This invention relates to the reproducing apparatus of talking machines and comprises a mod fication of the invention illustrated and descril.eJ in my pending application Serial No. 670,146, filed January 9, 1912. The present apparatus is designed especially to co-operate with records having grooves of uneven depth, the sound waves being recorded in the bottom of said grooves instead of in the sides of said grooves. The best form of apparatus embodying the present invention, together with certain modifications thereof, are shown in the accompanying sheet of drawings in which, Fig. 1 is a vertical central section of a soundbox adapted for use on cylindric The drawing shows a vertical central section of the preferred form of apparatus embodying the invention. -iZ al sound records.

Claussen, New York, assignor by mesne assignments to the Masterphone Corporation, New York. Patent Xo. 1,084,572. This invention relates to improvements on the particular form of attachment to talking machines illustrated and described in application Serial No. 670,146, filed January 9, 1912, in which is shown a thin sound amplifying disc rigidly mounted on the stylus of the reproducer of a talking machine. In the one particular form of the invention selected for illustration in said prior application the reproducing needle is clamped into the socket on the end of the stylus arm in the usual way, and the disc is held on the needle by being bored to form an opening of an internal diameter equal to or slightly less than the external diameter of the needle. This requires the needle to be forced through the disc before using, and, as it is not safe to use a needle on more than one record, it is necessary to pull the needle out of the disc every time a new record is put on, and stick a new needle through the disc before fastening the needle to the stylus arm for the next operation of the machine. While this can easily be done with a small pair of tweezers, the entire operation can be avoided by the use of the present invention, which comprises means for permanently attaching the disc to the stylus arm, and means for mounting the needle in this attaching means by any simple device such as a set screw. Consequently when a needle is worn it can be loosened from the disc, removed and a new one fastened to the disc without unfastening the disc from the reproducer. JO Talking Machine. — Matthew B. Claussen, New York, assignor by mesne assignments to the Masterphone Corporation, New York. Patent No. 1.084,573. This invention relates to talking or sound reproducing machines in which a stylus travels in a groove in a tablet or cylinder having variations of surface corresponding to sound waves. It is well known that in apparatus of this kind heretofore in use the loudness of reproduction may be increased by increasing the stiffness of the reproducing stylus, as by making said stylus of greater cross-section, tut this results in a disadvantage in that the reproduction is then less clear and faithful. On the other hand it is recognized that the clearness, delicacy and faithfulness of the repro duction may be enhanced by making the reproducing stylus light, as by reducing its cross-section, but this reduces the volume of sound. The inventor has discovered an improvement which may be applied to any of the standard forms of talking machine by which both the volume and clearness, or faithfulness, of the sound reproduction, arc markedly increased and improved. Briefly stated, this invention in its simplest form comprises the rigid attachment of a disc of convenient form to the standard form of reproducing stylus or needle. Fig. 1 is a side elevation of a portion of a talking machine showing the reproducer with invention attached. Fig. 2 is a plan view of the simplest form of disc attachment constituting the novel element of the invention. Fig. 3 is a similar view of a modification. Fig. 4 is a vertical central section on line 4 — 4 of Fig. 3 showing also the reproducer stylus or needle in position. Fig. 5 is a similar view with a different kind of stylus, and Fig. 6 is a similar view of a modification. Soundbox Arm for Talking Machines. — William W. Zackey, Philadelphia, Pa., assignor of fortynine one-hundredths to Chas. B. Hewitt, Burlington, N. J. Patent No. 1,083,045. This invention relates to the sound amplifying devices and has for an object to provide an amplifying arm and horn which are capable of transmiting and reproducing the sound with a minimum of variation from the original. It has for a further object to provide a novel means of eliminating the scratching and scraping noises which are produced by movements of the sound arm caused by vibrations of the sound record or irregularities in its surface. To this end a construction has been devised wherein the amplifying arm is maintained substantially in equilib rium, or floating condition, above the record but is <so adjusted and arranged as to permit an extremely sensitive action of the needle with respect to the record. Fig. 1 represents a side elevation of a sound reproducing device, embodying the invention, the same being shown partly in section. Fig. 2 represents an enlarged section of a portion of the device. Fig. 3 represents a section of line x—x, of Fig. 2. Fig. 4 represents a perspective of the supporting device for the sound arm. Fig. 5 represents a sectin of a portion of the same. Fig. 6 represents a section of a portion of the sound arm showing its connection to the soundbox. Fig. 7 represents a section of a modified form of the device. Soundbox.— Peter J. Mukautz, Chicago, 111. Patent No. 1,085,354. This invention relates to improvements in soundboxes for use in connection with sound recording or reproducing machines. The principal object of the invention is to provide a soundbox, which will so actuate the needle or stylus as it travels over the surface of the record, that clean-cut, smooth grooves will be traced therein; and in reproducing said record, the tones obtained will be intensified, clear and free from harsh or grating sounds. This is accomplished by confining air or a liquid between a pair of oppositely arranged cupped pistons of different diameters. Another object of this invention is to provide means for regulating the air or liquid pressure between the pistons, in order to get the best results from the soundbox either in making a record or reproducing the same. In the drawings, Fig. 1 is a sectional elevation of a soundbox constructed in accordance with the invention, for use in connection with a laterally undulating record groove machine. Fig. 2 is a similar view showing a soundbox for an up-and-down record groove machine, and Fig. 3 illustrates a modification of Fig. 1. BUYING AND SELLING POINTERS. Buy with one end in view, to sell. But remember, to sell means more than one sale. Therefore keep an eye open for quality, as well as price. Buy as near home as possible. You will gain in time of delivery and in price as well. If you are to sell, it will be necessary to buy. But remember that the selling depends largely on the buying. Buy with both eyes wide open. Then when you sell you won't fear to meet the steady gaze of your customer. The man who buys goods without taking selling into consideration reminds one of Br'er Rabbit and his experience with Tar Baby. Don't treat your jobber as if you distrusted him. Remember he is probably as anxious to hold your trade as you are to keep one of your customers. It you have a call for something you haven't got, and it's in your line, get it. But don't buy a gross unless you have more than one call for the article. The merchant who buys, without first studying his local market, is like a traveler without a map; he is likely to end his journey at the wrong destination. Buy early so that you can display the goods just before the season opens, thus securing the first orders, and also the reputation of being the leader in your lines. Buy with due regard for the taste of your patrons. Cater to the trade of the "upper ten," but don't forget that the "lower" ten thousand are the people who spend the greater volume of money annually. No honest purpose is ever wasted and no honest desire ever remains unanswered. Many a man's best friends are those who know him least.
