To aZ 'whom t may concern: in.

Be it known that l, CHARLES H. COOLEY, a spout is swung over the closer, as at the left citizen ot' the United States, residing at Harthand of the figure drawing, comes down ford, in the countyof Hartford and State of close to the closer, as there shown, and thus 55 Connecticut, have invented certain new and prevents the escape at that point of the grain useful Improvements in Grain-Veighers, ot which lies in the spout and on the closer. On which the following is a specication. the outer edge of the closer a xed rim 73 is This invention relates to automatic grainprovided as a guard for preventing' overtlow Weighers, and has Afor its object to furnish imat that point, also rims, as 52 and 5i, at the 6o lo proveniente in the bucket mechanism of the ends of the closer.

According to my present improvements the My present improvements are intended for flat closer 33 is set oblique to the line ot moveuse in connection with grain-weighers of the ment of the spout over a closer, so that as the class described in Letters Patent No. M2; .13, bucket moves in the direction of the arrow a 65 granted to me December 16, 1890, to which the edge a will approach the lower edge 3 of reference may be had for such parts otl the the closer 33 at a considerable angle,substan grain weigher as are not herein fully detially as shown, so that on the reverse moveseribed. nient of the bucket said wall 4 leaves said In the drawing accompanying' and forming edge 3 gradually and with a constantly-widen- 7o 2o a part of this specification is shown a side eleing space between them from the very instant vation, partly in section, of a grainbucket of the openingmovement, thus preventing on mechanism embodying my present improvethe opening of the bucket any possibility of ments. wedging` the split and wedge-shaped kernels For convenience of reference the several of grain between the two edges 3 and et. In 75 2 5 parts are herein designated by the same reforder to extend this principle of operation to creme-characters as are used to designate the entire width of the spout, and thus render the corresponding parts in said prior applivery certain the proper action of the spout cation. and closer, I form the upper line of the closer The numeral 19 designates one ot' the at right angles to a line from the axis l2 8o 3o bucket-supporting arms of the scale-beam, through the closer beyond the spout Sat, said which arm is furnished with the usual kniteline being radial to the axis l2 and desigedge l5 for carrying the hanger 1C, whose upnated by Z) l). lVith the axis l2 as a center, per end is shaped substantially as shown vfor draw now the line c o, touching the surface of suspension on said knife-edge.

It will of course be understood that the closer 35 and spout 36 are or may be constructed upon the same principle, but oppositely disposed to the vertical plane through the axis l2 and the knife-edge 15.

Having vthus described my invention, I claim- I. In agrain-weigher, the eombination,with the bucket-supporting hangers and with the oseillatin g bucket carried in said hangers and having discharge-spouts, substantially as described, of the closer-plate carried by the hangers and set tangential at a point substantially coincident with the upper side of the closed spout to a circle concentric with the bucket-axis, the lower edge of the closer being contiguous to the lower side of the closed spout, whereby the spout begins at once to open for the free discharge of the grain on the beginning of the bucket movement.

2. In a grain-weigher, the combination, with the hangers and the oscillating double-'chambered grain-bucket supported thereby and having oppositely-disposed dischargc-spouts, substantially as described, of the two oppositely-disposed bucket-elosers, each set in.
