EDWARD J .STEPHENS AND HIRAM E. GREEN, OF PAWTUGKET, R. I.

MACHINE FOR4 PRINTING YARN.

Specification forming part of Letters Patent No. 57,592, dated August 28, 1866.

To all whom it may concer/rt:

Be it known that we, EDW. J. STEPHENS and HIRAM E. GREEN, of Pawtucket, in the county of Providence and State of Rhode Island, have invented a new and Improved Machine for .Printing Yarn; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l represents a longitudinal vertical section of this invention, taken in the plane indicated by the line .t Fig. 2. Fig. 2 is a plan or top view of the same.

Similar letters of reference indicate like parts.

This invention relates to an improvement in that class of machines on which a patent has been granted to us Marchwlhglml.

Our present invention consists in printing` yarn by means of one tinted and one plain roller, the tinted roller being provided with the requisite quantity of color from a suitable box or trough.

The yarn in passing through between the two rollers is printed simultaneously on both sides, and it takes up the color from the high parts or ridges of the tinted roller and from those parts ot' the smooth roller which come opposite said ridges as said rollers revolve. The color on the plain roller is spread by the action of an additional roller, which is covered with felt, cloth, or other textile or soft material, and which bears hard on the surface ot' the plain roller in such a manner that by the action of the soft or elastic covering the color on the plain roller is spread into a thin lm, all the surplus color being forced off at the ends, where it collects in suitable troughs.

A represents a frame ot' Wood or any other suitable material, which forms the bearings for the axles of the printing-rollers B B', the spreading-roller C Gf, and the color-roller D, which takes up the color from the trough E and transmits it to the roller C', by which itis transferred onto the surface of the iiuted printing-roller B'. These three rollers B C D are geared together by suitable cog-wheels, and they may or may not be geared together with the two remaining rollers B C.

The roller Bis plain, and its boxes a are made to slide on the frame, so that said roller can be set up against the surface of the tinted roller, and it is adjusted in the desired position bythe set-screws b. Said plain roller is supplied with color from the tinted roller, and the color thus supplied to it is spread in a thin lm by the action ot' the roller C, which is covered with felt, cloth, india-rnbber, or other textile or elastic material, and which is set up against the surface of the plain roller B by means of set-screws c. By the action of this roller all the surplus colori-i, transferred to the plain roller B from the roller B is squeezed off over the the ends, and just enough is left. on the surface of said plain roller to produce the desired effect. The yarn in passing through between the two rollers is exposed to a pressure only on those parts where it comes between one of the ridges of the tinted roller and the surface of the plain roller, theint-ervening parts being left uncolored, aud the operationof printing the yarITTs greatly facilitated.

When two fluted rollers areused, said rollers must be iliade exactly of the same diameter, and arranged to revolve with exactly the same superficial speed, so that the ridges of one roller are opposite those of the other. But, if one of the printing-rollers is plain, no `-particular care need be taken in regard to size 6rN speed of such rollers, and the printing is effected in an easy manner, provided the roller C, which serves to spread the color on the plain roller, is in the proper condition.

The color squeezed olf over the ends of the rollers B G collects in troughs F, which are movable, so that the color can be conveniently transferred back to the trough E whenever .it may be necessary.

What we claim as new, and desire to secure by Letters Patent, is-

The use, in machines for printing yarn, of the plain roller B and tinted roller B', iu conlbination with each other and with suitable color-rollers, substantially as and for the purpose set forth.
