That odd gentleman, with never a thought of blessing anything now, unless he did it silently, was watching the lubricating system. This was a vital part of the craft, for if anything went wrong with it, and the bearings overheated, the race would have to be abandoned.
By making them of good length 1 inch the wear is reduced to almost nothing if the lubricating can is used as often as it should be. Each bearing is shown with two standards. The doubling increases rigidity, and enables an oil cup to be fixed centrally.
"We've made some improvements since you were here last, sir," said Polton, who was delicately lubricating the steel guides. "We've fitted these steel runners instead of the blackleaded wooden ones that we used to have. And we've made two scales instead of one. Hallo! That's the downstairs bell. Shall I go sir?" "Perhaps you'd better," said Thorndyke. "It may not be Mr.
The lubricating oil pump is of the valveless two-plunger type, so geared that it runs at seven revolutions to 100 revolutions of the engine; by counting the pulsations the speed of the engine can be quickly calculated by multiplying the pulsations by 100 and dividing by seven.
These, and the facts appropriate to them, she meted out to her biographers from time to time, lubricating her amiable confidences with the assertion that both she and her husband felt that the people were entitled to be made familiar with the lives of their public representatives.
He must know when to begin shovelling coal, and when to stop; when to open the blower and when to shut it off; when to keep the furnace door closed, and when to open it; how to regulate the dampers; when and how to admit water to the boiler; when to pour oil into the lubricating cups of the cylinder valves and a dozen other places; when to ring the bell, and when and how to do a multitude of other things, every one of which is important.
The small leakage of water into the vessel which is thus occasioned, keeps the screw shaft in this situation always wet, and this is all the lubrication which this bearing requires or obtains. Q. What is the utmost pressure which may be employed without heating when oil is the lubricating material? A. That will depend upon the velocity.
Una spent much of her time in copying over and over a hundred times, two hundred times form-letters soliciting advertising, letters too personal in appearance to be multigraphed. She had lists of manufacturers of motor-car accessories, of makers of lubricating oils, of distributors of ball-bearings and speedometers and springs and carburetors and compositions for water-proofing automobile tops.
We were rather surprised to find that the coal and lubricating oil for the engine room were purchased by the manager himself, but not at all surprised to learn that he had never heard of such a quantity as a British Thermal unit and that he had absolutely no records to show the kind of coal most efficient under his boilers.
Grahame White, with one of the 100-horse-power "Greens" succeeded in winning the duration Michelin with a flight of over 300 miles, carrying a mechanic and pilot, 85 gallons of petrol, and 12 gallons of lubricating oil. Compulsory landings were made every 63 miles, and the engine was stopped.
