 THB i p20 EMF ——•— -— — “It’s fixed!” The red-headed office boy popped into Mr. Gilmore’s private office and suggested that he push the button. He did so and the buzzer sounded. “Red” had saved the day, and that same afternoon he was Mr. Gilmore’s guest at the ball game. “That was a fine ‘stall’ you made yesterday. What do you know about electricity,” “Jimmie” the multigraph boy sarcastically remarked the next morning. “Red” answered with pride, “Why, I’ve done a lot of electrical wiring. I’ve wired a bell in our home, I’ve fixed up the buzzers for the people who live upstairs, and I’ve fixed mv mother’s electric flat-iron. I know a lot about electricity. Now this job was different. “You see. Mr. Gilmore has two buzzers and I knew they must be wired the same way as the bells up at our house.” In a jiffy “Red” took out his pencil and roughly sketched the following diagram on a piece of paper: “Now the buzzers were connected up like this. All there is to know is that there is a complete circuit from the push-button to the buzzer and then to the battery and then back to the push-button, like this:” SHfS ) t • “That’s how 1 wired the bells at home,” “Red” continued, pointing to the diagram. “You see, by pressing the upper push-button it rings the bell upstairs and the lower one rings our bell. You see, Jimfinic, this is the way these offices are laid out:” w M Page Three Hundred Thirty-three

C. O. Lindemann Edwin Kiefer THE TROUBLE SHOOTER “1 can fix it,” said “Red” the office boy, confidently, as he faced the exasperated office manager of the American Malted Wheat Company. Mr. Gilmore, the office manager, had arrived at his office determined to do a big day’s work and had pressed the push-button to summon his stenog- rapher. She had not come in, even after he had pressed the button several times. Then he had rushed angrily into the outer offices. The stenographers agreed that they had not heard the buzzer sound. “Well, then, it must be out of order. Send for an electrician,” said Mr. Gilmore to “Red.” It was then that “Red” had made his suggestion that he. himself, could fix it. “What do you know about electricity.” asked Mr. Gilmore. “Why, I wired up a bell in our house and one for the people upstairs.” “All right,” said Mr. Gilmore, “see what you can do.” Page Three Hundred Thirly-two

The two circuits, then, look like this:” CL E Rsr Fc srr-jBtfrroAf J30ZZEX N oaree Office un SECOND PVSH-eUTTON jBVZZER 1 STENOqEARNERS Room “Now, the first thing I did was to find out if the push-buttons were all right and the way I did that was to take a small wire and “cut-out” the push- buttons by connecting the wire to each side .of the push-buttons to furnish a path for the electricity to go around the push-buttons like this:” □ cur oar mres mi n “Then if the push-buttons are out of order, the buzzers will ring. Well, the buzzers didn’t ring, so I tested out the dry cells of the battery separately, leaving the push-buttons “shorted,” and I found the buzzers rang with two of the cells; one was “dead.” So I connected the two “live” cells together again (in scries) as I did at home and the buzzers rang. I then: removed the “jumper” across the push-buttons and asked Mr. Gilmore to try the buzzers. Well, Jimmie, you should have seen the look Mr. Gilmore gave me when they worked. He didn’t think 1 could lix the buzzers, but 1 showed him.” Page Three Hundred Thirty-four
