ERNST BROSEMANN, OF NEW YORK, N. Y.

MACHINE FOR CREASING FLUTED FABRICS.

SPECIFICATION forming part of Letters Patent No. 228,309, dated June 1, 1880.

Application filed July 1, 1879.

To all whom it may concern:

Be it known that I, ERNST BROSEMANN, of the city, county, and State of New York, have invented certain new and useful Improvements in Machines for Greasing or Plaiting Fluted Fabrics, of which the following is a specification.

The invention relates to that class of such machines in which the fluted fabric is compressed between heated surfaces, and the plaits formed are held in place by superimposed cords.

It consists in the combination, with suitable pressure-rollers provided with flanges, of gas-pipes having their perforated or burner ends curved and located behind one of the flanges of each of said rollers, for the purpose of heating the rollers, the flanges meanwhile protecting the fabric passing between said rollers from the flame and smoke of the gas.

It further consists in the combination, with the pressure-rollers and adjustable feed-table provided with cord-guide holes, of an upper adjustable cord-guide, as will be more fully hereinafter described; and, further, in the combination, with the pressure-rollers, of the adjustable table and a novel arrangement of laterally-adjustable and vertically-adjustable guides, for guiding the fabric in a proper manner to the rollers, as will be hereinafter more fully described.

In the drawings, Figure l is a front elevation of the machine. Fig. 2 is a vertical section on line a :r, Fig. 1. Fig. 3 is a detail section, showing the form of the rims of the pressure-rollers. Fig. 4. is a plan view of the cord-guide and a portion of the feed-platform. Fig. 5 is a detail side view, partly in section, illustrating the adjustable feed-table. Figs. 6 and 7 are diagrams showing the extent of opening between two pairs of rollers of differentdiameters at a given distance from their points of contact. Figs. 8, 9, and 10 are diagrams illustrating the action of differentsized rollers.

The letter A indicates the supporting-frame of the machine, held together and braced by suitable cross-bars, and B is a shaft mounted in vertically-movable adjustable bearings at the top of this frame.

To the middle of this shaft is fixed the roller D, from each side of which, near its periphery, projects a flange, d.

The letter O designates a similar shaft mounted in fixed bearing below the shaft B, and carrying a fixed roller, E, with flanges e projecting on each side near its periphery.

To the projecting ends of the shafts B and O are fixed gear-wheels B 0, connected by intermediate gears B 0 Upon the end of shaft 0, opposite the gear-wheel G, is fixed a larger gear-wheel, U which meshes with a pinion, 0, fixed upon a short shaft journaled in the frame A and a bracket, a, secured thereto. This short shaft is provided with acrank, c, by which the machine may be driven.

Gas-pipes F and G have their curved perforated ends located just behind the flanges d and e on one side of the rollers D and E, respectively. These pipes are branches of a main pipe, and may be supported in proper position in any suitable manner. Their office is to heat the rollers.

To the front of the frame A is secured an adjustable platform, H, pivoted, near its outer edge, to brackets or arms I by means of an attached rod, J, the ends of which fit in bearings in the outer ends of said arms. An inward extension, K, of the table H has its edge bent upward and slotted, as shown at 70, Fig. 5, and a clamp-screw, It, serves to secure said edge.

The letters h h indicate cord-holes near the inner edge of the platform proper, H. These holes serve as guides for the cords, which are to be pressed upon and secured to the under side of the fabric in course of plaiting, as will be hereinafter described.

The letters L L indicate horizonally or laterally adjustable gages mounted upon the table H, for guiding the edges of the fluted fabric between the peripheries of the rollers, and M M are vertically-adjustable guides mounted upon said gages L, and serving to guide the fluted fabric so that a horizontal line drawn through the centers of the flutes will coincide with the horizontal plane of contact of the peripheries of the rollers, this having been found to be the proper position in which the fluted fabric should be fed in order that the flutes may be compressed into even plaits.

From the front of the frame A projects a bracket, N, from the front cross-bar, N, of which an upper cord-guide, 0, extends downward and inward, terminating above the table H at a point a little in front of the cord-holes h in said table. This cord-guide O has in its end cord-holes 0 0, similar to those in the table, and said guide is vertically adjustable by means of a slot, n, and screw it at its upper end.

The letter R indicates a bracket projecting rearwardly from the frame A, and carrying a stripper-blade, S, projecting upwardly and lyin g against the periphery of the lower roller, E, to prevent the plaited fabric from adhering to and being carried under said roller.

In creasing fluted fabrics I have found it desirable to use coinpressing-rollers of as great diameter as practicable, so that the flutes will, when fed in a line coincident with the plane of contact of the rollers, be gradually and evenly compressed.

In diagrams Figs. 6 and 7 are shown curved lines representing the peripheries of corresponding rollers. In Fig. 6 the rollers are of large diameter relatively, so that the opening between the rollers at a given distance from their point of contact is much less than at the same distance from the point of contact in Fig. 7. In thelatter case, when the top of one flute (as goods are ordinarily fluted) comes in contact with one of the rollers it will be carried forward and the flute crushed outof shape before the succeeding flute has come in contact with the other, so that each flute is compressed on one side, while the other simply yields, not being supported until the preceding flute has already been compressed sidewise. Thus the flutes are compressed irregularly and into plaits inclined in one direction, as is shown in Fig. 9, or the fabric is simply straightened, as shown in Fig. 10, according to the stiffness or pliability of said fabric. hen, however, the rollers are of large diameter the crest of one flute is only momentarily in contact with one of the rollers before the succeeding flute comes in contact with the other roller, and thus both sides of each flute are supported at the time actual compression takes place, and all are flattened and folded equally in both directions,as shown in Fig. 8.

In operating the machine the table H and guides L and M are to be adjusted to guide the fluted fabric, as heretofore explained, so that the centers of the flutes approach the point of contact of the rollers in a line coincident with a tangent line drawn from said contact-point. Moistened cord is passed through the holes 0 0 in guide 0, and through hole It in table H, and led between the rollers in such manner as to lie aboveand below each edge of the fluted fabric. The material being then fed over the table and between the guides, it passes between the peripheries of the rollers, the flutes are compressed into plaits, and the cords are firmly pressed upon these plaits, and as they are dried by the heat of the rollers they adhere to said plaits and hold them in position. The cords should be moistened in a lnucilaginous liquid.

Having now fully described my invention, what I claim is l. The combination, with the pressure-rolL ers D and E, having the flanges d and c, of the gas-pipes F G, having their ends perforated, and located behind and adjacent to the flange on one side of each of said rollers, substantially as described.

2. The combination, with the pressure-rolL ers, of the adjustable table H, provided with the cord-holes h h, and the adjustable cordguide 0, provided with the cord-holes 00, substantially as and for the purpose set forth.

3. The combiuation,witl1 the pressure-rollers, of the adjustable table H, carrying the laterally-adj ustable guides L and the vertically-adjustable guides M M, whereby the fluted fabric is guided with the centers of its flutes on a line tangent to the point of contact of the rollers, substantially as described.
