UNITED STATES HARRY DIXSON, OF DES MOINES, IOWA, ASSIGNOR TO ROLSCREN BOLLING-WINDOW-SCREEN CONSTRUCTION.

Application led May 13, 1925.

The object of my invention is to provide a rolling window screen of simple, durable and comparatively inexpensive construction.

More particularly, my invention relates to a rollin; r window screen adapted, when in inoperative position, to be tightly Wound around a shaft and encased in a casing, and when in use, to cover the window opening and be held comparatively taut from side to side and from the bottom to the top of the window casing.

Still a further object is to provide a spring roller construction upon which the window screen may be wound, which spring roller construction can he easily and conveniently assembled 'for reducing the expense of the window screen construction.

Still a lurther object is to provide a spring having one end slightly contracted so as to lsnugly fit around the shaft or rod, upon which it is mounted` and the major portion ot thc spring to be free from the rod, that is, greater in inside diameter than the diameter otl the rod upon which it is mounted.

Still a further object is to provide a casincr for the screen when in rolled position, which casing has formed thereon, end members which serve to strengthen and reinforce the casing, as well as to serve as a bearing for the rolling window screen.

Still a further object is to provide a pair of spaced guides in which the edges of the screen are permitted to travel, the edges having clips stapled therein at spaced intervals t'or maintaining the screen in position against accidental withdrawal from the guides.

Still a t'urther object is to provide a rolling window screen wherein the retaining means for normally holding the side edges oi' the screen within guides may be automatically returned to the guides in the event they are pulled from the guides by undue pressure being applied against the screen, the return being a.' complished by providing suflieient spaces above the guides or below the screen casing adjacent the guides so that the retaining means may pass through Asaid open .spaces and into proper alignment with the guides when the screen is rolled up.

Still a further object is to provide a guide iilock of slightly greaterdiameter than the inside diameter of the guides for traveling therein. and causing them to slightly eX- pand when the guide block is moved up and down, the guide block trictionally engaging Serial No. 29,960.

within the guide for serving aS a stop or retarding means against the action of the spring forming a part of the rolling window screen construction and at' the same time to so mount the guides that they are capable ot' adjustment towards or from each other whereby the binder strip tends to automatically adjust the guides as the screen is rolled up or pulled down.`

Still a further object is to provide a pair of spaced, flat flanges at'the opening in the guides for preventing any binding o'r otherwise interfering with the free up and down movement ot the screen proper when operated.

Still a further object is a provide a rolling window screen construction for use in connection with the so-called easement windows, the window screen in the easement window being mounted on the inside'of the window. i

With these and other objects in View, my invention consists in the construction, arrangement aud combination'of the various parts ot my device, whereby the objects contemplated are attained, as hereinafter more fully set, torth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 19 is a detail, perspective view showing the mounting of the casing relative to the guides when used in connection with a easement window.

In the accompanying drawings, I have used the reference character A to indicate generally a window frame which includes the upright members 10, a top cross member 11 and a sill 12. A

The window frame includes the ordinary guide strips 13 and divider strips 14, between which the upper and lower window sashes are permitted to slide as in the ordinary window frame construction.

My improved rolling screen construction includes a casing 15, which is substantially rectangular in cross section, as clearly shown in Figure 4 of the drawings, although casings of any suitable shape may be employed.

The casing 15 is formed of a single blank of material folded along three lines so as to form the four sides of the casing.

The edges of the casing 15 are doubled upon themselves, as at 16, and are slightly spaced apart so as to form a screen opening 17.

End bearing caps 18 are inserted in the casing 15, and are spot welded or otherwise secured to the four walls of the main body portion of the casing 15.

The bea-ring caps 18 are formed with four outturned flanges 19 so as to make the bear ing1 caps 18 substantially like an open receptac e.

The outturned flanges 19 serve as a means for fastening the bearing caps 18 to the remainder of the casing 15.

The out-turned (langes 19 and the casing 15 are formed with registering slots 20 through which may be extended screws 21, as will hereinafter be more fully explained for the purpose oli-fastening the casing 15 on to a window frame A.

A bearing cap 18 is placed in each end of the casing 15, and each bea-ring cap 18 is formed with a central opening 22, through which is extended the ends of a rod 2?.

Cover caps 23 substantially as shown in Figure 9 of the drawings are used for covering the two outer ends of the casing 15.

The cover cap 23a is formed of spring material and may be sprung sufficiently for permitting it to frictionally engage the casing 15 when in installed position.

One flange of the cover caps 23a is formed with a pair of outstruck portions 24, which are of suficient size to accommodate the heads of the screws 21, as clearly shown in Figure 5 of the drawings.

The casing 15 is set against the window frarne between the two upright members 10, and against the guide strips 13 thereof and just below the top cross piece 11.

The screws 21 are extended through the slots 20, and extend into guide strips 13 as well as the upper frame work of the window frame A for properly anchoring the entire casing on to t-he frame A.

The provision of slots in all four sides of the casing 15 permits the use of screws 21 in either vertical direction or in a horizontal direction, whereby the casing may be properly anchored.

Ordinarily, however, the screws 21 are arranged in horizontal position due to the fact that there is no overhanging part of the frame A above the casing 15.

Mounted within the casing 15 and between the bearing caps 18 is a spring roller construction B including a tubular shaped member 25 to which a sheet of window screen 26 may be fastened in any suitable manner.

The tubular member 25 has a pair of caps 27 placed in its ends` which caps have openings therein of sufficient diameter to receive the rod 23, all as clearly shown in Figure 10 of the drawings in section.

The rod 23 is slotted in each of its ends, as at 28.

The slotted ends will be hereinafter more fully explained.

A coil spring 29 of greater diameter than the rod 23 is received within the tubular member 25, and has one end extended through one slot 28 in the rod 23, and has its other end, as at 30, extended through the tubular member 25, thus anchoring one end of the coil spring 29 relative to the other.

In order to prevent rotation of the rod 23, I insert a pin 31 in the slot opposite the end of the coil spring 3() that connects with the rod 23.

The pin 31 is arranged diagonally in the casing 15 so that when inserted, will positively retain the rod 23 against any possible rotation.

The coil spring 29 at the end which connects to the rod 23 is contracted, as at 32, so as to lit rather snugly against the rod 23, leaving the remainder of the coil spring Q9 free from the rod 23.

The purpose of making one end of the coil spring 29 tight around the rod 23, and the remainder loose is to allow the coil spring to tighten when the screen is withdrawn without causing any undue binding of the spring relative to the rod Fixed to the actual surfaces of the guide Strips 13 are screen guides C. The screen guides C are preferably formed of two similar members, each having a flat portion 33 and a substantially semi-circular portion 34.

The two similar members of the screen guide C are placed against cach other with the semi-circular portions 34 facing each other so as to form a substantially complete tube in which the edges of the screen 26 are permitted to travel.

The free edges of the semi-circular portions 34 are extended away from such portions to form parallel tianges, as at 35, and are spaced a slight distance apart so as to permit the screen 26 to travel therebetween, as clearly shown in Figure 3 of the drawlngs.

The lower edge of the screen 26 is formed with a binder strip 36, which is formed of a flat sheet of metal bent upon itself so as to form two thicknesses between which is received the screen 26.

The hinder strip 36 is then bent between its top and bottom edges for 'forming a suhstantially L-shaped strip in cross section.

The two sides of the binder strip 36 are spot-welded together and also spot welded to the screen itself.

Guide blocks 37 extend over the side edges of the binder strip 36 and are adapted to travel in the screen guides formed by the two semi-circular portions 34.

rlhe guide blocks 37 include a pair ot flat parts 38, which travel between the two flat portions 35 of the screen guides C.

The guide blocks also extend around the binder strip 36 and are spot welded thereto.

The edges of the screen 26 are stapled with clips 89 which are formed with a central hump 40 for insuring the screen 26 to remain within the screen guides C.

The clips 39 are spaced at various intervals along the marginal edges of the screen 26 and thereby do not interfere with the screen when in rolled position.

The guide block 37 is of such diameter 4that when inserted in the semi-circular portions 34. it will cause them to be slightly expanded, thus causing the two parts of the screen guide C to frictionally engage the uide block 37.

The screen 26 passes out of the casing 15 through the screen opening 17.

The rolled edges 1G of the casing 15 prevents any sharp edges from coming in contact with the screen itself.

The screen guides C are Formed with a number ot' slots 41 through which are cxtcnded screws 42 whereby the screen guide C may be slightly adjusted toward or from each other for taking care of any slight variation in the width of the window frame A.

l The upper edges of the screen guide C rest aga-inst the underside of the casing 15 and the opening in the upper ends ot the guides C are in substantial register with the screen opening 17.

The upper ends ol the semi-circular portions 34 of the guides C are cut at an angle or beveled as at 43. for pern'iitting the easy insertion ot the guide block 37 into the semicircular portions 34.

The beveled edges 43 also permit the screen Q6 to pass in between the two flat portions 35 without any danger of the clips 39 beingr caught or binding.

Along each side of the guide strips 13 near the lower edge thereof. I place spring locking bars 44. which are adapted to spring over the lower portion of the binder strip 36 and engage it for retaining the screen in its lowered position against the tension of the spring 2 Each locking bar 44 is fastened to the guide strip 13 by means of a screw 45 eX- tending through a slot 46.

The slot 46 permits slight the locking bar 44.

In this connection it may he mentioned that in the use ofthe rolling window screens manufactured on a. commercial basis, it is necessary to provide for adjustment ot' the parts in order to take care ot' any variations in wood trame construction used in building art.

rl`he tension of the spring Q9 may he varied by removing the pin 31 and then rotating the rod Q3 against action of the spring.

A locking pin 47 may be inserted through one end of the rod Q3 for preventing the removal of the rod Q3 when the parts are being assembled.

In Figures 11 and 1Q. I have shown an arrow 43 to indicate the direct-ion ot the tubular member 25 when the screen Q6 is withdrawn or moved to its operative position where it covers the window opening.

In Figures l5 to 19 inclusive, I have .shown my rolling window screen construcadjustment of tion applicable to easement windows. Casement windows ordinarily open outwardly, and it is therefore necessary to mount the screen on the inside of the house or building. It is also necessary in view of the handle and other hardware upon the Casement windows to mount the screen a sufficient distance inward of the easement window so as to clear any such hardware, and in thc drawings I have used the reference numeral 49 to indicate an ordinary Casement window of either wood or steel construction.

Locking handles 50 are provided on the easement windows 49, and engage the upright dividing bar 51.

In some easement windows the bar 51 is omitted and the two easement windows simply fasten to each other. In this form of construction, the screen guides C are formed with an extension 52 arranged at right angles to the line of the screen 26, and this portion 52 terminates in a second portion 53 arranged at right angles to the portion 52.

The portion 53 is formed with slots 54 whereby screws may be extended therethrough for securing the screen guides'C to the easement window frame 55, which may be of either steel or wood.

The portion 52 causes the position of the screen to be a sufficient distance forward of the casement windows 49 so as to revent any interference with the -screen y the hardware upon the easement window.

The portion 52 of the screen guides C rests against the plaster or against the actual frame of the building in which the Casement window frame 55 is mounted.

The screen guide C shown in Figure 18 of the drawing is formed of two pieces similar to the one shown in Figure 3 of the drawings, and in this case the inner one terminates somewhat short of the outer one so as to receive the casing 15 thereon, as clearly shown in Figure 19 of the drawings.

The outer part of the screen guide C serves as an end cover plate for the casing 15.

In order to provide additional supporting means for the casing 15, I provide a slidable bracket 56 positioned between the inner and outer members of the screen guide C and adjustable thereto by the slot and bolt connections 57.

The casing 15 may be built right in the plaster work of the house or building, and when so built in, the plaster will come down to position substantially as shown. by the dotted line 58 in Figure 16 of the drawings.

The space between the semi-circular portions 34 and the portions 53 of the screen guides C may be filled in by the use of a filler block 59, thereby practically concealing the portions 52 and 53 of the screen guides C.

The locking bar 44 is formed with an oset flange 60 permitting it to be properly secured to the screen guide C where it will properly coact with the binder strip on the lower edge of the screen.

It will be seen that I have provided a very efficient rolling window screen construction adapted to be used either in combination with a wooden window frame wherein the windows slide, or either in connection with a easement window where the windows swing outwardly.

Then the rolling window screen construction is used with a Casement window, it may be built in with the house, and practically unnoticeable, and will not in any way interefere with the beauty of the walls adjacent the Windows.

Some changes may be made in the construction and arrangement of the various parts of my invent-ion, without departing from the real spirit and purpose of my invention, and it my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.
