GUIDE FOR ROLL SCREENS Filed may 10. 1929 A TTORNEYJ Patented Oct. 4, 1932 i UNITED STATES PATENT oFr cE CLIFFORD TRAUT, OF NEWPORT; KENTUCKY, ASSIGNOR TO THE HIGGIN MANUFAC- TUBING COMPANY, or nEwroEr, KENTUCKY, A CORPORATION or WEST VIRGINIA GUIDE Eon EoLL SCREENS Application filed May 10,

This application has to do with the provision of simplified and less expensive guides for roll closures and is a continuation in part of my application Ser. No. 262,417, filed March 17, 1928, patented March 4, 1980, No. 1,749,199.' The objects of my invention further comprise the provision of guides having a slot to hold the edges of the screen cloth or other closure material and to per mit the passage of an attachment member, and a channel wherein is slidably held a guided member.

These and other objects of my invention which will be set forth hereinafter or will be apparent to one skilled in the art upon reading these specifications, I accomplish by that certain construction and arrangement of parts of which I shall now describe two preferred embodiments, reference beinghad to the drawing which accompanies this specification.

In the drawing:

Figure 1 is a perspective view of one form of my guide.

Figure 2 is a perspective view of a draw bar and guided member adapted to be used therewith.

Figure 3 is a View showing in section the guide and illustrating the cooperation between the guide, the guided member and a draw bar.

Figure 4 is a view of my guide.

Figure 5 shows a type of draw bar and guided member suitable for use in the guide of Figure 4:.

Figure 6 is a view partly in section showing the cooperation of the several parts when the guide of Figure 4 is in use with the draw bar and guided member of Figure 5.

Guides for roll screens have hitherto been produced for the most part by bending a single strip of metal to form a channel of circular cross section having a slot therein at the side, opposite an attachment tongue, the edges of the slot being rolled and double thickness, the attachment tongue formed of two parallel but unjoined parts. Guides of this character are expensive to construct by reason of the complex bending operation a modified form of 1929. Serial No. 362,095.-

necessary upon the metal and they are somewhat restricted in their usefulness because the channel section has comparatively a small depth and surface andis not adapted upon the one hand to allow any great play in the guided member, and on'the other hand is not adapted to give an absolutely positive guiding action where that type is desirable, eX- cepting the guided member be of comparatively great length.

' In my invention I provide a guide which is simply and inexpensively formed by a much less complicated bending operation, and which may, if desired be formed of two pieces of sheet metal bent to a simple shape 1 andwelded together. In Figure 1 I have shown a back piece 1 bent at right angles as at 2 to form a channel side. The outer edge of the portion 2may have a turned over lip 3' if desired. A second piece of metal is bent to form an. attachment portion 4 adapted to lie alongthe portionla ofthe first strip, a portion 5 which is a channel defining side, a portion 6 to close'partially the front of the channel and a reentrant portion 7 to lie v parallel to but spaced away from the portion 2 of the first strip. The two strips will be attached together, as is conveniently done by spot welding at intervals, indicated at 8. It is equally as simple, and in many cases preferable from a manufacturing standpoint to makethe entire guide from a single piece of metal, and I have so illustrated it in Figure 3.

It will thus be seen that this form of guide provides a channel, a slot and an attachment tongue. In the embodiment of Figure 1 the attachment portion extends at right angles to the longer axes of a cross section ofthe slot. This form is useful where the guide is to be placed against an upright and fastenedthereto. The attachment tongue may however, be caused to lie at any angle to the" channel forming portion. Dotted lines in Figurezl show it lying in the plane of the portion 5.

In'Figure 2 I have shown a draw bar 9 which may beof any construction desired. In the embodiment shown it is formed from a bent section of sheet metal having a channel for thescreen attachment as indicated at 10. This construction does not form a part of my present invention; but in the type of draw bar illustrated in Figure 2, the hollow. inside of the bar offers a convenient means for the attachment of the guided member, The guided member may alsobe formed of a single piece of sheet metal bent to provide a back section 11 adapted to pass through the channel between the members 2 and 7 of the guide. This member will have a portion 110 adapted'to enter the interior of the draw bar, and it may be provided with tongues 12 to steady it therein. The guided member will then be bent so that theend opposite the member 11a will be given substantially a box shape as shown, comprising an end 13, a side portion 14, an end 15 and a reentrant portion 16. A curved spring 17 may beused with this type of guided member, where desired, to increase the friction and to hold the parts in better'contact and alignment. Figure 3 will indicatethe cooperation of the various parts when the guided member is in use in the guide. The portion v11 will pass through the slot between the guide face 2'and the reentrant guide portion 7 The end 13 will lie next the back 1 of the guide. The side 14 will lie next the side of the guide. The reentrant portion 16 of the guided member will lie next the reentrant portion 7 of the guide; and between the front portion 6 of the guide and the front portion of the guided member there will be the spring 17 pressing the remaining parts into tight-engagement.

A difierent modification of my guide is shown in Figure 4 in which the back portion 1a is straight and forms both a portion of the attachment tongue and a channel side. The outer edge of this piece is turned over as at 18 in'the channel defining portion. The second metallic piece has a portion 19 forming the other part of the attachment tongue, a portion 20 forming the back of the channel, a portion 5a forming the other part of. the channel side and aportion 6a forming the front of the channel. The outer edge of this piece is preferably turned out again as at 21 so as to lie parallel with 1a,a nd the extreme edge is turned over as at 22 in the slot defining portion. Again dotted lines show a different angular relationship of the attachment tongue. The guide may be made in two parts as shown in Figure 1, or from a single sheet metal piece as shown in Figure 6.

"Vith this type of guide I may use the same draw bar and guided member shown in Figure-2; but aseparate type of guided member is advantageous. This is shown in Figure 5 and is useful .where' a more positive guiding action is desired than that in the first modification hereinabove described. Here a draw'bar 9a of the same typeas 9 is fitted with a guided member having a back 11? joined to a box section having a back 23, end

pieces 24 and 25 and a side 26. This box section may be made quite closely to fit the channel section of the guide of Figure 4-. so as to be positively guided thereby and held against angular displacement. A spring 27 may fit in this instance within the box section and may, bear against the front 6a of the channel as is shown in Figure 6, wherein is illustrated the cooperation of the several parts. i v Y j Various modifications of my invention may be madewithout departing fromthe spirit the attachment tongue part of each and the front of said channel being semi-resilient.

2. In a guide of sheet metal for roll closures, a portion bent to form the back of a channel and an attaching tongue piece whichlie in the same plane, and the side of the channel lying in a different plane, a second'portion bent to form an attaching tonguepiece, the other side of said channel anda closure for said channel, said closure being semi-resilient and having a reentrant tongue defining a slot in said I channel, the

outer edge of said. first mentioned portion turned over to form a lip, said two portions disposed so astobe parallel and contiguous in the attaching tongue part of each.

3. In a guide for roll closures, an attaching tongue, and a wall and a lip extending in substantially' a single plane and attached to said tongue, a second attaching tongue parallel with and contiguous to the first mentioned attaching tongue and a resilient channel with one longitudinal edge joining said second attaching tongue and having its opposite edge free and extending along said lip and spaced therefrom to admit a member for guidance in said'channel.
