7845. Hopkins, C. Y. April 27. Odometers.-In a cyclometer or similar instrument for recording distances travelled by road vehicles and counting the revolutions of rotary parts, the casing a, Fig. 9, and core c are formed of a solid piece of metal in which an annular space is bored to receive the annular numbered wheels d. A recess is bored in the core to receive the transmitting and locking pinions e on a spindle n engaging holes in the casing and a bearing-plate n2. The spindle g, carrying the operating star-wheel h, has an eccentric enlargement g3 carrying two rigidlyconnected pinions f, f2 of different pitch and engaging the teeth of a fixed annulus o and the outer ring d. The star-wheel is protected by a partially cut-away end plate h4. The casing has a closing- plate o2, and carrier a cylindrical &c. rib s adjustable in an eyed-plate t, Fig. 10, having a bifurcation t3 clamped by a screw pin engaging a gripping- piece w2. The eyed-plate may be clamped on the end of the spindle of a cycle wheel.
