AUTOMATIC MUSICAL INSTRUMENT.
Application filed November 5, 1918. Serial No. 261,239.
To all ii /101): may 507100771.
Be it known that 1 Josarrr TTU'NTLR DroniNsox a citizen of the l n w. States,
residin' Larchmont. New
' n new and useful Tim niatic Musical l This invention depends upon the discoverv that the average uninusical person playan automatic piano can readi y give a pleasingniusical interpretation of the solo notes the music-roll (l) by listen the d u musical expression giver tomatically or a skilled. 13813. nicr to the 'r accompaniment notes and sympathetically operating. a? he listens. the means which controls the dynamics oil the solo notes. The invent on rcsides in the combination of mean. by which the above discovery can be pract cally utilized in a working instrument.
The drawings show diagraiiuzaatically in F i 's. and 2 two of the possible embodists my invention is adapted to take. Fig. showing the preferred embodiment. The wings show the parts spread out diaw imatically with only the o 'icrativc connect ons between tliem indicated. but it will be understood that in practice they will ordinarily be compactly embodied in an operative manner in the piano. Also, no attempt has been made to show the p: is in their relative size or correct proportions. F 5 is a horizontal section partly in plan on the line 3-3 in Fig. 2 looking in the direction of the arrows, but the valve is shown partly open instead of closed as in Fig. 2.
1 designates the music-sheet of the automatic piano, 2 the usual tracker-bar supposed to have the usual note-playing ducts, 3 the automatic player action supposed to comprise the usual pouches ope 'atively related to the ducts of the tracker-bar. valves, striker-pneumatics and other parts well known in this art. Also, 4 is the usual pair of foot-pedals for operating the usual pair companiment notes are struck. The diagram shows a well known type of said bellows wherein 7 is a box having sides and a top with a port through it at 7* but having no bottom. 8 is an internal port controlled by the kniie-valve 9 inside the box 7. This port 8 is the mouth oi? a pipe or coupling which projects inwardly through the rear side of the box and at its other end is connected by tubing 10 with the reservoir 6. 11 is a rock-shaft projecting through a suitable bearing-opening in the front side of the box. Within the box it has a rigid crank-arm 12 pivotally connected to the heel of the valve 9. Outside the box it has a rigid crank-arm 13. 14 is a rod pivotally connecting said crank-arm 13 with the top board of the so-called accordion bellows 15, consisting of a plurality of separate bellows a, Z), 0, (Z, secured together in a stack one on top oi another. the bottom-board of the stack being secured to a fixed support said separate bellows having different extents of collapse. Tubing 16 and valve-boxes 17 operatively connectin well-known manner the tracker-ducts 2 2 2, and 2 respectively with the separate compartments. a, Z), c and (Z of the accordion bellows. The tension spiral spring 18 keeps the accordion bellows normally expanded as shown. It will be understood. that whenever music-sheet perforations 25 register with one or more of the tracker-ducts 2 to 2 the corresponding valves 17 are operated to cause the exhaust and collapse of the corresponding compartments a to (Z of the accordion bellows.
22 is a link connecting the toe of the knife-valve 9 with the movableb0ard 7 of the regulating-bellows. 23 is the usual regulating or expression bellows spring connecting the movable board 7 with a stationary part 24, said spring as usual belng an adjustable tension spring tending to open the bellows and also tending by means of the link 22 to swing the toe of the valve 9 downwardly so as to uncover its port 8.
19 is a tight box mounted on the box 7 divided into rightand left-hand compartments by a partition having a port 19 controlled by a flap-valve 20. 21 is a pipe which connects the player-action 3 with the left-hand compartment of the box 19.
From the foregoing, it will be seen that the player-action 3 is operatively connected port ction betwee 1 and e 1e ecr-aeiiie 'i'i'i'em mu. ie=

2. In combination with a. musical instrument, a music-sheet controlled player-m cion including; tracker-board; a music-sheet having dynamics-expression perforations related to one of a plurality of mu ical parts represented by music-perfo1utions in said sheet; an air-tension producer operatively connected with d action; means controlled from said expressionperforations tor varying the air-tension in the action. to sound the first-named musical part with musicsheet controlled dynamiz-s-exprcssion; and means control]. ole by the operator and operable to produce an air tension in the player action which is proportionally diii'erent "from that produced by the aforesaid music-sheet controlled means at the times when the respective music-perforations for said second part reach the tracker-board, thereby giving relatively different dynamics-expression to said second. part.
3. In a musical instrument adapted to be played from a music-sheet. the combination of a player action controlled by the musicsheet music-sheet controlled means for causinnthe player action to render one musical part of the composition with dynamics-expression which will constitute an aural guide to the performer in the rendition of the other musical part of the composition, and means controllable by the performer and capable of giving dynamics-expression to said other part of the composition as indicated by said aural guide.
4. In a musical instrument adapted to be p ayed. from music-sheet having note porforations for the solo and harmony parts of t e note l the comp 4 t ion producer i A I tr'uv related to a composition and also dynamics-expression erforations operatively related to the note 'foations for one of said parts of the composition, the combination of a player action controlled by the solo and hi aony note perforations of the music-sheet, means controlled by the dynamics-expression perforations of the musicsheet to give dynamicsexpression to the corresponding part of the composition and to thus produce an aural guide for the performer in rendering the other part of the composition, and means controllable by the performer and related t the note perforations for said other part only of the composition f r iving, at the will of the performer, dyn mics-expression 'd other part of the composition,

6. In a musical instrument adapted to play a musio sheet having solo and harmony note perforations and also dynamics-expression perforations related to the harmony note perforations, the combination of a player action, air-tension producer connected thereto, means controlled by the dynamicsexpression perforations for regulating the air tension in the player action for the playing of the harmony notes and to thus render the harmony With dynamicsexpression Which constitutes an aural. guide to the pertormer in the rendition of the solo, and means controllable by the performer for producing a relatively increased air tension in the player action for the playing of the solo notes only, as indicated by said aural guide.
7. In a musical instrument, the combination of a music-sheet having note perforations for the solo and harmony notes of a composition, the note perforations for the respective parts of the composition being differently arranged thereon, and also having dynarmies-expression perforations for one of said parts of the composition, a cooperative traoker board, a player action controlled by the solo and harmony note perforations of the music-sheet, an air-tension producer connected to the player action,
means controlled by said dynamics-expiression perforations for regulating the air tension in the player action, thus expressing; the dynamics of the part of the composition corresponding to the note perforations to which the dynamics-expression perforations are related and thereby providing an aural guide for the performer to follow in the rendition of the other part of the composition, and means controllable by the performer for producing relatively increased air tension in the player action at the times when the note perforations for said other part only of the composition, come into rep; ister With the tracker board, thus giving, at the Will of the performer, a distinctive dynamics-expression to said other part only of the composition, as indicated by said aural guide.
In testimony whereof, I have signed my name to this specification this 4th day of llovember, 1918.
