182 THE TALKING MACHINE WORLD April IS, 1921 Still another object is to provide a device of this character in the nature of an attachment which may be readily applied to the knuckle at the connection of the gooseneck with the tone arm. The invention is illustrated in the accompanying drawings, wherein: Figure 1 is a perspective view of a tone arm and gooseneck, showing the attachment applied thereto and showing the sound box in dotted lines; Fig. 2 is a fragmentary side elevation of the tone arm and gooseneck of the device; Fig. 3 is a perspective view of the clip; Fig. 4 is a top plan view of the blank from which the clip is made. Tone Arm Base. Attilio Regulus Spicacci, West Hoboken, N. J. Patent No. 1,363,061. This invention relates to talking machines, and an object of the invention is to provide a base and tone arm constructed to permit a free turning movement, while at the same time presenting a mechanical construction which will not readily get out of order and which will wear for a long time. Figure 1 is a longitudinal vertical section through part of a talking machine, the same disclosing an embodiment of the invention; Fig. 2 is a fragmentary sectional view through Fig. 1 on line 2 — 2; Fig. 3 is a front view of the base shown in Fig. 1, the same illustrating certain parts of the invention. Record-repeating Device. William H. Fink, Diagonal, la. Patent No. 1,362,091. The object of this invention is to provide a device of simple, durable and inexpensive construction which will efficiently move the tone arm of a phonograph after a record has been played to its starting position for repeating the playing of the record without interfering with the ordinary use of the phonograph and without injury to the record. A further object is to provide such a device including a disc or wheel having a flat portion in its periphery, and balanced by means of weights or the like, causing the wheel to stand in position with the flat portion away from the disc, which device has coacting parts, including means for holding the wheel or disc in position with the flat portion above the record, and a device adapted to be engaged by the moving tone arm when the record has been played for releasing said holding means, and which device also has means adapted when the holding means is released and the wheel rotates to its normal position to be actuated by the rotation of the wheel in contact with the disc for lifting the tone arm and moving it to starting position, and lowering it to plaj'ing position.

Phonograph. Everett H. Bickley, Philadelphia, Pa. Patent No. 1,364,689. The nature of this invention consists of a m.eans for cutting into a sound record an additional groove having a different and steeper pitch than the groove used to record the sound waves, said groove being a continuation of the sound groove, the object being to provide a guiding groove which will throw the sound arm of any phonograph to a predetermined center or inner circle of the record quickly, after the record has been played. The steeper pitch groove is cut by this mechanism in the master record disc, from which duplicates are afterward made, at the termination of the music, by operating a lever conveniently provided, and the sound arm is raised ofi the disc at the predetermined radius, automatically. The mechanism is stopped automatically also when the cutting is complete, said means being incorporated in and a part of the cutting mechanism to cut the sound record groove in the master record, from which duplicate records are made. A very simple attachment is now provided on many phonographs which will trip the "stop" when the tone arm reaches the last spiral of the record, but it must be set for each record. By the incorporation of this additional groove of steeper pitch into the record, and with the simple attachment mentioned above, the phonograph becomes selfstopping without setting or adjusting, for all records. The shape and character of this groove has been made the subject of an additional patent application filed February 23, 1920, Serial No. 361,243. It is a very difficult mechanical problem to cut a spiral of varying pitch at the end of a spiral of uniform pitch and imdetermined length, and especially a spiral of certain fundamental character such as one that will give a uniform side pressure on the needle point at all times. Furthermore, there must be no angularity as the needle changes from one spiral to the other, and, to accomplish the best results, the spiral should end at a predetermined distance from the center, \>y the bottom of the groove coming up to the level of the surface. This prevents damage to the fragile needles that are now used to play a large number of records without change. It'will be noted that a master record made on this device is cut completely at the one setting, with one cutting. The cutter arm is guided correctly for the fine spiral and when the music ceases by the operation of a lever a ciutch is thrown in whereby the pitch is smoothly and gradually increased and the groove ended at tlie proper place, in the correct manner, without further attention or operations. Tn the accompanying drawings Figure 1 is a side elevation showing the phonograph turntable, the driving mechanism and speed controller, tone arm, sound box, the record disc and top of the phonograph. Incorporated with these customary parts are the novel mechanism for superimposing upon the movement of the tone arm an additional movement controlled by the njotion of the turntable and a specially designed cam to give a uniformly accelerated motion to the tone arm as it moves toward the center of the record. This view is sectiona^zed on the line A — A. Fig. 2 shows the same mechanism rotated 90 degrees so that the rear view may be obtained, sectionalized at B — B (Fig. 1). Fig. 3 is an enlarged sectional view of the tone arm elevating device. Fig. 4 is an enlarged plan view of the special cam and roller. Phonograph Needle. Frederick W. Peisch, Chicago. 111. Patent No. 1,370,763. This invention relates to improvements in phonograph needles and has for its object the provision of an improved construction of this character by means of which a needle is provided, capable of producing varying tones and also capable of prolonged use and ready renewal. Figure 1 is a perspective view of a phonograph needle embodying the invention; Fig. 2, an end view of the same, and Fig. 3, a longitudinal section of the .same. Disc Record. Herbert W. Meyer, Chicago, 111. Patent No. 1,372,822. This invention relates to improvements in disc records for phonographs. In the use of disc phonograph records, trouble is often experienced in locating the beginning of the recording groove. This is especially true where phonographs are located away from good light, as, for instance, in an apartment building, some distance from the onl}' window in the room. Man}' times the needle is placed on the record considerably within the outer groove, and thus part of the selection is eliminated. On the other hand, it frequently happens that the needle is placed on the very edge of the disc, and is caused to drop off the edge. An object of the invention is to eliminate the objections mentioned above by providing a locating or guide groove which can be readily seen and which is of such size that the needle can be readily placed therein. A further object of the invention is to provide a guide groove having an auxiliary groove leading therefrom to the record grooves, so that the needle, having been located in the guide groove, will find its way automatically to the record grooves.
