ranged to be operated electrically, the object of the invention being to produce a multiple tracker board mechanism for the purpose wherein one mechanism may be thrown into or out of action, and another simultaneously likewise thrown out of or into action and means whereby the one mechanism may be independently operated to position the music sheets thereon while the other mechanism is in operation. The demand for this type of v proved 1I1V81'll31011 consists primarily of a mechanism has been greatly increased by the present popular use of automatic musical instruments in connection with moving picture theaters and other showhouses where it is desired to play different pieces of music to fitthe different scenes being enactedon the electrically operated and controlled musical instrument canbe readily adapted for this purpose. p

While the invention, as at present advised, is especially adapted for use in connection with pipe organs, still in practice it could as well be adapted for use in other connections; For the purpose of the present illustration however, we will consider the same as used in place of or in connection with the keyboard used in connection with pipe organs for operating the various valves and stops, the present invention especially relating to their operation by electrically controlled means. a

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects I accomplish by means of.

such structure and relative arrangement of the parts as will fully appear by a perusal 5 of the following'specification and claims.

means at their ends for projecting through the perforations in such a manner as to avoid.

any possibility of catching and tearing the sheet 9 when passing into or out of a perforation. 1

Between the rollers 5 and 6 are members 16, 17, 1s, 19, 2o, 21, 22, 23, and 24 of similar structure to the members 7 to respectively.

- My improved invention" embodies especially the following features, namely:

A forward operating mechanism for the music sheets wherein one sheet is operated forward for playing the musical instrument 7 wh1le the other one 1s 1n lnoperative position; a means for rewinding the inoperative while the other one is in inoperative position, is

the numeral 25 designates the shaft for oper ating the roller 4 and the numeral 26 the shaft for operating the roller 6. On the shafts 25 and 26 are gears 27 and 28 respectively meshing with pinions 29 and 30 mounted on shafts 31 and 32, this latter mechanism being for the purpose of reducing the speed.

Keyed to -the shaft 31 are two sprocket wheels 33 and 34, the sprocket wheel '33 being of a larger size than the sprocket wheel 34,

and similarly, on the shaft 32 are sprocket 5 wheels 35 and 36. The sprocket wheel 34 is connected by a chain37 with the sprocket wheel 38 turnable on the shaft 39 driven b the driving motor 40, such sprocket 38,

having a clutch face 41. A chain 42 connects the sprocket 34 with the sprocket 43 turnable on the shaft 39v and having a clutch face 44, all for a purpose as will appear. The numerals 45, 46, 47, 48, 49 and 50 indicate parts on the other mechanism similar to the parts 37, 38, 41, 42, 43 and 44 V The numeral 51 designates a selecting lever mounted at a point adjacent the keyboard 1 and arranged to throw either the roller 4.

or 6 into operative position to advance the corresponding music sheet and to simultaneously discontinue the operation of the other roller and its music sheet. plishcd by means of the following structure, namelyz." I

A link 52 connects the lever 51 with the bell crank 53 which bell crank is connected at itsend by a link '54 with bell crank 55.

Such bell crank 55 connects at its other end with a push rod 56 common to two levers 57 and 58. The lever 57 is connected with a collar 59 slidably keyed to the shaft 39 and having a clutch 60 arranged to engageth'e" clutch face 41. The lever 58 is connected with a collar 61' keyed to the shaft '39 {and provided with a clutch 62- arranged for engagement with the clutch face 47.

' sprocket 33 and the shaft 31.

This is accom- Assuming that the roller 4 is to be thrown into operation'to draw the music sheet off the roller 3 and over the roller 7 the lever 51 would then be moved to the left, which through the medium of the link mechanism described will push the push rod 56 to the left and operate' the lever 57 so as to move the clutch 60into engagement with the clutch face 41 on the sprocket wheel 38. With this operation the push rod-56 will pull'on the lever 58 so as to move it to that position in which the clutch 62 will be entirely free from any possibility of engagement with the clutch face 47 on the sprocket 46. When the clutch 60 is engaged with the face 41, the shaft 39 being rotated by the motor 40, this will rotate the sleeve 59, sprocket 38, and through the medium of the chain 37, will rotate the pinion 29 will drive the gear 27, shaft 25 and roller 4 to advance the music sheet 9.

When the music sheet 9'is being advanced over the roller 7 by. means of the operation just described it becomes necessary with such advancementto make electrical connections between the roller 7 and the fingers 15, so that as the fingers 15 contact with the roller 7 through the perforations in the sheet 9, suit-' Thus the able mechanism may be thrown into opera- 1 tion to playthe musical instrument, and this is accomplished as follows:

lV hen the lever 57 is thrown over to engage the clutch 50 with the clutch face 41 a contact point 63 on the said lever 57 is moved into engagement with the switch blade 13 whereupon a circuit can be completed as follows: A wire 64 connects the point 63 with aeource of electrical energy 65 which may be of any desired or adaptable kind.

Another wire 66 leads from the source 65 to an electro magnet 67 from which another wire 68 leads toone of the fingers 15. The lingers15 of course are insulated from the beam 14.

The electromagnet 67beingthus energized by the closing of the circuit attracts the point 69 on the operatingmechanism 70 of the musical instrument. No connection is shown between the member 7 O and the valves and stops of the musical instrument since this structure is common. It is of course understood that there is a separate circuit for each one of the fingers 15, each energizing a similar electroma-gnet which in turnattracts a member of the the same construc tion the member 70, such members 70'be' ing operatively connected to actuate the pipes of the organ in any manner common to the art; a

hen it isdesired to cease taking up the sheet 9' on the roller 4 and to take up the sheet 18 on the roller 6,the lever 51 is moved to the right. This acts on the lever '57 to throw the clutch 60 out of'engagement with the clutch face 41 and also'breaks thecontact between the points 63 and 13. At the same time the lever 58 is actuated to move the clutch 62 into engagement? with the clutch face 47 and the points 72 and 22 into contact with each other. This, through the mechanism which corresponds to that mechanism described for throwing. the roller 4 into action, throws the roller 6 into action and advances the sheet 18. The fingers 24 then act the sameas described for the fingers 15 to complete the'following circuit, namely: n

From the source of electrical energy. 65 through the wire 66, electromagnet 67 wire 68, wire 68 to one of the'fingers 24 thence through the roller 16, arm'17, point 20, wire 21, point 22, point 72, and wire 73 back to the source 65 thus throwing the electro-' magnet 67 into action and causing it to operate the members 69 and 70 as in a manner previously described. j V By moving the lever 51 to vertical position the levers 57 and 58 will be so posiv tionedthat none of the mechanism'for op erating the musical instrument will be in driving relation with the shaft 39.

WVhen the roller 4is in operation and the roller 6 is not in operation for advancing the sheet 9 to operate the musical instru-' ment, or vice versa 01' when neither of said rollers is being so operated, and it is desired to reposition the sheet 9 or the sheet 18 on the rollers 4 or 6 without rendering any music therefrom but merely for the purpose of bringing another selection into position ready to be played, this is acomplished by means of the following structure, namely:

The numeral 74 designates a small lever positioned adjacent the keyboard 1 and connected by a link 75 with a bell crank 76 which in turn is connected at its other end by a link 77 with another, bell crank 78. This latter bell crank 78 is pivoted to a push rod 79. On one end of the push rod 79 is pivoted a lever 80 connected with a sleeve 81 slidably keyed to the shatt 39 and having a clutch 82 arranged to engage the clutch face 44 of the sprocket wheel 43. On the other end of the push rod 79 is connected a lever 83, which lever is connected with a sleeve 84 slidably keyed on the other side of the shaft 39 and providedwith a clutch 85 arranged to engage the clutch face 50 on the sprocket 49. By throwing the lever 74 to the left, this, through the medium of the link mechanism shown, will move the push rod 79 to the right and thus actuate the lever 80 to move the clutch 82 into engagement with the clutch face 84 which will place the sprocket wheel 43 into driving relation with the shaft 39. This, through the medium of the chain 42 and sprocket wheel 34, will drive the shaft 31, pinion 29, gear 27 shaft 25 and roller 4 so as to rotate such roller 4 in its forward direction. Due to playing purposes only.

the relative size of, the sprockets 43 and 34 the roller 4 will be rapidly turned which will quickly move the sheet 9 over the roller 4 to any desired positionand-this canbe accomplished while the roller 6 is being operated: to actuate, the musical instrument.

:VVh'enthe clutch 82 is engaged with the clutch face 44 the clutch 85 is simultaneously moved so as to be out of any possible engagementxwith theclutch face 50 so as not to affeet the opposite mechanism, but when the roller 4 is being operated for playing the musical instrumenttheroller 6 can likewise be moved to position the sheet 18 thereon merely by moving the lever 74 to the right; or by having the lever 74 in vertical position neither of the clutches will be in engagement with'its corresponding clutch face so asto allow of the operation of the mechanism for V7 hen it is desired to rewind the sheets- 9 or 18 on their rollers 3 and 5 when the cor- V responding rollers 4 or 6 are not in action this can be accomplished by means of the following structure viz: A lever 86 is fulcrumed adjacent thekeyboard 1 and is connected by a link 87 with a bell crank 88, the other end of said bell crank being connected by a link 89 with a bell crank 90, which bell crank 90 is connected with a push rod 91 connected at its ends with levers 92 and 93 respectively. The lever 92 is connected with a sleeve 94 slidably keyed on a shaft 95 and provided with a clutch 96, while the lever 93 is connected with a similar sleeve 97 slidably keyed on the shaft 95 andprovided with a clutch 98. Secured on the shaft 95 is a sprocket wheel 99 connected by a chain 100 with a sprocket wheel 101 keyed to the shaft 39 whereby theshaft 95 rotates with the shaft 39. On the shaft 95 adjacent the sleeve 94 is a sprocket wheel 102 having a clutch face 103 which sprocket wheel 102 is connected by a chain 104 with a sprocket wheel 105 keyed to a shaft 106 which carries the roller 3. Similarly keyed to the shaft 95 adjacent the sleeve 97 is a sprocket wheel 107 having a clutch face 108, such sprocket wheel 107 being connected by a chain 109 with a sprocket wheel 110 keyed to a shaft 111 which carries the roller 5. v

If it is desired to rewind the sheet 9 the lever 86 is moved to the left which, through the medium of the link mechanism described moves the push rod 91 to the right and throws the lever 92 so that the clutch 96 engages the clutch face 103 and operates the sprocket wheel 102, which, through the medium of the chain 104 advances the sprocket wheel 105 and the shaft 106 to wind the sheet 9 upon the roller 3. With the reverse action the clutch 98 is thrown into engagement with the clutch face 108 and operates the sprocket wheel 107 which,through the medium of the chain 109 operates the sprocket wheel 1 10 to operate the shaft 111 to Wind the sheet 18upon the roller 5;

The motor 40 is driven by a suitable connection with the source of electricity 65 and the time in which the music is played is controlled by regulating the speed of the motor with a resistance lever 112 which con trols a suitable resistance 113 of any desired type. i v i 3 L W hile-this specification sets forth in detail thefpresent and preferred construction of the device, still in practice such deviations from such detail may be resorted-to as do not form a departure from the spirit of the invention as defined by the appended claims.
