SPECIFICATION forming part of Letters Patent No. 583,491, dated June 1, 1897. Application filed OCtObST 24, 1896. Serial No. 609,979. (No model.)

To all whom, it may concern:

Be it known that l, CHARLES S. LABOFIsH, a citizen of the United States, residing at Williamsport, in the county of Lycoming and State of Pennsylvania, have invented a new and useful Cyelometer, of which the following is a specification.

My invention relates to cyclometers, and has for its object to provide a device of this io class which is simple in construction and is adapted to accomplish the registration of distance when applied to a vehicle, such as a bicycle, with the minimum number of operating parts and without the use of gearing for I5 communicating motion from one registering wheel or member to the next of higher denomination.

Further objects and advantges of this invention will appear in the following descrip- 2o tion, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective View. Fig. 2 is a longitudinal central section of the same. Fig. 3 is a similar view showing the registering-wheels in elevation. Fig. 4 is a transverse section on the line 4 4 of Fig. 2. Fig. 5 is a transverse section on the line 5 5 of Fig. 3.

3o Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

1 designates a cylindrical casing having one end open and fitted with a removable head or cap 2, which in the construction illustrated is threaded in the end of .the casing. This removable head or cap carries an arbor 3, which is located axially in the casing, and upon it are mounted rotary registering members or wheels respectively designated by the numerals 4, 5, G, and 7, bearing numerals for exposure through inspection-openin gs S in the shell or casing and occupying such relative positions as to arrange the exposed numerals,

respectively, in the units, tens, hundreds, the., places. The units registering member or wheel 4 is held from displacement by a terminal enlargement or head 9 on the inner end of the arbor 3, andthe wheels are spaced at 5o the desired intervals by means of interposed collars 10. A suitable transparent shield 11 covers the openings S to prevent the access of dust and moisture to the interior of the casing.

Located exteriorly of the shell or casing is a star-wheel 12, adapted to receive motion from the wheel of the vehicle, and to the spindle 13 of the star-wheel is fixed a driving-gear 14, having a smooth circular periphery, except at one end, where it is provided with a 6o radial spur or tooth 15, the contiguous portions of the periphery upon opposite sides of said spur or tooth being cut away to form depressions 16. Arranged in operative relation with the driving-gear is a toothed pinion 17, adapted to receive motion from the gear 14, and hence having its teeth 17n located in the plane of the detent 15 for successive engagement thereby. Hence each complete revolution of the gear 14 will advance the 7o pinion 17 a distance equal to the interval between two contiguous teeth 17, and in order to hold said pinion from accidental movement, as by the jarring of the device, the circular periphery of the gear projects into the paths of the contiguous teeth 17 or extends slightly between said teeth. This forms a lock to prevent the movement ofthe pinion, and the latter is only released when the notch or depression 16, located contiguous to the spur Se 15, comes into alineinent with the tooth which is about to be engaged by said spur. As soon as the spur has advanced the pinion one step the circular periphery oi the gear again locks the pinion against further movement until the gear has completed the next revolution. The pinion 17 also carries the spur 1S, which is designed for successive engagement with seats or notches 1i) in the units-registering member or wheel 4, said seats or notches be- 9o ing formed in the cross-sectionally iiat circular rim 4, which combines .with a web 20 to constitute the registering member or wheel. It will be seen that as the pinion 17 completes a revolution the spur 18 will engage one of 95 the seats or notches 19 and advance the unitsregistering member or wheel one step, or the distance between contiguous seats or notches.

1n order to accomplish the communication of motion from one registering member or ico wheel to the next of higher denomination, I preferably construct the same with yielding 2 sesam webs 20, whereby the rims are laterally resilient. This quality of the registering members or wheels enables them to be moved to secure the engagement or interlockingof the rims, the rim of each wheel of lower denomination being provided with a lateral stud or projection 2l to engage one of a series of seats or notches 22, formed in the rim of the adjacent wheel of higher denomination. Hence by imparting lateral movement to the unitswheel it may be brought into interlocking engagement (by neans of the stud 2l and one of the seats or notches 22) with the tenswheel to cause an advance movement of the latter, and the means illustrated in the drawings for accon'iplishing this lateral movement of the units-wheel include cooperating movable and fixed cams 2.5 and 2-t, carried, respectively, by the units-wheel and the shell or casing, and shown, respectively, in Figs. 2 and 3. lVhcn the units-wheel has completed one revolution, the projecting cam 2S comes in contact with the cam 2land forces the rim of the units-wheel toward the tens` wheel sufficiently to cause the engagement of the stud or projection 2l with one of the notches 22, and hence while the movable cam is traversing the surface of the fixed cam the tens-wheel is moved forward one step, or a distance equal to the interval between contiguous notches 22.

In order to communicate motion from the tens-wheel to the hundreds-wheel, it is necessary to lock the hundreds-wheel to the tenswheel long enough to secure the advance movement of the former through a distance equal to the interval between contiguous numerals. The tens-wheel is provided with a stud or projection 2l for engagement with seats or notches 22'L in the rim of thehundreds-wheel, but the coactin g cams 23 and 24: are capable of moving the units-wheel laterally a sufficient distance only to secure the engagement of the stud 2l of the units-wheel with the seats or notches 22 of the tens-wheel, whereas it is necessary that motion should be communicated from the units-wheel to the tens-wheel in order that the stud 2l may be brought into engagement with one ot' the notches 22. In order to accomplish this, I reduce the depth of one of the seats or notches in the tens-wheel, as shown at 22h, the bottom of this shallow notch being arranged out of the plane of the notches 22 and closer to the rim of the wheel il, whereby when the tens-wheel is about to complete one revolution and the units-wheel is deflected laterally to interlock its rim with that of the tenswheel the stud 2l engages the notch 22h, and as lthis notch is shallow the tens-wheel will also receive lateral movement sufficient te cause its rim to interlock with that of the hundreds-wheel by the engagement of its stud 2ln with one of the notches 22". In the same way when the huinlreds-nf'heel is about to complete a revolution the forward motion of the hundreds-wheel is communicated thereto by reason of the engagement of the stud 2]. with a shallow or reduced notch 22c in the humlreds-wheel.

Frein the above description it will be seen that motion is communicated from one wheel to the next of higher denomination by reason of the laterally resilient or yielding construction of the wheels, `which are provided with rims having interlocking projections and dcpressions, said projections and depressions being brought into operative relation by the deflection of the wheels from their normal positions, and the subsequent disengagement of said rims to avoid communicating excessive motion being secured by the resilience of the webs 20.

ln order to prevent accidentaldisplacement of the registering members or wheels, l preferably employ a locking device consisting of a yielding spring-actuated locking-pin 25, mounted in a cavity 2G in the arbor in the plane of each wheel, to engage one of a 'series of notches 27 formed in the hub of the wheel.

It will be understood that in practice various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

llaving described my invention, what I claim is l. In a cyclometer, the combination with a plurality of coaxial registering members or wheels having transversely-resilient rims provided with interlocking projections and dcprcssions, and means for detlecting the rim of each member or wheel of lower denomination to bring it into operative relation with the rim of the contiguous wheel of higher denomination, substantially as specified.

2. ln a cyclometcr, the combination of a plurality of coaxialtransversely-resilient registering members or wheels having projections and depressions normally held out of engagement and adapted to be intcrlocked by the lateral deflection of a wheel of lower denomination toward the contiguous wheel of higher denomination, the wheel of lowest denomination being provided with a cani-face to coact with a stationary projection, substantially as specified.

In a cyclometer, the combination of a plurality of coaXially-mounted registeringwheels having rims provided with complemental interlocking faces, said rims being supported by transversely-yielding webs, and means for imparting transverse movement to the rims to bring those of lower denomination in interlocking relation respectively with those of higher denomination, substantially as specified.
