March 28th, 1900 Mr. W.L. Sanders, Vice President The Ingersoll-Sergeant Drill Co., Havenmeyer Building, New York City Dear Sir:-- Replying again to yours of the 7th inst relative to the Re-heater, we beg to state that Mr. Edison has returned, and in going over Mr. Dickerson's report, says that the re-heater was put to do more work at Jerome Park than he had intended, It should have been used only in connection with a couple of drills, then there would not have been the trouble in clinkering of the coal or the trouble with the ashes getting into the drills. He claims that the quantity and velocity of the air going through the fuel chamber, was entirely too great, and that he is surprised that the re-heater did nearly as well as Mr. Dickerson reports. He says that under the conditions the re-heater was used, it was practically turning it into a small blast furnace and making it do several times more work than was intended. We expect to start our works at Edison about the 15th of next month, and will fix up the re-heater, sending it to Edison, putting it on our lines there and give it a thorough test. Relative to the shutting off the air when the re-heater is being filled with fuel, Mr. Edison states it is always the intention to make a by pass round the re-heater, so that the air, while the re-heater was being filled, could go direct to the drills not heated. He gave Mr. Dickerson directions to do this, and in the first instance it was done; in the second instance, for some reason unknown to us, Mr. Dickerson put it directly in the line without a bypass, causing the trouble to which Mr. Wise refers. Mr. Edison has returned from the south very much benefitted by his vacation and very anxious to push the re-heater business to a successful conclusion at the earliest possible moment. We have been as yet unable to get the steal flexible tubing. Can you give us any help in the matter? Yours very truly, W.S. Mallory
