3 Claims.

` `This invention relates toVenetian blinds and the method of manufacturing the same, the object being to provide a construction presenting a Venetian blind structure of Substantially the usual type but with a special shutter.`

Another object of the invention isto provide a shutterforVenetian blinds wherein acovering of cloth, paper, or the like is, provided, and positioned on the base so as to present a substantially integral appearing article.

In ythe accompanying drawings:

Fig.` 1 is an elevation of a Venetian blind constructed according to the present invention;

Fig. 2 is a plan view of one of the complete'.

shutters shown in Fig. l; Fig. 3 is a perspective view on an enlarged scale of the shutter shown in Fig. 2;

Fig. 4 is a diagram partly in section illustrating part of the method of applying a covering to a shutter base; Y

Fig. 5 ls a side view illustrating how the wrapped shutter base is passed through squeezing rollers;

Fig. 6 is a plan view with certain parts broken away of the finished shutter before the ends have been cut or trimmed;

Fig. 7A is an enlarged fragmentary sectional view through Fig. `2 approximately on the line 1 -1.

Referring to the accompanying drawings by numerals, I indicates a head piece of the shutter structure 2. Carried by the head piece I are a number of shutters or slats 3 together with actuating cables 4 and supporting straps or bands 5. Each of the shutters 3 is formed with a base i which may be of Wood, paper, fiber, or other material. However, most of the shutters are made from Wood because they are light and yet sumciently strong to perform `the desired result. Heretofore shutters formed of wood or other material have been coated with paint or other color- 40 ing matter to present a certain design effect.

However, by thisl method flowers and other configurations could not be provided, exceptJ at very great expense.

Asshown inFig. 3, the base 6 is covered with a y textile fabric covering 1 which is overlapped at 8 adjacent one of the longitudinal edges of base B. The covering l, while preferably of fabric, may be made from paper or other flexible material, and consequently when the` expression textile fabric is used it will be understood that these other elements are equivalent. l

In Figs. 4 to 6 diagrams have been presented illustrating the method of manufacturing or producing the complete shutter as shown in Fig. 3. As illustrated in Fig. 4, there is provided a supply (ci. s- 11) I 9 of fabric which is preferably slightly wider than the base 3 is long. This fabric is passed beneath an adhesive applying roller I0 which receives adhesive from the container I I and applies the same to one surface of the fabric 8'. After Ythe fabric passes the adhesive applying roller Ill it moves on to a table I2 and when a desired length or section is on the table I2 the knife I3 functions to sever the fabric. The severing section is then moved forwardly a short distance and a base 3 applied thereto near one edge. The edge I4 is then turned over and then the base, edge I4, and adjacent portions are turned over as illustrated at the extreme right in Fig. 4. This will cause the edge portion I5 to overlap the edge or end portion Il. The work on table I2 is done by hand, and after the base 8 has been completely wrapped, as just described, it is placed on a table I6 and then fed between squeezing rollers I1 and I8 which press the coated fabric tightly against the base and also press the overlapped edges I together. Rollers Il and I8 are preferably formed of rubber or other resilient material. After the wrapped base has passed the squeezing rollers I1 and I 8, it is set aside until the adhesive has completely dried. The unnished shutter is then taken to a suitable machine for cutting the cable slots I9 and 20. It Will. be noted that the cutter, in forming the slots I9 and 20, cuts through the fabric as well as the base 6. After this has been done the ends are trimmed off so that the finished shutter, as shown in Fig. 2, will be of the desired length. Preferably the ends are cut off by a suitable saw along the respective lines 2i and 22.`

As illustrated particularly in Fig. 7, each of the shutters 3 is provided' with a metal cap 23 at each end. This cap may be of the same color as the covering fabric or paper or of a different color, as for instance chromium or silver plated metal. The use of the caps 23 is importantin that it not only presents a pleasing appearance but it finishes the, ends of the shutters. In cutting the ends along the lines 2i and 22 as` shown in Fig. 6 it sometimes occurs that the cutting is more or less irregular and therefore would be objectionable if left uncovered. The caps 23 not only cover the irregular end formation butV are squeezed to pinchthe shutter and thereby stiifen and strengthen the same. In addition, the apertures I9 and 20 are provided with slots I3 and 2li' extending to the edge of the shutter. A hollow rivet or eyelet 24 is arranged in each of the slots I3 and 2li. These eyelets have extensions 25 and 2i that protect the edges of the radiating slots I8 and 2li'. It

the slot.

`come broken at some point intermediate the ends is to be noted that the members 25 and 26 extend only to the edge of the shutter but not across the edge. -One end of the rivet or eyelet 24 vis completed usually before it is applied Vto the shutter and then the other end is bent over as 4illustrated in Figs. 2 and rI so as to grip the shuti ter and not only protect the raw edges around the slots but act as reinforcing means for the slots. The slots I9 and 20' are desirable inV that they will permit a shutter to be completely applied and removed bypulling the cable through For instance, if a shutter should be- YIn this way the shutters are properly held in position until positively moved to a disengaged position.' i

I claim:

1. A Venetian blind including a plurality of slats, each slat comprising a solid base, a onepiece complete coveringoffiexible materialintimately engaging said base and extending `from Also one end of the base to the other and entirely around the base with the edges of the covering overlapping near one longitudinal edge of the base, adhesive for securing said covering to said base, and a metal protecting cap for each end o! the slat, said caps covering and pinching the end portions of said covering tightly against the base.

2. A Venetian blind including a plurality of slats, each slat comprising a solid base, a coating of adhesive and a one-piece complete covering of textile fabric held on said base by said adhesive, said textile covering extending from one end of -said base to the other and entirely around the base with the edges overlapped near one longitudinal edge of the base.

3. A Venetian blind slat comprising a base solid throughout, a iiexible covering for said base secured to the base in intimate contact therewith,

said flexible covering extending from one end oi' said base to the other end and entirely around the base with the edges overlapped near one longitudinal edge of the base, said base having cord receiving slots merging into radiating slots extending tothe edge of the slat, metal eyelets lining all of said slots, the edges of said eyelets pinching said covering to said base, and a metal cap for each end Yof the slat, said metal caps pinching the end portions of the covering and slat.
