To THOMAS GREIG, of Rose Bank, in the parish of Bury, in the county of Lancaster, calico printer, for his invention of a mode of embossing and printing, at one and the same time, by means of a cylinder or roller on goods or fabrics made of or from cotton, silk, flax, hemp, and wool, or any one or more of these materials, or on paper. [Sealed 10th November, 1835.]

THIS invention consists in a novel adaptation and arrangement of machinery for embossing and printing silk, cotton, woollen, paper, and other fabrics or goods, in one or more colours, at one operation, either simultaneously, or consecutively, by means of revolving cylinders.

The construction of this machinery in its combined form, and its mode of operating, will be understood by reference to the drawing in Plate III.; and the following expla

nation thereof, fig. 1, in Plate III., exhibits a front elevation of the printing and embossing machine; fig. 2, is an end view of the same; fig. 3, represents the reverse end; and fig. 4, is a vertical section, taken through the machine in the same direction and parallel to fig. 2; the respective letters of reference indicating the same parts in all the figures.

The machine, as represented in the drawing, is furnished with three distinct printing cylinders of copper or other suitable material A, B, C, with their necessary appendages, for printing three different colours upon the fabric as it passes through the machine: either of these cylinders a, B, or c, may be employed as an embossing cylinder, without performing the printing process, or may be made to effect both operations at the same time.

The fabric or goods to be operated upon being first wound tightly upon a roller, that roller is to be mounted upon an axle or pivot, bearing in arms or brackets at the back of the machine, as shown at D. From this roller the fabric a, a, a, a, is conducted between tension rails, and passed under the bed cylinder or paper bowl E, and from thence proceeds over a carrier roller F, and over steam boxes not shown in the drawing, or it may be conducted into a hot room, for the purpose of drying the colours.

The cylinders A, B, and C, having either engraved or raised surfaces, are connected to folding rollers b, b, b, revolving in the ink or colour troughs c, c, c ; or endless felts called sieves may be employed, as in ordinary printing machines, for supplying the colour, when the device on the surface of the cylinders are raised: these cylinders may be furnished with doctors or scrapers when required, or the same may be applied to the endless felts.

The printing cylinders may be driven by gear, and pressed against the paper bowl in the way exhibited in the

drawing, or by any other convenient means, the particular manner of doing which is not claimed as any part of the invention, but is exhibited for the purpose of rendering the construction and adaptation of all the parts of the machine evident.

The situations of the doctors, when required to be used for removing any superfluous colour from the surface of the printing cylinder, are shown at d, d, d; those for removing any lint which may attach itself at e, e, e. They are kept in their bearings by weighted levers and screws, and receive a slight lateral movement to and fro, by means of the vertical rod m, which is connected at top to an eccentric on the end of the axle of the roller H, and at its lower end to the horizontal rod n, mounted at the side of the frame, (see fig. 2,) to this horizontal rod arms 0, 0, 0, are attached, which are connected to the respective doctors; and thus by the rotation of the eccentric, the doctors are made to slide laterally.

When the cylinders A, B, or c, are employed for embossing only, those doctors will not be required. The driving power is communicated to the machine from any first mover through the agency of the toothed gear, shown in fig. 2, which gives rotary motion to the cylinder ®, and from thence to the other cylinders A, and c, by toothed gear shown in figs. 1, and 3. The gudgeons of the cylinders A, and C, are supported in blocks f, f, sliding in brackets formed on the side frames of the machine; which blocks have adjustable screws g, g, for the purpose of bringing the cylinders up against the paper bowl, with any required degree of pressure: the cylinder B, is supported by its gudgeons running in blocks h, which blocks slide in the lower parts of the side frames, and are connected to perpendicular rods i, having adjustable screw nuts.

The lower parts of these rods bear upon weighted levers
