Application tiled October 18, 1890. Serial No. 353,587. (No model.)

To @ZZ t/:tont it nmy/ concern:

Beit known that i, GEORGE CORNER France, a citizen of the United States, residing at Lewistown, in the county of Fulton and State of Illinois, have invented a new and useful Grain- ScaleZ otl which the following isaspeciiication.

This invention relates to improvements in grain-weighing machines, the object of the same being te provide a machine of this characier possessing improvements over others ot' a similar nature heretofore made.

To this end the invention consists of the details of construction hereinafter more fully described and claimed, and as illustrated in the drawings, in which- Figure l is a perspective view of this machine complete. Fig. 2 is a rear elevation. Fig. 3 is a side elevation showing the door of one of the boxes as open in full lines and as closed in dotted lines. Fig. 4 is a central transverse vertical section of the machine. Fig. 5 is an elevation of the registcrl preferably employ, with the outer side of the casing removed. Fig. G is adetail view of the lower end of the weighing-beam.

Referring to the said drawings, A is the casing oi this machine, within which is the divider B, arranged across the center thereof. Above this divider on pivots C is mounted an oscillating hopperD, which is of funn el shape, as shown, and into whose upper end projects the feed-pipe E, leading from the elevator or other source of grain-supply.

Upon the rear of the hopper is a cam il, as best seen in Fig. 2, and a roller G upon the upper end of an arm ll engages this cam and throws the hopper so that its lower end will deliver to one or the other side of the divider B, as will be clearly understood by persons familiar with this class of machines. The arm il is keyed upon a spindle I, extending through the casing A from the rear to the front thereof, and keyed to the front end of this spindle is the scale-beam J, rising upwardly and provided with the shifting weight K, adapted to be adjusted upon the sealebeani and held in position by means oi' the set-screw L.

Pivoted to the scale-beam J at points M are two levers N, whose lower ends are provided l with knife-edged bearings O and whose up per ends are reduced.

l is a catch having the slot S', sliding over a stud Q on the scale-beam, and having a setscrew i., taking loosely through a slot S in said beam, whereby the catch may be raised and lowered and held in either position. The lower face of this catch is curved and is provided with four notches T, one pair being located nearer the center of the scale-beam than the other pair, and in these notches the reduced upper ends of thelevers N are adapted to be seated, for a purpose to be described hereinafter.

U 'U are boxes whose bottoms incline inwardly and forwardly, and which are provided with eyes r', rising from their inner side walls, which embrace and rest upon the knifeedged bearings O, above mentioned, by which means the boxes are pivotally supported from the levers N, and \r T are links which are pivoted at one end to the base of the easing and at the other end to the bottom of the boxes, their function being' to prevent the latter from swinging and thus interfering with the operation ot' the machine. The front XV ot' each box is pivoted or hinged at X along the upper corner thereof and extends above its pivot, Fig. 3, and pivotally connected to the upper end oi' this front is a toggle-lever Y, whose rear arm is pivoted at Z to the box and extends slightly beyond and in rear of such pivot.

Z is a branch arm rising from the toggle Y near its pivot and having an upright bend or portion Z2, as shown. Rigidly connected at right angles to the arm Il is a horizontal arm o, carrying rollers b at its extremities, which rollers operate between the arms Z and Z2.

llfith the above construction ot' parts when the grainis flowing down the feed-pipe E and the hopper D is turned to one side one box. U is being iilled. As soon as it is Iilled to the desired extent its weight overcomes the force of weight lx'. and throws the sealebeam J over to the other side. This motion turns the spindle l, moves the arm il, and throws the roller G the length of the cam F, therebyT moving the hopper D upon its pivots C and TOO shifting the flowing stream of grain across the divider B into the other box U. At the same time the horizontal arm a is moved lto its opposite position, and this motion lowers the roller b, engaging the toggle Yof the box which has just been filled, opens the front W thereof, and delivers the grain into a chute c, whence it may be conveyed to a wagon or to any suitable and desirable point. The front d of this chute rises to a considerable distance above the bottom thereof in order to prevent the grain flowing out of the boxes from overflowing from the chute, and the entire chute is pivoted at c, so that it may be shifted from side to side to deliver the grain at either side of the separator upon which my improved machine may be placed. The scale-beam weighs half-bushels of grain at each draft, the same being regulated according to the weight of that much bulk of the grain being measured. The same weight may be used on the scale-beam and without adjustment by adjusting the pivots O O, on which the two boxes are suspended-that is to say, when the reduced upper ends of the levers N are in the innermost notches T sixteen pounds of oats will tip the beam, the same as will thirty pounds of wheat move it when said reduced ends are in the outer notches; and as sixteen pounds of oats or thirty pounds of wheat make a half-bushel it will be obvious that this adjustment of the fulcrum of the scale will cause the latter to measure out half-bushels of oats or wheat, and no adjustment of the counterbalancingweight will be necessary.

Referring now to Fig. 5, which illustrates the register I preferably employ for indicating how much grain has been passed through my machine, 1, 2, and 3 are shafts carrying, respectively, disks 4, 5, and 6, each marked with the ten digits, and the shaft 2 arranged below the other shafts, as seen, the disks, however, being so arranged that the digits will stand in proper position to indicate a number of three figures. Pivoted to the arm H is a pawl 7, having marked thereon the fraction 5, and the tip of this pawl engages a ratchet 8, keyed upon the shaft 1. At every movement of the arm ci in one direction the fracl tion is exposed through the face-plate 9 of the register, and when the pawl moves in the other direction the fraction is carried out of sight and the ratchet 8 and disk 4are turned one space, thus raisin g by one the number indicated. Upon the shaft 1 is a disk 10, having a single tooth 11 on one face thereof and a notch 12 in its edge in rear of said tooth, and on the shaft 2 is a gear-wheel13, whose teeth 14 rest upon the edge of the disk 10, but whose alternate teeth 15 are of half-length, so as to pass by said disk, as will be understood. When ten numbers have been exposed by the disk 4, the single tooth 11 strikes one of the half-teeth 15, and at the same time the notch 12 comes beneath one of the full teeth 14. As the disk 4 turns to 0, at its next movement the tooth 11, engaging the halftooth 15, causes the shaft 2 t-o turn land to.ex pose one higher figure in the next opening through the face-plate. In the act of turning the notch 12 engages the full tooth 14 and carries the disk 13 around until the next t'wo full teeth 14 rest against the edge of vthe disk 10, when the gear 13 willbe locked in this p0.- sition, because its full teeth rest against the edge of the disk 10, and it cannot move until the disk makes another complete revolution,y

again bringing the notch 12 opposite one of the teeth. Although I have not illustrated it, it will be understood that the shafts 2 and are connected in a similar mannerin order to cause the register to indicate hundreds, and, if desired, other shafts can' be added,in.creasing the capacity of the register almost indefinitel y. I prefer to apply this register in connection with my improved grain-weighii'ig device, although I make no claim thereto in the present application. Y What is claimed as new is 1. In a grain-WeighingA machine, the combination, with the pivoted funnel-shaped hopper and the divider below the hopper, of the scale-beam having an adjustable weight, the boxes pivotally supported thereby at either side of said divider, the vertical arm mounted on the supporting-shaft of said beam and carrying a roller at its'upper end, and alcam on the hopper adapted to be struck by said roller when the scale-beam moves, as set forth.

2. In a grain-Weighing machine, the coinbination, with the scale-beam mounted on a pivot, the pivoted hopper, and connections be- TOO tween said beam and hopper for moving the latter on its pivots, of the boxes pivotally supported by said scale-beam and having hingedv fronts, toggle-levers pivotally connected at one end to said fronts and near their rear ends to said boxes and having upwardly-extending arms at their rear end, a horizontal arm keyed to the pivotal shaft of said scale-beam, and rollers on the extremities thereof, each engaging between the rear en'd and the upwardlyextending arm of one of said toggle-levers, as and for the purpose set forth.

3. In a grain-weighing machine, the com bination, with the pivoted scale-beam, levers pivoted thereto near its supporting-pivot and provided with knife-edged bearings at their lower ends, a catch sliding longitudinally on said beam and having. notches engaging the upper ends of said levers, and a means for locking said catch, of boxes mounted upon said knife-edged bearings, a pivoted hopper, and connections between the scale-beam and hopper for moving the latter on its pivots, as and for the purpose set forth.

4. In a grain-weighing machine, the combination, with the pivoted scale-beam, an adjustable weight thereon, levers pivoted to said scale-beam near its supp orting-pivot and having reduced Vupper ends, knife-edged bearings 'at the lower ends of said levers, a slotted catch sliding longitudinally on said beam and hav- `upon said knife-edged bearings, linlcs pivot ing inner and outer pairs of .notches engag l ing said reduced Vends, a pin in the beam loosely engaging the slot in the catch, and a l set-screw passing through a slot in the beam and taking into the eateh, of boxes mounted ally Connecting said boxes with the casing, a pivoted hopper, and eonneetions between said hopper and sca1e-bea1n for moving the mouth of the hopper alternately over the boxes, substantially as and for the purpose set forth.
