WEIGHING SYSTEM Filed Aug. 9, 1932 2 Sheets-Sheet 2 I I a a; F

BY ATTORNEYS place by means of wing-nuts 40 on bolts 4|. Bowsprings 42 straddling the openings and engaged by the nuts 40 hold the plates in fluid-tight engagement with the inner surface of the side plate of the buckets, in which the overflow-openings are formed.

Beneath the bucket at its overflow side is a receiver 43 for the overflowing liquid. The oil or asphalt is supplied to the bucket from a conveniently located source of supply, and a conduit shown at 4511, returns the contents of the receiver to the source in a substantially closed circuit. It

will be understood without detailed illustration that a pump or other similar device may be employed for this purpose. The source has been shown in broken lines at 44 in Figure 2 and a pump has been indicated at 45.

A spout 41 conducts the material from the source to the bucket, and a gate valve 48, provided with a handle 49, controls the flow through the spout 41. The handle 49 preferably extends over the bucket so that it may be reached by the operator who tilts the bucket by means of the handle 32.

In the operation of the measuring bucket, the empty bucket is weighed first of all, after which the weighing scale is set to balance the bucket and the quantity of oil or asphalt constituting the batch to be delivered to the pug mill in each operation.

The liquid is then poured into the bucket from the source of supply until the weighing scale is in balance, after which the overflow opening or openings nearest the level of the liquid are opened by removal of the respective cover-plates.

The bucket is then tilted rearwardly, as indi cated in broken lines in Figure 2, until the level of the liquid is in alinement with the lower edges of the uncovered openings and the set screws l3 are adjusted to engage the stops M in this position of the bucket. It will be apparent that after these adjustments have been made, the bucket may be repeatedly filled until the liquid flows out of the uncovered openings and that each time the weight of the contents of the bucket will be equal to that originally determined by means of the weighing mechanism.

The overflowing liquid drops into the receiver 43 and is returned without loss, the bucket having at the bottom of its rearward side, a trough 46 to catch drippings and convey them to the receiver. The'bucket is emptied by tilting it forwardly by means of the handle 32, as hereinbefore explained, and it is automatically returned to its original position in which the stops engage the ends of the set screws, by the counterweights I5.

I The opening 3| at the top of the bucket controlled by theadjustable gate, permits the discharge of the liquid in a thin stream, it being desirable that the length of the bucket be but slightly less than the width of the pug mill or other receptacle into which the liquid is dumped.

What I claim and desire to secure by Letters Patent is:

1. In apparatus of the character described, a

"suspension bail, a bucket pivoted in the bail and having overflow openings at difierent elevations, removable closures for the openings, and means for limiting pivotal movement of the bucket, to establish a liquid-level in alinement with one of the overflow-openings, including a set -screw on the bail, and a stop on the bucket, engaged by the set-screw. Y

2. In apparatus of the character described, a pivoted bucket having an overflow-opening on one side of the pivot for establishing a predetermined liquid-level in a position of rest of the bucket, and having a discharge-opening on the other side for the delivery of its contents in a tilted position, means comprising a stop establishing said position of rest of the bucket, and an adjustable counterweight opposing movement of the bucket out of its position of rest.

3. In apparatus of the character described, a pivoted bucket having an overflow-opening establishing a predetermined liquid-level in a position of rest of the bucket, and having a discharge opening for the delivery of its entire contents in a tilted position, the discharge-opening extending substantially along an entire side of the bucket, and 15 flow-restricting means limiting the width of the discharge-opening.

4. In apparatus of the character described, a pivoted bucket having an overflow-opening establishing a predetermined liquid-level in a position 20 of rest of the bucket, and having a dischargeopening for the delivery of its entire contents in a tilted position, the discharge-opening extending substantially along an entire side of the bucket, and an adjustable gate limiting the width of the 25 discharge-opening.

5. In apparatus of the character described, a pivoted bucket having one side provided with an overflow-opening establishing a predetermined liquid-level, and having the other side provided 30 with an opening for the discharge of its contents while in a tilted position, a source of liquid-supply, a receiver for overflowing liquid, and means for returning liquid from the receiver to the source.

6. In apparatus of the character described, a pivoted bucket having an overflow-opening on one side of the pivot for establishing a liquid level in a predetermined position of rest of the bucket, stop-means determining said position of rest, a downwardly slanting arm on the same side of the pivot as the overflow opening, and a weight on the arm effecting movement of the bucket to its said position of rest and opposing its movement therefrom, the bucket being adapted to discharge its contents in a tilted position.

7. In apparatus of the character described, a

pivoted bucket having an overflow opening on one side of the pivot and normally at a given distance above its bottom for removal of the contents of the bucket in excess of a measured quantity, and means for adjusting the bucket about its pivot, whereby to dispose the opening at a different elevation above the bottom to vary the measured quantity.

8. In apparatus of the character described, having a Weighing element, a pivoted bucket suspended from said element and having an overflow-opening normally at a given distance above its bottom for removal of the contents of the bucket in excess of a measured quantity and having a discharge-opening on the other side of the pivot to effect the delivery of the measured quantity from the bucket, and means for adjusting the bucket about its pivot, whereby to dispose the overflow-opening at difierent elevations above the bottom to vary the measured quantity.

9. In an apparatus of the class described, a support, a bucket pivotally connected thereto, for rocking movement about the pivot, an adjustable stop for limiting the rocking in one direction while permitting it to be rocked freely in the other direction to efi'ect a discharge of the contents thereof, the side of the bucket corresponding to the limited rocking movement having a plurality of overflow openings located at different levels and provided with removable closures for eifecting a major adjustment of the capacity of the bucket, and means comprising the adjustable stop for efiecting a simultaneous vertical adjustment of all of the overflow openings to effect a more delicate adjustment of the capacity of the bucket.

10. In an apparatus of the class described, in combination, a support, a bucket pivotally connected thereto, the bucket being freely rockable in one direction to effect a discharge of its contents, a stop for limiting the rocking in the other direction, the side of the bucket corresponding to the limited rocking movement having an overflow opening, means for adjusting the vertical position of the opening with respect to the pivot, to vary the capacity of the bucket when the stop is eifective, and means for urging the bucket into stopengaging position.

11. In an apparatus of the class described, in combination, a support, a bucket pivotally connected thereto, the bucket being freely rockable in one direction to effect a discharge of its contents, a stop for limiting the rocking in the other direction, the side of the bucket corresponding to the limited rocking movement having an overflow opening, means for adjusting the vertical position of the opening with respect to the pivot, to vary the capacity of the bucket when the stop is effective, and means for urging the bucket into stopengaging position, said means consisting of a weight located on the same side of the pivot as the overflow opening.

12. In an apparatus of the class described, in combination, a supporting-element, a bucket pivotally connected thereto, one side of the bucket having an overflow opening and the opposite side a discharge opening, adjustable stop means for limiting the pivotal movement in the direction of the side having the overflow opening while permitting the bucket to rock sufficiently in the other direction to effect a discharge of its contents, the bucket being overbalanced for the purpose of normally making the stop effective, and means comprising the adjustable stop for adjusting the vertical position of the overflow opening to vary the capacity of the bucket.
