HEINRICH BOCKISCH, DECEASED, LATE OF POUGHKEEPSIE, NEW YORK, BY GEORGE W. GITTINS, ADMINISTRATOR, OF NEW YORK, N. Y., ASSIGNOR TO XVELTE-MIGNON CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.
AUTOMATIC MUSICAL INSTRUMENT.
Application led April 21, 1920.
To all whom t may concern: n Y
Be it known that HEINRICH BooKiscn, deceased, late a citizen of the Republic ot (hecho-Slovakia, and formerly residing at Poughkeepsie, in the county of Dutchess and State of New York, United States of America, invented certain new and useful Improvements in Automatic Musical Instruments, of which the following a specitication.
This invention has relation to musical instruments ot' the kinds or styles provided with a plurality of sets, registers or scales of tone elements, each set having a different quality of tone from that of every other set in the instrument. It more particularly relates to stop mechanisms for such instruments. Organs furnish a leading example oi? :instruments of the kind or style ret'erred to and accordingly this invention will be described as applied to organs, but it will be understood that this particular application oi" the invention merely exemlnary.
It .is well understood that in a pipe organ the severai sets of pipes-constituting sets of tame elements-are connected to wind passages, respectively, each passage having a stop valve which is opened to admit pressure to the several pipes constituting the connected thereto, and that in the 'numanly played organ these valves are opened and closed by the manual manipulation ot elements which are arranged adjacent the keyboard and are commonly called stops and are so designated in the present aplilication. In other words, whenever the term "stop is employed in the following description and claims it will be understood to refer to one ot' these elements which in the humanly played organ is manipulated by the performer to render a set of tone elements operative or inoperative, and not to the set -ot pipes itself.
(lne ot' the important purposes ot' the present invention is to provide a means 'whereby a stop ot a musical instrument may be moved under control ot' a record to its yon and oil positions to thereby render the corresponding set of tone elements operative andL inoperative respectively.
Another et the import-ant purposes ot the invention is to provide a manually operable stop with means whereby it maybe also operated under control ot' a record.
Serial No. 375,576.
A further important purpose of the invention is to provide means whereby a plurality ot stops may be selectively operated by record-controlled impulses of diiferent characteristics to render the corresponding tone elements operative alone or together, and which record-controlled impulses of different characteristics t'or a portion ot' their course travel a common path, thereby substantially reducing the width of the record which would otherwise be required to control the operation of the stops.
These main purposes of the invention, and others which. will be understood without particular mention, are well secured from the construction in the accompanying drawings exemplifying the preferred embodiment ot the invention.
In said drawings, wherein like characters of reference denote corresponding parts in the several views F ig. l. is a diagrammatic view illustrating a very desirable embodiment of the invention, having two stops A and B, and showing the stop A in its on position and the stop B in its otl' position.
Fig. 2 is a det-ail view on a larger scale than Fig. l, showing the stop A in its off position, together 'with a motor tor operating said stop and the connections between the motor and the stop.
Fig. is a detail view illustratingthe stop B in its on position, together with its motor and the connections between it and the motor.
I have considered it to be unnecessary to illustrate thesets ot tone elements, or the stop valves, or tone valves, with the wind passages to which the sets ot tone elements and stop valves and tone valves are connected, as these may be of ordinary character, such as are well known in the art. In a coinpanion application, executed oli even date herewith Serial Number 375,575, to which in many respects the presentinvention is subsirjliary, Ihave .illustrated one ordinary arrangement of sets of tone elements with stop valves therefor, resliectively. Relierence to that application maybe had if necessary for a disclosure ot one arrangement ci such elements and valves which may he employed.
A and B designate two stops. It will be yunderstood that in' practice there .may be any number of these stops. In such case it would be necessary only to duplicate the mechanism illustrated and hereinafter described. It will also be understood that, in practice, the stop A is connected with a stop valve (not shown) to open and close the same to control the pressure to a wind channel to which a set oli tone elements (not shown) are connected so that the elements are operative when the valve is open and inoperative when the valve` is closed, as is customary. It will further be understood that, in practice, the stop B is connected with a second stop valve (not shown) to control the pressure in a second wind channel (not shown) to which a second set of tone elements (not shown) are connected.
The stops A. and B are capable of both manual and automatic manipulation, individually and together, whereby the' stop Vvalves similarly may be controlled either manually or automatically.
The stops which I prefer are pivoted at a and Z9 respectively. The connections between the stops A and B and the corresponding stop valves are preferably each of electro-pneumatic nature.
The accompanying drawings illustrate suitable connections of said nature, but connections of other construction and nature may be employed. The one illustrated between the stop A and the corresponding stop valve comprises a contact element 10 movable with said stop, and adapted to bridge the space between two contact members 11 and 12, and to thereby close an electrical circuit, hereinafter traced, which includes an electro-magnet 13 whose armature 14 opens and closes an atmospheric duct 15 which entends to a chamber 16 in a member C which controls the tension of the air within a pneumatic ymotor D whose movable board cl is connected to the corresponding stop valve by a link CZ. rIhe connection. between the stop B and the corresponding stopl valve is of similar character, said stop having a contact member 17 to bridge the space between two contact members 18 and 19 to close a circuit through a magnet 2O whose armature 21 opens and closes an atmospheric duct 22 which extends to a chamber 23 in a member E` which member controls the tension of the air in a pneumatic motor F whose movable board is connected to the corresponding stop valve by a link j. rlhe motors D and F are provided with springs cl2 and f2 respectively, `for expanding them when the tension of the air within and without the niotors is equal to each other, or, in other words, when both the inside and outside pressures are atmospheric, for example. Stop A has a rearward projection c and stop B has a similar projection o. These projections cooperate with the walls a2 and b2 in the board A2 of the console, to limit the pivotal movements of the stops, said walls preferably having facings of felt or other suitable material to deaden the sound resulting from impact of the stops therewith.
The member C comprises, in addition to the chamber 1.6, a suction channel 2er which is connected to chamber 16 by a bleed hole 24s, and is separated therefrom by a membrane 25, a valve chamber 26 having a suction port 27 and an atmospheric port 28, and a valve 29 in the valve chamber, provided with a stem 30 in operative relation with the membrane 25. A duct 31 extends 'from the valve chamber 26 to the motor D.
rlhe control member l@ is of like construction: 32 being its suction channel; 32*L the bleed hole` 33 the membrane; 3e the valve chamber; 35 and 36 the suction port and atmospheric ports, respectively; 37 the valve `in said chamber; and 88 the valve stem. 39
designates a duct which extends from the valve chamber 3a to the motor F.
lt will be apparent, that it either stop be turned pivotally to its on position, i. e., in the direction which closes the circuit through the corresponding magnet., air at atmospheric pressure will be admitted to the chamber 16 or 23 ol the corresponding member C or E, thereby causing the valve, 29 or 37, ot said member to move and uncover suction port 27 or 35, and close atmospheric port, 28 or 36, and that this will result in the collapsing of the corresponding motor D or F and the opening of the corresponding stop valve. lt will also be understood that if either ol the stops is moved to its off position, thereby breaking the circuit to the corresponding magnet 13 or 20, the reverse operation will take placeq namely, communication o air at atmospheric pressure with chamber.' 16 or 23 of the central member corresponding to the stop which has been thus moved, will be cut oli the valve 29 or 37 of' said n'iember will be moved to close the suction port and open the atu'iospheric port of' the lcorresponding central member, thus admitting air at atmospheric pressure to the corresponding motor D or F, whereupon said motor will be expanded by its spring (Z2 or f2 and in expanding will close the corresponding stop valve.
In Fig. 1, stop A is shown in the position it occupies during the first named operation, that is to say, when it is completing the circuit to magnet 13, and stop B is shown in the second named position, namely, when the circuit to magnet 20 is broken. lt will be understood that when the parts are in the position illustrated in this ligure all of the tone elements of the set controlled by stop A are operative and that any of them will speak, when the corresponding tone valve (not shown) is opened either by pressure upon the correspondingikey, as when the instrument is being played mannallji. or under Y llo \ control of a record when it is being played automatically. With the stop B in the position illustrated none of the sets of tone elements controlled therefrom will speak because the stop valve controlling the pressure of the air in the wind channel to which said tone elements are connected will be closed.
These stops A and B and the connections thus far described between the stops and stop valves are well adapted for manual operation, as will be apparent, but in order that they may be also adapted for automatic operation, i. e., under control of a suitably prepared record, the invention broadly contemplates mechanism for moving the stops in cluding connections which in either movement of the stop (i. e. to on or olf position as the case may be) are set into position to move the stop in the opposite dlrection. In the practical embodiment of the invention it is preferred to provide for each stop, a. motor and connections between the stop and motor, so organized that the stop will be moved to on and off positions by successive operations of the motor.
In practice, each stop is preferably under spring tension tending to hold it yieldably in either of its extreme positions and the connections between the respective motors and the corresponding stops are such that each connection is adapted to throw the corres pending stop first to one position (as its on pmzition, for example) and then to its other position (as its oil position, for example) by successive operations of the motor. I am aware that connections other than the partieular ones hereinbefore described may be employed between the respective stops and stop 'valves and further that even .if the connections` include electric circuits provided with circuit making and breaking elements which iuove with the stops respectively, it is not essential to the invention, considered in its broadest aspects` that the arms 10 and 17 projecting rearward from the respective stops A and B, to bridge the space between the contact members 11, 12 and 18, 19, respectively, be employed. However, such contacts are advantageously employed,` inasmuch as 'the contacts 10 and 17 may be pivoted to the respective stops A and B eccentric to the pivots a., b, of the latter, and the the contacts 12 and 19 may be resilient and constantly engaged with the otherwise free ends ol" the contacts l() and 17, thus utilizing said Contact elements 10, 12 and 17, 19 for the performance of a. dual function, namely, firstly, as contacting elements of a switch and, secondly` as means by which the stops are vieldably held in their extreme positions.
Moreover, I am aware that the motors employed to operate the respective stops may be ot' any suitable nature, pneumatic or otherwise. without departing from the spirit of the invention considered in its broadest aspects, yet it is preferred to employ motors of pneumatic nature, such as the bellows A and B shown in the drawings, and to connect the movable board of each of said pneumatic motors with the corresponding stop A, B, by jointed links. Thus the motor A is shown as having its movable board connected to stop A by connected links 40 and 4l,the link/lt) being pivoted at 40 to an arm (1.10 carried by the movable board of the motor A and the link 41 being pivoted at 41b to the stop A, and the motor is shown as having its movable board provided with an arm Z110 to which one end of a link 42 is pivoted, at 42a, the other end of the link being pivoted to a second link 43 whose opposite end is pivoted to the stop B at 43a. The stop A is provided with two spacedv shoulders 44 and 44a arranged on opposite sides of the link 41 and the stop B is provided with spaced shoulders 45 and 452l on opposite sides of the link 43. Each of these shoulders is preferably faced with a soft material to deaden sound. The link 41 is under tension of a light spring 46, Fig. 2, and the link 43 is under tension of a light spring 47, Fig. 3. One end of each of these springs is connected to the adjacent stop. These springs operate to throw the respective links 41, 43 oil'l dead center position with relation to links 40 and and the respective stops A, B, during the movements of the stops between their on7 and off positions. The link 41 oscillates between the shoulders 44 and 44a and engages the same alternately to throw the stop A into on and off positions by successive collapsing movements of the u'iotor A, and, similarly, the link 43 oscillates between the shoulders 45 and 45a and engages the same alternately to throw the stop B into on and off positions by successive collapsing movements of the motor B. ln the manual operation of either stop, the stop moves relatively to the link and the latter is not brought into contact with either shoulder on the stops,
lt will be understood that when either stop is in off position the corresponding contact member 10 or 17 will be out of contact with contact member l1 or 18 and hence the ciri cuits to corresponding magnets 13 or Q() will be broken` and that if either of said stops is now moved to its on position, either 'manually or automaticallv the corresnonding' contact member l() or 17 will be brought into Contact with Contact Aicnibm il or 18 and will thereby complete the circuit to the corresponding magnet or 20.
The operating p rt of the stops are so correlated that the r: .l 1l A stops may be effected Mithout meeting or otherwise disturbing the record controlled means, the connections being such that after an operation by hand. a subsequent operation by the record controlled del tl() ',.f'on of the it vice will always operate the stop to theopposite position. For this reason., care should be taken to have the stops in the oit position' be'ore any ieee involw'ing` the record control ot the stops, is played automatically. Or it the stop is moved to its ont position, by the operator who Wishes to introduce the eilect ot the stop Where it is not called for by the music7 care should be exercised to see that it ie moved to its off position before the nekt automatic operation i the stop occurs. 'lhe contact member l2 pressinn on the arm l0 is so arranqed that its point of contact with the arm is in a line perpendicular to the stop board face and which passes through the axis ot the stop. rlhis construction maintains the stop in one ot its extreme positions except when the stop is beingn moved. The connecting links Ll() and from the motor are maintained nearly1 in alinenient with each other by the resiliency ol' the motor spring m. The small spring et, however exerts a side torce on the links between their ends and forces them in the direction of the side toward v'i'liich movement will take place in the next operation of the stop. The small spring i6 being;- mounted on the stop and eccentric to its pivot, is moved each time the stop is moved by manual or record controlled means. l other end being connected to the links. as the stop end is moved to one side or the other oit the links, this small spring;` 'forces links away troni its stop end thus placinga the links in set position to permit the motor to opera-e the stop the next time the power applied to the motor and in a direction oiiposite to the last operation.
lilhcn p .ver is applied to the motor the link l0 is pressed toward the stop. rlhis movement si lgs the other link il upon its pivot and causes the saine to engage the shoulder ifi or del of the stop. Further movement of the motor causes the stop to move until the pivot of the arm l() passes beyond the line between the point of contact ot the contact spring l2 and the pivot of the stop. The spring contact member l2 non.T presses the arm l0 which in turn Piorces the stop to its other limit. is the motor releases the compression in the link l0, the links come hack to alinement. This is caused by the action oli the motor spring m drawing out on the link i0. its the links approach a p0- sition in alinement. the small spring 46 tierces the connecting point otx the links over` the center and in position to operate the stop in the opposite direction when the motor is or in operated.
flach time the stop is operated Whether by lio-f l 1- la' *Il v fl t" und t 't anc oL o5, 1e iecolL conne e motor, i either makes or breaks the circuit to the magnet 3, depending upon the direction in as hereinafter which the stop is operated, more fully explained.
The motors A and lt. are operated by mechanism which selectively utilizes suitable record-controlled impulses having ditierent characteristics, the mechanism being so orgg'anized that impulses of one characteristic will cause the motor fr to be operated while impulses having` a diii'erent charac teristic will` cause the motor il to be operated. These impulses may be of any suitable nature, pneumatic or othe-rivise7 Without departinp,` from the spirit ci the invention.J considered in its broad aspects, but pneumatic impulses are preferred and the particular' mechanism herein illustrated has been designed to use such impulses to the best advantage. rllhis mechanism is tot. lows: w
designates a tracker bar having tone apertures gf `and a stop control aperture g'. The present invention is not concerned with the means V1which are controlled from the tone-apertures g to control the individual elements of the sets of tone elements and hence such means7 which may be oit any suitable naturej not herein disclosed.
duct 50 leads from the stop control aperture f/ and has branches 50'b1 and 50" which respectively extend to priinarj)7 stop control members Il and l and serve to conduct the operating impulses to said members trom the duct 50. These members l'l and l, respectively, operate pneumatics J and li. to make and break circuits herein- :ritter set torth, which control Vthe operation ot secondary control members L and M, las hereinafter explained. .As all of these im- ]'iulses traverse the common duct 50, it is ai i parent that there must be a selective function exercised in order that either ot the motors A, B may be automatically manipulated alone. To this end the controlling nien'ibers lil and l are functionallyT respon'- sive7 respectively, to air impulses having` different characteristics., as lonp; and short tor example. rllhus7 member l-lf operates a quick-acting' circuit closing pneumatic J and member l operates a relatively slow-acting circuit closingl pneumatic l.
The member has a chamber l connect- ,d to the branch duct by a channel 5F; a channel 52, vwhich is under suction 'from a suitable source; a membrane, 52%, separating the chambers 5l and 52 from eachother; a valve chamber 5d: having' a suction port 54A and an atmospheric port 54.3. and also having a duct 5l extending to the interior ci pneumatic Yl. and a valve having tivo valve men'ibers and 55a. in. the chamber and also having; a stein in operative relation with the membrane The member l-l also has a bleed duct 55C having); communication With the chamber 52 and branch duct 50, lt
Will be apparent that when an air impulse is admitted to chamber 51.. member 53 will expand and cause the valve to open suction port 54 and close atmospheric port 54h, thereby placing pneumatic J under suction and causing it to collapse.
The movable board of Athis pneumatic is provided with a contar-1t member 56 which is adapted to bridge vthe space between tivo contact Wires 57 and 58. These Wires lorm part of an electric circuit which, when closed, energizes an electromagnet 59, said circuit being hereinafter traced. The magnet 59 has its armature 60 arranged to control an atmospheric duct 61 extending to a chamber 62 in a secondaryl control member L. This control member has a suction channel 63 which is separable from chamber 62 by a membrane 64, a valve chamber 65 having a suction port 66 and an atmospheric port 67 and a valve having two members, 68 and 69, in the chamber 65, and also having a stem 70 in operative relation with the membrane 64. Accordingly it will be apparent that when the magnet 59 is energized air at atmospheric pressure is admitted to chamber 62, thereby expanding the membrane 64 Which acts upon the valve to open the suction. port 66 and close the atmospheric port 67. Chamber 65 is thus placed under suction. This chamber is in commiinication` through a port 71 and channel v71, with a duct 72 which has communication With the interior oi the motor A. This motor is provided With a spring m for expanding it when the tension of the air Within the motor is the same as that outside the pneumatic.
The primary controlmember I includes a chamber 75 to Which the branch duct 50b extends; a suction channel 76, which is separated from the chamber 75 by a membrane 77 and is connected thereto by a bleed hole 76; a valve chamber 78, having a suction port 79, and an atmospheric port S; and a valve member Si mounted in the chamber 78 and having a stem 82 in operative relation with the membrane 77. The member' I also has a channel 83 Which is connected to the valve chamber, 78, by a port 84 and with the atmosphere by a port 85, and regulating screws Sb and S7 are provided for said ports, respectively, in order that the tension oit the air in the channel SH may be regulated to a nicety. A duct 88 is connected to the channel S3 between the regulating screws and extends thence to the interior of the secondary circuit closing pneumatic K. which has a contact S9 adapted to bridge the space between two (ifontact wires 90 and 9i.. which torni parts ci" an electric circuit. hereinafter traced,` and which circuit cnergizes an electro-magnet 02 whose armature 93 opens and closes a duct 94 through which air at atmospheric pressure is admitted to aI chamber 95 in a secondary control member M. This secondary control member includes, in addition to the chamber 95, a suction channel 96, Which is separated from the chamber 95 by a membrane 97, and is connected therewith by a bleed duct 96a; a valve chamber 98 having a suction port 99 and an atmospheric port 100; and valve members 101 and 102 in the valve chamber, for closing the ports 99 andl 100 respectively, and provided with a stem 103 in operative relation with the membrane 97. A duct 104 has communication with the valve chamber 98, and With the interior of the motor B. This motor hasa spring 0 for expanding it When the tension of the air Within and Without it are equal to each other.
It remains now only to trace the various circuits and set forth the operation in a general Way, as follows Assuming that both stops are closed and hence the corresponding sets of tone elements are out of action:
If novv it be desired to open stop A., a short pneumatic impulse is admit-ted to duct 50 and will be conducted to the primary control member H, through branch 50a. This impulse will be suiiicientto cause pneumatic J to collapse and close the circuit through magnet 59. This circuit is' as follows: From the positive pole of a. suitable source of electrical potential, indicated at X, by Way of `a bus bar X and Wire m to Contact Wire' 57 and thence through contact 56, contact wire S and Wire to the positive terminal v2 of the magnet 59, through said magnet to the terminal m3 at its negative side, and back to the negative pole of the battery by way of Wire m4 and negative bus bar X2. The magnet 59 being lthus energized causes air at atmospheric pressure to be admitted to chamber 62 of secondary control member L and this in turn resul-ts in the collapsing of pneumatic A. which through its described connection with stop A. throws the latter to its open or on position. This movement of the stop A causes the contact member to engage contact l1 and to bridge the space between said Contact 11 and contact 12. This closes the following circuit through magnet 13, namely; from the positive pole of the source X to the terminal 955 at the positive side of said magnet, -thence through said magnet to the terminal we at the negative side thereof, and to contact member 11 by way of Wire a, and through contact member 10 to contact member 12 and back to the source by Way of Wire w8 and bus bar X2. This causes motor D to collapse and open the corresponding stop valve (not Shown) Whereupon, any ot the tone elements of the set controlled by said valve may speak when the corresponding tone valve is opened.
Vhen this operation has taken place 'duct and branch duct 50a will be closed. This will break the circuit to magnet 59 which AflO T he tension ot the, air in motor @Y is thus ehzmgefl to atmospheric, Whereupoii it experi cls aiitl while expaudiug merel)T adjusts the connecting' liulsV into such relatioii to the stop A that the next collapsing movement of the motor will throw the stop to its other or off position. lu other Words, the stop A is thrown aut miatioally only by the oollapsiup; iiiovemeiu; oil motor rif, the expansive iioifemeut ot said motor-merely acting to place the connecting liule iu such relation to the stop A. that successive colle-psiife movements oi the motor will throw the stop first to one au-fl theu to its other positiona Thus it a short pneumatic impulse is' ad mitteel to duet 5G it will Collapse the pueumatic l? thereby closing' `the circuit to magi het 59 and this iu turu will Cause motor i to collapse and throwv the stop to its ou po- Sitiou it said stop he in its otl petition when motor A ie collapsed, This rompletes the circuit to stop iiiztgiiet l/ which hi turn operates the stop valve (not shoivu) aiul ther-:3- hy opens up comiiuimieatiou'oi the corre spending u'iud pass with Vthe several 'oue elements oi the set comic/ete@ to said, pas`- sage.

The pneumatic K is shown as being longer than the pneumatic .l and hence its movable board is required to travel a greater distance in order to close the circuit through magnet 92 than is required ol" the movable board of pneumatic J in the completion of the circuit through magnet 59.
Having' thus described the invention, what I believe to be new and desire to secure by Letters Patent, is
