' The roller screen and attachment for windows,

according to this invention, comprises a housing .5 ill for attachment upon a window sill ll of a window l2. The window I2 is of conventional construction having window sashes I2 and 82 slidably supported in a window frame in the customary manner. The housing I0 is constructed 10 from sheet metal or other material and is fixedly attached uponthe window sill H by means of lugs it. A cover it! is provided for closing the open top of the housing i0.

A- spring roller it is mounted within the hous- :1 ing ill for rolling a screen upon itself. The roller it is formed at one of its ends with a peg I5 rotatively supported in the said end and extending from the end of a circular housing l6 mounted overthe said end. The peg I5 is formed at its 2 outer end with a square portion l5 which engages a complementary square opening formed in a bracket I! attached to one end wall of the housing Ill, The cooperation between the square end I! and the square opening formed in the brackets ll limits the peg against rotating. A means isprovided for causing the roller I4 to always return to its normal position after having been turned out of said normal position.

The returning means comprises a spring I8 coaxially engaged upon the peg l5 and having one of its ends engaging an opening 20 formed in the e of the roller II and the other of its ends engaging an opening 2| formed in the peg it. This spring I8 is confined within the tubular .3 housing It and is adapted to be tightened upon the peg I! when the roller is rotated in one di-v rection tor returning the roller ll to its normal position when the said roller is released.

A screen 22 has one of its ends securely at- #9 tached to the roller M. The screen 22 is of a width to extend entirely across the .opening in the window frame when the sash l2 is moved upwards. Binding strips 23 are mounted along the edges of screen 22 and. have their free ends extending past the free end of the screen 22.. The strips. 23 are securely attached to the screen 22 by means of rivets 24 which extend through portions of the strips 22 and the screen 22. The strips" are constructed from leather or similar material and are of channel shape and have the edges of the screen 22 engaged between the adjav cent arms thereof.

A member an is securely attached to the free ends of the strips 22. This member 25 comprises a piece of channel shaped metal having the free ends of the strips 23 engaged between the arms thereof and securely attached thereto by means of rivets 26. A means is provided for attaching the member 25 to the window sash i2 and comprises bolts 2-! engaging through the member 25 and threadedly engageable with nuts 28 securely attached to the bottom edge of the window sash i2". When this member 25 is securely attached to the window sash l2 and the window-sash is raised as shown in Fig. 1, the screen 22 will be extended from the housing i against the action of the spring I9. I

A roller 29 for an auxiliary section of screen is rotatively adiustably mounted between the binding strips and the top edge of the screen portion 22. The strips 23 in the vicinity of the top edgeof the screen 22 are formed with enlarged portions 23 into which the ends of the roller 29 engage. These enlarged portions 23 are clearly shown in Fig. 2, 3, 6 and '7. The means for rotatively adjustably supporting the roller 29 comprises a headed pin 30 engaging through an opening 3| formed on one of the strips 23 and engaging into one end of the roller 29. At the other end the roller 29 is formed with a square peg 32 which extends through a square opening 33 formed in the other strip 23, and the portion of the square peg 32 which extends beyond the outer edge of the strip 23 is formed with an opening. A cotter pin 34 is adapted to be passed for purposes of rotating the roller 29.

-means comprises elongated slots 35 formed in the through the opening, and have its free ends bent apart for preventing accidental disengagement oi the cotter pin and for holding the square peg in position within the opening. i

. A means is provided for permitting the square peg to be easily disengaged from the square openingwhen the cotter pin 34 is removed therefrom This enlarged portion 23 of the strip 23 through which the square peg 32 extends so that the portion between these slots may be bent out of the plane or the remaining portion or the strip 23 to disengage the square opening from the square peg. In their separated positions it is possible for the roller 29 to be manually rotated.

An auxiliary section of screen 36 has one of its ends wound upon the rollerand extendable upwards from the free edge of the screen 22 to the member .25. This auxiliary screen 39 is also the same width as the width of the opening in the 'windowframe and has its edges slidably engaging the strips 23.

A Lresilient means is connected with the top edge of the auxiliary screen 36 and is connected with the member 25 for holding this auxiliary screen in its extendedpositions. This latter means comprises tubular members 31 having their upper ends closed and their bottom ends.

. aligned with openings 33 formed in the top face opening between theifree edge of the screen 22 and the bottom edge of the member 25. When desired, the free edge of the auxiliary screen 33 may be adjusted to various positions along the opening between the screen 22 and the meni-= ber 25 for providing a small space between the v the position illustrated by the dot and. dash linesJ25 in Fig.' 2 to enclose the screen 22 and the auxiliary screen 36 within the housing Ill. The cover I0 is formed with an opening l3 of a sufliclent width to permit the enlarged portions 23 to pass therethrough so as to be wound upon the roller M.

The operation of this device is as follows:

The housing I 0 is secured upon the window sill l i and the member 25 is secured to the bottom edge of the bottom sash l2 by engaging the bolts 21 therethrough and threadedly engaging them on the nuts 28 i'astened to the bottom edge of the sash' l2. The screen 22 may now be extended from theopening I'll formed on the cover Hi by moving the sash i2 upwards. This causes the screen 22 and the strips 23 to be unwound from the roller l4 against the action of the spring l8. When the desired position for the sash l2 had been reached the open portion extending between the top edge of the screen 22 and the bottom of the member 25 may be closed if desired by extending the auxiliary screen 36.

To extend the auxiliary screen 36 one must remove the cotter pin 34 from the opening formed in the extended end of the square peg 32. Then ones finger nails are engaged into the slots 35 and that portion of the strip 23 been closed the square peg is again engaged into the square opening and the cotter pin 32 applied thereto for holding these parts in their interengaged relationship. The-cooperation between the 'squarepeg and the square opening'prevents the roller 29 from being rotated by the springs 39 According to the modification shown in Figs. 9

and 10, the construction of the roll screen is simflar of that previously described except that the construction is shown applied to the inside of a twin window l2. A hollow casing I0 is mounted upon the window sill II and has two separate and distinct roll screens mounted therein each of which is individually attached to the bottom sash of each window of the twin window I 2'. Likewise there, is a hollow casing H1" attached to the top of the window'frame. This housing I 0" is also provided with two-separate and distinct roll screen constructions. each of which is attached to the top edge of one of the top sashesof said twin window. In other respectsthis form is identical to the prior form and the same partsmay be recognized by the same reference numerals. A

According to the modification shown in Fig. 11, the construction'of the. roll 'screen is 'similarto that previously described except the hollow casing 10" is mounted below the window sill li'. A similar screen casing lll is mounted above the top of the window frame and is provided with suitable, doors it". The screens 22' are mounted to the window sashes I2 and l2 in any suitable manner.

It is to be understood that this-screen device may be used for any suitable purpose and at any desired location.
