CHESTER L. 'WYLIE, OF VALLEY CITY, NORTH DAKOTA, ASS IGNOR OF TWO- THIRDS TO OLE P. ENERSON, OF SAME PLACE, AND SMITH B. CLARY, OF

FARGO, NORTH DAKOTA.

GRAIN-METER.

SPECIFICATION forming part of Letters Patent No. 521,904, dated June 26, 1894.

Application filed January 22, 1894. Serial No. 497,662. (No model.)

T0 at whom, it may concern.-

Be it known that I, CHESTER L. WYLIE, a citizen of the United States of America, residing at Valley City, North Dakota, have invented certain new and useful Improvements in Grain-Meters, of which the following is a specification, reference being had therein to the accompanying drawings.

This improvement relates to that class of grain meters wherein a hopper having two openings is employed, which are alternately opened and closed by the same door, and the invention consists in the peculiar construction, arrangement and combinations of parts hereinafter more particularly described and then definitely claimed.

In the accompanying drawingsFigure 1 shows a side view of a meter constructed according to my improvement. Fig. 2 is a similar view showing part of the same in another position. Fig. 3 is a view of the scale box and some of the parts detached, taken at right angles to the views shown in Figs. 1 and 2. Fig. 4 is a plan of a forked lever. Figs. 5 and 6 are face and edge views of a lever detached. Fig. 7 is a side view of the scale box detached with one side removed. Fig. 8 is an end view of the same also detached. Fig. 9 is a plan of a pair of stops. Fig. 10 is an elevation of the same.

Referring now to the details of the drawings by figures, 1 represents an elevator of any ordinary construction, to which is pivoted at 2 a forked lever or beam 3, and from the ends of the forked part of which hang rods 4. Suspended by a pivot or pivots on these rods is a hopper or scale box 6, having a division 7 in the center, two openings 8 and 9 at the bottom and a swinging door 10, as shown in Fig. 7. At the top on each side is a lug 11, which engages (as will be hereinafter explained) with stops 1'), 13, pivotally connected to the elevator or to a plate 1' attached thereto. Each of these lugs has a pin 14 which enters a hole in the top of one of two levers 15, each of which is pivoted near its center at 16 to one of the rods 4. Each lever has on its lower half a large opening 16 to admit of the pivots 5 passing through and to allow of the swinging of the lower part of the box or hopper. It also has a small hole to receive a pin 17 on the bottom of the door 10. The

stops

12 and 13 are preferably provided with anti-friction rollers 12' 13 on their outer ends to avoid friction, and are pivoted together at their inner ends by a pin 4 set in the rod 4. The holes in which said pin works are elongated to prevent binding as the stops are raised and lowered when in operation. A brace 18 is shown connected to the elevator and the rod 4, but any other means may be adopted to keep these rods in a substantially vertical position.

Hanging from the lever 3 is a weight 19 which should be sufficiently heavy to countel-balance the weight of the hopper, &c.,and that of the quantity of grain to be weighed at each operation of the meter.

Below the scale box 6 is a directing hopper 20, having a movable partition 21, which may be turned toward either side so as to direct the grain into the desired leg of the hopper, according to whether it is desired to bag the grain or to raise the same by an elevator 22.

The operation is as follows: The hopper being in the position shown in Fig. 1, the door will be kept closed by the stop 13 and the grain drops from the elevator or 0ther wise into the left hand side of the box 6, until that side has sufficient in it to overcome the weight 19, when the box will descend, and as the lug 11 drops below the stop 13, which will be raised by the pin 4 double the dis tance said pin falls, the weight of the grain will cause the box to turn on its pivot 5 over to the opposite side and the door 10 to-also swing to the opposite side, and open opening 8 and close the opening 9 on the other side, thus allowing the grain to descend through opening 8 into the hopper below. As the scale box becomes empty it rises and the lug 11 passes up alongside the stop 12 which descends, as the scale box, rod 4 and pin 4' rise, and as soon as the other side of the box has sufficient grain in it, the operation is repeated, the parts again assuming the position shown in Fig. 1.

I do not wish to limit myself to the particular form of stops shown, as other forms may be used without changing my invention.

What I claim as new is- 1. In a grain meter, a double scale box having two egress openings, a door closing each of said openings alternately, a counterbalanced beam from which the scale box hangs, rods connecting the beam and the box, in combination with a lever pivoted to said rods and having one end connected to the scale box and the other to its door, substantially as described.

2. In a grain meter, a double scale box, having two egress openings therein, a door closing each of said openings alternately, a counterbalanced beam from which the scale box hangs, and rods connecting said beam and scale box, in combination with a lever having its opposite ends connected to the box and the door thereof, and provided with an opening to admit of the passage of the pivots supporting the box, substantially as described.

3. In a grain meter, a double scale box having lugs near its top and two egress openings in its bottom, a door closing each of said openings alternately, a counterbalanced beam from which the scale box hangs, and rods connecting said beam and scale box, in combination with a lever pivoted to the rods and having its opposite ends connected to the box and the door thereof, and stops to engage with the lugs 011 the box, substantially as described.

4. The combination in a grain meter, of an elevator 1, having stops 12, 13, a counterbalanced beam 3, rods 4-. hung therefrom, a double scale box 6 pivoted to said rods, and having lugs 11, a door arranged to close the egress openings in said box alternately, levers pivoted to the rods 4 and having their opposite ends connected to the box and its door, substantially as described. 7

5. The combination in a grain meter, of an elevator 1, having lever stops 12, 13, a counterbalanced beam 3, rods 4: hung therefrom and having a pin for operating said lever stops, a double scale box 6 pivoted to said rods and having lugs 11, a vibrating door arranged to close the egress openings in said box alternately, levers 15 pivoted to the rods 4 and having their opposite ends connected to the box and its door, all substantially as shown and described.

In testimony whereof I aflix my signature, in presence of two witnesses, this 16th day of January, 1891.

CHESTER L. WYLIE.
