IMPROVEMENT IN ROLLERS'FOR FLUIING-'MACHINES The Schedule referred to in these Letters Patent vand making part'. of the Dame To all cham 'it may concern:

Be it known thatI', HENRY G. PEARs0N,'of the certain Improvements in Fluting-Rollers; and I doV hereby declare that the lbllowing, taken in connection with the drawings which accom pany and form part oi this specification, is a description of my invention, suficient to enable those skilled in the art to practise it.

My invention relates to a novelfmode of constructing flirting-rollers, adapted for machines which impart a tluted character to textilev or similar goods, under the action of heat and pressure; and

It consists in forming the roller of sheet-metal, or thin tubing, and corrugating the same, and applying the same to the hollow mandrel, which is to give the! revolution to the roller when` in the machine, all as H eretofore, the rollers of fluting-machines have been made of cast-metal, the ribs or teeth having been cast integral therewith and after being cast, they require to be finished upon their exterior surface, at considerable cost and labor, in order to give a smoothness, which is necessary to avoid cutting or injuring the fabrics to be operated upon, and which are sometimes of very delicate texture. It is also very desirable that there should be no sharp edges or angles upon the teeth. This finishing or tiling away also wastes some of the material, (usually brass,) and to cast them, ref qnires that each roller should have considerable thickness of material beneath its grooves, in order to insure sufficient strength.`

Another mode of making such rollers, has been to cnt the longitudinal flutes, by appropriate machinery, in the surface of a cast tube. This is still more expensive, and requires, also, much labor in smoothing and finishing.

Figure 1, ofthe drawings, illustrates my invention, and shows, in perspective, the sheet-metal corrugated tube or sleeve applied to the hollow mandrel which supports and carries it.

Figure 2 is an end View of the sleeve itself, and

Figure 3, an end view of the mandrel as made when the sleeve is to be applied, so as to be readily removed.

The sleeve A, I make of thin metal, preferably of brass, and corrugate it, to give it its flutes, either in sheets, in any well-known manner, and afterward bend it into tnbularfomi, and unite the edges; or, I take a tube of4 larger diameter than that of the finished roller, and first tapering down'one end, so as to admit it-between the drawing-rollers, which are to impart to it its corrugations, it is then passed between such rollers, emerging in 'the finished state; but the mode I deem the best, is to force the tube through a drawplate, or a succession of draw-plates, in progressive series. smooth and true, and free from any roughness or sharp edges, and needs no filing or finishing.

B is a hollow mandrel, made of appropriate size to receive and hold snugly the sleeve A, which is to be free to be readily slidden on and off at any time, and it has, at suitable' points'thereon, one or. more projections, C, each adapted to enter a groove of the sleeve or tube, to prevent the same from slipping during th revolution ofthe mandrel, and so that the two shallr revolve as if they were one.

D is an end-pieceor cap, atlixed to one end.of the mandrel B, its central opening serving as a means for securing the same to the revolving shaft of the machine; or the hollow mandrel may itself rest in bearings in the frame Of Ythev machine, and in such case, any pin vor detent within the tube would serve the purpose of the piece D, to limit the position of the heating-iron. l

My compound rollers may be applied in iuting-machine, as usual.

AImlependentl-y of' the cheapness andl simplicity of my mode of making the rollers, they have also other .A

advantages, among which are the following: Finer or coarser-teethed rollers may be substituted at a moments notice, and with but slight expense, one machine thus answering the place of many, by

merely changing the corrugated sleeve, and' disturbing no other portion ofthe apparatus. The heat which may have been imparted to the mandrel is retained during this change, whilst to change the rollers ofthe usual construction, the substituted ones must `be heated entirely anew.

The mandrel may be made of thin tubing, and thus the heat required -is less, and is more easily imparted to the iiuted sleeve; and the hollow flutes ofA the sleeve form chambers, to receive the heat, (and they may be closed at the ends, if desired.) 'lhe mandrel may also be perforated in lines with the flutes, or otherwise, and thus allow the heat from the heating-iron to pass more quickly and directly to the outer sleeve,

In some cases, I ijll the open spaces between the flutes and the mandrel with metal or composition.

The corrugated sleeve may be held to its mandrel by soldering,brazing, riveting, or in any way which will permanently hold them together, in cases where itis not important to have it removable. l

I 'cla-im a roller for iiuting-machines, composed of -a tubular corrugated sleeve, applied to the hollow snpporting-mandrel or shaft, substantially as set forth.
