Application :filed September 16, 1911. Serial No. 649,772.
To aZZ whom t may concern:
Be it known that l, FREDRICK W. SMITH, a subject of Great Britain, residing at North Tonawanda, in the county of Niagara and State of N ew York, have invented a new and useful Electropneumatic Organ, of which the fol-lowingV is 'a specification.
This invention relates to electro-pneumatically operated musical instruments.
The invention has for one of its objects the provision of a tracker-board of novel construction which is provided, in addition to the usual openings, with a master opening and other openings arranged, combined and related to the master opening and to the ordinary note openings in a new manner, these ladditional holes or openings being adapted for use in connection with certain other improved and novel instrumentalities and with the perforated music sheet for the control of one or more organs, pianos, or other musical instruments.
Another object of the invention is the provision of a tracker-board having, in addition to the usual note holes or openings, a master hole or opening and other holes and an electro-pneumatically operated system of novel arrangement and novel features combined therewith in a new manner and with a multi-manual pipe or reed organ or piano, whereby the diHerent manuals are automatically controlled by the music sheet so that they are rendered adaptable for playing by the musicy sheet, and to enable any two or more manuals to be automatically played simultaneously and any change in playing from one manual to another may -be arl ranged; further', whereby all changes of. registration on the draw stops, couplers, swell shades, combinations or other movements involved in organ playing-may be'efectuated.
Another object of the invention is the provision of diiierent Vnovel apparatus for the control of electrical switches and the control of electric circuits in an electro-pneumatically operated and controlled system for musical instruments.
The invention embodies, first, a trackerboard having a new arrangement of perforaf tions or holes and a master hole, in addition to the ordinary note holes; second, the combination of such novel tracker-board with a novel electro pneumatically operated and controlled system for playing musical instruments; third, a novel electro-pneumatic circuit controller, fourth, a novel electro-pneumatic switch operator; fifth, a novel pneumatlcally operated contact; and, further, certain improved constructions and combinations; and systems, all of which will be more fully set forth hereinafter.
in the accompanying drawings:

T designates a section of a tracker-board which is provided with the usual note holes l which control the pneumatics that sound the musical instrument, whether the latter be an organ or piano and whether electropneumatically, pneumatically, or mechanically operated. vThe holes or openings 1 are one hundred and ten in number and all of these holes except those included in the transverse rows T which appear at l are used as' playing holes. lfn addition to the note holes l provide series of other holes T which controll the action of the musical instrument in such manner as to throw on or 01T the different organs or manuals to be played electro-pneumatically by means of the perforations in 'the music sheet which passes over the tracker-board at will. The tracker-board has in all two hundred and forty-three holes, more or less, as may be required, the number of the holes depending on the size of the instrument and the number of the various organs or other musical devices to be operated. Of this total of two hundred and fortythree holes, more or less,
of one of the pneuof an electrically an organ pipe; of a part of the switchthe note holes l constitute one hundred and ten to provide for the different manuals and which are divided between solo and accompaniment. Each series of holes T consists of two rows, one row being adapted to throw the organ or musical instrument actions on and the other row to throw them off in a manner which will appear hereinafter. The openingsl, while in line with note openings 1, are not note openings but are a part of the control openings T.
I provide a 'separate hole or perforation Z in the tracker-board which is in the nature of a master hole for the reason that in controlling the various electrical switches, it controls the master switch R. I also provide the single row of controlling holes T2 which includes the hole T3 forming no partof the series of playing or note holes 1.
Leading from the holes 1, as indicated by the broken lines K', are small air tubes or pipes which extend 'to the pneumato-electric contacts K, one of -which is shown in Fig. 4, these contacts corresponding in number to the playing or note holes in the tracker-board with which their pipes K are connected. The contacts K control the electric circuits, inthe first instance, said circuits receiving their energization from the electric battery U, and all of the electrical energizations of operative parts hereinafter described are controlled by the pneumato-electric master switch R which is of the construction vshown in Fig. 4, so that except when vthe master hole or perforation Z is uncovered by the music sheet, regardless of lwhat other holes are uncovered, electrical energization of the parts cannot occur. ten of the switches K, one for each of the note holes l.
Pneumato-electric switches K4 corresponding in construction to the switches K and in number to the controlling holes T, including the holes 1, are connected by pipes K3 to said holes. Pneumato-electric switches K5 corresponding innumber to the controlling holes T2, T3, are connected to said holes by pipes K2.
I also provide electro-pneumatic switch operators L whose purpose is to throw on or off the electric switches of the electric switch-board N to thereby pull the stops of the organs 100, 101, 102, 103, these being, respectively, the great organ, the choir organ, the swell organ and the solo organ. There are as many (four in the present instance) of the switch operators L as there are organs. One of these electric switch throwers is shown in detail in Fig. 2 and all may be of the same construction. A modified construction of the electro-pneumatic apparatus L is shown at M in Fig. 6 and is used to operate the valve in the chestadmitting air pressure to the organ pipe when it is played.
There are one hundred and- The electric switch-boardN, Figs. 7 to 11, has a plurality of fixed metallic plates N (sixty-one in the present instance) a portion' of which appear. These plates have circuits S1, S11, S12, S11, in the form of cables, each having a plurality of electrical conductors (sixty-one in the present in stance), the independent conductors S of which run to the sixty-one organ pipes provided in each of the respective organs 100, 101, 102, 103, whereby the pipes P, of which there are sixty-one in each organ, are elec tro-pneumatically operated. The cables S10, S11, S12, S13, have their respective conductors (sixty-one'for each organ) connected to independent sets of switch bars or plates N. The switch-board plates N are set vertically and insulated from each other, each of the sixty-one wires of any cable running from its plates to its corresponding apparatus M of which there are sixty-one for each organ; thus there is a wire or circuit from an apparatus M for the C pipe to the first of the metallic plates on the switch-board; another from the Cif pipe to the second of the plates' and so on. The switchboard has rockable switch bars 30 corresponding in number to the organs, there'being four such bars 30 in the present instance to control the organs 100, 101, 102, 103. Each switch bar 30 carries contacts 31 corresponding in number to the plates N, there being sixty-one contacts 31 on each bar in the present instance, to control the circuits of the sixty-,one apparatuses M of the given organ and thus to independently control the sixty-one pipes of that organ.
The pneumato-electric contacts K1, K5, R, are of the construction shown in Fig. 4, the contacts, except the master contact R which is single, being preferably arranged in multiple and contained in a single case or box which is provided in its lower part with a plurality of chambers 4, each connected by its o'wn pipe, such as KA1 to its hole in the tracker-board. Above each chamber 4 is a suction chamber 2. All of the suction chambers 2 are connected 'to any suitable suction reservoir which may be employed to provide suction for the apparatus. The chambers 2 and 4 are connected by .bleed holes 6 and each set of chambers is sepa rated by its own diaphragm 7 Above the chamber 2 is a contact chamber 2, an opening connecting said chambers, but the two chambers are sealed against communication by a flexible diaphragm 8. There is'a stem 9 disposed between the diaphragms and having a part extending through diaphragm 8 and provided with a button 10', by which an electrical spring contact 11 may be made to engage another electrical contact 12 located in chamber 2; the contacts 11 and 12 are normally separated and the diaphragm 7 is depressed. When an opening in the music sheet registers with an opening in the tracker-board, atmospheric pressure passes l into the corresponding chamber 4', and overbalances the suction on opposite sides of the diaphragm 7' so that the diaphragm 7 lifts, the stem 9' is forced up and the button 10' forces the contact 1l' into engagement with the contact 12', thus completing the given electrical circuit of the circuits Q.
The organ-pipe-controlling circuits S10.
S11, S12, S13, are each controlled at the port 17', the chamber 15' and the port 14'.
A port 16. constitutes an outlet for the chamber 15'. Located within, but out of communication with the chamber 13', is a valveoperating bellows 18' which is connected to a valve stem, 21' carrying a valve 22' which is adapted to seat over and to close either the porty14' or the port 16' and to'either cut ol'I chamber 13' from chamber 15' or to place said chambers in communication. lVhen said chambers are cut olf, the pressure in bellows 19' can exhaust through port 16'. Mounted on the apparatus is a chamber 22" which is in communication by a port 27 with the interior of the bellows 18' and is also in communication with the atmosphere through a port 25'. Apertures 26' alford communication between the chamber 13' and the port 27 by way of the interior of the casing 22". These ports are closed or opened according to the position of a disk valve 24' which constitutes an armature for an. electro-magnet 23'. Under normal conditions, the pressure in the chamber 13' passing through the ports 26', forces the armature valve 24' against the port 25' and covers it'so as to exclude-atmospheric pressure. The pressure in chamber 13' has access to bellows 1.8' so that the expanslon thereof keeps the valve 21' against the port 16', excluding atmospheric pressure through said port. Consequently, thev pressure in chamber 13' has access to bellows 19' and expands the latter forcing up the stem 20". If, however, the magnet 23' is energized through its circuit 70, 71, supplied by battery U, the armature 24' is attracted to the poles of the magnet, thereby covering and closing the port 26', shutting oil?7 communication between chamber 13' and bellows 18' and admitting atmospheric pressure into port 27'. The pressure in chamber 13' being greater than the atmospheric pressure,
v immediately forces up the lower member of bellows 18' and causes the valve 22' to close the opening 14'. Pressure to bellows 19' being cut 0E, the pressure therein escapes through the port 16' and the pressure in chamber 13' collapses said bellows so that the stem 20' is moved and the lever 29' which is attached to the switch bar 30' corresponding to the organ controlled by the apparatus L selected, causes all of the sixtyone contacts 31' of said bar 30' to engage with all the metallic plates N' as indicated at 32' which control the given organ. The four apparatuses L`,'respectively control the playing of the organs 100, 101, 102, 103, and are in turn operated only when the perforation in the music sheet registers with a selected opening in any of the series T'. Unless the set of contacts 31' engages the set of plates N' which control the circuits S10, S11, S12, S13, for the given organ, that organ cannot be played. v
In order, however, that when this Contact on the switch-board is established it may continue, an apparatussuch as shown in Fig. 5 is provided. The circuit 70 is provided with a switch 33' which is controlled by a handle or lever 51' pivoted at 49' and provided with a cam part adapted to operate the contacts 33', there being provided a bar or projection 48' attached to the lever 51' and operated by a rod 47', which in turn', is shifted in one direction'or the other by bellows 46' and 50'. The bellows 46' is used to close the circuit at 33' and the bellows 50' to open said circuit. The entire apparatus is designated O'. This apparatus is controlled by the controlling apparatus O. If no music sheet is used and the instrument played manually,y the organist may operate the handles 51' at will to control the organs 100, .101, 102, 103.
The controlling apparatus O, Figs. l, 3 and 5, has a suction chamber 34' 'which receives suction from the suction reservoir. In this apparatus is a chamber 44' which has a pipe 45' leading to bellows 46', and the apparatus O being duplex, there is another chamber 44" in communication with bellows 50' by a pipe 45". According as suction is admitted to chamber 44'. or 44" from suction chamber 34', one or the other of the bellows 46' or 50' will collapse. At 38' is shown a bellows carrying a stem 39' to which isat- 120 tached a valve 40' which is adapted to seat against either the ports 41' orA 42', the latter leading to the atmosphere. In the lower part of the apparatus is an electro-magnet 43' which is in the circuit 71. This electro- 125 in chamber 34 draws up the bellows and causes the valve to close the atmospheric port 42 and the suction passing through port 41 and chamber 44 andthrough pipe 45 into bellows 46, causesthe latter bellows to collapse Vand carry up with it its lower arm and stem 47 thereby closing the circuit at' 33. The lever 51 is provided so that theswitch can be closed by hand, if devsired, as for instance when the organ is played by hand without using a music sheet for the tracker bar, and it is desired to control'the organ stops manually. The colla se ofthe bellows 46 maintains the circuit 0. The mechanism() is duplex and is adapted tol operate the bellows 50 just as the bellows 46 is operated, when it is desired to break the circuit at 33. When the breaking of the circuit at 33 is desired, the collapse of the bellows 50 accomplishes that action.
Referring nowto Fig. 6, which shows the mechanism for operatingl the organ pipes in connection with Fig. 1, the pipes P o thel respective organs 100, 101, 102, 103, are arranged in rows, the rows being under the control of .a sliding valve P10 which has holes registering with the' openings leading to th?A various organ pipes P on that line .so'that by shifting the valve P10, ,the holes may be opened or closed. The valves P10 are oper-v` ated at both ends by electro-pneumatic mechanisms like the mechanism L, Fig. 2, and they have stems or arms 20y connected to. the valves Plo and adapted to pull them out or to reverse them so as to play the given combination of pipes P or not. The circuits for the organ stop operated actions which are designated L57 and L5S, are shown at Q, y
being controlled by certain of the pneumatic switches K4; o i
The mechanism M, Figs. 1 and 6, operates in a manner somewhat similar to the operation of the apparatus L.
The apparatus M has a pressure chest 1.3a
connected to the pressure reservoir, a valve 56a controlling admission of pressure to the pipe P, a valve operating bellows 19a subject to pressure from chamber 13a through ports 14a and 15a or to the voiding of its pressurel through port 16a. The ports 14a and 16a are controlled by a valve 22a on a stem 21* connected to bellows 18a which receives pressure through a port 27 a and through ports 26a leading to chamber 13a. An electro-magnet 23a controls an armature valve 24a which either closes the atmospheric port 25 or is attracted b v the magnet 23a and made to close the ports 26a. The operation is substantially the .same as with the apparatus L.
The rows of holes T2, holes, while the holes 2, 2a; 3, 3a; 4, 4a; 5, 5a; 6, 6a of series T control the switchesiand there is a coperation as will'presently appear,
T3' are controlling The holes along thesame horizontal line v2, 2a; 3, 3a, etc., including the hole T4, lead to the various pneumatic switches K4 through the tubes K3 as follows: 2 connects to its pneumatic switch K4 which when put in action, closes the circuit through the electromagnet 43 which thereupon attracts the armature 35 and bellows 38 thereupon rises,
causing the valve 40 to close the port 42. The suction in 34 draws the air through passage 44 and pipe 45,from belloyvs 46'-,
thereby closing the contacts 33 and the cir-- this instance solo organ 103. The operation v i for each organ is the same.
A perforation i lthe music sheet passes along the tracker-board T and comes into register with the left-hand opening of the playing holes 1 which, let us say, is 'to play the C note.y The atmosphere passing through the pipe leading from that particular playing hole to its corresponding pneumato-'electric switch K, will cause electrical contact -to be made at 52 and the electric current will pass into the proper conductor of cable 53 leading to one of the contacts 31, thence through to the corresponding electro-pneumatic apparatus M inthe solo organ chest,I whereupon the apparatus M,
causes the pipe P to speak `itt the valve P10 has been properly set. The stop-setting or controllin apparatus L57, L58, is controlled in a simar manner by other holes among the controlling heles, as for instance by the holes, 7, 7. p
A' However, as long as'thejhnaster hole remains closed, no operations will take p ace,
regardless of how many perforations pass over the diferent'holesin the tracker T, lfor the reason that while the electric circuitwill be otherwise completed from the battery through the various circuit connections conf trolled by the note holes (if any are uncovered), the circuits are not completed past the switch-board N unless the switch -is thrown in at the switch-board. The switches are thrown in by the uncovering of the controlling holes T. For instance, assuming that a hole in the music sheet coincides with the master hole Z, at the same time a hole in the music sheet registers withv the hole`2 of right-hand series of holes T the magneti43 will be energized and close the lswitch 33', setting the apparatus L in motion and closing thevswitch bar of the solo switch 30. Conditions are then such that anyT note in the fas " solo organ may be played as soon as a hole 1 in the tracker-board T registers with a hole in the music sheet. Y
T have set forth the action of only one set of the controlling holes of the tracker-board. The action of all other holes is similar. The holes 2 and 2a, 3 and 3a, 4 and 4a, 5 and 5a of the controlling holes T, control the throwlng E and on of the switches at the electric switch-board. Only four switches are shown, but if it is desired to have more organ actions, a greater number of switches are used and additional holes are provided in the tracker to control them, and in that connection, it is to be understood that it is immaterial which of the holes in the perpendicular lines outside of the master hole Z and controlling holes T2, etc., are used for this purpose, excepting that the hole used to throw the switch on and that used to throw ithe same switch o'inust not be in the same me.
Tn addition to the holes 2, 2a; 3, 8a, etc., 'there are other holes in the series T which are numbered from'l to 100, more or less, which may be used for controlling devices'of any character such as pulling additional stops oif and on, manipulating additional switches, etc., it desired.
With this system of control, the number of holes necessary for the dierent operations is greatly reduced; 'for instance, if it is desired to operate the control represented at 2 and also a stop which is controlled by the opening 9 of the tracker, the holes in the music sheet will be so timed that one opening will register with 2,-another opening with 9, another opening with T4, another opening with T 5 and another opening with the master hole Z. It will be seen that although the hole which is to register with T5 passes directly over the hole T4, no result occurs until it reaches its proper destination for the reason that there is no electrication of any of those horizontal lines controlled by those holes until an opening registers with the master hole Z, whereupon the entire line of controlling holes T4, T, etc., is electrified perpendicularly and then each of the lines horizontally which have been` registered with holes in the music sheet such as T4, 2, 2a, 3, 3a,VV
4, 4, and T5, 7, 7a, 8, 8a, 9, 9a, etc., are also electried and are/ready to act.
wish it understood that the controlling holes T, T2 do not in and of themselves operate the mechanisms in the wind chest which produce the music, but they merely control the switches on the electric switchboard so as to put the system in condition to receive the electrical current when the proper opening in the music sheet registers with one of the playing holes 1 and the electricity is then conveyed to the proper motor M, `or perhaps to four motors in as many separate f wind chests, if all tour switches are on so that all four in that case will speak, although only one hole of the speaking holes has been uncovered. Consequently, one opening of the series 1 is made to play a note in all of the separate organs 100, 101, 102, 103, or one or more of those organs may be selected as desired.
The openings l are all pipe sounding openings except those indicated 1 which are included in the series T, and T3 in series T2. The holes T are only used for controlling stops or swell shutters. Any of the holes of series T can be used such as a few of a few series, or an entire set in all of said series but no holes of series T produce any effect, when uncovered by the music sheet, unless an opening in the music sheet also registers at the same time with master hole Z and another music sheet perforation simultaneously-"registers with one of the holes T, T5, etc. in the same horizontal line with the hole or holes of any of the series T which are opened.
The switch K and its circuit are controlled and energized as with the other switch K andthe circuit 53.
Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is
