Publisher's Synopsis
Excerpt from On the Springing and Adjusting of Watches: Being a Description of the Balance Spring and the Compensation Balance With Directions for Applying the Spring and Adjusting for Isochronism and Temperature
In the second watch the verge escapement was arranged in the ordinary way, the balance being mounted on a verge with two pallets; on the verge was also a toothed wheel which engaged with another of the same size mounted on a stud, and the pipe of this wheel carried the second balance the toothed wheels being of small size one balance was placed a little higher than the other and overlapped it. Each balance was controlled by a balance spring.
However, Hooke turned his attention to other matters, and in January, 1673, Huygens addressed a letter to Henry Oldenburg, secretary of the Royal Society, in which he described as his invention the application ofa spring to control the balance in watches. This aroused the wrath of Hooke, who accused Oldenburg of having divulged the discovery in his correspondence with Huygens. Hooke enlisted the interest of Charles II and in a lecture, entitled Potentia Restitutiva, &c., said, His Majesty was pleased to see the experiment that made out this theory tried at Whitehall, as also my spring watch.
