TO WHOM IT MAY CONCERN:

Be it knownthat we, MILTON W. NnsMrrn and Geenen' W. NEs'MIrH, of Metamora, in the county of Woodford, andA State of Illinois, have invented certain new and-'useful Improvements in Grain-Registers', and we dry hereby declare that thefollowi'ng is a full, clear, and exac'tdescription thereof, reference being had'to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur. l

To enable others skilled in the art -toeonstruct and use our-invention, we will proceed to describe it.

Our invention consists in a novel construction of an apparatus for registering with accuracy and certainty, the quantity of grain measured, as it is delivered from threshingmachincs, or from bins or 'other places where it may be stored. In the vdrawings-'fv Figure 1 is a perspective view-of theapparatus complete.

Figures 2, 3, and 4, are views oi'. the registering-mechanism detached, for the purpose of showing its con struction more in detail. A l A In the grain-growing regions ofthe country, it is. customary to employ the proprietors of threshing-machines to thresh th'c grain at a specified price per bushel; .and it is desirable, both for -the owner of the grain and the thresher, 4to have lsome certain and acenratc'means of ascertaining the -exact quantity of the grain threshed, and also to provide means for preventing either accidental or intentional errors in the registrationof the amount or quantity. To accomplish these purposes is the objectief our invention, which is 'as follows:

Weprovide a box,`A, in'which we secure a registering or counting-mechanism, enclosed in a suitable ease or box, B, provided with'a cover, C, to exclude grain, dust, or other substances thatmight interfere with the operation of the mechanism, this coverbeing -provided 'with 'a small window, I, through which the numbers on the registering-wheels may be seenwhen the box B is closed, these parts being shown in fig. 1.

The registering-mechanism consists of a serios of wheels, v, having numbers arranged in regular order en their peripheries, in the usualmanner. The outer one ofthe series of wheels v, is provided also with a series of ratchet-teeth, m', double in number to the number of igures on said Wheel, and both this and all succeeding wheels of' the series, except the last one, have,- projecting from their opposite sid'e, a pin, x, as shown in lig. 2, these wheels v all being mounted side by side, upon acommenjournal,` onv which they turn loosely, so that each may be moved independent of the others. Upon a counter-shaft or journal, c, we mount a corresponding series ofwlieels, u, which latter lare provided, on their periphery, with two sets of cogs, one set Acorresponding in number andsize with the cogs m, secured to each of the wheels o, except the'rst, and the other set being only one-third as numerous, and disposed' at regular intervals, as represented in'iig. 4. These wheels Mare so placed that their first or lmore numerous series of cogs will engage with the cogs 'm on wheels v, and thus turn the latter whenever vthey themselves are moved, the wheels u being moved only when the pins x of wheels v are brought'around in contact with the cogs s, and-which can occur but once at each revolution of the wheels v, a springpawl, h, being arranged to engage with the cogsof wheels u, and prevent their being accidentally turned, this arrangement of. theparts being more clearly shown in iig. LZ. I

' -For operating Athese -Wheels-we provide alevcr, L, which 'is pivoted bya-journal, T, to the case B, in such u manner as to have the lever L protrude from the side of the case, as shown in figs. 1 and 2, for a purpose to he hereinafter explained. An arm, d, protrudcs from the opposite side of the journal T, from the end of which extends a rod,j`, connecting it with an, arm,'g, of a rock-shaft, G, as shown more clearly iu iig. 3. To this rock-shai`t we secure a pawl, consisting of a frame or plates, P, between which is pivoteda dog, t, at e, this dog t being provided withlan arm, u', whichis arranged to strike against a' pin or stop, 1*, by` which its forward movement on its pivote is limited, a spring, n, being arrangedv to press against the rear or upper side of the dog t, and keep it pressed forward, l'except when pushedback, as' hereinafter explained. This pawl is so located,

vthat the dog t will engage with the ratchet-teeth m lon the rst wheel'v, s as to movel the wheel one notch every time the le'vcr L is moved forward, there beings. spring, p, applied to the journal T, by which means the lever is thrown back as soon as released, after being operated, the dog t yielding, s o as to let its 'end pass by'one of the ratchet-tceth m', as the leverL resumes its' position. -A springpawl, o, is so arranged as to engage with the rntchetteeth m','and thus prevent the wheel v from movingbackwnrd by any means.

With the mechanism thusconstructed and arranged, it will be seen that when the lever L is operated twice, the iirst wheel v will be moved a distance equal to that at which the numbers on its periphery are placed from each other, this arrangement being adopted for the reason that while the grain is measured in a half-bushel measure, it is desired to register the number of bushels only. When'the wheel has thus been moved until the number nine is under the window I, the pin :r on said wheel will havcpassed around, so as to be in contact with one of the teeth s on the first wheel and 'as the wheel v is-moved so as to bring the next ligure under the'window, the wheel u will be moved with it, and as this latter moves, it'will also carry with it-thcJiext dial-wheelfv the distance of one-figure, after which the pin a: will b ev disengaged from the cog s, and pass on, leaving the other wheels remaining stationary until the pin x shall have passed entirely around, when it will repeat the operation, thus at cach revolution moving the adjoining dial-wheel one interval or` ligure. This operation is continued until the Asecond dial-wheel will have made one revolution, when its pin x will, in the same manner, move the next dial-wheel one interval, and soon to any required extent, the drawing represcntingbut three dial-wheels, which, with -the ten numbers on each, 'will register' as high as nine hundred and ninety-nine, which is -as much as can ever be requircd'iri any one day by a threshing-machine. By adding to the series of wheels, the capacity of' the machine may -be increased to any desired extent.

Having t'hus constructed our registering-apparatus, and secured it in its case, B, we secure the whole in a box, A, which box we make of such a. size as to permittwo half-bushel measures, H, to be placed and easily moved about therein, as representedin fig. 1. In the centre of the box A, we place a post, D, at such a distance from the case B that the measure H-can .be passed between the post and the case, and in so doing strike against the protruding-.part of" the lever L,.and therebyoperate the register.

' The operation' is as follows: The box is tobe placed under the delivery-spout of the thresher, in such a position that the cleaned grain may be received into one of the empty measures placed behind the lever L, as represented in g. 1. When the measure is full, it is drawn forward between the post D and the case B, striking thellever L as it passes it, the otherv measure H being atthe same time placedv under the spout as the-full one is removed.4 The full one is emptied by the attendant while the other is being filled, and thus the process is continued, the registeringLapparatus thus indicating with accuracy the number of bushels measured. It is obvious that, if preferred, the spout -maydeliver the grain' in to the measure on the opposite side of the lever L, the latter,in that case,ubeing operatedby the empty measure' behind, as it is drawn forward to take the place of the full-one. y It is also obvious that instead of. the box being made of such a size, with the post D, to guide the measure in its movement,vthe box A may be made of half the width, and the measures, as they are drawn forwariL-be lifted outandvthen replaced, .one behind the other, thus accomplishing the same object, theessential requisite being that the lever L shall be operatedbyeac'h of the measures as-they are moved. Anysurplus grain that may chance to fall fromthe spout, and not be caught in the measures, or that may be removed from the measure, in case it is allowed, by.accident,'to become too full, will be caught in the box'A, from which it may be removed andmeasured-atvany time. The case B should be provided withea lock, so that it cannot be opened, or the mechanism interfered with by others; and there is apin, b, arranged to fit Ainto a hole, o', in front of the leverL, by which thelatter may be locked, and preventedfrom' beingimoved when the machine is left, as will be necessary during meal times, nights, and other` times when theA work ceases This pin b is shown in iig. 1, attached by a cord, and inserted, for convenience, in a hole in the end of the case, where it is vkept when not required to lock the leverL. It is obvious that our apparatus'may beusedwith equal facility for measuring and registering grain taken 'from bins, storehouses, and all similarlplaces, especially where the grain is delivered 'through `a spout. i I

By these meansvwe provide an apparatus that is especially adapted: to the wants of the community, that is reliable, and being portable, and detached from `the threshing-machine, can be used with equal facility with any style or make of machine, and also independent of threshingmachines. for measuring grain elsewhere.

Having thus described our invention, what we claim, is

1. A. grain-measuring apparatusyconstructed substantially as described, and provided with a registeringdevice operated by a lever, so arranged that by drawing the measure past it in one direction` theregister will be operated substantially as-described.

n 2. 'lheregistering-devic'e, consisting of the dial-wheels v, provided with the pins ir, and having the gearwheels 'm attached,-in combination with the donblewheel u, when said parts are arranged as described, and operated by the pawl P, as and for the vpurpose set forth. Y

8. The pawl P, having the dog t, with the stop r and spring n, all arranged substantially as described.

4. The combination of the registering-device, the pawl P, and the leverL, all arranged to operate as and for the purpose set forth.
