Extending upwardly from the odometer box is a lug 20 in which is pinned a shaft 21, parallel to the axis of the casing. On the ends of the centers, are two arc-shaped depending arms forming a circular element the cylindrical inner contour but. slightly smaller than the casing soas to leave a space between the. two, as The parts of this'elenient are preferably indiameter of the said circular element are' suitable anti-friction devices, asthe balls 24, to-bear on the inner walls of the. casing reason of the-weight the center of gravity of the combined welght, arms, odometer,

is not open to the objection heretofore urged against pendulously supported cycloineters, namely, the niore'or less extensive swinging towhich they, may at times be subject and which might interefei'e with proper actuation of the registering mechanism. on the contrary the oscillation'in my device. is necessarily very limited in extent and is t0.0 slight to haveany-appreciable etlect on the operation of theodome'ter;

For the purpose of actuating the odour cter 16 the shaft. 30 of the latteris pi;o-

vided at one end with a ratchet 31 engaged above and below by'twh paivls '32, 33, mounted'on the depending end of an L-shaped' member or wig-wag 34 and held in engagement with the ratchet by light. bladesprings 35, The horizontal portion of the wig-wag extends through an opening 36 in j the lug 20 on" the 'odometer box and is piv-. oted to the latter at 37. On the side edges of the depending portion of the oscillatory.

member or wig-wag are two wear,platesf 38, hearing on two cam rings 39, 40, fixed on the front and rear 'alls of the casing and hence revolving therewith. These cams'are alike in contour, but are arranged with the low portion of one opposite the high portion of the other, so that as they revoli'ie the member 34 will be swung on its pivot 37 first in one direction and then in the other, thereby reciprocating the pawls 32, 32}.. 'Thc swing of the member. toward the left, as 'viewedin Fig. 52, retracts the pawl 32 and advances the awl 33 and the ri ht-- It will therefore be seen that my improved device ward swing advances pawl 32 and retracts pawl33, thus giving the ratchet two imone complete oscillation, that is, an iexcursion in each direction, in each revolution of the casing, and this is sufiicient to make the actuation. ofthe odometer practically con t-inuous, especially if the casing is revolving rapidly. It will of course be seen, however, that by suitable design of the cams the actuating member maybe given any number of oscillations 'per revolution of the wheel, within certain limits determined by the inertia of the member, the increasedwear on the plates as the rapidity of oscillation is increased, etc. The useiof two pawls is also advantageous in that the retreating pawl "ser ves' as a brake, thereby preventing over rii n' of'the ratchet by the momentum of the moving-parts and hence obviating'the 'use of special damping devices or the like.
