ROLLING SHUTTER.

Specification of Letters Patent.

Patented. Nov. 20, 1906.

Application filed A ia 7, 1906. Serial No. 310.524.

To all whom it may concern.-

Be it known that 1, JAMES G. WILSON, a subject of the King of Great Britain, and a resident of Larchmont, Westche'ster county, and State of New York, have invented certain new and useful Improvements in Rolling Shutters, of which the following is a specification.

My invention relates to means for permitting light to pass through such shutters, and is intended to be applied more particularly to the shutter patented to me in United States Letters Patent No. 405,450, June 18, 1889, although I do not limit myself to the application of my invention to the device there shown.

In the drawings, Figure 1 is a front view of the structure embodying my invention, parts being broken away. Fig. 2 is a vertical section on the line 2 2 of Fig. 1, and Fig. 3 is a horizontal section on line 3 3 of Fig. 1.

In the drawings, a a are a series of slats of wood or other suitable material threaded upon a number of metallic bands A, distributed at proper intervals throughout the width of the structure, the slats being provided with suitable interlocking tongues and to hold the same parallel with each other and to give strength and stiffness to the structure. The lower ends of the metallic bands are attached to coiled springs B, located in recesses in the lower slat O and attached to said slat by means of screw D, nut d, and metal plate e. The general construction and operation of the device is that shown in my earlier patent, above referred to and need therefore not be more fully described here.

In order to permit light to pass through the rolling shutter, I insert between one or more pairs of slats 0, strips of translucent material-such as mica, glass, wire-netting, or glass or other like material reinforced by wire-netting. As shown in the lower part of Figs. 1 and 2, one of the slats a is provided with a groove or kerf n, corresponding to a m in the slat 0 located above the same. Into these grooves or kerfs I slip a strip of translucent material on in such a manner that the same is held in these grooves or kerfs.

In order to prevent the crushing of the strips 20 by the pressure of the slats, I provide distenders y 2, preferably made of metal, slipped into the grooves or kerfs and placed in front and rear, respectively, of the metallic These distenders serve to keep the slats a and a at a proper distance from one another. As no light passes through the metallic bands A, the distenders are preferably placed in front and in rear of these bands, as in any other locality they would prevent the passage of some light-rays through the shutter.

At the upper portion of Figs. 1 and 2 and also in Fig. 3'1 have shown another form of my invention. In this form the slats 1 and 2 are provided with central grooves or kerfs 3, running lengthwise of said slats, and are prevented from being drawn together by the springs B by means of short sections of slats 4. These short sections 4 are preferably at points where the metallic bands A will pass through them, said sections 4 being slotted, as at 5, for this purpose. are thus prevented from moving lengthwise of the slats 1 and 2 and serve as distenders in the same manner as the distenders y and z, hereinbefore described. The sections 4 are also provided with grooves or kerfs 6, running transversely of the grooves 3 in the slats 1 and 2. In this form of my invention the translucent material 7 is introduced in sections, each section being located between two short slat-sections 4, the four edges of said sections of translucent material 7 being received in the grooves 3 of the slats 1 and 2 and the grooves 6 of the slat-sections 4. The translucent material 7 is thus held securely in position in the same manner as a pane of glass in a window and is prevented from being crushed by the pressure of the adjacent slats by the short slat-sections 4.

Of course the form and construction of the distenders, as well as of the translucent strip, may be widely varied without departing from the spirit of my invention. Nor do I limit myself to the use.of this invention in roller-shutters, it being applicable to many other structures, such as partitions and linds. Cables or wires may be substituted for the bands.

I/Vhat I claim as new, and desire to secure by Letters Patent, is

1. In a rolling shutter a series of slats threaded on metallic bands, in which. two adjacent slats hold between them a strip of translucent material.

2. In a rolling shutter a series of slats threaded on metallic bands, a strip of translucent material held between several of such translucent strips :11.

bands A at the points where they cross the These sections 4 IIO slats, and means for holding said slats separated in order to prevent a crushing of the translucent strip.

3. In a rolling shutter a series of slats threaded on metallic bands and strips" of translucent material held between such slats in grooves provided in the adjacent sides of such slats.

4. In a rolling shutter a series of slats threaded on metallic bands, a strip of translucent material held between a pair of such slats in grooves provided in the adjacent sides of such slats, and one or more distenders located in said groove to prevent a crush ing of the translucent strip.

5. In a rolling shutter, a series of slats threaded on metallic bands, and one or more distenders holding apart the members of a pair of slats, the aggregate width of such distenders being less than the length of the slats, so that light may pass between the slats, substantially as described.

6. In a rolling shutter, a series of slats threaded on metallic bands, one or more distenders holding apart the members of a pair of slats, and strips of translucent material for closing the opening between said slats.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
