CALICO-PRINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 403,001, dated May '7, 1889.

Application filed July 2, 1888.

To all whom it may concern.-

Be it known that I, JAMES SUTHERLAND, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Calico-Printing Machines, of which the following is a specification.

My invention relates to the production of calico prints and like fabrics which have the pattern upon each side, the object of my invention being to so effect the printing of such fabrics that the pattern on one side will register accurately with the pattern on the other side, and thus impart to the fabric the appearance of one in which the pattern is produced by weaving rather than printing. This object I attain in the manner hereinafter set forth, referencebeing had to the accompanying drawing, which shows an outline diagram of sufficient of a calico-printing machine to illustrate my invention.

A is the main cylinder of the machine, on opposite sides of which are, in the present instance, pairs of impression-rolls B B B B, on which is formed the pattern to be printed upon the fabric. These rolls may be provided with any of the inking devices common in ordinary calico-printing machines.

Passing around a portion of the cylinder and around suitable supporting and guiding rolls a is the usual blanket, D, and passing around a portion of the cylinder outside of this blanket is a sheet, F, which is drawn from a roll, 1), passes over suitable carrier and guide rolls, d, and is wound upon the roll f.

Between the impression-rolls B B and the cylinder A are interposed bearing-rolls G G, and the fabric, as, which is to be printed passes around guide-rolls g, and thence up between the rolls B and 'G, being printed on one side by the rolls B in this passage. The fabric passes around the upper roll, G, and the direction of its movement is thus reversed, the fabric passing down around the lower portion of the cylinder with its printed side in contact with the sheet F, which thus receives the offset from the printed fabric and prevents blurring of the design. IVhen the fabric reaches the opposite side of the cylinder, the design is impressed upon the outer face of the same by the rolls B B, and the fabric, with its backing-sheet, then leaves the cylinder,

the fabric being drawn off to suitable drying machinery and the backing sheet being wound upon the roll f. This backing-sheet is usually of unbleached material, and the offset upon the same is Washed out in the subsequent washing and bleaching operations to which it is subjected, a fresh unbleached sheet being used as the backing for the new sheet of fabric which is being printed.

The rolls B B B B always preserve precisely the same lateral position in respect to the cylinder, and as the fabric is immovably held in position laterally in passing around the cylinder it follows that, supposing the design upon the rollers B to be similar to that upon the rollers B, the impressions upon the opposite sides of the sheet 00 must necessarily accurately register with each other, so that the fabric presents the appearance of having a pattern produced by weaving, whereas if the design is printed upon the opposite sides of the fabric in different machines it is almost impossible to accurately register the two impressions.

In many cases it is advisable to interpose a backing fabric between the strip :10 and the bearing-rolls, so as to provide a comparatively yielding bed for said fabric 00 when the impression is being formed thereon by the rolls B B. For this purpose I provide a second strip, F, which is drawn from a roll, m, passes around guide-rolls i, thence between the rolls B and G, around the upper roll, G, down out side the fabric as in its passage part way around the lower portion of the cylinder A, and thence around rollers t" to a roll, n, on which it is wound.

It will be understood that the rolls B B and G are so driven as to have the same surface speed as the cylinder A, and by preference the rolls controlling the movement of the blanket D and strips F F are likewise driven.

Although I have shown two impressionrollers in each set on opposite sides of the cylinder A, there may, as will be evident, be more than two, as the variety of colors in the design to be produced may require, or there may be butone ofthese rolls on each side of the cylinder.

Having thus described my invention, I claim and desire to secure by Letters Patent-- 1. The combination of the cylinder of the press, two sets of impression-rolls 011 opposite sides of the latter, and bearing-rolls interposed between one set of impression-rolls and the cylinder, whereby the sheet to be printed can, after passing bet-ween said set of impression-rolls and the bearing-rolls, be reversed and carried around the cylinder to receive the impression from the other rolls, all substantially as specified.

2. The combination of the cylinder, the blanket, the backing-sheet F, two sets of impression-rolls on opposite sides of the cylinder, and bearing-rolls interposed between one set of impression-rolls and the cylinder, and serving as a means of reversing the direction of movement of the fabric to be printed, so as to direct it around the cylinder to the other set of rolls with its printed face in contact with the backing-sheet, all substantially as specified.

3. The combination of the cylinder, the blanket, the two sets of impression-rolls B B on opposite sides of the cylinder, the bearing-rolls interposed between the cylinder and the rolls B, a l'Jacking-shcet, F, passing; around the cylinder outside of the blanket, and a second backing-sheet, F, passing between the rolls B and G, and then down between the latter rolls and the cylinder, all substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES SIT'JIIERLAN'D.
