The cap 0 fits very closely over and counter, which is shownin elevation.

Even then the counter, which is in the upper part of the cap, will not be reached by the moisture, and, as is obvious, said counter will be protected until the odometer-casing is literally flooded with water.

The main shaft f, to which the star-wheel or actuated member 9 is keyed, is jo'urnaled in the extended part of the base (1, bearings h being formed therein for the reception of said shaft, while the bearing next the starwheel is extended somewhat to resist the lat eral thrust of the shaftf when the odometer is run at high speeds. Said shaft is locked in the odometer-casing by a key 1', which fits in'a peripheral groove or keyway on the end of the shaft, and a dust-cap j, containing suitable packingj, is provided around the shaft between the star-wheel and the casing to prevent the entrance of dirt or moisture into the instrument at that point.

Mounted upon the main shaft and secured to the same so as to rotate therewith is a pinion 7a, which engages a similar pinion Z, keyed to the shaft of the counter or registeringmechanism. Alsomonntednponthemain shaft so as to rotate therewith and to be movable longitudinally thereon are disks wt, preferably of steel, and in alternation with said disks are friction plates or washers or, preferably of fiber, said friction-plates being squared to fit the chamber 6 and being held thereby from rotation. These disks and friction-washers constitute a braking device for preventing the star-wheel and shaft from spinning when the star-wheel is actuated in rapid succession. Suitable means are provided for keeping said disks and washers in close contact, such means being preferably a set of springs 0, seated in a spring carrierblock 1), fixed to the sides of the casing. Said springs bear against one of the washers 71 at one end of the braking device, while a plate q, fixed to the sides of the casing, is provided at the other end of the device and receives the thrust of the springs 0.

In order to secure the disks it to the shaft fin the manner above stated, said shaft is formed with one or more longitudinal grooves or keyways f and the disks with corresponding projections m, adapted to fit in said grooves. In the same manner it is preferable to secure the pinion 7.; to said shaft. In assembling the parts of the odometer the pinion 7.:, thrust-plate q, disks m, friction-washers n, and spring carrier-block p are first placed in their respective positions in the chamber or inclosure c and then shaftf inserted through the openings in the center of all of said parts, the keyways f in said shaft receiving the projections on the disks 7t and pinion 7s. The shaft is then looked in position by the key t. Inasmuch as the chamber c, as well as the upper part of cap 0, are symmetrical, the positions of the braking mechanism, pinion 7t, and the counter or registering mechanism a with respect to the casing may be reversedthat is, the positions of the pinion 7; andthrust-plateqontheonehand and the spring carrier-block p on the other hand may be interchanged and the counter a so placed in the top of cap 0 as to cause pinion Z to engage pinion it in its new position. Because of this reversibility of the mechanism of theinstrument it becomes possible to mount the instrument with respect to the actuating member-the wheel of the vehicle, for instance-in two different positions with respectto said member or wheel,while the readings of the counter are visible in an upright position from either side of said member or wheel, as may be desired. When the instrument is in operation, motion is transmitted from the actuating member, usually a pin on the spoke of a vehicle, intermittently to the star-wheel, and said wheel is in rotation only during the time that the pin and the starwheel are in contact, the braking mechanism causing said wheel to stop as soon as the pin or actuating member becomes disengaged from the star-wheel.

In a modification of the odometer shown in Fig. 8 the star-wheel has been omitted, inasmuch as this form of the instrument is designed to be actuated by some suitable mechanism for supplying a continuous motion to the main shaftf instead of intermittently, as in the previous case. The braking device has also been omitted, as the shaft f is at all times directly connected with the actuating member,and therefore is not left to spin freely when the-instrument is running ata high speed. If the counter or registering mechanism in this modification is similar to that in the form of the instrument first described, means for effecting the proper speed reduction should be interposed between the main shaft and the shaft of the counter. This speed reduction may be effected simply by increasing the size of the pinion Zon the counfer-shaft and by reducing the size of pinion 7t" on the main shaft, the ratio of the sizes of the two pinions shown in the drawing Fig. 8 being five to one.

In Fig. 9 still another modification of the instrumentisshown. Herethecountermeclv anism (not shown) is separated from the main shaft and placed in a location where it may be conveniently observed, being connected to the main shaft by a flexible shaft or some other suitable means for transmitting motion. The braking device, the main shaft, and the star-wheel are similar to those already described with reference to the first form of the instrument above referred to, while the cap 0, which no longer contains the counter mechanism, is made to conform substantially to the shape of the chamber or inclosure c of the braking mechanism.
