UNlTED STATES PATENT HARRY DIXSON, OF PELLA, IOWA, ASSIGNOR TO ROLSCREEN COMPANY, F PELL,
A IOWA. Y
Application led December 5, 1927. Serial No. 237,804.
The object ot my invention is to provide a guide construction for rolling window screens wherein a flange on one edge otl thc guide is so arranged that when the guide is painted, the paint will not enter the interior of the guide, the .parts being.. simple,
- durable and comparativelyinexpensive.
More particularly it ismy object to provide a guide for the edge ot' a screen upon which is arranged' a pairo'l' channel shaped flanges opening toward cach other and between which the screen is adapted to travel and which channel shaped flanges receive any paint which may by capillary attraction enter into the interior of the guide when the outside thereo'tl is being painted.
Still a further object is to provide the channel shaped flanged edges of the guides with one side or leg thereof being slightly longer than the other and thus coming closer to the corresponding side of the opposite portion of the guide so as to enage the screen traveling therebetween w lille the other or shorter leg of each channel shaped flange is spaced from the screen on each side thereof.
My invention is particularly' adapted for use in connection with rolling window screens of the kind disclosed in my copending application filed May 13, 1925, Serial Number 29,960.
With these and other objects in view, my invention consists in the construction, arrangement and combination of the various part-s of my guide construction for screens, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 is a plan view of a portion of the screen with' my improved guide shown thereon.
Figure. 2 is a sectional view taken on the line 2--2 of Figure 1, clearly disclosing the shape of the guide and particularly the channel shaped flanges.
Figure 3 is an enlarged sectional view through the track and screen together with a portion of a paint brush showing the position it assumes when the outside of the track is painted.
Figure 4 is a detail sectional perspective view of a portion of the guide construction.
In the accompanying drawings, I have used the reference character A to indicate shaped flanges 28 open generally a guide construction which may he formed of a single blank of material bent substantially midway between its side edges as at l() for forming a pair of abutting flanges l2 and 14.
'lhe abutting flanges 1L. and 14 as clearly shown in Figure 4 of the drawings, form the fastening flange ot' the guide construction. 'lhe sides or track fastening flange formed ot' the members 12 and 14, is formed with an elongated slot 16 through which a .screw or the like 18 may be mounted wherein the guid construction is bodily capable of movement laterally.
rlhe guide construction is used in connection with a rolling window screen 20 and a pair of guides are mounted upon a frame 22. 'lhe two guides used with cach rolling window screen' are mounted so that they open toward cach other.
Each ol`- the free edges of the flanges 12 and 14 are oppositely curved as at 24 for providing' a tubular screen edge receiving guide 26. I have shown the tubular portion as formed substantially circular in outline although other shapes may be'equally as well used. The tubular portion 26is formed with a slot 27 running lengthwise of the guide. l
Upon each of the free edges of the por# tions 24 and adjacent the slot 27, I provide channel shaped flangesl 28. The channel toward each other as clearly illustrated in Figures 2 and 4 of the drawings. The channel shaped flanges 28 are formed integral with the portions 24 and are connected thereto by a curved portion 30 which curved portion really forms one leg or side of each of the channel shaped flanges 28.
This side may be referred to by the reference numeral 32 andthe other side, by the reference numeral A34.
The side 32 is somewhat longer than the side 34 and due to the fact that each of the flanges 28 open toward each other, causes the two curved portions 30 of the opposite flanges 28 to be positioned somewhat closer together than the edges of the sides 34.
The screen 20 is received between the two curved portions30 and has its edge received within thel tubular guide 26. The screen will be provided with enlarged portions 36 wherein it will be normally retained within the guide although, as a matter of fact, the
enlarged portions 36 may be pulled through between the two curved portions 3() of the guide construction, the curved edge or surface as at 38, allowiiigthis to be done without mutilation of the screen or the guide construction.
The channel shaped flanges 28 which form the primary feature of my present invention, are so arranged that when the outside of thc guide construction is painted, the brush as at may fit up against the guide and when the entire outside thereof is painted very little paint will entei` into the guide proper.
It may be here mentioned, that paint entering upon the curved portion 3() oiupon that -portion which may coact with the screen, is detrimental to the easy and free operation of the screen up and down in the guide construction.
The channel shaped flange 28 eliminates this possibility in the following manner. In the first place, the entire curved outer edge of the flange 28 may be painted in the inanas represented by the brush 40. Some little paint will by capillary attraction pass into the interior of Athe channel shaped flange or upon the edge of the leg 34.
The travel of the paint by capillary at-' traction is represented by the dotted lines 42. It will be noted that this leg 34 terminates short of the screen 20 so that even it' paint does enter therebetweenuas represented by tlie reference numeral 42, it will not come in contact with the screen or interfere therewith.
The channel shaped flange 28 provides a break between the portion 30 and the outer edge of the guide construction. It will be readily seen'that paint will not enter or travel. into the guide construction proper and come in contact with the portion 30 when the outer sides of the guide receive an ordinary application. of paint. Any paint that may accumulate upon the interior of the guide construction will fill the channel shaped groove 44 which is formed by the channel shaped flange -28.
The accumulation of paint therein will cause no harm to the use of the'screen.
It has been found with guide constructions where no paint receiving pocket was formed on the interior ofthe guide construction that at the timewhen the track wasv painted, a certain amount of paint would enter the screen and within the track or guide and when the paint became dry it would stick and the screen would not oper-l ate freely. l
My present guide construction including l protect the slot in the when the outer surfaces of the flanges are the channel shaped flanges eliminates this undesirable feature and I have found in actual practice and use of my present track construction, that it does prevent paint from entering into the operating part of the guide construction.`
Some changes may be iliade iii the construction and arran ement of the parts of my device without ieparting from the real spirit and purpose of my invention, and it is iiiy modified foi-ms of structure or use of mechanical equivalents, which may be reasonably included within tlieii'scope.
I claim as my invention:
1. A guide construction comprising a tubular lguide portion, a fastening flange on one side of saiduide portion, said guidel portion having a slit opening therein running lengthwise thereof and a channel shaped inwardly opening flange mounted on e'ach edge of the slit opening.
2. A guide for the edge of a screen comprising a pair of similar members oppositely spaced for forming atubular other side having spaced projecting channel shaped flanges.
3. A guide having a longitudinal slot, the
guide having adjacent to theA slot, spaced .bnlar guide portion, a fastening flange `on one side of said guide portion, said guide portion having a slit opening therein running lengthwise thereofl and a flange mounted on each edge of the slitopening, the last mentioned flan es being spacedfor a portion of their widt is a greater distance guide having lat one side flat fastening-'flanges and the than the width of said slit opening and having their inner other.
5. A guide having a longitudinal slot, the guide having adjacent the slot spaced flanges, each of which have portions projecting outwardly from the slot and having portions of ltheir inner surfaces facing each other whereby the outer edges of the flanges guide against paint surfaces facing veach painted. j
6. A guide having a longitudinal slot, the guidehaving adjacent to the slot, a channel shaped member opening inwardly whereby said channel shaped member prevents paint from entering upon the edge i and for the purposes stated.
