corresponding end of the roller4, thus preventing the disk from turning independently'ofAv the roller. Two external shoulders 14 and'15 abut respectively against the inner and outer sides of the disk 12 and thus retain the rod in its proper position without interfering with the free rotation of the roller 4. The flattened outer end 11 of the rod 10 enters a recess 16 in a companion bracket 17, the said bracket being secured in vertical position upon the sill 5 adjacent to the opposite groove from that occupied by the standard 9.

In order to prevent all possibility of accidental detachment of the flattened end 11 of the rod 10' from its bearing in the recess 16, a pivoted stop 18 is preferably secured vupon the outer side of the bracket 17, and when in normal position, depends across the outer end of the recess, and also abuts against a stud 19 which also projects from the outer side of the bracket. `Thus the stop or guard 18 may be raised when the end 11 of the rod is being inserted into the recess, and then al- IOO lowed to drop so as to close the outer end of the recess and thus retain the end 11 within said recess, the end 11 ofthe rod being moved to the inner end of the recess of course, to allow the pivoted latch to clear or pass said end 11, in its descent. A coiled spring 20 surrounds the rod 10 and its inner end 21 is inserted into a transverse groove or notch which is formed in the inner end of the rod 10, while the outer end of said spring is suitably secured to the inner side of the disk 12. Thus when the roller 4 is rotated in one direction, the spring 20 is wound, and when the roller is released, the spring automatically unwinds and rotates the roller 4 in the reverse direction. A collar or cap 22 is riveted or otherwise similarly secured to the corresponding end of the roller 4, as shown.

23 designates the lower screen section, the lower margin of which is suitably secured longitudinally upon the roller 4, and which is of'a width corresponding to that of the lower sash 2. At its upper margin, this screen-section is provided with a bindin g-stri p 24 the ends of which are bent inward so as to enter recesses 25 which are formed in the lower corners of the inner sides of the sash 2; the arrangement being such that the ends of the binding-strip and the screen-margins shall t snugly between the inner side of the sash and the inner bead of the window frame or casing 1. Three, or any suitable or preferred number, of loops 2G of wire or other suitable material, are secured to the bindingstrip 24 and are engaged with a corresponding number of nails 27, or equivalent devices, which are driven into the lower rail of the sash 2. Asemi-cylindrical shield or guard 28 is secured to the sill 5 and extends upward and outward so as to conceal the lower roller 4 and its attachments; said shield being of sheet-metal, or other suitable material, and corresponding in length with the width of the lower sash 2.

From the above description, it will be seen that when the loops 26 are connected to the nails 27, the lower screen-section 23 will be unwound from the roller 4, as the lower sash 2 is raised; this unwinding` of said screensection rotating the roller 4 so as to wind the spring 20. Then the lower sash 2 is lowered, the spring 20 will unwind and consequently the lower screeirsection 23 will be wound upon4 the roller 4.

In the upper part of the window-frame 1 just above the top-rail 29 thereof, is mounted horizontally a second roller 30 to which is attached the upper margin of the Lipper screensection 3l. This roller` 30 in all respects is the saine as the roller4 above described, and is also provided with caps 6 and 22, a rod lO, spring 20, and the other attachments the same as said roller4; the ends of the binding-strip 24 of this upper screen-section and the margins of said screen section, working between the inner bead of the upper sash 3 and said sash, as before described. Thus it will be seen that when the upper sash 3 is lowered, the upper screen-section 31 will be unwound from the roller 30; winding the spring 20 of said roller. When the upper sash 3 is raised, the spring 2O of the upper sash will be unwound and will so rotate the upper roller 30 as to wind the screen-section 31 thereon. Consequently, in both the upper and lower sashes, the opening which is formed by raising or lowering the sashes is covered by the screen-sections, and all insects are excluded from the apartment. The upper-*roller 30 is usuallyconcealed from view by the usual Window-curtain, but if desired, a shield or guard 28 (similar to the shield or guard 28, above described) may be used to conceal said upper roller, as indicated inl dotted lines in Fig. 2. In order to exclude dust, dirt, and insects from the room, a flexible strip 32, such as rubber or the like, may be secured to the ,upper bead 33 of the window-casing, and extend outward over the roller 30, so as to close the space between the roller 30 and the toprail of the Windowframe. In order to further prevent the entranceof dust, insects, dac., into the apartments, a strip 34, also of flexible material, is secured to the under snrface of the lower rail of the upper sash, and the inner margin of said strip abuts closely against the outer surface of the pane of glass in said sash, so as to rub closely upon said pane when the sashes are moved.

From the above description it will be seen that I have produced attachments which are simple, strong, durable and inexpensive in and secured thereto at one end,the combination of a cap 22 secured upon one end ot' the roller, and having an inwardly extending flange at its outer end and a disk l2 mounted loosely upon the said rod 10 and bearing against the inner side of the cap 22 and against the inwardly extending flange thereot', and having inwardly extending flanges'l adapted to engage recesses in the end of the Abody-portion 4, of the annular shoulders 14 and 15 bearing upon the inner and outer sides of the disk 12, to retain said rod in its proper position longitudinally, Substantially asset forth.

[n testimony whereof I aix my signature in the presence of two witnesses.
