SCREEN.

Application filed February 7, 1908.

To all whom it may concern:

Be it known that I, HENRY JAY SHARP, a citizen of the United States, residing at C0- lumbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Screens, of which the following is a specification.

My invention relates to screens of that class which are adapted for use as fly screens for windows, doors, etc., and the objects of my invention are to provide an improved screen of this class of superior construction and arrangement of parts; to so construct the same as to admit of the screen and its frame being readily separated and of the substitution of a new screen should the same be required; to so construct my improved screen frame as to admit of the screen wire being bound therein without injury to the screen and to produce other improvements the details of construction and arrangement of parts of which will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which:

Figure 1 is a face view of one of my improved window screens, showing one of the corner caps removed for the sake of clearness in illustration, Fig. 2 is an enlarged detail section on line wm of Fig. 1, Fig. 8 is a plan view of the corner portion of the lower section or member of the screen frame, and, Fig. d is an enlarged sectional view on line 3 3 of Fig. 1 looking in the direction indicated by the arrow.

Similar numerals refer to similar parts throughout the several views.

In the construction of the side and end members of the screen frame, I employ inner and outer metallic strips or sections and an intermediate section or filling piece of wood. The inner metallic section which is indicated at 1, is, as shown, in the nature of a channel bar having the outer portion of its sides flanged inward as indicated at 1*. WVithin this channel section 1, I employ a filling strip 2 of wood, said wooden strip having the central portion of its upper side raised above the section 1 and said raised portion having formed centrally and longitudinally therein a groove or recess 4:.

5 represents the outer metallic section or frame member, the central portion of which is of the convex form shown in the drawing and the edge portions of which are bent or Specification of Letters Patent.

flanged outwardly as indicated at 6 and 6. At the center of its width the section 5 is, as shown more clearly in Fig. 2 of the drawing, bent inward to form a central inwardly projecting tongue 7.

The ends of the metallic and wood sections or strips of the frame are properly beveled or mitered for the purpose of forming the proper miter joint of the frame corners. In uniting the end and side sections 1 1, I provide an angular channel plate such as is lndicated at 8, said channel plate being in the nature of a corner reinforcing piece or plate which is brazed or otherwise secured within the ends of two adjoining sections 1 and which covers the miter joint of said sections and serves to firmly unite the sections at the corner.

9 represents the screen body which is in the nature of a sheet of wire cloth, this screen body being secured in connection with the frame in the following manner: The marginal portions of the screen are arranged to extend over the upper side of the wood fillers 2, after which the upper metallic section 5 is pressed into its position above the wooden strips, the tongues 7 of said upper sections 5, together with a proportionate amount of the screen material being made to enter the socket 4 of the flller. In thus placing the outer metallic section, its outer flange 6 is made to engage the underside of the outer inturned flange 1 of the section 1, while the flange 6 of said outer section 5 bears upon the screen body above the inner flange 1. The screen by these means having been properly stretched in its position upon the frame, small nails which are indicated at 10 are driven at desirable intervals through the flange 6 thence through the screen and the inner flange l and into and through the inner portion of the wood filler. As shown in Fig. 2 of the drawing, the contact of the point of the nail with the inner surface of the metallic section 1, will result in said point being turned or clenched out ward into the wood filler, thus insuring a desirable engagement with the latter.

In completing the screen and frame therefor, I employ corner cap pieces 11 which are in the nature of angular channel pieces stamped in such shape as to embrace the face of the frame at the corners thereof. These corner caps are held in their proper positions through the medium of bolts 12 lic frame sections and which carry ontheir.

outer ends nuts 13 which may be suitably ornament ed as desired.

It will be observed that in the construction of my improved screen frame, the wire cloth is pressed by the outer metallic section into engagement with strips of wood and owing to the yielding nature of the wood, it is obvious that the tendency of destroying the galvanizing or otherwise working injury to the wire which arises where screen wire is bound between two pieces of metal, is obviated. It is also evident that the yielding nature of the Wood will offer a more effective screen binding agent than metal, thus insuring a more complete locking together of the frame and screen.

, While my improved frame is intended to exclude moisture, it will be understood that any water which might by accident or otherwise be permitted to seep between the two metallic sections, will not be permitted to accumulate therein until the metal parts are injured by rust, but that the slight amount of water which might thus enter the frame, will be absorbed by the wood filler. The construction of my improved screen frame is such as to permit any person of ordinary intelligence to remove the screen body from the frame for the purpose of substituting a new one, this being readily accomplished by first removing the caps 11, withdrawing the nails and the outer sections 5, permitting the screen to be readily detached from the frame. It will also be observed that the construction of my improved screen and its frame is such as to admit of the metallic frame comprising an inner metallic member,

an outer metallic member having a project- 1ng tongue portion, a wooden filling strip between said metal members, said wood filler having a groove adapted to receive the tongue of said outer metal member, and said wood filler being inclosed between said metallic members, of a screen body having its marginal portion embraced between the outer metallic member and the wood filler.

2. in a screen, the combination with a frame comprising detachably connected metal sections and an intermediate wooden section, one of said metal sections having a projecting tongue and said wood section having a groove, of a wire screen body having its marginal portions embraced between one of said metal sections and the wood section.

3-. In a screen, the combination with an inner and outer frame member, one of said members having a tongue projection, and an intermediate member having a recess therein adapted to receive said tongue, of a screen body having its marginal portions bound between said tongued and recessed members.

In testimony whereof I aflixrmy signature in presence of two witnesses.
