GRAIN WEIGHER AND SACKER.

SPECIFICATION forming part of Letters Patent No. 561,742, dated June 9, 1896.

Application filed April 6, 1895. Serial No. 544,763. (No model.)

To aZZ whom it may concern: thrown back and forth. This trip-lever is Be it known that I, JOSIAH M. TELBOURN, the lower part of the weigh-beam l3 and has a citizen of the United States, residing in its lower end made with open jaws j j, which the county of Morrow, in the State of Ohio, engage the crank O, as shown. Its upper end 5 have invented anew and useful Improvement is fastened to and preferably made a part of in Grain YVeighers and Sackers, of which the the weigh-beam B, which is a beam having following is a specification, reference being on it an adjustable movable pea I, which had to the annexed drawings, and to the figregulates the weight to be put into the sack by ures and letters of reference marked thereon, shoving it up or down 011 the beam 13.

Between this pivotal connection and the end My invention consists in mechanism by of the lever is suspended the bag or sack which grain is gradually run into sacks or holderH, which consists of thebox K, adapted 20 other receptacles as it comes from the chute t0 telescope the ends of the outlet-chutes a and, when filled to the desired weight, by and a, and jaws or clamps m m, fitting down which a valve is tripped in the throat of the upon shoulders 01 n on the lower end of the chute and the flowing grain is directed from box.

This shaft is provided with a crank X X are bars fixed to the box at the upper 45 O at one end which engages a trip-lever T, and lower ends and serve to strengthen the which when it moves back and forth trips box as well as to provide a support for the 5 the crank O and shifts the valve back and levers L L and has stops 8 s, which are adforth with the lever T, and thus shuts one justably clamped or otherwise adjustablyseoutlet and opens the other as the trip-lever is cured thereto at points between the upper and lower ends. These stops 5 s serve to arrest the movement of the beam B. This beam B is pivotally connected to the boX, on about the vertical center, by means of a shaft B, which passes through the boX.

S is a bag or sack clamped to the holder H and is swung clear of the floor while being filled and weighed. The valve is provided with flange Y on its side, projecting upward and adapted to pass up behind the guards Z on the inside of the throat, which prevents the grain from getting in between the side of the throat and the valve and preventing it from working.

The operation of this device is so apparent from the above description that I do not deem it necessary to say more than that when the bag is clamped, the holder and the bar B is thrown to the left, and the pea is run up the bar for the desired weight to be put in a bag, and the throat or inlet is attached to the chute of a threshing-machine or other grain or flour chute, the machine is ready for use, and as the grain runs down into the suspended bag it fills in tightly and compactly, and when the desired weight is in the bag or suspended sack it pulls down the lever L, which pulls the lug Z and trips or throws the beam B beyond its perpendicular to the right, and by its own weight it falls to the stop on the right, where it is arrested. It at the san e time en gages with its jaws the crank O, which throws the valve to the left in direction of the dotted lines, which cuts the flow of grain off the righthand outlet withou t checking the flow through the throat of the machine. \Vhen it is turned thus into the left-hand outlet-chute, it proceeds to fill the bag there attached. Then it has filled this bag, the left-hand lever pulls down on the left-hand lug on beam B and throws it to the left and directs the grain again into the right-hand outlet-chute, which has been replenished in the meantime with an empty bag. Thus the machine automatically operates weighing and filling the sack. This gradually filling the sacks by the gradual flow is of great advantage over other machines where it is dumped in by the half-bushel or dumps of any size, because there is no backing up of grain or flour in the throat of the machine, but it is always free, and because of this gradual flow the sack is filled out full in all its parts and thoroughly packed. Neither is the bag liable to be torn or jerked from its holder, as is often the case where dumps are made into a suspended sack.

The figures 1, 2, 3, andat are a series of pawls and wheels, arranged, as shown, to make a registering device which is a common registering device applied to my machine, and I claim nothing new for it except as applied to this new machine for weighing and sacking grain.

The pawl 1 is hung 011 the lever 5, which is pivotally connected to the boX A and is provided with a slotted hole-and-pin connection to the weighted beam B, so that it will move the pawl 1, and consequently the ratchetwheel 2, whenever the lever is thrown to the right. This wheel is journaled on the box A and is provided with a registering-hand 6, which registers two points every time the beam 13 is thrown to the right. This ratchet wheel 2 is provided with a pin '7, which is adapted to engage a lever 8, which lever is pivotally connected to the box A and has a pawl 3 at its upper end and has its lower end adapted to engage the pin 7, which pin at each revolution of the wheel 2 moves said lever and pawl and causes the registeringhand 9 to register one point 011 its dial.

is a dial for the hand 9, and 11 is a dial for the hand 6. The dial 11 has one hundred points and the dial 10 has any number of points, so that when the register-hand 6 has registered one hundred bags the register-hand 9 registers (1) one. It registers the hundreds while the other registers the bags from 1 to 100.

Now what I claim as new, and for which I wish Letters Patent to be issued to me, is-

1. An automatic weigher and sacker comprising a stationary main throat or chute, two auxiliary chutes in combination therewith, two movable open-ended uninterrupted bag-holders at the lower ends of said chutes, bags suspended from the hooks a weighted lever connected with and operated by the weight of the filling bags through the medium of the said open-ended uninterrupted bagholders, and a shifting-valve at the junction of said main and auxiliary chutes operated through the medium of the said bag-holders, substantially as described.
