The Edison phonograph monthly (Dec 1914-Dec 1915)

8 EDISON PHONOGRAPH MONTHLY, JUNE, 1915 A FEW DON'TS WHICH APPLY TO EDISON DIAMOND DISC PHONOGRAPHS—MODEL B DON'T take out the Main Spring when a machine does not regulate, until you are sure that the trouble is with the Spring. DON'T take the Roller out of the Governor Shaft. If the roller binds on the side of the slot loosen the Governor Spring Screws and set the Sleeve so that the Roller is free, and tighten each screw a little at a time. DON'T forget that lubrication is a very important thing. See that the Governor is not gummed up. Clean well and oil with special "Edison Diamond" oil. DON'T use any other oil — this is important — as we have done a lot of experimenting, and have determined the best oil and grease to use. DON'T let the Turn Table Spindle Worm or Governor Worm run dry — oil with special "Edison Diamond" grease. Do not use light oil on these parts, or bad regulation and "noise" will result. DON'T fail to turn the Speed Indicator to "Stop" when removing the Turn Table. When the Spring is unwound see that the bronze Gear is free and has about one sixteenth of an inch side play. DON'T over-wind the Spring. This will strain all parts. Wind slowly and do not force the Crank when resistance is felt. DON'T allow the machine to get gummed up with dust. Remember, that a phonograph perfect enough to play our records as perfectly as our standard requires, is a fine piece of mechanism, and comparable to a watch. Notice the Friction Shoes that bear against the Governor Disc. See that they do not tip up. This will cause bad regulation. See that the Horn Feed Shaft is free. See that the Governor Pivot Bearings are not too tight, or bent, or all gummed up with old oil. Dry graphite — Dixon's No. 2 — is used on the Main Springs. If it is necessary to lubricate the Main Spring, remove the Plug Screw in the Barrel and wind the Spring up full. Then blow in a little graphite with an insect powder blower. Let the Spring unwind a few times and then repeat. Use just as little graphite as possible, and try to get it between the leaves of the Spring. Use "Edison Diamond" grease on the winding Gears. CAUSES OF BAD REGULATION Governor Frictions become tipped. Governor Sleeve gummed up, or dirty. Governor Shaft is not smooth. Governor Sleeve rubbing on the Roller Lack of oil on the Governor Pivots, Governor Sleeve, etc. Lack of grease on the Worm. Governor Pivots are too tight, or bent. Lack of oil on the Spindle bearings. Lack of grease on the Spindle Worm. Horn Feed Shaft is not free. Barrel Gear not free due to lack of oil, or Barrel Lining Disc is too tight on the sleeve. CAUSE OF NOISE Lack of lubrication. Improper adjustment of the Governor Worm Wheel. This can be adjusted by raising or lowering the Turn Table Spindle by means of the Adjusting Screw at the bottom, after the Set Screw has been loosened. Caution — be sure that the Motor is not wound when loosening the Set Screws. Governor out of balance — due to Springs not being bent alike. xAlso causes a "drunken" Governor. The most probable cause of "noise" is lubrication. MR. EDISON AGAIN HONORED ON May 7th the Civic Forum presented to Mr. Edison, "inventor and benefactor" a gold medal as a national testimonial. President Butler of Columbia University who presented the medal said: "This gold medal is not awarded for any particular achievement, but for distinguished services and great scientific achievements and in recognition of a great career, which has a place among the very highest in the roll of human history." Not all the friends and admirers of the inventor and scientist who went to the hall to pay him honor were able to get inside. All the seats from gallery to stage were occupied when Mr. and Mrs. Edison walked with the speakers to the front of the platform. The great audience of men and women stood when Mr. Edison and the others on the stage arose as the presentation was made. Among those who were present were: Henry Ford, President Ira Hollis of the Worcester Polytechnic Institute, E. W. Rice, President of the General Electric Company; Theodore N. Vail, President of the American Telegraph and Telephone Company; Guy E. Tripp, President of the Westinghouse Electric Company; Nicholas F. Brady, President of the Edison Electric Company; Union N. Bethel,, President of the New York Telephone Company; John Borroughs, Rear Admiral Robert E. Peary, Professor Arthur E. Kennelly of Harvard; Newcomb Carlton, President of the Western Union Telegraph Company; Gano Dunn, President of the J. G. White Engineering Company; J. G. White, President of the J. G. White Company, and Frank G. Sprague. President Wilson sent this message to Mr. Edison: "The White House, "Washington, D. C, May 6, 1915. "Please present my sincere and most cordial greetings to Mr. Edison this evening, and say how happy I would be if it were possible for me to be present to express my great admiration of his distinguished services and achievements. "Woodrow Wilson."
