arness.

To all whom it may concern: I

Be it knownthat I, FRANK H. ADAMS, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Repeating and Stopping Attachments for Phonographs, 0*:

full, clear, and exact description.

This invention is an improvement upon the repeating and stoppingattachment for phonographs which forms the subject matter of my pending application, Serial No. 859,271, filed August 31, 191-1.

One object of this invention is to provide such repeating and stopping attachments with means by whicha record may be repeated indefinitely, or any desired number of times, and which will automatically stop the phonograph when the record has been played the required number of times.

Another-object of the invention is to so construct such repeating and stopping attachments that a person having no particular mechanical skill may be sure to apply the attachment in proper operative relation to the cooperating parts of the phonograph.

The invention consists in the construction and combination of parts shown in the drawing and hereinafter described and definitely pointed out in the appended claims,

In the drawing Figure 1 is a plan view of a disk phonograph with this invention applied to it; Fig. 2 is a sectional front elcvation of the parts shown in Fig. 1; Fig. 3 is a bottom view of the track arm; Fig. i is a full size front elevation of the invention attached to a phonograph,partsof which are shown in section; Fig. 5 is a plan view of the base plate of the atta-lnnent when the track arm is disconnected therefrom; and Fig. 6

is a sectional elevation substantially in the plane of line 6-0 on Fig. 5.

The parts of the phonograph with which the attachment cooperates require no changes in construction. The parts of the phonograph shown in the drawing include the driving spindle 2 which projects vertically up through a horizontal partition board 1, which is a part of the phonograph cabinet; a record-supporting turntable 3 which embraces and has a driving connection with the spindle but is detachable thereabout a vertical axis;

to said tone arm; and the sound box 4 carried by said U-tube. v

The attachment, as shown, is like that which forms the subject matter of said prior application, in that it includes a trackarm 10 which is pivoted on a horizontal axis to a fixture located to one side of the turn-.

table so that it may oscillate up and down about said pivot; and means whereby when a record has been played the free end of the track arm. will be raised to cause the tone arm of the phonograph to return to the starting position and then lowered to free said tone arm from restraint and to allow the needle 5 to enter the groove of the record B. These means may 13, detachably fixed to the spindle which r tates the turntable, and provided with the double spiral grooving; and the dog 14 movably mounted on the track arm, adapted for engagement with the grooves in said include the spind e standard- As fully described in said prior application, when the needle reaches the end of the playing groove in the record, the needle or some other part such as a downwardly projecting finger 14 movable with the sound box engages a laterally projecting part 149 of the dog and causes a spring 14E (see Fig. 3) to shift one of the jaws of the dog into the elevating groove of the spindle, causing the track arm to be elevated. As the track arm is elevated it engages a roller 1 L movable with the sound box, lifting the needle clear, of the record and swinging the U-tube about its axis when the sound box as a whole and the parts carried thereby move by gravity to starting position. When the dog reaches the upper end of the spindle it is rocked to its former position by a cam 14 so as to cause. the other jaw of the dog to enter into the lowering groove, whereupon the track arm is gradually lowered until it rests as before on the base of the grooved spindle. But any other suitable means for raising and lowering the track arm, to cause the return of the tone arm to its starting position, may be employed.

The application to a phonograph of the attachment shown and described in said prior app Ration requires considerable mechanical skill, because said attachment has to be located in working relation to the folviz: the tone arm, the turntable and its spindle, and the turntable brake. object of this-invention is to render it easy As before stated, one

- crated by the ment to a. phonograph.

turntable brake lever 8 is mounted on the attachment, and in proper relation to the parts thereof which control its movement; and the supporting member for the track arm is made in the form of a base plate 9 having in .one end a hole 9 adapted to fit loosely over the spindle 2, so that when said base plate. does embrace the spindle and rests upon the horizontal partition board 1 below the turntable, the hinge for thetrack arm will be properly located with respect to the spindle and turntable. Therefore, the

person. applying the attachment to 'thephonograph has only to exercise his judgment in so moving the outer end of the base plate that the brake will properly engage the turntable; and having properly located the attachment with this purpose in view, the attachment may now .be permanently fastened to the partition board 1.

The outer end of the base plate 9' is turned up to form the flange 12, and it is to the upper edge of this flange that the track arm is hinged.

The brake-lever 8 is, as stated, pivoted to the base plate. This is accomplished by means of a curved pivot stud 15 which may be formed integrally with the upturned-rear flange 16 of the base plate 9. This stud goes rather loosely through brake lever, and, therefore, said lever may not only swing in a horizontal plane toward and from the turntable, it may also be moved up and down sufficiently to enable it to cooperate with the restraining devices to be presently explained. This brake lever is under the influence of a spring 17 tending to move it toward the turntable, and it is provided with an arm 8*,

adapted -to engage the edge of the turntableand apply braking pressure thereto.

Associated with this brake lever is an escapement device which is to and fro,'. 6., the up and down movements of the oscillating track arm, by which this brake lever is held away from the, turntable, but is released and allowed to come into. braking engagement therewith after the record has been played any desired number of times, within the capacity of the device. I

In the construction shown, provision is made by which the record may be played one, two or thrce times, as desired, and then the phonograph automatically stopped.

In the particular construction of this escapement mechanism which is embodied in the device shown in the drawing, a flange 19 is turned up along the front edge of the base plate 9, and in this flange is a hole 19 through which the free end of the brake disengaged from a hole 8 in thebut the free end of adapted to be op? terms? "is nearest the turntable is formed with a plurality of stepped shoulders or, b, 0, and below them'a notch 20, and below that a shoulder 22. When the brake levertengages shoulder 22 it will be held out of braking engagement with the turntable until it is manually this shoulder. When, however, the brake lever is in line with the notch 20*, that lever, actuated'by its spring, may move into braking engagement with the turntable and thereby stop its rotation. If

the brake lever is in engagement with. either of the shoulders a, b, and c, it is likewise held out of engagement with the turntable.

On the under side of the track arm 10 is a depending bracket 20 which lies close to and behind the flange 19. On that edge of this bracket which is farthest from the -turntable are a plurality of stepped shoulders cl, 6, f, placed substantially as shown with respect to the shoulders at b, 0, so that the shoulders on the bracket and the shoulders on the flange will cooperate in pairs. That is to say, the shoulder d, for example, is at a slightly greater distance from the. turntable than is the associated shoulder a, and

is in a slightly lower planewhen the track arm is down; and is also below a horizontal surface a leading off from the upper shoulder a. The shoulder e occupies a corresponding relation to the associated shoulder b, and-the off-leading horizontal surface I);

"and the shoulder f occupies a corresponding position relative to the shoulder '0 and its ofi-leading surface 0.

Likewise, the shoulders a, bra, and d, e,.

flare slightly undercut, and the corresponding edge of the brake lever is also undercut as at 8this undercutting being .for the purpose of insuring that the parts shall operate in the manner now to bedescribed.

In starting the phonograph, the track arm will be in its horizontalposition shown in Fig. 2. In'case it is desired that the record shall 'be played three times, the brake leverwill be drawn back and moved up into engagement with the shoulder d, as shown in Fig. 4. When the record has been played once the track arm will be raised as by the mechanism shown in the prior application, or other suitable mechanism. As it goes up, the brake lever will be carried up into contact with the associated overlying surface a, by which it will be pushed out of engagement with the shoulder d, and will be allowed to move into engagement with the shoulder a. Then, when the track bar descends, the bracket 20 will engage the lever progressively from shoulder e to shoulder b and then to shoulder f on the next to and fro movement of the brake arm, and then from shoulder f to shoulder c, and thence into notch 2O" n the third to and fro move-' ment of said track arm.

As before stated, when the brake lever entors notch it will apply braking pressure to the turntable and stop it,the record in the meantime having been played three times. If it is desired to play the record only twice the brake lever would be initially placed in contact with shoulder e. If once only, it should be placed in contact wlth shoulder f.

It is to be understood that if one wishes to play the record indefinitely he will place the brake lever in engagement with the shoulder 22.
