DAVID J. HAUSS, OF AURORA, INDIANA.

MUSIC-PLAYER.

Application filed October 23, 1909.

To all whom it may concern:

Be it known that I, DAVID J. IIaUss, a citizen of the United States, residing at Aurora, in the county of Dear-born and State of Indiana, have mvented certain new and useful Improvements in Music-Players, of which the following is a specification.

My invention relates to improvements in electrically actuated music players. One of its objects is to provide improved means to feed the music sheet, to regulate the speed with which the sheet is fed, to stop and start the feed, and to feed the sheet backward at an increased rate.

Another object is to provide improved mechanism to conveniently control the various movements of the sheet.

It further consists in certain details of form, combination and arrangement, all of which will be more fully set forth in the description of the accompanying drawings in which:

Figure 1 is a front elevation of a piano with my improvements attached thereto. Fig. 2 is a diagram of the controller mechanism and electrical connections to said controller and motor. Fig. 3 is a side elevation of the controller. Fig. 4 is a detail of a modification of Fig. Fig. 5 is a sectional detail of the rewinding clutch mechanism. Fig. 6 is a similar view of a modification. Fig. 7 is a sectional detail. of the clutch sh ifti n g mech anism.

In the accompanying drawings A repre sents the piano casing.

B represents an electric motor.

U represents a shaft which is clutched to and adapted to drive the sheet feeding roll. from which the sheet is being fed during the act of producing the music.

I) represents a shaft which carries and is adapted to drive the roll D which. receives the sheet during the act of producing the music.

I) represents a shaft which ismounted concentrically with the shaft 1) and driven slowly from the motor B by means of a worm I) on the motor shaft, a worm wheel Z) 011 the shaft 6 and thence by beveled gear 6 on shaft and beveled gear I) on shaft D. Two spur gears (Z (Z are mounted side by side on the adjacent ends of shafts I) D and motion is transmitted from gear (Z' to gear (Z by means of a pinion (l having a face wide enough to mesh with both gears Specification of Letters Patent.

Serial No. 524,119.

cl and d. The pinion 61 is carried on pivoted frame (Z and is adapted to be shifted into and out of engagement with gears d d by means of a lever d having inclined projections d to shift said frame. Said lever also preferably at the same time serves to open and close a switch 6Z6 controlling the music key circuits.

The opposite end of the motor shaft carries a friction gear 0 which is engaged by a friction gear 0 on a shaft 0 journaled in frame d Shaft 0 carries a sprocket-wheel 0 which by means of a sprocket chain 0* and sprocket wheel 0 on shaft G tends to drive shaft G in a direction opposite to that which it would be driven by the rotation of shaft D. I/Vhen the gears (Z (Z (Z are in mesh the shaft D rotates the music rolls C 2 in the direction to feed the sheet from roll C to roll D and friction gear 0 is out of engagement with friction gear 0. lVhen the gear (l is thrown out of mesh with gears (Z (5 the friction gear 0 is shifted into engagement with friction gear 0 and serves to rotate the music rolls at an increased speed to transfer the sheet from roll D to roll 0.

In the modification Fig. 7 the motor is provided with a pinion C in place of a friction gear and a spur gear 0 carried by frame d is shifted into mesh with pinion 0 and in turn drives spur gear 0" on shaft C to rewind the sheet on roll C. If desired a duplicate set of gears 0! cl (Z may be employed to drive shaft C to rewind the sheet.

The motor is preferably of the direct current type comprising a magnetic field energized by a field coil H, an armature it, a commutator 7a and a plurality of contact brushes iffy.

The motor is controlled by means of a controller preferably comprising two sections J J. The section J is pivotally supported by means of a grooved collar of insulating material which rests between the forked arms of a bracket in which is rigidly supported upon the controller block or base K. The section J is telescopically adjustable within the bore of section J and is splined and prevented from turning within the bore of section J or being completely withdrawn therefrom by a screw 7". The forward or projecting end of section J is downwardly turned to facilitate holding and manipulation of the controller, said section being preferably insulated from section J.

L represent buttons arranged upon the controller block K concentrically about the center L, and upon opposite sides thereof. The block K is of insulating material and has pivoted thereto at the center L a cross bar or switch lever M the opposite ends of which are adapted to contact with diametrically opposite buttons L. Sections of resistance wire Z serve to connect in series adjacent buttons L upon opposite sides of the block K. The bar M has also connected thereto and projecting at substantially right angles a forked arm M, the forked end of which engages opposite sides of a sleeve m of insulating material carried by the section J of the controller.

N N represent contact plates carried by the block K and adapted to be alternately or selectively engaged by the contacts or brushes n a carried by the controller section J. A spring 71 serves to normally hold the controller in position to make contact between the plate N and brush a.

A line 0 connects the lower button L of the right hand series with the contact brush If of the motor. A line P connects the upper button L of the left hand series with the brushes 12- it. A line B connects the plate N with lead screw 1 of the motor, which is in turn connected by line r with one end of the field coil H. Plate N is connected by line S with the lead screw T of the motor which in turn is connected by line 6' with the opposite end of the coil H, and by line It with the contact brush [L of the motor.

U U represent the line wires.

When not in operation the controller section J is telescoped within section J so as to be out of the way beneath the key board. lVhen in operation the section J is drawn forward so that its forward end projects slightly beyond the key board. The sheet rolls being adjusted to position, and the main line switch V closed to supply current to the motor, and brush a and plate N being in contact, the motor will start to rotate and slowly feed the sheet from roll 0' to roll D The speed of the motor can be varied within the limits required by moving the controller lever J to the right or left, a movement to the right increasing and to the left decreasing the motor speed. hen it is desired to stop the motor the controller lever J is turned upon its axis to break the contact at n, N, and to make contact at n N which. serves to convert the armature from a motor to a generator with theresistance Z in circuit and a separately excited field, which acts as a brake upon the armature and stops its rotation instantly. After the sheet has been fed from roll 0 to D the lever 6Z is shifted to throw gear (Z out of mesh with gear (Z, whereupon the friction gears c 0 drive the roll C at increased speed in the reverse direction to return the sheet to roll G.

In the modification Fig. 4C the plates 2, 3 corresponding to the plates N N of Fig. 3 are located above and below the controller lever 4-, and to stop the motor the controller lever is lifted vertically to break contact between the brush 5 and plate 2, and to make contact between the brush (3 and plate The mechanism herein illustrated and described is capable of considerable modification without departing from the principle of my invention.
