SPECIFICATION forming part of Letters Patent No. 513,040, dated January 16, 1894.

Application filed September 22, 1892. Serial No. 446,567. (No model.)

fo all whom t may concern:

Be it known that I, OSCAR J. FUCHS, of Chillicothe, in the county of Ross and State of Ohio, have invented certain new and useful Improvements in Cyclometers; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

Myinvention relates to improvements in cyclometers, and which is intended especially for use in connection with bicycles, and it consists in the construction, combination and arrangement of parts which will be fully described hereinafter and particularly referred to in the claims.

The primary object of my invention is to provide a cyclometer adapted to be connected to the frame of a safety bicycle77 adjacent to the driving sprocket wheel, and which has a lever extendinginto the path traveled by a suitable operating device connected with the said sprocket wheel.

The object of my invention, further consists in the construction of the mechanism Within the cyclometer, whereby it registers the distance by one mechanism continuously for great distances, and with a second mechanism whichregisters the distance for shorter `distances, the latter being adapted to be set before starting on a trip, and thus register the distance traveled, while the long distance mechanism registers continuously and independent thereof.

Another object of my invention is to so construct the cyclometer, that it is adapted to be applied to and operated by a machine having the driving sprocket thereof upon either the right or left hand side of the machine.

My invention still further relates to the particular construction of the registering mechanism, all of which will be particularly pointed out hereinafter.

Fig. 10 is a View of one of the ratchet wheels that are feathered upon the sleeves. Fig. 11 is a view of one of the cams that are feathered upon the sleeves. Fig. 12 is detached side view of the operating lever that is secured to the operating shaft. Fig. 13, is a detached view of two of the disks m, one being broken away to show the operative relation of the parts. Fig. 14, is a detached perspective View of one of the disks employed in the mechanism shown at the left of Fig. 3, the same showing the resetting spring and stop.

A is a bicycle of any make and style, and to which the inclosing case B of the cyclometer is secured by means of a band C which encircles the said casing, which band has two laterally projecting arms D, adapted to extend upon opposite sides of any convenient and properlysituated partof the bicycle frame in relation to ythe driving sprocket wheel. These arms are clamped to the frame of the machine by means of a clamping bolt E which passes through them as illustrated. The band C is provided with a longitudinal slot F, through which a clamping screw passes, and by means of which .the casing is allowed to be revolved within the band to adj ust it for the purpose to be fully described farther on. This clamping screw Cr, which passes through the slotted band, is made sufficiently long to extend into the casing, and into the stationary portion of the mechanism, for holding it in place, as will appear farther on.

Placed within the casing, are the two disks H, which are held therein by means of the screw G as j ust stated. These disks are separat-ed by means of blocks I, and are also connected and held firm in relation to each other IOC by means of screws which pass through the said disks into the blocks.

Extending outward from each disk and rigidly secured thereto is a longitudinally slotted sleeve J. Passing through these sleeves, the stationary disks secured thereto, and through the ends of the casing, is an operating shaft K, which has an oscillating motion, as will be described farther on. The oscillating movement is given to this shaft, by means of an operating lever L, which is journaled upon a sleeve M, that is connected to the said shaft by means of a screw, or in any other suitable manner, so that the shaft is moved when the sleeve is actuated. Formed as a part of this sleeve, is an arm N, and connecting the arm and the operating lever is a spring P. Either the arm or the lever is provided with a stop Q, so that when the lever is moved in one direction the arm is moved with it, and thereby the shaft moved, but when the arm is moved in the other direction, it has a movement independent of the arm and sleeve and underthe tension of the spring P. Connected with the sprocket wheel of the machine at a suitable point is a clamp R, which carries a roller S, and this roller as it revolves engages the lever, and-moves it. The direction of movement of the lever by the said actuating device, is against 'the stop between the lever and the sleeve arm, so that the operating shaft of the cyclometer is moved. The distance the shaft is moved, is of course regulated bythe relative position of the lever and the sprocket actuating device, that is to say, by the distance that the free or lower end of the lever extends below the path traveled by the sprocket actuating device. Now when the bicycle is moved backward, the said device upon the sprocket wheel will engage the4 lever, but the lever is allowed a free movement in that direction against the tension of the spring P, and independent of the arm N, so that the device will neither be operated backward, nor any parts of the cyclometer broken. After the device R has passed the lever, the spring Pcarries it toits normal position to actuate the arm N when the machine is moving forward.

It being now understood that the operating shaft has an oscillating movement, and the manner in which this movement is eifected, I will now describe the registering mechanisms whieh are operated by the movement of the shaft. Connected rigidly to this shaft, and between the two stationary disks H, is an arm T, and pivoted upon this arm T is a spring actuated pawl U. Journaled in these disks and having its ends extending through them, is a shaft c, upon which is secured between the said disks a ratchet wheel b, with which the pawl U engages. Thus it will be seen, that as the shaft is oscillated, the pawl U engages the ratchet wheel, and revolves the shaft a. A spring c, is secured between the disks, and the free end of this spring engages the said ratchet wheel, wherebyit is prevented from having any backward movement, when the pawl is being drawn over its teeth to be again moved forward for revolving it. The movement of the shaft is sufficient to have the pawl engage one tooth upon the ratchet wheel each time it is actuated, and the said shaft is held normally in this backward position by means of a coil spring d, that is placed within acircular iiange e, of the removable end f, of the casing. Attached to this end of the said shaft is a sleeve g, which has its end extending through the end and into the casing, and this end is provided with a stud e that engages the inner end of the said spring in the same manner as the winding arbor of a watch main spring. The strength of this spring, or rather its tension is readily regulated by means of the said sleeve, that is, the sleeve can be revolved until the proper tension is secured, and then fastened to the shaft by means of a set screw.

Placed loosely upon, and revolving independently of the sleeves J, which extend in opposite directions from the disks H, are the pinions or cog wheels h, and these cog wheels are moved one notch at each revolution of the shaft d, by means of a spur t', which extends laterally from the said shaft and engages the teeth of the wheel. There is one of these wheels at each side of disks H, one for operating the mechanism which shows through an opening j, in the casing, and which registers miles to ten thousand, and the other for operatin g a mechanism which shows through an opening k, which registers miles to one hundred. This last mechanism is constructed (as will hereinafter appear) to be set to zero at any time, while the other mechanism is designed to register continuously, without being set.

The objectof having a mechanism for registering hundreds of miles, which is independent of the other mechanism, is that the one registering hundreds can be set whenever the rider starts out for a trip, and the distance registered without any subtracting, which is necessary where a single mechanism is used, while at the same time the other mechanism continues to register uninterruptedly, and indicates the total number of miles ridden from the time the cyclometer is first attached. Each of these mechanisms is alike, and the construction and operation of one will be described, which will describe the other, and enable it to be fully understood.

It having been shown how the pinions h are 'revolved by the shaft a, and it in turn by the shaft K it will now be described -how the registering and indicating disks fm, are revolved. Each of the pinions h, is provided with outwardly projecting studs or pins n, which extend into an opening made in the disk fm, which is next to it, so that the said adjacent disk is revolved therewith, and also independently of the sleeve J Each of these reg istering disks is made cup shaped as shown, and placed within them are the pivoted spring IIO ' thesecam-shaped plates are provided with projections s, which engage the longitudinal groove ofthe sleeve, whereby they are not allowed to revolve.v The operating end of the pawls p, engage the periphery of these camshaped plates, so that the free operating ends of the pawls are forced down into the cut away portion of the plates by its spring once for each revolution of the said indicating wheel, as will be understood. Now the next vadjacent indicating wheel, is provided on its adjacent side to the said cam-shaped plate with the cog wheel t. wheel carrying the pawl has revolved to bring the free operating end of the pawl tothe cutout portion of the cam-plate, the pawl will drop therein and engage the cog Wheel t, of the adjacent indicating wheel,`and thus revolve the next indicating wheel one notch only, for the said pawl `is raised from engage ment with the wheel @before it can revolve it further. 1n order to prevent this outer and adjacent indicating disk from movement by contact with the inner indicating disk, a

ratchet wheel u, is placed upon the sleeve J, and inside of the cam-plate, and this ratchet wheel is feathered upon the sleeve in the same manner as the cam-plate so that it too is not revolved but remains stationary. Secured to the disk is aspring c, which engages the teeth of this cog wheel, and by frictional contact therewith the disk is prevented from revolving, except when positively operated by the pawl p. Each of the indicating disks throughout the train thereof is similarly constructed, whereby when the inner disk has revolved one revolution, theunextdisk is moved only one notch, and when this last one has made one revolution the next is moved only one notch, and so on throughout the train, whereby the revolutions of the ratchet wheel upon the shaft a are registered, and the distance of travel of the bicycle thus given, in

the ordinary manner of registering with cyclometers. The outer indicating disk of each train is not of course provided with a camplate, for none is needed, nor are the inner indicating wheels provided with cog wheels t, for none are needed, it being revolved by the pinion h. The peripheries of the indicating disks are provided with numerals from l to O, in the usual manner, and they show through the openings in the casing. The only difference between the one thousand and one hundred register mechanisms is, that the former has a greater number of wheels.

For the purpose of setting the hundreds registering mechanism to zero when desired, a thumb nut tu, is journaled in one end of the casing, preferably the end which is rigidly secured therein, and this thumb nut is provided with an arm @which is attached to its inner end within the casing. The operat- When the indicatingy ing shaft it will of course be understood, passes through a central'openin g made in the said nut. This arm engages a projection y, extending within the indicating outer disk, whereby this disk can be revolved, and each disk is provided with a spring z, which engages either a projection or opening a. made in the next adjacent disk. These springs zyextend in a direction which allows the indicating wheels to freely revolve in the registering direction, but when revolved in the opposite direction will engage the adjacent wheels, and cause them all to revolve together.

The ends of these springs and the openings or projections which they engage upon the respective indicating wheels, will be so placed in relation to each other, that when they engage, the figure 0 upon each wheel will be in a line with the same figure upon the adjacent wheels, thus setting the mechanism to zero,I

as will be readily understood.

The operating lever can be secured to either projecting end of the operating lever, so that the cyclometer is adapted for either right or left sided sprocket wheel machines, and owing to the manner of holding the casing, the same can' be placed in the proper relative position to the sprocket wheel, and the operating device R carried thereby, that the operating shaft will be given the proper relative movement for operating the mechanisms.

The cyclometer will be adapted for different sized wheels, by means of the ratchet wheel upon the shaft a, having more or less cogs, according to the size of the wheel, and the number of revolutions made thereby in traveling a specified distance.

While I have described my invention in connection with and especially intended for use in connection with bicycles, it will be understood that it can be applied to other vehicles, and I do not therefore desire to limit myself to any particular application thereof.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
