Application filed November 19, 1910, Serial No. 593,20fi.

To @ZZ @IJ/wm t may camcom Be it known that I, kann Brown lLUGi-i, a citizen of the United States, residing at Chicago, in the county `oi" Cook and State of Illinois, have invented a certain new and useful Improvement in Mechanical Musical Instruments, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates 'to mechanical musical instruments and especially to a type of instrument commonly called a player piano or piano player.

rlhe present invention relates more particularly, although not exclusively, to the accentuation of certain notes or series of notes to bring out solo edects.

rlhe object of the invention, when applied piano players or player pianos, is to provide means for producing the aforesaid solo ejects in an improved manner. Certain broad features of the solo device vherein set forth are claimed in my copending application, Serial No. 554,140, filed April 8, 191.0.

I have shown in co-pending applications Serial Nos. 593,208 and 593,205, filed of even date herewith (Nov. 19, 1910), systems in which I use power pneumatics to operate the piano action, and supplemental means, prei'- erably in the nature of removable stops, to limit the stroke either of the piano action or the pneumatics, by the operation of which solo effects may be produced. Il`he supplemental means are preferably operated by what I term ,auxiliary or solo pneumatics, Both power and auxiliary or solo pneumatics are preferably under the control of the tracker board. In my present invention. I accomplish the saine or sin results by the use of what I term lresilient abutinents, against which operatiinel portions of the action act, and the control of these resilient. abutments by supplemental preferably in the form of solo pneuniatics, to thereby secure the solo effects as set forth in my aforesaid application Serial No.. 554,140. I

I will describe my invention more in detail by reference to the accompanying drawings, in which:

` mechanical means,

'Renewed c'ccber 1S, 1915.

enlarged detail view of the apparatus or' my invention as shown in Fig. 1; Fig Il shows a modification of the apparatus set forth in Fig. 3; Fig. 5 is an end view of the apparatus of Fig. el; and Fig. 6 is a detail view to illustrate more clearly the apparatus of ltigs. -land 5. I

Referring initially to Fig. 1, I show a musical instrument having strings 1 to be lstruck by a piano action :2

which may be under the control of a series of keys 3. its illustrating the invention, ll show arms s which likewise serve to actuate the piano action. to strike the strings 1.

The arms or members sl are actuated by power pneuinatics 5 which are controlled through suitable valve mechanisms '6, tubes T leading therefrom to the tracker board el at the openings 9. Supplemental or solo pneumatics 10 are controlledby valve mechanisms 11 which are connected by tubes 12 with the openings 13 in the tracker board. S.

. music sheet lil, having narrow openings 15 which cooperate only with the openings 9 and wide openings 16 coperating with both openings 9 and 13, is used to selectively control the actuation of pneumatics and 10 in accordance with the operation set forth in my aforesaid cti-pending application tassello.

A rail 17 is provided assliown, through which the rods 18 project. lhere is preferabiv one solo pneumatic 10 for each power pneumatic 5, and a single rod passing through the rail 1 7 is associated withy both of said pneumatics of 'that particular group or set. An arm a' is likewise associated with cach rod 18. blow, whena narrow' music sheet opening uncovers a tracker opening 9, and a power pneumatic collapses, in tie operation of the deyiceg. it acts against a spring 10 interposed between the arm 2G' the respective solo pneumatic 1.0 anl the are uncovered by awide opening 1c of music sheet 1/1 to cause the actuation of l vention, what I vso ` case with the construction set forth in nected to, said pneumatic,

4only the power pneumatic 5 of aigiven note,

downwardly so that, as the power pneu-l matic 5 collapses, a loud note is sounded, as the pneumatic 5, does not, in that case,have to operate against the full tension of the spring 19.

In the modification of the device set forth in Figs. 4, 5 and 6, the arm 20 has a forked extension comprising the prongs 21, 21 which restl on top of a washer 22, which washer is in association with the spring. In this form of carrying out the invention, the power pneumatic operates against the spring 19 but in this operation does not collapse the supplemental or solo pneumatic 10 as is the Figs.

1 and ,3.

The tracker board and music sheet disclosed herein are set forth nd claimedin a copending application of ine, Serial No. 554,142, filed April 8, 1910, tracker board and music sheet.

I Certain broader features of the invention herein set forth and claimed are also disclosed and claimed broadly in my copending application, Serial No. 598,203, filed November 19, 1910, mechanical musical instruments.

- While I have herein shown and particularly described the preferred embodiment of my invention., I do not mea'n to limit myself to the precise construction and arrangement as herein set forth, but
