.This invention relates to windowscree'ns and more particularly to the type adapted to-lfbe Wound. on a spring-roller.

The principal object of the present invention is to provide a rolling window screen which is adaptable to any type window, such as sash,

provide a rolling window screen which when unrolled is completely sealed and affords the utmost in protection against insects and similar pests, regardless of size.

Another object of the present invention is to provide a dust-proof compartment for receiving a rolling window screen and having means internal thereof for rendering a spring-roller operable.

Another object of the present invention is t provide a rolling window screen adapted to be unrolled upon the raising of a lower sash to therebyscreen the opening thus afforded, and .to be rolled when said sash is lowered; or to be unrolled upon the lowering of an upper sash to thereby screen the opening thus afforded, and to be rolled when said sash is raised.

Another object of the present invention is to provide means by which a rolling window screen maybe locked to and easily detached from a window sash or sill when so desired.

Another object of the present invention is to provide means for the uniform lifting and lowering of a rolling window screen to thereby assure an ease of operation and the proper rolling there- Another object of the present invention is-to provide bracketing means whereby the screen enclosing compartment may be easily affixed to a window frame.

-- For further comprehension of the invention,

and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claim in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a ma- Fig. 1 is a front elevational view illustrating the present device screening the entire opening of a window.

1 Claim. I (01. 160-23) screen enclosing compartment and the brackets for the mounting thereof.

Fig. 3 is a fragmentary isometricview of-one end of the compartment and the screen roller.

Fig. 4 is afragmentary isometric view of the other end of the compartment and screenroller.

Fig. 5 is a fragmentary view illustrating the screen locking and screen sealing means.

Fig. 6 is an isometric view illustrating the present device as adapted to screen the opening effected by the raising of a lower window sash.

Fig. 7 is an isometric view showing the present device adapted to screen the opening effected by the lowering of an upper window sash.

In Fig. 1 the frame l0, comprising a roof ll, left and right side upright members l2 and I3, respectively, and a sill l4, represents any window frame, be it that of a sash, casement, or any other type. The compartment l5 fits between the side members l2 and i3 and is bracketed thereto by left and right-hand brackets l6 and [1, respectively, which are seen better in Fig. 2. Said brackets l6 and H are provided with bent-over rear and bottom portions l8 and I9, respectively, and when properly mounted to their respective side members l2 and I3 are adapted to receive therebetween the compartment I5, the rear bent-over portions l8 limiting the rearward extent of movement of the compartment l5 and the said bottom bent-over portions l9 providing support to said compartment. As also seen in both Figs. 1 and 2, an

angle strip 20 is centrally disposed on and fixedly secured, as by spot welding or similar means, to the front of the compartment I 5, and is provided with a hole 2! for receiving a screw or nailin order that said compartment may be secured in a proper operating position between the said brackets l6 and I1.

Fig. 1 also illustrates the manner in which the rolled screen 25, which will be described in detail hereinaftenis completely hidden in the said compartmentsflli'i. band the sealing channels 26 and the locking meansZI, both of which will also be described hereinafter.

The roller 24 having the screening material 25 rolled thereon and seen in Figs. 3 and 4 is similar to the well-known spring-rollers used in window shades, and it will be suflicient'herein merely to indicate that one end is provided with a stationary pivot pin 2t while the spring mechanism end is provided-with a revolvable fiat pin 29.

Fig. 2 is an isometric view illustrating the 58 welding or similar means, is a pivot bracket 30 removed from the slots 32 and 33 and the pivot pin 28 is first positioned in the bracket. 30,.then the flat pin 28 is inserted in its related bracket 36.

Subsequently, the bracket slide 35 is inserted.

in the slots 32 and 33, and therestraining action 2, 3 and 4,.a .cut-outslot 31' in the underside of the compartment l5 permits. the passage therethrough of the screening material 25.

Now, in' order; that the screening might be sealed to prevent the passageof 'insects'orbther like pests between the sides thereof and the upright side members !2 and E3 of the window frame 59, and in order that said screen may be raised and'lowered easily and guided to roll properly, sealing channels 26 are provided and are screwed or nailed to said frame side members ['2 and i3. Said sealing channels 26 may be of any required length and of any suitable'material; and as best seen in Fig. 5 are preferably formed of flat sheet metal strips folded lengthwise upon themselves and each having its sides 38'and139 bent over in the same direction to thus form a channel 40. The screening 25'has attached at the freeend thereofa rigid cross member 2!; the ends of which and the sides of thescreening being adapted to fit slidably in the aforementioned channels 43 of' the left and right-hand sealing channels 26.

As also well seen in Figs; 1 and 5 each of the hereinab'ove mentioned'locking means 2 7 comprises an angle member 43-; the'uprig-htleg thereof being secured as at 44 to thesaid screen cross member 4'! and" having provided in'its horizontal leg a rectangular aperture 45; and a turn bolt 4'6 adapted to 'pass'through the'said aperture-45 when aligned therewith and not to be passable therethrough when turned'through an angle or: Slide.- grees. In both. Figs; l and-'5 the turn" bolts. 45 are'mount'ed on thawin'dow sill l4 and' the screen 25 is'lockablethereto. when rolled downand the said turn? bolts are passed through. theis'a'id aper tures45 and turned QOdegrees. Whemitiis' desired that: the screens-be opened the turn. bolts 43' are aligned with the apertures. 4'5 and with the assistance of the spring-roller 24 the screen is rolled up;

The just described arrangement providesxfor the: screening of' an entire window. However, as shown: in Fig; 6', the present invention is. also ap plicable. to: the-screening: only ot the opening effected by the raising. of alower Sasha-41w and may be-arranged to cooperate with said lower sash and be unrolled by the. same action with which the sash is raised. This modification provides-for the compartment IE-being mounted betweenthe lower ends of the side members I2- and I3 of the frame. In inthe brackets 16- and H and held in position. by the. angle strip. 20 secured to the. sill |4.- A150, the sealir'i'ezv channels 25 are ofi'on'ly half-lengths and the above described turn bolts 46 are mounted on the upper side of the lower cross member 48 of the said sash 41. With this arrangement it will be seen that, when the screen is locked to the sash 4! by means of the turn bolts 46 and the angles 43 and the window is closed the screen is completely rolled and hidden in the compartment l5, and when the sash is raised the screen is automatically unrolled accordingly. Thus, protection is provided at all times during the opening of the window.

. A similar arrangement is shown in Fig. 7 whereby the opening afforded by the lowering of the uppersash 50 is screened and the screen is automatically unrolled through the sash lowering operation. Here, as in Fig. 1, the compartment 15 mounted between the upright members I! and I3. of the frame In in brackets l6 and I1 and held in position by theangle strip 20 secured to the frame roofv ll- But, as in the last described modification, the sealing channels; 26. herein employed are half-lengths. Now, differing frornsaijd last described modification; the said turn bolts 46 are herein mounted on the underside of the upper cross member 5| of the said upper'sash 50. Therefore, when thelocking means 21 are effective, it will be seen that the lowering'ot the upper sash 50 effects the .unrolling of the screen 25' and affords the utmost protection against the entrance of insects, and that the raising of said upper sash 59 effects the rolling'of said screen 25.

It will be noted that in all of the above described arrangements, the compartment l5 when in its operativ position has its open side covered by either the frame roof H or window sill HI, thus having its inner elements protected at all times I from dust or other foreign damaging matter.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself tothe precise constructions herein disclosed and the right is reservedto all changesjand modifications'coming within the scope of the'invention as defined in the appendedfclaim.

Having thus described my" invention, what I claim as new, and desire tosecure'by United States Letters'Patent is Y 4 I In a rolling screen having a spring-roller with screening material rolled thereon and" a pivot pin at one end of the roller and -a;fla't pi'n at the spring end of the roller, a compartmenthaving one side open, a pivot bracket secured at'one end of said compartment for-receiving the pivot pin, apair. of slide. receivingslotsat'the other end of said compartment, a bracket slidably fitted -in said slots, and a restraining" bracket securedv to said bracket and the: fiat pin' being insertable into said restraining bracket when said first bracketis removed from-said slots.
