Abstract

157,532. Crocker, S. H. Oct. 14, 1919. Driving-mechanism, main spring.-A substitute for the chain and fusee is provided. A pair of conical drums 1, 2 in contact along a directrix has a spiral line of holes 13 or 14 running round each member, and one member encloses a shaft 9 which is fixed parallel to the line of contact and carries a toothed loose wheel 12. Initially a tooth of this wheel projects through both the first hole of the enclosing-drum and the last hole of the fellow drum. As one of the drums is turned the succeeding holes and teeth engage together and effect the rotation of the second drum while the wheel travels parallel to itself towards the other end of the drum.
