PATENT OFFICE ConPonoN, OE POETLAND, MAINE, AssIGNoR To THE E. T. EURROWES` COMPANY, or PORTLAND,A MATNE, A CORPORATION rOE MAINE ADJUSTABLE WINDowscEEEN y Application mea August 7, 1929.l 'serial No'. 384,045.

".lhis invention'relatesto adjustable win-V dow screens androll `boxes therefor, and belongs to that class or type of roll holders for screens of wire net or the like that are 'carried upon a roll of the so-called. Hartshorn' construction, wherein the screen is rolledgup by the action of acoil spring in z the-roll or roller, andis drawnout by hand V'and automatically releasably latched to expose Vdifferent lengths of the. screen. y VOne of the objects of this invention is the -f provision of a kbox'or roll holder having 1 special Vconstruction and arrangement of parts, for housing the screenwhen rolled up 15.011 the roller, and permitting the roll to be i' readily takenV out and replaced when desired. It is also an object of this invention to so locate the box and the special features thereof that the 'screen may be drawn out to pro- ,20 tect the entire windowopening, so that no kOpenspaces vare left at the sides or bottom VKof thefwindow frame for the entrance lof insects.

' A further object. ofthis invention .is to provide adequate upright devices'at the sides of thewindow to suitably guide the. screen as 'it' is raisedy and lowered, and which valso act toA eliminate any side spaces asstated which would be otherwise open.

Another object ofthis invention is to afkford full protection to the material of the screen when not in use, and to that end the box'or housing hereinafterdescribed is made f of stout sheet` metal which isunalfected by moisture-or weather conditions, and. when ythe screen has been vrolled up into the box vit is effectively stored for any desired time,

and does not in any manner interfere with the area throughwhichlight is intended to Other objects'- andY featuresof structure willappear from 'the subjoined'description,

and from the drawings Vaccompanyingand,

forming a part of this application.V

Of the drawings, Figure l represents the inside of a window frame showing the sill and trim thereof and to which this invention has been applied.

Figure 3 is a tripartite illustration in perinvention appliedthereto and also inV section.,

and exhibiting also the; removable. front board which/may be employed to hide the` box from thek sight of an observer in the room. Figure `5 isa horizontal section of'a part of a Vwindow frame showing the screen guide, the vertical wooden bar tol which the guide is secured, and the molding attached tothe window .framein front of the guide to hide the same. f f f Figure 6 is a perspective view of the; upper portion of the guide supporting bar with the screenguidecarried thereby.

Figure is a horizontal section throughthe end of the front or-apron board, showing the devices `for removably keeping the board in place on' the window frame, Vand setting forth also on-e end of the roller box or housingn itsposition `with respect to the front board.

.Throughout the .drawings and description the same number is usedto refer to the same part, and the termsemployed'to designate the various parts will be understood to be only for the purposes of this explanation.

Thewindow'frame 1 has the usual .trim 2 and sill 3 all of customary pattern rand ar- Y rangement. Y n s At the top ofthe window is located and suitably fixed in position the oblong, andi as a rule, rectangularroll box or housing referred toasV a whole bynumeral 4:. Theends 5 and y6 of the box as shown in Figure 3 maybe permanently attached in'place by spot welding, soldering lorwotherwise. It will be noted y rthat the-end 5 is made with a right `angle flange 7 by which it is j oined to the box walls, and one portionof the flange isprovided with the screw holes 8. It will further be observed that a slot 9 Aextends fromtheV middle portion of the lend 5 and opens through the portion of f LA on the roller by the reaction of the roller sprin g not shown andin the well known mode of operation of such rollers for ordinary window shades. This invention is not, however, limited tothe use of a spring operated roller, as other means could readily be devised to perform. the 11e-rolling function. Variations may be made, it is believed, in the precise shapes or sizes of the combined elements of this invention without departing from the spirit or purview thereof. y

Having now described this invention and explained the mode of its operation, I claim :e-

l. vIn a roll box for 'adjustable window screens, the combination with a roller having at one end an axially projecting cylindrical lterminal and at the other end a flattened projecting terminal, of a box having a removable wall, said box having one endprovided with .an orifice affording a bearing for one of' said projecting terminals of the roller, the other end of the box comprising two members, one ofsaid members being constructed with a slot extending to the edge of the member and the other member having a central opening formed to receive the other terminal of the roller, and means for securing said wall and the two end members to the box. 1

2. In a` roll box for adjustable window screens, the combination with` a roller having at one end an axially projecting cylindrical journal and at the other end a flattened projecting terminal, of a. box having a removable` wall, saidbox having one endfprovided with an orifice affording means for holding said Hattened terminal against rotation, the other end of the box comprising two members the outermost of said members having a slot from its middle portion and opening to the edge of said member, and the innermost member having a bearing for the journal of the roller, and means for securingsaid walland said two end members to the box.
