ELECTRIC GUIDING MECHANISM.

Specification of Letters Patent.

Patented Nov. 30, 1920.

Application filed January 19, 1917.v Serial No. 143,225.

To all whom it may concern:

Be it known that 1, JAMES OCo vNoR,a citizen of the United States, and a resident of New York, borough of Manhattan, 1n the county of New York and Stateof New York, have invented certain new and useful Im provements in Electric Guiding Mechanisms, ofwhich the following is a specification. I

This invention' relates to electric guiding mechanism for a sheet or web traveling over an a paratus, in relation to which it is desirable that said sheet travel with the least possibleedgewise deviation. The ob ect of my. improvements is to provide a simple device, electrically actuated and electrically controlled for correcting any tendenc 1 in said sheet to deviate laterally relative y to said apparatus.

With this end in view myimprovements comprise features which I have chosen to illustrate as applied to the restorationof the normal relation between the note-sheet and tracker of a player-piano and these features are shown in their preferred embodiment in the drawings accompanying this specification, wherein Figure 1 is a of my improved device. Fig. 2 is a fragmentary plan view showing a portion of what is shown in F i 1. Fig. 3 is a similar plan view to that of ig. 2 and showing another form of my device.

Referring now particularly to Fig. 1, tracer 2 is rigidly mounted in side frames 3 an 4. Above said'tracker, roll 5, carrying note-sheet 6, is pivotall slidably mounted in said side frames, an below tracker 2 take-up roll 7 is pivotally mounted, said roll 7 being eflicient when rotated to draw sheet 6 over the face of tracker 2.

Fixed to the outboard face of frame i and in line with roll 5 is magnet 9, preferably in the form of a solenoid. For coaction with said solenoid, armature 11 fixed to one end said tracker.

front elevation of one form 7 An electric conductor 24: connects contact member 130 with battery 22, battery 22 with solenoid 9 and solenoid 9 with contact member 19, so that when the sheet deviates to the right and engages contact 130 and moves that contact into engagement with contact 19, an electric circuit will be established in solenoid 9, whereby armature 11 and roll 5 will be drawn to the left, thereby correcting the deviation of the note-sheet relatively to The left hand end of roll 5 is constantly urged to the right by spring 37.

In Fig. 3 is an arrangement whereby tracker 2 is mounted for endwise movement instead of 170112 and whereby another form of sheet-engaging contact member is employed. Therein, contactmember 15 is pivoted in tracker 2 and has an arm 16 for engagement with the edge of sheet 6, and another arm 17 for engagement, one at a time, with

opposite contact members

20 and 21 fixed relatively to said tracker. Said arm 16 is constantly urged toward sheet 6 by spring 31. In this arrangement solenoids 8 and '9 are arranged side. by side. In the arrangementof Fig. 3, when sheet 6 is absent from tracker 2 arm 17 lies continually in engagement with contact 20, whereby the current from battery 22 would be wasted. Therefore I'provide a circuit breaker, and which may be employed in other casesif desired, to

break the circuit when the sheet is absent from the tracker. This device may comprise plunger32, mounted for movement transversely of the tracker and normal to the sheet, and having a contact 33 at its lower end for engagement with contact 34, i said contacts being connected in circuit with batteryv 22. The upper end 35 of plunger 32 is positioned tobe depressed by sheet 6 when that sheet is'in place on tracker 2, whereby contacts 33'and 34 arecaused to engage, and complete the electric circuit when. contact member 17 engages either of

contacts

20 and 21. i

It will thus be seen that, by my improved device, electrical means simple in construction and highly adaptable to a variety-of details of environment, are, provided for restoring the normal relation between the sheet and tracker when that relation is disturbed;

I claim: V 1. The combination of a tracker and a roll, one of said parts being relatively movable longitudinally with respect to the other, a note-sheet on said roll, means for drawing said sheet over the tracker, two contact members fixed relatively to said tracker, a
