MACHINE FOR CREASING FLUTED FABRICS.

SPECIFICATION forming part of Reissued Letters Patent No. 9,071, dated February 10, 1880.

Original No. 171,264, dated-December 2l,

To all whom t may concern:

Beit known that I, J OHNE. BROWN, of New York city, New York, have invented certain new and useful Improvements in Machines for Pressing or Oreasing Flutings, which im provements are fully set forth in the following specification, reference being had to the accompanying drawings.

In the method heretofore practiced for pressing or creasing flutings a narrow metallic edge is brought down upon the fluted fabric and there pressed until a crease is formed, which monly called a gum-cordl-that is, a cord or thread moistened with some adhesive substance. This method is slow, because thefluted fabric has to bc moved along, space by space, under the pressing-iron as the operation is performed on each section of the length of the uted fabric, and it is also defective because the ute which is crushed down will sometimes fall forward and sometimes backward, producing an irregular appearance in the goods. My machine greatly facilitates the operation, and at the same time produces a much more perfect result.

The characteristic features of my machine are a supporting-surface, over which the flutings are fed, combined with an endless rotating pressingsurface converging very gradually to the plane of the supporting-surface.

In the accompanying drawings, Figure l is a plan of my machine. Fig. 2 is a section in elevation at the line yy, showing also the gearing in elevation. Fig. 3is asection at the line ac x, Fig. 1.

- The same letters refer to similar the drawings.

C is a hollow cylinder revolving upon-an axis supported bya bearing in the frame of the machine. In the interior of this cylinder heat may be applied, either by a gas-jet or other appropriate means. A is a presser feeding-roller, having a cylindrical surface at h. The other portions are beveled o' to permit portions of the uted fabric to pass without being pressed. (See Figs. 1 and 2.) This roller may be made hollow, and may be heated by a gas-jet or other appropriate means. This roller is mounted upon arevolving shaft, which is driven by a parts invall 4gear-wheel, a, from a correspon din g gear-Wheel,

is usually retained in place by what is com- 1875. Application for Reissue filed December 10` 1879.

c, on the shaft of the cylinder C. The shaft f the rollerA is supported upon a lever, g,which vibrates around a center, g4, so placed as to permit a slight nearly vertical movement to the roller A. Through this lever a set-screw, g', passes, having a recoil-spring, g3, between its head and the topl of the lever, and being screwed into the frame of the machine at f.

By turning down this set-screw this roller A will be pressed upon the cylinder O with greater force, and the spring will permit it to yield and rise slightly, as occasion may require.

D and B are two band-Wheels mounted upon two centers, k' and k2. The object of these wheels is to cause the pressing-surface or band which they carry, and which is carried also by the pressing-rollers, to converge to the supporting-surface more gradually than it would if the presser-roller alone acted as such surface, unless such roller was of very large diameter.v These two centers are fixed upon a vibrating beam, which is centered at K upon the lever L, which is centered also on the frame of the machine at L. The upper end of this leveris provided with a screw, l, whose office is to tighten or loosen the bands which pass over the band-wheels by moving the lever L away from or toward the cylinder and presser-roller, as required. When this set-screw is tightened the beam which supports the two wheels B and D accommodates itself to the length of the bands and assumes the position which will make the tension equal upon both bands.

i i and hh are narrow bands which form the pressingsurfaces, preferably of metal. The band h h passes around the wheel B and the presser-roller A, and acts to gradually flatten and crease the uted fabric between its surface and that of the band M, which passes around the wheel D and the cylinder O, and acts to support the fabric against the pressure of the other band. `The centers of the bandwheels B and D are farther apart than the centers of the cylinder C and presser-roller A, so that the bands converge as4 they approach the pressure-point between the cylinder C and the presser-roller A.

E is a table or supporting-surface for the fluting, on which the work is received, and which leads up to the machine, and its surface is about level with the top of the band-wheel IOO m, in which are slots m', through which pass the screw-pins m2, by means of which the guides MM are held fast to the plate E, and by loosening the screws m2 the guides M M can be moved backward or forward through the slots m in the bars m. Y

The operation ofthe machine is as follows:

It is set in motion by a crank or other means in the direction. of the arrows in Fig. 3. A length of fluted fabric which it is desired to press or crease permanently is fed into the machine on the table E between the guides M M, so that the central or other portion of the flutes can be very gradually pressed down by the converging pressing-surface, and finally flattened. The result is accomplished, because as the goods advance in the machine the liutes are pressed down almost vertically, so that they will be symmetrically and similarly laid,

and as the presser-roller A presses down the folds upon the cylinder C they receive a permanent set or crease.

The guides M M serve not only to keep the iiuted fabric in proper position while'it is passing between the bands, but they also serve to hold back the uted fabric and regulate to some extent the speed with which it passes between the cylinder C and the presserroller A.

By proper mechanism, when desired, a gumcord can also be fed under or above the tinted fabric, or both above and under the same, and between the cylinder C and the presser-roller A.

It is obvious that the mode of operation of this machine may be extended so as to have several pairs of bands moving in the same machine, each pair making a separate pressure or crease in the iiuted fabric which is passing through the machine, intervals being left between the bands for the passage of the parts of the iiuted fabric which are not to be pressed.

What I claim as my invention, and desire to secure by Letters Patent, in a machine for creasing uted fabrics, is

1. In a machine for feeding and creasing uted fabrics, the combination, with a supporting-surface suitable for such fabrics, of an endless rotating pressing'surface slowly converging toward the supporting-surface, and

adapted to iiatten and crease one or more portions of the iuted fabric, leaving other portions unflattened, substantially as described.

2. The endless bands h h and t' i, in combination with the presser-roller A and cylinder C and the wheelsB and D,when constructed and arranged to operate substantially as and for the purpose set forth.

3. In a machine for creasing fluted fabric, the combination of the cylinder C with the presser-roller A, mounted upon a movable center and controlled by a spring, fpr the purpose of varying the pressure asv desired, substantially as described.

4. The band-rollers B and D, mounted on opposite en ds of a vibrating beam, for the purpose of equalizing the tension of the bands, substantially as described.

5. The band-wheels B and D, with thelever L and the screw l, combined and arranged substantially as described.

6. In a machine for creasing liuted fabric.. the combination of the presser-wheels A and C, geared with the band-wheels B and D, substantially as described.

7. In a machine for creasing iiuted fabric,

vthe combination of the table E with the bandwheels B and D, substantially as described.

8. In a machine for creasing luted fabric, the combination of the table E with the guides M M', substantially as described.
