HENRY W. WATSON AND WILLIAM W. WATSON, OF JAMESTOWN, NEW YORK.

METALLIC SCREEN.

To all whom it may concern:

Be it known that we, HENRY W. WATSON and WIL IAM W. WATSON, citizens of the United States, residing at Jamestown, in the .county of Chautauqua and State of New York, have invented certain new and useful Improvements in Metallic Screens, of which the following, taken in connection with the accompanying drawings, is a specification.-

The invention relates to improvements in sheet metal window and door screens, and is an improvement upon our former screen construction as shown in Letters Patent No. 956,239 of April 26th, 1910; and the pbject of our improvement is to provide a simple and strong sheet metal frame construction which provides against injury from rust or corrosion and may be easily and quickly assembled; andthe invention conslsts in the construction and arrangement of the parts as shown in this specification and the accompanying drawingsgand pointed out in the claims.

Fig; 7- is a sectional view. at line X X in Fig. 2, showing the construction of the top rail with the screen fabric attached thereto. Fig. 8 is a side elevation, and Fig. 9 an edgewise elevation, of the inner corner brace. Fig. 10 is an elevation of one of the lower corners of the frame. Fig. 11 is a sectional view at line Y Y in Fig. 10, showing the construction of the upper edge of the lower cross rail. Fig. 12 is a perspective view of a portion-of the beveled strip which is attached overthe upper edge of the lower. cross rail to prevent injury to the screen frame. Fig. 13 is an elevation of the central portion of the lower cross rail with the beveled strip'attached along its Specification of Letters Patent.

upper edge and a catch or draw, inserted in cross rail or frame side, and the numeral 23 the lower cross rail or frame s ide.- The erably formed with solid tubular construc'-' tion, having the inner edges 241 united and folded one over the edge of the other and bent in the form of an angular flange to form the channel 25 which extends entirely around the inner side of the frame, for attaching the screen fabric 20 thereinby means of the split tubular strip 26 which is sprung into the groove 25, groove 25 being narrow at the mouth and enlarging inwardly. The tubular frame sides are prefcross rails and lateral frame sides are pref-- erably made of thin sheet metal, since it forms a rigid and strong frame. In order- -to protect the folded ed cs 24 of the frame sides froni rust, a folde stri 27 of bronze or non-corrosive sheet metal is folded with inturned lower edges, so that it may be slipped onto the folded edges 24 and whenin place aids in the correct-formation of the groove 25, contracting the mouth of the groove and giving it a greater enlargement inwardly. The water runs down the wires of the screen fabric and rests'upon the uprosion be permitted. The bronze-strip 27 entirely overcomes this difiiculty andis prefper edge of the lower rail and drips down erably placed over the edges 24,aro1ind-the.

entire screen frame with the exception that on the edge 24 of'the lowercross rail 23 it is preferably broadened and givenfla bevel as shown at 28. This arrangement causes the water to flow out down the bevel and not stand on the horizontal upper edge of frame side 23, and also prevents careless people from. racking. the screen frame by catching hold of one corner of the frame to pull it down since the bevel gives no finger hold. The beveled strip 28 is formed with the inner lip or flange 29 which catches within the folded edges 24 and extends" vertically alongside the screen fabric on the side 30," then extends on the downward bevel-to the other side of the rail and is attached by soldering or brazing at 31,} thereb' bracing and strengthening said lower ra1l and performi and the sides of thebox 33 each" side are indented for the flatends 34 which are brazed or soldered in'plac, thereby holding strongly upon the'box 33. This leaves the open side 36 of the box as so that'a hook 37 may be inserted around catch 32 for drawtends the full len ing down the screen. The box 33 is insert-- ed in the lower edge of the rail 23 with the opening 36 in said side so that thehook 37 may be inserted, thereby insuring the accurate drawing .of the screen from itscentral portion. Thecorners of the screen frame are'made in the followin -manner: The frame sides are mitered wit the exception of the sides of the inwardly bclfit oove 38 which exout against the inner side of the adjoining frame side. An inner brace 39 is constructed as follows Two triangular. sides of sheet metal are connected'a portion of the length of the one side,the sheet metal bein bent in line with the side of the trian le. he connectingl portion 40is of suflicient len th to press t e triangular sides of brace 39 rmly against the inner sides oft-he hollow tubular mitered ends. Theconnecting side'40 is cut away for aportion of.the length in order to provide two free ends of the triangular sides of thebrace'which shall extend in each side of the projecting groove portion 38, as shown in Figs. 3 and 4, just suflicient space being allowed between the sides of the groove portion 38 and the outer sides of the tubular rail to receive said ends of the sheet the frame side and metal brace 39. In assembling the corner ends extending out in lugs which are insertible through the slots 43 in the flanges 24 and are then bent against the inner sides of, the flanges 24.. In order to so brace across the corner it is necessary that the inserted ends shall continue along the inner flange side toward the center of the frame and not toward the corner, since if ent backward toward the mitered corner the end of the brace would be in the line of the strain and not holding against said strain as when bent as shown in F ig. 17. The brace 42 is inserted' when the corner is assembled with the inner brace 39 in placeand before it is referably curved in its soldered, and the solder is preferably flowed into thg space 44 between the brace 42 and the corner formed by the flanges 24, thereby forming a strengthens said corner. It is apparent that in a large screen frame it is necessary to solid brace which greatly construct the light tubular frame sides as rigidly as possible, or the frame will be a failure. This construction of the corner gives great rigidity and yet is simple and easy to assemble.

We claim as new: p

In a screen, a frame consisting of tubular side and end pieces, a lengthwise flange on the inner edge of said frame foiming a lengthwise recess on said tubular side and end pieces, a folded strip of sheet metal over the edge of said flange, screen wire, and means for holding said screen wire in said recess over said folded strip.

2. In a screen, a sheet metal frame consisting of side and end pieces having a lengthwise recess on the inner edges formed by the edges of the sheet metal, a folded strip of sheet metal fitting over said edges, screen wire, and .means for holding. said screen wire in said recess over said folded strip. A

4. In a screen, a rame'composedof'sheet metal tubular sides, the corners of said frame mitered, an internal corner brace composed of connected sheet metal side plates spaced to fit against the opposite inner sides of the mitered tubular ends of the frame sides and connect the same, said mitered ends attached to said internal corner brace.

5. In a screen, a framecomposed of tubular side and end pieces mitered-at the cor ners, said tubular side pieces having lengthwise grooves inturned in the outer edge, an internal brace consisting of triangular sheet metal plates connected for a portion of one side to provide triangular ends to fit within the tubular frame ends each side of the sheet metal sides of said lengthwise grooves, said tubular frame sides soldered to said internal brace at said mitered joint.
