Application filed September 6, 1905. Serial No. 277,212.

exact description.

The purpose of the invention is to provide an odometer of very simple, durable, and economic construction ,i wherein a series of registering-disks and a series of recording-disks are mounted upon the same vcarrying-shafts, the recording-disks being so arranged that they will show the aggregate amount of miles traveled during a number of trips-for example, thc registering-disks being adapted'to show the number of miles made during each' trip, and the arrangement of the latter disks is such that all of them may be quickly andI conveniently turned back to zero at any time by turning the carrying-shaft and without changing the position of the recording-disks.

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 tothe accompanying drawings, forming a part of this specifica; tion, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of the improved device. Fi 2 is a vertical longitudinal section throug the casing of the device and a artial vertical Section and side elevation of? the interior mechanism. Fig. 3 is a vertical transverse section taken practically on the line 3 3 of Fig. 2. Fig. 4 is a side elevation of a recordin -disk and a section of the carrying-shaft, t e section being taken substantially on the line 4 4 of Fig. 2. Fig. 5 is a detail sectional view of a portion of one of the disks, a plan view of the actuating-pin' for the disk, and a transverse section through the spring-arm carrying the pin. Fig. 6 is a section taken substantially on the line 6 vof Fig. 2, the section being through a spacingcollar of a registering-disk and the carryingshaft, the shifting sleeve for the disk being shown in end view. Fig. 7 is a vertical transverse section taken practically on the line 7 7 of Fig. 2; and Fig. 8 is a transverse section through the actuating spring-arm `for a disk,

`ing an e arged upper end 16a.

either registering or recording, the section eing vtaken practically on the line 8 8 of Arepresents a box-casing having suitable lugs 1() for attachment to a vehicle and a glass pane 1 1 at the top, through which a plate 12 is visible, having two series of openings 13 and 13"L therein, a series being at each side of the center of the plate, as shown in Fig. 2.

vAt the central longitudinal portion of the casing A a bar 14 is located near the bottom of the said casing, which bar .extends from end to end of the casing and is attached thereto, being provided at its ends with upwardlyextendin arms 15 and a central arm 16, hav- A shaft Bis journaled in the said arms 15 and 16, having endaswell as rotary movement. The righthand end of the shaft B extends out through an opening 17 in the right-hand side of the casing, as is shown in Fig. 2, and is secured vto a knob 18, 'having a chamber 19 in its inner face, in which chamber' a spring 20 is located, coiled around the carrying-shaft B and having 'bearing against the right-hand arm 15 of the bar 14, as is also shown in Fig. 2.

A series of registering-disks C is loosely mounted on the shaft B, one below each opening 13 and the said disks C are provided with peri heral figures reading from 0 to 9, ine usive. Each disk C is also provided with a central bore 21, of sufficient size to receive and turn loosely around a sleeve 22, as is shown in Fig. 2, and the sleeves 22 of all of the disks are in frictional engagement with the carrying-shaft B. Each sleeve 22 is provided with a finger 23 at its in Fig. 2,) the rear pins 24 hold the sleeves 22 1 in such position that their fingers 23 are rcmoved some distance from the outer side faces of the disks C, as is also shown inKFig. 2. The disks C are spaced from each other by collars 25, loosely mounted upon thev carrying-shaft B, which collars are suliiciently large-at their inner end portions to permit the fingers 23 ofthe sleeves 22 to frceiy turn therein, and a simple collar 26 spaces the innermost disk C lfrom the central arln 16.

IOC

At the outer side face of each registeringdisk C a series of openin s 27 is made, corresponding in number to t e number of figures upon the periphery of a disk, an opening 27 being immediately below each gure upon a disk, andone side of each opening is provided With an-inclined outer wall portion 27'?, as illustrated inFi s. 4"and 5, s aid inclination being provided or a purpose to be hereinafter set forth. I

A pin 28 is made to reject from the-outer face of each disk C aciiacent to its bore 21, the said pins being in the path of thefin ers 23 of thel sleeves 22 when the shaft Bis pus ed inward, as when said shaft is carried inward' the outer pins 24a on the shaft will carry the sleeves 22 in the same direction, so that as the shaft B is turned while at its inner position the sleeves 22 will be turned also, `and the lingers 23 of the sleeves upon strikin the pins 28 will simultaneouslyT turn all o the disks C, and said disks C are thus turned when they are to be brought to their initial position, presenting zero at the openings 13, as will be hereinafter more particularly described.

A s rin latch-arm C is located at the inner si e o each disk C, as is shown in Figs. 2 and 7. Each spring latch-arm consists of a ring-like-body 29, sufficiently large to loosely receive a spacing-collar 25, which body has a head-piece 30 integral therewith secured to the disk to which the latch belongs and a foot-section 31, that extends to the edge of the disk, as is particularly shown in Fig. 7. The foot-section 31 of a s rin -latch has a s'tud 32 extending inwardtiiere om' or in direction ofthe opposing disk, and the studs on the latch-arms of one disk are adapted to enter the openings 27 in an opposing disk to turn the same at a proper time, and atA the outer end of the foot-section 31 of each spring-latch arm C the foot is bent upon itself so as to extend out at an inclination in direction of an op osing disk C, forming at the foot-section ofp each latch-arm C an inclined offset toe 33, as is shown in Figs. 2, 5, 7, and 8. After a disk C has made one revolution the foot-section of its latchwill enga e with Aa spur 34, extending u ward from t e bar 14, a spur bein provlde for each latch, and as the toe 33 o? the latch engages a spur 34 the foot of the latch will be sprung outward, causing the spur on the latch to enter an opening 27 in the opposing disk to turn the same one figure, and as soon as the foot of the spring-latch has passed the spur with which it engages the sald latch, owing to its resiliency, will spring back against the disk,

assuming its normal position and Withdrawing the stud from engagement with the disk which it had just moved. The bevel 27* in the walls of the opening 27 'facilitates the quick entry of the stud 32 into said opening.

A ratchet-wheel C2 is loosely mounted upon the ri t-hand end portion of the carryingshaft, separated from the first registeringdisk C by a collar 35, corresponding to the collars 25, and in connection with the ratchet Cz a spring latch-arm C is employed of the same construction as those which have been described. The said spring latch-arm for the ratchet-wheel is adapted to give movement at the proper time to the initial or units disk C by reason of the stud 32 of the said latch-arm entering an opening 27 in the said rst disk C, as is shown in Fi 2. The latcharm for the ratchet-wheel 2 is attached to .the offset36 from the periphery of the wheel,

.the spurs 34, heretofore mentioned, being carried by the same bar 14. The ratchetwheel Cz is provided with a pawl 37, which prevents the Wheel slipping in the wrong direction, said pawl being mounted on the right-hand arm`15 of the spur-carrying bar 14.

A counter-shaft 38 is mounted in suitable bearings in the casin A below and to one side of the bar 14, an at the right-hand end of the'counter-shaft 38 an eccentric 39 is secured to said shaft, as is shown best in Fig. 3, which eccentric receives a collar 40 of a dog 41, which engages with the teeth of the ratchet-wheel Cz to turn said wheel at redetermined intervals. The dog 41 may e attached to the eccentric 39 in any approved manner-as, for example, the eccentric may be provided with a peripheral groove, and a set-screw 42 may be passed through the collar into said roove, as is shown in Fig. 3. A s ring 43 hods the dog down to its work.

he counter-shaft 38 is rovided with a worm-wheel 44, which mes es with a worm 45 upon a shaft 46, and this shaft is led out from the casing throughs. suitable bearing to a connection with the axle of the vehicle or other factor from which speed and power is to be taken.

It will be observed that as the ratchetwheel C2 is turned to bring the post 32 of its latch-arm C opposite an opening 27 inthe initial registering-disk C the said ost will enter said opening and the disk Wil turn With the ratchet-Wheel until the foot portion of the latch-arm C has passed its spur 34., and after the rst disk C has'made one revolution the spur of its latch-arm C will beforced by reason of the foot of the latch-arm riding on its spur 34 into the opening 27 in the next recording-disk to turn it in the same manner as has been described with reference tothefirst disk C, and this operation is re cated until all of the disks have been turne toindicate at the openings 13 in the plate'12 the number of miles traveled-as, for example, 199 as shown in Fig. l-and the latch-arms C', as shown in Fig. 2, and the first, second, and third disks C occupy. such positions relative ICD simply pushing in the shaft to their controlling-spurs on the bar 14 that at the next action ofthe ratchet-wheel C2 the figure on the iirst disk will be changed from 9 to H0, the figure on the s econd'disk from 9 to 0,. and the figure 1 on the third disk will be changed to 2, making the reading atsuch time 200. Supposing the end of the journey to have been reached and it is desired to ca all of the registeringdisks C back to zero, t ls is uickly done by as hasrbeen described, until the ingers'23 of the sleeves 22 are brought in the path of the ins 28 on the disks C, whereupon the said sha t is turned until the foot portions of all of the latcharms C are in enga ement with the rear faces of the other control ing-s urs 341and 34, and

at such time a cipher W' l appear at each of' the openings 13. l

To the left of the casing a series'of recording-disks D are loosely mounted on the shaft B, and each recording-disk has figures on its periphery reading from 0 to 9. On the said shaft B adjacent to the first recording-disk a ratchet-wheel D is loosely mounted, provided wth a latch-arm D2, and each of the recordin disks is likewise rovided with a latch-arm 2, all of said latc -arms Dz being alike in 4construction to the construction of the latch-arms C', heretofore mentioned. The ratchet-wheel D is operated through the medium of a dog 47, corresponding l'to the dog 41 for the registering-disks C, and this dog 47 is mounted upon an eccentric 48 at` the inner end of the line-shaft 38, as is shown in Fig. 2, the eccentric 48 being a duplicate of the eccentric 39. Each recording-disk D is (provided with a series of openings 49 in its si e, correspondin to the openings 27 in the registering-disks A recording-disk D is located below each o ening of the series 13 in the plate 12, so that the figures on said disks may be read at said openlngs, and the operation of the recording-disks is identical with the operation of the registering-disks, the foot portion of each spring latch-arm D2 being provided with a controlling-spur 50, carried by the bar 14, as is illustrated in Fig. 2. The disks are spaced one from the other, preferably by means of hubs 51, located at one side face. The recording disks are ada ted to show the aggregate of miles travele in a number of trips, while the registering-disks are adapted to record simply the number of miles traveled at each trip. Consequently it is not necessary to provide Athe means shown in connection with the registring-disks to turn the recording-disks back; but such means may be employed or other means may be utilized for bringing the recording-disks. to .zero when desired. As shown, it will be observed that the o erationl of the shaft B to set the registeringisks has 3 0 1ilifluence whatsoever upon the recording- `Patent- Having thus described my invention, I claim as new and desire-to secure by Letters 1.
