a cum.

This invention .relates to screens for windows, doors, and other openings, and aims to provide certain improvements therein. The invention is particularly directed to so as to resist particularly from 5 is designed to provide unusual structural to a high degree strains or blows the inside of the room in which a screen of the type which strength it is used, and preferably from both the inside and outside. An important function of the screen provided by the invention fly" screen, namely, that of excluding is that of the ordinary insects and to some extent dust and other matter. In the use of the ordinary insect screens in hospitals, insane asylums, or the like, it has been found necessary to use some additional protection to prevent patients from escaping through windows,

doors, or the like, especially when the patients are deranged either temporarily or permanently.

The ordinary window screening has insufiicient strength for this purpose and the additional protection usually takes the form of bars or very heavy'wiring. Such means, however, are found in many cases to have a disadvantageous effect upon the patients, being suggestive that the patient is a prisoner or held under restraint. The

principal object of the present invention is to provide a screen which has approximately the same appearance as an ordinary window screen but which is of such strong patient can apply to it by of a chair or other piece of any force which the his body or by the use furniture.

The invention construction as to resist will be described with reference to the accompanying drawing which illustrates one form of the invention.

Figure 1 is a perspective view, partly in section,

of a corner of a screen provided by the invention.

Fig. 2 is a sectional perspective showing the several parts separated, the lining members being shown in their original condition, that is, before the parts have been clamped.

Fig. 3 is an enlarged sectional perspective of one of the lining members,

showing the indentations thereon formed by the screen cloth.

In constructing a screen according to the present invention there is cloth of much greater a necessity for a screen strength than those which are commonly employed. This screen cloth may be made out of steel,

bronze, brass, aluminum alloy, or nickel alloy, or othersuitable metal, but it is preferable to use a metal in which the individual wires shall exhibit sufllcientstrength with small enough diameter to avoid cutting down the mesh openings any more than is necessary, both from the standpoint of admission of light and air and that of simulating the ordinary screen. The dimensions of the wire and openings should be kept as near to common screens as possible. The fastening of the wire screen cloth in the opening is the principal feature of the invention. Ordinarily a frame will be used to which the screen cloth is attached, and the material of the frame and its method of fastening in the window or other opening will be selected to give the necessary strength. In the practice of my invention I use a heavy metal frame, and provide means for fastening the screen cloth to such frame in a way that produces an extremely strong connection in which the wire cloth will not part from the frame under extreme strains.

In the drawing I have shown the frame A as formed of solid metal, such as steel or bronze or extruded aluminum or one of its alloys. To secure the desired strength of frame, it is necessary that themetal which composes it shall be hard and durable.

According to the preferred form of the invention the frame comprises a body member B and a clamping member C. Between these the screen cloth or wire D is confined. The clamping member C is secured to the body member in any suitable fashion, as for instance by the screws E, E. In the preferred form of the device the body member and clamp member are interlocked by forming a groove in one and a flange or tongue in the other. The most appropriate member in which to form the groove is the member B, and the drawing shows it formed in this member as indicated at the letter F. The corresponding tongue on the clamp member is lettered G. It will be seen that when the screws E are tightened the clamp member C cannot be pulled inwardly in a lateral direction away from the body B because of the engagement of the tongue G with the wall H of the groove F. Conversely, the body member 13 cannot be pulled inwardly in a lateral direction away from the clamp C because of the engagement of the tongue G and the outer edge of the clamp with the wall I of the body member. Hence the principal if not the entire function of the screws E is to hold the two parts together, all the strains being taken by the interlocking groove and tongue. Furthermore, the screen cloth is of suillcient size to pass beneath the tongue G and be bent by it at an angle as shown. This bend of all the lateral strands of the screen cloth tends to promote an excellent clamping action between the two parts.

However, according to the present invention the main clamping action is secured by one or two strips of material J, K arranged between the clamp and the body, this material being of sumcient softness to become indented or imprinted with the screen cloth so that the latter becomes to a greater or less extent actually sunk or embedded in the opposing faces of the two strips. Various materials may be used for this purpose, but I have found a soft metal such as lead to have a superior action. The strip should have a considerable width so as to engage a plurality of longitudinal strands of the screen cloth as well as the ends of the entire series of lateral strands.

In order to prevent the strips from pulling out of the body portion and clamp C, each of the latter is formed with a flange L against which a portion of the strip abuts. Preferably this flange in each case is formed by recessing the opposing members as shown at M. Preferably also the inner edges of the strips extend so that they overlie the flanges as shown at O and terminate at the inner walls of the body and clamp. This insures that the screen cloth shall not come in contact at the inner edges of the screen with the hard metal or other material with which the body portion and clamp are constructed.

One of such strips is shown .detached on a larger scale in Fig. 3, the indentations therein illustrated having been previously made by clamping the screen cloth in place.

By the construction as hereinbefore described the body portion and the clamp are practically inseparable by any blow upon the screen cloth, and the screen cloth is held in place in such manner that it is not subject to any cutting or breaking action at the points of connection. The grip of the lead or other strips upon the screen cloth is sufliciently soft to avoid any unusual pressure on the strands of the cloth, and sufliciently hard to prevent the cloth from pulling out under very extreme conditions. The preference which I have expressed for lead as the material of which the strips are composed does not exclude the use of other materials, and other changes may be made in the construction described without departing from the invention.

It is obvious that the invention is applicable to window screens, door screens, and screens for other openings. I have shown and described the invention as applied to the conventional frame, but it will be noted that the frame may comprise a fixed part of the window or other opening and the appended claims are to be read with this in view.

What I claim is:

1. A screen for windows or the like comprising a frame and a screen cloth, the frame comprising a body portion and a clamp portion between which the screen cloth is conflned, and the body portion being faced with material of sufllcient softness to substantially embed the screen cloth when the body and clamp are connected together.

2. A screen for windows or the like comprising a frame and a screen cloth, the frame comprising a body portion and a clamp portion between which the screen cloth is confined, and the clamp portion being faced with material of suillcient softness to substantially embed the screen cloth when the body and clamp are connected together.

3. A screen for windows or the like comprising a frame and a screen cloth, the frame comprising a body portion and a clamp portion between which the screen cloth is confined, and the body portion and clamp portion each being faced with material of suflicient softness to substantially embed the screen cloth when the body and clamp are connected together.

4. A screen for windows or the like comprising a frame and a screen cloth, the frame having a body portion and a clamp, and each of said parts having a strip of relatively soft material adapted to engage the screen cloth, and each of said parts having a flange to hold said strips in place.

5. A screen for windows or the like comprising a frame and a screen cloth, the frame having a body portion having a groove, and a clamp having a tongue entering said groove, the opposing faces of said body portion and clamp being recessed, and a lead strip in each of said recesses, together with means for connecting the clamp and body portion with the screen cloth between them.

6. A screen for windows or the like comprising a frame and a screen cloth, the frame being in two parts and adapted to clamp the screen cloth between them, and a lining material between the inner edges of each of said parts interposed between them and the screen cloth, whereby the screen cloth is held out of contact with both said parts of the frame.

7. A screen for windows or the like comprising a metallic frame having a body portion and a clamp portion, opposing faces thereof being recessed, a lead strip in each of said recesses, said strip extending to the inner edges of the body portion and clamp, and the screen cloth being confined between said lead strips whereby the screen cloth is clamped between said strips and is held out of contact with the clamp portion and the body portion at the inner edges of the frame.

8. A screen for windows or the like comprising a metallic frame having a body portion and a clamp portion, opposing faces thereof being recessed, a lead strip in each of said recesses, said strip extending to the inner edges of the body portion and clamp, and the screen cloth being confined between said lead strips whereby the screen cloth is clamped between said strips and is held out of contact with the clamp portion and the body portion at the inner edges of the frame, and said body portion and clamp portion having a tongue and groove connection lying laterally outside of said strips.
