\ PROCESSFOR PRODUCING PRINTED MUSIC-SHEETS.

To all whom it may concern.

Be it known that I, L'oowie Hess, a subect of the Emperor of Germany, and a resident-of the borough of Manhattan, city,

county, and State o'f'New York, have invented certain new and useful Improvements in Processes for ProducingPrinted of which the following is a specification.

' This invention relates to certainnew and useful improvements in processes for producing printed music sheets.

By the use of my improved process we are not only enabledto produce prints equal in artistic efi'eet to that produced by engraving, and to save valuable time over any method at present employed, but the negative or reverse sketching on a tinned lead plate by a skilled workman is entirely eliminated; the designer, who by the use of my process requires "very little preliminary trainin a, being enabled to make a positiveor natural sketch with simple utensils, thus effectually reducing the cost of both labor and materials. Furthermore, in case errors are made by the designer, they maybe readily and easily erased by means of aglass eraser, and correction may be mader without in any way affecting or'defacing the prints subsequently made in accordance with the sketch. Furthermore, the transparent sheet which, in carrying out my process, has the musicimprinted thereon may be employed over and over again, thus avoiding the necessity of storing unmelted zinc plates.

In general terms, my invention consists in first taking a sheet of transparent paper of suitable size, producing on oneside of such sheet with non-transparent ink the staff lines and other music symbols, placing such sheet face downwardly upon a suitably rep'ared printing surface, subjecting saids eet and surface so produced. v

b More particularly my invention consists in taking a sheet of transparent paper 'provided, with transparent vertical and horizontal hatching lines, printingupon one sideof such transparent sheet with nontransparent ink'the stafl line's, then lightly sketching the music symbols thereon, and

known manner and thenprinting jlirom I the inked wit non-transparent ink the music symbols so sketched, placing the said transthen stamping by means of a metal stamp Specification of Letters Patent. Application filed May 10, 1912. Serial No. 696,352.

responding parts throughout the several views, Figure 1 is a. plan" view of a trans parent sheet provided with transparent vertical and horizontalcross-hatching lines; Fig. 2 is a plan view of a portion of such shwt after the staff lines are imprinted thereon; Fig.3 is a view similar to Fig. 2 after the designer sketches the notes and other symbols from the eomposers manuscript-thereon; Fig. 4 is a view similar to symbols in. opaque ink Fig. 5 isa section in- 'dicating a transparent sheet placed face downwardly over a suitably prepared zine plate; Fig. 6 is employed in my improved process; Fig. 7 is another side elevation at right angles to Fig. 6; Fig. -8 is a top view of the stamp; and Fig. 9 is a plan View of the printing surface of the stamp. y Referring now tothe accompanying draw ings, and follow in out the preferred form of'my invention, take a transparent sheet of paper or other suitable material designated A, into which sheet is preferably imprinted transparent vertical and horizontal hatching lines representedby the light black lines a. These-lines maybe imprinted into the paper orother mater al in any manner such as by the use. of a stencil or other suitable utensil or utensils. I

duced with non-transparent or opaque ink the music staff lines, such as I have designated b in Figs. 2 to 4.- inclusive. I then corn'poserby sketching with a pencil or other sultable utensll synibolsof music, measures and compasses as in the engraving copying maybe done by a person having very little preliminary training, such sketched music symbols being represented in Fig. 3' by The pencil sketch is then inked either by hand or by means ,of music stamps or a music writlng machine,.-in any event using non-transparent or opaque ink. In the preferred form, and toproduce the best results Figs. 2 and 3 after the stamping of the music a side elevation of-a stam I proceed to print upon the sheet thus.pro-' .proceed to copy' I om the manuscript of the sheet and plate to the action of strong light finishing the negative In theaccompanying drawings in which similar reference characters designate cor-- using process heretofore employed except that the I the light lines designated a.

- in the of time and labor, I use music stamps F illustrated in Figs. 6, .7 8 and 9, hereinafter described. i

The stamp F comprisesa base or stamp-i ing portion 1 of metal or othersuitable ma terial, having the note or other symbol represented thereby engraved or raised. in or on its surface, a thin flat vertical handle 1" squared at its edges the thickness of such handle being approximately equal to the space between the cross-hatching lines a so that the same may be employed as a vertical guide in stamping the symbol on the music i sheet'and a transverse guide bar f also hav- 'tance between the cross-hatching lines a a ing a width approximately equal to the disand disposed at right angles to the handle By the use of this stamp I am enabled .place the symbol; With a little practice such symbols maybe positioned with great accuracy.

The top of the handle preferably bears the type of. the symbol represented thereby so t at visible and positive representative characters will appear before the Stamper at all times, and if desired these stamps may be arranged in a type case, the outside of which shows the corresponding symbols, and stamps of course be supplied to the operator in various sizes conforming to all sizesof stafi' lines and spaces in use.

Having now produced a transparent'sheet with transparent vertical and horizontal hatching lines, and with the staff lines and music symbols in opaque or non-transparent ink, I proceed to placethetransparent sheet so preparedupon a metal plate suitably prepared with chromate of potash or other suitable chemical and subject the same tothe action of strong light, then develop such metal plate in the usual manner so that after a suitable period of such subjectiont'o light 1,112 see 1 and subsequent development the stafi lines" and symbols .will appear upon' the metal plate in relief. These-plates may then be further finished soas to eliminate all rough surfaces, whereupon 'niusic sheets may be printed from the same. The .sheets thus distinct and equal in appearance to music sheets produced by the engraving process. 3 v 1 .Hav-ing described my invention, 1' claim:

..1.The process of producing music sheets which consists in taking a sheet of transparent paper dividing the surface of said sheet into minute sections by providing the same with transparent vertical and horizonv tal hatching lines, printing upon one side of such transparent sheet with non-transparent produced will be perfect in all details and as clear,

ink the mus c stafi' lines and other music symbols, placing the transparent sheet face face to the action of st-rong'light to form a negative, developing-said negative plate and printing therefrom. 2. The process of which parent sheet into minute transparent vertical and horizontal hatchproducing music. sheets paper dividingthe surface of said consists in taking a sheet of transsections by providing ing hnes thereon, printing with non-transparent ink upon one side of such transparent 'heet the music sta-fi" lines, sketching the music symbols thereon in pencil, stamping by means of stamping devices inked with non-transparent ink the music symbols so sketched, placing the said 's'heet face downwardly upon a suitably prepared printing surface,isubjecting said sheet and surface to the action of strong light'to' form a negative,
