The Edison phonograph monthly (Dec 1914-Dec 1915)

EDISON PHONOGRAPH MONTHLY, APRIL, 1915 11 One of a Hundred Microscopes in Use Before the Fire. The Results of the Fire on the Microscope Nearby three smaller bottles or vials stood in a group. These were smaller than the bottle just mentioned, being only one inch high and one inch in diameter. All three bottles were fused together but their shape remains quite perfect. Every bottle in the group contained jewels, and every one of these are preserved. All three covers of these little bottles were of tin screwed on to the glass. They were not sealed by the heat. Another evidence of the intense heat is shown in the collapse of a small glass bottle not over 2^ inches high, and V/i inches diameter, shown in the illustration herewith. The cork of the bottle was entirely consumed, early in the process, then the neck of the bottle became plastic and hermetically sealed itself after the cork was consumed. This bottle contains over 24,000 diamonds, but hermetically sealed. DON'T ATTEMPT TO REPAIR EDISON DIAMOND REPRODUCERS The Edison Diamond Reproducer represents three years of continuous research by Mr. Edison himself, during which he built, tested and discarded 2,300 different types of reproducers. The respective types that he finally adopted for the Edison Disc and Cylinder instruments prove by their splendid tone quality that Mr. Edison's time was well spent. These reproducers must be assembled with the greatest skill and tested more rigidly than is possible for anyone not having our equipment. If a dealer knew how many brand new reproducers are rejected by the inspectors before they leave the factory he would realize the absurdity of expecting an outside man to properly repair and test one with his limited facilities. The repair of Diamond Reproducers by any dealer or jobber is unauthorized. {Please note the restriction notice attached to each reproducer box.) It is of the utmost importance that no jobber or dealer, however skillful he or his repair man may be, shall attempt to repair Diamond Reproducers or have them repaired elsewhere than at the Edison factory. To insure against any attempted repairs to Diamond Reproducers outside of our factory, and to entirely remove all reason or excuse on the part of dealers for attempting to repair Diamond Reproducers, we hereby announce that until further notice, dealers may return to their jobbers, carriage charges prepaid, any Edison Diamond Reproducer requiring repair, and another reproducer will be supplied in its place without charge, provided the occasion for the repair of the reproducer is not its improper or careless use, and also, provided, that no parts are missing. Every reproducer returned should be sent back in the container in which it was received. Remember that the carriage charges must be prepaid, and if the dealer desires his jobber to send him the new reproducer by parcel post, he must send the necessary postage. Otherwise it will be sent express charges collect. No dealer should demur at paying the carriage both ways, for such charges will be much less than the cost of making the repairs. "It is no uncommon thing for the salesmen on our force to take anywhere from ten to fifteen 'minutes only for lunch, for fear if they take the allotted hour they will lose a sale." — From a New York dealer's letter. WHY AN EDISON DISC RECORD WILL LAST LONGER THAN ANY OTHER DISC? 1st. Because it is so remarkably hard and tough. 2nd. Because the sound wave grooves are up and down — not side ways. 3rd. Because the Diamond Reproducer point fits the sound wave grooves and runs along the grooves with absolute smoothness. 4th. Because the sound wave groove is not used to move the reproducer point across the record. It is propelled by its own mechanism.
