iMPROVENlENT lN CASE-S FOR ODOMETERS.

The Schedule referred to in than Letters Patent and making put of the lame.

To all whom. it may concern:

Be it known that we, JACOB 1).Snrrnt. and (Jrnus B. ALsovun, both .of Easton, county of Northampton,

. State of Pennsylvania, have invented certain new and useful Improvements in Odometers, of which the following is a full, clear, and exact-description, reference being had to the accompanying drawing making part of this specification, in'which Figure l is a perspective view of our improved odometer, showing it as being applied to a wagouaxle;

Figure 2 is an end view with a portion of the. shell broken away; and v Figure 3 is a plan or top view with the upper half of the shell removed to show the gearing.

Similar letters of reference denote corresponding parts in all the figures.

Iirthc drawing- A represents an axle of a wagon;

B, the inner end of the hub of the wheel; and

I), aspur or stud projecting from the 'v'BltlGtLlfitC-G of the hub. v

. b'isa groove in the rim of the shell or case, adapted to receive a suitable elastic. packing to exclude dust.

O O is the shell or case, of irregular form, substantiallyas shown-iufig. 1.- It is divided into two parts, the upper part 0 extending down to a line with the lower side of the axle on one side, as shown in fig. 1, while 011 the other side the bottom part 0 extends up nearly or quite to the upper side of the axle. This construction has been adopted on account of convenience in closing the parts around the'axle, thetwo parts being hinged together at O.

The upper part 0' is much the larger, and contains all of the working parts,'the lower part0 serving to assist in securing it to the axle, to exclude dirt, and to preventthe' machine from being disturbed either through accident or design.

The machine is secured to the axle as follows:

The lower part 0 is constructed with a channel or recess, indicated by dotted lines 0 c c in fig. 2, into 'which the axle fits, and is expanded upon its outer edge, that is, the edge farthest from the hinges, forming an car, 0, which projeets abovc and outside of the lower edge of the nppcr part (i, as is plainly shown in fig. 1, and is perforated at c", fig. 2, for the reception ofa clamp-screw, D, said pertbration being provided with a. screw-tlmaad into which the clampscrew fits, and the upper part .0 is also perforated at a point which corresponds to that in the lower part when the shell is closed.-

Al'ter, the machine has been placed upon the axle, as in fig. 1, the clamp-screw is inserted far enough to impinge upon said axle, as in fig. 2 by which means the two parts of the shell are'sccured to each other and to the axle, as will be readily understood without further explanation.

Upon the upper face of the machine tnere 15 a dialchamber formed by a raised rim or flange, and covered by a hinged or pivoted lid, E, which may, when pro-- l'erred, be provided with a glass plate through which the position of the pointers 13 E may be seen.

The lid 1' is shown as beingsecurcd to a perforated lug or staple,-E, by means ol a small-padlock, 1 the hasp of which passes through staple E an car a on the lid, and the socket of a wrench, D".

The shank of this wrench fits into holes (I in the head of the clam p-screw, and serves the double purpose of tightening the screw and of looking it in place to prevent accidental displacement ,Thus it is apparent that, by this combination and arrangement of devices, the lock F is made to secure the lid E and the clampscrewi) from being moved, except by first removing the lock.

G is a' star-wheel, having any suitable number of arms 9. It is mounted upon a short vertical shaft, G, and is actuated by the spur I) on hub 13, being moved forward one arm at each revolution of the carriage-wheel.

The upper end of shaft G is supported in upper shell C, while its lower end rests ina step or hearing in .a bridge-plate, 11', shown partly in full lines and partly in dotted lines in fig. 3.

Bridge-plate H is rigidly attached to upper shell 0 by any desired number of pins h, and forms, in connection with said shell, the sole supportfor the registering mechanism.

G is a spur-pinion, attached to or cast with starwhcel G, and gears with a spur-whecl, I, which, together with a worm or screw, 1', are mounted upon vertical shaft 2', see fig. 3.

The worm I takes into and drives a worm-wheel, K, (see fig. 2,) which is rigidly secured to a horizontal shaft, K, (see fig. 3,) which carries on its opposite end a sci-cw, L, which, in turn, drives a worm-wheel, L, mounted upon a vertical shaft, and carrying with it a spur-pinion, L.

Worm-wheel L is shown in 3, but cannot be shown in fig. 2 because it is in the same horizontal plane with worm 1', and directly behind it when the parts are in the position represented in this figure.

Iinion If gears with pinion M, mounted rigidly on the same shaft with pinion N, this latter gearing with and driving the spur-wheel N. Pinion N cannot be shown in fig. 2 except in dotted lines, because it is in the same horizontal plane with the spur-wheel I, and right behind it; in fact wheel N is shown partly in dotted lines in thisfigure.

The shafts l and a project through the top of the upper shell 0 into the dial-chamber above described,

and carry on their projecting ends pointers E E, which sweep over 'circles' of figures arranged in the manner customary inthis class of ineasurin'g-instruments, and need not, therefore, be further described.

0 is a tongue-spring, one end'of which is attached to the shell, while the free end rests upon the face of the star-wheel G for the purpose of retaining said wheel in the position to which it has been moved, will hereinafter be explained.

In applying our register to a wagon or carriage, care should be taken that one of the arms or fingers of the star-wheel point pretty nearly directly at a right angle to the vertical face of the wheel-hub, substantially as represented in fig. 2, in order that, whichever way'the vehicle he moved, the star-wheel shall be in proper position to be actuated by thespur b, when the mechanism may be secured to the axle by means of clampscrew D, as has already been explained.

At each forward revolution of the carriage-wheel, star-wheel G, pinion G, and spur-wheel I, will be moved forward one cog, and one complete revolution of wheel I and screw 1' will move wheel K forward one cog, and so on through the entire train of geariugft-h'e pointers E E indicating on the dials the distance traveled, the gears I\ and N acting as multiplying gears, through which the pointer E, carried by wheel M and shaft m, is made to revolve ten times while pointer 15"- revolves once. 'lhus pointer E may be made to indicate single miles and pointer E ten miles by moving from one figure to another on the dial.

it will be seen in fig. 1 that the eye at one end of the wrench D is adapted to fit the .nuts which secure the pointers on the ends of their respective shafts.

By employing this peculiar form of shell, hinged together in this manner, we are enabled to attach our operating mechanism to the upper portion, thus protccting them entirely from the rain,:ind we can-secure the two parts of the shell to each other and to the axle by a single clamp-screw.

\Ve also, by our construction and arrangement of devices, provide against the register being removed from its proper place on the axle, and against the indicator being tampered with by the use of a single lock.

The dial-plate now attached to the machine is adapted to be used with a wheel of fifty-one inches diameter, but it is evident that provision maybe made for applying the device to carriages having different-sized wheels by having a number of dials spaced correspondhig to the wheels, and which can be readily applied by taking off the pointers. In case this is done, it would be well to indicate on the dial the sized wheel with which it is to be used.

\Vhen desired, pieces of rubber or leather may be interposed between the shell and the axle to prevent the latter from being bruised.

It will be readily seen that the pin 11, which DIOJCCtS radially from the center of the hub, will, by engaging with the inner side of the rim of the shell 0 0, always be l ept in proper working relation to the star-wheel, so that the wheel of the carriage cannot revolve without actuating the registering mechanism.

Having nowdescribcd our, invention,

What-we claim as new, and desire to secure by Letters Patent, is-- ]-..In an odometer, the shell composed of two parts O G, hinged and secured to each other and to the axle by the clamp-screw D, substantially as set forth.

2. The-c0mbination of the hinged lid E, stationary l 1g E, wrench l) nut D, and look I substantially as and for the purpose set forth.
