Specification of Letters Patent.

Patented A110. 30,1921.

Application filed October 8, 1920. Serial No. 415,597.

Stops, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to sound-reproducing machines, and has particular reference to stop mechanism for automatically arresting rotation of the turn-table and its superposed record 'at any predetermined point.

The present invention is any improvement upon andan advance over the particular device disclosed in my cao-pending application filed May 8, 1920, Serial No. 379,854.

While the structure of that application has,

in practical use, been determined to be eflicientand useful; nevertheless, it has been found that the improvements herein described and'claimed make for a better and more certain operation of the device, and result ina simplilied construction.

Briefly, it may be explained here that the structure of my said application includes a stop mechanism which comprises a pointermcchanism, a brake-device connected with and settab'le by the pointer-mechanism, a trip-mechanism connected to and for actuating the brake-device and involving a rotating-disk-member on the tone-arm and engageable by a component'of the trip-mecha-,Y

msm.

An object of the present improvement is the provision of means whereby resetting of the stop-mechanism may be effected without (as in the structure of my said companion application) removing the pointermechanism from its Vpredetermined position to relock the device when it is desired to replay a certain record..

A' further object of the invention is the elimination of the aforementioned rotatingdisk-member of my companion case and which disk is mounted on the tone-arm of the phonograph for contact with the tripping means, this elimination thereof obviating` the necessity of drilling holes in the tone-arm to fasten the disk thereto.

A still further object of the invention is the provision of means for insuring a more positive stopping of the turn-table and its superposed record by providing for agreater amount of leverage in operating the stop when the machine is playing records with hill-and-dale grooves.

Other objects and advantages will be apparent from the following description.

In order `that the'invention may be more readily comprehended,'both as to the manner of its application to a phonograph and as toits construction, I have shown in the accompanying drawings one embodiment thereof.

In these drawings: p

Figure 1 is a view in top plan of one embodiment of my invention; y

Fig. 2 is a view in front elevation thereof; y Fig. 8 is aY fragmentary sectional view, in side elevation; and

Figa is a detailed view, Vin perspective,

of a portion of the apparatus.

Referring to these drawings, the numeral 1 designates the casing of a sound-reproducing machine of any appropriate type or construction, which is provided with the usual turn-table 2 for supporting the phonographrecord 8 having grooves 4, and a tone-arm 5 carrying a reproducer or sound-box 6.

Encircling the tone-arm 5 is a supporting or bearing structure, marked A, which comprises a pointer-supporting member or ring 7 formed with an upstanding portion or collar 8 which is adapted to be readily secured to the tone-arm 5, as by screws 9.

Carried by the supporting-member 7 is av pointer-sustaining extension or arm 10.

` Preferably 4and as shown, the collar 8 of the ring 7 has associated therewith a movable trip-carrying member or ring 15 provided with an outstanding member-supporting element or plate 16. livotally secured to the plate is one `member 18 of a toggle, the other member 19 of which turns on a pivotwasher 2O carried byia pivot-post 21 upstanding from the arm 10. Integral with or rigidly: secured to the member 19 of the toggle is a limit-setting member or pointer 22 which is settable by the operator at different positions over the record to regulate the mechanism for stopping the turn-table 2 at any predetermined point, and which is provided with a downwardly-projecting portion 22a.

Depending from the pointer 22 is a boss 23 forming `a connection between the togglemember 19 and the pointer 22. The pointer and toggle-member 19 pivot' on a screw 24 threaded into the arm 10.

Depending from the projection. 16 and near the inner portion thereof is a biurcated stud 25 in which is pivotally mounted a supporting or bearing structure, marked A, which comprises a trip-sustaining member 26, movement of which is controlled by a spring 27. Upstanding from the member 26 is an arm engaging trip 28 which extends through an` aperture in the plate 16 and which trip is adapted to be engaged by the traveling tone-arm 5. The trip 28 is provided, at its upper portion, with a sett-able element or extension 29, pivoted at 30, and

positionable into the path of movement of.

the traveling tone arm so as to be engaged thereby when set, and this is adapted for use when playing different makes of records. It has been found in actual practice that records with hill-and-dale grooves therein require a strong braking action to insure positive stopping` of the turn-table while records with laterally-cut grooves can be positively arrested with a weaker braking action. To accommodate the stop for machines playing records with either the laterally-cut or hill-and-dale grooves, 1 have provided the trip 28 with its pivoted extension 29. Then playing the laterally-cut record, the extension 29 is adapted to be disposed in a vertical position for contact with the lower portion of the traveling tone-arm. For the purpose of arresting a machine playing a record with hill-and-dale grooves, hoi ever, the extension 29 is turned on its pivot 80 and brought into the position shown in full lines in Figs. 2 and 3. 1n this way the traveling tone-arm is engaged by the eX- tension somewhat sooner than when the eX- tension is in a vertical position and set to stop a laterally-cut record; consequently, this earlier contact with the tone-arm advances the instant of engagement of the brake-member (hereinafter to be described) with the turn-table to effect its earlier operation, which, in practice, has been found dcsirable when playing records with hill-anddale grooves.

Normally, the spring 27 has a tendency to move the trip-sustaining member toward the underside of the plate 1G, and mea-ns (presently to be described) are provided for varying the extent of movement ot the member 26. 1t will be understood, ot course, that the position of the trip 28 is such as normally to be in the path of tra-vel of the tone-arm as the same moves across the record in order that it may engage the trip and operate the parts, as will presently be described. The tree end of the member is provided with a catch 31.

Pivotally mounted on the underside of the plate 16 is a brake-member, designated generally by the reference-character 32, and which is of hammer-like form. This brakemember is provided with an engaging-element or hammer 33 adapted, when the trip is actuated, to contact with and arrest rotation of the turn-table. The hammer is, preferably and as shown, provided with a `facing of rubber, telt, or other resilient material 311 which aids in arresting rotation of the turn-table. Disposed at an angle to the hammer and formed as a part thereof is an extension 35 provided with a beveled portion for the purpose of engaging the catch 31 and holding it against movement until the tone-arm is brought into Contact with the upstanding` trip. A spring 37.- secured, as by a screw 38, to the underside of the4 plate 16S- bears against the brakemember and is adapted, when Vthe trip is released, to force the hammer into engagement with the turn-table.

Means are alsoprovided for manually resetting the stop and, as here shown, this comprises a ringer-piece 39 secured to the extension 85 and passing through an elongated aperture 10 in the plate 16. This manual resetting-device is particularly adapted for use when the operatorV desires to replay the record then in position on the turn-table. Ordinarily, to reset the stop for playing the record, the pointer 22 is brought to a position to clear the turn-table so that the record may be removed therefrom. This movement of the pointer throws the plate 16 and the attached brake-mechanism against the edge of the turn-table, causing the hammer to be automatically reloclred. Should the operator desire to replay the record, he does not change the position of the pointer over the record, but resets the brake by means of the lingerpiece 39.

Means are preferably provided for varying Vthe extent of movement of the brakemember 32; and, as here shown, this comprises a screw l1 threaded through the plate 16, adjacent the trip 28, and adapted to engage the brake. By raising or lowering this screw, the time of. release of the hammer can be varied.

Means are also provided for maintaining the movable ring 15 in proper operating position and, as here shown,'this comprises a ring-element 112 secured, as by screws 13 threaded therethrough, and engaging the collar 8 of the suiiporting-ring 7.

For the purpose Vot maintaining the tripcarrying ring 15 is spaced-apart relation to the base of the ring 7 and to the ring-element l12, suitable washers 411 are inserted therebetween, as shown.

Operation: After the record has been placed on the turn-table, the pointer 22 is brought to the position over the record where it is desired to trip the brake. By

moving the pointer in this manner, it will be observedthat, through the iconnected lever arrangement 18 and 19, the plate 16 with the upstanding trip 28 will be moved to the left. If the record to be played is provided with hill-and-dale grooves, the pivoted extension 29 is turned down so that it will engage the traveling tone-arm sooner than when the extension is in an upright position and, consequently, advance the instant of engagement of the brake-mechanism with the turn-table to effect its earlier operation. When the tone-arm has reached that point in its travel where `it contactsy with the upstanding trip, the pressure thereof causes the trip to yield sufficiently to release the catch 31, permitting the hammer 33 to be forced, by means of the spring 37, against the turn-table and, thus, bring the same and its superposed record toa complete stop. f i If it is desired to place another record on the machine, the pointer 22 is turned so that it will permit withdrawal of the record then on the turn-table. In so moving the pointer, the projection 16 is, as above pointed out, carried to the right, forcing the hammer 33 against the turn-table and thus causing it to be automatically relocked by pressing the extension 35 on the hammer and forcing the beveled portion thereon to ride over the catch 31. Thus, it will be seen that the stop is automatically re-set. After the new record has been placed on the turntable, the pointer is again brought to the proper position on the record for operation. In moving the pointer in this manner, the plate 16 and its attached brake-mechanism are moved out of engagement with the turntable, which permits the same to revolve, as understood. However, if the operator desires to replay the record then in rposition on the turn-table, the brake can be manually relocked without moving the pointer in the manner just set forth) for automatically -resetting the brake. This manual resetting, as above pointed out, is accomplished by means of the finger-piece 39 being pushed baclr by the operator, causing the beveled portion on the extension 35 to be engaged by the catch 31. This obviates the necessity of again locating the pointer over the record at the place where it is desired to stop the operation.

From the foregoing description, it will be observed that I have devised an exceedingly simple arrangement whereby positive stopping of a phonograph record is assured, whereby records requiring a stronger braking action to insure positive stopping thereof will also be attained., and whereby manual resetting of the stop mechanism may be accomplished.

lVhile I have shown my invention in the embodiment illustrated, it is to be understood that many changes may be made in the same without departing from the spirit thereof or its scope as set forth in the claims.
