Application filed June 27, 1916. Serial No. 106,231?" ToV all whom t may concern:

Be it known that weCHRIs'rIAN S. GER- LACH and CHARLES F. HERMAN, citizens of the United States, residing at Brandon, in the county of Fond du Lac and State of Wisconsin, have invented new and useful Improvements in Graphophone-Stops, of which the following is a specification.

This invention comprehends the provision of means for tripping the automatic stop mechanism of a talking machine immediately after the music ceases, irrespective of the dimensions of the record or lengthof the particular selection.

The nature and advantages of the inven tion will be better understood as the following description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this specification like numerals of reference indicate similar parts in the several views and wherein Figure 1 is a fragmentary top plan view of a talking machine showing our invention applied thereto.

Fig. 2 is an enlarged detail sectional view of the mechanism forming the subject matter of the invention.

Fig. 3 is a view showing the trip mechanism of the machine and the mechanism forming the subject matter of the invention partly in section.

Fig. l is a sectional view taken on line 4-4 of Fig. 2 looking in the direction of the arrow.

The mechanism forming the subject matter of our invention is primarily intended for use in connection with a machine of the character illustrated, although it is susceptible for use with other types of talking machines, and its general application is contemplated by the claim.

The mechanism preferably embodies a support 10 adapted to be secured upon the horn part A of the automatic stop mechanism of the machine in any suitable manner, the support 10 constituting a bearing for the shaft 11 which latter is mounted for rotation.

The upper extremity of the shaft 11 is provided with a knob 12 for rotating the shaft in either one or the other direction, while carried upon the opposite end of the shaft is a pinion 13 meshing with a rack bar la to manipulate the latter simultaneously 14 is an actuating member 15 the purpose of 'which `will be hereinafter more fully described.

Mounted upon the support 110 is a dial 16 graduated alongits outer edge and- .having suitable' indicia-7 such as numbers with which the indicator hand 1'7 cooperates to determine the degree of adjustment essential for the different records or selections' to be played. The indicator hand 17 is carried by a stub shaft 18 which is journaled upon the support 10, and provided with a gear wheel 19 which meshes with the gear 20, which latter in turn cooperates with the gear 21 on the shaft 11 to cause the indicator hand 17 to move in the same direction as the knob 12 when the latter is operated.

In practice, a record is placed upon the machine and the latter started, and at the end of the selection, or in other words when the music ceases, the knob 12 is rotated in the proper direction to move the rack bar 14 toward the trip B of the automatic stop mechanism of the machine. When the actuating member 15 of the rack bar engages the trip B, the automatic stop mechanism of the machine operates to throw the stop proper into operative position. When the trip B is actuated the operator ceases to rotate the shaft 11, and takes note of the particular number on the dial to which the indicator hand points. The record is then removed from the machine and marked with this number for future use. That is to say that when this particular selection is again used, it is only necessary prior to the starting of the machine to adjust the indicator finger 17 to the number in question, which moves the rack bar 15 to theproper position with respect to the trip B of the automatic stop mechanism, to stop the machine immediately at the finish of the selection. In order to determine the proper number of each record, the operator can if desired, move the needle to a point approximately one-fourth of an inch away from the center of the record, be fore starting the machine, and then rotate the shaft 11 to move the rack bar into en-.

gagement with the trip B. The needle can then be placed at the peripheral edge of the record and the machine started. When the record has been removed the same must be kformed to engage notches 22 ripheral Vedge of the dial 1,6 so

marked WithV the number indicated on theV dial by the hand 17, which Will be the numberof this record forrfuture use. c

The indicator hand 17 is preferably along the peas to prevent slipping. backward of the rack 'barV 15 When the latter isbrought into engagement with the trip `B kof the automatic stopmechanism. ,While-We have shown and described What We consider the preferredembodiment of the invention, VWe desire tohave it underv stood that rWe do not limit ourselves to this particular construction and arrangement of parts, and that such changes may be resorted to When'desired as fall Within the scope of AWhat is claimed. Y Y Y What is claimed is:

The 'combination with a trip element of an automatic stop mechanism for a talking machine, of an actuating element therefor having a rack surface, a shaft mounted for rotation, a bearing for said shaft, a pinion carried by one end of the shaft and meshing With therrack surface of the actuating element to effect an adjustment of the latter With respect to the trip element, a dial provided with indicia, a plurality of stud shafts journaled in the bearing, a hand carried by one of said stud shafts and coperating with indicia on the dial to indicate the adjusted position of the actuating element, and gearing carried by the respective shafts and meshing with each other to cause the hand to move in the same direction as the first mentioned shafts.

In testimony whereof We affix our signatures.
