CONVEYER-BUCKET.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application led October 9, 1908. Serial No. 456,929.

To all whom t may concern:

Be it known that I, JAMES BARBOUR GIB- soN, a citizen of the United States, residing at lVebb City, in the county of Jasper and State of Missouri, have invented a new and useful Conveyer-Bucket, of which the following is a specification.

This invention relates to buckets or cups of that general type employed on endless conveyers.

The principal object of the present invention is to provide improved form of bucket in which the expense of renewal or repair may be reduced to a minimum.

A further object of the invention is to provide a novel form of bracing means for connecting the front and rear walls of the buckets of large size.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claim, it being understood that various changes in the form, proportions, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings Figure 1 is a transverse sectional view of an elevator bucket constructed in accordance with the invention. Fig. 2 is a perspective view of the body section of the bucket. F ig. 3 is a similar view of the front or digging section detached.

Similar numerals of reference are einployed to indicate corresponding parts throughout the several figures of the drawmos. Y

zThe body portion of the bucket is formed of a single sheet of metal so cut and shaped as to form a back 10, a bottom 11, and end members 12. The end members 12 are quadrilateral in form, having parallel upper and lower edges, but the upper edges are of much greater width than the lower edges. In cutting out the blank, provision is made for the formation of a pair of flanges 13 which project from the ends of the bottom 11, and which are subsequently bent up outside of and parallel with the end members, and united to said end members by rivets or other fastening devices 14. The forward edge of the bottom is extended and is bent upward to form a flange 15, that constitutes a portion of the front wall of the bucket, and the ends of this flange 15 are provided with wings 16 that are bent inward in parallel relation with the end members 12, and which t between the outer faces of said end members and the inner faces of the flanges 13, and are held in place by the rivets 1/1.

The front section of the bucket, as shown in Fig. 3, is preferably formed of heavier metal than the body. This front section is, also, formed of a single piece of sheet metal and has a front plate 17, the opposite side edges of which are bent at a right angle to the plate to form a pair of flanges 18 that extend within the end members 12 of the body section. The lower edge of the front plate 17 is bent to form a lower flange 19 which, when in position in the body, will rest directly on the bottom 11, the angular relation of the flange 19 to the plate 17 being precisely the same as the relation of the bottom 11 to the flange l5, so that the lower portion of the front section may be seated firmly within the body and the lower flange 19 will be in position to receive the initial impact of the load entering the bucket. The front section 17 is secured in place in any suitable manner, but preferably the flanges 18 and end members 12 are provided with openings 20 for the passage of securing bolts 21 that are provided with nuts which may be readily removed when the front or digging edge becomes worn or broken, and must be replaced.

In buckets of large size, it becomes advisable to provide a means for bracing the front or backing wall and for this purpose a bolt 25 may be used. This bolt extends through suitable openings formed in the front and rear walls of the bucket, the headed end of the bolt bearing against the rear face of the rear wall, and the threaded end of the bolt being arranged to receive a pair of washers 26 and nuts 27, there being one washer and one nut at each face of the front section. Those faces of the washers in contact with the front section are cut on oblique lines, so as to lit tightly against both walls of the front section without injuring the saine.

What is claimed is In a conveyer bucket, a body section formed of a single sheet of metal, and comprising a rear plate, a bottom and end members, the ends of the bottom being turned l form flanges that ft Within the end portions up to form flanges parallel With the end members, and the front of the bottom being bent upward to form a front flange, the ends of said front flange having Wings that fit within the flanges of the bottom, securing means extending through openings formed in the end flanges, Wings and end portions, a detachable front section formed of a single sheet of metal, and comprising a front plate, the opposite side edges of which are bent to of the body section, and a base flange a1'- ranged to rest on the bottom of the body section.

In testimony that I claim the foregoing as my own, I have hereto aHiXed my signature in the presence oftwo Witnesses.

JAMES BARBOUR GIBSON.'
