MOTOR FOR SELF-PLAYING ORGANS.

To (tZZ whom it may concern.-

Be it known that I, CHARLES WARREN, musical instrumental expert, of the city of Guelph, in the county of Wellington, in the 5 Province of Ontario, Canada, have invented certain new and useful Improvements in M0- tors for Self-Playing Organs, of which the following is a specification.

My invention relates to that class of pneu- I0 matic organs which may be played either from the ordinary keyboard or automatically by means of a tracker-board and perforated music-sheet; and the object of the invention is to provide a silent and practically frictionless means for winding and rewinding the musicsheet.

In order that the invention may be fully understood, I will describe the same by reference to the accompanying drawings, in which- :0 Figure l is a general perspective view of the exterior of my organ, showing the casing broken away to exhibitgenerally the parts involved in my invention. Fig. 2 is a sectional view showing the disposition of the parts. Fig. 3 is a similar view from the reverse side.

In carrying out my invention I employ a vacuum-chamber at, extending longitudinally and communicating with the tracker-board b by tubes 0, communicating alternately with diaphragms din the front and back walls of the vaouum-chamber,valves e,covering openings 6, connecting the chamber ct with the outer air, being adapted to be operated by 5 the diaphragms d in the usual well-known manner.

4 is the main spindle of the motor. As such motor forms a subject-matter of a separate application it is not necessary in this speci- 4o fication to describe it.

F is the gear-wheel on the driving-drum for the music-sheet.

Gris the spindle of the rewinding-drum for the music-sheet.

. H is a supplemental spindle which is sup- K is a groove-pulley which is loose on the spindle H and is connected by the belt 70 to the pulley G on the spindle ot' the rewindingdrum. One of the bearings I is a forked bearing and extends into a groove in the hub of the pulley K, so that it will prevent such pulley from longitudinal displacement on the spindle, and thereby keep it opposite to the pulley G on the spindle G. Lis a sleeve fastened by a set-screw L on the end of the spin- 6o dle H. The end of the motor-shaft 4 extends into the end of the sleeve L and is connected thereto by a pin 4 Which extends into the longitudinal slots L diametrically opposite to each other. These slots permit of the longitudinal movement of the sleeve on the motorspindle I, for a purpose which will hereinafter appear. On the opposite end of the hub of the pulley K, I provide a laterally-extending pin K.

M M are the collars, secured on the spindle II, the one collar M being provided with a pin M, which is designed to be brought into con tact with the pin K by the means I shall now describe. The stop 1!. is connected, by means of the block to, to the bell-crank rod uawhich extends through the end of the link t and through a slot in the block. The stop M has also a block u which is provided with a notch, into which extends the bent end of the rod 10 which is journaled in suitable bearings in the upright 11?, attached to the frame. The upper end of the rod 10 extends in between the collars M M on the spindle H.

It will thus be seen that when the stop is closed, as shown in Fig. 1, the pinion J meshes with the wheel F, while the reliefvalve 4" would be closed and the valve q removed from over the opening 0 (See Fig. 3.)

It will of course be understood that the valve (1 is for the purpose of making or cutting off the communication between the pneumatic action and the exhaust-bellows. The relief-valve r is opened at the same time that the valve q is closed by reason of the rod at- 5 tached to the valve. This opening of the relief-valve 0" opens the communication of the pneumatic action with the atmosphere practically simultaneously with the closing of the valve q, so that the automatic action is inop- 10o erative instantly and there is no danger of any notes being sounded after the stop has once been drawn.

The organ is arranged so as to play automatically by means of the tracker-board and perforated music-sheethereinbefore referred to, the wheel F being of course driven by means of the pinion Jon the end of the spindle H, which is connected to the end of the motorspindle 4. Immediately the stop u is pulled into the position shown in Fig. 3 the organ is set so as to be played manually. At the same time, however, the spindle H is shifted longitudinally, so as to carry the pin M against the pin K, and if the motor-stop N is pulled 'out, so as to create a vacuum in the motortrunk A, the motor-shaft 4 being in motion will communicate such motion by means of thepin M to the pulley K, and thereby rewind the music-sheet. Should, however, the stop N be closed, as indicated in Fig. 2, communication is shut off by the valve N, which in the former case is open. Such valve N is connected by the rod N to the upright N which is connected by the link N to the crankrod N which extends into a slotted block N on the stop N.

When it is desired to play the instrument manually, the stop N will preferably always be closed, as of course it is not necessary to have the motor running.

What I claim as my invention is 1. In a pneumatic organ, the combination with the motor and. spindle thereof and the music-sheet and driving-drum therefor, and

gear-Wheel on the spindle of the driving-drum, of the supplemental spindle provided with a gear-pinion at one end meshing with the gearwheel on the driving-drum, a sleeve secured on the opposite end provided with longitudinal slots extending lengthwise over the end of the motor-spindle, and a pin extending through the motor-spindle and the slots whereby the supplemental spindle may be moved longitudinally to throw the pinion in and out of gear without disturbing the operative relation between the two spindles, as specified.

2. In a pneumatic organ, the combination with the vacuum-chamber with its passages, valves, pneumatics and tracker-board combined and arranged substantially as shown, of a motor having a plurality of pneumatics and a spindle operated from the same, a supplemental spindle connected to the end of the motor-spindle and a pinion located on the end thereof and meshing with the wheel on the driving-drum of the perforated music-sheet, the stop, means operated from the stop for throwing such spindle longitudinally so as to remove the gear-pinion from engagement with the gear-wheel and means also connected to the stop for simultaneously opening the relief-valve and closing the trunk and pneumatics to the vacuum-chamber as and for the purpose specified.

CHARLES WARREN.
