GRAIN-SCALE.

EPECIFIEOATION forming'part of Letters Patent No. 3493257, dated September 21,1886.

Application filed January 13, 1886.

T0 (tZZ whom it may concern.-

Be it known that I, KAsrEn H. Senarnn, ot'Linns Hills, Lincoln county, Missouri, have made a new and useful Improvement inG rain Scales, of which the following is a full, clear, and exact description.

The present construction is an improvement in that class of grain-scales having a weighinghopper adapted to be balanced to receive any Iixed weight of grain, and when the desired amount has been admitted thereiuto to drop, and thereby cause the bottom of the weighing hopper to open and the grain to be discharged from the hopper.

The improvement consists in the weighing hopper having compartments into which alternately the grain is received and thence discharged, in combination with the means for directing the admission of the grain into the compartments and its discharge therefrom, substantially as is hereinafter set forth and claimed.

In the annexed drawings, making part of this specification and exhibiting the improvement, Figure 1 is a side elevation of the scale. Fig. 2 is an end elevation, the parts being as in Fig. 1. Fig. 3 is view similar to that of Fig. 1, but showing the weighing hopper dropped and the opposite compartment-bottom opened; and Fig. rt is a vertical section on the line st i of llig. 2.

The same letters of reference denote the same parts.

The present graiuseale can be used by itself or in combination with other mechanisms such as employed in mills using grain, or such as are used in handling or treating grain. In the present instance the weighing-hopper A is shown supported by the frame 13, the frame being in the form of the uprights I) I), arranged at opposite sides, respectively, of the weighinghopper, and connected therewith as follows:

0 represents a scale-beam, whose outer end, 0, is in the form of an ordinary scalebeam, and whose opposite end is forked, the forks c c, by means of the knife-edges 0, being held and adapted to rock in bearings Z) in the uprights I), and the weighing-hopper, by means of the knife-edges (1 ,being h ung in the forks c c,and so that b Y means of a wei ht I) the wei hin D 7 7 O b Serial No. 185,356. (No model.)

hopper can be weighted to receive the desired quantity of grain before it shall drop and bear down the forked end of the scale-beam. The weighing-hopper at its upper end has an opening suitably shaped to admit the grain to be weighed.

The weighing-hopper, by means of a partition, a, is divided into two compartments, (6 a, Fig. 4. A valve, a, is jointed to the partition at its upper end, and the valve, as indicated by its two positions, shown, respectively, in the full and in the broken lines in Fig. 4, can be turned upon its hinge so as to form an opening into one, a, of the compartments, and meanwhile close the entrance into the opposite compartment, a", or to close the entrance into the compartment a and open that into the compartment a"that is, when the valve is turned into the position of the full lines, Fig. 4-, the grain drops through its opening a into the compartment a, as indicated by the arrows shown in the full lines, and when the valve is turned the opposite way the grain falls through the opening a into the compartment 0 Each compartment has its own bottom. That, a", of the compartment a is hinged at the point a, and the bottom a of the compartment a is hinged at a The two bottoms a e are connected, so that when one of them is opened the other is closed. This is ell'ected as follows: E represents an arm that is fastened to an extension, a", of the shaft a, to which the valve a is attached. This arm, at its ends, respectively, and by means of the swinging rods F G, respectively, is connected with the bottoms of a Then when one-say the bottom w"is depressed by the weight of the grain upon it, that end of the arm E with which that bottom is connected is drawn down with the bottom, and the valve a is turned with the arm E, and so as to deflect the grain into the compartment a, to rest upon the bottom a and when that bottom a is depressed the arm E and valve a are turned in the opposite direction. The bottoms open when the fixed weight of grain has accumulated upon the bottom. The weighinghopper at the same time also drops. The arm E has an extension, 0, extending upward. It operates in connection with a fixed shoulder, H. As long as the hopper is in its elevated position, the shoulder, as shown in Figs. 1, 2, is against one side of the extension e, and the arm E in consequence cannot be moved; but when the weighing-hopper drops the extension 6 is no longer held by the shoulder H, and the arm E and valve a are free. As each compartment then is filled, the weighing-hopper drops, the bottom of that compartment which has been filled opens, and the grain therein is discharged from the and by reason of the opening of the bottom the valve a is changed and the bottom of the opposite compartment is closed. Immediately following this the hopper rises again, bringing the opposite side of the extension 6 against the shoulder H, again confining the arm E and valve a until the lastreferred-to compartment is" filled with the grain, and so on, directing the grain first through one and then through the other of the compartments. The shoulder H may be supported in the position shown by any suitable means-as, for instance, by means of the arm I, which in turn is supported from the frame 13. The arm J serves to keep the hopper vertical as it moves upward and downward, as described. A special advantage derived from'this construction is, that the flow of the grain into the hopper is, by the means described, at once deflected to and fro into one compartment and the other, so that the grain is accurately weighed.

compartment, and with The movementof the hopper as it falls can be registered in any desirable manner.

I am. aware that it is not broadly new in devices of this description to divide the hop- 5 per or grain-receptacle into two parts, each having a hinged bottom, and said bottoms provided with rods connecting with the valves at the lower end of the induct to the hopper, whereby the grain can be automatically fed into one chamber of the hopper so soon as the other is filled. r I claim- The weighing-hopper having a valve in its opening, and two compartments, and the hinged bottoms at the lower end of the compartments, respectively, in combination with the swinging rods F and G, pivoted at their lower ends, respectively, to the hinged bottoms a and a of said compartments, and at their upper ends, on opposite sides of the arm E, fastened to the shaft a of the valve-ain the opening of the hopper, said arm having the extension 0, the fixed shoulder H, the frame B, the beam 0, and the weight D, as described.
