IMPROVEMENT IN THE ORNAMENTATION OF METAL, GLASS,

The Schedule referred to in'tllese ilett em Patent and part ofthe same.

I, BEEJAMIN GEORGE GEORGE, 017 47 Hatton Garden, London, in the county of Middlesex, lithographer and printer, do hereby declare the nature of into various articles, the object being a perfection not attainable by the ordinary methods now in use, as well as a large economy in the cost of production.

Pictures, ornamental designs, tablets, and showcards transferred on metal or' other materials, and used as pictures, advertisement-tablets, or in the manufacture of goods of an ornamental and artistic character, to which my improvements relate, have hitherto been prepared in the following manner, viz

The surface of a sheet of metal or other material is painted over in oil-color, and is then dried in a stove or otherwise, and, for good work, it is afterward rubbeddown with pumice or otherwise, to obtaiua smooth surface, and these processes are repeated 'onceor more times, according to the finish and polish required.

The picture, design, or show-tablet, which has been previously printed on what is known as transfer-paper,

is then transferred upon this painted surface of the plate or other-material, and is afterward varnished and dried.

By my improvements I avoid this expensive and imperfect method of producing the painted ground on the surface of the plate previous to the process of transferring the printed work; and to this end I adopt the following means:

' 'I first prepare a design, such as a picture, ornamental design, or show-tablet, and having lithographed it or engraved it, I print it in theordinary manner of printing on transfer-paper, and when the color or colors are well dry I proceed with one of the first processes of my improvements, as follows: v

I prepare a lithograph or suitable metal plate or wood block, or other printing surface, to print one uniform-flat surface of color the dimensions required, and upon and all overthe picture or design or showtablet; or, in other words, all over and-upon the surface of the transfer-paper, on which is printed the picture or design or show-tablet, I print one or more layers of color in white, or of whatevertone or tint I desire the ground to be, thereby covering and obliter-. atingthe entire printed picture, design, or showtablet, and making it to appear like one flat sheet of printed color.

I now take a sheet of metal, either tin, iron, copper, brass, or other metal or amalgamation thereof, or it may be glass or wood, or other suitable material, and having rubbed a little oil or varnish over it to make it jtacky,.I proceed to transfer the printed work in the usual way, and the surface of color last printed upon and over the picture, design, or showetablet is, by the process of transferring, reversed, and becomes the ground on which the picture, design, or show-H tablet lies after the transfer-paper is removed; for by transferring the order of the printed colors is changed, and this last printed fiat ground. coming first on the metal, the picture, design, or show-tablet on the transfer-paper, which was covered by this printed flat ground in 'the.last operation of printing, will appear on the top of it, and the printed ground thereby be-, comes the substitute for that made by the common and expensive process of first preparing the ground on the, metal by theusual means of hand-painting.

Whenthe ground on which ,the picture, design, or

show-tablet is to lie is required tube of a dark tone or color, or black, I then print one or more layers of white color over and upon the various colors forming the printed picture, design, or show-tablet on the transferpaper before printing the dark or black ground, and this white color coming directly upon the picture, design, or show-tablet, forms a backing, and

prevents the colors composing it from being deteriorated by the dark or black ground which would otherwise'come in contact "wit-hand upon them, and thereby destroy their purity and brilliancy.

After the transfer of the printed picture, design, or show-tablet tothe metal I pass it through a rollingmachine, such as is used to glaze paper, and this process gives a'beautiful, smooth, and polished finish to the transferred work, and prepares it to receive the varnish covering, which is then applied in the nsual wa and it is finally stoved to harden.

By my process. of printing and transferring, the pictures, designs, and show-tablets or letterings thus made are doubly useful, for not only may they be exhibited in the ordinary way, but they may be used as transparencies, as the thin white or tinted ground, although sufficient to back up the design and so form a ground for the printed picture or design or showtablet to lie on according to my system, is, never-- theless, not thick enough to obscure the light when placed behind so as to exhibit them as transparen- 'eies; and this is very important, for, as transparencies on glass are commonly made, they cannot be seento advantage when the light is before them, from the want of this white or tinted background or ground to back up the picture or design.

By the. above process 1 amiable to produce, with great efi'ect and little cost, many beautiful works of art for domestic and general use, as well as pictures, illuminated texts, reading-sheets, 800., for; use in and for the adoriiment of schools, cottages, 850., the fi'ee introduction of which has hitherto been prohibited by their cost.

Having now herein described my invention and the several methods by which it is'performed,

' I claiui- The process her'eindescribed of transferring printed ork on 'the surface of metal or other suitable materra BENJAMIN GEORGE GEORGE. Withessesz F. W. Armsox, W.- D. Wooo.
