SPECIFICATION forming part of Letters Patent No. 632,332, dated September 5, 1899.

Application tiled January 25, 1898. Serial No. 667,846. (No model.)

To all wiz/0712, t may concern:

Beit known that I, JAMES E. BEAN, of Fond du Lac, in the county of Fond du Lac and State of IVisconsin, have invented a new and Improved Cyclometer, of which the following is a full, clear, and exact description.

The invention relates to cyclometers for use :on bicycles and other vehicles; and its object is to provide new and improved cy` ro clometer arranged to indicate simultaneously the number of miles traveled during the season and the number of miles of the individual trip made at the time.

The invention consists of novel features, ri5 parts, and combinations of the same, as here`- inafter more fully described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart of this specification zo in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a cross-sectional elevation of the improvement. Fig. 2 is a sectional side elevation of the same on the line 2 2 of Fig.

z 5 1. Fig. 3 is a sectional plan view of the cas ing, showing the transmittinggearing Fig. /I is a sectional side elevation of the trip-register. Fig. is an edge View of the unitswheel for the total register and adjacent 3o part-s. Fig. 6 is a face view of the same with parts in section and parts broken out. Fig. 7 is an end elevation of the spring for the fraction numeral-wheel. Fig. 8 is a face view of the paWl-and-ratchet mechanism for the fraction-Wheel. Fig. 9 isa side elevation of the setting-arm; and Fig. l0 is a detail perspective view of the mechanism for operating the numeral-wheels, parts being broken away.

The improved cyclometer is provided with a casing A, preferably made cylindrical in form and provided at its lower end with a dovetailed boss A', on which is adjustably secured a bracket B, adapted to be clamped i5 or otherwise fastened to the axle of the steering-Wheel when the device is applied to a bicycle.

0n the casing A, adjacent to the boss A', is

formed a bearing A2, in which is journaled a 5o vertically-disposed shaft C', carrying at its outer end a star-wheel C, adapted to be engaged by a friction-roller D, journaledon a shaft D', carried by a clamp D2, adapted to be fastened on one of the spokes E of the steering-Wheel, so that the latter at every revolution brings the friction-roller D in mesh with the lstar-Wheel to impartan inter mittent rotary motion to the same and to the shaft C'. In order to prevent the wheel C from being carried too far by the friction-rol- 6o ler D, I provide a friction-cap C2, fitted to slide loosely on the bearing A2 and pressed outward by a spring C3 to hold the outer end of the said cap in frictional contactwith the inner side of the star-wheel C. A lug C5 in 65 the friction-cap C2 tits in a groove in the bearing A2 and prevents the cap from turning around and Wearing out the spring.

On the inner end of the shaft C' is secured a pinion C4 in mesh with a gear-Wheel F, 7o mounted to rotate on a stud F', secured to the casing A, and on the upper face of the said gear-wheel F is formed a worin F2 in mesh with a pinion G, secured on the shaft G', journaled in suitable bearings within the casing A. On the shaft G' is secured a second pinion G2, and the pinions Gand G2 are at all times in mesh with gear-wheels II and I, of which the latter forms part of the mechanism for actuating the trip numeral-wheels J, J', 8o and J2, 'and the gear-wheel II forms part of the mechanism for actuating the numeralwheels K, K', K2, and IT3 for registering the number of miles made during the season. The numerals on the pcripheries of said Wheels J, J', and J 2 and those on the peripheries of the other set of numeral-wheels K, K', K2, and K3 are visible to the rider of the cycle through a transparent or translucent strip A3, iitted in an opening formed in the 9o peripheral surface of the casing A, as is plainly indicated in Figs. l and 2. The sets of numeral-Wheels J J' J2 and K, K', K2, and K3 are arranged one alongside of the other, so that the rider is enabled to see at a glance the number of miles made during a trip, and also the total number of miles made so far in the season. The numeral-wheel J is a fraction-Wheel,the wheel J' is the units-Wheel, and the Wheel J2 is the tens-wheel for the 10o trip-registering device; Y The Wheel K is the units-Wheel, the Wheel K' is the tens-wheel,

the wheel K2 is the hundreds-wheel, and the wheel K3 the thousands-wheel for the totalregister. Each of the wheels, however, hears the numerals from O to 5).

The trip-registering device is arranged as follows: The gear-wheel I is connected by a pawl-and-ratchet mechanism L with the hub J3 of the fraction-wheel J, the said huh being mounted to turn loosely on abearing N, having a polygonal aperture iitted on the correspondingly-shaped outer face of a sleeve A, forming part of the cap A4, closing one end of the casing A, the other end being closed by a cap The sleeve A is mounted to turn loosely on the enlarged end O of a shaft having its reduced end O' extending in a sleeve AT attached to the other cap A5. On the inside of the rim of the fraction-wheel J is secured a spring-pawl P, the free end P' of which rests on the peripheral surface of a toothed disk Q, secured on the polygonal sleeve A, the said wheel having the same number of teeth as there are numerals on the numeral-wheels, and the said disk is also provided at one portion of its periphery with a recess Q', so that when the free end of the spring P drops into this recess it comes in contact, by means of a sidewise-projeeting tongue P2, with a tooth of a toothed wheel J4, formed or secured onthe web of the unitswheel J', so that the further rotation of the fraction-wheel J rotates the units-wheel J' to bring the next numeral to view under the strip A2, and when this takes place the free end of the spring P' travels up the next following tooth on the disk Q, so as to raise the tongue P2 out of engagement with the corresponding tooth of the wheel J4, so as to free the wheel JAl and allow it to turn. The spring P has its lower end P3 curved inward to form a dog for the disk Q to prevent accidental return movement of the disk. Now it is evident that the gear-wheel l moves along the fraction-wheel J, and the latter when completing a revolution moves the units-wheel J' such a distance as to bring the next numeral under the strip A3, and when the wheel J completes a revolution it carries the tens-wheel J 2 along by means of a similar spring P and a disk Q2, the said tens-wheel being provided with a toothed wheel J 5, similar to the wheel J The tenswheel J 2 is provided with a spring P, engaging a disk Q2 without a recess Q', the said spring and disk serving to prevent the wheel J2 from being carried too far by the wheel J', as previously explained. The gearing from the star-wheel G to the gear-wheel l is so proportioned that when the wheel I has made one complete revolution the bicycle has traveled one full mile and the units-wheel is shifted accordingly. lVhen the units-wheel moves from 0 7 to 0, it shifts the tens-wheel to the next following numeral, as is well known. On the peripheral surfaces of the units and tens wheels J and J2 are secured stop-pins .1, extending outward from the rims ol the said wheels, and said stop-pins are adapted to abut against the upper edge of the springarm R, secured to the inside of the casing. rlhe cap A'l is provided with an arm A7, adapted to be taken hold el by the operator to turn the said cap on the sleeve A(i when it is desired to move the several wheels J, J', and J2 back to O when starting on a new trip, and it also serves to hold the spring-arm in place while in use, and for that purpose has a depression on its inner side to lit over a small projection near the corner of the case. (See Fig. 0.) New it is evident that when the operator turns the handle or arm Alfrom the left to the right in the direction of the arrow a' in Fig. 2 then the several wheels J, J', and J2 will turn with the cap and its integral sleeve A, owing to the pawl-and-ratchet connection between the wheel I and the hul) N and the connection of the springs P with t-he fixed disks Q, Q2, and Q2. Now as soon as the numeral O of the wheel J appears under the strip A3 the operator turns the handle AT in the inverse direction of the arrow d' until the stop-pins JG move in engagement with the arm R, so as to prevent `further rotation of the units and tens wheels. The tripregister is now set at 0.

The totalamount register has its gearwheel H mounted to rotate loosely on a bearing N3, secured to the polygonal external snrface of the sleeve AT, and on this gear-wheel is secured a spring S, having its free end in peripheral contact with a disk T, formed in part of its surface with a recess 'l'. Adjacent to the disk Tis arranged the toothed wheel K', formed or secured on the web ol' the units-wheel K, so that when the spring S drops at its free end into the said recess 'l" of the disk T it moves in contact with one of the teeth of the wheel K", so that the further rotation of the gear-wheel H causes the spring to carry the toothed wheel K'L along` with it, and consequently the units-wheel K, so as to bring its numeral to the next position under the strip A2. lVhen this takes place, the free end of the spring travels up the peripheral surface of the disk T and out of mesh with the corresponding tooth ofthe wheel Ki. The units-wheel K is mounted to turn on a bearing N4, held on the sleeve A7, and it is provided with a spring P", similar to the spring P and engaging a disk Q1, similar to the disks Q, Q2, and Q3, and the said spring is adapted to engage a toothed wheel QA1 on the tenswheel K', which in turn is similarly constructed to the wheel K, so as to actuate at every revolution the hundreds-wheel K2, which in turn actuates by a similar mechanism the thousands-wheel K2. Now it is understood isterin device.
