In said drawing, l0 designates. a windowt ains or casing in position, the wall of a. buildin M- 2 denotes a housing or casing of metal or Other suitable material comprising end members or heads 13', and a substantially-.cylfindrical intermediate portion l4 secured at its; opposite ends to. heads 13. having. inwardlywextending peripheral flanges we The. housing i2. hasafiatarea wall 15. from whichv extends outwardly 2. horizontal flange i6 adapted: to. receive screwsor other fastening devices, for securing said, housin to the. upper member ll or the window casing' or frame.- it. The forward portion or the housing; i2. is substantially sfimiecirculan in crosssection, and, terminates; at its upper edge in a flat. horizontal. portion 1-8; which merges with th upper edge of the rear wall 1.5., The. lower edge oi: the housing. i2. rminates in relativelyenarrow flat portions, i9, He, or which the portion ass merges with the lower edge of the rear wall l5. The portion; 19% is provided with a longitudinal slot. 26. having turned up. rounded edges. 2.1.

Eachhead or end member [3 is provided upon its inner side with: a centrally disposed pyramidal bearing or boss. 22- having a square socket therein in which is secured by a screw 23' the end 2-4 of a shaft 25. The end 2 3 is. square incross section to. fit said socket. This shaft serves as a support for the screen reel, and at the same time serves as a tie-rod'tosecure the heads l3 and'inter-mediate portion Hi and associated parts in duly assembled relation.

Upon the shaft 25 is revolubly disposed a hollow roller or reel 26 having annular heads 21 atits opposite ends; and a revoluble head 21 secured within the roller inwardly of its ends by a drive pin 21*.

28 denotes a spring disposed within the roller '26 and surrounding the shaft 25, andhaving one end 29 fixed to said shaft, and its other end 30 fixed in an aperture provided in the inner side of the disk or head 21 whereby the tension of said spring may be varied, as required. Upon said roller 26 is secured the upper end of a screen 3! provided at its lower horizontal edge with a transverse bar 32 formed of a strip of sheet metal folded or doubled upon itself to form front and

rear members

33, 33 respectively, intermediate of which is disposed the lower horizontal edge of the screen 3!, and the

members

33, 33*, then secured together by spot welds 34 with the screen 3: therebetween. The opposite ends 35 of the bar 32 extends into, and are received by the vertical slots of the channel members 36 secured at the opposite vertical sides of the window casing or frame.

The channel members 36 are of rectangular form in cross-section, and provided at their forward sides with longitudinal flanges 33 having holes 33 therein to receive screws 36 whereby said channel members may be secured to the side members of the window casing or frame ID. The inner vertical edges of said channel members 36 form guides within which the projecting ends of the transverse bar 32, at the lower edge of the screen 3| are adapted to work, and at suitable intervals along the opposite vertical edges of the channel members 36 are registering substantially semi-circular recesses 42, to accommodate the bolts 38 for securing the screen 3| to adjusted positions. Preferably recesses 42 located at the lower ends of the channel members 36, to permit of the locking of the screen in fully lowered position, and about mid-way of the height of the window casing or frame, to permit of the securing of the screen 3| in half-way extended position will be sufiicient for all practical purposes.

The bar 32 is provided in its front and

rear members

33, 33 with registering pairs of semicircular horizontal portions 31 jointly forming tubular portions 31* which serve to stiffen or reinforce said bar. The upper of said tubular portions 31 forms at its opposite ends housings for slidable, spring-actuated bolts 38, having finger portions 39 working in bayonet slots 40. The ends of the bolts 38 are adapted to be projected by their actuating springs 4|, into engagement with the recesses 42, provided in the slotted edges of the channel members 36 to hold the screen to its adjusted withdrawn positions. The bolts 38 are held to their retracted positions by the engagement of the finger portions 39 thereof with the angular rear ends of the bayonet slots 40.

The screen 3! is provided at suitable intervals along its opposite vertical edges and within the channel members 36 with double-headed rivets 3!- which serve to retain the screen duly in position, and prevent the vertical edges from being withdrawn from said channel members 35 in the course of the movements of the screen, or when said screen is subjected to any undue strain or pressure at right angles to the normal thereof. 43 denotes a handle secured to the transverse bar 32 intermediate the tubular portions 31 to facilitate the raising and lowering of the screen 3|.

The operation of the device will be obvious from the foregoing description.

It is to be noted particularly that the screen embodying our invention may be readily applied to either the inside or outside of a window frame or casing without necessitating any structural alterations or modifications of the window frame or casing. Further, it is to be noted that the 4 housing within which the rolled screen is disposed, when not in use, together with the operating parts enclosed by said housing are all secured together in operative relation by the shaft 25 and the securing means therefor.
