GRAIN-METER;

SPECIFICATION forming part of Reissued Letters Patent No. 9,213, dated May 25, 1880.

No. 137.921, dated April 15,1873. Application foireiss'ue filed September 29, 1879.

. To all whom it may concern r gomery and State of Ohio, and now a resident ofCineinnati, countyof Hamilton, and State of Ohio, have invented certain Improvements in Automatic Grain-Weighers, of which the following is a'specification.

The nature of my invention consists, first,

in an automatic grain-weigher, a grain pan or bucket freely suspended from a steelyard or balance-beam, and provided with devices for retaining it in position for the reception of grain, in combination with a tripping device coming in contact with said retaining-devices mit the discharge thereof, and a positive-cutofi" operated by but opposing no resistance to the movementof the pan in overbalancing the counterpoise-weight; second, in a novel device for sweepingthe grain fronrthe cut-oif valve or plate as it is withdrawn from the :spout.

In theaccompanying drawings, Figure 1 and connected mechanism.

The same letters of reference are used in parts.

The various operating parts of the machine are mounted upon a convenient frame-work, A,- whicl1 is provided with'a suitable opening in its base beneath the scale-pan of the balunce, to permit of its oscillations and the discharge of the grain.

The long arm B of the beam of the balance carries the usual adjustable sliding weight B, and is secured firmly to the shaft B which terminates at each end in a knife-edge, resting in bearings 11 on the side timbers of the frame. Near each end of this shaft is fastened an arm, 13, extending in an op site direction to that of the arm B, and cons ituting the short arms of the beam.

Each arm B is provided witha laterallyprojecting knife-edge near its outer end, from which the suspension-rods U and C are suspended. The scale pan or bucket D is hung between these suspension-rods, the lower ends of which are pivoted to projecting studs d on. the pan. Thelatter has adouble-inclined bot tom, open ends,-and a central partitiom D, '55, dividing it into two compartments, which are used alternately for weighing the desired quantity of grain. I p The pa n, isheld steadily between the suspension-rods until it has received the weight of grain required, either in theposition shown in Fig. 2 or that illustrated-iii Fig. 3, by

'means of detents E on the suspension-rods and sectoral catchesf or cheeks F on the scalepan. y The detects oonsisteachof a lever, which. ispivoted at one end toa projecting arm, a, of the suspension'rods, and has projecting from it, about midway of its length, a stud, e, which engages automatically either with t-henotch f or the notch f of the corresponding catch F, according to the position of the pan, by falling into the same by gravitation. The ex-v treme freeeud of each detent is providedwith an outwardly-projecting stud, e, overhanging a fixed bracket,-E, on the frame, with which it comes in contact on the descent of the pan, whereby the detent is lifted so as to elevate its stud 0 out of the notch of the catch. The moment this is accomplished the pan is osc' lated by the weight of the grain in one of'i-ts compartments, and the grain being discharged limited by stirrups c, in which the knife-edges on the short arms of the beam move, and it is just sufficient to cause the release of the detents from the notches of the catches at the proper times. Without some means for checking this descending motion of the pan it might descend so far as to lift the studs e of the detents abovethe shoulders f on the too a minimum.

The open'end of the spout is controlledby f a cut-off, H, fastened to the rods H H, which in turn are secured to a rock-shaft, H turnn g. in hearings on the hopper. The rock-shaft carries .a weighted arm,'H the outer end of which rests upon a stud, b ,'on the standard b which is adjustably secured to an elongation. b, of the arm B. As the beam is turned by the weight of the grain in thescale pan or bucketthe cut ofl' is moved under the-spout by the action of the weighted arm H stopwithdrawn.

ping the flow of grain during the oscillation of the pan, and on the descent ot' the arm B the cut-ofi' is drawn back from under" the spout by the action of the elongation or arm b upon theweighted arm H.

The cut-ofl' is adjustably secured to the rods --H for vertical adjustment, and its throw is regulated by the adjustable standard b, to adapt it for operating in difi'erent kinds of grain and seeds. j

-.A scraper, I, consisting of a strip of leather, india-rubber, or'a brush, is used. to sweep 011' from the cut-off any grain or seedsas it is The downward movement of the arm B of the beam is-limited by the post K, which may be provided with a pin, k,-ou top, resting'with its head upon an ela'sticcushion, k, to take up the shock as thebeam comes down on the pin.

What I claim is x 1. Anautomatic grain-weigher consisting, essentially, of a grain pan or bucket, as D, freely suspended from a steelyard or balancebeam, and provided with devices for retaining it in position for thereception of grain, a fixed grain-spout, as G, dischargiugdirectlyinto the bucket D, and a positive cnt-ofl', as H, to stop the flow of grain when the weighed quantity has been taken, which is closed by the descent of the grain-pan,'in combination with tripping devices for causing vthe discharge 'of the weighcd grain, substantially asspein'fied.

2. The combination of the freely-suspended grain pan D, suspension-rods O U, detent-s E 3. The combination of the freely-suspended grain-pan hung upon thesuspension-rods O O of the beam of the balance,'fixed catches on said pan, gravitatingdetents on the suspension-rods, and fixed brackets E, substantially as specified. 7

4. The combination of the freely-suspended grain-pan hung upon the suspension-rods C G of the beam-balance, thefixed catches on said. balance, the gravitating detents on the suspension-rods, fixed brackets E, the stirrups c, and the shoulders f on the checks or catches, substantially as and for" the purpose set forth.

In testimony whereof I have hereunto set my hand this 27th day of September, 1879.
