To all 't0/ wm t may concern.'

Be it known that l, FRANK B. Lone, a citizen of the United States, residing at Los ngeles, in the county of Los ngeles and State of California, have invented certain neu7 and useful i iprovements in Player- Pianos, of which the following is a specification, reference being had therein to the accompanying drawing.

r:the Object of the invention is to provide a new and improved player piano arranged to permit of playing it by hand in the usual manner or playing' it automatically by the use of a note sheet and with the melody or the music in clear distinction to a subdued accompaniment.

in order to accomplish the desired result, use is made oiC soundinfr devices and automatic means for actuating` sounding; device to produce a normal sound while actuating another sounding` device in subdued rela-- tion to the rst-named sounding device.

A aractical embodiment of the invention is represented in the accompanying drawings forming' a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the Views.

Figure 1 is a cross section of the player piano;

Fig. 2 is an enlarged cross section oiz a portion of the same;

Fig. 8 is a side elevation of a modified form of the controlling means for the hammer rail sections;

Fig. d is a faceA View or1 a portion of the note sheet; and

5 is a sectional plan View of the se on the line 3-3 of Fig. 2.

The strings 6 of the piano are adapted to be sounded by hammers 7 normally resting on a. hammer rail made in sections 8 pivoted on a rod held on a supporting' rail 9 mounted on links fulcrumed on brackets 10 fixed on the piano frame 11. Each hammer rail section 8 has its rear tace provided with a felt cushion 82 and each hammer rail section is of a width to accommodate one or more successive hammers 7 preferably, however. three hammers, as shown in Fig. 3. `Each or" the hammer rail sections 8 is pressed rearwardlj,Y into haltstroke position by spring 1 prei'erably attached to the back of the supporting rail 9 and bearing' with their` free ends on the bottom of a recess formed in the front face of the corresponding hammer rail section 8. ln order to move any one of the hammer rail sections into ull stroke position it is necessary to swing the said hammer rail section forwardly until the front face of the hammer rail section abuts against the back of the supporting rail 9, as will be readily understood by reference to Fig. 2, which discloses one hammer rail section 8 in half-stroke rearward position and another hammer rail section in retracted forward position. Normally, the iammer rail sections 8 are in half-stroke position and whenever it is desired to emphasize a particular note in the melody when the corresponding' hammer rail section is retracted to full stroke position to allow the corresponding' hammer to sound the string with full :torce in contra-distinction to the sounding` of the. strings by the hammers 7 which are in half-stroke position and produce but a subdued accompaniment.

In order to move the hammer rail section 8 into retracted full-stroke position, use is made of pneumatic-s 14 mounted on a wind chest 15 and having` their movable members connected by strings or other flexible connections 16 with hammer rail sections, the flexible connections 16 extendingl through suitable guideways 9 arranged on the supporting' rail 9. The wind chest 15 is mounted on the piano frame 11 and is connected by tubes 1T with tracker board openings 18 of a tracker board 18, over which passes the note sheet 19 in the usual manner. The tracker board 18 is provided with the usual tracker board openings 2O adapted to register with the note sheet openings 21 for controlling the striking movement of the hammers 7 as hereinafter more fully explained, the note sheet also having supplementary note sheet apertures Q2 adapted to register with the tracker board openings 23 whenever it is desired to retract a corresponding hammer rail .section 8 for the purpose above eX- plained. The supplementary note sheet openings 22 are preferably arranged along the side edges or borders of the note sheet 19` In practice it is only necessary to employ about sin pneumatics 14: for retracting a corresponding number' oi? hammer rail sections 8 to accentuate the melody of an ordinary piece or music, it being understood that six retracted rails accommodate eighteen successive hammers, say, of the middle portion of the piano action, as indicated in Fig. 3.

The hammer rail sections 8 when in halfstroke position rest on a rod 24 mounted on arms 25 fulcrumed on a rod 26 held on the bottom of the supporting rail 9, and one of the said arms 25 is provided with a depending arm 27 pressed on by a spring 28 and engaged by an eye 29 on the movable member of a pneumatic 30 mounted on the wind chest. The pneumatic 30 is connected by a flexible tube 31 with another supplementary tracker' board opening 32 adapted to register with a corresponding supplementary note sheet opening 33 of a length corresponding to the note sheet openings 22 for the melody to be emphasized at the time. It is understood that as long as the note sheet opening 33 is in register with the tracker board opening 32 the pneumatic 30 is held in collapsed position and consequently the rod 24 is in rearmost position with the hammer rail section 8 in rearward half-stroke position by the action of their springs. It is further understood that during this time the hammers 7 are held in half-stroke position except those abutting against a hammer rail section 8 retracted by the corresponding note sheet opening 22 registering with a tracker board opening 23. When a nete sheet opening 22 is in register with a tracker board opening 32 then one or more regular note sheet openings 21 are in register with the corresponding tracker board openings 20 to cause the hammers in full stroke position to sound the corresponding strings 6 while the accompaniment is played bv hammers 7 in half-stroke position. When the note sheet opening 33 has moved out of register with the tracker board opening 32 then the pneumatic 30 is infiated and the spring 28 now imparts a return swinging motion to the arm 27 and consequently to the arms 25 to move the rod 24 forwardly and thereby swingingr the hammer rail sections 8 from half-stroke position into fullstroke position, and the remainder of the music is executed with the hammers at fullstroke position unless the hammer supporting rail 9 is swung rearwardly to move all the hammer rail sections 8 into half-stroke position. v

The regular tracker board openings 20 are connected by flexible tubes 34 with pneumatics 35 preferably in tiers and mounted on the piano frame 11, each movable member of a pneumatic 35 being connected with a corresponding wippen 36 by a lifter rod 37. Each wippen 36 forms part of the usual piano action and is connected in the usual manner with the hammer 7 so that when a note sheet aperture 21 register-i with a tracker board opening 20 then the corresponding pneumatic 35 is actuated to impart a swinging motion to the corresponding hammer 7 with a View to sound the corresponding string 6, it being understood that this action takes place whether a hammer is in half-stroke or in full-stroke position.

In order to permit the player to normally move the hammer rail sections into halfstroke position, use is made of the usual soft pedal connected with a lever bar 38 engaging the supporting rail 9 to swing the latter rearwardly whenever the soft pedal is pressed.

Instead of using the pneumatic, 30, tube 31, tracker board opening 32 and note sheet opening 33, use may be made of an arm 40 (see Fig. 5) under the control of the player and mounted to slide transversely on the piano frame preferably at one side thereof. The rear end of the arm 40 is connected by a pin 41 with a slot 42 formed in the lower end of an arm 43 which takes the place of the arm 27 previously mentioned. Thus when the arm 40 is pushed rearwardly a forward swinging movement is given to the rod 24 so as to move all of the hammer rail sections 8 into retracted position against the back of the supporting rail 9. A spring 44 presses against the under side of the arm 4() to hold one of a series of notches 45 formed in the top of the arm 40 in engagement with a fixed pin, 46 on the piano frame. The forward end of the arm 40 is preferably provided with a knob 47 under the control of the operator to enable the latter to move the arm 40 rearward or forward for moving the arm rail sections 8 from half-stroke into full-stroke position or allowing the arm rail sections to return from full-stroke position to half-stroke position by the action of their springs. The arm 40 is held in a desired position by one of the notches 45 engaging the pin 46.

The operation is as follows:

lVhen the instrument is played by hand the hammer rail sections 8 are held in forward position against the supporting rail 9 by the rod 24 pressed forward by the action of the spring 28 which latter is sufficiently' strong to overcome the springs. All of the hammers 7 are now in full stroke position and when the keys are played the hammers sound the corresponding strings according to the touch of the player and if it is desired to execute pianissimo passages of music the soft pedal is pressed to swing the supporting rail 9 and with it the hammer rail sections 8 rearwardly into half-stroke position.

It is understood that when the piano is played by hand the pneumatics 14 and 30 swe in inactive inflated position and the flexible connections 16 are slack (see Fig. 1).

l,When the piano is played automatically with the use of a note sheet 19 then the pneumatic.30.-is deflated orfcollapsed wheneven the note sheety opening -33 is in register WithQthetracker board-aperture 32 so that the. rod 24 is swung rearwardly to allow .all of the hammer rail sections 9 to swing-rearwardly into. half-stroke position, such rail sections 8 being held in full stroke position whenever the pneumatic 30 is inflated with the'note sheet closing the tracker aperture 32, as shown in Figyl. As soon as one of the melody notesheet-openings 22 registers with; its corresponding trackerv board opening 23 then the-corresponding hammer rail section 8 is retracted into full-stroke positionlandv at about the same time a note sheet openingfQl. moves in register with its tracker hoard` opening 20 to cause the corresponding pneumatic ische-actuated.- When this takes place the corresponding hammer is thrown rearward to sound its string. Any other tracker board opening21v thatzmoves in register with the vcorresponding tracker board openings causes actuation of the corresponding hammers- -but as the latter are in half stroke position it is evident` that subdued accompaniment sounds, are produced 1in: .coni tradistmction to the loud sounds ofj-.thef

melody.-
