But I am defeated utterly by the man who talks about escapements, compensating balances and clutches. I suspected that Tim Gorman would pelt me with even more recondite scientific terms if I let things go on. "You may take my word for it," I said, "that you'll get a thousand dollars and more, in the end; but you may have to wait for it.
But the watch is even more in the right still, for its maker, man, virtually has the cogged wheels, springs, escapements, oil, &c., which the watch's conception has been supposed to attribute to him; inasmuch as all these parts must have existed as distinct ideas in the human watchmaker's mind before he could actually construct the clock formed by him.
Hooke, the contemporary of Newton, gave it the balance-wheel, with the spiral spring, and various escapements in succession were devised, such as the anchor, the dead-beat, the duplex, the remontoir. Provisions for the variation of temperature were introduced. It was brought to perfection eventually by Harrison and Arnold, in their hands becoming an accurate measure of the flight of time.
The teaching of this part is very important as regards the manufacture of escapements. In constructing the dial train, the pupil perfects his filing and learns to make the adjustments correct. Here, as in the preceding classes, the pupils must do all the work themselves.
The vertical rods C, which actuate the escapements, are guided in the main frame, and each is urged downward by a spring c. Each rod C terminates directly over one end of a rising and falling yoke-bar c2, turning on a pivot c3 at the opposite end. Each of the yokes c2 is slotted vertically to admit an eccentric c4 turning on a pivot therein.
It is evident that the escapements could be operated directly by rods connected with the finger-keys, but this direct connection is objectionable because of the labor required on the part of the operator, and the danger that the keys may not be fully depressed.
