The consideration for them seems unfailing; they are asked to do things if they please, and they are invariably and distinctly thanked for the smallest service. There are no doubt exceptions to the kindness which one sees, but I did not see the exceptions. The social machinery has so little play that but for the lubrication of these civilities the grind of class upon class might be intolerable.
WHEN THIS RESPONSIVE ENLARGEMENT and lubrication are fully realized, it is made plain why the haste and force so common to first and subsequent coition, is, as it has been justly called, nothing but "legalized rape."
Politeness is, after all, but the dictate of a kind heart, and supplies the oil necessary to make the social machinery run smoothly. In home life, which is the association during many hours each day of people of varying dispositions, views, and occupations, friction is inevitable; and there is especial need of lubrication to lessen the wear and tear and eliminate jarring.
In the meanwhile he was working away at his motor-boat, installing several improvements. One of these was a better pump, which circulated the water around the cylinders, and another was a new system of lubrication under forced feed. "This ought to give me a little more speed," reasoned Tom, who was not yet satisfied with his craft. "Guess I'll take it out for a spin."
When the engine is first put under steam, lubrication should be very liberal, to assure the parts "settling down" without undue wear. The Pump. The method of making it will be obvious from the diagrams, and space will therefore not be devoted to a detailed description.
This latter deserves special mention, not only because of its arrangement for thorough lubrication, but also on account of the resultant economy affecting the cost of manufacture. Edison has strong convictions on the liberal use of lubricants, but argued that in the ordinary oiling of machinery there is great waste, while much dirt is conveyed into the bearings.
But this constancy cannot be obtained. The coefficient of friction varies with the condition of lubrication of the surface of the pulley, which alters during the running and with every change in the velocity and temperature of the rubbing surfaces.
The power is applied through turbine screws, half of which are capable of propelling the flat deck in its inclined position at sufficient speed to prevent its falling. The moving parts have ball bearings and friction rollers, lubrication being secured automatically, when required, by a supply of vaseline that melts if any part becomes hot.
She stole a look at him while he and Claybrook were discussing lubrication and wondered in what way he had changed. A sureness? A steadiness? A bit of reserve that sat well upon him? All of these, surely. She had never seen him show to better advantage. Once he turned to her and asked her opinion about the leather. There was an air of quiet deference in the way he put the question.
On operation number thirty-four the budding motor gets its gasoline; it has previously received lubrication; on operation number forty-four the radiator is filled with water, and on operation number forty-five the car drives out onto John R. Street. Essentially the same ideas have been applied to the assembling of the motor.
