CASE A.

T 0 all whom it may concern:

Be it known that I, GEO. W. OASILEAR, of Washington, in the county of Washington and District of Columbia, have invented certain new and useful Improvements in the Method of Engraving Bank-Note Plates; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing making a part of this application.

My invention relates to a novel method of producing plates for printing bank notes, checks, bonds, &c., where lettering is used; and has for its object the production of such plates more rapidly and at much less cost than has been heretofore done.

Prior to my invention theusual way of en graving names and titles upon plates for printing bank-notes, &c., has been to cut the same by hand with the customary tools of the workman, the bordering, vignettes, 850., being produced by the transferpress. WVhere a large number of plates are required, having dilferent names and titles thereon, the saving of time and money in their production becomes a matter of grave importance, the knowledge of which has led me to this my present invention.

In order that those skilled in the art may fully understand the same, I will describe the various steps taken in my improved method.

I first engrave upon a sheet or plate of steel of the proper size a complete alphabet of any required style, plain, ornamented, or script, in lower or upper case, as may be selected. I then harden this plate and transfer the alphabet to the face of a soft-steel roll by means of the well-known transfer-press. This produces the alphabet in relief on the face or periphery of the roll.

Figure 1 illustrates the first step, showing the alphabet as first engraved upon the plate; and Fig. 2, a series of words or titles produced from the roll, which is accomplished by rolling in one letter at the time, the roll being turned to present such letters as are successively required to form the words. Fig. 3 and Fig. 3 illustrate theroll with the alphabet taken up upon its periphery.

After the final plate is thus en 5 aved I then lay upon it an etching-ground, s h. as is used by engravers, and with the rul g-machinc rule a shade around the letters, hich, when properly treated with acid, con 1; cts the letters all together; or they may, afw r being laid down properly, be treated in any ther known manner; or the independent lett s of the alphabet on the roll may be shad or ornamented, as seen in the word an urn on the drawing. l 1

It will thus be seen that the t st or initial plate of any number and variety I ay have the lettering engraved by mechanic j means in a less number of hours than it W0 1 d require in days by the. present known syste and that any number of plates having v ying titles, &c., may be printed or engrave from a single roll. 1 I

I am aware that the transfer ress is old, and do not wish to lay any claim o the broad idea of transferring letters orch f aoters from a plate to a roll and back to a pla e; I am also aware that bank-note plates h ebeen engraved by means of rolls having ovable letters or type inserted in their peri heries, and that engraving-rollers with prds, signs, and characters produced in relie upon their peripheries substantially in thenanner described in my invention have bee employed; but neither of these in their resp 1 two methods of operation produce resul I similar to mine, and consequently such I not claim; but l 1 What I do claim as new, and e-sire to secure by Letters Patent, is- 1 1 The method herein described 0, 1 engraving titles and words upon bank-no c plates by means .of a roll having a partial r complete alphabet produed upon its peri ery, as described, and operated substantial] :in the manner herein setforth. l 1

In testimony whereof I have 1 ereunto set my hand and seal this 27th day a March, A. D. 1873.
