When the above-mentioned upper roller descends, due to a decrease in the thickness of the strick, the oblique rod and its fulcrum is moved slightly counter-clockwise, and less oil is liberated for the thin part of the strick. It will be understood that all makers of softening machines supply the automatic lubricating or batching apparatus when desired.
Jack went down the companion steps into a forepeak stuffy with the heat of the sun and a galley stove, a cramped place where they ate heartily despite faint odors of distillate and burned lubricating oil from the engine room and bilge water that smelled of fish. A troller's boat was rubbing against the Blanco's fenders when they came on deck again.
While this system of oiling is not unique, it was the first instance of its adaptation on so large and complete a scale, and illustrates the far-sightedness of his plans. In connection with the adoption of this lubricating system there occurred another instance of his knowledge of materials and intuitive insight into the nature of things.
The petrol consumption of the type is very low, being only 0.48 lbs. per horse-power per hour, and equal economy is claimed as regards lubricating oil, a consumption of as little as 0.04 lbs. per horse-power per hour being claimed. Certain American radial engines were made previous to 1914, the principal being the Albatross six-cylinder engines of 50 and 100 horse-powers.
Owing to the shortage of lubricating oil it is to be feared that this last mode of conveyance left to the Belgians will have to be stopped shortly. October 30th: A decree dated September 30th makes the measures for the requisition of metals still more severe.
The friction of iron rubbing upon brass has generally been taken at about one eleventh of the pressure under the same circumstances; but in machines in actual operation, where a film of some lubricating material is interposed between the rubbing surfaces, it is not more than one third of this amount or 1/33d of the weight.
The refined products have various uses. Probably the most important is the lubricating oil. This is necessary in the development of all kinds of power. At least one-half pint of lubricating oil is used for every ton of coal consumed for power.
But when a film of lubricating material was interposed, he found that the friction was the same whether the surfaces were wood on metal, wood on wood, metal on wood, or metal on metal; and the amount of the friction in such case depended chiefly on the nature of the unguent.
All engines, all street and steam railways, steamships, sewing-machines, clocks, watches, and automobiles, in fact all operating machinery requires its use; so that a large amount of oil must always be conserved for lubricating purposes. Coal oil, or kerosene, may be regarded as absolutely necessary for the lighting of houses or other establishments not connected with gas or electric supply.
And these three things are the three things for which we Christian people have received all our dew, and all our beauty, and all our strength that we may give other people light, that we may be the means of conveying to other people nourishment, that we may move gently in the world as lubricating, sweetening, soothing influences, and not irritating and provoking, and leading to strife and alienation.
