MACHINE FOR SETTING "UP AND PRINTING MUSIC.

Application filed July 15 1927, Serial No. 206,041, and in- France February 25, 1927.

- My invention relates to an apparatus for the typographical composition and printing of music and to a method in which the music is composed upon a magnetic or 5 electromagnetic table carrying lines analo gous to musical staves on an enlarged scale, as well as the use of small type pieces of magnetic metal having the form of the usual characters, on the same enlarged scale as the staves. Upon the said type pieces is applied a sheet of paper carrying the musical staves corresponding to the ones formed on the table, and thus the composed music can be printed 'upon the sheet; From the said sheet a negative of reduced size is obtained by photography which is reproduced by the known methods.

The said apparatus is chiefly characterized by the following features:

ing reel placed at one side of the magnetic table, through a pair of actuating rollers disposed at the other side of the said table. The paper can be applied upon the said table by means of a vertically movable plate, and it is then drawn forwardat the end of the operation and passes over an inking roller by means of which the staves are printed upon the paper. The electro-magnetic table is arranged to be horizontally slid-able so that it may be brought from under the said printing plate and thus become disengagedduring composition.

The lines upon the said table are formed by cords which are stretched from one end to the other, and the type pieces have suitable notches formed on the under side by which they may be disposed upon the said 40 cords, so that they may be readily placed in the proper position.

The said invention further relates to the following features by way of a modified construction:

a. The composing tablev preferably consists of a set of bars or strips inparallel position and consisting of steel or like metal or alloy of a magnetic nature, which are disposed on the same level at'the top and are spaced apart by flat members of a non- The printing paper travels from a feed magnetic metal or alloy, the bars of the even or odd numbered series alone resting below (against) the magnetic core, while the bars of the odd or even numbered series are connected together at the ends and are placed in metallic contact with the said core by means of these ends, thus forming closed spaced magnetic circuits, and assuring the practically uniform distribution ofthe magnetic flux upon the table whereby the type pieces will perfectly adhere to the latter.

6. The type pieces for the notes or like characters consist of a main or bottom portion of soft steel or like magnetic metal or alloy, upon which is mounted inany suitable manner a type-metal top portion in which the note is represented in relief.

0. A felt sheet or pad is stretched upon the said pressing plate, and to assure the proper tension, one end of the felt sheet is secured to one end of the plate and the other end of the sheet is wound at the other end of the said plate upon a rod of square section which is left unfinished after casting in order to provide a rough surface, and Which is held by small ratchet wheels.

cl. The printed sheet after leaving the machine may be finished or corrected in any desired manner. I may for instance employ an air brush in connection with suitable stencils to form upon the said sheet all the musical characters or signs which may be necessary, such as slurs, braces, ties for quavers, or the like. Any errors in the notes or other parts are preferably corrected by pasting upon the faulty portion, a piece of paper carrying thecorrect notes, and this correction will be quite invisible upon the reduced photographic copy of the sheet.

Further characteristics of the invention will'be obvious from the following description with reference to the accompanying drawing in which,

My apparatus comprises a horizontal table whose width is about twice the width of the.

electro-magnetic plate or type carriage A which is mounted upon the same by means of the rollers 2 adapted to travel upon the rails 3 under the action of a hand wheel 4 which drives, by means of bevel gearing, a shaft 5 to which are keyed the pinions 6 coacting with the racks 9.

The magnetic table A consists of a cast iron plate 7 of rectangular form surrounded by a flanged portion 7 of fiat shape upon which is disposed the coil of conducting wire 8. The said coil carries a current which is preferably regulated by a rheostat (not shown) thus energizing the whole surface of the plate 7 forming the core of the electro-magnet. Above the plate 7 is disposed a steel plate 10 into which are inserted, according to a set of longitudinal lines corresponding to the lines of the musical stave, the steel pole-pieces 12 which are flush with the upper surface of said plate and are separated therefrom by a bushing 13 of a nonmagnetic metal or alloy such as aluminium, the said pole pieces serving to transmit the magnetic flux from one plate to the other. The disposition of the said pole-pieces may be as desired, and their number should be as large as possible in order to obtain the best distribution of the magnetic flux upon the said table.

Across the said table are stretched from one end to the other various sets of cords 14 in parallel position which are optionally metallic, the ends of the cords being wound upon the stretching pegs 15. Each set of cords'comprises a series of five cords 14 corresponding to five lines of the staff. Between the staves are disposed other cords 14 of a different color for marking in the proper manner the position of the type pieces corresponding to the notes between the lines.

The type pieces 17 (Figs. 12 and 1.3) are made of magnetic metal, and consist of a as the quavers for instance, may be formed, I

by juxtaposing several parts in order tolimit the numbers of type pieces. The bars of the music are formed by placing upon the table at the proper intervals the straight pieces 17 having the same height as the type pieces 17.

At the sides of the table A are disposed the flat bars 10 having the same height or thickness as the type pieces 17 and the said bars serve to limit the descent of the platen hereinafter described more in detail thus preventing any damage to the type pieces.

Above the main table or base 1 is disposed, over one-half the width thereof, a frame comprising two vertical uprights 18 and a horizontal cross-piece 19, which supports the type box 20 which also rests upon a crosspiece 21 connecting the said uprights. The said type boX contains the different pieces of type for composing the music. A screw 22 provided with weighted arms is engaged in a nut 23 mounted on the cross-piece 19 and it controls the upward and downward motion of a platen 24 which is vertically slidable between the uprights 18. The said platen has the same width as the table A, and its lower side is faced with a felt member 25 which is secured at one end a, to one side of the platen while its other end is wound upon a square shaft 26, held by the pawls 16, whereby the said felt member may be more or less stretched.

On one side of the said frame is disposed, upon a suitable support, a roll of paper 27 which has the same width as the table A. The paper band 28 travels over the whole length of the table and isengaged between two drums 29-3O mounted at the other end of the frame. The drum 30 may be rotated as desired by a suitable mechanism, and the paper band is finally wound upon a reel 31. Two pairs of rollers 28 at each end are employed to hold the paper and to stretch it below the plate, and the said rollers are pressed together by means of an eccentric.

Upon the cylinder 29 are formed sets of five annular projecting parts or flanges 83 with sharp edges which make contact with the paper wound on the drum 30. flanges are also in contact with the inking rollers 3234 which operate in an ink vessel 35, and the said rollers thus print upon the paper various parallel lines corresponding to the musical staves.

The operation of the said apparatus is as follows To set up the music, the hand wheel 4 Said 1 used to bring the type-carriage A as near as possible to the front edge of the table 1, and the magnetic flux is so regulated as to produce only a slight adhesion of the type pieces, so that they may be readllyput in place. The music may be set up even without energizing the electromagnet, and the type 17 and the bars 17 will remain in place upon the table. The work is set up as above mentioned by placing the type 17 and the bars 17 upon the cords 14 which form lines of the stave. When the piece of work has been completed, the strength of the current,

and hence the adhesion of the type, is increased. The type is inked, and the typecarriage A is brought below the platen 2%. The paper band 28 being'engaged between the rollers 28" is stretched thereby and the platen 241 is lowered by means of the screw 22. Dueto the use of the felt pad 25 and the slight amount of slack resulting from the free unwinding of the reel 27, the notes will be printed instantaneously in-a perfect manner. Theplaten 24 is then raised, and

= the rollers 29 and 34 are rotated so as to draw forward the paper a distance equal to the printing thereon, and the flanges then print the lines of the stave as the paper travels forward.

' The printed bandof paper is then cut ofl and the electric circuit is broken in order to remove the type 17 Whichare employed for other pieces of Work.

To obtain a better distribution of the magnetic flux upon the table ortypecarriage A,

it may be constructed as shown in Figs. 6 and 7. As therein shown the table consists of rectangular bars 37, 38 of soft steel or of a like magnetic metal or alloy which are spaced apart by the bars 39 of'a non-magnetic metal or alloy such as brass or bronze, the set of bars being pressed together by bolts 40 of a non-magnetic metal.

The bars 37 are wider than the bars 38 and will thus rest directly upon the core 7 of the table, as shown in Fig. 7. The bars 38 extend outwardly at their ends 38 (Fig. 6) and are connected together'by a cross-piece which is placed in metallic contact with the flanged part 7 of the core 7, for instance, by the angle piece 41.

Under these conditions the magnetic circuits are very numerous, and are closed as indicated by the arrows in Fig. 7. The magnetic fluxes traverse the type pieces 17 which are placed on the surface of the table so that the said type will adhere to the table properly.

By making bars373839 very thin, I

may obtain magnetic circuits which lie very close together, so that the magnetic field is uniformly distributed over the surface of the type carriage.

Obviously, the arrangement of the bars 373839 may be modified, and the bars may have an oblique or transverse position, or any'other suitable arrangements may be employed.

The plate may be composed of the bars 37 as shown diagrammatically in the end view Fig. 14 and in the planview Fig. 15. Said bars are made of a non-magnetic metal, of small cross section, and are connected together in any suitable manner, for instance at both ends and at the top and bottom by rods of a non-magnetic metal 38 which are inserted into the notches 37 in the said bars, as shown in perspective in the detail view Fig. 16, thus leaving a space 38" between the bars which may optionally be filled with brass strips, plaster, clay or the like. I prefer to place the said bars parallel with the smaller sides of the electric coil.

In the construction which is shown in Figs. 8 and 9, the core consists of several parts, three for instance, 7 7 7, eachiof' which is surrounded by a respective coil' 8 8 8. The said core maybe combined with a set of pole-pieces as shown in Fig. 2, or with a table comprising juxtaposed bars as shown in Figs. 8 and 9, or parallel bars as shown in Fig. 14.

The type pieces 17 preferably consist of one piece of cast or drawn steel, but they may be made in two parts, as shown in Figs. 10 and 11, and thus include a main portion 17 c of magnetic metal provided with flanges 17 between which I insert a metal of any suitable nature such as a type metal 17 the same being held in place by slightly upsetting the flanges 17 In the modification shown in Fig. 11, the piece of typemetal 17 is secured to the main body of soft steel by one or more which are fitted friction tight. 7

One advantage which is obtained with my said apparatus resides in the fact that the work may be corrected in a Very simple manner, for in the known methods of music printing it is a long and complicated matter to make such corrections. On the large-sized printed sheet obtained from the machine I may make all desired corrections by pasting upon any faulty notes or like characters, suitable pieces of paper containing the correct'characters, and since the sheet is photopins 17 graphed on a reduced scale, such corrections a separate process and then pasting the same upon the sheet of music before it is photographed.

Obviously, the said invention is not limited to the form of construction hereinbetore disclosed, which is given solely by way of example, but many modifications may be made ithout departing rom the spirit of my invention as comprehci'ided within the 'ZCOPG of the appended claims.
