To all whom it may concern:

Bait known that I JHN W. DAnLEY, Jr., a citizen of the United States, residing at Baltimore city, in the State of Maryland,

have invented certain new and useful Im-- provements in Expression-Devices for Keyoard Musical Instruments; a'ndI do hereby declare the following to bee full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My pre'scntinvention relates to improvements in musical instruments, and it is in tended to provide dynamic means operated by a key, whereby one or more sound.pro-

ducing means may be 'sounded by single movement of said key, the particular sound producing means that is sounded,-or the number of said sound-producin means that are sounded being determined by the speed impressed upon the key by. the operator.

My invention is especially applicable to organs, harmoniums, or such.

of the same or diiferent timbre by a single movement of the key. In practice with organs this is now accomplished by means of a series of movable stops which have to be moved by hand from time to time, and interfere very materially with the laying of the performer, and also preclude t 1e possibility of producing. music having the va- 3 5 riety of expression of that produced on the ordinary piano forte. The device may also i be used to vary the force of the air applied to the sounding-means and change the pitch of the sound as well as'its loudness. The

40 invention may alsojbe adapted to striking one or more strings accordingto the will of the performer, and in fact, it"might be applie to a large number of instruments.

My invention is shown as applied to a grand organ. in which the velocity of movement of the key is caused to be the determining factor in selecting in electric circuit, the completion of which will"ope'rate one or more eds oipipes of the organ, as will be here-c .50 ihafter described.

Fig. 2 is an enlarged view of the inner end-of one ofthe keys, with the electric contact making device operated thereby, the key being in the position it takes when pressed 5 down by the player Fig. 3 shows a section along the line 33 of Fig. 2, looking down. Fig. 4 is a detail showing one of the electrical contacts. Fig. 5 is an enlarged view of a portion of the controller drum operated by the pedal, parts being broken away. Fig. 6 is an end view of the device shown in Fig. 5 as seen from the right of said figure. Fig. 7 shows the development of one of the units troller drum is at position number 1.

A represents a part of the frame of the keyboard, and A, A A A A and A represent rails extending across the keyboard at right anglesto the keys.

B re resents one of the keys which isof the usual orm, and weighted as at 1;. Near the inner end of the key is mounted an adjustable stepsil or capstan screw 1) which en-. gages the felt piece 0 secured on the arm O of the tee lever C, which is. pivoted as -at c to the flange ascrewed to the rail A. This tee lever C has an upwardly projecting arInC rovided with a pivot pin a for the finger D. his fingeris normally pressed outwards by means of the spring D, see Fig. 2, and carries. a padded pin or roller (1 which engages the wire F, fast to the key B., This-wire is bent laterally as at f to clear the tee lever C, and is then-inclined upwards as at f, and finally terminates in an arc shaped portion f which is concentric with the pivot center 0 when. the key is in the initial position, or before it has been struck by the player. The tee lever C. is normallydrawn downwards about its pivot c b means of the spring E which is adjusted y'means of the thumb t El I I g. I g H represents-one of a plurality of curved Fig. 8 is a diagram 75 its fin the-arc of a circle having as the center, as

Linsulating blocks to each of which the con- .tact pleces K and K are secured; These contact ieces are preferably fastened to the block H by means of the screws k and the binding screws k, to which latter the conducting wires are connected as shown in Fig. 1. The lower face of the block H is dentated shown in Fig. 2, and is faced with a felt or buck-skin strip h over'which project the contact faces k? of the. contact pieces K. The bottom contact piece K is provided with a contact face k.

- It will be noticed that the contact pieces K V do not extend radially inward as far as does the buckskin, and hence the finger D will not make contact therewith as the tee leverrises henceno pipe will sound .as the said lever rises. Thls is true also of the contact K, for

- known, is

when the tee lever Crises suddenly theinertia of the fin er D prevents it from moving outwardly wit sufficient rapidity to touch the contact K.

Only a slow rising of the .tee lever C, will cause the finger D to make contact with K. Asthe teelever C starts to descend the spring D brings the finger D swiftly into one of the notches h where it makes contact with the corresponding contact face 7c. It is intended'to have one block H, with itscorresponding contacts, and

i one tee lever and finger, for each key of the or an or other instrument. I

he energy of any moving mass as is well 1; w; sisted by a constant force the travel of the finger would normally vary as the square of the velocity at which the inner end of the key B swings upward, but by constructing the s ring E so that its tension varies :as its exure throughout 'its'rnovement, this motion upwards of the finger D may be caused to vary approximately as the velocity instead of as the square of the velocity, and therefore,

a series of equal ste s may be rovidedon the block H for the en d of the er to engage in when the tee lever has been thrown up under the influence of the blow given to the key. In the position shown in Fig. 2, the parts are in the position that they would assume when the key has been struck a moderate blow sufiicient only to throw" the tee lever up far enough to cause the finger to engage;

the third contact piece on'the block H.

the key were pressed down very softly by the player, the finger would make contact with .the lower contact face 70 on the contact piece K. If the key is struck a little harder, the finger would engage in the first tooth of the block H, while if it is struck quite hard,

the fin er will pass clear beyond the block,

and wil engage against the face 70 of the upper contact plece. Thus it will be seen that the finger may be thrown in any desired position by a performer, by simply striking the and if this energy were rekey with a varying: as ke s are struc y seen t at thenote'will be sustained as long as the finger is held in en agement with the contact iece for closing t e electric circuit, and the n er will so remain as'long as the key is presse j down by the layer. As soon as this key is released, owever, the inner weighted end will fall' of itsown weight, caus ing' the curved portion f of the wire F to strike the padded pin d, thus knocking the finger out of engagement with the contact piece a ainst the action of its spring 'D.

his wil break, the circuit, and the arts will be restored to the initial position.v hen the key is struck a ain, the curved portion f of the wire F will, swung clear of engagement with the finger v The wires 1, 2, 3, 4, 5,6, and 7 are connected to their respective contact pieces, and

then lead to sp 'ng contacts m to m respectively,see Fig, 5, which spring contacts press against the conducting rings pon the unit P- o carryin a pointer S, and this shaft carries a' pimon 2 engaging the'rack T carried by the rod T, which is operated by the edal T,

-which pedal is normally held'in t e raised osition by meansof the sprin T as shown 1n Fig. 6. It will be noted t at by simply press ng on the pedal T the pointer may be set to any one of eight positions. The arm S is thus caused to move over a, dial S for reasons hereinafter to be described. The electric current is carried from the battery N, or other source of electricit to the finger peed in the same manner pianists. It will be D by means of the wire n, an the other ter-' I minal of the battery is connected by the wire n to the spring contact m. The last contact segment p of each unit P of the-controller is adapted to make contact with a series of spring contacts 9., g g, etc., and isitself o t e connected by means .sprin contact m to one pole of the battery N. 0 these contacts, q and g, close the circuit through the first magnet 1 g and q close the circuit through the magnet 2 9 and g close the circuit through the magnet 3 etc. Each of these ma nets'operates anarmature 1", 2, etc., see 1 igs1, and this armaturewhen attracted to the magnet, operates a valve which admits air from the trunk O to the The corresponding ipe 1', 2, 3, etc.

trunk O is supp ied with air under pressure in any a proved manner, and the air 1s to be 1 admitte to thepipes 1, 2, etc., by valves operated by the armatures 1, 2, etc. in any lated from said rings, and said wires are bent "approved manner. -The means for supply ing the trunk with air, and the construction of'the valves -l'or the pipes not being a part of this invention willnot be further illustrated or described.

. The developmentof one of the units of the controller drum is shown in Fig. 7, the plates m, M28, m, m, m, m, and m7, being connected-by wires to the contact rings on which bear the springs m, m", m mt, m, m, and of, respectively, and also to the contact plates 9", 1 9 g, and g, respectively. The wiresby which these connections are made are sunk in'the insulating drum which supports the contact rings'so as to be insuradially outwards at the proper points and pass through holes in the-contact plates and rings and are soldered therein, and alter-.

wards cleaned oil" flush on the outside; These wires are represented in Fig. 7 by dotted lines terminating in a round dot,

which latter represents the soldered part. This is the well known method of illustrating the internal connections of a controller drum.

When thepointer S is on the zero mark of the scale S", the circuits will be arranged as in F ig. 8, the magnets being in parallel branches and itwill only be possible to sound one pipe at a time, the speed impressed upon the key by theoperator determining which pipe is to sound. For instance, if the key is slowly depressed, the finger D-will make contact with the contact piece K, and the pipe 1 will sound; if the key is depressed slightly faster, the finger D will makecontact: with the first of the series of contacts K, and pipe 2 will'sound. Still further increases in the speed of depression of the key will cause pipes 3, 4*, etc., to besounded, but at no time can any key sound more than one pipe at a time.

When the pointer S points to the division 1 on the scale S, the circuits will be arranged as in Fig. 9. The said pointer may-be moved toany position on the dial S by means of the pedal '1", and thus changes the arrangement of the electric circuits as will be hereinafter explained: thus it will be evident by referring- 'to Fig. 9, which shows the magnets in series that if the pointer is at the position 1 on the scale S, and if the finger D closes the circuit through the wire 1, the magnet 1 only will be energized and its corresponding pipe 1 Wl'l-l sound. If the finger closes the circuit through the wire 2, both of the magnets?- contact plates m to m will be central with theifirst dotted line to the right of said contacts: Then g still engages m but at its right hand side, Q22 to Q77 still engage the contact plates m to m" respectively but at will' connect together 9', g and m through the wires 9 and g, the rest of the contacts q to q, I to g and m? to m inclusive, being d together by similar wires, and g connects and m will be connected by the wire (,1 and as m which the contact ring p connects to.

q, .is connected by wire a with the battery, and as,thef connec'tions from m, m m m m, m, a'nd'm are connected to the ' wires 1, 2, 3, 4, 5, 6 and 7, respectively, and-as the connection to: the finger D remains unchanged, it is evident we have the scheme of connections shown in Fig. 9, which is obtained when the pointer is opposite 1 on the dial. The scheme of connections for theremaining positions on the dial is the same as for position 1, except that'the pipes are arranged to sound. in different groupings.

The connections for positions zero and 1 have been explained, and it will be remem-- bered that when thepointer is at position 1 that pipe 1 could either be sounded alone, or pipe 2, pipes'Z and 3 pipes 2 3* and 4, etc.', could be sounded slmultaneously with pipe 1, and thus a solocould be played onthe series of ipes 1, and the other pipes could be broug t into play as desired, to sound with the series of pipes 1*. By series of pipes 1, 2*, or 3 etc., is meantthe pipes of a certain tone'or timbre, one of which of the proper pitch is connected for operation by each key. Thus if the series of pipes 1 were the flute pipes, there would be'one of the proper, pitch for each key; hence if there were 88 keys inthe manual, it being remem manual is required, there would be 88 flute pipes, and a slow depression of any key would sound the flute pipe corresponding thereto; likewise the series of pipes 2 might represent the clarinet pipes, of'which there would also be 88, and striking the keys slightly faster the clarinet pipes could be sounded in unison with the flute pipes,a'nd so on for any number of pipes of diiTe-rent tones. I parts on different toned pipes would be desirable, the connections corres ondin to r the otherdial positions are provi ed, an the different combinations are tabulated below.

Now as the ability to play the solo 'bered thatwith this construction only one Position 0'. Either 1, 2 3*, 4 5, 6

or 7 a can be sounded, but only one at a time. Position 1. 1 solo; 2, to 7* sounding simultaneously. I i Y Position 2. 2 solo; 3 to 7 a and l soundin simultaneously.

v pipes made to come in'any. order desiredbaving the dial at theproper one of the pos :Positio'n solo; to 7jand. 1 t'0 sounding simultaneously. Position'5. 5 solo; 6' to multaneously. I. v

Thus it will be seen thatthesolo be played on any series of pipes 'and't e other- 'tions 1 to 7-, .;while by havmgthedial at posinumber of 4 vary'not on v the loudness of thetone, but

"tion 0, the solo partcanbe played on any "series of pipes, the series bemg dependent upon the speed with which the key is tie--- presse'd.

While I havestatedthatthe i es for-each key have the same pitch, but erent tii'nbres, I have merely mentioned this as' the ordinary construction for special cases the Q instrument may be constructed so that the n first pipe to sound would be the fundamental: tone forthat key;'by'strikin thekey'slightl harder the next pipe wo d sound,-swhic' could be-the fifth-above thefun'damental' *toneybut of the same timbre, and so for. the other pipes for that key which could give;

tones thatare upper-partialsof the funds mental, and so alter, by vmerely changing the speed with which the key is struck, not only t e volume of sound, but also its timbre.-

. Moreover, while I have shown seven pipes for each key, the number of these' pipes may teeth on thesector H being corres ondin 1y varied, the only limitation being t e ability of the operator to differentiate by his touch.-

'Thus it will be seen that azsingle edal maybe used to control the tone, an .each key may be 'used to sound either a singlepi e or a ipes simultaneously an thus' also its quality. .This invention, therefore, when applied to organs does away with'a large number of stops, pedals, and other devices used to control,the expressiomi but; which do not give the performer the ability to 'roduce the efie'cts 'due to' sudden or gra ed differences in the loudness or timbre of tone.

While the apparatus is illustrated as applied to an organ, it 'be' obvious .that a': fing'ermay be operated-by a key, and control.

It Wlll furthermore be evident that the finger may be used to oper-" ate pneumatic valves, 'which pneumatically control pipes or reeds of organs ,or strings of instruments or other like musical devices .I do not meanto limit my invention to the specific form of device, or to the application of the finger for closin electric circuits, except when so spe-Q cifica y stated in the claims.
