PIANO-PLAYER MUSIC AND MACHINE FOR PRODUCING SAME.

Application filed August 23, 1920. Serial No. 405,421.

(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. In, 1313.)

To all whom it may concern:

Be it known that I, REGINALD REYNOLDS, A. G. S. M., a subject of the King of Great Britain and Ireland, and residing at 3%, The Crescent, Barnes, London, S. W., England, have invented certain new and useful Improvements Relating to Piano-Player Music and Machines for Producing Same (for which I have filed an application in England Oct. 31, 1918, Patent No. 134,324), of which the following is a specification.

This invention relates'to improvements in music rolls hereinafter referred to as music sheets and their methods of manufacture. Music sheets as at present produced have usually a tempoline for the guidance of the operator in using the tempo lever. They also have an expression mark of an easily distinguished character for guidance as to the magnitude of the sound roduced. These markings, even'when applied at the same time, are usually placed on each music sheet individually, or in groups of sheets, say a dozen at a time, but their accuracy depends on the individual care taken in setting and in controlling the marking devices, these operations being done by hand. It will be seen therefore that considerable differences will occur in different sheets of the same batch, while different batches will dider still, approximation to ac.

further, and any real curacy is precluded. This is believed'to be one of the principal reasons why it has not feasible to apply markings a, corresponds to a definite mark of expreshitherto been such as bar lines to roll music.

It has been proposed to provide a pneu-: matically actuated means for printing ex-.' pression markings and a tempo line com-- prising a number of dots. By this proposal a master roll is furnished with certain series of perforations which control the action of the printing devices operating in connection with the music sheet, but since the drums upon which both the master roll and music sheet are fed forward are geared mechanically together, the positioning of the markings on the music sheet is liable to occur due say to the 'inequality between the natural strength in the paper forming the master roll and that forming the music sheet.

The objects of the invention therefore are to secure accuracy in the expression and desired to be the individual sheets,

considerable inaccuracy 1n:

other markings, and to enable bar lines and other markings to be applied accurately.

The invention consists in a piano player music sheet upon which markings are automatically placed in definite longltudinal positions relative to a series of marginal perforations in the music sheet.

The invention also consists in a marking machine including a marking roll and a music sheet the feed of each being independof the separate specially prepared marking roll a, which carries a number of series of marking perforations which are adapted to register with tracker bar ducts controlling marking mechanism, and in addition carries a single series of marginal perforations 8 adapted to effect the required synchronous movement in conjunction with the marginal synchronising= perforations't on the music sheetb. Each series of perforations provided in the specially prepared marking roll sion which it is desired to imprint, say in typewritten characters, to the music sheet I). Only a single perforation of one of these series is however shown (at 35). The special-marking roll a is unwound from an upper roller 0 on to a lower roller cZ,the two being suitably driven through gearing indicated at c operated from a pneumatic motor or other suitable moving device The music sheet 5 can be similarly driven by a motor 9.

The inlet to the motor f which governs its operation is connected by way of a pipe h to the valves 2', j, resting on pneumatic cushions m, a, respectively. The cushions m and p lead by way of the pipes q and 9" to ducts in the tracker-bars corresponding to the marginal perforations s and t in the roll a: and music sheet 6. The cushions a and 0 lead to the valves a and o in a supplementary valve chestw to which suction is applied by way of the pipe 00.

The valves u. and o rest on pneumatic cushions in connection with the pipes y and a leading to a motor controlled or bellows chamber 1 which is in communication with the chest 2 (carrying the primary valves 2' to Z) by way of suction pipes 3 and 4:. The pipes 3 and .2 terminate in a block 5 car rying a light spring controlled valve 6 adapted to be moved by a plunger 7 on the upward travel of a bellows plate 8 which is moved against the action of a controllable spring 9. The valve 6 on being raised by the plunger 7 permits air to enter pipes 3 and a and raise the valves a and q; thus putting the cushions n and 0 in connection with suction pipe 00. The valves to and '0 therefore when in the position shown in the drawing allow valves j and 72 to close and when in the raised position allow these valves to open by the deflation of cushions "/1, and 0. The governor I serves to regulate the speed at which the motors f and g operate since by variations of the tension of the spring 9 upon the bellows plate 8 the degree of suction required to raise the bellows plate 8 is varied. This plate 8 also carries a spring catch 10 which on being raised operates momentarily a cut out valve 11 and permits air to pass through a pipe 12 leading to pneumatic cushion 15 in connection with valve 14 in a valve chest 13. This valve 14 when occupying the position shown, puts the pipe 17 into communication with the atmosphere but when it is raised, it puts the pipe 17 into communication with the interior of valve chest 13 under suction through the pipe 16.

and thus effects deflation of cushion 19 and dropping of the valve 20. The main suction orifice 35 in a tracker bar 29 under the rolla. The pipes 16, 21 and 0c are in communication with the bellows chamber 31 by means not shown. Thus, the effect of raising the cut out valve 11 is to place the type operating valve chest 23 in communication with the main suction chest 18 which com munication is cut off immediately the valve 11 again closes the pipe 12. It will be noted that the catch 10 operates the valve 11 before the plunger 7 has operated the valve 6; the object of this arrangement will be explained below.

Power is primarily applied to the apparatus from an electric motor 30 driving blowing feeders 31 controlling a reservoir 32 and is transmitted to the motor 9 by way of a pipe 33 leading to the motor control ten-ding to lift the bellows plate 8 against the action of the spring 9.. It is also applied by way of the pipe 3, valve z' andpipe /L to the motor causing this to operate and to rotate the roll (1 until a perforation 8 comes over the end of the is then open to atmosphere. and the pipe 3 still being under reduced pressure, the pneumatic cushion m is distended, raising the valve 2' andclosing the aperture above it.

At the same time the cushion at is distended because the connection to the valve a is open to atmosphere, thus, both valves 11 and j being raised, the inlet to the motor f is closed and the motor stopped. Similarly the motor 9 is caused to rotate through suction.

applied by way of the pipe 3 1 untilan aperture 2% in the roll 7) comes over the end of the pipe 7" when the motor 9 is stopped also. The stopping of the roll a and chest 6 is therefore determined definitely by the mar-,

ginal perforations s and 2? respectively and is entirely independent of any unequal stretch in the paper comprising the marking roll and various music sheets. The tension of the spring 9 is so adjusted that it prevents the plate 8 being raised until a degree of suction resulting from stoppage of both motors is attained. Now as to the marking on the roll 5 corresponding to the. marking on the roll a, both motors having stopped in synchronism by means of the perforations s and 2? as explained above, the plate 8 is raised. and the catch 10 lifts thevalve 11 momentarily there-by putting the valve chest 23 in communication with main suction pipe 21. No effect however, is produced upon the valve 25 unless an aperture in the roll a is at the time registering with an opening in the tracker bar 29. In the illustration, only one opening 35 is shown to which the pipe 28 communicates the other end of this pipe leading to the cushion 24 of type mechanism 27 but as explained above, a number of series of such openings, pipes and type mechanisms are employed according to the different markings required on the music sheet. Assuming a perforation in the roll a is registering with the opening 35 during the time the valve chest 23 is in communication with the pipe 21, then the cushion 24 is inflated and the operating means 26 momen tarily is placed in comn'iunication with the main suction and will effect the typing of the necessary characters upon the music sheet. Further movement of the plate 8 pipe 9. That pipe Ill causes the plunger 7 to lift the valve 6 and cause the valves 7' and is to drop and effect re-starting of both motors.

When electric operation of the marking machine is utilized the current may be made to depend on contact taking place together through both sets of perforations.

In some cases there are available margins of unperforated paper in existing music sheets and I may in some cases provide in these margins a number of series of perforations each corresponding to one of the required markings. In such cases the music sheet itself operates the stamping machine so constructed that the passage of each of these new marginal perforations shall pneumatically, mechanically or electrically cause a particular stamping or printing elementinstantly to come into contact with the paper of the music roll, thus printing, marking or perforating the desired indications of expression, and also the bar lines, in the precise relative position on the music roll to that in which they occur in the corresponding ordinary music. The series of marginal perforations are incorporated in the original master roll from which all the music rolls of the particular composition are reproduced, and thus uniform accuracy is attained in the marking of each music roll.

It will be appreciated that according to this invention the marking of each particular character takes place upon the music sheet always in a definite longitudinal position relative to the marginal perforation therein. The markings therefore are definitely located in relation to the variation in the rendering they are intended to indicate. The markings preferred are eight in number 'l. p; 2. f; 3. Hall; 6. accel.; 5. tempo; 6. '5 (pause); 7. A (account) and 8. a bar line.
