JAMES CLARKE HAGEY, 0F CHICAGO, ILLINOIS, ASSIGNOR, OF ONE-HALF 'I'O THE CABLE COMPANY, 0F CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
POWER-REGULATING- APARATUS.
Application led Aprilrl, 1913.
To all whom t may concern.'
Be it known that I, JAMESC. I-IAGEY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Power-Regulating Apparatus, 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 power regulating apparatus. y
Prominent objects of the invention are to provide a simple, practical and effective power regulating or controlling apparatus; to arrange for the adjustment of thc power to the requirements or needs of the apparatus or instrument with which the apparatus is associated; to secure such adjustment of power automatically `if desired; to permit the effective power, which is adjusted to the needs or requirements of the associated apparatus or instrument, to be changed or varied at will; and to accomplish the foregoing and other desirable results in a simple and expeditious manner.
In this application, I have shown my invention applied to a pneumatically operated musical instrument player, such, for example, as a player piano or piano player, but it will be understood that the invention is not limited to application to such instrument, nor, in fact, is it limited to musical instruments at all, being applicable to a wide variety of devices, instruments and 'apparatus.
In the accompanying` drawings, Figure 1 is a view, somewhat diagrammatic of a portion of an automatic playing device for musical instruments embodying my present invention;
Fig'. 2 is a longitudinal sectional view of a slightly modified arrangement,lthe tracker being omitted from this figure;
Fig. 3 is a View, similar to Fig. 2, of a further modiiication;
Figs. el, 5, 6, 7 and 8, are views, more or less diagrammatic, of further modifications.
Referring first to Fig. 1, I show a tracker 1, having the usual set of apertures 2-2 and also having an extra set of apertures Specification of Letters Patent.
Patent-cd May 8, 191 '7.
Serial No. 761,470.
3-3 which are preferably the same in number as those of the usual set and located individually directly in the rearl of the same. The apertures 3*?) are in communication with a common duct or passage 4 running lengthwise of the tracker and communicating with a pipe 5, to which is connected a liexible tube 6. The tube 6 extends to certain apparatus suitably located kin the instrument at a proper distance from the tracker. rllhis apparatus comprises a small pneumatic 7 having a swinging leaf 8 and a large pneumatic 9 having a swinging leaf 10 on which the pneumatic 7 is mounted, a board 11 being lpreferably interposed between the pneumatics 7 and 9. The pneumatic 9 is mounted, in turn, upon some convenient part of the instrument, las, for example, by securing the base 12 thereof to a rigid structure 18. y The tube 6 .runs directly to the pneumatic' 7 and communicates with the interior thereof. Said pneumatic 7 contains'a swinging valve 15 having a bleed 15-, which valve has a hinged connection with a block 16 secured to the base 17 of said pneumatic 7. The other end of the valve 15 has a link connection with the swinging leaf 8 of the pneumatic 7, by meansV of a pivoted link 18. The valve 15. controls a port 19 in the base 17 and board 11, said port 19 consequently communicatingwith the interior of the large pneumatic 9, the board 11 covering a cut-away portion 20 in the leaf 10 of` said pneumatic 9. lWithin the large pneumatic 9 is arranged another swinging valve 21 having a bleed 21, which valve 21 controls a large port 22 in the base 12, Ysaid valve 21 forming the movable leaf of apneumatic 21b mounted on an arm 21C secured to the base 12. The swinging end of the valve 21 is connected by a link or rod 23, which extends through an opening 24: in the board 11, to a swinging link 25, the left hand end of which is pivotally connected to a long arm 26 which is, in turn, pivotally connected to a standard 27 mounted upon the swinging leaf of the pneumatic 9. The other end of the link 25 is pivotally connected with a clip or lug 2S on the swinging leaf 8 of the small pneumatic 7. The free end of the swinging arm 26 is connected with a longitudinally adjustable rod 29, which latter' is understood to be a controlling rod for manual or automatic control and to extend to some suitable controlling device for purposes hereinafter to be explained. The port 22 is understood to lead to the apparatus for reducing air pressure and another port 30 is understood to lead to the action, the arrangement thus described therefore being suitably interposed so as to control the pressure of air applicable to the action. A spring' 31 is connected to the swinging leaf of the large pneumatic 9 and extended to a suitable support or tension member 32 carried by a supporting strip 33, a pin 3-1 being provided to vary the tension of the spring 31 and thereby vary the tension applicable to the reduced air pressure. Another spring 35 is connected to the end of the link 25 and extended to a tension block 36 having a pin 37 to adjust the tension of said spring 35, said block 36 being carried by a bracket 38 secured to the base 17 of the pneumatic 7.
In an application filed by me May 11, 1908, Serial No. 432,200, I have shown a pressure regulator embodying an arrangement similar to the spring arrangement of the springs 31 and 35 and a valve arrangement similar to the arrangement of the valve 21 and have set forth and claimed said arrangements in said other application.
Thus it will be seen that, in operation, perforations in a traveling music sheet will first open the extra or rear ports 3, 3 and will then open the usual ports 2, 2 to cause the sounding of notes, the latter being done by means of the ports 2, 2 and playing mechanism in the usual way. When ports 3, 3 are opened, atmospheric air will be admitted into the duct or passage 4 and thence into the tube 6 and into the interior 0f the pneumatic 7. This will cause or tend to cause an expansion of said pneumatic 7, under the influence of spring 35 andamovenient of valve 15 to open or further open port 19. Obviously, varying numbers of note perfor-ations will open varying numbers of ports 3-3 and the quantity of air admitted to pneumatic 7 will therefore vary accordingly. I prefer to have pneumatic 7 and bleed 15a so constructed that the pneumatic will remain collapsed and valve 15 remain closed when three or four notes are to be sounded. To accomplish this, I make bleed 15a large enough to permit the air from three or four open ports 3-3 to be drawn therethrough. When a greater number of notes are to be sounded, the air admitted through the greater number of ports 3 3 cannot be taken care of by bleed 15a, whereupon an expansion of the pneumatic 7, under the influence of spring 35, takes place and valve 15 is opened to a position which permits the greater quantity of air entering through tube to pass through port 19. Thus, during operation of the device, the position of valve 15 and of swinging leaf 8 is always determined by and will indicate the number of open ports 3 3 greater than three or four. The various positions of swinging leaf 8 thus obtained (through variations in the number of open ports 3-3) act, through the swinging of link 25 upon its pivotal connection with arm 26, to adjust link 23 and valve 21 and, since pneumatic 7 and one end of arm 26 are mounted upon swinging leaf 10, such adjustment of valve 21 will be relative to the swinging leaf 10. A11 expansion of pneumatic 7 and a consequent adjustment of valve 21 nearer to swinging leaf 10 opens or further opens port 22 and permits a further reduction of pressure in pneumatic 9 which effects a further collapse of that pneumatic, moving swinging leaf 10 and thereby placing greater strain upon spring 31 until valve 21 has been restored to its proper p0- sition, throttling port 22. The construction and adjustment of springs 31 and 35 are such that the various positions of swinging leaf 10 thus automatically provided under the control of the note perforations will insure the proper air pressure in pneumatic 9 for the varying numbers of notes represented by those perforations.
Thus there is an automatic adjustment of the pressure to the needs or requirements of the apparatus, which in this case is understood to be the action of the player piano or piano player. It will be noted that, in the operation of the device, when the music sheet is on the tracker with no perforations in register with the apertures 2, 2 and 3, 3, and when at such time the pumping or other wind inducing mechanism is operated, the air will be exhausted to a greater or less degree from the striking pneumatics by way of the ports 30 and 22 and pneumatic 9, and then the valve 21 will be drawn shut and held in that position. When now a few perforations in the music sheet, say for example, three, come into register with the ports 3, 3 and a. small amount of air is admitted to the duct 4, and pneumatic 7 by way of tube 6, as previously stated, this amount of air is insuiicient to expand the pneumatic 7 because the air can escape through the bleed 15EL in the valve 15, or looked at in another way, the bleed 15a is sufficiently large to vent the slight excess pressure in the pneumatic 7 without allowing said slight excess pressure to have any effect in expanding said pneumatic 7. The air from pneumatic 7, or the slight excess pressure, however the matter may be considered, being communicated into the interior of the pneumatic 9 by way of bleed 15, causes a very slight opening movement of pneumatic 9 because, as will be seen, the valve 21 has no accessible bleed, said valve being part of the pneumatic 21h. rlhis slight opening movement ot' the pneumatic 9 causes a slight opening of the valve 21 because of the mounting of the pneumatic 7 and associated valve adjusting devices upon the swinging leaf of said pneumatic 9. At this time there is within said pneumatic 9 a degree of pressure suflicient to sound the three notes with the desired degree of strength. When now the three perforations of the music sheet come into register with the ports 2 2, said notes will be sounded and the air in the striking pneumaties of said notes will be exhausted into the action chest or otherl suitable chamber, and will then be exhausted through the regulating apparatus disclosed herein, said air, or the increase of pressure, therefrom being communicated to the port 30 and thence into the interior of the pneumatic 9. Wvhen this takes place, the pneumatic 9, under the influence of spring 31, is instantaneously opened a moderate amount, thereby permitting the air to escape from within the pneumatic 9, or looked at the other way, allowing the pressure therein to be again reduced by the opening of the valve 21, upon which the pneumatic 9 will be instantly and automatically restored to its former position with the valve 21 closed. If three notes are again sounded, the same series of movements will take place. If, however, a materially greater number of notes are to be sounded, say for example, ten, the air admitted into the ten ports 3, 3 will cause a substantial opening movement on the part of the pneumatic 7, thereby causing substantial opening movements on the parts of the valves 15 and 21. This partially unthrottles the port 22 and permits the establishment of a greater degree of exhaustion within the pneumatic 9, such degree of exhaustion as is suflicient to sound the ten notes with the same force as the previously mentioned three notes were sounded, Pneumatic 7 and valve 15 will remain in the positions just described as long` as the number of open ports 3 3 remains unchanged but valve 21 will be instantly returned, through the further reduction of pressure in pneumatic 9 and the consequent closing movement of leaf 10, as hereinbefore described, to properly throttle port 22, so that said pneumatic 9, immediately prior to the sounding` of the notes, is in approximately a closed condition with the proper strain upon spring 31 and with the proper degree of pressure therein to sound the number oit' notes about to be sounded with the desired strength. Upon the opening of the ten ports 2 2 to sound these ten notes, the ten note-sounding pneumatics are sutH- ciently exhausted by the degree of pressure established in the action chest through port 30 and, immediately upon or after the operation of said note-sounding pneumatics, the air from within the same enters pneumatic 9 through port 30. lhieumatic 9, under the influence of spring 31, and valve 21 are instantly opened so that the air entering pneumatic 9 from the ten note-sounding pneumatics is immediately withdrawn through port 22, pressure is instantly reduced again in said pneumatic and 'valve 21 is instantly returned to its approximately closed position, unless a new adjustment thereof is already required. Thus it will be seen the apparatus controls the pressure to supply the needs of the instrument, in this case a piano player or player piano action, with accuracy and precision, and brings about this control in such a way that the needs or requirements of the instrument are, as it were, anticipated or predetermined and the pressure adjusted in advance. lt will also be seen that, after any operation to adjust pressure, the apparatus will be quickly restored to condition for further operation.
Of course, the adjustments of valve 21 and the resulting movements of swinging leaf 10 are substantially simultaneous and, as a consequence, port 22 is rarely, it' ever, opened very much by even pronounced expansive movements of pneumatic 7. Likewise, pneumatic 7 is responsive to such a degree that the proper adjustments of leaf 10 are obtained even when note perforations pass with great rapidity across ports 3 3 and 2- 2. Should it be possible, however, to pass such perforations across the two sets of ports so rapidly as to not allow time for adjustment of leaf 10, the response of pneumatic 7' in positioning valve 21 in accordance with the number ot' opened ports 3 3 will be at least as immediate as the response of the note-sounding pneumatics controlled through note-apertures 2 2 and port will thus be properly adjusted in time for the passing' of the different volume of air through port 30 and pneumatic 9. Under most conditions, therefore, the adjustment of valve 21 will be suliiciently prior to the operation of the note-sounding pneumatics to cause an adjustment of pressure and a storing of such adjusted pressure in pneumatie 9 but there may be occasions when, as I have described, the operation of the note-sounding pneumatics is so nearly simultaneous with the adjustment of valve 21 that such an adjustment of the valve causes an adjustment of flow without necessarily varying the pressure.
The red 29 is extended up to some convenient point for manual operation or connected with some device for manual or other desired control, so as to permit an adjustment of the arm 26 so as to control the air pressure on the action by adjusting the link 25 and valve 21. This allows any del so sired air pressure to be established by the rod 29, and then there will be automatic adjustment with reference to this predetermined pressure for varying numbers 0f the notes or other requirements.
Fig. 2 illustrates an arrangement more especially adapted for use in connection with a motor, the arrangement of Fig. 1 being well adapted for use in connection with an action. The arrangement of Fig. 2 is quite similar to that of Fig. 1, the tube 6 being understood to be extended to the tracker and connected with special ports 3, 3 therein, just as in the case of Fig. 1. The rest of the mechanism is also the same as that of Fig. 1, in many respects, but there are some differences. The rod 29 and its cooperating link 25 and arm 26 are, for example, not present in Fig. 2, and, furthermore, the swinging leaf 8 of the pneumatic 7 is provided with a strip 8EL which projects beyond the end of the swinging leaf 8, and to the end of this strip 8 is connected the rod 23 which extends to the valve 21. Thus it will be seen that the arrangement of Fig. 2 operates in a reverse manner to that of Fig. 1, the pneumatic 7 closing the valve 21 when a larger number of the ports 3, 3 is opened and opening said valve 21 as the number of ports 3, 3 is decreased. This brings about proper regulation for the motor, inasmuch as the motorneeds less pressure to drive it when there is a larger number of ports 3, 3 and 2, 2 open, there being at such time less suction on the music sheet than when only a few of the ports 3, 3 and 2, 2 are open.
Referring to the arrangement shown in Fig. 3, it will be seen that this arrangement is substantially that shown in Fig. 1, except that the manual or other controlling rod 29 with coperating arm 26 is not present. The arrangement of Fig. 3 therefore will operate as the arrangement of Fig. 1, but will not permit the alteration of the predetermined air pressure as in Fig. 1.
Referring to Fig. 4, I show a pneumatic 40 corresponding to the pneumatic 9 of the preceding figures, and a second pneumatic 41 corresponding to the small pneumatic 7 of the preceding figures. The two pneumatics 40 and 41 are not mounted together as in the preceding arrangements, but are separated from each other. The pneumatic 40 contai'ns a slide valve 42 which is connected by a link 43 with the movable leaf of the pneumatic 40, said link 43 being pivoted at one end to the valve and at the other end to the movable leaf of the pneumatic. The device is also provided with a slidable valve seat 42a having a port 42h, and said slidable valve seat 42 is connected by a rod 44 with a bell crank 45 which is in turn connected with a rod or link 46 extending to and connected with a projection or extension 47 of the movable leaf 48 of the pneumatic 41. A spring 49 is connected to the movable leaf of the pneumatic 40, said spring 49 tending to hold said' pneumatic open. A spring 50 is connected with the leaf 48 of the pneumatic 41, the spring 50 tending to hold said pneumatic 41 open. Within the pneumatic 41 is the valve 15, the same as in the other arrangements. A tube 52 is in communication with the interior of the pneumatic 41, said tube 52 corresponding to the tube 6 of the preceding arrangements. Another tube 51 connects the interior of the pneumatic 41 with the pressure reducing apparatus.
This arrangement operates in a manner substantially similar to that previously described in connection with the other arrangements. It will benoted, however, that for a small number of notes, where the air coming from the supplemental tracker ports 3, 3 is insulicient to actuate the small pneumatic 41, the large pneumatic 40 is not actuated as is the large pneumatic 9 of the preceding arrangements. On the contrary, the small amount of air from three tracker ports 3, 3, or the small excess pressure from the same, will be exhausted or vented directly from the tube 52 to the tube 51 by way of the bleed 15a. In other respects, the operation of the apparatus will be the same, a relatively large number of note perforations coming into register with the ports 3, 3 causing an expansion of the pneumatic 41, which in turn causes a movement of the valve seat 42a so as to move the port 42b therein from under the valve 42 thus opening communication of port 22 with pneumatic 40 to properly adjust the degree of pressure within the pneumatic 40, whereupon the pneumatic 40 itself collapses sufliciently to cause the valve 42 to follow up and close the port 42b in said valve seat 42"i and thereby close said port 22.
Referring next to Fig. 5, this arrangement is very similar to that of Fig. 4, in so far as the general arrangements of pneumatics 40 and 41a are concerned, the swinging leaf of pneumatic 40, however, being connected with the swinging leaf of pneumatic 41 by spring 55, The pneumatic 40 contains a pivoted lever' 5G operating a valve 57 .which controls the port 22 in the board 59, the lever 56 being operated directly by the swinging leaf 60 of pneumatic 40, A spring 61 is connected with the swinging leaf of pneumatic 41, tending to hold said pneumatic open. In this arrangement the pressure adjustment is obtained by the increased tension placed upon spring 55 by an expansion of pneumatic 41a through the opening of the relatively large number of supplemental tracker ports. In such case it will be understood that the tracker ports 2, 2 and 3, 3 are sufficiently close together to permit the perforations of the music sheet to maintain the ports 3, 3 open until the ports 2, 2 are also open, so that there shall be no closure of ports 3, 3 until the corresponding ports 2, :2 are opened, in which way the pneumatic 41a will be maintained in its expanded condition until the notes are sounded.
In vthis ligure I also show a pneumatic action 97 connected with the windway 98 which communicates with the port 30. The form of action shown has a valve 99 on a spindle 100 running to a pneumatic 101, controlled by a tube 102, which is understood to run to the tracker. The pneumatic action 97 is shown controlling a piano action having a sticker 103, a hammer 104, and a string 105, the wippen 106 being actuated by a pneumatic 107.
In Fig. 6 I have shown the pneumatic 7 controllingthe port 62 of a side passage 63 of the windway 64: and have also shown a valve 65 in said wind way connected by a link 66 with the swinging leaf 8 of the pneumatic 7, so that said pneumatic 7 also controls said valve 65. A spring 67 tends to hold said pneumatic 7 normally open. By this arrangement an expansion on the part of the pneumatic 7 causes an adjustment of the valve 65 and thereby a control of the windway 64, this control being by a windway valve as seen, instead of by a valve Within a pneumatic forming part of the apparatus as in the preceding arrangements.
In Fig. 7 I have shown an arrangement somewhat similar to that of Fig. 6, Fig. 7 having the pneumatic 7 controlling a side passage 63 andvalso controlling a valve 65 in a windway from which the passage 63 eX- tends. In F ig. 7, however, the windway 64a, from which the passage 68 extends, is a branch windway of the main windway 69. This windway 69 is subject to control by another regulator or controller which is a form of controller heretofore employed, the same having a pneumatic 70 communicating by port 71 with the windway 69 and having a valve 72 controlled by the pneumatic 70. rFhus there is automatic regulation of the wind in the branch windway 64: in accordance with my invention, and also regulation by means of the controller-pneumatic 7 0.
7ieferring to Fig. 8, I show in this ligure an arrangement embodying my invention and adapted for use in connection with electrically operated player pianos or like devices. In this arrangement I show two metallic bars 75 and 76 serving as tracker bars or members, and a music sheet. 77 having perforations 78 being drawn over the same. I also show two other bars 79 and 80, whereof the bar 79 is provided with a series of metallic contact lingers 81 which are all connected with it, so that said fingers S1 are in effect connected with one another. The bar 80 is of insulating material and is provided with lingers 82. The lingers 81 and 82 are adapted to enter perforations 7 8 in the traveling music sheet 7 7 so that the lingers 81 and S2 may make contact with their respective bars 75 and 76. A conductor 83 is connected with a solenoid 84, whose core 85 has its lower end submerged in a mercury cup S6. The upper end of the core 85 is suspended from a spring 87, and a conductor 88 is connected with said core 85 and extended thence to a battery 89. An actuating magnet 90 is shown under the piano key 91, the latter having an armature 92 which is attracted w ien the magnet 90 is energized so as to cause the actuation of the key 91 and consequent playing of the instrument. rlhe magnet 90 is connected by a conductor 9S with one of the lingers 82, it being understood that other keys of the instrument are provided with similar magnets 90 which are connected with other lingers 82. A conductor 9a extends from the battery 89 and is branched at 95 and 96, which branches are connected with the bars 75 and 76, respectively.
In the operation of this mechanism, it will be seen that, as the music sheet 77 advances and the lingers 81 enter the perforations 78 in said music sheet, said lingers close a circuit through conductor 83, solenoid S4, conductors 83 and S8, and battery 89, from which connection is made to bar 75 by conductors 94 and 95. The current passing through the solenoid Slt energizes the same and thereby causes the core 85 to descend farther into the mercury cup 86. This of course reduces the resistance of the core 85. Obviously, the greater the number of perforations passing over the bar 75, the greater the number of lingers 81-81 caused to make contact with the bar 7 5, whereby a larver amount of current is passed through the solenoid Set according to the number of perforations passing over the bar 75, and thereby the greater distance will the core 85 be forced down into the mercury cup S6. When, therefore, the music sheet perforations pass over the bar 76, the lingers 82H82 enter the same, causing corresponding magnets 90 to actuate the corresponding keys 91. The amount of current to be distributed to this larger number of magnets will be greater, whereby each magnet may have the same amount of current and operate with the same power, notl.
withstanding the number of magnets operated. rIhus it will be seen that the power of the playing, or operation of the instrument, is controlled in this arrangement in substantially the same manner as in preceding arrangements.
It will be understood that, while I have herein shown the invention applied to a certain kind of musical instrument, the invention is not to be limited to such instrument nor music sheet instruments at all, but is applicable to a wide variety of instruments, devices and apparatus of various kinds and natures.
It will be understood that changes and modifications can be made without departing from the spirit of the invention.
