FRED )L CARROLL, OF UNION CITY, PENNSYLVANIA, ASSIGNOR OF ONE- IIALF TO JAMES E. BEEBE, OF SAME PLACE.

CYCLOIVIETER.

SPECIFICATION forming part of Letters Patent No. 552,819, dated January '7, 1896.

Application led May 13, 1895x To @ZZ whom t may concern/ Be it known that I, FRED M. CARROLL, of Union City, in the county of Erie and State of Pennsylvania, have invented a new and Improved Oyclometer, of which the following is a full, clear, and exact description.

My invention relates to an improvement in cyclometers, and it has for its object to provide a machine of this description which may be expeditiously and conveniently attached to any vehicle, and wh ich, in addition to registering the aggregate number of miles traveled by a vehicle during a specified time, will be provided with an independent registering device,which will show the number of miles traveled each d ay, the auxiliary or day registering device being entirely independent of yet operated from the device adapted to register the aggregate number of miles.

A further object of the invention is to construct a cyclometer embodying all of the features above set forth, in which the mechanism will be simple, durable, and economic.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this s peciiication, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the complete cyclonieter. Fig. 2 is a vertical section taken through the same at a central point. Fig. 3 is a horizontal section taken on the line 3 3 of Fig. 2. Fig. 4: is a horizontal section on the line a 4: of Fig. 2, and Fig. 5 is a horizontal section on the line 5 5 of Fig. 2.

In carrying out the invention a telescopic casing A is preferably provided for the registering mechanism of the instrument, the top of the inner or body section of the case being provided with a glass or crystal 10, the upper portion of the outer section of the case being carried over the edge of the glass or crystal to form substantially a bezel. IVithin the bottom of the said casing, at one side, a shaft is journaled in suitable bearings, and the said shaft extends out beyond the casing, as shown in Fig. 1, andhas secured upon its outer Serial No. 549,171. (No model.)

extremity a spur-wheel 11 of any approved construction. Vithin the casing the shaft 10 is fitted with a worm 12, which worm is made to mesh with a wheel13 secured upon a spindle 14, mounted to revolve centrally within the casing, being carried upward or outward to within a predetermined distance of the crystal 10.

An auxiliary casing B is located within the main casing, the auxiliary casing comprising a bottom plate or partition 15, which is usually secured by passing a pin 16 attached to it through guides 17 secured upon the inner face of the main easing, and opposite the guides 17 a stud 1S or its equivalent is fastened to the main casing, likewise serving as a support for the bottom plate of the auxiliary casing. A cap-plate 19 is made to rest upon the partitionplate 15, and may be secured thereto if desired, it being understood that both of these members of the auxiliary casing are iitted with openings, through which the spindle 14 extends.

The cap 10 of the casing is made to support a dial 20, the dial being raised a predetermined distance above the said cap-plate, as shown in Fig. 2, and the spindle 11 likewise passes through this dial and has secured upon its outer end a hand or pointer 21. This hand or pointer extends over the dial beyond the periphery thereof, and is elevated a predetermined dist-ance above the outer face of the dial, while its outer or free end is bent downward below the edge of the dial, being adapted at a point in the circuit of the dial to engage with the teeth 22 of a spur-wheel 23, which is mounted to turn between the dial and the capplate of the auxiliary casing, the spindle to which the spur-wheel is attached being j ournaled at one end in the cap-plate and being passed through the dial at its 'other end, and has a button 24, or the equivalent thereof, secured to its outer extremity, it being understood that a suitable opening is made in the marginal flange of the dial, as shown in Fig. 2, for the passage of the teeth of the said spur-Wheel. This spur-Wheel has numbers produced circularly upon its upper face, reading from 0 to 9, and an opening 25 is made in the dial, at which one number at a IOO time will be exposed, as shown in Fig. l. A second spur-wheel 26 is likewise mounted to revolve between the dial and the cap-plate of the inner casing, and this latter spur-wheel is also provided with numbers on its outer face reading from 0 to 9, and is iitted with a button 27, whereby it may be revolved from the outer face of the dial. The numbers of the second spur-wheel appear at the opening 2S made in the dial, as shown in Fig. l, and arranged adjacent to the opening 25, so that the numbers at these two openings may be read together.

The second spur-wheel 26 is rotated the distance of one tooth at each complete revolution of the spur-wheel 23, by means of a pin 29 on the spur-wheel 23, which will engage with a tooth on the spur-wheel 2G, one wheel being madev to overlap the other to a predetermined extent. The dial itself is marked at the margin with a scale representing fractions of a mile, and when the pointer has made the complete circuit of the dial the vehicle will have traveled a mile, and the pointer will thereupon strike a tooth 22 of the units spurwheel 23 and cause the figure 1, for eX- ample, to appear at the opening 25; and when ten miles have been traveled by the vehicle the 'units-wheel will have made a complete revolution, and its pin 29 will then strike a tooth of the tens spur-wheel 2G, and will cause the figure l to appear at the opening 2S, a O appearing at the opening 25, recording ten miles, while the fractions of a mile may be read from the face of the dial. The units and the tens wheels 23 and 26 are adapted to register the number oi' miles traveled by the Vehicle duringa specified time-as, for eX- ample--one day; and when the vehicle is started the next day the wheels 23 and 26 are turned through the medium of their buttons to bring the ciphers at the openings 25 and 2S in the dial.

Three or more disks, usually three, are employed to register the aggregate number of miles traveled by the vehicle in the season, for example. These disks are graduated in size and are contained within the auxiliary casing B. They are loosely mounted on the spindle 14, and the larger and innermost or lower disk is designated as 30, the next as 3l and the next as 32. Preferably partitions 33 are employed to support the several disks, but these partitions are of considerably less diameter than the diameter of the disks.

Eachof the disks is provided upon its upper face near its margin with numbers circularly arranged and reading from O7 to 9, and a number from each disk is adapted to appear at the elongated opening made in the dial, as shown in Fig. l.

A dog 35 is pivoted upon the main spindle ll below the auxiliary casing B, being provided withapin 36, whichis normallypressed against the under face of the bottom partition l5 of the inner Casin g by means of a spring 37,

as shown in Fig. 2, and at one point in the rcvolution of the dog it is adapted to engage with a lip or stud 37, projected downward from the bottom partition of the inner casing, as shown in Figs. 2 and 5, the bottom of which stud is more or less inclined.

vAdjacent to the stud 37 a segmental slot 3S is made in the bottom plate or partition oi the inner casing, as is likewise shown in Fig. 5, the said segmental slot being of a predetermined length, and it is in the path of the pin 3G of the dog 35, and as soon as this pin reaches one end of the slot the dog will be engaged by the stud 371L and carried over the edge of the slot, so that it may travel the remaining portion of its circuit in engagement with the plain surface of the said inner casing.

In the bottom face of the lowermost registering-disk 30 nine recesses 39 are made, circularly arranged, and between two of these recesses a slot #l0 is produced in the disk, as shown in Fig. Ll. The next registering-disk 3l is provided with a similar opening and recesses, but the upper and smaller disk 32 (shown in Fig. is provided with ten recesses 4l only. The outer casing is provided with a bracket 42 of any approved construction, enabling it to be attached to the axle of the wheel, and a projection is formed on the hub of the vehicle wheel-which at each revolution of said wheel will strike the spurwheel ll, causing it to revolve a predetermined distance.

The operation of the aggregate registering mechanism is substantially as follows: The disks of the main registering mechanism are set so that the cipher of each will appear at the opening 34, and the dog 35 will be substantially in the position shown in Fig. 5, or at one end of the slot 38 in the inner casing. By the time that the main spindle let has made a complete revolution, which will be when one mile has been covered by the vehicle, the pin 3G on the dog will enter the slot 38 in the inner easing and be received in any one of the recesses 39 in the lower disk 30, the recess being near one end of the slot 410 in said disk, and the dog in traveling farther will carry with it the lower disk, moving it a sufcient distance to bring the figure l 7 in registry with the opening 3% in the dial, and at that time the dog will be received by the stud 37 on the easing and carried over the end portion of the slot 38. rlhis operation of moving the lower disk will be carried on in this manner until ten miles have been covered, and

at that time the slot 40 in the units-disk will receive the pin from the dog, and the pin in going out through this slotwill enter one of the recesses in the disk registering tens and will turn that disk one point simultaneously with bringing the O of the units-disk at the opening 3at,thus showing at this opening a record of ten miles. Vhen one hundred miles have been covered, the slot in the tens-disk 3l IOC IIO

IIS

Will be in registry with the corresponding slot in the units-disk, enabling the pin on the dog to pass through both disks and enter one of the recesses Lil in the upper or hundreds disk 32, moving that disk a sufficient distance to bring the numeral l at the opening 3-1, and at the same time the tens-disk Will have been moved a sufiicient distance to cause the 0 to appear at said opening, making the register read 100, and as there are ten recesses in the disk registering hundreds of miles the capacity of the instrument as illustrated Will be that of registering a thousand miles; but it will be understood that the registering capacity of the instrument may be increased or decreased as in practice maybe found desir'- able.

This instrument is exceedingly simple, durable and economic in its construction and accurate in its register, and it enables a person to obtain not only the aggregate number of miles traveled in a specified time, but also the number of miles traveled in a speciiied or shorter length oi' time, one register in no manner interfering with thc other. Y

Having thus described my invention, I claim as neiv and desire t-o secure by Letters Patent- 1. In a cyclometer, a series of recording disks all loosely mounted on a spindle, means comprising a worm and Worm Wheel from which the disk spindle is extended for actuating the disks from the Wheel of the vehicle, a dial, a pointer mounted on said spindle and adapted to travel over the dial, and registering Wheels independent of the disks and operated bythe movement of the said pointer, as and for the purpose specified.
