5 Claims.

The subject matter of my present invention relates to the screening of swinging sash as generally typified by the ventilator structures in a metallic sash. I

The problem of installing such screening involves a variety of difliculties that are both structural as to the screening equipment and mechanical in the basis of installation. Previous systems have usually involved a considerable amount of mechanical work on the ventilator or its enclosing sash or other parts of the installation. In practice the necessary drilling and tapping of the metal frames involved labor that was almost prohibitive in the installation cost.

One or" the objects of my present invention is to make possible such installations with a minimum of drilling and tapping and with a maximum of eificiency and adaptability.

As illustrative of my invention I have shown an embodiment which may be taken as characteristic. In this I have shown certain parts which have become more or less standard and as such I deem it advisable to employ them, although I do not wish to be limited to such detail.

In such parts as I have devised in departure from standard practices, I have endeavored todevelop my concept of an installation which would be of the highest efiiciency and yet such as can be installed quickly and at low cost. Notably, I have solved the problem of screen channels by providing strips which can be applied without drilling and tapping and which in accordance with my invention may be made selfsustaining in an interlocked relation so that the old original system may be applied in a fraction of the time heretofore involved.

Throughout the specification and drawings like reference characters are employed to indicate corresponding parts, and in these drawings:

Fig. 8 a similar view with the ventilator partly open.

Fig. 9 an illustrative view of screen lodgement, and

Fig. 10 a filler detail on the screen itself.

In Fig. l I have illustrated a characteristic ventilator installation in a usual type of metal sash as illustrative of the general problem, although my invention may be said to relate particularly to the problem involved in the ventilator V and its surrounding sash S which de fines the aperture the ventilator controls, and to the side members of which it is pivoted as at P.

In such a construction the ventilator tips from its vertical or closed position to a horizontal or fully open position at central or other levels according to different type of construction. All these must be provided for. The problem of screening such a ventilator involves factors of accommodation for the several dimensions of the ventilator and its surrounding frame in their various relative positions which vary according to the angle of swing of the ventilator. The greatest problem, however, has been that of providing a basis of quick installation for the channelguides of the screen.

In considering the ventilator, it is necessary to regard it as having an upper and lower area as regards its pivot, wherever located, about which it turns. The pivot P is usually located on the inside of the ventilator in its frame so that the ventilator does not turn on its central vertical plane, but on the pivot which lies in the plane just inside its inner edge.

In accordance with my invention I provide for screening on the basis of an inner or lower screen H to the full height of the pivot center and an outer screen or upper screen A terminating above the center of the pivot a distance to accommodate the thickness of the ventilator V and provide for a filler system which will maintain closure between the fixed and moving parts as the ventilator is moved and in whatever position it may be left. This has been attempted but has necessitated channel supports for the screen edge which had to be attached to the frame members by many drillings and tappings which involved hours of labor and corresponding incident expense.

In the embodiment shown I provide a base B for the upper screen which consists of a bracketshaped strip adapted to support the lower edge of the screen A and which is fastened as at B to the side sash S. It is to be noted that these are the only fastenings requiring both drilling and tapping.

At the end of the base B I provide a filler E best shown in Fig. 6. This is located at the end of the base B and is held by the fastening B previously described. Adjacent this filler E disposed vertically in the line of juncture of the ventilator side and the adjacent sash is a pivot cover D carried at the end of the member C which makes the screen tight on its sides with the adjacent sash frame S. These factors are known and have been recognized, but the most diflicult problem has persisted in the screen channel which so far has been applied to the metal sash by laborious drilling and tappings which has taken many hours of labor for a single ventilator installation. My principal effort has been to eliminate this difficulty without disturbing the general basis of engineering these equipments.

At the top of the screen A is a channelled member G which is preferably formed of slightly resilient sheet metal stock and is characteristic of my invention. It is reversely channelled as at g so as to engage the flange s of the sash S. In putting on the screen A it is pushed up under the channel G which is of sufficient depth to allow the lower edge of the screen to clear the retaining edge of the base B as indicated in Fig. 9, which illustrates one of many embodiments of my concept.

These guide strips can be produced very cheaply and yet are capable of being attached to the various sash flanges of different installations with little or no variation. They provide a channel guide or grip for the screen and by the reverse bend engage and hold any of the necessary flanges common to different manufacturers of metal sash. In the combination they become interlocked and inter-sustained so that they knit the old basis of installation into a system in which the previous basis of drilling and tapping become unnecessary as a whole and merely an insignificant incident in an expeditious operation.

Referring now to the installation of the inner or lower screen H, I provide in accordance with my invention such a bottom piece J of the same general cross section as the member G so that its flange 7' will slip over the upstanding sash flange .9 which is on the inner side of the bottom of the ventilator opening. The sides of the lower screen are held in place by side pieces K similar in cross section to J and G and which slip on to the inner side flanges s as in the manner above described. It will be noted that when the screen is in place the channels J and K are thereby interlocked against any possible displacement.

The screen H is held at the top by a cap member L which comprises a metal strip bent on itself so as to have a filler piece Z with an outwardly disposed angular portion so disposed with relation to the pivot P that when the sash is closed it will bear directly on the top of the screen 1-1. It is supported by a bracket Z at each end held by screws and wing nut fastener Z so as to be quickly detachable. This requires a mere drilling of the outwardly disposed lateral flange d of the ventilator and makes the cap member L readily removable when the screens are to be taken off or put on. The member L and its filling piece Z takes care of the ventilator depth or space between the glass X and the inner face of the ventilator frame.

To provide for the corresponding but varying differential between the other side of the glass and the base B, I provide a member C. This member is a strip having an end 0 bent at an angle adapted to ride on the outer surface of the glass X. Its lower edge rests in a trough 1) formed on the bottom of the base B. These members are loosely tied together by rings 0 I provide an additional filler F for the sides of the upper screen, this piece being an angular strip secured to the screen A as by screws ,1. These work in lateral slots in the filler F, the screws being self-tapping screws to facilitate installation. These pieces when in place also prevent any possible dislodgement of the outside screen A thus insuring against those not infrequent accidents due to the falling of outside screens on people below.

The holes in the screen frame A are also in practice drilled by the manufacturer. The free edge of the filler F bears against the inner edge of the outside lateral frame members of the ventilator V when the ventilator is in closed position, as indicated in Fig. 7. From the foregoing it will be seen that my screen equipment can be installed with an absolute minimum of labor and yet when installed afford the basis of an absolutely complete sealing of the ventilator in any position of its swing. Furthermore, the screens may be removed or replaced with the greatest ease.

While I have described and illustrated the foregoing installation as an embodiment of my invention in considerable detail, as representing a simple and highly effective basis of installation at reasonable cost, I do not wish to be limited thereby but to have my invention considered on the basis of my concept as more broadly formulated in my claims. 7

What I therefore claim and desire to secure by Letters Patent is:

1. A retaining member for use with a flanged sash member and a screen, comprising a folded sheet metal strip of resilient metal having a fold 115 presenting a screen guide and a reverse fold presenting a flange clamping member.

2. A screen guide comprising a resilient strip having a folded channel comprising the edge receiving member and a reversely bent portion constituting a flange engaging member adapted to receive the weather flange of a metal window casing.

3. A retaining member for use with a flanged sash member and a screen, comprising a doublechanneled guide having offset channels one channel engageable with said screen and the other channel engageable with the sash flange so as to interlock the screen and sash.

4. A retaining member for use with a flanged 130 sash member and a screen comprising a strip having offset and oppositely disposed channels engaging the sash flange with one channel and the screen edge with the other channel.

5. A retaining member for use with a flanged 135 sash member and its screen, comprising a strip of sheet material having a fold providing a continuously extending guide channel into which a screen is adapted to be slid and frictionally retained, said strip having a reverse fold pro- 140 viding an opposing continuously extending channel adapted to receive and frictionally clamp the flange of the sash member.
