This invention relates to improvements in sound reproducing machines, and has particular reference to stop mechanism for au tomaticallyarresting rotation of the turntable and its superposed record, and at any predetermined point.
It is an object of this invention to provide a stop mechanism which can be operatively associated with various types of reproducing machines adapted to play diiferent makes of records.
Another object of the invention is the provision of a stop-mechanism which can readily be attached to existing types of machines.
A still further object within the contemplation of my invention is the provision of a stop-mechanism, certain in its operation and easily set by the operator, and adaptable to existing types of machines, whereby rotation of the'turirtable is automatically controlled by movement of thetone-arm, the latter preferably carrying instrumentalities which co-act with instrumentalities carried by the turntable actuating-mechanism, the controlling-mechanisin being settable at the will of the operator, first, to arrest the turntable and its superposed record at any predetermined point and, secondly, .to govern the operation of the turn-table for various types of machines without requiring modification of the controlling-mechanism. In other words. the structure constituting the inventive concept in such that it is adaptable to various types of sound-reproducing machines without modifying the construction in any regard, the structure including means for adjusting the parts to co-act according to the particular type of machine with which it isassociated.
A still further object of the invention is the provision of means whereby the structure, when once set to play a record, may operate again without requiring manual resetting of the parts.
With these and other more or less important objects in view, the invention resides in a structure which includes, preferably, a base Specification of Letters Patent.
or support for Patented Au 30, 1921. Application filed May 8, 1920. Serial No. 379,854.

Referring to these drawings, the numeral 1 designates the casing of a sound-reproduc ing machine, of construotlon,
which is provided table 2 for su aortln a 3, having grooves 23 and any appropriate type and with av turnphonograph record a tone-arm 4 carrying a reproducer or sound-box 5.
' Encircling the tone-arm 4 is a pointer supporting member or ring 5, formed with an upstanding portion or collar 6, threaded as at 6 and adapted to be rigidly secured to the tone-arm, asby screws 6 Carried by the member .5 sum or arm 7.
a pointer-sustaining exten- In this instance, the tone arm is mounted includes a vertica securable to thecasscrews A and also 1 portlon A adaptedto encompass the tone-arm, as shown. Preferably and as shown, the bearing-member includes an internal cross-web A Upstanding from the cross-web is a pivot-post A which extends through a cross-piece 4 within the tone-arm, the post extending into a journalboss 4: in the tonearm 41. The post A provides an additional means of maintaining the tonearm for effective operation and against undesirable vibration as the tone-arm travels over the record 3. It will be understood that the tone-arm is adapted to have free movement in the bearing-member A.
The bearing-member A constitutes a support for certain of the components, hereinafter described, forming the stop-mechanism which characterizes my invention.
Preferably and as shown, the collar 6 of the ring 5 has associated therewith a tripcarrying member or ring 8 provided with an outstanding plate or projection 9 on which is formed an ear l0. Pivotally secured to the ear is one member 11 of a toggle, the other member 11 of which turns on a pivot-washer 12 upstanding from the arm 7. Integral with or rigidly secured to the member 11 of the toggle is a limit-setting member or pointer 13 which is settable by the operator at different positions on the record to regulate the mechanism for stopping the turn-table 2 at any desired or required point.
Depending from the pointer 13 is a boss 14 forming a connection between the togglemember 11 and the pointer 13. The pointer and toggle-member 11 pivot on a screw 16 threaded into the arm 7.
Depending from the plate 9, and near the inner portion thereof, is a bifurcated stud 17, in which is plvotally mounted a tripsustaining member 18, movement of which is controlled by spring 18 Upstanding from the member 18 is a trip 19, this extending through an aperture 9 in the plate 9. Normally, the spring 18 has a tendency to move the trip-sustaining member toward the underside of the plate 9, and means (presently to be described) are provided for varying the extent of movement of the member 18. It will be understood that the posi- -tion of the trip 19 is such as normally to be in the path of travel of tie tone-arm as the same moves across the record and in order that it may engage the trip and operate the parts, as will presently be described. The free end of the member 18 is provided with a eatch 18 for a purpose now to be described.
Pivot-ally mounted on the underside of the plate 9 is a brake-member designatedv generally by the reference-character 20, and of hammer-like form. This brake-member is provided with a hammer 21, adapted, when the trip is actuated, to engage with and arrest rotation of the turn-table. The hammer is, preferably and as shown, provided with a facing of rubber, felt, or other resilient material 22, which aids in arresting rotation of the turn-table. Disposed at an angle to the hammenmember is an extension 23 )provided with a beveled portion 23 for the purpose of engaging the catch 18 and holding it against movement until the tone-arm is brought into contact with the upstanding trip 19. A spring 24, secured (as by a screw 25) to the underside of plate 9,'bears against the brake-member and is adapted when the trip 19 is engaged by the traveling tone-arm and rocks on its pivot so that the portion 20 with its catch 18 is pressed out of engagement with the beveled portion 23 and permits the brake mechanism 20 to be forced by the spring 24:, against the rotating turntable and thereby stop the same.
Means are preferably provided for varying the extent of movement of the brakemember 20, and comprise a screw 26 threaded through the plate 9, adjacent the trip 19, and adapted to engage the brake. By raising or lowering this screw, the time of release of the hammer can be varied.
Preferably and as shown, means are provided for maintaining the movable ring 8 in proper operating position and comprise a ring-element 27 secured, as by screws 28 threaded therethrough and engaging the collar 6 of the supporting ring 5*.
To maintain the trip-carrying ring 8 in spaced-apart relation to the base of the ring 5 and to the holding ring 27, fiber washers 28 are inserted therebetween, as shown.
The structure, as above described, con stitutes a trigger-mechanism which, by reason of being secured to the casing 1 of the machine is relatively stationary during the traveling movement 'of the tone-arm. In
order to operate this trigger-mechanism directly by the tonearm, means are provided on the tone-arm that are engageable with the trigger-mechanism to operate the same when the tone-arm has reached a predetermined position; and I shall herein refer to the components carried by the tone-arm as the trigger-actuating mechanism; it being understood that this mechanism travels with the tone-arm in relation to the relatively stationary trigger mechanism. This mechanism includes a settable disk-member 29 secured, as by a screw 30, to a portion of the tone-arm attached to a boss or stud 31 secured to the tone-arm. The disk carries two tripping pins 32 and 33, disposed at different distances from the axis of the disk and adapted to be disposed in the path of movement of the trip 19. These pins 32 and 33 are differently spaced from the axis of. the disk 29, as shown, in order to adapt the structure for different types of records. As is well known, some typessuch as the Pathe, for instanceare more difficult to itsdisk 29, has reached that arrest in their movement; wherefore, in order to maintain the engagement of the trip 19 with one or another of these pins for a greater or lesser time, their arrangement with respect to the axis of the disk has been developed as shown. When the pin 32, for instance, is positioned so as to be engaged by the trip 19, it-by reason of the fact that it is disposed nearer the disks axis-will.
vary the actuating movement of the trip 19 to such an extent that a greater amount of leverage will be provided and, thus, permit the hammer to impinge with greater force against the turn-table.
For the purpose of limiting the turning movement of the disk, pins 34 and 35 are mounted on the back thereof, which are adapted, when the disk 29 is turned, to engage a downwardly projecting finger 36, mounted on the boss 31 and thus keep the disk 29 and the attached pins 32 and 33 in operating position.
As above pointed out, it has been found in practice that certain makes of records,
such as the Pathe (which are played with so-called sapphire points or balls) require a stronger braking action to insure success ful operation of the stop than do records employing steel needles or diamond points as the reproducing medium. Consequently, when playing records with sapphire points, the disk 29 is revolved so that 11; will bring pin 32 into register with the trip 19 so that greater leverage will be provided and, consequently, the hammer will be forced against the turn-table with more force and thus insure positive stopping of the turntable, as above pointed out.
Operation: After the record has been placed on the turn-table, the pointer is brought to the position on the record where it is desired to trip the brake. By moving the pointer in this manner, it will be observed that, through the connected lever arrangement 11, the plate 9, with the upstanding-pin 19, will be moved to the left. If the record is being played with a sapphire ball, the disk 29 on the tone-arm is revolved to bring pin 33-which is placed nearer the outer edge of the disk 29 than pin 32 and is so limited in'its movement by pin 34 on the reverse side of a disk 29 contacting therewithinto such a position that it will be engaged by the trip 19 sooner than. when pin 32 is turned for engagement with the trip and, thus, advance the instant of engagement of the brake-member with the turn-table to eifect its earlier operation which, in practice, has been found desirable when playing records with hilland-dale grooves. When the tone-arm, with travel where the predetermined pin 32 or 33 contacts with the upstanding port on 19, the pressure of the p1n against said uppoint in its standing portion will force the same to rock or yield sufiiciently to release the catch 20, permitting the hammer 21 to be forced, by means of the spring 21, against the turntable and, thus, bring the turn-table and its superposed record to a complete stop.
If it is desired to place a new record on the machine, the pointer 11 must be turned so that it will permit withdrawal of the record then on the turn-table. In so moving the pointer, the projection 9 is, through the toggle-lever arrangement, carried to the right, forcing the hammer 21 against the turn-table and, thus, causing it to automatically re-lock itself by pressing the extension 23 on the hammer and causing the beveled portion 23 to ride over the catch 13 Thus it will be seen that the stop is automatically reset. After the new record has been placed on the turn-table, the pointer is again brought to the proper position on the record. By moving the pointer to the right and over to about the center of the record, it will carry the plate 9, with its attached brake 20, out of engagement with the turntable and permit further rotation.
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, and whereby records requiring a stronger braking action to insure positive stopping there of will also be attained.
