The 'main piece 20 hasra ledgedgroove 2l into Vwhich thezedge-,of'the screen cloth I8V is received, the construction being. suchV that the screen cloth is 'stretched` .over arr: outside lip'ZZ andthe edges Il forcedginto thegroove 2|.- The small lpiece or fill'eti I8; having surfaces: which-.are

I show in Figure '7 a sash or frame 28 having a ledge portion 29 the upper surface of which engages the lower edge oi a panel 30 which may be glass, metal, plastic, wood, screen cloth or other desired material. The upper edge of the panel is engaged by a fillet or strip 3l of thermoplastic material vone edge of which engages the sash. The fillet 3| is then heated and pressed into engagement with the sash and fused thereto to form an integral sash which grips the edge of the panel 30.

In Figure 8, the sash comprises a lower portion 32 and a cooperating upper portion 33 having beveled mating surfaces 34 and an edge groove 35, in which the edge of panel 36 is received.

The construction shown in Figure 9,is similar to that described and shown in Figure 8 except that the mating surfaces of the pieces 31 and 38 are not beveled. So also the construction illustrated in Figure 10 is similar to the construction shown in Figure 9, except the pieces 39 and 40 have a T-shaped groove 4I when assembled. In this groove a readily deformable filling material can be placed to seal the edge of the panel 42.

A suitableV material for the filler is ordinary putty, n

union of the parts is effected by a chemical fusion producedby the solvent, and it may further be noted `that the term welding applies not only to the union effected-through the use of solvent, but also to the union effected by the use of heat.

In Figure 11, I have shown a cross section of a desirable corner construction'for joining the side member or stile Il and the end member or rail ,|12V of a frame. The ends of each are reduced `in cross section and a metal reinforcing plate 43 having holes 44 therein is placed between the mating surfacesY at. the corner. Sufficient thermoplastic stock is provided so that when the ends are fused together by pressure and heat the surfaces and edges will all be flush. 'I'his operation can be performed at the. same time that the screen or panel is being fused into position in the sash.V

A frame orvsash, made according to my invention. tightly-and permanently grips the Vassociated panel and provides weather-tight joints and a structure having a long life, permanently colored. and of pleasing appearance. The frame can be cheaply and quickly made, and there is no possibility of any portion working loose.

While I have described certain exemplary embodiments of my invention, it is to be understood that various changes in the arrangement and shape of the frame and the methods of making it may be made within the scope of my claims.

I claim:

1. A structure of the class described comprising a panel of screen cloth having its edges ofiset from the plane of the panel body, and a surrounding rigid one-piece frame of organic fused and shaped thermoplastic material embedding and rigidly solidified upon such edges of the screen cloth and filling the interstices in the embedded edges.

2. A structure of the class described comprising a panel of wire screen and an integral rigid one-piece supporting frame of thermoplastic organic materiahsaid frame having a ledge portion, said ledge being fused and rigidly solidified 1 upon and embedding the edges of the wire screen.

3. In a window comprising a panel and a surrounding frame, a rigid one-piece frame made from sections of thermoplastic organic material fused and rigidly united to form an edge groove in which thepanel is marginally received and a sealing groove forming an extension of the edge groove and enclosing a seal in contact with the rim of the panel.

4. .A structure of the class described comprising a panel of wire'screen and an integral supporting frame having a perpherally extending l'edged groove in Vwhich and over the ledge of which the edges` of the wire screen lie, said framebeing formed of thermoplastic material fused and rigidly solidified upon said edges of the screen and within the interstices therein.

5. A structure of the class described compris- `ing a panel ofv Wire screen and van integral supporting frame having a peripherally extending ledged groove in which and over vthe ledgeof which the edges lof, the Wire screen lie, said frame being formed of thermoplastic material fusedand 'rigidly solidified upon said edges of the screen and within the interstices therein, the plane of the panel being approximately coincident with the plane of one of the faces of the frame body.

6. A structure of the class described comprising a frame having a side member and an end member formed of plastic material, and a corner reinforcing element formed of av different material, said members being at a corner of the frame, fused and rigidly united, .with said reinforcing 'element embedded in and integrated. with the rate corner reinforcing element formed of metal, said members being at a corner of the frame.

fused and rigidly united with each other and with said perforate reinforcing element, the fused and solidified plastic material filling the perforations in the reinforcing element.

`8. A structure of the class described comprising a paneland a surrounding integral' frame formed of a plastic material fused upon the edges of the panel and rigidly solidified, with said edges embedded inthe plastic material of the frame. said frame having a side member, an end member, and a perforate corner'reinforcing element, said members being at alcorner vof the frame. fused and rigidly united with each other and with said perforate reinforcing element, theY fused and solidified plastic material filling the perforaticns in the reinforcing element.
