SCREEN DEVICE FOR POCKET-WINDOWS.

Specification of Letters Patent.

Patented Mar. 12, 1918.

Application filed February 12, 1917. Serial No. 148,030.

To (tZZ whom it may concern Be it known that I, EDMUND H. LUNKEN, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Screen Devices for Pocket-VVindows, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawings, forming part of this specification.

idy invention relates to screens for pocket windows and has for its object the provision of a complete and fully adequate screening for sliding sash pocket windows having a wall pocket wherein the screens may be concealed.

One of the important advantages result-- ing from the use of pockets for windows is that window screens may be kept permaucutly in the windows and moved into the window pockets both to get them out of the way and for winter storage. The diiiiculties to be met with in providing for this advantage are several, however. In the first place, there has not been developed, to my knowledge, in the past, a proper method of installing sliding screens in such windows which permits of their easy setting up and removal. In the next place no proper weather seal has been provided between the window sash, the screens and the pocket walls, which is very important since without such devices there is always the possibility of draft getting into the room by circulating around in the pocket, past the screen opening and down along the sash of the window.

It is the object of this invention to provide against the above disadvantages, and the said objects now mentioned and other advantages to he noted are accomplished by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed, wherein particu larly the supporting rails for the screen channel guides are set in place in the windows after the pockets have been formed and are easily removable in one piece.

The pocket window has the upper and lower sliding sashes l and 2 respectively, which sashes slide on the stiles 3, which are provided with the parting rails 4:, inner guide rails 5, and outer guide rails 6. On

the outer guide rails 6 are to be mounted the screen channels and these outer guide rails (one on each stile oi the window), run with the stiles up into the pocket 7 formed in the walls 8 above the window opening. So far as the screen channel. members are concerned and the method of mounting the su iporting rails therefor, this function of the guide rails 6 in serving to guide the sashes not an absolute requisite, as the sash guide might be a separate member. Between the wall pocket and the interior of the building, there is the usual plastered wall 9. and the window frame is shown with the usual cap trim 10, base trim 11 and sill. 11. The plastered wall I prefer to construct with corrugated metal lath 9 which gives suflicient rigidity to the wall.

Secured to the top of each sash in the usual way, are the cords 12, which are led up to pulleys 13 in the top of the wall pock ets. The arrangement of pulleys and the method of counterbalancing the sash while permitting it to ride up to the top of the pocket is shown and described fully in my Patent No. 1,201,598, dated October 17, i916, to which patent reference is hereby made.

On the outer guide rail 6 for the sash, as

above stated, are mounted the channel guides for the two screens, there being a lower screen 17 and an upper screen 18. It is preferred to make up these guide channels in two different sections. Extending up from the base of the guide rail 6 on each side, is the lower channel section 16 (Fig. 3), which is of a si e toaccommodate only the lower screen member 17. This lower section extends up approximately to the center line of the window.

The top channel member 19 is set on. the guide rail 6 and mounted in the window frame with this guide rail as. will be noted.

t is of asize double that of the lower channel member, and thus is adapted to slidably receive both screen members. This channel mem er extends to meet the lower section and is cut away at 21 toleare space for a removable insert 22 which when screwed or otherwise secured against the guide rail completes the channel member 19 and forms of it a double width channel throughout. The removable piece 22 is in the form of an angle, and is adapted to extend beyond the lower edge of the top section and past the upper edge ofthe lower section. Set into the portion of the piece 22 which so extends, is a lug 23 which extends in such a way as to close off the one half of the channel flush with the top oi the lower channel member. This lug thus serves as a stop for the upper screen member, and may be of one piece with piece 22 or screwed down as shown.

The piece has its side wall bent outwardly at 24: so as to lap over the cut away edge of the side wall of the upper channel section, thereby forming a flush inner wall for the combined members against which the upper screen will not be likely to catch. There is su-ii'licient length to the portion 24 to allow for adjusting the position of the piece 22 and hence the lug 23 thereon, or else the lug may be positioned and the holes drilled for it after placing the piece As so constructed, the channels serve to slidably mount the screens throughout the length of the window opening and pocket, and as will be described tie removable piece 22 is all that need be taken off of the channel guides to permit both screens to be removed.

In mounting the channel members for the screens, they are first secured, all but the piece 22, to the rail 6. The rail 6 is then mounted in the window after the pocket has been completed, and as will be understood can be. readily dismounted and remounted again without difficulty. In forming the top of the pocket, the top board 6 of the pocket is cut away at 6* adjacent the side stiles of the frame, which extend up to this top board. This; cut 6 is suflicient to allow the rail 6 with the channel members thereon to be tipped up into the pocket, and pushed into the socket, the channelbeing cut away. Several screws beneath the pocket, or as far in the pocket as can be reached easily, serve to hold the rail in place. i

It will be understood that by removing the screws, the rail may be tipped and drawn out, and also that it is not absolutely essential that the rail be in one piece except so far as it extends into the pocket. The spirit of the invention is intended to cover the making of this railin several pieces, although it is not believed that this would be done in any practical structure.

The screens as shown are made up of moldings 2, across which are suitably stretched and held the screen wire. On the lower molding of the lower screen is mounted a depending angle piece 27, and at each corner of it are mounted the housings 27 for the sliding bolts or pins 28. Suitable sockets 29 for these pins are formed in the lower end of the side guide rails 6, and also at any other point along the rails, such as at 30 in the channel member just beneath the wall pocket opening, where it is desired to hold the screens. When the bolts are thrown in at 30, they will tend to close the space left in the channel by the upper screen, and for this reason should be made of suiiicient width to fulfil this function as much as possible. The angle piece rests on the sill and permits a finger hold on the lower screen molding. Also fingers 28 for the locking bolts project inwardly in the space beneath the lower molding of the screen, so as to be readily available passing through a slot in the angle plate. The piece 23 is beveled at to strike out the bolts 28 on raising the screen.

The lower screen member has at the out side of its upper molding a strip 31, which extends so as to contact with the upper side of the lower molding of the upper screen, and thereby form a complete insect proof joint. Then the lower screen is raised, this strip 31 strikes the upper molding of the upper screen and moves it upwardly also. When the lower screen is pulled down this strip strikes the lower melding of the upper screen. and pulls it down also, if it should happen to stick, in the pocket. 7

The upper screen has an angle piece 32,

set over its top molding, which piece 32 when added to the top molding makes it of the size of the double width channel, so that it will slide and be guided therein. This piece extends into the path of the top mold ing of the lower screen so that a wide contact is provided between the moldings of the upper and lower screens, since it will be re-' membered that the strip 31 on the lower screen also acted as a contact member. The size and position of the piece 32 can be, regn lated.

The top rail of the upper sash has set into it a weather strip This is preferably done by mounting the strip together with a molding 33 on the top of the sash rail. The weather strip extends rearwardly and the parts are proportioned so that the strip will contact with the lower molding or the lower screen when said lower screen is in the wall pocket, and also so that it will contact with the upper molding of the upper screen as filled out by the angle strip hitherto described when the upper screen is down.

Thus when the screens are stored for the winter, in the pocket, there will be a weather seal between them and the sash, and the weather seal will also be provided for when the screens are down and in use.

Set into the lower end of the outside trim of the window frame by means of a suitable molding strip 3%, is another weathe' strip 55 which is adapted to contact with the upper molding of the upper screen when down, and the angle piece depending from the lower screen is proportioned so that it will lie along the under side of the molding 34-. So no matter whether the screens are up or down, dust cannot circulate past the screens, up into the pocket and thence into the interior of a building through the pocket opening for the lower sash.

'lhe depending angle strip on the lower screen is wide enough to justclear the shannels and long enough to bringthe meeting rails of the screens adjacent the meeting rails of the sash. This is because the standard lower sash is usually longer than the upper, and to balance the screen structure it would otherwise be necessary to have screens of different size, which is avoided by the use 01 this depending strip. This positioning of the meeting rails of the screens is but one of the valuable results of the use of this depending strip since it also permits the upper molding of the upper screen to partially lie in the pocket, thereby forming a weather seal as above described. This angle strip and the other projecting strips are to be screwed into place on the screens so as to be removable for installation on replaced screens in case of repairs, so that the provision of screens for this structure becomes an easy matter since only standard screens of equal size need be obtained, and the molding attachments made by the installing contractor.

In putting up the screens. the rails are tipped into place and screwed down. with the channels on them as descril'ied. The lower screen is then slipped into place through the opening left for the piece 22. and dropped down in the channel member 16. The upper screen. is then slipped in, and the lower screen slightly raised. so that its upper projecting strip will be caii ght above the lower molding of the upper screen,

and both screens are pushed up into the socket until they lie above the opening for the piece 22. The piece 22 is then set in place, and positioned so that when the upper screen molding lies partly in the pocket, the depending angle strip on the lower screen will seat on the sill of the window. it is sometimes necessary to shift the lug 23 and drill the hole for it in piece 22 after the screens have been tried. Thus it can be seen that screens are provided which willv easily slide up into the pocket of a window, without leaving any dust entrance into the pocket through the opening for the screen.

To prevent the dropping of the screens in the channels and to avoid the necessity of placing springs on the screens as is the customary practice, the channels are fitted with springs as follows :Alongside of the insert of the channels is set the spring 40, and above it and in the insert itself is placed. the spring 41. These two springs take up the jar which would result from the sudden dropping of the screens from the pocket, and springs ll act as a protector against the bolts 28, as does the beveled face of the lug 22.

Also it is plain that screen channel guides are provided which can be set into pocket windows and removed and replaced without difiiculty, these guides being mountedpreterably on the outer sash guide rail, thereby narrowing the necessary width of the pocket. If desired. some method of counterbalancing the screens could be provided for, although this is not insisted upon.

The various details of the above structure could readily be modified without departing from the spirit of the invention herein.,- and it is not desired that limitations oi the claims be implied because of failure to mention such equivalent structural modifications, nor is it desired that this invention be limited to the mounting of wire screens only since blinds or shutters for screening or shading purposes could be mounted in the same manner.
