Speccatioii of Letters Patent.

Players of'which' .the following is a specitication, reference being had to the accompanying drawings, forming a part thereof.- *The purpose ot' this invention is to pro.-A vide means oroperating the keys of a pipe organ or similar musical instrument at a distance ron'i the keyboard,^be1ng particularly intended for usefin the tuning andrelt'v consists of the features described, and shown in the drawings, as indicated inthe claims. v

InYA the drawings- Figure 1 is a sectional elevation of' the organ-key actuating device. Fig. Q. is a sectional elevation of the switchf board. Fig.- 3 is a partial sectional plan View of the key-actuating devices. is theielectrical wiring diagram 'for the device. Fi 5 is a partial front elevation of the switc i-board. Fig. 6 is a detail of the locking device in operativeposition, the release position being indicated in dotted lines.

Fig. 7 is awiring diagram .indicating the inode oi? connecting the series of control magnets, 5, in a? common circuit with the stiolns-giving magnet, 10.

ln a pipe organ, as is well understood, the. parte requiring attention for tuning'are po sitioned Where the tuner cannot manipulate them and `at the same time reach the manual keys, andas constructed, many of the pipes are often far ,removed fromv the. key-board, being placed wherever space is afforded for them in the building. Consequently, the tuning oi such `organs at present involves the employment of a helper for. theskilled oigantuner,who shall, remain at the key board and operate the keys for sounding various noties as required by the tuner. The

present device .is designed to dispense'with 'the services of suoli ahelper, since it pro vides means electrically connecting the organ key-hoard with an operating key-board at any dist-ance to which an electric current can be eihciently conducted.

lriefiy, the device consists of two mechameiner-vizi: an electro-magnetically-operated actuating mechanism designed to be mounted over the organ keyboard for actu` i, ation ot the organ keys, and a stiucture of" with the upper-edge,

cuit through the solenoid the nature cfa switch-board to resemble the organv key-board,-.that is, having' its switch keys made in theiform of yorgan vkeys and arranged in similar order. 'A single flexible cable, made up of multiplicity of wires and of any desired'length, constit-utes the electrical connectioli'1"y between these two mechanisms. y'

The key-operatingmechanism'will be irs't described. A series of bell-oiankfstrikers,

1, having horizontal and vertical'am`s,and

fulcrumed in bifurcated bri'icket's,-2,l secured to the main housing,y 3, 'of' the'-niechanism, arepositioned with their horizontalflarms, l, extending respectively over the keys A of the manual of an organ, in substantially the kposition assumed by-the fngersoiivt-he performer. To the vertical arm'llof; each bellcrank is coupled a thrust rod," 4.ffhaving a soft-iron armature, 4, secured to, its under side. Directly under this I afnia'tuie is mounted an electro-magnet 5,.esign"d to draw-tlie rod downwardtwhen tthe tiii'cuit is closed, such movement beingresisted by a spring 4 `on the rod. .5 An actuator for the strikers inthe form of a bar, ,6,Heiztending throughout 'the lengtliof tliei'oigaiii" keyboard,and mounted in an approximately vertical position, is liiiilcrumedat,l 6 near its lower`edge,' andn connetedb "fia link 7 and bell crank 8 to the armatures9, 9, of stroke-giving electro-magnets, '10,1'0, inounted exteriorly on the inainlliousi'iig'f. These stroke giving electro #magnets "10", 10, are preferably, but not necessarily,ofthe solenid type, so'that their' armatur'esfi), 9, are plungers. Downward movement off the rod 4, under the influence of itsrmagneb, brings its freer end, 4, in position' fonencounter 6b, 'of theactuator bar 6,' when the latter is' rocked; about its fulcium. Thus each of the rods,-.4l," constitutes a disengageable connector for transmitting the movement; of the baizg;A togone of the key strikers, and except-when they'are under the inliuencer of their respectivemagnets, 5, these rods are biasedoutot connect-ing position by' means of their springsylb." The electrical switch devicesaieso arranged that the magnet- 5 is firstenergized'tddraw the `rod 4,- corresponding to ,any key which. is

chanical connections above noted. In this way, the bell-crank-striker 1 is rocked suiciently to depress the organ key for sounding the note desired.

The amount of angular'swin of the actuating striker 1 maybe varied y changing the osition of a sto rail 11, shown adjustalbly connected wi the top of the housmg, and secured by a set screw 12 at the limit of depression o f the organ key. As the striker ap roaches this limit a paw] 13, biased upwar .by its 'spring 13'^ snaps into osition to engagethevlocbar 14 which, Pike the motor bar 6, is of substantially the saine length as the 4or an key-board. The.

electrical circuit 'may t en Ybe opened without releasing the organ key, so that a sustained note may be produced without dra'inf ing the source of electrical energy, which, for cheapness and convenience, would usually be :f the portable cell type One or more ke, s having been thus held locked in depress position as long as required by the tuner, their release is effected byv clos ing the circuit through a magnet 15, which operates similarly to the .a ove-described magnets, but to move a thrust linkl, provided with an armature 16, and pivoted to a rocker arm 17, rigidly secured to the lock bar 14. The switch-key used for closing the circuit of themagnet 15 is arranged similarly tothe above described switch keys for also closing the circuit for energizing the solenoids 10, 10, so that as soon as the ,thrust link ..16 hasbeen brought into position ,for .en'onnter taf/,its proecting tooth 16b with the upper edge 6" of te motor bar 6, said bar is actuated asv before, but this time to rock the edge 14"- of the lock bar 14 out of engagement with the awl or pawls 13 engaged with it. Thestrikers, 1, being thus released from their depressed position, rock back to their initial posit-ion, allowing the organ keys to follow, and shut oi the pipes which they control.- IIt may be understood that while a separate .thrust rod 4 and magnet 5 are required to correspond with each key of the organ key-board, only a sin gle link 16 a`nd magnet '15 are necessary for release.A A number of organ keys may be successively depressed, and since each is locked in depressed position, a chord may bc thus produced, if desired, Abut all the keys will be released by a single movement of the release switch key. After their operation, the lock bar 14 and thrust link 16 are returned to normal. position by their respective springs 14 and 16 As already stated, the operating keys of the electrical switch-board controlling the device may be made in the form of an organ' manual, so that the operator has nothing new to learn in addition to his knowledge of the organ. This dummy manual may be of considerably reduced dimensions, however, for convenience of use in close @1arters; and even the resemblance to theogan key-board is not essential, since any form of switch-board with the switches marked to show their correspondence to the keys of the organ may be employed. As illustrated, the electrical contactsl are of the fiat sprin ,ty e, this being comparatively cheap, an

e cient enough for use with the small cur rentobtainedfrom a few portable dry cells. None of` the contact elements are secured to their actuating key 18,but are mounted directly Iunder the latter, upon a foundation board, 19, insulating blocks, 20 and 21, being provided at the secured ends, and a spacing block 22 between the free ends of the movable members 23'and 24. The s acng block, 25, is' also provided between tie stationary contact members 26 and 27, to prevent other than the desired contacts. LA release switch, 28, of similar construction, 'is shown mounted separately from the actuating switches' in the front rail 29 of the frame. Since when the contact devices are made as shown, a single movement of the switch key closes two circuits, very slight priorityof contact in one circuit as compared with the other cannot be depended upon to avoid me chanical'confusion in the' actuating mechanism. For this reason, a certain amount of lost motion is preferably introduced in the connections of the motor bar, 6,and conncting thrust bars 4 and 16, so that the I latter .will certainly be drawn downward by their coitrollin "magnets before the motor barrnove( into position .for encounter wah-metete ef said thrust bm has been brought,ii1t"acton;"that is, the operations are rendered concurrentrather than strictly simultaneous, l, v.

At one end, the foundation board 19" is clips' 30, arran cable, and eac properly connecte with some contact member of the switch-board. Coperatin plug pins 31 are similarly are ranged Ian mounted in a removable board 32, and wires from thc respective pins form a cable 33 which is led out from thc board 32 to the key-actuating mechanism mounted, as described, at the organ manual. At this cnd,"thc. cable enters a similar removable board.34, provided with plug-pins 35, to which Ythe respective wires are connected, and which fit into a series of spring contact clips 36,1nountcd on the housing 3 of said key-actuating mechanism, and electrically connected with their respective magnets. Proper connections from the solcnoids 10, l0, and the smaller magnets 5 and 15, with their respective batteries, indicated in the wiring diagram only, complete the list of the parts necessary to the operation of the device.
