IMPROVEMENT IN MACHINES FOR CREASING FLUTED FABRICS.

Specification forming part of Letters Patent No. 171,264, dated December 21, 1875; application led i A September 3, 1875.Y

` To all whom it may concern Be it known that I, JOHN EL BROWN, of New York city, New York, have invented certain new and useful Improvements in Machines for Pressing or Creasing Flutings, which improvements are fully set in the following specification, reference being had' 'to the accompanying drawings.

l In the method heretofore practiced for pressing or creasing flutings a narrow metallic edge space, under the pressing-iron as the operation is performed on each section of the length of the iiuted fabric; and it is also defective because the flute 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 lnore perfect result. e

In the accompanying drawings, Figure l is a plan of my machine. Fig. 2 isa sect-ion in elevation at the line Y Y, showing also the gearing in elevation. Fig. 3 is a section at the line ce x. 4 4 i The same letters refer to similar parts in all the drawings.

Gis a hollow cylinder revolving upon an axis supported by a 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 presserroller, having a cylindrical surface at h. This presser-roller may be made hollow, and may be heated by a gas-jet or other appropriate means. This presser-roller is mounted upon a revolving shaft, which is driven by a gearwheel, a', from a corresponding gear-wheel, c, on the shaft of the cylinder O. The shaft of the presserroller A is supported upon a lever, g, which vibrates around a center, g4, so

placed as to permit a slight, nearly vertical,

movement to the presser-'roller A. Through this lever a set-screw, g1, passes, vhaving a recoil-spring, g3, between its head and the top upon a vibrating beam, which is centered e at K upon the lever L, which is centered also on the frame ofthe machine at L. The upper end of this lever is provided with a screw, Z, whose office isto'tighten or loosen the bands which pass'over the band-wheels by moving the lever L awayy from or toward the cylinder and presser-roller, as required. When this' set-screw is tightened, the beam, which sup* ports the two wheels B and D, accommodates itself to the length of the bands, and assumes the positionwhich will make the tension equal upon both bands. -it'and h h are narrowbands, preferably of metal. The band it h passes around the wheel B and the presser-roller A, and the band t' c' passes around the wheel D and the cylinder O. The centers ofthe baudwheels B and D are farther apart than the centers of the cylinder O and presser-roller A, so that the bands converge as they approach the pressure-point between the cylinder C and the presser-roller A. E is table, 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 D. On the top of the plate E are two parallelguides, M and M', attached to bars 1 l, in which are slots m1, through which pass the screw-pins m2, by means of which the guides` M M are I 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 inthe bars m'.

The operation of the machine is as follows: It is set in motion by a crank or other means in the direction of the arrows 111 Fig. 3. A length of fluted fabric, which it is desi-red to press or crease permanently, is fed into the machine onlthe table E between the guides M M', so that it can be caught between the converging bands h h 4and c' i, and carried along with them toward the cylinder O. As the goods advance in the machine the flutes Q' l ViiLLi are pressed down between the converging bands almost vertically, so that they will be symmetrically and similarly laid; and as the presser-roller Apresses down the folds upon the cylinder C they receive a permanent set or crease. The guides M M. serve not only to keep the fluted fabric in proper position while it is passing between the bands, but they also serve to hold back the iutedfabric and regulate, to some extent, the speed with which it passes between the cylinder C and the lpresser-roller A. By proper mechanism,`

when desired, a gum-cord can also be fed under or above theliuted fabric, or both above and under the same, and between the cylinder C and the presser-roller A.

vIt is obvious that the mode of operation ofl thismachine maybe extended, so as t0 have several pairs of bands moving in the same machine, each pair making a. separatev press-- nre or crease in the fluted fabric, which is,

passing through the machine, intervals being left between the bands for the passage of the partsof the` uted fabric, which is, not-to be pressed.

What I claim as my invention, and desire to secure by Letters APatent in amachinefon creasing flutedfabrics, is-

1. The endless bands hh and M in combination with the presser-roller A. and cylinder:

C, and the Wheels B and D, when constructed and-arranged to operate substantially as and for the purpose set forth.

2. In'a machine for creasing iluted vfabric the combination of the cylinder C with the presser-roller A, mounted upon a movable center and controlled by a spring for the purpose of varying the pressure, as desired, substantially as described.

3. The band-rollers B 'and D, mounted on opposite ends of a Vibrating beam, forthe purpose of equalizing the tension of the bands, snbstantiallyas described.

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

5. In amachine for creasing uted fabric the :combination of i the presser-wheels A and C, geared with the band-wheels B and D, substantially as described.

6. In a machine for creasing iuted fabric the combination of the table E with the bandwheels B and D., substantially as described.

7. Iii-amachine for creasing liuted fabric the combination ofthe table E with the guides M M, substantially as described.
