CONRAD A. JOHNSON, OE JAMESTOWN, NEW\YORK-.

Application filed Ma 1, ieie. Serial No. 94,579.

To all whom it may concern:

Be it known that I, Comm) A. JOHNSON,

a citizen of the United States, residing atthe city ofnlamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improve- I 'ments in Window-Screens, of which the following, taken in connection with the accompanying drawings, is a specification.

The invention relates to hollow sheetmetal window and screen frames, and the object of the improvement is to provide-a.

simple-and strong sheet metal frame for both window .andscreen construction in which a rib is raised from the sheet metal 7 lengthwise of the frame side and atubular.

slotted piece is slipped onto the same to ex'- 'tend over and. hold the screen fabric and claimed.

filling strip and: also serve for a holding strip for by provi the spring for the guide strip. Fig. 3 is a perspective view of a-portion of the'top or bottom side of the screen frame showing the construction ofthe'same and the arrangement of the raised 'rib along the sideofsaid screen frame and the tubular covering strip for said raised rib.- Fig. 4 is a perspective view of the angular cornerbrace. F1g. 5 is a perspective view of a portion of the tubular slotted flat sheet metal cover and holding strip. Fig. 6 is a modification of the holding strip shown in Fig. 5; and Fig. 7

shows further adaptation of said modification shown in Fig. 6 with the modified form of the screen side adapted to receive a guard wire or window glass and hold it firmly against the frame side and the grooved edge and guide stri Fig. 8 is a perspective view 0 one oft e springs for engaging the guide strip.

The numeral 10 designates the tubular sheet 'metal frame sides which are-preferably made of one strip of metal folded cen- -trallylengthwise at the inner point 11 and Patented Aug. 7, 917.

the contiguous folded inner portion -formed in a lengthwise groove13 opening sidewise along the inner edge to receive the filling strip 14, which-is preferably of wood for the screen fabr1c'15. The remaining portions of the strip of metal are formed in a 'lehgthwise 'tube ,and the two edges are united. on: the outer side in the top and bottom sides in a flat return bend or double seam 12, as shown in Fig. 3.

a The lateral frame sides 20 are usually provided with lengthwise grooves 28' in their outer edges "to slidably receive the gu de strips 29 therein, one at each side. The groove'28 is formed by shaping areturn bend'in one edge of the sheet metal strip which bend is spaced so as to interlock with a lengthwise return bend in the other edge, and the three thicknesses of sheet metal so placed together at 30 are then united by spot welding or similar means so, as to attach the sheet metal edges firmly together. The leaf springs 31 are attached walls of the'groove .28 thereby holding the spring 31 with freedom of movement at its unattached end. The, central outwardly curved portion .of the spring 31 bears agains the guide strip 29. The guide strip 29 may be made in any suitable manner so that it is stifl' and strong.

To cover the strip 14 and groove 13 a T- shaped rail or rib 17 is bent from the sheet I metal tube side into the flat T-shaped form lengthwise alongthe inner edge of the groove 13 and a flat tubular sheet metal str p 18'1s provided with a lengthwise slot 19 which fits over the rib 17 and onto the neck or stem 16. The inner, edge of the flattubular strip 18 is extended over the groove 13 and, ontothe edge-of the sdreen fabric'15 thereby covering the groove 13 and the manner of. attaching the screen fabric to they screen side, protecting the same from the elements and retaining the filling strip and I screen fabric inwpositioii.

In the modification of the frame side shown inFigs. 6 and 7, the tubular frame side 20 is formed from one strip with the 10 groove-13 along its inner edge and with the shaped rib 17 along the/groove 13 and the inner edge of the tubular frame side 20'. The

' tubular retaining strip 21 is provided with the attaching lengthwise slot 19 .to receive the rib 17 therein the same as strip 18. The

' change in thelformation of the strip being the angular bend 22 along the-inner portion 23 to provide for the reception of the

edge

10 and 20 fitting closely within the same so that said frame sides may be soldered tothe angular brace 26 thereby attaching said frame sides strongly to one another. The

filling strips 14 are preferably not mitered,

it being easier to fit said filling strips 'to' place if square ended, as also the ,coverstrips 18a as shown in Fig. 1. The frame is pro- ;vi' ed with lifts 27 for sliding the frame up and down, one ofthe lifts 27 beingpreferably placed on the side opposite the springs 31 to aid in placing the frame on the guides 'When it isnece'ssary to insert a cross .piece 34L in a screen frame, it isof course essential that it should have the wire attaching groove 13 on; each edge, as shown a inlFig. 9. 'The cross piece 34 is preferably made of twoistrips of sheet metal with the groove 13-bent in each edge of ,one of said strips and the other strip bent channel shaped over the turned up edges ofthefirst strip and spot welded at 35, thereby'holding the two strips firmly together. Two paralle.

spaced ribs 17 are bent up the sheetto slidably recelvethe tubular-1 strip 13 thereon and substantially abut one; a another so as to give a metal so as leasing afpearance for the grooved side of e ea-i. '8

7. In a screen, a frame, a cross-piece having a pair of longitudinal grooves, wire in the grooves, filling strips for vholding the wire in the grooves, ribs adjacent the pair of grooves, and strips slidably fitted over the ribs to cover said grooves and filling strips.

8. In a screen, a metal frame the sides of which are centrally folded lengthwise to provide grooves opening outwardly on the front face of the frame, said sides being further folded to form side edge grooves one of the walls of the latter being formed of an intermediate folded part and the other wall being formed of interengaging edge parts of said sides to provide a wall of three thicknesses, screen fabric in said first grooves,

and fillingstrips to hold the fabric in position. 1

9. In a screen, a frame having grooves .to receive the screen fabric, filling strips for holding the fabric in the grooves, finishing 'strips extending over the strips and concealoverhanging said first named grooves to enable a guard or the like to be'engaged with and held in place by said overhanging parts. 10.
