THE TALKING MACHINE WORLD. 47 IBS''* IE, '3" smoothly, regularly and evenly, thereby preparing a smooth, even surface for receiving a new impression. A further object is to provide such a device which at all times presents the cutting edge to the record at the same angle, thus causing a true and even cut. A further object is to provide such a device which holds the cutting instrument in exactly the same position during the trimming of a record. Figure 1 shows a side elevation of a trimmer for phonograph records embodying this invention. Fig. 2 shows a top or plan view of said trimmer. Fig. 3 shows a central, sectional view through the trimmer and parts of a phonograph showing the trimmer installed in position for use. This improved trimmer for phonograph records is designed especially for use with phonographs using cylindrical records and is also designed to be secured to the ordinary arm or bracket in which the reproducer is held. Record-Changing Mechanism for Sound Reproducing Machines. Julius Wellner, Philadelphia, Pa. Patent No. 1,023,573. This invention relates to sound reproducing machines of the class in which are employed a series of records discs, a magazine to support the series, a ;JJ" rotatable table to support and rotate a record during the reproduction thereof and mechanism to transfer record discs from the magazine to the table, and from the table to the maga-lJ zine. The object of the present invention is to provide a novel, simple and efficient magazine and transfer mechanism for the record discs, whereby the record discs may be supported in vertical posijrsye. tions, or substan j tially so, in the series, and whereby a selected record may be first moved edge first from the series to a position away from the same and adjacent the rotatable table and then moved face first from said position to a horizontal position upon the table to b e reproduced ; and whereby the record, alter being reproduced, m a y be first moved face first from the table to a position adjacent the magazine, and then returned edge first to the magazine. This invention in its broader aspect contemplates a record disc transfer mechan ism employing parts which may be operated to move a record disc face first down upon the rotatable table in transferring the record disc from the magazine to the table irrespective of the angular relation of the record disc to the table when the record disc is in the magazine. In the accompanying drawings, illustrating this invention, Figure 1 is a plan view of a soundreproducing machine, embodying the invention. Fig. 2 is a vertical section on line 2 — 2 of Fig. 1. Fig. 3 is a vertical section on line 3 — 3 of Fig. 2. Horn for Talking Machines. Thomas H. Towell, Cleveland, O., assignor to the U-S Phonograph Co., same place. Patent No. 1,033,215. The present invention, relating as indicated to horns for talking machines, has as its object the provision of a horn suitable for use on such machines, whether of the disc or cylinder type, and one that will be readily adjustable to the various requirements encountered in operating 'either such type of machine. The subject matter of the present case has been divided out of applicant's co-pending application Serial No. 574,467, filed July 29, 1910, and relates more especially to the amplifier as distinguished from such amplifier in combination with the talking machine mechanism. In said annexed drawing, Figure 1 is a side elevation of one typical form of cylinder talking machine, with a horn shown in connection therewith embodying the present improvement; Fig. 2 is a horizontal sectional detail of such horn, 2-2, Fig. 1; Fig. 3 of a detail of the O; r taken on the plane is a vertical section jointed elbow connecting on the plane 2 — 2, Fig. 1 ; Fig. 3 is a vertical section of a detail of the jointed elbow connecting the tone arm with the amplifier proper; and Fig. 4 is similarly a vertical section of the forward end of said tone arm, the pitch of the coiled interlocking strip composing such tone arm being exaggerated in order to render the construction of the latter clear. Means for Automatically Arresting Talking Machines. Arthur E. Spencer, San Francisco, and Frank C. Thomas, Mill Valley, Cal. Patent No. 13,453 (reissued). This invention relates to means for arresting the rotation of a talking machine automatically upon the stoppage of the sounds reproduced by the talking machine. The object of the invention is to provide a device for accomplishing this and which will not necessitate any change in the form or construction of the record itself or in the mode of using the talking machine. Figure 1 is a broken plan view of a talking machine equipped with the invention ; Fig. 2 is a broken side view thereof; Fig. 3 is a detail crosssection on the line 3—3 of Fig. 1 ; Fig. 4 is a detail vertical section on the line a — a of Fig. 1, showing the positions of the parts when the tone tube is elevated ; Fig. 5 is a similar view showing the positions of the parts when the ~ . _. _ , tone tube is low igz s& ered to its operative position; Fig. 6 is a similar view showing the positions of the parts when the tone tube is also in the lower position but the pin has arrived at the end of the record. Method of Making Sound Records. James W. j i HS3 3 E Owen, Philadelphia, Pa., assignor to the Victor Talking Machine Co., Camden, N. J. Patent No. 1,033,909. The main object of this invention is to provide an improved method whereby a matrix or a record of sound may be produced, so marked for ■identification that duplicates thereof cannot be formed or "dubbed" from it without incorporating into such duplicates the identification marks of the original, this application being a division of inventor's prior application, Serial No. 430,657, filed May 4, 1908, upon which issued United States Letters Patent No. 964,686, dated July 19, 1910. This method is preferably utilized to form an ■identification mark or marks within the recorded surface of the record, the term "recorded surface" being used to define the whole or any part of the surface of the undulatory sound groove or ridge of a record or of the surface between the turns of such groove or ridge. Preference is given to an identification mark or marks such as a word or words, or characters of any description, that will indicate the origin of the record or that will give any other information desired. In the drawings forming a part of this application, in which the same reference characters are used to designate like parts throughout the various views, Figures jr,yj 1 to 3 illustrate r — r^'^-^-^A-^ one method of su^e f >>//^2 forming identification marks in a sound record matrix ; Figs. 4, 5 and 6 show a modified manner of carrying out the said method ; Figs. 7, 8 and 9 show a still further modified process of marking a sound record tablet having identification marks formed in the recorded surface thereof. Needle Holder for Talking Machines. Julius Jetter, Camden, N. J. Patent No. 1,034,387. This invention relates to machines of the character known as "talking machines," more particularly those employing disc records; and the object of the invention is to provide a multiple needle holder which may be mounted upon a suitable supporting arm whereby attachment may be made to the recording or reproducing element of the talking machine. The needles ordinarily employed when reproducing talking machine records wear out very rapidly, and it is the present practice to supply a fresh needle for every record. Attempts have been made to produce a needle capable of use for a number of records, but they have not proved very satisfactory, and in general the high cost of production has usually prevented their adoption. The multiple structure forming the subject of this invention is rotatable and operates in such a way as to permit the needles carried thereby to be used consecu F/g.Z. tively and afterward removed at one time and others set in their places, and it may be made of any suitable material, preferably metal. Figure 1 is an elevation of a multiple needle holder embodying the invention; Fig. 2 is a side elevation of the same, partly in section, on the line a — a, and Figs. 3, 4, 5, 6. 7, 8, 9 and 10 are views illustrating forms of needles which may be mounted for use in the structure embodying the invention shown in Figs. 1 and. 3.
