The machine thus constructed has many advantages in construction and use. It will operate successfully upon goods of any desired length. The flexible bands or chains carrying the overlapping teeth may be extended as far as may be desired and the needles being supported and guided closely in the recesses in a long succession of teeth may be made slender if desired, without danger of bending them under the pressure of the goods.

When in use, the action will be automatic, first to take in the goods, next to form the pleats or flutes, and to thread them over the needles and finally to feed the pleated goods over the needles throughout the desired length of the pleating.

The spur gears running in mesh with each other and by means of which accurate timing is obtained are desirable for general use, but if a more accurate form of pleating tooth is employed as for some particular work, the

timing gears may be dispensed with.

The machines are adapted for use in fluting, -pleating,'ruffling or gathering, and are adapted to producing any form of fabrics in which the flutes or corrugations are held together by means of threads running centrally or nearly so through them. 7

One or more needles may be employed .according to the character of the work and goods of one or more thicknesses may be pleated, several thicknesses being employed when it is desired to give the pleats or flutes a padded or puffed appearance.

These machines are ideal for machine type of power drive.

Having described the invention what I claim as new and desire to secureby Letters Patent is:

1. An automatically acting fluting machine, comprising a main frame, a pair of longitudinally spaced shafts therein, an upthe sewing per frame pivoted to said main frame, at one 1 side thereof, a .pair of spaced shafts in said upper'frame parallel with the shafts in said main frame, pulleys on said shafts, and upper and lower endless flexible toothed fluting members connecting the pulleys on each respective pair of shafts, the teethon one flexible member intermeshing in turn with the teeth on the other flexible member, a needle support in line with the common pitch center of said flexible fluting members, and needles on said support, the intermeshing teeth of said endless flexible fluting members being provided with marginal guide openings in which said needles are supported throughout the fabric covered' portion thereof, to prevent buckling thereof.

2. An automatically acting fluting machine, comprising a main frame, a pair of longitudinally spaced shafts therein, an upper frame pivoted to said main frame at one side thereof, a pair of spaced shafts in said upper frame parallel with the shafts in said main frame, pulleys on said shafts, and upper and lower endless flexible toothed fluting members connecting the pulleys on each respective pair of shafts, the teeth on one flexible member intermeshing in turn with the teeth on the other flexible member, a needle support in line with the common pitch center of said flexible fluting members, and needles onsaid' support, the intermeshing teeth of said endless flexible fluting members being provided with marginal guide openings, in which said needles are supported throughout the fabric covered portion thereof, to prevent buckling thereof, and resilient means for depressing'said pivotedframe to exert vertical pressure upon both ends of said flexible fluting members, and upon the intermediate portions thereof, and to clamp said needles between said chains.

3. In a fluting machine in combination, a pair of spaced upper shafts, and a pair of parallel equally spaced lower shafts, an endless flexib-le chain connecting each pair of shafts, said chains being provided with intermeshing teeth, a fixed support and bearings for the lower pair of shafts, a common pivoted support and bearings for the upper pair of shafts, and means for exerting pressure upon said common pivoted support, nee- 1 dles passing between said chains at the pitch line of said teeth, said teeth on said chains being provided with marginal recesses for the reception of said needles, said pressure being equally distributed over said chains and needles.

4. In a fluting machine, a pair of parallel endless toothed chains and operating shafts therefor, the teeth on one chain intermeshing in turn with the teeth on the other chain said teeth being provided with marginal recesses, a rigid needle support at one end of said machine, and a needle extending through the common pitch line of said endless chains, and rigidly supported in said marginal recesses therein, and means for exerting uniform pressure upon the entire length of the upper chain and needle.

5. Ina fluting machine, a pair of upper and lower parallel endless toothed chains and ,1 operating shafts therefor, the teeth on one chain intermeshing in turn with the teeth on the other chain said teeth being provided with marginal recesses, a rigid needle and a support thereforat one end of said machine,

said needle extending through the common pitch line of said endless chains and rigidly supported in said marginal recesses therebetween, and means for exerting uniform pressure upon the entire length of said upper chain, and means for giving regularity of movement to sald needle supporting chains. In testimony whereof I affix my signature.
